Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building decoration technology, and in particular to a grout sealing device for decoration. Background Technology
[0002] During interior decoration, grout sealing devices are needed to beautify the gaps between adjacent tiles. Grout is applied into the gaps between adjacent tiles using a grout gun, and then smoothed out with a scraper. This step-by-step process reduces construction efficiency. Existing grout sealing devices are not convenient for applying and smoothing grout between adjacent tiles, thus reducing the efficiency of grout sealing between adjacent tiles.
[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN219528302U) for a decorative grout extrusion device. This device includes a vehicle body assembly, a grout extrusion assembly, and a power conversion assembly. The grout extrusion assembly comprises a material bottle, a piston rod, a lifting block, and a screw. The material bottle is mounted on the vehicle body assembly, and the piston rod slides within the bottle's cavity, forming a piston mechanism to extrude the grout. The lifting block is connected to the piston rod and engages with the vehicle body assembly in a circumferential limiting and vertical sliding configuration. The screw is vertically rotatably mounted on the vehicle body assembly and screwed to the lifting block. The power conversion assembly converts the power of the vehicle body assembly into the power to drive the screw. This invention converts the power of the vehicle body assembly's movement into the power of the grout extrusion assembly to extrude the grout. Users only need to push the vehicle body assembly forward without additional grout extrusion, making it more convenient and flexible. However, this device does not consider smoothing the grout after it has been introduced into the gaps between adjacent tiles, reducing the device's efficiency in grouting adjacent tiles. Utility Model Content
[0004] The purpose of this utility model is to provide a decorative grout sealing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tile grouting device, comprising a tile grouting gun and a scraper assembly for smoothing the grout. The scraper assembly includes two fixed bearings and a connecting ring. The inner rings of the two fixed bearings are interference-fitted with the sides of the tile grouting gun. The inner ring surface of the connecting ring is connected to the fixed bearings. A connecting plate is connected to the side of the connecting ring. A slide is provided on the adjacent sides of the two connecting plates. A sliding plate is slidably connected to the inner side wall of the slide. The two end faces of the sliding plate are connected to the two connecting plates. An L-shaped scraper for smoothing the grout is connected to the side of the slide. A fixing bolt is threadedly connected to the outer side wall of the slide. The threaded end face of the fixing bolt abuts against the sliding plate. A limiting plate is connected to the side of the upper connecting ring away from the connecting plate. A limiting bolt is threadedly connected to the bottom surface of the limiting plate.
[0006] Preferably, the top of the caulking gun is provided with a support component, which includes a C-shaped support frame and an inverted U-shaped fixing frame.
[0007] Preferably, a rotating roller is rotatably connected to the inner side wall of the fixed frame, and the top surface of the fixed frame is connected to the support frame.
[0008] Preferably, the inner top wall and inner bottom wall of the support frame are both embedded with fixed limit bearings, and the inner ring of the limit bearing is interference-fitted with a rotating block.
[0009] Preferably, the two rotating blocks are connected to threaded rods on adjacent sides, and the threaded rods are threadedly connected to threaded plates.
[0010] Preferably, the side of the threaded plate is slidably connected to the inner wall of the support frame, and the bottom surface of the threaded plate is connected and fixed to the grout gun.
[0011] Preferably, the top surface of the threaded portion of the limiting bolt abuts against the threaded plate, and the top surface of the upper rotating block is connected to a rotating plate.
[0012] Preferably, the top surface of the rotating plate is threaded with an abutment bolt, and the threaded end face of the abutment bolt abuts against the support frame.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This decorative tile grouting device uses a grout gun to apply grout to the gaps between adjacent tiles, achieving tile grout sealing. Since the grout needs to be smoothed after application, applying it in stages reduces efficiency. This device improves efficiency by directly smoothing the grout after application, using a scraper assembly. The device releases the limiting bolt from the threaded plate, and with two fixed bearings and a connecting ring, the scraper plate's position is adjusted. Simultaneously, the slide moves along the path of the sliding plate. Adjusting the vertical position of the scraper plate during transmission ensures thorough smoothing of the grout, further enhancing the device's tile grouting efficiency.
[0015] This decorative grout sealing device features a support assembly that provides support and fixation for the grout gun. The rotating plate rotates around a rotating block as its axis, causing the threaded rod to rotate during transmission. This allows the threaded plate to move along the threaded path of the rod, adjusting the vertical position of the grout gun to a designated height for grout sealing, thus improving the quality of the grout sealing. A fixing frame secures the rotating roller, allowing it to roll on the ground, eliminating the need to manually operate the grout gun and reducing user fatigue. A connecting bolt moves along the threaded path of the rotating plate, bringing its threaded end face into contact with the support frame, thereby fixing the position of the rotating plate and preventing the grout gun from wobbling or shifting during transmission.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0027] To address the issue of reduced efficiency in tile grouting when using decorative grout sealing devices without considering the direct application of grout, please refer to [link to relevant documentation]. Figures 1 to 5 The structure of the device body includes a tile grout gun 1 for tile decoration and grouting, and a scraper assembly 2 for smoothing the grout. The scraper assembly 2 includes two fixed bearings 3 and a connecting ring 4. The inner rings of the two fixed bearings 3 are interference-fitted with the side of the tile grout gun 1. The inner ring surface of the connecting ring 4 is connected to the fixed bearings 3. A connecting plate 5 is connected to the side of the connecting ring 4. A slide 7 is provided on the adjacent side of the two connecting plates 5. A slide plate 6 is slidably connected to the inner side wall of the slide 7. The two end faces of the slide plate 6 are connected to the two connecting plates 5. An L-shaped scraper 8 for smoothing the grout is connected to the side of the slide 7. A fixing bolt 9 is threadedly connected to the outer side wall of the slide 7. The threaded end face of the fixing bolt 9 abuts against the slide plate 6. A limiting plate 10 is connected to the side of the upper connecting ring 4 away from the connecting plate 5. A limiting bolt 11 is threadedly connected to the bottom surface of the limiting plate 10.
[0028] In this embodiment, grout is introduced into the gaps between adjacent tiles using a grout gun 1, thus achieving grout sealing. After introducing the grout into the gaps between adjacent tiles, it needs to be smoothed out. However, continuously introducing and smoothing the grout reduces the efficiency of the device. The scraper assembly 2 smooths out the grout introduced into the gaps between adjacent tiles, improving the efficiency of the device. The two fixed bearings 3 and connecting ring 4 allow for easy adjustment of the relative position of the scraper plate 8 and the grout gun 1 during transmission, adapting to the usage environment requirements of the device. The limiting bolt 11 moves along the threaded path of the limiting plate 10. When the top surface of the threaded part of the limiting bolt 11 is in close contact with the bottom surface of the threaded plate 17, the position of the scraper assembly 2 is fixed under the action of frictional resistance, improving the structural stability of the device components. The two connecting plates 5 provide support and fixation for the slide plate 6, allowing the slide 7 to move vertically along the path of the slide plate 6. During the transmission process, the vertical height of the scraper plate 8 is adjusted to the specified height for use, allowing the grouting device to directly scrape the grout after introducing it into the gap between adjacent tiles, improving the efficiency of the device in grouting tiles. The fixing bolt 9 moves along the threaded path of the slide 7, and the end face of the threaded part of the fixing bolt 9 is in close contact with the slide plate 6, fixing the position of the slide 7 under the action of frictional resistance.
[0029] Specifically, the top of the grout gun 1 is provided with a support component 12, which includes a C-shaped support frame 13 and an inverted U-shaped fixing frame 20. The inner side wall of the fixing frame 20 is rotatably connected to a rotating roller 21, and the top surface of the fixing frame 20 is connected to the support frame 13.
[0030] In this embodiment, the rotation position of the rotating roller 21 is fixed by the fixing frame 20, so that the rotating roller 21 rolls on the ground. There is no need to hold the grouting device to grout the tiles, which reduces the fatigue of the user and improves the ease of use of the device. However, the user needs to adjust the direction of the grouting device on the tiles in real time.
[0031] Specifically, the inner top and bottom walls of the support frame 13 are both embedded with fixed limit bearings 14. The inner ring of the limit bearing 14 is interference-fitted with a rotating block 15. The two rotating blocks 15 are connected to adjacent sides with threaded rods 16. The threaded rods 16 are threadedly connected to threaded plates 17. The side of the threaded plate 17 is slidably connected to the inner side wall of the support frame 13. The bottom surface of the threaded plate 17 is connected and fixed to the grout gun 1.
[0032] In this embodiment, when the threaded rod 16 rotates, the threaded plate 17 moves along the threaded path of the threaded rod 16. During the transmission process, the vertical position of the grout gun 1 is adjusted so that the grout gun 1 is moved to the specified height for use. The limit bearing 14 is set to fix the rotation position of the rotating block 15. Under the connection provided by the two rotating blocks 15, the rotation position of the threaded rod 16 is fixed, thereby improving the structural stability of the device components.
[0033] Specifically, the top surface of the threaded portion of the limiting bolt 11 abuts against the threaded plate 17, the top surface of the upper rotating block 15 is connected to the rotating plate 18, the top surface of the rotating plate 18 is threadedly connected to the abutting bolt 19, and the end face of the threaded portion of the abutting bolt 19 abuts against the support frame 13.
[0034] In this embodiment, the rotating plate 18 is pushed, causing the threaded rod 16 to rotate during the circumferential movement of the rotating plate 18, which in turn causes the abutment bolt 19 to rotate. The abutment bolt 19 moves along the threaded path of the rotating plate 18, and the threaded end face of the abutment bolt 19 is in close contact with the top surface of the support frame 13. Under the action of frictional resistance, the position of the rotating plate 18 is fixed, and the grout gun 1 is prevented from shaking or shifting during the transmission process.
[0035] The grout gun 1 is existing technology. Its working principle, size and model are not related to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0036] Working principle
[0037] When using this decorative grout sealing device, the user pushes the rotating plate 18 to rotate the threaded rod 16. With the connection of two limit bearings 14 and the rotating block 15, the threaded plate 17 moves smoothly vertically along the threaded path of the threaded rod 16, allowing the grout gun 1 to be adjusted to the specified height to perform grout sealing on the tiles. The position of the rotating plate 18 is fixed by the abutment bolt 19, so that the rotating roller 21 is located on the surface of the tile. During the rolling process, the grout gun 1 sprays grout sealant to perform grout sealing on the tile.
[0038] Adjust the position of the scraper 8 according to the moving direction of the grout sealing device. The scraper 8 is located behind the grout sealing gun 1 in the direction of travel, so that the limiting bolt 11 moves along the threaded path of the limiting plate 10. The top surface of the threaded part of the limiting bolt 11 is in close contact with the threaded plate 17. Fix the position of the scraper 8 during the transmission process, so that the slide 7 moves along the path of the slide plate 6. Adjust the vertical position of the scraper 8 so that the scraper 8 can scrape the grout sealant. Fix the position of the slide 7 by fixing bolt 9.
