DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0036] Embodiment 1: A reinforcing connector adapted for photovoltaic purlins of various sizes, such as Figure 1 and Figure 2 As shown, it includes a connecting sleeve with adjustable size, and a positioning plate 3 and an airbag clamping column 11 arranged on each inner wall of the connecting sleeve, a screw 31 is rotatably provided on the positioning plate 3, a clamping groove 42 for clamping with the airbag clamping column 11 is provided on the side of the photovoltaic purlin 4, and a plurality of screw tubes 41 corresponding to the corresponding screws 31 are provided on the end surface of the photovoltaic purlin 4;

[0037] like Figure 4 and Figure 6As shown, the positioning plate 3 has a cavity inside, and the cavity is provided with a first airbag 341 connected to the inner wall of one side of the cavity, an energy storage airbag 342 connected to the first airbag 341 through a first pipe, and a vertically arranged air groove 333, the air groove 333 is connected to the energy storage airbag 342 through a second pipe, and a pressure relief valve 343 is provided on the energy storage airbag 342, the pressure relief valve 343 is an existing device available on the market, and the first pipe and the second pipe are both commercially available one-way air inlet pipes;

[0038] like Figure 4 and Figure 7 As shown, a driving rod 332 is provided in a sliding seal in the air groove 333, and an inflatable hook 336 is provided on the top of the driving rod 332. The inflatable hook 336 is connected to the bottom of the air groove 333 through a first connecting tube 337, and a second connecting tube 335 is provided at the bottom of the air groove 333 at one end thereof and connected to the inside thereof, and a blocking plate 334 is provided at the bottom of the driving rod 332 for controlling the opening or closing of the second connecting tube 335 by moving up and down, and an extension groove 338 is provided in the air groove 333 for the blocking plate 334 to extend into, and the extension groove 338 is connected to the bottom of the cavity.

[0039] like Figure 4 and Figure 8 As shown, the cavity is provided with a snap ring 344 that cooperates with the inflation hook 336, and a rack 331 connected to the driving rod 332 through a connecting rod is provided on one side of the air groove 333 in parallel. The rack 331 is connected to the cavity by sliding up and down through a limiting rod. The screw 31 is provided with an extension rod 311 extending into the cavity, and the extension rod 311 is sleeved with a cam 34 for squeezing the airbag 341 and a gear 33 for driving the rack 331 to slide up and down.

[0040] like Figure 5 As shown, the second connecting pipe 335 is embedded in the inner wall of the connecting sleeve and communicated with the airbag clamping column 11. The connecting sleeve is provided with a deflation switch 111 communicated with the airbag clamping column 11. The deflation switch 111 can be a commercially available push-type deflation valve.

[0041] like Figure 1 As shown, the connecting sleeve is composed of four side plates 1, and two adjacent side plates 1 are connected by a plurality of guide rods 2, and the two ends of the guide rods 2 are respectively slidably connected with the slide rails 12 provided on the two adjacent side plates 1;

[0042] like Figure 1 and Figure 3 As shown, the positioning plate 3 is provided with a third airbag 32 which is in compression contact with the end of the photovoltaic purlin 4, and the slide rail 12 is provided with a plurality of second airbags 121 for fixing the guide rod 2, and the plurality of second airbags 121 are all connected to the corresponding third airbags 32.

[0043] The working principle of the above-mentioned reinforcing connector adapted to photovoltaic purlins of multiple sizes is as follows: the top side panel 1 is slid upward along the slide rail 12 of the right side panel 1 along the guide rod 2, and the right side panel 1 is then slid to the right along the slide rail 12 of the top side panel 1 along the guide rod 2, and the sliding does not affect each other, and then the photovoltaic purlin 4 is inserted into the connecting sleeve, and each side panel 1 is fitted with the side wall of the photovoltaic purlin 4, and the screw tube 41 on the end face of the photovoltaic purlin 4 is sleeved with the screw 31 on the positioning plate 3 in the side panel 1. In the process of the photovoltaic purlin 4 going deeper, the third airbag 32 is squeezed, and the second airbag 121 bulges out to clamp the guide rod 2, so that the position of each side panel 1 is fixed;

[0044] At the same time, the rotation of the screw 31 drives the cam 34 to squeeze and store energy on the first air bag 341 that has been squeezed and then restored to its original state, so that the gas squeezed from the first air bag 341 enters the energy storage air bag 342, the air groove 333 and the first connecting pipe 337 in sequence. At the same time, the screw 31 drives the gear 33 to rotate synchronously, so that the rack 331 continues to drive the driving rod 332 to move upward. Before the rotation of the screw 31 is completed, the energy storage air bag 342 continues to store energy. The air bag clamping column 11 is not connected to the air groove 333 at this time, so as not to contact the side wall of the photovoltaic purlin 4 and avoid wear on the photovoltaic purlin 4. During the upward movement of the driving rod 332, the driving rod 33 The inflatable part on the opposite surface of the inflatable hook 36 at the top gradually extends and contacts and closes, and in this process, the gas filling in the gas groove 333 also provides a part of the upward support for the driving rod 332, until the screw rod 31 is rotated completely, and the driving rod 332 moves up to the highest point to make the inflatable hook 36 completely closed in the clamp ring 344, thereby being locked with the clamp ring 344. At the same time, the second connecting pipe 335 is also connected with the gas groove 333, so that the gas is released and transmitted to the airbag clamp column 11 so that it is clamped with the side wall of the photovoltaic purlin 4, completing the double clamping of the end face and side face of the connecting sleeve and the photovoltaic purlin 4, and strengthening the connection stability of the connecting sleeve and the photovoltaic purlin 4;

[0045] When the photovoltaic purlin 4 needs to be disassembled later, the deflation switch 111 is pressed to deflate the airbag column 11, the air groove 333 and the first connecting tube 337. Then, the driving rod 332 drives the rack 331 downward under the action of gravity, thereby reversing the screw 31 to make the photovoltaic purlin 4 easier to detach from the connecting sleeve, thereby enhancing the convenience of disassembly.

[0046] Embodiment 2: This embodiment differs from Embodiment 1 in that Fig. 9 As shown, a first magnetic sheet 3331 is provided at the bottom of the air groove 333, and a second magnetic sheet 3321 magnetically attracted to the first magnetic sheet 3331 is provided at the bottom of the driving rod 332;

[0047] A touch sensor and a controller are provided at the bottom of the extension groove 338, and a display for displaying the deflation status is provided on the outer wall of the connecting sleeve. The touch sensor and the display are electrically connected to the controller, and the touch sensor, the display and the controller are all commercially available devices.

[0048] The working principle of this embodiment is different from that of embodiment 1 in that the first magnetic piece 3331 and the second magnetic piece 3321 can speed up the descending efficiency of the driving rod 332 after it is separated from the retaining ring 344, thereby speeding up the efficiency of reversing the screw 31, enhancing the convenience of disassembling the photovoltaic purlin 4, and by setting a touch sensor, after the blocking plate 334 descends to the lowest point with the driving rod 332, it can be indicated on the display whether the deflation is completed, so that the staff can clearly understand the disassembly and assembly status of the photovoltaic purlin 4.

[0049] Embodiment 3: This embodiment differs from Embodiment 2 in that Fig.10 As shown, the guide rod 2 is provided with a suction cup 23 for connecting the guide rod 2 and the photovoltaic purlin 4, and the suction cup 23 is longitudinally slidably connected to the guide rod 2 through the sliding rod 21. The guide rod 2 is hollow inside and a driving block 22 is fixedly sleeved on the sliding rod 21 located inside the guide rod 2, and the driving block 22 is provided with a protrusion that penetrates the side wall of the guide rod 2 and is used for friction contact with the second airbag 121; it can be understood that the extrusion stroke of the driving block 22 by the second airbag 121 is the longitudinal distance between the bottom of the guide rod 2 and the inner wall of the side plate 4, which is also the longitudinal distance between the guide rod 2 and the surface of the photovoltaic purlin 4, and the protrusion amount of the second airbag 121 is sufficient to squeeze the driving block 22 to the bottom of the guide rod 2 and prevent the guide rod 2 from sliding left and right.

[0050] The working principle of this embodiment is different from that of Embodiment 2 in that, when the second airbag 121 is inflated and protrudes, the driving block 22 is first squeezed to drive the suction cup 23 to move downward and engage with the photovoltaic purlin 4, thereby filling the gap between the guide rod 2 and the photovoltaic purlin 4 and improving the connection strength between the connecting sleeve and the photovoltaic purlin 4.
