Description

Technical Field

[0001] This utility model relates to the field of rust prevention treatment through the cover, and in particular to a spraying equipment for rust prevention treatment of machine base sealing through the cover. Background Technology

[0002] The sealing cover on the machine base is a metal component used for sealing. However, metal components are prone to rust in humid or corrosive environments, which affects the service life of the equipment. The traditional way to deal with this is to spray paint its surface with a spray gun.

[0003] Chinese Patent Publication No. CN 218132634 U describes "a rust-preventive spraying device". Through the connection of a connecting rod and a screw ring, and the abutting connection between the screw ring and a sliding plate, the sliding plate changes position on the spray gun via an adjusting groove. The screw ring supports the sliding plate's position. Through the connection of the sliding groove and the sliding plate, and the connection of a retaining ring and abutting ring, the position of the retaining ring on the sliding plate changes. Through the connection of a support spring and a spring plate, the spring plate constrains the connection between the air pipe and the spray gun, achieving a limiting support effect for their connection angle.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] Its metal frame structure means that when it restricts the airway, it cannot flexibly support and adjust the bending of the airway, resulting in relatively poor protection.

[0006] Therefore, it is necessary to provide a new spraying equipment for rust prevention treatment of machine base sealing cover to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a spraying device for rust prevention treatment of machine base sealing cover.

[0009] The protective component includes a rubber tube, an air supply pipe connected to the connecting nozzle passing through the inside of the rubber tube, a first positioning ring being sleeved and fixed at one end of the rubber tube, the first positioning ring being detachably connected to the connecting nozzle, and a second positioning ring being sleeved and fixed at the other end.

[0010] The anti-pull assembly comprises multiple anti-pull assemblies, all located inside the second positioning ring and arranged in a ring shape. Each assembly includes a rotating arm rotatably connected to the second positioning ring, with a fixing block fixed to the other end of the rotating arm. A rubber block that can contact the gas supply pipe is adhered and fixed to the other side of the fixing block.

[0011] Preferably, the outer circumferential wall of the connecting nozzle is provided with an annular groove, and the first positioning ring is sleeved and fixed on the connecting nozzle. The inner circumferential wall of the first positioning ring also has an annular rail embedded in the annular groove.

[0012] The first positioning ring is also threaded with a tightening bolt on its circumference. The tightening bolt can abut against the connecting mouth, so that the first positioning ring is fixed on the connecting mouth.

[0013] Preferably, a baffle is welded and fixed to the outer circumference of the first positioning ring, and one end of the rubber tube abuts against the baffle.

[0014] Preferably, a spring is also embedded and fixed inside the rubber tube.

[0015] Preferably, the inner circumferential wall of the second positioning ring is provided with multiple grooves;

[0016] One end of the rotating arm is rotatably connected to a positioning shaft, which is fixed inside the groove. A torsion spring that abuts against the rotating arm is also sleeved on the positioning shaft.

[0017] Preferably, the rubber block is fan-shaped, and its circumferential surface can contact the gas supply pipe.

[0018] Compared with related technologies, the spraying equipment for rust prevention treatment of machine base sealing cover provided by this utility model has the following beneficial effects:

[0019] This utility model provides a spraying device for rust prevention treatment of a machine base with a sealed cover. The air supply pipe can pass through a rubber tube, which protects the connection. At the same time, a spring is installed inside the rubber tube to enhance its pressure resistance. This allows for flexible support and adjustment according to the curvature of the air pipe itself, limiting the bending range of the pipe and enhancing the protection effect of the pipe.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5This utility model provides a spraying device for rust prevention treatment of a machine base sealing cover. The spraying device includes a gun body 1, a handle 11 fixed on the gun body 1, and a connecting nozzle 12 for connecting to an air supply pipe at the lower end of the handle 11. It also includes:

[0032] The protective component 2 includes a rubber tube 25, and an air supply pipe connected to the connecting nozzle 12 passes through the inside of the rubber tube 25. One end of the rubber tube 25 is fitted with a first positioning ring 21, which is detachably connected to the connecting nozzle 12, while the other end is fitted with a second positioning ring 27.

[0033] Anti-pull assembly 3, there are multiple anti-pull assemblies 3, all located inside the second positioning ring 27 and distributed in a ring shape, including a rotating arm 31 rotatably connected to the second positioning ring 27, a fixing block 34 fixed at the other end of the rotating arm 31, and a rubber block 35 that can contact the gas supply pipe is glued and fixed on the other side of the fixing block 34.

[0034] It should be noted that: in this device, a protective component 2 is installed on the connecting nozzle 12 to further protect the connection area between the gas supply pipe and the connecting nozzle 12, which can prevent the gas supply pipe from being damaged due to excessive bending.

[0035] In the protective component 2, the rubber tube 25 is the main protective structure. One end of the rubber tube 25 is fixed to the connecting nozzle 12 by the first positioning ring 21. The air supply pipe can pass through the rubber tube 25. Therefore, when using a spray gun for spraying, the bending range of the air supply pipe can be limited by the rubber tube 25.

[0036] An anti-pull assembly 3 is also provided inside the second positioning ring 27. The anti-pull assembly 3 can contact the outer wall of the air supply pipe. Therefore, when using the spray gun and the air supply pipe is in a taut state (if the air supply pipe is too short, it may be necessary to pull the pipe to increase the working range), the anti-pull assembly 3 can be used to further reinforce the connection between the air supply pipe and the connecting nozzle 12 to prevent it from falling off due to pulling.

[0037] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The outer circumferential wall of the connecting nozzle 12 is provided with an annular groove 13, and the first positioning ring 21 is sleeved and fixed on the connecting nozzle 12. The inner circumferential wall of the first positioning ring 21 also has an annular rail 22 embedded in the annular groove 13.

[0038] The first positioning ring 21 is also threaded with a tightening bolt 23 on its circumferential surface. The tightening bolt 23 can press against the connecting mouth 12, so that the first positioning ring 21 is fixed on the connecting mouth 12.

[0039] It should be noted that: for the installation of the protective component 2, the first positioning ring 21 can be directly fitted onto the connecting nozzle 12. There is also a ring groove 13 and a ring rail 22 between the two. After the ring groove 13 is embedded in the ring rail 22, the stability between the two can be enhanced. At the same time, a tightening bolt 23 is also provided on the first positioning ring 21. The tightening bolt 23 can abut against the connecting nozzle 12 to achieve the positioning of the first positioning ring 21.

[0040] In the embodiments of this utility model, please refer to Figure 3 A baffle 24 is welded and fixed to the outer circumference of the first positioning ring 21. One end of the rubber tube 25 is pressed against the baffle 24, and a spring 26 is embedded and fixed inside the rubber tube 25.

[0041] It should be noted that a spring 26 is inserted inside the rubber tube 25, which can further increase the rigidity of the rubber tube 25 itself, thus providing a better constraint effect on the gas supply pipeline.

[0042] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The inner circumferential wall of the second positioning ring 27 is provided with multiple grooves 28;

[0043] One end of the rotating arm 31 is rotatably connected to a positioning shaft 32, which is fixed inside the groove 28. A torsion spring 33 is also sleeved on the positioning shaft 32 to press against the rotating arm 31.

[0044] Among them, the rubber block 35 is fan-shaped, and its circumference can contact the gas supply pipe.

[0045] It should be noted that the rotating arm 31 is rotatably installed inside the second positioning ring 27 via the positioning shaft 32. At the same time, a torsion spring 33 is added so that after the air supply pipe is inserted into the rubber tube 25, the rubber block 35 can contact the air supply pipe. The friction between the two prevents the air supply pipe from being pulled off the connecting nozzle 12.

[0046] It should also be noted that the spring force of the torsion spring 33 needs to be adjusted appropriately to ensure that the rubber tube 25 can contact the gas supply pipe, but will not exert strong pressure on it, so as not to affect the normal gas supply of the pipe.

[0047] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0048] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
