[0003] In order to solve the above technical problems, the patent file with the publication number CN219654648U discloses an oil pipe variable buckle joint. The large diameter section of the oil pipe variable buckle joint is provided with an internal thread, the small diameter section is provided with an external thread, an external boss is arranged between the small diameter section and the end of the variable diameter, four insertion holes are arranged on the external boss in a circumferentially uniform manner, and the side surface of the external boss is sleeved with an asbestos buffer pad. This technical solution can avoid rigidly screwing and clamping the pipe fitting and the variable buckle joint by arranging the asbestos buffer pad, thereby reducing the damage to the thread tail section.

[0004] In order to solve the problem that the asbestos buffer pad is easy to fall off, a ring groove can be arranged on the oil pipe variable buckle joint so that the asbestos buffer pad is located in the ring. However, this method will increase the production cost of the oil pipe variable buckle joint, and the ring groove will damage the anticorrosion layer of the oil pipe variable buckle joint that has been treated. Based on the above content, an oil pipe variable buckle is needed to solve the problem that the asbestos buffer pad is easy to fall off without changing the production process of the oil pipe variable buckle. UTILITY MODEL CONTENT

[0005] The main purpose of the utility model is to provide an oil pipe variable buckle that can solve the problem that the asbestos buffer pad is easy to fall off without changing the production process.

[0006] In order to achieve the above purpose, the technical solution provided by the utility model is as follows:

[0007] The utility model provides an oil pipe variable buckle, including variable buckle body, the variable buckle body has the little end and the big end, is provided with the outer boss between the little end and the big end, the little end of variable buckle body is equipped with the asbestos buffer pad, the little end of variable buckle body between asbestos buffer pad and the outer boss is equipped with the connecting piece, the connecting piece includes the collar, the side of collar is fixed with a plurality of elastic sheets towards the outer boss, the outer boss is located between a plurality of elastic sheets, a plurality of elastic sheets are clamped to the outer boss, the side of elastic rod is fixed with the flange towards asbestos buffer pad, the asbestos buffer pad is located between the flange and the collar, the flange blocks asbestos buffer pad, and the end of elastic rod is inclined to the outside direction of variable buckle body and forms the inclined part away from the collar.

[0008] Specifically, the connecting piece is made of plastic material, and the elastic sheet, the collar, the elastic rod and the flange are integrally formed.

[0009] Specifically, the outer diameter of the collar is greater than the outer diameter of the outer boss.

[0010] Specifically, the end of the elastic sheet away from the collar is inclined to the center direction of the variable buckle body, the end of the elastic sheet away from the collar is integrally formed with a guide portion, and the end of the guide portion away from the elastic sheet is inclined to the outside direction of the variable buckle body.

[0011] Specifically, the part of the elastic rod between the inclined part and the collar is in contact with the outer edge of the asbestos buffer pad on the side towards the center of the variable buckle body.

[0012] Specifically, the end of the elastic sheet away from the collar is machined with an arc surface abutting the outer edge of the outer boss, and the arc surface is machined with anti-skid lines.

[0013] Specifically, the flange is in an arc structure.

[0014] Specifically, the plurality of elastic sheets and the plurality of elastic rods are circumferentially distributed according to the axis of the collar.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] 1. The elastic sheet clamps the outer boss, the elastic rod and the flange limit the asbestos buffer pad in two directions, forming multidirectional constraint, without slotting on the variable buckle body or changing the production process, avoiding the damage of the corrosion-resistant layer.

[0017] 2. The inclined part of the elastic rod provides guidance when the pipe fitting is installed, preventing the elastic rod from being extruded, deformed or broken, and ensuring that the connecting piece can be reused.

[0018] 3、The connecting piece is made of plastic material in one piece, and the elastic sheet and the elastic rod are designed to be uniformly distributed in the circumference to simplify the installation process, and only need to be sleeved to complete the fixing. The guide part at the end of the elastic sheet and the arc anti-skid design enhance the fit and friction with the outer boss, reducing the risk of the connecting piece slipping during installation. The double action of the anti-skid pattern and the clamping force of the elastic sheet ensures that the connecting piece can still stably fix the asbestos cushion under complex working conditions such as vibration and impact.

[0019] 4、The connecting piece made of plastic material is lightweight and corrosion-resistant, reducing the overall weight and production cost. No additional processing of the body (such as opening a ring groove) is required, and it is directly compatible with existing production processes, reducing equipment modification costs.

[0020] 5、The design of the outer diameter of the sleeve ring being larger than the outer boss provides a larger coverage area for the asbestos cushion, enhancing the cushioning effect while being compatible with different specifications of the body. When the pipe is connected to the body, the elastic rod can elastically deform, allowing the asbestos cushion to displace moderately when under pressure, avoiding wear caused by rigid friction.
