[0002] Currently, in order to prevent the exterior walls of buildings from being eroded by wind, rain, snow, etc., and to serve a decorative purpose, the exterior walls of buildings need to be painted. Generally, a roller brush is used when painting the exterior walls of buildings. Workers need to move the roller brush along the surface of the exterior wall, and the roller brush will drive the paint to be applied evenly to the surface of the exterior wall.
[0003] In the existing technology, the handle length of the roller brush is fixed, which makes it inconvenient for workers to operate when painting; and during the painting process, the paint dipped on the surface of the roller brush is easy to drip downwards, and the dripping paint will continue to splash onto the ground or workers' clothes, which is difficult to clean. Based on the above problems, we propose a roller brush for construction engineering. Utility Model Content
[0004] The purpose of this utility model is to provide a roller brush for construction engineering in order to solve the problems mentioned above.

A storage groove is formed on the side wall of the long groove on one side of the limiting magnetic sheet. The limiting magnetic sheet is slidably connected inside the storage groove. A magnetic block that attracts the limiting magnetic sheet is embedded in the other side wall of the long groove. By the relative sliding of the handle inside the sleeve and the engagement and fixation of the locking blocks and handle by the limiting magnetic sheet, the overall height of the handle and the sleeve can be freely adjusted to facilitate painting operations.
[0007] As a further improvement of this utility model: the connecting frame has a U-shaped frame structure, and the spacing between the inner side walls of the U-shaped frame matches the length of the outer wall of the receiving box.
[0008] As a further improvement of this utility model, a small gap is left between the bottom outer wall of the receiving box and the bottom inner wall of the connecting frame.
[0009] As a further improvement of this utility model, the thickness and curvature of the card block are matched with the thickness and curvature of the side wall of the sleeve.
[0010] As a further improvement of this utility model, the spacing between two adjacent card blocks is matched with the height of the limiting magnetic sheet.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 In this embodiment of the utility model, a roller brush for construction engineering includes a roller brush 1. A connecting frame 2 is rotatably connected to both sides of the roller brush 1. A receiving box 3 is provided on the inner side of the connecting frame 2. Symmetrically distributed protrusions 4 are formed on the outer walls of both sides of the receiving box 3. Symmetrically distributed circular grooves 5 are formed on the inner walls of both sides of the connecting frame 2. The protrusions 4 are rotatably connected to the interior of the corresponding circular grooves 5. The receiving box 3 receives the paint dripping from the surface of the roller brush 1 to prevent the paint from splashing onto the ground or workers' clothes and causing a difficult-to-clean situation.
[0022] A handle 6 is fixedly connected to the bottom of the connecting frame 2. A sleeve 7 is slidably connected to the outside of the handle 6. A vertical long groove 8 is opened on the end wall of the sleeve 7. A row of evenly distributed locking blocks 9 is fixedly connected to the end wall of the handle 6 inside the long groove 8. A limiting magnetic sheet 10 is engaged between the two uppermost locking blocks 9. A handle 11 for easy movement by the user is fixedly connected to the end wall of the limiting magnetic sheet 10. A storage groove 12 is opened on the side wall of the long groove 8 on one side of the limiting magnetic sheet 10. The limiting magnetic sheet 10 is slidably connected inside the storage groove 12. A magnetic block 13 that attracts the limiting magnetic sheet 10 is embedded in the other side wall of the long groove 8. By the relative sliding of the handle 6 inside the sleeve 7 and the engagement and fixation of the locking blocks 9 and the handle 6 by the limiting magnetic sheet 10, the overall height of the handle 6 and the sleeve 7 can be freely adjusted to facilitate the painting operation by the worker.
[0023] In this embodiment: by adding a receiving box 3 below the roller brush 1, and the receiving box 3 can be rotatably connected to the connecting frame 2 through the protrusions 4 and the round grooves 5 on both sides, the receiving box 3 can flexibly receive the paint dripping from the surface of the roller brush 1, so as to effectively prevent the dripping paint from splashing onto the ground or workers' clothes and causing a difficult-to-clean situation.
[0024] When the length needs to be adjusted, the user can pinch the handle 11 to move the limiting magnetic piece 10 into the storage slot 12. When the limiting magnetic piece 10 is completely dislodged from the long slot 8, the user can use the other hand to move the sleeve 7 up and down. The sleeve 7 can then slide relative to the handle 6 through the sliding of the long slot 8 and the locking block 9 to change the overall length. When the overall length of the sleeve 7 and the handle 6 is appropriate, the user can directly release the handle 11. Under the attraction of the limiting magnetic piece 10 and the magnetic block 13, the limiting magnetic piece 10 will automatically move towards the magnetic block 13. In this way, the limiting magnetic piece 10 will re-lock between the two locking blocks 9 to fix the overall length of the sleeve 7 and the handle 6 for normal painting use.
[0025] Please refer to this carefully. Figures 1-4 The connecting frame 2 has a U-shaped frame structure, and the spacing between the inner side walls of the U-shaped frame matches the length of the outer wall of the receiving box 3.
[0026] In this embodiment, the U-shaped frame structure of the connecting frame 2 can be well connected to the roller brush 1 in rotation, and can also be firmly connected to the receiving box 3 through the protrusions 4 and the circular grooves 5.
[0027] Please refer to this carefully. Figures 1-4 There is a small gap between the bottom outer wall of the receiving box 3 and the bottom inner wall of the connecting frame 2.
[0028] In this embodiment, the gap between the receiving box 3 and the connecting frame 2 is to allow the receiving box 3 to rotate slightly so that the received paint can be poured out and the inside of the box can be cleaned. The small gap is to prevent the receiving box 3 from rotating too much and causing the paint inside to spill out.
[0029] Please refer to this carefully. Figure 1 , 3 The thickness and curvature of the card block 9 match the thickness and curvature of the side wall of the sleeve 7.
[0030] In this embodiment, the structural dimensions of the locking block 9 and the sleeve 7 are compared so that their outer walls can have a smooth arc, so as to prevent the locking block 9 from protruding from the sleeve 7 and causing inconvenience to the user in gripping the sleeve 7.
[0031] Please refer to this carefully. Figure 1 , 3 ~4, the spacing between two adjacent card blocks 9 matches the height of the limiting magnetic sheet 10.
[0032] In this embodiment, the comparison between the spacing of the locking blocks 9 and the height of the limiting magnetic sheet 10 is to ensure the stability of the limiting magnetic sheet 10 before it is engaged with the locking blocks 9, thereby ensuring that the overall length of the grip 6 and the sleeve 7 is adjusted and fixed securely.
[0033] Please refer to this carefully. Figures 4-5The storage slot 12 is composed of a square slot and two horizontal slots at one end of the square slot. The size and curvature of the square slot correspond to the size and curvature of the limiting magnetic sheet 10. The position and height of the two horizontal slots correspond to the position and diameter of the horizontal bar of the handle 11.
[0034] In this embodiment, the special structure of the storage groove 12 and the size of each part compared with the limiting magnetic sheet 10 and the handle 11 are all to ensure that the storage groove 12 can allow the limiting magnetic sheet 10 and the handle 11 to completely disengage from the long groove 8, so that the locking block 9 can slide smoothly along the long groove 8 to change the overall length of the handle 6 and the sleeve 7.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
