Description

Improve the combined type helmet of structure

Technical field

The utility model relates to a kind of helmet, belongs to motorcycle safety equipment field, refers in particular to a kind of combined type helmet that improves structure.

Background technology

Motorcycle helmet as a kind of safety means of protecting head, is that each motorcycle driver and occupant must carry in driving procedure.Traditional motorcycle helmet is divided into half helmet helmet and two kinds on full helmet helmet, in cities and towns, China south, because the time in summer is long, the temperature height, high humidity, generally only carry half helmet helmet in the motorcycle driving procedure, and winter temperature is low, wind speed must carry full helmet helmet greatly again in the motorcycle driving procedure, particularly in scorch or motorcycle competitive sport, to carry full helmet especially, thereby, cause the motorcycle driver will prepare two kinds of helmets, very be inconvenience.

So, beginning to occur a class combined type helmet afterwards on the market, this class helmet is provided with the housing that is rotationally connected and protects crust, when protecting crust commentaries on classics formation when getting on half helmet helmet, then forms full helmet helmet when changeing protecting crust, and is simple and convenient.At present, the housing of this class combined type helmet and protect crust and generally directly couple together by rotating shaft is not provided with any latching device, so when wind speed greatly or during scorch, protect crust and be easy to generate and rock, thereby may cause interference, influence safe driving the driver with housing.

The utility model content

The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of combined type helmet with improvement structure of latching device is provided.

To achieve these goals, the utility model is realized by following technical scheme:

A kind of combined type helmet that improves structure comprises housing and protects crust that both are rotationally connected; Described housing both sides are provided with to control to protect with the correspondence position that protects crust clings to the latching device that forms full helmet or half helmet with housing activity snap fit.

Further, described latching device comprises :-movable lock hook assembly, be fixedly arranged on that to protect crust inboard, it comprises the latch hook that cooperates with following latch hook cover snap close, the shift knob that moves by steel wire rope control latch hook and the hold-down support that is used to install and fix latch hook and shift knob;-latch hook cover is fixedly arranged on the housing, which is provided with the lock hook slot that inserts locking for above-mentioned latch hook.

Further, described latch hook one end is and the hook portion of lock hook slot activity snap fit that the opposite end is the connecting portion that is rotationally connected with hold-down support.

Further, described latch hook hook portion outer face is a circular arc guiding transition face.

Further, described shift knob is flush-mounted in the hold-down support, and it is in transmission connection by steel wire rope and latch hook.

Further, the press surface of described shift knob is towards housing, and it is subjected to force direction to protect the crust outside from protecting the interior side direction of crust.

Further, described hold-down support by screw with protect that crust is inboard fixedlys connected, which is provided with: a mount pad is used to install latch hook and is rotationally connected with it and cooperates; One mounting groove is used to install shift knob; One back-moving spring, its two spring leaf contacts cooperation with latch hook respectively with hold-down support, make it be tending towards cooperating with latch hook cover snap close for latch hook provides reseting elasticity.

Further, described hold-down support is provided with the guide groove that holds steel wire rope.

Further, described latch hook is placed in the lock hook slot top and is set to smooth guiding surface.

The utility model compared with prior art, its beneficial effect is: in the housing both sides with protect the crust correspondence position and be provided with latching device, housing and protect crust can effectively lock when forming full helmet, increase the safe driving coefficient, simultaneously, overall structure is simple, cost is low, and assembling and operation are all convenient and swift.

In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
