Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] To address the technical problem that pipes can only be rounded for a single inner diameter specification, this invention provides a pipe rounding device that can round pipes with different inner diameter specifications.

[0023] It should be noted that the pipe rounding device described in this utility model is used in, but not limited to, corrugated pipes. For ease of explanation, this utility model only uses the application of a pipe rounding device to a corrugated pipe as an example. The principle of the pipe rounding device applied to other types of equipment is essentially the same as that applied to a corrugated pipe, and will not be described in detail here.

[0024] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of a pipe support device according to an embodiment of the present invention. The pipe support device includes a fixed block 1, a screw 2, a support block 3, a slider 4, and a driving component 5. The screw 2 is rotatably connected to the fixed block 1. There are several support blocks 3, each distributed around the screw 2 and capable of reciprocating in the direction of the screw 2. Each support block 3 has an inclined surface 31 on the side facing the screw 2. The slider 4 is threaded 44 onto the screw 2 and abuts against each inclined surface 31. The driving component 5 is used to drive the screw 2 to rotate and can stop the slider 4 at any position of its sliding stroke. The support blocks 3 gather or disperse as the slider 4 moves.

[0025] In this embodiment, the supporting blocks 3 form a supporting structure for the pipe. The inclined surface 31 and the slider 4 are arranged so that when the drive member 5 drives the screw 2 to rotate, each supporting block 3 moves synchronously with the slider 4, thus making the device suitable for pipes of different diameters.

[0026] Furthermore, the drive component 5 can be a handle or a motor. The screw 2 can be rotated by manually turning the handle, or the screw 2 can be rotated by energizing the motor. Preferably, the end of the screw 2 passes through the fixing block 1 and is welded with a hexagonal block. With the setting of the hexagonal block, the operator can choose to rotate the screw 2 manually or electrically.

[0027] Preferably, each supporting block 3 is evenly distributed around the screw 2 and can reciprocate in the direction of the screw 2.

[0028] In one embodiment, the slider 4 includes a first adjusting ring 41, an adjusting rod 42, and a second adjusting ring 43. The first adjusting ring 41, the adjusting rod 42, and the second adjusting ring 43 are fixedly connected in sequence. The inner wall threads 44 of the first adjusting ring 41 and the second adjusting ring 43 are sleeved on the screw 2. The outer walls of the first adjusting ring 41 and the second adjusting ring 43 slide against each inclined surface 31.

[0029] In this embodiment, in order to adapt to the inclined surface 31, the outer diameters of the first adjusting ring 41 and the second adjusting ring 43 are different sizes. The first adjusting ring 41 and the second adjusting ring 43 are used together to drive each supporting block 3, so that each supporting block 3 is more stable during the contact process.

[0030] In one embodiment, the inner walls of the first adjusting ring 41 and the second adjusting ring 43 are both provided with threads 44 that are adapted to the screw 2.

[0031] In one embodiment, the outer walls of the first adjusting ring 41 and the second adjusting ring 43 are provided with a plurality of slots 45, and each inclined surface 31 corresponds to each slot 45, and the inclined surface 31 is slidably embedded in the slot 45.

[0032] In this embodiment, the slot 45 effectively prevents the first adjusting ring 41 and the second adjusting ring 43 from rotating together with the screw 2, so that the first adjusting ring 41 and the second adjusting ring 43 can only move back and forth along the length direction of the screw 2 under the action of the screw 2 rotation.

[0033] In one embodiment, grooves 32 parallel to the inclined surface 31 are provided on both sides of the inclined surface 31, and first protrusions 46 parallel to the inclined surface 31 are provided on the opposite side of the slot 45. The two first protrusions 46 are slidably embedded in the two grooves 32 respectively.

[0034] In this embodiment, the first protrusion 46 and the second sliding groove 32 are provided to ensure that each support block 3 is always connected to the first adjusting ring 41 and the second adjusting ring 43, thereby preventing the support block 3 from falling off on its own.

[0035] In one embodiment, the fixing blocks 1 are arranged in pairs, the two ends of the screw 2 are rotatably connected between the two fixing blocks 1, and the two ends of each supporting round block 3 are slidably connected to the opposite surfaces of the two fixing blocks 1.

[0036] In this embodiment, the arrangement of two fixing blocks 1 makes the screw 2 more stable.

[0037] In one embodiment, the opposing surfaces of the two fixed blocks 1 are provided with a plurality of pairs of second protrusions 11, each pair of second protrusions 11 corresponding to each supporting round block 3, and the end of the supporting round block 3 is slidably embedded between the two second protrusions 11.

[0038] In this embodiment, the two protrusions form a slide, which prevents the ends of the support blocks 3 from shifting during movement, thus ensuring the normal operation of each support block 3.

[0039] In one embodiment, a fixing rod 12 is provided between the two fixing blocks 1, and the two ends of the fixing rod 12 are respectively fixed to the two fixing blocks 1.

[0040] In this embodiment, the function of the fixing rod 12 is to ensure that the two fixing blocks 1 remain stationary during the rotation of the screw 2.

[0041] In one embodiment, the support block 3 has a rounded corner 33 on one side that abuts against the inner wall of the pipe.

[0042] In this embodiment, the function of the rounded corner 33 is to prevent damage to the inner wall of the pipe during the process of the supporting rounded block 3 abutting against the inner wall of the pipe.

[0043] In one embodiment, the support block 3 has anti-slip texture 34 on one side that abuts against the inner wall of the pipe.

[0044] In this embodiment, the anti-slip texture 34 is used to prevent the rounding block 3 from slipping during the contact process, thus affecting the rounding effect.

[0045] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0046] First, the fixed block 1 without the drive component 5 is inserted into the pipe; then, the fixed block 1 with the drive component 5 is held by hand, and the drive component 5 starts to drive the screw 2 to rotate; next, the first adjusting ring 41 and the second adjusting ring 43 move towards the lower end of the inclined surface 31 as the screw 2 rotates, and each supporting block 3 moves synchronously away from the screw 2 as the first adjusting ring 41 and the second adjusting ring 43 move. After each supporting block 3 abuts against the inner wall of the pipe, it continues to move until the recessed part returns to its original shape. At this time, the screw 2 and the pipe are coaxial, and the supporting work is completed. By utilizing the characteristic of each supporting block 3 opening or closing synchronously, the function of being applicable to pipes of different diameters is realized.

[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
