Latent hinged flap for plastic window

Technical field

The invention belongs to the parts technical fields of window, are related to a kind of latent hinged flap for plastic window.

Background technique

Currently, the hinge of plastic window have latent hinged flap, can not the board-like hinge of mode and plug-in type hinge.Latent hinged flap refers to When sash is in and closes, the interior external visual face of sash does not see hinge, and this latent hinged flap does not destroy the sealing system between frame fan, Energy saving is better than other hinges.The latent hinged flap of general plastic window be mostly it is non-adjustable or one-dimensional, two dimension is adjustable, i.e., sash is with respect to window Frame is irremovable or unidirectional, bidirectional modulation is mobile, adjusts there are limitation, leakproofness is poor.For this purpose, it is necessary to designing one kind Latent hinged flap, to solve the above technical problems.

Summary of the invention

The object of the present invention is to provide a kind of simple latent hinged flaps of structure, install the plastic window of the latent hinged flap, window Fan opposite frame is convenient to carry out mobile adjusting, to improve the leakproofness of plastic window.

In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: a kind of latent hinged flap for plastic window, Including upper hinge mechanism and lower hinge mechanism；

The upper hinge mechanism includes upper fixed block, the first upper connecting rod, the second upper connecting rod, third upper connecting rod, connects on the 4th Bar and upper mounting plate, the fixed block are connect with first upper connecting rod, and first upper connecting rod and second upper connecting rod connect It connects, second upper connecting rod moves in first upper connecting rod, is set with eccentric nail in first upper connecting rod, described Third upper connecting rod is equipped with through-hole, and the eccentric end of the upper eccentric nail protrudes into the through-hole, the third upper connecting rod and upper peace Loading board is rotatably riveted with second upper connecting rod respectively, the both ends of the 4th upper connecting rod respectively with the third upper connecting rod and Upper mounting plate rotatably rivets；

The lower hinge mechanism includes connecting under lower fixed block, the first lower link, the second lower link, third lower link, the 4th Bar and lower installation board, the lower fixed block are connect with first lower link, and first lower link is equipped with lower eccentric nail, institute The both ends for stating the second lower link are rotatably riveted with first lower link and third lower link respectively, on the third lower link Equipped with the detent matched with the lower eccentric nail, the third lower link respectively can with the 4th lower link and lower installation board Rotation riveting, the both ends of the 4th lower link are rotatably riveted with first lower link and lower installation board respectively.

Further, guide pin is fixed in first upper connecting rod, second upper connecting rod is equipped with guide groove, described Guide pin protrudes into the guide groove.

Further, the upper fixing block is connected by screw in one end of first upper connecting rod.

Further, the lower fixed block is connected by screw in one end of first lower link

The invention has the advantages that: latent hinged flaps of the invention, and overall structure is simple and practical, through upper eccentric screw under Eccentric screw, that is, variable sector fans the distance relative to window frame, easy to adjust quick, and sash is adjusted relative to the distance of window frame and closed After reason, the leakproofness of plastic window is improved.

Specific embodiment

Below in conjunction with attached drawing of the invention, technical scheme in the embodiment of the invention is clearly and completely described, Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all Belong to the scope of protection of the invention.

As shown in Figure 1, a kind of latent hinged flap for plastic window of the present embodiment is installed on the structural schematic diagram on window.It is hidden Shape hinge includes upper hinge mechanism 3 and lower hinge mechanism 4.

Referring to Fig. 2, upper hinge mechanism 3 in upper fixed block 31, the first upper connecting rod 32, the second upper connecting rod 33, third including connecting Bar 35, the 4th upper connecting rod 36 and upper mounting plate 37.Fixed block is connect by screw with one end of the first upper connecting rod 32.Connect on first Bar 32 is riveted by rivet and the second upper connecting rod 33, and the second upper connecting rod 33 can move in the first upper connecting rod 32.First upper connecting rod Eccentric nail 34 is rotatably set on 32, third upper connecting rod 35 is equipped with through-hole, and the eccentric end of upper eccentric nail 34 protrudes into through-hole It is interior.It is fixed with guide pin 38 in first upper connecting rod 32, guide groove is machined in the second upper connecting rod 33, guide pin 38 protrudes into guide groove It is interior.Third upper connecting rod 35 and upper mounting plate 37 are rotatably riveted with the second upper connecting rod 33 respectively.The both ends of 4th upper connecting rod 36 point It is not riveted rotatably with third upper connecting rod 35 and upper mounting plate 37.

Referring to Fig. 3, lower hinge mechanism 4 includes connecting under lower fixed block 41, the first lower link 42, the second lower link 44, third Bar 45, the 4th lower link 46 and lower installation board 47.Lower fixed block 41 is connect by screw with one end of the first lower link 42.First Lower eccentric nail 43 is set on lower link 42.The both ends of second lower link 44 respectively with the first lower link 42 and third lower link 45 Rotatably riveting.One end of third lower link 45 is machined with the detent 451 matched with lower eccentric nail 43.Third lower link 45 rotatably rivet with the 4th lower link 46 and lower installation board 47 respectively.The both ends of 4th lower link 46 respectively with the first lower link 42 and lower installation board 47 rotatably rivet.

When latent hinged flap of the invention is installed, upper fixed block 31 is fixed on the upside of sash, and upper mounting plate 37 is fixed on window The upper inside of frame.Lower fixed block 41 is fixed on the downside of sash, and lower installation board 47 is fixed on the lower inside of window frame.Of the invention is hidden Shape hinge Principles of Regulation are as follows: eccentric nail 34 moves the second upper connecting rod 33 along guide pin 38 in twisting, reaches the upper lateral of sash Window frame direction is mobile, to realize that Z-direction adjusts i.e. sealing and adjusts；Lower eccentric screw 43 is twisted, during sash is closed, under Eccentric screw 43 is matched with the detent 451 of third lower link 45, and lower eccentric screw 43 oppresses third lower link 45, and reaching makes The movement in the lower lateral window frame direction of sash further reaches Z-direction adjusting, i.e. front and back adjusts also referred to as sealing and adjusts.

To sum up, latent hinged flap of the invention, overall structure is simple and practical, is mounted with the plastic window of the latent hinged flap, Sash is convenient to carry out mobile adjusting relative to window frame, improves the leakproofness of plastic window.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
