Description
Technical field
The present invention relates to and a kind of it is installed on the castor bottom the furniture such as desk, chair, bed, cupboard.
Background technology
Castor comprises the roller being connected to Connection Block bottom furniture, being connected to the bracing frame below Connection Block by the first axis of rotation vertically arranged, be connected on bracing frame by the 2nd axis of rotation arranged in the horizontal direction. There is certain drawback in castor of the prior art. After furniture moves to a certain specified location, can not locate, due to the existence of castor, when furniture still can move by during power.
Summary of the invention
For solving the problem, it is an object of the invention to provide a kind of castor.
In order to reach above object, the technical solution used in the present invention is: castor, the roller that it is comprised Connection Block, is connected to the bracing frame below Connection Block by the first axis of rotation vertically arranged, is connected on bracing frame by the 2nd axis of rotation arranged in the horizontal direction, bracing frame is provided with length vertically arrange and can along the screw rod of self axial rotation, can move up and down and the support seat that is threaded mutually with screw rod. Connection Block is for being connected with furniture. Screw rod and support seat, according to screw mandrel principle, are driven by rotating screw bolt and support moving up and down of seat.
Further, castor has holding state and rolling condition, and when it is when holding state, the bottom supporting seat is lower than roller bottom or equal with roller bottom, and when castor is when rolling condition, the bottom supporting seat is higher than roller bottom.
Further, screw rod is fixedly connected with rotating operation part.
Further, support the chute offered length on seat and vertically arrange, bracing frame has the projection being slidably connected mutually with chute.
Further, supporting and offered an escape groove on seat, roller portion is positioned at this escape groove.
By adopting technique scheme, castor of the present invention, when the mobile furniture of needs, movable support seat makes it bottom higher than roller bottom, then roller is contacted with on ground, it is possible to freely roll, when furniture moves to a certain specified location, movable support seat makes it bottom lower than roller bottom or equal with roller bottom, then support seat and be contacted with on ground, furniture is stood on ground stablely.
Accompanying drawing explanation
Accompanying drawing 1 is the perspective view of castor of the present invention;
What accompanying drawing 2 was castor of the present invention looks up structural representation.
Number in the figure is:
1, Connection Block; 2, bracing frame; 3, roller; 4, screw rod; 5, seat is supported; 6, rotating operation part; 7, chute; 8, projection; 9, escape groove; 10, through hole.
Embodiment
Below in conjunction with accompanying drawing, the better embodiment of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made more explicit defining.
With reference to figures 1 through accompanying drawing 2, castor in the present embodiment, the roller 3 that it is comprised Connection Block 1, is connected to the bracing frame 2 below Connection Block 1 by the first axis of rotation vertically arranged, is connected on bracing frame 2 by the 2nd axis of rotation arranged in the horizontal direction. Connection Block 1 is for being connected with furniture. Connection Block 1 in the present embodiment as shown in figure 1 and 2 is offered multiple through hole 10, for being connected with furniture by Connection Block 1. It is connected by spot contact bearing between Connection Block 1 with bracing frame 2.
Bracing frame 2 is provided with length vertically arrange and can along the screw rod 4 of self axial rotation, can move up and down and the support seat 5 that is threaded with screw rod 4 phase, screw rod 4 is fixedly connected with rotating operation part 6. Screw rod 4 can directly be rotatably connected on Connection Block 1, it is also possible to is directly rotatably connected on bracing frame 2.
Bracing frame 2 in the present embodiment has a container cavity, and roller 3 and support seat 5 are all arranged in this container cavity, and the bottom of bracing frame 2 to be exposed in the bottom of the bottom of roller 3 and support seat 5.
Screw rod 4 and support seat 5, according to screw mandrel principle, drive the shifting up and down supporting seat 5 by rotating screw bolt 4. Castor has holding state and rolling condition, and when it is when holding state, the bottom supporting seat 5 is lower than roller 3 bottom or equal with roller 3 bottom, and when castor is when rolling condition, the bottom supporting seat 5 is higher than roller 3 bottom.
Support the chute 7 offered length on seat 5 and vertically arrange, bracing frame 2 has and the projection 8 that chute 7 phase is slidably connected. Chute 7 and projection 8 one aspect play the effect of guiding, on the other hand, are limited the rotation supported between seat 5 and bracing frame 2 by the cooperation of chute 7 and projection 8.
Supporting and offered an escape groove 9 on seat 5, roller 3 part is positioned at this escape groove 9, to save space, it should be noted that should leave space between the cell wall of roller 3 and escape groove 9, prevents escape groove 9 from affecting the rotation of roller 3.
Above-described embodiment, only for the technical conceive of the present invention and feature are described, its object is to allow person skilled in the art can understand the content of the present invention and implement according to this, can not limit the scope of the invention with this. All equivalences done according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
