[0028] 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.

[0029] Example 1:

[0030] like Figures 1 to 5 As shown, this embodiment provides a building paint roller for preventing falling materials, comprising: a telescopic mechanism including a telescopic rod 11, a telescopic rod 25 slidably disposed inside the telescopic rod 11, and a rotation adjustment component on one side of the telescopic rod 11 for telescopically fixing the telescopic rod 25; a paint mechanism including a device bracket 21 disposed on the end of the telescopic rod 25 away from the telescopic rod 11, a connecting column 22 rotatably disposed on the inner wall of the middle of the device bracket 21, a connecting column 22 fixedly disposed in the middle of the device bracket 21, and the connecting column 22 rotatably connected through the connecting column 22, a paint roller 31 rotatably disposed on the connecting column 22, rolling bearings 23 disposed on both sides of the paint roller 31, and a protective component on one side of the paint roller 31 for catching falling materials.

[0031] In this embodiment, the telescopic mechanism and the painting mechanism constitute the building painting roller device for preventing falling materials involved in this application, realizing a building painting roller for preventing falling materials. The painting roller in this application can be used as long as it needs to be painted with the help of falling materials. This application does not limit the specific type of painting roller.

[0032] In this embodiment, the rotating block 13 is turned, and its threaded connection with the threaded post 12 is used to move the rotating block 13 on the threaded post 12, thereby applying pressure to the locking block 14.

[0033] In this embodiment, when it is necessary to adjust the operating length of the paint roller, the second telescopic rod 15 can be slid into the first telescopic rod 11 to a suitable position, and then fixed by rotating the adjustment assembly.

[0034] It should be noted that the second telescopic rod 15 is also a hollow cylinder, made of the same or similar material as the first telescopic rod 11, and can slide smoothly inside the first telescopic rod 11, enabling the length adjustment function of the entire telescopic mechanism.

[0035] Specifically, the rotation adjustment assembly includes: a threaded post 12, arranged on one side of the telescopic rod 11; a locking block 14, fixedly arranged on one side of the telescopic rod 11; and a rotating block 13, threadedly connected to the threaded post 12, with the locking block 14 arranged inside the rotating block 13.

[0036] In this embodiment, after the locking block 14 is squeezed, the gap between its fixing blocks becomes smaller, and the fixing blocks are in close contact with the telescopic rod 15, fixing the telescopic rod 15 in the current position by friction.

[0037] Specifically, multiple sets of fixing blocks are fixed on the side of the locking block 14 away from the telescopic rod 11, and there is a gap between each set of fixing blocks. When the rotating block 13 is turned, the locking block 14 is squeezed, thereby causing the locking block 14 to abut against the telescopic rod 15, which is used to limit the position of the locking block 14 and the telescopic rod 15.

[0038] In a preferred embodiment, the fixing block is in close contact with the outer surface of the telescopic rod 15, generating sufficient friction to restrict the movement of the telescopic rod 15.

[0039] Specifically, the protective components include: a connecting rod 24, which is fixedly arranged on one side of the connecting column 22; a positioning pin 26, which passes through the device bracket 21 and is connected to the connecting rod 24 for fixing the connecting rod 24; and a receiving box 25, which is fixedly arranged on the connecting rod 24.

[0040] It should be noted that when the position of the receiving box 25 needs to be adjusted, the positioning pin 26 is pulled out, and the connecting rod 24 can rotate around the connecting column 22, thereby adjusting the receiving box 25 to the appropriate position. Then the positioning pin 26 is inserted to fix it.

[0041] Specifically, there are two sets of connecting rods 24, both of which are fixedly arranged on one side of the two sets of connecting posts 22.

[0042] In a preferred embodiment, the connecting rod 24 serves as a bridge connecting the receiving box 25 and the connecting column 22, and maintains the stable position of the receiving box 25 under the fixing action of the positioning pin 26.

[0043] Specifically, the receiving box 25 is a concave groove, and when the positioning pin 26 is pulled out, the connecting rod 24 drives the receiving box 25 to rotate on one side of the brush roller 31, which is used to adjust the position of the receiving box 25 and the brush roller 31 and catch the material falling from the brush roller 31.

[0044] It should be noted that when the position of the receiving box 25 needs to be adjusted, the positioning pin 26 is pulled out and inserted to achieve the rotation and fixation of the receiving box 25, ensuring that the receiving box 25 can effectively catch the falling material.

[0045] Specifically, the surface of the rotating block 13 is provided with multiple sets of edges and corners for rotating the rotating block 13.

[0046] In this embodiment, by using a tool or by directly holding the corner of the rotating block 13, a rotational force is applied, causing the rotating block 13 to rotate on the threaded post 12, thereby achieving the squeezing of the locking block 14 and the fixing or loosening of the telescopic rod 15.

[0047] Example 2:

[0048] Based on Embodiment 1, in order to facilitate manual rotation of the rotating block 13, multiple sets of sharp edges are provided on the outer surface of the rotating block 13;

[0049] In use, the operator can twist the rotating block 13 downwards to expose the locking block 14, pull out the telescopic rod 15 to extend or retract it, and tighten it upwards to lock it. When painting is needed, the positioning pin 26 is pulled out, and the receiving box 25 follows the position to be painted by the operator under gravity. The receiving box 25 is always below the painting roller 31 to catch the material that leaks out of the painting roller 31. The painting roller 31 has a rolling bearing 23, which can reduce resistance and make rolling easier during painting. When not in use, the positioning pin 26 can be inserted into the limiting groove in the connecting rod 24 to fix it.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
