[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the branch control switch. Each branch is set according to its needs.

[0003] Since the cabinet contains circuit breakers, transformers, contactors, relays, capacitors, resistors, etc., heat will be generated when working. At the same time, the components are densely packed, the cabinet space is limited, the heat dissipation is not smooth, and the heat island is accumulated, causing the temperature to rise. Therefore, the existing technology usually achieves heat dissipation in the cabinet by means of grooving, opening windows, etc.

[0004] However, although directly grooving the cabinet can achieve heat dissipation, unauthorized personnel may come into contact with internal components through the heat dissipation openings, thereby posing a safety hazard.

[0005] Therefore, how to achieve heat dissipation of the switch cabinet while improving the safety of the switch cabinet has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a safety switch cabinet which can allow the heat generated by the electronic components in the first installation position to enter the atmosphere through the gap between the ventilation plate and the cabinet body by rotating the ventilation plate.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it is composed of a cabinet body, the length direction of the cabinet body extends up and down and includes a first mounting position and a second mounting position, and also includes bolts.

The cabinet body is provided with a positioning plate for installation on the rear rotating shaft, and the cabinet body is provided with a control door detachably installed on the rear side of the positioning plate, a fixing hole is provided on the rear rotating shaft, and a first positioning hole and a second positioning hole are provided on the positioning plate, and the angle between the first positioning hole and the second positioning hole is 45°. The bolt is inserted into the first positioning hole or the second positioning hole and cooperates with the fixing hole thread.

[0008] The utility model is further configured as follows: the cabinet comprises a placement groove for placing the ventilation plate, a first magnet is fixedly installed at the bottom of the ventilation plate, and a second magnet is arranged in the placement groove of the cabinet.

[0009] The utility model is further configured as follows: a plurality of heat dissipation ribs are protrudingly arranged on the control door, and the heat dissipation ribs are arranged on the control door at intervals along the left-right direction.

[0010] The utility model is further configured as follows: the control door is provided with a plurality of heat dissipation holes between adjacent heat dissipation ribs, and the heat dissipation holes are arranged at intervals along the up-down direction on the control door.

[0011] The utility model is further configured as follows: it also includes a fan, on which a motor is fixedly mounted and the wiring method is the existing technology, which is not elaborated in detail here; the cabinet is provided with ventilation slots on the left and right sides of the second mounting position, and the fan is detachably mounted in the ventilation slots.

[0012] The utility model is further configured as follows: a heat dissipation groove is provided at the bottom of the cabinet at the second installation position, a heat dissipation plate is rotatably installed in the heat dissipation groove, a mounting plug is provided on the heat dissipation plate, a plurality of through holes are provided on the heat dissipation plate, a mounting slot is provided on the rotation track of the mounting plug, and the mounting block is located in the mounting slot and is detachably connected to the cabinet.

[0013] The utility model is further configured as follows: the cabinet body is provided with a limit block made of a deformable material protruding from the installation slot, the limit block is L-shaped and includes a limit plate, and the limit plate is located at the front side of the installation block.

[0014] By adopting the above technical solution, 1. Since the first positioning hole and the second positioning hole are provided on the positioning plate, the bolt can be inserted into the first positioning hole or the second positioning hole by rotating the positioning plate, and then fixed with the fixing hole to change the rotation angle of the positioning plate. When the bolt on the rear rotating shaft of the positioning plate is inserted into the first positioning hole or the second positioning hole, the ventilation plate can be rotated and opened relative to the cabinet, or rotated and closed, and the user can choose whether to open the ventilation plate according to needs; 2. Since the angle between the first positioning hole and the second positioning hole is 45°, that is, the ventilation plate can only be rotated 45° relative to the cabinet, so in this state, it is difficult for unrelated personnel to reach into the first installation position through the gap between the ventilation plate and the cabinet and contact the electronic components, thereby improving safety; 3.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 7As shown, the utility model discloses a safety switch cabinet, which is composed of a cabinet body 1. The length direction of the cabinet body 1 extends up and down and includes a first mounting position 11 and a second mounting position 12. Since the cabinet body 1 includes the first mounting position 11 and the second mounting position 12, the installation of each electronic component can be achieved by placing each electronic component in the first mounting position 11 and the second mounting position 12. The cabinet body 1 also includes bolts (not shown in the figure). The cabinet body 1 is rotatably installed with a ventilation plate 13 on the left and right sides of the first mounting position 11. The ventilation plate 13 includes a rear shaft 131. The cabinet body 1 is provided with a positioning plate 14 for loading on the rear shaft 131, and the cabinet is provided with a control door 15 detachably installed on the rear side of the positioning plate 14 by bolts, magnetic attraction, etc., and a fixing hole 1311 is provided on the rear shaft 131, and a first positioning hole 141 and a second positioning hole 142 are provided on the positioning plate 14, and the angle between the first positioning hole 141 and the second positioning hole 142 is 45°, and the bolt is inserted into the first positioning hole 141 or the second positioning hole 142 and is threadedly matched with the fixing hole 1311, 1. Since the positioning plate 14 is provided with a first positioning hole 141 or a second positioning hole 142, the fixing hole 15 can be installed on the cabinet body. The first positioning hole 141 and the second positioning hole 142 are provided, so that by rotating the positioning plate 14, the bolt can be inserted into the first positioning hole 141 or the second positioning hole 142 and then fixed with the fixing hole 1311 to change the rotation angle of the positioning plate 14. When the bolt on the rear rotating shaft 131 of the positioning plate 14 is inserted into the first positioning hole 141 or the second positioning hole 142, the ventilation plate 13 can be rotated to be opened or closed relative to the cabinet body 1, and the user can choose whether to open the ventilation plate 13 according to the needs; 2. Since the first positioning hole 141 and the second positioning hole 142 are provided, the rotation angle of the positioning plate 14 can be changed. When the bolt on the rear rotating shaft 131 of the positioning plate 14 is inserted into the first positioning hole 141 or the second positioning hole 142, the ventilation plate 13 can be rotated to be opened or closed relative to the cabinet body 1, and the user can choose whether to open the ventilation plate 13 according to the needs. The angle between the positioning holes 142 is 45°, that is, the ventilation plate 13 can only rotate 45° compared with the cabinet 1. Therefore, in this state, it is difficult for unauthorized personnel to extend their hands through the gap between the ventilation plate 13 and the cabinet 1 into the first installation position 11 and contact the electronic components, thereby improving safety; 3. Since the positioning plate 14 is located on the rear side of the rear shaft 131, during the use of the cabinet 1, it is difficult for unauthorized personnel to contact the positioning plate 14 and will not disassemble the control door 15, so that the state of the ventilation plate 13 will not be easily changed without the action of external force; 4. By rotating the ventilation plate 13, ventilation adjustment can be achieved without occupying additional space, the internal layout of the cabinet 1 is optimized, and space utilization is maximized.

[0028] Preferably, the cabinet body 1 includes a placement groove 16 for the ventilation plate 13 to be placed, and a first magnet 132 is fixedly installed on the bottom of the ventilation plate 13 by bonding or the like. The cabinet body 1 is provided with a second magnet 161 in the placement groove 16. When the control door 15 is removed and then the bolts are removed and then the rear rotating shaft of the rotating ventilation plate 13 is rotated so that it is completely placed in the placement groove 16, the first magnet 132 can attract the second magnet 161, so that the rear rotating shaft 131 of the ventilation plate 13 that has not yet been bolted and is completely located in the placement groove 16 will be directly aligned with the first positioning hole 141 or the second positioning hole 142 at this time, thereby providing convenience for reinserting the bolts.

[0029] Among them, a number of heat dissipation ribs 133 are protrudingly provided on the control door 15, and the heat dissipation ribs 133 are arranged at intervals in the left-right direction on the control door 15. The setting of the heat dissipation ribs 133 provides a new way for the heat dissipation of the control door 15, and this way can achieve heat dissipation regardless of whether the control door 15 is rotated. Specifically, the surface area of ​​the control door 15 is increased, and the contact between the air and the surface of the control door 15 is improved, thereby enhancing the heat exchange efficiency, effectively dissipating the heat of the components behind the control door 15, and reducing the temperature in the cabinet. At the same time, structural reinforcement is provided to make the control door 15 more sturdy, and even under high temperature or long-term stress conditions, it can maintain a stable shape, reduce the risk of deformation, and improve the overall structural strength.

[0030] Preferably, the control door 15 is provided with a plurality of heat dissipation holes 134 between adjacent heat dissipation ribs 133, and the heat dissipation holes 134 are arranged at intervals in the up-down direction on the control door 15. 1. Heat dissipation holes 134 are added between adjacent heat dissipation ribs 133 to form an air circulation channel. These holes are arranged at intervals in the up-down direction, which directly increases the air permeability of the control door 15 and makes the airflow more unobstructed; 2. When the control door 15 is flipped open, the heat dissipation holes 134 are combined with the heat dissipation ribs 133 to promote heat convection inside and outside the control door 15. The hot air rises and is discharged through the heat dissipation holes 134, and the cold air is sucked in from below, forming effective convection and improving the heat dissipation efficiency.

[0031] In addition, it also includes a fan 2, on which a motor 21 is fixedly installed and the wiring method is the existing technology, which will not be elaborated in detail here. The cabinet 1 is provided with ventilation grooves 135 on the left and right sides of the second installation position, and the fan 2 is detachably installed in the ventilation grooves 135 by bolts. Since the fan 2 is located in the ventilation grooves 135, starting the fan 2 can realize convection between the second installation position 12 and the outside air and thus realize heat dissipation in the second installation position 12. Moreover, since the fan 2 is detachably installed in the ventilation grooves 135, when the fan 2 needs to be cleaned or repaired, the fan 2 can be directly removed from the cabinet 1 and then repaired and cleaned.

[0032] The cabinet 1 is provided with a heat dissipation slot 17 at the bottom of the second installation position 12, and a heat dissipation plate 18 is rotatably installed in the heat dissipation slot 17 of the cabinet 1. A mounting plug 181 is provided on the heat dissipation plate 18, and a plurality of through holes 182 are provided on the heat dissipation plate 18. The cabinet is provided with a mounting slot 19 on the rotation track of the mounting plug 181. The mounting plug 181 is located in the mounting slot 19 and can be detachably connected to the cabinet by bolts, magnetic attraction, etc. 1. The heat dissipation slot 17 is provided at the bottom of the cabinet 1, which directly increases the bottom air circulation path, is conducive to removing the hot air accumulated in the cabinet, especially for the heating components under gravity, and improves the overall heat dissipation efficiency; 2. The through holes 182 on the heat sink 18 are designed to increase the air circulation area and cooperate with the heat sink 17 to form an effective air channel, which accelerates the circulation of hot air, improves heat exchange, and reduces the internal temperature; 3. The rotating heat sink 18 enables the heat sink 17 to be connected to the outside world at an angle and when it is necessary to clean the dust in the through holes 182 on the heat sink 18, it provides a way to release the connection between the installation plug 181 and the cabinet 1 so that the back side of each through hole 182 can be contacted to facilitate the cleaning of the heat sink 18.

[0033] Preferably, the cabinet is provided with a limit block 3 made of rubber or other easily deformable material protruding from the installation slot 19, the limit block 3 is L-shaped and includes a limit plate 31, the limit plate 31 is located in front of the installation block 181, since the limit plate 31 is L-shaped and the front limit plate 31 will be located in front of the installation block 181, that is, it will be against the installation block 181, so the installation block 181 can be stably located in the installation slot 19 in the absence of external force, and when the heat sink 18 needs to be rotated, the limit plate 31 can be deformed by applying a force to the limit block 3, thereby separating the installation block 181 from the installation slot 19 and realizing the rotation of the heat sink 18.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
