Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a solar tube connector structure. Background Technology

[0002] In solar water heating systems, solar water pipes are a key component for hot water delivery. To ensure smooth hot water delivery to different areas, two solar water pipes often need to be spliced ​​together. Solar pipes are divided into straight pipes and curved pipes. Curved pipes can flexibly adapt to complex installation environments and achieve smooth connections between pipes in different directions. When connecting curved pipes with existing solar pipe joints, the water flow inside the pipe, under pressure, passes through the bend of the curved pipe. Due to the sudden change in the flow cross-section, the direction of water flow changes drastically, generating a continuous impact force on the inner wall of the bend. This impact force dynamically changes with water flow velocity, pressure fluctuations, and medium temperature variations, thus causing the entire curved pipe to vibrate. This vibration is transmitted through the pipe body to the connectors at both ends, causing the connectors to loosen at the pipe interface. Therefore, this utility model proposes a solar pipe joint structure. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background technology where, when connecting arc-shaped pipes, the water flowing through the bend of the arc-shaped pipe under pressure experiences a sudden change in the direction of water flow due to the sudden change in the flow cross-section. This causes a continuous impact force on the inner wall of the bend, and the impact force dynamically changes with the water flow velocity, pressure fluctuations, and medium temperature changes. This results in the overall vibration of the arc-shaped pipe, which is transmitted through the pipe body to the connectors at both ends, causing the connectors to loosen at the pipe interface. The invention proposes a solar tube connector structure.

[0004] The technical solution of this utility model is as follows: a solar tube connector structure, including a pipe, and further including: limiting collars fixedly disposed at both ends of the pipe, with connectors movably sleeved at both ends of the pipe; a fixing collar fixedly sleeved on the outer wall of the pipe, with a positioning component slidably disposed on the fixing collar for limiting the connectors.

[0005] Optionally, the positioning component includes a movable collar that is movably fitted onto the outer wall of the pipe. Multiple guide rods are fixedly provided on one side of the movable collar. The guide rods are slidably connected to the fixed collar. A limit ring is fixedly connected to one end of the guide rod. A spring is fitted onto the outer wall of the movable collar. One end of the spring is fixedly connected to the fixed collar, and the other end of the spring is fixedly connected to the limit ring.

[0006] Optionally, the positioning component further includes a socket ring rotatably arranged inside the limiting ring. A threaded rod is fixedly arranged on the outer wall of the socket ring. The threaded rod penetrates through the limiting ring and is threadedly sleeved with a limiting nut. A plurality of insertion blocks are fixedly arranged on one side of the socket ring.

[0007] Optionally, a groove is formed on one side of the limiting sleeve ring, and a sealing ring is arranged inside the groove.

[0008] Optionally, a plurality of slots are formed on one side of the connecting head.

[0009] Optionally, a plurality of guiding grooves are formed on the outer wall of the fixed sleeve ring, and the guiding grooves are movably sleeved with guiding rods.

[0010] Optionally, a sliding groove is formed on the outer wall of the limiting ring, and the sliding groove is slidably connected with the threaded rod.

[0011] Optionally, the guiding grooves and the guiding rods are arranged in a "convex" shape structure.

[0012] In summary, the present application includes at least the following beneficial technical effects:

[0013] Through the cooperation of the movable sleeve ring, the wire guiding rod, the limiting ring, the spring, the socket ring, the threaded rod, the limiting nut and the insertion blocks in the positioning component and the slots formed on the connecting head, the present utility model can realize the limiting and fixing of the connecting head. The elastic force of the spring continuously pushes the limiting ring, so that the insertion blocks are tightly embedded in the slots. At the same time, the cooperation of the threaded rod and the limiting nut can be further locked, effectively offsetting the acting force transmitted from the vibration of the arc-shaped pipeline to the connecting head, and preventing the loosening of the connection between the connecting head and the pipeline interface.

[0014] Furthermore, by arranging a sliding groove on the outer wall of the limiting ring, the sliding groove can guide the threaded rod, so that the threaded rod drives the insertion blocks on the socket ring to move, thereby enabling the insertion blocks to be stably inserted into the slots, improving the limiting of the connecting head and enhancing the stability of the connection.

[0028] Example

[0029] As shown Figures 1 to 3 in the figure, a solar pipe joint structure proposed by the utility model includes a pipe 1, and the pipe 1 is an arc-shaped pipe. It further includes: limit collar rings 2 are fixedly arranged at both ends of the pipe 1 by welding. A groove 6 is formed on one side of the limit collar ring 2, and a sealing ring 7 is arranged inside the groove 6, which can increase the sealing performance between the limit collar ring 2 and the connector 3 and avoid leakage. Connectors 3 are movably sleeved at both ends of the pipe 1, and are threadedly and sealedly connected to the solar pipe through the connectors 3. A plurality of slots 8 are formed on one side of the connector 3 for cooperating with the insertion blocks 58 to limit the connector 3. Fixed collar rings 4 are fixedly sleeved on the outer walls of both ends of the pipe 1.

[0030] As shown Figures 2 to 3 in the figure, a positioning component 5 for limiting the connector 3 is slidably arranged on the fixed collar ring 4. The positioning component 5 includes a movable collar ring 51 movably sleeved on the outer wall of the pipe 1. A plurality of guide rods 52 are fixedly arranged on one side of the movable collar ring 51, which can drive the plurality of guide rods 52 to move simultaneously. The guide rods 52 are slidably connected to the fixed collar ring 4 to ensure that the guide rods 52 move more stably. One end of the guide rod 52 is fixedly connected to a limit ring 53, which can drive the limit ring 53 to move through the guide rod 52. A spring 54 is sleeved on the outer wall of the movable collar ring 51. One end of the spring 54 is fixedly connected to the fixed collar ring 4, and the other end of the spring 54 is fixedly connected to the limit ring 53. A thrust is provided to the limit ring 53 through the elastic force of the spring 54 itself to prevent the limit ring 53 from moving due to vibration.

[0031] Secondly, the positioning component 5 further includes a socket ring 55 rotatably arranged inside the limit ring 53. A threaded rod 56 is fixedly arranged on the outer wall of the socket ring 55, which can drive the socket ring 55 to rotate inside the limit ring 53 through the threaded rod 56. A chute 10 is formed on the outer wall of the limit ring 53, and the chute 10 is slidably connected to the threaded rod 56 to ensure the stability of the movement of the socket ring 55. The threaded rod 56 penetrates through the limit ring 53 and extends to be threadedly sleeved with a limit nut 57, and the socket ring 55 can be limited through the limit nut 57. A plurality of insertion blocks 58 are fixedly arranged on one side of the socket ring 55, which can drive the insertion blocks 58 to move by the socket ring 55, so that the insertion blocks 58 are inserted into the slots 8 to limit the connector 3.

[0032] Furthermore, a plurality of guide grooves 9 are formed on the outer wall of the fixed collar ring 4, and the guide grooves 9 are movably sleeved with the guide rods 52. The guide grooves 9 and the guide rods 52 are arranged in a "convex" shape structure, which can guide the guide rods 52 and make the limit ring 5 stable in movement.

[0033] The working principle of this embodiment is as follows: When installing the solar pipe, first sleeve the connector 3 with the solar pipe and rotate the connector 3 to threadedly connect the connector 3 with the solar pipe. At the same time, the connector 3 will tightly press the sealing ring 7, so as to ensure the sealed connection between the connector 3 and the solar pipe.

[0034] Then, the spring 54 pushes the limiting ring 53 to one side of the connector 3 by its own elastic force. The limiting ring 53 drives the guide rod 52 to slide inside the guide groove 9, ensuring the stability of the movement of the limiting ring 53. At the same time, the limiting ring 53 drives the sleeve ring 55 to move towards the connector 3, and the sleeve ring 55 drives the insert block 58 to fit tightly against the connector 3.

[0035] Manually rotate the threaded rod 56. The threaded rod 56 drives the sleeve ring 55 to rotate inside the limiting ring 53. The sleeve ring 55 drives the insert block 58 to move, so that the insert block 58 can be inserted into the slot 8. Then rotate the limiting nut 57 on the threaded rod 56 to make the limiting nut 57 fit tightly against the limiting ring 53, thereby limiting the threaded rod 56, preventing the sleeve ring 55 from moving, and preventing the connector 3 from loosening at the interface with the pipe 1.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
