Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a waterproof and dustproof distribution box. Background Art

[0002] The distribution box is a general circuit distribution box for all users' electricity consumption. For outdoor distribution boxes, it is necessary to ensure that the inside of the distribution box has sufficient waterproof and dustproof performance to ensure the safety of the distribution box. In the structural design of traditional outdoor distribution boxes, the side opposite to the door panel of the frame is set as a flat surface, and an annular rubber ring is arranged on the frame or the flat plate. When the door panel is closed, the annular rubber ring is squeezed by the frame and the door panel to achieve buffering and sealing. However, in a long-term rainy environment, a small amount of rainwater still leaks in from the upper part where the door panel and the frame are connected. In the long run, the filling performance of the annular rubber ring will be reduced, resulting in a further reduction in the dustproof effect. Therefore, the waterproof and dustproof effect of the distribution box is not good.

[0003] In view of this, it is necessary to provide a waterproof and dustproof distribution box. Summary of the Invention

[0004] The waterproof and dustproof distribution box provided by the utility model effectively solves the problem of poor waterproof and dustproof effects of existing distribution boxes.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A waterproof and dustproof distribution box includes a frame, a door panel hinged to the frame, and a locking member arranged on the door panel. The frame includes a first plate corresponding to the door panel and four side plates respectively arranged on four sides of the first plate. Industrial sockets are arranged on the side plates, and the four side plates are hermetically connected. The door panel includes a plate body and a first bending portion arranged on four sides of the plate body. The frame further includes a second bending portion formed by bending the end of the side plate. An annular rubber ring is arranged on the plate body, and the annular rubber ring can abut against the end of the second bending portion. A dehumidifier is also arranged inside the side plate. The first bending portion forms a first annular groove with the notch facing inwards, and the second bending portion forms a second annular groove with the notch facing outwards. The notch of the first annular groove is opposite to the notch of the second annular groove.

[0007] Furthermore, the first bending portion includes a fifth plate bent from the end of the plate body toward one side of the side plate and a sixth plate bent from the end of the fifth plate toward the inner side of the side plate. The second bending portion includes a second plate integrally formed with the side plate and parallel to the first plate, a third plate bent from the end of the second plate, and a fourth plate bent from the end of the third plate. The second plate extends toward the inner side of the side plate, the third plate extends perpendicularly away from the first plate, and the fourth plate extends parallel to the outer side of the side plate. The sixth plate and the fourth plate do not overlap in the front-back direction projection. When the door panel is in the closed state with the frame, the sixth plate abuts against the second plate, and the fourth plate abuts against the annular rubber ring.

[0008] Furthermore, the industrial socket is a PKF screw-connecting and installing italic industrial socket.

[0009] Furthermore, horizontal hanging angle braces are symmetrically arranged on both sides of the first plate, and a plurality of mounting holes are vertically arranged on the horizontal hanging angle braces.

[0010] Furthermore, a plurality of wire tying bridges are arranged on the first plate. The wire tying bridge includes a fixing portion fixedly connected to the first plate and a bridge-shaped block connected to the fixing portion. The bridge-shaped block and the fixing portion form a wire passing hole.

[0011] Advantages of the utility model: The gap between the plate body and the second bending portion is filled with an annular rubber ring to seal the distribution box, achieving waterproof and dustproof effects. By setting a dehumidifier, the water vapor inside the distribution box can be effectively removed, ensuring the dryness of the entire distribution box and achieving waterproof and dustproof effects.

[0018] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings.

[0019] As Figure 1 , Figure 3 and Figure 4 shown, a waterproof and dustproof distribution box provided by an embodiment of the present application has a structure including a frame 1, a door panel 2 hinged to the frame 1, and a locking member 7 provided on the door panel 2. The frame 1 includes a first plate 11 corresponding to the door panel 2 and four side plates 12 respectively arranged on four sides of the first plate 11. An industrial socket 3 is provided on the side plate 12, and the four side plates 12 are hermetically connected. The door panel 2 includes a plate body 21 and a first bending portion 22 arranged on four sides of the plate body 21. The frame 1 further includes a second bending portion 13 formed by bending the end of the side plate 12. An annular rubber ring 8 is provided on the plate body 21, and the annular rubber ring 8 can abut against the end of the second bending portion 13. A dehumidifier 4 is further provided inside the side plate 12. The first bending portion 22 forms a first annular groove 200 with the notch facing inwards, and the second bending portion 13 forms a second annular groove 100 with the notch facing outwards. The notch of the first annular groove 200 is opposite to the notch of the second annular groove 100.

[0020] During actual use, when the door panel 2 is closed along the hinge and then the door panel 2 is locked to the frame 1 through the locking member 7, in the locked state, the second bending portion 13 abuts against the annular rubber ring 8, and the annular rubber ring 8 is compressed to fill the gap between the plate body 21 and the second bending portion 13. When the distribution box is used for a long time, the dehumidifier 4 removes the water vapor inside the distribution box. When the distribution box is exposed to rain for a long time, rainwater enters the second annular groove 100 through the gap between the door panel 2 and the frame 1 and then naturally flows from the upper end of the second annular groove 100 to the lower end and drips. The annular rubber ring 8 will not be eroded by rainwater during the whole process.

[0021] In the above design, the gap between the plate body 21 and the second bending part 13 is filled with an annular rubber ring 8 to seal the distribution box. The rainwater is diverted through the second annular groove 100 to ensure that the annular rubber ring 8 is not eroded by rainwater. By setting a dehumidifier 4, the water vapor in the distribution box can be effectively removed to ensure the dryness inside the entire distribution box, achieving waterproof and dustproof functions.

[0022] Specifically: As Figure 4 shown, the first bending part 22 includes a fifth plate 221 bent from the end of the plate body 21 towards the side plate 12 and a sixth plate 222 bent from the end of the fifth plate 221 towards the inside of the side plate 12. The second bending part 13 includes a second plate 131 integrally formed with the side plate 12 and parallel to the first plate 11, a third plate 132 bent from the end of the second plate 131, and a fourth plate 133 bent from the end of the third plate 132. The second plate 131 extends towards the inside of the side plate 12. The third plate 132 extends vertically away from the first plate 11. The fourth plate 133 extends parallel to the outside of the side plate 12. The projections of the sixth plate 222 and the fourth plate 133 in the front-back direction do not overlap. When the door panel 2 and the frame 1 are in the closed state, the sixth plate 222 abuts against the second plate 131, and the fourth plate 133 abuts against the annular rubber ring 8.

[0023] During actual use, when the door panel 2 and the frame 1 are closed, the sixth plate 222 abuts against the second plate 131, and the fourth plate 133 abuts against the annular rubber ring 8. At this time, an avoidance and space alignment are formed between the first bending part 22 and the second bending part 13. The second annular groove 100 formed by the second bending part 13 can collect and divert a small amount of rainwater leaking from the first bending part 22, effectively preventing rainwater from entering the distribution box.

[0024] In the above design, the structural design and specific implementation of the first bending part 22 and the second bending part 13 can effectively cooperate with the annular rubber ring 8 to achieve the sealing between the door panel 2 and the frame 1. And the first bending part 22 can isolate rainwater, and the groove formed by the second bending part 13 can effectively divert rainwater.

[0025] Specifically: As Figure 1 and Figure 2 shown, the industrial socket 3 is a PKF screw-connecting and installing inclined industrial socket 3.

[0026] In the above design, the PKF screw-connecting and installing inclined industrial socket 3 has good waterproof performance, which can ensure the waterproof requirements when wiring the distribution box.

[0027] Specifically: As Figure 1 and Figure 2 shown, horizontal hanging braces 5 are symmetrically arranged on both sides of the first plate 11, and a number of mounting holes 50 are vertically arranged on the horizontal hanging braces 5.

[0028] In actual use, the horizontal hanging angle brace 5 is installed on an external bracket or wall through an external bolt passing through the mounting hole 50.

[0029] In the above design, the installation and fixation of the distribution box can be effectively realized by setting the horizontal hanging angle brace 5.

[0030] Specifically: as Figure 2 and Figure 5 shown, a plurality of wire tying bridges 6 are provided on the first plate 11. The wire tying bridge 6 includes a fixing portion 61 fixedly connected to the first plate 11 and a bridge-shaped block 62 connected to the fixing portion 61. The bridge-shaped block 62 and the fixing portion 61 form a wire passing hole.

[0031] In actual use, the wire harnesses of each electrical module installed in the frame 1 are fixed through the wire passing holes.

[0032] In the above design, by setting the wire tying bridge 6, the wire harness in the frame 1 can be effectively fixed and limited.

[0033] For further detailed description, it should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
