[0034] See also Figure 2 , Figure 2This is an exploded view of a pipeline connection fixing structure. The pipeline connection fixing structure in this example includes a pipeline 1 and a connection component 2. The pipeline 1 is used to carry liquid flow, and the connection component 2 is used to connect and fix different pipelines 1.
[0035] Please also read Figure 3 , Figure 4 and Figure 5 , Figure 3 Fix the structural section view for pipe connections, Figure 4 for Figure 3 A magnified image of area A. Figure 5 It is a schematic diagram of the mounting hole structure, wherein a limiting protrusion 11 is provided at the end of the pipeline 1, and the limiting protrusion 11 is arranged around the outer wall of the pipeline 1; the connecting component 2 includes a first connecting member 21 and a second connecting member 22, the first connecting member 21 includes a sleeve 211, a sealing member 212 and a limiting member 213, the sleeve 211 is sleeved on the pipeline 1, the sleeve 211 is provided with a limiting shoulder 214 and a mounting hole 215, the limiting shoulder 214 is arranged around the inner wall of the sleeve 211, and abuts against one end of the limiting protrusion 11, the mounting hole 215 radially penetrates the sleeve 211, the limiting member 213 is installed in the mounting hole 215, and abuts against the other end of the limiting protrusion 11, the sealing member 212 is arranged between the limiting protrusion 11 and the limiting shoulder 214, and the second connecting member 22 is connected to the first connecting member 21.
[0036] Specifically, the connecting component 2 can connect two different pipelines 1, and the pipeline 1 can be used as a water injection nozzle or a water outlet nozzle. The outer wall of the pipeline 1 is ringed with a limiting protrusion 11, and the limiting protrusion 11 is fixed on the outer wall of the pipeline 1; the first connecting piece 21 and the second connecting piece 22 can both install the pipeline 1, and one connecting component 2 corresponds to connecting two pipelines 1. The sleeve 211 is sleeved on the pipeline 1 and connected with the pipeline 1. The limiting protrusion 11 is located in the sleeve 211, and the limiting protrusion 11 is located between the limiting shoulder 214 and the limiting piece 213. The limiting piece 213 is respectively in contact with the wall of the mounting hole 215 and the limiting protrusion 11. The second connecting piece 22 is used to connect another pipeline 1, and the sealing piece 212 is used to seal the sleeve 211 and the pipeline 1. The limiting piece 213 is an object that is set in the mounting hole 215 and can play a limiting role.
[0037] In specific application, the sealing member 212 is installed in the sleeve 211 so that the limiting shoulder 214 abuts against the sealing member 212, and the sleeve 211 of the first connecting member 21 is sleeved on the pipeline 1 so that the sealing member 212 abuts against the limiting protrusion 11 of the pipeline 1, and then the limiting member 213 is installed in the second mounting hole 215 so that the limiting member 213 abuts against the limiting protrusion 11, and the limiting member 213 cooperates with the limiting protrusion 11 and the surrounding wall of the mounting hole 215 of the sleeve 211 respectively to realize the sealing fixation of the connecting component 2 on the pipeline 1.
[0038] In this way, by setting a limiting protrusion 11 on the pipeline 1, setting a mounting hole 215 and a limiting shoulder 214 on the first connecting member 21, and using the mounting hole 215 to install the limiting member 213, the limiting member 213 cooperates with the limiting protrusion 11 and the limiting shoulder 214 to realize the assembly and fixation of the connecting component 2 on the pipeline 1. Compared with using a fixed bracket to seal the connection between the conversion head and the heater, the assembly method of the connecting component on the pipeline is changed, which not only simplifies the product structure and optimizes the internal space of the product, but also reduces the production cost.
[0039] Furthermore, the sleeve 211 includes a sealing section 2111 and a limiting section 2112, the sealing section 2111 is connected to the limiting section 2112, the first connecting member 21 is connected to the sealing section 2111, the limiting shoulder 214 and the sealing member 212 are both located in the sealing section 2111, the mounting hole 215 is provided in the limiting section 2112, and the inner diameter of the limiting section 2112 is larger than the inner diameter of the sealing section 2111.
[0040] Specifically, the sealing section 2111 is the portion of the first connecting member 21 facing the second connecting member 22, the limiting section 2112 is the portion of the first connecting member 21 facing away from the second connecting member 22, the sealing member 212 is located in the sealing section 2111, and is respectively sealed and connected to the inner wall surface of the sealing section 2111 and the outer wall surface of the sleeve 211, the sealing member 212 is located at the end of the limiting protrusion 11 facing away from the pipeline 1, and is respectively abutted against the limiting protrusion 11 and the limiting shoulder 214, the mounting hole 215 radially penetrates the limiting section 2112 of the sleeve 211, and the limiting protrusion 11 is located in the limiting section 2112.
[0041] In this way, by setting a sealing section 2111 with a smaller inner diameter, after the first connecting member 21 is sleeved on the pipeline 1, the limiting shoulder 214 of the sealing section 2111 abuts against the limiting protrusion 11, and the limiting section 2112 supports the limiting protrusion 11, so that the sealing section 2111 can have excellent sealing performance.
[0042] Furthermore, the sleeve 211 is provided with two mounting holes 215 , the two mounting holes 215 are arranged in a row at intervals, and the distances between different mounting holes 215 and the limiting protrusion 11 are equal.
[0043] In this way, the limiting member 213 disposed in the mounting hole 215 is more stable, less likely to shake, and is evenly stressed.
[0044] Please refer to the figure, which is a schematic diagram of the limit member structure. Further, the limit member 213 is "U"-shaped.
[0045] Specifically, the limiting member 213 is a U-shaped retaining spring, and two ends of the limiting member 213 can be respectively inserted into two mounting holes 215 on the same sleeve 211 .
[0046] Furthermore, the first connecting member 21 further includes a buffer member 216 , which is disposed in the sleeve 211 and between the limiting protrusion 11 and the sealing member 212 .
[0047] Specifically, the buffer member 216 is an annular buffer pad, which can extend the service life of the sealing member 212 .
[0048] Furthermore, the second connecting member 22 is provided with an anti-backward tooth 221 .
[0049] In this way, it is prevented that after another pipeline 1 is installed on the second connecting piece 22 , the pipeline 1 moves backward and falls off.
[0050] Furthermore, the first connecting member 21 and the second connecting member 22 are integrally formed.
[0051] Furthermore, the limiting protrusion 11 and the pipeline 1 are formed integrally.
[0052] Furthermore, the limiting member 213 is detachably disposed in the mounting hole 215 .
[0053] In this way, after the limiting member 213 is pulled out of the mounting hole 215 , the connecting assembly 2 and the pipeline 1 can be disassembled for easy maintenance.
[0054] In summary, by setting a limiting protrusion on the pipeline, setting a mounting hole and a limiting shoulder on the first connecting member, using the mounting hole to install the limiting member, and the limiting member cooperating with the limiting protrusion and the limiting shoulder, the assembly and fixation of the connecting component on the pipeline is realized. Compared with using a fixed bracket to seal the connection between the conversion head and the heater, the assembly method of the connecting component on the pipeline is changed, which not only simplifies the product structure and optimizes the internal space of the product, but also reduces the production cost.
[0055] The above is only the implementation mode of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
