Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, a movable operation scaffold comprises a scaffold 1 and a working plate 2, wherein a wheel body 3 is arranged at the bottom of the scaffold 1, and the working plate 2 is slidably connected with the scaffold 1 and can move up and down.

The scaffold 1 is provided with supporting legs 4, the supporting legs 4 are connected with the working flat plate 2 through connecting rods 5, and two ends of each connecting rod 5 are fixedly connected or hinged with the supporting legs 4 and the working flat plate 2.

When the device is used, after an operator stands on the working flat plate 2, the working flat plate 2 moves downwards under the action of the weight of the operator, and the downward movement of the working flat plate 2 can drive the supporting legs 4 to move to be in contact with the ground, so that the device has the function of supporting and fixing, prevents random movement and provides resistance. When the operator gets off the work plate 2, the support legs 4 are subjected to a reduced pressure, at which time the scaffold 1 can be moved to the desired position.

Further, in order to prevent unnecessary interference between the support legs 4 and the ground during the movement, a support plate 6 connected to the work plate 2 is fixed to the scaffold 1, and a plurality of springs 7 are provided between the support plate 6 and the work plate; the spring 7 is preferably a cylindrical spring 7.

When an operator stands on the work flat plate 2, the work flat plate moves downwards and compresses the spring 7, so that the spring 7 generates elastic potential energy; when an operator gets down from the work flat plate 2, the spring 7 releases elastic potential energy to realize the upward movement of the work flat plate 2 and drive the supporting legs 4 to correspondingly move upwards to generate intervals with the ground, so that interference with the ground in the moving process is avoided.

Further, various structures may be adopted to realize sliding connection, for example, a slide block 8 connected with the scaffold 1 is fixed on the working flat plate 2, the slide block 8 is slidably connected with the upright rod portion of the scaffold 1, and a corresponding through hole is formed in the slide block 8.

Further, the above supporting leg is preferably provided with the following structure: the scaffold comprises a connecting sleeve 9 and a supporting rod 10, wherein the connecting sleeve 9 is in sliding connection with the scaffold 1, and the scaffold 1 is provided with a corresponding upright post 11; one end of the supporting rod 10 is fixedly connected with the connecting sleeve 9; the connecting rod 5 is fixedly connected or hinged with the connecting sleeve 9 or the supporting rod 10.

With the above structure, after the working plate 2 moves down, the connecting sleeve 9 can be driven by the connecting rod 5 to slide along the upright post 11, and the other end of the supporting rod 10 contacts (butts against) the ground.

Further, in order to achieve better contact with the ground when the ground is not even, corresponding resistance is provided; the movable support leg 12 is in sliding connection with the support rod 10, a support spring 13 is sleeved on the movable support leg 12, and two ends of the support spring 13 are respectively propped against the movable support leg 12 and the support rod 10; foot pads 14 are fixedly connected to the ends of the movable support legs 12.

When the ground is uneven, after the foot pad 14 is contacted with the ground, the foot pad drives the movable supporting legs to move and compress the spring 7, so that the foot pad 14 can be better contacted with the ground, and the elastic contact is realized.

Further, the above-mentioned foot pad 14 is preferably a rubber foot pad 14.

Furthermore, the wheel body 3 adopts universal wheels, and the installation seat of the universal wheels is fixedly connected with the bottom of the scaffold 1.

Further, in order to prevent the movable supporting leg 12 from being protruded, a fixing nut 15 is screwed to protrude from the supporting rod 10 at the top end of the movable supporting leg 12, and the escape thereof is restricted by the fixing nut 15. When in installation, the supporting spring 13 is sleeved on the movable supporting leg 12, and then the top end of the movable supporting leg 12 penetrates through the supporting rod 10 to extend out, and then the fixing nut 15 is screwed.

The preferred embodiments of the present utility model have been described in detail, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model, and the various changes are included in the scope of the present utility model.
