Detailed Description

Referring to fig. 1-3, the utility model provides a novel figure-carrying four-wheel elastic platform, which comprises: work platform 1 and install the bearing structure in the work platform bottom, wherein:

the supporting structure comprises a guide part 2, a universal wheel 3 and a foot cup, wherein the guide part 2 is fixedly arranged on the operation platform 1; the foot cup is fixedly arranged on the guide part 2; the universal wheel 3 is located below the guide part 2 and is elastically assembled with the guide part 2 through the elastic component, and in a natural state, the bottom face of the universal wheel 3 is located below the foot cup, so that the foot cup is not in contact with the ground in the state, and when the operation platform 1 is compressed by the elastic component driven by the pressure, the foot cup moves downwards along with the operation platform to be in contact with the ground.

Specifically, the method comprises the following steps: the elastic component comprises a guide shaft 4 and a spring 5 sleeved on the guide shaft 4, the guide shaft 4 is axially movably mounted on the guide part 2, the guide shaft 4 is vertically arranged, a base 6 is arranged at the bottom of the guide shaft 4, and the universal wheel 3 is positioned below the base 6 and mounted on the base 6; one end of the spring 5 is connected to the guide 2 and the other end is connected to the base 6. When the operation platform 1 is pressed, the guide piece 2 is driven to move downwards, and then the spring 5 enters a compressed state, and the foot cup is contacted with the ground. And when the pressure disappears, the spring 5 resets to lift the operation platform 2 again, so that the foot cup enters the state of not contacting with the ground again.

Therefore, when no person steps on the platform, the elastic component is in a natural state, and the platform can move freely under the action of the universal wheels 3. After the personnel stepped on, elastic component got into compression state, and at this moment, the foot cup moved down and contact with ground to make universal wheel 3 can't remove again, make whole platform get into fixed state then, ensured personnel's safety. When the person comes down and the pressure disappears, the elastic component resets, the foot cup is separated from the ground again, and the platform can move again. The setting platform of the structure is of a pure mechanical structure, does not need electric drive, and is convenient to assemble and practical and reliable in structure. The device is greatly convenient for personnel to tread on the workbench to carry out work such as high-place operation, temporary placement of articles and the like.

In the embodiment, the guide part 2 is provided with a guide hole and a screw hole positioned at one side of the guide hole, a spring gland 7 fixed with the guide hole is arranged in the guide hole, and the spring gland 7 is provided with a central hole coaxial with the guide hole; the guide shaft 4 includes an upper shaft section 41 and a lower shaft section 42, and the outer diameter of the upper shaft section 41 is larger than the bore diameter of the central hole so that the upper shaft section 41 cannot pass through the central hole. The outer diameter of the lower shaft segment 42 is smaller than the bore diameter of the central bore so that the lower shaft segment 42 can pass through the central bore.

The guide shaft 4 is mounted in the guide bore so as to be axially movable, and has an upper shaft section 41 above the spring cover 7 and a lower shaft section 42 below the spring cover 7. So that the upper shaft section 41 can not pass through the central hole of the spring gland 7 after the platform is lifted, thereby preventing the guide shaft 4 from being pulled out of the guide hole.

The base 6 is detachably assembled on the lower shaft section 42 through bolts; one end of the spring 5 is abutted against the spring gland 7, and the other end of the spring is abutted against the base 6; when the base 6 is detached from the lower shaft section 42, the guide drawer 4 can be directly drawn out. The foot cup is in threaded connection with the screw hole through the connecting shaft 8, and the foot cup can be disassembled and assembled by screwing in and screwing out the connecting shaft 8.

From the above, the structure of the guide 2 is greatly convenient to assemble and disassemble, so that each part can be directly replaced when damaged.

Specifically, the method comprises the following steps: the guide 2 comprises a sleeve 21, a positioning sleeve 22 and a connecting sleeve 23; the sleeve 21 is vertically arranged, a guide hole is formed in an inner cavity of the sleeve, the end portion of the sleeve is provided with the connecting seat 9 integrally formed with the sleeve, the connecting seat 9 is fixed with the operation platform 1 through a threaded fastener, and the contact surface between the sleeve 21 and the operation platform 1 can be effectively increased through the arrangement mode of the structure. The positioning sleeve 22 is coaxially arranged below the sleeve 21; the connecting sleeve 23 is sleeved outside the sleeve 21, and one end of the connecting sleeve abuts against and is fixed to the connecting seat 9, and the other end of the connecting sleeve abuts against and is fixed to the positioning sleeve 22. One side of the connecting sleeve 23 is provided with a block part 231 fixed with the connecting sleeve, and the screw hole is positioned on the block part 231; the spring 5 is located inside the positioning sleeve 22.

In this embodiment, the number of the supporting assemblies is multiple, specifically four, and four supporting assemblies are arranged at the bottom of the working platform 1 in a matrix. So as to ensure the stability of the support.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
