Description

Technical Field

[0001] The invention relates to the technical field of cabinet waterproofing, and in particular to a cabinet waterproofing structure and a cabinet. Background Art

[0002] As an important component of electrical equipment, the cabinet plays the role of carrying and protecting the electronic devices inside the electrical equipment. The existing cabinet for electrical equipment generally includes a frame, a sealing plate assembled on the frame, and a cabinet door that can be opened and closed. Generally speaking, for cabinets in outdoor environments, there are high requirements for waterproofing and rainproofing to ensure that rainwater does not enter the cabinet and prevent rainwater from damaging the electronic devices inside the cabinet. At the same time, since the cabinet door needs to realize the opening and closing function, it is easy to form a gap between the cabinet door and the frame, causing rainwater to enter the cabinet from the gap. For this reason, in the prior art, a waterproof strip is usually set on the frame or the cabinet door. When the cabinet door is closed, the waterproof strip is squeezed and deformed, thereby closing the gap between the cabinet door and the frame to prevent rainwater from entering the cabinet. However, when the cabinet door is opened, the waterproof strip recovers its deformation. At this time, if there is water accumulation at the position of the waterproof strip, the accumulated water will drip from the waterproof strip and hit the protruding parts on the inner side of the cabinet door, such as the back panel of the display screen, and then splash onto the electronic devices inside the cabinet, causing damage to the electronic devices. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide a cabinet waterproof structure and a cabinet, which can improve the situation where accumulated water drips from the waterproof rubber strip and splashes onto the electronic devices inside the cabinet, causing damage to the electronic devices.

[0006] Technical solution 2 based on technical solution 1: the groove wall on one side of the water collecting groove is away from the inner surface of the cabinet door, and when the cabinet door is opened and within the preset angle range, it is located on the side of the outer edge of the waterproof strip away from the cabinet door on the projection surface perpendicular to the vertical direction.

[0007] Technical solution three based on technical solution two: the height of the groove wall on one side of the water receiving groove away from the inner surface of the cabinet door is configured to be higher than the splashing height of the liquid hitting the bottom of the water receiving groove.

[0008] Technical solution four based on technical solution three: two first water diversion grooves are provided on the inner side of the cabinet door, the top ends of the two first water diversion grooves are respectively connected to the two ends of the water receiving groove and extend vertically to the bottom of the cabinet door, and the opening directions of the two first water diversion grooves respectively point to the outer sides of the cabinet door corresponding to their positions.

[0009] Technical solution five based on technical solution four: the cabinet door includes a door panel and reinforcing ribs, the reinforcing ribs are fixedly installed on the door panel and are suitable for improving the structural strength of the cabinet door; the water receiving trough and the first water diversion trough are arranged on the reinforcing ribs.

[0010] Technical solution 6 based on any one of technical solutions 1 to 5: both ends of the water receiving trough extend to a position close to the side edge of the cabinet door; the cabinet body is provided with a water guide trough opening upward and extending close to the side edge of the door frame at the upper edge of its door frame, and the waterproof rubber strip is installed on a groove wall on the outer side of the water guide trough.

[0011] Technical solution seven based on technical solution six: the cabinet body is provided with a second water diversion groove at the edge positions on both sides of its door frame, the top ends of the two second water diversion grooves are respectively connected to the two ends of the water guide groove and extend vertically to the bottom of the door frame, and the opening directions of the two second water diversion grooves respectively point to the outer sides of the door frame corresponding to their positions.

[0012] Technical solution eight based on technical solution seven: the cabinet body is provided with a first flange protruding from the inner side wall of the water guide groove above the water guide groove, and the first flange extends to both sides of the cabinet body to adapt to the length of the water guide groove.

[0013] Technical solution nine based on technical solution eight: the upper edge of the cabinet door is higher than the waterproof rubber strip located at the upper edge of the door frame, and is provided with a second flange protruding inward, and the second flange extends to both sides of the cabinet door to adapt to the length of the water guide groove.

[0014] In addition, the present invention also provides technical solution ten: a cabinet, comprising a cabinet body and a cabinet door, characterized in that the cabinet body and the cabinet door adopt the cabinet waterproof structure as described in any one of technical solutions one to nine.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] Technical solution 1 provides a cabinet waterproof structure, in which a waterproof rubber strip is arranged on the side of the door frame of the cabinet body. When the cabinet door is closed, the inner surface of the cabinet door will be close to and press the waterproof rubber strip, and the waterproof rubber strip will produce a certain deformation, so that the gap between the cabinet door and the waterproof rubber strip is blocked, and the cabinet door and the cabinet body are sealed by the waterproof rubber strip, so as to prevent rainwater from the outside from entering the cabinet body; at the same time, a water receiving trough is arranged on the inner side of the cabinet door, the water receiving trough is lower than the waterproof rubber strip at the upper edge of the door frame and protrudes from the inner surface of the cabinet door, and the opening of the water receiving trough is upward. When the cabinet door is opened at a certain angle, for example, when the cabinet door is in a state where the lock on the cabinet door has just been opened, the cabinet door will be slightly opened outward at a smaller angle. In addition, the pressure of the cabinet door on the waterproof strip is removed, and a gap is formed between the waterproof strip and the cabinet door. The accumulated water on the waterproof strip will drip from the waterproof strip, and the dripping liquid will be received by the water receiving trough below, thereby preventing the liquid from dripping and hitting the protruding parts on the inner side of the cabinet door and then splashing onto the electronic devices in the cabinet; in addition, the water receiving trough extends to both sides of the cabinet door. When the water receiving trough receives a large amount of dripping liquid, the liquid can flow away from both ends of the water receiving trough, and because the water receiving trough has a certain length, the flowing liquid can avoid the protruding parts on the inner side of the cabinet door or avoid the electronic devices in the middle part of the cabinet in the left-right direction, thereby further reducing the impact of liquid splashing on the electronic devices in the cabinet.

[0017] In the second technical solution, the preset angle range in which the cabinet door is opened is limited, or the width of the water tank and its relationship with the angle range are limited. This angle range should be such that the groove wall on the side of the water tank away from the inner surface of the cabinet door is always on the inner side of the outer edge of the waterproof strip, so that when the cabinet door is opened and is within the preset angle range, the liquid dripping from the waterproof strip can be received by the water tank; at the same time, when the cabinet door is opened to a position that is not within the preset angle range, although the waterproof strip may still drip liquid at this time, because the cabinet door has been opened to a position relatively far away from the door frame, the liquid dripping from the waterproof strip can no longer hit the raised part on the inner side of the cabinet door, or even if it hits the raised part, the splashed liquid can no longer reach the electronic devices inside the cabinet.

[0018] In technical solution three, the height of the groove wall on the side of the water collecting groove away from the inner surface of the cabinet door is higher than the liquid splashing height. The liquid splashing height is related to the type of liquid and the distance between the bottom of the water collecting groove and the outer edge of the waterproof rubber strip. By limiting the groove wall height of the water collecting groove, it can be ensured that the liquid will not splash out from the water collecting groove after dripping, thereby preventing the liquid from splashing onto the electronic devices in the cabinet.

[0019] In technical solution four, two first water diversion grooves are arranged on the cabinet door, and the first water diversion grooves can guide the water in the water receiving tank to the bottom position of the cabinet, thereby reducing the impact on the electronic devices at higher positions in the cabinet.

[0020] In technical solution five, the cabinet door includes a door panel and reinforcing ribs. The reinforcing ribs can improve the overall structural strength of the cabinet door, and the thickness of the cabinet door can be thinner, thereby reducing the manufacturing cost of the cabinet door. At the same time, the reinforcing ribs are used to set the water receiving trough and the first water diversion trough, that is, the reinforcing ribs are directly processed into components with a trough structure, so there is no need to process the door panel, and the difficulty of setting the water receiving trough and the first water diversion trough is greatly reduced. At the same time, the reinforcing ribs can play a role in improving the overall structural strength of the cabinet door.

[0021] In Technical Solution 6, both ends of the water trough extend to the position near the side edge of the cabinet door. The length of the water trough is increased, so that the liquid dripping from the waterproof strip can be received as much as possible to reduce liquid splashing; and a water guide groove is also provided on the door frame. When the amount of water is large, the water guide groove can quickly drain excess water to reduce water accumulation at the waterproof strip position; at the same time, when the waterproof strip above the water trough is damaged or aged, resulting in sealing failure, the water trough can also receive liquid that penetrates into the cabinet and drain the received liquid from both ends of the water trough.

[0022] In technical solution seven, both ends of the water guide groove are connected to the second water guide groove, so that rainwater can flow along the second water guide groove to the bottom of the cabinet, preventing rainwater from overflowing from the water guide groove and entering the cabinet from the side waterproof strip.

[0023] In technical solution eight, a first flange is provided on the cabinet body, and the first flange can rebound part of the rainwater when it falls, thereby reducing the amount of water entering the water guide groove and the waterproof strip position.

[0024] In technical solution nine, a second flange is provided on the upper edge of the cabinet door. The second flange can cooperate with the first flange to form a more comprehensive shielding above the water guide groove, thereby reducing the impact on the water guide groove and the waterproof strip and increasing the service life of the waterproof strip.

[0025] Technical solution ten provides a cabinet, which includes a cabinet body and a cabinet door, and adopts the above-mentioned cabinet waterproof structure, which can improve the problem of accumulated water dripping from the waterproof strip and splashing onto the electronic devices in the cabinet when the door is opened.

[0042] Example

[0043] An embodiment of the present invention provides a cabinet, which mainly includes a cabinet body 1 and a cabinet door 2. In practical applications, corresponding electronic devices can be installed on the cabinet according to different requirements to achieve corresponding functions. For example, when the cabinet is applied to a converter, power components for rectification and inversion, as well as corresponding reactors, heat sinks, transformers, controllers and other devices can be set in the cabinet. At this time, the cabinet is used to install these electronic devices, and the electronic devices in the cabinet body 1 can be inspected and maintained by opening and closing the cabinet door 2.

[0044] Reference Figure 1The cabinet body 1 of the cabinet is roughly in the shape of a rectangular parallelepiped, and has four upright main columns, and beams are arranged between the columns, so as to form a cabinet frame with high structural strength and stability. Closing plates are arranged on the left, right, rear, bottom and top sides of the frame, and the cabinet body 1 is closed by the closing plates, leaving an opening at the front side of the cabinet body 1. The cabinet door 2 is installed on the cabinet body 1 through a hinge, and can be opened or closed by rotating the front opening of the cabinet body 1. Among them, the front opening of the cabinet body 1 forms a door frame of the cabinet body 1 around the cabinet body 1, and the cabinet door 2 can cooperate with the door frame to open or close the cabinet body 1.

[0045] The cabinet provided in this embodiment adopts the cabinet waterproof structure proposed in the present invention, and the cabinet waterproof structure is described in detail below.

[0046] Reference Figure 1 , Figure 2 and Figure 3 A waterproof rubber strip 3 is provided around the door frame of the cabinet 1, and the inner surface of the cabinet door 2 is suitable for being close to and pressing the waterproof rubber strip 3 to block the gap between the cabinet door 2 and the cabinet 1 when it is closed. The waterproof rubber strip 3 can be an annular rubber ring, which can be fixed around the door and play a waterproof role for the opening of the cabinet 1. Since the door frame is rectangular, the waterproof rubber strip 3 also has four sides, each of which is parallel to the edge of the door frame where it is located.

[0047] The structure of the waterproof rubber strip 3 can be referred to Figure 4 , Figure 5 and Figure 6 The waterproof rubber strip 3 has a fixing portion 31 for fixing on the door frame. The fixing portion 31 can be fixedly connected to the door frame of the cabinet body 1 by various methods such as pasting, clamping, and pressing. At the same time, the front side of the waterproof rubber strip 3 is a deformable deformation portion 32. When the cabinet door 2 is closed, the inner surface of the cabinet door 2 will be tightly attached to the deformation portion 32 on the front side of the waterproof rubber strip 3, and force the deformation portion 32 to deform, so that the waterproof rubber strip 3 is tightly attached to the inner surface of the cabinet door 2, thereby blocking the gap between the cabinet door 2 and the cabinet body 1, and preventing rainwater, dust, etc. from entering the cabinet. Among them, the deformation portion 32 can be an internal hollow structure. The internal hollowness makes the waterproof rubber strip 3 have better deformation ability. At the same time, because the waterproof rubber strip 3 is made of elastic materials such as rubber, it can automatically restore its deformation when the cabinet door 2 is opened. In this embodiment, a convex strip 33 extending parallel to the edge of the door frame where the deformable portion 32 of the waterproof rubber strip 3 is further provided at the front side thereof, the convex strip 33 protruding from the surface of the deformable portion 32 and provided on both the inner side and the outer side of the waterproof rubber strip 3. When the cabinet door 2 is closed, the edge of the convex strip 33 and the front end of the deformable portion 32 will be closely attached to the inner surface of the cabinet door 2, and at this time, the convex strips 33 on the upper and lower sides cooperate with the front end of the deformable portion 32 to achieve a triple-barrier waterproof effect.

[0048] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8 A water collecting groove 4 protruding from the inner surface of the cabinet door 2 is provided on the inner side of the cabinet door 2 near its upper edge, and the water collecting groove 4 is lower in height than the waterproof rubber strip 3 located on the upper edge of the door frame of the cabinet body 1; the water collecting groove 4 opens upward and extends to both sides of the cabinet door 2, and is suitable for receiving liquid dripping from the waterproof rubber strip 3 located above it when the cabinet door 2 is opened and within a preset angle range.

[0049] Specifically, refer to Figure 7 It is easy to see that for the cabinet door 2 of the electrical cabinet, there must be components such as a display installed thereon, and these components will protrude from the inner surface of the cabinet door 2. When the cabinet door 2 is opened, the accumulated water on the waterproof rubber strip 3 will drip onto these protruding components and then splash onto the electronic devices inside the cabinet, thereby causing damage to the electronic devices.

[0050] To this end, in this embodiment, a water receiving groove 4 is provided at the upper edge of the cabinet door 2, and the water receiving groove 4 protrudes from the inner surface of the cabinet door 2, and its opening extends upward and to the left and right sides of the cabinet door 2. The water receiving groove 4 has a certain width, and a groove wall is provided on the side away from the inner surface of the cabinet door 2, and the groove wall is a first groove wall 41 here; and the water receiving groove 4 is located above the protruding part on the inner side of the cabinet door 2, and there is no shielding between the waterproof rubber strip 3. Therefore, when the cabinet door 2 is just opened, the waterproof rubber strip 3 restores its deformation, and the accumulated water drips from the waterproof rubber strip 3 into the water receiving groove 4, and the first groove wall 41 of the water receiving groove 4 will block the splashing of the liquid, thereby improving the situation where the liquid splashes onto the electronic devices inside the cabinet body 1.

[0051] Generally speaking, when the cabinet door 2 is closed, the inner surface of the cabinet door 2 will be in close contact with and compress the waterproof adhesive strip 3, and the waterproof adhesive strip 3 will produce a certain deformation, so that the gap between the cabinet door 2 and the waterproof adhesive strip 3 is blocked, and the cabinet door 2 and the cabinet body 1 are sealed by the waterproof adhesive strip 3, thereby preventing rainwater from the outside from entering the cabinet body 1; at the same time, a water receiving trough 4 is arranged on the inner side of the cabinet door 2, and the water receiving trough 4 is lower than the waterproof adhesive strip 3 at the upper edge of the door frame and protrudes from the inner surface of the cabinet door 2, and the opening of the water receiving trough 4 faces upward. When the cabinet door 2 is opened at a certain angle, for example, when the cabinet door 2 is in a state where the lock on the cabinet door 2 has just been opened, the cabinet door 2 will be slightly opened outward at a smaller angle, and the pressure of the cabinet door 2 on the waterproof adhesive strip 3 is removed. , a gap is formed between the waterproof rubber strip 3 and the cabinet door 2, and the accumulated water on the waterproof rubber strip 3 will drip from the waterproof rubber strip 3, and the dripping liquid will be received by the water receiving groove 4 below, thereby preventing the liquid from dripping and hitting the protruding parts on the inner side of the cabinet door 2 and then splashing onto the electronic devices in the cabinet body 1; and the water receiving groove 4 extends to both sides of the cabinet door 2. When the water receiving groove 4 receives a large amount of dripping liquid, the liquid can flow away from both ends of the water receiving groove 4, and because the water receiving groove 4 has a certain length, the flowing liquid can avoid the protruding parts on the inner side of the cabinet door 2 or avoid the electronic devices in the middle part of the cabinet body 1 in the left-right direction, further reducing the impact of liquid splashing on the electronic devices in the cabinet body 1.

[0052] The side groove wall of the water receiving groove 4 away from the inner surface of the cabinet door 2 is located on the side of the outer edge of the waterproof rubber strip 3 away from the cabinet door 2 on the projection plane perpendicular to the vertical direction when the cabinet door 2 is opened and within the preset angle range. The height of the side groove wall of the water receiving groove 4 away from the inner surface of the cabinet door 2 is configured to be higher than the splash height of the liquid that hits the bottom of the water receiving groove 4.

[0053] Specifically, the width of the water receiving groove 4 needs to be adapted to a preset angle range, which is slightly different according to the size of the cabinet door 2, but is roughly within the range of 1° to 8°. When the cabinet door 2 is opened and within the range, the pressure of the inner surface of the cabinet door 2 on the waterproof rubber strip 3 is removed, and the accumulated water of the waterproof rubber strip 3 will drip. At this time, since the first groove wall 41 of the water receiving groove 4 is still located inside the outer edge of the waterproof rubber strip 3, the dripping liquid will still fall into the water receiving groove 4, thereby preventing the liquid from splashing to the position of the cabinet body 1. As an embodiment, the width of the water receiving groove 4 can be made greater than the protrusion of the protruding part of the inner surface of the cabinet door 2, so as to ensure that the accumulated water will definitely drip into the water receiving groove 4. However, as a better choice, the water receiving groove 4 does not need to be set too wide, because after the cabinet door 2 is opened, even if the accumulated water drips on the protruding part on the inner side of the cabinet door 2, the kinetic energy of the splashed liquid is not necessarily sufficient to contact the electronic devices inside the cabinet body 1, and the harm caused by the dripping and splashing of the accumulated water is greatly reduced.

[0054] By limiting the preset angle range in which the cabinet door 2 is opened, or in other words, limiting the width of the water tank 4 and its relationship with the angle range, this angle range should be such that the groove wall on one side of the water tank 4 away from the inner surface of the cabinet door 2 is always on the inner side of the outer edge of the waterproof strip 3, so that when the cabinet door 2 is opened and is within the preset angle range, the liquid dripping from the waterproof strip 3 can be received by the water tank 4; at the same time, when the cabinet door 2 is opened to a point where it is not within the preset angle range, although the waterproof strip 3 may still drip liquid at this time, since the cabinet door 2 has been opened to a position relatively far away from the door frame, the liquid dripping from the waterproof strip 3 can no longer hit the protruding part on the inner side of the cabinet door 2, or even if it hits the protruding part, the splashed liquid can no longer reach the electronic devices inside the cabinet body 1.

[0055] Furthermore, the height of the first groove wall 41 of the water receiving groove 4 is also adapted to the distance between the groove bottom of the water receiving groove 4 and the waterproof rubber strip 3. The density of rainwater is known, and the kinetic energy of rainwater dripping can be known according to the distance from the groove bottom of the water receiving groove 4 to the edge of the dripping liquid of the waterproof rubber strip 3, and the height and angle of rainwater splashing can be determined according to the kinetic energy. According to these conditions, the height of the first groove wall 41 can be designed so that the height of the first groove wall 41 can meet the requirement of avoiding water splashing to the outside of the water receiving groove 4.

[0056] In addition, two first water diversion grooves 5 are provided on the inner side of the cabinet door 2, the top ends of the two first water diversion grooves 5 are respectively connected to the two ends of the water receiving groove 4 and extend vertically to the bottom of the cabinet door 2, and the opening directions of the two first water diversion grooves 5 are respectively directed to the outer sides of the cabinet door 2 corresponding to their positions.

[0057] Specifically, refer to Figure 3 , Figure 7 and Figure 8 There are two first water diversion grooves 5, both extending in the vertical direction and opening toward the outside of the cabinet, one of the first water diversion grooves 5 is located on the left side of the cabinet door 2, and its upper end is connected to the left end of the water receiving groove 4, and the other first water diversion groove 5 is located on the right side of the cabinet door 2, and its upper end is connected to the right end of the water receiving groove 4. The lower end of the first water diversion groove 5 extends to the bottom of the cabinet door 2. When the water receiving groove 4 receives the accumulated water, the accumulated water will flow from the first water diversion groove 5 to the bottom of the cabinet, reducing the impact on the electronic components at a higher position in the cabinet.

[0058] At the same time, when the waterproof rubber strip 3 is damaged, water may seep in even if the door is not opened. At this time, the water receiving tank 4 can receive the infiltrated liquid and discharge the received liquid from both ends of the water receiving tank 4 to the first water diversion tank 5. Among them, a drainage channel can be set at the bottom of the cabinet 1, such as a one-way valve, or simply a drain port to drain excess water from the drainage channel. In addition, a dehumidifier can be set in the cabinet. Since the electronic devices in the cabinet will emit a lot of heat when running, this heat will evaporate the accumulated water and then be discharged through the dehumidifier.

[0059] In this embodiment, refer to Figure 6 , Figure 7 and Figure 8 The cabinet door 2 includes a door panel 6 and a reinforcing rib 7, wherein the reinforcing rib 7 is fixedly mounted on the door panel 6 and is suitable for improving the structural strength of the cabinet door 2; the water receiving groove 4 and the first water diversion groove 5 are arranged on the reinforcing rib 7. The reinforcing rib 7 can improve the overall structural strength of the cabinet door 2, and the thickness of the cabinet door 2 can be thinner, thereby reducing the manufacturing cost of the cabinet door 2; at the same time, the reinforcing rib 7 is used to set the water receiving groove 4 and the first water diversion groove 5, that is, the reinforcing rib 7 is directly processed into a component with a groove structure, so that there is no need to process the door panel 6, and the difficulty of setting the water receiving groove 4 and the first water diversion groove 5 is greatly reduced. At the same time, the reinforcing rib 7 can also play a role in improving the overall structural strength of the cabinet door 2. The reinforcing rib 7 is a metal profile, which generally has a groove-shaped structure, but generally speaking, the opening of the groove-shaped structure on the reinforcing rib 7 will face the cabinet door 2 or the cabinet body 1, rather than the opening outward. The present invention creatively utilizes the original reinforcing ribs 7 on the cabinet, and turns the opening of the groove on the reinforcing ribs 7 to face the outside of the cabinet, thereby playing the role of receiving and guiding water.

[0060] In addition, refer to Figure 3 and Figure 6 The two ends of the water receiving groove 4 extend to the position of the cabinet door 2 near the side edge; the cabinet body 1 is provided with a water guide groove 8 opening upward and extending to the side edge of the door frame at the upper edge of its door frame, and the waterproof rubber strip 3 is installed on the outer side groove wall of the water guide groove 8.

[0061] Among them, both ends of the water receiving groove 4 extend to the position near the side edge of the cabinet door 2. The length of the water receiving groove 4 is increased, and the liquid dripping from the waterproof rubber strip 3 can be received as much as possible to reduce the splashing of the liquid. The groove wall of the water guide groove 8 away from the cabinet body 1 is the second groove wall 81, and the fixing part 31 of the waterproof rubber strip 3 is inserted on the second groove wall 81 for fixation. When the amount of water is large, the water guide groove 8 can quickly drain away the excess water and reduce the accumulation of water at the position of the waterproof rubber strip 3. After the accumulation of water at the position of the waterproof rubber strip 3 is reduced, the rainwater dripping when the cabinet door 2 is opened will be less, and the splashing situation will also be improved. The water receiving groove 4 can better receive the dripping rainwater.

[0062] Reference Figure 3 The cabinet 1 is provided with a second water diversion groove 9 at the edge positions on both sides of the door frame, the tops of the two second water diversion grooves 9 are respectively connected to the two ends of the water guide groove 8 and extend vertically to the bottom of the door frame, and the opening directions of the two second water diversion grooves 9 are respectively directed to the outer sides of the side portions of the door frame corresponding to their positions. The structure and function of the second water diversion groove 9 are similar to those of the first water diversion groove 5, except that it is connected to the water guide groove 8. The two ends of the water guide groove 8 are connected to the second water diversion groove 9, so that rainwater can flow to the bottom of the cabinet 1 along the second water diversion groove 9, and prevent rainwater from overflowing from the water guide groove 8 and entering the cabinet 1 from the position of the waterproof rubber strip 3 on the side.

[0063] Reference Figure 3 and Figure 6 The cabinet body 1 is provided with a first flange 10 protruding from a groove wall on the inner side of the water guide groove 8 above the water guide groove 8, and the first flange 10 extends to both sides of the cabinet body 1 to match the length of the water guide groove 8. At the same time, the upper edge of the cabinet door 2 is higher than the waterproof rubber strip 3 located at the upper edge of the door frame, and is provided with a second flange 11 protruding inwardly, and the second flange 11 extends to both sides of the cabinet door 2 to match the length of the water guide groove 8.

[0064] Specifically, refer to Figure 6 In this embodiment, the water inlet position of the cabinet door 2 is above the first flange 10, which is formed by the top plate of the cabinet body 1 extending forward for a distance, and can block rainwater so that rainwater will not directly pour into the water guide groove 8. Below the first flange 10, a second flange 11 is also provided on the door panel 6 of the cabinet door 2, and the second flange 11 can be formed by fixing a metal profile on the inner side of the door panel 6. The second flange 11 has an overlapping portion with the first flange 10 and the water gutter 8 on a projection surface perpendicular to the vertical direction, and the second flange 11 is located between the first flange 10 and the water gutter 8. After being blocked by the first flange 10, rainwater will fall to the position of the second flange 11, and then be blocked by the second flange 11, and then fall into the position of the water gutter 8, thereby reducing the kinetic energy of rainwater and preventing rainwater from directly impacting the water gutter 8 and the waterproof strip 3. The water gutter 8 can effectively drain rainwater from both sides, and the waterproof strip 3 is not easily damaged by impact.

[0065] An embodiment of the present invention provides a cabinet, which includes a cabinet body 1 and a cabinet door 2. Electronic devices can be installed inside the cabinet body 1 to realize corresponding electrical functions. At the same time, the cabinet adopts a cabinet waterproof structure proposed by the present invention. The cabinet waterproof structure can improve the situation where accumulated water drips from the waterproof rubber strip 3 and splashes onto the electronic devices inside the cabinet, causing damage to the electronic devices.

[0066] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
