Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing and specific implementation
Example, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only to explain this hair
It is bright, but not to limit the present invention.
Referring initially to shown in Fig. 1, Fig. 1 is the structural schematic diagram of universal wheel 20 of the invention.Universal wheel 20 includes mounting plate
1, wheel support 3 and idler wheel 5.Mounting plate 1 has axially extending centre bore 101, and wheel support 3 is arranged below mounting plate 1 and peace
Loading board 1 is rotatablely connected, and idler wheel 5 is rotatably arranged on wheel support 3.
Further, also referring to shown in Fig. 1 and Fig. 2, universal wheel 20 includes retaining mechanism, and retaining mechanism includes braking
Bar 2, brake disc 9 and brake block 4.
Brake bar 2 is arranged in the centre bore 101 of mounting plate and one end is pierced by from centre bore 101, brake bar 2 it is another
End is extended downwardly to be coupled with brake disc 9, and brake disc 9 and 4 elastic connection of brake block and brake disc 9 and brake block 4 are selectively
It is engaged, brake block 4 has the brake lining being coupled with idler wheel 5.
In a specific embodiment, universal wheel 20 further includes the thrust being arranged between mounting plate 1 and wheel support 3
Bearing 6, thrust bearing 6 pass through the realization axial restraint of circlip 8 that 1 lower end of mounting plate is arranged in.
In a specific embodiment, reset brake bar 2 first is provided in the centre bore 101 of mounting plate 1
Elastic component 7.It example but does not limit, the first elastic component 7 can be spring.
Preferably, the second elastic component for separating brake disc 9 and brake block 4 is provided between brake disc 9 and brake block 4
10.It example but does not limit, the second elastic component 10 can be spring.
In a specific embodiment, brake bar 2 and brake disc 9 are coupled by screw 102, and screw 102 is from lower past
On be coupled across one end (lower end) screw thread of brake block 4, the second elastic component 10 and brake disc 9 and brake bar 2.
In a specific embodiment, brake disc 9 is engaged with brake block 4 optionally by two gear disk, fluted disc
Tooth form is triangle.
Fig. 2 is the schematic diagram of the section structure of universal wheel, wherein installed thrust bearing 6 between mounting plate 1 and wheel support 3, and
Realize that axial restraint, brake bar 2 sequentially pass through the first elastic component 7, peace from top to bottom by circlip 8 in 1 lower end of mounting plate
Loading board 1 and brake disc 9, screw 102 sequentially passes through pressing plate 11, brake block 4 and the second elastic component 10 from lower to upper, and is screwed into system
The lower thread hole of lever 2 is attached.
Preferably, mounting plate 1 and the mating part and brake bar 2 and the mating part of brake disc 9 of both brake bars 2 are equal
Cooperated using waist hole form, to prevent brake bar 2 and brake disc 9 from generating rotation during locking.
When the locking mechanism is in an unlocked state, i.e., it is in original state without each components of universal wheel under external force, this
When brake disc 9, brake block 4 and idler wheel 5 be in discrete state.
When brake bar 2 is moved downward by external force, retaining mechanism can be made to may be at locking state.It is locking
Determine under state, brake disc engages cooperation with brake block, and brake block is locked with idler wheel.
Also referring to shown in Fig. 1 to Fig. 3, during locking to retaining mechanism, brake bar 2 is pushed, first
Elastic component 7 compresses, and brake bar 2 drives brake disc 9, the second elastic component 10, brake block 4, pressing plate 11 to move down together；Work as braking
After block 4 touches idler wheel 5, the second elastic component 10 compresses, the fluted disc engagement of brake block 4 and brake disc 9, basis in engagement process
The two tooth top is different from the angle of tooth root, and wheel support 3 can generate small rotation；After brake block 4 and the engagement of brake disc 9 are completed
Universal locking can be achieved.Although brake block 4 is contacted with idler wheel at this time, locking idler wheel completely is not perpendicular to ground direction
On rolling.Brake block 4 can be made more to be pressed into idler wheel 5 when continuing to push, be at this time while realizing to 5 rolling square of idler wheel
To the locking with universal direction, i.e. retaining mechanism is in locking state.
After take-off the brake bar 2, the second elastic component 10 is returned to original state by compressive state, makes brake disc 9 and braking
The engagement of block 10 is detached from, and universal locking releases；First elastic component 7 is returned to original state by compression, makes brake bar 2, brake disc
9, the second elastic component 10, brake block 4, pressing plate 11 are moved upward to original state, roll lock release.
A kind of achievable rolling provided by the invention and universal while locking universal wheel, locking effect are better than only locking
The universal wheel of rotating direction；And rolling and universal castor can be locked simultaneously relative to other, structure is simpler, and stability is more
Good, manufacture is at more originally low.
Universal wheel of the present invention is suitable for various industry, household, Medical Devices etc., and mounting height is lower, saves empty
Between, structure is simple, and stability is preferable.
The above described specific embodiments of the present invention are not intended to limit the scope of the present invention..Any basis
Any other various changes and modifications made by technical concept of the invention should be included in the guarantor of the claims in the present invention
It protects in range.
