Description
Technical Field
[0001] The utility model relates to a putty coating device, in particular to a putty coating device for building walls, belonging to the technical field of building construction devices. Background Technique
[0002] During the process of building construction, putty needs to be coated on the building wall. By coating the putty, the wall can be made smooth and flat, laying a good foundation for the subsequent painting. The putty can fill the tiny gaps and unevenness of the wall, making the wall more uniform. Putty coating is mainly divided into two steps. First, the staff will evenly coat the putty on the wall through a coating roller brush. After the putty is coated, a scraper is used to scrape the putty flat.
[0003] However, during the coating process of traditional coating roller brushes, most of them are held by the staff and the roller brush with putty is rolled up and down on the wall. When the roller brush rolls to the corner at the top of the wall, the adjacent wall will block the roller brush, so that the putty cannot be coated at the corner, and thus the wall cannot be coated evenly and comprehensively, which is inconvenient to use. Content of the Utility Model
[0004] The purpose of the utility model is to provide a putty coating device for building walls in order to solve the above problems, which can conveniently coat the putty at the corner at the top of the wall, so that the putty is coated more evenly and comprehensively, and thus is more convenient to use.
[0005] The utility model realizes the above purpose through the following technical solutions. A putty coating device for building walls includes a first support rod. A second support rod is slidably connected to the first support rod. A rotating shaft is rotatably connected to the second support rod. A rotating block is fixedly connected to the rotating shaft. A connecting rod is fixedly connected to the rotating block. A coating structure is arranged on the connecting rod. A clamping structure is arranged on the second support rod. The clamping structure includes a connecting sleeve and a connecting cylinder. Two connecting sleeves are fixedly connected to the second support rod. A connecting cylinder is slidably connected inside the connecting sleeve. One ends of the two connecting cylinders are fixedly connected to the same connecting block. A clamping block is fixedly connected to the connecting block. A clamping groove is arranged at one end of the rotating shaft. One end of the clamping block is clamped with the clamping groove. A limiting structure is arranged on the first support rod.
[0006] Preferably, a second spring is arranged inside the connecting cylinder. One end of the second spring is fixedly connected to the connecting sleeve, and the other end of the second spring is fixedly connected to the connecting block.
[0007] Preferably, the cross section of the clamping groove is in a "cross" shape structure, and the connecting cylinder and the connecting block are in an L-shaped structure.
[0008] Preferably, the smearing structure includes a connecting seat and an inserting shaft. One end of the connecting rod is fixedly connected with the connecting seat. An inserting shaft is rotatably connected to the connecting seat. A smearing roller brush is engaged on the inserting shaft. A stopper is threadedly connected to one end of the inserting shaft, and the stopper abuts against the smearing roller brush.
[0009] Preferably, one end of the inserting shaft is in a cylindrical structure, and the other end of the inserting shaft is in a hexagonal prism structure.
[0010] Preferably, the limiting structure includes a connecting ring and a connecting block. A connecting ring is slidably connected to the first support rod. Two connecting blocks are fixedly connected to the connecting ring. A connecting shaft is rotatably connected to the connecting blocks. Two inserting blocks are slidably connected to the first support rod. A plurality of slots are provided on the second support rod. One end of the inserting block is engaged with an adjacent slot. The other end of the inserting block is fixedly connected with a guiding block, and the connecting shaft is rollingly connected to the guiding block.
[0011] Preferably, a first spring is fixedly connected to the guiding block, and the first spring is fixedly connected to the first support rod.
[0012] Preferably, the middle part of the cross-section of the guiding block is inclined, and the cross-section of one end of the inserting block is in a trapezoidal structure.
[0013] Preferably, the plurality of slots on the same side of the second support rod are linearly and equally spaced, and the cross-section of the connecting block is in a U-shaped structure.
[0014] The beneficial effects of the present utility model are as follows: When in use, putty can adhere to the smearing structure, and then hold the first support rod to move the smearing structure on the wall surface. During the movement of the smearing structure, the putty on the wall surface will be smeared. When it is necessary to smear the putty at the corner at the top of the wall surface, the connecting block can be pulled. The movement of the connecting block will drive the two connecting cylinders to slide inside the two connecting sleeves respectively, so as to play a role in guiding the movement of the connecting block. At the same time, the movement of the connecting block will drive the clamping block to move away from the clamping groove. When the clamping block and the clamping groove are not engaged, the rotating shaft can be rotated. The rotating shaft drives the rotating block to rotate, the rotating block drives the connecting rod to rotate, and the connecting rod drives the smearing structure to rotate. When the rotating shaft rotates 90 degrees, the clamping block is engaged with the clamping groove again. At this time, the rotating shaft cannot continue to rotate. Since the direction of the smearing structure changes after rotating 90 degrees at this time, it will not be blocked by the adjacent wall surface when smearing the corner at the top of the wall surface. Therefore, it is convenient to smear the putty at the corner at the top of the wall surface, so that the putty can be smeared on the wall surface evenly and comprehensively, and thus it is more convenient to use.

Detailed implementation manners
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a device for applying putty on building walls includes a first support rod 1. A second support rod 2 is slidably connected to the first support rod 1. A rotating shaft 4 is rotatably connected to the second support rod 2. A rotating block 5 is fixedly connected to the rotating shaft 4. A connecting rod 7 is fixedly connected to the rotating block 5. An applying structure 8 is provided on the connecting rod 7. A positioning structure 6 is provided on the second support rod 2. The positioning structure 6 includes a connecting sleeve 601 and a connecting cylinder 602. Two connecting sleeves 601 are fixedly connected to the second support rod 2. A connecting cylinder 602 is slidably connected inside the connecting sleeve 601. One end of the two connecting cylinders 602 is fixedly connected to the same connecting block 604. A clamping block 605 is fixedly connected to the connecting block 604. A clamping groove 606 is provided at one end of the rotating shaft 4. One end of the clamping block 605 is engaged with the clamping groove 606. A limiting structure 3 is provided on the first support rod 1.
[0027] As a technical optimization scheme of the present utility model, as Figure 3 shown, a second spring 603 is provided inside the connecting cylinder 602. One end of the second spring 603 is fixedly connected to the connecting sleeve 601, and the other end of the second spring 603 is fixedly connected to the connecting block 604. Therefore, the clamping block 605 can always be engaged with the clamping groove 606.
[0028] As a technical optimization scheme of the present utility model, as Figure 3 and Figure 4 shown, the cross-section of the clamping groove 606 is in a "cross" shape structure, and the connecting cylinder 602 and the connecting block 604 are in an L-shaped structure. Therefore, when the rotating shaft 4 rotates 90 degrees, the clamping block 605 can be engaged with the clamping groove 606 again.
[0029] As a technical optimization scheme of the present utility model, as Figure 1 、 Figure 7 、 Figure 8 and Figure 9 shown, the applying structure 8 includes a connecting seat 801 and an inserting shaft 802. One end of the connecting rod 7 is fixedly connected to the connecting seat 801. An inserting shaft 802 is rotatably connected to the connecting seat 801. An applying roller brush 804 is engaged with the inserting shaft 802. A stop block 803 is threadedly connected to one end of the inserting shaft 802. The stop block 803 abuts against the applying roller brush 804. One end of the inserting shaft 802 is in a cylindrical structure, and the other end of the inserting shaft 802 is in a hexagonal prism structure. Therefore, the applying work of the wall putty can be realized by the applying roller brush 804 with putty sticking to roll on the wall.
[0030] As a technical optimization scheme of the present utility model, as Figure 1 、 Figure 5 and Figure 6As shown in the figure, the limit structure 3 includes a connecting ring 301 and a connecting block 302. The connecting ring 301 is slidably connected to the first support rod 1. Two connecting blocks 302 are fixedly connected to the connecting ring 301. A connecting shaft 303 is rotatably connected to the connecting block 302. Two insertion blocks 305 are slidably connected to the first support rod 1. A plurality of slots 307 are provided on the second support rod 2. One end of the insertion block 305 is engaged with an adjacent slot 307. The other end of the insertion block 305 is fixedly connected to a guiding block 304. The connecting shaft 303 is in rolling connection with the guiding block 304. A first spring 306 is fixedly connected to the guiding block 304. The first spring 306 is fixedly connected to the first support rod 1. The plurality of slots 307 on the same side of the second support rod 2 are linearly and equally spaced. The cross section of the connecting block 302 is in a U-shaped structure. Therefore, the second support rod 2 can be fixed after the position adjustment of the second support rod 2 is completed.
[0031] As a technical optimization scheme of the present invention, as Figure 6 shown in the figure, the middle of the cross section of the guiding block 304 is inclined. The cross section of one end of the insertion block 305 is in a trapezoidal structure. Therefore, while the connecting shaft 303 rolls on the guiding block 304, the insertion block 305 can move away from the slot 307.
[0032] When the utility model is in use, putty can adhere to the spreading roller brush 804 during use. Then, hold the first support rod 1 and roll the spreading roller brush 804 on the wall surface. During the movement of the spreading roller brush 804, putty on the wall surface will be spread. When putty needs to be spread at the corner at the top of the wall surface, the connecting block 604 can be pulled. The movement of the connecting block 604 will drive the two connecting cylinders 602 to slide inside the two connecting sleeves 601 respectively, and the second spring 603 will elongate, thus playing a role in guiding the movement of the connecting block 604. At the same time, the movement of the connecting block 604 will drive the clamping block 605 to move away from the clamping groove 606. When the clamping block 605 is not engaged with the clamping groove 606, the rotating shaft 4 can be rotated. The rotating shaft 4 drives the rotating block 5 to rotate, the rotating block 5 drives the connecting rod 7 to rotate, the connecting rod 7 drives the connecting seat 801 to move, the connecting seat 801 drives the inserting shaft 802 to move, and the inserting shaft 802 drives the spreading roller brush 804 to move. When the rotating shaft 4 rotates 90 degrees, the clamping block 605 is engaged with the clamping groove 606 again. At this time, the rotating shaft 4 cannot continue to rotate. Since the direction of the spreading roller brush 804 changes after rotating 90 degrees, it will not be blocked by the adjacent wall surface when spreading putty at the corner at the top of the wall surface, thus facilitating the spreading of putty at the corner at the top of the wall surface, enabling the putty to be evenly and comprehensively spread on the wall surface, and being more convenient to use. During use, the total length of the first support rod 1 and the second support rod 2 can be adjusted according to the height of the wall surface. During adjustment, the connecting ring 301 can be pulled. The connecting ring 301 drives the two connecting blocks 302 to move, the connecting blocks 302 drive the connecting shaft 303 to move. While the connecting shaft 303 is moving, it is fixed on the guiding block 304. While the connecting shaft 303 is rolling on the guiding block 304, the inserting block 305 will move away from the inserting slot 307, and the first spring 306 will elongate. When one end of the inserting block 305 is not engaged with the inserting slot 307, the second support rod 2 can be pulled to slide on the first support rod 1. After the position of the second support rod 2 is adjusted, the connecting ring 301 can be released to make the two inserting blocks 305 respectively engaged with the other two inserting slots 307. At this time, the first support rod 1 and the second support rod 2 cannot slide, thus completing the adjustment of the total length of the first support rod 1 and the second support rod 2. By adjusting the total length of the first support rod 1 and the second support rod 2, putty can be spread on walls of different heights, thus effectively improving the flexibility of use. When the spreading roller brush 804 needs to be replaced, the stop block 803 can be rotated. After the stop block 803 is twisted off from the inserting shaft 802, the old spreading roller brush 804 can be removed from the inserting shaft 802, and a new spreading roller brush 804 can be sleeved outside the inserting shaft 802. Then, the stop block 803 is screwed to the end of the inserting shaft 802 again. At this time, the replacement of the spreading roller brush 804 is realized. By regularly replacing the spreading roller brush 804, the spreading effect can be guaranteed, making it more convenient to use.
