[0001] This utility model relates to the field of building decoration, specifically a wall cleaning device for building decoration. Background Technology

[0002] Decoration, also known as interior design or renovation, refers to a set of construction and design plans carried out in a certain area and scope, including water and electricity construction, walls, floors, ceilings, landscaping, etc., based on certain design concepts and aesthetic rules. Among them, the wall planer is one of the devices used to clean the wall. The wall planer consists of an outer shell and a motor and a planing roller installed inside the outer shell. The motor drives the planing roller to rotate and clean the wall surface.

[0003] In the prior art, when decorating a room, if there is old plaster on the walls, it is necessary to clean the old plaster before repainting the new walls. Workers use scrapers or wall planers to clean the plaster. However, the walls of a room are generally about 3 meters high, and workers need to use ladders or other tools to clean the plaster at higher heights, which poses certain safety hazards. Based on this, this utility model proposes a wall cleaning device for building decoration. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 In this embodiment of the utility model, a wall cleaning device for building decoration includes a movable base 1 with universal wheels installed at the bottom, a pole 2 fixed to the top of the movable base 1, a wall planer 3 for cleaning the wall surface is provided on the side of the pole 2, and a limiting mechanism 4 provided on the pole 2 and the wall planer 3 for providing a limit for the connection of the wall planer 3.

[0025] The limiting mechanism 4 includes a transmission unit and a limiting unit;

[0026] The transmission unit is used to provide power for the up-and-down movement of the wall planer 3;

[0027] The limiting unit is used to provide a limit for the connection between the wall planer 3 and the transmission unit;

[0028] The transmission unit includes a drive motor 401 and a two-way lead screw 402;

[0029] The drive motor 401 is installed at the top of the movable base 1 and located below the bottom of the upright 2. The drive motor 401 is used to provide rotational power to the bidirectional lead screw 402 connected to the output end. The bidirectional lead screw 402 is connected to the output end of the drive motor 401. The movable block 403 is provided with balls that mesh with the bidirectional lead screw 402.

[0030] The limiting unit includes a movable block 403, a docking block 404, a movable rod 405, a transmission rod 406, a limiting block 407, and a spring 408;

[0031] The movable block 403 engages with the inner cavity of a threaded groove of the double-acting screw 402 through internal ball bearings. The end of the movable block 403 with the groove extends to the outside of the upright 2. The movable block 403 provides space for the docking of the docking block 404. The docking block 404 is fixed to the outer wall of the wall planer 3. The docking block 404 provides support for the connection between the wall planer 3 and the movable block 403.

[0032] The movable rod 405 is axially slidably mounted on the base plate of the movable block 403, and the other end of the movable rod 405 extends to the outside of the upright 2 away from the planer 3. The movable rod 405 is used to drive the transmission rod 406, which is rotatably connected at the end, to push the limiting block 407 to move laterally. The two ends of the transmission rod 406 are rotatably connected to the outer walls of the movable rod 405 and the limiting block 407, respectively. The limiting block 407 is laterally slidably mounted on the inner wall of the slot end of the movable block 403, and one end of the inclined surface extends into the slot of the movable block 403. The two ends of the spring 408 are respectively engaged with the inner wall of the movable block 403 and the outer wall of the protrusion of the movable rod 405. The spring 408 is used to provide a restoring force for the movable rod 405 after it has moved.

[0033] In this embodiment: With this structure, when cleaning high-level wall plaster is required, the vertical pin that limits the movable rod 405 can be removed first. Then, the wall planer 3 with the connecting block 404 is connected to the end slot of the movable block 403, allowing the connecting block 404 to insert into the inner cavity of the end slot of the movable block 403. Simultaneously, as the connecting block 404 enters the slot of the movable block 403, the end of the connecting block 404 contacts the inclined force-bearing surface of the limiting block 407, providing an axial moving thrust to the limiting block 407, thus limiting the movement. Block 407 pushes movable rod 405 axially through transmission rod 406, so that movable rod 405 applies compressive force to spring 408. When the end of limiting block 407 is aligned with the limiting groove on the outer wall of docking block 404, movable rod 405 will reset under the action of spring 408. At the same time as movable rod 405 resets, it drives limiting block 407 to move laterally into the limiting groove of docking block 404 through transmission rod 406, thus completing the connection and limiting of upright rod 2 and movable block 403. At this time, the external power supply of movable base 1 can be connected.

[0034] Next, the electrically connected drive motor 401 and wall planer 3 are started. The operation of the wall planer 3 will drive the cleaning rod connected at the bottom to rotate and clean the wall surface (it should be noted that the wall planer 3 is a common type of electric wall planer on the market, such as the BX-BQJ-3B type wall planer, therefore, the internal structure and operating principle of the wall planer 3 will not be described in detail here). The operation of the drive motor 401 will drive the bidirectional lead screw 402 connected to the output end to rotate, so that the bidirectional lead screw 402 will give the movable block 403 a threaded pressing force, so that the movable block 403 moves up and down along the two opposite thread grooves of the bidirectional lead screw 402 through the meshing slider. During the up and down movement of the movable block 403, the corrugated pipes connected at the upper and lower ends will move simultaneously, thereby pushing the wall planer 3 to move up and down to clean the wall surface. It should be noted that the corrugated pipe is used to protect the bidirectional lead screw 402 to prevent external dust and other debris from obstructing the up and down movement of the movable block 403, and the movable rod 405 and the bidirectional lead screw 402 are intersected in a cross shape.

[0035] Please refer to this carefully. Figures 1-4 The end of the limiting block 407 is inclined near the side of the docking block 404. The inner cavity groove of the movable block 403 matches the outer wall of the docking block 404. The inner wall of the movable block 403 is formed with a movable groove for the lateral movement of the limiting block 407 and the axial movement of the movable rod 405. The outer wall of the limiting block 407 is formed with a limiting groove for the insertion of the limiting block 407.

[0036] In this embodiment: With this structure, under the action of the inclined force-bearing surface of the limiting block 407, when the docking block 404 is inserted into the inner cavity of the movable block 403, the docking block 404 will exert a squeezing force on the inclined force-bearing surface of the limiting block 407 to push the limiting block 407 to move laterally, so that the limiting block 407 is aligned with the limiting groove on the outer wall of the docking block 404, and the docking block 404 and the movable block 403 are automatically engaged.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
