Glass detection device adopting worm gear table board, threaded lock pins and natural rubber V-type pressing plates

Abstract

The invention relates to a tempered glass detection device, in particular to a glass detection device adopting a worm gear table board, threaded lock pins and natural rubber V-type pressing plates. The glass detection device comprises a testing table board and plate type racks, wherein a rack front upper pull rod, a rack front lower pull rod, a rack rear lower pull rod and a rack rear upper pull rod are arranged between the two plate type racks; table board rotating shafts are arranged on two sides of the testing table board and are rotationally fixed in a bearing support respectively; a support stop block is arranged at the rear upper part of each plate type rack and supports the rear lower plane of the testing table board; a drive worm gear is fixed on the table board rotating shaft on one side and is matched with a worm shaft, a worm support is fixed on the outer side surface of the corresponding plate type rack, and a worm cranking handle is further arranged at one end of the worm shaft; stud lock pins on two sides can enter conical stud locking holes in two sides of the testing table board to be locked and positioned; coplanar V-type slot pressing plate assemblies are fixed on the upper surface of the testing table board, and a broken glass recovery container is fixed on a rack front middle pull rod, the rack front upper pull rod and the rack rear upper pull rod.

Description

technical field [0001] The invention relates to a tempered glass detection device, classification number: G01N3 / 32, especially relates to such a pressure plate that can be enlarged or reduced around, and uses a reversible worktable to test the strength of the glass. type platen glass detection device. Background technique [0002] With the development of economy, the application of glass in all walks of life is more and more extensive. 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 certificatio...

Problems solved by technology

This method is not only inconvenient to operate, it takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove the broken glass, otherwise , the remaining glass fragments will affect the next experimental test operation

[0005] 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

[0006] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting frame box is adopted, although it can effectively remove glass fragments, it is inconvenient to read glass fragments , and the installation efficiency of continuous multi-piece tempered glass is low

[0007] China's other patent application number: 201420595067.X, tempered glass shard state test device, proposed some new methods and measures to deal with the pressure plate of brittle glass, but it is still impossible to adjust the size at will, and it is impossible to make the four sides of the pressure plate all in the same on flat surface

At least one side of the patent must not be in contact with the test bench surface

What is referred to as the suspended retaining wall 5 in the embodiment cannot be in contact with the base 1 simultaneously with other three-sided retaining walls, so the retaining piece 4 has to be used to make up the gap between the suspended retaining wall 5 and the base 1, resulting in four Uneven surrounding force

In addition, the width of the baffle 4 itself is fixed, and only multi-piece splicing can be used, and continuous changes of different widths cannot be achieved.
