DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model with specific embodiments in conjunction with the accompanying drawings. Refer to Figures 1-4 :

[0022] A waterproof panel of a circuit breaker with a locking function, including a base 1 that fits with the installation plane. A window for installing the circuit breaker 2 is provided inside the base 1. A flip-up window cover 3 is hinged on the base 1. The base 1 and the window cover 3 are locked by a tongue lock 4. When the window cover 3 is closed, an isolated circuit breaker compartment and a lock compartment 6 are formed between the window cover 3 and the base 1. The window is correspondingly arranged with the circuit breaker compartment, and the tongue lock 4 is correspondingly arranged with the lock compartment 6. A counterbore for fixing the lock body 7 of the tongue lock 4 is provided on the window cover 3. An upward-opening locking groove 8 is provided on the base 1. The lock tongue 9 of the tongue lock 4 cooperates with the locking groove 8 for locking. Further, the width of the locking groove 8 is greater than the width of the lock tongue 9. In the locked state, the lock tongue 9 cooperates with one side of the locking groove 8, and the other side of the locking groove 8 forms a clearance space for the rotation of the lock tongue 9.

[0023] When the circuit breaker 2 is not in use in this embodiment, as shown in the attached Figure 1 and Figure 2 , close and lock the window cover 3 so that the circuit breaker 2 and the tongue lock 4 are respectively located in their independent compartments to obtain a better waterproof and dustproof effect. When the circuit breaker 2 needs to be used, as shown in the attached Figure 3 , open the tongue lock 4, and then flip up the window cover 3 to use the circuit breaker 2. The locking structure of this embodiment is: close the window cover 3, rotate the tongue lock 4 counterclockwise, and its lock tongue 9 rotates counterclockwise accordingly. When it rotates to the locked position, the lock tongue 9 inserts into the locking groove 8 to be in the locked state. Rotate the tongue lock 4 clockwise, and its lock tongue 9 rotates clockwise accordingly. The lock tongue 9 rotates out of the locking groove 8, and the lock tongue 9 is disengaged from the locking groove 8 to be unlocked.

[0024] The circuit breaker compartment of this embodiment is arranged in the following way: A first sealing groove is provided around the outside of the window cover 3, and a first sealing ring 10 is provided in the first sealing groove. The inner end face of the window cover 3 is in contact connection with the first sealing ring 10 to form a sealed circuit breaker compartment. Further, an annular end face with the same contour as the circuit breaker compartment is provided on the inner side of the window cover 3. The above arrangement of the circuit breaker compartment can make the circuit breaker compartment have better sealing performance and better dustproof and waterproof effects.

[0025] Further, a hand-tightening bolt 12 is provided at the bottom of the window cover 3. The hand-tightening bolt 12 is screwed and fixed with the base 1 to press the window cover 3. Preferably, a pair of hand-tightening bolts 12 are provided, which are respectively located on the left and right sides of the bottom of the window cover 3. The hand-tightening bolt 12 is used to further fix the window cover 3. In addition, by pressing the window cover 3, the end face of the window cover 3 can be closely combined with the first sealing ring 10 to form a better waterproof and dustproof structure.

[0026] To ensure that the window cover 3 is properly assembled with the base 1, and further ensure the stable formation of the partition chamber of the circuit breaker 2, a rabbet structure for mating and limiting is provided between the inner end face of the window cover 3 and the first sealing groove.

[0027] To further enhance the waterproof performance of the panel, a second sealing groove is provided on the rear side of the base 1, and a second sealing ring 11 for sealing connection with the installation plane is arranged in the second sealing groove.

[0028] To further enhance the waterproof performance of the panel, a waterproof rubber plug 13 is arranged at the installation hole of the base 1.

[0029] The installation structure of the circuit breaker 2 in this embodiment is as follows: mounting brackets 14 fixedly connected to the base 1 are arranged on both sides of the circuit breaker 2, and a mounting backplate 15 fixedly connected to the mounting brackets 14 is arranged at the rear side of the circuit breaker 2. During installation, first fix the mounting brackets 14 on the bottom plate through fasteners, then insert the circuit breaker 2 into the window, and finally complete the installation by fastening and connecting the mounting backplate 15 and the mounting brackets 14 through fasteners.

[0030] An opening cover plate 16 bent outward is arranged at the bottom of the window cover 3, and an opening gap is formed between the bottom of the opening cover plate 16 and the base 1; preferably, the opening cover plate 16 is centrally arranged at the bottom of the window cover 3; after unlocking, the window cover 3 can be conveniently opened through the opening cover plate 16.

[0031] The above embodiments are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
