Glass clamp

Abstract

The invention discloses a glass clamp. The glass clamp comprises a clamp main body which is provided with a clamping groove used for clamping glass, and a hanging assembly which is positioned at the top of the clamp main body and is used for connecting an external structure; the clamp main body comprises a front glass clamp and a rear glass clamp which are connected with each other and define the clamping groove, and a connecting piece which is used for fixing the front glass clamp and the rear glass clamp; a first rack and a second rack are respectively arranged on the opposite sides of the front glass clamp and the rear glass clamp, and the first rack and the second rack are in vertical engagement connection. In the scheme of the invention, the first rack and the second rack are fastened and buckled by locking a glass connecting piece, so that the purpose of clamping the glass is achieved; a hole does not require to be formed in the glass, so that the original internal stress balance of the glass is prevented from being disturbed; moreover, a limiting effect is achieved through a tooth engagement structure, and the situation that the glass is broken because of stress concentration caused by overexerting when screw threads of the glass clamp are locked is prevented.

Description

technical field [0001] The invention relates to the field of door and window hardware, in particular to a glass fixture. Background technique [0002] Because the frameless glass door has the advantages of good light transmission performance and beautiful appearance, it is widely welcomed in places such as residences, shopping malls, and office buildings. However, because glass is very brittle, has low fracture toughness, and does not have the ability to distribute loads and absorb impact energy, glass is very sensitive to stress concentration. The force of the point-supported glass hole is quite complicated, and it is the weak link of the whole piece of glass. Therefore, under the load condition, once the defective glass exceeds its critical stress, the glass will shatter. [0003] The main feature of the hole-free glass clamps on the market today is that there is no need to open the upper slot, and two round holes need to be opened in the middle to add load-bearing pins t...

AI Technical Summary

Problems solved by technology

However, due to the high brittleness of glass, low fracture toughness, and the ability to distribute load and absorb impact energy, glass is very sensitive to stress concentration.

The force of the point-supported glass hole is quite complicated, and it is the weak link of the whole piece of glass. Therefore, under the load condition, once the defective glass exceeds its critical stress, the glass will shatter

[0003] The main feature of the hole-free glass clamps on the market today is that there is no need to open the upper slot, and two round holes need to be opened in the middle to add load-bearing pins to achieve load-bearing. The glass is clamped by locking screws and threads, and there is no limit function. , Excessive force will cause glass stress concentration, resulting in glass breakage, resulting in injury incidents
