[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0023] See also Figure 1-Figure 4As shown, a limiting connector for a photovoltaic support rail provided in this embodiment includes a rail 1, guide grooves 1-1 are provided on both sides of the rail 1, and an external connector 2, guide components 3 are provided on both sides of the external connector 2, and an elastic limiting component 4 is provided at the bottom, and the guide component 3 is slidably connected to the guide groove 1-1; the external connector 2 includes a bottom plate 2-1 and baffles 2-2 provided on both sides, and the elastic limiting component 4 includes a spring 4-1 connected to the bottom plate 2-1 at one end, the spring 4-1 is fixed to the external connector 2 by rivets, and a spike 4-2 is provided at the end of the spring 4-1, and the sliding bottom of the rail 1 is slidably abutted against the spring 4-1. Two elastic limiting components 4 are mirror-set for each external connector 2. The cross-section of the guide groove 1-1 is provided with a convex opening. The baffle 2-2 is provided with a stress opening 5, and the guide component 3 includes a guide 3-1 connected to the stress opening 5, and each stress opening 5 is connected to two guides 3-1 with openings facing each other. One end of the guide member 3 - 1 is connected to the inner side of the stress opening 5 .

[0024] The baffle plate 2 - 2 is provided with a pressing groove 6 below the spring sheet 4 - 1 , and the notch specification of the pressing groove 6 is larger than that of the spring sheet 4 - 1 .

[0025] The bottom plate 2-1 and the two side baffles 2-2 are integrally formed to improve the self-strength of the externally wrapped connector 2; when connected, the guide component 3 and the guide groove 1-1 push the externally wrapped connector 2 toward the rear side relative to each other, and the two guide members 3-1 arranged opposite to each other are slidably clamped in the guide groove 1-1 respectively, guiding the guide component 3 to move horizontally to prevent it from tilting during the sliding process with the guide rail 1, resulting in unstable connection; the externally wrapped connector 2 is pushed until the end of the guide rail 1 is located at the position of the circular hole 8, the spring sheet 4-1 and the bottom of the guide rail 1 are in conflict, and the spring sheet 4-1 is inclined upward relative to the top surface of the bottom plate 2-1 to have a resistance force on the guide rail, thereby fixing the guide rail 1; a spike 4-2 is provided at the end of the spring sheet 4-1, which fits with the bottom of the guide rail 1. When the guide rail 1 is not moved toward the outward end manually, the spike 4-2 pierces the bottom wall of the guide rail 1 to provide a pulling force to the middle of the externally wrapped connector 2 for the guide rail 1, thereby fixing the guide rail 1, preventing the guide rail 1 from falling off from the externally wrapped connector 2, and further improving the stability of the guide rail connection.

[0026] A pressing groove 6 is provided under each spring sheet 4-1, and one end of the spring sheet 4-1 is connected to the end of the pressing groove 6 away from the circular hole 8. During the connection process of the guide rail 1, the outsourced connecting member 2 is pushed toward the guide rail 1, and the bottom of the guide rail 1 slides in contact with the top of the spring sheet 4-1, so that the spring sheet 4-1 is pressed into the pressing groove 6 to reduce the friction between the spring sheet 4-1, the spike 4-2 and the guide rail 1, thereby avoiding the friction loss between the bottom of the guide rail 1 and the elastic limit assembly 4 after multiple connections and disassembly, and reducing the firmness of the connection.

[0027] In the above, two groups of elastic limit assemblies 4 are mirror-imaged to facilitate sliding and fixing the ends of the two guide rails 1 to be connected, thereby realizing quick connection and installation.

[0028] In the above, when disassembly is required, a tool is used to pull the spring piece 4-1, and the spring piece 4-1 and the spike 4-2 are separated from the bottom of the guide rail 1. At this time, the outer connector 2 is pulled synchronously to quickly separate and disassemble it from the guide rail 1. This structural design is more convenient for disassembly.

[0029] In summary: a limiting connector for a photovoltaic bracket guide rail is adopted in this embodiment, and the guide component used in its structure guides the outboard connector during connection and installation, thereby improving the relative position of the outboard connector to the guide rail during sliding, thereby improving the stability of the connection; the elastic limit component used in its structure has a novel structure, and is fixed by the elastic force of the spring sheet abutting against the guide rail, and cooperates with the spikes to prevent the guide rail from falling off, further improving the connection stability; the pressing groove arranged in its structure is opposite to the spring sheet, and the spring sheet can be downwardly retracted into the pressing groove, reducing the friction between the spring sheet, the spikes and the guide rail, avoiding the friction loss between the bottom of the guide rail and the elastic limit component after multiple connections and disassembly, and reducing the firmness of the connection.

[0030] The above is only an embodiment of the present invention, and the known specific technical solutions and / or characteristics in the solution are not described in detail here.
