Abstract
Description
Technical Field
[0001] The utility model relates to a high-strength pipe fitting, belonging to the technical field of pipe fittings. Background Technique
[0002] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow division, sealing, and support. In order to transport liquids or gases, various pipes must be used. Except for straight pipes made of steel pipes, elbows must be used when the pipe bends, reducers must be used when the pipe diameter changes, tees must be used when bifurcating, flanges must be used when connecting pipe joints, and various valves must be used to achieve the purpose of opening the transported medium. In order to reduce the influence of thermal expansion and cold contraction or frequent vibration on the pipeline system, expansion joints must also be used. In addition, on the pipeline, there are also various joints, plugs, etc. connected to various instruments and meters. We are used to collectively referring to other fittings in the pipeline system except straight pipes as pipe fittings.
[0003] During the use of existing pipe fittings, there are still some problems. When the water pressure inside the pipe fitting is relatively large, it is easy to generate a huge impact force on the inner wall of the pipe fitting. After long-term use, it will cause damage to the inner wall of the pipe fitting, resulting in a reduction in its service life. And when connecting pipe fittings, it is generally connected by a threaded connection method, but it is easy to leak water at the threaded connection during use, thus affecting the normal use of the pipe fitting. Content of the Utility Model
[0004] The purpose of the utility model is to provide a high-strength pipe fitting. The structure of the utility model is simple and convenient to use, which can enhance the strength of the inner wall of the pipe fitting, thus preventing it from being damaged, and can prevent water leakage at the connection of the pipe fitting, so as to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A high-strength pipe fitting includes a pipe fitting body. A moving hole is opened in the inner wall of the pipe fitting body. A nylon rod is slidably clamped inside the moving hole. A buffer cover is fixedly connected to the outside of the nylon rod. A shock-absorbing spring is fixedly connected to the top of the buffer cover.
[0007] Further, an adapter ring is slidably connected to the outside of the pipe fitting body. A hidden groove is opened inside the adapter ring. A return spring is fixedly connected to the inner wall of the hidden groove. A sealing cover is fixedly connected to the bottom of the return spring. A threaded pipe is fixedly connected to the outside of the adapter ring. A screw rod is threadedly connected inside the threaded pipe. A rotating cover is fixedly connected to the top of the screw rod. An extrusion rod is fixedly connected to the bottom of the screw rod.
[0008] Further, the moving holes are evenly distributed in the inner wall of the pipe fitting body, and the buffer cover is movably connected to the inside of the pipe fitting body through nylon rods.
[0009] Further, the buffer covers are symmetrically distributed inside the pipe fitting body, and the tops of the shock-absorbing springs are fixedly connected to the inner wall of the pipe fitting body.
[0010] Further, the reset springs are symmetrically distributed between the sealing cover and the inner wall of the hidden groove, and the sealing cover is located inside the hidden groove.
[0011] Further, the sealing covers are symmetrically distributed outside the pipe fitting body, and the screw rod is threadedly connected to the inside of the threaded pipe through the rotating cover.
[0012] Further, the extrusion rod passes through the inside of the connecting ring, and the extrusion rod is located outside the sealing cover.
[0013] The beneficial effects of the present utility model are as follows:
[0014] (1). By providing the pipe fitting body and installing a buffer cover inside the pipe fitting body, when the water pressure inside the pipe fitting body is relatively large, an impact force will be generated on the buffer cover. Since a shock-absorbing spring is fixedly connected between the buffer cover and the pipe fitting body, the buffer cover will receive the impact force of the water pressure and at the same time buffer the inner wall of the pipe fitting body. The generated impact force continuously weakens by moving through the moving holes inside the pipe fitting body via the nylon rods. At this time, the pressure-bearing strength of the inner wall of the pipe fitting body can be improved.
[0015] (2). By providing the pipe fitting body and having a connecting ring slidably connected to the outside of the pipe fitting body, when two pipe fitting bodies are connected by threads, then by moving the connecting ring so that the connecting ring moves to the connection part of the two pipe fitting bodies, and by rotating the rotating cover, the rotating cover drives the screw rod to rotate inside the threaded pipe. At this time, the screw rod will move into the threaded pipe, and the movement of the screw rod drives the extrusion rod to move, so that the extrusion rod squeezes the sealing cover outside the reset spring, causing the sealing cover to move to the connection part of the two pipe fitting bodies, thereby performing a sealing treatment to prevent water leakage.

Specific implementation mode
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1 Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0024] A high-strength pipe fitting includes a pipe fitting body 1. A moving hole 2 is opened in the inner wall of the pipe fitting body 1. A nylon rod 3 is slidably clamped inside the moving hole 2. A buffer cover 4 is fixedly connected to the outside of the nylon rod 3. A shock-absorbing spring 5 is fixedly connected to the top of the buffer cover 4.
[0025] Specifically, as Figure 1 shown, the moving holes 2 are evenly distributed in the inner wall of the pipe fitting body 1. The buffer cover 4 is movably connected to the inside of the pipe fitting body 1 through the nylon rod 3. The buffer covers 4 are symmetrically distributed inside the pipe fitting body 1. The top of the shock-absorbing spring 5 is fixedly connected to the inner wall of the pipe fitting body 1.
[0026] In this implementation scheme: By providing the pipe fitting body 1 and installing a buffer cover 4 inside the pipe fitting body 1, when the water pressure inside the pipe fitting body 1 is relatively large, an impact force will be generated on the buffer cover 4. Since a shock-absorbing spring 5 is fixedly connected between the buffer cover 4 and the pipe fitting body 1, the buffer cover 4 will receive the impact force of the water pressure and at the same time buffer the inner wall of the pipe fitting body 1. The generated impact force is continuously weakened by the continuous frictional movement of the nylon rod 3 in the moving hole 2 inside the pipe fitting body 1. At this time, the pressure-bearing strength of the inner wall of the pipe fitting body 1 can be improved.
[0027] Embodiment 2 Please refer toFigure 1 , Figure 2 and Figure 4 , the difference between this embodiment and Embodiment 1 is that: an adapter ring 6 is slidably connected to the outer side of the pipe fitting body 1, a hidden groove 7 is formed inside the adapter ring 6, a return spring 8 is fixedly connected to the inner wall of the hidden groove 7, a sealing cover 9 is fixedly connected to the bottom of the return spring 8, a threaded pipe 10 is fixedly connected to the outer side of the adapter ring 6, a screw rod 11 is threadedly connected to the inside of the threaded pipe 10, a rotating cover 12 is fixedly connected to the top of the screw rod 11, and an extrusion rod 13 is fixedly connected to the bottom of the screw rod 11.
[0028] Specifically, as Figures 1-4 shown, the return springs 8 are symmetrically distributed between the sealing cover 9 and the inner wall of the hidden groove 7, and the sealing cover 9 is located inside the hidden groove 7. The sealing covers 9 are symmetrically distributed on the outer side of the pipe fitting body 1. The screw rod 11 is threadedly connected to the inside of the threaded pipe 10 through the rotating cover 12. The extrusion rod 13 passes through the inside of the adapter ring 6, and the extrusion rod 13 is located outside the sealing cover 9.
[0029] In this implementation scheme: by providing the pipe fitting body 1, an adapter ring 6 is slidably connected to the outer side of the pipe fitting body 1. When two pipe fitting bodies 1 are connected by threads, then by moving the adapter ring 6, the adapter ring 6 is moved to the connection part of the two pipe fitting bodies 1. By rotating the rotating cover 12, the rotating cover 12 drives the screw rod 11 to rotate inside the threaded pipe 10. At this time, the screw rod 11 will move into the threaded pipe 10. By the movement of the screw rod 11, the extrusion rod 13 is driven to move, so that the extrusion rod 13 exerts extrusion on the sealing cover 9 outside the return spring 8, causing the sealing cover 9 to move to the connection part of the two pipe fitting bodies 1, thereby performing a sealing process to prevent water leakage.
