Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and specifically to a wiring structure for a power distribution cabinet. Background Technology

[0002] Distribution cabinets are a key component in power systems, mainly used for distributing, controlling, and protecting power supply. The functions of distribution cabinets are mainly divided into: power distribution, control and protection of electrical equipment, and metering or real-time monitoring of electrical energy. Cable trays are an important accessory inside distribution cabinets.

[0003] Patent publication number CN217555443U discloses a wiring structure for a power distribution cabinet, including a power distribution cabinet body and a first fixing block and a second fixing block disposed on the left and right sides inside the power distribution cabinet body. The second fixing block is located above the first fixing block. The top end of the wiring drum is connected to the second fixing block through a rotating shaft. Wires are wound around the outer surface of the wiring drum. This utility model, through the first fixing block, the second fixing block, and the wiring drum, in conjunction with a locking block, a locking groove, and a return spring, allows the wires to be easily pulled when wiring is required, thereby driving the wiring drum to rotate. This allows the wires to be stably pulled by the operator, facilitating the wiring into the interior of the power distribution cabinet for connection. Furthermore, the wiring drum can be fixed to secure the wires. When there is excess wire, the wiring drum can be rotated to wind up the wires, thus preventing the wires inside the power distribution cabinet from becoming tangled.

[0004] The existing wiring structure of the distribution cabinet requires manual rotation of a crank to move a locking block and fix the wiring tube, thereby pulling the wire into the distribution cabinet. This manual operation is time-consuming and labor-intensive. Therefore, a wiring structure for the distribution cabinet is proposed, which uses a drive motor to drive a winding rod to rotate, winding the wire to its outside, thereby pulling the wire into the distribution cabinet, saving time and labor. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a cable pulling structure for a power distribution cabinet. By driving a motor to rotate a winding rod, the wire is wound around its outer side, thereby pulling the wire into the power distribution cabinet, saving time and effort.

[0006] The technical solution adopted by this utility model to solve its technical problem is a wiring structure for a power distribution cabinet, including a mounting base, a large belt pulley and a large gear. A side plate is welded to the top of the mounting base. A drive motor is mounted on one side of the side plate through a mounting bracket. A winding rod is rotatably connected to the side of the side plate away from the drive motor through a bearing. A limit component is provided on the side of the side plate located at the top of the winding rod.

[0007] The limiting assembly includes a structural frame fixed to one side of the side plate by bolts. A reciprocating lead screw is rotatably connected inside the structural frame via bearings. An internally threaded slider is sleeved on the outside of the reciprocating lead screw. A wire clamping assembly is provided on one side of the internally threaded slider. The wire clamping assembly includes a structural plate fixed to one side of the internally threaded slider by bolts. A connecting post is sleeved through the top of the structural plate. A retaining ring is fixed to the bottom of the connecting post by bolts. A connecting post is sleeved on the outside of the connecting post located between the structural plate and the retaining ring.

[0008] By adopting the above technical solution, the drive motor drives the winding rod to rotate and wind the wire. The compression spring pushes the wire, which is inserted into the retaining ring, to move down and stick to the outside of the winding rod. The reciprocating screw rotates and pushes the wire in the retaining ring to move back and forth through the internal threaded slider, so that it is evenly wound on the outside of the winding rod.

[0009] Specifically, a limiting groove is provided through the top of the structural frame, and a vertical rod is connected to the top of the internal threaded slider through a threaded groove. The structural block is fixed to the top of the vertical rod at the top of the limiting groove by bolts.

[0010] Specifically, the side plate has equidistant grooves on its outer side, the end of the winding rod located on the other side of the side plate is fixedly fitted with a large pulley, and the end of the side plate located on one side of the large pulley is fixedly fitted with a large gear.

[0011] Specifically, a small pulley is fixedly sleeved at the end of the reciprocating screw located on the other side of the side plate, and a belt is sleeved on the outside of the small pulley and the large pulley.

[0012] Specifically, a small gear is fixedly mounted on one side of the output shaft of the drive motor via a flat key, and the small gear meshes with the large gear.

[0013] Specifically, a sliding groove is provided on the inner side of the structural plate, a sliding strip is welded to one side of the connecting column, the sliding strip is located inside the sliding groove, and a limit block is fixed to the top of the connecting column at the top of the structural plate by bolts.

[0014] The beneficial effects of this utility model are:

[0015] (1) The wiring structure of the power distribution cabinet described in this utility model is to insert the wire into the retaining ring and wrap the wire around the outside of the winding rod. The drive motor is turned on to drive the winding rod to rotate through the small gear and the large gear. The rotation of the winding rod wraps the wire to its outside. The setting of the wire groove makes it easy for the wire to be wrapped to the outside of the winding rod.

[0016] (2) The wiring structure of the power distribution cabinet described in this utility model, when the drive motor drives the winding rod to rotate, the winding rod drives the reciprocating screw to rotate through the large belt pulley, the small belt pulley and the belt. The rotation of the reciprocating screw pushes the internal thread slider and the structural plate on one side to move back and forth. The reciprocating movement of the structural plate drives the retaining ring and the wire that is engaged to move back and forth through the connecting column, so that the wire can be evenly wound to the outside of the winding rod and will not be tangled together.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The winding rod is rotated by a drive motor, winding the wire to its outside, thus pulling the wire into the distribution cabinet, saving time and effort. Figure 1-4 As shown, the wiring structure of the power distribution cabinet of this utility model includes a mounting base 1, a large belt pulley 8 and a large gear 9. A side plate 2 is welded to the top of the mounting base 1. A drive motor 3 is mounted on one side of the side plate 2 through a mounting bracket. A winding rod 4 is rotatably connected to the side of the side plate 2 away from the drive motor 3 through a bearing. A limit component 5 is provided on the side of the side plate 2 located at the top of the winding rod 4.

[0025] The limiting component 5 includes a structural frame 501 fixed to one side of the side plate 2 by bolts. A reciprocating lead screw 502 is rotatably connected inside the structural frame 501 via bearings. An internally threaded slider 503 is sleeved on the outside of the reciprocating lead screw 502. A wire clamping component 6 is provided on one side of the internally threaded slider 503. The wire clamping component 6 includes a structural plate 601 fixed to one side of the internally threaded slider 503 by bolts. A connecting post 602 is sleeved through the top of the structural plate 601. A retaining ring 603 is fixed to the bottom of the connecting post 602 by bolts. The connecting post 602 is sleeved on the outside of the structural plate 601 and the retaining ring 603.

[0026] In use, the drive motor 3 drives the winding rod 4 to rotate and wind the wire. The compression spring 604 pushes the wire, which is inserted into the retaining ring 603, to move down and stick to the outside of the winding rod 4. The reciprocating screw 502 rotates and pushes the wire, which is inserted into the retaining ring 603, to move back and forth through the internal thread slider 503, so that it is evenly wound on the outside of the winding rod 4.

[0027] For example, such as Figure 3 As shown, the present invention also includes a limiting groove 505 extending through the top of the structural frame 501, a vertical rod 504 connected to the top of the internal threaded slider 503 via a threaded groove, and a structural block 506 fixed to the top of the vertical rod 504 at the top of the limiting groove 505 by bolts.

[0028] When in use, the vertical rod 504 slides within the limiting groove 505 as the internal thread slider 503 moves, which can prevent the internal thread slider 503 from rotating with the reciprocating screw 502 without affecting its movement.

[0029] For example, such as Figure 2 As shown, the present invention also includes: wire grooves 401 are provided at equal intervals on the outer side of the side plate 2; a large belt pulley 8 is fixedly sleeved on the end of the winding rod 4 located on the other side of the side plate 2; and a large gear 9 is fixedly sleeved on the end of the side plate 2 located on one side of the large belt pulley 8.

[0030] When in use, the opening of the wire groove 401 prevents the wires wound around the outside of the winding rod 4 from shifting.

[0031] For example, such as Figure 2 As shown, the present invention also includes a small belt pulley 10 fixedly sleeved at the end of the reciprocating screw 502 located on the other side of the side plate 2, and a belt 11 sleeved on the outer side of the small belt pulley 10 and the large belt pulley 8.

[0032] In use, the drive motor 3 drives the reciprocating screw 502 to rotate through the large pulley 8, the belt 11 and the small pulley 10.

[0033] For example, such as Figure 2As shown, the present invention also includes a small gear 7 fixedly sleeved on one side of the output shaft of the drive motor 3 by a flat key, wherein the small gear 7 meshes with the large gear 9.

[0034] In use, the drive motor 3 drives the winding rod 4 to rotate through the small gear 7 and the large gear 9.

[0035] For example, such as Figure 4 As shown, the present invention also includes a sliding groove 605 provided on the inner side of the structural plate 601, a sliding strip 606 welded to one side of the connecting column 602, the sliding strip 606 being located inside the sliding groove 605, and a limit block 607 being fixed to the top of the connecting column 602 at the top of the structural plate 601 by bolts.

[0036] When in use, the slider 606 slides in the groove 605 when the connecting column 602 moves up and down, which can prevent the connecting column 602 from rotating without affecting its up and down movement. The limit block 607 can prevent the connecting column 602 from falling out of the structural plate 601.

[0037] When using this utility model, personnel use bolts to fix the mounting base 1 to the inside of the power distribution cabinet, and use a power cord to connect the device to an external power source.

[0038] When it is necessary to pull the wire, the wire is inserted into the retaining ring 603 and the wire is wrapped around the outside of the winding rod 4. The drive motor 3 is turned on and the winding rod 4 is rotated through the small gear 7 and the large gear 9. The rotation of the winding rod 4 winds the wire around its outside. The wire groove 401 is designed to facilitate the wire being wound around the outside of the winding rod 4.

[0039] When the drive motor 3 drives the winding rod 4 to rotate, the winding rod 4 drives the reciprocating screw 502 to rotate through the large belt pulley 8, the small belt pulley 10 and the belt 11. The rotation of the reciprocating screw 502 pushes the internal thread slider 503 and the structural plate 601 on one side to move back and forth. The reciprocating movement of the structural plate 601 drives the retaining ring 603 and the locked wire to move back and forth through the connecting column 602, so that the wire can be evenly wound to the outside of the winding rod 4 and will not be tangled together.

[0040] The compression spring 604 pushes the retaining ring 603 downward, so that the wire engaged in the retaining ring 603 can be close to the outside of the winding rod 4. The internal thread slider 503 moves so that the upright rod 504 at its top slides in the limiting groove 505, which can prevent the internal thread slider 503 from rotating with the reciprocating screw 502 without affecting its movement.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
