Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In addition, in the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0019] In the description of this specification, the description of the term "as an alternative embodiment" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one alternative embodiment or alternative example of the present utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0020] Combined Figure 1 and Figure 2 As shown, in the first aspect of this embodiment, a caster is provided, which includes a fixed seat and a caster body 10, wherein:

[0021] The middle part of the fixed seat is provided with a movable shaft 40, a connecting seat 50, a shaft sleeve 60 and an elastic member 70. One end of the movable shaft 40 is connected to the caster body 10 through the connecting seat 50. The other end of the movable shaft 40 passes through the shaft sleeve 60. The elastic member 70 is sleeved outside the movable shaft 40. One end of the elastic member 70 abuts against the connecting seat 50, and the other end of the elastic member 70 abuts against the shaft sleeve 60. The elastic member 70 can generate an elastic force that causes the movable shaft 40 to move in the vertical direction. The movable shaft 40 drives the caster body 10 to move in the vertical direction through the connecting seat 50. Thus, the caster body 10 and the fixed seat are flexibly connected through the movable shaft 40, the connecting seat 50, the shaft sleeve 60 and the elastic member 70. When the caster body 10 encounters a higher ground, the caster body 10 can move upward in the vertical direction through the connecting seat 50 and the movable shaft 40, avoiding the situation that the caster body 10 is fixed or cannot be pushed. When the caster body 10 encounters a lower ground, the elastic member 70 in the compressed state can push the connecting seat 50 to move downward in the vertical direction, so that the connecting seat 50 drives the caster body 10 and the movable shaft 40 to move downward in the vertical direction, avoiding the situation that the caster body 10 is suspended. Thus, the height adjustment of the caster body 10 can be realized, and the caster has a buffering effect, which is beneficial to improving the service life of the caster. In addition, the movable shaft 40 is arranged in the shaft sleeve 60, and the movable shaft 40 can move in the shaft sleeve 60 in the vertical direction, which can reduce the resistance of the movable shaft 40 moving in the vertical direction, make the movable shaft 40 move more smoothly, and is beneficial to improving the service life of the movable shaft 40 and reducing the cost of the caster.

[0022] On the basis of the above embodiments, as an optional implementation manner, the connecting seat 50 includes a first connecting portion 51 and a second connecting portion 52. The first connecting portion 51 and the second connecting portion 52 are integrally formed and connected. The diameter of the first connecting portion 51 is larger than the diameter of the second connecting portion 52, so that the cross-sectional shape of the connecting portion 50 is in a T shape. Among them, the first connecting portion 51 abuts against the elastic member 70, and the second connecting portion 52 can move relative to the fixed seat in the vertical direction. Thus, when the second connecting portion 52 moves in the vertical direction, the first connecting portion 51 also moves in the vertical direction to compress the elastic member 70 to generate an elastic force that causes the movable shaft 40 to move in the vertical direction.

[0023] Based on the above embodiments, as an alternative embodiment, the fixing base includes a first fixing base 20 and a second fixing base 30. The first fixing base 20 and the second fixing base 30 are detachably connected. A first receiving cavity is provided in the middle of the first fixing base 20, and a second receiving cavity is provided in the middle of the second fixing base 30. The movable shaft 40, the shaft sleeve 60, the elastic member 70, and the first connecting portion 51 are all located in the first receiving cavity. The diameter of the first connecting portion 51 is greater than the diameter of the second receiving cavity, and at least a part of the second connecting portion 52 is located in the second receiving cavity. Thus, when the second connecting portion 52 moves in the vertical direction, the second connecting portion 52 can move into the first receiving cavity, while the first connecting portion 51 can abut against the second fixing base 30 but cannot move into the second receiving cavity, thereby ensuring the stability of the connection between the connecting seat 50, the caster body 10, and the fixing base, preventing the caster body 10 from detaching from the fixing base during movement, and enabling the height adjustment of the caster body 10. As an alternative embodiment, the first fixing base 20 and the second fixing base 30 can be detachably connected by threaded members, which facilitates the installation of the movable shaft 40, the shaft sleeve 60, the elastic member 70, and the connecting member 50 in the first and second receiving cavities. At the same time, when the above components are damaged, it is also convenient to replace them in a timely manner, which is beneficial to further reducing the cost of the caster.

[0024] Based on the above embodiments, as an alternative embodiment, a bearing 80 is further included. The bearing 80 is installed on the second fixing base 30 and is located in the second receiving cavity. The second connecting portion 52 is disposed within the bearing 80, and the second connecting portion 52 can move vertically within the bearing 80. Thus, by disposing the second connecting portion 52 within the bearing 80, when the second connecting portion 52 moves in the vertical direction, the resistance of the second connecting portion 52 moving in the vertical direction can be reduced, making the movement of the second connecting portion 52 smoother, which is beneficial to further increasing the service life of the movable shaft 40.

[0025] Based on the above embodiments, as an alternative embodiment, the movable shaft 40 and the connecting seat 50 are detachably connected, and the caster body 10 and the connecting seat 50 are detachably connected. Specifically, a threaded hole can be provided in the middle of the connecting seat 50, threads can be provided on the movable shaft 40 and the caster body 10, and the movable shaft 40 and the connecting seat 50 are threadedly connected, and the caster body 10 and the connecting seat 50 are threadedly connected. Thus, when the caster body 10 and the movable shaft 40 are worn, they can be easily replaced, which is beneficial to further reducing the cost of the caster.

[0026] Based on the above embodiments, as an alternative embodiment, an installation hole is provided at one end of the first fixing base 20 facing away from the second fixing base 30. Specifically, a flange can be provided at one end of the first fixing base 20 facing away from the second fixing base 30, and the installation hole is provided on the flange. Thus, it is convenient to connect the fixing base to the dust cover of the winding machine.

[0027] Combined Figure 3 As shown, the second aspect of this embodiment provides a dust cover for a winding machine. The dust cover for the winding machine includes the casters 1 described in the first aspect. The casters can be installed on the frame 2 of the dust cover for the winding machine through the mounting holes on the first fixing seat 20. A door 3 is installed on the frame 2, which facilitates the operator to open and close the door and also makes the door more stable.

[0028] In the dust cover for the winding machine provided in this embodiment, the casters can achieve height adjustment and have a buffering effect. The casters can adjust the height in a timely manner with the fluctuation of the ground height, which can avoid the situation that the casters are suspended or cannot be pushed, thereby contributing to extending the service life of the door and reducing the use cost of the dust cover for the winding machine.
