Detailed Implementation

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 As shown, Figure 1 This is a structural view of the adjustable manual threading machine.

[0025] The adjustable manual threading machine of this utility model includes a fixing part 1, a threaded part 2, and a connecting part 3. The two fixing parts 1 are detachably connected by the connecting part 3. Each fixing part 1 is provided with a placement groove 11, which is semi-circular. The placement grooves 11 of the two fixing parts 1 form a complete circle. The two threaded parts 2 are detachably connected in the two placement grooves 11 respectively. The pipe to be threaded is placed between the two threaded parts 2, and the outer wall of the pipe is in contact with the threads of the threaded parts 2. By detaching the two fixing parts 1, the two fixing parts 1 can be symmetrically arranged on both sides of the pipe. The connecting part 3 allows the two threaded parts 2 to contact and clamp the pipe. By rotating the whole formed by the connection of the two fixing parts 1, the threading operation of the threaded parts 2 on the pipe can be realized.

[0026] Specifically, the fixing part 1 is configured as a semi-circular ring, and the placement groove 11 and the fixing part 1 are coaxially arranged, thereby ensuring that when the fixing part 1 is driven to rotate, the threaded part 2 rotates around the center of the placement groove 11, making the threading process more stable.

[0027] like Figures 2 to 6 As shown, Figure 2 This is a cross-sectional view of the structure of the fixing part; Figure 3 A bottom view of the connection structure between the fixing part and the threaded part; Figure 4 This is a top view of the structure of the fixing part; Figure 5 This is a front view of the structure of the threaded part; Figure 6 This is a top view of the structure of the threaded part.

[0028] The threaded part 2 is configured as a semi-circular plate. The bottom of the arc groove of the placement groove 11 is provided with a fixing groove 12. The fixing groove 12 extends along the bottom of the arc groove of the placement groove 11 to form a semi-circular ring. The arc edge of the threaded part 2 is located in the fixing groove 12. The extension radius of the fixing groove 12 is consistent with the arc surface radius of the threaded part 2, thereby ensuring the stable placement of the threaded part 2 in the placement groove 11.

[0029] Preferably, two positioning holes 13 are provided on the same fixing part 1. The two positioning holes 13 are symmetrically arranged about the center line of the fixing part 1. The positioning holes 13 extend radially on the fixing part 1 and are threaded holes. A locking hole 21 is provided on the arc surface of the threaded part 2. The locking hole 21 corresponds to the positioning hole 13. A fixing bolt 5 is internally threaded into the positioning hole 13, and the end of the fixing bolt 5 can be placed in the locking hole 21. This prevents the threaded part 2 and the fixing part 1 from rotating relative to each other around the axis, ensuring that the threaded part 2 rotates stably with the fixing part 1 during the threading process. At the same time, it also enables quick disassembly between the threaded part 2 and the fixing part 1.

[0030] Generally, the connecting part 3 includes a connecting block 31. Both ends of the fixing part 1 are provided with the connecting block 31. The connecting block 31 is provided with a connecting hole 32. The connecting blocks 31 of the two fixing parts 1 are provided in a one-to-one correspondence. The connecting holes 32 of the two corresponding connecting blocks 31 are coaxially arranged. The connecting bolt 6 passes through the connecting holes 32 of the two corresponding connecting blocks 31 and is connected by the connecting nut 7 to realize the detachable connection of the two fixing parts 1.

[0031] This utility model can be applied to various pipeline companies such as gas companies, water companies, sewage treatment companies, and heating companies in their daily emergency rescue and pipeline maintenance. This utility model is simple to use and is not affected by the environment or power supply. It can also flexibly adjust the size of the threading machine according to the actual situation on site before threading. At the same time, it can be easily replaced after long-term use or when the threads are damaged, which greatly reduces the work risk and improves the threading efficiency. It will be widely used in the future.

[0032] Example 2

[0033] The adjustable manual threading machine also includes a force-applying handle 4, which is detachably connected to the fixing part 1, thereby facilitating the rotation of the thread part 2 around the pipe via the force-applying handle 4.

[0034] The fixing part 1 is provided with a mounting block 14, which extends radially along the center line of the fixing part 1 on the outer circular surface of the fixing part 1. The mounting block 14 is provided with a mounting hole 15, which extends radially along the center line of the fixing part 1. The mounting hole 15 is a threaded hole. One end of the force-applying handle 4 is threadedly connected to the mounting hole 15, thereby ensuring that the force applied by the force-applying handle 4 to the fixing part 1 is stable.

[0035] Preferably, the bottom of the mounting hole 15 is provided with a through hole 16, which is coaxially arranged with the mounting hole 15, and the diameter of the through hole 16 is smaller than the diameter of the mounting hole 15. The threaded part 2 is provided with a fixing hole 22, which is a threaded hole. The fixing hole 22 and the through hole 16 are arranged in a one-to-one correspondence. The through hole 16 extends into the fixing groove 12, and a locking bolt passes through the through hole 16 and is threadedly connected to the fixing hole 22, thereby achieving a fixed connection between the threaded part 2 and the fixing part 1. The mounting block 14 ensures that the mounting hole 15 and the through hole 16 have appropriate lengths.

[0036] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
