DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 9 The present invention provides a technical solution: a vacuum double-walled tube fixing bracket, comprising: a supporting component, a positioning component and a fixing component. According to the length of the inner tube 2, different numbers of positioning components are evenly installed on the outer wall thereof. The positioning component comprises two fixing plates 5. The two fixing plates 5 are both arc-shaped, and a connecting plate 6 is fixedly installed on the inner end. An anti-skid pad 7 is fixedly installed on the inner end of each connecting plate 6. The two fixing plates 5 are fixed together by bolts. An ear plate 8 is fixedly installed on the front and rear sides of both ends of each fixing plate 5. Two adjacent ear plates 8 are fixedly connected by bolts. At the same time, the anti-skid pad 7 is in close contact with the outer wall of the inner tube 2, and the fixing plate 5 is fixedly installed. On the outer wall of the inner tube 2, it is convenient to disassemble and assemble the fixing plate 5, and to fix the fixing plate 5 at different positions of the inner tube 2. An arc hole 9 is opened on the side wall of each fixing plate 5. A rotating rod 14 is slidably connected in the arc hole 9. The front and rear ends of the rotating rod 14 pass through the arc hole 9 and are fixedly installed with a support rod 13. A top plate 11 is fixedly installed at one end of the support rod 13, and a cylinder 31 is fixedly installed on the side of the support rod 13 close to the top plate 11. The top plate 11 is located at the outer end of the fixing plate 5, and the outer end of the inner tube 2 is provided with an outer tube 1. The fixing plate 5 is located between the inner tube 2 and the outer tube 1, and the sum of the diameters of the fixing plate 5 and the inner tube 2 is smaller than the inner diameter of the outer tube 1.

[0022] The arc-shaped hole 9 extends from the inner end to the outer end of the fixing plate 5. A rubber block 10 is fixedly installed on the outer wall of each fixing plate 5 at the inner end of the arc-shaped hole 9. A limiting hole 15 is provided at one end of each support rod 13 away from the top plate 11. The limiting hole 15 is located on the inner side of the rotating rod 14. When the rotating rod 14 is located at the inner end of the arc-shaped hole 9, one end of the rubber block 10 is inserted into the limiting hole 15 by squeezing itself to fix the support rod 13 and the top plate 11. At this time, the inner end of the top plate 11 contacts the outer end of the fixing plate 5, and the top plate 11 is contracted to the outer side of the fixing plate 5, so that the inner tube 2 is inserted into the inner end of the outer tube 1.

[0023] The top plate 11 is in an arc shape, and a rubber pad 12 is fixedly installed on the outer end of the top plate 11. When the rotating rod 14 is located at the outer end of the arc hole 9, the top plate 11 contacts the inner wall of the outer tube 1 by squeezing the rubber pad 12. The rubber pad 12 increases the friction between the top plate 11 and the inner wall of the outer tube 1. After the positioning component is fixed to the outer end of the inner tube 2, and the steel wire is passed through the cylinder 31 located on the same horizontal line, the inner tube 2 and the positioning component are inserted into the outer tube 1 with the steel wire. One person fixes the steel wire, and the other person rotates the inner tube 2. When the inner tube 2 rotates, it will rotate with the fixing plate 5. When the fixing plate 5 rotates, it will drive the rotating rod 14 through the arc hole 9 to move the support rod 13 and the top plate 11. The steel wire prevents the top plate 11 from rotating with the fixing plate 5. When the support rod 13 moves, the rubber block 10 disengages from the limiting hole 15, allowing the rubber pad 12 to be in close contact with the inner wall of the outer tube 1, supporting the inner tube 2 in the outer tube 1, and pulling out the steel wire at the same time.

[0025] One end of the threaded column 16 is rotatably connected with a contact plate 17, and the lower end of the contact plate 17 is fixedly connected to one end of the anti-slip block 18, and one end of the threaded tube 19 is rotatably connected with a contact plate 20, and the upper end of the contact plate 20 is fixedly connected to one end of the anti-slip block 21, and the outer end of the threaded tube 19 is fixedly installed with a driving block 22, and the other end of the threaded column 16 is inserted into the inner side of the other end of the threaded tube 19, and the outer wall of the threaded column 16 is threadedly connected to the inner wall of the threaded tube 19, and the driving block 22 is a nut and is welded on the outer wall of the threaded tube 19. By connecting the wrench and the driving block 22, the threaded tube 19 can be driven to rotate, thereby changing the length between the threaded column 16 and the threaded tube 19, so that the anti-slip block 18 and the outer wall of the anti-slip ring 24 are in close contact, and the anti-slip block 21 and the inner wall of the anti-slip ring 3 are in close contact, thereby fixing the inner tube 2 at both ends of the outer tube 1, supporting the two ends between the outer tube 1 and the inner tube 2, and also preventing the inner tube 2 from rotating in the outer tube 1.

[0026] The supporting components include two arc-shaped plates 23, a supporting column 24 and a supporting tube 25. The upper and lower ends of each arc-shaped plate 23 are fixedly installed with ear plates 27. The two arc-shaped plates 23 are sleeved on the outer ends of the outer tube 1 and are fixedly connected by bolts. The supporting column 24 is L-shaped, one end of the supporting column 24 is fixedly installed at the center of the arc-shaped plate 23, and the other end is evenly provided with a plurality of through holes 28. The lower end of the supporting tube 25 is fixedly installed with a bottom plate 26, and the four ends of the bottom plate 26 are provided with fixing holes 30. The upper end of the supporting tube 25 is fixedly provided with a bottom plate 26, and the bottom plate 26 is provided with a fixing hole 30. A bolt hole 29 is opened at the end, and the upper end of the support tube 25 is slidably sleeved on the lower side of the other end of the support column 24 and fixed by a bolt. One end of the bolt passes through the bolt hole 29 and one of the through holes 28 and is threadedly connected with a nut to support the outer tube 1. By connecting the bolts with different through holes 28, the height between the support column 24 and the support tube 25 can be adjusted, thereby adjusting the supporting position of the base plate 26. It can be suitable for uneven ground environments, reduces the burden of laying mats for staff, and has good practicality.

[0027] In actual use, the positioning component is fixed to the outer end of the inner tube 2, and the steel wire is passed through the cylinder 31 located on the same horizontal line, and then the inner tube 2 and the positioning component are inserted into the outer tube 1 with the steel wire. One person fixes the steel wire, and the other person rotates the inner tube 2. When the inner tube 2 rotates, it will rotate the fixing plate 5. When the fixing plate 5 rotates, it will drive the rotating rod 14 to move the support rod 13 and the top plate 11 through the arc hole 9. The steel wire prevents the top plate 11 from rotating with the fixing plate 5. When the support rod 13 moves, the rubber block 10 is disengaged from the limiting hole 15, so that the rubber pad 12 and the outer tube 1 The inner wall is in close contact, the inner tube 2 is supported in the outer tube 1, and the steel wire is pulled out at the same time, the threaded tube 19 and the threaded column 16 are placed on the anti-slip ring 1 3 and the anti-slip ring 2 4, and the threaded tube 19 can be driven to rotate by connecting the wrench and the driving block 22, thereby changing the length between the threaded column 16 and the threaded tube 19, making the anti-sliding block 18 and the outer wall of the anti-slip ring 2 4 in close contact, and the anti-sliding block 21 and the inner wall of the anti-slip ring 3 in close contact, thereby fixing the inner tube 2 at both ends of the outer tube 1, supporting the two ends between the outer tube 1 and the inner tube 2, and preventing the inner tube 2 from rotating in the outer tube 1.
