Abstract

The invention relates to a device for detecting the knocking resistance, in particular to a device for detecting the knocking resistance of a safety helmet. The technical problem to be solved by the invention is to provide the device for detecting the knocking resistance of the safety helmet, which simplifies the operation process, reduces the labor intensity of workers and improves the working efficiency. In order to solve the technical problem, the device for detecting the knocking resistance of the safety helmet comprises a bottom plate, a limiting frame, a power mechanism, a conveying mechanism and a testing mechanism, wherein one side of the top of the bottom plate is connected with a supporting block; the limiting frame is connected to the supporting block; the power mechanism is connected to one side of the top of the bottom plate; the conveying mechanism is connected between the bottom plate and the supporting block; and the testing mechanism is connected to two sides of the supporting block. Through cooperation of the power mechanism, the conveying mechanism and the testing mechanism, knocking work can be completed without walking back and forth of workers, the labor amount of the workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a device for knock resistance, in particular to a device for detecting the knock resistance of a safety helmet. Background technique [0002] A safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. The safety helmet consists of a cap shell, a cap lining, a chin strap and accessories. [0003] Safety helmets will go through a series of safety inspections before they leave the factory. The percussion inspection of safety helmets is usually carried out by workers in the same batch of products for sampling inspection. In order to detect the knock-resistant function of the safety helmet, the above-mentioned operation process is relatively complicated, the labor intensity of the workers is high, and the work efficiency is low. [0004] Therefore urgently need to develop a kind of device that simplifies the operation process, alleviates the worker's labor inten...
