DETAILED DESCRIPTION

[0015] The utility model will be further explained in detail through specific implementation ways as follows:

[0016] As shown in the figures, Figure 1 , Figure 2 and Figure 3 An air exchange louver linkage system for a power distribution box is provided in the embodiments of the utility model, which comprises a mounting frame 1 and multiple louver leaves 2 arranged in the mounting hole on the inner side of the mounting frame 1, the multiple louver leaves 2 are all rotationally connected with the mounting frame 1, an adjusting knob 3 is rotationally arranged on the outer wall of the mounting frame 1, a mounting cavity is opened in the mounting frame 1, a transmission assembly 4 is arranged in the mounting cavity and connected between the adjusting knob 3 and each louver leaf 2, and the transmission assembly 4 is used to drive the multiple louver leaves 2 to synchronously rotate to open or close the mounting hole when the adjusting knob 3 is rotated.

[0017] ​The ventilation shutter is rotated by holding the adjusting knob 3 when the distribution box is running, the plurality of shutter leaves 2 are synchronously rotated by the transmission assembly 4, the mounting hole is opened, and the heat generated by the distribution box is quickly dissipated through the mounting hole at this time; when the distribution box stops running, the adjusting knob 3 is reversely rotated, the plurality of shutter leaves 2 are synchronously reversely rotated by the transmission assembly 4, the mounting hole is closed, and dust and flying insects are prevented from entering the distribution box from the mounting hole; the adjusting process is convenient and fast.

[0018] In order to better understand the scheme, the transmission assembly 4 and the like will be optimized below.

[0019] As shown in Figure 1 , Figure 2 and Figure 3 , according to another embodiment of the utility model, the ventilation shutter linkage system for the distribution box, wherein the transmission assembly 4 includes a plurality of transmission wheels 41 and a transmission belt 42, the plurality of transmission wheels 41 are arranged in the mounting cavity, and each of the plurality of transmission wheels 41 is connected to one of the plurality of shutter leaves 2, wherein one of the plurality of transmission wheels 41 is connected to the adjusting knob 3 through the adjusting part; the transmission belt 42 is connected between the plurality of transmission wheels 41, and two matched compression wheels 43 are arranged between each adjacent two transmission wheels 41, the two matched compression wheels 43 are arranged on the outer side of the transmission belt 42 and slide against the transmission belt 42 to form a transmission angle between each transmission wheel 41 and the transmission belt 42.

[0020] In this embodiment, when adjusting, the adjusting knob 3 is rotated, the adjusting knob 3 drives the transmission wheel 41 connected thereto to rotate through the adjusting part, and then drives the other transmission wheels 41 to rotate through the cooperation of the transmission belt 42 and the two matched compression wheels 43 between each adjacent two transmission wheels 41, so as to drive the plurality of shutter leaves 2 to rotate, thereby opening or closing the mounting hole.

[0021] The distance between the two matched compression wheels 43 is less than the diameter of the transmission wheel 41, that is, the two compression wheels 43 fold the section of the transmission belt 42 between the adjacent two transmission wheels 41 to the middle part, so that the transmission belt 42 forms a suitable transmission angle on each transmission wheel 41, and each transmission wheel 41 can rotate during the operation of the transmission belt 42, and then the plurality of shutter leaves 2 can rotate to open or close the mounting hole.

[0022] In this embodiment, the transmission wheel 41 can be a belt wheel, and the transmission belt 42 is a belt; the transmission wheel 41 can also be a sprocket, and the transmission belt 42 is a chain; preferably, the transmission wheel 41 is a sprocket, and the transmission belt 42 is a chain, so that the plurality of transmission wheels 41 and the transmission belt 42 can be more stably transmitted.

[0023] AsFigure 2 As shown, according to another embodiment of the present invention, the ventilation louver linkage system for a power distribution box includes an adjustment unit comprising a transmission bevel gear 44 and a drive bevel gear 45. The transmission bevel gear 44 is coaxially connected to a corresponding transmission wheel 41. The drive bevel gear 45 meshes with the transmission bevel gear 44 and is also coaxially connected to the adjustment knob 3.

[0024] During adjustment:

[0025] Hold the adjustment knob 3 and turn it. The drive bevel gear 45 rotates synchronously with the adjustment knob 3. The drive bevel gear 45 drives the transmission bevel gear 44 to rotate. The transmission bevel gear 44 drives the transmission wheel 41 connected to it to rotate. Then, through the transmission belt 42 and the two pressure rollers 43 that cooperate between each pair of adjacent transmission wheels 41, the other transmission wheels 41 are driven to rotate. This drives the multiple louver blades 2 to rotate, so as to open or close the mounting holes.

[0026] It should be noted that the adjustment knob 3, transmission component 4, and multiple louver blades 2 can all remain stationary when not adjusted due to the friction they experience after installation and the self-locking force after assembly.

[0027] To improve the stability of the multiple louver slats 2 remaining stationary after adjustment, the adjustment knob 3 is coaxially connected to the drive bevel gear 45 via a connecting shaft. The adjustment knob 3 is slidably attached to the outer wall of the mounting frame 1. The connecting shaft is fitted with an annular magnet embedded in the mounting frame 1. An iron block (not shown in the attached figure) is embedded in the side of the adjustment knob 3 facing the mounting frame 1 to cooperate with the annular magnet.

[0028] In the above-described manner, without rotating the adjustment knob 3, the interaction between the ring magnet and the iron block creates a magnetic attraction force that locks the adjustment knob 3 in place. Since the adjustment knob 3 will not rotate, the transmission assembly 4 and the multiple louver blades 2 can stably maintain their positions. The arrangement of the ring magnet and iron block is such that, after rotating the adjustment knob 3, the iron block can engage with the ring magnet to form a magnetic attraction force. It should be noted that even when the adjustment knob 3 needs to be rotated, the resistance generated by this magnetic attraction force is relatively small.

[0029] like Figure 1 and Figure 4 As shown, according to another embodiment of the present utility model, the ventilation louver linkage system for the distribution box is provided, wherein the edge of the mounting frame 1 is provided with a plurality of locking rotating parts 5 that correspond one-to-one with a plurality of locking grooves opened on the inner wall of the mounting position on the distribution box.

[0030] The ventilation shutter is installed by embedding the mounting frame 1 into the corresponding installation position on the distribution box, abutting, and then rotating the plurality of locking knobs 5, one by one, into the plurality of locking grooves, thereby quickly and stably installing the ventilation shutter in the corresponding installation position on the distribution box. When disassembly is required, the plurality of locking knobs 5 are rotated in the opposite direction, and the plurality of locking knobs 5 are rotated out of the plurality of locking grooves, the mounting frame 1 is released from the lock, and then the ventilation shutter can be removed from the corresponding installation position on the distribution box.

[0031] Based on the above scheme:

[0032] Each locking knob 5 includes a locking block 51, a handle 52, an abutting block 53, and a locking cap 54. The locking block 51 is rotatably connected to the outer wall edge of the mounting frame 1 at one end and is used to rotate into the corresponding locking groove for limiting at the other end. An installation groove is formed on the side of the locking block 51 away from the mounting frame 1. The handle 52 is inserted into the installation groove along the depth direction of the installation groove to be fixedly connected. The abutting block 53 is slidably sleeved on the handle 52, and a plurality of springs are connected between the abutting block 53 and the inner wall of the installation groove. The locking cap 54 is threadedly connected with the handle 52 and abuts against the abutting block 53.

[0033] In the initial state, the locking cap 54 abuts against the abutting block 53, and the abutting block 53 is completely embedded in the installation groove. When the ventilation shutter needs to be installed in the corresponding installation position on the distribution box, the following steps are performed:

[0034] First, ensure that the locking block 51 in each locking knob 5 is attached to the outer edge of the outer side of the mounting frame 1, so as to avoid being blocked when the mounting frame 1 is embedded in the corresponding installation position on the distribution box;

[0035] Then, the mounting frame 1 is embedded in the corresponding installation position on the distribution box and abuts;

[0036] Next, the handle 52 in each locking knob 5 is held and rotated, and the locking block 51 in the plurality of locking knobs 5 is rotated into the plurality of locking grooves, one by one;

[0037] Then, the locking cap 54 in each locking knob 5 is rotated, the locking cap 54 moves away from the corresponding abutting block 53, the locking cap 54 releases the restriction on the abutting block 53, the plurality of springs in each locking knob 5 are expanded, the abutting block 53 moves away from the corresponding locking block 51, the abutting block 53 abuts against the inner wall of the corresponding locking groove, and the locking knob 5 is stably assembled in the locking groove.

[0038] When the ventilation shutter needs to be disassembled:

[0039] First, rotate the locking cap 54 in each locking knob 5, and the corresponding block 53 is moved to the direction of the corresponding locking block 51 until the block 53 is completely embedded in the corresponding installation slot;

[0040] Then, hold the handle 52 in each locking knob 5 to rotate, and move the one end of the locking block 51 in the plurality of locking knobs 5 from the plurality of locking slots;

[0041] Then, the installation frame 1 can be removed from the corresponding installation position on the distribution box.

[0042] Finally, it should be pointed out that the above examples are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
