Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment lines, in particular to a quick-jointed surface treatment line liquid supply pipe connection structure. Background Art

[0002] Surface treatment is a process method for artificially forming a surface layer on the surface of a base material with different mechanical, physical and chemical properties from the base material. Pipelines are usually required in the surface treatment line to supply and drain liquid to the surface treatment equipment. For example, Chinese Patent 202010576961.2 discloses an external pipeline quick-connect device for a surface treatment line. First, a surface treatment line body, a first pipeline, a second pipeline and a quick-connect assembly are set. The water outlet of the first pipeline is detachably connected to the water inlet of the second pipeline. The quick-connect assembly includes a first quick-connect component and a second quick-connect component. The first quick-connect component is mounted on the first pipeline, and the second quick-connect component is mounted on the second pipeline. The first quick-connect component is detachably connected to the second quick-connect component and forms a closed cavity inside. The water outlet of the first pipeline and the water inlet of the second pipeline are both located in the closed cavity.

[0003] The connection between the existing liquid inlet joint and the liquid supply pipe of the surface treatment equipment is relatively cumbersome. For surface treatment equipment with multiple liquid inlet joints and surface treatment lines with several surface treatment equipment, the liquid inlet joint and the liquid supply pipe cannot be quickly connected, which greatly affects the production efficiency of the surface treatment line. Utility Model Content

[0004] The utility model aims to provide a surface treatment line liquid supply pipe connection structure with quick connection, so as to solve the problem that the existing liquid inlet joint and the liquid supply pipe of the surface treatment equipment cannot be quickly connected.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a surface treatment line liquid supply pipe connection structure for quick docking, comprising:

[0006] Surface treatment equipment;

[0007] A liquid inlet joint, which is arranged on the side wall of the surface treatment equipment, and a connecting cavity is arranged at the end of the liquid inlet joint;

[0008] A liquid supply pipe, an end of which is provided with a plug-in pipe body, which is plugged into the connecting cavity, a plurality of circumferentially arranged positioning plates are provided on the outer peripheral surface of the plug-in pipe body, a slot corresponding to the position of the positioning plate is provided on the inner wall of the connecting cavity, a plurality of circumferentially arranged snap plates are provided on the outer peripheral surface of the liquid supply pipe, and a retaining ring corresponding to the position of the snap plate is provided on the liquid inlet joint.

[0009] As a further description of the above technical solution:

[0010] A guiding inclined surface is arranged on one side of the retaining ring facing the liquid supply pipe.

[0011] As a further description of the above technical solution:

[0012] A conical transition pipe body is arranged on the liquid inlet joint.

[0013] As a further description of the above technical solution:

[0014] The height of the positioning plate gradually decreases from the side away from the end surface of the plug-in tube body.

[0015] As a further description of the above technical solution:

[0016] The outer peripheral surface of the plug-in tube body is provided with three circumferentially arranged positioning plates.

[0017] As a further description of the above technical solution:

[0018] The outer peripheral surface of the liquid supply pipe is provided with three circumferentially arranged snap plates, and the positioning plates and the snap plates are arranged at intervals.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] 1. In the utility model, the surface treatment equipment is connected to the liquid supply pipe through the liquid inlet joint on the side wall to achieve liquid replenishment. When the liquid supply pipe is connected to the liquid inlet joint, the plug-in pipe body of the liquid supply pipe is inserted into the connection cavity at the end of the liquid inlet joint, and the positioning plate on the plug-in pipe body is aligned with the slot on the inner wall of the connection cavity. When the plug-in pipe body is plugged into place, the buckle plate is buckled with the retaining ring on the liquid inlet joint on the outside. The positioning plate prevents the liquid inlet joint and the liquid supply pipe from rotating relative to each other, and the buckle plate prevents the liquid supply pipe from detaching from the liquid inlet joint, effectively achieving a quick and firm connection between the liquid supply pipe and the liquid inlet joint.

[0021] 2. In the utility model, a guiding inclined surface is arranged on the side of the retaining ring facing the liquid supply pipe, so as to facilitate the opening of the snap plate, so that the snap plate and the retaining ring can be buckled more smoothly, thereby further realizing a quick connection.

[0022] 3. In the utility model, a conical transition pipe body is provided on the liquid inlet joint. The transition pipe body is provided on one side of the retaining ring, so that after the snap plate on the liquid supply pipe is engaged with the retaining ring, the end of the snap plate extends to the transition pipe body, and a large gap is formed between the end of the snap plate and the side wall surface of the transition pipe body, which facilitates the separation of the snap plate and the liquid inlet joint, thereby realizing quick disassembly.

[0030] Example 1

[0031] See also Figure 1-3 The utility model provides a technical solution: a quick-jointed surface treatment line liquid supply pipe connection structure, comprising:

[0032] Surface treatment equipment 1;

[0033] A liquid inlet connector 2 is disposed on a side wall of the surface treatment device 1, and a connecting cavity is disposed at the end of the liquid inlet connector 2;

[0034] The liquid supply pipe 3 has a plug-in pipe body 31 at its end, which is plugged into the connecting cavity. The outer peripheral surface of the plug-in pipe body 31 is provided with a plurality of circumferentially arranged positioning plates 311, and the inner wall of the connecting cavity is provided with a slot 21 whose position corresponds to the positioning plate 311. The outer peripheral surface of the liquid supply pipe 3 is provided with a plurality of circumferentially arranged snap plates 32, and the liquid inlet connector 2 is provided with a retaining ring 22 whose position corresponds to the snap plate 32.

[0035] A guiding inclined surface 221 is provided on the side of the retaining ring 22 facing the liquid supply pipe 3 to facilitate the opening of the snap plate 32 so that the snap plate 32 and the retaining ring 22 can be buckled more smoothly, thereby further realizing a quick connection.

[0036] The liquid inlet connector 2 is provided with a tapered transition tube body 23. The transition tube body 23 is arranged on one side of the retaining ring 22, so that after the snap plate 32 on the liquid supply pipe 3 is engaged with the retaining ring 22, the end of the snap plate 32 extends out to the transition tube body 23, and the gap between the end of the snap plate 32 and the side wall surface of the transition tube body 23 is large, which facilitates the separation of the snap plate 32 and the liquid inlet connector 2, and realizes quick disassembly.

[0037] The height of the positioning plate 311 gradually decreases from the side away from the end surface of the plug-in tube body 31 , so that the positioning plate 311 has a triangular structure, which facilitates the plug-in connection between the plug-in tube body 31 and the liquid inlet connector 2 .

[0038] The outer surface of the plug-in tube body 31 is provided with three circumferentially arranged positioning plates 311, and the outer surface of the liquid supply tube 3 is provided with three circumferentially arranged snap plates 32. The positioning plates 311 and the snap plates 32 are arranged at intervals, which effectively improves the stability of the connection between the liquid inlet connector 2 and the liquid supply tube 3.

[0039] Working principle: The surface treatment equipment 1 is connected to the liquid supply pipe 3 through the liquid inlet joint 2 on the side wall to achieve liquid replenishment. When the liquid supply pipe 3 is connected to the liquid inlet joint 2, the plug-in pipe body 31 of the liquid supply pipe 3 is inserted into the connection cavity at the end of the liquid inlet joint 2, and the positioning plate 311 on the plug-in pipe body 31 is aligned with the slot 21 on the inner wall of the connection cavity. When the plug-in pipe body 31 is plugged into place, the snap plate 32 is externally engaged with the retaining ring 22 on the liquid inlet joint 2. The positioning plate 311 prevents the liquid inlet joint 2 and the liquid supply pipe 3 from rotating relative to each other, and the snap plate 32 prevents the liquid supply pipe 3 from detaching from the liquid inlet joint 2, effectively achieving a quick and firm connection between the liquid supply pipe 3 and the liquid inlet joint 2.
