Description

Technical Field

[0001] The utility model relates to the technical field of casters, and more specifically, to a universal shock-absorbing caster module capable of electric lifting. Background Art

[0002] Casters are a general term, including movable casters, fixed casters and movable casters with brakes. The specific type depends on the actual situation. They can be installed on the bottom of trolleys and some equipment or devices that need to be moved to facilitate movement.

[0003] The current casters have poor shock absorption effect. When passing over a ground with a height difference, the casters vibrate and transmit the vibration to the handling equipment, causing impact and damage to the items.

[0004] For example, a Chinese patent with authorization announcement number CN216969209U discloses a shock-absorbing universal caster. The structure achieves shock absorption through the elasticity of elastic steel sheets and support pads. When the road surface is bumpy, the rubber pads provide further shock absorption to ensure the shock absorption effect of the universal caster. At the same time, the centering effect of the centering socket and the rubber pad buffers the eccentric load force on the mounting pin at the bottom of the mounting seat.

[0005] However, when this structure is actually used, the disadvantages of the load-bearing casters currently on the market mainly include relatively low load-bearing capacity and stability, which may not be suitable for occasions that need to withstand greater weight and pressure. In addition, the disadvantages of load-bearing casters also include slightly insufficient torsional rigidity and load-bearing capacity, which may limit its use in certain specific application scenarios. Moreover, the casters on the market are all pure mechanical casters with a single structure, which are difficult to be electrically lifted and adjusted, and have a limited scope of application. In view of this, the utility model proposes a universal shock-absorbing caster module that can be electrically lifted. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a universal shock-absorbing caster module capable of electric lifting to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a universal shock-absorbing caster module that can be electrically lifted and lowered, comprising an outer shell, a retaining frame is provided at the bottom of the outer shell, an inner bracket is slidingly provided inside the retaining frame, a caster body is rotatably installed inside the inner bracket, a slew bearing is provided between the retaining frame and the outer shell, and the retaining frame and the outer shell are rotatably connected via the slew bearing.

[0008] In order to realize electric lifting and adjustment of the caster body, preferably, an electric lifting structure is provided inside the shell, and the electric lifting structure includes an electric push rod, which is installed inside the shell, and the output end of the electric push rod extends to the inside of the retaining frame and is connected to the inner bracket, the two inner walls of the retaining frame are fixedly installed with guide rails, the surface of the inner bracket is fixedly installed with a slider, the slider is slidably connected on the guide rail, the top end of the electric push rod is connected to the first shell by a screw, and the output end of the electric push rod is connected to the inner bracket by a screw.

[0009] In order to facilitate the disassembly and assembly of the first shell and the second shell, preferably, the outer shell includes a first shell and a second shell, the second shell is arranged on one side of the first shell, and screws are arranged at the connection between the first shell and the second shell, and the first shell and the second shell are detachably connected by the screws.

[0010] In order to improve the shock-absorbing effect of the entire universal shock-absorbing caster module, preferably, shock-absorbing frames are fixedly provided on both outer walls of the first shell, and two damping shock absorbers are installed inside the shock-absorbing frames.

[0011] In order to achieve an anti-slip effect and at the same time, to provide good protection for the caster body, preferably, the outer portion of the caster body is provided with a polyurethane tire made of rubber material.

[0012] Technical effects and advantages of the utility model:

[0013] 1. By setting up an electric lifting structure, the electric push rod is extended and retracted to drive the inner bracket to slide up and down inside the retaining frame, and the slider slides on the guide rail to ensure the stability of the inner bracket when adjusting up and down. During the process of adjusting the inner bracket up and down, the caster body can be driven to adjust up and down, thereby achieving the purpose of electric lifting, which can drive the entire vehicle body or equipment connected to the universal shock-absorbing caster module to lift, thereby improving the use effect and diversifying the use.

[0014] 2. By arranging a slewing bearing between the retaining frame and the outer shell and rotating through the slewing bearing, the caster body can be adjusted in a universal direction, thereby improving the flexibility of use. At the same time, the universal shock-absorbing caster module is equipped with a shock-absorbing frame and a damping shock absorber, which can absorb and disperse the impact force, protect the equipment and the caster module itself from damage, and improve the service life, and has a good shock-absorbing effect.

[0015] To sum up, the casters of the present application have their own lifting effect, breaking the traditional pure mechanical caster style and enriching the types of casters. For equipment that needs to be lifted, only electric lifting universal shock-absorbing casters need to be used, which can simplify the structure of the entire equipment and make it more convenient and flexible. Moreover, the electric lifting universal shock-absorbing casters use slewing bearings with super large load-bearing capacity and are more durable. BRIEF DESCRIPTION OF THE DRAWINGS
