Description
Technical field
Castor is the utility model is related to, it is particularly a kind of from hard braking revolving chair leg wheel.
Background technology
For traditional caster brake structure usually as an independent structure, it can be divided into single brake (only checking wheel face) and full brake
(while checking wheel face and rotating disk).Both brake structures are required for coordinating specific braking bracket ready for installation, it is necessary to multiple
Part is assembled, and at the same time, the installation of brake is complicated, makes more complicated traditional Castor structure, production and assembly cost
It is higher, while the volume of traditional castor is larger, is not suitable for use on household goods.
Utility model content
For overcome the deficiencies in the prior art, a kind of simple in construction, easy to assembly, compact of the utility model offer,
And the castor with brake function.
Technical scheme is used by the utility model solves its technical problem：
It is a kind of from hard braking revolving chair leg wheel, including wheel carrier, roller, wheel shaft；The roller inner central is installed provided with wheel shaft
Seat, the wheel shaft mounting seat are provided with wheel shaft mounting hole, and the wheel shaft mounting seat outer wall is provided with annular groove；Set on the wheel carrier
There is bottom plate mounting seat, the bottom plate mounting seat is in the perforate of wheel carrier top；Hollow base is provided with by the bottom plate mounting seat, in described
Spring, movable block are sequentially provided with space base seat, through hole is provided with the movable block；The hollow base both sides are provided with matches somebody with somebody with through hole
The axle hole of conjunction, the axle hole are oval；The hollow base both sides are provided with brake shoes, and the brake shoes is provided with and ring
The double wedge that shape groove coordinates, the brake shoes are located at axle hole top.
As a preference, the wheel shaft both sides are respectively equipped with two sections of grooves.
As a preference, the groove coordinates with the annular bead in wheel shaft mounting hole.
As a preference, the double wedge includes high tooth, the short tooth positioned at high between cog located at brake shoes both ends；It is described
Short between cog is provided with neck.
The beneficial effects of the utility model are：This castor in use, under affected by gravity, makes under wheel carrier
It is mobile, make to be mutually twisted between annular groove and double wedge, roller is not rolled, play a part of brake；After gravity is withdrawn, wheel
Frame is resetted in the presence of hollow base inner spring, and annular groove is engaged with being released between double wedge, makes roller rotatable；This castor profit
The effect for resistance of stopping is produced with self structure, eliminates brake structure part, makes Castor structure compact simple, and can realize compact
Change, may be used on the furniture such as swivel chair.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is schematic perspective view of the present utility model；
Fig. 2 is brake shoes enlarged diagram of the present utility model；
Fig. 3 is roller schematic diagram of the present utility model.
Embodiment
1~Fig. 3 of reference picture, it is a kind of from hard braking revolving chair leg wheel, including wheel carrier 1, roller 2, wheel shaft 3；The inner side of roller 2
Center is provided with wheel shaft mounting seat 21, and the wheel shaft mounting seat 21 is provided with wheel shaft mounting hole 22, installed by taking turns shaft mounting hole 22
Wheel shaft 3, roller 2 is connected with each other, the outer wall of wheel shaft mounting seat 21 is provided with annular groove 23；The wheel carrier 1 is provided with bottom plate
Mounting seat 11, the bottom plate mounting seat 11 pass through the mounting base of bottom plate mounting seat 11 in the top perforate of wheel carrier 1；The bottom plate peace
The side of dress seat 11 is provided with hollow base 12, is sequentially provided with spring 121, movable block 122 in the hollow base 12, movable block 122 can
Upper and lower displacement is done in hollow base 12 in the presence of spring 121, through hole A12 is provided with the movable block 122；In described
The both sides of space base seat 12 be provided with through hole A12 coordinate axle hole 123, the axle hole 123 is oval, wheel shaft 3 by through
Shaft mounting hole 22 and through hole A12 are taken turns, roller 2 is arranged on wheel carrier 1, to enable wheel shaft 3 to produce upper and lower displacement, by wheel shaft
Mounting hole 22 designs ovalisation；The both sides of hollow base 12 are provided with brake shoes 124, and the brake shoes 124 is provided with and ring
The double wedge B12 that shape groove 23 coordinates, the brake shoes 124 are located at the top of axle hole 123, in the presence of by weight, roller 2
Moving up for relative wheel carrier 1 is produced, annular groove 23 is contacted with each other and is engaged with double wedge B12, roller 2 is not rotated, is produced
The effect of brake resistance.
Because roller 2 is as a part important in resistance effect of stopping is produced, must ensure to be completely embedded between wheel shaft 3, therefore
The both sides of wheel shaft 3 are respectively equipped with two sections of grooves 31, and the annular bead coordinated with groove 31 is provided with wheel shaft mounting hole 22
221。
