Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is clearly and completely retouched
State, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on this
Embodiment in utility model, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of this utility model protection.
As it is shown in figure 1, the chin positioning lock of the helmet of the present embodiment, including pedestal 4, rotating seat 3 and lock dog 5.On pedestal 4
It is machined with groove 42, groove 41, gathering sill 44 and susceptor through-holes 43, groove 42 and groove 41 all in circular arc, gathering sill
44 connect with groove 41.Chimb 32, boss 31 and rotating seat through hole 33, chimb 32 and groove 42 it is machined with on rotating seat 3
Matching, boss 31 matches with groove 41.Screw is each passed through susceptor through-holes 43 and rotating seat through hole 33, thus by rotating seat 3
Being installed on pedestal 4, now chimb 32 matches with groove 42, and boss 31 matches with groove 41, and rotating seat 3 is at base
Seat 4 on rotatable.Lock dog 5 is elongated, and the gathering sill 44 of its described pedestal 4 of loading is interior and can move in gathering sill 44.
Lock dog 5 two ends are machined with the first limited block 51 and the second limited block for limiting the lock dog 5 position in gathering sill 44 respectively
52, on lock dog 5, between the first limited block 51 and the second limited block 52, place is machined with elastic edge 53, and this elastic edge 53 is processed
There is edge 54, pedestal 4 is machined with in gathering sill 44 projection 45 for stopping edge 54.
Below the operation principle of chin positioning lock described in the utility model is described in further detail.
With reference to Fig. 4, chin positioning lock is installed on the helmet, and wherein pedestal 4 is installed in helmet main body 1, and rotating seat 3 is installed
On chin 2.With reference to Fig. 2, lock dog 5 is not inserted in the groove 41 of pedestal 4, and now chin 2 is not locked and can overturn.
When chin 2 needs after rolling up to lock chin 2, lock dog 5 is pushed in the groove 41 of pedestal 4, in push-on process, elastic edge
53 elastic deformations, edge 54 crosses the projection 45 of pedestal 4, more after the projection 45 of pedestal 4 stop edge 54, lock dog 5
Being fixed and stop the boss 31 of rotating seat 3, now chin 2 is locked against falling down.When chin 2 being turned down,
By lock dog 5 pushed home, chin 2 now can be turned down.
Chin positioning lock of the present utility model, it is installed on the helmet, can realize lock with this chin positioning lock after chin rolls up
Fix bar, thus prevent chin from dropping in the process of moving and affect normal driving, thus improve travel safety.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all new in this practicality
Within the spirit of type and principle, any modification, equivalent substitution and improvement etc. made, should be included in protection of the present utility model
Within the scope of.
