[0002] The support guide rail for installing a photovoltaic solar panel usually has slots at the upper and lower ends of the guide rail, and a blocking member is arranged near the slot opening to prevent the slider for fixing the photovoltaic solar panel from falling off the slot. However, due to the vibration of the support caused by the external environment, the slider for fixing the photovoltaic solar panel will become loose, resulting in unreliable installation and poor overall effect. Accordingly, the utility model provides a guide rail of a photovoltaic bracket. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies in the prior art and provide a guide rail of a photovoltaic bracket, which has the characteristics of secondary locking and reliable connection.

Openings are respectively provided at the top and bottom of the profile body, and a U-shaped frame arranged inside the profile body is connected to the openings. The U-shaped frame extends along the length direction of the profile body. Horizontal extending edge guards are respectively provided on the left and right sides of the openings. The U-shaped frame has a bottom plate, and a row of process holes arranged at intervals along the length direction are opened on the bottom plate. Elastic pieces with one end connected to the hole wall of the process holes are arranged in the process holes, and connection holes are opened on the elastic pieces.

[0005] The utility model is further provided as: At least one locking block is slidably connected inside the profile body. The locking block has a locking upper plate that abuts against one U-shaped frame and a locking lower plate that abuts against the other U-shaped frame. Spherical protrusions for jacking up the elastic pieces are respectively provided on the locking lower plate and the locking upper plate.

[0006] The utility model is further provided as: Two locking blocks are slidably connected inside the profile body.

[0007] The utility model is further provided as: A linear slide rail extending along its extending trajectory is provided on the profile body. A linear slide groove matching the linear slide rail is provided on the locking block, and the linear slide rail is slidably connected in the linear slide groove.

[0008] The utility model is further provided as: The spherical protrusion also penetrates into the connection hole.

[0009] The utility model is further provided as: The intervals between adjacent two process holes on the same bottom plate are equal.

[0010] In summary, the utility model has the following beneficial effects: For the photovoltaic support guide rail involved in the utility model, by moving the locking block to a preset position on the profile body, the spherical protrusion on the locking block jacks up the corresponding elastic piece until the elastic piece abuts against the slider that slides into the U-shaped frame and is used to fix the photovoltaic solar panel, avoiding the loosening of the fasteners on the slider due to vibration. While eliminating vibration, it plays a secondary locking role, making the connection more reliable, with a complete overall function and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following describes the preferred implementation solutions of the present utility model in combination with specific embodiments. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0016] The present utility model will be further described below in combination with the drawings and preferred embodiments.

[0017] Embodiment 1

[0018] Referring to Figures 1 to 4 As shown, a photovoltaic support guide rail involved in this embodiment includes a profile body 1 that extends forward and backward in a straight line and has a rectangular frame-shaped cross-section. Openings 2 are respectively provided at the top and bottom of the profile body 1. A U-shaped frame 3 provided inside the profile body is connected to the openings 2. The U-shaped frame 3 extends along the length direction of the profile body 1. On the left and right sides of the openings 2, horizontal extending edge guards 4 are respectively provided. The U-shaped frame 3 has a bottom plate 31. A row of process holes 32 arranged at intervals along the length direction are opened on the bottom plate 31. Elastic pieces 33 with one end connected to the hole wall of the process holes are provided in the process holes 32. Connection holes 34 are opened on the elastic pieces 33.

[0019] Further, two locking blocks 5 are slidably connected inside the profile body 1. The locking block 5 has a locking upper plate 51 that abuts against one of the U-shaped frames and a locking lower plate 52 that abuts against the other U-shaped frame. Spherical protrusions 53 for jacking up the elastic sheet 33 are respectively provided on the locking lower plate 52 and the locking upper plate 51.

[0020] Further, a linear slide rail 6 extending along its extension trajectory is provided on the profile body 1. A linear chute 7 matching the linear slide rail is provided on the locking block 5, and the linear slide rail 6 is slidably connected inside the linear chute 7.

[0021] Further, the adjacent two process holes 32 on the same bottom plate 31 are equally spaced.

[0022] In this embodiment, when the slider for fixing the photovoltaic solar panel is snapped into the U-shaped frame 3 on the profile body 1 and fixed by fasteners, the locking block 5 can be correspondingly moved until the locking block 5 is located directly below the corresponding slider. At this time, because the spherical protrusion 53 pushes the corresponding elastic sheet 33, the elastic sheet 33 extends out of the process hole 32 and abuts against the bottom of the slider, playing a role in eliminating vibration and secondary locking.

[0023] Among them, through the setting of the linear slide rail 6 in cooperation with the linear chute 7, it plays a guiding role when the locking block 5 slides relative to the profile body 1.

[0024] Embodiment 2

[0025] See Figures 1 to 4 As shown, a photovoltaic support rail involved in this embodiment is further provided, on the basis of Embodiment 1, such that the spherical protrusion 53 also penetrates into the connection hole 34.

[0026] In this embodiment, by setting the spherical protrusion 53 to be also capable of penetrating into the connection hole 34, it plays a positioning role, making the movement position of the locking block 5 more accurate.

[0027] The photovoltaic support rail involved in the present utility model moves the locking block to a preset position of the profile body, so that the spherical protrusion on the locking block jacks up the corresponding elastic sheet until the elastic sheet abuts against the slider that slides into the U-shaped frame and is used to fix the photovoltaic solar panel, avoiding the loosening of the fasteners on the slider due to vibration, eliminating vibration and playing a secondary locking role at the same time, making the connection more reliable, with a complete overall function and strong practicability.
