Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A relay for solar photovoltaic that can be combined with each other, including: a mounting plate 111 and a mounting seat 112, the side wall of the mounting plate 111 is fixedly connected to the mounting seat 112, the upper end of the mounting plate 111 is provided with a mounting structure 2, and an adjustment structure 3 is provided above the mounting plate 111. The mounting structure 2 includes a first limit frame 211, the first limit frame 211 is arranged at the upper end of the mounting plate 111, the upper end of the mounting plate 111 is provided with a second limit frame 212, the upper end of the mounting plate 111 is provided with a relay body 213, the top of the relay body 213 is integrally formed with a pin 214, the side wall of the relay body 213 is fixedly connected to a mounting block 215, the mounting block 215 is inserted into the first limit frame 211 and the second limit frame 212, a plug rod 216 is inserted into the mounting block 215, and the upper end of the plug rod 216 is fixedly connected to the pull rod 21 7. The insert rod 216 and the pull rod 217 can slide in the slideways provided inside the first limit frame 211 and the second limit frame 212. The end of the insert rod 216 away from the mounting block 215 is inserted into the insert cavity 218. The insert cavity 218 is provided inside the first limit frame 211 and the second limit frame 212. With this design, when multiple groups of relays are used in combination, multiple groups of relay bodies 213 are installed on the upper end of the mounting plate 111. First, pull the pull rod 217 to drive the insert rod 216 to move away from the mounting block 215, and then install the relay body 213 to the upper end of the mounting plate 111. At the same time, the mounting block 215 is inserted into the first limit frame 211 and the second limit frame 212. Then, the insert rod 216 is restored to its original position again, so that the insert rod 216 enters the mounting block 215, and the installation of the relay body 213 is completed.

[0024] Furthermore, one end of the plug rod 216 away from the mounting block 215 is fixedly connected to a first spring 219, and one end of the first spring 219 away from the plug rod 216 is fixedly connected to the inner wall of the insertion cavity 218. Through this design, when multiple groups of relays are used in combination, the multiple groups of relay bodies 213 are installed on the upper end of the mounting plate 111, and the pull rod 217 is first pulled to drive the plug rod 216 to move away from the mounting block 215, and then the relay body 213 is installed to the upper end of the mounting plate 111. At the same time, the mounting block 215 is inserted into the first limit frame 211 and the second limit frame 212. At this time, the first spring 219 is in a compressed and force-accumulating state. The pull rod 217 is released, and the elastic force of the first spring 219 can automatically drive the plug rod 216 to enter the mounting block 215, so that the installation of the relay body 213 can be completed conveniently.

[0025] Furthermore, a first slider 220 is fixedly connected to the side wall of the insertion rod 216. The first slider 220 is inserted into the first slide groove 221. The first slide groove 221 is opened inside the first limit frame 211 and the second limit frame 212. Through this design, when the insertion rod 216 moves, the first slider 220 moves synchronously inside the first slide groove 221, thereby realizing the limiting effect on the insertion rod 216 and making its movement more stable.

[0026] Furthermore, the adjustment structure 3 includes an adjustment rod 311, which is fixedly connected to the outer wall of the first limit frame 211, and an adjustment column 312 is fixedly connected to the outer wall of the second limit frame 212. The adjustment column 312 is inserted into the adjusting rod 311, and a fixing rod 313 is inserted into the adjusting column 312. The fixing rod 313 is fixedly set inside the adjusting rod 311, and a second spring 314 is wound around the surface of the fixing rod 313. Through this design, when multiple groups of relay bodies 213 are installed, due to different relay models, the first limit frame 211 can be pulled to move away from the relay body 213, and the distance between the first limit frame 211 and the second limit frame 212 can be adjusted so that the relay body 213 can be placed between the second limit frame 212 and the first limit frame 211, which is convenient for installing relay bodies 213 of different models.

[0027] Furthermore, a damper 315 is connected to one end of the second spring 314. Through this design, when the first limit frame 211 is pulled to move, the adjustment rod 311 is driven to move synchronously, causing the second spring 314 to undergo elastic deformation. The second spring 314 transfers the force to the damper 315. The damper 315 can be used to decompose the force to avoid repeated vibration of the second spring 314.

[0028] Furthermore, the side wall of the adjusting column 312 is fixedly connected to the limit block 316, and the limit block 316 is inserted into the limit groove 317. The limit groove 317 is opened inside the adjusting rod 311. Through this design, when the adjusting rod 311 moves, the limit block 316 moves synchronously inside the limit groove 317, making its movement more stable.

[0029] Furthermore, a second slider 318 is fixedly connected to the bottom end of the first limit frame 211, and the second slider 318 is inserted into a second slide groove 319. The second slide groove 319 is opened inside the mounting plate 111. Through this design, when the first limit frame 211 moves, the second slider 318 slides synchronously inside the second slide groove 319, thereby realizing the limiting effect on the first limit frame 211 and making its sliding more stable.

[0030] Working principle:

[0031] When multiple groups of relays are used in combination, multiple groups of relay bodies 213 are installed on the upper end of the mounting plate 111. First, pull the pull rod 217 to drive the insertion rod 216 to move away from the mounting block 215, and then install the relay body 213 to the upper end of the mounting plate 111. At the same time, the mounting block 215 is inserted into the first limit frame 211 and the second limit frame 212. At this time, the first spring 219 is in a compressed and force-accumulating state. Release the pull rod 217, and use the elastic force of the first spring 219 to automatically drive the insertion rod 216 into the mounting block 215, so that the installation of the relay body 213 can be completed conveniently.

[0032] When installing multiple groups of relay bodies 213, due to different relay models, the first limit frame 211 can be pulled to move away from the relay body 213, and the distance between the first limit frame 211 and the second limit frame 212 can be adjusted so that the relay body 213 can be placed between the second limit frame 212 and the first limit frame 211, which is convenient for installing relay bodies 213 of different models. When the first limit frame 211 is pulled to move, the adjustment rod 311 is driven to move synchronously, causing the second spring 314 to undergo elastic deformation. The second spring 314 transmits the force to the damper 315, and the damper 315 can be used to decompose the force to avoid repeated vibration of the second spring 314. The operation is now completed.
