Description

Technical Field

[0001] This utility model relates to the field of low-voltage cabinet technology, specifically to a low-voltage cabinet structure. Background Technology

[0002] Low-voltage cabinets are primarily used for the unified management of low-voltage signal lines such as telephone, broadband, television, audio, video, camera, security, and access control systems. These lines operate at low voltages, typically below 36V. The low-voltage cabinet enables centralized management and distribution of these signals, preventing messy wiring and mutual interference, while also facilitating future maintenance and upgrades.

[0003] Existing low-voltage cabinets generally consist of a cabinet body and a cabinet door. To ensure ventilation and heat dissipation, ventilation slots are usually provided on the side walls of the cabinet body. However, as the low-voltage cabinet is used over time, dust accumulates on the outer surface of the ventilation slots. Therefore, it is necessary to clean the dust on the outer surface of the ventilation slots regularly. In the current technology, users usually use brushes or other cleaning tools to sweep and clean the dust on the outer surface of the ventilation slots. However, during the cleaning process, a lot of dust will enter the cabinet body through the ventilation slots, which will affect the use of the internal components. Utility Model Content

[0004] The purpose of this utility model is to provide a cabinet structure for low-voltage electrical control to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A low-voltage cabinet structure includes a cabinet frame and a top seat and a base located at the upper and lower ends of the cabinet frame. The cabinet frame is provided with an assemblable mounting component for installing components inside the low-voltage cabinet. The top seat has a top cavity that connects to the cabinet frame. The left and right side walls of the top seat are provided with ventilation grooves that connect to the top cavity. Filter screens are embedded in the left and right side walls of the top seat at the ventilation grooves. A sealing component is provided in the top cavity to seal the ventilation grooves so that the filter screen can be brushed and cleaned.

[0006] Preferably, the mounting components include horizontal beams opposite each other on the left and right side walls of the cabinet, opposite vertical beams between the horizontal beams, a liftable partition between the vertical beams, an adjustable strip plate between the vertical beams in front of the partition, and an adjustable mounting back frame between the horizontal beams at the bottom of the cabinet.

[0007] Preferably, the left and right side walls of the top seat are provided with recessed grooves corresponding to the ventilation grooves, and the filter screen is embedded in the recessed grooves.

[0008] Preferably, the sealing assembly includes a movable sealing plate, and the side of the sealing plate facing the corresponding vent groove is provided with a protrusion that can be inserted into the corresponding vent groove. The sealing plate is also provided with a strip groove. The sealing assembly also includes a drive unit for driving the sealing plate to conform to or move away from the sidewall of the corresponding top cavity.

[0009] Preferably, a baffle is provided in the top cavity and at the four corners. A positioning rod is provided between the baffle and the side wall of the top cavity, passing through the four corners of the sealing plate. The two ends of the sealing plate are bent to form a bent plate. The driving component includes an elastic element provided between the bent plate and the side wall of the top cavity. The elastic element is used to drive the sealing plate away from the side wall of the corresponding top cavity.

[0010] Preferably, the driving component also includes a mounting cylinder disposed in the top cavity along the front-rear direction, a pushing block that can move along the mounting cylinder, a first guide surface on the side wall of the pushing block, a fixing block that cooperates with the pushing block on the sealing plate, a second guide surface that cooperates with the first guide surface on the fixing block, the pushing block moves to the rear side of the cabinet so that the first guide surface presses against the second guide surface, and pushes the sealing plate to fit against the corresponding side wall of the top cavity.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0023] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0024] like Figure 1 As shown, a low-voltage cabinet structure in this embodiment includes a cabinet frame 110 and a top seat 120 and a base 130 located at the upper and lower ends of the cabinet frame 110. The cabinet frame 110 is provided with an assemblable installation component, which is used to install components in the low-voltage cabinet. In this embodiment, combined with Figure 2 and Figure 3 As shown, the cabinet frame 110 is column-shaped. The top seat 120 is fixedly installed on the top of the cabinet frame 110 by bolts, and the base 130 is fixedly installed on the bottom of the cabinet frame 110 by bolts. Side panels 112 are installed on the left, right and rear sides of the cabinet frame 110. The front side of the cabinet frame 110 is hinged to an openable cabinet door 111. Specifically, the side panels 112 are installed on the cabinet frame 110 by screws. Thus, a low-voltage cabinet is preferably formed, making the assembly of the low-voltage cabinet more convenient. Among them, combined Figure 4As shown, the top seat 120 has a top cavity 401 that connects to the cabinet frame 110. The left and right side walls of the top seat 120 are provided with ventilation grooves 402 that connect to the top cavity 401. The left and right side walls of the top seat 120 and the ventilation grooves 402 are embedded with filter screens 121. Specifically, in order to realize the installation of filter screens 121, the left and right side walls of the top seat 120 are provided with recessed grooves 403 corresponding to the ventilation grooves 402, and the filter screens 121 are embedded in the recessed grooves 403. The top cavity 401 is provided with a sealing component, which is used to seal the ventilation grooves 402 so that the filter screens 121 can be brushed and cleaned.

[0025] In this embodiment, during the use of the low-voltage cabinet, the sealing component is released from the venting groove 402, allowing the low-voltage cabinet to ventilate and dissipate heat normally using the venting groove 402 and the filter screen 121. During long-term use of the low-voltage cabinet, dust will adhere to the outer surface of the filter screen 121, affecting its ventilation and heat dissipation. At this time, the venting groove 402 is closed by the sealing component. Then, the user uses a brush to clean the filter screen 121 from the outside of the low-voltage cabinet, so that the filter screen 121 is clean. During this process, the dust swept by the brush is not likely to enter the interior of the low-voltage cabinet through the venting groove 402, so as not to affect the use of its internal components.

[0026] In this embodiment, the installation assembly includes crossbeams 310 disposed on the left and right side walls of the cabinet frame 110. In actual use, the crossbeams 310 can be made of channel steel and are fixedly installed on the left and right inner side walls of the cabinet frame 110 by bolts. Multiple crossbeams 310 are provided and are evenly distributed along the height direction of the cabinet frame 110. Opposite vertical beams 320 are provided between the crossbeams 310. The vertical beams 320 can be made of channel steel and are also fixedly installed between the crossbeams 310 by bolts. Specifically, opposite vertical beams 320 are provided on both the front and rear sides of the cabinet frame 110. The vertical beams 320 are equipped with liftable partitions 330. Specifically, the side walls of the vertical beams 320 are provided with several mounting holes along their height direction. The four corners of the partitions 330 are bent to form mounting parts, which are connected to the corresponding mounting holes by screws to realize the installation of the partitions 330 between the vertical beams 320. The partitions 330 are used for the installation of components such as fiber optic boxes and switches. The vertical beams 320 on the front side of the partitions 330 are equipped with adjustable strip plates 340. Specifically, the strip plates 340 are connected to the corresponding mounting holes by screws to realize the installation of the strip plates 340. An adjustable mounting back frame 350 is provided between the crossbeams 310 at the bottom of the cabinet 110. Specifically, several through holes are arranged along the length of the side wall of the crossbeam 310. The mounting back frame 350 is installed between the crossbeams 310 by bolts. It is used to install components such as patch panels. The mounting back frame 350 uses bolts to connect the through holes at different positions so that the position of the mounting back frame 350 relative to the front side of the cabinet 110 is adjustable for its actual use.

[0027] In this embodiment, a cavity (not shown in the figure) is provided inside the base 130. A wire hole 201 communicating with the cavity is provided on the upper side of the base 130. A wiring groove (not shown in the figure) for leading wire harnesses out of the low-voltage cabinet is provided on the rear side of the base 130. The wire hole 201 and the wiring groove enable external wire harnesses to be introduced into the low-voltage cabinet and connected to the internal components, and enable wire harnesses connected to the components to be led out of the low-voltage cabinet.

[0028] Combination Figure 5 and Figure 6 As shown, in this embodiment, the sealing assembly includes a movable sealing plate 410. The sealing plate 410 has a protrusion 601 on its side facing the corresponding vent 402 that can be inserted into the corresponding vent 402. The sealing plate 410 also has a strip groove 602, wherein the strip groove 602 is set to avoid the protrusion 601. The sealing assembly also includes a drive unit for driving the sealing plate 410 to conform to or move away from the sidewall of the corresponding top cavity 401.

[0029] In this embodiment, in order to improve the sealing effect when the sealing plate 410 is in contact with the side wall corresponding to the top cavity 401, a sealing gasket is provided on the side of the sealing plate 410 facing the corresponding vent groove 402, which is in contact with the side wall corresponding to the top cavity 401. In this embodiment, the sealing plate 410 is moved away from the side wall corresponding to the top cavity 401 by the driving component, so that the gas in the top cavity 401 can flow with the gas outside the weak current cabinet under the action of the strip groove 602 and the venting groove 402, thereby allowing the weak current cabinet to be ventilated and dissipated. When the driving component makes the sealing plate 410 fit against the side wall corresponding to the top cavity 401, the venting groove 402 is sealed on the inside of the top cavity 401. At the same time, the protrusion 601 extends into the venting groove 402 to prevent dust from entering the venting groove 402 for temporary storage when the brush sweeps the filter screen 121, so as to reduce the amount of dust entering the weak current cabinet from the venting groove 402 after brushing and cleaning.

[0030] In order to enable the sealing plate 410 to be slidably installed in the top cavity 401, in this embodiment, a baffle 404 is provided in the top cavity 401 and at the four corners. A positioning rod 520 is provided between the baffle 404 and the side wall of the top cavity 401, which passes through the four corners of the sealing plate 410. By sliding the positioning rod 520 through the four corners of the sealing plate 410, the sealing plate 410 can be guided and positioned, making the movement more stable, so that the protrusion 601 can extend into or out of the ventilation groove 402. The two ends of the sealing plate 410 are bent to form a bent plate 603. The driving component includes an elastic member 610 provided between the bent plate 603 and the side wall of the top cavity 401. The elastic member 610 is used to drive the sealing plate 410 away from the corresponding side wall of the top cavity 401, that is, to enable the weak current cabinet to have normal ventilation and heat dissipation.

[0031] Among them, the elastic element 610 can be a spring. In order to ensure the stable installation of the spring, a protrusion is provided on the bending plate 603. The spring is sleeved on the protrusion, with one end abutting against the bending plate 603 and the other end abutting against the side wall of the top cavity 401, so that the spring is installed and pushes the sealing plate 410 away from the corresponding side wall of the top cavity 401.

[0032] To facilitate the user's movement of the sealing plate 410 outside the low-voltage cabinet, in this embodiment, combined with... Figure 7 As shown, the driving component also includes a mounting cylinder 420 disposed in the top cavity 401 along the front-rear direction. A pushing block 530 is disposed outside the mounting cylinder 420 and can move along it. A first guide surface 721 is disposed on the side wall of the pushing block 530. A fixing block 511 that cooperates with the pushing block 530 is fixedly disposed on the sealing plate 410. A second guide surface that cooperates with the first guide surface 721 is disposed on the fixing block 511. The pushing block 530 moves to the rear side of the cabinet frame 110 so that the first guide surface 721 presses the second guide surface, pushing the sealing plate 410 to fit against the corresponding side wall of the top cavity 401.

[0033] In this embodiment, a sliding groove 701 is provided on the side wall of the mounting cylinder 420 along its axial direction, and a sliding block 710 is provided inside the mounting cylinder 420. The sliding block 710 is connected to the push block 530 through a slider 711 passing through the sliding groove 701. A screw 140 extending into the mounting cylinder 420 is threaded on the front side of the top seat 120.

[0034] In actual use, by rotating the screw 140 to extend it into the mounting cylinder 420, it pushes the sliding block 710 inside to move towards the rear of the low-voltage cabinet. During this process, the pushing block 530 moves backward, causing the first guide surface 721 on it to press against the second guide surface, thereby pushing the sealing plate 410 to move to fit against the side wall of the top cavity 401. During this process, the elastic element 610 is compressed. When the screw 140 is rotated to extend it out of the mounting cylinder 420, the pushing of the screw 140 on the sliding block 710 is released. At this time, the compressed elastic element 610 is reset, causing the sealing plate 410 to move away from the corresponding side wall of the top cavity 401. With the cooperation of the second guide surface and the first guide surface 721, the sliding block 710 and the pushing block 530 move forward along the mounting cylinder 420 to reset, so that they can drive the sealing plate 410 to fit against the corresponding side wall of the top cavity 401 again. It should be noted that when the push block 530 moves to the last side of the mounting cylinder 420 until the sealing plate 410 is in contact with the side wall corresponding to the top cavity 401, the first guide surface 721 remains in contact with the second guide surface to prevent the push block 530 from sliding away from the fixed block 511, which would prevent it from driving the sealing plate 410 to move.

[0035] In order to facilitate the user to rotate the screw 140, a screw cap is fixedly provided on the outer end of the screw 140.

[0036] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
