Description

Technical Field

[0001] This utility model relates to the field of threaded joint technology, specifically to a jacketed full threaded joint. Background Technology

[0002] Threaded pipe fittings are broadly classified into composite and integral types. In the composite type, one of the two pipes being connected is a steel pipe, and the other is a fitting. In this case, external threads are formed on the outer circumference of both ends of the steel pipe, and internal threads are formed on the inner circumference of both ends of the fitting. The external thread of the steel pipe is screwed into the internal thread of the fitting, thereby securing the connection. In the integral type, both pipes being connected are steel pipes, and no additional fitting is used. In this case, external threads are formed on the outer circumference of one end of the steel pipe, and internal threads are formed on the inner circumference of the other end. The external thread of one steel pipe is screwed into the internal thread of the other steel pipe, thereby securing the connection.

[0003] Traditional pipe joints mostly use rigid threaded connection structures, which have insufficient self-adaptive clamping ability and are difficult to adapt to deformation caused by thermal expansion and contraction or vibration of the pipe, leading to sealing failure.

[0004] Therefore, it is necessary to invent a jacketed fully threaded joint to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a jacketed fully threaded connector that, through the cooperation of an inner connecting tube and an adaptive clamping mechanism, can more effectively clamp the pipe, thus solving the problem of difficulty in adaptively clamping pipes in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a jacketed fully threaded connector, comprising an inner connecting tube, a connector jacket fixedly connected to the outer wall of the inner connecting tube, an adaptive clamping mechanism provided inside the connector jacket, the adaptive clamping mechanism comprising two sets of anti-loosening screws threaded to the surface of the inner connecting tube, the threaded connection portion of the anti-loosening screws being coated with an insulating layer, two sets of clamping cavities formed on the inner wall of the inner connecting tube, the anti-loosening screws penetrating the interior of the inner connecting tube and extending into the interior of the clamping cavity, the inner sidewall of the clamping cavity being... A spring frame is provided on the side, which abuts against the anti-loosening screw. The spring frame is slidably connected to the inner wall of the inner connecting pipe. A disc spring is snapped into the inner wall of the spring frame. Several sets of polyurethane colloids are fixedly connected to the inner wall of the spring frame. The surface of the polyurethane colloids that contacts the disc springs has abutment grooves. Several sets of fiber meshes are wrapped inside the polyurethane colloids. Through the cooperation of the inner connecting pipe and the self-adaptive clamping mechanism, the interaction between the pipe, the polyurethane colloids, and the disc springs allows the polyurethane colloids to clamp the pipe and absorb impact under the action of the disc springs to protect the pipe.

[0007] Preferably, an inner connecting pipe two is fixedly connected to the right side of the connector clamp, and the positions of the inner connecting pipe one and the inner connecting pipe two correspond to each other. The pipe passes through the inner connecting pipe two and the external thread.

[0008] Preferably, an outer connecting pipe is provided on the left side of the connector sleeve, and a fastening nut is provided on the outer side of the outer connecting pipe and the inner connecting pipe, so as to realize the connection between the outer connecting pipe and the external thread by fastening the nut.

[0009] Preferably, the outer diameter of the end of the outer connecting pipe and the inner connecting pipe away from the fastening nut is larger than the outer diameter of the end closer to the fastening nut. The maximum outer diameter of the outer connecting pipe and the inner connecting pipe is consistent with the inner diameter of the fastening nut. By changing the outer diameter, the connection part between the outer connecting pipe and the external thread is made into a conical surface, thereby further improving the connection effect.

[0010] Preferably, the outer connecting pipe and the outer side wall of the inner connecting pipe are fixedly connected with several sets of internal threads, and the inner side wall of the fastening nut is fixedly connected with several sets of external threads. The internal threads and external threads are spaced apart and are threadedly connected. The fastening nut achieves the connection between the outer connecting pipe and the external threads through the cooperation of the internal threads and the external threads.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] By cooperating with the internal connecting tube and the adaptive clamping mechanism, a gradient modulus structure is formed by the combination of polyurethane colloid and embedded fiber mesh. The contact groove on the surface of the polyurethane colloid allows the disc spring to cooperate with the polyurethane colloid to achieve elastic deformation clamping and absorb the energy generated by vibration, thereby realizing dynamic clamping of the pipe. At the same time, the disc spring and polyurethane colloid absorb low-frequency and high-frequency impacts respectively, thereby improving the practicality of the structure. Through the cooperation of internal and external threads and other parts, and matching the inner diameter of the fastening nut, a self-tightening conical surface connection is formed, which increases the sealing and fastening performance.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides, for example Figure 1-4The diagram shows a jacketed fully threaded connector, comprising an inner connecting tube 1. A connector jacket 101 is fixedly connected to the outer wall of the inner connecting tube 1. An adaptive clamping mechanism 2 is provided inside the connector jacket 101. The adaptive clamping mechanism 2 includes two sets of anti-loosening screws 201 threadedly connected to the surface of the inner connecting tube 1, with the threaded portion of the anti-loosening screws 201 coated with an insulating layer. Two sets of clamping cavities 202 are formed on the inner wall of the inner connecting tube 1. The anti-loosening screws 201 penetrate the interior of the inner connecting tube 1 and extend into the interior of the clamping cavities 202. A spring frame 203 is provided inside the clamping cavity 202, abutting against the anti-loosening screws 201. The spring frame 203 is slidably connected to the inner wall of the inner connecting tube 1. A disc spring 207 is engaged with the inner wall of the spring frame 203. Several [unclear - possibly referring to other components] are fixedly connected to the inner wall of the spring frame 203. A polyurethane colloid 204 is provided, and the surface of the polyurethane colloid 204 in contact with the disc spring 207 has an abutment groove 205. The interior of the polyurethane colloid 204 is wrapped with several sets of fiber mesh 206. Through the cooperation of the inner connecting tube 1 and the adaptive clamping mechanism 2, the interaction between the pipe, the polyurethane colloid 204, and the disc spring 207 is utilized to clamp the pipe and absorb impact under the action of the disc spring 207 to protect the pipe. The right side of the connector sleeve 101 is fixedly connected to the inner connecting tube 2 5. The positions of the inner connecting tube 1 and the inner connecting tube 2 5 are corresponding. The pipe passes through the inner connecting tube 2 5 and the external thread 6. The left side of the connector sleeve 101 is provided with the outer connecting tube 4. The outer connecting tube 4 and the outer side of the inner connecting tube 1 1 are provided with a fastening nut 3. The outer connecting tube 4 and the external thread 6 are connected through the fastening nut 3.

[0022] Refer to the instruction manual appendix Figure 1-4The outer diameter of the end of the outer connecting pipe 4 and the inner connecting pipe 1 furthest from the fastening nut 3 is larger than the outer diameter of the end closest to the fastening nut 3. The maximum outer diameter of the outer connecting pipe 4 and the inner connecting pipe 1 is the same as the inner diameter of the fastening nut 3. By changing the outer diameter, the connection part between the outer connecting pipe 4 and the external thread 6 is made into a conical surface, thereby further improving the connection effect. Several sets of internal threads 7 are fixedly connected to the outer sidewall of the outer connecting pipe 4 and the inner connecting pipe 1, and several sets of external threads 6 are fixedly connected to the inner sidewall of the fastening nut 3. The internal threads 7 and the external threads 6 are spaced apart and are threadedly connected. The cooperation between the internal threads 7 and the external threads 6 enables the fastening nut 3 to connect the outer connecting pipe 4 and the external thread 6. The connection is achieved through the cooperation of the inner connecting pipe 1 and the adaptive clamping mechanism 2. The polyurethane colloid 204 and the embedded fiber mesh 206 cooperate to form a gradient modulus structure. The anti-contact groove 205 is opened on the surface of the polyurethane colloid 204 so that the disc spring 207 cooperates with the polyurethane colloid 204 to achieve elastic deformation clamping and absorb the energy generated by vibration, thereby realizing dynamic clamping of the pipe. At the same time, the disc spring 207 and the polyurethane colloid 204 absorb low-frequency and high-frequency impacts respectively, thereby improving the practicality of the structure. Through the cooperation of parts such as the internal thread 7 and the external thread 6, and matching the inner diameter of the fastening nut 3, a self-tightening conical surface connection is formed, which increases the sealing and fastening performance.

[0023] The working principle of this practical application is as follows:

[0024] Refer to the instruction manual appendix Figure 1-4 When pipe installation is required, the pipe is first passed through the inner connecting pipe 1, clamping cavity 202 and inner connecting pipe 5 in sequence. The outer connecting pipe 4 is positioned by the engagement of the external thread 6 and the internal thread 7. Then, tighten the fastening nut 3 so that the conical structure forces the outer connecting pipe 4 to contract radially, and rotate the anti-loosening screw 201 to push the spring frame 203. The threaded connection of the anti-loosening screw 201 is coated with an insulating layer to extend its service life. The disc spring 207 is compressed to the preset stroke. After the pipe passes through the inner connecting pipe 1, the polyurethane colloid 204 is compressed to extend to both sides and clamped under the restriction of the disc spring 207, thereby achieving self-adaptive clamping. When the pipe is impacted, the spring frame 203 slides and changes the curvature of the contact groove 205 of the polyurethane colloid 204, thereby cooperating with the fiber mesh 206 to replace the wear of the polyurethane colloid 204. Finally, the wear is converted into heat energy consumption through spring damping and internal friction of the colloid.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
