Device for preventing glass cup from falling down

Abstract

The invention discloses a device for preventing a glass cup from falling down. The device comprises a base of a hollow structure, a groove is formed in the side wall of the upper end of the base, andthe bottom of the groove is provided with a heat conducting sheet; the lower end of the heat conducting sheet penetrates through the side wall of the lower end of the groove, one end of the heat conducting sheet located in the base is connected with an expansion block, and two first racks are disposed transversely in the base and located on the two sides of the expansion block respectively; firstconnecting rods are vertically arranged on the side walls of the upper ends of the two first racks respectively, two first sliding slots are formed in the inner wall of the upper end of the base and located above the corresponding first racks, the end, away from the corresponding first rack, of each first connecting rod is slidingly connected to the corresponding first sliding slot through a firstsliding block, and fixing plates are also vertically arranged on the inner wall of the upper end of the base and arranged away from the expansion block. By means of the principle of thermal expansionand clod contraction, airbags are inflated to clamp the glass cup to prevent the glass cup from pouring hot water to burn the skin of people.

Description

technical field [0001] The invention relates to the technical field related to life, in particular to a device for preventing a glass from tipping over. Background technique [0002] Daily life is inseparable from water, and the human body also needs to add a lot of water every day. There are many containers for drinking water, but we use the most glass cups. Glass cups refer to cups made of glass, usually made of high borosilicate glass. After being fired at a high temperature of more than 600 degrees, it is a new type of environmentally friendly teacup, which is more and more popular among people, but the glass itself is a fragile item, especially when it is in the office, due to getting up to pick up documents or An unintentional action of reaching out will always touch the glass, causing the hot water in the water glass to spill out and scald people's skin, and it is easy to cut people's hands when handling broken glasses. For this reason, we propose a preventive Glass ...
