In the embodiments described below, a mounting frame and a support structure are illustrated by way of example, however, it should be understood that the photovoltaic panel fastener of the present invention is equally applicable to mounting frames and support structures having other similar structures.

Referring first to fig. 2a and 2b, there is shown one form of assembly frame 10, the assembly frame 10 is for example an elongated box structure, and includes a frame body 11 and a photovoltaic panel clamping groove 12 disposed at the top of the frame body 11, the frame body 11 includes a cavity 112 provided with a slot 111 for receiving a photovoltaic panel fastener, the slot 111 for example extending along the length of the assembly frame 10. Wherein the side of the frame body 11 provided with the slot 111 comprises an outer contact surface 113 adapted to be in contact with the support structure, and an inner abutment surface 114 located within the cavity 112, the inner abutment surface 114 being adapted to cooperate with a corresponding part of a photovoltaic panel fastener.

Alternatively, the threaded fastener is a bolt 30 with a nut 31 as shown. In some embodiments, a spacer 50 is disposed between the nut 31 of the bolt 30 and the support structure 20, and the stud segment of the bolt 30 can be engaged with the photovoltaic panel fastener via the mounting hole 22 and the slot 111 of the mounting frame 10, thereby fastening the mounting frame 10 and the support structure 20.

According to the utility model discloses a conceive, integrate on photovoltaic board fastener with the threaded connection portion, can realize the meshing between bolt and the threaded connection portion through operating bolt on the bearing structure to convert operating space into the great space on the bearing structure from the narrow and small space on the assembly frame, the operating personnel's of being convenient for assembly and dismantlement, simple operation. In addition, compare in current structure, the utility model discloses a photovoltaic board fastener has the bulk strength of increase for photovoltaic board module after the assembly is more firm reliable, can adapt to multiple application environment.

Fig. 4 a-4 f illustrate one embodiment of a photovoltaic panel fastener 60. The photovoltaic panel fastener 60 generally includes a main body portion 61, a threaded engagement portion 62, a pair of snap ribs 63, and a pair of support ribs 64. Wherein the main body portion 61 is substantially parallel to the mounting plane 21 of the support structure 20, the threaded engagement portion 62 extends perpendicularly to the main body portion 61 and has a passage 622 (fig. 4e) for receiving the bolt 30, and the inner wall of the passage 622 is provided with an internal thread 621 that cooperates with the external thread 32 (fig. 5b) of the bolt 30. As shown in fig. 4c, a pair of clamping ribs 63 respectively extend from the end surface of the main body portion 61 and are symmetrically arranged along the first direction D1 with respect to the central axis X-X of the screw joint portion 62 to be suitable for clamping the assembly frame 10. As shown in fig. 4D, a pair of support ribs 64 are symmetrically arranged with respect to the central axis X-X of the screw joint 62 along a second direction D2, each support rib 64 being connected to one of the snap ribs 63 and extending beyond the free end of the snap rib 63 to be adapted to abut against the mounting plane 21 of the support structure 20, wherein the second direction D2 is perpendicular to the first direction D1, as shown in fig. 4 e. In this way, the snap-in ribs and the support ribs can be laid out in a compact manner, so that the space occupied by the photovoltaic panel fastener is smaller, in particular for narrow spaces in the assembly frame. In addition, the mode that joint rib and support rib are symmetrical arrangement respectively also makes structural design simpler, simultaneously, and the atress is more even when playing support and joint effect. In the following description, only one of the catching ribs and one of the supporting ribs are described for clarity.

In the illustrated embodiment, the threaded engagement portion 62 is illustratively shown in the form of a nut having a circular cross-section. It should be understood that the outer peripheral shape of the screw engagement portion is not limited to that shown in the drawings, and may be square or other shapes as long as the inner thread thereof is adapted to fit with the outer thread of the bolt.

In certain embodiments, not shown, the threaded engagement portion 62 and the pair of snap ribs 63 can be disposed on the same side of the body portion 61, i.e., both below the body portion 61 when oriented as shown in the figures, thereby further reducing the physical size of the photovoltaic panel fastener. In this manner, the spacing between the pair of support ribs 64 does not interfere with the outer periphery of the threaded engagement portion. In the embodiment shown in the drawings, the screw-threaded engagement portion 62 and the pair of snap ribs 63 are respectively disposed on both sides of the body portion 61, in such a manner that the spacing between the pair of support ribs 64 is advantageously made smaller than the outer diameter of the mating bolt 30. Thus, in some instances, the photovoltaic panel fastener 60 may be directly pre-installed on the support structure 20 by sleeving the photovoltaic panel fastener over the stud 30 shown in fig. 3a and 3b such that the end of the stud 30 is inserted between the support ribs 64 and retained.

As shown in fig. 4a to 4f and fig. 5b, in some embodiments, the support rib 64 is configured to be substantially U-shaped, and includes a first support part 641 extending toward the main body part 61, a second support part 642 for abutting against the mounting plane 21 of the support structure 20, and a support connection part 643 between the first support part 641 and the second support part 642, wherein the second support part 642 is connected with the clamping rib 63 through an arc-shaped transition part 65. In this way, a reliable supporting function can be obtained by the second support portion 642 having an increased contact area between the support rib 64 and the mounting plane 21 of the support structure 20. The use of the arcuate transition 65 to connect the support rib 64 and the snap rib 63 also helps to achieve the desired fastening strength, as will be more clearly understood in conjunction with the detailed description below. Advantageously, as shown in fig. 4c, the arc-shaped transition portion 65 is bent inward from the free end of the catching rib 63 to extend to the second supporting portion 642. Thus, the support rib 64 does not interfere with the catching rib 63 when deformed by a force. Moreover, this also enables the width of the support rib 64 to be configured to be equal to or less than the width of the slot 111 of the fitting frame 10 without affecting the mounting with the fitting frame 10.

In order to provide the support rib 64 with increased structural strength, it is advantageous to provide a reinforcing bead 644 extending from the first support part 641 to the second support part 642 on the support rib 64. Alternatively, the reinforcing rib 644 may continuously extend from the first support part 641 to the support connection part 643 and to the second support part 642 as shown in the figure; alternatively, the rib may be formed in a multi-stage structure extending discontinuously, that is, a separate rib may be formed on each of the first support part 641, the support connection part 643 and the second support part 642, which also serves to increase the strength of the support rib.

In some embodiments, the snap ribs 63 are notched to reduce the rigidity of the snap ribs. As shown in fig. 4a and 4b, notches 66 may be formed at the free ends of the snap ribs 63 adjacent the arcuate transition 65 to help reduce the insertion force required when the mounting frame 10 is assembled with the photovoltaic panel fastener 60. Alternatively, more than one notch may be provided, and the notch may be provided at any suitable position on the snap rib, for example, by opening at a central position of the snap rib to form the notch.

The photovoltaic panel fastener according to the present invention is advantageously configured to include a pre-assembled state and a fastened state. As can be seen from fig. 4c, when the photovoltaic panel fastener is not fastened, i.e. in the pre-assembled state, the U-shaped structure of the support rib 64 forms a first gap d1 between the first support part 641 and the main body part 61, and once the fastening force is applied and the photovoltaic panel fastener is in the fastened state, the first support part 641 is pressed against the main body part 61 under the fastening force, and the first gap d1 is not visible. In other words, the main body 61 assists in providing a supporting function, and whether the fastening is in place can be intuitively known from the perspective of an operator through whether the first gap d1 disappears, so that the fastening force can be controllably applied, and the disadvantage that the component is damaged due to excessive force is avoided. In some embodiments, the above-described tightening force is applied by threading bolt 30 into threaded engagement portion 62 along passage 622 of threaded engagement portion 62, as will be described in detail below.

The manner in which a photovoltaic panel fastener according to an embodiment of the present invention is applied to a mounting device of a photovoltaic panel module is described below with reference to fig. 5a to 7 b.

In the embodiment shown, the mounting arrangement of the photovoltaic panel module comprises the mounting frame 10, the support structure 20 and the photovoltaic panel fasteners 60 as described above. After the bolts 30 have been installed on the support structure 20 as shown in fig. 3a and 3b, as shown in fig. 5a to 5c, the photovoltaic panel fastener 60 may be fitted over the stud segments of the bolts 30 from above the mounting plane 21 of the support structure 20 such that the bolts 30 engage with part of the internal threads 621 of the screw joint 62, while the bolts 30 are held by the support connection 643 of a pair of support ribs as seen in fig. 5 b. At this time, the photovoltaic panel fastener 60 is in the first state of initial positioning, or in the pre-loaded state without force, and there is a first gap d1 between the first supporting portion 641 of the supporting rib 64 and the main body portion 61, as shown in fig. 5b, while the second supporting portion 642 is in contact with the mounting plane 21 of the supporting structure 20 without force. Also, an operator may manually rotate the photovoltaic panel fastener to place it in a desired orientation. Due to this structural design and the corresponding manner of operation, as described above, in certain embodiments, the photovoltaic panel fastener 60 and the support structure 20 may be considered as a pre-assembled assembly, such as pre-assembling a plurality of adapted bolts 30 and photovoltaic panel fasteners 60 on the support structure 20, thereby facilitating adaptation to a variety of different assembly applications. For example, the photovoltaic panel is generally rectangular in shape, and at least four photovoltaic panel fasteners 60 on two support structures 20 are required to secure the photovoltaic panel, so that the pre-assembled assembly can effectively reduce the assembly time and labor cost during the initial assembly period.

In a subsequent operation, as shown in fig. 6a to 6b, the fitting frame 10 is inserted from above the photovoltaic panel fastener, with the groove facing downward in the arrow direction in fig. 6 a. As mentioned above, the snap ribs 63 are configured for snap fitting the frame 10, for which purpose a pair of snap ribs 63 of the photovoltaic panel fastener may be configured to be adapted to be stopped by the inner abutment surface 114 within the cavity 112 after insertion from the slot. That is, when the fitting frame 10 is inserted downward, the bottom thereof contacts and presses the surfaces of the pair of catching ribs 63, thereby deforming the pair of catching ribs 63 toward each other until the fitting frame 10 completely passes and the outer contact surface 113 of the bottom thereof contacts the mounting plane 21 of the support structure, the catching ribs 63 are restored and stopped by the inner abutment surfaces 114, which is why notches are provided on the catching ribs 63 to reduce rigidity, so that the fitting frame is easily inserted. At this time, the photovoltaic panel fastener is in the second state of being assembled in the cavity of the assembly frame, but is still in the unstressed pre-assembled state, and a first gap d1 exists between the first supporting part 641 and the main body part 61. Furthermore, as can be seen from fig. 6a and 6b, a second gap d2 is also formed between the snap rib 63 and the inner abutment surface 114, so that the fitting frame 10 can be horizontally moved along the mounting plane 21, for example, in the orientation shown in fig. 6b to adjust the position, thereby ensuring the accuracy of positioning.

When in position, as shown in fig. 7a and 7b, the operator may rotate the bolt 30 further upward in the direction of the arrow from below the support structure so that the threaded engagement portion 62 of the photovoltaic panel fastener moves downward under the threaded engagement until the snap rib 63 presses against the inner abutment surface 114 of the fitting frame 10, the second gap d2 not being visible, while applying a torque during the rotation of the bolt to obtain the desired fastening strength. Due to the arrangement of the arc-shaped transition part, when torque is applied to deform the support rib, the arc-shaped transition part is also deformed correspondingly, so that a wider deformation interval, namely a fastening force interval, is given to the support rib. Moreover, the presence of the arcuate transition also makes the bolt 30 less susceptible to failure after tightening than a rigid contact. At this time, the photovoltaic panel fastener is in a third state of fastening the mounting frame 10 and the supporting structure 20, that is, a fastening state of applying a fastening action, as seen from the figure, the first gap d1 is not visible, and the first supporting portion 641 abuts against the main body portion 61, so that the overall strength of the photovoltaic panel fastener is enhanced, and the fastening action is more stable and reliable. In addition, in the fastening state, the arc transition part enables the assembly frame to have a certain elastic variable in the fastening direction, and further has an anti-vibration effect.

Conversely, when the detaching operation is required, the detaching operation can be conveniently and rapidly performed by reversely rotating the bolt 30 under the support structure 20 so that the screw-threaded joint 62 of the photovoltaic panel fastener 60 is moved upward by the screw-threaded engagement and is restored to the state shown in fig. 6 a. It is thus clear that compare in current photovoltaic board fastening mode, according to the utility model discloses a photovoltaic board fastener simple structure, manufacturing are easy, only need less power and simple operation can obtain firm connection in the installation, use extensively.

It should be understood herein that the embodiments shown in the figures merely show alternative configurations, shapes, sizes and arrangements of the various optional components of the mounting device for photovoltaic panel fasteners and photovoltaic panel modules according to the present invention, however, they are merely illustrative and not limiting, and that other shapes, sizes and arrangements may be adopted without departing from the spirit and scope of the present invention.

The technical content and technical features of the present invention have been disclosed above, but it should be understood that various changes and modifications can be made to the concept disclosed above by those skilled in the art under the inventive concept of the present invention, and all fall within the scope of the present invention. The above description of embodiments is intended to be illustrative, and not restrictive, and the scope of the invention is defined by the appended claims.
