Description

Technical Field

[0001] The present invention relates to the technical field of equipment boxes, and more specifically, to an electrical equipment box for solar energy. Background Art

[0002] At present, electrical equipment is widely used, both indoors and outdoors. The outdoor environment is relatively harsh, with media such as liquids, gases, and dust. Some of these media have characteristics such as corrosion, viscosity, crystallization, pollution, heat dissipation prevention, and conductivity, and some even have flammable and explosive characteristics. These harmful and dangerous media can cause damage to outdoor electrical equipment and components. Therefore, electrical equipment used outdoors generally comes with corresponding protective boxes to protect the electrical equipment from harmful media and prevent the electrical equipment from being accidentally touched.

[0003] Chinese Patent with the authorization publication number CN109413909A discloses an electrical equipment box, which designs the electrical equipment box door to be pushed and pulled towards both sides, and realizes the pushing and pulling of the door body through a rod assembly with a rotating rod and a knob, and the operation is very convenient.

[0004] Although this electrical equipment box realizes the pushing and pulling of the door body and the operation is very convenient, in the actual use process, the existing electrical equipment box usually uses hinges to connect the door body to the cabinet. Such a design, although meeting the daily use requirements to a certain extent, also exposes some deficiencies in actual operation. Especially when it is necessary to open or close a double-door body, users often need to use both hands to complete this process smoothly: first, use one hand to open one door, and then use the other hand to pull the other door; when closing, it is necessary to carefully ensure that the two doors can be accurately connected one after the other and finally achieve a tight fit. This traditional opening and closing method not only increases the operation difficulty for users, but in some special environments (such as narrow space, insufficient light, etc.), it may even cause delays in equipment maintenance and inspection work due to the inability to be normally opened, thus affecting the stable operation and efficiency of the entire system. Summary of the Invention

[0013] Further, clamping grooves are opened on the front end face and the rear end face of the fixing plate, and clamping blocks are fixedly installed on both inner walls of the U-shaped plate.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 9, an electrical equipment box for solar energy, including a cabinet body 1. Support legs 2 are fixedly installed at the four corners of the lower end face of the cabinet body 1. There are two groups of cabinet doors 3 arranged on the front side of the cabinet body 1. Slide rails 5 are provided on the rear end face of the cabinet doors 3. A slider 4 is fixedly installed on the front end face of the cabinet body 1, and the slider 4 is slidably connected with the slide rail 5. A closing mechanism is arranged inside the cabinet body 1, a sealing mechanism is arranged inside the closing mechanism, and a fixing mechanism one and a fixing mechanism two are arranged between the two groups of cabinet doors 3. The closing mechanism includes an inner cavity 6 opened inside the cabinet body 1. A threaded rod 7 is rotatably connected inside the inner cavity 6. A handle 8 is arranged on the upper side of the cabinet body 1. The upper end of the threaded rod 7 extends to the upper side of the cabinet body 1 and is fixedly connected with the handle 8. Threaded sleeves 9 are helically driven and connected on both sides of the outer surface of the threaded rod 7. Connecting rods 12 are rotatably connected on both sides of the outer surface of the two groups of threaded sleeves 9. Transmission rods 10 are slidably connected on both sides inside the inner cavity 6. Clamping rods 13 are fixedly installed at both ends of the transmission rod 10. The other ends of the two groups of clamping rods 13 are respectively fixedly connected with the corresponding cabinet doors 3. The thread groove on the outer surface of the threaded rod 7 is a double-thread groove. A top block 11 is fixedly installed on one side of the transmission rod 10, and the two groups of connecting rods 12 on the same side are rotatably connected with the corresponding top block 11.

[0034] When it is necessary to close the cabinet door 3, by turning the handle 8 on the threaded rod 7, the threaded rod 7 rotates. The thread groove on the outer surface of the threaded rod 7 is a double-thread groove. Therefore, the two groups of threaded sleeves 9 helically driven and connected on both sides of the outer surface of the threaded rod 7 will move towards each other. Each threaded sleeve 9 will drive the two groups of connecting rods 12 to move. The two groups of connecting rods 12 on the same side are rotatably connected with the top block 11 on the transmission rod 10. Therefore, the two groups of transmission rods 10 will be driven to move towards each other. The clamping rods 13 at the ends of the transmission rods 10 will move towards each other synchronously. The two groups of clamping rods 13 are respectively fixedly connected with the two groups of cabinet doors 3. Therefore, the two groups of cabinet doors 3 will move towards each other, thus closing the cabinet doors 3 and sealing the cabinet body 1.

[0035] The sealing mechanism includes a limiting shell 15 fixedly installed on the front side of the inner wall of the cabinet body 1. A sealing airbag 16 is arranged inside the limiting shell 15. A transmission airbag 14 is fixedly installed between the two groups of clamping rods 13. A first connecting pipe 17 is communicated between the transmission airbag 14 and the sealing airbag 16.

[0036] Secondly, when the two groups of clamping rods 13 move towards each other, they will squeeze the transmission airbag 14 fixedly installed between the two groups of clamping rods 13, so that the gas inside the transmission airbag 14 enters the inside of the sealing airbag 16 through the first connecting pipe 17. The sealing airbag 16 will expand and, under the limiting action of the limiting shell 15, expand towards the cabinet door 3, thus closely adhering to the cabinet door 3, increasing the tightness between the cabinet body 1 and the cabinet door 3, and preventing moisture and dust from entering the inside of the cabinet body 1 through the gaps and affecting the normal operation of the equipment inside the cabinet body 1.

[0037] Existing electrical equipment boxes usually use hinges to connect the door body to the cabinet body 1. Although such a design meets the needs of daily use to a certain extent, it also exposes some shortcomings in actual operation. Especially when it is necessary to open or close the double-door body, the user often needs to use both hands at the same time to successfully complete this process: first use one hand to open one door, and then use the other hand to pull the other door; and when closing, it is necessary to carefully ensure that the two doors can be accurately connected one after the other, and finally achieve a tight engagement. This traditional opening and closing method not only increases the user's operating difficulty, but also in some special environments (such as small space, insufficient light, etc.), it may even cause delays in equipment maintenance and inspection work due to failure to open normally, thereby affecting the stable operation and efficiency of the entire system. Therefore, this solution sets a closing mechanism. Compared with the traditional outward push-opening method, the horizontal sliding design saves more space, which is particularly suitable for narrow environments or environments with high requirements for space utilization. This structure also reduces the wear caused by frequent opening and closing, and extends the service life of the cabinet door 3 and its components.

[0038] The fixing mechanism 1 includes a sleeve 19 fixedly mounted on the upper end surface of the cabinet door 3, a connecting pipe 2 18 is provided between the sleeve 19 and the transmission airbag 14, a piston plate 20 is slidably connected inside the sleeve 19, a rack 21 is provided on the upper side of the sleeve 19, the rack 21 is fixedly connected to the piston plate 20, a support member 22 is provided on one side of the sleeve 19, the support member 22 is fixedly connected to the cabinet door 3, the upper end of the support member 22 is rotatably connected to a rotating shaft 23, a gear 24 is fixedly installed on the outer surface of the rotating shaft 23, the gear 24 and the rack 21 are connected. Meshing, sleeve 19, piston plate 20, connecting pipe 18, rack 21, support member 22, rotating shaft 23 and gear 24 are respectively provided with two groups corresponding to the two groups of cabinet doors 3, and are symmetrically arranged, the front sides of the two groups of support members 22 are respectively provided with fixed plates 25 and U-shaped plates 27, the two groups of rotating shafts 23 are extended to the front sides of the support members 22, and are respectively fixedly connected to the fixed plates 25 and the U-shaped plates 27, the front end face and the rear end face of the fixed plate 25 are provided with card grooves 26, and the inner walls on both sides of the U-shaped plate 27 are fixedly installed with card blocks 28.

[0039] The opposite movement of the two groups of cabinet doors 3 will cause the fixing mechanism of each group to be displaced. At the same time, the gas inside the transmission airbag 14 will enter the interior of the sleeve 19 through the connecting pipe 18, so that the piston plate 20 inside the sleeve 19 will be lifted upward and the rack 21 will rise. The rack 21 is meshed with the gear 24 on the rotating shaft 23, so the rotating shaft 23 will rotate. The rotating shaft 23 on one group of cabinet doors 3 carries the fixing plate 25 to rotate counterclockwise and moves to the right with the cabinet doors 3. The rotating shaft 23 on the other group of cabinet doors 3 carries the U-shaped plate 27 to rotate clockwise and moves to the left with the cabinet doors 3, so that the fixing plate 25 is inserted into the interior of the U-shaped plate 27. At the same time, the clamping block 28 on the U-shaped plate 27 is clamped and fixed with the clamping groove 26 on the fixing plate 25.

[0040] The second fixing mechanism includes a fixing member 40 arranged on one side of the support member 22, the fixing member 40 is fixedly connected to the cabinet door 3, the fixing member 40 is arranged in an L shape, one end of the fixing member 40 is fixedly installed with a fixing plate 29, the end surface of the fixing plate 29 is fixedly installed with a sleeve 30, the end of the sleeve 30 is slidably connected with a transmission column 31, the end of the transmission column 31 is fixedly installed with a fixing plate 23, a spring 32 is fixedly installed between the fixing plate 29 and the fixing plate 23, and a force plate 34 is arranged on one side of the fixing plate 23. A spring 36 is fixedly installed between the plate 34 and the fixed plate 33. A limit cavity 38 is opened inside the fixing part 40. A flexible rod 35 is slidably connected inside the limit cavity 38. One end of the flexible rod 35 is fixedly connected to the force-bearing plate 34. An insertion rod 37 is arranged on the front side of the fixing part 40. The other end of the flexible rod 35 is fixedly connected to the insertion rod 37. Two groups of fixing mechanisms 2 are arranged corresponding to the two groups of cabinet doors 3 and are arranged symmetrically. Two groups of slots 39 are opened on the front end surfaces of the fixing plate 25 and the U-shaped plate 27 corresponding to the two groups of insertion rods 37.

[0041] Secondly, when the two groups of cabinet doors 3 move toward each other, the fixing mechanism 2 thereon will also move toward each other. The two groups of force disks 34 will first collide with each other and squeeze the spring 2 36, causing the flexible rod 35 to slide inside the limiting cavity 38. When the U-shaped plate 27 on the fixing mechanism 1 is clamped and fixed with the fixing plate 25, the slots 39 thereon will also overlap, and the insertion rod 37 at the other end of the flexible rod 35 will be inserted into the slot 39, thereby performing secondary reinforcement on the U-shaped plate 27 and the fixing plate 25 to prevent the cabinet doors 3 from loosening and affecting the normal use of the equipment.

[0042] This solution significantly enhances the connection strength between the cabinet door 3 and the cabinet body 1 by setting a fixing mechanism 1 and a fixing mechanism 2. The double fixing mechanism not only ensures that the cabinet door 3 can fit the cabinet body 1 more firmly when closed, but also greatly improves the stability and durability of the entire cabinet body 1 structure. In this way, the cabinet body 1 provides a higher level of protection for the electrical equipment stored inside, effectively resists the impact of external shocks and vibrations, and reduces the risk of equipment failure due to physical damage.

[0043] Method of use: when the cabinet door 3 needs to be closed, the handle 8 on the threaded rod 7 is twisted to rotate the threaded rod 7. The thread groove on the outer surface of the threaded rod 7 is a bidirectional thread groove. Therefore, the two groups of threaded sleeves 9 connected by spiral transmission on both sides of the outer surface of the threaded rod 7 will move toward each other. Each group of threaded sleeves 9 will carry two groups of connecting rods 12 to move. The two groups of connecting rods 12 on the same side are rotatably connected to the top block 11 on the transmission rod 10, so that the two groups of transmission rods 10 will be driven to move toward each other. The clamping rods 13 at the ends of the transmission rods 10 will move toward each other synchronously. The two groups of clamping rods 13 are respectively fixedly connected to the two groups of cabinet doors 3. Therefore, the two groups of cabinet doors 3 will move toward each other, thereby closing the cabinet doors 3 and sealing the cabinet body 1.

[0044] Secondly, when the two groups of clamping rods 13 move toward each other, they will squeeze the transmission airbag 14 fixedly installed between the two groups of clamping rods 13, so that the gas inside the transmission airbag 14 enters the interior of the sealing airbag 16 through the connecting pipe 17, and the sealing airbag 16 will expand and expand toward the cabinet door 3 under the limiting action of the limiting shell 15, so as to be closely attached to the cabinet door 3, thereby increasing the airtightness between the cabinet body 1 and the cabinet door 3, and preventing moisture and dust from entering the interior of the cabinet body 1 through the gap and affecting the normal operation of the equipment inside the cabinet body 1;

[0045] The two groups of cabinet doors 3 move toward each other, and the gas inside the transmission airbag 14 enters the interior of the sleeve 19 through the connecting pipe 18, so that the piston plate 20 inside the sleeve 19 is lifted upward and the rack 21 is lifted. The rack 21 is meshed with the gear 24 on the rotating shaft 23, so the rotating shaft 23 rotates, and the rotating shaft 23 on one group of cabinet doors 3 carries the fixing plate 25 to rotate counterclockwise and moves to the right with the cabinet doors 3, and the rotating shaft 23 on the other group of cabinet doors 3 carries the U-shaped plate 27 to rotate clockwise and moves to the left with the cabinet doors 3, so that the fixing plate 25 is inserted into the interior of the U-shaped plate 27, and the clamping block 28 on the U-shaped plate 27 is clamped and fixed with the clamping groove 26 on the fixing plate 25;

[0046] Secondly, when the two groups of cabinet doors 3 move toward each other, the fixing mechanism 2 thereon will also move toward each other. The two groups of force disks 34 will first collide with each other and squeeze the spring 2 36, causing the flexible rod 35 to slide inside the limiting cavity 38. When the U-shaped plate 27 on the fixing mechanism 1 is clamped and fixed with the fixing plate 25, the slots 39 thereon will also overlap, and the insertion rod 37 at the other end of the flexible rod 35 will be inserted into the slot 39, thereby performing secondary reinforcement on the U-shaped plate 27 and the fixing plate 25 to prevent the cabinet doors 3 from loosening and affecting the normal use of the equipment.

[0047] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
