[0002] High and low voltage switchgear are power distribution equipment used in power supply systems for power distribution, control, metering, and cable connection. They are commonly referred to as high and low voltage switchgear or high and low voltage electrical complete sets of equipment. High and low voltage switchgear are indispensable equipment in power systems. They are mainly used to introduce electrical energy from the high-voltage side, step it down through transformers, and then distribute it to various electrical devices through low-voltage switchgear. They integrate protective devices such as switches, circuit breakers, and fuses, as well as control elements such as buttons, indicator lights, and meters, forming a complete power distribution device.

[0003] Chinese Utility Model Patent Publication No. CN222146899U discloses a power distribution cabinet that is easy to maintain. This cabinet uses a fixed block for maintenance. When maintenance is needed, opening the cabinet door lock and pulling the door causes a rotating shaft fixed to the side wall of the door to rotate within the fixed block, thus opening the door. During maintenance, the front door is opened first. If it is necessary to inspect cables near the sides of the cabinet, the side doors can be opened, providing ample maintenance space for personnel. Simultaneously, a lighting mechanism above the door illuminates the interior of the cabinet, facilitating maintenance. However, this easy-to-maintain power distribution cabinet lacks an adjustment mechanism, making it inconvenient to adjust the distance between adjacent mounting plates and to install electrical components of different sizes, resulting in low adaptability. Furthermore, it lacks a sealing structure, allowing humid air to easily enter the cabinet through the connection between the door and the main body in humid environments, potentially damaging electrical components. Its poor sealing performance and practicality limit its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high and low voltage distribution cabinet that is easy to maintain. It can effectively solve the problems of existing technology, such as inconvenience in adjusting the distance between adjacent mounting plates, inconvenience in installing electrical components of different sizes, low adaptability, lack of a sealing structure, easy entry of humid air into the cabinet body through the connection between the cabinet door and the cabinet body in humid environments, resulting in damage to electrical components, low sealing performance, poor practicality, and inconvenience for widespread use.

[0005] The technical solution adopted by this utility model is as follows: a high and low voltage distribution cabinet that is easy to maintain, including a cabinet body and a cabinet door. A fixing frame is fixedly installed inside the cabinet body. A fixing rod 1 and a fixing rod 2 are fixedly installed inside the fixing frame. A groove 1 is formed on the side of the fixing rod 1 away from the cabinet body. A sliding rod is fixedly installed inside the groove 1. A groove 2 is formed on the side of the fixing rod 2 away from the cabinet body. A limit groove 1 is formed at the top of the fixing rod 2. An installation frame is provided inside the fixing frame.

[0009] With the above technical solution, during installation, the operator moves the mounting bracket to the innermost part of the distribution cabinet body using the cooperation of the slider and the sliding rod. Then, the limiting rod passes through the limiting slot one and the limiting slot two, which can quickly limit the mounting bracket. When electrical components need to be repaired, the operator pulls out the limiting rod from the limiting slot one and the limiting slot two, and then moves the mounting bracket to the front of the distribution cabinet body using the cooperation of the slider and the sliding rod. Then, the limiting rod passes through the limiting slot one and the limiting slot two at the other end of the fixing rod two, which can quickly limit the mounting bracket. When repairing electrical components, the operator does not need to put their hands into the inside of the distribution cabinet body to operate. The operating space is large, which facilitates the operator's repair and improves the repair efficiency.

[0010] Preferably, the guide block and the guide groove are plugged in, and the cross-section of the guide block has a "T" shape.

[0011] Using the above technical solution, the staff inserts the guide block into the guide groove and then presses the guide block down so that it is completely submerged in the guide groove, which can achieve rapid positioning of the mounting plate and facilitate subsequent work.

[0012] Preferably, the bolt extends through threaded hole one into threaded hole two, and threaded hole one and threaded hole two have the same diameter.

[0013] With the above technical solution, after the mounting plate is quickly positioned, the workers can extend the bolt through the first threaded hole to the second threaded hole, which can realize the quick installation of the mounting plate and facilitate its maintenance after long-term use.

[0014] Preferably, the guide groove and the threaded hole are provided in multiple identical forms, and the multiple guide grooves and threaded holes are distributed at equal intervals. The number of guide grooves is twice the number of threaded holes.

[0015] The above technical solution, through the design of multiple guide grooves and threaded holes, facilitates the adjustment of the distance between adjacent mounting plates, making it easy to install electrical components of different sizes, and has high adaptability.

[0016] Preferably, the outer side of the power distribution cabinet body is provided with ventilation openings, and multiple identical ventilation openings are provided, with the multiple ventilation openings distributed at equal intervals.

[0017] The above technical solution, through the design of the ventilation openings, facilitates air circulation inside the distribution cabinet, avoids electrical components from working in a high-temperature environment for a long time, thus preventing damage and improving their service life. The overall heat dissipation performance is also high.

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.

[0032] Example 1:

[0033] like Figure 1-9 As shown, this utility model provides a high and low voltage distribution cabinet that is easy to maintain, including a cabinet body 1 and a cabinet door 2. A fixing frame 9 is fixedly installed inside the cabinet body 1. A fixing rod 10 and a fixing rod 2 11 are fixedly installed inside the fixing frame 9. A groove 12 is formed on the side of the fixing rod 10 away from the cabinet body 1. A sliding rod 13 is fixedly installed inside the groove 12. A groove 24 is formed on the side of the fixing rod 2 11 away from the cabinet body 1. A limit groove 15 is formed at the top of the fixing rod 2 11. A mounting bracket 16 is provided inside the fixing frame 9. The mounting bracket 16 is close to the fixing frame 9.

A guide block 22 is fixedly installed on the side of the mounting plate 21 near the mounting bracket 16. A guide groove 24 and a threaded hole 25 are opened on the outer side of the mounting plate 21. A bolt 26 is threadedly connected to the side of the mounting plate 21 away from the mounting bracket 16. An electrical component 27 is fixedly installed on the side of the mounting plate 21 away from the mounting bracket 16.

[0034] Specifically, the distribution cabinet body 1 has a mounting groove 3 and a mounting groove 4 on the side near the cabinet door 2. A soft magnet 5 is inserted into the mounting groove 3, and a sealing ring 6 is installed inside the mounting groove 4. The cabinet door 2 has a mounting groove 7 on the side near the distribution cabinet body 1, and a soft magnet 8 is inserted into the mounting groove 7. The soft magnets 5 and 8 are magnetically connected, and the sealing ring 6 is a rubber ring. The advantages are that when the operator rotates the cabinet door 2, it comes into contact with the distribution cabinet body 1, and the soft magnets 5 and 8 attract each other, making the connection between the cabinet door 2 and the distribution cabinet body 1 tighter. In humid environments, this prevents humid air from entering the distribution cabinet body 1 through the connection between the cabinet door 2 and the distribution cabinet body 1, thus preventing damage to electrical components 27 and affecting the normal operation of the entire unit. The sealing performance is high, and because the rubber ring has good sealing properties, the design of the sealing ring 6 further improves the overall sealing performance, making it highly practical.

[0035] Specifically, slider 17 and slider 13 are slidably connected, and limit rod 20 passes through limit groove 15 and limit groove 29. Limit groove 15 and limit groove 29 have the same diameter. The advantages are that the operator moves the mounting bracket 16 to the innermost part of the distribution cabinet body 1 through the cooperation of the slider 17 and the slide rod 13, and then passes the limiting rod 20 through the limiting groove 15 and the limiting groove 19 to achieve quick positioning of the mounting bracket 16. When it is necessary to repair the electrical component 27, the operator pulls the limiting rod 20 out of the limiting groove 15 and the limiting groove 19, and then moves the mounting bracket 16 to the front of the distribution cabinet body 1 through the cooperation of the slider 17 and the slide rod 13. Then, the operator passes the limiting rod 20 through the limiting groove 15 and the limiting groove 19 at the other end of the fixing rod 21 to achieve quick positioning of the mounting bracket 16. When repairing the electrical component 27, the operator does not need to put their hands into the inside of the distribution cabinet body 1 to operate, the operating space is large, which facilitates the operator's repair and improves the repair efficiency.

[0036] Specifically, the outer side of the distribution cabinet body 1 is provided with ventilation openings 28. Multiple identical ventilation openings 28 are provided and are evenly spaced. The advantage is that the design of the ventilation openings 28 facilitates air circulation inside the distribution cabinet body 1, preventing electrical components 27 from operating in a high-temperature environment for extended periods, thus extending their service life and improving overall heat dissipation performance.

[0037] Example 2:

[0038] like Figure 2-9As shown, as an improvement on the previous embodiment, to further facilitate the installation of the mounting plate 21, specifically, the guide block 22 and the guide groove 24 are plugged in, and the cross-section of the guide block 22 has a "T" shape. The advantage is that the operator inserts the guide block 22 into the guide groove 24 and then presses the guide block 22 downwards, so that the guide block 22 is completely submerged in the guide groove 24, which enables rapid positioning of the mounting plate 21 and facilitates subsequent work.

[0039] Specifically, bolt 26 extends through threaded hole 23 to the interior of threaded hole 25, with threaded hole 23 and threaded hole 25 having the same diameter. The advantage is that after quickly positioning the mounting plate 21, workers can quickly install the mounting plate 21 by extending bolt 26 through threaded hole 23 to threaded hole 25, and it is convenient for maintenance after prolonged use.

[0040] Specifically, multiple identical guide grooves 24 and threaded holes 25 are provided, and the guide grooves 24 and threaded holes 25 are evenly spaced. The number of guide grooves 24 is twice the number of threaded holes 25. The advantage is that the design of multiple guide grooves 24 and threaded holes 25 facilitates the adjustment of the distance between adjacent mounting plates 21, and facilitates the installation of electrical components 27 of different sizes, resulting in high adaptability.

[0041] Working principle: During installation, the operator inserts the guide block 22 into the guide groove 24, and then presses the guide block 22 downwards until it is completely submerged in the guide groove 24. This allows for quick positioning of the mounting plate 21, facilitating subsequent work. After quickly positioning the mounting plate 21, the operator inserts the bolt 26 through the threaded hole 23 to the threaded hole 25, enabling quick installation of the mounting plate 21. This design also facilitates maintenance after prolonged use. The multiple guide grooves 24 and threaded holes 25 facilitate phase adjustment. The distance between adjacent mounting plates 21 facilitates the installation of electrical components 27 of different sizes, offering high adaptability. The operator then moves the mounting bracket 16 to the innermost part of the distribution cabinet body 1 via the cooperation of the slider 17 and the sliding rod 13. The limiting rod 20 is then inserted through the limiting groove 15 and the limiting groove 19, enabling rapid positioning of the mounting bracket 16. During use, the operator rotates the cabinet door 2, causing it to contact the distribution cabinet body 1. Simultaneously, the soft magnet 5 and the soft magnet 8 attract each other, making the connection between the cabinet door 2 and the distribution cabinet body 1 tighter. This is especially important in humid environments. In case of humid conditions, to prevent humid air from entering the interior of the distribution cabinet 1 through the connection between the cabinet door 2 and the main body 1, which could damage the electrical components 27 and affect the normal operation of the entire unit, the system features a high degree of sealing. Furthermore, the rubber ring has excellent sealing properties, and the design of the sealing ring 6 further enhances the overall sealing performance, resulting in high practicality. The design of the ventilation opening 28 facilitates air circulation inside the distribution cabinet 1, preventing the electrical components 27 from operating in a high-temperature environment for extended periods, thus extending their service life. The overall heat dissipation performance is also high. When electrical component 27 is being repaired, the operator pulls the limit rod 20 out of the limit slot 15 and the limit slot 29. Then, the mounting bracket 16 is moved to the front of the distribution cabinet body 1 through the cooperation of the slider 17 and the sliding rod 13. Then, the limit rod 20 is passed through the limit slot 15 and the limit slot 29 at the other end of the fixing rod 21, which can realize the quick positioning of the mounting bracket 16. When repairing electrical component 27, the operator does not need to put their hands into the inside of the distribution cabinet body 1 to operate. The operating space is large, which makes it convenient for the operator to carry out the repair and the repair efficiency is high.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
