Description

Technical Field

[0001] The utility model belongs to the field of distribution cabinets, and particularly relates to a distribution cabinet with a movable wire harness fixing structure. Background Technique

[0002] The distribution cabinet is an indispensable device in the power system, mainly used for receiving, distributing, and controlling electric energy. Its basic principle is to connect the external power supply to the bus through the incoming line switch, and then distribute the power from the bus to each outgoing line switch. At the same time, protection electrical appliances and measuring instruments are equipped to ensure the safe operation of the power system. The fixing structure of the wire harness inside the distribution cabinet is crucial for ensuring electrical safety and the stable operation of the equipment. During the actual use of the distribution cabinet, components are usually fixed inside the cabinet, and then the wires of each component are led out and wired. The structures of the distribution cabinets used in the market are relatively simple, and most of them only fix the wire harness by winding. For example, when wiring, straps are generally used for fixing or the wire harness is fixed by screwing a locking hoop, etc. Although the wire harness can be fixed, these methods are relatively cumbersome to operate. In addition, it is not convenient to quickly fix or extract the wire harness. At the same time, when it is necessary to adjust the position of the fixing structure according to the height of the wire harness, the conventional fixing structure performs poorly and it is not convenient to flexibly adjust the fixing position of the wire harness in the distribution cabinet. Therefore, a new structure is needed to solve the above technical problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a distribution cabinet with a movable wire harness fixing structure to solve the problems raised in the above background technique.

[0004] The utility model is realized through the following technical solutions: A distribution cabinet with a movable wire harness fixing structure, including: a cabinet body, a bracket, and a wire harness bundling component. A device cavity is recessed on the front surface of the cabinet body, and multiple groups of mounting brackets are installed on the rear surface of the device cavity. Brackets are installed on both the front and rear surfaces of the device cavity. A square groove and a sliding groove that are connected are recessed leftward on the right surface of the bracket, and a wire harness bundling component is arranged in the square groove;

[0005] The wire harness bundling component includes a first square plate and a second square plate. The first square plate and the second square plate are connected by multiple groups of second springs. The right end of the second square plate is connected to a wire harness frame through a square rod. Two groups of door panels are symmetrically installed on the right side of the wire harness frame. A clamping plate is arranged inside the wire harness frame. The left end of the clamping plate is connected to a second spring. A push plate is installed on each of the upper and lower sides of the right surface of the first square plate. The right end of the push plate penetrates through the second square plate, the wire harness frame, and the clamping plate and is connected to the surface of the door panel.

[0006] As a preferred embodiment, a square groove is recessed leftward on the lower side of the right surface of the bracket, and a sliding groove with the same depth and width as the square groove is recessed upward at the top of the square groove;

[0007] On the front and rear surfaces on the left side inside the sliding groove, two groups of first baffles are symmetrically installed. On the front and rear surfaces on the right side inside the sliding groove, two groups of second baffles are symmetrically installed. The distance between the left side inside the sliding groove and the first baffle is greater than the thickness of the first square plate. The setting of the first baffle enables the first square plate to fit and move up and down between the left surface of the sliding groove and the first baffle. The first baffle cooperates with the second baffle to prevent the first square plate and the second square plate from detaching from the sliding groove.

[0008] As a preferred embodiment, the width and height of the square groove match the width and height of the first square plate and the second square plate, and the first square plate and the second square plate are inserted into the square groove; after the first square plate and the second square plate extend into the square groove, they can slide upward into the sliding groove.

[0009] As a preferred embodiment, the distance between the two groups of second baffles is greater than the width of the square rod. The front and rear sides of the left surface of the second baffle and the right surface of the second square plate are both formed with a frosted surface by laying metal particles. The formation of the frosted surface can reduce the probability of the second square plate sliding in the sliding groove under non-artificial force application.

[0010] As a preferred embodiment, the cross-section of the wire harness holder is U-shaped. Cut grooves are formed on both the upper and lower sides at the right end of the wire harness holder. The cut grooves are movably connected to the door panel through a rotating shaft, and two groups of ear plates are symmetrically fixed on the right side of the upper and lower surfaces of the wire harness holder.

[0011] As a preferred embodiment, a groove is formed by the left surface at the center position inside the left wall of the wire harness holder recessing leftward into the square rod. The left end of the second spring is connected to the left side inside the groove. The groove cooperates with the second spring

[0012] As a preferred embodiment, the second square plate, the wire harness holder, and the clamping plate are all formed with two groups of symmetric rectangular holes through the left and right surfaces. The right end of the push plate penetrates the second square plate, the wire harness holder, and the clamping plate through the rectangular hole and is connected to the left surface of the door panel through a pull rope.

[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: The opening of the square groove and the sliding groove enables the wire harness assembly to be inserted into the square groove and then pushed into the sliding groove, realizing the installation of the wire harness assembly, and facilitating flexible up and down movement, which is convenient for clamping and fixing wire harnesses at different heights. By connecting the push plate to the right side of the first square plate, and the right end of the push plate sequentially penetrates the second square plate, the wire harness holder, and the clamping plate and is connected to the left side of the door panel. When the wire harness holder is pushed towards the first square plate, the wire harness holder pulls the door panel to move and collide with the push plate, and the push plate pushes the door panel to rotate around one side of the wire harness holder, forming an opening between the two door panels, so that the wire harness can be quickly placed inside the wire harness holder, and the clamping plate and the door panel clamp and fix the wire harness.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a distribution cabinet with a mobile wire harness fixing structure, including: a cabinet body 100, a bracket 200 and a wire harness assembly 300. A device cavity 110 is formed by the depression on the front surface of the cabinet body 100. A plurality of mounting brackets 120 are installed on the rear surface of the device cavity 110. Brackets 200 are installed on both the front and rear surfaces of the device cavity 110. A square groove 210 and a sliding groove 220 that communicate with each other are formed by the leftward depression on the right surface of the bracket 200. A wire harness assembly 300 is provided in the square groove 210;

[0024] The wire harness assembly 300 includes a first square plate 310 and a second square plate 330. The first square plate 310 and the second square plate 330 are connected by a plurality of second springs 380. The right end of the second square plate 330 is connected to a wire harness holder 350 through a square rod 340. Two door panels 360 are symmetrically installed on the right side of the wire harness holder 350. A clamping plate 370 is provided in the wire harness holder 350. The left end of the clamping plate 370 is connected to a second spring 380. A set of push plates 390 are installed on both the upper and lower sides of the right surface of the first square plate 310. The right end of the push plate 390 penetrates through the second square plate 330, the wire harness holder 350 and the clamping plate 370 and is then connected to the surface of the door panel 360.

[0025] Please refer to Figures 2 to 4 , a square groove 210 is formed by the leftward depression on the lower side of the right surface of the bracket 200. A sliding groove 220 with the same depth and width as the square groove 210 is formed by the upward depression on the top of the square groove 210.

[0026] Two groups of first baffles 230 are symmetrically installed on the front and rear surfaces on the left side inside the sliding groove 220. Two groups of second baffles 240 are symmetrically installed on the front and rear surfaces on the right side inside the sliding groove 220. The distance between the left side inside the sliding groove 220 and the first baffle 230 is greater than the thickness of the first square plate 310. The setting of the first baffle 230 enables the first square plate 310 to move up and down between the left surface of the sliding groove 220 and the first baffle 230. The first baffle 230 and the second baffle 240 cooperate to prevent the first square plate 310 and the second square plate 330 from detaching from the sliding groove 220.

[0027] The width and height of the square groove 210 match the width and height of the first square plate 310 and the second square plate 330. When the first square plate 310 and the second square plate 330 are inserted into the square groove 210, the first square plate 310 and the second square plate 330 can slide upward into the sliding groove 220 after extending into the square groove 210.

[0028] The distance between the two groups of second baffles 240 is greater than the width of the square rod 340. The left surface of the second baffle 240 and the front and rear sides of the right surface of the second square plate 330 are both provided with a frosted surface by laying metal particles. The formation of the frosted surface can prevent the second square plate 330 from sliding on the surface of the second square plate 330 without artificial force application.

[0029] As the first embodiment of the present utility model, during actual use, when it is necessary to fix the wire harness led out by the components fixed on the mounting bracket 120, first, the upper bracket 200 is installed at a suitable position on the inner wall of the equipment cavity 110 through screws. Then, the wire harness assembly 300 is inserted into the square groove 210. Since the surfaces of the second baffle 240 and the second square plate 330 are both covered with metal particles to form a frosted surface, there is resistance when the second baffle 240 moves upward. At this time, the wire harness holder 350 is pressed towards the upper bracket 200, and the second spring 380 deforms and compresses. The second square plate 330 is pulled to move towards the first square plate 310. At this time, the position of the second square plate 330 is behind the second baffle 240. Then, while maintaining the pressure on the upper bracket 200, the wire harness holder 350 is pushed upward at the same time, enabling the first square plate 310 and the second square plate 330 to fit and move in the sliding groove 220. When the wire harness holder 350 moves to the position of the wire harness, the force applied to the wire harness holder 350 is cancelled, and the first spring 320 can reset, thereby pushing the second square plate 330 to stick to the second baffle 240, realizing the installation of the wire harness holder 350, and being convenient for flexible up and down movement, facilitating the clamping and fixing of wire harnesses at different heights, and multiple groups of wire harness assemblies 300 can be installed according to the above steps.

[0030] Meanwhile, when the length of the upper bracket 200 is appropriate, the upper bracket 200 can be horizontally installed inside the equipment cavity 110. Due to the square structures of the first square plate 310 and the second square plate 330, it is convenient to adjust the angles of the first square plate 310 and the second square plate 330 and then insert them into the square groove 210, facilitating the fixing of horizontal or vertical wire harnesses inside the equipment cavity 110, and realizing the flexible use of the wire harness holder 350.

[0031] Please refer to Figure 3 and Figure 4 , the cross-section of the wire harness holder 350 is U-shaped. Cutting grooves are formed on both the upper and lower sides at the right end of the wire harness holder 350. The cutting grooves are movably connected to the door panel 360 through rotating shafts. Two groups of ear plates are symmetrically fixed on the upper and lower surfaces on the right side of the wire harness holder 350.

[0032] The center position on the left side surface of the inner wall of the wire harness holder 350 is recessed leftward into the square rod 340 to form a groove. The left end of the second spring 380 is connected to the left side inside the groove.

[0033] Two groups of symmetric rectangular holes are formed through the left and right surfaces of the second square plate 330, the wire harness holder 350, and the clamping plate 370. The right end of the push plate 390 penetrates through the second square plate 330, the wire harness holder 350, and the clamping plate 370 through the rectangular holes and is connected to the left surface of the door panel 360 through a pull rope. The function of the pull rope is to connect the push plate 390 and the door panel 360, and can pull the door panel 360 to close.

[0034] As the second embodiment of the present utility model, after extending the wire harness led out by the components on the mounting bracket 120 outward, after moving the corresponding wire harness assembly 300 to an appropriate height according to the above steps, by pushing the ear plates at both ends of the wire harness bracket 350, the wire harness bracket 350 can be moved towards the bracket 200. Since the right end of the push plate 390 penetrates through the square plate two 330, the wire harness bracket 350 and the clamping plate 370 through the rectangular hole and is connected to the left surface of the door panel 360 through the pull rope, the position of the push plate 390 remains unchanged during the movement of the wire harness bracket 350. When the wire harness bracket 350 moves towards the push plate 390, the top of the push plate 390 collides with the door panel 360, and the door panel 360 rotates around one side of the wire harness bracket 350 under the action of the rotating shaft. At this time, an opening is formed between the two groups of door panels 360, so that the wire harness can be placed inside the wire harness bracket 350. At the same time, the spring two 380 pushes the clamping plate 370 to move towards the position of the wire harness, which can realize the quick clamping and fixing of the wire harness and facilitate the extraction of the wire harness from the wire harness bracket 350.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
