Description

Technical Field

[0001] This utility model relates to the field of silicon core tube technology, and in particular to a pressure-resistant silicon core tube that is easy to connect. Background Technology

[0002] With the rapid development of modern communication technology, silicon core tubes, as an important communication pipeline material, play a crucial role in the laying of optical cables, electrical cables and other lines. Due to their excellent physical properties, chemical stability and environmental adaptability, silicon core tubes have been widely used in long-distance communication, urban pipeline construction and other fields.

[0003] To meet the required length of silicon core tubes, two silicon core tubes need to be connected together. However, the existing silicon core tube connection methods still have some shortcomings in practical use:

[0004] When connecting silicon core tubes, connectors are commonly used. However, the process of connecting these connectors requires splicing them together, which is not only complicated but also makes it easy for components to be lost during the installation and splicing of the connectors. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, the connection process requires splicing various connectors, which is not only complicated, but also prone to component loss during the installation and splicing of various connectors. Therefore, this invention proposes a pressure-resistant silicon core tube that is easy to connect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressure-resistant silicon core tube that is easy to connect includes an outer tube, a first silicon core tube, and a second silicon core tube. The outer tube contains a first sleeve and a second sleeve. Both ends of the outer tube have threaded sections on their inner walls, and the two threaded sections have opposite thread directions. The outer tube is threaded onto the outer walls of the first sleeve and the second sleeve through the two threaded sections. The first sleeve and the second sleeve are fixedly connected to the opposite sides of each other with an installation port, and the opposite sides of the two installation ports are fitted to the two ends of the outer tube. The first sleeve and the second sleeve contain a common connecting tube, and both ends of the connecting tube have connectors. The opposite ends of the first silicon core tube and the second silicon core tube are respectively fitted onto the outer walls of the two connectors. The opposite ends of the two first sleeves each have a second inner ring on their inner walls, and the second inner ring clamps and engages with the connector.

[0008] In one possible design, the inner wall of the outer tube is provided with a movable groove, and the movable groove is located between two threaded sections. The ends of the first sleeve and the second sleeve that are close to each other are fixedly connected with abutment rings, and the two abutment rings slide in the movable groove. The sides of the two abutment rings that are far apart from each other respectively contact the inner wall of the side of the movable groove that is close to each other.

[0009] In one possible design, both the first sleeve and the second sleeve are provided with a first inner ring. The ends of the first sleeve and the second sleeve that are close to each other are fixedly connected with a limiting edge, and the sides of the two limiting edges that are far from each other respectively touch the sides of the two connectors that are close to each other. The first inner ring is provided with multiple sliding grooves, and the sliding grooves penetrate the adjacent limiting edges.

[0010] In one possible design, the outer wall of the connecting pipe is fixedly connected with multiple sliding strips, and the sliding strips slide in cooperation with adjacent sliding grooves.

[0011] In one possible design, the outer walls of both connectors are provided with a first cone shape, and the ends of the two connectors that are far apart from each other are provided with a second cone shape, the slope angle of the second cone shape being greater than the slope angle of the first cone shape.

[0012] In one possible design, the outer tube and the outer walls of the two mounting ports are both hexagonal, making it easy for a wrench to clamp and tighten them respectively.

[0013] In one possible design, a sealing ring is provided between the two abutment rings to increase the sealing between the two abutment rings.

[0014] In this application, by clamping the two mounting ports with a wrench and turning the outer tube, two reverse-designed threaded sections on the inner wall of the outer tube respectively engage with the reverse-designed threaded sections on the outer walls of the first and second sleeves. This drives the first and second sleeves away from each other, increasing the distance between the connector and the second inner ring. This causes the sides of the two limiting edges that are moving away from each other to abut against the sides of the two connectors that are moving closer together. This abutment against the connectors prevents the first sleeve from detaching from the outer wall of the connector. Simultaneously, as the first and second sleeves move away from each other within the outer tube, they slide within the moving groove via the abutment rings, preventing the first sleeve from falling out of the outer tube. At this point, the two ends of the two silicon core tubes are then separated... Do not slip it onto the two connectors. Twist the outer tube in the opposite direction. The two threaded sections of the inner diameter of the outer tube will engage with the threaded sections of the outer walls of the first and second sleeves, bringing the first and second sleeves closer together. During this process, the sliding groove inside the first sleeve slides under the constraint of the sliding strip, thereby clamping and fixing the silicon core tube on the connector with the second inner ring. The two abutting rings slide in the moving groove and fit together to achieve a seal between the two abutting rings. The two mounting ports fit together with one side of the outer tube as the first sleeve moves. The two ends of the outer tube are wrapped around the outer wall of the first sleeve, which can also improve the pressure resistance of the first sleeve and prevent the first sleeve from being torn.

[0015] Beneficial effects: In this utility model, the pressure-resistant silicon core tube that is easy to connect has an outer tube wrapped around the outer walls of the first and second sleeves, which can be limited by contact rings to prevent it from falling off. The connecting tube is limited to the first and second sleeves by limiting edges to prevent the connecting tube from falling out of the first and second sleeves. The layers of wrapping and limiting make the overall structure stronger and effectively prevent the falling off of related components.

[0016] In this utility model, the pressure-resistant silicon core tube that is easy to connect is connected to the silicon core tube through a connecting pipe and two connectors. At the same time, the sliding strip and the sliding groove cooperate, and the two threaded sections cooperate with the first sleeve and the second sleeve respectively. The layers of cooperation enhance the overall pressure resistance and effectively prevent the silicon core tube from being burst due to excessive pressure.

[0017] This invention has the advantages of convenient operation, strong pressure resistance, reliable sealing, strong adaptability, compact structure and easy maintenance, and can meet the usage needs of various complex environments. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figures 1 to 4 A pressure-resistant silicon core tube that is easy to connect is used in the field of silicon core tubes. It includes an outer tube 1, a first silicon core tube 2, and a second silicon core tube 3. The outer tube 1 is provided with a first sleeve 5 and a second sleeve 6. The inner walls of both ends of the outer tube 1 are provided with threaded sections 10, and the threads of the two threaded sections 10 are opposite in direction. The outer tube 1 is threaded onto the outer walls of the first sleeve 5 and the second sleeve 6 through the two threaded sections 10 respectively. The sides of the first sleeve 5 and the second sleeve 6 that are far apart from each other are fixedly connected with mounting ports 7, and the sides of the two mounting ports 7 that are close to each other are fitted with the two ends of the outer tube 1. The first sleeve 5 and the second sleeve 6 are provided with the same connecting tube 9. The two ends of the connecting tube 9 are provided with connectors 15, and the ends of the first silicon core tube 2 and the second silicon core tube 3 that are close to each other are respectively fitted onto the outer walls of the two connectors 15. The inner walls of the two ends of the first sleeve 5 that are far apart from each other are provided with second inner rings 14, and the second inner rings 14 are clamped and engaged with the connectors 15. Inside the outer tube 1, a first sleeve 5 and a second sleeve 6 are provided. These two sleeves are fixed by threaded sections 10 on the inner walls of both ends of the outer tube 1. It is worth noting that the thread directions of the two threaded sections 10 are opposite, which allows the outer tube 1 to be tightly fitted onto the outer walls of the first sleeve 5 and the second sleeve 6 by rotation. The first sleeve 5 and the second sleeve 6 are each fixedly connected to an installation port 7 on their opposite sides. When these two installation ports 7 are close to the ends of the outer tube 1, they can fit together, thus forming a stable connection structure. In addition, the first sleeve 5 and the second sleeve 6 are provided with a connecting tube 9 inside. Both ends of the connecting tube 9 are provided with connectors 15. The first silicon core tube 2 and the second silicon core tube 3 are respectively fitted onto the outer walls of the two connectors 15. In order to ensure the stability of the connection, the inner walls of the opposite ends of the first sleeve 5 and the second sleeve 6 are provided with second inner rings 14. These second inner rings 14 form a clamping fit with the connectors 15.

[0026] Reference Figure 4The inner wall of the outer tube 1 is provided with a movable groove 4, which is located between two threaded sections 10. The ends of the first sleeve 5 and the second sleeve 6 that are close to each other are fixedly connected with abutment rings 8, and both abutment rings 8 slide within the movable groove 4. The sides of the two abutment rings 8 that are far apart from each other respectively contact the inner walls of the movable groove 4 on the sides that are close to each other. The inner wall of the outer tube 1 is provided with a movable groove 4, which is located between two threaded sections 10. The ends of the first sleeve 5 and the second sleeve 6 that are close to each other are fixedly connected with abutment rings 8. These two abutment rings 8 move within the movable groove 4. When the two sleeves move away from each other, the two abutment rings 8 contact the inner walls of the two sides of the movable groove 4 respectively, thus forming a constraint and preventing the first sleeve 5 and the second sleeve 6 from falling out of the outer tube 1.

[0027] Reference Figure 4 Both the first sleeve 5 and the second sleeve 6 are provided with a first inner ring 11. A limiting edge 13 is fixedly connected to the adjacent ends of the first sleeve 5 and the second sleeve 6, and the opposite sides of the two limiting edges 13 respectively contact the adjacent sides of the two connectors 15. The first inner ring 11 is provided with multiple sliding grooves 12, which penetrate adjacent limiting edges 13. These two limiting edges 13 form additional contact surfaces with the connectors 15, increasing the stability of the connection. Furthermore, the first inner ring 11 also provides multiple sliding grooves 12 that penetrate adjacent limiting edges 13, providing space for the sliding of the connecting pipe 9.

[0028] Reference Figure 5 Multiple sliding strips 16 are fixedly connected to the outer wall of the connecting pipe 9, and the sliding strips 16 slide in engagement with the adjacent sliding grooves 12. The sliding strips 16 and the adjacent sliding grooves 12 form a sliding engagement, ensuring the stability of the connection between the connecting pipe 9 and the first sleeve 5 and the second sleeve 6.

[0029] Reference Figure 5 Both connectors 15 have a first cone shape on their outer walls, and a second cone shape at the ends of the two connectors 15 that are far apart from each other. The slope angle of the second cone is greater than that of the first cone. The cone design facilitates the insertion of the first silicon core tube 2 and the second silicon core tube 3 into the connector 15.

[0030] Reference Figure 5 The outer walls of the outer tube 1 and the two mounting ports 7 are all hexagonal, making it easy for a wrench to grip and tighten them. The shape of the outer walls of the outer tube 1 and the two mounting ports 7 is explained; they are all designed in a hexagonal shape, which makes it easier for a wrench to grip and tighten them, thus facilitating the entire process of installing and removing the silicon core tube.

[0031] Example 2: Reference Figure 4An improvement upon Embodiment 1 is made by providing a sealing ring between each of the two contact rings 8, thereby increasing the sealing performance between them. The sealing ring ensures the seal after the two contact rings 8 come into contact.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
