Description

Technical field:

[0001] The utility model relates to the technical field of auxiliary wire pulling, in particular to an auxiliary wire pulling device. Background technology:

[0002] During the building decoration process, the wiring of wires is a relatively important step. The wiring directly affects the use of lighting and other equipment in the later stage. Reasonable wiring can bring convenience to the subsequent electricity use. For the sake of aesthetics, most wiring is buried inside the wall. This requires that during the wiring construction, the workers will insert the wires into the wire tube, then pull the wires out from the other end of the wire tube, and pass them through the socket box, so that the end of the wire has a section extending out of the socket box, so that there is enough length of wire to connect with the socket box. However, when pulling the wire, the workers are required to operate the insertion and pulling out positions. If only one worker pulls the wire directly at the wire outlet end, it will cause the wire to contact the right angle of the socket box opening, and the wire is pulled out along the right angle bend, which causes wear on the wire. At the same time, pulling is more laborious, affecting the efficiency of wiring.

[0003] To this end, someone proposed a Chinese utility model patent with patent number CN202221827545.6 and patent name "one-to-two wire pulling auxiliary device". The one-to-two wire pulling auxiliary device includes a clamping frame, a first mounting hole is opened on the top of the clamping frame, a second mounting hole is opened in the middle of the clamping frame, mounting bolts are clamped inside the first mounting hole and the second mounting hole, and a limiting roller is installed at the position of the top of the clamping frame corresponding to the first mounting hole. The utility model clamps the clamping frame in the wire box by setting a clamping frame, mounting bolts, limiting rollers, limiting rings, limiting holes, guide tubes and positioning holes. The wires pass through the limiting rollers and the guide tube positions and then pass into the wire tube. When the wires are pulled from the other end of the wire tube, the wires pass through the limiting rollers and the guide tube smoothly under the limitation and guidance of the limiting rollers and the guide tube. There is no need to equip workers at both ends of the wire tube to pull the wires, which saves labor for pulling the wires. The use of the auxiliary device makes the pulling of the wires smoother and less prone to damage, making the decoration wiring more convenient.

[0004] However, the above-mentioned one-to-two wire pulling assistant has some shortcomings: after the one-to-two wire pulling assistant is installed in the wire box through the clamping frame, the clamping frame does not have any structure to clamp and position with the wire box, and there is a problem that the clamping frame may be separated from the wire box, affecting the efficiency of wire pulling and wiring.

[0025] The utility model is further described below in conjunction with specific embodiments and drawings.

[0026] See Figure 1-7 As shown, an auxiliary wire puller comprises: a fixing frame 1 for fixing and clamping with a wire box, and a rotating body 2 installed on the fixing frame 1 and rotatable for wires to pass around, a window 10 for wires to pass through is formed between the rotating body 2 and the fixing frame 1, when in use, the fixing frame 1 is clamped and fixed on the wire box, the rotating body 2 is at the opening 31 of the wire box 3, when wiring / arranging wires, after the wires pass through the wire tube and enter the wire box 3, the ends of the wires pass around the rotating body 2 and extend out of the wire box 3, at this time, the wires can be pulled by pulling the ends of the wires outward with a small force, and the wires are in rotational contact with the rotating body 2, the friction is small, and the wear of the wires can be avoided, thereby ensuring the quality of the wires, and at the same time, the wire pulling action is smooth, the force can be reduced, and only one staff member is required to pull the wires, saving labor for wire pulling, and the use of the auxiliary device makes the wire pulling smoother and less prone to damage, making decoration wiring more convenient.

[0032] The sliding rod 12 includes a rod body 121, a first screw 122, and a second screw 123. The rod body 121 is provided with a first internal thread 101 and a second internal thread 102 at both ends. One end of the rod body 121 abuts against the inner side of the first clamping block 11. The first screw 122 passes through the first through hole 111 of the first clamping block 11 and is screwed with the first internal thread 101 of the rod body 121, so that one end of the rod body 121 is fixedly connected to the first clamping block 11. The assembly structure is extremely simple. The second screw 123 passes through the second through hole 131 of the second clamping block 13. Afterwards, it is spirally installed with the second internal thread 102 of the rod body 121, and the spring 14 is sleeved on the second screw 123, and one end of the spring 14 abuts against the inner side of the second clamping block 13, and the other end of the spring 14 abuts against one end of the rod body 121 with the second internal thread 102, so that a gap is formed between the rod body 121 and the inner side of the second clamping block 13, and its assembly structure is extremely simple. The spring 14 is located in the gap, and the second clamping block 13 can slide on the second screw 123, thereby ensuring that the fixing frame 1 can stably realize the clamping action with the wire box.

[0033] Among them, the second screw 123 includes a head 103, a bare rod segment 104, and a threaded segment 105 which are integrally connected in sequence, the head 103 is exposed on the outside of the second clamping block 13, the threaded segment 105 is screwed fixed in the second internal thread 102, the bare rod segment 104 is exposed in the gap between the rod body 121 and the second clamping block 13, the spring 14 is sleeved on the bare rod segment 104, the second clamping block 13 is sleeved on the bare rod segment 104 through the second through hole 131, and can slide on the bare rod segment 104, and its operation is more stable.

[0034] The rotating body 2 is described in detail below:

[0035] The rotating body 2 includes a metal shaft 21 and a rotating cylinder 22 which is sleeved on the metal shaft 21 and can rotate relative to the metal shaft 21. The two ends of the metal shaft 21 are respectively fixed in the mounting grooves 120 on the inner sides of the two sliding rods 12.

[0036] Alternatively, the rotating body 2 includes a rotating cylinder 22 and convex shafts disposed at both ends of the rotating cylinder 22 , and the convex shafts are rotatably installed in the installation grooves 120 on the inner sides of the two sliding rods 12 .

[0037] That is to say, the rotating body 2 has at least the above two structures. This embodiment, as a preferred embodiment, adopts: the rotating body 2 includes a metal shaft 21 and a rotating cylinder 22 that is sleeved on the metal shaft 21 and can rotate relative to the metal shaft 21, and the two ends of the metal shaft 21 are respectively fixed in the mounting grooves 120 on the inner sides of the two sliding rods 12; the rotating body 2 with this structure is more convenient to install, the first clamping block 11 and the second clamping block 13 define the positions of the two sliding rods 12, ensuring that the distance between the two sliding rods 12 remains unchanged, and the two ends of the metal shaft 21 are respectively fixed in the mounting grooves 120 on the inner sides of the two sliding rods 12, thereby ensuring that the two ends of the metal shaft 21 are stably installed on the fixing frame 1, ensuring the stability of the assembly structure, and assembling is also easier.

[0038] In addition, in order to make it more convenient to use, the following design is also made: the upper end surface of the second clamping block 13 is also provided with a quick release groove 132 for quickly removing the second screw 123, and the quick release groove 132 is connected to the second through hole 131. When it is necessary to separate the sliding rod 12 from the second clamping block 13, the second screw 123 can be screwed out relative to the rod body 121, but tools are required for disassembly, and the disassembly and assembly time is relatively long. Since the quick release groove 132 connected to the second through hole 131 is provided, the sliding rod 12 can be removed relative to the second clamping block 13 without tools, that is, the second screw 123 is pulled outward from the quick release groove 132 of the second clamping block 13, so that the sliding rod 12 and the second clamping block 13 can be separated, and the operation is extremely simple and the time is extremely short. Especially after the wire pulling is completed, the wire is still in the window between the rotating body 2 and the fixed frame 1, and the fixed frame 1 is removed relative to the wire box 3. When a section of the wire extends out of the wire box 3, the sliding rod 12 and the second clamping block 13 are directly separated, and the wire can be quickly taken out relative to the utility model, which is extremely convenient to use.

[0039] The cross-section of the quick-release slot 132 is a trapezoid with a large opening and a small bottom. The bottom of the quick-release slot 132 passes through the second through hole 131, and the width of the bottom of the quick-release slot 132 is smaller than the diameter of the second through hole 131. Of course, the width of the bottom of the quick-release slot 132 is slightly smaller than the diameter of the second through hole 131, thereby ensuring that the second screw 123 will not accidentally detach from the second through hole 131, and will only detach from the second through hole 131 and enter the quick-release slot 132 when the second screw 123 is pulled, thereby realizing the disassembly action.

[0040] In summary, when the utility model is in use, the fixing frame 1 is clamped and fixedly installed on the wire box, and the rotating body 2 is at the opening 31 of the wire box 3. When wiring / arranging the wires, after the wires pass through the wire tube and enter the wire box 3, the ends of the wires bypass the rotating body 2 and extend out of the wire box 3. At this time, the wires can be pulled outward by pulling the ends of the wires with a small force. The wires are in rotating contact with the rotating body 2, and the friction is small, which can avoid abrasion of the wires and ensure the quality of the wires. At the same time, the wire pulling action is smooth, which can reduce the force. Only one staff member is needed to pull the wires, saving labor for wire pulling. The use of the auxiliary device makes the wire pulling smoother. , not easy to be damaged, making decoration and wiring more convenient; in addition, the fixing frame 1 pushes out the second clamping block 13 through the elastic force of the spring 14, so that the second clamping block 13 moves in the direction away from the first clamping block 11, so that after the fixing frame 1 is installed in the opening 31 of the wiring box 3, the outer sides of the first clamping block 11 and the second clamping block 13 are in contact with the inner wall of the wiring box 3, and the second clamping block 13 is pushed out by the elastic force of the spring 14, so that the first clamping block 11 and the second clamping block 13 are clamped and fixed to the inner wall of the wiring box, thereby ensuring that the fixing frame 1 and the wiring box 3 are assembled more stably, preventing the fixing frame 1 from accidentally falling out of the wiring box, ensuring the wire pulling / wiring efficiency, and making it more convenient to use.
