[0002] The pipe end refers to the port part of a pipeline device that connects to equipment or another pipe section. It undertakes the key functions of media transportation and sealing. Its connection reliability directly affects the safe operation of the device. In response to the problem that traditional flange bolt connections are prone to sealing failure due to vibration and impact, the pipe end fastening clamp adopts a combination design of annular metal strip and locking mechanism. It applies uniform circumferential pressure through hydraulic or mechanical means to make the rubber gasket fit tightly against the pipe wall. It can not only be quickly disassembled and maintained, but also effectively prevent high-pressure fluid leakage, becoming an important innovative solution for modern industrial pipeline maintenance.
[0003] A search revealed Chinese Patent Publication No. CN105587935B, which discloses a pipe end fastening clamp, relating to the field of fasteners. The clamping band is rolled into a clamp body with a fitting area. The clamp body forms an overlapping portion, which includes an outer band and an inner band. The fitting area is elliptical. The manufacturing method involves first producing the clamping band, then directly rolling it into a clamp body with an elliptical fitting area. The usage method involves directly rolling the clamping band into a clamp body with a fitting area; pre-forming the fitting area to make it elliptical; fitting the clamp body onto the pipe fitting, so that the clamp body forms an abutting connection with the pipe fitting at the short axis portion corresponding to the fitting area; and further tightening the clamp using a clamping tool. The purpose of this invention is to provide a clamp that is easy to install and can be effectively pre-fixed to the pipe fitting. However, in actual use, the above-mentioned device has the problem that the clamp can move freely in the axial direction of the pipe, making it difficult to grasp its proper position on the pipe. Therefore, a pipe end fastening clamp is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a pipe end fastening clamp, which aims to improve the problem that the clamp in the prior art can move freely in the axial direction of the pipe, making it difficult to grasp its proper position on the pipe.

An outer closing component is provided on the outer wall of the outer band. A durability mechanism is provided on the outer wall of the outer band.
[0006] The above technical solution involves rotating the nut on the rear extension plate of the outer band to drive the screw rod to move longitudinally along the screw hole.

The distal end of the screw 7 is fixedly connected to a nut 6, which is used to control the longitudinal displacement of the screw 7. Several limiting blocks 4 are fixedly installed on the front side of the outer wall of the outer band 1 to limit the positive offset of the device body. The outer wall of the inner band 3 is equipped with an inner fitting component, which includes a curved band 11. The outer wall of the curved band 11 is fixed to the outer wall of the inner band 3. A groove 12 is opened on the inner wall of the inner band 3. The curved band 11 and the groove 12 achieve the positioning and locking of the inner band 3 through sliding cooperation. An outer fitting component is set on the outer wall of the outer band 1. The outer fitting component includes a locking piece 20. The right side of the locking piece 20 is fixed to the left outer wall of the inner band 3. A rectangular hole 19 is opened on the left outer wall of the outer band 1. The rectangular hole 19 and the locking piece 20 are interlocked to fix the relative position of the outer band 1. The outer wall of the outer band 1 integrates a durability mechanism 2. The durability mechanism 2 extends the overall service life of the device by enhancing the wear resistance and corrosion resistance of the material, and improves the operational stability and reliability.
[0041] Reference Figure 1 , Figure 4 and Figure 5 The durability mechanism 2 includes a fixed bracket 204, the bottom of which is fixedly connected to the top of the outer wall of the outer band 1. A pressure sensor 205 is fixedly connected to the outer wall of the fixed bracket 204, which monitors and provides feedback on the pressure status at the pipe connection in real time. This ensures that the pre-tightening force applied during the tightening process of the clamp meets the requirements, preventing leakage due to insufficient pressure or damage to components due to excessive pressure, thereby ensuring sealing performance and device safety. The fixed bracket 204 is used to fix the pressure sensor 205, ensuring its operational stability. An anti-corrosion layer 201 is fixedly connected to the inner wall of the outer band 1, which protects against corrosive media. The metal contact surface prevents electrochemical corrosion or oxidation rust, thereby maintaining the sealing performance, structural strength and long-term durability of the pipeline connection. The inner wall of the anti-corrosion layer 201 is fixedly connected to the support layer 202, which maintains the overall structural stability of the clamp by rigidly reinforcing and uniformly dispersing the external pressure or vibration load on the pipeline, preventing deformation or displacement at the pipeline connection due to uneven stress. The inner wall of the support layer 202 is fixedly connected to the wear-resistant layer 203, which protects the integrity of the clamp and pipeline surface by resisting mechanical wear caused by friction, vibration or media scouring at the pipeline connection, extending service life and ensuring the stability and reliability of the sealing structure.
[0042] Specifically, the bottom outer wall of the fixed bracket 204 is fixedly connected to the top outer wall of the outer band 1. A pressure sensor 205 is integrated into the outer wall of the fixed bracket 204. The pressure sensor 205 monitors the pressure data at the pipe connection in real time and provides dynamic feedback to ensure that the pre-tightening force during the clamping process is within a reasonable threshold, preventing seal failure due to excessively low pressure or component overload damage due to excessively high pressure, thus maintaining the sealing performance and operational safety of the device. The fixed bracket 204 provides rigid positioning support for the pressure sensor 205, ensuring its monitoring accuracy and operational stability. The inner wall of the outer band 1 is composite with an anti-corrosion layer 201. The anti-corrosion layer 201 prevents contact between corrosive agents such as moisture and chemicals and the metal substrate, inhibiting electrochemical corrosion. The corrosion process protects the integrity of the pipeline connection interface, enhances the durability of the seal and resistance to environmental erosion. The inner side of the anti-corrosion layer 201 is combined with the support layer 202. The support layer 202 uses high rigidity material to disperse the external pressure and vibration energy borne by the pipeline, evenly transmits the load distribution, avoids deformation and displacement caused by local stress concentration, and maintains the geometric stability of the overall structure of the clamp. The inner side of the support layer 202 is covered with a wear-resistant layer 203. With its high hardness and wear-resistant properties, the wear-resistant layer 203 resists the mechanical wear caused by friction, vibration and medium flow at the pipeline connection, prevents surface peeling or damage to the sealing structure, extends the service life of the clamp and the pipeline, and ensures the reliable continuation of the fastening and sealing function under complex working conditions.
[0043] Reference Figure 1 , Figure 2 and Figure 3A humidity sensor 14 is fixedly connected to the outer wall of the outer band 1. This sensor monitors changes in humidity in the environment or sealed area in real time, providing early warning of moisture intrusion risks and preventing metal corrosion, aging of sealing materials, or ice expansion caused by moisture accumulation. This ensures the reliability of pipe connections and the long-term safe operation of the device. A heating element 13 is also fixedly connected to the outer wall of the outer band 1. It works in conjunction with the humidity sensor 14; when moisture is detected, the heating element 13 is activated to remove it. A luminous indicator strip 16 is fixedly connected to the bottom of the inner wall of the inner band 3. This strip absorbs ambient light and emits light continuously in the dark, providing a quick location marker. This facilitates rapid identification of clamp positions and inspection of installation status in low light or emergency situations, ensuring smooth maintenance operations. For timeliness and safety, the surface of the luminous indicator strip 16 is rounded. A back plate 18 is fixedly connected to the outer wall of the outer band 1. A QR code identification mark 17 is fixedly connected to the outer wall of the back plate 18. It binds device information through a unique code to achieve rapid scanning and identification, improving operation and maintenance efficiency and accuracy. By providing rigid support and protection, it ensures that the QR code identification mark 17 remains flat, fixed in position and clear and readable in complex environments, which facilitates accurate scanning and long-term stable identification by the equipment. Multiple friction strips 10 are fixedly connected to the inner wall of the curved band 11. By increasing the friction coefficient of the contact surface, it effectively suppresses the circumferential rotation of the pipeline caused by vibration, pressure fluctuation and temperature change. The multiple friction strips 10 are all arranged at equal intervals.
[0044] Specifically, the outer wall of the outer strip 1 integrates a humidity sensor 14. The humidity sensor 14 continuously collects ambient humidity data from the sealed area and analyzes its changing trends to provide timely warnings of moisture infiltration risks. This prevents moisture accumulation from causing corrosion of the metal surface, degradation of the sealing material, and the icing expansion effect, ensuring the long-term stable operation of the pipeline connection structure and the overall safety of the device. The outer wall of the outer strip 1 is equipped with a heating element 13. The heating element 13 and the humidity sensor 14 form a linkage mechanism. When the humidity sensor 14 detects that the ambient humidity exceeds a threshold, it automatically triggers the heating element 13 to heat up and dehumidify, eliminating the potential damage of moisture to the sealing interface. The bottom of the inner wall of the inner strip 3 is fixedly installed with a luminous indicator strip 16. The luminous indicator strip 16 absorbs visible light to store energy and releases persistent cold light in low-light environments, forming a highly recognizable positioning mark to assist operators in navigating in the dark. In environmental or emergency situations, the clamp installation points can be quickly identified and their tightness checked to ensure the timeliness and safety of maintenance operations. The surface of the luminous indicator strip 16 is polished with rounded corners to eliminate potential hazards. The outer wall of the outer band 1 is fixedly connected to the back plate 18, and the outer wall of the back plate 18 is attached with a QR code identification mark 17. The QR code identification mark 17 is associated with information such as device model, installation parameters, and maintenance records through a unique serial code. The back plate 18 provides rigid support and physical protection for the QR code identification mark 17 to ensure efficient and accurate identification by the scanning equipment. Multiple friction strips 10 are evenly fixed on the inner wall of the curved band 11. The friction strips 10 suppress the sliding of the pipeline caused by mechanical vibration, pressure pulsation, thermal expansion and contraction by increasing the friction coefficient of the contact surface. All friction strips 10 are distributed along the axis of the curved band 11 at fixed intervals to form a uniform friction gradient.
[0045] Working principle: First, the screw 7 is driven to move longitudinally along the screw hole 15 by rotating the nut 6 on the extension plate 5 on the rear side of the outer band 1. The bottom end of the screw 7 is rigidly connected to the fastening pad 9. When the fastening pad 9 is in full contact with the pipe surface, the rotation of the nut 6 is stopped. At this time, the spring 8 at the top of the screw 7 is compressed to generate a preload force to suppress the reverse axial displacement of the hoop. The limiting block 4 set on the front side of the outer band 1 simultaneously blocks the forward axial displacement of the hoop. The two-way constraint mechanism ensures that the hoop is stably positioned along the pipe axis. The tightness of the hoop is adjusted by rotating the nut 6. The preload force of the spring 8 is used to compensate for the gap changes caused by pipe vibration or thermal expansion and contraction. The limiting block 4 and the preload force form a two-way locking effect, so that the hoop can be continuously maintained in a tight state under dynamic working conditions.
[0046] Furthermore, this clamp achieves reliable sealing and long-term protection of the pipeline connection through a multi-layer composite structure. The outer wear-resistant layer 203 is made of high-strength material, directly contacting the medium flow and effectively resisting fluid erosion and mechanical wear. The middle support layer 202 has rigid pressure-bearing characteristics, ensuring the overall structural stability of the clamp. The outer anti-corrosion layer 201 isolates environmental corrosion factors and improves weather resistance. The external pressure sensor 205 monitors the stress state of the clamp's outer wall in real time, dynamically assessing the fastening status and sealing performance through feedback pressure changes, providing early warning for device operation. The three-layer collaborative structure achieves multiple protections while ensuring mechanical strength, significantly extending service life. The pressure sensing device enables visual monitoring of the operating status. The overall design takes into account wear resistance, pressure resistance, and corrosion resistance, adapting to complex working environments and ensuring safe and reliable pipeline connections.
