[0027] Example 1

[0028] Reference Figure 1-Figure 5 As shown, the utility model discloses a device for preventing the spiral lock tube 3 from twisting, comprising:

[0029] A support assembly 1, comprising a support frame 11 and two center frames 12, wherein the two center frames 12 are symmetrically arranged on the support frame 11 and are arranged along the length direction of the support frame 11;

[0030] The adjusting assembly 2 includes a first adjusting frame 21, a second adjusting frame 22, a plurality of first screw rods 23 and a plurality of second screw rods 24. The plurality of first screw rods 23 are arranged on the top of the support frame 11, and the plurality of second screw rods 24 are passed through the center frame 12. The first adjusting frame 21 and the second adjusting frame 22 are arranged in parallel on the top of the support frame 11, and the two sides of the first adjusting frame 21 and the second adjusting frame 22 are respectively slidably connected with the first screw rod 23 and the second screw rod 24. The first screw rod 23 and the second A buffer nut 28 is provided at one end of the screw rod 24 close to the first adjusting frame 21, and a first elastic element 25 is provided between the side wall of the first adjusting frame 21 and the buffer nut 28; an adjusting nut 29 is provided at one end of the first screw rod 23 and the second screw rod 24 close to the second adjusting frame 22; a second elastic element 26 is provided between the side wall of the second adjusting frame 22 and the adjusting nut 29; and a plurality of rollers 27 are respectively provided between the first adjusting frame 21 and the second adjusting frame 22, and an arc groove 271 is provided on the surface of the roller 27.

[0031] It can be seen that the two center frames 12 in the support assembly 1 of the present invention are symmetrically mounted on the support frame 11. The four top corners of the support frame 11 are used to mount the first screw rod 23, and the center frame 12 is used to mount the second screw rod 24. The first adjustment frame 21 and the second adjustment frame 22 are arranged parallel to each other between the first screw rod 23 and the second screw rod 24, and the two sides of the first adjustment frame 21 and the second adjustment frame 22 are respectively slidably connected to the first screw rod 23 and the second screw rod 24, that is, the first adjustment frame 21 and the second adjustment frame 22 reciprocate up and down along the first screw rod 23 and the second screw rod 24. The first adjustment frame 21 is arranged at the bottom, and the second adjustment frame 22 is arranged at the top of the first adjustment frame 21. A plurality of rollers 27 are arranged axially along the length between the first adjustment frame 21 and the second adjustment frame 22. The spiral lock tube 3 passes between the upper and lower groups of rollers 27. As a preferred embodiment, the surface of the roller 27 is provided with an arc groove 271 for tightly fitting with the spiral lock tube 3. Specifically, a buffer nut 28 is provided at the bottom of the first and second screw rods 23 and 24. A first elastic element 25 is provided between the sidewall of the first adjustment frame 21 and the bottom buffer nut 28; a second elastic element 26 is provided between the sidewall of the second adjustment frame 22 and the top adjustment nut 29. The buffer nut 28 and the adjustment nut 29 are respectively used to restrain one end of the first and second elastic elements 25 and 26. When the spiral locking tube 3 is fed from one end and enters between the upper two sets of rollers 27, the arc-shaped grooves on the surfaces of the rollers 27 allow the spiral locking tube 3 to move axially between the two sets of rollers 27, ensuring that the spiral locking tube 3 maintains the correct path and direction during the molding process. Furthermore, the tensioning force applied to the first and second elastic elements 25 and 26 effectively relieves the internal stress of the spiral locking tube 3 during production, preventing stress concentration and thus regulating and positioning pressure.

[0032] The utility model can effectively release the stress generated by the spiral locking tube 3 during the production process, avoid stress concentration, and ensure the structural integrity and service life of the spiral locking tube 3; secondly, the multiple arc rollers 27 arranged axially can keep the collective size of the spiral locking tube 3 consistent, ensuring the performance of the pipeline during installation and use.

[0033] Furthermore, a sleeve 231 is provided between the first screw rod 23 and the first adjustment frame 21 and the second adjustment frame 22, respectively, and the sleeve 231 is sleeved on the outside of the first screw rod 23. A slide 241 is provided between the second screw rod 24 and the first adjustment frame 21 and the second adjustment frame 22, respectively, and the slide 241 is sleeved on the outside of the second screw rod 24.

[0034] Specifically, the arrangement of the sleeve 231 and the slide 241 can ensure that the first adjustment frame 21 and the second adjustment frame 22 can ensure smooth sliding on the first screw rod 23 and the second screw rod 24. Preferably, the interior of the sleeve 231 is a light hole structure, and the size of the sleeve 231 is larger than the diameter of the first screw rod 23 to avoid jamming during sliding; the size of the slide 241 is equal to the diameter of the second screw rod 24.

[0035] Furthermore, a limiting nut is provided on a side of the slide 241 away from the second elastic element 26 , and the limiting nut is sleeved on the outer side of the second screw rod 24 .

[0036] Specifically, the limiting nut is set on the side of the slide 241 away from the second elastic element 26 (the bottom of the slide 241 ), which is used to limit the lowest position of the second adjustment frame 22 to ensure the distance between the first support frame 11 and the second support frame 11.

[0037] Furthermore, a locking block 15 is provided on the central frame 12 , a locking bolt 16 is passed through the locking block 15 , and the locking bolt 16 abuts against the second screw rod 24 .

[0038] Specifically, the second screw rod 24 is passed through the center frame 12 , and the second screw rod is locked on the center frame 12 by the cooperation of the locking block 15 and the locking bolt 16 , and the locking bolt 16 is tightened to fix the second screw rod.

[0039] Furthermore, a support shaft 272 is provided between the first adjustment frame 21 and the second adjustment frame 22 , and the roller 27 is sleeved on the support shaft 272 . A bearing 273 is provided between the support shaft 272 and the roller 27 .

[0040] Specifically, the roller 27 is sleeved on the outside of the support shaft 272 to support the rotation of the roller 27. Preferably, a bearing 273 is installed between the support shaft 272 and the roller 27 to ensure the flexibility of the rotation of the roller 27. As a preferred embodiment of the present invention, the arc groove 271 on the surface of the roller 27 can be used to select a roller 27 of corresponding size according to the diameter of the spiral lock tube 3 passing through, ensuring a tight fit between the spiral lock tube 3 and the roller 27. Secondly, the material of the roller 27 is nylon. The nylon arc-shaped roller 27 can effectively reduce the friction between the spiral tube and the roller 27, and has the characteristics of good wear resistance, light weight, easy processing, and low price.

[0041] Furthermore, locking nuts 274 are provided at both ends of the support shaft 272. Specifically, the locking nuts 274 can effectively ensure the stability of the support shaft 272, limit the axial direction of the support shaft 272, and prevent the support shaft 272 from falling off during the rotation process.

[0042] Furthermore, a mounting plate 13 is provided at the bottom of the support frame 11, and fixing bolts 14 are provided around the mounting plate 13. The entire support frame 11 is fixed by the fixing bolts 14 to ensure the stability of the entire device.
