The body 10 has a fixing portion 100 and a containing portion 102. The fixing portion 100 is in the form of a sheet. The accommodating portion 102 is disposed on the fixing portion 100, in the embodiment, the accommodating portion 102 is disposed at the center of the fixing portion 100, and the accommodating portion 102 and the fixing portion 100 are integrally formed. The accommodating portion 102 is a cylinder in appearance, an opening 104 is disposed at the bottom of the accommodating portion 102, and a through hole 106 is disposed at the top of the accommodating portion 102, in this embodiment, the aperture of the through hole 106 is smaller than the aperture of the opening 104, but the present invention is not limited to the aperture of the through hole 106 being smaller than the aperture of the opening 104.

The connecting portion 20 is a circular cylinder and is hollow, and the connecting portion 20 penetrates through the opening 104 and the through hole 106. The linking member 30 is disposed around the periphery of the combining portion 20 and located inside the accommodating portion 102, in this embodiment, the linking member 30 is a steel ball ring. The linking seat 40 is disposed around the periphery of the combining portion 20 and located in the accommodating portion 102, and carries the linking member 30. A shaft hole 500 of the wheel 50 is aligned with a pivot hole 200 of the combining portion 20. The axle 60 is disposed through the pivot hole 200 and the axle hole 500 of the wheel body 50.

Please refer to fig. 3 and fig. 4, which are a schematic cross-sectional view of a caster according to embodiment 1 of the present invention and a schematic cross-sectional view from another perspective. As shown in the figures, the caster of the present invention is assembled in such a manner that the coupling member 20 passes through the through hole 106 and the opening 104 of the accommodating portion 102 of the body 10, then the linking member 30 is mounted on the periphery of the coupling portion 20 and located in the accommodating portion 102, and then the linking seat 40 is mounted on the periphery of the coupling portion 20 and located in the accommodating portion 102 and carrying the linking member 30. Next, the wheel body 50 is partially received in the combining portion 20, the axle hole 500 of the wheel body 50 is aligned with the pivot hole 200 of the combining portion 20, and then the axle 60 is inserted through the pivot hole 200 and the axle hole 500 of the wheel body 50. Thus, the coupling member 30 and the coupling seat 40 are annularly arranged on the periphery of the combining portion 20 and are located in the accommodating portion 102, so that the furniture has the advantages of thin thickness, simple structure and good stability when bearing objects, and the aesthetic feeling of the furniture cannot be damaged when the furniture is applied; when the folding type electric mahjong table is applied to the electric mahjong table, the height of the electric mahjong table accords with the human engineering without influencing the health of the electric mahjong table, the service life can be prolonged, the stability of the electric mahjong table is good when the load bearing object is increased, and the folding type electric mahjong table can not topple over towards the folding side of the table top in the carrying and moving processes after being folded.

Furthermore, the utility model discloses a locate the wheel body 80 of truckle in conjunction 50, and link 60 and interlock seat 70 ring locate the periphery of conjunction 50 to be located holding portion 402, make the rotation center of truckle be located wheel body 80, and can avoid structural deformation, and then increase life. In addition, the caster structure of the present invention can be formed only by the body 40, the connector 50, the linkage 60, the linkage seat 70, the wheel body 80 and the wheel axle 90, and the caster structure has a simple structure, so as to reduce the cost.

As shown in fig. 3 and 4, the outer periphery of the joint portion 20 of the present invention is provided with a convex ring 202. After the coupling portion 20 passes through the through hole 106 and the opening 104 of the accommodating portion 102 of the body 10, the protruding ring 202 abuts against the top of the accommodating portion 102. Thus, the present invention prevents the body 10 from falling off from the top by the protruding ring 202 abutting against the top of the accommodating portion 102.

Furthermore, the length of the wheel axle 60 of the present invention is greater than the length of the axle hole 500 of the wheel body 50 plus the length of the pivot holes 200 on the two sides of the wheel body 50, and the wheel axle 60 exposed in the axle hole 500 of the wheel body 50 is abutted against the linkage seat 40 to fix the linkage seat 40 and prevent the linkage seat 40 from falling downward. As can be seen from the above, the protruding ring 202 of the present invention abuts against the top of the accommodating portion 102 and the wheel axle 60 abuts against the coupling seat 40, so that the body 10, the coupling member 30 and the coupling seat 40 are fixed between the protruding ring 202 and the wheel axle 60.

In addition, as shown in fig. 2, the combining portion 20 of the present embodiment is provided with an external thread 204, and the linking seat 40 is provided with an internal thread 400 corresponding to the external thread 204, so that the linking seat 40 is fixed on the periphery of the combining portion 20.

In addition, since the linking member 30 is a ball ring, in order to avoid the balls from running on the linking seat 40, a concave arc-shaped lower ball groove 402 is formed on the upper surface of the linking seat 40 corresponding to the ball ring, so as to control the balls to slide on the lower ball groove 402.

Furthermore, if only the lower ball groove 402 is used, the steel ball may be separated from the lower ball groove 402 by external force, so in the present embodiment, an annular flange 108 is disposed on the top of the accommodating portion 102 of the body 10, and the lower surface of the annular flange 108 corresponds to the lower ball ring 402, and an annular concave arc-shaped upper ball groove 1080 is disposed to control the sliding of the steel ball between the upper ball groove 1080 and the lower ball groove 402.

Please refer to fig. 5 and fig. 6, which are a schematic sectional view and a schematic bottom view of a caster according to embodiment 2 of the present invention. As shown in the drawings, the difference between the present embodiment and the above embodiments is that the bottom of the linking seat 40 of the present embodiment is provided with two locking holes 404 opposite to the two ends of the wheel axle 60, and the two locking members 70 respectively correspond to the locking holes 404 and pass through the wheel axle 60 to be locked in the locking holes 404, so as to fix the linking seat 40.

As shown in fig. 6, in order to facilitate the fine adjustment of the wheel 50 disposed at the position of the ring of the coupling seat 40, 5 locking holes 404 are disposed at the bottom of the coupling seat 40, and the locking holes 404 are disposed at the bottom of the coupling seat 40 on average, i.e., the locking holes 404 are disposed at intervals of 72 degrees at the bottom of the coupling seat 40, so that the angle between the locking holes 404 fixed at the two ends of the wheel axle 60 is 144 degrees, thereby achieving the purpose of fine adjustment of the wheel 50 in 5 different directions.

In addition, wheel 80 is eccentrically disposed in opening 104 of body 10, i.e. wheel 50 is not located at the center of opening 404, so as to facilitate turning of caster 1.
