Description

Technical Field

[0001] This utility model relates to the technical field of instrument mounting boxes, specifically a layered electrical instrument mounting box. Background Technology

[0002] Instrument boxes generally include components such as outer shell, panel, lining, and bracket. They are widely used in industries such as instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, and precision machinery, and mainly serve to protect the components.

[0003] Layered waterproof electrical instrument installation boxes are commonly used electrical equipment on the market. They have internal partitions to achieve layering. For example, Chinese utility model patent application number 202220136438.2 discloses "a layered waterproof electrical instrument installation box", which uses a series of springs to achieve shock resistance and uses an anti-interference layer to achieve anti-interference of the instrument box.

[0004] However, current layered waterproof electrical instrument installation boxes lack auxiliary instrument heat dissipation components, making it difficult to reduce the heat generated during instrument operation, thereby reducing the performance of internal instruments and, in severe cases, the possibility of them burning out.

[0005] Based on this, this solution proposes a layered electrical instrumentation box. Utility Model Content

[0006] The purpose of this utility model is to provide a layered electrical instrument mounting box to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a layered electrical instrument mounting box, including a mounting box,

[0008] The front end of the mounting box is hinged with a door, and heat dissipation boxes are fixedly installed on both sides of the mounting box adjacent to the door. Multiple ventilation holes are opened on the side of the two heat dissipation boxes that are far apart from each other, and ventilation holes are opened between the two heat dissipation boxes and the mounting box.

[0009] The mounting box has two first sliding rods and a fixed rod fixedly installed inside. Three layered plates are slidably sleeved on the two first sliding rods. Mounting holes are opened on both sides of the top of any layered plate. Positioning screws are rotatably installed on the inner walls of both sides of any mounting hole. An L-shaped clamping plate is threaded onto any positioning screw. The same worm gear is fixedly sleeved between two positioning screws located in the same mounting hole.

[0010] A worm is rotatably installed in any of the mounting holes, and each worm meshes with a corresponding worm wheel. A knob is fixedly sleeved at one end of each worm.

[0011] The fixing rod is provided with multiple limiting grooves at equal intervals along the vertical direction, and a limiting bolt is threaded onto any of the layered plates;

[0012] Two reciprocating gears are rotatably installed inside each of the two heat sinks. A connecting rod is fixedly installed on each of the reciprocating gears, and a cooling fan is fixedly installed on each of the connecting rods.

[0013] Preferably, the mounting box is equipped with casters at all four corners of its bottom.

[0014] The above technical solution utilizes casters to facilitate the movement of the entire device.

[0015] Preferably, the threads of the two positioning screws located in the same mounting hole are set in opposite directions.

[0016] By adopting the above technical solution and through the above settings, the two L-shaped clamping plates located in the same mounting hole can move in opposite directions.

[0017] Preferably, two slide rails are fixedly installed in each mounting hole, and a slider is slidably installed on each slide rail. Each slider is fixedly connected to the corresponding L-shaped clamping plate.

[0018] The above technical solution facilitates the movement of the L-shaped clamping plate through the slide rail and slider.

[0019] Preferably, a handle is fixedly installed on the outside of the box door.

[0020] The above technical solution allows for easy opening of the cabinet door via a handle.

[0021] Preferably, each of the two heat sinks has a rotating shaft rotatably mounted inside, and each of the two heat sinks has a second sliding rod fixedly mounted inside. A half gear and a sprocket are fixedly sleeved on each rotating shaft, and the same chain is sleeved between the two sprockets. Two sliding sleeves are slidably sleeved on the two sliding rods, and a reciprocating rack and a linkage rack are fixedly mounted on each sliding sleeve. Each reciprocating gear meshes with the corresponding reciprocating rack. A motor is fixedly mounted at the front end of the corresponding heat sink, and the output shaft of the motor is fixedly connected to the corresponding rotating shaft.

[0022] Using the above technical solution, the starter motor drives the corresponding sprocket to rotate. Through the linkage of the chain, both sprockets rotate simultaneously, which in turn drives both half gears to rotate simultaneously. The half gears intermittently mesh with the corresponding two linkage racks, which in turn drive the corresponding two linkage racks to move up and down reciprocatingly. This, in turn, drives the corresponding two sliding sleeves to move up and down reciprocatingly, which in turn drives the corresponding two reciprocating racks to move up and down reciprocatingly. The reciprocating racks drive the corresponding reciprocating gears and connecting rods to rotate back and forth, which in turn drives the corresponding cooling fan to rotate back and forth. This allows for uniform, large-area air cooling and heat dissipation of the interior of the mounting box, increasing the heat dissipation efficiency.

[0023] Preferably, each of the second sliding rods is fixedly connected to a corresponding sliding sleeve with a return spring.

[0024] By adopting the above technical solution, the return spring facilitates the reset of the sliding sleeve.

[0025] Preferably, both heat dissipation boxes are fitted with dust filters and dryer filters.

[0026] By adopting the above technical solution, the dust filter and the dryer filter can reduce the amount of dust and moisture from the outside entering the interior of the installation box.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: By adjusting the position of the layered plates vertically and then tightening the inward rotating limiting bolts so that the limiting bolts are engaged in the corresponding limiting grooves, the height of the layered plates can be locked and fixed. Then, the electrical instruments are placed between the two corresponding L-shaped clamping plates. By rotating the corresponding knob, the corresponding worm gear is rotated, which in turn rotates the corresponding worm wheel, which in turn rotates the two corresponding positioning screws. This causes the two corresponding L-shaped clamping plates to move towards each other, thus clamping and fixing the corresponding electrical instruments. Because a large amount of heat will be generated inside the mounting box during prolonged use, timely heat dissipation and cooling are required. This can be achieved by activating four heat dissipation devices. A hot air fan cools the interior of the mounting box. To enhance the cooling effect, a motor drives a sprocket, which, through chain linkage, rotates two sprockets simultaneously, driving two half-gears. These half-gears intermittently mesh with two corresponding racks, causing them to reciprocate up and down. This, in turn, causes two sliding sleeves to reciprocate up and down, which in turn causes two reciprocating racks to reciprocate. The reciprocating racks then drive the reciprocating gears and connecting rods, which in turn drive the cooling fan. This provides uniform, large-area air cooling to the interior of the mounting box, increasing cooling efficiency. This invention is simple in structure and easy to use. The layered electrical instrument mounting box allows for the fixed installation of layered electrical instruments and provides large-area cooling through its reciprocating structure, extending the lifespan of the instruments.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5This utility model provides a technical solution: a layered electrical instrument mounting box, including a mounting box 1. A door 2 is hinged to the front end of the mounting box 1, and heat dissipation boxes 3 are fixedly installed on both sides of the mounting box 1 adjacent to the door 2. A handle 4 is fixedly installed on the outer side of the door 2. Multiple ventilation holes 8 are opened on the side of the two heat dissipation boxes 3 that are far apart from each other, and ventilation holes are opened between the two heat dissipation boxes 3 and the mounting box 1. Two first sliding rods 26 and a fixed rod 14 are fixedly installed inside the mounting box 1. Three layered plates 13 are slidably sleeved on the two first sliding rods 26. Mounting holes 30 are opened on both sides of the top of any layered plate 13. Positioning screws 7 are rotatably mounted on the inner walls of both sides of the mounting hole 30. The threads of the two positioning screws 7 located in the same mounting hole 30 are set in opposite directions. An L-shaped clamping plate 29 is threaded onto each positioning screw 7. Two slide rails are fixedly mounted in each mounting hole 30. A slider is slidably mounted on each slide rail. Each slider is fixedly connected to the corresponding L-shaped clamping plate 29. The same worm gear 25 is fixedly sleeved between the two positioning screws 7 located in the same mounting hole 30. A worm 28 is rotatably mounted in each mounting hole 30. Each worm 28 meshes with the corresponding worm gear 25. In this configuration, a knob 31 is fixedly fitted to one end of each worm gear 28. Multiple limiting grooves 15 are evenly spaced along the vertical direction on the fixing rod 14. A limiting bolt 32 is threaded onto each layer plate 13. Two reciprocating gears 19 are rotatably installed inside each of the two heat sinks 3. A connecting rod 18 is fixedly installed on each reciprocating gear 19, and a cooling fan 16 is fixedly installed on each connecting rod 18. With this structural configuration, the position of the layer plate 13 can be adjusted vertically. Then, by tightening the rotating limiting bolt 32 inwards, the limiting bolt 32 is engaged into the corresponding limiting groove 15, thus adjusting the position of the layer plate 13. The height is locked and fixed, and then the electrical instrument is placed between the two corresponding L-shaped clamping plates 29. Then, by rotating the corresponding knob 31, the corresponding worm gear 28 is rotated, the worm gear 28 drives the corresponding worm wheel 25 to rotate, and the worm wheel 25 drives the two corresponding positioning screws 7 to rotate, which drives the two corresponding L-shaped clamping plates 29 to move towards each other, thereby clamping and fixing the corresponding electrical instrument. During long-term use, a lot of heat will be generated inside the mounting box 1, which needs to be cooled down in time. This can be done by starting the four cooling fans 16 to cool down the inside of the mounting box 1.

[0036] Combination Figure 1-5 As shown, casters 5 are rotatably mounted on the four corners of the bottom of the mounting box 1. Through the above-mentioned structural arrangement, the casters 5 facilitate the movement of the entire device.

[0037] Combination Figure 1-5As shown, each of the two heat sinks 3 has a rotating shaft 23 rotatably installed inside, and each of the two heat sinks 3 has a second slide rod 17 fixedly installed inside. A half gear 24 and a sprocket 9 are fixedly sleeved on each of the rotating shafts 23. The same chain 10 is sleeved between the two sprockets 9. Two sliding sleeves 21 are slidably sleeved on the two slide rods 17. A reciprocating rack 27 and a linkage rack 22 are fixedly installed on each of the sliding sleeves 21. Each reciprocating gear 19 meshes with the corresponding reciprocating rack 27. A motor 6 is fixedly installed at the front end of the corresponding heat sink 3. The output shaft of the motor 6 is fixedly connected to the corresponding rotating shaft 23. A return spring 20 is fixedly sleeved between each of the second slide rods 17 and the corresponding sliding sleeve 21. Dust filters 11 and dry filters 12 are engaged and installed inside each of the two heat sinks 3. Through the above structural settings, the dust filters 11 and dry filters 12 can reduce the entry of external dust and moisture into the interior of the mounting box 1.

[0038] The working principle of this utility model is as follows: The position of the layered plate 13 can be adjusted vertically, and then the limiting bolt 32 can be tightened inward to lock it into the corresponding limiting groove 15, thus locking the height of the layered plate 13. Then, the electrical instrument is placed between the two corresponding L-shaped clamping plates 29. Rotating the corresponding knob 31 drives the corresponding worm gear 28, which in turn drives the corresponding worm wheel 25. The worm wheel 25 then drives the two corresponding positioning screws 7, causing the two L-shaped clamping plates 29 to move towards each other, thus clamping and fixing the electrical instrument. During prolonged use, the inside of the mounting box 1 generates a large amount of heat, requiring timely heat dissipation and cooling. This can be achieved by starting the four cooling fans 16. For internal heat dissipation and cooling of the mounting box 1, to enhance the cooling effect, the starting motor 6 drives the corresponding sprocket 9 to rotate. Through the linkage of the chain 10, both sprockets 9 rotate simultaneously, which in turn drives both half-gears 24. The half-gears 24 indirectly mesh with the corresponding two linkage racks 22, causing the racks 22 to move up and down reciprocally. This, in turn, causes the two sliding sleeves 21 to move up and down reciprocally, which in turn causes the two reciprocating racks 27 to move up and down reciprocally. The reciprocating racks 27 then drive the reciprocating gears 19 and connecting rods 18 to rotate back and forth, which in turn drives the cooling fan 16 to rotate back and forth. This provides uniform, large-area air-cooled heat dissipation and cooling of the interior of the mounting box 1, increasing the cooling efficiency. This utility model has a simple structure and is easy to use. The layered electrical instrument mounting box described herein can achieve the fixed installation of layered electrical instruments and, through the reciprocating structure, provides large-area heat dissipation and cooling of the electrical instruments within the mounting box, increasing the service life of the electrical instruments.
