Description

Technical Field

[0001] This utility model relates to the field of central cabinet technology, and more specifically to a central cabinet with auxiliary support. Background Technology

[0002] A center-mounted switchgear, also known as a metal-armored center-mounted withdrawable switchgear, is a high-voltage power distribution device. It has a three-layer structure: the upper layer is the busbar and instrument room, the middle layer is the circuit breaker room, and the lower layer is the cable room.

[0003] Because the circuit breakers in the central switchgear are relatively heavy, a trolley is usually needed to transport them to the central switchgear during installation. During the installation process, the height of the circuit breaker and the intermediate layer of the central switchgear need to be adjusted to be level before installation. However, the heavy weight of the circuit breaker makes it difficult to align it with the intermediate layer, resulting in low installation efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a central cabinet with auxiliary support to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a centrally located cabinet with auxiliary support, comprising a cabinet body, the middle layer of the cabinet body being a placement cavity, a slide seat being slidably connected between the inner walls of the two sides of the placement cavity via a slide rail, a slide frame being provided inside the slide seat, and the slide frame being connected to the slide seat via a guide mechanism, a support frame being slidably connected between the inner walls of the two sides of the slide frame, a limiting component for fixing the position of the support frame being provided between the slide frame and the support frame, and a pressing component for fixing the slide frame being provided on one inner wall of the slide seat.

[0006] As a further embodiment of this utility model, the guiding mechanism includes two slide grooves, which are respectively opened between the inner walls of the two sides of the slide block. The outer walls of both sides of the slide block are welded with sliders, and the sliders slide in the slide grooves. The inner walls of both sides of the slide block are provided with a rotation groove and a limiting groove, and the rotation groove is connected to the limiting groove and the slide groove respectively.

[0007] As a further embodiment of this utility model, the limiting component includes a socket, which is opened on one side inner wall of the slide, and a pin is inserted into the socket. The inner walls on both sides of the support are provided with a first positioning hole and a second positioning hole, and one end of the pin is inserted into the second positioning hole.

[0008] As a further embodiment of this utility model, the extrusion assembly includes a rubber pad, which is adhered to the inner wall of one side of the slide and is in contact with the slide frame. The inner wall of one side of the slide is provided with a blocking assembly for auxiliary fixing of the support frame position.

[0009] As a further embodiment of this utility model, the blocking component includes a mounting groove, which is formed on the inner wall of one side of the slide. An elastic ball is bonded in the mounting groove. The outer wall of one side of the support frame has the same number of arc-shaped grooves as the mounting groove, and the elastic ball is located in the arc-shaped groove.

[0010] As a further embodiment of this invention, an inclined surface is provided on one side of the outer wall of the slide block for guiding the circuit breaker.

[0011] As a further embodiment of this utility model, one side of the cabinet is rotatably connected to a door panel via a hinge, and the door panel can completely cover the storage cavity.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5 This utility model provides a centrally located cabinet with auxiliary support, including a cabinet body 1. The middle layer of the cabinet body 1 is a placement cavity 2. A slide seat 4 is slidably connected between the inner walls of the two sides of the placement cavity 2 via a slide rail. A slide frame 7 is provided inside the slide seat 4, and the slide frame 7 is connected to the slide seat 4 via a guide mechanism. A support frame 8 is slidably connected between the inner walls of the two sides of the slide frame 7. A limiting component is provided between the slide frame 7 and the support frame 8 to fix the position of the support frame 8. A pressing component is provided on one inner wall of the slide seat 4 to fix the slide frame 7. In use, the slide seat 4 is pulled out from the placement cavity 2, and then one end of the slide frame 7 is moved to the other end of the slide seat 4, so that the slide frame 7 and the slide seat 4 are perpendicular. Then, the support bracket 8 is pulled out from the slide 7, so that one end of the support bracket 8 contacts the ground, and the position of the support bracket 8 is fixed by the limiting component, thereby supporting the slide 4. Then, the circuit breaker is placed on the slide 4, and the slide 4 and the circuit breaker are pushed into the cabinet 1 together. When it is pushed in halfway, the slide 7 and the support bracket 8 are put back in, so that the circuit breaker and the slide 4 are together in the cabinet 1. The slide 4, the slide 7, and the support bracket 8 form a support structure to support the circuit breaker. There is no need to align the circuit breaker during installation. At the same time, the circuit breaker can be adjusted on the slide 4, making it easier to put the circuit breaker into the cabinet 1, thereby improving the installation efficiency of the circuit breaker.

[0024] The guiding mechanism includes two slide grooves 14, which are respectively formed between the inner walls of the two sides of the slide block 4. Slider blocks 9 are welded to the outer walls of both sides of the slide frame 7, and the sliders 9 slide within the slide grooves 14. All four sides of the sliders 9 are curved surfaces, allowing them to rotate within the slide grooves 14. Rotation grooves 15 and limiting grooves 18 are formed on the inner walls of both sides of the slide block 4. The rotation grooves 15 are connected to the limiting grooves 18 and the slide grooves 14, respectively. The limiting grooves 18 and the sliders 9 can be completely fitted together, allowing the sliders 9 to move within the limiting grooves 15 and 14. Since the slide 7 cannot rotate within the slide block 4, as one end of the slide 7 moves to the other end of the slide block 4, the slide 7 is slightly rotated, causing the slider 9 to rotate slightly within the slide groove 14. This allows one end of the slide 7 to extend out from within the slide block 4. Then, the slide 7 is pulled to move the slider 9 within the slide groove 14, enabling the slider 9 to move into the rotation groove 15 and then into the limiting groove 18. This limits the angle of the slide 7, making it less prone to rotation and improving the support stability of the device.

[0025] The limiting component includes a socket 10, which is located on one inner wall of the slide 7. A pin 11 is inserted into the socket 10. The inner walls on both sides of the support 8 are provided with a first positioning hole 12 and a second positioning hole 13. One end of the pin 11 is inserted into the second positioning hole 13. When the support 8 needs to be slid out of the slide 7, the pin 11 is pulled to move one end of the pin 11 out of the second positioning hole 13, so that the support 8 can slide in the slide 7. When the first positioning hole 12 coincides with the socket 10, the pin 11 is inserted into the first positioning hole 12 to fix the support 8. At this time, the support 8 is in contact with the ground, thereby supporting the slide 4 and giving the slide 4 a stable support structure. At the same time, the support 8 can be stored, reducing the space occupied by the support structure.

[0026] The compression component includes a rubber pad 6, which is bonded to one inner wall of the slide block 4 and contacts the slide frame 7. One inner wall of the slide block 4 is provided with a blocking component to assist in fixing the position of the support frame 8. When the slide frame 7 is retracted, the slide frame 7 will first contact the rubber pad 6, and then the rubber pad 6 will be compressed and deformed. When the slide frame 7 is fully inserted into the slide block 4, the rubber pad 6 will rebound, thereby assisting in limiting the position of the slide frame 7 and improving the stability of the slide frame 7 after it is retracted.

[0027] The blocking component includes a mounting groove 16, which is formed on the inner wall of one side of the slide 4. An elastic ball 17 is bonded to the mounting groove 16. The outer wall of one side of the support frame 8 has the same number of arc-shaped grooves 19 as the mounting groove 16, and the elastic ball 17 is located in the arc-shaped groove 19. After the slide 7 is stored, the elastic ball 17 will enter the arc-shaped groove 19, thereby providing auxiliary fixation for the support frame 8 and further providing auxiliary fixation for the other end of the slide 7, which further improves the stability of the slide 7 after it is stored.

[0028] The slide 4 has an inclined surface 5 on one side of its outer wall to guide the circuit breaker, so that the circuit breaker can be easily placed on the slide 4. The cabinet 1 has a door panel 3 connected to one side by a hinge, and the door panel 3 can completely cover the placement cavity 2 to protect the circuit breaker.

[0029] The working principle of this utility model is as follows: In use, the slide block 4 is pulled out from the placement cavity 2, and then one end of the slide 7 is moved to the other end of the slide block 4. During the process of moving one end of the slide 7 to the other end of the slide block 4, the slide 7 is slightly rotated, causing the slider 9 to rotate slightly in the slide groove 14, thereby causing one end of the slide 7 to extend out from the slide block 4. Then, the slide 7 is pulled to move, causing the slider 9 to move in the slide groove 14, thereby allowing the slider 9 to move into the rotation groove 15, and then allowing the slider 9 to enter the limiting groove 18, thereby limiting the angle of the slide 7, making the slide 7 perpendicular to the slide block 4. Then, the support 8 is pulled out from the slide 7. The support frame 8 is brought into contact with the ground. The pin 11 is inserted into the first positioning hole 12 to fix the support frame 8, thereby supporting the slide 4. Then, the circuit breaker is placed on the slide 4, and the slide 4 and the circuit breaker are pushed into the cabinet 1 together. When it is pushed in halfway, the slide 7 and the support frame 8 are put away, so that the circuit breaker and the slide 4 are put into the cabinet 1 together. The slide 4, the slide 7, and the support frame 8 form a support structure to support the circuit breaker. There is no need to align the circuit breaker during installation. At the same time, the circuit breaker can be adjusted on the slide 4, making it easier to put the circuit breaker into the cabinet 1, thereby improving the installation efficiency of the circuit breaker.
