Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the schematic diagram of stopping wheel and knob;
Fig. 2 is the schematic diagram at a visual angle of the leading truck after removing knob;
Fig. 3 is the schematic diagram at a visual angle of the leading truck after removing knob and stopping wheel.
Detailed description of the invention
A kind of helmet fastener as shown in Figure 1-Figure 3, comprise leading truck 1, the stopping wheel 2 be arranged in leading truck 1, be slidably disposed on left tooth bar 3 in leading truck 1 and right tooth bar 4, also comprise the knob 5 rotated for controlling stopping wheel 2, the body 21 that stopping wheel 2 comprises tabular and the elastic bumps assembly 22 be arranged in body 21 radial direction.
Elastic bumps assembly 22 comprises the cantilever 221 and linking arm 222 that are extended by body 21, and the free end of linking arm 222 two ends difference connecting cantilever 221 and cantilever 221 centre position, linking arm 222 and cantilever 221 coordinate formation fourth hole 24.Cantilever 221 is also provided with projection 223, projection 223 side be provided with guide part, opposite side is provided with retainer.
The end face of body 21 is provided with the foreign steamer teeth portion 23 be meshed with left tooth bar 3 and right tooth bar 4, left tooth bar 3 and right tooth bar 4 are all not at same monolateral tooth bar.Leading truck 1 comprises two pieces side plate arranged in parallel and the top board 11 and the base plate 12 that are connected two pieces side plate respectively, two pieces side plate, top board 11, first connecting plate and the second connecting plate are formed in one, base plate 12 comprises the first connecting plate be arranged on immediately below the first through hole 111 and the second connecting plate being arranged on side plate two ends, top board 11 is provided with the first through hole 111 of accommodating stopping wheel 2, the hole wall of the first through hole 111 is provided with the chaste tree thorn-like groove 112 matched with the projection 223 on elastic bumps assembly 22, base plate 12 is provided with the first projection that stopping wheel 2 is positioned, the axis of the first projection is provided with the second through hole 121.
Knob 5 is provided with the second projection 51 of driving stopping wheel 2 to rotate and carries out with the second through hole 121 the 3rd projection 52 that coordinates on the end face of stopping wheel 2, knob 5 is connected by screw with base plate 12, the axis of the 3rd projection 52 is provided with the screwed hole matched with screw, body 21 and elastic bumps assembly 22 is respectively arranged with third through-hole 211 and fourth hole 24 that accommodating second projection 51 inserts.The annular protrusion that the end of the 3rd projection 52 is positioned is provided with in second through hole 121.
Second projection 51 coordinates slip in the fourth hole 24 formed at linking arm 222 and cantilever 221, when rotating knob 5 and making the second projection 51 toward cantilever 221 1 sideway swivel, the retainer of projection 223 yearns for the distortion of its core wheel along the footpath of stopping wheel 2, then projection 223 leaves chaste tree thorn-like groove 112, and left tooth bar 3 and right tooth bar 4 are separated from each other; When knob 5 makes the second projection 51 toward linking arm 222 1 sideway swivel, the guide part of projection 223 can be level and smooth by chaste tree thorn-like groove 112, left tooth bar 3 and right tooth bar 4 close to each other; When knob 5 is fixed, stopping wheel 2 is distortion not, and the stop end of projection 223 is stuck in chaste tree thorn-like groove 112 groove, and left tooth bar 3 and right tooth bar 4 can not relative movements.
After user brings the helmet, toward linking arm 222 1 sideway swivel knob 5, left tooth bar 3 and right tooth bar 4 start close to each other and fastening head; Stop the rotation knob 5, and left tooth bar 3 and right tooth bar 4 maintain static and enter lockup state; Toward cantilever 221 1 sideway swivel knob 5, left tooth bar 3 and right tooth bar 4 separately, can take off the helmet from user's head.In whole process, user only needs rotation knob 5 to complete all operations.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, all do not depart from the utility model spirit and scope any amendment or equivalently to replace, it all should be encompassed in the scope of technical solutions of the utility model.
