[0026] This embodiment provides a water diversion structure for a cable distribution box. The cable distribution box includes a box body 1, a first box door 11 and a second box door 12 which are hinged to the box body 1 and are oppositely arranged. A waterproof diversion device is arranged on the first box door 11 or the second box door 12. A clamping opening 2 for the first box door 11 and the second box door 12 to be inserted into is arranged on the waterproof diversion device. The waterproof diversion device includes a first diversion strip 3 and a second diversion plate 4 which are arranged in an array. The clamping opening 2 is located on the side of the first diversion strip 3 facing away from the second diversion plate 4. The second diversion plate 4 is arranged along the height direction of the first box door 11 and the second box door 12. A diversion groove 5 for guiding water outwards is arranged between the first diversion strip 3 and the second diversion plate 4.
[0027] The above specific improvement is as follows: Figures 1-4As shown, the first box door 11 and the second box door 12 are hinged to the box body 1, and the first box door 11 and the second box door 12 can be opened from the middle to both sides. The applicant has obtained through experience that the general positions where rainwater enters are mostly at the connection positions between the box body 1 and the first box door 11 and the second box door 12 or at the contact positions of the first box door 11 and the second box door 12. Compared with the prior art, a waterproof diversion device is fixed on the first box door 11. The waterproof diversion device includes a first diversion strip 3 and a second diversion plate 4. A clamping opening 2 is provided on the side of the first diversion plate facing the first box door 11 and the second box door 12. When the first box door 11 and the second box door 12 are closed, partial positions of the first box door 11 and the second box door 12 will be embedded into the clamping opening 2. When rainwater enters from the first box door 11 and the second box door 12, the rainwater will fall into the diversion groove 5 and then flow downward along the second diversion plate 4. If the rainwater flows in from the connection position of the first box door 11 and the second box door 12, the rainwater will flow outwards along the direction of the clamping opening 2 and finally gather at the bottom of the first box door 11 and the second box door 12 and flow out. In this way, it is superior to the prior art. The waterproof diversion structure is made of metal material. Even after long-term use, it can ensure the waterproof effect of the box body 1 and prevent rainwater from entering the box body 1, thereby causing damage to the electrical equipment inside the box body 1.
[0028] Based on the above embodiment: The diversion groove 5 is communicated with the second diversion plate 4. The second diversion plate 4 includes a first extension strip 41, a second extension strip 42, and a connecting plate 43 arranged between the first extension strip 41 and the second extension strip 42. A "[" - shaped structure is formed by enclosing between the first extension strip 41, the second extension strip 42, and the connecting plate 43. The first diversion strip 3 is arranged inside the second diversion plate 4. The first diversion strip 3 includes a first support strip 31, a second support strip 32, and a connecting strip 33 arranged between the two. The clamping opening 2 is located between the first support strip 31 and the second support strip 32.
[0029] The above specific improvement is: Such as Figure 4 And Figure 5As shown, when the first door 11 and the second door 12 are in the closed state, the first support bar 31 and the first extension bar 41 will be stuck in the first door 11 and abut against the first door 11, the second support bar 32 and the second extension bar 42 will be stuck in the second door 12 and abut against the second door 12, and the side edges of the first door 11 and the second door 12 will be embedded in the card opening 2 and abut against the card opening 2. In this way, not only can the first door 11 and the second door 12 be quickly closed in place (abutment means that they are already closed in place), so that there will not be an excessively large gap between the first door 11, the second door 12 and the box body 1, but also rainwater entering from the gap between the first door 11 and the second door 12 can drip into the guide groove 5, and then flow out from top to bottom through the guide groove 5 along the setting direction of the second guide plate 4, so as to prevent rainwater from entering the box body 1 and affecting the circuit in the box body 1.
[0030] On the basis of the above embodiment: two first guide bars 3 are provided and are respectively located at the upper and lower ends of the second guide plate 4 .
[0031] On the basis of the above embodiment: both upper and lower ends of the box body 1 are provided with embedding grooves 6 for the first guide strip 3 to be inserted into.
[0032] The above specific improvements are: Figure 2 and Figure 6 As shown, the height of the first guide bar 3 is higher than that of the second guide plate 4, and embedded grooves 6 are provided at the upper and lower ends of the box body 1. The first guide bars 3 are also provided at the upper and lower ends of the second guide plate 4. When the first box door 11 and the second box door 12 are closed, the protruding part of the first guide bar 3 can be embedded in the embedded groove 6, which can not only quickly close the first box door 11 and the second box door 12 in place, but also the rainwater in the guide groove 5 can flow downward along the second guide plate 4, enter the embedded groove 6 at the lower end of the box body 1, and then flow out from the embedded groove 6, so that the rainwater can be effectively discharged and prevented from entering the interior of the box body 1.
[0033] On the basis of the above embodiment: a first card slot 7 is provided on the first box door 11, a second card slot 8 is provided on the second box door 12, the first extension strip 41 and the first support strip 31 can be inserted into the first card slot 7, and the second extension strip 42 and the second support strip 32 can be inserted into the second card slot 8.
[0034] The above specific improvements are: Figure 4As shown, in order to make the connection between the first box body 1 and the second box door 12 and the box body 1 tighter, a first card slot 7 is set in the first box door 11, and a second card slot 8 is set in the second box door 12. When the first box door 11 and the second box door 12 are closed, the first extension bar 41 and the first support bar 31 can be inserted into the first card slot 7 and abut against the first card slot 7, and the second extension bar 42 and the second support bar 32 can be inserted into the second card slot 8 and abut against the second card slot 8, thereby effectively extending the path for rainwater to enter the box body 1 and improving the waterproof performance of the box body 1.
[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
