Description

Technical Field

[0001] The utility model relates to the technical field of installation of solar photovoltaic modules, and particularly relates to a roof hook fixture. Background Art

[0002] With the development of the global economy, new energy power generation technologies have been rapidly developed and applied. Solar energy has become one of the most promising renewable energy sources due to its rich resources, wide distribution, and cleanliness. Solar power systems are the most environmentally friendly power generation methods available. The global solar photovoltaic power generation industry has developed rapidly, with the market application scale constantly expanding, and it is playing an increasingly important role in the development of follow-up energy. In recent years, the state has introduced a number of incentive policies to promote the construction of solar photovoltaic power stations. Now, many people want to install solar photovoltaic power generation systems on their own rooftops. However, many rooftops are made of ceramic tiles, and it is very inconvenient to install solar battery components on this type of rooftop. Usually, a special solar battery installation rack needs to be pre-erected on the tile roof, which not only has a high erection cost but also a high installation difficulty and is inconvenient to install. To solve the installation of photovoltaic brackets on ceramic tile rooftops, a tile roof hook has been introduced in the market. When installing this connector, the ceramic tiles on the roof need to be lifted, and after the connector is hooked and fixed on the ceramic tiles, the ceramic tiles are then laid back to their original positions.

[0003] Chinese Patent Document CN106253808A discloses a fixed hook rack assembly for a tile roof solar cell module, which includes a base, a rail mounting rack, connecting screws, and a rail connection limiting block. The base includes a fixed connection edge and a clamping edge, and a kidney-shaped hole is provided on the fixed connection edge. The rail mounting rack includes a connecting vertical edge, a horizontal edge, and a rail mounting edge. The two ends of the horizontal edge are perpendicularly and fixedly connected to the connecting vertical edge and the rail mounting edge respectively. A connecting threaded hole is opened on the connecting vertical edge. The connecting screws pass through the kidney-shaped hole and the connecting threaded hole to fixedly connect the fixed connection edge and the connecting vertical edge. An anti-deformation support edge is provided on the outer side of the connection between the rail mounting edge and the horizontal edge, and a load-bearing edge is provided on the rail mounting edge. The rail is fixedly installed on the rail mounting edge through the connecting screws passing through the rail mounting groove and the rail connection limiting block. This invention is light in weight, has good load-bearing strength, is not easily deformed, has good wind resistance and corrosion resistance, and has a long service life. It can meet the requirements of high-quality solar brackets and eliminate potential safety hazards.

[0004] However, the fixed hook rack assembly of CN106253808A has a traditional T-shaped block installation method for fixing the rail, that is, the rail is fixed through a T-shaped combination of a rail connection limiting block and a connecting screw. This method has certain requirements for the rail. The rail needs to have a cavity for accommodating the rail connection limiting block, and the rail connection block needs to be first placed into this cavity and then connected through the connecting screw. In this way, on the one hand, there is still room for further improvement in the installation efficiency, and on the other hand, there is also room for further improvement in the adaptability to different rails. Summary of the Invention

[0005] In view of this, in order to solve the above technical problems, the object of the present utility model is to provide a roof hook fixture, which can further improve the installation efficiency and further improve the adaptability to different guide rails.

Detailed implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0030] See Figures 1 - 4 As shown, a roof hook fixture includes a base 1, a retaining hoop 2, a first half-card slot 3, a second half-card slot 4, and an assembly rail 5.

[0031] The retaining hoop 2 has one end fixed to the base 1; the other end of the retaining hoop 2 is provided with a strip-shaped first coupling hole 21;

[0032] The first half-card slot 3 has a second coupling hole; one side of the first half-card slot 3 is in close contact with the retaining hoop 2;

[0033] The second half-card slot 4 has a third coupling hole 41; the end 42 of the second half-card slot 4 abuts against the end 31 of the first half-card slot 3, and the end 31 of the first half-card slot 3 is wedge-shaped;

[0034] For the assembly rail 5, the first half-card slot 3 and the second half-card slot 4 are combined into a card slot to clamp the assembly rail 5; a first bolt 6 passes through the first coupling hole 21, the second coupling hole, and the third coupling hole 41 to fix the assembly rail 5 to the retaining hoop 2.

[0035] The installation method of the assembly rail and the combined card slot adopts a snap-fastening installation method, which only requires three steps: one snap, two locks, and three adjustments to complete the rail installation. One snap means snapping the assembly rail into the card slot; two locks mean tightening with the first bolt; three adjustments mean that the up and down height can be adjusted through the strip-shaped first coupling hole.

[0036] Among them, the first bolt 6 passing through the first coupling hole 21, the second coupling hole, and the third coupling hole 41 can be pre-assembled. The first bolt 6 is equipped with a matching nut and can be tightened in cooperation with the nut.

[0037] In the installation design of this buckle, the end 31 of the first half-card slot 3 is wedge-shaped, and the end of the second half-card slot 4 abuts against the end of the first half-card slot 3. In this way, with the wedge-shaped surface, the tighter it is locked, the better the force-bearing strength is achieved. That is, the tighter the first bolt is locked, the closer the end of the second half-card slot 4 is to the wedge-shaped end of the first half-card slot 3.

[0038] In this way, the assembly rail 5 is clamped through the combination of the first half-card slot 3 and the second half-card slot 4 to form a card slot; the first bolt 6 passes through the first coupling hole 21, the second coupling hole, and the third coupling hole 41 to fix the assembly rail 5 on the retaining hoop 2. Thus, on the one hand, compared with the installation method of the traditional T-shaped block, as long as the assembly rail is pre-assembled by the first bolt and then clamped and locked, the installation can be completed, thereby further improving the installation efficiency; on the other hand, the combined card slot can adapt to a variety of different guide rails (i.e., assembly rails), thereby further improving the adaptability to different guide rails.

[0039] As a specific implementation manner, one side of the first half-card slot 3 is provided with a first corrugated surface 32, and the retaining hoop 2 is provided with a second corrugated surface 22. The second corrugated surface 22 is in fitting contact with the first corrugated surface 32, so that one side of the first half-card slot is tightly attached to the retaining hoop. In this way, through the contact limit of the corrugated surface, the friction force is increased, and the up-and-down adjustment can be better realized.

[0040] As a specific implementation manner, extension parts 54 are provided on both sides of the second track 52, and the extension parts are provided with third corrugated surfaces. The first half-card slot 3 and the second half-card slot 4 are respectively provided with corresponding fourth corrugated surfaces. When the first half-card slot 3 and the second half-card slot 4 are combined to form a card slot to clamp the extension part 54, the fourth corrugated surface is in fitting contact with the third corrugated surface. In this way, the installation contact surface adopts the contact limit of the corrugated surface to ensure that the installation limit is in place and avoid construction errors.

[0041] As a specific implementation manner, the assembly rail 5 includes a first track 51 and a second track 52, and the first track 51 and the second track 52 are connected in a plug-in manner. For example, the first track 51 can be inserted into the second track 52.

[0042] As a further preferably specific implementation manner, a limiter 53 for restricting the plug-in position is provided on the first track 51. In this way, the limiter 53 can be set to achieve the plug-in limit during the installation of the track under the condition of ensuring the connection strength.

[0043] As a specific implementation manner, one end of the base 1 is provided with an installation hole 11 for being fixedly fitted on the roof. Multiple installation holes can be provided and fixed by screwing the screws 12 into the installation holes 11.

[0044] As a specific implementation manner, a relatively arranged first adjusting column 13 and a second adjusting column 14 are fixed on the base 1. The first adjusting column 13 is provided with a plurality of third clamping grooves 15 arranged vertically; the second adjusting column 14 is provided with a plurality of fourth clamping grooves 16 arranged vertically; the number and positions of the third clamping grooves 15 and the fourth clamping grooves 16 correspond to each other; the bottom end of the holding hoop 2 extends respectively to both sides with a first hook 23 and a second hook. The first hook 23 is clamped in the third clamping groove 15; the second hook is clamped in the fourth clamping groove 16 at the corresponding height position. A threaded hole is provided in the middle of the holding hoop 2, and a second bolt 7 is screwed into the threaded hole of the holding hoop 2 and abuts against the bottom of the base 1, so that the holding hoop 2 is fixed on the base 1. In this way, through the plurality of third clamping grooves and fourth clamping grooves arranged vertically, the first hook and the second hook can be clamped at different positions to realize the adjustment of different heights in the up and down positions, so as to be applicable to various roof heights and can be adapted to a variety of different drop heights.

[0045] As a specific implementation manner, both the first track 51 and the second track 52 are tracks made of aluminum alloy. In this way, by using tracks made of aluminum alloy, while achieving high strength, the price of the tracks can tend to the lowest price in the local market.

[0046] For the complete set of product fasteners of this roof hook fixture, such as the first bolt and the second bolt, they can all be of the same unified specification. In this way, only one tool is needed to complete the full set of installations, further improving the on-site installation efficiency.

[0047] It should be noted that the serial numbers such as the first and the second in this specification are used to distinguish components or parts with the same function or the same structure, and do not contain an order, nor imply relative importance. The corresponding components or parts are relatively independent, such as the first bolt and the second bolt, etc.

[0048] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent embodiments or changes made without departing from the technical spirit of the present invention should be included in the protection scope of the present invention.
