Abstract

The utility model relates to an improved brake caster which comprises an inserted rod, a support, a wheel, a pedal and a brake block, wherein the inserted rod is pivotally connected with and the support through an upper bead disc and a lower bead disc. The improved brake caster is characterized in that the brake block is installed at the top part of the pedal, and the pedal is installed in the inner side of the support; disc tooth are arranged at the radial circumference of the lower bead disc; brake teeth are also arranged on the brake block, and the brake teeth are meshed with the disc teeth during the braking process. Since the structure is adopted, when the pedal is trampled, the wheel axle is pushed by the pedal to move on the support, the brake block is braked with the wheel in a matching way, and meanwhile, the brake teeth on the brake block are meshed with the disc teeth on the lower bead disc, so as to prevent the wheel from rotating in the horizontal plane. The improved brake caster can not only brake the wheel and also can prevent the wheel from rotating in the horizontal plane.

Description

A kind of improved brake castor

Technical field

The utility model relates to a kind of castor, especially a kind of brake equipment caster wheel that has.

Background technology

Present prior art, a kind of brake castor comprises inserted link, support, wheel, pedal and slipper, inserted link articulates by last pearl dish, following pearl dish and support; On the pedal end be step on the end of stopping, the other end is the end that travels, pedal and support articulate, caster axle can move in the breaker slot of pedal, guide groove on the support; Slipper is installed on the support on castor top.Existing problems are: glancing impact, and wheel is no longer moved forward, can not prevent that wheel from rotating in horizontal surface.

Summary of the invention

The purpose of this utility model is: a kind of improved brake castor is provided, and it can not only brake wheel, and can prevent that wheel from rotating in horizontal surface.

The utility model is achieved in that a kind of improved brake castor, comprise inserted link, support, wheel, pedal and slipper, inserted link articulates with support by last pearl dish, following pearl dish, and its special character is: described slipper is installed in the top of pedal, and pedal is installed in support the inboard; The radial periphery of the described dish of pearl down has the dish tooth; Also have brake tooth on the described slipper, described brake tooth meshes with the dish tooth when brake.

A kind of improved castor of the utility model, described slipper is installed in the top of pedal, and pedal is installed in support the inboard; The radial periphery of the described dish of pearl down has the dish tooth; Also have brake tooth on the described slipper, described brake tooth meshes with the dish tooth when brake.Owing to adopt such structure, when pushes pedals, pedal promotes wheel shaft and moves at support, and slipper cooperates braking with wheel, and meanwhile, the dish tooth engagement with following pearl dish is nibbled in the braking on the slipper, prevents that wheel from rotating in horizontal surface.So it can not only brake wheel, and can prevent that wheel from rotating in horizontal surface.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1 and Figure 2, a kind of brake castor comprises inserted link 1, support 5, wheel 6, pedal 8 and slipper 9, and inserted link 1 articulates with support 5 by last pearl dish 2, following pearl dish 3; Steel ball groove on the upper and lower end face of the top board of support 5 also has guide groove 52 on the support 5; Last pearl dish 2, pearl dish 3 also has the steel ball groove down, steel ball 4 be installed in support 5 top board, go up pearl dish 2, down in the steel ball groove of pearl dish 3.Inserted link 1 is fixedly connected with last pearl dish 2, following pearl dish 3.As shown in Figure 3, on the pedal 8 end be step on the end 81 of stopping, the other end is the end 82 that travels, and also has hinge hole 83, driver slot 84 on the pedal 8, the hinge hole 83 of pedal 8 articulates by jointed shaft 51 with support 5, pedal 8 is installed in support 5 inboard; Caster axle 7 can move in the breaker slot 84 of pedal 8, guide groove 52 on the support 5; As Fig. 2, shown in Figure 3, slipper 9 is installed in the top of pedal 8.

As Fig. 4, Fig. 5, shown in Figure 6, the radial periphery of the described dish of pearl down 3 has dish tooth 31;

As Fig. 7, Fig. 8, shown in Figure 9, also have brake tooth 92 on the described slipper 9, described brake tooth 92 meshes with dish tooth 31 when brake, and the detent 91 on the slipper 9 cooperates with wheel.

The connector 93 of slipper 9 is installed in the bar hole 85 on the pedal 8.Slipper 9 can be along the bar hole up-and-down movement.

Claims

1, a kind of improved brake castor comprises inserted link, support, wheel, pedal and slipper, and inserted link articulates with support by last pearl dish, following pearl dish, and it is characterized in that: described slipper is installed in the top of pedal, and pedal is installed in support the inboard; The radial periphery of the described dish of pearl down has the dish tooth; Also have brake tooth on the described slipper, described brake tooth meshes with the dish tooth when brake.
