[0002] In the field of pipe connection, pipe connection assemblies are indispensable components, which are responsible for tightly connecting various pipe sections, valves, joints and other components together to ensure smooth and safe fluid transmission.

[0003] Traditional pipe connection methods include threaded connection, flange connection or clamp connection, etc. Although they can meet the needs of fluid transmission to some extent, when encountering vibration, pressure changes and other external factors, traditional pipe connection methods often have difficulty in maintaining long-term stable connection, and the connection is prone to looseness. TECHNICAL CONTENT

[0004] The present application discloses a pipe connection assembly, a fluid transmission device and a liquid cooling system, which are used to solve the problem of joint connection looseness.

The joint fixing member is sleeved outside the first joint, the joint fixing member is provided with a first through hole, and the clamping member penetrates through the first through hole and abuts against the first joint. In the embodiment of the present application, since the clamping member abuts against the surface of the first joint through the first through hole in the joint fixing member, the clamping member applies additional pressure to the first joint through the joint fixing member, further consolidates the connection between the first joint and the pipe, prevents the connection from loosening or leaking due to the abutting of the first joint and the second joint, or due to factors such as vibration and pressure change, and enhances the connection stability between the first joint and the pipe, and between the first joint and the second joint.

[0006] In a possible implementation, the first through hole is arranged on the side wall of the joint fixing member.

After the clamping member is arranged in the first through hole, the first joint can be prevented from moving in the first direction and the second direction, and the connection stability of the first joint can be improved. In addition, arranging the first through hole on the side wall of the joint fixing member facilitates the machining of the first through hole and facilitates the vertical installation of the clamping member from top to bottom, which can improve the assembly efficiency of the clamping member.

[0007] In a possible implementation, the outer surface of the first joint is provided with a fixing hole corresponding to the first through hole position, and the fastening member penetrates through the first through hole and is embedded in the fixing hole. In the embodiment of the present application, since the fastening member penetrates through the first through hole and is embedded in the fixing hole of the first joint, the fastening member not only fastens the first joint but also limits the first joint when the fastening member is fastened, thereby enhancing the stress strength of the first joint.

[0008] In a possible implementation, the outer contour of the first joint matches the inner contour of the joint fixing member, so that the joint fixing member limits the first joint in a preset direction. In the embodiment of the present application, since the outer contour of the first joint matches the inner contour of the joint fixing member, the first joint plays a guiding role when the joint fixing member is installed, thereby facilitating the installation of the joint fixing member. In addition, after the joint fixing member is fixed, the anti-torsion capability of the first joint is improved in turn, thereby preventing the connection from being loosened or leaked due to the torsion of the first joint caused by external force.

[0009] In a possible implementation, the first joint comprises a first connecting part and a second connecting part, the first connecting part and the second connecting part are detachably connected, the first connecting part is connected with the pipeline, the second connecting part is connected with the second joint, and the fastening member abuts against the second connecting part. In the embodiment of the present application, the first joint is designed as a detachable connection structure, when any part fails or needs to be maintained, the first joint can be conveniently disassembled and replaced without replacing the whole joint, thereby reducing the maintenance cost and prolonging the overall service life of the joint. Meanwhile, the design that the fastening member abuts against the second connecting part enhances the connection stability between the second connecting part and the adjacent component. Through the fastening effect of the fastening member, the second connecting part is firmly fixed in place, thereby effectively preventing the connection from being loosened or displaced due to vibration, external force impact or pressure change, and thereby ensuring the stability and reliability of the whole pipeline connection assembly.

[0010] In a possible implementation, the pipeline connection assembly further comprises a pipeline mounting member and a positioning pin, the positioning pin is arranged between the joint fixing member and the pipeline mounting member, and the positioning pin is used for aligning the joint fixing member and the pipeline mounting member. In the embodiment of the present application, since the pipeline mounting member and the joint fixing member are connected by the positioning pin, the accurate positioning of the joint fixing member can be ensured, thereby facilitating the installation of the joint fixing member. Meanwhile, since the positioning pin is arranged, the torsion resistance of the joint fixing member is enhanced, thereby enhancing the stability of the pipeline and the joint.

[0011] In a possible implementation, the positioning pin is integrally formed with the pipeline mounting member, the joint fixing member is provided with a first positioning hole corresponding to the positioning pin, and the positioning pin is inserted into the first positioning hole. In the embodiment of the present application, since this mode does not need to arrange an additional positioning pin, the structure is compact, the number of parts is reduced, and the installation process is simplified.

[0012] Or, the positioning pin is integrally formed with the joint fixing part, the pipeline mounting part is provided with a second positioning hole corresponding to the positioning pin, and the positioning pin is inserted into the second positioning hole. In the embodiment of the application, since this way also does not need to set an additional positioning pin, the structure is compact, the number of parts is reduced, and the installation process is simplified. At the same time, this way can make the structure of the joint fixing part more stable, and the positioning pin is not easy to lose;

[0013] Or, the positioning pin is a separate structural part, the joint fixing part is provided with a first positioning hole, the pipeline mounting part is provided with a second positioning hole, one end of the positioning pin is inserted into the first positioning hole, and the other end of the positioning pin is inserted into the second positioning hole. In the embodiment of the application, since the positioning pin is a separate structural part, it is convenient to replace and maintain, and has higher flexibility, and can be customized according to different pipeline mounting parts and joint fixing parts.

[0014] In a possible implementation, the pipeline connection assembly includes a plurality of positioning pins, and the plurality of positioning pins are arranged on both sides of the pipeline. In the embodiment of the application, since there are a plurality of positioning pins and they are arranged on both sides of the pipeline, it is not necessary to hold the joint fixing part by hand during the tightening process of the fastening part, which facilitates installation operation, and at the same time, the torsional force that can be borne by the joint fixing part is doubled, thereby improving the connection stability of the pipeline and the joint.

[0015] In a possible implementation, the pipeline connection assembly further includes a pipeline fixing part, and the pipeline fixing part is located between the pipeline mounting part and the joint fixing part. The joint fixing part is fixed to the pipeline mounting part through the pipeline fixing part. In the embodiment of the application, since the joint fixing part is fixed to the pipeline mounting part through the pipeline fixing part, the pipeline fixing part is made of high-strength material, which can strengthen the fixing strength, facilitate repeated disassembly of the joint fixing part, and thereby improve the convenience of assembly.

[0016] In a possible implementation, the pipeline fixing part is provided with a second through hole for the positioning pin to pass through. The joint fixing part, the pipeline fixing part and the pipeline mounting part are precisely aligned through the cooperation of the positioning pin and the second through hole. In the embodiment of the application, since the positioning pin connects the joint fixing part, the pipeline fixing part and the pipeline mounting part together, the joint fixing part, the pipeline fixing part and the pipeline mounting part are positioned in the first direction and the second direction, so that the precise alignment between the joint fixing part, the pipeline fixing part and the pipeline mounting part can be realized, and the stability and connection precision of the entire pipeline connection assembly are ensured.

[0017] In a possible implementation, the second through hole is a stepped hole, and the positioning pin is provided with a step corresponding to the stepped hole. In the embodiment of the present application, the second through hole is designed as a stepped hole, which means that the inner wall of the hole has different diameter sections, forming a stepped structure, and the positioning pin is provided with a step corresponding to the stepped hole. When the positioning pin is inserted into the second through hole, the step and the different diameter sections of the stepped hole can form a close fit. This fit not only increases the contact area, but also provides more frictional resistance, thereby effectively preventing the positioning pin from loosening or slipping in the second through hole and improving the stability of the overall connection.

[0018] In a possible implementation, the pipe mounting member or the joint fixing member is provided with a mounting position, and the pipe fixing member is mounted on the mounting position. In the embodiment of the present application, since the pipe mounting member is provided with a mounting position for limiting the pipe fixing member, the pipe fixing member can be fixedly connected to the pipe mounting member by the first fixing member, thereby improving the connection strength of the pipe fixing member.

[0019] In a possible implementation, the mounting position is a groove. In the embodiment of the present application, since the mounting position of the pipe mounting member is in the form of a groove, the pipe fixing member will not protrude excessively from the pipe mounting member after installation, thereby facilitating the installation of the pipe fixing member between the joint fixing member and the pipe mounting member and ensuring the stability and accuracy of the installation.

[0021] Or / and, the pipe connection assembly comprises at least one third fixing member, and the joint fixing member and the pipe fixing member are fixedly connected to the pipe mounting member by the third fixing member. In the embodiment of the present application, since the pipe fixing member is fixed to the pipe mounting member by the third fixing member, and the joint fixing member and the pipe fixing member are fixedly connected by the third fixing member, only one fixing member is needed to achieve the connection and fixation of the three structural members, thereby simplifying the installation process, reducing the number of required fixing members, reducing the installation difficulty and cost, and improving the assembly efficiency.

[0022] In a possible implementation, if the pipe fixing member is fixedly connected with the pipe mounting member through the first fixing member, and the joint fixing member is fixedly connected with the pipe fixing member through the second fixing member, the first fixing member and the second fixing member are arranged at different positions on the preset projection surface.

[0044] As shown in Figure 2 The pipe connection assembly 1 provided by the embodiment of the present application includes a first connector 10, a connector fixing member 20 and a fastening member 30. The first connector 10 is fixed by the connector fixing member 20 combined with the fastening member 30, which reduces the possibility of loose connection of the first connector 10 and improves the connection stability of the first connector 10. The following is a detailed description of the specific embodiments of the present application.

[0045] Embodiment one

[0046] As shown in Figures 1 to 5 The pipe connection assembly 1 provided by the embodiment of the present application includes a first connector 10, a connector fixing member 20 and a fastening member 30. The first connector 10 is fixed by the connector fixing member 20 combined with the fastening member 30, which reduces the possibility of loose connection of the first connector 10 and improves the connection stability of the first connector 10. The following is a detailed description of the specific embodiments of the present application.

[0047] The first joint 10 is a connecting piece connecting the pipeline 50 and the second joint 40, mainly used to ensure smooth transmission of fluid and connection. Specifically, the first joint 10 is a cylinder with two open ends, one end of the first joint 10 is connected to the pipeline 50, and the other end is connected to the second joint 40 (the second joint 40 is a joint of an external device or a joint of other devices in the system). The first joint 10 includes but is not limited to a straight joint, a three-way joint, an elbow, a joint with a live nut, a hinged joint, a transition joint, etc. According to the specific application scenario and requirements, the first joint 10 can be made of different materials, such as stainless steel, carbon steel, plastic, etc. In addition, the connection between the first joint 10 and the pipeline 50 or the second joint 40 can be threaded connection, clamping, etc.

[0048] The joint fixing piece 20 is used to fix the first joint 10 so that the first joint 10 does not move in a specific direction. The shape of the joint fixing piece 20 can be set according to the shape of the first joint 10. The material of the joint fixing piece 20 can be the same as or stronger than that of the first joint 10. When the material of the joint fixing piece 20 is the same as that of the first joint 10, the compatibility and matching between the two can be ensured. It can be understood that if the first joint 10 is made of metal, selecting a joint fixing piece 20 made of the same metal can ensure that they have similar performance under environmental conditions such as corrosion and temperature change. If the joint fixing piece 20 has higher strength than the first joint 10, it can better withstand the pressure and vibration generated during fluid transmission.

[0049] It can be understood that the joint fixing piece 20 is sleeved outside the first joint 10, which means that the first joint 10 is wrapped inside the joint fixing piece 20. The first joint 10 can be completely wrapped in the joint fixing piece 20, or partially wrapped in the joint fixing piece 20. When the first joint 10 is partially wrapped in the joint fixing piece 20, the end of the first joint 10 close to the second joint 40 will protrude out of the joint fixing piece 20. Such a design is convenient for operation and can ensure that the first joint 10 and the second joint 40 are quickly and firmly connected.

[0050] In order to facilitate the joint fixing piece 20 to be sleeved outside the first joint 10 or removed from the outside of the first joint 10, a gap is provided between the joint fixing piece 20 and the first joint 10. The gap can make the joint fixing piece 20 generate less resistance during installation and removal. Because there is a gap between the joint fixing piece 20 and the first joint 10, during the connection of the first joint 10 and the second joint 40, or due to factors such as vibration and pressure change, the first joint 10 can move in the first direction and / or the second direction, wherein the first direction is the central axis direction of the first joint 10, and the second direction is perpendicular to the central axis direction of the first joint 10.

[0051] In order to prevent the first joint 10 from moving in the first direction and the second direction, the joint fixing member 20 and the first joint 10 are fixedly connected by arranging the fastener 30 between the joint fixing member 20 and the first joint 10. Since the joint fixing member 20 is firmly installed on the fluid transmission device 2 and remains stationary, the first joint 10 is effectively fixed by fastening the fastener 30 with the joint fixing member 20 and the first joint 10 respectively. In this way, even if vibration or pressure changes occur when the second joint 40 is connected to the first joint 10, the first joint 10 can be prevented from moving in the first direction and / or the second direction, thereby avoiding the problems of loose connection between the first joint 10 and the pipe 50 and difficulty in fixing the first joint 10 and the second joint 40.

[0052] In order to facilitate the installation and fixation of the fastener 30, a first through hole 201 is arranged on the joint fixing member 20 to cooperate with the fastener 30. The fastener 30 passes through the first through hole 201 and abuts against the first joint 10. When the fastener 30 passes through the first through hole 201, the end thereof abuts against the surface of the first joint 10 or the corresponding recess. This abutting action enables the fastener 30 to tightly fix the first joint 10 and the joint fixing member 20 together, thereby forming a stable fixed connection structure and preventing the first joint 10 from moving in the first direction and / or the second direction. At this time, the first through hole 201 provides a through channel for the fastener 30 to reach and abut against the first joint 10, thereby achieving the purpose of fixedly connecting the first joint 10.

[0053] Specifically, the fastener 30 is threadedly connected with the joint fixing member 20. For example, the fastener 30 is a bolt or a screw, which has external threads, while the joint fixing member 20 is provided with an internal threaded hole matching the external threads. By screwing the fastener 30 into the internal threaded hole of the joint fixing member 20, the fixed connection between the fastener 30 and the joint fixing member 20 can be achieved. This connection mode effectively ensures the stability and safety of the joint fixing member 20 on the fluid transmission device 2, and facilitates disassembly and replacement, thereby providing convenience for equipment maintenance and repair.

[0054] Alternatively, the end of the fastener 30 can have the same profile as the abutting position of the first joint 10, so that the fastener 30 can firmly abut against the first joint 10. Since the profile of the end of the fastener 30 is the same as that of the abutting position of the first joint 10, the contact area between them is maximized, and the gap caused by shape mismatch is reduced. This close fit not only improves the stability of the connection, but also prevents loosening caused by vibration or external force. For example, if the first joint 10 is circular, the shape of the end of the fastener 30 is arc-shaped.

[0055] Optionally, the end of the fastening member 30 can also be provided with an anti-skid part. Specifically, the end of the fastening member 30 is provided with an anti-skid part, which is usually designed with a rough surface or special texture. Such design can increase the roughness of the contact surface when abutting against the first connector 10. According to the principle of friction in physics, the rougher the contact surface, the greater the friction. Therefore, after the anti-skid part abuts against the first connector 10, a greater friction can be generated, which can offset the sliding tendency of the first connector 10 caused by external factors (such as vibration, external force impact, etc.), thereby ensuring that the first connector 10 is firmly fixed on the connector fixing member 20 and will not slide or shift due to external factors. Specifically, the anti-skid part can be provided at the end of the fastening member 30; or the anti-skid part can be provided at the position of the first connector 10 corresponding to the abutment of the fastening member 30.

[0056] Optionally, the shape of the first through hole 201 can be circular, oval, square, track-shaped or other shapes, depending on the shape of the fastening member 30. For example, the first through hole 201 can be a stepped hole, and the fastening member 30 is a countersunk screw. By providing a countersunk screw, it can avoid being protrudingly arranged on the connector fixing member 20, and can avoid the fastening member 30 being touched by external factors, thereby preventing the fastening member 30 from loosening. Specifically, the stepped hole includes a first stepped part and a second stepped part. The first stepped part is used to accommodate the head of the countersunk screw, and the second stepped part is used to fixedly connect the countersunk screw to the connector fixing member 20. The first through hole 201 can be arranged on the side wall and the bottom wall of the connector fixing member 20. The position of the first through hole 201 is arranged so as to enable the fastening member 30 to abut against the first connector 10. The minimum inner diameter of the first through hole 201 is greater than the maximum outer diameter of the fastening member 30, so that the fastening member 30 can penetrate through the first through hole 201.

[0057] In the installation process, first, the first connector 10 is connected with the pipeline 50; then the connector fixing member 20 is sleeved on the outside of the first connector 10, and it is ensured that the connector fixing member 20 and the fluid transmission device 2 are fixedly connected together; then the fastening member 30 is inserted into the first through hole 201 and continues to penetrate through the first through hole 201 until it is fixedly connected with the connector fixing member 20; then the position of the fastening member 30 is adjusted so that the end thereof abuts against the surface of the first connector 10; finally, the second connector 40 is butted against the first connector 10.

[0058] In the embodiment of the present application, since the fastening member 30 abuts against the surface of the first connector 10 through the through hole on the connector fixing member 20, the fastening member 30 exerts additional pressure on the first connector 10 through the connector fixing member 20, further consolidates the connection between the first connector 10 and the pipeline 50, prevents loosening or leakage due to the butt joint of the first connector 10 and the second connector 40 or due to factors such as vibration and pressure change, and enhances the connection stability between the first connector 10 and the pipeline 50 and between the first connector 10 and the second connector 40.

[0059] Further, as shown in Figure 2 the first through hole 201 is arranged on the side wall of the joint fixing member 20.

[0060] Since the joint fixing member 20 is arranged outside the first joint 10, and the first through hole 201 is arranged in the joint fixing member 20, if the first through hole 201 is arranged on the bottom wall of the joint fixing member 20, when the fastening member 30 is arranged in the first through hole 201 and abuts against the first joint 10, it is impossible to prevent the relative movement of the first joint 10 in the first direction, therefore, the first through hole 201 is arranged on the side wall of the joint fixing member 20, after the fastening member 30 is arranged in the first through hole 201, it can prevent the first joint 10 from moving in the first direction and the second direction at the same time. In addition, since the first through hole 201 is arranged on the side wall of the joint fastening member 30, the operator can more conveniently check the connection state of the fastening member 30, and it is also convenient to carry out necessary maintenance operations, such as replacing the fastening member 30, adjusting the connection tightness, etc.

[0061] Optionally, the first through hole 201 is arranged on the side wall of the joint fixing member 20 and close to one end of the second joint 40. Since the first through hole 201 is close to the second joint 40, after the fastening member 30 passes through the first through hole 201, it can more directly act on the connection between the first joint 10 and the second joint 40, this design makes the fixing force of the fastening member 30 more concentrated and effective, thereby enhancing the stability of the first joint 10, preventing the first joint 10 from being displaced during the docking process of the second joint 40 with the first joint 10.

[0062] Optionally, the first through hole 201 is arranged on the side wall of the joint fixing member 20 and close to one end of the pipeline 50. Since the first through hole 201 is close to the pipeline 50, after the fastening member 30 passes through the first through hole 201, it can more directly act on the connection between the first joint 10 and the pipeline 50, this design makes the fixing force of the fastening member 30 more concentrated and effective, thereby enhancing the stability of the first joint 10, preventing the relative displacement between the pipeline 50 and the first joint 10 during the docking process of the second joint 40 with the first joint 10.

[0063] Specifically, the first through hole 201 is arranged on the upper side wall of the joint fixing member 20, so that the fastening member 30 can be vertically installed from top to bottom, which is convenient for operation.

[0064] In the embodiment of the present application, the first through hole 201 is arranged on the side wall of the joint fixing member 20. After the fastening member 30 is arranged in the first through hole 201, the first joint 10 can be prevented from moving in the first direction and the second direction, and the connection stability of the first joint 10 can be improved. In addition, the first through hole 201 is arranged on the side wall of the joint fastening member 30. This facilitates the processing of the first through hole 201 and facilitates the vertical installation of the fastening member 30 from top to bottom, and the assembly efficiency of the fastening member 30 can be improved.

[0065] Further, as shown in Figure 2 the outer surface of the first joint 10 is provided with a fixing hole 103 corresponding to the position of the first through hole 201, and the fastening member 30 penetrates the first through hole 201 and is embedded in the fixing hole 103.

[0066] It can be understood that the outer surface of the first joint 10 is provided with a fixing hole 103, the position of the fixing hole 103 corresponds to the position of the first through hole 201, that is, the fixing hole 103 is arranged at the position of the first joint 10 abutting against the fastening member 30 after the fastening member 30 penetrates the first through hole 201, and the hole diameter of the fixing hole 103 is slightly larger than the diameter of the part of the fastening member 30 penetrating the fixing hole 103. For example, the inner wall of the fixing hole 103 can be provided with threads, and the fastening member 30 is a screw. After the fastening member 30 is inserted into the fixing hole 103, the fastening member 30 is fixed in the fixing hole 103 by threads.

[0067] Optionally, the depth of the fixing hole 103 is less than the wall thickness of the first joint 10. When the fastening member 30 is embedded in the fixing hole 103, the side of the fastening member 30 is tightly fitted with the side wall of the fixing hole 103, and the bottom of the fastening member 30 is tightly fitted with the bottom wall of the fixing hole 103. Due to the tight fit between the fastening member 30 and the fixing hole 103, the uniform distribution of stress is ensured. When external load is borne, this design can avoid stress concentration phenomenon and reduce fatigue damage at the connection, thereby prolonging the service life of the fastening member 30.

[0068] Optionally, the fixing hole 103 is further provided with a first clamping part, and the fastening member 30 is provided with a second clamping part. When the fastening member 30 abuts against the fixing hole 103, the first clamping part and the second clamping part are clamped. When the fastening member 30 is installed, when the fastening member 30 is further inserted into the fixing hole 103 and reaches a predetermined position, the first clamping part and the second clamping part come into contact and gradually enter the clamping state. The tight fit between the first clamping part and the second clamping part increases the contact area and the friction force, so that the fastening member 30 can bear greater load without loosening, plays a good limiting role, and enhances the stress strength of the first joint 10.

[0069] Since the fastening member 30 is embedded into the fixing hole 103 of the first connector 10 after penetrating through the first through hole 201, the fastening member 30 plays a role of limiting the first connector 10 while fastening the first connector 10, thus enhancing the stress strength of the first connector 10.

[0070] In some embodiments of the present application, the outer profile of the first connector 10 matches the inner profile of the connector fixing member 20, so that the connector fixing member 20 limits the first connector 10 in a preset direction.

[0071] It can be understood that the preset direction is a clockwise direction or an anticlockwise direction. The meaning that the outer profile of the first connector 10 matches the inner profile of the connector fixing member 20 is that the shape of the outer profile of the first connector 10 is almost the same as the shape of the inner profile of the connector fixing member 20 to limit the first connector 10, so that the first connector 10 is not twisted by external force to cause the connection to be loose. In practice, since the connector fixing member 20 needs to be installed or disassembled, the shape of the inner profile of the connector fixing member 20 is slightly larger than the shape of the outer profile of the first connector 10. Those skilled in the art can design and realize the size of the inner and outer profiles in combination with the requirements of installation / disassembly, the requirements of limiting, and the processing technology, so as to facilitate the installation and disassembly while meeting the requirements of limiting. The present application matches the shapes of the outer profile of the first connector 10 and the inner profile of the connector fixing member 20, so that the position of the first connector 10 in the connector fixing member 20 is strictly limited and cannot be moved or deviated from the preset direction at will. Thus, when the first connector 10 is combined with the connector fixing member 20, the connector fixing member 20 can effectively limit the first connector 10 in the preset direction.

[0072] Optionally, part of the outer profile of the first connector 10 can match the inner profile of the connector fixing member 20, or the entire outer profile of the first connector 10 matches the inner profile of the connector fixing member 20. Specifically, if the first connector 10 includes a first connecting portion 101 and a second connecting portion 102, and the fastening portion of the first connector 10 is arranged on the second connecting portion 102, at this time, the profile of the second connecting portion 102 matches the connector fixing member 20, so that the first connecting portion 101 is not restricted by the connector fixing member 20, facilitating the installation and disassembly, reducing the wear and tear, and prolonging the service life.

[0073] Since the outer profile of the first connector 10 matches the inner profile of the connector fixing member 20, the first connector 10 plays a role of guiding when the connector fixing member 20 is installed, facilitating the installation of the connector fixing member 20. In addition, after the connector fixing member 20 is fixed, it in turn enhances the anti-twisting ability of the first connector 10, preventing the connection from being loose or leaking due to the first connector 10 being twisted by external force.

[0074] Further, as shown in FIG. 1, the first connector 10 includes a first connecting portion 101 and a second connecting portion 102. The first connecting portion 101 is arranged on the second connecting portion 102. The first connecting portion 101 is connected to the second connecting portion 102 through a fastening member 30. Figure 2 ,Figure 3 and Figure 4 As shown in the figure, the first joint 10 comprises a first connecting part 101 and a second connecting part 102, the first connecting part 101 and the second connecting part 102 are detachably connected, the first connecting part 101 is connected with the pipeline 50, the second connecting part 102 is connected with the second joint 40, and the fastening member 30 abuts against the second connecting part 102.

[0075] The first joint 10 is composed of the first connecting part 101 and the second connecting part 102, and the first connecting part 101 and the second connecting part 102 are detachably connected. After the first connecting part 101 and the second connecting part 102 are assembled together, the two connecting parts can be easily detached, and no damage to any part will be caused during the whole detaching process; and then, the first connecting part 101 and the second connecting part 102 can be reassembled together to restore the original connecting function and stability. For example, the first connecting part 101 and the second connecting part 102 can be connected by threads, and by setting threads on the first connecting part 101 and the second connecting part 102, they can be tightly connected together by rotating, and this connecting mode is simple in structure, easy to detach and reassemble.

[0076] The first connecting part 101 is close to the pipeline 50, and the first connecting part 101 is connected with the pipeline 50. Optionally, the first connecting part 101 and the pipeline 50 can be connected by plug-in, clamping, thread and other modes. For example, the first connecting part 101 and the pipeline 50 are connected by plug-in mode, the first connecting part 101 is provided with a deformation part, and the outer diameter of the pipeline 50 is greater than the inner diameter of the deformation part. After the pipeline 50 is inserted into the first connecting part 101, the deformation part is tightly attached to the outside of the pipeline 50, so as to realize the sealed connection of the pipeline 50 and the first connecting part 101.

[0077] The second connecting part 102 is close to the second joint 40 and connected with the second joint 40. Optionally, the second connecting part 102 and the second joint 40 can also be connected by plug-in, clamping, thread and other modes. For example, the second connecting part 102 and the second joint 40 are connected by thread mode, the second connecting part 102 is provided with external threads or internal threads, and the second joint 40 is provided with internal threads and external threads. By matching the external threads with the internal threads, the sealed connection of the second connecting part 102 and the second joint 40 is realized.

[0078] Optionally, the gap between the inner side wall of the joint fixing member 20 and the first connecting part 101 is larger than the gap between the inner side wall of the joint fixing member 20 and the second connecting part 102. When the joint fixing member 20 is sleeved on the first joint 10, since the gap between the joint fixing member 20 and the first connecting part 101 is larger, more operation space and fault tolerance are provided, and the installer or automatic equipment does not need to make excessive adjustment or fine positioning to sleeve the joint fixing member 20 on the first joint 10, thereby shortening the installation time.

[0079] In the installation process, the first connecting part 101 is first sleeved on the pipeline 50, then the second connecting part 102 is sleeved on the pipeline 50 until the second connecting part 102 abuts against the port of the pipeline 50, then the second connecting part 102 is screwed using a tool, the first connecting part 101 is simultaneously screwed under the driving action of the second connecting part 102, the pipeline 50 is tightly attached to the second connecting part 102, and finally the fastening member 30 abuts against the second connecting part 102 to ensure that the second connecting part 102 does not loosen due to stress rotation when connected to the second joint 40.

[0080] The first joint 10 is designed as a detachable connection structure, when any part fails or needs to be maintained, it can be conveniently disassembled and replaced without replacing the entire joint, which not only reduces the maintenance cost, but also prolongs the overall service life of the joint. At the same time, the design of the fastening member 30 abutting against the second connecting part 102 significantly enhances the connection stability between the second connecting part 102 and the adjacent components (such as the second joint 40 or the joint fixing member 20). Through the fastening action of the fastening member 30, the second connecting part 102 is firmly fixed in place, effectively preventing connection loosening or displacement due to vibration, external force impact or pressure change, thereby ensuring the stability and reliability of the entire pipeline connection assembly 1.

[0081] Further, as shown in Figure 2 and Figure 4 The pipeline connection assembly 1 further comprises a pipeline mounting member 60 and a positioning pin 70, the positioning pin 70 is arranged between the joint fixing member 20 and the pipeline mounting member 60, and the positioning pin 70 is used to assist the joint fixing member 20 to locate the pipeline mounting member 60.

[0082] The positioning pin 70 is arranged between the joint fixing member 20 and the pipe mounting member 60, and mainly serves to assist the joint fixing member 20 to be directly or indirectly fixed to the pipe mounting member 60. By inserting the positioning pin 70, displacement or deflection of the joint fixing member 20 and the pipe mounting member 60 during assembly and assembly can be effectively prevented, thereby ensuring the overall stability and safety of the pipeline connection assembly 1. Specifically, the positioning pin 70 can be fixed to the joint fixing member 20 and / or the pipe mounting member 60 by threaded connection, insertion, press fitting or other suitable fixing methods. The shape of the positioning pin 70 should facilitate insertion and fixation, while providing good positioning effect. Common shapes include cylindrical, conical or chamfered shapes to facilitate installation and reduce stress concentration.

[0083] The material of the positioning pin 70 has high strength, wear resistance and corrosion resistance, and can be stainless steel, alloy steel or special alloy material, which ensures that the positioning pin 70 maintains stable performance during long-term use. In order to further improve the corrosion resistance and service life of the positioning pin 70, the surface of the positioning pin 70 can be treated by galvanizing, sandblasting or coating with a corrosion-resistant coating. The position and number of the positioning pin 70 should be determined according to the specific needs of the pipe 50 system and the size of the joint fixing member 20, which is not limited here.

[0084] In the process of fixing the joint fixing member 20 to the pipe mounting member 60, the first joint 10 needs to be tightly connected to the pipe 50, and then the joint fixing member 20 is sleeved outside the first joint 10. Since there is a gap between the joint fixing member 20 and the first joint 10, the joint fixing member 20 and the first joint 10 are prone to twist in the second direction. Therefore, the positioning pin 70 is arranged between the joint fixing member 20 and the pipe mounting member 60, which serves to guide the installation of the joint fixing member 20 and ensure the accurate positioning of the joint fixing member 20, while also enhancing the ability of the joint fixing member 20 to withstand torsion.

[0085] Since the pipe mounting member 60 and the joint fixing member 20 are connected by the positioning pin 70, the accurate positioning of the joint fixing member 20 can be ensured, and the installation of the joint fixing member 20 is facilitated. At the same time, due to the arrangement of the positioning pin 70, the ability of the joint fixing member 20 to withstand torsion is enhanced, thereby improving the stability of the pipe 50 and the joint.

[0086] As Figure 2 and Figure 4As shown, the positioning pin 70 is integrally formed with the pipe mounting member 60, and the joint fixing member 20 is provided with a first positioning hole 202 corresponding to the positioning pin 70, and the positioning pin 70 is inserted into the first positioning hole 202; or, the positioning pin 70 is integrally formed with the joint fixing member 20, and the pipe mounting member 60 is provided with a second positioning hole 601 corresponding to the positioning pin 70, and the positioning pin 70 is inserted into the second positioning hole 601; or, the positioning pin 70 is a separate structure, the joint fixing member 20 is provided with the first positioning hole 202, the pipe mounting member 60 is provided with the second positioning hole 601, one end of the positioning pin 70 is inserted into the first positioning hole 202, and the other end of the positioning pin 70 is inserted into the second positioning hole 601.

[0087] The cooperation between the positioning pin 70 and the pipe mounting member 60 and the joint fixing member 20 can be achieved in the following three ways.

[0088] Technical solution one: the positioning pin 70 is integrally formed with the pipe mounting member 60. The positioning pin 70 is arranged on the side of the pipe mounting member 60 close to the joint fixing member 20, and the positioning pin 70 is an integral part of the pipe mounting member 60 and cannot be detached or can be detached (according to the specific design). The joint fixing member 20 is provided with a first positioning hole 202 matching the shape and size of the positioning pin 70. In the installation process, the pipe mounting member 60 is aligned with the joint fixing member 20, the positioning pin 70 is inserted into the first positioning hole 202, and then the fastening member is penetrated through the joint fixing member 20 and abuts against the first joint 10. Since this way does not need to set an additional positioning pin 70, the structure is compact, the number of parts is reduced, and the installation process is simplified.

[0089] Technical solution two: the positioning pin 70 is integrally formed with the joint fixing member 20, and the positioning pin 70 is arranged on the side of the joint fixing member 20 close to the pipe mounting member 60. The positioning pin 70 is an integral part of the joint fixing member 20 and cannot be detached or can be detached (according to the specific design). The pipe mounting member 60 is provided with a second positioning hole 601 matching the shape and size of the positioning pin 70. In the installation process, the joint fixing member 20 is aligned with the pipe mounting member 60, the positioning pin 70 is inserted into the second positioning hole 601, and then the fastening member 30 is penetrated through the joint fixing member 20 and abuts against the first joint 10. Since this way does not need to set an additional positioning pin 70, the structure is compact, the number of parts is reduced, and the installation process is simplified. At the same time, this way can make the structure of the joint fixing member 20 more stable.

[0090] Technical solution three: the positioning pin 70 is a completely independent structural member, which can be manufactured and replaced separately. The positioning pin includes a first positioning part 701, a third connecting part 702, and a second positioning part 703. The joint fixing member 20 is provided with a first positioning hole 202, and the pipe mounting member 60 is provided with a second positioning hole 601. The shapes and sizes of the two positioning holes are matched with the positioning pin 70. During installation, the first positioning part 701 is first inserted into the second positioning hole 601, and then the joint fixing member 20 is aligned with the second positioning part 703, so that the second positioning part 703 is inserted into the first positioning hole 202, and the indirect connection of the joint fixing member and the pipe mounting member is completed. Since the positioning pin 70 is an independent structural member, it is convenient to replace and maintain, and has higher flexibility, and can be customized according to different pipe mounting members 60 and joint fixing members 20.

[0091] Further, as shown in Figure 2 and Figure 4 , the pipe connection assembly 1 includes a plurality of positioning pins 70, and the plurality of positioning pins 70 are arranged on both sides of the pipe 50.

[0092] In order to further enhance the stability and accuracy of the pipe 50 connection, the pipe connection assembly 1 has a plurality of positioning pins 70, and the plurality of positioning pins 70 are arranged on both sides of the pipe 50, which aims to more accurately install the joint fixing member 20 on the pipe mounting member 60, thereby ensuring the stability and accuracy during installation.

[0093] The plurality of positioning pins 70 can be uniformly distributed along the vertical direction of the central axis of the first joint 10. On the one hand, it can ensure that stable support and positioning can be provided in the entire connection area. On the other hand, since the pipe 50 can be subjected to lateral force or torque, the positioning pin 70 can also effectively resist these forces, thereby further enhancing the connection stability of the pipe 50.

[0094] The positioning pin 70 can also be non-uniformly distributed along the vertical direction of the central axis of the first joint 10. By unevenly arranging, the installation direction of the joint fixing member 20 can be accurately distinguished and guided. In addition, different sizes, or heights, and / or shapes of the positioning pin 70 can also be used to distinguish the installation direction of the joint fixing member 20.

[0095] Since there are a plurality of positioning pins 70 arranged on both sides of the pipe 50, during the tightening of the fastening member 30, it is not necessary to hold the joint fixing member 20 by hand, which facilitates installation operation, and at the same time, the torsional force that the joint fixing member 20 can withstand is doubled, thereby improving the connection stability of the pipe 50 and the first joint 10.

[0096] Further, as shown in Figures 1 to 5As shown, the pipeline connecting assembly 1 further comprises a pipe fixing member 80, which is located between the pipe mounting member 60 and the joint fixing member 20, and the joint fixing member 20 is fixed to the pipe mounting member 60 through the pipe fixing member 80.

[0097] The pipe fixing member 80 is installed between the pipe mounting member 60 and the joint fixing member 20, and plays a role of fixing and connecting.

[0098] On the one hand, the pipe fixing member 80 is provided with a through hole for the pipe 50 to pass through, which is used to fix the pipe 50. Optionally, the through hole is provided with a fixing part for fixing the pipe 50, which can prevent the pipe 50 from being displaced when the pipe 50 is connected with the first joint 10, thereby affecting the connection of the pipe 50 with the first joint 10. For example, if the fixing part is a groove, the pipe 50 is provided with a protrusion, and when the pipe 50 is installed in the pipe fixing member 80, the cooperation of the clamping groove and the protrusion makes the pipe 50 fixed to the pipe fixing member 80.

[0099] On the other hand, the pipe fixing member 80 is also used to indirectly fix the joint fixing member 20 to the pipe mounting member 60 to form a stable connection of the entire pipeline connecting assembly 1. For example, if the positioning pin 70 is a separate structural member including a first positioning part 701 and a second positioning part 703, during the installation and fixing process, the first positioning part 701 is first inserted into the second positioning hole 601, then the pipe 50 is penetrated into the pipe fixing member 80 through the positioning pin 70, the pipe fixing member 80 is fixedly connected with the pipe mounting member 60 through the fastener, and finally the second positioning part 703 is inserted into the first positioning hole 202, and the joint fixing member 20 is fixedly connected with the pipe fixing member 80 through the fastener.

[0100] The shape and size of the pipe fixing member 80 need to be adapted to the pipe mounting member 60 and the joint fixing member 20, so as to ensure the close connection and stable fixation therebetween. The pipe fixing member 80 can be made of high-strength material, such as stainless steel, to ensure that it can withstand various external forces in the pipeline system and maintain long-term stable operation.

[0101] It is worth mentioning that the positioning pin 70 can also be provided on the pipe fixing member 80, for example, it can be integrally formed with the pipe fixing member 80 or detachably connected with the pipe fixing member 80. Specifically, the pipe fixing member 80 is provided with a first positioning part 701 on the side close to the pipe mounting member 60, and a second positioning part 703 on the side close to the joint fixing member 20. During the installation of the joint fixing member 20, the first positioning pin 70 is first inserted into the second positioning hole 601 provided on the pipe mounting member 60, then the pipe fixing member 80 is fixed with the pipe mounting member 60, then the second positioning pin 70 is inserted into the first positioning hole 202 of the joint fixing member 20, and finally the joint fixing member 20 is fixed with the pipe fixing member 80.

[0102] Since the joint fixing piece 20 is fixed to the pipe mounting piece 60 through the pipe fixing piece 80, the pipe fixing piece 80 is made of high-strength material, which can enhance the fixing strength, facilitate repeated disassembly of the joint fixing piece 20, and further improve the convenience of assembly.

[0103] Further, as shown in Figure 2 The pipe fixing piece 80 is provided with a second through hole 801 for the positioning pin 70 to pass through, and through the cooperation of the positioning pin 70 and the second through hole, the joint fixing piece 20, the pipe fixing piece 80 and the pipe mounting piece 60 are precisely aligned.

[0104] Since the pipe fixing piece 80 is located between the joint fixing piece 20 and the pipe mounting piece 60, and the positioning pin 70 abuts against the pipe fixing piece 80 and the pipe mounting piece 60, the second through hole 801 for the positioning pin 70 to pass through is arranged on the pipe fixing piece 80, and the positioning pin 70 is connected to the joint fixing piece 20, the pipe fixing piece 80 and the pipe mounting piece 60, so that the positioning pin 70 precisely aligns the joint fixing piece 20, the pipe fixing piece 80 and the pipe fixing piece 20.

[0105] The second through hole 801 has a specific inner diameter size, which needs to ensure that the outer diameter of the positioning pin 70 can easily pass through, but at the same time it cannot be too loose. Specifically, the outer diameter of the positioning pin 70 is designed to be slightly smaller than the inner diameter of the second through hole 801, which ensures that the positioning pin 70 can be smoothly inserted into the second through hole 801 and will not be jammed due to the size being too large, and ensures that the positioning pin 70 still has a certain activity space in the second through hole 801 after being inserted, so as to facilitate fine adjustment or adapt to size changes caused by factors such as thermal expansion and cold contraction.

[0106] At the same time, in order to avoid unnecessary rotation or sliding of the positioning pin 70 in the second through hole 801, an anti-slip structure such as a small protrusion, groove or texture can be arranged on the surface of the positioning pin 70 or the inner wall of the second through hole 801.

[0107] In addition, in order to further improve the stability and reliability of the connection, an enlarged head or buckle structure can be designed on the outer surface of the positioning pin 70. When the positioning pin 70 is completely inserted into the second through hole 801, the enlarged head or buckle structure can be clamped to the inner wall of the pipe fixing piece 80, preventing the positioning pin 70 from easily coming out due to external force.

[0108] Since the positioning pin 70 connects the joint fixing part 20, the pipeline fixing part 80 and the pipeline mounting part 60 together, the joint fixing part 20, the pipeline fixing part 80 and the pipeline mounting part 60 are positioned in both the first direction and the second direction, so that the precise positioning between the joint fixing part 20, the pipeline fixing part 80 and the pipeline mounting part 60 can be realized, and the stability and connection precision of the entire pipeline connection assembly 1 are ensured.

[0109] Further, as shown in Figure 2 the second through hole 801 is a stepped hole, and the positioning pin 70 is provided with a step corresponding to the stepped hole.

[0110] The second through hole 801 designed on the pipeline fixing part 80 is a stepped hole structure. Such a stepped hole is composed of two or more hole segments with different diameters, forming one or more stepped surfaces. This design not only enhances the structural strength of the hole, but also provides convenience for subsequent installation and positioning.

[0111] At the same time, in order to match with such a stepped hole structure, the positioning pin 70 has a corresponding stepped structure. The diameter of the positioning pin 70 changes at different positions, matching the diameters of the hole segments of the stepped hole. When the positioning pin 70 is inserted into the stepped hole, the thinner part can smoothly enter the smaller hole segment, while the thicker part fits with the larger hole segment, thereby forming stable support and positioning on the stepped surface.

[0112] Optionally, the stepped structure of the positioning pin 70 can include one or more stepped surfaces with gradually increasing diameters, each corresponding to a hole segment in the stepped hole. This arrangement ensures that the positioning pin 70 can be securely clamped in the stepped hole during insertion and will not easily loosen or fall off when the joint fixing part 20 is disassembled.

[0113] In addition, in order to further improve the positioning accuracy and stability, an anti-slip structure or coating can be provided on the contact surface between the positioning pin 70 and the stepped hole, such as threads, grooves, rubber coating, etc. These structures can increase the friction between the two, preventing the positioning pin 70 from sliding or rotating in the stepped hole.

[0114] Designing the second through hole 801 as a stepped hole means that the inner wall of the hole has different diameter segments, forming a stepped structure. The positioning pin 70 is provided with a step corresponding to the stepped hole. When the positioning pin 70 is inserted into the second through hole 801, the step and the different diameter segments of the stepped hole can form a close fit. This fit not only increases the contact area, but also provides more frictional resistance, effectively preventing the positioning pin 70 from loosening or slipping in the second through hole 801, thereby facilitating the disassembly operation of the joint fixing part 20 and improving the overall connection stability.

[0115] Further, as shown in Figure 2As shown, the pipe mounting member 60 or the joint fixing member 20 is provided with a mounting position 602, and the pipe fixing member 80 is mounted on the mounting position 602. The mounting position 602 is used to limit the pipe fixing member 80.

[0116] The mounting position 602 is a position for mounting or fixing the pipe fixing member 80, which can be arranged on the pipe mounting member 60 or the joint fixing member 20. By arranging the mounting position 602 on the pipe mounting member 60 or the joint fixing member 20, a stable and precise mounting environment is provided for the pipe fixing member 80, ensuring that it can be firmly fixed in the predetermined position and effectively support and limit the pipe 50.

[0117] The mounting position 602 is arranged on the end of the pipe mounting member 60 close to the pipe fixing member 80, or on the end of the joint fixing member 20 close to the pipe mounting member 60. The shape and size of the mounting position 602 match those of the pipe fixing member 80, to ensure that the pipe fixing member 80 can be tightly embedded therein and will not shake or loosen due to size mismatch. At the same time, the inner wall of the mounting position 602 is also appropriately treated, such as adding an anti-slip structure or coating, to further enhance the friction between the pipe fixing member 80 and the mounting position 602 and improve its stability.

[0118] In addition, the mounting position 602 is also designed with limiting structures for precisely limiting the pipe fixing member 80. These limiting structures can be protruding blocks, grooves, threads, etc., which cooperate with the corresponding structures on the pipe fixing member 80 to ensure that the pipe fixing member 80 can only be installed in the mounting position 602 according to the predetermined direction and position, and cannot be moved or rotated at will. This limiting design not only improves the accuracy of installation, but also prevents problems such as fluid leakage or pipe 50 damage caused by position deviation of the pipe fixing member 80.

[0119] Since the pipe mounting member 60 is provided with the mounting position 602 for limiting the pipe fixing member 80, the pipe fixing member 80 can be fixedly connected to the pipe mounting member 60 through the first fixing member 90, thereby improving the connection strength of the pipe fixing member 80.

[0120] Further, as shown in Figure 2 , Figure 3 and Figure 4 , the mounting position 602 is a groove.

[0121] The installation site 602 is a groove, the shape and size of which are matched with the shape and size of the pipe fixing member 80 to ensure that the pipe fixing member 80 can be closely embedded in the groove and cannot shake or loosen due to size mismatch. Optionally, the depth of the groove can be slightly smaller than the size of the pipe fixing member 80 in the first direction, so that the pipe fixing member 80 can be embedded as much as possible, and the problem of difficulty in disassembly or damage to the pipe fixing member 80 or the pipe mounting member 60 caused by excessive depth can be avoided.

[0122] In addition, a limiting structure such as a protruding clamping block, a positioning pin in the groove, etc. can be arranged at a proper position of the groove to accurately limit the pipe fixing member 80 and prevent it from moving or rotating during installation. The limiting structure should cooperate with the corresponding structure on the pipe fixing member 80 to ensure reliable limiting effect and easy installation.

[0123] Since the installation site 602 of the pipe mounting member 60 is in the form of a groove, the pipe fixing member 80 will not excessively protrude from the pipe mounting member 60 after installation, thereby facilitating the installation of the pipe fixing member 80 between the joint fixing member 20 and the pipe mounting member 60 and ensuring the stability and accuracy of the installation.

[0124] Further, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the pipe connection assembly 1 further comprises at least one first fixing member 90 and at least one second fixing member 100, the pipe fixing member 80 is fixedly connected with the pipe mounting member 60 through the first fixing member 90, and the joint fixing member 20 is fixedly connected with the pipe fixing member 80 through the second fixing member 100; or / and, the pipe connection assembly 1 comprises at least one third fixing member (not shown in the figure), and the joint fixing member 20 and the pipe fixing member 80 are both fixedly connected with the pipe mounting member 60 through the third fixing member (not shown in the figure).

[0125] Indirectly fixing the joint fixing member 20 to the pipe mounting member 60 can be achieved in the following two ways:

[0126] The first mode: the stable connection between the pipe fixing member 80, the joint fixing member 20 and the pipe mounting member 60 is achieved by containing at least one first fixing member 90 and at least one second fixing member 100. Specifically, the pipe fixing member 80 is connected with the pipe mounting member 60 by means of the first fixing member 90, and the joint fixing member 20 is fixedly connected with the pipe fixing member 80 by means of the second fixing member 100. Since the pipe fixing member 80 is fixedly connected with the pipe mounting member 60 by means of the first fixing member 90, and the joint fixing member 20 is fixedly connected with the pipe fixing member 80 by means of the second fixing member 100, the joint fixing member 20 and the pipe mounting member 60 are indirectly connected, the rigidity of the joint fixing member 20 is improved, and the stability of the whole is improved.

[0127] The second mode: the integrated connection between the joint fixing member 20, the pipe fixing member 80 and the pipe mounting member 60 is achieved by containing at least one third fixing member (not shown in the drawings). The joint fixing member 20 is provided with an opening, the pipe fixing member 80 and the pipe mounting member 60 are provided with openings at corresponding positions, and the third fixing member (not shown in the drawings) is inserted and fixed from top to bottom. Since the pipe fixing member 80 and the pipe mounting member 60 are fixed by the third fixing member (not shown in the drawings), and the joint fixing member 20 and the pipe fixing member 80 are fixedly connected by the third fixing member (not shown in the drawings), only one fixing member is needed to achieve the connection and fixation of the three structural members, thereby simplifying the installation process, reducing the number of required fixing members, reducing the installation difficulty and cost, and improving the assembly efficiency.

[0128] Further, as shown in Figures 1 to 5 If the pipe fixing member 80 is fixedly connected with the pipe mounting member 60 by means of the first fixing member 90, and the joint fixing member 20 is fixedly connected with the pipe fixing member 80 by means of the second fixing member 100, the first fixing member 90 and the second fixing member 100 are arranged at different positions on the preset projection plane.

[0129] In the embodiment of the present application, the preset projection plane is a plane perpendicular to the central axis of the first joint 10, which is used to determine and describe the relative position relationship between the first fixing member 90 and the second fixing member 100.

[0130] If the first fixing member 90 and the second fixing member 100 overlap on the preset projection plane, the fixing holes in the pipe fixing member 80 cannot be effectively fixed at the same time. Specifically, the pipe fixing member 80 plays a role of connecting the upstream and downstream in the pipe connection assembly 1. On the one hand, the pipe fixing member 80 needs to be stably and fixedly connected with the pipe mounting member 60 through the first fixing member 90 to ensure the stability and safety of the pipe. On the other hand, the pipe fixing member 80 needs to be connected with the joint fixing member 20 through the second fixing member 100 to realize smooth connection and fluid transmission between the pipes. However, in actual application, if the first fixing member 90 and the second fixing member 100 overlap on the preset projection plane, a fixing hole conflict problem will be caused. Because the number and position of the fixing holes on the pipe fixing member 80 are limited, if the positions of the two fixing members overlap, it means that they will compete for the same or the same group of fixing holes, thereby causing the effective fixed connection cannot be realized at the same time.

[0131] Therefore, on the preset projection plane, the first fixing member 90 and the second fixing member 100 do not overlap, and each occupies a position. This arrangement can not only ensure that the pipe fixing member 80 and the joint fixing member 20 can be stably and firmly connected, but also can avoid the problem of difficult installation or unstable connection caused by overlapping positions, thereby improving the stability of the connection.

The two ends of the pipe 50 can be connected with other components through the pipe connection assembly 1. The pipe connection assembly 1 as a key part of the fluid transmission device 2 is responsible for connecting and sealing each part in the system, ensuring the sealing and smoothness of the fluid in the transmission process.

[0134] Due to the above-mentioned pipe connection assembly 1, the stability of the connection between the pipe 50 and the first joint 10 can be ensured, and the problems of loose connection and leakage caused by vibration, pressure change, and external second joint 40 disassembly can be effectively avoided, thereby improving the reliability of the overall fluid transmission device 2.
