Description

Technical Field

[0001] This utility model relates to the field of spring tube technology, specifically a spring tube and its assembly. Background Technology

[0002] PTFE spring tubes / spiral tubes are flexible tubes made of thin-walled polytetrafluoroethylene (PTFE) tubing, which are rotated at a certain speed in a special hot mold to form a spiral corrugated shape or a spring shape. They are mainly used for flexible connections, misaligned connections, serpentine pipelines, and inlet and outlet pipes of vibrating components such as pumps and motors in equipment that is resistant to strong corrosion and high temperature.

[0003] In traditional technology, when the spring tube is used, the wires at the top and bottom are located at the edge. When connected to the fittings, the fittings are located in the middle. Due to the structural influence, the spring tube is very easy to bend, which affects the flow of the medium.

[0004] Furthermore, the common assembly structure of spring tubes on the market is as follows: after the spring tube is glued, it is installed into the assembly and then positioned by a metal retaining ring. The assembly is complicated and difficult. Manual operation is prone to errors, such as misalignment of the sealing ring. The retaining ring can puncture the spring tube (which is only 0.5 mm thick) during assembly and transportation. At the same time, wear on the sharp-angled hardware on the edge of the assembly during transportation can easily cause the spring tube to break and leak oil.

[0005] Therefore, this utility model provides a spring tube and its assembly to solve the above problems. Utility Model Content

[0031] 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.

[0032] Example 1:

[0033] Please see Figure 1-2 A spring tube, comprising:

[0034] The spring tube body 1 has both its top and bottom ends bent toward the middle, and both the top and bottom ends of the spring tube body 1 are in a vertical state.

[0035] Quick-release block 2 is fixedly connected to the top end of spring tube body 1. A plug block 3 is fixedly connected to the top end of quick-release block 2, and a quick-release component is provided on the outer side of plug block 3.

[0036] More specifically, through the overall structural characteristics of the spring tube body 1, the sharp corners during bending are effectively avoided, the resistance to the flow of medium inside the spring tube body 1 is reduced, making the flow of medium smoother, and the outlet direction of the spring tube body 1 is located in the middle, avoiding bending during the assembly process.

[0037] In this embodiment, both the quick-release block 2 and the insert block 3 are cylindrical;

[0038] In this embodiment, the quick-release component is a positioning buckle 4, which is wedge-shaped, and there are no fewer than three positioning buckles 4;

[0039] More specifically, the positioning buckle 4 is made of elastic material. Through the shape and material properties of the positioning buckle 4, the positioning buckle 4 can undergo a certain deformation when it is compressed, and can return to its original shape when it is not compressed.

[0040] In this embodiment, the insert block 3 and the positioning buckle 4 are injection molded;

[0041] More specifically, the injection molding method enables automated and high-speed production of insert 3 and positioning buckle 4, and can ensure the dimensional accuracy and quality of insert 3 and positioning buckle 4 in the same batch, while effectively controlling the production cost of insert 3 and positioning buckle 4.

[0042] In other embodiments, the quick-release component may also be an externally threaded sleeve 12, which is fixedly connected to the outside of the quick-release block 2;

[0043] Example 2:

[0044] Please see Figure 3-4 This embodiment provides a spring tube assembly based on Embodiment 1, comprising:

[0045] Assembly cylinder 5, with insertion holes 6 in the middle of the top and bottom ends of assembly cylinder 5, and mating parts are provided inside the insertion holes 6, which are used to mate with the quick-release parts to position the quick-release block 2.

[0046] In this embodiment, the mating part is a locking groove 7, which is opened at the end of the insertion hole 6 and is used to engage with the positioning buckle 4 to abut against the quick-mount block 2;

[0047] In other embodiments, the mating component may also be an internally threaded sleeve 13, which is fixedly connected to the inside of the insertion hole 6, and the externally threaded sleeve 12 is connected to the internally threaded sleeve 13.

[0048] Please refer to Figure 7 Through the cooperation of the internal threaded sleeve 13 and the external threaded sleeve 12, the external threaded sleeve 12 can also be screwed into the internal threaded sleeve 13 to achieve the positioning of the quick-release block 2;

[0049] In this embodiment, both the insertion hole 6 and the locking groove 7 are circular, and the diameter of the insertion hole 6 is smaller than the diameter of the locking groove 7.

[0050] More specifically, the shape characteristics of the socket 6 and the locking groove 7 provide space for the assembly of the quick-release block 2 and the insert block 3, ensuring the stability of the spring tube body 1 in application.

[0051] In this embodiment, the top and bottom ends of the assembly cylinder 5 are parallel to the quick-release block 2 to ensure the installation accuracy of the insert block 3;

[0052] In this embodiment, the outer side of the assembly cylinder 5 is provided with multiple threaded sections 9, and multiple notches 10 are provided at the threaded sections 9;

[0053] More specifically, by setting the threaded section 9, the assembly cylinder 5 can be assembled with external threaded connectors by means of the threaded section 9, thereby ensuring the ease of installation of the assembly cylinder 5.

[0054] In this embodiment, a sealing ring 8 is provided inside the locking groove 7;

[0055] More specifically, by setting the sealing ring 8, after the insert 3 is fully inserted into the locking groove 7, the end of the insert 3 away from the quick-release block 2 will contact the sealing ring 8, pre-pressing the sealing ring 8 to mechanically seal the gap between the insert 3 and the locking groove 7.

[0056] Furthermore, in order to ensure the sealing effect of the sealing ring 8, the material of the sealing ring 8 can be rubber;

[0057] In this embodiment, a flow channel 11 is provided between the two locking slots 7;

[0058] More specifically, the flow channel 11 allows for the space between the two locking slots 7 to allow for the flow of the medium, thereby enabling the transfer of the medium.

[0059] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0060] Please refer to Figures 5-6 One specific application of the above two embodiments is as follows: First, the insert block 3 is aligned with the socket 6, and the insert block 3 is inserted into the socket 6. After the insert block 3 is inserted into the socket 6, the positioning buckle 4 will contact the inner wall of the socket 6. As the insert block 3 is continuously inserted, the positioning buckle 4 can be squeezed by the inner wall of the socket 6, causing the positioning buckle 4 to deform until the quick-release block 2 contacts the assembly cylinder 5. At this time, the positioning buckle 4 reaches the inside of the locking groove 7. At the same time, since the positioning buckle 4 is no longer squeezed by the socket 6, the insertion block 3 can be restricted inside the locking groove 7 by means of the restoration of the positioning buckle 4. In this way, the quick assembly between the spring tube body 1 and the assembly cylinder 5 can be achieved without direct contact between the spring tube body 1 and the assembly cylinder 5. During transportation, the medium will not leak due to the contact wear between the assembly cylinder 5 and the spring tube body 1.
