Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic accessories, and particularly relates to a pressing tool for photovoltaic modules. Background Art

[0002] Whether in a household photovoltaic system or an industrial and commercial photovoltaic system, photovoltaic modules are an indispensable part of the photovoltaic system. At present, the most common fixing method for photovoltaic modules is mechanical fastening, which fixes the pressing block through bolts and presses the photovoltaic module to fix it. In the photovoltaic industry, the application of pressing blocks has been very mature and has become a standard product in the industry. The pressing blocks are used to ensure the connection between photovoltaic modules and can also be connected to the guide rails, forming a stable whole between photovoltaic modules, preventing the bracket from shifting and sliding, and ensuring the smooth installation of the modules.

[0003] In the prior art, when installing the pressing block, usually two photovoltaic modules are placed on a U-shaped bracket, then the pressing block is placed in the middle of the two photovoltaic modules, and then the bolt is passed through the plastic wing nut, and the plastic wing nut passes through the middle of the pressing block. Then the plastic wing nut is rotated 90 degrees so that the plastic wing nut is stuck in the U-shaped bracket. Finally, the bolt is tightened to complete the installation of the pressing block and the fixing of the photovoltaic module. This fixing method is not firm enough, and there is still a risk of sliding of the photovoltaic module after fixing, and the photovoltaic module cannot be positioned. During installation, the position of the photovoltaic module needs to be adjusted frequently until the two photovoltaic panels are completely aligned. In addition, when installing the existing pressing block, the plastic wing nut needs to be rotated manually and then the bolt is tightened. The plastic wing nut needs to be rotated in place to tighten the bolt. There are several pressing devices on one photovoltaic module, and the above installation method needs to be repeated several times for each installed photovoltaic module, which is troublesome to disassemble and assemble and has low work efficiency.

[0004] In order to solve the deficiencies of the prior art, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a medium pressing block for photovoltaic with a locking structure [CN 202321416221.8], which includes a feeding mechanism, a screw locking mechanism and a suction nozzle for sucking screws. The feeding mechanism includes a U-shaped pressing plate, photovoltaic modules are arranged on both sides of the U-shaped pressing plate, and pressing plates abutted against the upper surfaces of the photovoltaic modules are arranged along the upper edges of both side walls of the U-shaped pressing plate. A bolt hole is formed in the middle of the bottom of the U-shaped pressing plate, and a fastening bolt passes through the bolt hole; there are two connecting plates, and the connecting plates are symmetrically arranged in the U-shaped pressing plate on both sides of the fastening bolt.

[0005] The above solution solves to a certain extent the problems that the fixing method of the photovoltaic fixing pressing block in the prior art is not firm enough and the position needs to be adjusted frequently during installation, but there are still many deficiencies in this solution. For example, the manual operation method is troublesome to disassemble and assemble, has a large labor intensity and low work efficiency. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0025] As Figures 1-5 shown, a pressing tooling for photovoltaic modules includes a connecting guide rail 2 which is arranged at the bottom of the photovoltaic module 1 and is concave-shaped, and the upper end of the connecting guide rail 2 has an insertion gap 21. A pressing block structure 3 which is U-shaped is inserted at the upper end of the connecting guide rail 2. A support block assembly 4 which is symmetrically arranged and is located in the gap between two photovoltaic modules 1 is clamped on the inner wall of the pressing block structure 3, and the upper ends of the support block assemblies 4 are connected by a fixed block mechanism 5. The fixed block mechanism 5 is connected to the pressing block structure 3 through a bolt 6 and presses on the upper end surfaces of the two photovoltaic modules 1.

[0026] Among them, the pressing block structure 3 includes a connecting base 31. At both ends of the connecting base 31, there are pressing parts 32 arranged along the height direction of the connecting guide rail 2. And at the upper end of the pressing part 32, there is a pressing hook part 33 that presses tightly on the upper end surface of the connecting guide rail 2. And near the end of the pressing part 32 connected to the connecting base 31, there is a through support block limiting through groove 34.

[0027] The setting of the pressing block structure 3 is mainly used for inserting and positioning the bottom of the support block main body 41, and cooperating with the connecting guide rail 2 to lock the base, so as to ensure the fastening state.

[0028] Visibly, the outer wall of the pressing part 32 contacts the inner wall of the insertion gap 21 of the connecting guide rail 2, and the connecting base 31, the pressing part 32, and the pressing hook part 33 are integrally formed.

[0029] The integrally formed structure has better stability and improves the bearing performance. And here, the pressing block structure 3 is positioned in the insertion gap 21 through the pressing hook part 33 and the limiting part 42 at the bottom of the support block main body 41.

[0030] Obviously, the connecting base 31 is provided with a threaded hole 35 for the bolt 6 to connect.

[0031] Furthermore, the support block assembly 4 includes a support block main body 41 arranged along the height direction of the connecting guide rail 2. At the lower end of the support block main body 41, there is a limiting part 42 for being stuck into the support block limiting through groove 34. And inside the connecting guide rail 2, there is a positioning part 43 for positioning the limiting part 42. After the limiting part 42 is stuck into the limiting through groove 34, the limiting part 42 extends to the outside of the pressing part 32 and abuts against the positioning part 43.

[0032] Embodiment 1

[0033] At the upper end of the support block main body 41, there is an insertion and positioning through hole 44, and there are several top pressure springs 45 between the support block main bodies 41.

[0034] The top pressure spring 45 is used to press the support block main body 41 against the inner wall of the pressing part 32 to further press and position the pressing block structure 3.

[0035] Among them, the fixed block mechanism 5 includes a fixed block main body 51. On the fixed block main body 51, there is a bolt through hole 52 for the bolt 6 to pass through, and on both sides of the bolt through hole 52, there are support block insertion holes 53 for the support block main body 41 to insert into.

[0036] Specifically, at both ends of the support block insertion hole 53, there are support block movable holes 54, and the support block movable holes 54 are communicated with the support block insertion holes 53.

[0037] Specifically, a positioning insertion plate 55 corresponding to the insertion positioning through hole 44 is formed inside the support block moving hole 54 and the support block insertion hole 53.

[0038] During use, the support block main body 41 can move away from or close to the connecting guide rail 2 along the support block moving hole 54, facilitating the operation of pressing the photovoltaic module 1.

[0039] Preferably, a pressing gap 56 for inserting the frame of the photovoltaic module 1 is formed between the bottom of the fixing block main body 51 and the connecting guide rail 2.

[0040] In this embodiment, the positioning insertion plate 55 is inserted into the positioning through hole 44, and the upper and lower parts of the two support block main bodies 41 move towards or away from each other synchronously. The sizes of the positioning insertion plate 55 and the positioning through hole 44 are matched to guide the horizontal movement of the two support block main bodies 41. At the same time, the fixing block main body 51 moves up and down relative to the support block main body 41, providing a guiding function during the movement process.

[0041] Embodiment 2

[0042] In this embodiment, the insertion positioning through hole 44 is not provided at the upper end of the support block main body 41, and the support block moving holes 54 are not provided at both ends of the support block insertion hole 53.

[0043] In this embodiment, the lower parts of the two support block main bodies move towards or away from each other.

[0044] In summary, the principle of this embodiment is that this pressing tooling is a pre-assembled part. The limiting parts 42 of the two support block assemblies are inserted into the positioning parts 43. The upper end of the support block main body 41 is matched with the support block moving hole 54 of the fixing block mechanism 5. The bolt 6 is inserted into the bolt through hole 52 of the fixing block mechanism 5 and threadedly matched with the threaded hole 35 of the pressing block structure 3 to realize the assembly of the pressing tooling.

[0045] During use, pinch the two support block bodies 41 by hand. The pressing spring 45 between the two support block bodies 41 is compressed under the action of an external force, and the distance between the two support block bodies 41 decreases. At this time, the width of the pressing block structure 3 is not greater than the width of the insertion gap 21, which facilitates the pressing block structure 3 to be conveniently placed into the insertion gap 21 of the connecting guide rail 2 along the height direction of the connecting guide rail 2. When the placement is in place, that is, the lower surface of the pressing hook portion 33 is in contact with the upper surface of the connecting guide rail 2. Release the support block body 41 to relieve the force. Due to the pressing force of the pressing spring 45, the limiting portion 42 passes through the limiting through groove 34, and the upper surface of the limiting portion 42 just abuts against the bottom end surface of the positioning portion 43. In the height direction of the connecting guide rail 2, the hook portion 33 and the limiting portion 42 form a locking structure locked at the positioning portion 43, quickly fixing this pressing tool on the connecting guide rail 2. Place the frame of the photovoltaic module 1 on the connecting guide rail 2, and the side of the fixed block body 51 presses the upper part of the frame, and lock the bolt 6, so as to press the photovoltaic module 1 by using the fixed block body 51.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0047] Although terms such as photovoltaic module 1, connecting guide rail 2, insertion gap 21, pressing block structure 3, connecting base 31, pressing portion 32, pressing hook portion 33, support block limiting through groove 34, threaded hole 35, support block assembly 4, support block body 41, limiting portion 42, positioning portion 43, insertion positioning through hole 44, pressing spring 45, fixed block mechanism 5, fixed block body 51, bolt through hole 52, support block insertion hole 53, support block moving hole 54, positioning insertion plate 55, pressing gap 56, bolt 6 are used more in this article, the possibility of using other terms is not excluded.
