Description

Technical Field

[0001] This utility model relates to the field of wallpaper technology, and in particular to an auxiliary device for wallpaper application in decoration. Background Technology

[0002] Wallpaper, also known as wall covering, is an interior decoration material used to cover walls. It is widely used in the interior decoration of residences, offices, hotels, and restaurants. The material is not limited to paper and also includes other materials. Usually, people apply wallpaper by hand without special tools, which is time-consuming and laborious. The wallpaper is easy to fall off because it is too tightly attached, and air bubbles may even remain between the wallpaper and the wall, affecting the appearance.

[0003] Chinese Patent No. CN217778220U discloses a wallpaper application auxiliary device for decoration, including a base plate. A support rod is fixedly connected to the top of the base plate. An adjusting block is connected to the support rod through a drive assembly. A telescopic rod is fixedly connected to the end of the adjusting block. A connecting block is fixedly connected to the end of the telescopic rod. A pressure roller is connected to the connecting block through a connecting assembly. The drive assembly includes a servo motor installed on the top of the support rod. A threaded rod is provided at the output end of the servo motor. The threaded rod is threadedly connected to the adjusting block. This utility model, by setting the connecting assembly and the pressure roller, allows the wallpaper to be quickly and fully adhered to the wall surface by the pressure of the pressure roller during wallpaper application, eliminating the need for manual pressing and making it more convenient and faster. It also ensures that no air bubbles remain in the wallpaper, greatly improving the wallpaper application efficiency and ensuring aesthetics.

[0004] However, in the above-mentioned solution, when applying wallpaper, the telescopic rod mechanically slides the pressure roller up and down, using vertical squeezing force to press the wallpaper. When the wallpaper surface is uneven or the wall surface has slight undulations, it will cause wrinkles or bubbles in the wallpaper. In addition, the length of the screw will limit the working range, especially when applying large areas of wallpaper, it is impossible to cover a long wall surface at once. If the screw is too long, it is inconvenient to operate and difficult to move. Therefore, a wallpaper application auxiliary device for decoration is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the technical problems of existing wallpapering methods that use vertical pressure to press the wallpaper down, resulting in wrinkles or air bubbles, and the limitation of the screw length on the working range, making it impossible to cover long wall areas at once when applying large areas of wallpaper, and the inconvenience and difficulty in moving if the screw is too long, this application provides a wallpapering auxiliary device for decoration.

[0006] This utility model proposes a wallpapering auxiliary device for decoration, including a handcart with locking rollers. The outer surface of the handcart is provided with an adjustment mechanism, which includes a spring and a sliding rod. The spring causes the sliding rod to return to its original position.

[0007] The outer surface of the trolley is provided with an auxiliary mechanism, which includes a pressure roller. The relative movement of the pressure roller flattens the wallpaper onto the wall.

[0008] Preferably, the adjustment mechanism further includes a hydraulic cylinder, which is fixedly installed on the upper surface of the handcart, and a movable frame is fixedly installed on one end of the piston rod of the hydraulic cylinder.

[0009] The above technical solution uses a hydraulic cylinder to fix the device to a handcart. The locking rollers on the handcart ensure the stability of the device and prevent displacement during wallpaper application. The piston rod of the hydraulic cylinder is fixed to a moving frame. The extension and retraction of the piston rod can raise and lower the moving frame to adjust the height of the auxiliary mechanism.

[0010] Preferably, the outer surface of the movable frame is slidably connected to the inner wall of the groove of the handcart, and the spring is fixedly installed on the inner wall of the handcart.

[0011] The above technical solution allows the mobile frame to be smoothly raised and lowered by sliding connection with the handcart. The handcart is fixedly installed with a spring, which in turn drives the slide rod fixedly installed with the other end of the spring to return to its original position.

[0012] Preferably, the slide rod is slidably inserted into the inner wall of the handcart, and the outer surface of the slide rod is fixedly installed to one end of the spring.

[0013] The above technical solution improves the trajectory of the slide rod by sliding it into the trolley, allowing it to move smoothly. The slide rod is fixedly installed with a spring, which can reset the slide rod after it rises. At the same time, after the moving frame rises, the cylinder on it slides into the inner wall of the cylindrical groove of the slide rod, so that the moving frame can continue to rise smoothly when it reaches or exceeds the original height of the trolley.

[0014] Preferably, the auxiliary mechanism further includes an electric push rod, which is fixedly installed on the outer surface of the movable frame, and a slider is fixedly installed at one end of the push rod.

[0015] The above technical solution involves fixing the electric push rod to the movable frame, and fixing the push rod to the slider. The extension and retraction of the push rod can drive the slider to move, so that the movement of the slider can drive the support frame to move through the connecting rod.

[0016] Preferably, the inner wall of the groove of the slider is slidably connected to the outer surface of the movable frame, and a connecting rod is rotatably connected to the outer surface of the slider, with one end of the connecting rod rotatably connected to a support frame.

[0017] The above technical solution provides a motion trajectory for the slider by slidingly connecting it to the moving frame. The slider is fixed without affecting its deflection by rotating it to the connecting rod. The connecting rod is also fixed without affecting its deflection by rotating it to the support frame, so that the movement of the slider can drive the support frame to move through the connecting rod.

[0018] Preferably, the support frame is slidably sleeved on the outer surface of the movable frame, and the outer surface of the support frame is rotatably connected to the outer surface of the pressure roller.

[0019] The above technical solution uses a sliding connection between the support frame and the movable frame to fix the wallpaper without affecting its movement. The support frame is rotatably connected to the pressure roller, which moves the pressure roller synchronously without affecting its rotation. This allows continuous and uniform pressure to be applied to the wallpaper, ensuring that the wallpaper adheres tightly to the wall.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting an adjustment mechanism to reset the slide bar, the locking rollers on the trolley ensure the stability of the device. The extension and retraction of the piston rod of the hydraulic cylinder can drive the moving frame to rise and fall. The slide bar is slidably connected to the trolley, improving the movement trajectory of the slide bar. The slide bar is fixedly installed with the spring, and the spring can reset the slide bar after it rises. At the same time, after the moving frame rises, the cylinder on it slides into the inner wall of the cylindrical groove of the slide bar, so that the moving frame can continue to rise smoothly when it rises to or exceeds the original height of the trolley. This solves the technical problem that the length of the screw limits the working range when applying wallpaper, especially when applying large areas of wallpaper, making it impossible to cover a long wall surface at once. If the screw is too long, it will be inconvenient to operate and difficult to move.

[0022] 2. By setting up an auxiliary mechanism, the wallpaper is smoothly adhered to the wall surface. The push rod of the electric push rod is fixedly installed with the slider. The extension and retraction of the push rod can drive the slider to move on the slidingly connected moving frame. The movement of the slider drives the support frame to move on the slidingly connected moving frame through the connecting rod. The support frame is rotatably connected to the pressure roller, driving the pressure roller to move synchronously without affecting its rotation, so as to apply continuous and uniform pressure to the wallpaper, ensuring that the wallpaper adheres tightly to the wall surface. This solves the technical problem that when wallpapering, the telescopic rod mechanically slides the pressure roller up and down, using vertical extrusion to press the wallpaper, which can cause wrinkles or bubbles in the wallpaper when the wallpaper surface is uneven or the wall surface has slight undulations.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-5 A wallpapering auxiliary device for decoration includes a handcart 1 with locking rollers. The outer surface of the handcart 1 is provided with an adjustment mechanism, which includes a spring 3 and a slide bar 4. The spring 3 causes the slide bar 4 to return to its original position.

[0031] To adjust the height of the auxiliary mechanism, the adjustment mechanism also includes a hydraulic cylinder 2. The hydraulic cylinder 2 is fixedly installed on the upper surface of the handcart 1. A movable frame 21 is fixedly installed at one end of the piston rod of the hydraulic cylinder 2. The hydraulic cylinder 2 is fixedly installed to the handcart 1, and the locking rollers equipped on the handcart 1 can ensure the stability of the device and prevent it from shifting during the wallpaper application process. The piston rod of the hydraulic cylinder 2 is fixedly installed to the movable frame 21. The extension and retraction of the piston rod of the hydraulic cylinder 2 can drive the movable frame 21 to rise and fall, so as to adjust the height of the auxiliary mechanism.

[0032] To ensure smooth lifting and lowering of the movable frame 21, the outer surface of the movable frame 21 is slidably connected to the inner wall of the groove of the handcart 1. The spring 3 is fixedly installed on the inner wall of the handcart 1. By sliding the movable frame 21 to the handcart 1, the movable frame 21 can be lifted and lowered smoothly. The spring 3 is fixedly installed to the handcart 1 to fix it so as to drive the slide rod 4, which is fixedly installed at the other end of the spring 3, to return to its original position.

[0033] To reset the slide bar 4, it is slidably inserted into the inner wall of the handcart 1. The outer surface of the slide bar 4 is fixedly installed with one end of the spring 3. By sliding the slide bar 4 into the handcart 1, the movement trajectory of the slide bar 4 is improved, allowing it to move smoothly. By fixing the slide bar 4 to the spring 3, the spring 3 can reset the slide bar 4 after it rises. At the same time, after the moving frame 21 rises, the cylinder on it slides into the inner wall of the cylindrical groove of the slide bar 4, so that the moving frame 21 can continue to rise smoothly when it rises to or exceeds the original height of the handcart 1.

[0034] By setting an adjustment mechanism to reset the slide bar 4, the locking rollers on the handcart 1 ensure the stability of the device. The extension and retraction of the piston rod of the hydraulic cylinder 2 can drive the moving frame 21 to rise and fall. The slide bar 4 is slidably inserted into the handcart 1 to improve the movement trajectory of the slide bar 4. The slide bar 4 is fixedly installed with the spring 3. After the slide bar 4 rises, the spring 3 can reset it. At the same time, after the moving frame 21 rises, the cylinder on it slides into the inner wall of the cylindrical groove of the slide bar 4, so that the moving frame 21 can continue to rise smoothly when it rises to or exceeds the original height of the handcart 1. This solves the technical problem that the length of the screw will limit the working range when applying wallpaper, especially when applying large areas of wallpaper, it is impossible to cover a long wall surface at once. If the length of the screw is too long, the operation will be inconvenient and the movement will be difficult.

[0035] In order to smoothly adhere the wallpaper to the wall, the outer surface of the trolley 1 is provided with an auxiliary mechanism, including a pressure roller 7. The relative movement of the pressure roller 7 smoothly adheres the wallpaper to the wall.

[0036] In order to move the slider 51, the auxiliary mechanism also includes an electric push rod 5. The electric push rod 5 is fixedly installed on the outer surface of the movable frame 21. The slider 51 is fixedly installed at one end of the push rod of the electric push rod 5. The electric push rod 5 is fixedly installed to the movable frame 21. The extension and retraction of the push rod can drive the slider 51 to move, so that the movement of the slider 51 drives the support frame 61 to move through the connecting rod 6.

[0037] The inner wall of the groove of the slider 51 is slidably connected to the outer surface of the movable frame 21. The outer surface of the slider 51 is rotatably connected to the connecting rod 6. One end of the connecting rod 6 is rotatably connected to the support frame 61. The slider 51 is slidably connected to the movable frame 21, which can provide a motion trajectory for the slider 51. The slider 51 is rotatably connected to the connecting rod 6, which fixes it without affecting its deflection. The connecting rod 6 is rotatably connected to the support frame 61, which fixes it without affecting its deflection, so that the movement of the slider 51 drives the support frame 61 to move through the connecting rod 6.

[0038] The support frame 61 is slidably sleeved on the outer surface of the movable frame 21. The outer surface of the support frame 61 is rotatably connected to the outer surface of the pressure roller 7. By slidably sleeved on the movable frame 21, the support frame 61 is fixed without affecting its movement. By rotatably connecting the support frame 61 to the pressure roller 7, the pressure roller 7 is driven to move synchronously without affecting its rotation, so that continuous and uniform pressure can be applied to the wallpaper to ensure that the wallpaper adheres tightly to the wall.

[0039] By setting up an auxiliary mechanism, the wallpaper is smoothly adhered to the wall surface. The push rod of the electric push rod 5 is fixedly installed with the slider 51. The extension and retraction of the push rod can drive the slider 51 to move on the slidingly connected moving frame 21. The movement of the slider 51 drives the support frame 61 to move on the slidingly connected moving frame 21 through the connecting rod 6. The support frame 61 is rotatably connected to the pressure roller 7, which drives the pressure roller 7 to move synchronously without affecting its rotation, so as to apply continuous and uniform pressure to the wallpaper and ensure that the wallpaper adheres tightly to the wall surface. This solves the technical problem that when wallpapering, the telescopic rod mechanically slides the pressure roller 7 up and down to press the wallpaper with vertical extrusion force, which can cause wrinkles or bubbles in the wallpaper when the wallpaper surface is uneven or the wall surface has slight undulations.

[0040] Working principle: When wallpaper needs to be flat and adhered to the wall, the worker moves the handcart 1 to the designated position, so that the pressure roller 7 contacts the wallpaper and applies a certain pressure to ensure that the wallpaper is flat and tightly adhered to the wall. The locking rollers equipped on the handcart 1 can ensure the stability of the device and prevent it from shifting during the wallpaper application process. At the same time, the electric push rod 5 is activated. The extension of the push rod drives the slider 51, which is fixedly installed thereto, to move on the slidingly connected moving frame 21. Since the connecting rod 6 is rotatably connected to the slider 51 and the support frame 61, the movement of the slider 51 causes the connecting rod 6 to deflect. Thus, the connecting rod 6 drives the support frame 61 to move relative to the slidingly connected moving frame 21. The pressure roller 7, which is rotatably connected to the support frame 61, applies continuous and uniform pressure to the wallpaper to ensure that the wallpaper adheres tightly to the wall.

[0041] When the fitting height needs to be adjusted, the hydraulic cylinder 2 is activated. The piston rod of the hydraulic cylinder 2 extends and drives the movable frame 21, which is fixedly installed thereto, to move on the slidably connected handcart 1. When it moves to a certain height, the cylinder on the movable frame 21 slides into the cylindrical groove on the surface of the slide rod 4, which is slidably inserted into the handcart 1, providing a guiding function for the rise of the movable frame 21. The spring 3, which is fixedly installed with the handcart 1 and the slide rod 4, resets the slide rod 4 when needed.

[0042] 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.
