Description

Quick-release device applied to safety helmet

Technical Field

The utility model relates to the technical field of safety helmets, in particular to a quick-release device applied to a safety helmet.

Background

The safety helmet is a hat which has the function of protecting the head from being hurt by falling objects and other specific factors and consists of a helmet shell, a helmet liner, a chin strap, accessories and the like; the cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the hit object are mainly borne by the cap shell.

With the development of the times and the progress of science and technology, the traditional safety helmet only having the function of protecting the head cannot meet the current requirements, so that the intelligent safety helmet integrating the functions of camera shooting and the like appears. However, the traditional intelligent safety helmet adopts an integrated structure, the damage often occurs due to the limited use scene of the safety helmet, the damaged place is usually only a helmet shell, and other intelligent modules are still intact, but the integrated structure cannot directly detach each intelligent module to replace the intelligent module to a new helmet shell, so that the whole intelligent safety helmet needs to be purchased again, and the use cost of the safety helmet is high.

Therefore, how to provide a quick release device applied to a safety helmet, which realizes quick detachment of the safety helmet and reduces the use cost becomes a problem to be solved urgently.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a quick-release device applied to a safety helmet, so that the quick disassembly and assembly of the safety helmet are realized, and the use cost is reduced.

The utility model is realized by the following steps: a quick release device applied to a safety helmet, comprising:

the side of the shell is provided with at least two clamping grooves and at least three fixing holes;

the at least two fixing mechanisms are arranged in the shell and extend and retract in the fixing holes;

the fixing mechanism includes:

the two springs are arranged inside the shell, and one end of each spring is fixedly connected with the shell;

and one side of the fixing part is provided with three convex blocks side by side, one side of the fixing part is fixedly connected with the spring, and the other side of the fixing part penetrates through the fixing hole through the convex blocks.

Further, when the spring is in a non-compressed state, the lug extends out of the fixing hole for a certain distance; when the spring is in a compressed state, the lug does not extend out of the fixing hole.

The utility model has the advantages that:

the shell is provided with the fixing mechanism comprising the spring and the fixing piece, the side edge of the shell is provided with the clamping groove and the fixing hole, primary positioning is carried out through the clamping groove and the buckle arranged on the intelligent safety helmet, and secondary fixing is further carried out through the fixing mechanism and the fixing groove arranged on the intelligent safety helmet; when the quick-release device is mounted on the intelligent safety helmet, the fixing piece automatically extends into the fixing groove under the action of the elastic force of the spring to complete fixing; because the fixed slot is hollow out construction, when needs are dismantled, only need press one of them lug and compression spring from the one end of fretwork, carry to safety helmet vertical direction one gently, can let buckle and draw-in groove separation, accomplish quick detach device's dismantlement, and the inside camera that can load of casing, a battery, parts such as MCU, the quick assembly disassembly of intelligent safety helmet is finally realized, be convenient for change when certain part damages, needn't purchase whole intelligent safety helmet again, and then very big reduction intelligent safety helmet's use cost.
