Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of paint spraying protection, and in particular relates to an auxiliary device for spraying paint on the inside of a transformer pipe joint for protection. Background Art
[0002] During the production process, pipe fittings are often spray-painted to improve their corrosion resistance and aesthetics. However, during the painting process, paint can easily enter the interior of the fitting, causing internal contamination and affecting its performance. Furthermore, traditional protection methods are often ineffective, complex, and inefficient.
[0003] Currently, a titanium alloy metal box pipe joint paint protection tool, with announcement number CN216368717U, is available on the market. It comprises a titanium alloy metal box with a pipe joint assembly mounted on its side; the pipe joint assembly includes a pipe joint with a fixed threaded cap attached to one side; and a protective cone attached to the fixed threaded cap. This titanium alloy metal box pipe joint paint protection tool can reduce rework and increase product painting efficiency. It eliminates the need for end surface grinding, ensuring surface roughness.
[0004] However, there is also a problem: the device can only protect the end face and cannot protect the inside of the pipe joint. Moreover, the device is fixed by bolts, which makes it very troublesome to disassemble. Utility Model Content
[0005] This solution provides a transformer pipe joint internal paint protection auxiliary device to solve the problem of troublesome assembly and disassembly.
[0006] This solution provides an auxiliary device for internal paint spraying protection of a transformer pipe joint, including a protective plate: the protective plate is used to block the inner wall of the pipe joint; a fixing mechanism: the fixing mechanism is a semi-elliptical iron ring, the iron ring is fixedly connected to the protective plate, and the iron ring cooperates with the inner wall of the pipe joint.
[0007] The principle of this solution is that when in use, the iron ring of the fixing mechanism is inserted into the pipe joint. Due to the transitional fit of the iron ring and the pipe joint, the iron ring is fully inserted and just stuck inside the pipe joint. The friction between the iron ring and the pipe joint fixes the protective plate, and the protective plate is now close to the end face of the pipe joint, so that the paint will not be sprayed on the inside of the pipe joint. Removal is also very convenient, just pull out the protective plate with force.
[0008] The beneficial effects of this solution are: the invention has a simple structure, is easy to manufacture and use, is convenient to operate, and can quickly install and remove the protective cover.
[0009] Furthermore, the invention also includes a handle, which is fixedly connected to the protective ring, and the handle and the iron ring are located on both sides of the protective plate. The handle is convenient for the operator to take, thereby improving the convenience of operation.
[0010] Furthermore, the iron ring is coated with a protective layer made of silicone. During installation and removal, the iron ring will inevitably collide and rub against the inside of the pipe joint, which can easily cause damage to the pipe joint. Coating the iron ring with a layer of silicone can effectively reduce the damage caused by friction.
[0011] Furthermore, the invention further comprises a magnetic ring, which is fixedly connected to the protective plate and cooperates with the outer wall of the pipe joint. When the protective plate is in close contact with the end face of the pipe joint, the outer wall of the pipe joint just contacts the inner wall of the magnetic ring, so that the magnetic ring attracts the pipe joint and improves the stability of the protective plate.
[0012] Furthermore, the invention also includes a sealing layer, which is fixedly connected to the protective plate and matched with the pipe joint. The sealing layer can increase the sealing between the protective plate and the pipe joint and prevent paint from penetrating into the pipe joint. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a structural diagram of a transformer pipe joint internal paint protection auxiliary device.
[0014] Figure 2 This is a front view of an auxiliary device for spraying paint inside a transformer pipe joint for protection.
[0015] The accompanying drawings in the specification include: 1. protective plate; 2. fixing mechanism; 3. handle. DETAILED DESCRIPTION
[0016] As attached Figure 1 、 Figure 2 As shown:
[0017] This solution provides an auxiliary device for internal paint spraying protection of transformer pipe joints, including a protective plate 1, a fixing mechanism 2 and a handle 3. The protective plate 1 is used to block the inner wall of the pipe joint, and the protective plate 1 is made of iron plate. The fixing mechanism 2 is composed of a semi-elliptical iron ring, and the maximum width of the iron ring is slightly larger than the diameter of the inner wall of the pipe joint. The iron ring is fixedly connected to the protective plate 1. The handle 3 is fixedly connected to the protective ring, and the handle 3 and the iron ring are located on both sides of the protective plate 1. The handle 3 is convenient for the operator to pick up, which improves the convenience of operation. The surface of the iron ring is wrapped with a protective layer, and the protective layer is a protective layer made of silicone. The iron ring will inevitably collide and rub with the inside of the pipe joint during loading and unloading, which can easily cause damage to the inside of the pipe joint. Wrapping a layer of silicone on the surface of the iron ring can effectively reduce the damage caused by friction.
[0018] It also includes a magnetic ring, which is fixedly connected to the protective plate 1. When the protective plate 1 is tightly attached to the end face of the pipe joint, the outer wall of the pipe joint just contacts the inner wall of the magnetic ring, so that the magnetic ring absorbs the pipe joint and improves the stability of the protective plate 1.
[0019] The pipe joint is fixedly connected to the protective plate 1 and aligned with the pipe joint end face. The sealing layer can increase the sealing performance between the protective plate 1 and the pipe joint and prevent paint from penetrating into the pipe joint.
[0020] The principle of this solution is that when in use, the operator grasps the handle 3 and inserts the iron ring of the fixing mechanism 2 into the pipe joint. Due to the transitional fit of the iron ring and the pipe joint, the iron ring fits snugly inside the pipe joint when fully inserted. The friction between the iron ring and the pipe joint secures the protective plate 1, which then abuts the end face of the pipe joint, preventing spray paint from entering the pipe joint. Removal is also very convenient: simply pull the handle 3 firmly to pull out the protective plate 1.
[0021] The beneficial effects of this solution are: 1. This solution has a good protective effect and can effectively prevent paint from entering the interior of the pipe joint, thereby ensuring the performance of the pipe joint.
[0022] 2. This solution can reduce the labor intensity of on-site spray painters. By using tooling in conjunction with pipe joints, the amount of grinding work that was originally increased due to paint contamination on the pipe joints can be greatly reduced.
[0023] 3. This solution has a simple structure, is easy to manufacture and use, is easy to operate, and can quickly install and remove the protective cover.
[0024] 4. This solution has high adaptability, and the tooling has an adjustable function, which can be applied to a variety of pipe joints.
[0025] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
