Description

Technical Field

[0010]

[0001] The utility model relates to the field of photovoltaic modules, and specifically to a self-locking boltless frame and a photovoltaic module. Background Technique

[0002] In the field of photovoltaic panel installation, the traditional frame fixing method mostly uses bolt connection. Although this connection method can provide a relatively stable fixing effect, there are many disadvantages in practical applications.

[0003] Firstly, the installation process is cumbersome. Tools are needed to tighten the bolts one by one, consuming a large amount of time and manpower. Especially in large-scale photovoltaic panel installation, it will significantly increase the installation cost and construction period. Secondly, during long-term use, bolts are easily affected by environmental factors such as rain and moisture, resulting in rust and corrosion, which in turn affects the firmness of the connection and reduces the service life of the frame. Moreover, when rusty bolts need to be disassembled for maintenance or photovoltaic panels need to be replaced, it is difficult to disassemble them, and even may cause damage to the frame, increasing the maintenance difficulty and cost.

[0004] Therefore, it is of great practical significance to develop a frame structure that does not require bolt connection, is convenient for installation and disassembly, and has a good fixing effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self-locking boltless frame and a photovoltaic module to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A self-locking boltless frame includes a frame. A photovoltaic panel is inserted into the frame. Slots are provided on the surface of the frame. Clamping blocks are inserted into the side walls of the slots. An insertion block is inserted into the slots. The insertion block squeezes the clamping blocks to clamp the photovoltaic panel.

[0007] Preferably, a rubber band is fixed in the groove of the frame. The rubber band is in a "U" shape and is clamped between the photovoltaic panel and the groove of the frame.

[0008] Preferably, there are two slots, which are symmetrically distributed about the center of the long side of the frame. Sockets are provided on the side walls of the side plates of the slots. The clamping blocks are inserted into the sockets.

[0009] Preferably, a reserved groove is provided on the inner ring surface of the frame. The reserved groove is connected to the socket. The height of the reserved groove is greater than the height of the socket. An elastic rubber band is fixed between the top surface and the bottom surface of the reserved groove. One end of the clamping block is fixed on the surface of the elastic rubber band.

[0010] Preferably, the other end of the clamping block has an inclined surface on its top surface. When the insert block is inserted into the slot and pushed down, the insert block pushes the clamping block into the slot along the inclined surface. The clamping block stretches the rubber band and deforms, and the rubber band clamps between the photovoltaic panel and the clamping block.

[0011] Preferably, rubber strips are fixed on both parallel sidewalls of the slot, and the rubber strips are clamped between the slot and the insert to produce elastic deformation.

[0012] Preferably, the top surface of the insert block is provided with a scooping groove, and a pull rod is fixed between the two parallel sidewalls of the scooping groove.

[0013] A photovoltaic module including a self-locking boltless frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention proposes a self-locking boltless frame and photovoltaic module. During installation, the photovoltaic panel is simply inserted into the frame groove, where a rubber band clamps it between the panel and the groove for initial fixation. Then, an insert block is inserted, pushing the clamping block to securely hold the photovoltaic panel. The entire installation process requires no tools, is simple to operate, significantly shortens installation time, and improves efficiency, making it particularly suitable for large-scale photovoltaic panel installation projects. When it is necessary to remove the photovoltaic panel, simply squeeze the lever and pull upwards to lift the insert block, causing it to misalign with the clamping block. The rubber band rebounds, pulling the clamping block into the slot, and the panel can be easily removed from the frame. This design makes photovoltaic panel removal extremely convenient, facilitating maintenance, replacement, or cleaning, and reducing maintenance costs and difficulty. Attached Figure Description

It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a self-locking boltless frame, including a frame 1, a photovoltaic panel 2 is inserted into the inside of the frame 1, a rubber band 3 is fixed in the groove of the frame 1, the rubber band 3 is in a "C" shape, and the rubber band 3 is clamped between the photovoltaic panel 2 and the groove of the frame 1. A slot 4 is opened on the surface of the frame 1, a clamping block 7 is inserted into the side wall of the slot 4, and an inserting block 9 is inserted into the slot 4. The inserting block 9 squeezes and pushes the clamping block 7 to clamp the photovoltaic panel 2. When the photovoltaic panel 2 is clamped in the groove of the frame 1 by the clamping block 7, the rubber band 3 is squeezed between the photovoltaic panel 2 and the frame 1, preventing the photovoltaic panel 2 from generating gaps in the frame 1 and causing shaking.

[0024] There are two slots 4, and the two slots 4 are symmetrically distributed about the center of the long side of the frame 1. An insertion port 6 is opened on the side wall of the side plate of the slot 4, and the clamping block 7 is inserted into the insertion port 6; a reserved groove 5 is opened on the inner ring surface of the frame 1, and the reserved groove 5 is communicated with the insertion port 6. The height of the reserved groove 5 is greater than the height of the insertion port 6. An elastic rubber band 8 is fixed between the top surface and the bottom surface of the reserved groove 5, and one end of the clamping block 7 is fixed on the surface of the elastic rubber band 8; the other end of the clamping block 7 has an inclined surface on the top surface. When the insertion block 9 is inserted into the slot 4 and pushed downward, the insertion block 9 squeezes the clamping block 7 into the insertion port 6 along the inclined surface, and the elastic rubber band 8 is stretched and deformed by the clamping block 7, and the elastic rubber band 8 is clamped between the photovoltaic panel 2 and the clamping block 7; Rubber strips 10 are fixed on the two parallel side walls of the slot 4, and the rubber strips 10 are clamped between the slot 4 and the insertion block 9 to generate elastic deformation; a picking groove 11 is opened on the top surface of the insertion block 9, and a pull rod 12 is fixed between the two parallel side walls of the picking groove 11. When it is necessary to disassemble the photovoltaic panel 2, pinch the pull rod 12 with your hand and lift the insertion block 9 upward. After the insertion block 9 and the clamping block 7 are misaligned, the elastic rubber band 8 rebounds and pulls the clamping block 7 to move into the slot 4, and the clamping block 7 no longer clamps the photovoltaic panel 2. The photovoltaic panel 2 can be pulled out of the frame 1.

[0025] Usage method of the self-locking boltless frame: Fix the rubber belt 3 in a "匚" shape in the groove of the frame 1. Insert the photovoltaic panel 2 into the groove of the frame 1. At this time, the rubber belt 3 is clamped between the photovoltaic panel 2 and the groove of the frame 1, playing a role in preliminary fixation and preventing shaking. There are two slots 4 symmetrically distributed about the center of the long side on the surface of the frame 1. An insertion opening 6 is provided on the side wall of the side plate of the slot 4. A reserved groove 5 communicating with the insertion opening 6 and having a height greater than the insertion opening 6 is provided on the inner ring surface of the frame 1. An rubber belt 8 is fixed between the top surface and the bottom surface of the reserved groove 5. Fix one end of the clamping block 7 on the surface of the rubber belt 8 and insert the other end into the insertion opening 6. Rubber strips 10 are fixed on both of the two parallel side walls of the slot 4. Insert the insertion block 9 into the slot 4. During the insertion process, the rubber strips 10 are clamped between the slot 4 and the insertion block 9 and generate elastic deformation, playing a role in buffering and increasing friction. Continue to push down the insertion block 9. The insertion block 9 squeezes the clamping block 7 into the insertion opening 6 along the inclined surface of the top surface of the other end of the clamping block 7. At this time, the rubber belt 8 is tensioned and deformed, and the rubber belt 8 is clamped between the photovoltaic panel 2 and the clamping block 7. At the same time, the clamping block 7 squeezes the photovoltaic panel 2, so that the photovoltaic panel 2 is firmly clamped in the groove of the frame 1 to complete the installation. When disassembling the photovoltaic panel: A picking groove 11 is provided on the top surface of the insertion block 9. A pull rod 12 is fixed between the two parallel side walls of the picking groove 11. Pinch the pull rod 12 and lift the insertion block 9 upward. When the insertion block 9 and the clamping block 7 are misaligned, the rubber belt 8 rebounds and pulls the clamping block 7 to move into the slot 4, and the clamping block 7 no longer generates a clamping force on the photovoltaic panel 2. Pull the photovoltaic panel 2 out of the frame 1 to complete the disassembly.
