Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, and in particular to a structural waterproof double-opening door. Background Art

[0002] Outdoor boxes and cabinets are in direct contact with the outside world and usually need to meet the requirements of rain and dustproof. Generally, electrical equipment is installed and stored inside outdoor boxes and cabinets. In case of severe rain, snow and strong wind, the external structure should provide sufficient protection for the internal equipment to ensure the performance of the fragile internal components and prevent safety accidents.

[0003] In the prior art, common waterproofing measures for electrical equipment mainly rely on designs such as sealing strips and water retaining plates. However, these designs are prone to unsatisfactory sealing effects during long-term use, causing moisture to penetrate into the interior of the equipment, affecting its normal operation. For example, in the traditional double-door structure, there will inevitably be problems such as gaps between the door panels and the door frames. The prior art mainly achieves sealing through sealing strips between the door panels and the door frames, but this method will significantly reduce the sealing effect after long-term use, and rainwater can easily enter the interior of the car through the gaps, affecting the waterproof performance of the equipment.

[0060] Combination Figures 1 to 9The present invention provides a structural waterproof double door, comprising a door frame 1, a first door panel 2, a second door panel 3, a hinge 4 and a sealing assembly 5; the door frame 1 is connected to the first door panel 2 through the hinge 4, the door frame 1 is connected to the second door panel 3 through the hinge 4, the sealing assembly 5 is arranged on the inner side of the door frame 1, and the sealing assembly 5 is arranged at the joint between the first door panel 2 and the second door panel 3; the door frame 1 comprises an upper frame 11, a side frame 12 and a lower frame 13, the upper frame 11 and the side frame 12 are formed with a first guide groove 1a, the first door panel 2 and the second door panel 3 are connected to each other through the hinge 4, the sealing assembly 5 is arranged on the inner side of the door frame 1, and the sealing assembly 5 is arranged at the joint between the first door panel 2 and the second door panel 3 The first guide groove 1a is arranged inside, the lower frame 13 is formed with a drainage groove 1b, and the first guide groove 1a is connected with the drainage groove 1b; the upper frame 11 is provided with a first water baffle 111, the first water baffle 111 is located at the outer bottom of the first guide groove 1a, the first water baffle 111 is abutted with the first door panel 2 and the second door panel 3, the first door panel 2 is formed with a second guide groove 2a on the side close to the second door panel 3, the second guide groove 2a is connected with the drainage groove 1b, and the second guide groove 2a guides the rainwater of the first water baffle 111 to the drainage groove 1b. In the structure of the outdoor double door, it is inevitable that there will be a structural gap between the door frame 1 and the door panel, and the traditional sealing and water-blocking method has a poor waterproof effect in long-term use. In the embodiment of the present invention, by designing the structure of the door frame 1 and the first door panel 2 and the second door panel 3, the rainwater entering the gap can be discharged along the four sides of the door frame 1, and the rainwater can be effectively prevented from entering the interior of the box. Specifically, a first guide groove 1a is formed on the upper frame 11 and the side frame 12, and a drainage groove 1b is formed on the lower frame 13. The overall structure of the door frame 1 adopts an embedded design, that is, a curling edge is provided on the periphery of the door frame 1, wherein the curling edge is bonded, welded or integrally formed with the cabinet body, and this embodiment does not limit it. The first guide groove 1a and the drainage groove 1b are arranged on the inner side of the door frame 1. After rainwater enters the periphery of the door frame 1 along the gap, it directly enters the first guide groove 1a and the drainage groove 1b. The first guide groove 1a guides the rainwater to the drainage groove 1b, and the rainwater is discharged through the drainage groove 1b at the bottom of the door frame 1 to prevent the rainwater from entering the cabinet body. In the same way, a second guide groove 2a is formed on the first door panel 2, and at the position where the first door panel 2 and the second door panel 3 are connected, there is a first water retaining plate 111 at the upper frame 11, which can prevent rainwater from entering the box body at the top of the first door panel 2 and the second door panel 3, and can also guide the rainwater to the second guide groove 2a. The second guide groove 2a can guide the rainwater in the gap between the first door panel 2 and the second door panel 3 to the drainage groove 1b, thereby draining all the rainwater that inevitably enters the double door. In addition, a sealing component 5 is provided on the inner side of the door frame 1 and the joint of the first door panel 2 and the second door panel 3 to prevent the rainwater in the first guide groove 1a, the drainage groove 1b and the second guide groove 2a from entering the box body in a flowing or heavy rain environment.

[0061] It should be noted that the processing and forming method of the first guide groove 1a and the drainage groove 1b on the door frame 1 is not limited here, nor is the processing and forming method of the second guide groove 2a on the first door panel 2. It can be formed by welding multiple metal structures. Preferably, the upper frame 11, the side frame 12 and the lower frame 13 are respectively processed and formed as one piece, and then the overall structure of the door frame 1 is formed by welding. This is conducive to the integrity of the first guide groove 1a and the drainage groove 1b, and avoids the first guide groove 1a and the drainage groove 1b formed by welding from rusting or damage in the case of long-term contact with rainwater. The second guide groove 2a is also formed in the same way, and is formed by being processed and formed as one piece with the first door panel 2. The specific shape of the first water baffle 111 is not limited here. It can be a straight plate arranged on the outer side of the bottom of the upper frame 11, and is arranged parallel to the first door panel 2 and the second door panel 3. When the double doors are closed, the first door panel 2 and the second door panel 3 abut against the first water baffle 111. In a preferred case, the first water baffle 111 is arranged into a right-angle U-shaped structure, with a straight plate parallel to the first door panel 2 and the second door panel 3, and side panels are provided on both sides of the straight plate. The side panels on both sides can prevent rainwater from flowing to both sides. Through such an arrangement, the first water baffle 111 forms a small groove structure for diverting water downward, and guides rainwater in the top gap of the first door panel 2 and the second door panel 3 to the second guide groove 2a.

[0062] Combination Figures 1 to 11In a preferred case, the first door panel 2 includes a first outer door panel 21 and a first inner door panel 22, a second water baffle 221 is formed on the top of the first outer door panel 21, the second water baffle 221 is inclined toward the first guide groove 1a, one end of the second water baffle 221 is arranged in the first guide groove 1a, and the first inner door panel 22 is arranged on the inner side of the first guide groove 1a; the second door panel 3 includes a second outer door panel 31 and a second inner door panel 32, a third water baffle 311 is formed on the top of the second outer door panel 31, the third water baffle 311 is inclined toward the first guide groove 1a, one end of the third water baffle 311 is arranged in the first guide groove 1a, and the second inner door panel 32 is arranged on the inner side of the first guide groove 1a. By such arrangement, the second water baffle 221 and the third water baffle 311 can separate the rainwater entering from the gap of the upper frame 11 from the inner side of the first door panel 2 and the second door panel 3. Meanwhile, the second water baffle 221 and the third water baffle 311 are inclined toward the first guide groove 1a and one end is arranged in the first guide groove 1a, which is more conducive to the rainwater on the surface of the second water baffle 221 and the third water baffle 311 flowing into the first guide groove 1a. In addition, the first inner door panel 22 and the second inner door panel 32 are arranged in the inner side of the first guide groove 1a, that is, the top surface and both sides of the first inner door panel 22 and the second inner door panel 32 are provided with the first guide groove 1a, and the bottom is provided with a drainage groove 1b. By such arrangement, combined with the arrangement of the sealing assembly 5, it is possible to effectively prevent rainwater from entering the first inner door panel 22 and the second inner door panel 32, thereby ensuring the overall waterproof performance of the double-opening door. Specifically, after the double door is set on the box body, the upper door frame 1 is usually set horizontally, and the first door panel 2 and the second door panel 3 are opened to both sides. At this time, the first guide groove 1a formed on the upper frame 11 is located above the first inner door panel 22 and the second inner door panel 32, and the second water baffle 221 is formed on the top of the first outer door panel 21, and the third water baffle 311 is formed on the top of the second outer door panel 31. The second water baffle 221 and the third water baffle 311 are arranged in the direction where the first inner door panel 22 and the second inner door panel 32 are located, and extend to the space where the first guide groove 1a is located, so that rainwater in the gap between the upper frame 11 and the first door panel 2 and the second door panel 3 can be guided to the first guide groove 1a. The connection relationship between the second water baffle 221 and the first outer door panel 21 is not limited here, nor is the connection relationship between the third water baffle 311 and the second outer door panel 31. It can be welded, and preferably a bending molding method is adopted to improve the integrity of the first outer door panel 21 and the second outer door panel 31.In a preferred case, the second water guide groove is arranged between the first inner door panel 22 and the second inner door panel 32. Specifically, the second water guide groove is formed inwardly on the first outer door panel 21 by bending inward, and the side wall of the second water guide groove is fitted with one side of the first inner door panel 22. Preferably, the outer contour depth of the second water guide groove is the same as the thickness of the first inner door panel 22 and the second inner door panel 32. Through such an arrangement, the second guide groove 2a and the second inner door panel 32 are on the same plane as the second inner door panel 32, thereby ensuring the drainage effect while saving the overall structural space, and can also effectively prevent rainwater from entering the box along the sides where the first inner door panel 22 and the second inner door panel 32 are connected.

[0063] It should be noted that the connection relationship between the first inner door panel 22 and the first outer door panel 21 is not limited here, and can be welded or screwed, or integrally formed. The thickness and internal structure of the first inner door panel 22 are also not limited. Specifically, the four sides of the first inner door panel 22 are all located on the inner side of the four sides of the first outer door panel 21, that is, the front area of ​​the first inner door panel 22 is smaller than that of the first outer door panel 21. Through such a setting, when the first door panel 2 is closed, the first inner door panel 22 can be set on the inner side of the first guide groove 1a and the drainage groove 1b in the circumferential direction, thereby achieving rainwater discharge from all sides of the first inner door panel 22 to prevent rainwater from entering the box. The structures of the second inner door panel 32 and the second outer door panel 31 are similar to those of the first inner door panel 22 and the first outer door panel 21, and will not be repeated here.

[0064] In a preferred case, a fourth water baffle 221 is provided on the top of the first inner door panel 22, and the fourth water baffle 221 includes a first surface and a second surface perpendicular to each other, the top of the first surface is fitted with the first water baffle 111, the bottom of the first surface is located above the second guide groove 2a, and the second surface is fixedly connected to the outer side of the side wall of the second guide groove 2a. Specifically, the fourth water baffle 221 is set to a first surface and a second surface perpendicular to each other, and when the first door panel 2 and the second door panel 3 are closed, the first surface overlaps the first water baffle 111, and the second surface and the second guide groove 2a are fixed close to the side wall of the first inner door panel 22, which can prevent rainwater from entering the first inner door panel 22 along one side of the first water baffle 111. At the same time, in order to ensure the opening and closing action of the first door panel 2 and the second door panel 3, a certain gap will be reserved at the top of the first water baffle 111 and the second guide groove 2a, and the bottom of the first surface of the fourth water baffle 221 is set above the second guide groove 2a, which can effectively prevent rainwater from entering the box along the gap between the first water baffle 111 and the second guide groove 2a. It should be noted that the bottom of the first surface of the fourth water baffle 221 is at least parallel to the top of the second guide groove 2a to ensure the water-proof effect. Optionally, the bottom of the first surface of the fourth water baffle 221 can also extend into the second guide groove 2a to further ensure that the rainwater entering the gap is directed to the second guide groove 2a. The molding method of the fourth water baffle 221 is not limited here, and bending molding is preferably adopted. The specific fixing method of the second surface of the fourth water baffle 221 is also not limited. One side of the second surface can be directly welded to the inner side of the first outer door panel 21, and the other side can be welded to the top of the first inner door panel 22 to achieve a water-proof effect, or the side wall of the second water guide groove close to the second inner door panel 32 is extended and welded to the second surface of the fourth water baffle 221. Through such a setting, the first door panel 2 and the second door panel 3 can avoid the upper door frame 1 and the first water baffle 111 during the opening and closing process, and the rainwater in the gap can be guided to the second guide groove 2a to achieve a water-proof effect.

[0065] Combination Figures 10 to 14 In a preferred case, a first guide plate 222 is further provided at the top of the first inner door panel 22, one end of the first guide plate 222 abuts against the first outer door panel 21, and the other end of the first guide plate 222 is flush with the inner wall of the second guide groove 2a near the first inner door panel 22. Specifically, in extreme cases, such as during the opening and closing of the double doors on rainy days or in a rainstorm environment, rainwater may enter the top side of the first inner door panel 22. At this time, the first guide plate 222 blocks rainwater from entering the box along the top side of the first inner door panel 22, and at the same time guides rainwater to the second guide groove 2a, thereby improving the waterproof performance of the overall structure. The specific structure of the first guide plate 222 is not limited here, and it can play the role of blocking rainwater and guiding rainwater to the second guide groove 2a on the side of the top of the second inner door panel 32 near the fourth water retaining plate 221.

[0066] In a preferred case, a fifth water baffle 312 is provided on the side of the second outer door panel 31 close to the first door panel 2, the fifth water baffle 312 is provided in the second guide groove 2a, and the fifth water baffle 312 abuts against the first surface of the fourth water baffle 221. Specifically, when the upper frame 11 is in a horizontal setting state, the fifth water baffle 312 is vertically provided between the first door panel 2 and the second door panel 3, and when the double doors are closed, the top of the fifth water baffle 312 abuts against the first surface of the fourth water baffle 221. Through such a setting, the gap between the first door panel 2 and the second door panel 3 extends to the gap between the fifth water baffle 312 and the side wall of the second guide groove 2a close to the first door panel 2, and rainwater enters the gap where the first outer door panel 21 and the second outer door panel 31 meet through the gap, and the fifth water baffle 312 blocks the rainwater from entering the box body in the direction of the second inner door panel 32, and at the same time, the rainwater is introduced into the second guide groove 2a.
