Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a dustproof power distribution box. Background Technology

[0002] A dustproof distribution box is an electrical equipment protection enclosure with dust barrier function. Its core function is to provide a closed protective space for internal electrical components such as circuit breakers, contactors, terminals, and frequency converters. It can not only realize the basic functions of power distribution, circuit control and safety protection, but also prevent external dust, lint, and particulate impurities from entering the box through a specific structural design. This avoids impurities adhering to the surface of electrical components, damaging insulation performance, hindering heat dissipation or causing short circuit faults, and ultimately ensures the stable operation of the electrical system in a dusty environment.

[0003] In the existing technology, the ventilation openings of dustproof distribution boxes are equipped with dustproof nets to intercept dust. Currently, the dustproof nets are mainly fixed by bolts. When disassembling, tools are needed to unscrew all the bolts one by one. However, the bolts are small and light, and are easy to fall off or be lost. This results in a lack of fasteners during reinstallation, which affects the installation of the dustproof nets. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the ventilation openings of traditional dustproof distribution boxes are equipped with dustproof nets to intercept dust. Currently, the dustproof nets are mainly fixed by bolts. When disassembling, tools are needed to unscrew all the bolts one by one. However, the bolts are small and light, and are easy to fall off or be lost. This results in a lack of fixing parts when reinstalling, which affects the installation of the dustproof nets. Therefore, the proposed dustproof distribution box is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof distribution box, including a box body, a fixing device on one side of the box body, an outer frame of the fixing device, one end of the outer frame being fixedly connected to the box body, a rubber frame inside the outer frame, a dustproof net being interference-fitted inside the rubber frame, two telescopic rods being fixedly connected to one side of the outer frame, an L-shaped plate being fixedly connected to the output ends of the two telescopic rods, a U-shaped limiting plate being fixedly connected to one side of the L-shaped plate, and one side of the U-shaped limiting plate being slidably connected to the outer frame.

[0006] The effect achieved by the above components is as follows: the L-shaped plate is pulled and moved away from the outer frame. At this time, the output end of the telescopic rod extends until it reaches its maximum extension. Then, the U-shaped limiting plate removes its restriction on the dustproof net and applies a pulling force to the dustproof net away from the outer frame, thus completing the disassembly of the dustproof net.

[0007] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the two springs are respectively fixedly connected to the L-shaped plate and the outer frame.

[0008] The effect achieved by the above components is that the spring sleeved on the telescopic rod can provide axial guidance for the telescopic rod.

[0009] Preferably, the L-shaped plate has a pull opening on one side, and the outer frame has side grooves on both sides.

[0010] The aforementioned components achieve the following effect: the side grooves are opened on the outer frame, and the pull tabs are opened on the L-shaped plate, which facilitates the application of force to the L-shaped plate.

[0011] Preferably, the side groove is slidably connected with round rods, and one end of the two round rods is fixedly connected to the L-shaped plate.

[0012] The effect achieved by the above components is that the movement of the L-shaped plate drives the round rod to slide in the side groove, thus preventing the L-shaped plate from shifting position during the movement.

[0013] Preferably, the arc surface of the round rod is fixedly connected to a fixing block, and the side of the two fixing blocks that are close to each other is fixedly connected to a U-shaped limiting plate.

[0014] The effect achieved by the above components is that the fixing block is fixed to the round rod and the U-shaped limiting plate.

[0015] Preferably, the bottom of the box is provided with a support device, the support device includes an I-shaped plate, one side of the I-shaped plate is fixedly connected to the box, and four threaded rods are fixedly connected to one side of the I-shaped plate.

[0016] The effect achieved by the above components is that the threaded rod is fixed to the I-shaped plate, and the I-shaped plate is fixed to the box body.

[0017] Preferably, the arc surface of the threaded rod is threadedly connected to an internal threaded cylinder, and one end of the internal threaded cylinder is fixedly connected to a base block.

[0018] The effect achieved by the above components is that the internal threaded cylinder rotates and moves on the threaded rod, so that the bottom block moves synchronously.

[0019] Preferably, one end of the base block is fixedly connected to an anti-slip block.

[0020] The effect achieved by the above components is to increase friction by preventing the slider from moving.

[0021] Preferably, the arc surface of the internally threaded cylinder is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the internally threaded cylinder.

[0022] The effect achieved by the above components is that the anti-slip grooves are opened on the internal threaded cylinder, thereby increasing the friction.

[0023] In summary, the beneficial effects of this utility model are as follows: In this invention, a fixing device is used to allow for easy disassembly and cleaning of the dustproof net. The L-shaped plate is pulled away from the outer frame, causing the telescopic rod to extend and the spring to stretch, thus disengaging the U-shaped limiting plate from the dustproof net. The dustproof net is then pulled away from the rubber frame for removal. After cleaning or replacement, the process is reversed for installation. This fixing device solves the problem of traditional dustproof distribution boxes having dustproof nets at their ventilation openings to intercept dust. Currently, these nets are mainly fixed with bolts, requiring tools to unscrew them one by one during disassembly. However, these small and light bolts are prone to falling off or being lost, resulting in a lack of fasteners during reinstallation and hindering the installation of the dustproof net.

[0024] In this invention, when the height of the enclosure needs to be adjusted, the operator first rotates the inner threaded cylinder of the support leg to be adjusted, causing it to move upward or downward along the threaded rod axis, thereby adjusting the vertical distance between the bottom block and the I-shaped plate installed at the bottom of the enclosure. During the adjustment process, the anti-slip block moves synchronously with the bottom block and always keeps in contact with the ground, ensuring stable support of the enclosure. Through the support device, the problem of the fixed height of the support legs of traditional dustproof distribution boxes, which leads to unstable placement of the enclosure if there is a height difference on the installation ground, is solved.

[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a dustproof power distribution box, including a box body 1, a fixing device 2 on one side of the box body 1, and a supporting device 3 at the bottom of the box body 1.

[0028] The following section will describe the specific setup and function of its fixing device 2 and supporting device 3.

[0029] Reference Figure 2 and Figure 3 As shown in this embodiment: the fixing device 2 has an outer frame 201, one end of which is fixedly connected to the housing 1. A rubber frame 202 is provided inside the outer frame 201, and a dustproof net 203 is interference-fitted inside the rubber frame 202. Two telescopic rods 204 are fixedly connected to one side of the outer frame 201. An L-shaped plate 206 is fixedly connected to the output end of the two telescopic rods 204. A U-shaped limiting plate 207 is fixedly connected to one side of the L-shaped plate 206, and one side of the U-shaped limiting plate 207 is slidably connected to the outer frame 201. This achieves the effect of pulling the L-shaped plate 206, causing it to move away from the outer frame 201. At this time, the output end of the telescopic rod 204 extends until it reaches its maximum extension. Then, the U-shaped limiting plate 207 releases its restriction on the dustproof net 203, and a pulling force is applied to the dustproof net 203 in a direction away from the outer frame 201, thus completing the disassembly of the dustproof net 203. Springs 205 are fitted onto the arc surface of the telescopic rod 204. The two ends of the two springs 205 are fixedly connected to the L-shaped plate 206 and the outer frame 201, respectively. This ensures that the springs 205, fitted onto the telescopic rod 204, provide axial guidance. A pull opening 208 is provided on one side of the L-shaped plate 206, and side grooves 210 are provided on both sides of the outer frame 201. The side grooves 210 are located on the outer frame 201, and the pull opening 208 is located on the L-shaped plate 206, facilitating the application of force to the L-shaped plate 206. Round rods 209 are slidably connected inside the side grooves 210, with one end of each round rod 209 fixedly connected to the L-shaped plate 206. This ensures that the movement of the L-shaped plate 206 causes the round rods 209 to slide within the side grooves 210, preventing the L-shaped plate 206 from shifting position during movement. A fixing block 211 is fixedly connected to the arc surface of the round rod 209, and the side of the two fixing blocks 211 that are close to each other is fixedly connected to the U-shaped limiting plate 207. This achieves the effect of fixing the fixing block 211 to the round rod 209 and the U-shaped limiting plate 207.

[0030] Reference Figure 4 As shown in this embodiment: the support device 3 includes an I-shaped plate 31, one side of which is fixedly connected to the housing 1, and four threaded rods 32 are fixedly connected to one side of the I-shaped plate 31. This achieves the effect of the threaded rods 32 being fixed to the I-shaped plate 31, and the I-shaped plate 31 being fixed to the housing 1. An internally threaded cylinder 33 is threadedly connected to the arc surface of the threaded rod 32, and a base block 34 is fixedly connected to one end of the internally threaded cylinder 33. This achieves the effect of the internally threaded cylinder 33 rotating and moving on the threaded rod 32, causing the base block 34 to move synchronously. An anti-slip block 35 is fixedly connected to one end of the base block 34. This achieves the effect of the anti-slip block 35 increasing friction. Several anti-slip grooves 36 are evenly distributed on the arc surface of the internally threaded cylinder 33. This achieves the effect of the anti-slip grooves 36 increasing friction.

[0031] Working principle: Using the fixing device 2, when the dustproof net 203 needs to be disassembled and cleaned, the operator first pulls the L-shaped plate 206 away from the outer frame 201. During this process, the output end of the telescopic rod 204 extends synchronously with the movement of the L-shaped plate 206, and the spring 205 is gradually stretched. After the output end of the telescopic rod 204 extends to its maximum stroke, the U-shaped limiting plate 207 will disengage from the dustproof net 203. At this time, pulling the dustproof net 203 away from the outer frame 201 will allow the dustproof net 203 to detach from the rubber frame 202 and complete the disassembly. After the dustproof net 203 is cleaned or replaced with a new one, the above steps are reversed to achieve the desired result. When the dustproof net 203 is reinstalled and the L-shaped plate 206 is moved, the round rod 209 will slide along the side groove 210 preset on the outer frame 201. Through the guiding cooperation between the round rod 209 and the side groove 210, the L-shaped plate 206 can be effectively prevented from shifting position during movement, ensuring stable and smooth disassembly and assembly. Through the fixing device 2, the problem of dustproof nets 203 being installed at the ventilation openings of traditional dustproof distribution boxes to intercept dust is solved. Currently, the dustproof nets 203 are mainly fixed by bolts. When disassembling, tools are needed to unscrew all the bolts one by one. However, the bolts are small and light, and are easy to fall off or be lost, resulting in a lack of fixing parts during reinstallation, which affects the installation of the dustproof net 203.

[0032] With the support device 3, when the height of the box 1 needs to be adjusted, the operator first rotates the inner threaded cylinder 33 of the support foot to be adjusted, so that it moves upward or downward along the threaded rod 32 axis, thereby adjusting the vertical distance between the bottom block 34 and the I-shaped plate 31 installed at the bottom of the box 1. During the adjustment process, the anti-slip block 35 moves synchronously with the bottom block 34 and always keeps in contact with the ground, ensuring that the box 1 is stably supported. With the support device 3, the problem of the fixed height of the support feet of the traditional dustproof distribution box is solved, which leads to the unstable placement of the box 1 if there is a height difference on the installation ground.
