Description

Technical Field

[0001] This utility model belongs to the field of fire protection engineering technology, and in particular relates to an auxiliary structure for the installation of fire protection engineering facilities. Background Technology

[0002] In the field of fire protection engineering, fire protection pipelines serve as crucial channels connecting various fire protection equipment and materials, and transporting fire-fighting water, gas, or other media. The quality of their installation directly affects the reliability and effectiveness of the entire fire-fighting system. During the installation of fire protection pipelines, adjacent pipe sections are typically sealed together using sealing rings and pipe clamps. This connection method requires precise assembly of the connecting components to ensure sealing and structural stability.

[0003] Currently, connectors used for fire protection pipe connections face significant technical challenges during assembly. Existing connectors lack specialized assembly tools, making it difficult to accurately insert the snap-fit ​​portion of the connector into the correct angle of the snap-fit ​​opening. Furthermore, after pipe connection, operators can only visually inspect the connection's appearance. Due to the concealed nature of the connection structure, it's impossible to visually determine whether the internal insertion is correct. This inspection method has significant limitations and struggles to effectively detect potential assembly defects. These problems not only affect the efficiency of fire protection pipe installation but also potentially lead to leaks, loose connections, and other hazards due to improper connections, seriously threatening the normal operation of the fire protection system and fire safety. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing an auxiliary structure for the installation of fire protection engineering facilities that allows for visual inspection of the installation and connection of fire protection pipelines from the outside.

[0005] In view of this, the present invention provides an auxiliary structure for the installation of fire protection engineering facilities, comprising:

[0006] Firefighting pipelines;

[0007] Connecting components are used to connect and cooperate with adjacent pipe sections of the fire protection pipeline;

[0008] The connection component includes:

[0009] Connecting pipe body, installed at the outer end of fire protection pipeline;

[0010] A sleeve, fitted over the outer surface of the connecting pipe;

[0011] The locking block consists of multiple blocks, symmetrically arranged on the outer surface of the connecting tube.

[0012] The protruding part is located at the front end of the sleeve and protrudes outward from the inside of the sleeve, with the outer surface of the protruding part being higher than the outer surface of the sleeve.

[0013] A snap-in opening is located inside the protruding part;

[0014] An elastic component is disposed inside the snap-fit ​​opening. The elastic component engages with the snap-fit ​​block to provide elastic force that keeps the snap-fit ​​block in a locked state.

[0015] An angle positioning component, installed on the connecting pipe body and the sleeve, is used to accurately position the relative angle between the locking block and the snap-in opening.

[0016] In the above technical solution, the elastic component is further defined as a spring sheet.

[0017] In any of the above technical solutions, the angle positioning component further includes:

[0018] The outer ring is located on the outside of the connecting pipe body;

[0019] The limiting slots are formed on the outer ring, and there are multiple limiting slots distributed along the circumferential direction;

[0020] The guide block is set on the tube sleeve and inserted into the limiting slot. It is used to guide the tube sleeve to be inserted into the connecting tube body at the correct angle, so as to achieve precise docking of the block and the snap-fit ​​opening.

[0021] In any of the above technical solutions, a guide chamfer is further provided at the end of the guide block.

[0022] In any of the above technical solutions, a slot is further provided inside the connecting pipe, and the fire-fighting pipe is inserted into the slot.

[0023] In any of the above technical solutions, further, the rear end of the connecting pipe body is provided with an insert plate, the inner wall of the pipe sleeve is provided with an annular protrusion, the annular protrusion is arranged along the circumference of the pipe sleeve, an annular groove is provided between the annular protrusion and the pipe sleeve, and the insert plate is embedded in the annular groove, the insert plate is in contact with the inner wall of the annular groove.

[0024] In any of the above technical solutions, a sealing ring is further provided on the outer surface of the insert plate, and the sealing ring is embedded in the annular groove.

[0025] The beneficial effects of this utility model are:

[0026] 1. When connecting fire-fighting pipelines, the connecting pipe body is installed on the outer end of the fire-fighting pipeline, and the pipe sleeve is fitted on the outer surface of the connecting pipe body. The guide block on the pipe sleeve will interact with the limiting groove on the connecting pipe body to accurately position the angle relationship between the pipe sleeve and the connecting pipe body, ensuring that the locking block and the snap-in opening can be accurately aligned. This solves the problem that the snap-in part of the existing connector is difficult to insert into the snap-in opening at the correct angle, ensuring the precise assembly of the connecting components and improving the sealing performance and structural stability of the fire-fighting pipeline connection.

[0027] 2. Apply external force to the spring sheet using a tool. The spring sheet undergoes elastic deformation under the force, changing its shape and position to make room for the locking block to pass smoothly through the snap-fit ​​opening. Then, remove the external force applied to the spring sheet. The spring sheet returns to its initial shape and position and engages with the locking block to achieve a firm connection between the connecting pipe body and the pipe sleeve, thereby completing a reliable connection between adjacent pipe sections of the fire protection pipeline.

[0028] 3. By utilizing the characteristic that the outer surface of the protruding part is higher than the outer surface of the pipe sleeve, operators can intuitively observe the accuracy of the installation from the outside. This changes the previous situation where only visual inspection of the connection appearance was used and it was difficult to judge whether the internal insertion connection was correctly matched. It effectively discovers potential assembly defects, ensures the quality of fire protection pipeline installation, and thus ensures the normal operation of the fire protection system and fire safety.

[0029] 4. By opening slots inside the connecting pipe body, fire-fighting pipes can be inserted into them to form a nested connection, which increases the contact area and friction between the pipe and the connecting pipe body. This effectively prevents the fire-fighting pipes from loosening or shifting at the connection point, ensuring the structural stability of the entire fire-fighting pipe system. The tight insertion and fit help improve the sealing of the connection point, which can effectively prevent the leakage of fire-fighting water, gas or other media at the connection point.

[0030] 5. By embedding the insert plate into the annular groove, the connecting pipe body and the pipe sleeve are mutually restricted in the circumferential direction, effectively preventing relative rotation or misalignment between the two, enhancing the overall structural stability of the fire pipeline connection assembly. The sealing ring forms a tight sealing structure, effectively preventing the leakage of fire extinguishing water, gas or other media from the gap between the connecting pipe body and the pipe sleeve. This helps installers complete the assembly operation quickly and accurately, reducing assembly errors and improving installation efficiency. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0037] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] Example 1:

[0039] like Figures 1-4 As shown, this embodiment provides an auxiliary structure for the installation of fire protection engineering facilities, including:

[0040] Fire pipe 1;

[0041] Connection component 2 is connected and cooperates with the adjacent pipe section of fire protection pipeline 1;

[0042] The connection component 2 includes:

[0043] Connecting pipe 21 is installed at the outer end of fire-fighting pipe 1;

[0044] The sleeve 22 is fitted onto the outer surface of the connecting pipe body 21;

[0045] The locking block 23 has multiple blocks, which are symmetrically arranged on the outer surface of the connecting pipe body 21;

[0046] The protruding part 24 is provided at the front end of the sleeve 22 and protrudes outward from the inside of the sleeve 22. The outer surface of the protruding part 24 is higher than the outer surface of the sleeve 22.

[0047] A snap-in opening 25 is located inside the protruding portion 24;

[0048] The elastic member 26 is disposed inside the snap-fit ​​opening 25. The elastic member 26 engages with the snap-fit ​​block 23 to provide elastic force to keep the snap-fit ​​block 23 in a locked state.

[0049] Angle positioning component 3 is installed on the connecting tube body 21 and the sleeve 22 to accurately position the relative angle between the locking block 23 and the snap-in opening 25.

[0050] In this technical solution, the angle positioning component 3 precisely positions the relative angle between the locking block 23 and the snap-fit ​​opening 25, solving the problem that existing connectors have difficulty inserting the snap-fit ​​part into the snap-fit ​​opening 25 at the correct angle. This ensures precise assembly of the connecting components and improves the sealing performance and structural stability of the fire-fighting pipeline 1 connection. Utilizing the characteristic that the outer surface of the protruding part 24 is higher than the outer surface of the sleeve 22, operators can visually observe the accuracy of the installation from the outside. This changes the previous situation where only visual inspection of the connection appearance was possible, making it difficult to determine whether the internal insertion connection was correctly matched. It effectively detects potential assembly defects, ensures the installation quality of the fire-fighting pipeline 1, and thus ensures the normal operation of the fire protection system and fire safety.

[0051] Working Principle: When connecting the fire-fighting pipe 1, the connecting pipe body 21 is first installed on the outer end of the fire-fighting pipe 1, and the pipe sleeve 22 is fitted onto the outer surface of the connecting pipe body 21. At this time, the angle positioning component 3 begins to function, accurately determining the relative angle between the locking block 23 and the snap-fit ​​opening 25, providing an accurate angular reference for subsequent snap-fit ​​operations. The locking blocks 23 are symmetrically arranged on the outer surface of the connecting pipe body 21, and the snap-fit ​​opening 25 is located inside the protruding part 24. During the connection operation, a specific tool is used to deform the elastic component 26 inside the snap-fit ​​opening 25. After the elastic component 26 is deformed, the locking block 23 can smoothly pass through the snap-fit ​​opening 25. After the locking block 23 passes through the snap-fit ​​opening 25, the tool that deformed the elastic component 26 is removed, and the elastic component 26 returns to its original position. The returned elastic component 26 engages with the locking block 23, providing the locking block 23 with elastic force to maintain its locked state, thereby firmly connecting the connecting pipe body 21 and the pipe sleeve 22 together, achieving a sealed butt joint installation of adjacent pipe sections of the fire-fighting pipe 1. Since the outer surface of the protruding part 24 is higher than the outer surface of the sleeve 22, after the connection is completed, the operator can visually judge whether the internal locking block 23 and the snap-fit ​​opening 25 are correctly matched by observing the appearance of the protruding part 24, thereby checking whether the installation is accurate.

[0052] like Figures 2-4As shown, in this embodiment, the optimized elastic component 26 is a spring sheet.

[0053] In this technical solution, a spring clip is used as an elastic component 26 in the auxiliary structure for fire protection engineering installation. The main purpose is to better achieve reliable locking and convenient operation of the fire pipe 1 connection assembly 2. The spring clip has the characteristic of returning to its original shape after elastic deformation. When adjacent pipe sections of the fire pipe 1 are connected, it provides stable elastic force to the locking block 23, keeping the locking block 23 locked, ensuring the sealing and structural stability of the connection, preventing leakage due to loose connections, and ensuring the normal operation of the fire protection system. The spring clip can deform under external force applied by external tools. This deformation characteristic allows the locking block 23 to smoothly pass through the snap-fit ​​opening 25 during the connection process. After the locking block 23 is in place, the spring clip resets to achieve the snap-fit ​​connection, simplifying the assembly process and improving installation efficiency.

[0054] Working Principle: When the connecting assembly 2 of the fire-fighting pipe 1 is not being connected, the spring clip is in its natural state, installed inside the snap-fit ​​opening 25. Its shape and position prevent the snap-fit ​​block 23 from passing directly through the snap-fit ​​opening 25. When it is necessary to connect the connecting pipe body 21 to the pipe sleeve 22, an external force is applied to the spring clip using a tool. The spring clip undergoes elastic deformation under the force, changing its shape and position, thereby making room so that the snap-fit ​​block 23, which is set on the outer surface of the connecting pipe body 21, can pass smoothly through the snap-fit ​​opening 25. After the snap-fit ​​block 23 reaches the predetermined position through the snap-fit ​​opening 25, the external force applied to the spring clip is removed. The spring clip returns to its initial shape and position due to its own elasticity, engaging with the snap-fit ​​block 23 and providing elastic force to lock the snap-fit ​​block 23 in its current position. This achieves a firm connection between the connecting pipe body 21 and the pipe sleeve 22, thereby completing the reliable connection of adjacent pipe sections of the fire-fighting pipe 1.

[0055] like Figures 1-4 As shown, in this embodiment, the optimized angle positioning component 3 includes:

[0056] Outer ring 31 is located on the outside of the connecting pipe body 21;

[0057] A limiting slot 32 is formed on the outer ring 31. There are multiple limiting slots 32, which are distributed along the circumferential direction.

[0058] The guide block 33 is set on the sleeve 22 and is inserted into the limiting slot 32. It is used to guide the sleeve 22 to be inserted into the connecting tube 21 at the correct angle, so as to achieve precise docking of the locking block 23 and the snap-fit ​​opening 25.

[0059] In this technical solution, the angle positioning component 3 is mainly designed to address the problem of the connector's snap-fit ​​part being difficult to insert precisely into the snap-fit ​​opening 25 at the correct angle during the connection of the fire-fighting pipeline 1. Through the cooperation of the outer ring 31, the limiting groove 32, and the guide block 33, the angular relationship between the sleeve 22 and the connecting pipe body 21 is precisely positioned, ensuring accurate alignment between the snap-fit ​​block 23 and the snap-fit ​​opening 25. This improves the sealing performance and structural stability of the fire-fighting pipeline 1 connection, preventing non-standard connections due to angular deviations that could affect the normal operation of the fire-fighting system. Clear angle positioning allows installers to quickly and accurately assemble the sleeve 22 and the connecting pipe body 21, reducing the time spent repeatedly adjusting the angle and improving the installation efficiency of the fire-fighting pipeline 1.

[0060] Working principle: The outer ring 31 is fixedly set on the outside of the connecting pipe body 21, and multiple limiting slots 32 are evenly distributed on its circumference. The guide block 33 is installed on the pipe sleeve 22, corresponding to the limiting slots 32. When connecting the fire pipe 1, part of the pipe sleeve 22 is brought close to the connecting pipe body 21. Since the guide block 33 is set on the pipe sleeve 22, during the approach process, the guide block 33 will interact with the limiting slots 32 on the outer ring 31. The shape and size design of the guide block 33 allows it to be inserted precisely into the limiting slots 32. When the guide block 33 is accurately inserted into a certain limiting slot 32, the angle of the pipe sleeve 22 relative to the connecting pipe body 21 is precisely locked. At this time, the locking block 23 set on the connecting pipe body 21 and the snap-fit ​​opening 25 in the protruding part 24 on the pipe sleeve 22 are precisely aligned, ensuring that the locking block 23 can be smoothly inserted into the snap-fit ​​opening 25 at the correct angle, completing the accurate assembly of the fire pipe 1 connecting component 2.

[0061] like Figure 2 and Figure 3 As shown, in this embodiment, the guide block 33 is optimized by having a guide chamfer 4 at its end.

[0062] In this technical solution, during the assembly of the fire-fighting pipe 1 connecting component 2, when the pipe sleeve 22 approaches the connecting pipe body 21 and the guide block 33 approaches the limiting slot 32, the guide chamfer 4 comes into play. The beveled structure of the guide chamfer 4 provides a clear guiding direction for the docking of the guide block 33 and the limiting slot 32. Compared with the right-angle end, the chamfer can more naturally guide the guide block 33 into the limiting slot 32. Even if there is a certain angle deviation during insertion, it can be adjusted and corrected through the guiding effect of the chamfer. The chamfer allows the guide block 33 to gradually transition from surface contact to complete fit when it contacts the limiting slot 32, avoiding the large resistance generated by the direct collision of the right-angle ends, reducing the friction when the two are in contact, and allowing the guide block 33 to slide into the limiting slot 32 more easily, completing the precise assembly of the angle positioning component 3, and ensuring the accurate docking of the locking block 23 and the snap-fit ​​opening 25. This reduces the difficulty of inserting the guide block 33 into the limiting slot 32, allowing the guide block 33 to cooperate more smoothly with the limiting slot 32. It reduces problems such as jamming and bumping caused by poor insertion during assembly, improving assembly efficiency. It also prevents wear and deformation damage to the guide block 33 and limiting slot 32 due to hard collisions during assembly, extending the service life of the components and ensuring the long-term stable and reliable operation of the angle positioning assembly 3. This, in turn, guarantees the accuracy and stability of the fire-fighting pipeline 1 connection.

[0063] Example 2:

[0064] This embodiment provides an auxiliary structure for the installation of fire protection engineering facilities, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] like Figure 2 and Figure 3 As shown, in this embodiment, the connection pipe 21 is optimized to have a slot 5 inside, and the fire pipe 1 is inserted into the slot 5.

[0066] In this technical solution, a slot 5 is provided inside the connecting pipe body 21, allowing the fire-fighting pipe 1 to be inserted into it, forming a nested connection. This increases the contact area and friction between the pipe and the connecting pipe body 21, effectively preventing the fire-fighting pipe 1 from loosening or shifting at the connection point, ensuring the structural stability of the entire fire-fighting pipe 1 system, and guaranteeing the reliability of the fire protection system during operation. The slot 5 provides a clear positional reference for the installation of the fire-fighting pipe 1, allowing installers to intuitively insert the fire-fighting pipe 1 into the corresponding slot 5, reducing the difficulty of alignment during installation, improving installation efficiency, and ensuring the accuracy of the pipe connection. The tight insertion and fit help improve the sealing of the connection point. Combined with sealing components such as the sealing ring 8, it can effectively prevent the leakage of fire-fighting water, gas, or other media at the connection point, ensuring the normal operation and fire safety of the fire-fighting pipe 1 system.

[0067] Working Principle: Before installing the fire-fighting pipe 1, the connecting pipe body 21 is installed in a suitable position. A slot 5, pre-cut inside the connecting pipe body 21 to match the size of the fire-fighting pipe 1, is pre-drilled. One end of the fire-fighting pipe 1 is aligned with the slot 5 of the connecting pipe body 21. During installation, due to the guiding and positioning effect of the slot 5, the fire-fighting pipe 1 can be accurately inserted into the slot 5. During insertion, the fire-fighting pipe 1 fits tightly against the inner wall of the slot 5. The friction between them, as well as the squeezing effect of the sealing ring 8, firmly fixes the fire-fighting pipe 1 within the slot 5. After the fire-fighting pipe 1 is inserted into the slot 5, a tight nested connection structure is formed. At this point, the connecting pipe body 21 is not only connected to adjacent pipe sections through external connecting components 2 (such as pipe sleeve 22, clamping block 23, etc.), but also securely connected to the fire-fighting pipe 1 internally through the slot 5. This dual internal and external connection method greatly enhances the stability and sealing of the connection points of the fire-fighting pipe 1, ensuring that the fire-fighting pipe 1 system can safely and reliably transport fire-fighting media.

[0068] Example 3:

[0069] This embodiment provides an auxiliary structure for the installation of fire protection engineering facilities, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] like Figure 3 and Figure 4 As shown, in this embodiment, the optimized connection tube body 21 is provided with a plug plate 6 at the rear end, and the inner wall of the tube sleeve 22 is provided with an annular protrusion 7. The annular protrusion 7 is arranged along the circumference of the tube sleeve 22, and an annular groove 71 is provided between the annular protrusion 7 and the tube sleeve 22. The plug plate 6 is embedded in the annular groove 71, and the plug plate 6 is in contact with the inner wall of the annular groove 71.

[0071] In this technical solution, the insertion plate 6 is embedded in the annular groove 71, which restricts the connecting pipe body 21 and the pipe sleeve 22 in the circumferential direction, effectively preventing relative rotation or misalignment between the two. This enhances the overall structural stability of the fire pipeline 1 connecting assembly 2, avoids leakage and component detachment caused by loose connections, and ensures the normal operation of the fire protection system. The insertion plate 6 is in close contact with the inner wall of the annular groove 71, and together with other sealing components, it can further prevent the fire protection medium from leaking from the connection gap between the connecting pipe body 21 and the pipe sleeve 22, improving the sealing performance of the connection and ensuring the safety and reliability of the fire pipeline 1 system when transporting fire-fighting water, gas, and other media. The cooperation between the annular protrusion 7, the annular groove 71, and the insertion plate 6 provides a clear positioning reference for the assembly of the connecting pipe body 21 and the pipe sleeve 22, helping installers to complete the assembly operation quickly and accurately, reducing assembly errors, and improving installation efficiency.

[0072] Working Principle: An insert plate 6 is installed at the rear end of the connecting pipe body 21, and an annular protrusion 7 is machined on the inner wall of the sleeve 22, forming an annular groove 71 between the annular protrusion 7 and the inner wall of the sleeve 22. Before assembling the fire-fighting pipeline 1 connecting assembly 2, ensure that all components of the connecting pipe body 21 and the sleeve 22 are clean and intact. Bring a portion of the sleeve 22 close to the connecting pipe body 21, aligning the insert plate 6 at the rear end of the connecting pipe body 21 with the annular groove 71 on the inner wall of the sleeve 22. During the advancement of the sleeve 22, the insert plate 6 gradually embeds itself into the groove along the opening of the annular groove 71. Due to the guiding effect of the annular groove 71 on the insert plate 6, it ensures that the insert plate 6 accurately enters the groove and fits against the inner wall of the groove. When the insert plate 6 is fully embedded in the annular groove 71, the insert plate 6 is in close contact with the inner wall of the annular groove 71, restricting the relative rotation and displacement between the connecting pipe body 21 and the sleeve 22, achieving a stable connection between the two in the circumferential direction. Meanwhile, the tight fit between the insert plate 6 and the inner wall of the annular groove 71, together with other sealing measures, effectively prevents the fire-fighting medium from leaking from the connection gap, forming a reliable sealing structure to ensure the normal operation and fire safety of the fire-fighting pipeline 1 system.

[0073] like Figures 2-4 As shown, in this embodiment, the outer surface of the insert plate 6 is provided with a sealing ring 8, which is embedded in the annular groove 71.

[0074] In this technical solution, a sealing ring 8 is provided on the outer surface of the insert plate 6. The elastic deformation capability of the sealing ring 8 fills the tiny gap between the insert plate 6 and the inner wall of the annular groove 71, forming a tight sealing structure. This effectively prevents leakage of fire-fighting water, gas, or other media from the gap between the connecting pipe body 21 and the pipe sleeve 22, ensuring the sealing and safety of the fire-fighting pipeline 1 system. The sealing ring 8 has a certain degree of elasticity, which can buffer the impact force generated by media flow and pipeline vibration during the operation of the fire-fighting pipeline 1 system, reducing hard friction and collision between the connecting pipe body 21 and the pipe sleeve 22, reducing component wear, and extending the service life of the connecting assembly 2 of the fire-fighting pipeline 1. In actual assembly, there may be a situation where the dimensions of the insert plate 6 and the annular groove 71 are not perfectly matched. The presence of the sealing ring 8 can compensate for such minor assembly errors, ensuring that the insert plate 6 and the annular groove 71 always maintain a good sealing and connection effect.

[0075] Working principle: Before installation, the sealing ring 8 is pre-installed in the sealing groove on the outer surface of the insert plate 6. At this time, the sealing ring 8 is in its natural state, with its outer diameter slightly larger than the inner diameter of the annular groove 71, so as to generate compression deformation during assembly. When the connecting pipe body 21 and the sleeve 22 are assembled, as the insert plate 6 gradually inserts into the annular groove 71, the sealing ring 8 enters the groove along with the insert plate 6. During the insertion process, the sealing ring 8 is squeezed by the inner wall of the annular groove 71, undergoes elastic deformation, and tightly fits the outer surface of the insert plate 6 and the inner wall of the annular groove 71, filling the gap between them. After the insert plate 6 is fully inserted into the annular groove 71, the sealing ring 8 continues to maintain a state of compression deformation. Relying on its own elastic recovery force, a uniform and tight pressure is formed between the insert plate 6 and the annular groove 71, thereby achieving a sealing effect. During the operation of the fire-fighting pipeline 1 system, when the pressure of the medium inside the pipeline acts on the connection part, the sealing ring 8 will further tighten against the inner wall of the insert plate 6 and the annular groove 71 under the pressure, enhancing the sealing performance; at the same time, when the pipeline vibrates, the elasticity of the sealing ring 8 can absorb the vibration energy, reduce the relative displacement and wear between the connecting pipe body 21 and the pipe sleeve 22, and ensure the stable operation of the fire-fighting pipeline 1 connection component 2.

[0076] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
