[0003] There are many types of high and low voltage equipment. Low voltage equipment includes low voltage circuit breakers and transformers, while high voltage equipment includes high voltage fuses and high voltage disconnect switches. Most of these devices need to be installed inside switchgear. Currently, high and low voltage equipment is usually fixed with bolts during installation. Workers have to hold an electric drill in one hand and support the high and low voltage equipment with the other to carry out the installation work, which is quite cumbersome. Especially when installing circuit breakers, because there are many of them, workers need to use a lot of bolts to fix them, which makes the entire installation process time-consuming, reduces the installation efficiency of high and low voltage equipment, and is not conducive to its use. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick locking assembly mechanism for high and low voltage equipment to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a quick-locking assembly mechanism for high and low voltage equipment, comprising a cabinet, a positioning component, and a locking component.

[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model, by providing a positioning component, can position the circuit breaker to the front of the mounting plate. By rotating the screw, the screw and threaded sleeve control the downward movement of the extrusion roller. After the extrusion roller moves, it extrudes the inclined surface of the trapezoidal block. After the trapezoidal block is extruded, it drives the positioning frame to move backward, adjusting the mounting plate and positioning frame to the required distance. The circuit breakers are then placed between the mounting plate and the positioning frame in sequence and arranged neatly. Then, the screw is rotated again to clamp the circuit breaker with the positioning frame. No manual support from the operator is required, making it convenient to fix the circuit breaker.
[0015] 2. This utility model, by providing a locking assembly, can lock and fix multiple circuit breakers through a locking frame. The locking frame is inserted into the locking box, and the locking teeth press against the ratchet plate, causing it to move and compress the elastic plate until the locking frame locks the circuit breaker. At this time, the elastic plate resets and controls the ratchet plate to engage with the locking teeth, thereby realizing the locking and fixing of the circuit breaker. The operation is quick and convenient, improving its installation efficiency. Attached Figure Description

Detailed Implementation
[0024] 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. The high and low voltage equipment quick locking assembly mechanism involved in 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.
[0025] This utility model provides a quick-locking assembly mechanism for high and low voltage equipment, including a cabinet 100, a positioning component 200, and a locking component 300. A cabinet door 110 is hinged to the left front side of the cabinet 100. A mounting plate 120 is fixedly connected between the two sides of the inner cavity of the cabinet 100. A circuit breaker 130 is installed on the front side of the mounting plate 120. The positioning component 200 includes a fixing plate 210, the front side of which is fixedly connected to the mounting plate 120. A screw is movably connected to the bottom of the fixing plate 210. The screw 220 has a threaded sleeve 230 threadedly connected to its surface. Both sides of the threaded sleeve 230 are movably connected to compression rollers 240. A positioning frame 250 is provided on the rear side of the screw 220. The front side of the positioning frame 250 extends to the front side of the mounting plate 120. Trapezoidal blocks 260 are fixedly connected to both sides of the top rear side of the positioning frame 250. Tension springs 270 are fixedly connected to both sides of the bottom side of the positioning frame 250. The locking assembly 300 includes two locking boxes 310. The front side of the locking box 310 is connected to the mounting plate 120. The locking box 310 has a fixed connection. A ratchet plate 320 is provided inside the locking box 310. Elastic pieces 330 are fixedly connected to opposite sides of both ratchet plates 320. A locking frame 340 is provided on the top front side of the circuit breaker 130. Both rear sides of the locking frame 340 extend into the inner cavity of the locking box 310. Locking teeth 350 are fixedly connected to the rear sides of both sides of the locking frame 340. Opposite sides of the two locking teeth 350 engage with the ratchet plate 320. The mounting plate 120 facilitates the positioning and installation of the circuit breaker 130. The fixing plate 210 facilitates the installation and use of the screw 220. The threaded sleeve 230 can cooperate with the screw 220 to control the movement of the two pressing rollers 240. The pressing rollers 240 can press against the inclined surface of the trapezoidal block 260, thereby controlling the movement of the positioning frame 250. The tension spring 270 can reset the positioning frame 250 when the trapezoidal block 260 is not pressed. The ratchet plate 320 can cooperate with the elastic plate 330 to engage with the locking teeth 350. The locking frame 340 can lock and fix the circuit breaker 130.
[0026] Furthermore, a knob 280 is fixedly connected to the bottom of the screw 220. The surface of the knob 280 is covered with an insulating anti-slip sleeve. The knob 280 allows the operator to easily rotate the screw 220, and the insulating anti-slip sleeve protects the knob 280 and increases its anti-slip effect.
[0027] Furthermore, the two sides of the threaded sleeve 230 are movably connected to the extrusion roller 240 via bearings, and the front side of the tension spring 270 is fixedly connected to the mounting plate 120. The bearings can increase the stability of the extrusion roller 240 when rotating, and the tension spring 270 can reset the positioning frame 250.
[0028] Furthermore, a slider 140 is movably connected to the side of the extrusion roller 240 away from the threaded sleeve 230. Both sides of the rear side of the mounting plate 120 are provided with slide grooves 150 that cooperate with the slider 140. The slider 140 and the slide grooves 150 can limit the extrusion roller 240 so that it can move up and down smoothly.
[0029] Furthermore, the top and bottom sides of the front side of the mounting plate 120 are respectively provided with movable openings that cooperate with the positioning frame 250 and the locking frame 340. A heat dissipation vent is provided at the bottom left side of the cabinet door 110. The movable openings facilitate the forward and backward movement of the positioning frame 250 and the locking frame 340, and the heat dissipation vent facilitates the heat dissipation of the cabinet 100.
[0030] Furthermore, a push plate 360 is fixedly connected to the top of the ratchet plate 320. The top of the push plate 360 extends to the outside of the locking box 310. The push plate 360 allows the operator to easily push the ratchet plate 320 so that it does not engage with the locking teeth 350.
[0031] Furthermore, the top of the locking box 310 has an movable notch for use with the push plate 360. Magnets are fixedly connected to the opposite sides of the two push plates 360. The movable notch facilitates the use of the push plate 360, and the magnets can fit against the inner wall of the cabinet 100.
[0032] Furthermore, the two sides of the elastic plate 330 are fixedly connected to the inner walls of the ratchet plate 320 and the locking box 310, respectively. The front side of the locking box 310 is provided with a through hole that cooperates with the locking frame 340. The elastic plate 330 can control the ratchet plate 320 to engage with the locking tooth 350, and the through hole can facilitate the use of the locking frame 340.
[0033] The working principle of this utility model is as follows: Rotating knob 280 causes knob 280, in conjunction with screw 220, to move threaded sleeve 230 and pressing roller 240 downwards. Pressing roller 240 moves and presses the inclined surface of trapezoidal block 260, causing trapezoidal block 260 to control positioning frame 250 to move backwards. This changes the distance between positioning frame 250 and mounting plate 120. After adjusting the distance between positioning frame 250 and mounting plate 120 to allow placement of circuit breaker 130, circuit breaker 130 is placed between mounting plate 120 and positioning frame 250, and the circuit breakers 130 are neatly arranged. Then, knob 280 is rotated again to adjust the positioning... The frame 250 clamps and fixes the circuit breaker 130. The locking frame 340 is inserted into the inner cavity of the locking box 310, so that the locking teeth 350 continuously press against the ratchet plate 320 until the locking frame 340 locks and fixes the circuit breaker 130. At the same time, the elastic plate 330 resets and drives the ratchet plate 320 to move. The ratchet plate 320 moves and engages with the locking teeth 350, thereby locking and fixing the circuit breaker 130 using the locking frame 340. Since the circuit breaker 130 is locked and fixed by the locking frame 340 and the positioning frame 250, no bolts are needed, so that the entire installation process can be completed quickly and its installation efficiency can be improved.
