[0002] Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are generally made of aluminum alloy, carbon steel and stainless steel. The photovoltaic brackets in the photovoltaic power station are fixed to the roof through a safe and reliable base. As the base of the photovoltaic bracket and the roof installation node, the existing photovoltaic bracket bases have various installation forms, such as direct perforation connection on the corrugated steel plate, fixation with self-tapping screws, connection through rivet nuts on the steel plate, and direct hot-melt welding on the polymer waterproof membrane layer without rooting to the corrugated steel plate, etc.

[0003] In the prior art, the connection base of the photovoltaic bracket is usually a concrete block, which improves the stability of the photovoltaic bracket by bolts and its own weight. It is usually cast and fixed to the bracket, making it inconvenient to remove the bracket from the connection base, reducing the practicality of the connection base and increasing the difficulty of repairing the photovoltaic bracket when it is damaged.

[0004] Therefore, a universal photovoltaic bracket connection base is needed to solve the problem in the prior art that the photovoltaic bracket and the connection base are usually integrated and inconvenient to disassemble. Utility Model Content

[0005] The purpose of the present invention is to provide a universal photovoltaic bracket connection base to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a universal photovoltaic bracket connection base, comprising a base body, a connecting mechanism is provided inside the base body, and an adjustment mechanism is provided between two groups of the base bodies;

[0007] The adjusting mechanism includes connecting rods, which are respectively fixed to the front and rear parts of the two groups of base bodies close to one side wall, and the middle parts of the connecting rods on the left and right sides close to the one side wall are provided with sliding grooves, and the inner sides of the sliding grooves are penetrated and slidably connected with adjusting rods, and an active cavity is provided inside the adjusting rod, and the middle of the active cavity is rotatably connected with a bidirectional screw, and the upper and lower parts of the outer periphery of the bidirectional screw are threadedly connected with threaded blocks, and connecting plates are fixed on the left and right sides of the threaded block, and a limiting block is fixed on the end of the connecting plate away from the threaded block.

[0008] It should be noted in the solution that the connecting mechanism includes connecting grooves, which are respectively arranged on the front and rear sides of the top wall of the base body, and the inner sides of the connecting grooves are slidably connected to the bracket rods.

[0009] It is worth mentioning that a fastening screw is threadedly connected to the middle of the side wall of the connecting groove away from the connecting rod, and the other end of the fastening screw is located inside the connecting groove.

[0010] It should be further explained that the limit blocks are all passed through and slidably connected to the inner side of the through holes, and the through holes are respectively arranged on the left and right sides of the middle part of the upper and lower walls of the active cavity.

[0011] As a preferred embodiment, a plurality of evenly distributed limiting holes are provided in the middle of the upper and lower walls of the connecting rod, and the limiting holes are clearance-matched with the limiting blocks.

[0012] As a preferred embodiment, the middle portion of the top wall of the adjusting rod is rotatably connected to a knob, and the knob is fixed to the bidirectional screw.

[0013] Compared with the prior art, the universal photovoltaic bracket connection base provided by the present invention has at least the following beneficial effects:

[0014] (1) By inserting the bracket rod into the connecting groove on the top of the base body, and then rotating the fastening screw on the outside of the base body, the fastening screw moves toward the inside of the connecting groove during the rotation process, so that the bracket rod can be clamped and fixed with the inner wall of the connecting groove, thereby realizing the connection between the connecting base and the bracket, which reduces the maintenance difficulty of the photovoltaic bracket compared with the traditional integrated connecting base.

[0015] (2) When the distance between the two groups of base bodies needs to be adjusted, the knob is turned, and the two-way screw is driven to rotate during the rotation of the knob. During the rotation of the two-way screw, the upper and lower threaded blocks are moved closer to each other, so that the limit block is retracted into the movable cavity. After sliding the connecting rods on both sides to adjust the distance between the base bodies, the knob is turned again to make the two groups of threaded blocks move away from each other and the limit block is inserted into the limit hole. The adjustment of the distance between the base bodies is completed, so that it can adapt to photovoltaic brackets of different sizes, thereby improving the practicality of connecting the base.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] See also Figure 1-3 The utility model provides a universal photovoltaic bracket connection base, including a base body 1, a connecting mechanism 2 is provided inside the base body 1, and an adjustment mechanism 3 is provided between two groups of base bodies 1;

[0022] The adjustment mechanism 3 includes a connecting rod 7, and a slide groove 10 is provided inside the connecting rod 7. By making the adjusting rod 8 slide inside the slide groove 10, the distance between the two groups of connecting rods 7 is controlled, thereby controlling the spacing of the base body 1. The connecting rods 7 are respectively fixed to the front and rear parts of the two groups of base bodies 1 close to one side wall. The left and right connecting rods 7 are close to the middle part of the side wall. The inner side of the slide groove 10 is penetrated and slidably connected with the adjusting rod 8. The slide groove 10 provides space for the adjusting rod 8 to slide. The adjusting rod 8 is provided with an active cavity 13 inside. The active cavity 13 is provided with a plurality of movable cavities. 3 are rotatably connected with a bidirectional screw 14 in the middle. During the rotation of the bidirectional screw 14, the upper and lower sets of threaded blocks 15 are driven to move closer to or away from each other. The upper and lower parts of the outer periphery of the bidirectional screw 14 are threadedly connected with threaded blocks 15. Connecting plates 16 are fixed on the left and right sides of the threaded blocks 15. During the up and down movement of the threaded blocks 15, the limit blocks 11 are driven to move up and down through the connecting plates 16, so that the limit blocks 11 can be retracted into the inside of the active cavity 13 or inserted into the inside of the through hole 17. The limit blocks 11 are fixed on the ends of the connecting plates 16 away from the threaded blocks 15.

[0023] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the connecting mechanism 2 includes a connecting groove 4, which is respectively arranged on the front and rear sides of the top wall of the base body 1. The inner side of the connecting groove 4 is slidably connected with a bracket rod 6. The bracket rod 6 is part of the photovoltaic bracket and plays a role in supporting the photovoltaic bracket.

[0024] Further as Figure 3 As shown, it is worth mentioning that a fastening screw 5 is threadedly connected to the middle part of the side wall of the connecting groove 4 away from the connecting rod 7, and the other end of the fastening screw 5 is located on the inner side of the connecting groove 4. The fastening screw 5 cooperates with the connecting groove 4 to fix the bracket rod 6 on the inner side of the connecting groove 4.

[0025] This solution has the following working process: when it is necessary to connect the photovoltaic bracket and the connecting base, first turn the knob 12. During the rotation of the knob 12, the bidirectional screw 14 is driven to rotate. During the rotation of the bidirectional screw 14, the upper and lower threaded blocks 15 are brought closer to each other, so that the limit block 11 is retracted into the active cavity 13. After sliding the connecting rods 7 on both sides to adjust the spacing of the base body 1, turn the knob 12 again to make the two sets of threaded blocks 15 move away from each other while inserting the limit block 11 into the limit hole 9, completing the spacing adjustment of the base body 1 so that it can adapt to photovoltaic brackets of different sizes. Then, insert the bracket rod 6 into the connecting groove 4 at the top of the base body 1, and rotate the fastening screw 5 on the outside of the base body 1 so that the fastening screw 5 moves toward the inside of the connecting groove 4 during rotation, so that it can cooperate with the inner wall of the connecting groove 4 to clamp and fix the bracket rod 6, thereby realizing the connection between the connecting base and the bracket.

[0026] According to the above working process, it can be seen that: with the cooperation of the base body 1, connecting rod 7, adjusting rod 8, limiting hole 9, slide groove 10, limiting block 11, knob 12, movable cavity 13, threaded block 15, connecting plate 16 and bidirectional screw 14, the spacing between the two groups of base bodies 1 can be adjusted to adapt to the connection of photovoltaic brackets of different widths, thereby improving the practicality of the connecting base.

[0027] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the limit blocks 11 are all passed through and slidably connected to the inner side of the through holes 17, and the through holes 17 are respectively arranged on the left and right sides of the middle part of the upper and lower walls of the movable cavity 13. The limit blocks 11 are inserted into the inner side of the through holes 17 and inserted into the interior of the limit holes 9 at the same time, so that the connecting rod 7 and the adjusting rod 8 can be fixed.

[0028] Further as Figure 1 As shown, it is worth mentioning that a plurality of evenly distributed limiting holes 9 are provided in the middle of the upper and lower walls of the connecting rod 7. The limiting holes 9 are clearance-matched with the limiting blocks 11, and the limiting blocks 11 can be inserted into or pulled out from the limiting holes 9.

[0029] Further as Figure 1 As shown, it is worth mentioning that the middle part of the top wall of the adjusting rod 8 is rotatably connected with a knob 12, and the knob 12 is fixed to the bidirectional screw 14. Rotating the knob 12 can make the bidirectional screw 14 rotate synchronously, thereby driving the two sets of threaded blocks 15 to move closer to or away from each other.

[0030] In summary: the limit block 11 is inserted into the inner side of the through hole 17 and the inner side of the limit hole 9 at the same time, so that the connecting rod 7 and the adjusting rod 8 can be fixed, and the limit block 11 can be inserted into or pulled out from the inner side of the limit hole 9. Turning the knob 12 can make the bidirectional screw 14 rotate synchronously, so that the two sets of threaded blocks 15 can be driven to approach or move away from each other. After sliding the connecting rods 7 on both sides to adjust the spacing of the base body 1, turn the knob 12 again to make the two sets of threaded blocks 15 move away from each other and insert the limit block 11 into the inner side of the limit hole 9 to complete the spacing adjustment of the base body 1 so that it can adapt to photovoltaic brackets of different sizes. Insert the bracket rod 6 into the connecting groove 4 at the top of the base body 1, rotate the fastening screw 5 on the outside of the base body 1, so that the fastening screw 5 moves toward the inner side of the connecting groove 4 during rotation, so that it can cooperate with the inner wall of the connecting groove 4 to clamp and fix the bracket rod 6, thereby realizing the connection between the connecting base and the bracket.
