Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switch cabinets, in particular to a door frame baffle structure on a low-voltage switch cabinet. Background Art

[0002] The door frame baffle on the low-voltage switch cabinet plays an important role. During use, it can prevent the operator from accidentally touching the live parts inside the switch cabinet during operation, thereby reducing the risk of electric shock. When the door frame baffle is at the bottom, it can prevent small animals such as snakes, rats, and insects from crawling into the low-voltage switch cabinet. When the staff is working with water, the door frame baffle can effectively prevent water from entering the switch cabinet, avoiding short circuits caused by water ingress to internal components. However, when in use, the existing door frame baffles are mostly set as a sliding structure without a limit assembly. The door frame baffle is easy to loosen and slide, and cannot play a shielding and protective role. In addition, there is a gap between the bottom of the door frame baffle and the cabinet body. The water blocked by the door frame baffle can easily flow into the interior of the switch cabinet through the gap, and the cabinet door collides with the cabinet body when closing, generating noise. In addition, due to frequent opening and closing, it is easy to be deformed and damaged. In order to solve the above problems, a door frame baffle structure on the low-voltage switch cabinet is needed.

[0003] The existing door frame baffle structure on the low-voltage switch cabinet has poor fixing effect during operation, resulting in poor connection stability, inability to be hydrophobic and waterproof, and inability to provide buffering and noise reduction protection. Therefore, a door frame baffle structure on the low-voltage switch cabinet is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the present utility model is to provide a door frame baffle structure on a low-voltage switch cabinet to solve the problem that the door frame baffle structure on the existing low-voltage switch cabinet has poor fixing effect during use, resulting in poor connection stability, inability to be hydrophobic and waterproof, and inability to provide buffering and noise reduction protection.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a door frame baffle structure on a low-voltage switch cabinet, which is installed on a distribution cabinet body, wherein a cabinet door is installed on the outer wall of the distribution cabinet body, a control switch is installed on the inner wall of the distribution cabinet body, slide rails are installed on the inner walls of both sides of the distribution cabinet body, a baffle is installed on the inner wall of the slide rail, a reset spring is installed on the inner wall of the baffle, a limit rod is installed on the outer wall of the reset spring, a heat dissipation net is installed on the inner wall of the baffle, and a handle is installed on the outer wall of the baffle.

[0006] The outer wall of the slide rail is installed with a positioning plate, the inner wall of the positioning plate is installed with a limiting shaft, the outer wall of the limiting shaft is installed with a limiting spring, the outer wall of the limiting shaft is installed with a protective rubber sleeve, and the outer wall of the positioning plate is installed with a limiting sleeve.

[0007] A front protective plate is installed on the inner wall of the bottom of the power distribution cabinet, and a drain hole is opened on the inner wall of the front protective plate. A rear protective plate is installed on the inner wall of the bottom of the power distribution cabinet.

[0008] Preferably, the slide rail is engaged with a limit rod, and the limit rod forms a telescopic structure with the shielding plate through a return spring.

[0009] Preferably, the shielding plate is slidably connected to the slide rail, and the handle is symmetrically arranged with the central axis of the shielding plate as the center.

[0010] Preferably, the limiting shaft forms a telescopic structure with a limiting spring and a positioning plate, and the limiting shaft is sleeved with a protective rubber sleeve.

[0011] Preferably, the limiting shaft is movably connected to the limiting sleeve, and the protective rubber sleeve fits tightly against the cabinet door.

[0012] Preferably, the hydrophobic holes are distributed at equal intervals with the central axis of the front protective plate as the center, and the top surface of the rear protective plate is higher than the top surface of the front protective plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model is provided with a slide rail, a shielding plate, a return spring, a limit rod, a heat dissipation net and a handle. The position of the shielding plate is adjusted by pulling the handle. When the shielding plate moves to a specified position, the limit rod is pushed out by the elastic force of the return spring and is fixed to the slide rail, so that the shielding plate is prevented from loosening and falling off during maintenance work, thereby losing its protective function. In addition, the provision of the heat dissipation net can improve the heat dissipation effect inside the distribution cabinet, and the utility model is highly practical.

[0015] The utility model provides a positioning plate, a limit shaft, a limit spring, a protective rubber sleeve and a limit sleeve. When the cabinet door is closed, the cabinet door collides with the distribution cabinet body to generate noise. Frequent opening and closing can easily cause deformation or damage to the distribution cabinet body and the cabinet door, affecting the safety of its use. The setting of the limit shaft can buffer and absorb the deformation of the limit spring when the cabinet door is closed, thereby reducing the impact force of the cabinet door. The protective rubber sleeve fits tightly with the cabinet door, reducing the noise when the cabinet door is closed. The coordinated use of the limit shaft, the limit spring and the protective rubber sleeve can extend the service life of the distribution cabinet body and the cabinet door.

[0016] The utility model has a front protective plate, drain holes and a rear protective plate. When a worker working with water inspects and repairs the control switch, the shielding plate blocks scattered water stains, and the water stains fall through the surface of the shielding plate and are discharged through the drain holes on the inner wall of the front protective plate. Moreover, the rear protective plate is higher than the front protective plate. Even if the shielding plate is moved upward and withdrawn, the water stains cannot flow into the distribution cabinet due to the obstruction of the rear protective plate, thereby improving the safety of the control switch operation.
