TECHNICAL FIELD

[0001] The utility model relates to a powder spraying process technical field, especially a powder spraying process protective sleeve. BACKGROUND

[0002] With the development of science and technology, more and more products need to be sprayed, and the local pipe does not need to be sprayed in the powder spraying product, so the part of the circular pipe that does not need to be sprayed needs to be protected in advance, for example, the muffler needs to be sprayed, but part of the circular pipe does not need to be sprayed, so the part of the circular pipe needs to be protected. The existing protection methods are as follows: 1. The silica gel sleeve is sleeved on the circular pipe for protection, which is difficult to operate, cannot be recycled or used multiple times, and has high cost; 2. The circular pipe is wrapped with rubber paper or newspaper, which requires more manpower, cannot be recycled or used multiple times, and has high cost.

[0003] Therefore, the above-mentioned defects must be improved. UTILITY MODEL CONTENT

[0004] The utility model solves the technical problem of providing a powder spraying process protective sleeve to solve the problem in the background art.

[0005] In order to solve the above technical problems, the technical scheme of the utility model is as follows:

[0006] A powder spraying process protective sleeve, comprising a circular pipe, the rear end of the circular pipe is provided with an end cover for sealing, the front end of the outer wall of the circular pipe is provided with an annular protrusion, the front end of the inner wall of the circular pipe is provided with an annular mounting groove corresponding to the annular protrusion, the circular pipe, the end cover and the annular protrusion are all made of metal material, and a high-temperature-resistant sealing ring is arranged on the annular mounting groove.

[0007] Further, the circular pipe, the end cover and the annular protrusion are integrally processed and formed.

[0008] Further, the material of the circular pipe, the end cover and the annular protrusion is stainless steel.

[0009] Further, the annular protrusion is a semicircular protrusion.

[0010] Further, the high-temperature-resistant sealing ring is an O-ring.

[0011] The utility model has the advantages of:

[0012] By adopting the above technical solution, a circular tube with an end cap structure is used. An annular mounting groove is set on the circular tube, and a high-temperature resistant sealing ring is placed in the annular mounting groove. The high-temperature resistant sealing ring can also prevent the circular tube behind the high-temperature resistant sealing ring from being affected by the powder spraying process after the sleeve. In this way, the overall structure is stable and the sleeve and tube pulling methods are convenient. Only a small amount of manpower is needed for operation, and it can be recycled or reused multiple times, thereby reducing the overall production cost. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Reference Figs. 1 to 3 The present invention provides a protective sleeve for powder coating process, including a round tube 1, an end cap 3 for sealing at the rear end of the round tube 1, an annular protrusion 2 on the front end of the outer wall of the round tube 1, and an annular mounting groove 5 corresponding to the annular protrusion 2 on the front end of the inner wall of the round tube 1. The round tube 1, the end cap 3 and the annular protrusion 2 are all made of metal, and a high-temperature resistant sealing ring 4 is provided on the annular mounting groove 5.

[0020] This technical solution adopts a structure of a round tube 1 with an end cap 3, and sets an annular mounting groove 5 on the round tube 1. A high-temperature resistant sealing ring 4 is placed in the annular mounting groove 5. The high-temperature resistant sealing ring 4 can also prevent the round pipe behind the high-temperature resistant sealing ring 4 from being affected by the powder spraying process after the sleeve is installed. In this way, the overall structure is stable and the sleeve and pull-out methods are convenient. This requires only a small amount of manual operation and can be recycled or reused multiple times, thereby reducing the overall production cost.

[0021] The powder spraying process protection sleeve can be used for protecting the circular pipe of the muffler, and can also be used in products with a circular pipe which does not need to be sprayed, so that the use performance of the powder spraying process protection sleeve is improved.

[0022] In the preferred embodiment of the technical solution, the inner diameter of the circular pipe 1 is 9.70 mm, the thicknesses of the circular pipe 1 and the end cover 3 are both 0.80 mm, the radius of the semicircular protrusion is 1.50 mm, and the distance between the center of the semicircular protrusion and the front end face of the circular pipe 1 is 5 mm. Of course, the actual specific size can be adjusted according to the use requirements, and is not limited to the size in the preferred embodiment.

[0023] For example, in some embodiments, the circular pipe 1, the end cover 3 and the annular protrusion 2 are integrally machined and formed. In this way, the stability of the overall structure can be ensured, the sleeving and unplugging are facilitated, the labor cost is reduced, and the powder spraying efficiency is improved. The tail end of the outer wall of the circular pipe 1 can be provided with multiple evenly distributed anti-skid rings, so that the circular pipe 1 is not easy to slip when held by hand, and the sleeving and unplugging are facilitated.

[0024] For example, in some embodiments, the circular pipe 1, the end cover 3 and the annular protrusion 2 are made of stainless steel. In this way, the structure quality is good, the product is not easy to deform after multiple or cyclic uses, the use is stable, and the powder spraying effect is ensured.

[0025] For example, in some embodiments, the annular protrusion 2 is a semicircular protrusion. In this way, the high-temperature-resistant sealing ring 4 can be tightly attached to the corresponding circular pipe during the sleeving and unplugging process.

[0026] For example, in some embodiments, the high-temperature-resistant sealing ring 4 is an O-ring. In this way, the O-ring can be tightly attached to the corresponding circular pipe during the sleeving and unplugging process.

[0027] In summary, the utility model adopts the circular pipe plus end cover structure, sets the annular mounting groove on the circular pipe, and places the high-temperature-resistant sealing ring in the annular mounting groove. The high-temperature-resistant sealing ring can also avoid the influence of the powder spraying process on the circular pipe at the rear end of the high-temperature-resistant sealing ring after sleeving. In this way, the overall structure is stable, the sleeving and unplugging are facilitated, a small amount of manpower is required for operation, the product can be cyclically or repeatedly used, and the overall production cost is reduced.

[0028] The embodiments of the present application are described in detail in combination with the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
