[0001] The utility model relates to the field of joint devices, in particular to a quick-connect joint for a heat dissipation coil. Background Art

[0002] The quick-connect fitting for radiator coils is a pipe connection component that is easy to install and maintain. It allows the radiator coil to be quickly connected to other piping systems (such as cooling systems). The quick-connect fitting does not require the use of traditional welding or threaded connection methods and can quickly connect and disconnect pipes, thereby simplifying the installation process and reducing downtime. It is especially useful in situations where frequent replacement or maintenance is required.

[0003] The design of traditional connectors may be complex, making installation and maintenance difficult. The complex structure means higher production costs. Traditional connectors may require multi-step operation, which is time-consuming and labor-intensive. Traditional connectors may become loose during long-term use, affecting the reliability of the connection.

[0004] Therefore, those skilled in the art provide a quick-connect connector for a heat dissipation coil to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the prior art and to propose a quick-connect joint for a heat dissipation coil. When the operator connects the first pipe fitting and the second pipe fitting together, the two guide rods will slide downward on the inner wall of the connecting plate, and the third spring will stretch upward and slide the clamping ring upward. At this time, the protrusion in the mounting hole will slide into the first clamping groove, and the first pipe fitting and the second pipe fitting can be quickly clamped.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The quick-connect joint for a heat dissipation coil comprises a connecting mechanism, wherein the connecting mechanism comprises a clamping ring, a first pipe fitting and a second pipe fitting, the upper portion of the inner wall of the clamping ring is provided with a first clamping groove, the lower portion of the inner wall of the clamping ring is provided with a second clamping groove, the middle portion of the inner wall of the first pipe fitting is clamped and matched with a first connecting ring, the lower end of the first connecting ring is fixedly connected to a first connecting plate, the inner wall of the middle first connecting plate is slidably connected to a first guide rod, the lower end of the first guide rod is fixedly connected to a first fixing block, and the outer wall of the first guide rod is sleeved with a first elastic A spring, a plurality of mounting holes are opened on the upper part of the outer wall of the second tube, and the inner walls of the mounting holes are slidably connected with protrusions, the middle part of the outer wall of the second tube is fixedly connected with a fixing plate, the upper end of the fixing plate is fixedly connected with a second spring, the lower part of the inner wall of the second tube is snap-fitted with a second connecting ring, the upper end of the second connecting ring is fixedly connected with the second connecting plate, the inner wall of the second connecting plate in the middle is slidably connected with a second guide rod, the upper end of the second guide rod is fixedly connected with the second fixing block, and the outer wall of the second guide rod is sleeved with a third spring;

[0008] Through the above technical solution, the operator connects the first pipe fitting and the second pipe fitting together. When the first fixing block and the second fixing block are fitted together, the two guide rods will slide downward on the inner wall of the connecting plate, and at this time, they will squeeze the first spring and the second spring downward. At this time, the third spring will stretch upward and slide the clamping ring upward. At this time, the protrusion in the mounting hole will slide into the first clamping groove, and the first pipe fitting and the second pipe fitting can be quickly clamped. It has the advantages of simple structure, low production cost and easy connection operation. Moreover, the more the pipe fitting is pushed outward, the tighter the clamping ring can bite by pressing, which has the advantages of firm and stable connection.

[0009] Furthermore, the upper end of the first spring is fixedly connected to the lower end of the first connecting plate, and the lower end of the first spring is fixedly connected to the upper end of the first fixing block;

[0010] Through the above technical solution, the first spring plays a buffering role during the connection process, which can reduce the impact caused by the connection or disconnection operation and protect the connector from damage.

[0011] Furthermore, the upper end of the third spring is fixedly connected to the lower end of the second connecting ring, and the lower end of the third spring is fixedly connected to the upper end of the second connecting plate;

[0012] Through the above technical solution, the elastic connection provided by the third spring can absorb a certain amount of external force impact, reduce wear and damage caused by direct rigid contact, and increase the service life of the joint.

[0013] Furthermore, the outer walls of the protrusions slide with the inner walls of the first engaging grooves;

[0014] Through the above technical solution, the protrusion is located in the mounting hole. When the quick-connect connector is operated, the protrusion can slide on the inner wall of the first snap-on groove. This sliding mechanism allows the connector to be accurately aligned and locked during connection and disconnection.

[0015] Furthermore, the outer wall of the second spring slides with the inner wall of the second engaging groove;

[0016] Through the above technical solution, the second spring plays a buffering role during the connection process, which can reduce the wear and impact caused by direct metal-to-metal contact and evenly distribute the connection pressure.

[0017] Furthermore, the first pipe and the second pipe are snap-fitted together via a snap-fit ​​ring;

[0018] Through the above technical solution, the clamping ring is a key component in the quick connector, which is responsible for firmly connecting the first pipe fitting and the second pipe fitting together. The clamping ring is usually designed with a special shape or structure to match the outer surface or specific part of the pipe fitting.

[0019] Furthermore, a first sealing ring is snap-fitted to the middle portion of the outer wall of the first fixing block, and a second sealing ring is snap-fitted to the middle portion of the outer wall of the second fixing block;

[0020] With the above technical solution, the main function of the first sealing ring and the second sealing ring is to provide a seal to prevent fluid leakage at the pipe connection, which is crucial for heat dissipation coils or other fluid transmission systems.

[0021] The utility model has the following beneficial effects:

[0022] 1. The quick-connect joint for the heat dissipation coil proposed by the present invention is that the operator connects the first pipe fitting and the second pipe fitting together. When the first fixing block and the second fixing block are in contact with each other, the two guide rods will slide downward on the inner wall of the connecting plate, and at this time, they will squeeze the first spring and the second spring downward. At this time, the third spring will stretch upward and slide the clamping ring upward. At this time, the protrusion in the mounting hole will slide into the first clamping groove, and the first pipe fitting and the second pipe fitting can be quickly clamped together. The utility model has the advantages of simple structure, low production cost and easy connection operation. Moreover, the more the pipe fitting is pushed outward, the tighter the clamping ring can bite by pressing, which has the advantages of firm and stable connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a specific implementation method provided by the utility model:

[0032] A quick-connect connector for a heat dissipation coil comprises a connecting mechanism 1, which comprises a clamping ring 101, a first pipe 104 and a second pipe 113. A first clamping groove 102 is provided on the upper portion of the inner wall of the clamping ring 101, a second clamping groove 103 is provided on the lower portion of the inner wall of the clamping ring 101, a first connecting ring 105 is clamped in the middle portion of the inner wall of the first pipe 104, the lower end of the first connecting ring 105 is fixedly connected to a first connecting plate 106, the inner wall of the middle first connecting plate 106 is slidably connected to a first guide rod 107, the lower end of the first guide rod 107 is fixedly connected to a first fixing block 108, and the outer wall of the first guide rod 107 is sleeved with a first spring 1 10. A plurality of mounting holes 111 are formed on the upper portion of the outer wall of the second tube 113. The inner walls of the mounting holes 111 are slidably connected to protrusions 112. A fixing plate 121 is fixedly connected to the middle portion of the outer wall of the second tube 113. The upper end of the fixing plate 121 is fixedly connected to a second spring 114. A second connecting ring 120 is snap-fitted to the lower portion of the inner wall of the second tube 113. The upper end of the second connecting ring 120 is fixedly connected to a second connecting plate 118. A second guide rod 116 is slidably connected to the inner wall of the middle second connecting plate 118. The upper end of the second guide rod 116 is fixedly connected to a second fixing block 115. The outer wall of the second guide rod 116 is sleeved with a third spring 117.

[0033] The operator connects the first pipe fitting 104 and the second pipe fitting 113 together. When the first fixing block 108 and the second fixing block 115 are fitted together, the two guide rods will slide downward on the inner wall of the connecting plate, and at this time, the first spring 110 and the second spring 114 will be squeezed downward. At this time, the third spring 117 will stretch upward and slide the clamping ring 101 upward. At this time, the protrusion 112 in the mounting hole 111 will slide into the first clamping groove 102, and the first pipe fitting 104 and the second pipe fitting 113 can be quickly clamped together. It has the advantages of simple structure, low production cost and easy connection operation. Moreover, the more the pipe fitting is withdrawn outward, the tighter the clamping ring 101 can be bitten by pressure, which has the advantages of firm and stable connection.

[0034] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The upper end of the first spring 110 is fixedly connected to the lower end of the first connecting plate 106, and the lower end of the first spring 110 is fixedly connected to the upper end of the first fixing block 108. The first spring 110 plays a buffering role during the connection process, which can reduce the impact caused by the connection or disconnection operation and protect the connector from damage. The upper end of the third spring 117 is fixedly connected to the lower end of the second connecting ring 120, and the lower end of the third spring 117 is fixedly connected to the upper end of the second connecting plate 118. The elastic connection provided by the third spring 117 can absorb a certain amount of external force impact, reduce the wear and damage caused by direct rigid contact, and improve the service life of the connector. The outer walls of the protrusion 112 slide with the inner wall of the first card groove 102, and the protrusion 112 is located in the mounting hole 111. When the quick connect connector is operated, the protrusion 112 can slide on the inner wall of the first card groove 102. This sliding mechanism allows the connector to be connected and disconnected. Precise alignment and locking are achieved. The outer wall of the second spring 114 slides against the inner wall of the second engaging groove 103. The second spring 114 acts as a buffer during the connection process, reducing wear and impact caused by direct metal-to-metal contact while evenly distributing the connection pressure. The first pipe 104 and the second pipe 113 are connected by a snap ring 101. The snap ring 101 is a key component in a quick connector, responsible for securely connecting the first and second pipes 104, 113. The snap ring 101 is typically designed with a special shape or structure to mate with the outer surface or specific portion of the pipe. A first sealing ring 109 is snap-fitted to the middle of the outer wall of the first fixing block 108, and a second sealing ring 119 is snap-fitted to the middle of the outer wall of the second fixing block 115. The primary function of the first and second sealing rings 109, 119 is to provide a seal to prevent fluid leakage at the pipe connection. This is crucial for heat dissipation coils or other fluid transmission systems.

[0035] Working principle: The operator connects the first pipe fitting 104 and the second pipe fitting 113 together. When the first fixing block 108 and the second fixing block 115 are fitted together, the two guide rods will slide downward on the inner wall of the connecting plate, and at this time, the first spring 110 and the second spring 114 will be squeezed downward. At this time, the third spring 117 will stretch upward and slide the clamping ring 101 upward. At this time, the protrusion 112 in the mounting hole 111 will slide into the first clamping groove 102, and the first pipe fitting 104 and the second pipe fitting 113 can be quickly clamped. It has the advantages of simple structure, low production cost and easy connection operation, and the more the pipe fitting is withdrawn outward, the tighter the clamping ring 101 can be bitten by pressure, which has the advantages of firm and stable connection.
