Stair corner free quadrilateral natural rubber fixing pressing plate

Abstract

The invention relates to a fixing pressing plate for glass detection and a stair corner free quadrilateral natural rubber fixing pressing plate. The stair corner free quadrilateral natural rubber fixing pressing plate comprises a first clamping plate, a second clamping plate, a third clamping plate and a fourth clamping plate, all of which are the same in structural size. Each clamping plate is composed of a clamping part and a sliding corner part. The stair corner free quadrilateral natural rubber fixing pressing plate is characterized in that each lower sliding plane is provided with a rotating through hole, a rotary table chamfer cambered surface is arranged on the other side of each rotating through hole, and each rotary table chamfer cambered surface is provided with a corner cambered surface protruding pointer, a stair groove is formed in the other side of each rotating through hole, an arch cambered surface is arranged on the back face of each stair groove position, a transition groove is formed between each stair groove and the corresponding lower sliding plane, and the two ends of the stair groove are open; a stair protruding rail is arranged at one end of each upper clamping plane, and each upper clamping plane and a corresponding transition protruding rail are separable; each protruding rail screw penetrates through a corresponding protruding rail stepped hole, each protruding rail screw and a corresponding plane screw hole are in a spiral immovable fitting mode, each protruding rail contact face is fixed to the corresponding upper clamping plane, and continuous and free adjustment can be achieved for trapezoidal glass plates with different widths.

Description

technical field [0001] The invention relates to a fixed platen for glass detection, in particular to such a natural rubber fixed platen with any four sides of a stepped corner that can be enlarged or reduced in four directions and used for testing the strength of glass. Background technique [0002] At present, many important glass components, such as large-scale glass curtain walls and glass zeniths, and windshield glass of aerospace vehicles are made of special glass such as toughened glass, which has very strict requirements on glass performance, so it is becoming more and more important to test the performance of glass . Since May 1, 2003, my country has implemented a mandatory inspection system for safety glass used in automobiles, trains, and buildings. Safety glass products that have not obtained a compulsory product certification certificate and have not been marked with China Compulsory Product Certification are not allowed to leave the factory. import and sale. ...

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 glass can be found everywhere. In the past, there was no detection of this kind of irregular quadrilateral glass. Unified fixed pressure plate, only use scotch tape or other methods to restrain the glass perimeter, 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
