Abstract
Description
Technical Field

[0002] Wall crack repair work is a common wall repair task in construction projects and daily maintenance.
[0003] When repairing wall cracks, the selection and use of repair tools directly affect the repair effect and work efficiency. At present, among the common wall crack repair tools on the market, the roller brush, as an important smearing tool, its design and use method have an important impact on the repair quality. However, most of the existing roller brushes for repair are of fixed design, that is, the relative position between the roller brush and the operating rod is fixed, and it cannot be flexibly adjusted according to the specific position and size of the wall crack. Although this fixed design has a simple structure, in actual use, for crack repair tasks at different heights and angles, the operator needs to frequently adjust their own posture or find a suitable angle, increasing the difficulty and labor intensity of the repair work. In addition, although some repair tools are designed with adjustable structures, the stability after adjustment is poor, and it is easy to shake or shift during the repair process, resulting in uneven application of the repair material and affecting the repair effect. This instability not only increases the risk of the repair work, but also may cause secondary damage to the wall. Therefore, a wall crack repair mechanism is proposed to solve the above-mentioned problems. Content of the Utility Model

[0026] Please refer to Figures 1-3 , a wall crack repair mechanism, including a main rod 1, an adjusting rod 2 and an adjusting and reinforcing component. A support seat 7 is bolted and fixed to the top end of the main rod 1. A rolling brush 8 is rotatably connected to the support seat 7. A threaded hole is provided at the bottom end of the main rod 1. The adjusting rod 2 is externally provided with threads and is threadedly connected to the threaded hole, providing an accurate lifting and adjusting mechanism and ensuring the accuracy during crack repair at different heights. A reinforcing component is provided outside the main rod 1;
[0027] The reinforcement component includes a support block 5 and an adjustment block 6. There are two support blocks 5, which are welded to the outside of one end of the main rod 1 close to the adjustment rod 2 on the opposite side. There are also two adjustment blocks 6, which are respectively located on both sides of the two support blocks 5. Guide rods 603 are inserted at the four corners of the adjustment block 6. One end of the guide rod 603 is welded to one side of the support block 5. The guide rod 603 ensures the linearity of the insertion block 602 during movement, avoiding jamming caused by deviation.
[0028] In this embodiment, the support seat 7 is composed of a T-shaped rod and an L-shaped column. The T-shaped rod is bolt-fixed to the top of the main rod 1. The middle of the rotary brush 8 is rotatably connected to the L-shaped column. The T-shaped rod design of the support seat 7 makes its connection with the main rod 1 more stable. Fixed by bolts, it is not only convenient to install, but also very convenient to disassemble and replace the rotary brush 8.
[0029] In this embodiment, two sets of first fixing holes 3 are arranged and distributed on the adjustment rod 2. The two sets of first fixing holes 3 are symmetrically distributed. After the height of the adjustment rod 2 is adjusted, it is fixed by inserting the insertion block 602 into the first fixing hole 3.
[0030] In this embodiment, a handheld part 4 is welded to the bottom end of the adjustment rod 2. A towel strip is arranged on the handheld part 4, providing a comfortable holding position for the user.
[0031] In this embodiment, the adjustment block 6 is composed of an arc-shaped block 601 and an insertion block 602. The arc-shaped block 601 covers the outside of the main rod 1 and can closely fit the main rod 1 to ensure the reinforcement effect. A spring 604 is arranged between the arc-shaped block 601 and the support block 5, so that the insertion block 602 can automatically reset when not affected by external force and is inserted into the first fixing hole 3 to achieve quick fixing and release of the fixing.
[0032] In this embodiment, a widened cake block is arranged at the other end of the guide rod 603 to prevent the arc-shaped block 601 from falling off and the spring 604 from being damaged due to excessive force when pulling the arc-shaped block 601.
[0033] In this embodiment, two sets of second fixing holes are symmetrically distributed on the outside of the main rod 1 corresponding to the insertion block 602. The insertion block 602 is inserted into the second fixing hole and the first fixing hole 3 in sequence.
[0034] Beneficial effects:
[0035] For the wall crack repair mechanism, after pulling the two adjusting blocks 6 to release the insertion connection between the insertion block 602 and the first fixing hole 3, by rotating the adjusting rod 2, due to the threaded connection between the threaded hole at the bottom end of the main rod 1 and the adjusting rod 2, flexible adjustment of the height can be achieved. After adjusting to the appropriate position, slightly rotate it until the first fixing hole 3 is aligned with the second fixing hole. Under the action of the spring 604, the insertion block 602 will be driven to re-insert into the first fixing hole 3, thus achieving the reinforcement effect. The guiding rod 603 is to ensure the correctness of the direction of movement of the insertion block 602 and prevent it from getting stuck due to deviation during movement.
