Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to an adjustable aluminum hook for heavy-load photovoltaics. Background Art

[0002] When installing a photovoltaic system on a roof with tiles, aluminum hooks are used to ensure that the photovoltaic modules can be firmly attached to the roof. The aluminum hooks are fixed to the wooden beams or load-bearing structures of the roof by bolts. Not only does it provide the necessary support, the design of the aluminum hooks also takes into account external forces such as bearing capacity to ensure the stability of the photovoltaic modules.

[0003] At present, the bearing capacity of existing aluminum hooks can meet most practical scenarios. However, most aluminum hooks have a single structure, and the support height and front-to-back distance of the aluminum hooks cannot be adjusted, or the adjustable amount is small, which is not convenient for installation in actual applications. Due to different regions or different roof designs, the wooden beams or load-bearing structures under the tiles are arranged differently. A single style of aluminum hook may not be fully applicable. If the installer does not confirm it in advance, it will be very inconvenient to use it during installation and fixation. Even the arrangement distance of the aluminum hooks is too large to meet the design requirements of the photovoltaic bracket, which will bring safety hazards to the later use, or the distance is too small and the number of installations is large, resulting in increased costs.

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0030] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Reference Figure 1-4 As shown, a heavy-load adjustable aluminum hook for photovoltaics includes a base 1, which is fixed to a wooden beam or a load-bearing structure under a roof tile by screws or other means. The base 1 includes a mounting portion 11, and the mounting portion 11 is connected to a first curved arm 2. The first curved arm 2 includes an inclined portion 23 and a first vertical portion 21. The inclined portion 23 and the first vertical portion 21 are connected by a connecting portion 22. The connecting portion 22 is inclined, and the connection between the connecting portion 22 and the inclined portion 23 and the first vertical portion 21 is thickened and adjusted according to the results obtained by finite element simulation calculation and analysis (the simulated values ​​are selected according to different situations, and this embodiment does not specifically limit and explain it) so that the connection can adapt to a larger load. A first strip groove is provided on the inclined portion 23, and a first bolt 4 passes through the first strip groove and is fixed to the mounting groove 111 of the mounting portion 11. The first bolt 4 can be fixedly moved in the first strip groove.

[0032] The second bent arm 3 includes a second vertical portion 31 and a horizontal portion 32 for installing a guide rail fixing assembly. The guide rail fixing assembly adopts existing technology, and the specific structure can be selected according to different tracks. Therefore, the structure of the guide rail fixing assembly is not specifically limited or described in this embodiment. The connecting portion 22 between the second vertical portion 31 and the horizontal portion 32 is also thickened. A second strip groove is provided on the second vertical portion 31, and the second bolt 5 passes through the second strip groove to be connected to the first vertical portion 21.

[0033] The contact surfaces between the first curved arm 2 and the base 1 and the second curved arm 3 are all toothed, which can make the connection more stable and prevent the first curved arm 2 and the second curved arm 3 from sliding up and down and rotating after locking, and play a multi-level adjustment role when adjusting the relative position. Each tooth is the same size, and moving one tooth adjusts a displacement; through the cooperation of the first strip groove and the second strip groove, the connection between the first curved arm 2 and the base 1 and the second curved arm 3 can be adjusted to a certain extent. The contact surface between the first curved arm 2 and the base 1 is an inclined surface. Adjusting the relative position of the two can change the horizontal distance and vertical height between the hook base 1 and the guide rail fixing assembly. Adjustment between the first curved arm 2 and the second curved arm 3 can change the overall height of the hook. In actual use, it can be adjusted according to different situations encountered.

[0034] A third strip groove is provided on the horizontal portion 32, and the guide rail fixing assembly is fixed to the third strip groove by bolts, so that the guide rail fixing assembly can be fixedly moved on the third strip groove, and the fixed position is selected according to actual conditions.

[0035] The mounting portion 11 is provided with a through hole 112 extending from front to back, which can reduce the weight of the base 1 and the material cost of components while ensuring the structural strength of the base 1 .

[0036] The base 1 also includes a fixing portion 12, which is stepped, and the upper end surface on the left side is lower than the upper end surface on the right side. Through the load stress analysis of the aluminum hook, the fixing portion 12 is subjected to greater force on the side close to the mounting portion 11, so the right side is thickened to meet the requirement of being able to withstand a larger heavy load, and a fixing hole is provided on the fixing portion 12.

[0037] A T-nut 6 is provided in the mounting groove 111, and the T-nut 6 cooperates with the first bolt 4, wherein the width of the upper side of the threaded hole in the T-nut 6 is H1, and the width of the lower side is H2, and H2>H1. This is because through the load stress analysis of the aluminum hook, the lower side of the threaded hole in the T-nut 6 is subjected to greater force, so the lower side is designed to be widened.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
