In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of novel simple resetting structure of castor, comprise the brake pedal be hinged on foot wheel carrier, the articulated jib bottom of described brake pedal has the brake tooth in order to engage with castor internal tooth, described foot wheel carrier is provided with from lock set above described articulated jib, described articulated jib medial extremity is hinged with reed, described reed is provided with in order to supporting spring and as the limit body of reed centre of gration between its free end and pin jointed end, be provided with above the free end of described reed to rotate with movable contact spring with the reset assembly removing self-locking.
Preferably, described reset assembly comprises push rod, and described foot wheel carrier offers the through hole hanging push rod above reed free end, and described push rod is arranged with retracing spring, and described push rod is along through hole up-and-down movement and be with movable contact spring to rotate around limit body.
Preferably, describedly comprise self-locking block from lock set, described self-locking block bottom is provided with arc groove, and described articulated jib upper end has the projection matched with arc groove, is provided with the self-locking spring in order to be pressed on by self-locking block on articulated jib above described self-locking block.
Preferably, described foot wheel carrier offers the notch limiting brake pedal above the projecting end of described brake pedal.
Compared with prior art, the utility model has following beneficial effect: the utility model reasonable in design, compact, utilizes mechanical self-latching to brake dexterously, lever rule is utilized to carry out brake off, convenient to use, be easy to promote, there is higher practicality and applicability.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Fig. 1 ~ 4, a kind of novel simple resetting structure of castor, comprise the brake pedal 2 be hinged on foot wheel carrier 1, articulated jib 21 bottom of described brake pedal 2 has the brake tooth 23 in order to engage with the internal tooth 31 of castor 3, described foot wheel carrier 1 is provided with from lock set 4 above described articulated jib 21, described articulated jib 21 medial extremity is hinged with reed 5, described reed 5 is provided with in order to supporting spring 5 and as the limit body 6 of reed 5 centre of gration between its free end 51 and pin jointed end 52, the reset assembly 7 rotating to remove self-locking with movable contact spring 5 is provided with above the free end 51 of described reed 5.
In the utility model embodiment, described reset assembly 7 comprises push rod 71, described foot wheel carrier 1 offers the through hole 11 hanging push rod 71 above reed 5 free end 51, described push rod 71 is arranged with retracing spring 72, and described push rod 71 is along through hole 11 up-and-down movement and be with movable contact spring 5 to rotate around limit body 6.
In the utility model embodiment, describedly comprise self-locking block 41 from lock set 4, described self-locking block 41 bottom is provided with arc groove 411, described articulated jib 21 upper end has the projection 211 matched with arc groove 411, is provided with the self-locking spring 42 in order to be pressed on by self-locking block 41 on articulated jib 21 above described self-locking block 41.
In the utility model embodiment, described foot wheel carrier 1 offers the notch 12 limiting brake pedal 2 above the projecting end 22 of described brake pedal 2.
Concrete use procedure of the present utility model is as follows: when needing to brake castor 3, step on brake pedal 2, the articulated jib 21 of described brake pedal 2 moves around hinge-point, the elastic force that the projection 211 of described articulated jib 21 overcomes self-locking spring 42 slides to arc groove 411, unclamps described brake pedal 2, under the effect of the elastic force of described self-locking spring 42, described articulated jib 21 is compacted, realize castor 3 to brake, now, the free end 51 of described reed 5 is higher than pin jointed end 52; When needing castor 3 brake off, pressure push rod 71, the free end 51 that described push rod 71 overcomes the elastic band movable contact spring 5 of retracing spring 72 moves downward, according to lever rule, pin jointed end 52 upward movement of described reed 5, drive the articulated jib 21 of brake pedal 2, projecting end 22 all upward movements, the projection 211 of described articulated jib 21 skids off the arc groove 411 of self-locking block 41, removes castor 3 and brakes.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw the novel simple resetting structure of other various forms of castors under enlightenment of the present utility model.All equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
