The specific embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Provided preferred embodiment of the present utility model in accompanying drawing.But the utility model can be realized in many different forms, is not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present utility model more comprehensively thorough.
As shown in Figure 1, its perspective view that is the draw-bar box 10 in an embodiment.Draw-bar box 10 comprises: the pull bar 12 at casing 11, extended casing 11 tops, be installed on casing 11 bottoms wheel group structure 13, be installed on controller 14 on casing 11, be installed on casing 11 and cotton rope 15 that two ends are connected with controller 14 with wheel group structure 13 respectively.Controller 14 is controlled wheel group structure 13 by cotton rope 15, makes wheel group structure 13 brakings and removes braking.
As shown in Figures 2 and 3, perspective view and the cross-sectional view of its wheel group structure 13 that is the draw-bar box 10 shown in Fig. 1.Wheel group structure 13 comprises: wheel 100, wheel seat 210, wheel support 220, detent 300 and driving section 400.
As shown in Figure 4, the STRUCTURE DECOMPOSITION figure of its detent 300 that is the wheel group structure 10 shown in Fig. 3.Detent 300 comprises: drive rod 310, two brake members 320 and two elastic components 330.
Brake member 320 is installed on wheel support 220 slidably, and glide direction is parallel with the axis direction of rotating shaft 101.The other end that one end of two brake members 320 is provided with respectively second voussoir 321, two brake members 320 corresponding with two the first voussoirs 312 is provided with respectively the projection 323 corresponding with pit 103 on double the wheel.The mutual butt of wedge surface of the second voussoir 321 and the first voussoir 312.In the present embodiment, two relative drive rods 310 of brake member 320 are symmetrical arranged.
Two elastic components 330 lay respectively between two brake members 320 and wheel support 220, and 330 whiles and brake member 320 and wheel support 220 butts of elastic component.In the present embodiment, two relative drive rods 310 of elastic component 330 are symmetrical arranged.Elastic component 330 is for providing elastic-restoring force in brake member 320, it can be resetted.In the present embodiment, elastic component 330 is spring.
As shown in Figure 5, Figure 6, it is respectively cross-sectional view and the perspective view of the wheel group structure 13 of wheel 100 in free rotary state.From scheming, can see, projection 323 breaks away from pit 103, and wheel 100 is not subject to the constraint of brake member 320, can freely rotate.
As shown in Figure 7, Figure 8, it is respectively cross-sectional view and the perspective view of the wheel group structure 13 of wheel 100 in on-position.While needing braking, pull cotton rope 15 by controller 14, cotton rope 15 drives driving section 400 toward the motion of the direction away from wheel 100, driving section 400 drives drive rod 310 motions, the second voussoir 321 on the first voussoir 312 drive brake members 320 on drive rod 310 moves along the axial direction of rotating shaft 101, projection 323 on brake member 320 is contained in pit 103, and wheel 100 is braked.
When needs are cancelled the braking of wheel 100, control by 14 pairs of cotton ropes 15 of controller, make cotton rope 15 shrink, be provided with back-moving spring in driving section 400, back-moving spring makes the drive rod 310 be connected with driving section 400 reset, brake member 320 resets under the effect of elastic component 330 simultaneously, and projection 323 breaks away from pit 103, and the braking of wheel 100 is disengaged.
While draw-bar box 10 being placed on the vehicles such as bus, because wheel 100 can be braked, draw-bar box 10 can not move freely due to the effect of inertia of the vehicles, to people's trip, has brought convenience.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
