Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket accessories technology, specifically a guide rail anti-offset buckle for a photovoltaic bracket. Background Technology

[0002] As a key component supporting photovoltaic (PV) panels, the stability of the PV mounting system directly affects power generation efficiency and system lifespan. The guide rails are crucial components in the PV mounting system, used for precise positioning and installation of the PV panels. Any misalignment of the guide rails can trigger a series of serious problems. In the PV mounting system, the guide rail clips securely install the PV modules onto the mounting system, ensuring their stability and safety.

[0003] For example, utility model application CN202320609581.3 discloses a guide rail connecting buckle and a locking structure for photovoltaic panel installation. This utility model includes a pressure block, a fastener, and the guide rail connecting buckle. The pressure block has a second mounting hole, and the fastener passes through the first and second mounting holes to lock the pressure block and the guide rail connecting buckle together. This locking structure is time-saving and labor-saving to install, meets the tolerance requirements of the guide rail slot, and has a wider range of applications. However, the fastener is not equipped with an anti-rotation structure. Under long-term strong vibration, the bolt may loosen due to self-rotation, leading to a decrease in the clamping force of the rotating arm and increasing the risk of guide rail misalignment.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a guide rail anti-displacement buckle for photovoltaic brackets. Utility Model Content

[0005] The purpose of this invention is to provide a guide rail anti-offset buckle for a photovoltaic bracket to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide rail anti-offset buckle for a photovoltaic bracket, comprising a guide rail and a positioning shell. A photovoltaic panel is placed on top of the guide rail, and a pressure block is provided on the top of the photovoltaic panel. A bolt is connected to the screw hole in the middle of the pressure block, and a transmission rod is fixed to the bottom of the bolt. A turntable is sleeved and fixed on the outside of the bolt, and a return spring is provided at the bottom of the turntable. An anti-rotation plate is provided at the other end of the return spring, and an anti-loosening pin is fixed through the middle of the anti-rotation plate. A slot is opened on the top of the pressure block, and the positioning shell is placed in the slot of the guide rail. An installation block is fixed at the openings on both sides of the positioning shell.

[0007] Furthermore, the side of the pressure block has an inverted L-shaped structure, and the slots are distributed in a ring at equal intervals about the top of the pressure block.

[0008] Furthermore, a locking arm is hinged to the middle of the mounting block one via a pin, and a support arm is hinged to the other end of the locking arm via a pin.

[0009] Furthermore, the end of the support arm away from the clamping arm is hinged to a mounting block two via a pin, and a lead screw nut is provided on the outside of the mounting block two.

[0010] Furthermore, bearings are also provided in the through holes at the top and bottom of the positioning shell, and a trapezoidal lead screw is inserted in the lower bearing. A transmission cylinder is fixed to the top of the trapezoidal lead screw, and a lead screw nut is connected to the outside of the trapezoidal lead screw.

[0011] Furthermore, the trapezoidal lead screw, transmission cylinder, transmission rod, and bolt are coaxially arranged, and the external structure of the transmission rod matches the internal structure of the transmission cylinder.

[0012] Furthermore, the turntable is elastically connected to the anti-rotation plate via a return spring, and the outer diameter of the anti-loosening pin matches the inner diameter of the slot.

[0013] This utility model provides a guide rail anti-offset buckle for a photovoltaic bracket, which has the following beneficial effects:

[0014] 1. This utility model tightens the bolt in the screw hole in the middle of the pressure block so that the pressure block is close to the edge of the photovoltaic panel. Then, the anti-loosening pin is loosened. The anti-loosening pin is inserted into the slot by the push of the return spring to stop the rotating plate, forming a double anti-loosening mechanism of mechanical locking and elastic pre-tightening. This reduces the bolt loosening rate, maintains the clamping force of the clamping arm, and avoids fluctuations in power generation efficiency caused by photovoltaic panel misalignment. During maintenance, only the anti-loosening pin needs to be pulled out for adjustment. It is suitable for various installation environments.

[0015] 2. In this utility model, the photovoltaic panel is placed above the guide rail, and an inverted L-shaped pressure block covers its top. Bolts are inserted into the screw holes of the pressure block, and the bottom transmission rod is adapted to the transmission cylinder. Then, rotating the bolt drives the transmission rod, transmission cylinder and trapezoidal screw to rotate stably, so that the screw nut drives the second installation block to move. Through the linkage of the support arm and the clamping arm, the clamping arm can clamp and position the guide rail, ensuring the accurate installation position of the photovoltaic panel.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, a guide rail anti-offset buckle for a photovoltaic bracket includes a guide rail 1 and a positioning shell 4. A photovoltaic panel 2 is placed on top of the guide rail 1, and a pressure block 3 is provided on the top of the photovoltaic panel 2. A bolt 12 is connected to the screw hole in the middle of the pressure block 3, and a transmission rod 13 is fixed to the bottom of the bolt 12. A turntable 14 is sleeved and fixed on the outside of the bolt 12, and a return spring 15 is provided at the bottom of the turntable 14. An anti-rotation piece 16 is provided at the other end of the return spring 15, and an anti-loosening pin 17 is fixed through the middle of the anti-rotation piece 16. A slot 18 is opened on the top of the pressure block 3. The positioning shell 4 is placed in the slot of the guide rail 1, and mounting blocks 5 are fixed at the openings on both sides of the positioning shell 4. The side of the pressure block 3 has an inverted L-shaped structure, and the slots 18 are distributed in a ring at equal intervals around the top of the pressure block 3.

[0022] The specific operation is as follows: tighten the bolt 12 in the screw hole in the middle of the pressure block 3 so that the pressure block 3 is close to the edge of the photovoltaic panel 2. Then loosen the anti-loosening pin 17. The anti-loosening pin 17 is inserted into the slot 18 by the push of the return spring 15 to stop the rotating plate 16. This forms a double anti-loosening mechanism of mechanical locking and elastic pre-tightening, thereby reducing the loosening rate of the bolt 12 and maintaining the clamping force of the clamping arm 6. This avoids fluctuations in power generation efficiency caused by the offset of the photovoltaic panel 2. During maintenance, it is only necessary to pull out the anti-loosening pin 17 for adjustment. It is suitable for various installation environments.

[0023] like Figures 1 to 3As shown, a locking arm 6 is hinged to the middle of mounting block 5 via a pin, and a support arm 7 is hinged to the other end of the locking arm 6 via a pin. Mounting block 8 is hinged to the end of the support arm 7 away from the locking arm 6 via a pin. A screw nut 9 is provided on the outside of mounting block 8. Bearings 19 are also provided in the through holes at the top and bottom of the positioning shell 4. A trapezoidal screw 10 is inserted in the lower bearing 19, and a transmission cylinder 11 is fixed to the top of the trapezoidal screw 10. A screw nut 9 is connected to the outside of the trapezoidal screw 10. The trapezoidal screw 10, transmission cylinder 11, transmission rod 13 and bolt 12 are coaxially arranged, and the external structure of the transmission rod 13 matches the internal structure of the transmission cylinder 11. The turntable 14 is elastically connected to the anti-rotation plate 16 via a return spring 15. The outer diameter of the anti-loosening pin 17 matches the inner diameter of the slot 18.

[0024] The specific operation is as follows: place the photovoltaic panel 2 above the guide rail 1, cover its top with the inverted L-shaped pressure block 3, insert the bolt 12 into the screw hole of the pressure block 3, and connect the bottom transmission rod 13 with the transmission cylinder 11. Then rotate the bolt 12 to drive the transmission rod 13, the transmission cylinder 11 and the trapezoidal screw 10 to rotate stably, so that the screw nut 9 drives the installation block 8 to move. Through the linkage of the support arm 7 and the clamping arm 6, the clamping arm 6 can clamp and position the guide rail 1, ensuring the accurate installation position of the photovoltaic panel 2.

[0025] In summary, when using the anti-offset buckle of the photovoltaic bracket, first place the positioning shell 4 in the slot of the guide rail 1, place the photovoltaic panel 2 on the guide rail 1, cover the top of the photovoltaic panel 2 with the pressure block 3, align the screw hole in the middle of the pressure block 3 with the transmission cylinder 11, and then insert the bottom transmission rod 13 of the bolt 12 through the screw hole in the middle of the pressure block 3 into the transmission cylinder 11.

[0026] Since the transmission cylinder 11 and transmission rod 13 are structurally matched, pulling the anti-loosening pin 17 upward causes the anti-rotation plate 16 to squeeze the reset spring 15, and then rotating the bolt 12 causes the transmission rod 13 to rotate, which can drive the transmission cylinder 11 and the trapezoidal lead screw 10 to rotate synchronously. Through the lead screw nut 9, the mounting block 2 8 moves upward, and the support arm 7 pushes the clamping arm 6 to rotate around the mounting block 1 5. The clamping arm 6 tightens and clamps the side of the guide rail 1, realizing the fixation of the positioning shell 4 and the guide rail 1. At the same time, the bolt 12 is tightened downward, so that the pressure block 3 presses the edge of the photovoltaic panel 2.

[0027] After tightening, loosen the anti-loosening pin 17, so that the return spring 15 pushes the anti-rotation plate 16 to fit against the top of the pressure block 3. The anti-loosening pin 17 is embedded in the slot 18 on the top of the pressure block 3, which restricts the rotation of the anti-rotation plate 16 and the turntable 14. With the pre-tightening force of the return spring 15, the bolt 12 is prevented from rotating and loosening, which solves the problem of loosening caused by the rotation of traditional fasteners. At the same time, it reduces the offset of the guide rail 1 and improves the installation position accuracy of the photovoltaic panel 2.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
