Description

Technical Field

[0001] This utility model relates to the field of back pressure block technology, specifically a double-bolt back pressure block. Background Technology

[0002] Back pressure blocks for photovoltaic (PV) module installation are common auxiliary tools for fixing PV systems. Currently, different models and sizes of PV modules and corresponding purlins require different models of back pressure blocks. Since the models of PV modules and purlins vary depending on the project, the selection of back pressure blocks must be precise; otherwise, the installation effect will be affected, and the system will have poor adaptability. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a double-bolt back pressure block, which has the advantage of being applicable to purlin assemblies of different thicknesses, thus solving the problem that existing technologies have different back pressure block models depending on the project, resulting in poor adaptability.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A double-bolt back pressure block includes a purlin body as the main body of the device. The purlin body has an external fixing mechanism for adaptably fixing purlin bodies of different sizes. The fixing mechanism has an auxiliary mechanism for further fixing the purlin body. The fixing mechanism includes two pressure plates, with two round rods slidably installed between the two pressure plates. Each of the two round rods has external threads, and each of the two external threads is threaded with a nut. Each of the two pressure plates has two through holes. A fixing block is fixedly connected to the bottom of the lower pressure plate. Multiple springs are installed on both sides of the fixing block. Fixing frames are slidably connected to the two through holes. A fixing component for further fixing the purlin body is provided on the top of the upper pressure plate.

[0006] Preferably, the fixing component includes a connecting block fixedly connected to the top of the pressure plate, a fixing ring fixedly connected to the top of the connecting block, a rotating ring rotatably connected inside the fixing ring, a circular plate fixedly connected to the rotating ring, screws fixedly connected to both sides of the circular plate, and screw rings fixedly connected to both fixing brackets.

[0007] Preferably, the auxiliary mechanism includes a friction plate fixedly connected to one side of the two pressure plates, and a friction block fixedly connected to one side of each of the two fixed frames.

[0008] Preferably, the threads of the two screws are in opposite directions, and the two threaded rings are threadedly connected to the two screws respectively.

[0009] Preferably, one end of a plurality of springs located on both sides of the fixing block is fixedly connected to two fixing frames, and all of the springs are in a stretched state.

[0010] Preferably, the bottoms of both nuts are rotatably connected to the pressure plate.

[0011] By employing the above technical solution, this utility model provides a double-bolt back pressure block, which has at least the following beneficial effects:

[0012] 1. This utility model, by setting a fixing mechanism, enables the device to adaptably fix the main body of the purlin with different thicknesses. By rotating the two nuts, the two pressure plates can be brought closer to each other, thereby adapting to the height of the purlin main body. By rotating the circular plate, the two screws rotate, and the two screws and two threaded rings rotate, so that the two fixing frames can adaptably fix the two sides of the purlin main body, improving the applicability of the device and ensuring the fixing effect of the purlin main body.

[0013] 2. This utility model improves the fixing effect of the device on the main body of the purlin by setting auxiliary mechanisms. The friction between the two pressure plates and the main body of the purlin is increased by the two friction plates, and the friction between the two fixing frames and the main body of the purlin is increased by the two friction blocks, so that different purlin bodies can be effectively fixed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] With different models and sizes of modules and corresponding purlins, different sizes and models of back pressure blocks need to be selected. Currently, the models of modules and purlins in the photovoltaic market vary depending on the project. The selection of back pressure blocks must be precise, otherwise the installation effect will be affected and the adaptability will be poor. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a double-bolt back pressure block.

[0023] Example 1:

[0024] To greatly improve the applicability of the device, combined with Figures 1-4 As shown, a double-bolt back pressure block is proposed. The device body is set with a purlin body 1 as the main body. A fixing mechanism 2 is set on the outside of the purlin body 1. The fixing mechanism 2 is used to adaptively fix the purlin body 1 of different sizes. An auxiliary mechanism 3 is set on the fixing mechanism 2. The auxiliary mechanism 3 is used to further fix the purlin body 1.

[0025] To adaptably fix different purlin bodies 1, a fixing mechanism 2 is proposed. This mechanism consists of two pressure plates 201, with two round rods 202 slidably mounted between them. Each round rod 202 has an external thread 203, and each external thread 203 is threaded with a nut 204. Each pressure plate 201 has two through holes 205. A fixing block 206 is fixedly connected to the bottom of the lower pressure plate 201, and multiple springs 207 are installed on both sides of the fixing block 206. Fixing brackets 209 are slidably connected within each of the two through holes 205. A fixing component 208 for further fixing the purlin body 1 is provided on the top of the upper pressure plate 201. A connecting block 2081 is fixedly connected to the top of the pressure plate 201, and a fixing ring 20 is fixedly connected to the top of the connecting block 2081. 82. A rotating ring 2084 is rotatably connected inside the fixed ring 2082. A circular plate 2083 is fixedly connected to the rotating ring 2084. Screws 2086 are fixedly connected to both sides of the circular plate 2083. Threaded rings 2085 are fixedly connected to both fixed brackets 209. The threads of the two screws 2086 are opposite in direction. By rotating the two nuts 204, the two pressure plates 201 can be brought closer to each other, thus adapting to the height of the purlin body 1. Since the two threaded rings 2085 are threadedly connected to the two screws 2086 respectively, rotating the circular plate 2083 causes the two screws 2086 to rotate, which in turn causes the threads between the two screws 2086 and the two threaded rings 2085 to rotate. This allows the two fixed brackets 209 to adaptively fix both sides of the purlin body 1, improving the applicability of the device and ensuring the fixing effect of the purlin body 1.

[0026] One end of a plurality of springs 207 located on both sides of the fixing block 206 is fixedly connected to two fixing frames 209 respectively. All the springs 207 are in a stretched state. The bottom of the two nuts 204 are rotatably connected to the pressure plate 201, so that the plurality of springs 207 can adapt to the adjustment distance between the two fixing frames 209, so that the main body 1 of the purlin is effectively fixed.

[0027] Example 2:

[0028] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem in the prior art that different sizes of back pressure blocks need to be selected for different models and sizes of components and corresponding purlins, resulting in poor adaptability. However, when fixing the purlin body 1, if the contact surfaces between the two pressure plates 201 and the two fixing brackets 209 and the purlin body 1 are relatively smooth, the fixing effect is poor.

[0029] To further improve the device's fixing effect on the purlin body 1, combined with Figure 1 and Figure 3As shown, an auxiliary mechanism 3 is proposed. Friction plates 301 are fixedly connected to the opposite sides of the two pressure plates 201, and friction blocks 302 are fixedly connected to the opposite sides of the two fixing frames 209. The friction plates 301 increase the friction between the two pressure plates 201 and the main body 1 of the purlin, and the friction blocks 302 increase the friction between the two fixing frames 209 and the main body 1 of the purlin, so that the device can greatly increase the fixing effect of the purlin body 1.
