[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] Embodiment 1

[0029] Please refer to Figure 1 and 2 As shown, the present utility model is a solar controller, including a controller body 1. A sliding groove 101 is formed in the back wall of the controller body 1, and two mounting plates 2 are slidably connected in the sliding groove 101, and a transmission gear 3 is rotatably connected. The sliding groove 101 has a T-shaped groove structure, and the mounting plate 2 is matched with the sliding groove 101 to achieve sliding connection.

[0030] As Figure 3 and 4 shown, one end of each of the two mounting plates 2 extends out of the controller body 1 from both ends of the sliding groove 101, and mounting holes 201 are provided. The other ends of the two mounting plates 2 are both connected with racks 202 meshing with the transmission gear 3. By the transmission of the transmission gear 3, the synchronous movement towards and away from each other of the two mounting plates 2 is realized, facilitating the adaptation of the two mounting plates 2 to different mounting positions.

[0031] Among them, as Figure 5 shown, threaded holes are provided on the inner bottom surface of the sliding groove 101, and through holes 102 corresponding to the positions of the threaded holes are provided on the back wall of the controller body 1. The through holes 102 are countersunk holes for inserting screws 4 that cooperate with the threaded holes through the through holes 102.

[0032] The mounting plate 2 is provided with straight slot openings 203 with clearance fit with the screws 4 for limiting the sliding position of the mounting plate 2 through the cooperation of the screws 4 and the straight slot openings 203, which can avoid the situation that the mounting plate 2 accidentally slides out of the controller body 1.

[0033] Meanwhile, the structural strength of the thin wall at the position where the sliding groove 101 is provided on the controller body 1 can also be improved. And, the screws 4 are sleeved with bushings 401, and there is a clearance fit between the outer wall of the bushings 401 and the inner wall of the straight slot openings 203, thereby avoiding the wear of the screws 4 caused by the sliding of the mounting plate 2.

[0034] Four to six cushion blocks 103 are fixedly connected to the back wall of the controller body 1. The cushion blocks 103 can be rubber pads. By abutting the cushion blocks 103 against the mounting surface, the mounting stability of the controller body 1 can be improved. When installing, when one of the mounting plates 2 is pushed or pulled, the rack 202 drives the transmission gear 3 to rotate, and the transmission gear 3 drives the rack 202 on the other mounting plate 2, thereby realizing the synchronous movement of the two mounting plates 2, thus facilitating the flexible adaptation to the mounting position.

[0035] In addition, a rotating shaft 301 is rotatably connected in the sliding groove 101, and the transmission gear 3 is fixedly connected to the rotating shaft 301. The rotation of the transmission gear 3 is realized through the rotating shaft 301. A slit is axially provided in the rotating shaft 301, and a hairspring 302 is connected to the rotating shaft 301. The central position of the hairspring 302 is snapped into the slit, and the outer end is fixed by screws or pins.

[0036] The rotating shaft 301 is driven to rotate by the hairspring 302, and the two mounting plates 2 are driven by the transmission gear 3 in the direction of extending out of the controller body 1, so that the mounting plates 2 have an automatic reset effect, enabling the two mounting plates 2 to squeeze the bolts for installation and fixation, further improving the mounting stability.

[0037] Meanwhile, the mounting hole 201 is a calabash-shaped hole arranged parallel to the sliding direction of the mounting plate 2. The mounting hole 201 is set as a calabash-shaped hole, so that when the bolt is pre-fixed, the calabash-shaped hole can penetrate through the mounting plate 2. After the mounting plate 2 is loosened, driven by the clockwork spring 302, the two mounting plates 2 extend outward toward the outside of the controller body 1, and thus the narrower end of the calabash-shaped hole is stuck on the bolt to achieve rapid installation and facilitate subsequent disassembly and maintenance, thereby greatly improving the overall practicability and convenience of use.
