CN2404641Y - Bowl shaped tool for pulling-out oil block - Google Patents

The utility model relates to a bowl-shaped tool for pulling out oil block. The utility model is composed of an elastic sleeve barrel, a sliding rod, a weight dropper, and a handle. The lower part of the elastic sleeve barrel is provided with an inner inverted cone hole and is provided with axial grooves which are evenly distributed along the circumference; the upper part of the elastic sleeve barrel is provided with a screw thread line which can share one axial line with the inner inverted cone hole; the lower end of the outer surface of the elastic sleeve barrel is provided with a circular disc cutting edge; the main body of the sliding rod is the column shape; the lower end of the sliding rod is a column surface which can carry out the transition with the circular arc of the end surface; the upper part of the column surface is provided with outer screw thread which is matched with the screw thread hole of the elastic sleeve barrel; the upper end of the sliding rod is provided with a sliding cap, wherein, the diameter of which is bigger than the diameter of the main body of the sliding rod; a handle can be installed on the sliding cap; the sliding rod is sheathed with the weight dropper. The tool has the advantages of simple structure and easy operation. The utility model doesn't have the damage for the working surface of the oil block, and the pulled oil block can be used repeatedly.

The stifled puller of bowl type oil

The utility model relates to a kind of bowl of stifled puller of type oil, belongs to be specifically designed to the stifled hand tools of dismounting bowl type oil.

In the prior art, adopt bowl type oil stifled on many plant equipment, in order to shutoff device manufacturing process hole, or bulkhead water channel, the oil duct that need clean.But, can only carry out destructiveness and remove owing to there is not special-purpose extracting tool.Not only bowl type oil is stifled itself scraps, and also can damage equipment body, and dismounting is wasted time and energy.

The purpose of this utility model provides a kind of simple in structure, easy operating, to stifled working face of oil and the stifled puller of the undamaged bowl of equipment body type oil.

The purpose of this utility model realizes by following technical solution.

A kind of bowl of stifled puller of type oil, by resilient sleeve, slide bar, weight and handle are formed, the resilient sleeve bottom has the back taper endoporus and offers the axial groove that is uniformly distributed along the circumference, top is and back taper endoporus coaxial line and the diameter screwed hole greater than back taper endoporus maximum gauge, resilient sleeve outer surface lower end has back taper disk cutting edge, the slide bar main body is cylindrical, the lower end is excessive with the end face circular arc, diameter is smaller or equal to resilient sleeve back taper endoporus maximum gauge, the face of cylinder greater than its minimum diameter, one section external screw thread that matches with the resilient sleeve screwed hole is arranged on the face of cylinder, there is the slide bar cap of a diameter greater than the coaxial line of slide bar main diameter the upper end of slide bar, handle is installed on it, is set with the upper surface on the slide bar and is weight perpendicular to the plane of slide bar axis.

The cone angle of resilient sleeve back taper endoporus is 10～15 °, is uniformly distributed with 3～4 axial grooves along the circumference.

The upper end of resilient sleeve axial groove has the radially circular hole of axis normal in the resilient sleeve axis.

The resilient sleeve top pairing outer surface of screwed hole part is a hexagon.

Weight is the surperficial face of cylinder that is pressed with ridge design, or the corrugated surface of revolution of surperficial concave-convex surface.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Accompanying drawing is the structural representation of the stifled puller of the utility model bowl type oil.

The stifled puller of the utility model bowl type oil is simple in structure, and processing ease can be fast disassembles oil is stifled effortlessly, can increase substantially operating efficiency.Adopt the dismounting of the utility model instrument, to stifled working face of oil and the equal not damaged of equipment body, the oil of dismounting is stifled reusable, thereby can reduce production costs.
