Abstract
The invention discloses a caster with a brake. The caster comprises a connecting base, a support frame and an idler wheel, wherein the support frame is rotationally connected with the lower part of the connecting base through a first rotating shaft arranged in the vertical direction; the idler wheel is rotationally connected onto the support frame through a second rotating shaft arranged in the horizontal direction; a brake mechanism used for limiting the rotation of the idler wheel is arranged on the support frame and comprises a brake block rotationally connected onto the support frame and having elasticity, and a pedal rotationally connected with the brake block; a clamping hole is formed in the brake block; when the brake mechanism is in the release state, the clamping hole is separated from the idler wheel, and when the brake mechanism is in the braking state, the clamping hole is propped against the idler wheel. The edge of the clamping hole can increase the friction between the brake block and the idler wheel. By adopting the technical scheme, the caster with the brake has the advantage that through the effect of the clamping hole, the idler wheel is fixed more reliably through the brake block during braking.

detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
with reference to figures 1 through accompanying drawing 4, the castor of a kind of belt brake in the present embodiment, it comprise Connection Block 1, by the first rotating shaft 14 vertically arranging be rotatably connected on the bracing frame 2 of Connection Block 1 below, the second rotating shaft 15 arranging by along continuous straight runs is rotatably connected on the roller 3 on bracing frame 2.Connection Block 1 is for being connected with furniture.On Connection Block 1 in the present embodiment as shown in Figure 1, offer multiple through holes 9, for Connection Block 1 is connected with furniture.Between Connection Block 1 and bracing frame 2, be connected by ball bearing of main shaft.On bracing frame 2, be provided with the braking mechanism that restriction roller 3 rotates.
braking mechanism comprise be rotatably connected on bracing frame 2 and have elastomeric brake facing 5, with brake facing 5 pedal 6 being connected that rotates, rotate pedal 6 braking mechanism changed between release position and braking state by pressing.In the present embodiment as shown in attached Fig. 1 and 2, brake facing 5 is rotatably connected on bracing frame 2 by the 3rd rotating shaft 16, and pedal 6 is rotatably connected on brake facing 5 by the 4th rotating shaft 17.On brake facing 5, offer hole clipping 7.When braking mechanism is during in release position, hole clipping 7 departs from roller 3, and when braking mechanism is during in braking state, hole clipping 7 is against on roller 3.In the more preferred scheme of one, the edge way roller 3 of hole clipping 7 is formed slopely flange 10.
