[0002] Plasma spraying is a technology for strengthening and modifying the surface of materials. It can give the substrate surface properties such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction and sealing. Plasma spraying technology uses a plasma arc driven by DC electricity as a heat source to heat materials such as ceramics, alloys and metals to a molten or semi-molten state, and then sprays them at high speed onto the pre-treated workpiece surface to form a firmly adhered surface layer.

[0003] The patent CN220619069U discloses a spray gun for plasma spraying. This patent discloses a convenient adjustment technical solution, which solves the problem that the nozzle shape at the front end of the existing spray gun device is fixed, and the flow rate during the nozzle spraying process is difficult to adjust, thus making it difficult for the spray gun device to be adjusted according to different spraying requirements and application scenarios.

[0004] When in use, this device can achieve different spraying effects through the action of the first spray nozzle and the second spray nozzle. However, it is inconvenient to place and fix the spray gun, which reduces the effectiveness of use. Therefore, a spray gun fixing device for plasma spraying equipment is proposed to solve the above problems. Utility Model Content

[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 Figures 1 to 4 The spray gun fixing device of the plasma spraying equipment in this embodiment includes a spray gun body 1 and a handle 2 disposed on the spray gun body 1. A connecting frame 3 is placed on the right side of the spray gun body 1, and the handle 2 extends into the interior of the connecting frame 3. The interior of the connecting frame 3 is provided with a fixing component for fixing the handle 2.

[0022] The fixing assembly includes two limiting plates 12, which are fixedly fitted onto the outer peripheral wall of the handle 2. The inner front and back walls of the connecting frame 3 are fixedly connected to telescopic rods 15. The opposite sides of the two telescopic rods 15 are fixedly connected to fixing frames 13. The handle 2 extends into the interior of the two fixing frames 13. The outer peripheral walls of the two telescopic rods 15 are fitted with springs 16 that are fixedly connected to the connecting frame 3 and the fixing frames 13, respectively.

[0023] Among them, the connecting frame 3 and the fixing frame 13 are both U-shaped frames. The two fixing frames 13 are located between and fit with the two limiting plates 12. The telescopic rod 15 consists of a sleeve and a moving rod. One end of the moving rod passes through and extends into the inside of the sleeve. A limiting block located inside the sleeve is fixedly connected to the outside of the moving rod. A through hole adapted to the moving rod is opened on one side of the sleeve.

[0024] Specifically, pulling the fixed frame 13 causes it to move, compressing the telescopic rod 15 and the spring 16, causing them to retract. The handle 2 is placed between the two fixed frames 13. When the fixed frame 13 is released, the spring 16 pushes the fixed frame 13 back to its original position, so that the handle 2 is located inside the two fixed frames 13, thereby fixing the spray gun body 1.

[0025] Please see Figures 1 to 4 In this embodiment, the connecting frame 3 is provided with a support assembly for supporting the fixed frame 13. The support assembly includes two support plates 11, which are fixedly connected to the right side of the two fixed frames 13 respectively. The inner right wall of the connecting frame 3 is provided with a support groove 10, and both support plates 11 extend into the interior of the support groove 10. Rubber pads 14 are fixedly connected to the inner left and right walls of the two fixed frames 13. The handle 2 is located between the four rubber pads 14.

[0026] The rubber pad 14 and the handle 2 are fitted together, and the support plate 11 and the support groove 10 are slidably connected.

[0027] Specifically, the fixed frame 13 is supported by the sliding connection between the support plate 11 and the support groove 10, thereby improving the stability of the fixed frame 13. The handle 2 is in contact with the rubber pad 14, thereby improving the stability of the spray gun body 1.

[0028] Please see Figures 1 to 4 In this embodiment, the connecting frame 3 is provided with an adjustment component for adjusting the height of the spray gun body 1. The adjustment component includes a fixed plate 5, which is placed on the right side of the connecting frame 3. A movable plate 4 is fixedly connected to the right side of the connecting frame 3. A drive rod 8 is rotatably connected to the top surface of the fixed plate 5 through a bearing. A screw 9 with one end extending into the drive rod 8 is fixedly connected to the bottom surface of the movable plate 4. A sliding groove 7 is provided on the left side of the fixed plate 5. A sliding plate 6 with one end extending into the sliding groove 7 is fixedly connected to the bottom surface of the movable plate 4.

[0029] The fixed plate 5 and the sliding plate 6 are both L-shaped plates. The sliding plate 6 and the sliding groove 7 are slidably connected. The top surface of the drive rod 8 is provided with a threaded hole. The screw 9 extends into the inside of the threaded hole and is threadedly connected to it.

[0030] Specifically, by rotating the drive rod 8, the screw 9 is moved by the moving plate 4 through the threaded connection between the drive rod 8 and the screw 9 and the sliding connection between the sliding plate 6 and the sliding groove 7, so that the height of the spray gun body 1 can be easily adjusted.

[0031] The working principle of the above embodiments is as follows: Pulling the fixed frame 13 moves it, compressing the telescopic rod 15 and spring 16, causing them to retract. The sliding connection between the support plate 11 and the support groove 10 supports the fixed frame 13, improving its stability. The handle 2 is placed between the two fixed frames 13, which are located between the two limiting plates 12. Releasing the fixed frame 13 causes the spring 16 to push it back to its original position, placing the handle 2 inside the two fixed frames 13 and in contact with the rubber pad 14, thus fixing the spray gun body 1. Rotating the drive rod 8, through the threaded connection between the drive rod 8 and the screw 9, and the sliding connection between the sliding plate 6 and the sliding groove 7, causes the screw 9 to move via the moving plate 4, allowing for convenient adjustment of the spray gun body 1's height.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
