[0036] The working principle of the dry-hanging hidden-frame solar photovoltaic module frame is as follows:

[0037] Firstly, during the installation, the main bearing support is provided by the supporting structure 3 in the middle side of the bottom of the rectangular support frame 1, the screw rod 32 in the supporting structure 3 is rotated, the internal threaded block 33 and the rectangular sleeve 34 are driven to vertically lift, the bottom plate 35 and the load block 36 and the gasket 37 on the top are accurately adjusted in height, the gasket 37 contacts and tightly presses the back of the solar photovoltaic module, the load block 36 in the bottom of the supporting structure 3 can slightly rotate in the V-shaped groove 351, the toothed rubber sheet on the top side of the gasket 37 can adapt to the unevenness of the installation plane, eliminate the installation stress, provide the great friction and buffering effect, and ensure the stability of the module, meanwhile, the supporting structures 3 in the middle of the top, the left side and the right side of the rectangular support frame 1 are synchronously adjusted, the photovoltaic module is formed with auxiliary support and limiting from four sides, and a stable and comprehensive protection system is formed, so that the overall stability and the wind pressure resistance are greatly improved.

[0038] Second, after the initial support positioning, the horizontal position is fine-tuned and fixed. The operator presses the pressing rod 233 of the clamping assembly 23. The pressing rod 233 slides in the inclined groove 2341 of the sliding block 234 through the insertion column 2331 at the end of the pressing rod 233, converts the horizontal backward thrust into the downward movement of the sliding block 234, thereby forcing the clamping rod 235 fixed with the sliding block 234 to move downward against the elastic force of the spring 237, so that the triangular-shaped top end is completely withdrawn from the teeth of the rack 238, and the locking is released. At this time, keep the state, and slide the sliding sleeve 22 smoothly in the groove of the cross beam 21, thereby driving the locking assembly 24 at the rear to change the horizontal position to adapt to the mounting hole distance of photovoltaic components of different sizes. After adjusting to the right position, release the pressing rod 233, and the elastic force of the spring 237 will immediately push the clamping rod 235 upward to reset, and the clamping rod 235 is tightly clamped into the teeth of the rack 238 again, thereby firmly locking the sliding sleeve 22 at the current position of the cross beam 21, and ensuring that it will not be displaced in subsequent use;

[0039] Third, fasten the photovoltaic component through the locking assembly 24. The operator pulls the cross bar 243, and through the parallelogram structure formed by the first support rod 241, the second support rod 242, the cross bar 243 and the sliding sleeve 22, the cross bar 243 is always moved parallel to the fixed position of the photovoltaic component, until the strip-shaped sheet 244 at the front of the cross bar 243 is tightly attached to the fixed position of the photovoltaic component. The strip-shaped sheet 244 increases the contact area, so that the pressing force is uniformly distributed. Finally, the upper and lower sides of the strip-shaped sheet 244 are locked with the photovoltaic component using a bolt fastener, and the final reliable connection and fixation are completed.
