Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, specifically a switch cabinet with a sliding device. Background Technology

[0002] A switchgear is a type of electrical equipment. External power lines first enter the main control switch inside the cabinet, then proceed to the branch control switches. Each branch circuit is configured according to its needs, such as for instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments, and are equipped with high-voltage busbars, such as in power plants. Some also have underfrequency load shearing mechanisms to ensure the proper functioning of major equipment. When a switchgear is in use, electronic components are fixed to mounting plates inside the switchgear with bolts. When installing electronic components near the inner wall of the switchgear, the switchgear obstructs the movement, requiring installation tools such as screwdrivers to be tilted, which is time-consuming and laborious, making it inconvenient for installers to quickly install electronic components. For example, a sliding device and switchgear for a switchgear, as described in application number CN221900399U, includes a mounting plate with support sleeves slidably fitted on both sides. A fixed sleeve is fixedly connected to the bottom of the mounting plate. A rotating rod is provided inside the fixed sleeve, with both ends of the rotating rod extending through to the outside of the fixed sleeve and fixedly connected to a locking plate. A slot is formed at the bottom of the support sleeve, and the top of the locking plate extends into the slot. Sliding sleeves are fixedly connected to both sides of the back of the rotating rod. A movable plate is provided inside the fixed sleeve, with gears hinged to both sides of the movable plate via shafts. Sliding rods are fixedly connected to the surfaces of the gears. However, the sliding devices and switchgears of the above-mentioned common types of switchgear still have the following shortcomings in practical applications:

[0003] In daily frequent operation, dry friction between sliding devices generates heat. Prolonged friction exacerbates component wear and shortens their service life. Over time, sliding resistance increases, the operating feel becomes stiff, and even jamming may occur, affecting the timeliness and accuracy of operation. In case of an emergency, the inability to quickly and accurately operate the switchgear will seriously threaten the safe and stable operation of the power system. Moreover, excessively worn components may also cause loosening, displacement, and other problems, increasing the probability of failure and requiring frequent replacement of parts, thus increasing material costs. Utility Model Content

[0004] The purpose of this utility model is to provide a switchgear with a sliding device to solve the problems mentioned in the background art, such as the heat generated by dry friction between the sliding devices during frequent daily operation, the wear of components due to prolonged friction, the shortening of their service life, the increasing sliding resistance over time, the stiffening of the operation feel, and even the possibility of jamming, which affects the timeliness and accuracy of operation. In case of an emergency, the inability to operate the switchgear quickly and accurately will seriously threaten the safe and stable operation of the power system. Moreover, excessively worn components may also cause problems such as loosening and displacement, increasing the probability of failure and requiring frequent replacement of parts, which increases the cost of materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switch cabinet with a sliding device, comprising a cabinet body, heat dissipation holes on both sides of the cabinet body, a cabinet door hinged to the front of the cabinet body, a handle fixedly installed on the front of the cabinet door, four oil inlet holes fixedly installed on the back of the cabinet body, two support plates fixedly installed in the inner cavity of the cabinet body, and a sliding device fixedly installed on both sides of the two support plates, with a locking device slidably connected to the inner cavity of the sliding device.

[0006] Preferably, the sliding device includes a sliding groove, a sliding block is slidably connected to the inner cavity of the sliding groove, an oil storage tank is provided at the bottom of the sliding groove, and snap-fit ​​grooves are provided on both sides of the inner cavity of the sliding groove. A plurality of lubricating beads are rotatably arranged between the sliding groove and the oil storage tank, and an mounting plate is fixedly installed on the top of the two sliding blocks to facilitate lubrication of the sliding device through the lubricating beads.

[0007] Preferably, the locking device includes a pull rod and a support plate. One end of the pull rod has a slot, and the other end of the pull rod is fixedly connected to a tension band. Both sides of the top of the tension band are fixedly connected to locking blocks, and springs are sleeved on the outer rings of both sides of the tension band. The locking device can effectively lock and fix the sliding device.

[0008] Preferably, the top of the bearing plate is provided with a guide groove, and a bearing block is fixedly provided in the middle of the guide groove. One end of the two springs is fixedly connected to the bearing block, and the tension band slides in the inner cavity of the bearing block. The sliding of the tension band in the inner cavity of the bearing block can effectively retract the snap-fit ​​block.

[0009] Preferably, the two snap-fit ​​blocks correspond to the snap-fit ​​grooves, the oil inlet corresponds to the oil storage tank, and the pull rod and the bearing plate are installed in the inner cavity of the sliding block.

[0010] Preferably, each of the four corners of the bottom of the cabinet is fixedly equipped with casters, which can be used to move the cabinet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Lubricating oil is added to the oil storage tank through the oil inlet hole, and the lubricating beads are rotated by the sliding block, so that the lubricating oil can enter the sliding groove through the lubricating beads. This can effectively lubricate during sliding, effectively reduce the coefficient of friction, reduce friction force, and make the sliding operation easier and less strenuous. At the same time, good lubrication can reduce wear, reduce the probability of component damage, improve the reliability and stability of switch cabinet operation, reduce the power outage maintenance time caused by component failure, ensure the continuity of power supply, and improve the overall power supply efficiency and quality.

The sliding device includes a sliding groove 9. A sliding block 10 is slidably connected to the inner cavity of the sliding groove 9. An oil storage tank 12 is provided at the bottom of the sliding groove 9. Locking grooves 14 are provided on both sides of the inner cavity of the sliding groove 9. Several lubricating beads 13 are rotatably arranged between the sliding groove 9 and the oil storage tank 12. An mounting plate 5 is fixedly installed on the top of the two sliding blocks 10. Universal wheels 6 are fixedly installed at the four corners of the bottom of the cabinet body 1.

[0021] In this embodiment of the application, when in use, the oil inlet 7 is first connected to an external device to begin oil replenishment. The lubricating oil enters the oil storage tank 12 through the oil inlet 7. When the device needs to be installed, the locking device is used to release the fixation of the sliding block 10. Then, the sliding block 10 slides out in the sliding groove 9. During the sliding, the sliding groove 9 will drive the lubricating beads 13 to rotate, so that lubrication can be performed. After the electrical equipment is installed on the sliding block 10, the sliding block 10 slides back in the sliding groove 9 and is finally fixed by the locking device.

[0022] Please see Figure 1-6 Furthermore, the engaging device includes a pull rod 11 and a support plate 16. One end of the pull rod 11 has a slot 15, and the other end of the pull rod 11 is fixedly connected to a tension band 20.
