Description

Technical Field

[0001] This application relates to the field of photovoltaic bracket accessories, and in particular to angle clamps. Background Technology

[0002] Color steel roofing supports are made of color-coated steel sheets, which are roll-formed into various corrugated shapes. They are suitable for roofs, walls, and interior and exterior wall decorations of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. They are lightweight, high-strength, rich in color, easy and quick to construct, earthquake-resistant, fireproof, rainproof, long-lasting, and maintenance-free, and are now widely used. Fixtures are devices used in the mechanical manufacturing process to fix the workpiece in the correct position for construction or inspection.

[0003] When installing photovoltaic panels, on some irregularly shaped walls, angle clamps are needed to fix them to the top of the wall, and then the guide rail is fixed to the top of the angle clamp. Although the existing angle clamps can adjust the clamping distance to a certain extent, they do not have the function of angle adjustment. This can easily lead to unstable clamping when the angle of the irregularly shaped wall changes. At the same time, the existing angle clamps are usually fixed in size, and the height of the top used to fix the guide rail after installation is also fixed. When there is a height difference or installation deviation, a large number of shims are needed to support the guide rail. Utility Model Content

[0004] To address the issue of the lack of height fixation function at the top of the installation unit for fixing the guide rail after installation, which does not have angle adjustment capabilities, this application provides an angle clamp.

[0005] The angle clamp provided in this application adopts the following technical solution: it includes a first clamping plate and a second clamping plate. The top of the first clamping plate near the second clamping plate has an arc-shaped groove. One end of the second clamping plate is located inside the arc-shaped groove. Both ends of the arc-shaped groove at the top of the first clamping plate are fixed with connecting plates. A connecting shaft is fixed through the middle of the two connecting plates. One end of the second clamping plate is rotatably connected to the arc-shaped groove. One end of the connecting shaft is threaded with a first nut. A third bolt is rotatably connected to the top of the inner wall of the second clamping plate. A pressing block is threaded onto the outer wall of the third bolt. A through hole is opened through one side of both the first clamping plate and the second clamping plate. A second limiting bolt is threaded through the through hole. One end of the second limiting bolt is threaded with a second nut.

[0006] By adopting the above technical solution, the bottom of the first clamping plate and the second clamping plate are restricted by using the second nut and the second limiting bolt, thereby controlling the spacing value of the second nut and the second limiting bolt.

[0007] Preferably, both sides of the extrusion block are inclined, and both sides of the extrusion block are close to the opposite side of the first clamping plate and the second clamping plate, respectively.

[0008] By adopting the above technical solution, by rotating the third bolt, the extrusion block is limited by the first clamping plate and the second clamping plate and will not rotate together, thereby causing the extrusion block to move vertically up and down. The inclined sides change the distance between the middle of the clamping plate and the second clamping plate, thereby adjusting the angle between the first clamping plate and the second clamping plate.

[0009] Preferably, the length of the through hole is greater than the diameter of the second limiting bolt, and there are two second limiting bolts, which are located on both sides of the third bolt.

[0010] By adopting the above technical solution, when the angle between the first clamping plate and the second clamping plate changes, the second limiting bolt can slide in the through hole, and the larger through hole will not affect the change of the angle between the first clamping plate and the second clamping plate.

[0011] Preferably, the first clamping plate and the second clamping plate each have a groove on their opposite sides, and there are multiple grooves arranged at equal intervals.

[0012] By adopting the above technical solution, the friction between the first and second clamping plates and the top wall is increased by setting multiple grooves, making the angled installation more secure.

[0013] Preferably, a sleeve plate is fixed to the top of the first clamping plate on the side away from the second clamping plate, and a lifting plate is movably sleeved on the top of the sleeve plate.

[0014] By adopting the above technical solution, the horizontal height of the top mounting plate can be adjusted by moving the sleeve plate inside the lifting plate.

[0015] Preferably, a mounting plate is fixed to the top of the lifting plate, and a connecting hole is formed through the middle of the top of the mounting plate.

[0016] By adopting the above technical solution, the mounting plate is adjusted to the same height as the track to be installed, and the track can be quickly connected to the mounting plate through the connection holes.

[0017] Preferably, both sides of the middle part of one side of the sleeve plate are threadedly connected with first limiting bolts, and one end of the first limiting bolt is attached to the lifting plate.

[0018] By adopting the above technical solution, after the horizontal height of the mounting plate is adjusted, the first limiting bolt is rotated to make the first limiting bolt fit tightly with the lifting plate, thereby limiting the lifting plate and providing limiting support for the mounting plate.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application uses the third bolt to rotate the extrusion block vertically up and down, and the inclined sides change the distance between the middle of the clamping plate and the second clamping plate, thereby adjusting the angle between the first clamping plate and the second clamping plate. At this time, the second limiting bolt slides in the through hole. Then, the first clamping plate and the second clamping plate are placed on the roof to be installed. Subsequently, the second limiting bolt and the second nut are tightened, thereby achieving the effect of quickly adjusting the angle between the two clamping plates of the angle clamp, making the subsequent installation more stable.

[0021] 2. This application adjusts the horizontal height of the top mounting plate by moving the sleeve plate inside the lifting plate, adjusting the mounting plate to the same height as the track to be installed. The track can be quickly connected to the mounting plate through the opening connection hole. By rotating the first limit bolt, the first limit bolt is tightly fitted with the lifting plate, limiting the lifting plate, thereby limiting and supporting the mounting plate. This achieves the effect of quickly adjusting the horizontal height of the support position, making subsequent guide rail installation more convenient. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses an angle clamp, including a first clamping plate 1 and a second clamping plate 2. The first clamping plate 1 has an arc-shaped groove 7 at its top near the second clamping plate 2. One end of the second clamping plate 2 is located inside the arc-shaped groove 7. Connecting plates 12 are fixed to both ends of the arc-shaped groove 7 at the top of the first clamping plate 1. A connecting shaft 11 is fixedly inserted through the middle of the two connecting plates 12. One end of the second clamping plate 2 is rotatably connected to the arc-shaped groove 7. A first nut 13 is threaded onto one end of the connecting shaft 11. A third bolt 15 is rotatably connected to the top of the inner wall of the second clamping plate 2. The outer wall of the third bolt 15... A pressing block 16 is threaded onto a clamping device. By adjusting the position of the pressing block 16, the distance between the middle parts of the first clamping plate 1 and the second clamping plate 2 can be adjusted, thereby adjusting the included angle between the first clamping plate 1 and the second clamping plate 2. A through hole 8 is provided on one side of both the first clamping plate 1 and the second clamping plate 2. A second limiting bolt 9 is threaded onto the through hole 8. A second nut 10 is threaded onto one end of the second limiting bolt 9. By using the second nut 10 and the second limiting bolt 9, the bottom of the first clamping plate 1 and the second clamping plate 2 are restricted, thereby controlling the distance between the second nut 10 and the second limiting bolt 9.

[0029] Reference Appendix Figure 3 The extrusion block 16 is inclined on both sides, and the two sides of the extrusion block 16 are close to the opposite side of the first clamping plate 1 and the second clamping plate 2, respectively. By rotating the third bolt 15, the extrusion block 16 is limited by the first clamping plate 1 and the second clamping plate 2 and will not rotate together, so that the extrusion block 16 moves vertically up and down. The inclined sides change the distance between the middle of the clamping plate 1 and the second clamping plate 2, thereby adjusting the angle between the first clamping plate 1 and the second clamping plate 2.

[0030] Reference Appendix Figure 1 The length of the through hole 8 is greater than the diameter of the second limiting bolt 9, and there are two second limiting bolts 9. The two second limiting bolts 9 are located on both sides of the third bolt 15. When the angle between the first clamping plate 1 and the second clamping plate 2 changes, the second limiting bolt 9 can slide in the through hole 8. The larger through hole 8 will not affect the change of the angle between the first clamping plate 1 and the second clamping plate 2.

[0031] Reference Appendix Figure 1 The first clamping plate 1 and the second clamping plate 2 each have a groove 14 on their opposite sides. There are multiple grooves 14, which are arranged at equal intervals. The multiple grooves 14 increase the friction between the first clamping plate 1 and the second clamping plate 2 and the wall top, making the angled installation more secure.

[0032] Reference Appendix Figure 2 The top of the first clamping plate 1 is fixed with a sleeve plate 3 on the side away from the second clamping plate 2. The top of the sleeve plate 3 is movably sleeved with a lifting plate 4. The horizontal height of the top mounting plate 5 can be adjusted by moving the sleeve plate 3 inside the lifting plate 4.

[0033] Reference Appendix Figure 2 The top of the lifting plate 4 is fixed with a mounting plate 5. A connecting hole 51 is opened through the middle of the top of the mounting plate 5. The mounting plate 5 is adjusted to the same height as the track to be installed. The track can be quickly connected to the mounting plate 5 through the connecting hole 51.

[0034] Reference Appendix Figure 2 Both sides of the middle part of one side of the sleeve plate 3 are threaded with first limiting bolts 6. One end of the first limiting bolt 6 is attached to the lifting plate 4. After the horizontal height of the mounting plate 5 is adjusted, the first limiting bolt 6 is rotated to make the first limiting bolt 6 and the lifting plate 4 fit tightly together, thereby limiting the lifting plate 4 and providing limiting support for the mounting plate 5.

[0035] The implementation principle of the angle clamp in this embodiment is as follows: First, adjust the angle between the first clamping plate 1 and the second clamping plate 2 according to the angle of the installation on the roof. By rotating the third bolt 15, the pressing block 16 is limited by the first clamping plate 1 and the second clamping plate 2 and will not rotate together, thereby causing the pressing block 16 to move vertically up and down. The inclined sides change the distance between the middle of the clamping plates 1 and 2, thereby adjusting the angle between the first clamping plate 1 and the second clamping plate 2. When the angle between the first clamping plate 1 and the second clamping plate 2 changes, the second limiting bolt 9 can slide in the through hole 8. The larger through hole 8 will not affect the change of the angle between the first clamping plate 1 and the second clamping plate 2. Then, the first clamping plate 1. Place the first clamping plate 1 and the second clamping plate 2 on the roof to be installed. Then tighten the second limiting bolt 9 and the second nut 10. The first clamping plate 1 and the second clamping plate 2 fit against the roof. The multiple grooves 14 increase the friction between the first clamping plate 1 and the second clamping plate 2 and the roof, making the angled installation more secure. Then move the sleeve plate 3 inside the lifting plate 4 to adjust the horizontal height of the top mounting plate 5. Adjust the mounting plate 5 to the same height as the track to be installed. The track can be quickly connected to the mounting plate 5 through the opening connection hole 51. By rotating the first limiting bolt 6, the first limiting bolt 6 fits tightly against the lifting plate 4, limiting the lifting plate 4, thereby limiting and supporting the mounting plate 5.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
