Description

Technical Field

[0001] The utility model relates to a glue injection device, in particular to a glue injection device for building wall cracks, belonging to the technical field of wall repair. Background Art

[0002] Wall cracks are cracking phenomena that occur in the wall part of a building structure. According to the different materials of the materials themselves, they can be divided into concrete wall cracks, brick masonry wall cracks, new partition board cracks, and cracks generated by walls of different materials.

[0003] A wall crack repair device disclosed in the Chinese Patent Application Publication Specification CN221373030U. When repairing wall cracks, the nozzle injects repair glue into the cracks while moving. At the same time, by controlling the rotation of the control plate, while the nozzle repairs the wall cracks, the moving work box drives two cleaning brushes that continuously move up and down to clean the surface of the repaired cracks, and the subsequent cleaning work is completed simultaneously during the wall crack repair work, greatly improving the repair efficiency and work efficiency of wall cracks.

[0004] Although the above patent solution can clean the surface of the repaired cracks through two cleaning brushes, the distance between the two cleaning brushes cannot be cleaned. Only when the position of the moving glue injection is reached can the cleaning plate clean it. Before the device moves to the uncleaned area, part of the overflowing repair glue may partially solidify. The solidified glue has a certain hardness, and when the cleaning plate cleans the solidified glue, collisions may occur, resulting in damage to the cleaning plate. Moreover, the glue of this device is not flattened and fully pressed into the cracks, which may lead to insufficient contact between the glue and the crack edge, reducing the repair effect and the adhesion of the glue. Content of the Utility Model

[0005] The utility model provides a glue injection device for building wall cracks, which can buffer the collision received by the cleaning plate and can also fully press the glue into the cracks at the same time, improving its repair effect and the adhesion of the glue.

A flattening mechanism is provided on the fixing plate, and a cleaning mechanism is provided on the flattening mechanism.

[0007] The flattening mechanism includes two first driving rods hinged to one side of the fixed plate. Fixed blocks are hinged to the ends of the two first driving rods away from the fixed plate. Second driving rods are hinged to the sides of the two fixed blocks away from the first driving rods. A fixed shell is hinged to the end of the second driving rod away from the fixed block. An elastic cord is fixed to the sides of the two fixed blocks close to each other. A rotating rod is fixed to the inner wall of the fixed shell, and a flattening roller is rotatably connected to the outer surface of the rotating rod.

[0008] The cleaning mechanism includes a fixed cylinder hinged to the bottom surface of the fixed shell. A sliding plate is slidably connected to the inner wall of the fixed cylinder. A pressing rod is fixed to the side of the sliding plate away from the fixed shell, and one end of the pressing rod penetrates through the fixed cylinder and extends to the outside. A cleaning plate is fixed to the end of the pressing rod outside the fixed cylinder, and the top end of the cleaning plate is hinged to the bottom surface of the fixed shell. A plurality of rubber balls are arranged inside the fixed cylinder.

[0009] Further, a scraping plate is fixed to the side of the fixed shell close to the flattening roller, and one side of the scraping plate is in contact with the outer surface of the flattening roller.

[0010] Further, a storage bin is fixed to the upper surface of the base, and a feed inlet is fixedly communicated with the upper surface of the storage bin.

[0011] Further, a pump is fixed to the upper surface of the base. The input end of the pump is fixedly communicated with a feed pipe, and the end of the feed pipe away from the pump is fixedly communicated with the storage bin.

[0028] A scraping plate 208 is fixed on the side of the fixed shell 205 close to the flattening roller 207, and one side of the scraping plate 208 is in contact with the outer surface of the flattening roller 207.

[0029] Through the arranged flattening roller 207, the wall surface after injecting glue can be flattened. Through the cooperative arrangement of the first driving rod 201, the fixed block 202, the second driving rod 203 and the elastic rope 204, the flattening roller 207 can be closely attached to the wall surface, so that the glue can be fully pressed into the cracks, improving its repair effect and the adhesion of the glue.

[0030] Please refer specifically to Figure 3 and Figure 4 , the cleaning mechanism 3 includes a fixed cylinder 302 hinged to the bottom surface of the fixed shell 205. A sliding plate 303 is slidably connected to the inner wall of the fixed cylinder 302. A pressing rod 304 is fixed on the side of the sliding plate 303 away from the fixed shell 205.

The top end of the cleaning plate 301 is hinged to the bottom surface of the fixed shell 205. A plurality of rubber balls 305 are arranged inside the fixed cylinder 302.

[0031] The wall surface after injecting glue can be cleaned through the cleaning plate 301. When the cleaning plate 301 collides with the cured glue, the cleaning plate 301 will push the pressing rod 304 to move, and the pressing rod 304 will squeeze the rubber balls 305 through the sliding plate 303. The elasticity of the rubber balls 305 can buffer the collision received by the cleaning plate 301.

[0034] Working principle: When in use, move the device in front of the crack that needs to be injected with glue, then aim the nozzle 10 at the crack by holding the handle 13, and at the same time make the flattening roller 207 contact the wall surface. Then push the fixing plate 4 to press the nozzle 10 into the crack. At this time, the fixing plate 4 will drive the first driving rod 201 to move, the first driving rod 201 will drive the fixing block 202 to move, and the fixing block 202 will drive the second driving rod 203 to move. The second driving rod 203 can make the flattening roller 207 closely fit on the wall surface through the fixed shell 205, so that the glue can be fully pressed into the crack, improving its repair effect and the adhesion of the glue. At the same time, the movement of the fixing block 202 will stretch the elastic cord 204 to generate a pulling force, and the pulling force can be used to restore the flattening roller 207 to its original position when not in use. Then start the pump 7 to pump the glue in the storage tank 5 to the nozzle 10 through the discharge hose 9, so as to inject glue into the crack. After that, move the nozzle 10, and the cleaning plate 301 can clean the wall surface after injecting glue. When the cleaning plate 301 collides with the cured glue, the cleaning plate 301 will push the pressure rod 304 to move, and the pressure rod 304 will squeeze the rubber ball 305 through the sliding plate 303. The elasticity of the rubber ball 305 can buffer the collision received by the cleaning plate 301.
