Abstract
The invention discloses a caster. The caster comprises a connecting base, a supporting frame, a rolling wheel, a threaded rod and a supporting base, wherein the supporting frame is rotationally connected below the connecting base through a first rotary shaft arranged in the vertical direction, the rolling wheel is rotationally connected to the supporting frame through a second rotary shaft arranged in the horizontal direction, the threaded rod is arranged on the supporting frame and can rotate along the axial direction of the threaded rod, the length of the threaded rod is arranged in the vertical direction, and the supporting base can move vertically and is connected with the threaded rod through threads. By the adoption of the technical scheme, due to the caster, when a piece of furniture needs to be moved, the supporting base is moved to make the bottom end of the supporting base higher than the bottom end of the rolling wheel, and the rolling wheel makes contact with the ground and can freely roll; when the piece of furniture moves to some specific position, the supporting base is moved to make the bottom end of the supporting base lower than the bottom end of the rolling wheel or flush with the bottom end of the rolling wheel, the supporting base makes contact with the ground, and then the furniture can stand on the ground stably.
Description
technical field
the present invention relates to a kind of castor that is installed on the furniture bottoms such as desk, chair, bed, cupboard.
background technology
castor comprise be connected in the Connection Block of furniture bottom, by the first rotating shaft vertically arranging be rotatably connected on the bracing frame of Connection Block below, the second rotating shaft arranging by along continuous straight runs is rotatably connected on the roller on bracing frame.There is certain drawback in castor of the prior art.When furniture moves to after a certain assigned address, can not locate, due to the existence of castor, in the time that furniture is stressed, still can move.
summary of the invention
for addressing the above problem, the object of the present invention is to provide a kind of castor.
in order to reach above object, the technical solution used in the present invention is: castor, it comprise Connection Block, by the first rotating shaft vertically arranging be rotatably connected on the bracing frame of Connection Block below, the second rotating shaft arranging by along continuous straight runs is rotatably connected on the roller on bracing frame, is provided with that length vertically arranges and can be along the screw rod of self axial rotation, the supporting seat that can move up and down and be threaded mutually with screw rod on bracing frame.Connection Block is for being connected with furniture.Screw rod and supporting seat, according to screw mandrel principle, drive moving up and down of supporting seat by rotating screw bolt.
further, castor has holding state and rolling condition, and when it is during at holding state, the bottom of supporting seat is lower than roller bottom or equal with roller bottom, and when castor is during at rolling condition, the bottom of supporting seat is higher than roller bottom.
further, on screw rod, be fixedly connected with rotating operation part.
further, on supporting seat, offer the chute that length vertically arranges, on bracing frame, there is the projection with chute phase sliding block joint.
further, offer one and dodge groove on supporting seat, roller portion is positioned at this and dodges groove.
by adopting technique scheme, castor of the present invention, in the time of needs moving furniture, movable support seat makes it bottom higher than roller bottom, and roller contact, can Free-rolling on ground, in the time that furniture moves to a certain assigned address, movable support seat makes it bottom lower than roller bottom or equal with roller bottom, and supporting seat is contacted with on ground, and furniture is stably stood on ground.
brief description of the drawings
the perspective view that accompanying drawing 1 is 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, supporting seat; 6, rotating operation part; 7, chute; 8, projection; 9, dodge groove; 10, through hole.
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 2, castor in the present embodiment, it comprise Connection Block 1, by the first rotating shaft vertically arranging be rotatably connected on the bracing frame 2 of Connection Block 1 below, the second rotating shaft 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 attached Fig. 1 and 2, offer multiple through holes 10, 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 that length vertically arranges and can, along the screw rod 4 of self axial rotation, the supporting seat 5 that can move up and down and be threaded mutually with screw rod 4, be fixedly connected with rotating operation part 6 on screw rod 4.Screw rod 4 can directly be rotatably connected on Connection Block 1, also can directly be rotatably connected on bracing frame 2.
bracing frame 2 in the present embodiment has a container cavity, and roller 3 and supporting seat 5 are all arranged in this container cavity, and the bottom that will expose bracing frame 2, the bottom of the bottom of roller 3 and supporting seat 5.
screw rod 4 and supporting seat 5 be according to screw mandrel principle, by rotating screw bolt 4 drive supporting seat 5 on move down.Castor has holding state and rolling condition, and when it is during at holding state, the bottom of supporting seat 5 is lower than roller 3 bottoms or equal with roller 3 bottoms, and when castor is during at rolling condition, the bottom of supporting seat 5 is higher than roller 3 bottoms.
on supporting seat 5, offer the chute 7 that length vertically arranges, on bracing frame 2, there is the projection 8 with chute 7 phase sliding block joints.Chute 7 and projection 8 play the effect of guiding on the one hand, on the other hand, limit the rotation between supporting seat 5 and bracing frame 2 by the cooperation of chute 7 and projection 8.
on supporting seat 5, offer one and dodge groove 9, roller 3 parts are positioned at this and dodge groove 9, to save space, but it should be noted that roller 3 and dodge between the cell wall of groove 9 and should leave space, prevent that dodging groove 9 affects the rotation of roller 3.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
