Description
Technical field
The utility model relates to a kind of castor.
Background technology
The brake facing of existing castor, riveting dress mode is adopted to link pedal and brake facing, heat treatment was not at that time, easily fracture, castor is made to lose brake function, lower pearl dish originally and brake facing combination are that the one side of lower pearl dish directly makes brake disc, when load-bearing torsion is too large, cause lower pearl dish to be easily out of shape, steel ball comes off, castor is caused to use, brake facing is originally connected the employing both sides punching press of neck position with stretcher, contact surface is smaller, easily ruptures, must change whole castor after brake facing fracture, maintenance cost height waits shortcomings.
Utility model content
For the weak point existed in the problems referred to above, the utility model provides a kind of castor.
For achieving the above object, the utility model provides a kind of castor, comprising:
Lower pearl dish, be provided with brake disc above described lower pearl dish, described brake disc edge is evenly provided with multiple brake double wedge;
The rack leg of two same structures is arranged on both sides, described lower pearl dish top;
Described rack leg side is suppressed with protruding button bit;
Brake facing both sides are suppressed with the button bit interlocked with described protruding button bit, described brake facing rear end is provided with the card matched with described brake double wedge, described brake facing front portion is provided with multiple anti-skidding fulcrum, described brake facing front part sides is overall neck position, and described brake facing top is connected to the arc place in the middle part of stretcher;
Wheel is bolted between described two rack legs.
Improve further as the utility model, described anti-skidding fulcrum is seven.
Improve further as the utility model, described card is zig-zag.
The beneficial effects of the utility model are: mounting process is convenient, reduce costs, the reliability that product links strengthens, when brake facing damages, easy to maintenance, by recovering the use of castor after replacing brake facing, brake facing adopts overall convex bit architecture in wheel position of stopping, in use procedure, brake safer, reliable and increase the wheel place increase by two of stopping of durability brake facing and arrange seven anti-skidding fulcrums, increasing brake security.

Detailed description of the invention
As Figure 1-4, a kind of castor described in the utility model embodiment, comprising: lower pearl dish 7, and described lower pearl dish 7 is provided with brake disc 8 above, and described brake disc 8 edge is evenly provided with multiple brake double wedge; The rack leg 2 of two same structures is arranged on both sides, described lower pearl dish 7 top; Described rack leg 2 side is suppressed with protruding button bit 3; Brake facing 4 both sides are suppressed with the button bit 10 interlocked with described protruding button bit 3, described brake facing 4 rear end is provided with the card 12 matched with described brake double wedge, described brake facing 4 front portion is provided with multiple anti-skidding fulcrum 9, described brake facing 4 front part sides is overall neck position 11, and described brake facing 4 top is connected to the arc place in the middle part of stretcher 5; Wheel 1 is fixed between described two rack legs 2 by bolt 6, and described anti-skidding fulcrum 9 is seven, and described card 12 is zig-zag.Mounting process is convenient, reduces costs, and the reliability that product links strengthens, easy to maintenance, reliable, increase brake security.
During concrete use: lower pearl dish installs brake disc in addition, increase the bearing capacity of castor, brake facing and rack leg adopt spiral-lock mode to install, left and right rack leg passes through impact style, punch forming two protruding button bits, and the button bit snapping on brake facing, rack leg and brake facing are linked by snapping, mounting process is convenient, reduces costs, and the reliability that product links strengthens.When brake facing damages, easy to maintenance, by recovering the use of castor after replacing brake facing, brake facing adopts overall convex bit architecture in wheel position of stopping, and in use procedure, brakes safer, reliable and increases durability, make castor more durable, brake facing and stretcher neck position now adopt overall fastening piece structure, and brake facing neck position and stretcher are at junction full face contact, and during brake, brake facing can not rupture.Brake facing wheel place of stopping increases into two rows, seven anti-skidding fulcrums, increases brake security.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
