[0032] The existing guide rail connecting structure generally adopts a fixing mode that the mounting frame and the guide rail limiting structure are combined and assembled by bolts. The specific installation process is as follows: first, the limiting structure is clamped and positioned with the side wall of the guide rail, and then the bolts are passed through the mounting frame reserved hole and the limiting structure to realize connection and fixation. Therefore, during the installation process, the operator needs to continuously hold the clamping state of the limiting structure and the guide rail with one hand to prevent the rotation or displacement of the limiting structure and the guide rail, and simultaneously completes the bolt passing, alignment and preliminary locking operation with the other hand. The operator can release the holding of the limiting structure only after the bolt is completely locked. The whole installation process is complicated and requires high operation coordination, which greatly increases the construction difficulty. When disassembling and maintaining, the bolts need to be loosened first, so that the limiting structure can be separated from the guide rail and the mounting frame. Similarly, the disassembly process is complicated and inefficient. In order to solve the above technical problems, the technical scheme is as follows:

[0033] Referring to Figs. 1-7 As shown in the drawings, a rail connecting structure for a photovoltaic support comprises an L-shaped connecting frame 1, a supporting platform 3 for buckling with a rail 2, the supporting platform 3 being fixed to one side of the L-shaped connecting frame 1 through a connecting assembly 4, the supporting platform 3 comprising a first supporting part 31 and a second supporting part 32 arranged left and right, a buckling groove for buckling with the rail 2 being formed between the top parts of the first supporting part 31 and the second supporting part 32, the shape of the buckling groove being adapted to the shape of the bottom part of the rail 2, the bottom part of the side of the second supporting part 32 close to the first supporting part 31 being provided with a fixed shaft 33 arranged along the length direction of the rail 2, and the bottom part of the side of the first supporting part 31 close to the second supporting part 32 being provided with a positioning hole 34 for the fixed shaft 33 to be inserted into and rotate around.

[0034] Therefore, during installation, the supporting platform 3 is buckled with the bottom part of the rail 2, and then the L-shaped connecting frame 1 is fixed with the supporting platform 3 through the connecting assembly 4. Specifically, the fixed shaft 33 of the second supporting part 32 is aligned and inserted into the positioning hole 34 of the first supporting part 31, so that the second supporting part 32 can rotate around the fixed shaft 33 in the positioning hole 34. Then, the L-shaped connecting frame 1 and the supporting platform 3 are pre-assembled through the connecting assembly 4, and the buckling grooves at the top parts of the first supporting part 31 and the second supporting part 32 are in an open state to facilitate the insertion of the rail. Then, the top part of the first supporting part 31 is clamped into the buckling groove on one side of the bottom part of the rail 2, at this time, the bottom part of the rail 2 is preliminarily positioned with the side of the buckling groove, and then the L-shaped connecting frame 1 and the supporting platform 3 are further locked through the connecting assembly 4, at this time, the second supporting part 32 rotates around the positioning hole 34 under the drive of the fixed shaft 33, so that the buckling groove gradually closes until the bottom part of the rail 2 is completely locked, achieving quick locking. During disassembly, only the connecting assembly 4 needs to be loosened, so that the second supporting part 32 reversely rotates around the fixed shaft 33, the buckling groove is opened, and the rail 2 can be easily removed without the need for additional disassembly of the limiting structure. The whole process is simple to operate and can be completed with one hand, significantly improving the installation and maintenance efficiency.

[0035] The present application cooperates the structures of the rotatable second supporting part, the fixed shaft and the positioning hole, so that the supporting platform automatically realizes the buckling and locking of the rail during the locking process of the connecting assembly, without the need for manual continuous force limiting with both hands, significantly reducing the installation difficulty and improving the operation convenience and connection reliability. During disassembly, the connecting assembly is reversely loosened, the buckling groove is gradually opened, and the rail can be easily taken out, achieving quick assembly and disassembly and greatly improving the maintenance efficiency.

[0036] Further, the connecting assembly 4 comprises a locking bolt 41, a gasket 42 sleeved on the locking bolt 41, and an elastic member 43 between the head of the locking bolt 41 and the gasket 42; the side plate of the L-shaped connecting bracket 1 is provided with a mounting hole 11 through which the locking bolt 41 passes, the first supporting part 31 is provided with a waist-shaped hole 35 through which the locking bolt 41 passes, and the second supporting part 32 is provided, on the side close to the first supporting part 31, with a threaded hole 36 connected with the locking bolt 41;

[0037] In use, the elastic member 43 and the gasket 42 are sleeved on the locking bolt 41 in sequence, then the gasket 42 abuts against the outside of the side plate of the L-shaped connecting bracket 1, the locking bolt 41 passes through the mounting hole 11 and the waist-shaped hole 35 in sequence and is screwed into the threaded hole 36, and the head of the locking bolt 41 is kept at a proper distance from the L-shaped connecting bracket 1, at this time the elastic member 43 generates a pre-tightening force, drives the fixed shaft 33 of the second supporting part 32 to rotate around the positioning hole 34, and promotes the left side of the second supporting part 32 to abut against the first supporting part 31, so that the buckle groove is in a closed state, and the first supporting part 31 keeps a clamping state with the L-shaped connecting bracket 1, and the track connecting structure forms a pre-tightening effect; when the track 2 is installed, the track 2 is aligned with the buckle groove and is lightly pressed downward, so that the second supporting part 32 is forced to rotate outward around the fixed shaft 33 against the pre-tightening force of the elastic member 43, the buckle groove is opened, the track 2 is embedded into the groove by inertia, after the track is installed, the elastic member 43 is unfolded and pushes the second supporting part 32 to rotate back to the original position, the buckle groove is automatically closed and locks the bottom of the track 2, and finally the locking bolt 41 is completely screwed, so that the head of the locking bolt 41 presses the gasket 42, and the installation of the track is completed;

[0038] When the track 2 needs to be taken out before the locking bolt 41 is completely screwed, the track 2 can be directly taken out upward, at this time the second supporting part 32 rotates outward around the fixed shaft 33, the buckle groove is opened, and the track 2 can be separated from the supporting platform, after the track 2 is separated from the supporting platform, the second supporting part 32 is automatically returned to the original position under the action of the elastic member 43, and the buckle groove returns to a pre-closed state, which is convenient for the next installation;

[0039] Therefore, when the track is installed, the first supporting part 31 and the second supporting part 32 form a buckle structure that is automatically returned to the original position, so that the track is quickly installed and self-locked, the stability of the connection is ensured, and the track installation and disassembly process is efficient and convenient.

[0040] The mounting hole 11 is vertically arranged in a long strip shape, and the top end extends through the top of the side plate of the L-shaped connecting frame 1, so that in use, the first supporting part 31 and the second supporting part 32 can be connected first, the elastic member 43 and the gasket 42 are sequentially sleeved on the locking bolt 41, then the gasket 42 abuts against the outside of the first supporting part 31, the locking bolt 41 passes through the waist-shaped hole 35 and is screwed into the threaded hole 36, thereby realizing the pre-assembly of the supporting platform 3 and the connecting assembly 4. At this time, the pre-assembled supporting platform 3 and the connecting assembly 4 are first connected with the track as a whole, and then the L-shaped connecting frame 1 is slid into the space between the gasket 42 and the first supporting part 31 through the mounting hole 11, which facilitates the separate installation of the L-shaped connecting frame 1 and the supporting platform 3, is suitable for high-altitude or narrow-space operation scenarios, effectively reduces the installation difficulty, and improves the operation safety and efficiency; and the up-down position of the L-shaped connecting frame 1 can be flexibly adjusted according to actual installation requirements, which is suitable for different installation heights and further improves the installation flexibility and adaptability.

[0041] Further, the L-shaped connecting frame 1 is provided with a limiting protrusion 12 extending inward at the top end of the side close to the first supporting part 31, and the first supporting part 31 is provided with a limiting step 37 matched with the limiting protrusion 12 at the end away from the second supporting part 32. Therefore, when the track is installed and the locking bolt 41 is completely tightened, the limiting protrusion 12 effectively limits the limiting step 37, preventing the first supporting part 31 from slipping upward during use and causing the supporting platform 3 to separate from the L-shaped connecting frame 1, thereby ensuring the stability and safety of the overall structure.

[0042] Further, the first supporting part 31 is provided with first corrugations horizontally arranged at equal intervals away from the second supporting part 32, and the inner and outer sides of the side plate of the L-shaped connecting frame 1 are provided with second corrugations matched with the first corrugations. Through the engagement of the first corrugations and the second corrugations, the connection stability between the supporting platform and the L-shaped connecting frame is enhanced, effectively preventing relative sliding and improving the anti-vibration and load-bearing capacity of the overall structure, so that firm connection can be maintained even under complex working conditions.

[0043] The inner and outer sides of the track 2 are formed with arc-shaped flanges protruding outward, and the two ends of the clamping groove are formed with arc-shaped sockets matched with the arc-shaped flanges. In use, the arc-shaped flanges of the track are aligned and clamped into the clamping groove, and the arc-shaped flanges are matched with the arc-shaped sockets to realize quick clamping and stable connection of the track and the supporting platform.

[0044] At the same time, the first supporting part 31 and the second supporting part 32 are provided with guide slopes 38 at the top for the arc-shaped flanges to enter the clamping groove. When the track is pressed down, the guide slopes 38 guide the arc-shaped flanges to smoothly slide into the clamping groove, realizing quick alignment and smooth installation of the track.

[0045] The second supporting part 32 rotates around the first supporting part 31 by an angle of 0-10°, and when the second supporting part 32 is in a 0° closed state with the first supporting part 31, it forms a closed buckling groove together with the first supporting part 31, thereby ensuring stable clamping of the track 2; when rotated to a 10° unfolded state, the track can be quickly loaded into the buckling groove.

[0046] The elastic member 43 is a spiral spring.

[0047] The L-shaped connecting frame 1 is provided with a reinforcing rib 13 connecting the side plate and the bottom plate, thereby effectively improving the overall structural strength of the L-shaped connecting frame.

[0048] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
