Abstract
The invention provides a universal wheel with a brake function. The universal wheel with the brake function has a simple structure and a self-locking insurance function, and can be convenient to relieve the insurance function. The universal wheel with the brake function comprises a support, a bracket and an roll wheel; the support is connected with the roll wheel by the bracket; star-shaped locking teeth are arranged on the center axle of the roll wheel; a braking pedal is hinged on the bracket; locking lugs are arranged on the braking pedal; the locking lugs can be matched with the star-shaped locking teeth of the roll wheel; a locating lug is arranged on the braking pedal; a limiting lug is arranged on the bracket; the locating lug and the limiting lug correspond and can perform back-front double-way clamping and matching; and at least one of the two matching surfaces is an inclined transition plane when the back-front double-way clamping and matching is performed.
Description
Technical field
The present invention relates to a kind of cardan wheel of belt brake, particularly relating to can the cardan wheel of belt brake of self-locking safety.
Background technology
The cardan wheel of existing belt brake, adopt brake facing or star-like lock tooth to coordinate lock projection and locking mode mostly, but these locking structures are not with self-locking safety function, at unidirectional locking, oppositely then easily can only unclamp, make locking effect bad, and the brake cardan wheel of other band insurance function relies on the insurance function mechanism increased again in addition to realize, this structure is comparatively complicated, and needs manually opened insurance to remove locking after secure ratch, troublesome poeration.
Summary of the invention
The object of this invention is to provide a kind of structure simple, can self-locking safety, and the cardan wheel of the belt brake of arming function can be facilitated.
For achieving the above object, the technology of the present invention solution is such: a kind of cardan wheel of belt brake, comprise holder, support, roller, holder is connected with roller by support, described roller center shaft is provided with star-like lock tooth, described support is hinged with brake pedal, brake pedal is provided with lock projection, described lock projection can match with the star-like lock tooth of roller, brake pedal is provided with locating convex block, described support is provided with spacing block set, described locating convex block is corresponding with spacing block set position and can two-way snap-fit engagement back and forth, one is had at least for intermediate incline in two fitting surfaces when two-way clamping back and forth.
Due in above-mentioned technical solution, roller center shaft is provided with star-like lock tooth and brake pedal and is provided with and locks projection and match, the locking of cardan wheel can be realized, and brake pedal is provided with locating convex block, described support is provided with spacing block set, described locating convex block is corresponding with spacing block set position and can two-way snap-fit engagement back and forth, and have one in two fitting surfaces when two-way clamping back and forth at least for intermediate incline, therefore during releasing orientation spacing block set upper locating convex block under, when not using external force to step on brake pedal, snap-fit engagement between spacing block set and locating convex block can keep releasing orientation, the lock projection of brake pedal can not be made to enter the star-like lock tooth of roller, and when needs locking cardan wheel, only need to step on brake pedal, making the lock projection of brake pedal enter star-like lock tooth makes roller by brake pedal locking, in this process, because the fitting surface between the spacing block set on the locating convex block of brake pedal and support has one at least for intermediate incline, therefore the spacing block set on the locating convex block of brake pedal and support by releasing orientation spacing block set upper locating convex block under be transitioned into lockup state spacing block set at lower locating convex block upper, thus realize phase snap-fit engagement, realize the function of safety self locking of the cardan wheel of belt brake, and needs unclamp pull cardan wheel time, only need the instantaneous force that user provides relatively large, make between the spacing block set on the locating convex block of brake pedal and support by intermediate incline be transitioned into spacing block set upper locating convex block under releasing orientation, thus arming function very easily.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Fig. 9, embodiment provided by the invention, a kind of cardan wheel of belt brake, comprise holder 1, support 2, roller 3, holder 1 is connected with roller 3 by support 2, described roller 3 center shaft is provided with star-like lock tooth 3-1, described support 2 is hinged with brake pedal 4, brake pedal 4 is provided with lock projection 4-1, described lock projection 4-1 can match with the star-like lock tooth 3-1 of roller 3, brake pedal 4 is provided with locating convex block 4-3, described support 2 is provided with spacing block set 2-1, described locating convex block 4-3 is corresponding with spacing block set 2-1 position and can two-way snap-fit engagement back and forth, one is had at least for intermediate incline 5 in two fitting surfaces when two-way clamping back and forth, it is simple that the cardan wheel of this belt brake has structure, can self-locking safety, and the feature of arming function can be facilitated.
As shown in Figure 8, Figure 9, described spacing block set 2-1 cross section is taper arc surface structure, described locating convex block 4-3 cross section is taper arc surface structure, this cross section is the object that the structure of taper circular arc can realize two-way clamping very easily, makes the two-way snap-fit engagement between spacing block set 2-1 and locating convex block 4-3 more reasonable.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Fig. 7, brake pedal 4 is positioned at the top in roller 3 axle center with the hinge-point of support 2, brake pedal 4 is provided with inhibiting device 4-2 away from one end of roller 3 shaft core position, inhibiting device 4-2 can match with the outer wheel face of roller 3, because brake pedal 4 is hinged on support 2, therefore easily brake pedal 4 is stepped on disconnected when trampling brake pedal 4, it is in order to senior general's brake pedal 4 of exerting oneself when preventing from stepping on brake pedal 4 is stepped on disconnected that brake pedal 4 arranges inhibiting device 4-2, the effect of eccentric shaft can be played in top brake pedal 4 and the hinge-point of support 2 being arranged on roller 3 axle center, can ensure to step in the process of brake pedal 4, inhibiting device 4-2 can with roller 3 wheel face abut against and coordinate, with prevent brake pedal 4 stress point single stepped on disconnected.
