Description

Technical Field

[0001] This utility model relates to the field of paint scraper technology, and in particular to a paint scraper for building decoration. Background Technology

[0002] Painting walls is an essential part of building decoration, which requires scraping off plaster and removing residual paint. During this process, workers need to use a paint scraper to assist in the work.

[0003] Currently, existing paint scrapers mainly consist of a blade and a handle. Because the blades are generally thin, their edges are quite sharp. After use, when workers put the paint scraper directly into their tool bags, the sharp blade can tear the tool bags, exposing the blade and easily causing cuts to workers. Therefore, there is a significant safety hazard during use. To address this issue, we propose a paint scraper for building decoration. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a paint scraper for building decoration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A paint scraper for building decoration includes a handle, a blade connected to the front end of the handle, a protective frame fitted on the outer side of the blade, a connecting rod connected to the side of the protective frame, a connecting groove adapted to the connecting rod inside the handle, a guide plate connected to the end of the connecting rod, and the outer wall of the guide plate and the inner wall of the connecting groove being tightly fitted together.

[0007] Preferably, the protective frame has two sets of extension plates distributed on its side, and the distance between the extension plates is greater than the lateral length of the handle.

[0008] Preferably, the handle has an insertion slot at its top, and an insertion rod is inserted into the insertion slot. The top of the insertion rod is connected to a pull block, and the connecting rod has two sets of limiting slots that are adapted to the insertion rod.

[0009] Preferably, a connecting spring is symmetrically connected to the lower part of the pull block, and the other end of the connecting spring is connected to the handle.

[0010] Preferably, the insertion rod has symmetrically formed grooves on its side, and a guide block is inserted inside the groove, the guide block being connected to the inner wall of the insertion groove.

[0011] Preferably, scrapers are symmetrically distributed at the upper and lower ends of the inner wall of the protective frame, and a disassembly mechanism is provided on the side where the scrapers are far apart from each other.

[0012] Preferably, the disassembly mechanism includes a connecting plate connected to the side of the scraper, a connecting block being threaded onto the outer side of the connecting plate, and the interior of the connecting block being connected to a protective frame by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device, equipped with a protective frame and connecting rod, can protect the tip corner of the blade after use by working together with the protective frame and connecting rod. This effectively prevents the blade from scratching the tool bag when placed and also prevents workers from being accidentally injured by the blade's edge, thus effectively improving the safety of the device during use.

[0015] 2. This device, equipped with scrapers and connecting plates, allows workers to scrape off residual paint from the outer surface of the blades by using two sets of scrapers on its inner side as the protective frame is pulled horizontally. This prevents the paint from adhering and affecting the use of the device. The connecting plates and connecting blocks also make it easy for workers to replace damaged scrapers in a timely manner.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A paint scraper for building decoration includes a handle 1, a blade 2 connected to the front end of the handle 1, and a protective frame 3 sleeved on the outer side of the blade 2. A connecting rod 4 is connected to the side of the protective frame 3. A connecting groove 5 adapted to the connecting rod 4 is opened inside the handle 1. A guide plate 14 is connected to the end of the connecting rod 4. The outer wall of the guide plate 14 and the inner wall of the connecting groove 5 are tightly fitted. By abutting against the inner wall of the connecting groove 5, the damping of the protective frame 3 when it moves can be increased, thereby initially limiting the pull-out protective frame 3.

[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that there are two sets of extension plates 10 distributed on the side of the protective frame 3, and the distance between the extension plates 10 is greater than the lateral length of the handle 1. By setting the two sets of extension plates 10, the protection area of ​​the blade 2 corners can be effectively guaranteed. Since the distance between the extension plates 10 is large, when the protective frame 3 is stored in the front end of the handle 1, the two sets of extension plates 10 can be moved to the side of the handle 1 to realize the storage of the extension plates 10.

[0025] Furthermore, refer to Figure 2 , Figure 3 and Figure 4 It can be seen that an insertion slot is provided above the handle 1, and an insertion rod 6 is inserted into the insertion slot. The top of the insertion rod 6 is connected to a pull block 7. The connecting rod 4 has two sets of limiting slots that are compatible with the insertion rod 6. When the insertion rod 6 is inserted into the limiting slot near the protective frame 3, the connecting rod 4 can be stored in the connecting slot 5, which makes it convenient for the staff to use the device normally. When the insertion rod 6 is inserted into the limiting slot away from the protective frame 3, the protective frame 3 can be located at the front end of the blade 2, which makes it convenient for the staff to move the device.

[0026] Furthermore, refer to Figure 4 and Figure 5 It can be seen that a connecting spring 8 is symmetrically connected to the lower part of the pull block 7, and the other end of the connecting spring 8 is connected to the handle 1. In use, the connection between the pull block 7 and the handle 1 can be realized by setting the connecting spring 8, which can effectively prevent the insertion rod 6 from being lost after being pulled out, and can effectively ensure the tightness of the insertion rod 6 when it is inserted into the limiting groove.

[0027] Furthermore, refer to Figure 5It can be seen that the insertion rod 6 has symmetrically opened sliding grooves on its side, and a guide block 9 is inserted inside the sliding groove. The guide block 9 is connected to the inner wall of the insertion groove. In use, the sliding groove and the guide block 9 cooperate with each other to vertically guide the insertion rod 6 during the stretching process, so as to ensure the stability of the insertion rod 6 during the up and down movement.

[0028] Furthermore, refer to Figure 4 It can be seen that scrapers 11 are symmetrically distributed at the upper and lower ends of the inner wall of the protective frame 3, and a disassembly mechanism is provided on the side of the scrapers 11 that are far apart from each other. During use, the scrapers 11 can be used to clean the outer wall of the blade 2 while pulling the protective frame 3, so as to prevent paint residue on the outer wall of the blade 2.

[0029] Furthermore, refer to Figure 1 and Figure 4 It can be seen that the disassembly mechanism includes a connecting plate 12, which is connected to the side of the scraper 11. A connecting block 13 is connected to the outer side of the connecting plate 12, and the interior of the connecting block 13 is connected to the protective frame 3 by bolts. Through the cooperation of the connecting plate 12 and the connecting block 13, it is convenient for the staff to disassemble and replace the scraper 11 that cannot perform scraping work in a timely manner, thereby effectively ensuring the cleaning effect of the blade 2.

[0030] Working Principle: When using this utility model, the operator can first pull the pulling block 7 upwards, thereby moving the insertion rod 6 upwards simultaneously. At this time, the lower side of the insertion rod 6 can be pulled out from the inside of the connecting rod 4 to release the restriction on the connecting rod 4. Then, the operator can manually push the protective frame 3, thereby moving the connecting rod 4 connected to its side and storing it inside the connecting groove 5. When the protective frame 3 is pushed to the front end of the handle 1, the position of the insertion rod 6 corresponds to the position of another set of limiting grooves inside the connecting rod 4, thereby limiting the insertion rod 6. Then, the operator can hold the handle 1 to perform scraping and painting operations. After the operation is completed, the operator can pull the pulling block 7 again, thereby pulling the protective frame 3 to move it to the front end of the blade 2, and using the insertion rod 6 to limit the protective frame 3, thereby protecting the edges and corners of the blade 2 and effectively preventing accidental injury to the operator from the edges and corners of the blade 2. The above is the complete working principle of this utility model.
