Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to an automatic milking pipeline connection structure that is easy to disassemble and clean. Background Technology

[0002] Milking pipelines are closed tubular systems used in modern dairy farming to efficiently and hygienically transport milk collected by milking equipment (such as milking cup sets and milk collectors) to milk storage equipment (milk storage tanks and refrigeration tanks). Automatic milking pipeline connection structures are detachable sealing components used for connecting pipelines in automatic milking systems.

[0003] Traditional sealing methods are limited and prone to leakage due to loose connections. They lack stability and are difficult to adapt to the high-frequency disassembly, thorough cleaning, and safe transportation requirements of automated milking systems, thus affecting production efficiency and dairy product quality. Therefore, we propose an automated milking pipeline connection structure that is easy to disassemble and clean. Utility Model Content

[0004] The purpose of this invention is to provide an automatic milking pipe connection structure that is easy to disassemble and clean, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic milking pipe connection structure that is easy to disassemble and clean, comprising two pipe bodies and a T-shaped connecting pipe, wherein both ends of the pipe body are provided with switch valves, and the connecting ends of the pipe body are fixedly connected with external threaded connecting rings, and the pipe body is provided with branch valves;

[0006] The outer wall of the external threaded connecting ring is threaded with an internal threaded ring cylinder. One end of the internal threaded ring cylinder is fixedly connected to an internal threaded connecting cylinder. Both ends of the T-shaped connecting pipe are fixedly connected to threaded sleeves. Several slits are opened through the connecting port of each threaded sleeve. The external thread of the threaded sleeve is threadedly connected to the internal threaded connecting cylinder.

[0007] Preferably, several sealing rings are fitted onto the outer walls of both ends of the T-shaped connecting pipe, and the sealing rings are all interference fit with the inner wall of the pipe body.

[0008] Preferably, the threaded sleeve is made of polypropylene, polyethylene, or polytetrafluoroethylene.

[0009] Preferably, the inner wall of the threaded sleeve is tapered.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by using the threaded engagement of the external threaded connecting ring and the internal threaded ring cylinder, and the internal threaded connecting cylinder, along with the elastic threaded sleeve with a slit (made of polypropylene or other materials), the assembly and disassembly can be completed by rotation without the need for complicated tools, which greatly improves the efficiency of assembly and disassembly, facilitates thorough cleaning of each component after disassembly, eliminates the risk of milk residue residue, and the conical inner cylinder wall is squeezed and pressed to fit the pipe as it is screwed, with the sealing ring providing interference sealing, providing double protection against leakage and enhancing the stability of the connection.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution:

[0019] Example 1: An automatic milking pipe connection structure that is easy to disassemble and clean includes two pipe bodies 1 and a T-shaped connecting pipe 2. Both ends of the pipe body 1 are equipped with switch valves 11. The connecting ends of the pipe body 1 are fixedly connected with external threaded connecting rings 12. The pipe body 1 is equipped with a branch valve 21. Both ends of the T-shaped connecting pipe 2 are fitted with several sealing rings 22 on the outer wall. The sealing rings 22 are all interference fit with the inner wall of the pipe body 1.

[0020] In use, first close the switch valves 11 at both ends of the pipe body 1 and the branch valves 21 on the T-shaped connecting pipe 2. Align the two ends of the T-shaped connecting pipe 2 with the connection ends of the two pipe bodies 1 respectively. Since the sealing rings 22 fitted on the outer walls of the two ends of the T-shaped connecting pipe 2 are interference fit with the inner walls of the pipe body 1, directly insert the T-shaped connecting pipe 2 into the pipe body 1, and achieve a sealed connection through the sealing rings 22. After the connection is completed, open the switch valves 11, and fluid can flow between the two pipe bodies 1 and the T-shaped connecting pipe 2 through the T-shaped connecting pipe 2. When disassembly and cleaning are required, close the switch valves 11, directly pull out the T-shaped connecting pipe 2, and clean the inner wall of the pipe body 1, the outer wall of the T-shaped connecting pipe 2, and the sealing rings 22. After cleaning, reassemble as described above.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: an external threaded connecting ring 12 with an internal threaded ring cylinder 13 threaded to its outer wall; an internal threaded connecting cylinder 14 fixedly connected to one end of the internal threaded ring cylinder 13; threaded sleeves 23 fixedly connected to both ends of the T-shaped connecting pipe 2; several slits 201 penetrating through the connecting port of the threaded sleeves 23; the external thread of the threaded sleeves 23 threadedly connected to the internal threaded connecting cylinder 14; the threaded sleeves 23 are made of polypropylene, polyethylene, or polytetrafluoroethylene; the inner wall of the threaded sleeves 23 has a conical cross-section; and the external thread of the external threaded connecting ring 12 is close to its end.

[0022] In use, first close the valves 11 at both ends of the pipe body 1, and align the threaded sleeve 23 with the external threaded connecting ring 12 of the pipe body 1. Rotate the internal threaded ring 13 so that it moves forward along the external thread of the external threaded connecting ring 12 (near the end position), while driving the internal threaded connecting sleeve 14 to engage with the threaded sleeve 23.

[0023] During the tightening process, the internal threaded connecting sleeve 14 continuously squeezes the threaded sleeve 23 (made of elastic materials such as polypropylene) with the slit 201. Because the inner wall of the threaded sleeve 23 is conical, its inner wall will tightly fit the outer wall of the T-shaped connecting pipe 2 during the squeeze. At the same time, the outer side contracts through the slit 201 to further press the sealing ring 22 at the interface of the pipe body 1 (enhancing the sealing effect).

[0024] After connection, open valve 11. Fluid can be diverted or merged through T-connector 2. Diversion valve 21 can regulate the flow rate. For disassembly, rotate the internal threaded ring 13 in the opposite direction to separate the internal threaded connecting sleeve 14 from the threaded sleeve 23. Then, remove T-connector 2 and thoroughly clean all components. After cleaning, tighten it again according to the above steps for reuse.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
