技术领域technical field

本实用新型涉及门窗配件技术领域，特别是一种合页。The utility model relates to the technical field of door and window accessories, in particular to a hinge.

背景技术Background technique

如中国专利申请号201620115775.8的中国专利文献，公开了一份名称为“一种稳定性好的防火隐形合页”的技术方案，该方案的合页包括有固定座、连接座、主连杆、长连杆、短连杆、滑动轴、调节块、调节螺栓、若干铆钉、胶垫圈、铰接轴、定位螺钉，这种方案的固定座与连接座之间需要通过主连杆、长连杆、短连杆三条连杆进行连接才能实现门窗开合的功能；需要三条连杆进行连接这一方面增加了产品的制造成本，不利于企业的发展，另一方面增多了需要组装的零部件，降低了组装的效率，生产效率低；此外，主连杆与长连杆之间通过铆钉铰装一起，以至于使用时间长了，主连杆与长连杆之间会出现活动不顺畅的现象，但这种合页的主连杆与长连杆上并无设置有添加润滑油的结构，使得用户只能将润滑油添加在铆钉边缘上，通过反复活动使润滑油渗入到主连杆与长连杆的铰接处中，这样的方式润滑工序不仅繁琐，而且润滑的效果也不理想。For example, the Chinese patent document of Chinese patent application number 201620115775.8 discloses a technical solution titled "a fireproof invisible hinge with good stability". The hinge of the solution includes a fixed seat, a connecting seat, a main link, Long connecting rods, short connecting rods, sliding shafts, adjusting blocks, adjusting bolts, several rivets, rubber washers, hinged shafts, and positioning screws. The function of opening and closing doors and windows can only be realized by connecting three short connecting rods; on the one hand, the need for three connecting rods to connect increases the manufacturing cost of the product, which is not conducive to the development of the enterprise; on the other hand, it increases the parts that need to be assembled, reducing The efficiency of assembly is reduced, and the production efficiency is low; in addition, the main connecting rod and the long connecting rod are hinged together by rivets, so that the movement between the main connecting rod and the long connecting rod will not be smooth after a long time of use. However, there is no lubricating oil structure on the main connecting rod and the long connecting rod of this hinge, so that the user can only add lubricating oil on the edge of the rivet, and the lubricating oil will penetrate into the main connecting rod and the long connecting rod through repeated activities. In the hinge of the connecting rod, the lubricating process in this way is not only loaded down with trivial details, but also the effect of lubricating is not ideal.
