Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panels, and in particular relates to a photovoltaic panel connecting fastener for installing photovoltaic panels for building construction. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). When installing the photovoltaic panel on a bracket, fasteners may be required to connect the photovoltaic panel and the bracket. Therefore, it can be seen that existing photovoltaic panels basically meet people's practical needs, but the following problems still exist.

[0003] When the operator installs the connecting fastener on the mounting plate, the operator may need to hold the connecting fastener to fit the connecting fastener and the mounting plate together, and then the operator installs the connecting fastener on the mounting plate through the cumbersome installation of the bolt thread after threading the mounting plate. However, when general connecting fasteners are installed on the plate, the operator may need to support the connecting fastener to prevent the connecting fastener from sliding back and forth on the mounting plate, which may make the installation of the connecting fastener more cumbersome for the operator. For this reason, we propose a photovoltaic panel connecting fastener for installing photovoltaic panels in building construction. Utility Model Content

[0004] The utility model provides a photovoltaic panel connecting fastener for installing photovoltaic panels in building construction. After the connecting fastener body and the mounting plate are fitted together, the clamping plate is clamped on the surface of the mounting plate, and the connecting fastener body is pre-installed on the mounting plate, so as to prevent the connecting fastener body from sliding randomly on the surface of the mounting plate, thereby improving the convenience of installation for the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovoltaic panel connecting fastener for installing photovoltaic panels in building construction, including a connecting fastener body, an avoidance groove is opened in the middle of the connecting fastener body, and a plurality of groups of spring grooves are fixed to the ends of both sides of the avoidance groove, a pull rod passes through the middle of the spring groove, and a spring is wrapped around the surface of the pull rod, and the ends of both sides of the spring are respectively abutted between the inner wall of the spring groove and the surface of the pressure plate, the pressure plates are fixed on the pull rod, and the ends of the pull rod are fixed with a splint attached to the surface of the connecting fastener body, and an anti-sliding block is fixed to one side where the splint and the connecting fastener body are attached to each other.

[0006] Furthermore, a connecting block is provided in the middle of the avoidance groove, and the connecting block is slidably connected to the avoidance groove, and second abutment plates matching the number of spring grooves are symmetrically fixed at the two side ends of the avoidance groove, and the end of the second abutment plate is fitted with a first abutment plate fixed on the end of the pull rod, and a pull plate is fixed at the end of the connecting block.

[0007] Furthermore, a fixing plate fixed on the inner wall of the avoidance groove is symmetrically attached to the surface of the connection block, and a traction block is fixed on one side where the fixing plate and the connection block are attached to each other, and a traction groove opened on the connection block is sleeved on the surface of the traction block.

[0008] Furthermore, the second abutment plate and the first abutment plate are both configured to have an inclined slope, and the inclined slope surfaces of the first abutment plate and the second abutment plate are configured to fit each other.

[0009] Furthermore, waist-shaped holes matching each other in shape are provided in the middle of the avoidance groove, the connection block and the connecting fastener body.

[0010] Furthermore, the anti-sliding block is provided with a plurality of groups of semicircular protrusions on one side close to the surface of the connecting fastener body.

[0011] The beneficial effects of the utility model are:

[0012] 1. The connecting fastener of the photovoltaic panel is provided with a clamping plate, a spring groove, a pulling rod and a pressure plate. After the operator pulls the clamping plate to move, the clamping plate drives the pressure plate to move through the pulling rod, so that the pressure plate squeezes the spring groove, and the spring groove undergoes elastic deformation. After the two sets of clamping plates are moved out from both sides of the connecting fastener body, the operator places the connecting fastener body on the mounting plate. Then the operator releases the clamping plate, and after the clamping plate no longer squeezes the spring groove through the pressure plate, the elastic deformation of the spring groove is restored, and the spring groove pushes the pulling rod to move through the pressure plate, so that the pulling rod pushes the clamping plate to move, and the clamping plate is clamped on the surface of the mounting plate, which is convenient for the operator to pre-install the connecting fastener body on the mounting plate, thereby improving the convenience of the operator in installing the connecting fastener body.

[0013] 2. The connecting fasteners of the photovoltaic panel are provided with a connecting block, a second abutment plate and a first abutment plate. After the operator pulls the pulling plate to move, the pulling plate drives the connecting block to move, and the connecting block pushes the first abutment plate to move through the second abutment plate, and the first abutment plate pushes the clamping plate to move through the pull rod, so that the operator can pull two sets of clamping plates to move at one time, thereby improving the stability of the operator pulling the two sets of clamping plates to move.

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] Example:

[0023] See also Figure 1 - Figure 5 A photovoltaic panel connecting fastener for installing photovoltaic panels in building construction includes a connecting fastener body 1, an avoidance groove 15 is opened in the middle of the connecting fastener body 1, and a plurality of groups of spring grooves 4 are fixed to the ends of both sides of the avoidance groove 15, a pull rod 5 is passed through the middle of the spring groove 4, and a spring 6 is wound on the surface of the pull rod 5, and the ends of both sides of the spring 6 are respectively abutted between the inner wall of the spring groove 4 and the surface of the pressure plate 7, and the pressure plates 7 are fixed on the pull rod 5, and the ends of the pull rod 5 are fixed with a clamping plate 3 attached to the surface of the connecting fastener body 1, and the clamping plate 3 and the connecting fastener body 1 are attached to each other. On one side, an anti-sliding block 2 is fixed. When the operator installs the connecting fastener body 1 on the mounting plate installed on the photovoltaic panel, the operator first pulls the clamping plate 3, and the clamping plate 3 drives the pull rod 5 to move, and when the pull rod 5 moves, the pull rod 5 drives the pressure plate 7 to move in the spring groove 4, and the pressure plate 7 moves in the spring groove 4. When moving in the groove 4, the pressure plate 7 squeezes the spring 6, causing the spring 6 to undergo elastic deformation. The spring 6 avoids the pressure plate 7, causing the pull rod 5 to move out of the spring groove 4, and the clamping plate 3 is moved away from both sides of the connecting fastener body 1. Then the operator makes the back of the connecting fastener body 1 fit together with the mounting plate installed on the photovoltaic panel. When the back of the connecting fastener body 1 fits together with the mounting plate installed on the photovoltaic panel, the operator releases the clamping plate 3. After the clamping plate 3 no longer squeezes the spring 6 through the pull rod 5 and the pressure plate 7, the elastic deformation of the spring 6 is restored, and the spring 6 pushes the pressure plate 7 to move, so that the pressure plate 7 drives the clamping plate 3 to move through the pull rod 5, and the clamping plate 3 drives the anti-sliding block 2 to move, so that the clamping plate 3 and the anti-sliding block 2 are clamped on the surface of the mounting plate installed on the photovoltaic panel, which is convenient for pre-fixing the clamping plate 3 on the mounting plate, thereby improving the convenience of the operator in installing the connecting fastener body 1.

[0024] In other embodiments, a connecting block 14 is provided in the middle of the avoidance groove 15, and the connecting block 14 is slidably connected to the avoidance groove 15, and a fixing plate 10 fixed on the inner wall of the avoidance groove 15 is symmetrically attached to the surface of the connecting block 14, and a traction block 9 is fixed on one side of the fixing plate 10 and the connecting block 14 that are attached to each other, and a traction groove 11 provided on the surface of the traction block 9 is sleeved with a traction groove 11 opened on the connecting block 14, and second abutment plates 13 matching the number of spring grooves 4 are symmetrically fixed to the ends of both sides of the avoidance groove 15, and the end of the second abutment plate 13 is attached to the first abutment plate 12 fixed to the end of the pull rod 5, and a pulling plate 8 is fixed to the end of the connecting block 14. When the operator needs to simultaneously remove the two sets of splints 3 from both sides of the fastener body 1, the operator first pulls the pulling plate 8, and the pulling plate 8 drives the second abutment plate 13 to move through the connecting block 14, so that the first abutment plate 12 can be pulled out of the pull rod 5. The second support plate 13 pushes the first support plate 12 to move. When the second support plate 13 pushes the first support plate 12 to move, the inclined slope set by the second support plate 13 fits with the inclined slope set by the first support plate 12. When the second support plate 13 continues to move, the inclined slope set by the second support plate 13 abuts against the inclined slope set by the first support plate 12. The second support plate 13 pushes the pull rod 5 to move through the first support plate 12, and the pull rod 5 pushes the pressure plate 7 to move, so that the pressure plate 7 moves in the spring groove 4. When the pressure plate 7 moves in the spring groove 4, the pressure plate 7 squeezes the spring 6, causing the spring 6 to undergo elastic deformation. After the spring 6 undergoes elastic deformation, the spring 6 avoids the pressure plate 7, causing the pull rod 5 to push the clamping plate 3 to move, making it convenient for the operator to simultaneously push the two groups of clamping plates 3 away from the two sides of the connecting fastener body 1.

[0025] In other embodiments, the second support plate 13 and the first support plate 12 are both set to have an inclined slope, and the inclined slope surfaces of the first support plate 12 and the second support plate 13 fit together. After the inclined slopes of the second support plate 13 and the first support plate 12 fit together, after the operator pulls the connecting block 14 to move, the connecting block 14 pushes the inclined slope of the first support plate 12 through the inclined slope of the second support plate 13, so that the second support plate 13 pushes the pull rod 5 to move through the first support plate 12.

[0026] In other embodiments, the avoidance groove 15, the connecting block 14 and the middle of the connecting fastener body 1 are all provided with waist-shaped holes of matching shapes. When the operator fits the connecting fastener body 1 and the mounting plate together and needs to use bolts to install the mounting plate, the operator first takes the bolts and passes the bolts through the connecting fastener body 1, the avoidance groove 15 and the waist-shaped holes in the middle of the connecting block 14, so that the connecting fastener body 1, the avoidance groove 15 and the waist-shaped holes in the middle of the connecting block 14 are convenient for the operator to avoid the bolts.

[0027] In other embodiments, a plurality of groups of semicircular protrusions are provided on one side of the anti-sliding block 2 close to the surface of the connecting fastener body 1. When the operator fits the connecting fastener body 1 and the mounting plate installed on the photovoltaic panel together, the operator clamps the clamping plate 3 on the mounting plate installed on the photovoltaic panel, and the clamping plate 3 drives the anti-sliding block 2 to move, so that the anti-sliding block 2 and the mounting plate are fitted together. After the anti-sliding block 2 and the mounting plate are fitted together, the plurality of groups of semicircular through holes provided on the surface of the anti-sliding block 2 facilitate increasing the contact area between the clamping plate 3 and the mounting plate, thereby improving the stability of the clamping plate 3 clamped on the mounting plate through the friction force of the clamping plate 3 on the mounting plate.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
