Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0021] Example 1: Please refer to Figures 1 to 2 A double-walled tube support assembly includes an outer wall tube 1, an inner wall tube 2, a snap-fit ​​assembly 3, a telescopic assembly 4, a securing assembly 5, and an auxiliary assembly 6; the inner wall tube 2 is nested inside the outer wall tube 1, and the snap-fit ​​assembly 3 is fixedly installed on the outside of the inner wall tube 2; the telescopic assembly 4 is installed on the snap-fit ​​assembly 3, the securing assembly 5 is installed on the telescopic assembly 4, and the auxiliary assembly 6 is installed on the snap-fit ​​assembly 3.

[0022] The first snap-fit ​​ring 301 in the snap-fit ​​assembly 3 is adapted to snap-fit ​​on the outside of the inner wall tube 2. Sliding rods 302 are evenly fixed on the first snap-fit ​​ring 301, and a second snap-fit ​​ring 303 is fixedly connected to the bottom end of the sliding rod 302.

[0023] In use, first insert the inner wall tube 2 into the outer wall tube 1, so that the first snap ring 301 is tightly snapped onto the outside of the inner wall tube 2 to ensure the stability of the initial installation. At this time, the sliding rod 302 hangs down naturally along the axial direction of the inner wall tube 2. The second snap ring 303 is located at one end close to the inner wall of the outer wall tube 1, which builds a basic framework for the subsequent installation and adjustment of the telescopic component 4, ensuring that the entire support component fits tightly with the double wall tube and can adapt to the initial pipe diameter range.

[0024] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The first rod 401 in the telescopic assembly 4 is fixedly mounted on the first card holder 402, the first card holder 402 is fixedly mounted on the first card ring 301, and the second rod 403 is connected to the first rod 401.

[0025] The second rod 403 in the telescopic assembly 4 is fixedly mounted on the second card seat 404, the second card seat 404 is fixedly mounted on the second snap ring 303, the other end of the second rod 403 is connected to the third card seat 405, and the other end of the first rod 401 is connected to the fourth card seat 406.

[0026] In use, when encountering double-walled pipes of different diameters, the second rod 403 is pulled or pushed by operating the connection between the first rod 401 and the second rod 403, so that it slides relative to the connecting axis with the first rod 401. Since the first retaining seat 402 and the second retaining seat 404 are respectively fixed on the first retaining ring 301 and the second retaining ring 303, and the first retaining ring 301 and the second retaining ring 303 are fixed in relative position with the inner wall pipe 2 and the outer wall pipe 1, the extension and retraction of the rods can accurately adapt to changes in pipe diameter, so that the support component can always provide stable and reliable support for the double-walled pipe, maintain the pipe wall shape, and avoid support failure due to differences in pipe diameter.

[0027] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The fixing piece 501 in the fastening component 5 is fixedly connected to the third card holder 405 and the fourth card holder 406. The end of the fixing piece 501 is provided with a fixing protrusion 502, and rubber protrusions 503 are evenly arranged between the fixing protrusions 502.

[0028] The snap ring 601 in the auxiliary component 6 is adapted to slide and engage with the sliding rod 302. The snap ring 601 is provided with a positioning hole 602, and the sliding rod 302 is provided with fixing holes 603 evenly distributed. The snap ring 601 is fixed to the sliding rod 302 by a positioning pin.

[0029] In use, after the telescopic component 4 is adjusted to the correct position, the fixing plate 501 of the sturdy component 5, with its rigid structure, strengthens the connection between the third card holder 405 and the fourth card holder 406, thereby improving the stability of the entire support structure. The fixing protrusion 502 is locked onto the inner wall of the outer wall tube 1 to further prevent component displacement. The rubber protrusion 503 acts as a buffer and shock absorber when the tube wall is subjected to slight external impact, protecting the tube wall from damage. At the same time, the locking ring 601 of the auxiliary component 6 is slid along the sliding rod 302 to the appropriate position, so that the positioning hole 602 on the locking ring 601 is aligned with the corresponding fixing hole 603 on the sliding rod 302. Then, the positioning pin is inserted to firmly fix the locking ring 601, thereby locking the adjusted position of the telescopic component 4 and preventing the rod from loosening due to vibration and other factors during subsequent use. This ensures the long-term stable operation of the support component and improves the overall production efficiency.

[0030] 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.
