Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and specifically relates to a putty powder applying device for construction. Background Technique

[0002] Putty powder is a base material used for wall repair and leveling, laying a good foundation for the next decoration (painting or wallpapering); putty powder is divided into two types: interior wall and exterior wall. Exterior wall putty powder has high colloidal property and strength to resist wind and sun exposure, and its environmental protection index is slightly lower. Interior wall putty powder has better comprehensive index and is healthy and environmentally friendly, so it is not used for exterior walls, and exterior wall putty powder is not used for interior walls.

[0003] The patent application number CN202121186524.6 discloses a putty powder applying device for construction. This solution can simultaneously paint both sides of the corner of the crossbeam by setting a horizontal roller and a vertical roller at the end of the bracket, thereby improving efficiency. However, this solution has certain defects and deficiencies. First, the two rollers are vertically arranged, making the device only applicable to the painting of the corner of the crossbeam. The angle between the two rollers cannot be adjusted, so it cannot be set horizontally, resulting in low efficiency when facing horizontal wall painting. At the same time, due to the inability to adjust the angle between the rollers, it cannot meet the painting treatment of different corners, having certain defects and deficiencies, so improvement is needed.

[0027] Embodiment

[0028] As shown in Figure 1 , Figure 2 and Figure 3 , a putty powder coating device for building construction proposed in an embodiment of the present utility model includes: two L-shaped protective frames 1, which are rotatably connected through a rotating shaft 11; two roller assemblies 2, both of which are installed on the corresponding L-shaped protective frames 1. The roller assembly 2 includes a threaded rod 201 and a roller body 203. The threaded rod 201 is threadedly connected to the corresponding L-shaped protective frame 1, and one end of the threaded rod 201 is fixedly connected with a circular protrusion 205. And one side of the roller body 203 is rotatably connected with a sleeve 204, and the sleeve 204 is fixed on the circular protrusion 205 through a screw 202; a bracket 5, the lower end of the bracket 5 is fixedly connected with a fixed seat 10, and a rotating frame 12 is arranged at the end of the rotating shaft 11. The fixed seat 10 and the rotating frame 12 are fixedly connected, and a protective cylinder 7 is threadedly connected to the bracket 5. A connecting seat 6 is rotatably connected to the protective cylinder 7, and support arms 4 are rotatably connected between both sides of the connecting seat 6 and the corresponding L-shaped protective frames 1

[0029] It should be noted that the L-shaped protective frame 1 is of an L-shaped structure. Two L-shaped protective frames 1 are arranged in cooperation and can be rotationally adjusted. By installing the roller assembly 2 on the L-shaped protective frame 1, the angle of the roller assembly 2 can be adjusted after the L-shaped protective frame 1 rotates. The roller assembly 2 is composed of components such as a threaded rod 201, a roller body 203, and a sleeve 204. The sleeve 204 is fixed on the circular protrusion 205 through a screw 202 to realize the installation of the roller body 203. The roller body 203 is used for the painting of putty powder and can rotate on the sleeve 204 during the painting process, and then normal painting operations can be carried out. By threadedly connecting the threaded rod 201 to the corresponding L-shaped protective frame 1, the telescopic distance of the roller body 203 can be adjusted after the threaded rod 201 rotates. When the L-shaped protective frame 1 rotates, the position of the roller body 203 can be adjusted to avoid frictional collision between the two roller bodies 203 during rotation. After closing, the position of the roller body 203 is adjusted through the threaded rod 201 to align the two roller bodies 203, and then planar painting can be carried out. It should also be noted that in actual use, the roller bodies 203 in the two roller assemblies 2 can be staggered with each other to avoid incomplete painting when painting the corners of the crossbeam after rotation, and it can be designed and used according to actual situations. At the same time, the comparison scheme mentioned in the background technology can be referred to. This scheme adjusts the position of another roller through a lead screw, and then seamless painting at the corners can be carried out. This method is a known prior art and will not be elaborated (not shown in the figure). By arranging a rotating frame 12 on the rotating shaft 11, the two L-shaped protective frames 1 can be angularly adjusted around the rotating shaft 11 on the rotating frame 12. The fixed seat 10 at the lower end of the bracket 5 is connected and fixed to the rotating frame 12, and then the two L-shaped protective frames 1 can stably rotate around the rotating frame 12. By threadedly connecting a protective cylinder 7 to the bracket 5, the height of the protective cylinder 7 can be adjusted. The connecting seat 6 is rotatably connected to the protective cylinder 7. When the position of the protective cylinder 7 changes, the two L-shaped protective frames 1 can be pulled through the support arm 4, so that the L-shaped protective frame 1 rotates around the rotating shaft 11, and then the angle of the roller body 203 can be adjusted.

[0030] As Figure 1 shown, in some embodiments, the support arm 4 is rotatably connected to the L-shaped protective frame 1 and the connecting seat 6 through the rotating seats 3 provided at both ends thereof, so that the support arm 4 rotates stably.

[0031] As Figure 1 shown, in some embodiments, an external thread 8 is provided on the outer wall of the bracket 5, and an internal thread adapted to the external thread 8 is provided on the inner wall of the protective cylinder 7 to realize the threaded connection of the protective cylinder 7 to the bracket 5.

[0032] As Figure 1 shown, in some embodiments, a control handle 9 is fixedly connected to the upper part of the bracket 5, which is convenient for the operation and control of the bracket 5.

[0033] As Figure 3 shown, in some embodiments, a hand wheel 206 is fixedly connected to one end of the threaded rod 201 away from the circular protrusion 205, facilitating the rotation operation of the threaded rod 201.

[0034] As Figure 1 shown, in some embodiments, the bracket 5 is a round rod, which can realize the threaded connection function of the protective cylinder 7.

[0035] As Figure 4 shown, different from the above solution, the protective cylinder 7 is slidably connected to the bracket 5 without the need for threaded connection. Threaded holes 13 are formed in the bracket 5 and the protective cylinder 7, and bolts 14 are installed at the corresponding threaded holes 13 of the bracket 5 and the protective cylinder 7 to fix the position of the protective cylinder 7 after adjustment, and then the position of the protective cylinder 7 is adjusted to adjust the rotation angle of the L-shaped protective frame 1, and then the rotation angle of the roller body 203 is controlled.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
