Description

Technical Field

[0001] This utility model relates to the field of electrical switches, and in particular to a fast-acting switch switching mechanism. Background Technology

[0002] In numerous industrial, power, and specialized equipment applications, electrical switches, as key components of circuit control, directly impact the stable operation of the entire system through their performance and safety. Especially in special environments, such as high-voltage, high-current power transmission and distribution systems, and industrial equipment that frequently performs circuit switching operations, even more stringent requirements are placed on switch performance. When a switch breaks a circuit, an electric arc is generated between the contacts. This arc not only generates high temperatures, causing erosion of the switch contacts and shortening its lifespan, but also, with the continuous development of industrial technology, the functions of electrical equipment are becoming increasingly complex, placing higher demands on the number and flexibility of switch port connections. In some large equipment or complex circuit systems, it is necessary to flexibly increase or decrease the number of switch connection ports according to actual needs to achieve the connection and control of different circuits. Conventional switches, lacking effective arc-extinguishing devices and with relatively fixed structures, have their port numbers determined at the initial design stage.

[0003] The existing technical solutions described above have the following drawbacks: there is no way to quickly disconnect the connection structure; during rapid disconnection, electric arcs are easily generated and cannot be eliminated; and the connection ports of the switch are fixed, making it impossible to add more connection ports. Utility Model Content

[0004] The purpose of this invention is to provide a fast-acting switch mechanism to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fast-acting switch switching mechanism, comprising:

[0007] The outer shell is provided in multiple ways. Each of the multiple outer shells has a first mounting hole that runs through the front and back. The outer shell is hollow. The outer shell has a second mounting hole that runs through the left and right sides. The left end of the outer shell has a buckle. The right end of the outer shell has a locking block. The top of the locking block has a connecting hole that runs through the top and bottom. The connecting hole cooperates with the buckle. The multiple outer shells are connected from left to right through the locking block and the buckle.

[0008] Handle, the handle being used to turn the isolating switch on / off;

[0009] An operating insulator is fixedly connected to the left end of the housing. The top of the operating insulator has a straight hole that runs vertically through it. The handle is rotatably mounted on the top of the operating insulator. The right side of the operating insulator has a through hole that runs horizontally through it. The right side and front side of the top of the operating insulator have locking holes.

[0010] The first connecting rod is rotatably mounted in the through hole, and the right end of the first connecting rod is provided with a first keyhole;

[0011] The second link passes through the second mounting hole and has a third mounting hole that extends vertically. The left and right ends of the second link are provided with second key holes. The first link and the second link are fixedly connected through the first key hole and the second key hole.

[0012] A moving contact head, wherein the moving contact head passes through the third mounting hole;

[0013] A stationary contact head is fixedly installed in the first mounting hole of the housing, and the stationary contact head is matched with the moving contact head;

[0014] An arc-extinguishing device is provided, which is fixedly installed on the top of the stationary contact head and is used to extinguish an arc.

[0015] By adopting the above technical solution, rotating the handle drives the first connecting rod to rotate, which in turn drives the second connecting rod to rotate, causing the moving contact head located on the second connecting rod to rotate as well. This allows for rapid connection or disconnection with the stationary contact head, and the arc generated by the rapid disconnection is extinguished by an arc-extinguishing device. The left and right ends of the second connecting rod are each provided with a second keyhole, through which keys are installed to connect multiple second connecting rods. The left end of the housing is provided with a latch, and the right end with a locking block. The latches and locking blocks can be interconnected to increase the number of housings, thereby increasing the number of moving and stationary contact heads.

[0016] In a further embodiment, the operational insulator includes:

[0017] A housing, wherein the housing is hollow;

[0018] A joystick, wherein multiple joysticks are provided and symmetrically arranged on the left and right sides inside the housing, and a spring is sleeved on the joystick;

[0019] The disks are provided in multiple ways. The disks are rotatably connected to the ends of the rocker arm that are close to each other. The disks are rotatably connected to the center of the housing. The end of the disk near the through hole is fixedly connected to the first connecting rod.

[0021] The first gear is located at the inner top of the housing and is rotatably connected to the handle;

[0022] The second gear is located at the bottom end of the first gear and meshes with the first gear and the rack.

[0023] By adopting the above technical solution, rotating the handle drives the first gear connected to the handle to rotate. Since the second gear is fixedly connected to the first gear and the rack, the second gear rotates, thereby causing the rack to move. The rack is fixedly connected to the connecting plate. The connecting plate moves, and the protrusion at the bottom of the connecting plate contacts the disk, pushing the disk to rotate. The disk is fixedly connected to the first connecting rod, causing the first connecting rod to rotate.

[0024] In a further embodiment, the moving contact head includes:

[0025] Pressure plates are symmetrically arranged in the third mounting holes;

[0026] The contact plates are symmetrically arranged on the left and right sides of the pressure plate, and a plurality of protrusions are provided on the left and right sides of the contact plates, which are located at the top and bottom ends of the contact plates.

[0027] In a further embodiment, the stationary contact head includes:

[0028] A conductive plate, wherein the conductive plate is fixedly connected to the first mounting hole of the outer casing;

[0029] A guide block is fixedly installed on the top of the conductive plate, and the gap between the guide block and the contact plate is matched.

[0030] In a further embodiment, the arc-extinguishing device includes:

[0031] An arc-extinguishing chamber, wherein the end of the arc-extinguishing chamber near the moving contact head is completely open, and the arc-extinguishing chamber is fixedly connected to the top of the stationary contact head;

[0032] An electromagnetic coil is fixedly connected inside the arc-extinguishing chamber and electrically connected to a power source. The electromagnetic coil is used to attract an electric arc.

[0033] The system includes multiple arc-extinguishing grids, which are spaced apart from top to bottom inside the arc-extinguishing chamber. The arc-extinguishing grids are located on the open side of the electromagnetic coil and are used to divide the electric arc.

[0034] In a further embodiment, a protective shell is also included, which is fixedly connected to the rear side of the outer shell. The protective shell has a through-hole on the side away from the outer shell, and the protective shell is used to prevent electric shock.

[0035] In a further embodiment, a fourth mounting hole is provided at the center of the handle, and a locking block is provided in the fourth mounting hole, the locking block being rotatably connected to the handle.

[0036] In summary, this utility model has the following beneficial effects:

[0037] 1. The design, in which the handle is fixedly connected to the first gear and the second gear meshes with the first gear and the rack, enables the first gear to rotate when the handle is rotated, which in turn drives the second gear to rotate, causing the rack to move. This converts the rotation of the handle into the movement of the rack. Attached Figure Description

A connecting plate 54 is fixedly connected to the bottom of the rack 55 and moves with it. A protrusion is provided at the bottom of the rack 55, which engages with a groove in the disc 53, causing the protrusion to push the disc 53 to rotate, thus moving the rocker arm 52 in the opposite direction.

[0056] When the switch needs to be turned off, the first gear 56 rotates when the handle 4 is reset, causing the second gear 57 to rotate as well. The second gear 57 drives the rack 55 to move, causing the connecting plate 54 to move. The spring sleeved on the rocker arm 52 pushes the disc 53 to rotate, causing the disc 53 to reset.

The electric arc is attracted to the arc extinguishing grid plate 103 by the electromagnetic coil 102. The multiple arc extinguishing grid plates 103 divide the electric arc into multiple segments, so that the total voltage drop exceeds the system voltage, forcing the electric arc to extinguish.
