[0027] The existing photovoltaic panel pressing block assembly lacks effective temporary fixing mechanism after pre-installing on the track, and reliable pre-tightening force or limiting structure is not formed between the assembly and the track, so that it is easy to slide or displace when being slightly touched by external force, wind or unintentional collision of construction personnel, so that the photovoltaic panel needs to be frequently interrupted, re-adjusted and calibrated when being placed subsequently, which seriously affects the installation efficiency, in order to solve the above technical problems, the technical scheme is proposed as follows:

[0028] Referring to Figures 1-8 A photovoltaic panel installation pressing block assembly, its structure includes: pressing block 1, clamping block 3 for being buckled with track 2 slot, still include by the fastening bolt 4 that passes through the pressing block 1 from top to bottom and is connected with the clamping block 3, still have the abutting block 5 that is erected in the track 2 top between the pressing block 1 and the clamping block 3, the through hole 51 for the fastening bolt 4 to pass through is equipped in the middle of the abutting block 5, and the support arm 52 that extends outward along the width direction of the track 2 is equipped at the left and right ends respectively, the elastic piece 6 that separates the pressing block 1 and the abutting block 5 is still set on the fastening bolt 4;

[0029] When the fastening bolt 4 is screwed into the clamping block 3, the elastic piece 6 is deformed under pressure and provides pre-tightening force, then the clamping block 3 is clamped into the slot of the track 2, at this time the elastic piece 6 pushes the pressing block 1 to slide upward to the top end of the fastening bolt 4, and the abutting block 5 is tightly attached to the top of the track 2 under the action of its own gravity and the restoring force of the elastic piece 6, so that the support arm 52 and the clamping block 3 form a clamping structure to the both ends of the slot of the track 2, on the one hand, the temporary stable fixation of the pressing block assembly on the track can be realized, on the other hand, the gap for the frame of the photovoltaic panel to be clamped is formed between the pressing block 1 and the abutting block 5, which is convenient for subsequent rapid positioning and installation.

[0030] In use, there are two installation methods, such as Figure 6As shown, the first installation method is to first push the abutment block 5 upward along the fastening bolt 4 to compress the elastic element 6. Then, align the locking block 3 with the predetermined position of the track 2 and insert one end into the groove of the track 2 at a certain angle. Then, rotate it to a horizontal position so that it is fully locked into the groove. At this time, release the abutment block 5. The elastic element 6 rebounds and pushes the abutment block 5 downward, causing the support arm 52 of the abutment block 5 to fit against the top surface of the track 2. At this time, a clamping pre-tightening force is formed between the support arm 52 of the abutment block 5 and the locking block 3 to achieve temporary stable fixation of the pressure block assembly after installation, effectively preventing slippage or displacement.

[0031] like Figure 7 As shown, the second installation method is to directly align the locking block 3 with the predetermined position of the track 2 at a certain angle and insert one end into the groove of the track 2. At this time, the bottom of the support arm 52 of the abutment block 5 contacts the top surface of the track 2. As the locking block 3 gradually rotates to a horizontal state, the support arm 52 first drives the abutment block 5 to slide upward along the fastening bolt 4 and compress the elastic element 6. When the locking block 3 is fully embedded in the groove of the track 2, the elastic element 6 rebounds and unfolds, causing the abutment block 5 to move downward. Then, the two support arms 52 press tightly against the upper surface of the track 2 respectively, forming a stable pre-tightening structure with the locking block 3.

[0032] Both installation methods described above utilize the elastic element 6 and the abutment block 5 to form a pre-tightening effect, achieving automatic limiting and temporary fixation before the pressure block assembly is fully locked. This effectively avoids displacement problems caused by external force interference, improves the stability and work efficiency of the installation process, and reduces the frequency of adjustment and calibration by construction personnel, providing a reliable foundation for the subsequent precise installation of photovoltaic panels.

[0033] The top of the locking block 3 has an upwardly protruding boss 31, which is trapezoidal in shape and its width gradually increases from top to bottom. The bottom of the abutment block 5 has a limiting groove 53 that mates with the boss 31. The middle of the boss 31 has an internal threaded hole 32 that is threaded to the fastening bolt 4. Therefore, when the locking block 3 is fully embedded in the groove of the track 2, the elastic element 6 rebounds and pushes the abutment block 5 downward, so that the limiting groove 53 and the trapezoidal boss 31 are tightly engaged, preventing the abutment block 5 from rotating around the fastening bolt 4. This ensures that the support arm 52, the track 2, and the locking block 3 maintain a stable clamping state, effectively improving the reliability of the overall structural connection. At the same time, the inclined surface design of the trapezoidal boss 31 can guide the limiting groove 53 to automatically align during assembly, reducing installation difficulty and improving assembly efficiency.

[0034] The elastic element 6 is a helical spring; the top of the abutment block 5 has a positioning protrusion ring 54 for fixing one end of the helical spring. When in use, the helical spring is sleeved on the fastening bolt 4 and is axially limited by the positioning protrusion ring 54. Its other end abuts against the bottom of the pressure block 1, providing a continuous downward elastic preload to the abutment block 5.

[0035] The reinforcing rib 55 is arranged at the left and right ends of the top of the abutting block 5 and is connected with the positioning convex ring 54 and the supporting arm 52, extends along the length direction of the top surface of the abutting block 5, and is integrally formed with the positioning convex ring 54 and the supporting arm 52; the arrangement of the reinforcing rib 55 effectively improves the overall structural strength and deformation resistance of the abutting block 5.

[0036] The rod portion of the fastening bolt 4 is sequentially sleeved with the elastic pad 7 and the flat pad 8 from top to bottom, the flat pad 8 is located between the top of the pressing block 1 and the elastic pad 7, and the elastic pad 7 is located between the flat pad 8 and the head portion of the fastening bolt 4; after the photovoltaic panel is completely installed in place, the fastening bolt 4 is screwed, the anti-loosening performance of the connecting pair is enhanced through the cooperative action of the elastic pad 7 and the flat pad 8, and long-term stable work of the pressing block assembly is ensured.

[0037] The bottom of the pressing block 1 is provided with downwardly extending stop plates 11 towards the two sides of the width of the track 2, so that the left and right ends of the pressing block 1 are formed with clamping grooves matched with the edges of the photovoltaic panel, and the top of the clamping grooves is provided with anti-skid lines in a wave shape; in use, the edges of the photovoltaic panel are embedded in the clamping grooves, the stop plates 11 and the bottom of the pressing block 1 effectively disperse stress, prevent the photovoltaic panel from being broken under pressure, and improve the wind lifting resistance; the anti-skid lines can increase the friction between the pressing block and the photovoltaic panel, effectively prevent displacement caused by vibration or strong wind, and further ensure the installation stability.

[0038] The above only describes preferred embodiments of the present application and is not intended to limit the present application; for those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
