[0002] Low-voltage cabinets are widely used in various fields of power systems, and play a very important role in industry, commerce and residence. Specifically, they can be widely used in some large industrial equipment to ensure the normal operation and safety of factories and workshops; they can also be used in commercial buildings such as shopping malls, hotels, supermarkets, and public facilities such as schools, hospitals, and subways.

[0003] A low-voltage cabinet refers to electrical equipment with a rated working voltage not exceeding 1000V. It is usually used in power distribution systems in factories, buildings, residential areas and other places. The main function of the low-voltage cabinet is to convert and distribute the input electrical energy to provide the required power for various electrical equipment. When a general low-voltage cabinet is in use, the connecting wire needs to be plugged and unplugged from the plug inside the low-voltage cabinet. When the number of plugging and unplugging times is large, the connection wire and the plug will become loose, which will cause the connection wire to fall off. Therefore, it needs to be modified and optimized. Summary of the invention

[0004] The object of the present invention is to provide a low-voltage cabinet for electric power equipment to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention provides the following technical solution: a low-voltage cabinet for electric power equipment, comprising a cabinet body and a cabinet door, wherein the cabinet door is hinged to one side of the cabinet body;

[0006] A connector is fixedly installed on one side of the cabinet body, and a top plate and a bottom plate are fixedly installed on one side of the connector, the bottom plate is located at the bottom of the top plate, a groove is opened on the top of the bottom plate, a handle is rotatably installed on the top of the top plate, the bottom of the handle passes through the upper and lower sides of the top plate and is fixedly installed with a threaded rod 1, the bottom of the threaded rod 1 is rotatably connected to the bottom plate, a threaded rack is threadedly sleeved on the outer surface of the threaded rod 1, a limiting plate is fixedly installed on the bottom of the threaded rack, a sliding rod is fixedly installed between the top plate and the bottom plate, and the sliding rod is movably sleeved with the threaded rack.

[0007] Preferably, a fixing plate is fixedly installed on the side surface inside the cabinet, a spring is fixedly installed on one side of the fixing plate, a contact plate is fixedly installed on one end of the spring, a limiting rod is fixedly installed on one side of the contact plate, one end of the limiting rod passes through the left and right sides of the fixing plate, and a rubber plate is fixedly installed on one side of the cabinet door, and the rubber plate is movably connected to the contact plate.

[0008] Preferably, a threaded rod 2 is fixedly installed at the bottom of the cabinet, a threaded sleeve is threadedly sleeved on the outer surface of the threaded rod 2, a bottom plate is fixedly installed at the bottom of the threaded sleeve, and a rotating plate is fixedly installed on the outer side of the threaded sleeve.

[0009] Preferably, a fan is fixedly installed above the cabinet, and the bottom of the fan extends to the inside of the cabinet.

[0010] Preferably, a protective net is fixedly installed above the cabinet, and the protective net is located on the outer surface of the fan.

[0011] Preferably, wire holes are respectively opened on the left and right sides of the cabinet, and the wire holes are circular in shape.

[0012] Preferably, heat dissipation holes are provided on both the left and right sides of the cabinet, and two heat dissipation holes are provided on both the left and right sides of the cabinet.

[0013] Preferably, a handle is fixedly mounted on one side of the cabinet door, and the handle is located on the outside of the cabinet body.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention inserts the connecting wire into the connector and rotates the handle to drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the threaded frame, the threaded frame and the limit plate move downward as the threaded rod rotates until the limit plate and the bottom plate are in contact with the connecting wire. Then, the handle stops rotating. Compared with the traditional device, the device fixes the connecting wire so that the connection between the connecting wire and the connector is more fixed and stable, thereby improving the working efficiency of the device.

[0016] 2. The present invention drives the rubber plate to move by closing the cabinet door. When the cabinet door contacts the cabinet body, the rubber plate pushes the contact plate to move backward, which in turn moves the limit rod backward and compresses the spring. At the same time, the spring reaction force makes the contact plate and the rubber plate in close contact. Compared with the traditional device, the device is more tightly connected between the cabinet door and the cabinet body, avoiding the poor sealing effect between the cabinet body and the cabinet door, so that the accumulated water at the bottom of the outer side of the device enters the interior of the device through the gap between the cabinet body and the cabinet door, thereby improving the sealing performance of the device.

[0017] 3. The present invention rotates the rotating plate with the threaded sleeve, and the rotation of the threaded sleeve drives the bottom plate to rotate, and the threaded sleeve and the threaded rod are threadedly connected, so that the threaded sleeve moves downward, and then the bottom plate moves downward and is in close contact with the ground. When the four bottom plates are in contact with the ground and the device is horizontal, the rotation of the rotating plate can be stopped. Compared with the traditional device, the device adjusts its own balance to avoid the device from tilting due to the uneven bottom ground when placed, thereby improving the stability of the device after placement.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, an embodiment of the present invention provides a low-voltage cabinet for electric power equipment, comprising a cabinet body 1, a cabinet door 4, and the cabinet door 4 is hinged to one side of the cabinet body 1;

[0029] A connector 12 is fixedly installed on one side inside the cabinet 1, and a top plate 13 and a bottom plate 14 are fixedly installed on one side of the connector 12. The bottom plate 14 is located at the bottom of the top plate 13, and a groove 16 is opened on the top of the bottom plate 14. A handle 15 is rotatably installed on the top of the top plate 13. The bottom of the handle 15 passes through the upper and lower sides of the top plate 13 and is fixedly installed with a threaded rod 17. The bottom of the threaded rod 17 is rotatably connected to the bottom plate 14, and a threaded frame 18 is threadedly sleeved on the outer surface of the threaded rod 17. A limiting plate 19 is fixedly installed on the bottom of the threaded frame 18. A sliding rod 25 is fixedly installed between the top plate 13 and the bottom plate 14, and the sliding rod 25 is movably sleeved with the threaded frame 18.

[0030] When the staff uses it, the staff first inserts one end of the connecting line into the interior of the connector 12, and then turns the handle 15. When the handle 15 is turned, the threaded rod 17 is driven to rotate. When the threaded rod 17 is turned, since the connection between the threaded frame 18 and the threaded rod 17 is provided with threads, the threaded frame 18 is driven to move downward as the threaded frame 18 moves downward. When the threaded frame 18 moves downward, the limit plate 19 is driven to move downward. When the bottom of the limit plate 19 and the top of the bottom plate 14 are in contact with the connecting line, the handle 15 can be stopped at this time.

[0031] By inserting the connecting wire into the connector 12, turning the handle 15 drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the threaded frame 18, as the threaded rod 17 rotates, the threaded frame 18 and the limit plate 19 move downward until the limit plate 19 and the bottom plate 14 are in contact with the connecting wire. Then, the handle 15 stops rotating. Compared with the traditional device, the device fixes the connecting wire so that the connection between the connecting wire and the connector 12 is more fixed and stable, thereby improving the working efficiency of the device.

[0032] Among them, a fixing plate 7 is fixedly installed on the side inside the cabinet body 1, a spring 8 is fixedly installed on one side of the fixing plate 7, a contact plate 10 is fixedly installed on one end of the spring 8, a limiting rod 9 is fixedly installed on one side of the contact plate 10, one end of the limiting rod 9 passes through the left and right sides of the fixing plate 7, and a rubber plate 11 is fixedly installed on one side of the cabinet door 4, and the rubber plate 11 is movably connected to the contact plate 10.

[0033] When the staff uses it, the staff first closes the cabinet door 4. When the cabinet door 4 is closed, it will rotate. As the cabinet door 4 rotates, the rubber plate 11 will be driven to move. When the cabinet door 4 contacts the cabinet body 1, the rubber plate 11 will contact the contact plate 10, thereby pushing the contact plate 10 to move backward. When the contact plate 10 moves backward, the limit rod 9 will move backward. When the limit rod 9 moves backward, the spring 8 will be compressed. At the same time, the spring 8 will also exert a certain force on the contact plate 10, so that the contact plate 10 and the rubber plate 11 are in close contact.

[0034] By closing the cabinet door 4, the rubber plate 11 is driven to move. When the cabinet door 4 contacts the cabinet body 1, the rubber plate 11 pushes the contact plate 10 to move backward, and the limit rod 9 is linked to move backward and compress the spring 8. At the same time, the reaction force of the spring 8 makes the contact plate 10 and the rubber plate 11 in close contact. Compared with the traditional device, the device is more tightly connected between the cabinet door 4 and the cabinet body 1. The poor sealing effect between the cabinet body 1 and the cabinet door 4 is avoided, so that the accumulated water at the bottom of the outer side of the device enters the interior of the device through the gap between the cabinet body 1 and the cabinet door 4, thereby improving the sealing performance of the device.

[0035] A threaded rod 20 is fixedly installed at the bottom of the cabinet 1 , a threaded sleeve 21 is threadedly sleeved on the outer surface of the threaded rod 20 , a bottom plate 22 is fixedly installed at the bottom of the threaded sleeve 21 , and a rotating plate 23 is fixedly installed on the outer side of the threaded sleeve 21 .

[0036] When the staff is in use, they first rotate the rotating plate 23. When the rotating plate 23 rotates, it will drive the threaded sleeve 21 to rotate. When the threaded sleeve 21 rotates, it will drive the bottom plate 22 to rotate. Since the connection between the threaded sleeve 21 and the threaded rod 20 is provided with threads, the threaded sleeve 21 will be driven to move downward as the threaded sleeve 21 rotates. When the threaded sleeve 21 moves downward, it will drive the bottom plate 22 to move downward, so that the bottom plate 22 is in close contact with the ground.

[0037] The threaded sleeve 21 is rotated by rotating the rotating plate 23, and the rotation of the threaded sleeve 21 drives the bottom plate 22 to rotate. The threaded sleeve 21 and the threaded rod 20 are threadedly connected, so that the threaded sleeve 21 moves downward, and then the bottom plate 22 moves downward and is in close contact with the ground. When the four bottom plates 22 are in contact with the ground and the device is horizontal, the rotation of the rotating plate 23 can be stopped. Compared with the traditional device, the device adjusts its own balance to avoid the device from tilting when placed due to the uneven ground at the bottom of the device, thereby improving the stability of the device after placement.

[0038] A fan 6 is fixedly installed on the top of the cabinet 1 , and the bottom of the fan 6 extends to the inside of the cabinet 1 .

[0039] By starting the fan 6, the hot air inside the cabinet 1 is blown out of the cabinet 1, and the interior of the cabinet 1 is quickly cooled to prevent the temperature inside the cabinet 1 from being too high.

[0040] A protective net 5 is fixedly installed above the cabinet 1 , and the protective net 5 is located on the outer surface of the fan 6 .

[0041] The protection net 5 is designed to block dust above the device, thereby preventing dust from entering the interior of the cabinet 1 and causing damage to the electronic components inside the cabinet 1 .

[0042] Wherein, wire holes 2 are respectively opened on the left and right sides of the cabinet body 1, and the shape of the wire holes 2 is circular.

[0043] Through the precise design of the wire hole 2, one end of the connecting wire can be easily inserted into the cabinet 1 through the wire hole 2. This design not only simplifies the connection process of the connecting wire and improves work efficiency, but also ensures the stability and safety of the connecting wire, avoids the potential safety hazards caused by the disordered connecting wires, provides a reliable connection guarantee for the normal operation of the equipment inside the cabinet 1, and also improves the overall aesthetics and neatness.

[0044] The cabinet body 1 is provided with heat dissipation holes 3 on both sides thereof, and the cabinet body 1 is provided with two heat dissipation holes 3 on both sides thereof.

[0045] The clever design of the heat dissipation holes 3, in coordination with the high-efficiency fan 6, achieves smooth exchange of air between the inside and outside of the cabinet 1. This combination not only significantly improves the heat dissipation efficiency inside the device, ensuring the stable performance of the equipment under long-term high-load operation, but also effectively prevents equipment failures caused by overheating, thereby extending the service life of the cabinet 1 and its internal components, and providing a strong guarantee for the safe and stable operation of the power system.

[0046] A handle 24 is fixedly mounted on one side of the cabinet door 4 , and the handle 24 is located on the outer side of the cabinet body 1 .

[0047] The cabinet door 4 can be opened by holding the handle 24. The design of the handle 24 makes it easy to open the cabinet door 4, thereby improving the working efficiency of the device.

[0048] Working principle and usage process:

[0049] When the staff uses it, the staff first inserts one end of the connecting line into the interior of the connector 12, and then turns the handle 15. When the handle 15 is turned, the threaded rod 17 is driven to rotate. When the threaded rod 17 is turned, since the connection between the threaded frame 18 and the threaded rod 17 is provided with threads, the threaded frame 18 is driven to move downward as the threaded frame 18 moves downward. When the threaded frame 18 moves downward, the limit plate 19 is driven to move downward. When the bottom of the limit plate 19 and the top of the bottom plate 14 are in contact with the connecting line, the handle 15 can be stopped at this time.

[0050] When the staff uses it, the staff first closes the cabinet door 4. When the cabinet door 4 is closed, it will rotate. As the cabinet door 4 rotates, the rubber plate 11 will be driven to move. When the cabinet door 4 contacts the cabinet body 1, the rubber plate 11 will contact the contact plate 10, thereby pushing the contact plate 10 to move backward. When the contact plate 10 moves backward, the limit rod 9 will move backward. When the limit rod 9 moves backward, the spring 8 will be compressed. At the same time, the spring 8 will also exert a certain force on the contact plate 10, so that the contact plate 10 and the rubber plate 11 are in close contact.

[0051] When the staff is in use, they first rotate the rotating plate 23. When the rotating plate 23 rotates, it will drive the threaded sleeve 21 to rotate. When the threaded sleeve 21 rotates, it will drive the bottom plate 22 to rotate. Since the connection between the threaded sleeve 21 and the threaded rod 20 is provided with threads, the threaded sleeve 21 will be driven to move downward as the threaded sleeve 21 rotates. When the threaded sleeve 21 moves downward, it will drive the bottom plate 22 to move downward, so that the bottom plate 22 is in close contact with the ground.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
