Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, and in particular to a highly adaptable and easy-to-install low-voltage switchgear. Background Technology

[0002] A low-voltage switchgear is an electrical device used in low-voltage power distribution systems to receive, distribute, and control electrical energy. It is mainly suitable for AC 50Hz power systems with a rated voltage of 1000V and below. It consists of multiple low-voltage electrical components assembled in a closed or semi-closed metal cabinet according to a certain circuit scheme, and is widely used in power distribution systems in industrial, commercial, and civil buildings.

[0003] In the existing technology, the electrical components installed inside conventional low-voltage switchgear are mounted on mounting racks, and the position of the mounting racks is fixed and cannot be adjusted. Therefore, when different numbers or sizes of electrical components need to be installed, the space becomes compact, resulting in a low-voltage switchgear being able to install only a certain type and size of electrical components. Utility Model Content

[0004] In view of this, the present invention provides a highly adaptable and easy-to-install low-voltage switchgear. The main technical problem to be solved is that the mounting bracket inside the low-voltage switchgear cannot be adjusted in position, which results in the compact internal space of the low-voltage switchgear when it is necessary to install large electrical components, making it unsuitable for installing large-sized electrical components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highly adaptable and easy-to-install low-voltage switchgear, comprising a cabinet body, a cabinet door installed on the outer wall of the cabinet body, brackets fixedly connected to both sides of the interior of the cabinet body, multiple insertion holes opened inside the brackets, a mounting frame slidably connected between two brackets, an adjustment component installed inside the mounting frame, the adjustment component comprising a gear one, the gear one being rotatably connected inside the mounting frame, a rotating shaft being rotatably connected inside the mounting frame, a gear two being fixedly connected to the outer wall of the rotating shaft, the gear two being meshed with the gear one, insertion rods being threaded to both ends of the rotating shaft, the insertion rods being slidably connected inside the mounting frame, and the insertion rods being slidably connected inside the insertion holes.

[0006] By adopting the above technical solution, the toothed part of gear one is turned in the forward direction, causing gear one to rotate and drive gear two and the rotating shaft to rotate. The rotation of the rotating shaft causes the two plug rods to slide to both sides, causing the plug rods to slide and engage inside the plug hole, thereby realizing the installation of the mounting bracket between the two supports. When the position of the mounting bracket needs to be adjusted, the toothed part of gear one is turned in the reverse direction, causing gear one to drive gear two and the rotating shaft to rotate, thereby causing the two plug rods to slide into the mounting bracket and disengage from the plug hole. Then, the height of the mounting bracket is adjusted, and gear one is turned in the forward direction again, causing the plug rods to slide into the plug hole, thus installing the mounting bracket between the two supports.

[0007] As a further description of the above technical solution: multiple mounting plates are installed on the outer wall of the mounting frame, and the mounting plates and the mounting frame are fixedly connected by bolts.

[0008] By adopting the above technical solution, different sizes of mounting plates can be replaced when different sizes of electrical components need to be installed.

[0009] As a further description of the above technical solution: electrical components are installed on the outer wall of the mounting plate, and the electrical components and the mounting plate are fixedly connected by bolts.

[0010] By adopting the above technical solution, electrical components are mounted on the outer wall of the mounting plate with bolts.

[0011] As a further description of the above technical solution: two dust covers are installed on the right side of the outer wall of the cabinet, and the two dust covers are fixedly connected to the cabinet by bolts.

[0012] By adopting the above technical solution, the dust cover is installed on the right outer wall of the cabinet, which serves to prevent dust and also assists in the heat dissipation of the cabinet.

[0013] As a further description of the above technical solution: a dustproof net is fixedly connected to the inside right side of the dustproof cover, two fans are installed inside the cabinet, and the dustproof cover is set on the outer wall of the fans.

[0014] By adopting the above technical solution, the dustproof net blocks dust and prevents it from entering the cabinet. The fan starts to promote airflow inside the cabinet, achieving a heat dissipation effect.

[0015] As a further description of the above technical solution: two dustproof nets are fixedly connected to the inside left side of the cabinet, and the dustproof nets correspond to the position of the fan.

[0016] By adopting the above technical solution, the dustproof netting effectively blocks dust and prevents it from entering the cabinet.

[0017] By employing the above technical solution, the highly adaptable and easy-to-install low-voltage switchgear of this utility model has at least the following beneficial effects:

[0018] Compared with existing technologies, this highly adaptable and easy-to-install low-voltage switchgear utilizes a set of gear one, a rotating shaft, gear two, and plug rods. When the position of the mounting bracket needs to be adjusted, the teeth of gear one are reversed, causing gear one to rotate and drive gear two and the rotating shaft to rotate. This, in turn, causes the two plug rods to slide inward into the mounting bracket, disengaging them from the sockets. The mounting bracket is then moved up and down to adjust its position. After adjustment, the plug rods are aligned with the corresponding sockets. Gear one is then reversed, causing gear one to drive gear two and the rotating shaft to rotate, causing the two plug rods to slide outward into the sockets. This completes the position adjustment of the mounting bracket. Furthermore, the number of mounting brackets can be selected according to the actual number of electrical components to be installed. Position adjustment is achieved through the mounting brackets, and the spacing between the mounting brackets can be adjusted according to the size of the electrical components to prevent the installation space from being too compact and affecting the use of the electrical components.

[0026] Reference Figure 1-5This utility model provides a highly adaptable and easy-to-install low-voltage switchgear, comprising a cabinet body 1, a cabinet door 101 installed on the outer wall of the cabinet body 1, brackets 2 fixedly connected to both sides of the interior of the cabinet body 1, multiple insertion holes 201 opened inside the brackets 2, a mounting frame 3 slidably connected between two brackets 2, the mounting frame 3 being limited to slide on the outer wall of the two brackets 2, an adjustment component 4 installed inside the mounting frame 3, the adjustment component 4 including a gear 401, the gear 401 being rotatably connected inside the mounting frame 3, the gear 401 being limited to rotate inside the mounting frame 3, a rotating shaft 402 being rotatably connected inside the mounting frame 3, a gear 403 being fixedly connected to the outer wall of the rotating shaft 402, the gear 403 being limited to be set in the mounting frame 3. Inside, gear 2 403 meshes with gear 1 401. Both ends of the rotating shaft 402 are threaded with insert rods 404. Threaded grooves are symmetrically opened at both ends of the rotating shaft 402. Two insert rods 404 are symmetrically arranged on the outer wall of the rotating shaft 402. The insert rods 404 are slidably connected to the inside of the mounting bracket 3. The insert rods 404 are limited to slide inside the mounting bracket 3. The insert rods 404 are slidably connected to the inside of the insertion hole 201. The insert rods 404 are limited to slide inside the insertion hole 201. Multiple mounting plates 301 are installed on the outer wall of the mounting bracket 3. The mounting plates 301 and the mounting bracket 3 are fixedly connected by bolts. Electrical components 302 are installed on the outer wall of the mounting plates 301. The electrical components 302 and the mounting plates 301 are fixedly connected by bolts.

[0027] Two dust covers 102 are installed on the right side of the outer wall of the cabinet 1. The two dust covers 102 are fixedly connected to the cabinet 1 by bolts. A dustproof net 103 is fixedly connected to the right side of the inside of the dust cover 102. Two fans 104 are installed inside the cabinet 1. The dust cover 102 is set on the outer wall of the fan 104. The dust cover 102 covers one side of the outer wall of the fan 104. When the fan 104 is turned on to dissipate heat from the inside of the cabinet 1, the dust cover 102 plays a protective role. Together with the dustproof net 103, it blocks the dust from entering the inside of the cabinet 1. Two dustproof nets 105 are fixedly connected to the left side of the inside of the cabinet 1. The dustproof nets 105 are corresponding to the positions of the fans 104.

[0028] Working principle: When a larger electrical component 302 needs to be installed, the number of mounting brackets 3 is selected according to the actual number of components to be installed. Smaller mounting plates 301 installed on the outer wall of the mounting bracket 3 can be removed and replaced with larger mounting plates 301 to facilitate the installation of larger electrical components 302. Then, the electrical component 302 can be installed on the outer wall of the mounting plate 301. The spacing between the mounting brackets 3 is adjusted according to the size of the electrical component 302. Reverse gear 401 is turned, causing it to rotate and drive gear 403 and the rotating shaft 402 to rotate. This, in turn, causes the two insertion rods 404 to slide into the mounting bracket 3, disengaging them from the insertion holes 201. At this point, the mounting bracket 3 can be moved up and down, causing the electrical components installed on its outer wall to move. Components 302 move together. After adjusting the position of the mounting bracket 3 to a suitable position, the first gear 401 is turned forward, causing the first gear 401 to drive the second gear 403 and the rotating shaft 402 to rotate. This causes the two insert rods 404 to slide to both sides and insert into the corresponding insertion holes 201 inside the two brackets 2, thus fixing the mounting bracket 3 between the two brackets 2. The mounting bracket 3 can not only be adjusted in position by adjusting the component 4, but also be disassembled and assembled by adjusting the component 4. After the first gear 401 slides out of the insertion hole 201, the mounting bracket 3 can be removed from between the two brackets 2. The number of mounting brackets 3 can be adjusted according to the actual number of electrical components 302 installed to ensure that the space inside the cabinet 1 is suitable for installing and using larger electrical components 302.
