Movable grooves facilitating movement of the limiting assembly are formed in the two sides of the embedded connecting piece respectively. The embedded connecting piece is of a U-shaped structure. According to the utility model, the embedded connecting piece is designed, and only the connecting piece of the device needs to be pushed into the guide rail during installation, so that the limiting component is extruded by the inner wall of the guide rail to generate inward pressure so as to generate deformation. The hardness and toughness of the material of the connecting piece generate an outward counter force, so that the frictional resistance between the connecting piece and the guide rail is increased, and the connection is realized when the frictional resistance reaches a design value. According to the scheme, the multiple guide rails can be rapidly installed and disassembled at the same time. The installation speed is improved and the installation cost is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a photovoltaic bracket guide rail connector. Background Art

[0002] The global energy crisis has promoted the rapid development of photovoltaic power generation technology. The construction of photovoltaic power stations has become the most important link in the development process. Photovoltaic brackets, as the main components of photovoltaic power generation, are the most basic safety guarantee in photovoltaic power generation. At present, most rooftop distributed projects in the industry use aluminum alloy rails for support. Aluminum alloy profiles are light and beautiful, and are particularly suitable for installation on light roofs or colored steel tile roofs.

[0003] The connection of traditional guide rails is fixed by a combination of T-blocks, aluminum alloy washers and bolts. This installation method has many parts and is time-consuming, resulting in high material costs and bringing certain adverse effects to actual use, so it needs to be improved.

[0004] Most of the existing technologies on the market are mainly based on the combination of connectors and fasteners. The connector is first placed in the appropriate position of the guide rail, and the two guide rails are connected by the top-to-top effect of the fastener locking and fixing. This guide rail connector combination requires many parts, and installation or removal is time-consuming and laborious. For example, the prior art is a guide rail connector for photovoltaic guide rails, application number 202222369815.X. Utility Model Content

[0005] The purpose of the utility model is to provide a photovoltaic support rail connector, which can simultaneously meet the requirements of rapid installation and rapid removal of multiple rails by setting an embedded connection between the rail connector and the rail, using a limit assembly to limit the position, and increasing the friction between the two. The advantages of increasing installation speed and reducing installation costs have brought certain favorable effects to actual use and solved the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A photovoltaic support rail connector, including an embedded connector, and limit assemblies are respectively provided on both sides of the embedded connector. Movable grooves that are conducive to the movement of the limit assembly are respectively provided on both sides of the embedded connector. The embedded connector is U-shaped. The limit assembly includes a first elastic section, a second protruding section, and a third reinforcement section, one end of the first elastic section is fixedly connected to the embedded connector, and the other end of the first elastic section is connected to one end of the third reinforcement section through the second protruding section, and the other end of the third reinforcement section is suspended.

[0007] Of course, the position limiting assembly can also adopt a two-stage design, that is, the third reinforcement section is removed, and the first elastic section and the second protruding section are retained. However, compared with the two-stage design, the three-stage design is more conducive to maintaining the initial elastic deformation after repeated installation and disassembly. Of course, it should be pointed out that when the two-stage design is adopted, the second protruding section is the most suitable solution, and the second spike section is adopted, that is, the third reinforcement section is removed, and the first elastic section and the second spike section are retained.

[0008] The design of the movable groove facilitates the movement of the limit assembly, because the second protruding section enters the inner wall of the guide rail and is squeezed, causing the first elastic section to generate inward pressure and deform. At the same time, due to the hardness and toughness of the material itself, the first elastic section will generate an outward reaction force, thereby increasing the friction between the second protruding section and the inner wall of the guide rail. Among them, the length of the first elastic section is longer than the third reinforcement section, and the second protruding section adopts an arc design, which is more conducive to completing the limit after extrusion and deformation.

[0009] Of course, the embedded connector adopts a U-shaped structure.

[0010] Preferably, the limiting assembly is composed of four limiting assembly units.

[0011] During installation, you only need to push the connector of the device into the guide rail. The symmetrical design of the four limit assembly units is more convenient for pushing in, which can meet the requirements of quick installation and quick disassembly of multiple guide rails.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, limit assemblies are arranged on the left and right sides of the embedded connector, and the limit assemblies are used for limiting and increasing the friction between the two, which can simultaneously meet the requirements of rapid installation and rapid disassembly of multiple guide rails and improve the installation speed.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0021] Embodiment 1,

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a photovoltaic support rail connector, including an embedded connector 1, and limit assemblies 3 are respectively provided on both sides of the embedded connector 1. The limit assembly 3 is composed of four limit assembly units. Movable grooves 2 that are conducive to the movement of the limit assembly 3 are respectively provided on both sides of the embedded connector 1. The limit assembly 3 includes a first elastic section 3c, a second raised section 3b, and a third reinforcement section 3a, one end of the first elastic section 3c is fixedly connected to the embedded connector 1, and the other end of the first elastic section 3c is connected to one end of the third reinforcement section 3a through the second raised section 3b, and the other end of the third reinforcement section 3a is suspended.

[0023] Embodiment 2:

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a photovoltaic support rail connector, comprising an embedded connector 1, and a limit assembly 3 is respectively provided on both sides of the embedded connector 1. Active grooves 2 are respectively provided on both sides of the embedded connector 1 to facilitate the movement of the limit assembly 3. The limit assembly 3 includes a first elastic section 3c, a second convex section 3b, and a third reinforcement section 3a, one end of the first elastic section 3c is fixedly connected to the embedded connector 1, and the other end of the first elastic section 3c is connected to one end of the third reinforcement section 3a through the second convex section 3b, and the other end of the third reinforcement section 3a is suspended.

[0025] The embedded connector 1 has a U-shaped structure. The limit assembly 3 is composed of four limit assembly units, which are two symmetrically designed first limit assembly units 31 and second limit assembly units 32. The first limit assembly unit 31 is inserted into the first guide rail unit 41, and the second limit assembly unit 32 is inserted into the second guide rail unit 42, so that multiple guide rails can be quickly installed and removed.

[0026] The embedded connector 1 includes a first connector part 1a, a second connector part 1b, and a third connector part 1c. The first connector part 1a and the second connector part 1b are symmetrically arranged on the left and right sides of the third connector part 1c. The width of the third reinforcement section 3a is 8mm. The distance from the third reinforcement section 3a to the edge of the embedded connector 1 is 12mm. Of course, the embedded connector 1 can adopt either a regular U-shaped structure or an irregular U-shaped structure.

[0027] Embodiment 2 Compared with Embodiment 1, in Embodiment 2, the embedded connector 1 is in a U-shaped structure. By using the U-shaped structure, limiter components are arranged on the left and right sides of the embedded connector. When installing, the connector of the device only needs to be pushed into the inside of the guide rail, so that the limiter components are squeezed by the inner wall of the guide rail, generating inward pressure and thus deforming. The hardness and toughness of the material of the connector of the device itself generate an outward reaction force, which increases the friction resistance between the connector and the guide rail. When the friction resistance reaches the design value, the connection is achieved.

[0028] When the guide rail and its embedded connector are in a detachable state, quick disassembly can be completed by pulling out the guide rail at the location of the embedded connector.

[0029] It should be pointed out that the utility model is also applicable to the solution of setting a reserved opening on the side of the guide rail. When the limit assembly of the guide rail connector reaches the designated reserved opening of the guide rail, the limit assembly will pop out from the reserved opening, and the reserved opening will prevent the movement of the limit assembly, thereby achieving connection; when disassembling, it is only necessary to press the limit assembly into the guide rail and pull out the guide rail connector to complete the quick disassembly. Both installation and disassembly can be completed in a short time.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
