Description

Technical Field

[0001] This utility model relates to the field of power distribution technology, specifically to a withdrawable low-voltage switchgear. Background Technology

[0002] In modern power systems, withdrawable low-voltage switchgear is a crucial electrical device, widely used in low-voltage power distribution systems in industrial, commercial, and civil buildings. It is primarily used for receiving and distributing electrical energy, as well as controlling, protecting, and monitoring circuits. Withdrawable low-voltage switchgear offers significant advantages such as compact structure, convenient operation, and easy maintenance. Its drawer units can be flexibly pulled out and inserted, facilitating rapid replacement and repair of faulty units, thereby effectively improving the reliability and maintainability of the power supply system.

[0003] However, traditional withdrawable low-voltage switchgear mostly adopts a drawer-type unit design. To remove the existing drawers, one must first pull the drawer out of the switchgear, then pinch the elastic latches on both sides of the drawer to remove it. Because the space between the switchgear and the drawer sides is small, it is inconvenient to insert fingers and operate the drawer. Sometimes, the drawer is pulled out forcefully, which can easily damage the drawer and its internal components. Therefore, there is an urgent need to design a withdrawable low-voltage switchgear to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a withdrawable low-voltage switchgear to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A withdrawable low-voltage switchgear includes a cabinet box, the interior of which is provided with a plurality of drawer mechanisms, the drawer mechanisms being used to store at least components;

[0007] The drawer mechanism is fixedly connected to slide rail 1 on both sides, slide rail 2 is slidably connected to one side of slide rail 1, and slide rail mechanism is slidably connected to one side of slide rail 2. The slide rail mechanism is fixedly installed on both sides inside the cabinet. The slide rail 1, slide rail 2 and slide rail mechanism are at least used to pull the drawer mechanism out and push it in along the predetermined track.

[0008] The slide rail mechanism is at least used to eject the drawer mechanism when it is pulled out, and the slide rail mechanism is at least used to dampen the drawer mechanism when it is pushed in;

[0009] A slot mechanism is provided on one side of the slide rail one, and the slot mechanism is located between the slide rail one and the slide rail two. The slot mechanism is used at least for the disengagement of the drawer mechanism from the slide rail two.

[0010] Preferably, the drawer mechanism includes a panel, a handle is fixedly installed on one side of the panel, and a drawer box is fixedly installed on the other side of the panel.

[0011] Preferably, the slide rail mechanism includes a slide rail three, a sliding block is provided inside the slide rail three, a pin is fixedly installed on one side of the sliding block, a damping mechanism is provided inside the slide rail three, and a return spring is provided on both sides of the slide rail three.

[0012] Preferably, the damping mechanism includes a fixed block, which is fixedly installed on one side of the slide rail. Movable pins are respectively provided on both sides of the inside of the fixed block. A return spring is sleeved on the outer wall of the movable pin. A tube is fixedly installed on one side of the fixed block, and a pin block is fixedly installed on one end of the movable pin.

[0013] Preferably, the slot mechanism includes a connecting shaft, and the outer wall of the connecting shaft is fitted with a first limiting plate and a second limiting plate. A third return spring is provided between the first limiting plate and the second limiting plate, and a top pin is fixedly installed above the second limiting plate.

[0014] Preferably, a fixed shaft 1 and a fixed shaft 2 are fixedly connected to one side of the outer wall of the slide rail 1, and a handle 2 is provided on one side of the drawer mechanism. One end of the handle 2 is provided with a steel wire, and the other end of the steel wire is connected to the limiting plate 2.

[0015] In the above technical solution, the withdrawable low-voltage switchgear provided by this utility model has the following beneficial effects:

[0016] (1) When a complete overhaul is required, the drawer is separated by the slot mechanism. The second handle moves the wire rope, which in turn rotates the second limit plate downwards, causing the top pin to separate and the drawer mechanism to be removed as a whole. This design ensures both the safety of daily operation and the convenience of emergency maintenance.

[0017] (2) The maximum length of the drawer can be limited by the combined action of the three-section slide rail and the slot mechanism.

[0018] Damping structures are added at three points on the drawer slides. When the drawer is pushed in, it provides damping and can effectively slow down the pushing speed to avoid impact on internal components caused by pushing in too fast. When pulling out, the drawer can be popped out with a light push and then pulled out slowly. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-6As shown in the figure, an embodiment of the present invention provides a pull-out low-voltage switch cabinet, including a cabinet box 1. The cabinet box 1 is provided with a plurality of drawer mechanisms 2. The drawer mechanisms 2 are used to place components. Both sides of the drawer mechanism 2 are fixedly connected to slide rail 3. One side of slide rail 3 is slidably connected to slide rail 4. One side of slide rail 4 is slidably connected to slide rail mechanism 5. The slide rail mechanism 5 is fixedly installed on both sides of the inside of the cabinet box 1. The slide rail 3, slide rail 4 and slide rail mechanism 5 are used to pull out and push in the drawer mechanism 2 along a predetermined track. The slide rail mechanism 5 is used to pop out when the drawer mechanism 2 is pulled out and to dampen when the drawer mechanism 2 is pushed in. A slot mechanism 6 is provided on one side of slide rail 3. The slot mechanism 6 is located between slide rail 3 and slide rail 4. The slot mechanism 6 is used to disengage the drawer mechanism 2 from slide rail 4.

[0029] In this embodiment, a cabinet 1 is included, and the interior of the cabinet 1 is provided with a plurality of drawer mechanisms 2, which are at least used to place components;

[0030] Specifically, the drawer mechanism 2 includes a panel 21. A handle 22 is fixedly installed on one side of the panel 21, and a drawer box 23 is fixedly installed on the other side of the panel 21. The handle 22 is securely installed on one side of the panel 21, and the drawer box 23 is fixedly installed on the other side. The handle 22 is installed on the outside for easy pushing and pulling operation by the user; the drawer box 23 is installed on the inside for storing components.

[0031] In this embodiment, slide rail 3 is fixedly connected to both sides of drawer mechanism 2. Slide rail 4 is slidably connected to one side of slide rail 3, and slide rail mechanism 5 is slidably connected to one side of slide rail 4. Slide rail mechanism 5 is fixedly installed on both sides of the inside of cabinet 1. Slide rail 3, slide rail 4, and slide rail mechanism 5 are used at least to pull drawer mechanism 2 out and push it in along a predetermined track. Slide rail 4 is installed parallel to slide rail 3 to achieve smooth sliding. The sliding connection between slide rail 3 and slide rail 4 reduces the force required to pull the drawer. Slide rail mechanism 5 is installed on the inner wall of cabinet 1 and precisely aligned with the position of slide rail 4, allowing the drawer to be inserted and pulled out smoothly.

[0032] Specifically, the slide rail mechanism 5 includes slide rail three 51, inside which is a sliding block 52. A pin 53 is fixedly installed on one side of the sliding block 52. Inside the slide rail three 51, there is a damping mechanism 54. On both sides inside the slide rail three 51, there are reset springs 55. When the slide rail two 4 contacts the sliding block 52, it will drive the sliding block 52 to move and lock with the pin 53 to prevent the drawer from moving accidentally.

[0033] Specifically, the damping mechanism 54 includes a fixed block 541, which is fixedly installed on one side of the slide rail 51. Movable pins 542 are respectively provided on both sides of the fixed block 541. A return spring 544 is sleeved on the outer wall of the movable pin 542. A tube 543 is fixedly installed on one side of the fixed block 541. A pin block 545 is fixedly installed on one end of the movable pin 542. The return spring 55 is connected between the two ends of the slide rail 51 and the sliding block 52. When the external force is removed, it provides a restoring force to return the sliding block 52 to its initial position, so that the drawer mechanism 2 slowly pops out.

[0034] In this embodiment, a slot mechanism 6 is provided on one side of the slide rail 3. The slot mechanism 6 is located between the slide rail 3 and the slide rail 4. The slot mechanism 6 is used at least for the disengagement of the drawer mechanism 2 from the slide rail 4.

[0035] Specifically, the slot mechanism 6 includes a connecting shaft 61. The outer wall of the connecting shaft 61 is fitted with a first limiting plate 66 and a second limiting plate 67. A third return spring 69 is disposed between the first limiting plate 66 and the second limiting plate 67. A top pin 68 is fixedly installed above the second limiting plate 67. The third return spring 69 is placed in the space between the two limiting plates, providing a force to maintain their specific relative positions. The top pin 68 is vertically installed on the upper surface of the second limiting plate 67, protruding upwards. When pulled, it can separate the first slide rail 3 from the second slide rail 4. During installation, the first slide rail 3 and the second slide rail 4 are inserted parallel to each other. The top pin 68 moves downwards under pressure, entering the second slide rail 4. At this time, the second return spring 64 springs up, fixing it in place.

[0036] Specifically, a fixed shaft 62 and a fixed shaft 63 are fixedly connected to one side of the outer wall of slide rail 3. A handle 65 is provided on one side of the drawer mechanism 2. One end of the handle 65 is provided with a steel wire 64, and the other end of the steel wire 64 is connected to a limiting plate 67. The handle 65 is located on one side of the drawer mechanism 2, usually close to the panel 21, for easy access by the user. When the user pulls the handle 65, the steel wire 64 is pulled, which causes the limiting plate 67 to rotate around the connecting shaft 61, overcoming the force of the return spring 69, and finally triggering the function of the slot mechanism 6, so that slide rail 3 on the drawer mechanism 2 is disengaged from slide rail 4.

[0037] Working steps: 1. When it is necessary to open, push the drawer mechanism 2 with force. The damping mechanism 54 set inside the slide rail mechanism 5 will separate from the latch 53, so that the drawer mechanism 2 will slowly pop out. At this time, the user only needs to slowly pull it out.

[0038] 2. When it is necessary to remove it completely, simply pull the slot mechanism 6 to disengage it from the slide rail 2 4 to remove it completely.

[0039] 3. After the maintenance is completed, simply align slide rail 1 3 and slide rail 2 4 and push them flat. The slot mechanism 6 will directly engage with the slot of slide rail 2 4.

[0040] Fourth, push the drawer mechanism 2. At this time, the slide rail 2 4 will move closer to the slide rail mechanism, pushing the damping mechanism to connect with the latch.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
