Description

Technical Field

[0001] This utility model belongs to the field of wall repair technology, and in particular relates to a device for repairing the roof and walls of old houses during renovation. Background Technology

[0002] Roof and wall renovation in house renovation refers to the process of repairing, renovating, upgrading or beautifying the roof and walls of a house, with the aim of improving the structural stability, appearance and comfort of the house.

[0003] When dealing with walls where the original plaster has peeled, delaminated, or flaked, and the surface is no longer smooth, it is usually necessary to use a scraper to remove the original plaster in order to cover it with a new wall later. However, when using a scraper to remove the original plaster, the vibration generated during the operation of the device and the reaction force when the scraper comes into contact with the plaster may cause the device to move, making it difficult for the scraper to adhere to the wall surface, thus affecting the removal effect of the original plaster. Utility Model Content

[0004] The purpose of this utility model is to provide a roof and wall repair device for the renovation of old houses. By rotating the knob clockwise, the bottom of the anti-slip plate contacts the ground, which increases the friction between the device and the ground. This solves the problem that when the device moves, the scraper is difficult to adhere to the wall, thus affecting the removal effect of the original wall paint.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a roof and wall repair device for renovating old houses, including a base plate, a self-locking universal wheel fixedly connected to the bottom of the base plate, a handle fixedly connected to the top of the base plate, an anti-slip mechanism provided on the base plate, a moving mechanism provided above the base plate, and a cleaning mechanism provided on the moving mechanism.

[0007] The anti-slip mechanism includes a first groove formed on the top of the base plate. A bidirectional threaded rod is rotatably connected inside the first groove. One end of the bidirectional threaded rod passes through the outer wall of the base plate and extends outward. A knob is fixedly connected to the end of the bidirectional threaded rod away from the base plate. A slider is threadedly connected to the outer wall of the bidirectional threaded rod. A connecting rod is rotatably connected to the bottom of the slider. An anti-slip plate is rotatably connected to the end of the connecting rod away from the slider. A first limiting rod is fixedly connected to the side of the anti-slip plate near the connecting rod. A first fixing plate is fixedly connected to the end of the first limiting rod away from the anti-slip plate.

[0008] Furthermore, the slider is slidably connected inside the first groove, and the outer wall of the first limiting rod is slidably connected inside the base plate.

[0009] Furthermore, the moving mechanism includes a mounting bracket fixedly connected to the top of the base plate, the mounting bracket having a second sliding groove, and a sliding rod fixedly connected inside the second sliding groove.

[0010] Furthermore, a motor is fixedly connected to the top of the mounting bracket, the output end of the motor is rotatably connected inside the mounting bracket, and the output end of the motor is fixedly connected to a first threaded rod via a coupling.

[0011] Furthermore, the end of the first threaded rod away from the motor is rotatably connected to the top of the base plate, and a mounting plate is threadedly connected to the outer wall of the first threaded rod. The inner wall of the mounting plate is slidably connected to the outer wall of the second slide groove.

[0012] Furthermore, the clearing mechanism includes a second limiting rod slidably connected inside the mounting plate. The end of the second limiting rod near the handle is fixedly connected to a second fixing plate.

[0013] Furthermore, a second threaded rod is threadedly connected inside the second fixed plate, and a rotating rod is fixedly connected to one end of the second threaded rod near the self-locking caster wheel.

[0014] Furthermore, the end of the second threaded rod away from the rotating rod is rotatably connected to the outer wall of the mounting plate, and the end of the second limiting rod away from the second fixed plate is fixedly connected to a scraper.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a clockwise rotating knob to rotate a bidirectional threaded rod. The clockwise rotation of the bidirectional threaded rod causes the two sliders to move closer together. The sliders move the top of the connecting rod, while the bottom of the connecting rod pushes the anti-slip plate down. The anti-slip plate moves along with the first limit rod, which can effectively improve the stability of the anti-slip plate when it descends, so that the bottom of the anti-slip plate contacts the ground, increasing the friction between the device and the ground. This effectively prevents the device from moving due to vibrations generated during operation, thus affecting its wall plaster removal effect.

[0017] 2. This utility model involves rotating the rotating rod clockwise, which drives the second threaded rod to rotate. The clockwise rotation of the second threaded rod causes the second fixed plate to move towards the mounting plate. The second fixed plate drives the second limiting rod to move, and the movement of the second limiting rod pushes the scraper forward, thereby allowing the scraper to fit against the wall surface to accommodate wall plaster of different thicknesses.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-5As shown, this utility model is a roof and wall repair device for old house renovation, including a base plate 1, a self-locking universal wheel 11 fixedly connected to the bottom of the base plate 1, a handle 12 fixedly connected to the top of the base plate 1, pushing the handle 12 to push the device to the vicinity of the wall, an anti-slip mechanism 2 is provided on the base plate 1, a moving mechanism 3 is provided above the base plate 1, and a cleaning mechanism 4 is provided on the moving mechanism 3.

[0029] The anti-slip mechanism 2 includes a first groove 201 formed on the top of the base plate 1. A bidirectional threaded rod 202 is rotatably connected inside the first groove 201. One end of the bidirectional threaded rod 202 passes through the outer wall of the base plate 1 and extends outward. A knob 203 is fixedly connected to the end of the bidirectional threaded rod 202 away from the base plate 1. Rotating the knob 203 clockwise causes the bidirectional threaded rod 202 to rotate. A slider 204 is threadedly connected to the outer wall of the bidirectional threaded rod 202. Clockwise rotation of the bidirectional threaded rod 202 causes the two sliders 204 to move closer together. A connecting rod 205 is rotatably connected to the bottom of the sliders 204. The sliders 204 cause the top end of the connecting rod 205 to move, and the end of the connecting rod 205 away from the sliders 204 rotates. The device is connected to an anti-slip plate 206, and the bottom end of the connecting rod 205 pushes the anti-slip plate 206 to descend. A first limiting rod 207 is fixedly connected to the side of the anti-slip plate 206 near the connecting rod 205. The movement of the anti-slip plate 206 with the first limiting rod 207 can effectively improve the stability of the anti-slip plate 206 when it descends, so that the bottom of the anti-slip plate 206 contacts the ground, effectively preventing the device from moving due to vibration generated during operation, thereby affecting its wall removal effect. A first fixing plate 208 is fixedly connected to the end of the first limiting rod 207 away from the anti-slip plate 206. The slider 204 is slidably connected inside the first slide groove 201, and the outer wall of the first limiting rod 207 is slidably connected inside the base plate 1.

[0030] The moving mechanism 3 includes a mounting frame 301 fixedly connected to the top of the base plate 1. The mounting frame 301 has a second slide groove 302. A slide rod 303 is fixedly connected inside the second slide groove 302. A motor 304 is fixedly connected to the top of the mounting frame 301. When the motor 304 is started clockwise, the motor 304 drives the first threaded rod 305 to rotate. The output end of the motor 304 is rotatably connected to the inside of the mounting frame 301. The output end of the motor 304 is fixedly connected to the first threaded rod 305 through a coupling. When the first threaded rod 305 rotates clockwise, the mounting plate 306 will rise along the slide rod 303. The end of the first threaded rod 305 away from the motor 304 is rotatably connected to the top of the base plate 1. The mounting plate 306 is threadedly connected to the outer wall of the first threaded rod 305. When the mounting plate 306 moves to the top of the mounting frame 301, the motor 304 is rotated in the opposite direction, thereby moving the mounting plate 306 up and down, which can effectively remove the wall plaster. The inner wall of the mounting plate 306 is slidably connected to the outer wall of the second slide groove 302.

[0031] The cleaning mechanism 4 includes a second limiting rod 401 slidably connected inside the mounting plate 306. A second fixing plate 402 is fixedly connected to one end of the second limiting rod 401 near the handle 12. The second fixing plate 402 drives the second limiting rod 401 to move. A second threaded rod 403 is threadedly connected inside the second fixing plate 402. Clockwise rotation of the second threaded rod 403 causes the second fixing plate 402 to move towards the mounting plate 306. A rotating rod 404 is fixedly connected to one end of the second threaded rod 403 near the self-locking caster 11. Clockwise rotation of the rotating rod 404 causes the second threaded rod 403 to rotate. The end of the second threaded rod 403 away from the rotating rod 404 is rotatably connected to the outer wall of the mounting plate 306. A scraper 405 is fixedly connected to one end of the second limiting rod 401 away from the second fixing plate 402. Movement of the second limiting rod 401 pushes the scraper 405 forward, allowing the scraper 405 to fit against the wall surface, thus adapting to wall plaster of different thicknesses.

[0032] One specific application of this embodiment is:

[0033] In use, push handle 12 to bring the device close to the wall, then rotate knob 203 clockwise. Knob 203 drives the bidirectional threaded rod 202 to rotate. The clockwise rotation of the bidirectional threaded rod 202 causes the two sliders 204 to move closer together. The sliders 204 drive the top of the connecting rod 205 to move, while the bottom of the connecting rod 205 pushes the anti-slip plate 206 down. The anti-slip plate 206 moves with the first limit rod 207, which can effectively improve the stability of the anti-slip plate 206 when it descends, so that the bottom of the anti-slip plate 206 contacts the ground, increasing the friction between the device and the ground, and effectively preventing the device from moving due to vibrations generated during operation, thus affecting its wall plaster removal effect. Then, rotate the rotating rod 404 clockwise, which drives the second threaded rod 40 3. Rotation: The clockwise rotation of the second threaded rod 403 causes the second fixed plate 402 to move towards the mounting plate 306. The second fixed plate 402 drives the second limiting rod 401 to move, which in turn pushes the scraper 405 forward, allowing the scraper 405 to fit against the wall surface to accommodate different thicknesses of wall plaster. Then, the motor 304 is started clockwise, which drives the first threaded rod 305 to rotate. The clockwise rotation of the first threaded rod 305 causes the mounting plate 306 to rise along the slide rod 303. When the mounting plate 306 moves to the top of the mounting bracket 301, the motor 304 is rotated in the opposite direction, causing the mounting plate 306 to move up and down. The mounting plate 306 drives the cleaning mechanism 4 to move up and down, effectively removing the wall plaster.
