[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a high and low voltage complete set of equipment with a protective cover, including a cabinet 1. The cabinet 1 serves as the supporting frame for the entire equipment, providing installation space and protection for internal electrical components. A cabinet door 4 is provided on the front surface of the cabinet 1, facilitating operation, inspection, and maintenance of the equipment. A display and control buttons are provided on the front surface of the cabinet door 4. A protective component 2 is also provided on the front surface of the cabinet door 4, primarily protecting the display and control buttons on the cabinet door 4 from external factors such as misoperation, dust, and moisture. The protective component 2 includes a protective cover. 21. Mounting block 23 and mounting slot 22. The protective cover 21 is made of transparent polycarbonate material, which has the advantages of high strength, high transparency, impact resistance and good weather resistance. The data on the display and the status of the control buttons can be clearly observed through the protective cover 21, while the buttons can be effectively protected. The protective cover 21 is rectangular and can completely cover the display and control buttons. The mounting block 23 is matched with the size of the mounting slot 22 to install the protective cover 21. The mounting slot 22 is opened on the upper part of the front surface of the cabinet door 4. The left and right sides of the mounting slot 22 are provided with round grooves 24 for inserting round rods 25 to quickly install the protective cover 21.
[0019] Furthermore, the mounting block 23 is hinged to the top of the protective cover 21, and the mounting block 23 is inserted into the inner wall of the mounting groove 22. Both sides of the mounting block 23 are slidably connected to round rods 25 that are inserted into the round grooves 24 to quickly install the protective cover 21. Both sets of round rods 25 are elastically connected to the mounting block 23 via return springs 27. The front surfaces of both sets of round rods 25 are fixedly connected to levers 26 that drive the two sets of round rods 25 to move and quickly remove them. Both sets of levers 26 are slidably connected to the top of the mounting block 23. The two sets of round rods 25 are respectively engaged with the inner walls of the two sets of round grooves 24. The top and rear of the levers 26 are... The device is designed in a block shape, with a circular sleeve at the front. The lever 26 is L-shaped, allowing for stable movement and limiting. The outer ends of the rear surfaces of the two sets of round rods 25 are beveled. This bevel allows the mounting block 23 to be directly pushed into the mounting slot 22 during installation. Simultaneously, the cabinet door 4 presses against the beveled surfaces of the round rods 25, causing the two sets of round rods 25 to move inward and compress the return spring 27. After the mounting block 23 is fully inserted into the mounting slot 22, the elastic force of the return spring 27 allows the two sets of round rods 25 to return to their original positions and be inserted into the two sets of round slots 24, thus quickly installing the protective cover 21. The operation is convenient.
[0020] Reference Figure 2 , Figure 3 and Figure 4 A limiting component 3 is provided on the upper part of the front surface of the cabinet door 4. The limiting component 3 includes a locking block 31 that limits the protective cover 21. A slider 34 that allows the locking block 31 to move stably is fixedly connected to the left side of the rear surface of the locking block 31. A sliding groove 35 is provided on the right side of the top of the front surface of the cabinet door 4 near the mounting groove 22. Two sets of slots 33 are also provided on the right side of the top of the front surface of the cabinet door 4 near the sliding groove 35. The two sets of slots 33 cooperate with the threaded rod 32 to limit the locking block 31. The slider 34 is slidably connected to the inner wall of the sliding groove 35. A threaded rod 32 that limits the locking block 31 is threaded through and threaded to the front surface of the locking block 31. The rear end of the threaded rod 32 is set as a smooth cylindrical shape. The rear end of the threaded rod 32 is inserted into the inner wall of the two sets of slots 33 respectively. The contact is located on the top right side of the protective cover 21 or on the rear surface of the protective cover 21. Both the slider 34 and the groove 35 are dovetail-shaped. The front end of the threaded rod 32 is set as an anti-slip cylindrical shape. The protective cover 21 can be limited by moving the locking block 31 to the top right side of the protective cover 21. At the same time, the threaded rod 32 is rotated and inserted into the slot 33 on the left side, thus limiting the locking block 31 and the protective cover 21 simultaneously. When it is necessary to open the protective cover 21, first move the locking block 31 to the right, then open the protective cover 21, and then move the locking block 31 to the left so that the locking block 31 supports the rear surface of the protective cover 21, so that the protective cover 21 is in the open state and opened 90° to a horizontal state, thus supporting the open protective cover 21.
[0021] Working principle: In use, by holding the protective cover 21, align the mounting block 23 with the mounting groove 22 opened on the upper part of the front surface of the cabinet door 4, and directly push the mounting block 23 into the mounting groove 22. During the process of the mounting block 23 being inserted into the mounting groove 22, the cabinet door 4 will squeeze the inclined surface of the outer end of the rear surface of the round rod 25. Due to the existence of the inclined surface, the round rod 25 is subjected to inward pressure, which overcomes the elastic force of the return spring 27 and slides and retracts into the mounting block 23. When the mounting block 23 is fully inserted into the mounting groove 22, the round rod 25 is no longer squeezed by the cabinet door 4. At this time, the return spring 27 returns to its original state and generates elastic force to push the round rod 25 outward, so that the two sets of round rods 25 are respectively inserted into the round grooves 24 opened on the left and right sides of the mounting groove 22, thereby realizing the quick installation of the protective cover 21. The control buttons and display on the front surface of the cabinet door 4 can be protected by the installation of the protective cover 21.
[0022] When it is necessary to remove the protective cover 21, by moving the lever 26, the lever 26 slides on the top of the mounting block 23, which drives the round rod 25 fixedly connected to it to move into the mounting block 23. The round rod 25 overcomes the elastic force of the return spring 27 and gradually disengages from the round groove 24. When the round rod 25 is completely disengaged from the round groove 24, the operator can pull the mounting block 23 out of the mounting groove 22, thereby completing the removal of the protective cover 21. The operation is convenient.
[0023] When it is necessary to limit the protective cover 21, move the locking block 31 to the left, move the locking block 31 to the top right side of the protective cover 21, and then rotate the threaded rod 32. During the rotation, the smooth cylindrical part of the rear end of the threaded rod 32 will gradually insert into the slot 33 on the left. When the threaded rod 32 is fully inserted into the slot 33, the position of the locking block 31 is fixed, and at the same time, the locking block 31 contacts the right side of the top of the protective cover 21, thereby limiting the protective cover 21 and preventing the protective cover 21 from shaking or opening at will.
[0024] When it is necessary to open the protective cover 21, first unscrew the threaded rod 32 from the slot 33, then move the locking block 31 to the right so that the locking block 31 is away from the right side of the top of the protective cover 21, and the protective cover 21 can be opened. Since the top of the protective cover 21 is hinged to the mounting block 23, the protective cover 21 can be rotated to open around the hinge point. After the protective cover 21 is opened to 90° and is in a horizontal state, move the locking block 31 to the left so that the locking block 31 is supported on the rear surface of the protective cover 21. At this time, the locking block 31 plays a supporting role, supporting the open protective cover 21 and keeping it in a horizontal open state, which makes it convenient for operators to operate or maintain the equipment.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
