Description

Technical Field

[0001] This utility model belongs to the field of quick connector technology, and in particular relates to a connector structure that can be quickly assembled and disassembled. Background Technology

[0002] As an important tool for mobile catering services, food trucks integrate multiple functions such as cooking, refrigeration, heating, and cleaning. These devices are connected through complex water, gas, or oil systems to form a complete food truck operating system. However, traditional food trucks often neglect ease of maintenance in their design. This results in significant time and effort being spent disassembling and reinstalling various connectors when repairing or replacing parts, which not only affects the operational efficiency of the food truck but also increases maintenance costs. Utility Model Content

[0003] To overcome the technical shortcomings of existing fast food truck operating systems, which require a lot of time and effort to disassemble and reinstall various connectors when repairing or replacing parts, this utility model provides a connector structure that can be quickly disassembled and assembled.

[0004] This utility model provides a quick-assembly and disassembly connector structure, including a first connecting part and a second connecting part. One end of the first connecting part is a first threaded connector and the other end is a tube. One end of the second connecting part is a second threaded connector and the other end is a double-layered cylindrical body. The bottom of the double-layered cylindrical body is sealed, and the inner cylinder is lower than the outer cylinder. A support spring is installed between the double-layered cylindrical bodies and is fixedly connected to the bottom of the double-layered cylindrical bodies. The tube is inserted between the double-layered cylindrical bodies, and the end of the tube is pressed against the support spring. Two arc-shaped notches are symmetrically opened on the outer cylinder of the double-layered cylindrical body, and two limiting clips are symmetrically fixedly connected to the tube. The bottom of the arc-shaped notch extends into a reverse snap-fit ​​groove, which is arranged along the axis of the double-layer cylindrical body. When the tube is inserted into the double-layer cylindrical body, it compresses the support spring. The two limiting snap-fit ​​posts slide along the two arc-shaped notch grooves to the bottom of the grooves, and under the elastic force of the support spring, the movement direction of the limiting snap-fit ​​posts in the reverse snap-fit ​​groove is opposite to the insertion direction of the tube. The double-layer cylindrical body and the tube are fastened together by the cooperation of the arc-shaped notch groove, the reverse snap-fit ​​groove and the limiting snap-fit ​​posts. A first sealing ring is fixedly embedded on the outer wall of the tube. When the tube is inserted into the double-layer cylindrical body, the first sealing ring is tightly fitted with the inner wall of the outer cylinder of the double-layer cylindrical body.

[0005] In the structure of this application, the first threaded connector and the tube body of the first connecting part are integral, and the second threaded connector and the double-layer cylindrical body of the second connecting part are integral. A support spring is fixedly connected between the double-layer cylindrical bodies, and the axes of the support spring, the double-layer cylindrical bodies, and the tube body are collinear. The tube body is inserted between the double-layer cylindrical bodies, and the limiting pin can move along the arc-shaped notch to the reverse locking groove. Under the elastic force of the support spring, the reverse locking groove and the limiting pin are locked together, thus achieving quick engagement of the first and second connecting parts. When disassembly is required, the tube body is first further inserted into the double-layer cylindrical body. At this time, the limiting pin can be withdrawn from the reverse locking groove. Then, the tube body and the double-layer cylindrical body are rotated relative to each other along the arc of the arc-shaped notch, allowing the limiting pin to quickly unscrew from the arc-shaped notch, achieving quick disassembly and separation of the first and second connecting parts. The reverse locking groove and the limiting pin cooperate to form a locking mechanism, ensuring the stability and safety of the first and second connecting parts after connection. The outer wall of the pipe body and the inner wall of the outer cylinder of the double-layered cylindrical body are sealed together by a first sealing ring. The quick-connect and detachable connector structure can connect water pipes, gas pipes, and oil pipes. That is, the first and second connecting parts of the connector structure are connected to the two pipe sections respectively, and then the first and second connecting parts are assembled to enable the two pipe sections to be quickly connected.

[0006] This connector structure features a standardized design with uniform dimensions and shape, facilitating quick connection and disconnection between different components. It can also connect to interfaces of water pumps, solenoid valves, etc., enabling rapid insertion and removal of modular structures such as pumps and solenoid valves from pipelines. Thus, when repairing or replacing specific modular structures, only the faulty module needs to be quickly removed from the system, and the new modular structure can be connected, eliminating the need for large-scale disassembly and reinstallation of the entire system. Furthermore, visual labels or guides can be affixed to the pipelines near the connector structure or to the modular structure itself, helping maintenance personnel quickly identify the direction from which to disassemble and assemble specific connections, ensuring rapid maintenance, reducing operational difficulty, and improving maintenance efficiency.

[0007] Preferably, a second sealing ring is fixedly embedded on the outer wall of the inner cylinder of the double-layered cylindrical body. When the tube is inserted into the double-layered cylindrical body, the second sealing ring fits tightly with the inner wall of the tube. The first sealing ring and the second sealing ring are located on the outer wall and inner wall of the tube, respectively. This further prevents leakage between the tube and the double-layered cylindrical body, and further improves the sealing performance of the connector structure.

[0008] Preferably, sealing gaskets are respectively placed on the first threaded connector of the first connection portion and the second threaded connector of the second connection portion. The use of sealing gaskets improves the sealing performance between the first and second connection portions and the pipeline. In addition, waterproof PTFE tape can be wrapped around the first and second threaded connectors to further enhance the sealing effect at the connection.

[0009] Preferably, the support spring is a brass spring or a stainless steel spring. Both brass and stainless steel springs are corrosion-resistant, preventing the support spring from rusting and corroding in liquid environments and extending the service life of the connector structure.

[0010] Preferably, a limiting ring extends circumferentially from the outer wall of the inner cylinder of the double-layered cylindrical body to prevent the support spring from slipping. The thickness of the tube is less than the distance between the limiting ring and the inner wall of the outer cylinder of the double-layered cylindrical body, so that the front end of the tube abuts against the support spring after passing the limiting ring. The support spring is always in a compressed state under the action of the limiting ring. When the front end of the tube abuts against the support spring after passing the limiting ring, the support spring is further compressed, thereby enabling the support spring to exert an elastic force on the tube along the axial direction of the tube.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following technical effects: The connector structure of this utility model can achieve quick assembly and disassembly. The reverse snap-fit ​​groove and the limiting snap-fit ​​post cooperate to form a locking mechanism, ensuring the stability and safety of the first and second connecting parts after connection. Moreover, by using the connector structure in a food truck, quick assembly and disassembly of different modular structures can be achieved, which can significantly improve maintenance efficiency, shorten maintenance time, reduce labor and material costs in the maintenance process, reduce the overall operating cost of the food truck, and improve the reliability of the overall structure of the food truck operation system.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0020] The following is in conjunction with the appendix Figure 1 and attached Figure 2 The specific embodiments of this utility model will be described in detail below.

[0021] In one embodiment, such as Figure 1As shown, a quick-assembly and disassembly connector structure is disclosed, including a first connecting part 1 and a second connecting part 2. One end of the first connecting part 1 is a first threaded connector 3 and the other end is a tube body 4. One end of the second connecting part 2 is a second threaded connector 5 and the other end is a double-layered cylindrical body 6. The bottom of the double-layered cylindrical body 6 is sealed, and the inner cylinder is lower than the outer cylinder. A support spring 7 is assembled between the double-layered cylindrical bodies 6 and is fixedly connected to the bottom of the double-layered cylindrical bodies 6. The tube body 4 is inserted between the double-layered cylindrical bodies 6, and the end of the tube body 4 is pressed against the support spring 7. Two arc-shaped notches 8 are symmetrically opened on the outer cylinder of the double-layered cylindrical body 6, and two limiting pins 9 are symmetrically fixedly connected on the tube body 4. The bottom of the groove 8 extends into a reverse snap-fit ​​groove 10, which is arranged along the axis of the double-layer cylindrical body 6. When the tube body 4 is inserted into the double-layer cylindrical body 6, it compresses the support spring 7. The two limiting pins 9 slide along the two arc-shaped notch grooves 8 to the bottom of the grooves. Under the elastic force of the support spring 7, the direction of movement of the limiting pins 9 in the reverse snap-fit ​​groove 10 is opposite to the insertion direction of the tube body 4. The double-layer cylindrical body 6 and the tube body 4 are tightly connected by the cooperation of the arc-shaped notch groove 8, the reverse snap-fit ​​groove 10 and the limiting pins 9. A first sealing ring 11 is fixedly embedded on the outer wall of the tube body 4. When the tube body 4 is inserted into the double-layer cylindrical body 6, the first sealing ring 11 is tightly fitted with the inner wall of the outer cylinder of the double-layer cylindrical body 6.

[0022] In the structure of this application, the first threaded connector 3 and the tube body 4 of the first connecting part 1 are integral, and the second threaded connector 5 and the double-layer cylindrical body 6 of the second connecting part 2 are integral. The support spring 7 is fixedly connected between the double-layer cylindrical bodies 6, and the axes of the support spring 7, the double-layer cylindrical body 6, and the tube body 4 are collinear. The tube body 4 is inserted between the double-layer cylindrical bodies 6, and the limiting pin 9 can move along the arc-shaped notch 8 to the reverse locking groove 10. Under the elastic force of the support spring 7, the reverse locking groove 10 is locked with the limiting pin 9, thereby realizing the quick locking of the first connecting part 1 and the second connecting part 2. When disassembly is required, the tube body 4 is first further inserted into the double-layer cylindrical body 6. At this time, the limiting pin 9 can be withdrawn from the reverse locking groove 10. Then, the tube body 4 and the double-layer cylindrical body 6 are rotated relative to each other along the arc of the arc-shaped notch 8. The limiting pin 9 can be quickly unscrewed from the arc-shaped notch 8, realizing the quick disassembly and separation of the first connecting part 1 and the second connecting part 2. The reverse locking groove 10 and the limiting locking post 9 cooperate to form a locking mechanism, ensuring the stability and safety of the connection between the first connecting part 1 and the second connecting part 2. The outer wall of the pipe body 4 and the inner wall of the outer cylinder of the double-layer cylindrical body 6 are sealed together by the first sealing ring 11. The quick-connect and detachable connector structure can connect water pipes, gas pipes and oil pipes. That is, the first connecting part 1 and the second connecting part 2 of the connector structure are respectively connected to two pipe sections, and then the first connecting part 1 and the second connecting part 2 are assembled to enable the quick connection of the two pipe sections.

[0023] This connector structure features a standardized design with uniform dimensions and shape, facilitating quick connection and disconnection between different components. It can also connect to interfaces of water pumps, solenoid valves, etc., enabling rapid plug-and-play functionality for modular structures like these. Thus, when repairing or replacing specific modular structures, only the faulty module needs to be quickly removed from the system, and the new modular structure can be connected, eliminating the need for extensive disassembly and reinstallation of the entire system. Furthermore, visual labels or guides can be affixed to the pipes near the connector structure or to the modular structure itself, helping maintenance personnel quickly identify the direction from which to disassemble and assemble specific connections, ensuring rapid maintenance, reducing operational difficulty, and improving maintenance efficiency.

[0024] Based on the above embodiments, in a preferred embodiment, a second sealing ring 12 is fixedly embedded on the outer wall of the inner cylinder of the double-layer cylindrical body 6. When the tube 4 is inserted into the double-layer cylindrical body 6, the second sealing ring 12 fits tightly with the inner wall of the tube 4. The first sealing ring 11 and the second sealing ring 12 are located on the outer wall and inner wall of the tube 4, respectively. This further prevents leakage between the tube 4 and the double-layer cylindrical body 6, and further improves the sealing performance of the connector structure.

[0025] Based on the above embodiments, in a preferred embodiment, sealing gaskets are respectively placed on the first threaded connector 3 of the first connecting part 1 and the second threaded connector 5 of the second connecting part 2. The sealing gaskets improve the sealing performance between the first connecting part 1 and the second connecting part 2 and the pipeline. In addition, waterproof PTFE tape can be wrapped around the first threaded connector 3 and the second threaded connector 5 to further enhance the sealing effect at the connection.

[0026] Based on the above embodiments, in a preferred embodiment, the support spring 7 is a brass spring or a stainless steel spring. Both brass and stainless steel springs are corrosion-resistant springs, preventing the support spring 7 from rusting and corroding in liquid environments, and extending the service life of the connector structure.

[0027] Based on the above embodiments, in a preferred embodiment, a limiting ring 13 extends circumferentially on the outer wall of the inner cylinder of the double-layer cylindrical body 6 to prevent the support spring 7 from slipping. The thickness of the tube body 4 is less than the distance between the limiting ring 13 and the inner wall of the outer cylinder of the double-layer cylindrical body 6, so that the front end of the tube body 4 passes the limiting ring 13 and abuts against the support spring 7. The support spring 7 is always in a compressed state under the action of the limiting ring 13. When the front end of the tube body 4 passes the limiting ring 13 and abuts against the support spring 7, the support spring 7 is further compressed, thereby enabling the support spring 7 to exert an elastic force on the tube body 4 along the axial direction of the tube body 4. Specifically, the thickness of the tube body 4 can be uniformly less than the distance between the limiting ring 13 and the inner wall of the outer cylinder of the double-layer cylindrical body 6; or the front end of the tube body 4 can be provided with a circumferential notch to avoid the limiting ring 13. When the overall thickness of the tube body is relatively thin, a thicker first sealing ring 11 and second sealing ring 12 are required. If a circumferential notch is provided only at the front end of the tube body 4, the material used for the first sealing ring 11 and the second sealing ring 12 can be further reduced, provided that the front end of the tube body 4 can contact the support spring 7. That is, the sealing effect can be achieved by using a thinner first sealing ring 11 and the second sealing ring 12.

[0028] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
