DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantage of the embodiment of the utility model more clear, the technical scheme in the embodiment of the utility model is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0024] The embodiment of the application provides a protective caster support, which solves the problem that the protective shell cannot be sleeved outside the caster through the fixing hole diameter opening at the caster body, so that the protective shell cannot block the caster from carrying impurities into the caster body, and the parts in the caster body are affected by the impurities for a long time, so that the normal use of the caster body and the caster at the caster body is affected, and the adjustment of the opening hole diameter of the bottom surface of the protective shell is realized.

[0025] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and specific embodiments.

[0026] The embodiment of the utility model discloses a protective caster support.

[0027] According to the drawings Figures 1-5 As shown, it comprises a top cover 1 and a connecting support 2 rotatably arranged at the bottom surface of the top cover 1, and the top cover 1 and the connecting support 2 form a caster support, the inside of the connecting support 2 is rotatably provided with a caster body, and the outer wall of the connecting support 2 is provided with a foot brake for braking the caster body, so that the caster body can be installed on the bottom surface of different objects through the caster support, and different objects can be conveniently moved on the ground through the combined caster support and caster body.

[0028] According to the drawings Figures 1-2The connecting bracket 2 is equipped with a protective mechanism 3 on its exterior. This mechanism prevents the connecting bracket 2 from directly colliding with external objects and prevents linear impurities from becoming entangled on the outer wall of the connecting bracket 2's shaft. It also prevents the casters from carrying and accumulating external impurities inside the connecting bracket 2. The protective mechanism 3 includes a protective frame 31, which is fitted over the connecting bracket 2. The outer wall of the protective frame 31 has a rubber layer, reducing the impact force when the frame comes into contact with external objects, thus protecting the frame 31 and the connecting bracket 2 inside. A connector 32 is fixedly connected to the inner wall of the protective frame 31, with one end of the connector 32 connected to the outer wall of the connecting bracket 2. (Refer to the attached diagram.) Figure 2 The protective frame 31 is fixedly connected to the outer wall of the connecting bracket 2 via the connector 32. However, the specific type of connector 32 is not limited. For example, the connector 32 can be a matching sleeve and screw, allowing for convenient assembly and disassembly between the protective frame 31 and the connecting bracket 2 via the matching sleeve and screw. See attached figure. Figures 2-4 An elastic ring 33 is disposed on the inner surface of the opening at the bottom of the protective frame 31. A removal element 331 is disposed on the outer wall of the elastic ring 33. By adjusting the opening diameter of the elastic ring 33, the protective frame 31 can be stably fitted onto the outside of caster bodies of different diameters. The removal element 331 on the outer wall of the elastic ring 33 contacts the outer wall of the caster body. When the caster body rotates and carries impurities to the position of the removal element 331, the removal element 331 can prevent impurities from entering the interior of the protective frame 31, thereby preventing impurities from entering the interior of the connecting bracket 2. The connecting head 34 is fixedly connected to the bottom surface of the elastic ring 33, and the winding rod 37 is rotatably connected to the bottom surface of the protective frame 31. A connecting band 35, which controls the opening size of the elastic ring 33, is disposed between the connecting head 34 and the winding rod 37. The connecting band 35 is long. The protective frame 31 has a fixed angle and the connecting band 35 does not have the function of elastic extension. The bottom surface of the protective frame 31 is fixedly provided with a cover 36 that limits the rotation position of the winding rod 37. One side of the cover 36 is provided with a limiting hole 361 for limiting the movement of the connecting band 35. When adjusting the opening diameter of the elastic ring 33, by rotating the winding rod 37 in the forward direction, the winding rod 37 gradually winds the connecting band 35 around its outer wall, thereby causing the connector 34 to move closer to the cover 36 under the drive of the connecting band 35, so that the opening diameter of the elastic ring 33 is expanded. Conversely, when the winding rod 37 is rotated in the reverse direction, part of the connecting band 35 is in a loose state, thereby reducing the tension on the elastic ring 33, so that the elastic ring 33 tightens under its own elastic force, and the opening diameter of the elastic ring 33 becomes smaller.

[0029] See attached document Figures 4-5The inside of the cover 36 is provided with a locking assembly 4 for fixing between the winding rod 37 and the cover 36, the locking assembly 4 comprises a tooth ring 41 fixedly arranged on the outer wall of the winding rod 37, an inner tooth plate 42 limitingly and slidingly arranged in the inside of the cover 36 and a locking screw 43 rotatably arranged in the inside of the cover 36 for controlling the movement of the inner tooth plate 42, one end of the inner tooth plate 42 is clamped on the outer wall of the tooth ring 41, the bottom surface of the inner tooth plate 42 is fixedly connected with a bearing 44, and one end of the outer wall of the locking screw 43 is fixedly connected with the inner wall of the bearing 44, so that under the limitation of the bearing 44, when the locking screw 43 is rotated, the inner tooth plate 42 cannot move in the circumferential direction with the locking screw 43, and the inner tooth plate 42 can only move in the linear direction, the locking screw 43 is rotated to drive the inner tooth plate 42 to move towards the tooth ring 41, when the inner tooth plate 42 is clamped on the outer wall of the tooth ring 41, the winding rod 37 is fixed at the cover 36, and the winding length of the connecting belt 35 is fixed.
