Abstract
The utility model discloses a detachable lower jaw structure of a safety helmet, which comprises a lower jaw and lower jaw switches, wherein the lower jaw and a helmet shell are directly connected via the lower jaw switches so as to form a detachable helmet body jaw protection device. Ear cover assemblies are arranged on two sides of the helmet shell, and are connected with the lower jaw via the lower jaw switches so as to form the detachable helmet body jaw protection device; each ear cover assembly has a chamber for accommodating one lower jaw switch; both sides of the lower jaw extend into the chambers and are buckled with the lower jaw switches. The detachable lower jaw structure disclosed by the utility model can be directly connected with the helmet shell, or can be detachable as the ear covers, and belongs to the scope of protection. The lower jaw and the ear cover assemblies are buckled via the lower jaw switches, and the ear cover assemblies are also connected with the helmet shell. The lower switches are firstly disconnected from the lower jaw and then push the lower jaw to move forwards so as to enable the lower jaw to be detached from the helmet shell conveniently. Therefore, the detachable lower jaw structure has the advantages of convenience for assembling and disassembling, environment protection and the like.
Description
Technical field
The utility model discloses the detachable lower jaw structure of a kind of safety cap, divides by International Patent Classification (IPC) (IPC) to belong to the safety cap technical field, especially relates to the safety cap of a kind of cap shell and lower jaw easy disassembly.
Background technology
Safety cap all should wear to protect head also referred to as the helmet such as the driver or the roller skating person that drive motorcycle, electric motor car etc.In existing safety cap; the chin of cap body or lower jaw baffle are for the protection of cyclist's chin; its both sides are fixed on the both sides of helmet body; throw off with the helmet preventing; for example consist of holistic full helmet with the cap body; each parts are completed assembling by glue or screw, and especially adhesion process, easily cause environmental pollution, not environmental protection.
But China document CN201220027913.9 relates to a kind of helmet of fast dismantling chin, and the detachable lower jaw structure left and right sides has catching groove and is articulated in the tightening up on catch of helmet body two inboards; And document CN201020554013.0 easy-to-dismount Combined helmet, this Combined helmet comprises housing and protect bar, and both link together by structure easy to assemble, and structure easy to assemble comprises tongue and the slot that mutual kayser coordinates.Although above-mentioned two schemes can realize the combination of lower jaw structure and helmet body, the disassembly and assembly structure more complicated, and need the user do not drive or motion process in just can complete aforesaid operations, use inconvenient.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of safety cap rational in infrastructure detachable lower jaw structure.
For achieving the above object, the utility model is achieved through the following technical solutions:
The detachable lower jaw structure of a kind of safety cap, it comprises lower jaw and lower jaw switch, lower jaw is connected with the cap shell by the lower jaw switch and consists of dismountable cap body and protect the jaw device.
Further, described cap shell both sides are provided with the ear cap assemblies, and lower jaw and lower jaw switch are connected on the cap shell by the ear cap assemblies.
Further, described ear cap assemblies has a casket chamber and is used for accommodating lower jaw switch, and the both sides of lower jaw extend in above-mentioned casket chamber and are connected with the lower jaw switch latch.
Further, described casket chamber has vertical guide groove and horizontal guide groove, be provided with in vertical guide groove wherein that the lower jaw switch can move up and down and the hook pin of lower jaw switch extend in horizontal guide groove with the hook section snap close of lower jaw and is connected, the lower jaw switch is connected so that this switch is in the jack-up state with a spring element.
Further, described lower jaw switch forms with the lower jaw contact-making surface disengaging inclined-plane that matches, the lower jaw switch moves down along vertical guide groove, after the hook section of its hook pin and lower jaw threads off, the lower jaw switch continues to move down, it is that lower jaw switch promotion lower jaw outwards slides along horizontal guide groove that above-mentioned disengaging inclined-plane interacts, thereby the ear lid that lower jaw is connected with the cap shell separates certain distance, facilitates the user to dismantle lower jaw in the process of riding.
Further, described ear cap assemblies is to comprise ear lid and ear cover panel, and both are assembled into one in cooperation.
The detachable lower jaw structure of the utility model can be directly with the cap shell joint close or as the ear lid be removable be all protection domain; a kind of mode is by the lower jaw switch, lower jaw and ear cap assemblies to be linked; and the ear cap assemblies is connected with the cap shell; first thread off and then lower jaw is promoted forward due to lower jaw switch and lower jaw, make and the dismounting of cap shell convenient separation, easy to assembly, the effect that reaches environmental protection.
