Description

Technical Field

[0001] This application relates to the field of grouting tools, and more particularly to a masonry grouting tool. Background Technology

[0002] During the construction of masonry structures in building engineering, it is often necessary to perform grouting on the wall surface (especially exposed brick walls). Grouting refers to filling the gaps between two adjacent masonry blocks with mortar, making the connection between adjacent masonry blocks stronger, preventing wind and rain from penetrating the interior of the wall, and making the wall surface clean, neat and beautiful.

[0003] Utility model patent CN217232825U discloses a grouting tool for masonry walls, including a holding support frame, a roller, and a grouting body. The roller is mounted on the holding support frame and can move along the masonry wall surface. The grouting body is mounted on the holding support frame and fits into the gap between adjacent masonry sections. The top of the grouting body protrudes from the roller so that it can extend into the gap.

[0004] One of the masonry wall grouting tools mentioned above connects the sleeve and the support shaft through a limiting component. The limiting component is a limiting screw, which requires rotating the limiting screw when rotating the sleeve, making operation inconvenient. Alternatively, if the limiting component is a pin, the pin may fall off and be lost when the tool is moved with the pin facing downwards, thus reducing its applicability. Utility Model Content

[0005] To address the aforementioned problems, this application provides a masonry grouting tool.

[0006] The masonry grouting tool provided in this application adopts the following technical solution:

[0007] A masonry grouting tool includes a handle and a rotating ring. The handle is provided with an adjustment assembly for limiting the rotation of the rotating ring. The adjustment assembly includes a U-shaped frame fixedly connected to one end of the handle, a fixed rod fixedly connected to the inner cavity of the U-shaped frame, the rotating ring being sleeved on the fixed rod, a baffle fixedly connected to one side of the fixed rod, and a push plate sleeved on the other side of the fixed rod. A plurality of annularly arranged insert rods are fixedly connected to the side wall of the push plate near the rotating ring. A plurality of insertion holes adapted to the insert rods are opened on one side wall of the rotating ring. A plurality of annularly arranged springs are fixedly connected between the push plate and the U-shaped frame. A grouting assembly is provided on the rotating ring.

[0008] By adopting the above technical solution, during use, pulling the push plate causes it to slide on the fixed rod, compressing the spring and pulling the insertion rod out of the insertion hole. Then, rotating the rotating ring adjusts the angle of the rotating ring. Releasing the push plate causes the spring to rebound, pushing the push plate towards the rotating ring, which then abuts against the baffle, allowing the insertion rod to be inserted into the insertion hole and fixing the rotating ring in place. This method avoids the problems of inconvenient operation when fixing the sleeve with a limit screw, and the easy fall-off of pin fixing, which reduces applicability.

[0009] Preferably, the grouting assembly includes multiple connecting rods fixedly connected to the side wall of the rotating ring, and each connecting rod has a grouting tooth fixedly connected to the end away from the rotating ring. Rollers are rotatably connected to the two side walls of the U-shaped frame.

[0010] By adopting the above technical solution, a person holds a rod and moves the roller along the wall, causing the connecting rod to insert the grouting teeth into the gap between adjacent masonry, thereby achieving grouting of the gap.

[0011] Preferably, the number of connecting rods is the same as the number of insert rods and they are distributed in a circular array.

[0012] By adopting the above technical solution, the rotating ring can be rotated at an angle, and when the plug is inserted into the plug hole, multiple connecting rods can be moved to the same position respectively, preventing the grouting teeth from failing to move to the appropriate position when adjusting different sizes of grouting teeth.

[0013] Preferably, each spring is provided with a movable tube, one end of which is fixedly connected to the U-shaped frame, and the other end of which is slidably provided with a movable rod, which is fixedly connected to the push plate.

[0014] By adopting the above technical solution, the stability of the spring can be improved by moving the tube and moving the rod, preventing the spring from bending when it contracts. At the same time, it can prevent the grouting teeth from being pushed by the rotating ring when grouting the wall, causing the rotating ring to rotate.

[0015] Preferably, the side wall of the fixed rod is provided with an annular limiting groove, and the inner wall of the rotating ring is fixedly connected with an annular limiting block, which is slidably disposed in the annular limiting groove.

[0016] By adopting the above technical solution, the rotating ring can be positioned using the annular limiting groove and the annular limiting block to prevent the rotating ring from moving on the fixed rod.

[0017] Preferably, a corrugated tube is fixedly connected between the push plate and the U-shaped frame, and all the springs are located inside the corrugated tube.

[0018] By adopting the above technical solution, the corrugated pipe can protect the spring and prevent mud and sand from entering the spring and causing damage.

[0019] Preferably, a rubber pad is fitted on the grip, the grip is hollow, and the rubber pad has multiple ventilation holes that communicate with the interior of the grip.

[0020] By adopting the above technical solution, the rubber pad improves the comfort of the person holding the bar, while the ventilation holes can improve air circulation and prevent the person from sweating and slipping due to prolonged holding.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the cooperative arrangement of structures such as a fixed rod, a baffle, and a push plate. In use, by pulling the push plate, the push plate slides on the fixed rod, compressing the spring and pulling the insertion rod out of the insertion hole. Then, by rotating the rotating ring, the angle of the rotating ring is adjusted. By releasing the push plate, the spring rebounds, pushing the push plate against the rotating ring, which abuts against the baffle, allowing the insertion rod to be inserted into the insertion hole and fixing the rotating ring. This avoids the problems of inconvenient operation when fixing with a limit screw while rotating the sleeve, and easy falling off when fixed with a pin, which reduces applicability.

[0023] 2. The stability of the spring can be improved by moving the tube and moving the rod, preventing the spring from bending when it contracts. At the same time, it can prevent the push plate from rotating, avoiding the rotating ring from rotating under the thrust when the grouting teeth are grouting the wall. The rotating ring can be positioned by the annular limiting groove and the annular limiting block to prevent the rotating ring from moving on the fixed rod. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a masonry grouting tool.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A masonry grouting tool includes a handle 1 and a rotating ring 2. The handle 1 is provided with an adjustment component for limiting the rotation of the rotating ring 2. The adjustment component includes a U-shaped frame 3, a fixing rod 4, a baffle 5, a push plate 6, an insertion rod 7, an insertion hole 8, and a spring 9.

[0032] The U-shaped frame 3 is fixedly connected to one end of the handle 1. The fixed rod 4 is set in the inner cavity of the U-shaped frame 3 and fixedly connected to the U-shaped frame 3 at both ends. The rotating ring 2 is sleeved on the fixed rod 4. The baffle 5 is fixedly connected to the fixed rod 4 and located on one side of the rotating ring 2. The push plate 6 is sleeved on the fixed rod 4 and located on the other side of the rotating ring 2. Multiple insertion rods 7 are provided and are all fixedly connected to the side wall of the push plate 6 near the rotating ring 2 and form a ring array. Multiple insertion holes 8 are provided and are all opened on one side wall of the rotating ring 2 and are adapted to the insertion rods 7. Multiple springs 9 are provided and are fixedly connected between the push plate 6 and the U-shaped frame 3 and form a ring array. The rotating ring 2 is provided with a grouting assembly.

[0033] Reference Figure 1 and Figure 2 The grouting assembly includes multiple connecting rods 10 fixedly connected to the side wall of the rotating ring 2. Each connecting rod 10 is fixedly connected to a grouting tooth 11 at the end away from the rotating ring 2. The grouting teeth 11 are of different sizes, which makes it convenient to replace the grouting teeth 11 of different sizes according to the gaps in the wall. Rollers 12 are rotatably connected to the side walls of the U-shaped frame 3. By holding the rod 1, the rollers 12 are moved along the wall surface, so that the connecting rod 10 inserts the grouting teeth 11 into the gaps between adjacent masonry, thereby grouting the gaps.

[0034] Reference Figure 1 and Figure 3The number of connecting rods 10 is the same as the number of insert rods 7 and they are arranged in a circular array. By rotating the rotating ring 2, the rotating ring 2 can be rotated at an angle, and then the insert rod 7 can be inserted into the insertion hole 8. This allows multiple connecting rods 10 to move to the same position, preventing the grouting teeth 11 from not being able to move to the appropriate position when adjusting different sizes of grouting teeth 11.

[0035] Reference Figure 2 Each spring 9 is equipped with a movable tube 13. One end of the movable tube 13 is fixedly connected to the U-shaped frame 3, and the other end of the movable tube 13 is slidably provided with a movable rod 14. The movable rod 14 is fixedly connected to the push plate 6. The movable tube 13 and the movable rod 14 can improve the stability of the spring 9 and prevent the spring 9 from bending when it contracts. At the same time, it can prevent the grouting teeth 11 from being pushed by the rotating ring 2 when grouting the wall, causing the rotating ring 2 to rotate.

[0036] Reference Figure 2 and Figure 3 The fixed rod 4 has an annular limiting groove 15 on its side wall, and an annular limiting block 16 is fixedly connected to the inner wall of the rotating ring 2. The annular limiting block 16 is slidably disposed in the annular limiting groove 15. The rotating ring 2 can be positioned by the annular limiting groove 15 and the annular limiting block 16 to prevent the rotating ring 2 from moving on the fixed rod 4.

[0037] Reference Figure 1 and Figure 2 A corrugated pipe 17 is fixedly connected between the push plate 6 and the U-shaped frame 3. The springs 9 are all located inside the corrugated pipe 17. The corrugated pipe 17 can protect the springs 9 and prevent mud and sand from entering the springs 9 and causing damage to the springs 9.

[0038] Reference Figure 1 and Figure 4 A rubber pad 18 is fitted on the grip 1. The grip 1 is hollow. The rubber pad 18 has multiple ventilation holes 19 that are connected to the inside of the grip 1. The rubber pad 18 improves the comfort of the person holding the grip 1. At the same time, the ventilation holes 19 can improve air circulation and prevent the person from holding it for a long time, causing their palms to sweat and making it easy to slip.

[0039] The implementation principle of a masonry grouting tool according to this application embodiment is as follows: In use, by pulling the push plate 6, the push plate 6 slides on the fixed rod 4, compressing the spring 9, and pulling the insertion rod 7 out of the insertion hole 8. Then, by rotating the rotating ring 2, the angle of the rotating ring 2 is adjusted according to the needs, and the appropriate grouting teeth 11 are moved out. Then, by releasing the push plate 6, the spring 9 rebounds, pushing the push plate 6 towards the rotating ring 2, and the rotating ring 2 abuts against the baffle 5, so that the insertion rod 7 is inserted into the insertion hole 8 and the rotating ring 2 is fixed. Then, the person holds the handle 1 and moves the roller 12 along the wall, so that the connecting rod 10 extends the grouting teeth 11 into the gap between adjacent masonry, so as to achieve grouting of the gap. This avoids the problems of fixed by the limit screw when rotating the sleeve, which is inconvenient to operate, and fixed by the pin shaft, which is easy to fall off, thus reducing the applicability.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
