[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its primary functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage regulation (magnetic saturation transformer). Based on their application, they can be divided into power transformers and special transformers (furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, medium-frequency transformers, high-frequency transformers, impulse transformers, instrument transformers, electronic transformers, reactors, mutual inductors, etc.). Each transformer is located next to a distribution cabinet, which contains numerous wires. Cable clamps are used to keep the wires separate.

[0003] After searching, the Chinese patent CN205543714U in the prior art discloses a wire clamp for a transformer distribution cabinet, comprising a first shell, the top of one side of the first shell being movably connected to the bottom of one side of the second shell through a first pin shaft, an opening being formed between the top of the other side of the first shell and the bottom of the other side of the second shell, the first shell being clamped with a first clamping device through a slot opened on its surface, the first clamping device comprising a first threaded cap, the internal thread of the first threaded cap being connected to a first threaded column, the top of the first threaded column being movably connected to a first bearing, the top of the first bearing being fixedly connected to an arc plate, and the bottom end of the first threaded column being fixedly connected to a rotating handle. The utility model utilizes the arrangement of a second threaded column, a second threaded cap and a first fixing rod to close the first shell and the second shell and fix them tightly, and by arranging the first threaded column, the first threaded cap and the arc plate, space in the distribution cabinet is saved.

[0004] However, the arc-shaped plate of the wire clamp of the utility model has no limiting structure on both sides. The arc-shaped plate will also rotate synchronously during movement and cannot correctly fit the surface of the wire to achieve the clamping purpose. Moreover, it can only clamp one wire at a time, and cannot meet the purpose of clamping multiple wires of different models at the same time. It cannot meet the production needs. Therefore, a wire clamp for a transformer distribution cabinet is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a wire clamp for a transformer distribution cabinet, which has the advantages of clamping multiple wires of different models at the same time. It solves the problem that there is no limiting structure on the left and right sides of the arc plate of the wire clamp, the arc plate will also rotate synchronously during movement and cannot correctly fit the surface of the wire to achieve the clamping purpose, and only one wire can be clamped at a time, which cannot meet the purpose of clamping multiple wires of different models at the same time.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a wire clamp for a transformer distribution cabinet, comprising a wire clamp body, a fixing mechanism for fixing the wire clamp body provided on the right side of the wire clamp body, and adjustment mechanisms for clamping wires of different sizes provided on the upper and lower sides of the wire clamp body;

[0008] Furthermore, the fixing mechanism includes a first spring fixedly connected to the right side of the wire clamp body, a first pull rod fixedly sleeved on the inner wall of the first spring, a second pull rod inserted into the right side surface of the wire clamp body and two third springs fixedly connected to the second pull rod close to the side of the wire clamp body, and a slot is provided on the right side of the first pull rod.

[0009] Furthermore, the clamping mechanism includes a clamping plate fixedly connected to one end of the connecting seat close to the movable plate, a plurality of second springs fixedly connected to the side of the clamping plate away from the connecting seat, and an anti-slip pad fixedly connected to the side of the second spring away from the clamping plate.

[0010] Furthermore, a plurality of sliding grooves are provided on the inner side of the wire clamp body, and the left and right sides of the second threaded sleeve are slidably connected in the sliding grooves.

[0014] Compared with the prior art, the utility model provides a wire clamp for a transformer distribution cabinet, which has the following beneficial effects:

[0015] 1. The wire clamp for transformer distribution cabinet realizes the surface clamping of wires by threading the second threaded rod to drive the anti-skid pad on the lower side of the connecting seat, and uses the telescopic rod to achieve the limiting effect, and uses two movable shafts to rotate in the movable plate to adjust the two anti-skid pads on the lower side to achieve the purpose of clamping wires of different sizes.

[0016] 2. The wire clamp for the transformer distribution cabinet uses the elastic action of the first spring to clamp the first pull rod into the wire clamp body and pull the second pull rod to cooperate with the elastic action of the third spring to clamp it into the clamping slot, so that the first pull rod can be clamped inside the right side of the wire clamp body, thereby separating the upper and lower sides of the wire clamp body, solving the problem that the arc plate of the wire clamp has no limiting structure on both sides, and the arc plate will rotate synchronously during movement and cannot correctly fit with the surface of the wire to achieve the clamping purpose, and each time it is used, it can only clamp one wire, and cannot meet the purpose of clamping multiple wires of different models at the same time.

[0024] See also Figure 1-5 In this embodiment, a wire clamp for a transformer distribution cabinet includes a wire clamp body 1. A fixing mechanism for securing the wire clamp body 1 is provided on the right side of the wire clamp body 1. Adjustment mechanisms for clamping wires of different sizes are provided on the upper and lower sides of the wire clamp body 1. The adjustment mechanism includes a first threaded sleeve 2 fixedly sleeved on the inner side of the wire clamp body 1, a first threaded rod 3 threadedly connected to the inner side of the first threaded sleeve 2, a movable plate 4 rotatably sleeved on one side of the first threaded rod 3, movable shafts 9 rotatably sleeved on the left and right sides of the movable plate 4, a connecting base 7 fixedly sleeved on the outer side of the movable shaft 9, a telescopic rod 8 fixedly connected to the side of the connecting base 7 away from the movable plate 4, a second threaded rod 6 rotatably sleeved on the upper side of the connecting base 7, a second threaded sleeve 5 threadedly connected to the outer side of the second threaded rod 6, and a clamping mechanism provided on the side of the movable plate 4 away from the connecting base 7.

[0025] Among them, the fixing mechanism includes a first spring 11 fixedly connected to the right side of the wire clamp body 1, a first pull rod 10 fixedly sleeved on the inner wall of the first spring 11, a second pull rod 12 inserted into the right side surface of the wire clamp body 1 and two third springs 17 fixedly connected to the side of the second pull rod 12 close to the wire clamp body 1, a slot 18 is provided on the right side of the first pull rod 10, the clamping mechanism includes a clamping plate 14 fixedly connected to the end of the connecting seat 7 close to the movable plate 4, a plurality of second springs 15 fixedly connected to the side of the clamping plate 14 away from the connecting seat 7 and an anti-slip pad 16 fixedly connected to the side of the second spring 15 away from the clamping plate 14, a plurality of sliding grooves 13 are provided on the inner side of the wire clamp body 1, the left and right sides of the second threaded sleeve 5 are slidably connected in the sliding grooves 13, the side of the third spring 17 away from the second pull rod 12 is vertically fixed to the right inner wall surface of the wire clamp body 1, the middle part of the left side of the wire clamp body 1 is rotatably sleeved with a rotating shaft, the side of the telescopic rod 8 away from the connecting seat 7 is fixedly connected to the inner wall surface of the wire clamp body 1, and the plurality of second springs 15 are arranged equidistantly in the horizontal direction.

[0026] It should be noted that the wire clamp body 1 uses the rotating shaft on the left side to achieve rotational separation or approach of the upper and lower sides, and the lower side slot 18 of the first pull rod 10 is inserted or separated by one end of the second pull rod 12 to achieve the fixing and separation effect on the right side of the wire clamp body 1, which facilitates the quick separation between the wire clamp body 1 and the wire.

[0027] The working principle of the above embodiment is:

[0028] The wire clamp body 1 is fixedly installed at the designated position of the transformer distribution cabinet, and then the wire clamp body 1 is sleeved on the surface of the two wires. Then, the lower side of the first pull rod 10 passes through the wire clamp body 1 and extends to the outside, and the second pull rod 12 moves outward. After the lower side of the first pull rod 10 passes through the wire clamp body 1, the third spring 17 is used to elastically clamp one side of the second pull rod 12 into the slot 18 opened in the first pull rod 10 to sleeve the wire clamp body 1 on the outer side of the wire. Then, the first threaded rod 3 can be rotated according to the diameter of the wire to adjust the distance between the movable plates 4, expand or reduce the distance between the two movable plates 4, and better clamp the wire. During the movement of the movable plate 4, the left and right sides of the second threaded sleeve 5 will also slide and move synchronously in the slide groove 13. Then, the second threaded rod 6 is threaded to drive the clamping plate 14 on the lower side of the connecting seat 7 to move toward the side of the wire. The elastic action of the second spring 15 can make the anti-slip pad 16 fit the surface of the wire more tightly, and during the movement of the connecting seat 7, the movable shaft 9 can be used to rotate in the movable plate 4 so that the clamping plate 14 is always perpendicular to the upper and lower sides of the wire.
