[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a grounding protection device for an electric power cabinet that is easy to install, comprising an electric power cabinet body 1, two groups of T-shaped plugs 101 are fixedly installed at the central position of one side of the inner bottom of the electric power cabinet body 1, a fixing socket 102 is provided at the top of the inner bottom of the electric power cabinet body 1 between the two groups of T-shaped plugs 101, and a positioning socket 103 is provided at the central position of one side of the inner bottom of the electric power cabinet body 1 away from the T-shaped plug 101. A positioning plug 302 is fixedly installed at one side of the bottom of the fixing frame 3 away from the T-shaped slot 301, and the positioning plug 302 corresponds to the positioning socket 103. Because the positioning socket 103 and the positioning plug 302 are provided, when the fixing frame 3 is clamped and fixed to the inner bottom of the electric power cabinet body 1, the positioning plug 302 is inserted into the corresponding positioning socket 103 to ensure that there is no misalignment when the fixing frame 3 is fixed to the inner bottom of the electric power cabinet body 1.

[0022] The card racks 2 are symmetrically fixedly installed on both sides of the bottom of the power cabinet body 1. A fixing rack 3 is provided at the central position between the two sets of card racks 2 at the bottom of the power cabinet body 1. Two sets of T-shaped slots 301 are symmetrically provided on one side of the fixing rack 3, and the T-shaped slots 301 correspond to the T-shaped plug-in blocks 101. Since the T-shaped plug-in blocks 101 and the T-shaped slots 301 are provided, the T-shaped slots 301 are clamped on the surface of the corresponding T-shaped plug-in blocks 101 to ensure that the fixing rack 3 is clamped on the bottom of the power cabinet body 1 and does not move at will.

[0023] A mounting block 4 is fixedly installed on one side of the top of the fixing frame 3, a mounting groove 401 is provided on one side inside the mounting block 4, and a slide groove 402 is provided at one end of the mounting groove 401, a fixed plug rod 403 is slidably installed inside the mounting groove 401, and both ends of the fixed plug rod 403 pass through the mounting groove 401, and the end of the fixed plug rod 403 away from the slide groove 402 corresponds to the fixed socket 102. Because of the fixed plug rod 403, after the fixed plug rod 403 extends out of the mounting block 4 and is inserted into the fixed socket 102, the fixing frame 3 and the mounting block 4 are clamped and fixed to the bottom of the power cabinet body 1 to ensure that the fixing frame 3 will not slide off the surface of the T-shaped plug block 101.

[0024] A limiting plate 404 is fixedly installed on the surface of the fixed rod 403 located inside the mounting groove 401 on one side away from the slide groove 402. A fixing spring 405 is provided on the surface of the fixed rod 403 located inside the mounting groove 401. One end of the fixed rod 403 passes through the mounting groove 401 and extends to the slide groove 402 where a shift block 406 is fixedly installed. By providing a fixing spring 405, the limiting plate 404 is pushed toward the end away from the slide groove 402 under the rebound action of the fixing spring 405, so that the fixed rod 403 can be pushed out of the mounting groove 401 and inserted into the fixed socket 102.

[0025] A clamping seat 5 is fixedly installed on one side of the mounting block 4 at the top of the fixing frame 3, and mounting grooves 501 are symmetrically arranged on both sides of the bottom of the clamping seat 5; a clamping rod 502 is slidably installed inside the mounting groove 501, and the bottom ends of the two sets of clamping rods 502 pass through the mounting groove 501 and are fixedly installed with a trapezoidal clamping block 505. Due to the presence of the trapezoidal clamping block 505, the grounding copper plate 6 is pushed to slide at the bottom of the trapezoidal clamping block 505, so that the grounding copper plate 6 contacts the inclined surface of the trapezoidal clamping block 505 to the top of the trapezoidal clamping block 505, so that the grounding copper plate 6 can pass over the trapezoidal clamping block 505 and be clamped inside the fixing frame 3;

[0026] The trapezoidal clamping block 505 is symmetrically provided with fixing bolts 506 on both sides, and the fixing bolts 506 pass through the trapezoidal clamping block 505 and are connected with the clamping seat 5. Since the fixing bolts 506 are provided, the fixing bolts 506 are tightened to fix the trapezoidal clamping block 505 at the bottom of the clamping seat 5, ensuring that the trapezoidal clamping block 505 will not move at will at the bottom of the clamping seat 5;

[0027] A limiting plate 503 is fixedly installed on the surface of the clamping rod 502 at the bottom of the mounting groove 501, and a clamping spring 504 is provided on the surface of the clamping rod 502 at the top of the limiting plate 503. A grounding copper plate 6 is provided inside the fixing frame 3 and on one side of the trapezoidal clamping block 505 between the two groups of clamping frames 2. By providing a clamping spring 504, the clamping rod 502 is pressed down under the rebound action of the clamping spring 504, so that the trapezoidal clamping block 505 can move down and clamp on one side of the grounding copper plate 6, thereby clamping and fixing the grounding copper plate 6.

[0028] Three groups of terminal posts 601 are symmetrically and equidistantly fixedly installed on both sides of the top of the grounding copper plate 6, and terminal nuts 602 are provided on the surfaces of the terminal posts 601. Limiting bars 603 are fixedly installed on both ends of the bottom of the grounding copper plate 6. Because of the limiting bars 603, the two ends of the grounding copper plate 6 are clamped into the interior of the card frame 2, so that the limiting bars 603 are clamped on the surface of the card frame 2, ensuring that the grounding copper plate 6 is clamped between the two groups of card frames 2 and will not move at will.

[0029] The working principle of the utility model is:

[0030] After pushing the shift block 406 to drive the fixed plug rod 403 to retract into the installation groove 401, the fixed frame 3 is correspondingly clamped on the surface of the two groups of T-shaped plug blocks 101 until the positioning plug block 302 is inserted into the positioning hole 103, the shift block 406 is released, and the fixed plug rod 403 is pushed out of the installation groove 401 and inserted into the fixed hole 102 under the rebound action of the fixing spring 405, and the fixing bolt 506 is loosened, and the grounding copper plate 6 is correspondingly clamped between the two groups of brackets 2, so that the central position of the grounding copper plate 6 is clamped between the fixed frame 3 and the trapezoidal clamp block 505, and the grounding copper plate 6 is pushed through the trapezoidal clamp block 505. The trapezoidal clamp block 505 is pressed down and clamped on one side of the grounding copper plate 6 under the rebound action of the clamping spring 504, so that the grounding copper plate 6 is clamped between the two groups of brackets 2 and located inside the fixed frame 3.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
