For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] See also Figure 1 The embodiment of the present application provides a pipe threading mechanism, including a main body 1, a plurality of support members 2 and a plurality of guide members 3, the main body 1 is annular; the plurality of support members 2 are sequentially arranged along the circumference of the main body 1, the support member 2 includes a holding end 21, a connecting end 23 and an abutting end 22 connected in sequence, the connecting end 23 is rotatably connected to the main body 1, and the opposite ends of the connecting end 23 are respectively connected to the holding end 21 and the abutting end 22; the plurality of guide members 3 are sequentially arranged along the circumference of the main body 1 and are rotatably connected to the main body 1.

[0036] In practical applications, multiple support members 2 and multiple guide members 3 can be evenly spaced in sequence along the circumference of the main body 1, so that the force on the main body 1 is more evenly applied, thereby extending the service life of the main body 1. The support member 2 includes a holding end 21, a connecting end 23, and an abutting end 22. The holding end 21 and the abutting end 22 are connected to the opposite sides of the connecting end 23, respectively. The abutting end 22 extends into the pipe 5, and the connecting end 23 is rotatably connected to the main body 1. In this way, the support member 2 forms a lever structure. The operator only needs to hold the holding end 21 and apply force to rotate it, which can drive the abutting end 22 to rotate, so that the abutting end 22 abuts against the inner wall of the pipe 5, thereby achieving the effect of fixing the pipe-threading mechanism to the pipe 5 opening.

[0037] Specifically, along the axial direction of the main body 1, the holding end 21 extends away from one end of the main body 1 toward the outside of the main body 1, and the abutting end 22 extends away from one end of the main body 1 toward the inside of the main body 1. The abutting ends 22 of multiple support members 2 are arranged around the first threading cavity 25, and the multiple guide members 3 are arranged around the second threading cavity 31 and are used to support cables. The abutting ends 22 are used to abut against the inner wall of the pipe 5, and the first threading cavity 25 and the second threading cavity 31 are used for threading cables.

[0038] In actual application, the holding end 21 extends away from one end of the main body 1 to the outside of the main body 1, and the abutting end 22 extends away from one end of the main body 1 to the inside of the main body 1. With this arrangement, the holding ends 21 of the multiple support members 2 are in an open state. During operation, the operator holds the holding end 21 and brings the two hands close to each other to drive the holding end 21 to rotate so that the abutting end 22 abuts against the pipe 5. This structure is convenient for the operator to hold and apply force; at the same time, the abutting end 22 extends away from the inside of the main body 1, so that the abutting ends 22 of the multiple support members 2 are in a contracted state when not working, which makes it easy for the abutting end 22 to extend into the pipe 5 and adapt to pipes 5 of various diameters.

[0039] In addition, the present application is also provided with a plurality of guide members 3, which are rotatably connected to the main body 1, and the plurality of guide members 3 are arranged around the second threading cavity 31, and the plurality of abutment ends 22 are arranged around the first threading cavity 25. When the cable is threaded, it passes through the second threading cavity 31 and the first threading cavity 25 in sequence and extends into the pipe 5. When the cable is located in the second threading cavity 31, the guide member 3 is used to support the cable to reduce the friction between the cable and the main body 1. The operator does not need to lift the cable by hand, which saves time and effort. The guide member 3 can also assist the operator to extend the cable into the pipe 5, effectively improving the threading efficiency.

[0040] It should be noted that the main body 1 has a central axis, which is usually located near the center position of the main body 1 in the length, width or height direction, and roughly divides the main body 1 into two symmetrical parts; extending outside the main body 1 refers to the direction away from the central axis, and extending inside the main body 1 refers to the direction close to the central axis.

[0041] Compared with the prior art, the pipe threading mechanism of the present application includes a main body 1, a plurality of support members 2 and a plurality of guide members 3, wherein the plurality of support members 2 and the plurality of guide members 3 are arranged in sequence along the circumference of the main body 1, respectively, and the support member 2 includes a holding end 21, a connecting end 23 and an abutting end 22, and the connecting end 23 is connected to the holding end 21 and the abutting end 22 on opposite sides thereof, and the holding end 21 extends toward the outside of the main body 1 at one end away from the main body 1, and the abutting end 22 extends toward the inside of the main body 1 at one end away from the main body 1. The operator only needs to It is necessary to hold the holding end 21, and the two hands can be brought close to each other to drive the holding end 21 to rotate, so that the abutting end 22 abuts against the pipe 5, which is convenient for the operator to hold and apply force; at the same time, the abutting end 22 is in a contracted state when not working, which makes it convenient for the abutting end 22 to extend into pipes 5 of various diameters; the guide member 3 is used to support the cable and reduce the friction between the cable and the main body 1. The operator does not need to lift the cable by hand, which saves time and effort. The guide member 3 can also assist the operator to extend the cable into the pipe 5, effectively improving the efficiency of pipe threading.

[0042] See also Figure 2 and Figure 3 The abutting end 22 includes a first part 221 and a second part 222. One end of the first part 221 is connected to the connecting end 23, and the other end is connected to the second part 222 and extends in the direction close to the central axis of the main body 1. One end of the second part 222 is connected to the first part 221, and the other end is a free end 223. The free end 223 is used to abut against the inner wall of the pipe 5 and extend in the direction away from the central axis of the main body 1.

[0043] In actual application, the abutment end 22 includes a first part 221 and a second part 222 connected in sequence along its length direction. The first part 221 extends in a direction close to the central axis, and the second part 222 extends in a direction away from the central axis. In this way, the connection between the first part 221 and the second part 222 is closer to the central axis than the rest of the abutment end 22. The first threading cavity 25 is formed by a plurality of connection points. In this way, when the cable passes through the first threading cavity 25, the plurality of connection points can clamp the cable. On the one hand, it plays a role in positioning the cable, so that the cable is located at the center of the pipe 5, and the friction between the cable and the inner wall of the pipe 5 can be reduced; on the other hand, only the connection of the abutment end 22 is in contact with the cable, which reduces the friction between the cable and the abutment end 22, making it easier for the operator to push the cable into the pipe 5.

[0044] See also Figure 4 For the sake of clarity, Figure 4 The middle dashed line represents the central axis of the main body 1, the angle between the extension direction of the second portion 222 and the central axis is set to α degrees, and the angle between the extension direction of the first portion 221 and the central axis is set to β degrees, wherein α<β. In this way, the second portion 222 is closer to the central axis than the first portion 221, so that the second portion 222 can be extended into the pipe 5 and adapt to the pipe 5 with a smaller diameter.

[0045] See also Figure 3 The abutting end 22 includes a supporting portion 224 , which is rotatably connected to the free end 223 , and the supporting portion 224 is used to contact the pipe 5 .

[0046] In actual application, the supporting portion 224 is connected to the side of the free end 223 away from the first threading cavity 25, and the supporting portion 224 is rotatably connected to the free end 223. When the operator rotates the holding end 21 to make the multiple abutting ends 22 in an open state, the supporting portion 224 abuts against the inner wall of the pipe 5, which on the one hand plays a role in fixing the threading mechanism. On the other hand, when the supporting portion 224 is subjected to the abutting force of the inner wall of the pipe 5, the supporting portion 224 can rotate relative to the free end 223, and fit with the inner wall of the pipe 5 in a more adaptive posture, thereby improving the fixing stability of the threading mechanism at the mouth of the pipe 5.

[0047] See again Figure 3 The support member 2 further includes a rolling member 24 , which is rotatably connected to a connection point between the first portion 221 and the second portion 222 , and the rolling member 24 at least partially extends into the first threading cavity 25 .

[0048] In actual applications, the connection points of the multiple first parts 221 and the second parts 222 are arranged in a ring to form a first threading cavity 25, and a rolling element 24 is arranged at the connection point, and the rolling element 24 at least partially extends into the first threading cavity 25. In this way, when the cable passes through the first threading cavity 25, the cable contacts the rolling element 24, which can reduce the friction between the cable and the connection point. The rolling element 24 can also assist in the advancement of the cable, thereby effectively improving the efficiency of cable laying.

[0049] See also Figure 5 The main body 1 includes a plurality of first fixing members 11 and a plurality of second fixing members 12, which are alternately connected in the circumferential direction to form a closed cavity 13, the first fixing members 11 and the second fixing members 12 are detachably connected, the second fixing members 12 are rotatably connected to the connecting end 23, and the closed cavity 13 is used for the cable to pass through.

[0050] In actual application, the main body 1 is formed by a plurality of first fixing members 11 and a plurality of second fixing members 12 connected alternately in sequence. The first fixing member 11 can be used to connect the guide member 3, and the second fixing member 12 can be used to connect the support member 2. This makes the overall design of the main body 1 more balanced, the structural layout more reasonable, and the degree of structural integration is improved; at the same time, the first fixing member 11 and the second fixing member 12 are connected in a detachable manner. When transporting or not in use, the first fixing member 11 and the second fixing member 12 can be removed to reduce the size of the device and facilitate transportation and carrying; when in use, only the first fixing member 11 and the second fixing member 12 need to be installed together, which is easy to operate and has a relatively simple structure.

[0051] See again Figure 5 The guide member 3 is located on the inner side of the main member 1 and is close to the central axis of the main member 1 .

[0052] In practical applications, the guide member 3 is closer to the central axis than the main body 1, so that when the cable is passed through, the guide member 3 supports the cable to prevent the cable from contacting the main body 1, and to prevent the main body 1 from scratching the outer sheath of the cable, causing damage to the cable. At the same time, the guide member 3 can also assist the cable to extend into the pipe 5, thereby improving the efficiency of cable laying.

[0053] See again Figure 5 The inner side surface of the first fixing member 11 is arc-shaped, and a plurality of first fixing holes 111 are opened at opposite ends of the first fixing member 11, and a plurality of second fixing holes 121 are opened at opposite ends of the second fixing member 12. The first fixing holes 111 and the second fixing holes 121 are arranged opposite to each other, and the first fixing holes 111 and the second fixing holes 121 are connected by fixing members to fix the first fixing member 11 and the second fixing member 12.

[0054] In practical applications, the first fixing member 11 and the second fixing member 12 can be chamfered on one side close to the central axis to prevent scratching the cable; the first fixing member 11 is provided with a plurality of first fixing holes 111, and the second fixing member 12 is provided with a plurality of second fixing holes 121. The first fixing holes 111 and the second fixing holes 121 are connected by fixing members so that the first fixing member 11 and the second fixing member 12 are fixed together.

[0055] It should be noted that the fixing member may be a screw or a bolt.

[0056] See again Figure 5 The main body 1 also includes a third fixing member 14, which is arranged at the bottom of the first fixing member 11 along the axial direction of the main body 1. The two ends of the third fixing member 14 extend in a direction close to the central axis of the main body 1 to form two spaced extension portions 141. The two ends of the guide member 3 are rotatably connected to the extension portions 141 through a rotating shaft; the outer periphery of the guide member 3 has a wire groove 32.

[0057] In practical applications, the third fixing member 14 is mainly used to fix the guide member 3, which is convenient for installation and removal of the guide member 3. The third fixing member 14 can be connected to the bottom of the first fixing member 11, and two extensions 141 are provided at two ends of the third fixing member 14, and the extensions 141 extend in a direction close to the central axis. The guide member 3 is rotatably connected to the extensions 141, so that when the cable is passed through, the guide member 3 is located at the end of the cable, and the guide member 3 supports the cable, which can prevent the cable from hanging down at the end of the cable and prevent the cable from contacting the main member 1. The guide member 3 is closer to the central axis than the main member 1, so that the guide member 3 can better support the cable.

[0058] The guide member 3 is provided with a wire groove 32, and the cable is located in the wire groove 32, which can better position the cable and avoid cable deviation. At the same time, the third fixing member 14 can also be detachably connected to the first fixing member 11, such as detachably connected by screws, which is conducive to the installation and replacement of the guide member 3 and further makes the structural design more convenient.

[0059] See also Figure 6 The pipe threading mechanism also includes a tightening member 4. When the plurality of abutting ends 22 abut against the inner wall of the pipe 5, the tightening member 4 is sleeved on the outer circumference of the plurality of holding ends 21 to limit the separation of the abutting ends 22 from the pipe 5.

[0060] In actual application, when the operator rotates the holding end 21 so that the abutting end 22 abuts against the inner wall of the pipe 5, in order to free the operator's hands and allow the pipe threading mechanism to be better fixed to the pipe 5 mouth, the present application provides a tightening member 4. After the abutting end 22 abuts against the inner wall of the pipe 5, the tightening member 4 is sleeved on the outer periphery of the multiple holding ends 21. The tightening member 4 is tightened to pull the multiple holding ends 21 in a direction close to each other, thereby preventing the abutting end 22 from separating from the pipe 5 and improving the connection stability between the pipe threading mechanism and the pipe 5 mouth.

[0061] It should be noted that the tightening member 4 can adopt existing technology, such as a ratchet tightener or the like.

[0062] The embodiment of the present application also provides a pipe threading method, using the above-mentioned pipe threading mechanism, the pipe threading method comprises the following steps:

[0063] S1, extending the abutting end 22 into the pipe 5;

[0064] Among them, the abutting end 22 includes a first part 221, a second part 222 and a supporting part 224. The second part 222 and the supporting part 224 can be extended into the pipe 5. In this way, when the holding end 21 is rotated, the first part 221 can be prevented from colliding with the pipe 5, which affects the abutment between the supporting part 224 and the inner wall of the pipe 5.

[0065] S2, rotating the holding end 21 toward the central axis of the main body 1 until the abutting end 22 abuts against the inner wall of the pipe 5;

[0066] The operator rotates the holding end 21 to drive the abutting end 22 to rotate away from the central axis, so that the abutting portion 224 of the abutting end 22 abuts against the inner wall of the pipe 5, so that the pipe-threading mechanism can be fixed to the opening of the pipe 5.

[0067] S3, placing the cable in the second threading cavity 31, the guide member 3 receives the cable, and then extends the cable from the first threading cavity 25 into the pipe 5.

[0068] Among them, along the axial direction of the main body 1, the guide member 3 is connected to the bottom of the main body 1, and the guide member 3 is located at the end of the cable. The guide member 3 supports the cable to prevent the cable from hanging down at the end of the cable and the cable from contacting the main body 1. The guide member 3 is closer to the central axis than the main body 1. The guide member 3 is provided with a wire groove 32, and the cable is located in the wire groove 32, so that the guide member 3 can better support the cable and prevent the cable from deflecting; the cable is successively passed through the second threading cavity 31 and the first threading cavity 25 and extends into the pipe 5; a rolling member 24 is provided at the first threading cavity 25. When the cable is passed through, the cable contacts the guide member 3 in the second threading cavity 31 and contacts the rolling member 24 in the first threading cavity 25, which greatly reduces the friction between the cable and the main body 1, and the guide member 3 and the rolling member 24 can both assist in the advancement of the cable component and improve the cable laying efficiency.
