Description

Technical Field

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

[0002] Switchgear is a crucial component in power distribution systems, primarily used for controlling and protecting power circuits. Common types of switchgear include circuit breakers, disconnectors, and load switches. Circuit breakers provide overload and short-circuit protection, automatically interrupting fault currents to ensure system safety. Disconnectors are used to isolate power during equipment maintenance, ensuring operator safety. Load switches are suitable for manually controlling circuit switching and are commonly used in low-current applications.

[0003] Existing technology discloses a switch installation structure for a power distribution cabinet, including a mounting plate inside the cabinet cavity and a locking block fixedly installed on the rear side of the switch. Two symmetrical hanging plates are fixedly connected to the cabinet cavity. The mounting plate is fixedly connected to the front of the hanging plates, and a screw is installed through the front of the hanging plates. By lifting the switch, the locking block enters the inner cavity of the mounting groove, causing rack two to engage with rack one, thus fixing the locking block in the inner cavity of the mounting plate. Positioning grooves and positioning blocks position the locking block, causing a limiting arc block to enter the inner cavity of the limiting arc groove, thus fixing the switch on the mounting plate. When the switch is damaged and needs to be disassembled, the switch is held by hand to unlock the engagement of rack two and rack one, allowing the locking block on the rear side of the switch to disengage from the inner cavity of the mounting groove. This allows for quick switch installation and independent replacement when damaged, improving the efficiency of power distribution cabinet switch maintenance.

[0004] The button for disconnecting the switch from the distribution box is located at the top of the switch, which is the wiring area. This means that the two may overlap in space, making it inconvenient to remove the switch from the distribution cabinet.

[0005] Based on this, the present invention designs a switch installation structure for a power distribution cabinet to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a switch installation structure for a power distribution cabinet.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A switch installation structure for a power distribution cabinet includes a cabinet and a control component installed inside the cabinet for controlling the opening and closing of the circuit. The cabinet includes an outer shell, and a crossbeam is installed inside the outer shell.

[0009] The control component includes a switch body, which has a slot, a base is detachably installed in the slot, and a press-lock part is installed on the base;

[0010] The press-locking part engages with the cavity of the switch body by pressing to connect the switch body and the base, and to disconnect the switch body from the base. The base has mounting holes. The press-locking part includes a multi-point guide component and an elastic follow-up locking component, which are respectively fixed in the mounting holes. The multi-point guide component guides the elastic follow-up locking component to connect with the switch body through a rotational snap-fit ​​component, thereby connecting the switch body and the base.

[0011] Preferably, the multi-point guiding component includes a first toothed disc, which is fixed in the mounting hole of the base, and a first ratchet is fixedly provided on the first toothed disc.

[0012] Preferably, the elastic follow-up locking assembly includes a second toothed disc, on which a second ratchet is mounted. The first ratchet and the second ratchet are centrally symmetrical, and the first and second ratchets guide the rotation of the rotary locking assembly.

[0013] Preferably, the rotary snap-fit ​​assembly includes a rotating cylinder rotatably mounted on the second gear plate, a baffle is fixedly mounted at one end of the rotating cylinder, and a spring is mounted at the other end of the rotating cylinder, the spring being located between the rotating cylinder and the first gear plate.

[0014] Preferably, a stop bar is installed on the outer wall of the rotating drum, and the stop bar moves along the second ratchet under the guidance of the first ratchet and pushes the rotating drum to rotate.

[0015] Preferably, the rotary snap-fit ​​assembly further includes a limiting plate installed in a slot on the switch body, the gap between the limiting plate and the outer wall of the switch body is a cavity, and the baffle is located in the cavity.

[0016] Preferably, the slot is provided with limiting grooves on both sides.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] In some embodiments, please refer to the accompanying drawings. Figure 1 A switch installation structure for a power distribution cabinet includes a cabinet 10 and a control component 20 installed inside the cabinet 10 for controlling the opening and closing of the circuit. The cabinet 10 is the outermost protective structure of the device, and the control component 20 is installed inside the protector.

[0031] Specifically, the housing 10 includes an outer shell 11, which is a rectangular box with the shape shown below. Figure 1 As shown, the interior has space for accommodating the control component 20, and a crossbeam 12 is fixedly mounted on the inner back wall of the housing 11. The crossbeam 12 is shaped as follows: Figure 1 As shown, it is strip-shaped with a C-shaped cross-section;

[0032] The control component 20 includes a switch body 21, which refers to a distribution box switch in the prior art, except that, as Figure 5 As shown, a slot 211 is installed on the switch body 21. The slot 211 is a rectangular groove located on the back of the switch body 21, which is recessed in the direction of the switch body 21. This position is the connection part with the base 22. The base 22 will be described in detail below. Two baffles 252 are vertically installed on both sides of the slot 211 of the switch body 21. There is a gap between the baffles 252 and the side wall of the switch body 21 at the slot 211, which is a cavity 213.

[0033] For example Figure 3 As shown in the diagram, the left side of the base 22 has a mounting buckle 222. The mounting buckle 222 refers to a groove that matches the crossbeam 12. The base 22 can be secured to the crossbeam 12 using the mounting buckle 222. It should be noted that this detachable connection between the mounting buckle 222 and the crossbeam 12 is existing technology and will not be elaborated upon here. On the other side of the base 22, a horizontal mounting hole 221 is opened on its side wall. The mounting hole 221 is used to adhesively fix the first gear plate 23 and the second gear plate 24. There is a certain distance between the first gear plate 23 and the second gear plate 24. The shapes of the first gear plate 23 and the second gear plate 24 are as follows... Figure 4As shown, the two are disc-shaped, with four first ratchet teeth 231 and two second ratchet teeth 241 welded and fixed to their side walls respectively. Both the first ratchet teeth 231 and the second ratchet teeth 241 are triangular with a certain curvature and are centrally symmetrically distributed. A rotating cylinder 25 passes through the center of the second ratchet disc 24. The rotating cylinder 25 is hollow, and a spring 253 is inserted into the hollow part. One end of the spring 253 is fixed to the closed inner wall of the left end of the rotating cylinder 25, and the other end abuts against the right side wall of the first ratchet disc 23. The outer wall of the rotating cylinder 25... Two stop rods 251 are fixed in symmetrical positions. The stop rods 251 are short cylinders. The rightmost part of the rotating cylinder 25 is a baffle 252 welded and fixed thereon. After pushing the baffle 252 to the left, the baffle 252 drives the rotating cylinder 25 to move to the left in sync. At the same time, the reaction thrust of the first geared disc 23 sealed at the bottom gives the spring 253 a push, compressing the spring 253. Meanwhile, the stop rods 251 also move to the left with the rotating cylinder 25. During this process, the inclined surface of the first ratchet 231 on the first geared disc 23 guides the stop rods 251 to move along its inclined surface. Figure 4 The middle stop lever 251 moves both to the left and upward. Therefore, the stop lever 251 pushes the rotating drum 25 to rotate, and the baffle 252 rotates with the rotating drum 25. The angle of each rotation is 90°. After the pressure on the baffle 252 is released, the rotating drum 25 returns to the outside of the second ratchet 241 of the second toothed disc 24 under the elastic force of the spring 253.

[0034] like Figure 3 , Figure 5 As shown, when the switch body 21 is installed on the base 22, the baffle 252 at the end of the rotating cylinder 25 of the base 22 passes through the gap between the two limiting plates 212 on the switch body 21 and enters the cavity 213. At this time, after pressing the switch body 21 once, the switch body 21 applies a pushing force to the baffle 252, and then the rotating cylinder 25 rotates. The rotating cylinder 25 simultaneously drives the baffle 252 to rotate 90°. At this time, the baffle 252 is perpendicular to the limiting plates 212. Based on this, the baffle 252 is stuck between the two limiting plates 212. At the same time, the base 22 also enters the slot 211 of the switch body 21, realizing the connection between the two. When the switch body 21 is pressed again, the rotating cylinder 25 and the baffle 252 rotate 90° again. At this time, the baffle 252 is parallel to the limiting plates 212, and the baffle 252 can be pulled out from between the limiting plates 212. The corresponding overall state of the device is: the switch body 21 is removed from the base 22.

[0035] By setting up components such as the rotating drum 25, pressure is applied to achieve the locking and unlocking effect of the switch body 21 on the base 22. Compared with the existing unlocking method by using a button, the pressing of this device does not affect the normal arrangement of the wires, and the operation is more convenient.

[0036] In some embodiments, please refer to the accompanying drawings. Figure 3 , Figure 5Limiting grooves 214 are installed on both sides of the slot 211 of the switch body 21. On the other hand, protruding plates 223 that are adapted to the limiting grooves 214 are installed on the base 22. When the switch body 21 is installed on the base 22, that is, after the base 22 is inserted into the slot 211 on the switch body 21, the protruding plates 223 on the base 22 enter the limiting grooves 214 on both sides of the switch body 21.

[0037] By setting the limiting groove 214 and the protrusion 223, the auxiliary switch body 21 is aligned when it is installed on the base 22, so that the rotating cylinder 25 and the baffle 252 on the base 22 can be accurately inserted into the cavity 213.

[0038] In some embodiments, please refer to the accompanying drawings. Figure 3 , Figure 5 The protruding plates 223 are located on both sides of the base 22, and the two protruding plates 223 have different thicknesses.

[0039] By setting two convex plates 223 of different thicknesses and corresponding limiting grooves 214 of different widths, it can not only help the staff to accurately center the switch body 21 and the base 22, but also prevent the switch body 21 from being installed backwards on the base 22 due to light or other reasons.

[0040] In some embodiments, please refer to the accompanying drawings. Figure 1 A vertical column 13 is installed inside the outer casing 11 and welded to the outer casing 11. Several small holes are equally spaced on the column 13. The crossbeam 12 is made of thin steel sheet and has a certain degree of elasticity. The width of the crossbeam 12 is slightly smaller than the width between the inner walls of the outer casing 11. At the same time, the two ends of the crossbeam 12 are connecting sections that are adapted to the small holes on the column 13. By slightly bending the crossbeam 12, the connecting sections at both ends are inserted into the small holes on the column 13 respectively. After releasing the crossbeam 12, it is reset, thereby realizing the detachable connection between the crossbeam 12 and the column 13. This facilitates changing the position of the crossbeam 12 on the column 13, thus enabling it to adapt to more specifications of switch bodies 21.

[0041] Working principle: When the switch body 21 is installed on the base 22, the baffle 252 at the end of the rotating cylinder 25 of the base 22 passes through the gap between the two limiting plates 212 on the switch body 21 and enters the cavity 213. At this time, after pressing the switch body 21 once, the switch body 21 applies a pushing force to the baffle 252, and then the rotating cylinder 25 rotates. The rotating cylinder 25 simultaneously drives the baffle 252 to rotate 90°. At this time, the baffle 252 is perpendicular to the limiting plates 212. Based on this, the baffle 252 is stuck between the two limiting plates 212. At the same time, the base 22 also enters the slot 211 of the switch body 21, realizing the connection between the two. When the switch body 21 is pressed again, the rotating cylinder 25 and the baffle 252 rotate 90° again. At this time, the baffle 252 is parallel to the limiting plates 212, and the baffle 252 can be pulled out from between the limiting plates 212. The corresponding overall state of the device is that the switch body 21 is removed from the base 22.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
