Description

Technical Field

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

[0002] Wall plastering refers to applying plaster to a wall surface. After plastering, workers need to smooth and level the surface. Overall, it provides functions such as moisture resistance, weathering prevention, and heat insulation, protecting the building walls from erosion by wind, rain, and snow. Currently, workers are using a plaster roller to smooth the wall surface during the plastering process.

[0003] Patent application number 202322641203.6 discloses an indoor building wall paint smoothing device. It is equipped with fixing holes, locking bolts, scrapers, guide plates, etc. The scraper is in contact with the paint roller to scrape off the protrusions formed by the paint on the surface of the paint roller, thereby ensuring the smoothing effect. At the same time, the guide plate catches the excess paint. The paint flows into the installation frame and is absorbed by the absorbent sponge in the collection box, thereby preventing excess paint from dripping down the paint roller and staining the construction workers, reducing waste and pollution.

[0004] Patent application number 202223486590.2 discloses an environmentally friendly wall smoothing device for buildings. Under the action of the limiting structure, the angle of the mounting plate and scraper can be adjusted without the need for the staff to change positions, reducing the intensity of the smoothing operation. At the same time, it can smooth the wall surface at different angles, improving practicality and reducing the limitations of use.

[0005] However, the smoothing devices mentioned above all rely on manual hand-held pressure applied to the wall surface. During the wall smoothing process, different pressures are applied to different locations, which can lead to uneven overall flatness of the wall surface. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rolling device for interior wall decoration. It uses a carriage to constrain the roller head, allowing the roller head to apply constant pressure to the wall surface, resulting in a wall surface with good flatness.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rolling device for interior wall decoration, comprising a main slide and a roller head. The bottom end of the main slide is detachably equipped with a base, and the top end of the main slide is equipped with an electric push rod that can be tightly supported against the top wall. The movable end of the electric push rod is fixed with a soft pad. A slider that moves vertically is slidably installed inside the main slide. One end of the slider is rotatably equipped with a push-pull rod, and the other end is equipped with a pressure-applying component that adjusts the degree of contact between the roller head and the side wall of the wall.

[0008] Preferably, the pressure-applying component includes a support plate symmetrically fixed to the end of the slider, and a lead screw threadedly mounted on the support plate is rotatably connected to the roller head.

[0009] Preferably, the pressure-applying component further includes a slide rod slidably installed within the slider, with the end of the slide rod facing away from the slider fixed to the roller head.

[0010] Preferably, the top of the main carriage is closed, while the bottom is open.

[0011] Preferably, a secondary slide is separately installed at the bottom of the main slide, the top and bottom of the secondary slide are not enclosed, and a locking device is provided between the secondary slide and the main slide; when the main slide and the secondary slide are installed, the secondary slide is connected to the base.

[0012] Preferably, the locking component includes an insertion hole at the bottom of the main slide and an insertion block fixed at the top of the secondary slide. The insertion block is equipped with an elastic button, and the insertion hole has a limiting hole extending to the outside. When the insertion block is inserted into the insertion hole, the elastic button is located in the limiting hole.

[0013] Preferably, the top of the base has a mounting hole.

[0014] This utility model provides a rolling and leveling device for interior wall decoration, which has the following advantages compared with the prior art:

[0015] 1. The system is equipped with a carriage, electric push rod, and pressure application device. The pressure application device is used to adjust the contact between the roller and the wall. When the roller head is moved by the push-pull rod, the pressure applied by the roller head to the wall is constant due to the constraint of the carriage, resulting in a smooth wall surface.

[0016] 2. A locking mechanism is provided. After initially inserting the plug into the socket on the main carriage, press the elastic button inward until the plug is fully inserted into the socket. Then the elastic button will lock into the limiting hole, achieving a stable connection between the main carriage and the auxiliary carriage.

[0017] 3. A base and an electric push rod are provided. The base provides bottom support for the carriage, while the electric push rod holds the carriage between the top of the wall and the ground, thus ensuring stable movement of the roller head. Attached Figure Description

Detailed Implementation

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Example 1

[0027] Existing wall leveling devices, especially handheld roller-type devices, suffer from inconsistent pressure applied to the wall surface due to the worker's hand-held operation. This can result in varying degrees of flatness in different areas of the finished wall. Therefore, this embodiment provides a wall leveling roller device for interior wall decoration, such as... Figures 1-5As shown, it includes a main slide 1 and a roller head 8. The roller head 8 consists of a frame and a roller rotatably mounted on the frame. The top of the main slide 1 is closed, and the bottom is open. A base 5 is detachably mounted at the bottom of the main slide 1, and a mounting hole a is provided at the top of the base 5. An electric push rod 3 that can be tightly supported against the top wall is mounted at the top of the main slide 1. A soft pad 4 made of rubber is fixed to the movable end of the electric push rod 3. A slider 6 that moves vertically is slidably mounted inside the main slide 1. A push-pull rod 7 is rotatably mounted at one end of the slider 6, and a pressure-applying component 9 is mounted at the other end to adjust the contact degree between the roller head 8 and the side wall of the wall. Before the formal operation, the slider 6 is installed in the slide rail inside the main slide frame 1. Then, the bottom end of the main slide frame 1 is inserted into the mounting hole a of the base 5. After moving the device to a suitable position, the electric push rod 3 is activated, causing the soft pad 4 to move up and press tightly against the top of the wall, thereby achieving the support of the device. Then, the pressure application component 9 is adjusted to drive the roller head 8 close to the wall surface to be rolled until the roller contacts the wall surface. Then, the slider 6 is driven to move vertically through the push-pull rod 7, thereby driving the roller head 8 to move vertically, achieving the rolling of the wall surface. Due to the constraint of the main slide frame 1, the pressure applied by the roller head 8 to the wall surface is constant, and the final painted wall surface has good flatness.

[0028] The aforementioned pressure-applying component 9 includes a support plate 91 symmetrically fixed to the end of the slider 6. A lead screw 92, which is rotatably connected to the roller head 8, is threaded onto the support plate 91. Rotating the lead screw 92 moves the roller head 8 closer to and into contact with the wall, making adjustment convenient. The pressure-applying component 9 also includes a slide rod 93 slidably installed within the slider 6. The end of the slide rod 93 facing away from the slider 6 is fixed to the roller head 8. The slide rod 93 improves the stability of the roller head 8 during movement.

[0029] Example 2

[0030] Based on the embodiments, refer to Figures 3-5 A secondary slide 2 is separately installed at the bottom of the main slide 1. The top and bottom of the secondary slide 2 are not enclosed. The slide track structure on the secondary slide 2 is the same as that of the main slide 1, and both can cooperate with the movement of the slider 6. A locking fastener 10 is provided between the secondary slide 2 and the main slide 1. When the main slide 1 and the secondary slide 2 are installed, the secondary slide 2 is connected to the base 5. In actual operation, sometimes it is found that the distance between the ground and the wall is too large. In this case, it is difficult to make the soft pad 4 firmly support the top of the wall by relying solely on the main slide 1. In this case, the secondary slide 2 can be inserted into the mounting hole a of the base 5 first, the slider 6 can be installed in the slide track of the secondary slide 2, and then the bottom end of the main slide 1 can be inserted into the top end of the secondary slide 2. Then, the locking fastener 10 is used to fix it. After that, the electric push rod 3 is controlled to drive the soft pad 4 to firmly support the top of the wall. This can adapt to the scenario where the distance between the ground and the wall is large, better meet the actual use needs, and has good practicality.

[0031] To ensure the stability of the connection between the main slide 1 and the auxiliary slide 2, a locking fastener 10 is provided between them. The fastener includes an insertion hole 101 at the bottom of the main slide 1, which is a polygonal hole, and an insertion block 103 fixed at the top of the auxiliary slide 2. An elastic button 104 is installed on the insertion block 103. That is, a blind hole is opened on the side of the insertion block 103, and a spring is installed in the blind hole. A button that can pop out the blind hole is installed on the other end of the spring, which is called the spring button 104. A limiting hole 102 extending to the outside is opened on the insertion hole 101. When the insertion block 103 is inserted into the insertion hole 101, the elastic button 104 is located in the limiting hole 102. After inserting the insertion hole 101 on the main slide 1 into the insertion block 103, press the elastic button 104 inward until the insertion block 103 is fully inserted into the insertion hole 101. Then the elastic button 104 will be locked into the limiting hole 102, thus achieving a stable connection between the main slide 1 and the auxiliary slide 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
