Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a new type of power generation system that directly converts solar energy into electrical energy. The photovoltaic junction box is the key connection device that connects solar modules in series in the photovoltaic system, and plays a major role in protecting solar modules from hot spots.

[0003] The patent specification with announcement number CN208656713U discloses a photovoltaic junction box. By setting a limit ring, a first fixing ring, and a second fixing ring, when the device is in use, the two cover plates can be fixed by a connecting rod and a telescopic spring. Then, by setting a fixing block and a pull ring, the device can be used to easily pull the connecting rod out from the inside of the limit ring. Then, through the action of the support spring, the cover plate can be easily opened under the elastic force of the support spring, so that the device can be easily disassembled.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, the connecting rod is pulled out from the inside of the limit ring, and then through the action of the support spring, the cover plate is easy to open under the elastic force of the support spring, but its operation process is relatively complicated, and it is time-consuming to reassemble the cover plate and the junction box. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a photovoltaic junction box, which solves the problem in the related art that it is inconvenient to reassemble a cover plate and a junction box body.

[0006] The technical solution of the utility model is as follows:

[0007] A photovoltaic junction box comprises a junction box body, wherein a disassembly assembly is arranged inside the junction box body, wherein the disassembly assembly comprises a placement slot formed at the upper end of the junction box body, a first through slot is formed through an inner wall on one side of the placement slot, a second through slot is formed through an inner wall on the other side of the placement slot, the first through slot and the second through slot are located on the same horizontal plane, sliding slots are formed on the inner walls on both sides of the placement slot, the sliding slots are connected to the first through slots, a movable slot is formed on one side of the junction box body, the movable slot is located below the second through slot, a cover plate is slidably connected to the interior of the junction box body, and a limiting rod is slidably connected to the interior of the side wall of the junction box body.

[0008] Preferably, a core element is fixedly connected to the bottom inner wall of the placement groove.

[0009] Preferably, a circular groove is provided on the inner wall of the second through groove.

[0010] Preferably, the circular groove is communicated with the movable groove.

[0011] Preferably, a handle is fixedly connected to one side of the cover plate, and a clamping block is fixedly connected to the other side of the cover plate, and a slot is formed through the upper end of the clamping block.

[0012] Preferably, the block corresponds to the second through groove, and the notch is communicated with the circular groove.

[0013] Preferably, a pull rod is fixedly connected to the outer surface of the limit rod, an oblique block is fixedly connected to the upper end of the limit rod, and a spring is fixedly connected to the lower end of the limit rod.

[0014] Preferably, the limiting rod is located inside the circular groove, the oblique block passes through the inside of the circular groove and the notch, and the lower end of the spring is fixedly connected to the bottom inner wall of the circular groove.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. The utility model presses the pull rod downward so that the pull rod moves downward along the movable groove. At this time, the pull rod drives the limit rod to move downward along the circular groove. After the inclined block is completely separated from the inside of the notch, the staff can pull the handle to drive the cover plate to move along the slide groove. At this time, the card block can be easily separated from the inside of the second through groove. At this time, the cover plate can be taken out from the inside of the junction box body, and the core components inside the junction box body can be conveniently maintained and repaired.

[0017] 2. The utility model places the card block at the first through-slot and then pushes the cover plate to move along the slide slot. After the card block enters the second through-slot, the card block will touch the inclined surface of the inclined block. As the card block continues to enter the second through-slot, the contact area between the card block and the inclined surface of the inclined block continuously increases. Under the action of the spring, the inclined block is continuously pressed downward along the circular groove. After the card block is completely immersed in the second through-slot, the notch and the circular groove are in a state of mutual communication, that is, the notch will not squeeze the oblique block, so that the limit rod and the oblique block enter the notch under the action of the spring, and because the vertical surface of the oblique block is attached to the inner side of the junction box body, the vertical surface of the oblique block forms a block against the card block when the handle is pulled, so that the card block cannot be separated from the inside of the second through-slot, and the process of pressing the pull rod downward is eliminated, thereby solving the problem of inconvenient and convenient reassembly between the cover plate and the junction box body.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, this embodiment provides a photovoltaic junction box, including a junction box body 1, wherein a disassembly assembly component 2 is arranged inside the junction box body 1.

[0027] like Figure 2 As shown, the disassembly assembly 2 includes a placement slot 21 opened at the upper end of the junction box body 1, a first through slot 22 is penetrated through the inner wall of one side of the placement slot 21, and a core component 211 is fixedly connected to the bottom inner wall of the placement slot 21.

[0028] like Figure 3As shown, a second through groove 24 is provided on the inner wall on the other side of the placement groove 21, and the first through groove 22 and the second through groove 24 are located on the same horizontal plane. Slide grooves 23 are provided on the inner walls on both sides of the placement groove 21, and the slide grooves 23 are connected with the first through groove 22. A movable groove 25 is provided on one side of the junction box body 1, and the movable groove 25 is located below the second through groove 24. A circular groove 241 is provided on the inner wall of the second through groove 24, and the circular groove 241 is connected with the movable groove 25. The slide grooves 23 are used to limit the two sides of the cover plate 26 to prevent the cover plate 26 from shifting in position when moving, so that the block 262 of the cover plate 26 cannot normally enter the interior of the second through groove 24.

[0029] like Figure 4 As shown, a cover plate 26 is slidably connected to the inside of the junction box body 1, a handle 261 is fixedly connected to one side of the cover plate 26, and a clamping block 262 is fixedly connected to the other side of the cover plate 26. A notch 2621 is penetrated through the upper end of the clamping block 262, and the clamping block 262 corresponds to the second through groove 24. The notch 2621 is connected to the circular groove 241. The handle 261 is used to save effort, so that the staff can drive the cover plate 26 to move along the slide groove 23.

[0030] like Figure 5 As shown, a limit rod 27 is slidably connected to the inner side wall of the junction box body 1, a pull rod 271 is fixedly connected to the outer surface of the limit rod 27, an oblique block 272 is fixedly connected to the upper end of the limit rod 27, and a spring 273 is fixedly connected to the lower end of the limit rod 27. The limit rod 27 is located inside the circular groove 241, and the oblique block 272 passes through the circular groove 241 and the inside of the notch 2621. The lower end of the spring 273 is fixedly connected to the bottom inner wall of the circular groove 241. The limit rod 27 is used to fix the junction box body 1 and the cover plate 26, the oblique block 272 is used to save effort, and the spring 273 is used to push the limit rod 27 and the oblique block 272 into the inside of the notch 2621.

[0031] The working principle and usage instructions of the utility model are as follows: When it is necessary to disassemble the cover plate 26 of the junction box body 1, the staff first needs to press the pull rod 271 downward to make the pull rod 271 move downward along the movable groove 25. At this time, the pull rod 271 will drive the limit rod 27 to move downward along the circular groove 241. After the inclined block 272 is completely separated from the inside of the notch 2621, the staff can pull the handle 261 to drive the cover plate 26 to move along the slide groove 23. At this time, the block 262 can be easily separated from the inside of the second through groove 24. At this time, the cover plate 26 can be taken out from the inside of the junction box body 1, and the core component 211 inside the junction box body 1 can be conveniently maintained and repaired. When it is necessary to cover the upper end of the placement groove 21 with the cover plate 26 again, the staff will place the block 262 at the first through groove 22, and then push the cover plate 26 to move along the slide groove 23. After the block 262 enters the second through groove 24, the block 262 touches the inclined surface of the oblique block 272. As the block 262 continues to enter the second through groove 24, the contact area between the block 262 and the inclined surface of the oblique block 272 increases continuously. Under the action of the spring 273, the oblique block 272 is continuously pressed downward along the circular groove 241. After the block 262 is completely immersed in the second through groove 24, the notch 2621 and the circular groove 241 are in a state of mutual communication, that is, the groove 2621 is in a state of mutual communication with the circular groove 241. The opening 2621 will not squeeze the inclined block 272, so that the limiting rod 27 and the inclined block 272 enter the slot 2621 under the action of the spring 273, and because the vertical surface of the inclined block 272 is attached to the inner side of the junction box body 1, when the handle 261 is pulled, the vertical surface of the inclined block 272 blocks the block 262, so that the block 262 cannot be separated from the inside of the second through slot 24, and the process of pressing the pull rod 271 downward is eliminated.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
