Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, specifically a quick-release metal sandblasting device. Background Technology

[0002] A metal blasting gun is a handheld tool that uses a high-speed jet of abrasive to impact and treat the surface of metal. It is usually driven by compressed air and mainly consists of a gun body, nozzle, sand inlet, gun handle, switch, air regulating valve, etc. Material is introduced into the gun body through the sand inlet, and the material is ejected from the nozzle when the switch is pressed.

[0003] When performing physical surface treatments, sandblasting equipment is an essential tool. However, existing sandblasting guns are complex to maintain, and if one part breaks down, the entire equipment may need to be replaced, which is time-consuming, labor-intensive, and resource-intensive. Now, a quick-release sandblasting gun has been invented. The quick-release design simplifies the operation steps, and disassembly and assembly can usually be completed in just two steps. This reduces the technical requirements for operators, lightens the labor intensity, and makes the replacement process easier and safer.

[0004] Therefore, it is necessary to design a quick-release metal sandblasting device that is both practical and easy to assemble and disassemble. Utility Model Content

The top of the sand chamber has a sand inlet, and the sand inlet is covered with a sand inlet cover. The bottom left side of the sand chamber has a sand outlet, which is inserted into the silicone sleeve. The bottom right side of the sand chamber has a fixing block, which is fixedly connected to the sand chamber.

[0007] According to the above technical solution, the silicone sleeve has square grooves around its perimeter, and a spherical rotating shaft is fixedly connected inside each set of square grooves. A pin is hinged around the spherical rotating shaft, and the square grooves allow the pin to be embedded inside.

[0008] According to the above technical solution, the outer ring of the silicone sleeve is fitted with an opening cover, the inner wall of the opening cover is threaded and is threadedly connected to the silicone sleeve, and the opening cover has openings around its perimeter, allowing the pin to be moved up and down along the openings.

[0009] According to the above technical solution, the outer ring of the shift post has a nut, and the shift post body is threaded and threadedly connected to the nut to enhance the sealing performance of the silicone sleeve. The outer diameter of the nut is larger than the opening.

[0010] According to the above technical solution, a gun body sand inlet is provided on the top left side of the gun body, and the gun body sand inlet is provided with external threads. A groove is fixedly connected on the top right side of the gun body.

[0011] According to the above technical solution, the fixing block and the groove are inserted into each other, and the inner wall of the silicone sleeve is threaded and threadedly connected to the gun body sand inlet.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] By incorporating a tensioned silicone sleeve, a nut, and an open cap, the lever on the silicone sleeve can be tightly pressed against the outer wall to ensure a tight seal when pulled outwards. Tightening the nut prevents the silicone sleeve from slipping during spray gun movement. The open cap allows the lever to be inserted or secured to the outer ring of the cap with a nut.

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a quick-release metal sandblasting device, including a sand chamber 1 and a silicone sleeve 5. The top of the sand chamber 1 has a sand inlet, and the sand inlet is covered with a sand inlet cover 7. The bottom left side of the sand chamber 1 has a sand outlet 8, and the bottom of the sand outlet 8 is inserted into the silicone sleeve 5. The bottom right side of the sand chamber 1 has a fixing block 11, and the fixing block 11 is fixedly connected to the sand chamber 1.

[0022] The silicone sleeve 5 has square grooves 14 around its perimeter. A spherical rotating shaft 6 is fixedly connected inside each set of square grooves 14. A pin 9 is hinged around the spherical rotating shaft 6. The square grooves 14 allow the pin 9 to be embedded inside.

[0023] The silicone sleeve 5 has an opening cover 3 on its outer ring. The inner wall of the opening cover 3 is threaded and is threadedly connected to the silicone sleeve 5. The opening cover 3 has openings 13 around its perimeter, which allows the lever 9 to be moved up and down along the openings 13.

[0024] The outer ring of the shift post 9 has a nut 4, and the post body of the shift post 9 is threaded and connected to the nut 4 by threads to enhance the sealing of the silicone sleeve 5. The outer diameter of the nut 4 is larger than the port 13.

[0025] The gun body 2 has a sand inlet 10 on the top left side, and the sand inlet 10 is provided with external threads. The gun body 2 has a groove 12 fixedly connected on the top right side.

[0026] The fixing block 11 and the groove 12 are inserted together;

[0027] The inner wall of the silicone sleeve 5 is threaded and is threaded to the gun body sand inlet 10.

[0028] Working principle:

[0029] If the spray gun needs to be assembled, first screw the silicone sleeve 5 onto the gun body sand inlet 10. At this time, the deflector 9 is embedded in the square groove 14 of the silicone sleeve 5. Then screw the opening cap 3 onto the outer ring of the silicone sleeve 5. After the silicone sleeve 5 and the opening 3 are in place, the position of the through 13 corresponds to that of the deflector 9. Pull the deflector 9 out horizontally from the through 13 of the opening cap 3. Then insert the sand outlet 8 into the silicone sleeve 5. Finally, put the nut 4 on the deflector 9 and tighten it to fix the deflector 9. In this way, the nut 4 can ensure the stability of the device and prevent displacement. The silicone sleeve 5 can ensure the airtightness of the device, improve efficiency and extend service life.

[0030] When it is necessary to disassemble the sandblasting gun, first unscrew the nut 4, pull the lever 9 outward in the horizontal direction to separate the sand chamber 1 from it, then push the lever 9 downward to insert it into the opening 13 of the opening cover 3, pull it upward to separate the opening cover 3 from the silicone sleeve 5, and finally unscrew the silicone sleeve 5 from the sand inlet 10 of the gun body. In this way, all parts can be quickly disassembled.
