The locking mechanism includes a connecting rod 6, a positioning block 7, a transmission seat 8, a large gear ring 9, a winding roller 11, a small gear ring 10, a cable 12, a rotating sleeve 18, a movable connecting block 13, a pull rod 14, a sleeve 15, a locking spring 16, a rotating block 17, a deceleration rod 19 and a wave groove 20.

[0027] In the embodiment of the present utility model, the top end of the support column 5 penetrates through the connecting rod 6, and the connecting rod 6 is fixedly connected to the support column 5. A positioning block 7 is fixedly mounted on the outer wall of the side of the photovoltaic panel 2 close to the mounting base 1. A transmission seat 8 is fixedly mounted on the outer wall of the side of the photovoltaic panel 2 close to the mounting base 1. The connecting rod 6 penetrates through the transmission seat 8, and the connecting rod 6 is rotatably connected to the transmission seat 8. A large gear ring 9 is sleeved on the outer wall of the connecting rod 6 located inside the transmission seat 8. A winding roller 11 is rotatably mounted on the inner wall of the transmission seat 8. A small gear ring 10 penetrates through the winding roller 11, and the small gear ring 10 is fixedly connected to the winding roller 11. A cable 12 is sleeved on the arc-shaped outer wall of the winding roller 11. A rotating sleeve 18 is rotatably mounted on the outer wall of the end of the transmission seat 8. A movable connecting block 13 is slidably mounted on the inner wall of the rotating sleeve 18. The top end of a pull rod 14 is movably connected to the inner wall of the movable connecting block 13. A sleeve 15 is sleeved on the outer wall of the pull rod 14. A locking spring 16 is fixedly connected to the bottom inner wall of the pull rod 14 and the sleeve 15. The bottom end of the sleeve 15 is hinged to a rotating block 17. The rotating block 17 is rotatably mounted on the side wall of the support column 5. A deceleration rod 19 is fixedly mounted on the inner wall of the rotating sleeve 18. Wave grooves 20 are formed on the upper and lower outer walls of the deceleration rod 19.

[0028] In an embodiment of the present utility model, the number of photovoltaic panels 2 is set to two groups, and the two groups of photovoltaic panels 2 are mirror - arranged on the left and right sides of the mounting base 1. At the same time, the bottom of the mounting base 1 is hollow - arranged to facilitate the installation of the driving motor. In addition, the end of the adjusting screw rod 3 is rotatably installed on the inner wall of the top of the mounting base 1, and the side wall of the threaded sleeve 4 is slidably connected to the inner wall of the mounting base 1 to guide and limit the movement of the threaded sleeve 4. Specifically, when the adjusting screw rod 3 rotates, the threaded sleeve 4 can only move vertically along the side wall of the mounting base 1 and will not rotate with the rotation of the adjusting screw rod 3. Further, the bottom of the mounting base 1 is provided with universal wheels with buckles, and the top of the mounting base 1 is provided with a telescopic handle to facilitate people's use and carrying. At the same time, the number of positioning blocks 7 is set to two groups, and the connecting rod 6 passes through the positioning blocks 7, and the positioning blocks 7 are rotatably connected to the connecting rod 6, that is, the support column 5 is hinged to the positioning blocks 7 through the connecting rod 6 on the back of the photovoltaic panel 2. Specifically, when starting the driving motor to drive the adjusting screw rod 3 to rotate, the threaded sleeve 4 moves upward, cooperating with the support column 5 to jack up the photovoltaic panel 2 upward, so that the photovoltaic panel 2 rotates around the hinge point between it and the mounting base 1 until the photovoltaic panel 2 rotates to a horizontal state. During this process, relative rotation occurs between the support column 5 and the positioning blocks 7, that is, the connecting rod 6 rotates relative to the positioning blocks 7.

[0029] Specifically, the small gear ring 10 meshes with the large gear ring 9, and the diameter of the small gear ring 10 is smaller than that of the large gear ring 9, so that when the large gear ring 9 rotates, the small gear ring 10 can rotate through a larger angle to better pull the cable 12. When the connecting rod 6 rotates relative to the transmission seat 8, through the rotation of the large gear ring 9, the small gear ring 10 and the winding roller 11 are driven to rotate. Further, the two ends of the cable 12 are respectively fixedly connected to the arc - shaped outer wall of the winding roller 11 and the outer wall of the end of the movable connection block 13, so that the rotation of the winding roller 11 will pull the movable connection block 13 through the cable 12, making it move along the inner wall of the rotating sleeve 18 towards the transmission seat 8. In addition, the connecting part between the pull rod 14 and the movable connection block 13 can rotate freely. During the process of the photovoltaic panel 2 being propped up, through the relative rotation between the connecting rod 6 and the transmission seat 8, the large gear ring 9 drives the small gear ring 10 to rotate, and then the winding roller 11 winds up the cable 12. At this time, in cooperation with the pulling of the cable 12 on the movable connection block 13, the locking spring 16 is tightened by the pull rod 14, so that both sides of the photovoltaic panel 2 have a supporting and protecting effect. Cooperating with the support column 5, a stable triangle is formed on the back of the photovoltaic panel 2 to ensure the stability of the photovoltaic panel 2 after it is propped up and prevent it from being damaged due to external forces.

[0030] In addition, a slot that matches the deceleration rod 19 is provided at the end of the movable connection block 13, and a rubber ridge that matches the wave groove 20 is provided on the inner surface of the slot, so that when the deceleration rod 19 is inserted into the interior of the movable connection block 13 along the slot and pulled out from the slot, the movement speed of the movable connection block 13 is reduced by the restriction of the rubber ridge and the wave groove 20, thereby preventing the device from shaking to a large extent when subjected to external force, affecting the stable use of the photovoltaic panel 2.

[0031] In the utility model, when in use, the driving motor is started to drive the adjusting screw rod 3 to rotate, the threaded sleeve 4 moves upward, and cooperates with the support column 5 to lift the photovoltaic panel 2 upward, so that the photovoltaic panel 2 rotates at the hinge point between it and the mounting seat 1 until the photovoltaic panel 2 rotates to a horizontal state. During this process, the support column 5 and the positioning block 7 rotate relative to each other, that is, the connecting rod 6 rotates relative to the positioning block 7. During this process, a locking mechanism is provided, and the large gear ring 9 drives the small gear ring 10 to rotate through the relative rotation between the connecting rod 6 and the transmission seat 8, thereby causing the winding roller 11 to reel in the cable 12. At this time, the cable 12 cooperates with the active The movable connecting block 13 is pulled to cooperate with the pull rod 14 to tighten the locking spring 16, so that both sides of the photovoltaic panel 2 have a supporting and protective effect at the same time, and cooperate with the support column 5 to form a stable triangle on the back of the photovoltaic panel 2 to ensure the stability of the photovoltaic panel 2 after it is propped up, and to prevent it from being damaged by external forces. At the same time, when the deceleration rod 19 is inserted into the interior of the movable connecting block 13 along the slot and pulled out of the slot, the movement speed of the movable connecting block 13 is reduced through the restriction of the rubber ridges and the wave grooves 20, thereby preventing the device from shaking violently when subjected to external forces, affecting the stable use of the photovoltaic panel 2.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
