[0010] Compared with the prior art, the present invention has the following beneficial effects: By passing the cable through the cable hole on the lower side of the shell and utilizing the rotation of the second adjusting wheel and the transmission wheel, convenient adjustment of the cable inside and outside the shell is achieved, so that the user can easily adjust the cable whether inside or outside the power distribution cabinet. The cable is squeezed by the clamping plate during movement to ensure the friction between the transmission wheel and the cable, so that the cable can rotate together with the transmission wheel, thereby achieving smooth transmission of the cable and significantly improving the transmission efficiency of the cable, avoiding the problem of unstable transmission caused by insufficient friction. By setting the first adjusting wheel and the first gear, as well as the gear ratio between the inner gear ring and the first gear, the transmission wheel can be quickly rotated when the first adjusting wheel is slightly turned, so that the user can complete the extension or pull-out of the cable in a short time, effectively saving manpower and time costs. The cable is naturally clamped between the wire clamps during the movement process of being attached to the inner wall of the pressing plate. At this time, the screw is rotated to rotate on the rotating sleeve, thereby pulling the rotating sleeve and the wire clamp to move to one side together, and the part of the cable that contacts the wire clamp is bent accordingly, and then stored in the interior of the accommodating frame. After the cable is pulled from below, since the screw is immovable, the internal fixing plate moves in the mounting groove inside the rotating sleeve, and squeezes the spring to deform it, so that the cable pulled into the accommodating frame is pulled out again, thereby avoiding the connection between the cable and the shell from being subjected to excessive pulling force, and correspondingly making this part less likely to be worn or cracked, thereby reducing the service life of the cable. It should be added that when the cable loses the pulling force, the spring will rebound and drive the cable to be pulled back into the accommodating frame for repeated use; When the switching component generates magnetic attraction, it will attract the limit block to drive the slider to slide upward inside the clamping block and tightly against the switching component. At this time, the abutment block is tightly embedded in the groove and exerts pressure on the transmission wheel to limit the transmission wheel and prevent it from rotating again, thereby completing the locking function of the transmission wheel. In actual use, it can prevent the cable from shaking and escaping from the inside of the distribution cabinet; When the internal magnetic poles of the fixed cylinder and the rotating cylinder are the same, the guiding effect of the magnetic field can be used to allow the magnetic field to be conducted downward along the second metal plate and the third metal plate, showing magnetism to the outside, and being able to generate a stable attraction to the limit block, so that it is firmly fixed on the third metal plate. When the twisting block is twisted to rotate the rotating cylinder, the magnetic poles on the upper and lower sides are opposite, and the magnetic field becomes a closed-circuit state, showing non-magneticity to the outside, thereby cleverly solving the problem of releasing the limit block, so that the limit block is no longer attracted, and the corresponding abutment block is also out of contact with the transmission wheel, so that the transmission wheel is in a rotatable state. This technical solution not only simplifies the operation process and improves work efficiency, but also reduces equipment failure rate and improves production safety. It has a simple structure, is easy to manufacture and is low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-Figure 7The line fixing device for an electric power distribution cabinet shown in the figure comprises a shell 1, in which a transmission wheel 10 is rotatably installed inside the shell 1, a rotating plate 14 is fixedly connected to one side of the outer wall of the transmission wheel 10, and a uniformly distributed connecting plate 13 is fixedly connected to the outer wall of the rotating plate 14, and a linkage ring 12 is fixedly connected to the outer wall of the connecting plate 13, and a second adjusting wheel 5 is fixedly connected to the outer wall of the linkage ring 12, and the second adjusting wheel 5 is inserted and rotatably connected to the outer wall of the shell 1, and a clamping plate 15 is fixedly installed inside the shell 1, and cable holes for cables to pass through are opened on the upper and lower surfaces of the outer wall of the shell 1, and the cables are passed through the cable holes on the lower side to the inside of the shell 1, and then the user can rotate the transmission wheel 10 by twisting the second adjusting wheel 5 exposed at any position above or below, and the squeezing of the clamping plate 15 can ensure that the rotation of the transmission wheel 10 has sufficient friction to drive the cable to rotate together with the transmission wheel 10, and pass through the cable hole on the upper side, so that the user can adjust the cable inside and outside the distribution cabinet.

[0014] A second gear 9 is fixedly connected to the other side of the outer wall of the shell 1, and a first gear 8 is rotatably connected to the side of the inner wall of the shell 1 close to the second gear 9 through an axis, and the first gear 8 is meshed with the second gear 9.

A first adjusting wheel 4 is fixedly connected to the outer wall of the inner gear ring 7, and the first adjusting wheel 4 is inserted and rotatably connected to the outer wall of the shell 1. The user can drive the internal first gear 8 to rotate by twisting the first adjusting wheel 4 exposed at any point above or below, and the first gear 8 drives the transmission wheel 10 to rotate by meshing with the second gear 9. In the process, the gear ratio between the inner gear ring 7 and the first gear 8 greatly increases the rotation amplitude, and then the transmission wheel 10 can be driven to rotate quickly when the first adjusting wheel 4 is slightly turned, so that the user can quickly adjust the extension or pull-out of the cable.

[0015] The clamping plate 15 is configured as a semicircular structure, and clamping sleeves 25 are fixedly connected to both sides of the outer wall of the transmission wheel 10. By configuring the semicircular clamping plate 15 and the clamping sleeve 25, the cable can be tightly attached to the transmission wheel 10, thereby ensuring that the transmission wheel 10 can stably drive the cable to move.

[0016] When the first adjusting wheel is turned, the transmission wheel can rotate quickly, thereby greatly improving the efficiency of cable adjustment, allowing the user to quickly adjust the extension or pull-out of the cable, saving valuable time. By passing the cable through the cable hole on the lower side of the shell 1 and utilizing the rotation of the second adjusting wheel 5 and the transmission wheel 10, convenient adjustment of the cable inside and outside the shell 1 is achieved, so that the user can easily adjust the cable whether inside or outside the distribution cabinet. The cable is squeezed during movement by the clamping plate 15 to ensure the friction between the transmission wheel 10 and the cable, so that the cable can rotate with the transmission wheel 10, thereby achieving smooth transmission of the cable and significantly improving the transmission efficiency of the cable, avoiding the problem of unstable transmission caused by insufficient friction. By setting the first adjusting wheel 4 and the first gear 8, as well as the gear ratio between the inner gear ring 7 and the first gear 8, the transmission wheel 10 can be quickly rotated when the first adjusting wheel 4 is slightly turned, so that the user can complete the extension or pull-out of the cable in a short time, effectively saving manpower and time costs.

[0017] A buffer component is provided on one side of the outer wall of the shell 1, and the buffer component provides a buffer section when the cable is pulled. The buffer component includes a receiving frame 2 fixedly connected to one side of the outer wall of the shell 1, and a threaded seat 3 is fixedly connected to the side of the receiving frame 2 away from the shell 1. A screw 20 is inserted and screwed inside the threaded seat 3, and a rotating sleeve 19 is inserted and rotatably connected to the inner wall of the screw 20, and the rotating sleeve 19 is inserted and slidably connected to the inside of the receiving frame 2. A through hole 16 is opened on the outer wall of the pressing plate 15, and the rotating sleeve 19 is inserted and slidably connected to the inside of the receiving frame 2. A wire clamp 17 is provided on one side of the movable sleeve 19, and the wire clamp 17 is inserted and slidably connected to the outside of the through hole 16, and a pull rod 18 is fixedly connected to the end of the through hole 16.

A plug rod 22 is fixedly connected to one side of the outer wall of the pull rod 18, and the plug rod 22 is inserted and slidably connected to the inner wall of the limit plate 23. The end of the plug rod 22 is fixedly connected to a fixed plate 21, and the fixed plate 21 and the limit plate 23 are fixedly connected. There is a spring 24, and the spring 24 is sleeved on the outer wall of the insertion rod 22. The cable is naturally clamped between the wire clamps 17 during the movement of the cable against the inner wall of the clamping plate 15. At this time, the screw 20 is rotated to make it rotate on the rotating sleeve 19, thereby pulling the rotating sleeve 19 and the wire clamp 17 to move to one side together, and accordingly, the part of the cable that contacts the wire clamp 17 is bent and then retracted into the interior of the accommodating frame 2. After the cable is pulled from below, since the screw 20 is immovable, the internal fixing plate 21 moves in the mounting groove inside the rotating sleeve 19 and squeezes the spring 24 to deform it, so that the cable pulled into the accommodating frame 2 is pulled out again, thereby avoiding the cable being subjected to excessive pulling force at the connection point where the cable is attached to the inside of the shell 1, and correspondingly making this part less likely to be worn or cracked, thereby reducing the service life of the cable. It should be added that when the cable loses the pulling force, the spring 24 will rebound and drive the cable to be pulled back into the interior of the accommodating frame 2 for repeated use.

[0018] The housing 1 is provided with a locking assembly inside, and the locking assembly is used to limit the rotation of the transmission wheel 10. The locking assembly includes a switching assembly and a contact assembly. The switching assembly is used to drive the contact assembly to contact the transmission wheel 10. The contact assembly includes a clamping block 26 fixedly connected to the inner wall of the housing 1, and a slider 27 is inserted and slidably connected inside the clamping block 26. The top of the slider 27 is fixedly connected to a limit block 30, and the limit block 30 is set to a magnetic matching material. A pair of abutment blocks 29 are fixedly connected to the outer wall of the slider 27, and the outer wall of the transmission wheel 10 A groove 28 is provided on the upper surface, and the shape of the groove 28 is adapted to that of the abutment block 29. When the switching component generates magnetic attraction, the limit block 30 will be attracted to drive the slider 27 to slide upward inside the clamping block 26 and tightly abut against the switching component. At this time, the abutment block 29 is tightly embedded in the groove 28 and exerts pressure on the transmission wheel 10 at the same time, thereby limiting the transmission wheel 10 and preventing it from rotating again, thereby completing the locking function of the transmission wheel 10. In actual use, it can prevent the cable from shaking and escaping from the inside of the distribution cabinet.

[0019] The switching assembly includes a pair of connecting frames 31 fixedly connected to the top of the inner wall of the shell 1, a fixed cylinder 32 is fixedly connected between the connecting frames 31, a rotating cylinder 33 is rotatably connected to the top of the fixed cylinder 32, a first metal plate 34 is fixedly connected to the top of the inner wall of the rotating cylinder 33, a pair of second metal plates 35 are fixedly connected to the inner side wall of the rotating cylinder 33, a pair of first strong magnetic blocks 36 arranged up and down are fixedly connected between the second metal plates 35, and the magnetic pole directions of the pair of first strong magnetic blocks 36 correspond to each other, a pair of third metal plates 38 are fixedly connected to the inner wall side of the fixed cylinder 32, and the third metal plate 38 is abutted against the second metal plate 35, a second strong magnetic block 37 is fixedly connected between the pair of third metal plates 38, and the magnetic pole directions of the second strong magnetic block 37 and the first strong magnetic block 36 correspond to each other, an insertion shaft 11 is fixedly connected to the top of the rotating cylinder 33, and the insertion shaft 11 is inserted and rotatably connected to the outer wall of the shell 1, and the top of the insertion shaft 11 is fixed It is connected with a torsion block 6, and the materials of the first strong magnetic block 36 and the second strong magnetic block 37 are both set to neodymium iron boron strong magnet. When the internal magnetic poles of the fixed cylinder 32 and the rotating cylinder 33 are the same, the guiding effect of the magnetic field is utilized so that the magnetic field can be conducted downward along the second metal plate 35 and the third metal plate 38, showing magnetism to the outside, and can generate a stable attraction to the limit block 30, so that it is firmly fixed on the third metal plate 38. When the torsion block 6 is twisted to rotate the rotating cylinder 33, the magnetic poles on the upper and lower sides are opposite, and the magnetic field becomes a closed circuit state, showing non-magnetism to the outside, thereby cleverly solving the release problem of the limit block 30, so that the limit block 30 is no longer attracted, and the corresponding abutment block 29 is also out of contact with the transmission wheel 10, so that the transmission wheel 10 is in a rotatable state. This technical solution not only simplifies the operation process and improves work efficiency, but also reduces the equipment failure rate and improves production safety. It has a simple structure, is easy to manufacture, and is low in cost.

[0020] Working principle: By passing the cable through the cable hole on the lower side of the housing 1 and utilizing the rotation of the second adjusting wheel 5 and the transmission wheel 10, convenient adjustment of the cable inside and outside the housing 1 is achieved, so that the user can easily adjust the cable whether inside or outside the power distribution cabinet. The cable is squeezed during movement by the clamping plate 15 to ensure the friction between the transmission wheel 10 and the cable, so that the cable can rotate together with the transmission wheel 10, thereby achieving smooth transmission of the cable and significantly improving the transmission efficiency of the cable, avoiding the problem of unstable transmission caused by insufficient friction. By setting the first adjusting wheel 4 and the first gear 8, as well as the gear ratio between the inner gear ring 7 and the first gear 8, the transmission wheel 10 can be quickly rotated when the first adjusting wheel 4 is slightly turned, so that the user can complete the extension or pull-out of the cable in a short time, effectively saving manpower and time costs. The cable is naturally clamped between the wire clamps 17 during the movement process of being attached to the inner wall of the pressing plate 15. At this time, the screw 20 is rotated to rotate on the rotating sleeve 19, thereby pulling the rotating sleeve 19 and the wire clamp 17 to move to one side together, and accordingly, the part of the cable in contact with the wire clamp 17 is bent, and then retracted into the interior of the accommodating frame 2. After the cable is pulled from below, since the screw 20 is immovable, the internal fixing plate 21 moves in the mounting groove inside the rotating sleeve 19, and squeezes the spring 24 to deform it, so that the cable pulled into the accommodating frame 2 is pulled out again, thereby avoiding the connection between the cable and the inside of the shell 1 from being subjected to excessive pulling force, and correspondingly making this part less likely to be worn or cracked, thereby reducing the service life of the cable. It should be added that when the cable loses the pulling force, the spring 24 will rebound and drive the cable to be pulled back into the interior of the accommodating frame 2 for repeated use; When the switching component generates magnetic attraction, it will attract the limit block 30 to drive the slider 27 to slide upward inside the clamping block 26 and tightly against the switching component. At this time, the abutment block 29 is tightly embedded in the groove 28, and at the same time, pressure is applied to the transmission wheel 10, thereby limiting the transmission wheel 10 to prevent it from rotating again, thereby completing the locking function of the transmission wheel 10, which can prevent the cable from shaking and escaping from the inside of the distribution cabinet in actual use; When the internal magnetic poles of the fixed cylinder 32 and the rotating cylinder 33 are the same, the guiding effect of the magnetic field can be used to allow the magnetic field to be conducted downward along the second metal plate 35 and the third metal plate 38, showing magnetism to the outside, and being able to generate a stable attraction to the limit block 30, so that it is firmly fixed on the third metal plate 38. When the torsion block 6 is twisted to rotate the rotating cylinder 33, the magnetic poles on the upper and lower sides are opposite, and the magnetic field becomes a closed-circuit state, showing no magnetism to the outside, thereby cleverly solving the release problem of the limit block 30, so that the limit block 30 is no longer attracted, and the corresponding abutment block 29 is also out of contact with the transmission wheel 10, so that the transmission wheel 10 is in a rotatable state. This technical solution not only simplifies the operation process and improves work efficiency, but also reduces the equipment failure rate and improves production safety. It has a simple structure, is easy to manufacture, and is low in cost.
