DETAILED DESCRIPTION

[0025] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0026] This embodiment provides a floor lifting device, the structure of which is as follows: Figure 1 As shown, it mainly includes a connecting plate 1, a column 2, a universal wheel 3, a fixing seat 4, an adjustment component 5, a base plate 6, a suction cup 7, an air pump 8, a handle 9, a cleaning component 10 and a guide rod 12.

[0027] Four columns 2 are fixedly connected to the bottom of the connecting plate 1, and a universal wheel 3 is fixedly connected to the bottom of each column 2. A fixing seat 4 is fixedly connected to one side of the connecting plate 1, and an adjustment component 5 is arranged inside the fixing seat 4. The bottom end of the adjustment component 5 passes through the bottom of the fixing seat 4 and is fixedly connected to the bottom plate 6. The bottom plate 6 is controlled by the adjustment component 5 to move vertically.

[0028] The top of the bottom plate 6 is fixedly connected with two symmetrically arranged guide rods 12, and the guide rods 12 are slidably inserted into the bottom of the fixing seat 4, so that the bottom plate 6 is slidably connected with the bottom of the fixing seat 4 and the bottom plate 6 cannot rotate.

[0029] The top of the bottom plate 6 is fixedly connected with an air pump 8, and a plurality of suction cups 7 are arranged at the bottom of the bottom plate 6. The output end of the air pump 8 is connected to the suction cups 7, and the air pump 8 is used to perform a vacuum operation on the suction cups 7. The top of the connecting plate 1 is fixedly connected with a cleaning assembly 10 and two symmetrically arranged handles 9, and the cleaning assembly 10 is used to clean the ground. The lower section of the cleaning assembly 10 is connected to the side wall of the bottom plate 6.

[0030] When working, the device can be moved by the universal wheel 3. After the device is moved to the specified position, the adjustment component 5 is operated to control the movement of the base plate 6. At the same time, the air pump 8 is started to vacuum the suction cup 7, so that the base plate 6 is adsorbed on the floor, and then the base plate 6 is moved upward to lift the floor. After the floor is lifted, the ground can be cleaned by the cleaning component 10.

[0031] like Figure 2 As shown, the adjustment assembly 5 includes a threaded barrel 501, a worm wheel 502, a worm 503 and a screw 504. Among them, the top of the fixed seat 4 is fixedly connected with a bearing, and the threaded barrel 501 passes through the central hole of the fixed seat 4 through the bearing and can stably rotate inside the fixed seat 4. The middle section of the threaded barrel 501 is fixedly connected to the outside with a worm wheel 502, and the worm 503 is rotatably connected to the inside of the fixed seat 4. The worm 503 is meshed with the worm wheel 502, and the screw 504 is connected to the inside of the bottom end of the threaded barrel 501 through a thread, and is fixedly connected to the top of the bottom plate 6. The outer end of the worm 503 extends to the outside of the fixed seat 4 and is fixedly connected to the operating rod 11.

[0032] During operation, the worm 503 is rotated by the operating rod 11, and the meshing between the worm 503 and the worm wheel 502 can drive the threaded barrel 501 to rotate. The threaded barrel 501 is threadedly matched with the screw 504. Since the screw 504 cannot rotate, when the threaded barrel 501 rotates, the screw 504 can move in the vertical direction. Therefore, by controlling the rotation direction of the worm 503, the vertical movement direction of the base plate 6 can be controlled.

[0033] like Figure 3 As shown, the cleaning assembly 10 includes a fan 1001, a connecting pipe 1002, a fixing plate 1003, a telescopic rod 1004 and a guide wind box 1005. The fan 1001 is fixedly connected to the top of the connecting plate 1, the connecting pipe 1002 is connected to the output end of the fan 1001, the fixing plate 1003 is fixedly connected to the side wall of the bottom plate 6, the telescopic rod 1004 is fixedly connected to the bottom of the fixing plate 1003, and the guide wind box 1005 is fixedly connected to the bottom of the telescopic rod 1004.

[0034] During operation, after the floor is lifted, the fan 1001 is started, and air is blown through the connecting pipe 1002, and then guided and blown out through the guide air box 1005, so as to blow away the garbage under the lifted floor, making it convenient for the staff to place things under the floor, and through the setting of the telescopic rod 1004, the bottom plate 6 can be in any position, and the guide air box 1005 can always be close to the ground, which is convenient for cleaning.

[0035] like Figure 4As shown, the bottom of the guide air box 1005 is fixedly connected to two separately arranged snap-in plates 13, and a roller 14 is rotatably connected between the two snap-in plates 13 to reduce the friction between the guide air box 1005 and the ground during operation and facilitate movement.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
