Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically to a cable threading device for cable processing. Background Technology

[0002] A cable is a conductor made of one or more mutually insulated conductors and an outer insulating protective layer. It is used to transmit electricity or information and has the characteristics of being internally energized and externally insulated. In a broad sense, the distinction between cables and wires is blurred. Generally, those with complex structures and large cross-sectional areas are called cables, while those with smaller cross-sectional areas are called wires.

In addition, the orientation of the cable threading seat can be freely changed by rotating the movable head in the movable slot without moving the entire device, which is convenient and labor-saving.

[0004] During cable processing, cable threading devices are needed to thread cables through cable conduits. However, existing cable threading devices are difficult to thread cables through cable conduits quickly and stably. This not only reduces the efficiency of cable threading but also affects the effectiveness of the cable threading device. Utility Model Content

[0011] Preferably, the end of the positioning block furthest from the fixing sleeve has a V-shaped structure.

[0012] Preferably, the limiting component includes a limiting groove and a limiting block; the fixed base A has a plurality of limiting grooves arranged in a circular array in the through hole groove; the limiting block is slidably inserted in the limiting groove and fixedly connected to the outer circumferential surface of the rotating cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a cable clamping assembly, places one end of the cable between two clamping blocks. Then, by rotating the knob on the rotating rod through the positioning assembly, the rotating rod drives the rotating disk to rotate in the rotating groove, causing the circumferential surface of the sliding pin to press against the inner wall of the sliding groove, causing the two clamping blocks to move relative to each other, and the two guide blocks to slide relative to each other in the guide groove, and the sliding pin to slide in the sliding groove until the opposing surfaces of the two clamping blocks contact the surface of the cable.

[0015] 2. This utility model, by setting up a positioning component and a limiting component, allows the rotating cylinder to slide within a spring groove when pulled, causing the fixing sleeve to slide within an annular groove. This causes the return spring to contract, allowing the positioning block to slide within a positioning groove and the limiting block to slide within a limiting groove, until the side of the limiting block contacts the inner wall of the limiting groove. At this point, the positioning block moves out of the annular groove and into the spring groove. The insertion of the positioning block into the positioning groove fixes the position of the rotating disk within the rotating groove, making the clamping of the cable by the two cable clamping blocks more stable. Furthermore, the limiting component not only prevents the rotating cylinder from rotating but also limits its range of movement, thereby improving the practicality of this utility model.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 7 This utility model provides a technical solution: a cable threading device for cable processing, comprising a cable threading device body 1, a cable clamping assembly 2, and a positioning assembly 3; the cable threading device body 1 includes a connecting pipe 101, a connecting bracket 102, and a drive wheel 103; the three connecting brackets 102 are arranged in a ring array and connected to the outer circumferential surface of the connecting pipe 101; the two drive wheels 103 are rotatably connected to the connecting brackets 102;

[0031] The cable clamping assembly 2 is arranged inside the connecting pipe 101; the cable clamping assembly 2 includes a fixed seat A201, a fixed seat B202, a rotating groove 203, a rotating disk 204, a rotating rod 205, a cable clamping block 206, a sliding groove 207, a sliding pin 208, a guide groove 209, and a guide block 210; the fixed seats A201 and B202 are symmetrically arranged on both sides of the connecting pipe 101 and are fixedly connected to the connecting pipe 101; the fixed seat A201 has a rotating groove 203 on the side near the fixed seat B202; the rotating disk 204 is rotatably disposed in the rotating groove 203 by the positioning assembly 3; the rotating rod 205 is fixed on the side of the rotating disk 204 away from the fixed seat B202, and the end of the rotating rod 205 extends outward through the fixed seat A201. Two cable clamping blocks 206 are symmetrically arranged inside the connecting pipe 101; a sliding groove 207 is provided on the side of the cable clamping block 206 away from the fixed seat B202, and the two sliding grooves 207 are symmetrically arranged at the center; a sliding pin 208 slides through the sliding groove 207 and is fixedly connected to the rotating disk 204; the cable clamping block 206 has an arc-shaped structure, and the two cable clamping blocks 206 form a cable clamping cavity, and the opposite surfaces of the two cable clamping blocks 206 are in contact with the surface of the cable; a guide groove 209 is provided on the side of the fixed seat B202 near the fixed seat A201; a guide block 210 is fixed on the cable clamping block 206 and slides in cooperation with the guide groove 209; when the two cable clamping blocks 206 are in contact, the circumferential surface of the sliding pin 208 is not in contact with the inner wall of the sliding groove 207.

[0032] This invention uses a cable clamping assembly 2 to place one end of the cable between two clamping blocks 206. Then, by rotating a knob on a rotating rod 205 via a positioning assembly 3, the rotating rod 205 drives a rotating disk 204 to rotate within a rotating groove 203. This causes the circumferential surface of a sliding pin 208 to press against the inner wall of a sliding groove 207, resulting in relative movement of the two clamping blocks 206. This allows the two guide blocks 210 to slide relative to each other within a guide groove 209, and the sliding pin 208 to slide within a sliding groove 207, until the opposing surfaces of the two clamping blocks 206 contact the surface of the cable. Finally, the positioning assembly 3 rotates the knob... The disc 204 is fixed in position within the rotating groove 203, making the two cable clamping blocks 206 hold the cable more stably. Then, the cable threading device body 1 is placed inside the cable pipe and moves inside the cable pipe via the drive wheel 103. At the same time, it drives the cable held by the two cable clamping blocks 206 to perform the cable threading operation. After the cable threading is completed, the cable can be removed from between the two cable clamping blocks 206 by the positioning component 3. Compared with the prior art, this utility model has a simple and reasonable structure, ingenious design, and can quickly and stably thread the cable from the cable pipe. It has high threading efficiency and good performance.

[0033] In a preferred embodiment, the positioning component 3 includes a spring groove 301, a rotating cylinder 302, an annular groove 303, a fixing sleeve 304, a return spring 305, a positioning groove 306, and a positioning block 307. The rotating groove 301 is formed within the rotating groove 203. The rotating cylinder 302 passes through the spring groove 301 via a limiting component 4 and is sleeved on the rotating rod 205. The rotating disk 204 has an annular groove 303 on the side near the rotating cylinder 302. The fixing sleeve 304 is slidably disposed within the annular groove 303 and fixedly connected to the end of the rotating cylinder 302. The return spring 305 is sleeved on the rotating cylinder 302, and both ends of the return spring 305 are fixedly connected to the inner wall of the spring groove 301 and the fixing sleeve 304, respectively. A plurality of positioning blocks are arranged in a circular array within the annular groove 303. The positioning groove 306; a number of positioning blocks 307 are fixed in a ring array on the side of the fixed sleeve 304 away from the rotating cylinder 302 and are inserted into the positioning groove 306; the longitudinal section of the rotating cylinder 302 is L-shaped, and the size of the side of the rotating cylinder 302 near the fixed sleeve 304 is smaller than the size of the side of the rotating cylinder 302 away from the fixed sleeve 304, so as to facilitate the movement of the rotating cylinder 302 by hooking the L-shaped end of the rotating cylinder 302; the end of the positioning block 307 away from the fixed sleeve 304 is V-shaped. The inclined surface of the positioning block 307 can guide the insertion of the positioning block 307 into the positioning groove 306. The plane of the positioning block 307 can prevent the positioning block 307 from moving out of the positioning groove 306 due to the force generated by the opposite movement of the two cable clamping blocks 206;

[0034] The limiting component 4 includes a limiting groove 401 and a limiting block 402; the fixed base A201 has three limiting grooves 401 arranged in a ring array in the through hole groove; the limiting block 402 slides through the limiting groove 401 and is fixedly connected to the outer circumferential surface of the rotating cylinder 302; when the side of the limiting block 402 contacts the inner side wall of the limiting groove 401, the return spring 305 can continue to retract.

[0035] This invention, by setting a positioning component 3 and a limiting component 4, allows the rotating cylinder 302 to slide within the spring groove 301 when pulled, causing the fixing sleeve 304 to slide within the annular groove 303. This causes the return spring 305 to contract under force, allowing the positioning block 307 to slide within the positioning groove 306 and the limiting block 402 to slide within the limiting groove 401, until the side of the limiting block 402 contacts the inner wall of the limiting groove 401. At this point, the positioning block 307 moves out of the annular groove 303 and into the spring groove 301. Through the insertion of the positioning block 307 into the positioning groove 306, the position of the rotating disk 204 within the rotating groove 203 can be fixed, making the clamping of the cable by the two cable clamping blocks 206 more stable. Furthermore, the limiting component 4 not only prevents the rotating cylinder 302 from rotating but also limits the range of movement of the rotating cylinder 302, thereby improving the practicality of this invention.

[0036] Working principle: In use, place one end of the cable between the two clamping blocks 206. Then, pull the rotating cylinder 302, causing it to slide within the spring groove 301, and the fixing sleeve 304 to slide within the annular groove 303. This causes the return spring 305 to contract, allowing the positioning block 307 to slide within the positioning groove 306, and the limiting block 402 to slide within the limiting groove 401, until the side of the limiting block 402 contacts the inner wall of the limiting groove 401. At this point, the positioning block... 307 is moved out of the annular groove 303 and into the spring groove 301. Then, the knob on the rotating rod 205 is rotated, causing the rotating rod 205 to drive the rotating disk 204 to rotate in the rotating groove 203. This causes the circumferential surface of the sliding pin 208 to press against the inner wall of the sliding groove 207, causing the two cable clamping blocks 206 to move relative to each other. This causes the two guide blocks 210 to slide relative to each other in the guide groove 209, and the sliding pin 208 to slide in the sliding groove 207 until the two cable clamping blocks 206 face each other. When the rotating cylinder 302 contacts the surface of the cable, it is released. Under the elastic force of the return spring 305, the rotating cylinder 302 will cause the fixed sleeve 304 to slide in the opposite direction within the spring groove 301, causing the limiting block 402 to slide in the opposite direction within the limiting groove 401 until the other side of the limiting block 402 contacts the other inner wall of the limiting groove 401. At this time, the side of the fixed sleeve 304 contacts the inner wall of the annular groove 303, and the positioning block 307 is inserted into the positioning groove 306, allowing the rotation to proceed. The disc 204 is fixed in position within the rotating groove 203, making the two cable clamping blocks 206 hold the cable more stably. Then, the cable threading device body 1 is placed inside the cable pipe and moves inside the cable pipe via the drive wheel 103. At the same time, it drives the cable held by the two cable clamping blocks 206 to perform the cable threading operation until the cable threading is completed. Then, by pulling the rotating cylinder 302, the positioning block 307 is moved out of the annular groove 303, and the cable can be removed from between the two cable clamping blocks 206.

[0037] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
