[0056] Embodiment 1

[0057] In order to achieve rapid installation of the photovoltaic panel 100 and improve the work efficiency of the installation of the photovoltaic panel 100, this embodiment provides a support frame.

[0058] like Figure 1-9As shown, the support frame includes a base 1, a fixed clamping assembly 2 and a movable clamping assembly 3. The base 1 can hold a plurality of photovoltaic panels 100 arranged side by side along a first direction; the fixed clamping assembly 2 includes two groups of fixing members 21 and a first clamping member 22 threadedly connected to the fixing member 21, the two groups of fixing members 21 are respectively fixed at both ends of the base 1 along the first direction, the fixing member 21 is provided with a first threaded through hole, one end of the first clamping member 22 passes through the first threaded through hole and can abut against the photovoltaic panel 100; the movable clamping assembly 3 includes a movable seat 31, a movable block 32, a first elastic member 33 and a movable clamping block 34, the movable seat 31 is slidably arranged on the base 1 along the first direction, the movable seat 31 is provided with a movable locking structure 37, the movable locking structure 37 can lock or unlock the movable seat 31 with the base 1, the movable seat 31 can be moved to the base 1, and the movable seat 31 can be moved to the base 1. The movable block 32 is connected to the top of the movable seat 31, and two groups of second clamping members 35 are provided on the movable block 32. The two groups of second clamping members 35 are arranged corresponding to two photovoltaic panels 100 respectively located on both sides of the movable block 32 along the first direction. The top of the second clamping member 35 is located above the movable block 32, and the bottom end of the second clamping member 35 passes through the movable block 32 and is located below the movable block 32. The first elastic member 33 is configured so that the second clamping member 35 always has a movement tendency away from the photovoltaic panel 100. The movable clamping block 34 can abut against the top of the two groups of second clamping members 35, and the movable clamping block 34 can be engaged with or disengaged from the movable block 32 so that the bottom end of the second clamping member 35 can abut against the corresponding photovoltaic panel 100. By using the first clamping member 22 on the fixed clamping assembly 2 to clamp one side of the photovoltaic panel 100, and then by moving the movable seat 31 in the movable clamping assembly 3 to move the second clamping member 35 on the movable block 32 to the other side of the photovoltaic panel 100, the movable seat 31 is slid and adjusted according to the size of the photovoltaic 100, so that the support frame can install photovoltaic panels 100 of different sizes. And by moving the locking structure 37, the movable seat 31 is locked together with the base 1, so as to prevent the movable seat 31 from sliding when clamping the photovoltaic panel 100. After that, the photovoltaic panel 100 is clamped by the second clamping member 35 to achieve rapid fixation of the photovoltaic panel 100, thereby improving the efficiency of the installation of the photovoltaic panel 100. And compared with drilling holes in the photovoltaic panel 100, the method of fixing the photovoltaic panel 100 with bolts simplifies the installation steps and reduces the cost of the installation work.

[0059] In this embodiment, the base 1 includes two load-bearing beams 11 and two mounting bases 12. The two load-bearing beams 11 are arranged in parallel and have a certain interval between each other. The two load-bearing beams 11 are used to carry the photovoltaic panel 100. The two mounting bases 12 are respectively fixed to the two ends of the bottom of the two load-bearing beams 11. A group of fixed clamping components 2 are respectively fixed at both ends of each load-bearing beam 11, and a plurality of groups of movable clamping components 3 that can slide on the load-bearing beam 11 are provided between the two groups of fixed clamping components 2 at both ends of each load-bearing beam 11, so as to ensure that the support frame can install multiple photovoltaic panels 100 at the same time. The first clamping member 22 is a bolt, and cooperates with the first threaded through hole on the fixing member 21, and the photovoltaic panel 100 is gradually clamped by screwing the first clamping member 22. A light hole is opened on the moving block 32, and the second clamping member 35 can be slidably arranged in the light hole. The second clamping member 35 adopts a rivet, and the first elastic member 33 is sleeved on the outside of the rivet rod and placed inside the light hole, so that the second clamping member 35 always has a tendency to move away from the photovoltaic panel 100, thereby ensuring that when the moving block 34 releases the second clamping member 35, the second clamping member 35 can automatically reset.

[0060] Furthermore, if Figure 2-4 As shown, one end of the moving pressing block 34 is hinged to the moving block 32, and the other end is clamped to the moving block 32. Thus, the moving pressing block 34 and the moving block 32 are quickly fixed.

[0061] In this embodiment, if Figure 1-4 As shown, when the photovoltaic panel 100 is placed, the movable pressing block 34 does not contact the second pressing member 35. When the photovoltaic panel 100 needs to be pressed, the movable pressing block 34 swings around the hinge between it and the movable block 32 to press the second pressing member 35 until the second pressing member 35 presses the photovoltaic panel 100 against the base 1, wherein the shape of the movable pressing block 34 can be a rectangular rod or a round rod.

[0062] Furthermore, if Figure 4 , Figure 6 As shown, a mounting groove is provided on the mobile pressing block 34, and a pressure rod handle 36 is also provided on the mobile pressing block 34. One end of the pressure rod handle 36 can be slidably inserted into the mounting groove, and the other end is provided with a clamping structure, and the clamping structure is located outside the mounting groove; a second elastic member 38 is also provided in the mounting groove, and the second elastic member 38 is configured to make the pressure rod handle 36 always have a movement tendency to retract the mobile pressing block 34; the mobile block 32 is provided with a clamping matching structure corresponding to the clamping structure, and the clamping structure can be clamped with the clamping matching structure, so that the mobile pressing block 34 clamps the second clamping member 35. By providing the pressure rod handle 36 on the mobile pressing block 34, it is convenient for the staff to operate the mobile pressing block 34, and by providing the clamping structure on the pressure rod handle 36 and the clamping matching structure on the mobile block 32, the mobile pressing block 34 and the mobile block 32 are quickly locked.

[0063] In this embodiment, if Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the pressure rod handle 36 is a T-shaped round rod including a vertical rod 361 and a cross rod 362. The second elastic member 38 is a spring, which is sleeved on the outside of the vertical rod 361. One end of the spring is connected to the cross rod 362, and the other end is connected to the bottom of the installation groove, so that the pressure rod handle 36 always has a movement tendency to retract the moving pressure block 34. And the cross rod 362 is a snap-fit ​​structure, and the snap-fit ​​matching structure is two blocks 321 arranged at one end of the moving block 32 away from the moving pressure block 34, and there is a certain interval between the two blocks 321, so that the vertical rod 361 can pass through the interval between the two blocks 321. When it is necessary to clamp the photovoltaic panel 100, the staff pulls the pressure rod handle 36 out of the installation groove. At this time, the spring is stretched, controlling the movable pressure block 34 to clamp the second pressure piece 35. When the movable pressure block 34 clamps the second pressure piece 35, the cross bar 362 of the pressure rod handle 36 is just below the two blocks 321. At this time, the operator releases the pressure rod handle 36, and the pressure rod handle 36 will retract under the action of the second elastic member 38. Then the first elastic member 33 will push the movable pressure block 34 upward, so that the cross bar 362 abuts against the bottom surfaces of the two blocks 321, thereby completing the locking of the movable pressure block 34 and the movable block 32.

[0064] Alternatively, if Figure 2 As shown, a limiting groove 322 corresponding to the moving pressing block 34 is provided on the moving block 32. When the moving pressing block 34 is engaged with the moving block 32, the moving pressing block 34 is received in the limiting groove 322, and both sets of second pressing members 35 are located in the limiting groove 322. When the moving pressing block 34 presses the second pressing member 35 and is engaged with the moving block 32, the moving pressing block 34 is located in the limiting groove 322, thereby ensuring that the upper surface of the moving block 32 is flat.

[0065] In this embodiment, the hinge point between the moving block 32 and the moving pressing block 34 is located in the limiting groove 322 , and the width of the limiting groove 322 corresponds to the width of the moving pressing block 34 , thereby ensuring that the moving pressing block 34 can only swing in the direction in which the limiting groove 322 extends.

[0066] Alternatively, if Figure 1-2 As shown, the moving block 32 is rotatably arranged on the top of the moving seat 31, and the base 1 is provided with a slideway 13 extending in a first direction, and the bottom end of the moving seat 31 is inserted into the slideway 13 and can slide along the slideway 13. The moving block 32 is rotatably arranged on the moving seat 31, so that the position of the second pressing member 35 on the moving block 32 can be adjusted according to the pressing position of the photovoltaic panel 100; and the slideway 13 is provided on the base 1 to ensure that the moving seat 31 can only slide along the direction in which the slideway 13 extends.

[0067] In this embodiment, the slideway 13 is provided on the load-bearing beam 11 , and the plurality of groups of movable pressing assemblies 3 can slide in the slideway 13 .

[0068] Furthermore, if Figure 1 , Figure 7 , Figure 8 As shown, the movable locking structure 37 includes: two abutting members 371, a cam 372, a rotating shaft 373 and a third elastic member 374. The movable seat 31 is provided with a through slot, and the two abutting members 371 are both slidably arranged in the through slot; the cam 372 is rotatably arranged in the through slot, and the two ends of the cam 372 are respectively abutted against the two abutting members 371; the rotating shaft 373 is rotatably arranged in the movable seat 31, one end of the rotating shaft 373 is connected to the movable block 32, and the other end of the rotating shaft 373 is connected to the cam 372, so that the cam 372 can rotate with the movable block 32 and push the two abutting members 371 to slide along the through slot, so that the two abutting members 371 extend from the two ends of the through slot respectively and abut against the two opposite side walls of the slideway 13 respectively; the third elastic member 374 is configured to make the two abutting members 371 always have a movement tendency to abut against the cam 372. With the cam 372 as a medium, the extension and retraction of the abutment member 371 can be achieved by controlling the rotation of the moving block 32, so that when the moving block 32 rotates the second clamping member 35 to the clamping position, the moving seat 31 and the base 1 are locked at the same time to prevent the moving seat 31 from sliding during the clamping process.

[0069] In this embodiment, the movable seat 31 includes a connecting block 311 and an inserting block 312. The movable block 32 is rotatably arranged at the top of the connecting block 311, and the inserting block 312 is fixedly connected to the bottom of the connecting block 311. A through groove is provided on the inserting block 312, and the through groove is divided into a circular groove 3122 and a square groove 3121. The circular groove 3122 is provided at both ends of the inserting block 312, and the square groove 3121 passes through the two circular grooves 3122. The abutment member 371 is circular and adapted to the circular groove 3122, and the circular abutment member 371 can slide in the circular groove 3122. A square slider 375 is fixedly arranged on one side where the two circular abutment members 371 are close to each other. The square slider 375 is adapted to the square groove 3121, and the square slider 375 can slide in the square groove 3121. The cam 372 is rotatably arranged in the square groove 3121 and is located between the two square sliders 375, and abuts against the two square sliders 375 at all times. The bottom of the square groove 3121 is provided with a guide groove 3123 corresponding to the two square sliders 375. The two square sliders 375 are provided with a guide plate 3751. The guide plate 3751 can slide in the guide groove 3123. The third elastic member 374 is sandwiched between the guide plate 3751 and the inner wall of the guide groove 3123 away from the cam 372. The third elastic member 374 is configured to make the two square sliders 375 always have a movement tendency to press against the cam 372. The cam 372 has a long axis and a short axis. When the two ends of the long axis of the cam 372 press against the square slider 375, the two circular abutting members 371 press against the inner wall of the slideway 13. When the two ends of the short axis of the two cams 372 press against the square slider 375, the two circular abutting members 371 retract into their respective circular grooves 3122. A through hole is provided on the connecting block 311, and the rotating shaft 373 can be rotatably penetrated on the connecting block 311. One end of the rotating shaft 373 is connected to the moving block 32, and the other end is connected to the cam 372, so that the cam 372 can rotate with the moving block 32, thereby controlling the long axis of the cam 372 to abut against the square slider 375, or the short axis of the cam 372 to abut against the square slider 375, so as to realize the extension and retraction of the abutting member 371.

By providing the rotation locking structure 39 between the moving block 32 and the moving seat 31, the moving block 32 is prevented from rotating when it is not needed, thereby driving the cam 372 to rotate, so that the moving seat 31 is unlocked from the base 1.

[0071] Furthermore, if Figure 6 , Figure 8 , Fig. 9As shown, the rotation locking structure 39 includes a latch 391 and a fourth elastic member 392. The latch 391 is slidably inserted into one of the moving block 32 and the moving seat 31. The other of the moving block 32 and the moving seat 31 is provided with a latch hole 393 corresponding to the latch 391. The fourth elastic member 392 is configured to make the latch 391 always have a movement tendency to be inserted into the latch hole 393.

[0076] In this embodiment, the first gasket 221, the second gasket 351 and the third gasket 3711 are all flexible spring gaskets.

[0077] In other embodiments, under the premise of ensuring that the photovoltaic panel 100 is not damaged, a flexible spring pad may be provided on any one of the first pressing member 22 , the second pressing member 35 and the abutting member 371 to reduce the cost.

[0078] In other embodiments, under the premise of ensuring that the photovoltaic panel 100 is not damaged, flexible spring pads may be provided on any two of the first pressing member 22 , the second pressing member 35 and the abutting member 371 to reduce costs.

[0079] During installation, it is only necessary to first fix the two bearing beams 11 to the roof of the building through the mounting base 12, and then lay the photovoltaic panels 100 one by one on the two bearing beams 11. When laying the first photovoltaic panel 100, first abut one side of the photovoltaic panel 100 against the fixing member 21, and then slide the moving seat 31 in the slide 13 and move to the other side of the photovoltaic panel 100. When the moving seat 31 is tightly against the other side of the photovoltaic panel 100, hold the moving block 32 and pull the latch handles 394 on both sides thereof, lift the latch 391, and then rotate the moving block 32, and drive the cam 372 to rotate through the rotating shaft 373, so that the two sides of the cam 372 squeeze the two abutting members 371, so that the abutting members 371 extend out and abut against the inner walls on both sides of the slide 13, and then release the latch handle 394 so that the two latches 391 are respectively inserted into the two latch holes 393 to lock the movable seat 31 and the base 1. After the movable block 32 rotates, the two sides of its bottom are just stuck on the upper part of the photovoltaic panel 100. After the movable seat 31 is fixed by the two abutments 371, one side of the next photovoltaic panel 100 is inserted under the other side of the movable block 32. At this time, the movable pressing block 34 can be pressed down so that the movable pressing block 34 presses the second pressing member 35, so that the two second pressing members 35 press the side frames of the two adjacent photovoltaic panels 100 respectively, and the snap-fit ​​structure on the pressure rod handle 36 is snapped with the snap-fit ​​matching structure on the movable block 32 to realize the fastening of the photovoltaic panel 100, and then the photovoltaic panels 100 are laid in turn and the photovoltaic panels 100 are pressed in turn by the movable pressing assembly 3, so that the rapid installation of the photovoltaic panel 100 can be completed.

[0080] Embodiment 2

[0081] The difference between this embodiment and the first embodiment is that the latch 391 is slidably arranged on the moving seat 31, the latch hole 393 is arranged on the moving block 32, the moving seat 31 is provided with a mounting hole, one end of the latch 391 is inserted in the mounting hole, and the other end is inserted in the latch hole 393, the fourth elastic member 392 is sandwiched between the mounting hole and the latch 391, and the fourth elastic member 392 is configured to make the latch 391 always have a movement tendency to be inserted into the latch hole 393. Compared with pulling the latch 391 upward to make the latch 391 slip out of the latch hole 393, pressing the latch 391 downward to make the latch 391 slip out of the latch hole 393 is more convenient for the staff to exert force.
