Technical Field

[0001] The present invention relates to the technical field of fasteners, and more particularly to a transition assembly for fixing purlins and photovoltaic components. Background Art

[0002] With the rapid development of photovoltaic power generation projects, the requirements for the installation of photovoltaic modules and the processing of photovoltaic brackets are becoming increasingly higher.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The core of the present invention is to provide a switching assembly for fixing purlins and photovoltaic modules, which can realize the fixation of photovoltaic modules and purlins without opening row holes or fixed holes on the purlins.

[0032] Please refer to Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of a switching assembly for fixing purlins and photovoltaic modules provided in a specific embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram showing a connection assembly for fixing a purlin and a photovoltaic assembly connected to the photovoltaic assembly and the purlin respectively; Figure 3 for Figure 1 Schematic diagram of the structure of the fastener.

[0033] The present invention provides a transition assembly for fixing a purlin and a photovoltaic assembly, comprising a fastener 1, a slider 2 and a locking member 3.

[0034] Specifically, the fastener 1 is used to be connected to the pressing block 5 that presses the photovoltaic component 4 through the first bolt 6. That is to say, the connection method between the fastener 1 and the photovoltaic component 4 is the same as the connection method between the purlin 7 and the photovoltaic component 4 in the prior art. For example, a hole for the first bolt 6 to pass through can be directly opened on the fastener 1, so as to realize the connection between the fastener 1 and the pressing block 5 that presses the photovoltaic component 4.

[0035] The slider 2 is slidably disposed on the fastener 1 to move relative to the fastener 1 toward the purlin 7 .

[0036] The locking member 3 and the fastener 1 are connected in a lockable and releasable manner. During the locking process of the locking member 3, the slider 2 is driven to move toward the purlin 7. When the locking member 3 and the fastener 1 are locked, the locking member 3 presses the slider 2, so that the slider 2 presses the purlin 7, thereby achieving the fixation of the adapter assembly and the purlin 7.

[0037] It can be seen that the present invention achieves the purpose of installing the photovoltaic module 4 on the purlin 7 by introducing an adapter assembly for fixing the purlin and the photovoltaic module so that the adapter assembly is fixedly connected to the photovoltaic module 4 and the purlin 7 respectively.

[0038] Compared with the prior art, in which rows of holes or fixed holes are drilled on the purlin 7 and the photovoltaic module 4 is fixed to the purlin 7 by bolts, the adapter assembly for fixing the purlin and the photovoltaic module provided by the present invention can avoid drilling rows of holes or fixed holes on the purlin 7. On the one hand, the structural strength of the purlin 7 is improved, making the structure of the purlin 7 more stable; on the other hand, since the adapter assembly presses the slider 2 through the locking member 3 so that the slider 2 presses the purlin 7, there is no restriction on the model and structure of the purlin 7, thereby improving the versatility of the purlin 7 and making the purlin 7 adaptable to photovoltaic modules 4 of different specifications.

[0039] like Figure 3 As shown, considering the specific structure of the fastener 1 used to connect with the pressing block 5 for pressing the photovoltaic component 4, on the basis of the above embodiment, the fastener 1 includes a slot 11 for inserting the head of the first bolt 6, and a stop plate 12 is provided at the notch of the slot 11 for preventing the head of the first bolt 6 from escaping from the slot 11, and the stop plate 12 is provided with a clearance opening for the screw rod of the first bolt 6 to pass through.

[0040] When in use, the head of the first bolt 6 is inserted into the slot 11 from one side of the slot 11 , and the screw rod of the first bolt 6 is passed through the opening, and then the first bolt 6 is moved to a suitable position along the length direction of the slot 11 .

[0041] It can be seen from this that this structure can adapt to the installation of photovoltaic components 4 of different specifications, can adjust the fixed position of the fastener 1 and the pressing block 5 that presses the photovoltaic component 4, and has high versatility; on the other hand, compared to directly drilling a hole on the fastener 1, this structure can also avoid the drilling process and can be integrally formed through a mold, reducing processing costs and time.

[0042] At this time, the first bolt 6 is preferably a T-bolt.

[0043] It can be understood that when the first bolt 6 is tightened, the end face of the head of the first bolt 6 presses the stop plate 12. In order to improve the strength of the clearance opening and avoid the clearance opening from being crushed, etc., on the basis of the above embodiment, the clearance opening is provided with a folded edge portion 13 bent toward the inside of the slot 11, and this edge portion is used to contact the end face of the head of the first bolt 6.

[0044] That is to say, in this embodiment, the structural strength of the opening is improved by providing the folded edge portion 13, so that the fastener 1 and the pressing block 5 are fixed more firmly.

[0045] The present embodiment does not specifically limit the distance that the folded edge portion 13 extends into the slot 11 , and those skilled in the art can set it according to actual needs.

[0046] Taking into account the convenience of installation, on the basis of the above-mentioned embodiments, the fastener 1 also includes a slide groove 14 for sliding from one end of the purlin 7 into the lateral edge of the purlin 7 and a hanging plate 15 for hanging on the top of the purlin 7, and the hanging plate 15 is vertically connected to the side of the slide groove 14 away from the slider 2.

[0047] During installation, the slide groove 14 is slid from one end of the purlin 7 into the lateral edge of the purlin 7. At this time, the hanging plate 15 is located at the top of the purlin 7, and the fastener 1 can slide to any position of the purlin 7. Therefore, the fastener 1 can be slid to the required installation position according to the installation requirements of the photovoltaic module 4. When the fastener 1 slides into place, the fastener 1 is released, and the fastener 1 is hung on the top of the purlin 7 under the action of the hanging plate 15 to facilitate installation.

[0048] It should be noted that, during installation, any number of adapter assemblies for fixing purlins and photovoltaic assemblies may be selected according to the installation requirements of the photovoltaic assemblies 4 .

[0049] Taking into account the specific setting method of the slider 2, on the basis of the above embodiment, the fastener 1 also includes a support plate 16 for supporting the slider 2, the support plate 16 is vertically connected to the other side of the slide groove 14, and the support plate 16 is arranged parallel to the hanging plate 15, the slider 2 is inserted between the support plate 16 and the hanging plate 15, and the slider 2 can move in the direction close to the slide groove 14 so that the slider 2 presses the side of the purlin 7.

[0050] That is to say, there is a preset distance between the support plate 16 and the hanging plate 15 so that the slider 2 can be inserted therebetween, and it can be ensured that under the pressing force of the locking member 3, the slider 2 can move toward the direction close to the slide groove 14 so that the slider 2 presses the side of the purlin 7.

[0051] That is, in this embodiment, the slider 2 is used to press the side of the purlin 7, so that the fastener 1 is fixed to the purlin 7. Preferably, the slider 2 is provided with anti-slip teeth on one side facing the side of the purlin 7.

[0052] It is understandable that in order to achieve a better fixing effect between the fastener 1 and the purlin 7, the gap between the slider 2 and the inner side of the top of the purlin 7 is as small as possible.

[0053] Taking into account the simplicity and feasibility of the specific structure of the locking member 3, on the basis of the above embodiment, the locking member 3 is a T-bolt, and the support plate 16 is provided with a mounting hole for the T-bolt to pass through, and there is a preset distance between the mounting hole and the slide groove 14, so that when the T-bolt is tightened by a nut matching therewith, the rectangular head of the T-bolt pushes the slider 2 close to the slide groove 14 to press the side of the purlin 7.

[0054] It can be understood that the slider 2 is located between the mounting hole and the slide groove 14. When the slider 2 is inserted between the hanging plate 15 and the support plate 16, the T-bolt is pre-installed so that the rectangular head of the T-bolt is hung on the support plate 16, and a nut is installed at the end of the T-bolt.

[0055] It should be noted that the preset distance between the mounting hole and the slide groove 14 needs to ensure that when the T-bolt is not tightened, the narrow side of the rectangular head of the T-bolt is parallel to the side of the slider 2, and the slider 2 does not interfere with the pre-installation of the T-bolt; and in the process of tightening the T-bolt by the nut, the rectangular head of the T-bolt has a tendency to rotate due to the tightening force applied to it. At this time, due to the mechanical limitation of the side of the slider 2, the rectangular head of the interfering T-bolt is rotated, so that the rectangular head of the T-bolt is pressed against the slider 2, exerting a driving force on the slider 2, and then the slider 2 presses the side of the purlin 7, thereby fixing the purlin 7 and the fastener 1.

[0056] Taking into account the limitation of the side of the T-bolt away from the slider 2, based on the above embodiment, a limiting plate 17 is provided on the side of the support plate 16 away from the slide groove 14 and is arranged parallel to the slider 2 to limit the rectangular head.

[0057] Taking into account the convenience of processing, preferably, based on the above embodiment, the fastener 1 is an integrally molded fastener.

[0058] That is to say, the above-mentioned structural features of the fastener 1 are obtained through one-piece molding, which can greatly reduce the processing cost and time.

[0059] Preferably, the fastener 1 is an aluminum alloy fastener.

[0060] Taking into account the stability of the connection between the fastener 1 and the pressing block 5 that presses the photovoltaic assembly 4, on the basis of the above-mentioned embodiments, the mounting plate 15 and the stop plate 12 are arranged coplanarly.

[0061] That is to say, after the first bolt 6 is tightened, the surfaces of the hanging plate 15 and the stop plate 12 are pressed against the bottom surface of the pressing block 5 to increase the contact area between the fastener 1 and the pressing block 5 and improve the stability of the connection between the two.

[0062] In order to improve the structural strength of the fastener 1 itself, on the basis of the above-mentioned embodiments, a reinforcing plate 18 for improving the structural strength is provided between the outer side of the slide groove 14 and the groove bottom of the insertion slot 11 .

[0063] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0064] The above is a detailed introduction to the adapter assembly for fixing purlins and photovoltaic modules provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
