Description

Helmet glasses lens face shield mount pad

Technical field

The utility model relates to the structure, particularly lens mounting stand that the helmet is connected with the face shield assembling.

Background technology

Traditional helmet is connected simple axis hole articulated structure with the eyeglass face shield, hinge and face shield, the helmet all are movably hinged.The hinge end is spacing by nut, and such assembly structure is simple, but frequent owing to vibrating in the use, stop nut very easily gets loose, and causes face shield to lose efficacy.On the other hand, the mechanism that regulates the face shield subtended angle generally is located at face shield rear portion hinge side, and what have directly is processed into profile of tooth and cooperates with profile of tooth on the securing member and regulate subtended angle with reaming.Because stress is concentrated, profile of tooth is worn and torn easily, dislocation and latch, make the face shield subtended angle regulate inconvenient, service life is short.Chinese patent 00209130.5 once improved the problems referred to above, but owing to need use tiny members such as lock hook, following lock hook, spring groove, cooperated between each member and easily go wrong, and manipulated trouble.On the basis of Chinese patent 00209130.5, Chinese patent 00245461.0 adopts the locking key structure more further with designs simplification, but still exists locking insecure, and the possibility of deviating to unclamp is arranged, defectives such as elastic force deficiency, and practical effect is undesirable.

The utility model content

The utility model is at the deficiency of prior art, specially proposes a kind of improved helmet glasses lens face shield mount pad, makes between the face shield and the helmet fitting operation simple, easily, lock solid and reliable, anti-loose, long service life.

The technical solution of the utility model is: helmet glasses lens face shield mount pad, be connected between helmet body and the eyeglass face shield, allow the eyeglass face shield can do the certain angle swing, its seat board is flat, seat board is provided with the elastic claw sheet with face shield tooth bar engagement, is provided with the ring shaft base that cooperates with the face shield dead axle, is provided with to lead with face shield to collude the guide groove that is slidingly matched, guide groove is arranged in the periphery of elastic claw sheet, and guide groove top has to lead with face shield and colludes corresponding breach; But the lock hook of an elastic reset then is housed on the seat board, the end of lock hook just in time with guide groove on the complementary snapping of breach.Further, the breach on guide groove top can import and collude, and will lead to collude being locked in the guide groove behind the end of lock hook and the breach snapping.And lock hook is articulated on the seat board, and reduction torsion spring is housed on the hinge.

Such structure, its advantage is:

1, adopts lock hook that face shield is led to collude and lock, cooperate the directional lock of face shield dead axle and ring shaft base, make the mounting or dismounting operation of eyeglass face shield and helmet body very simple easily;

2, lock hook and leading colludes, dead axle and axle bed form the two dimension locking respectively, locks solid and reliablely, is difficult for getting loose;

3, the adjusting of eyeglass face shield subtended angle is freely suitable, and stress is concentrated little, long service life.

The specific embodiment

Referring to Fig. 1-Fig. 5, the seat board 1 of present embodiment is flat, have fraising 11 on it with 2 assemblings of eyeglass face shield, on fraising 11 excircles, be provided with directed annular axle bed 12, dead axle 21 rotations on directed annular axle bed 12 and the face shield 2 cooperate, the periphery of directed annular axle bed 12 is provided with the elastic claw sheet 13 with 22 engagements of face shield tooth bar, the periphery of elastic claw sheet 13 is provided with to lead with face shield colludes 23 guide grooves that are slidingly matched 14, guide groove 14 tops have breach 15, the size of breach 15 and face shield lead collude 23 corresponding, face shield is led and is colluded 23 and can import in the guide grooves 14 along breach 15 during assembly, and meanwhile, the periphery of guide groove 14 is hinged with a lock hook 3, the end of lock hook 3 just in time with guide groove 14 on breach 15 complementary snappings, torsion spring 4 also is housed on the hinge of lock hook 3, can automatically resets after lock hook 3 is opened, lock hook 3 ends are with breach 15 shutoff under the normality.

Assembling process is such: dead axle 21 directed the importings in the ring shaft base 12 that allow face shield, simultaneously, face

shield tooth bar

22 and 13 interlocks of elastic claw sheet, adjust the angle of eyeglass face shield 2, face shield is led collude 23 over against breach 15, firmly push eyeglass face shield 2 then, lock hook 24 ends are flicked, face shield is led and is colluded 23 from breach 15 importing guide grooves 14 (as shown in Figure 3), after flicking, lock hook 3 automatically resets, again with breach 15 sealing, thereby with dead axle 21, the tooth bar 22 of face shield, lead and collude 23 lockings, face shield 2 can only be rotated, to regulate the subtended angle of eyeglass face shield along guide groove 14, elastic claw sheet 13.As will dismantling eyeglass face shield 2, need only collude 23 and go to outside the breach 15 leading, press lock hook 3, breach 15 is opened, firmly will lead and collude 23 and pull out along breach 15, face shield dead axle 21 gets loose from ring shaft base 12 simultaneously, just face shield can be taken off.

Claims

1, helmet glasses lens face shield mount pad, be connected between helmet body and the eyeglass face shield, allow the eyeglass face shield can do the certain angle swing, its seat board is flat, seat board is provided with the elastic claw sheet with face shield tooth bar engagement, is provided with the ring shaft base that cooperates with the face shield dead axle, is provided with to lead with face shield to collude the guide groove that is slidingly matched, it is characterized in that: guide groove is arranged in the periphery of elastic claw sheet, and guide groove top has to lead with face shield and colludes corresponding breach; But the lock hook of an elastic reset then is housed on the seat board, the end of lock hook just in time with guide groove on the complementary snapping of breach.
