Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrosion resistance treatment technology, and in particular to a corrosion resistance treatment device for metal-based composite steel plates. Background Technology
[0002] Metal-based composite steel plates are steel plates made of two or more different metal materials through a specific process. Corrosion of metal structures can lead to a decrease in their strength and stiffness, affecting the stability and safety of the structure. Therefore, corrosion-resistant treatment is required during the metal-based composite steel plate manufacturing process to prevent structural damage caused by corrosion. During the corrosion-resistant treatment process, workers use a spray gun to evenly spray corrosion-resistant coating onto the surface of the metal-based composite steel plate. Thus, the spray gun is an important piece of equipment for corrosion-resistant treatment of metal-based composite steel plates.
[0003] Currently, when using existing spray guns, workers hold the gun and aim the nozzle at the board before pulling the trigger to apply the paint. When the distance between the spray gun and the board surface is close, the paint spraying speed and pressure are high, making it easy for the paint to bounce directly onto the operator's hands or sleeves. This requires multiple washes to completely remove the paint from hands or clothing, increasing cleaning costs and personal time investment. To address these issues, we propose a metal-based composite steel plate corrosion-resistant treatment device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrosion-resistant treatment device for metal-based composite steel plates.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A corrosion-resistant treatment device for metal-based composite steel plates includes a spray gun, a nozzle at the front end of the spray gun, a protective plate on the outside of the spray gun, and a first connecting ring connected to the side of the protective plate away from the nozzle. A disassembly mechanism is provided on the inner side of the first connecting ring.
[0007] Preferably, the disassembly mechanism includes a second connecting ring, which is inserted inside the first connecting ring. A collar is connected to the side of the second connecting ring away from the protective plate, and a fixing rod is vertically inserted inside the collar. A pull rod is connected to the top of the fixing rod, and a limiting groove adapted to the fixing rod is opened inside the spray gun.
[0008] Preferably, the collar has symmetrically formed grooves inside, and the inner walls of the grooves are vertically connected to springs, with the top of the springs connected to the pull rod.
[0009] Preferably, the outer surface of the second connecting ring is provided with external threads, and the inner wall of the first connecting ring is provided with internal threads.
[0010] Preferably, the protective plate is connected to a T-shaped sliding strip on its side, and a scraper is fitted on the outer side of the T-shaped sliding strip, and a limiting top plate is connected to the top of the spray gun.
[0011] Preferably, there are two sets of T-shaped sliders, and the two sets of T-shaped sliders are symmetrically distributed about the central axis of the protective plate.
[0012] Preferably, the upper side of the scraper is symmetrically connected with an insertion rod, and the top end of the insertion rod is connected with a rubber block. The edge of the rubber block is set as an arc-shaped structure, and the interior of the limiting top plate is provided with a positioning groove that matches the insertion rod and the rubber block.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This device, equipped with a protective plate and a first connecting ring, can effectively block the rebounding paint during use by working together with the protective plate and the first connecting ring. This effectively prevents the rebounding paint from splashing onto the workers' hands or clothing, thus protecting the workers' hands and clothing and reducing the time that workers need to clean their hands and clothing afterward.
[0015] 2. By setting a limiting top plate and a scraper, after use, the operator can remove the protective plate from the outside of the spray gun and then use the sliding scraper to quickly scrape off the coating adhering to the outer wall of the protective plate, thereby effectively improving the cleaning effect and efficiency of the protective plate.

[0021] 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.
[0022] Reference Figure 1-4 A corrosion-resistant treatment device for metal-based composite steel plates includes a spray gun 1. The front end of the spray gun 1 is provided with a nozzle 2. The connection method between the bottom interface of the spray gun 1 and the paint delivery pipe is existing technology and will not be described in detail here. A protective plate 3 is sleeved on the outside of the spray gun 1, and a first connecting ring 4 is connected to the side of the protective plate 3 away from the nozzle 2. A disassembly mechanism is provided on the inner side of the first connecting ring 4.
[0023] Furthermore, refer to Figure 2 It can be seen that the disassembly mechanism includes a second connecting ring 5, which is inserted inside the first connecting ring 4. A collar 6 is connected to the side of the second connecting ring 5 away from the protective plate 3, and a fixing rod 7 is vertically inserted inside the collar 6. A pulling rod 8 is connected to the top of the fixing rod 7. A limiting groove that matches the fixing rod 7 is opened inside the spray gun 1. Through the cooperation of the fixing rod 7 and the limiting groove, it is convenient for the staff to remove the protective plate 3 from the outside of the spray gun 1 for cleaning after use, so that the paint can always adhere to the outside of the protective plate 3.
[0024] Furthermore, refer to Figure 3 It can be seen that the collar 6 has symmetrical grooves inside, and the inner walls of the grooves are vertically connected to springs 9. The top of the springs 9 is connected to the pull rod 8. Through the connection of the two sets of springs 9, the reliability of the connection between the collar 6 and the spray gun 1 can be effectively guaranteed.
[0025] Furthermore, refer to Figure 3 It can be seen that the outer surface of the second connecting ring 5 is provided with external threads, and the inner wall of the first connecting ring 4 is provided with internal threads. Through the threaded engagement between the first connecting ring 4 and the second connecting ring 5, it is easy for the worker to separate the first connecting ring 4 and the second connecting ring 5, thereby making it easy for the worker to replace the damaged fixing rod 7.
[0026] Furthermore, refer to Figure 3 and Figure 4It can be seen that the protective plate 3 is connected to a T-shaped slide bar 11 on its side, and a scraper 12 is fitted on the outer side of the T-shaped slide bar 11. The top of the spray gun 1 is connected to a limiting top plate 10. During use, the scraper 12 has a T-shaped groove inside that matches the T-shaped slide bar 11. Through the cooperation of the T-shaped groove and the T-shaped slide bar 11, the scraper 12 can be vertically guided so that the workers can clean the outer wall of the protective plate 3 by sliding the scraper 12 up and down. The material of the scraper 12 is similar to the plastic paint scraper in the prior art, so that the outer wall of the protective plate 3 can be cleaned quickly.
[0027] Furthermore, refer to Figure 4 It can be seen that there are two sets of T-shaped sliders 11, and the two sets of T-shaped sliders 11 are symmetrically distributed about the central axis of the protective plate 3. During use, the two sets of T-shaped sliders 11 can effectively ensure the stable sliding of the scraper 12.
[0028] Furthermore, refer to Figure 4 It can be seen that the upper side of the scraper 12 is symmetrically connected with the insertion rod 13, and the top of the insertion rod 13 is connected with the rubber block 14. The edge of the rubber block 14 is set with an arc-shaped structure. The interior of the limiting top plate 10 is provided with a positioning groove that matches the insertion rod 13 and the rubber block 14. During the spraying process of the plate, the operator can insert the insertion rod 13 and the rubber block 14 into the interior of the limiting top plate 10 so that the scraper 12 can fit against the outer wall of the limiting top plate 10, thereby realizing the storage of the scraper 12 and preventing the scraper 12 from moving up and down continuously. Because the rubber block 14 is made of rubber material and the edge of the rubber block 14 is set with an arc shape, when the operator pulls the scraper 12, the rubber block 14 can be pulled out from the interior of the limiting top plate 10 to release the limitation of the scraper 12.
[0029] Working Principle: In use, the operator first connects the interface at the bottom of the spray gun 1 to the paint delivery pipe. Then, the operator holds the spray gun 1 and aims the nozzle 2 at the composite steel plate requiring corrosion resistance treatment. Pulling the trigger sprays the paint from the nozzle 2 onto the outer surface of the steel plate. During spraying, the protective plate 3 effectively prevents paint from splashing onto the operator's hands and sleeves. After spraying, the operator can lift the pull rod 8 to pull the fixing rod 7 out of the outer wall of the spray gun 1. At this point, the operator can push the collar 6 laterally to reconnect the protective plate 3 and the collar. 6. Remove the protective plate 3 from the outside of the spray gun 1. At this time, the worker can put the protective plate 3 along with the collar 6 into the water tank for rinsing. During the rinsing process, the worker can pull the scraper 12, so that the insertion rod 13 and rubber block 14 connected to its top end can be pulled out from the inside of the limiting top plate 10. Then, the worker can slide the scraper 12 to quickly clean the outer wall of the protective plate 3. After cleaning, the worker can insert the insertion rod 13 and rubber block 14 back into the inside of the limiting top plate 10 for limiting and fixing, and reinstall the protective plate 3 on the outside of the spray gun 1 for normal use by the worker in the future. The above is the complete working principle of this utility model.
