Inclined-plane turn angle arbitrary four-side engineering rubber fixing rest pliers

Abstract

The invention relates to fixing rest pliers for glass detection, and in particular relates to a pair of inclined-plane turn angle arbitrary four-side engineering rubber fixing rest pliers. The pair of inclined-plane turn angle arbitrary four-side engineering rubber fixing rest pliers has following improvement: one end of an upper clamping plane is provided with an inclined-plane groove the bottom surface of which is provided with a bottom plane of the groove; the cross section of the inclined-plane groove is isosceles trapezoid; a lower slipping plane is provided with a rotary through hole; a rotary plate chamber arc surface is arranged at one side of the rotary through hole; the turn angle chamber arc surface is provided with a turn angle arc surface protruding pointer; an inclined-plane convex rail is positioned on the lower slipping plane; the cross section of the inclined-plane convex rail is also isosceles trapezoid; the lower slipping plane is provided with two plane screw holes; the inclined-angle convex rail is also provided with two convex rail stepped holes; convex rail screws pass through the convex rail stepped holes and are fit with the plane screw holes in a spirally fastening mode so as to fix the convex rail contact surface on the lower slipping plane; inclined planes at two sides of anti-falling raised lines and inclined planes at two sides of anti-falling grooves are in interference fit so as to generate extrusion and expansion force and prevent falling accidents caused by glue aging; heights of the anti-falling raised lines and depths of the anti-falling grooves are in clearance fit for the convenience of installation and binding.

Description

technical field [0001] The invention relates to a fixed clamp for glass detection, in particular to such an engineering rubber fixed clamp with any four sides of an inclined plane corner that can be enlarged or reduced around and used for testing the strength of glass. Background technique [0002] Glass is one of the oldest materials discovered and utilized by man. As early as 3,500 years ago, ancient Egypt had the technology of making simple glass objects, and in the tombs of the Western Zhou Dynasty in my country, man-made glass ornaments were also unearthed. With the development of science and technology, glass has developed particularly rapidly in the past one hundred years, and glass has become an indispensable material in human daily life. With the development of economy, the application of glass in all walks of life is more and more extensive. Glass can be used as glass curtain walls, glass doors and windows, etc. in buildings, as teacups, wine bottles, lamps, et...

AI Technical Summary

Problems solved by technology

Due to the diversity of automobile designs, the glass on the corresponding car is becoming more and more complex. The shape of the glass is often not square or rectangular, but parallelogram or trapezoidal. Uniform fixation clamps can only use scotch tape or other methods to restrain the periphery of the glass, or cover a layer of film on the tempered glass to prevent glass fragments from splashing

At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device
