[0027] In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "left", "right", "rear", "lower left", "upper right", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] Specific implementation of the utility model: the special lock for installing photovoltaic panels comprises a lock body 1 for pressing the photovoltaic panel, the upper end surface of the lock body 1 is extended outwardly to be provided with a pressure block 11, and the pressure block 11 is symmetrically arranged on the lock body 1; preferably, the height of the lock body 1 is 38mm, and the lower end surface of the pressure block 11 is provided with a friction surface 111 for increasing friction; the lock body 1 is provided with a clamping assembly 2

[0029] With this structure, the pressing block 11 can move up and down under the action of the clamping assembly 2 to clamp the photovoltaic panel, and the pressing blocks 11 are arranged on both sides of the lock body 1 to clamp the photovoltaic panels on both sides of the lock body 1 at the same time.

[0030] As a preferred embodiment,

[0031] The clamping assembly 2 includes a stud 21 and a limiting fixing block 22; the limiting fixing block 22 passes through the lock body 1 and is rotatably connected to the lock body 1, and the stud 21 passes through the limiting fixing block 22 and is slidably connected to the limiting fixing block 22;

[0032] The side wall of the lock body 1 is provided with a limiting hole 12, and the limiting fixed block 22 is embedded in the limiting hole 12 by rotation. The limiting hole 12 is provided with a limiting structure for limiting the rotation range of the limiting fixed block 22; preferably, the limiting structure can be a limiting column or a limiting block extending inward from the inner wall of the limiting hole 12, and as long as the rotation range of the limiting fixed block 22 can be limited, it belongs to the protection scope of the present utility model. The limiting structure is arranged on one side of the limiting hole 12, and the limiting structure can limit the rotation range of the limiting fixed block 22. After the limiting fixed block 22 rotates 90 degrees, it will fit with the limiting structure; therefore, the limiting fixed block 22 will be engaged in the limiting hole 12 after rotating 90 degrees.

[0033] The stud 21 is located above the special-shaped slider 212 and is connected to a nut 211 through a thread. The special-shaped slider 212 is fixedly arranged below the thread. A clamping block 213 adapted to the long hole of the purlin is fixedly arranged at the lower end of the stud 21; the clamping block 213 is in the shape of a quadrangular pyramid, and the bottom surface of the clamping block 213 is fixedly arranged with the lower end surface of the stud 21, and the bottom surface of the clamping block 213 is a regular rectangle;

[0034] The position-limiting fixed block 22 is provided with a special-shaped slide groove 221 adapted to the special-shaped slider 212, the special-shaped slider 212 is embedded in the special-shaped slide groove 221 and slidably connected with the special-shaped slide groove 221, and the bottom wall of the special-shaped slide groove 221 is provided with a position-limiting platform 222 for limiting the position of the special-shaped slider 212. As a preferred embodiment, the special-shaped slide groove 221 and the special-shaped slider 212 are rectangular, and the special-shaped slide groove 221 and the special-shaped slider 212 can be set to polygonal shapes such as a five-pointed star and a hexagon in addition to a rectangle, as long as the special-shaped slide groove 221 can limit the axial rotation of the special-shaped slider 212 and play a guiding role, it belongs to the protection scope of the present utility model.

[0035] In the initial state, the clamping block 213, the limiting seat and the lock body 1 are in a parallel state, and the clamping block 213 rotates with the limiting fixing block 22. When the limiting fixing block 22 rotates and engages in the limiting hole 12, the clamping block 213 and the lock body 1 are in a vertical state.

[0036] By rotating the nut 211, the nut 211 drives the stud 21 and the limiting fixing block 22 to rotate together through the thread. After the limiting fixing block 22 rotates, it will contact the limiting structure; therefore, the limiting fixing block 22 will be engaged in the limiting hole 12 after rotating; then continue to rotate the nut 211, because the special-shaped slider 212 is engaged in the special-shaped slide groove 221, the special-shaped slider 212 will be displaced along the special-shaped slide groove 221 under the action of the nut 211. At this time, the stud 21 will move upward under the action of the nut 211, thereby driving the clamping block 213 to move upward.

[0037] For the existing lock installation mode, the photovoltaic panel is installed and fixed by an automatic photovoltaic panel installation robot. However, the existing automatic photovoltaic panel installation robot cannot lock the nut under the photovoltaic panel block 11, so a staff member is required to assist in locking, which not only limits the automated installation, but also makes the installation troublesome and labor-intensive.

[0038] The locking bolt 22 is provided with a shaped slot 221 which is used to limit the rotation of the locking bolt 22. The locking bolt 22 is provided with a shaped slot 221 which is used to limit the axial rotation of the locking bolt 22. Under the action of the shaped slot 221 and the shaped slot 221, the locking bolt 22 is automatically engaged in the shaped slot 12 after the locking bolt 22 is rotated. The shaped slot 221 plays a guiding role after the locking bolt 22 is engaged. The shaped slider 212 moves along the shaped slot 221, thereby driving the clamping block 213 to move for tightening the photovoltaic panel. Therefore, the problem that the nut under the photovoltaic panel pressing block 11 cannot be tightened during the automated installation process is solved. This not only facilitates the grabbing of the robot, but is also more suitable for one-time locking in one direction. The problem of the locking bolt relying on manual locking is avoided from a structural point of view, which greatly simplifies the installation process, reduces the difficulty of the installation process, and saves labor.

[0039] It should be noted that the utility model is a special lock for installing photovoltaic panels.

[0040] First, place the photovoltaic panel on the photovoltaic panel mounting frame, wherein the photovoltaic panel mounting frame is composed of purlins with long holes, and then place the lock body 1 between the two photovoltaic panels to play a connecting role, so that the two photovoltaic panels can be firmly connected together and fixed on the mounting frame at the same time; insert the clamping block 213 into the long holes of the purlin, at this time, there are photovoltaic panels placed on both sides of the lock body 1, turn the nut 211, and the nut 211 will drive the stud 21 and the limit fixing block 22 to rotate together, and after the limit fixing block 22 rotates, it will be aligned with the limit structure. Contact; therefore, the limiting fixing block 22 will be engaged in the limiting hole 12 after being rotated; then continue to rotate the nut 211, the stud 21 will move upward under the action of the nut 211, and since the special-shaped slider 212 is engaged in the special-shaped slide groove 221, the special-shaped slider 212 will move upward along the special-shaped slide groove 221 under the action of the nut 211, thereby driving the clamping block 213 to move upward, and when the nut 211 is tightened, the clamping block 213 is tightly fitted with the inner wall of the purlin where the photovoltaic panel is placed, and the pressing block 11 is tightly fitted with the photovoltaic panels on both sides of the lock body 1.

[0041] When disassembly is required, the nut 211 is rotated in the opposite direction, and the nut 211 will drive the stud 21 and the limiting fixing block 22 to rotate together. At this time, the clamping block 213 and the inner wall of the purlin where the photovoltaic panel is placed are no longer fitted, and the pressing block 11 and the photovoltaic panels on both sides of the lock body 1 are also no longer fitted, and the lock body 1 can be removed.
