[0002] The caster bracket makes the movement of equipment simple and fast, saving a large amount of manpower and material resources. By adjusting the height and angle of the caster, it can adapt to different ground conditions and movement requirements, improving the adaptability and flexibility of the equipment.

[0003] The caster brackets are basically fixed, resulting in a determined support height and being difficult to apply to various ground conditions and movement requirements. Therefore, we designed a caster bracket capable of multi-angle adjustment, which can adjust the height of the caster by adjusting the angle of the caster, enabling the caster to be applicable to various ground adjustments and movement requirements.

[0004] The purpose of the utility model is to provide a caster bracket capable of multi-angle adjustment, which has the advantage of being able to adjust the height of the caster by adjusting the angle of the caster, enabling the caster to be applicable to various ground adjustments and movement requirements, so as to solve the above-mentioned background technical problems.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A caster bracket capable of multi-angle adjustment, which includes a first bracket: A shaft rod is fixedly installed through the inner cavity of the first bracket, a runner bracket is rotatably connected to the surface of the shaft rod, a rotatable roller is installed in the inner cavity of the runner bracket, a pushing component is arranged between the runner bracket and the first bracket, the pushing component includes a threaded rod rotatably connected to the inner cavity of the first bracket, a threaded sleeve is threadedly connected to the surface of the threaded rod, a first connecting piece is fixedly connected to the bottom of the threaded sleeve, a push rod is rotatably connected to the inner cavity of the first connecting piece through a rotating shaft, a sleeve cover is welded to one side of the runner bracket, a second connecting piece is welded to the top of the sleeve cover, and the push rod is rotatably connected to the inner cavity of the second connecting piece through a rotating shaft.

[0006] Preferably, a rotatable mounting plate is installed on the top of the first bracket, and mounting holes are respectively opened at the four corners of the top of the mounting plate.

[0007] Preferably, two guide rods are horizontally and fixedly connected to the inner cavity of the first bracket, and the threaded sleeve is slidably connected to the surfaces of the two guide rods.

[0008] Preferably, a threaded hole adapted to the threaded rod is opened on the threaded sleeve.

[0009] Preferably, one end of the threaded rod penetrates to the outside of the first bracket and is fixedly installed with a hand wheel.

[0010] 1. The beneficial effects of the present utility model are as follows: By operating the rotation of the threaded rod, the threaded sleeve moves to the right. The threaded sleeve causes the push rod to rotate within the inner cavities of the connecting member 1 and the connecting member 2. The cover pushes the runner bracket to rotate downward on the surface of the shaft rod, so that the angle of the roller can be changed, and thus the support height of the roller can also be adjusted. That is, the adjustment of the height of the caster can be achieved by adjusting the angle of the caster, so that the caster can be adapted to various ground adjustment and movement requirements.

[0019] Hereinafter, embodiments of the multi-angle adjustable caster bracket of the present utility model will be described with reference to the drawings.

[0020] Figures 1-3Shown is a caster bracket that can be adjusted at multiple angles according to an embodiment of the present invention, which includes a first bracket 1. A rotatable mounting plate 6 is installed on the top of the first bracket 1. Mounting holes 7 are provided at the four corners of the top of the mounting plate 6. A shaft rod 2 is fixedly installed through the inner cavity of the first bracket 1. A rotating wheel frame 3 is rotatably connected to the surface of the shaft rod 2. A rotatable roller 4 is installed in the inner cavity of the rotating wheel frame 3. A pushing assembly 5 is provided between the rotating wheel frame 3 and the first bracket 1. The pushing assembly 5 includes a threaded rod 51 rotatably connected to the inner cavity of the first bracket 1. A threaded sleeve 52 is threadedly connected to the surface of the threaded rod 51. A first connecting member 53 is fixedly connected to the bottom of the threaded sleeve 52. A push rod 54 is rotatably connected to the inner cavity of the first connecting member 53 through a rotating shaft. A sleeve cover 55 is welded to one side of the rotating wheel frame 3. A second connecting member 56 is welded to the top of the sleeve cover 55. The inner cavity of the second connecting member 56 is rotatably connected to the push rod 54 through a rotating shaft. Two guide rods 57 are horizontally and fixedly connected to the inner cavity of the first bracket 1. The threaded sleeve 52 is slidably connected to the surfaces of the two guide rods 57. Through the arrangement of the guide rods 57, the threaded sleeve 52 will move on the surfaces of the guide rods 57 during the movement process, guiding and limiting the movement of the threaded sleeve 52, avoiding the rotation of the threaded sleeve 52 following the rotation of the threaded rod 51, and improving the stability of the movement of the threaded sleeve 52. A threaded hole 59 adapted to the threaded rod 51 is provided on the threaded sleeve 52. One end of the threaded rod 51 penetrates to the outside of the first bracket 1 and is fixedly installed with a handwheel 58. Through the arrangement of the handwheel 58, a force application point can be provided for the user to rotate the threaded rod 51, thereby facilitating the user to operate the rotation of the threaded rod 51.

[0021] Working principle: When the present invention is in use, the user operates the handwheel 58 to rotate, thereby driving the threaded rod 51 to rotate. Due to the thread, the threaded sleeve 52 moves to the right under the limitation of the guide rod 57. During the movement of the threaded sleeve 52, the push rod 54 rotates in the inner cavities of the first connecting member 53 and the second connecting member 56, pushing the sleeve cover 55 downward. The sleeve cover 55 then pushes the rotating wheel frame 3 to rotate on the surface of the shaft rod 2, so that the angle of the roller 4 is changed, and thus the supporting height of the roller 4 is also adjusted. By adjusting the angle of the caster, the height of the caster is adjusted, and the applicability is strong.

[0022] In summary: For this caster bracket that can be adjusted at multiple angles, by operating the rotation of the threaded rod 51, the threaded sleeve 52 moves to the right. The threaded sleeve 52 causes the push rod 54 to rotate in the inner cavities of the first connecting member 53 and the second connecting member 56. By pushing the rotating wheel frame 3 to rotate downward on the surface of the shaft rod 2 through the sleeve cover 55, the angle of the roller 4 is changed, and thus the supporting height of the roller 4 is also adjusted. That is, it can achieve the adjustment of the caster height by adjusting the angle of the caster, so that the caster can be suitable for various ground adjustment and movement requirements.
