Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation structure technology, specifically to an adjustable pressure block assembly. Background Technology

[0002] As the global energy transition towards clean energy progresses, photovoltaic (PV) power generation capacity is surging and its application scenarios are becoming increasingly diverse. The stability and precision of PV panel mounting directly impact system efficiency and safety. PV panels are typically fixed to PV support structures using clamping modules. Generally, these clamping modules need to withstand various loads and adapt to temperature variations, requiring the device to have sufficient strength and adjustability.

[0003] However, existing photovoltaic (PV) panel mounting components are mostly single-structure, resulting in limited adjustment range and narrow applicability. They struggle to meet the high compensation requirements of complex environments, and their adjustment operations are cumbersome, with insufficient long-term stability, leading to increased installation costs and limited deployment flexibility. For example, utility model patent CN206977358U discloses an adjustable mounting block for PV supports, which features two sets of interlocking positioning teeth. The interlocking position of these teeth is adjusted to accommodate the thickness of the PV panel. However, this adjustable block can only adjust a few fixed points and lacks flexibility. For instance, if the PV support has three settings to accommodate 25mm, 30mm, and 35mm thick PV panels respectively, it is no longer suitable for panels between 25-30mm and 30-35mm thick. If the PV panel changes due to environmental or other factors, the adjustable block becomes unusable. In other words, existing adjustable blocks have a small adjustment range and low flexibility. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an adjustable pressure block assembly to improve the flexibility of the use of adjustable pressure blocks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable pressure block assembly includes an adjustable locking block, an adjustable pressure block, a fastener, a locking bolt, and a bolt pressure block; The adjustable card block is provided with multiple positioning protrusions arranged at intervals in sequence; The adjustable pressure block includes a snap-fit ​​part and a fixing part. The fixing part has a U-shaped structure, including two groove sidewalls and a groove bottom. The inner and outer surfaces of the groove bottom of the fixing part are both arc surfaces, and the groove bottom is provided with an elongated hole penetrating the groove bottom. The length direction of the elongated hole is parallel to the line connecting the two groove sidewalls. The snap-fit ​​part is connected to the upper part of one of the groove sidewalls, and the snap-fit ​​part is provided with a snap groove that cooperates with the positioning protrusion. The bolt clamping block is provided with bolt holes for bolts to pass through, and the lower end face of the bolt clamping block is an arc surface that matches the bottom of the groove; The locking bolt passes through the bolt hole and the oblong hole in sequence and is then locked to the fastener.

[0006] The adjustable pressure block also includes a support for pressing against the upper surface of the fastener, the support being connected to the lower side wall of another groove.

[0007] The adjustable locking block includes a pressing part and an adjusting part, which are connected to form an inverted L-shaped structure; the lower end face of the pressing part is used to press the photovoltaic panel; the adjusting part is provided with the positioning protrusion on the side facing the adjustable locking block.

[0008] The lower end face of the crimping part is provided with several ribs.

[0009] The card slot is located at the upper end of the card connector, and the opening of the card slot faces the adjustment part of the adjustable card block.

[0010] The positioning protrusion includes a connecting part and an engaging part. The engaging part is connected to the adjusting part of the adjustable block through the connecting part. The engaging part has a round arch structure and the radius of the engaging part is greater than the thickness of the connecting part. The slot is adapted to the shape of the engaging part.

[0011] The sidewall thickness of the slot is less than the distance between two adjacent positioning protrusions.

[0012] The fastener has a fixing hole, and the locking bolt passes through the fixing hole and is locked to the nut.

[0013] The fastener is provided with a snap-fit ​​groove for engaging with the photovoltaic bracket.

[0014] By adopting the above solution, this utility model sets the fixing part of the adjustable pressure block into a U-shaped structure, and provides an elongated hole at the bottom of the groove of the fixing part. Simultaneously, the lower end face of the bolt pressure block is provided with an arc surface adapted to the fixing part. Therefore, the locking position between the adjustable pressure block, the locking pressure block, and the locking bolt can be adjusted. When the locking position of the fixing part of the adjustable pressure block and the locking bolt is changed, the slot position of the adjustable pressure block will shift upwards or downwards (a certain amount of rotation will also occur between the slot and the positioning protrusion). At the same time, the adjustable locking block can also adaptively move upwards or downwards according to the thickness of the photovoltaic panel. Therefore, by adjusting the different assembly methods of the adjustable pressure block and the adjustable locking block, an easy-to-operate, adjustable, and adaptive height adjustment function is achieved, providing a widely applicable and flexible solution for photovoltaic fixing systems.

Detailed Implementation

[0017] like Figure 1-6 As shown, this utility model discloses an adjustable pressure block assembly, which includes an adjustable locking block 10, an adjustable pressure block 20, a fastener 30, a locking bolt 40, and a bolt pressure block 50. The adjustable pressure block 20 and the adjustable locking block 10 are combined by sliding in from the side to achieve a fastening effect. By adjusting the different assembly methods of the adjustable pressure block 20 and the adjustable locking block 10, an easy-to-operate, adjustable, and adaptive height adjustment function can be achieved, providing a solution with wide applicability and flexible deployment for photovoltaic fixing systems.

[0018] Specifically, the adjustable locking block 10 includes a pressing part 11 and an adjusting part 12, which are connected to form an inverted L-shaped structure. The lower end face of the pressing part 11 is used to press the photovoltaic panel 60. To increase the connection stability between the pressing part 11 and the photovoltaic panel 60, several ribs 111 are provided on the lower end face of the pressing part 11. The adjusting part 12 cooperates with the adjustable locking block 20. The adjusting part 12 has a plurality of positioning protrusions 13 arranged sequentially at intervals on the side facing the adjustable locking block 20. The positioning protrusions 13 include a connecting part 131 and an engaging part 132. The engaging part 132 is connected to the adjusting part 12 of the adjustable locking block 10 through the connecting part 131. The engaging part 132 has a circular arch structure, and the radius of the engaging part 132 is greater than the thickness of the connecting part 131.

[0019] The adjustable pressure block 20 includes a snap-fit ​​part 21 and a fixing part 22. The fixing part 22 has a U-shaped structure, including two groove sidewalls 221 and a groove bottom 222. The inner and outer surfaces of the groove bottom 222 of the fixing part 22 are both arc surfaces, and an elongated hole 223 penetrating the groove bottom 222 is provided on the groove bottom 222. The length direction of the elongated hole 223 is parallel to the line connecting the two groove sidewalls 221. The snap-fit ​​part 21 is connected to the upper part of one of the groove sidewalls 221 of the fixing part 22. The snap-fit ​​part 21 has a snap groove 211 that cooperates with the positioning protrusion 13. The snap groove 211 is located at the upper end of the snap-fit ​​part 21, and the opening of the snap groove 211 faces the adjustment part 12 of the adjustable pressure block 10. The shape of the snap groove 211 is adapted to the shape of the engagement part 132, and the thickness of the sidewall of the snap groove 211 is less than the distance between two adjacent positioning protrusions 13.

[0020] The slot 211 engages with different positioning protrusions 13, indicating that the adjustable pressure block assembly is adapted to photovoltaic panels 60 of different thicknesses. In order to improve the stability of the connection of the adjustable pressure block 20, the adjustable pressure block 20 also includes a support portion 24 for pressing against the upper end face of the fastener 30, which is connected below the slot sidewall 221 of the unconnected locking portion 21.

[0021] The fastener 30 has a snap-fit ​​groove 32 for engaging with the photovoltaic bracket 70. The bolt pressure block 50 has a bolt hole 51 for the bolt to pass through, and the lower end face of the bolt pressure block 50 is an arc surface that mates with the bottom of the groove 222. The locking bolt 40 passes through the bolt hole 51 and the elongated hole 223 in sequence and is then locked to the fastener 30. In this embodiment, the fastener 30 has a fixing hole 31, and the locking bolt 40 passes through this fixing hole 31 and is then locked to the nut 41. To make the connection between the entire adjustable pressure block assembly and the photovoltaic panel 60 more stable, a spring washer 42 is provided above the bolt pressure block 50. A flat washer 43 and a spring washer 42 are arranged between the fastener 30 and the nut 41 from top to bottom. At this time, the locking bolt 40 passes through a spring washer 42, the bolt pressure block 50, the adjustable pressure block 20, the fastener 30, the flat washer 43, and another spring washer 42 in sequence and is then locked to the nut 41.

[0022] When the adjustable pressure block assembly of this utility model is used to fix the photovoltaic panel 60, the pressing part 11 of the adjustable locking block 10 presses against the upper end of the photovoltaic panel 60, and the photovoltaic bracket 70 is engaged in the locking groove 32 of the fastener 30. The bolt pressure block 50 fits in the groove bottom 222 of the adjustable pressure block 20, and the locking bolt 40 passes through the elongated hole 223, the bolt hole 51 and the fixing hole 31 in sequence and is locked with the nut 41, thereby fixing the photovoltaic panel 60 to the photovoltaic bracket 70. At this time, the locking groove 211 of the adjustable pressure block 20 engages with one of the positioning protrusions 13 on the adjustable locking block 10, and the support part 24 of the adjustable pressure block 20 presses against the upper end face of the fastener 30. The setting of the support part 24 can make the connection between the adjustable pressure block and other components more stable. Of course, it is also feasible not to set the support part 24. If the support part 24 is not set, the fixing part 22 directly presses against the upper end face of the fastener 30.

[0023] The slot 211, in conjunction with different positioning protrusions 13, indicates that the adjustable pressure block assembly is adapted to photovoltaic panels 60 of different thicknesses. In this embodiment, the adjustable block 10 is provided with three positioning protrusions 13, which are, from top to bottom, the first positioning protrusion, the second positioning protrusion, and the third positioning protrusion. Figure 7 , 10 As shown in Figure 13, when the slot 211 engages with the first positioning protrusion, the adjustable pressure block assembly is adapted to a photovoltaic panel 60 with a thickness of 30mm. When the slot 211 engages with the second positioning protrusion, the adjustable pressure block assembly is adapted to a photovoltaic panel 60 with a thickness of 35mm. When the slot 211 engages with the third positioning protrusion, the adjustable pressure block assembly is adapted to a photovoltaic panel 60 with a thickness of 40mm.

[0024] This invention features a U-shaped structure for the fixing part 22 of the adjustable pressure block 20, with an elongated hole 223 at the bottom 222 of the groove in the fixing part 22. Simultaneously, the lower end face of the bolt pressure block 50 is provided with an arc surface adapted to the fixing part 22. Therefore, the locking position between the adjustable pressure block, the locking pressure block, and the locking bolt 40 can be adjusted. When the locking position of the fixing part 22 of the adjustable pressure block 20 and the locking bolt 40 is changed, the position of the slot 211 of the adjustable pressure block 20 will shift upwards or downwards (a certain amount of rotation will also occur between the slot 211 and the positioning protrusion 13). Simultaneously, the adjustable locking block 10 can also adaptively move upwards or downwards according to the thickness of the photovoltaic panel 60.

[0025] If the thickness of the photovoltaic panel 60 changes due to environmental factors, or if a photovoltaic panel 60 of a different thickness is mistakenly taken due to human error, it can still be used as long as the thickness difference is not significant.

[0026] For example, Figure 8 This is a schematic diagram of the structure of the adjustable pressure block assembly adapted to a 28mm photovoltaic panel when the first positioning protrusion engages with the slot 211. Figure 9 This is a schematic diagram showing the structure of the adjustable pressure block assembly for a 25mm photovoltaic panel when the first positioning protrusion engages with the slot 211. Therefore, even with the slot 211 engaging with the first positioning protrusion, the adjustable pressure block assembly of this invention can still accommodate photovoltaic panels 60 with a thickness of 25-30mm. In this case, the locking bolt 40 is positioned in the elongated hole 223 of the fixing part 22, biased towards the adjustable pressure block 10.

[0027] Figure 11 A schematic diagram of the structure for the adjustable pressure block assembly to fit a 33mm photovoltaic panel when the second positioning protrusion engages with the slot 211; Figure 12 This is a schematic diagram showing the structure of the adjustable pressure block assembly for a 30mm photovoltaic panel when the second positioning protrusion engages with the slot 211. Therefore, even with the slot 211 engaging with the second positioning protrusion, the adjustable pressure block assembly of this invention can still accommodate photovoltaic panels 60 with a thickness of 30-35mm. In this case, the locking bolt 40 is positioned in the elongated hole 223 of the fixing part 22, biased towards the adjustable pressure block 10.

[0028] Figure 14 This is a schematic diagram of the adjustable pressure block assembly for a 38mm photovoltaic panel when the second positioning protrusion engages with the slot 211. Figure 15 This is a schematic diagram showing the structure of the adjustable pressure block assembly for a 35mm photovoltaic panel when the second positioning protrusion engages with the slot 211. Therefore, even when the slot 211 engages with the third positioning protrusion, the adjustable pressure block assembly of this invention can still accommodate photovoltaic panels 60 with a thickness of 35-40mm. In this case, the fixing position of the locking bolt 40 in the elongated hole 223 of the fixing part 22 is biased towards the adjustable pressure block 10.

[0029] Figure 16 This is a schematic diagram of the structure of the third positioning protrusion adapted to a 42mm photovoltaic panel in this embodiment. Therefore, when the slot 211 cooperates with the third positioning protrusion, this invention can also adapt to photovoltaic panels 60 with a thickness greater than 40mm. In this case, the fixing position of the locking bolt 40 in the elongated hole 223 of the fixing part 22 is away from the adjustable locking block 10. Similarly, when the slot 211 cooperates with the first positioning protrusion, this invention can also adapt to photovoltaic panels 60 with a thickness greater than 30mm. When the slot 211 cooperates with the second positioning protrusion, this invention can also adapt to photovoltaic panels 60 with a thickness greater than 35mm. Users can choose the appropriate installation method according to the usage environment.

[0030] The positioning protrusion 13 in this invention includes a connecting portion 131 and an engaging portion 132. This means that after the slot 211 engages with the positioning protrusion 13, there is still a certain distance between the edge of the slot 211 facing the adjustable block 10 and the adjusting portion 12 of the adjustable block 10. Simultaneously, the sidewall thickness of the slot 211 is less than the distance between two adjacent positioning protrusions 13. Therefore, when the slot 211 rotates with the positioning protrusion 13, the slot 211 is not restricted by the adjacent positioning protrusions 13 and the adjusting portion 12.

[0031] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
