Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and more specifically, to a distribution box with an installation height adjustment function. Background Art

[0002] A distribution box is a low-voltage distribution box that is assembled in accordance with electrical wiring requirements by assembling switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Currently, most distribution boxes are fixed box structures, which are not convenient for flexible adjustment according to the height during installation. The patent document with the prior art publication number CN118017375A provides a distribution box with an installation height adjustment function. The device can adjust the distance and height between the device and the installation top seat by adjusting the screw during installation, thereby adjusting the overall installation height of the device, making the device more flexible during installation.

[0003] In view of the above-mentioned related technologies, the inventor believes that the device is set on the top of the box body through screws and mounting top seats, which occupies a large space and is inconvenient during transportation and storage. In addition, the overall stability is poor because the mounting top seats are used to fix the entire device. Therefore, we propose a distribution box with a mounting height adjustment function. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a distribution box with an installation height adjustment function, which adopts the following technical solutions:

[0005] A distribution box with an installation height adjustment function includes a distribution box main body, and also includes two fixing plates fixedly installed on the back of the distribution box main body, a positioning rod is fixedly connected to the fixing plate, a mounting plate is provided on one side of the distribution box main body, the mounting plate is plugged into the positioning rod, a plurality of mounting holes are provided on the mounting plate, limit rods are elastically connected on both sides of the mounting plate, the limit rods are engaged with a toothed plate clamp fixedly connected to the positioning rod, and a bidirectional screw is rotatably connected to the mounting plate, and the bidirectional screw is used to drive the limit rod to move.

[0006] By adopting the above technical solution, the rotation of the bidirectional screw can drive the two limit rods to slide closer to or away from each other. When the limit rod is not engaged with the tooth plate, the mounting plate and the positioning rod can slide, thereby adjusting the height of the distribution box body. After the limit rod is engaged with the tooth plate, the height of the distribution box body can be fixed.

[0007] Optionally, grooves are provided on the sides of the two positioning rods that are away from each other, and positioning plates are fixedly connected to both ends of the mounting plate, and the positioning plates are plugged into and fit in the grooves of the positioning rods.

[0008] By adopting the above technical solution, the positioning plate and the positioning rod are plugged in and matched so that the mounting plate and the distribution box can be quickly disassembled, so that the mounting plate and the mounting point can be fixed first, and then the distribution box body can be connected to the mounting plate, thereby improving installation convenience.

[0009] Optionally, the end of the limit rod is elastically connected to the mounting plate via a spring A;

[0010] Two sliders are threadedly connected on the bidirectional screw rod, the sliders are slidably connected to the mounting plate, and the sliders are hinged to the limit rod through a connecting rod.

[0011] By adopting the above technical solution, when the bidirectional screw rotates, the two sliders move away from or approach each other, so that the limit rod is driven to engage with the tooth plate or cancel the engagement with the tooth plate. When the two sliders approach each other, the spring A can drive the limit rod to cancel the engagement with the tooth plate.

[0012] Optionally, one end of the bidirectional screw is fixedly connected to a driving block, and the driving block is provided with a hexagonal groove.

[0013] By adopting the above technical solution, the bidirectional screw can be driven to rotate after the hexagonal wrench tool is connected to the driving block.

[0014] Optionally, two brake blocks that are engaged with each other are sleeved on the bidirectional screw, one of the brake blocks is fixedly connected to the bidirectional screw, and the other brake block is slidably connected to the mounting plate and elastically connected to the mounting plate via a spring B.

[0015] By adopting the above technical solution, when the spring B drives the lower brake block to rise and engage with the upper brake block, the rotation of the bidirectional screw can be limited, thereby improving the stability of the connection between the mounting plate and the distribution box body.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. By placing the mounting plate on the north side of the distribution box body, the occupied space can be reduced, and the height of the distribution box body can be adjusted by sliding the positioning rod and the mounting plate. Then, by rotating the bidirectional screw to drive the limit rod and the tooth plate to engage, the mounting plate and the distribution box body can be stably connected, easy to operate, and have good stability.

[0018] 2. After the two brake blocks are locked by spring B, the rotation of the bidirectional screw can be restricted, thereby further improving the connection stability between the mounting plate and the distribution box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-4 The present application includes a distribution box body 1, and also includes two fixing plates 2 fixedly installed on the back of the distribution box body 1, and a positioning rod 3 is fixedly connected to the fixing plate 2. A mounting plate 4 is provided on one side of the distribution box body 1, and the mounting plate 4 is plugged into and matched with the positioning rod 3. A plurality of mounting holes 6 are opened on the mounting plate 4, and the mounting parts are installed and fixed to the mounting points by bolts and mounting holes. Limit rods 7 are elastically connected to both sides of the mounting plate 4, and the limit rods 7 are engaged with the toothed plate 8 fixedly connected to the positioning rod 3, and a bidirectional screw 10 is rotatably connected to the mounting plate 4, and the bidirectional screw 10 is used to drive the limit rod 7 to move. The rotation of the bidirectional screw 10 can drive the two limit rods 7 to slide closer to or away from each other. When the limit rod 7 is not engaged with the toothed plate 8, the mounting plate 4 can slide with the positioning rod 3, so that the height of the distribution box body 1 can be adjusted. After the limit rod 7 is engaged with the toothed plate 8, the height of the distribution box body 1 can be fixed.

[0026] Reference Figure 2 A groove is provided on the side where the two positioning rods 3 are away from each other, and positioning plates 5 are fixedly connected to both ends of the mounting plate 4. The positioning plates 5 are plugged into the grooves of the positioning rods 3. The plug-in cooperation between the positioning plates 5 and the positioning rods 3 allows the mounting plate 4 and the distribution box 1 to be quickly disassembled, so that the mounting plate 4 can be fixed to the mounting point first, and then the distribution box body 1 can be connected to the mounting plate 4, thereby improving the installation convenience.

[0027] Reference Figure 3The end of the limit rod 7 is elastically connected to the mounting plate 4 through a spring A9; two sliders 11 are threadedly connected to the bidirectional screw 10, the sliders 11 are slidably connected to the mounting plate 4, and the sliders 11 are hinged to the limit rod 7 through a connecting rod 12. When the bidirectional screw 10 rotates, the two sliders 11 move away from or approach each other, thereby driving the limit rod 7 to engage with or cancel the engagement with the tooth plate 8. When the two sliders 11 approach each other, the spring A9 can drive the limit rod 7 to cancel the engagement with the tooth plate 8.

[0028] Reference Figure 4 One end of the bidirectional screw 10 is fixedly connected to a driving block 13, and a hexagonal slot is provided on the driving block 13. After the hexagonal wrench tool is connected to the driving block 13, the bidirectional screw 10 can be driven to rotate.

[0029] Reference Figure 4 Two brake blocks 14 that are engaged with each other are sleeved on the bidirectional screw 10. One brake block 14 is fixedly connected to the bidirectional screw 10, and the other brake block 14 is slidably connected to the mounting plate 4 and elastically connected to the mounting plate 4 through a spring B15. When the spring B15 drives the lower brake block 144 to rise and engage with the upper brake block 14, the rotation of the bidirectional screw 10 can be limited, thereby improving the stability of the connection between the mounting plate 4 and the distribution box body 1.

[0030] A T-block is fixedly connected to the lower brake block 14 , and the T-block is slidably connected to the mounting plate 4 . When the T-block is pressed downward, the lower brake block 14 can be driven down so that the two brake blocks 14 are not in contact, and the bidirectional screw 10 can rotate.

[0031] The implementation principle of the distribution box with the installation height adjustment function in the embodiment of the present application is as follows: after the mounting plate 4 is installed and fixed with the mounting point through the mounting hole 6 and the mounting piece, the positioning rod 3 is plugged and matched with the positioning plate 5. After the distribution box body 1 is adjusted to an appropriate height, the T-block is pressed downward to drive the two brake blocks 14 to separate. The hexagonal wrench tool is connected to the driving block 13 to drive the bidirectional screw 10 to rotate. The two sliding blocks 11 move away from each other, so that the limit rod 7 is clamped with the tooth plate 8, so that the distribution box body 1 is connected and fixed with the mounting plate 4, and then the T-block is loosened to clamp the two brake blocks 14, and the rotation of the bidirectional screw 10 is limited.
