[0007] A jig handling cart for adjusting the center of gravity, comprising: a cart, a base is installed below the cart, and an adjustment seat is installed on the surface of the base. A hydraulic cylinder is fixedly installed at the center of the surface of the adjustment seat. A push block is installed at the output end of the hydraulic cylinder. The outside of the push block is movably connected with an adjusting arm, and a rotating shaft for rotation is arranged in the middle of the adjusting arm. A movable shaft member is installed between the upper end of the adjusting arm and the push block. A telescopic rod is fixedly connected to the bottom of the cart. A support frame is movably sleeved outside the lower end of the telescopic rod. Wheels are installed on both sides of the bottom of the base. A driver is installed inside the wheels. A push handle is fixedly connected to one side of the cart.
[0008] As a further scheme in the utility model, the telescopic rod is fixedly connected to the bottom of the cart, and the cart is movably connected with the support frame through the telescopic rod.
[0009] As a further scheme in the utility model, a telescopic cylinder is installed inside the support frame, and an installation frame is installed below the telescopic cylinder. An auxiliary wheel is movably installed inside the installation frame.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1 to 4 , the embodiment of the present invention provides a jig handling trolley for adjusting the center of gravity, including: a trolley 1, a base 3 is installed below the trolley 1, and an adjustment seat 10 is installed on the surface of the base 3. A hydraulic cylinder 16 is fixedly installed at the center of the surface of the adjustment seat 10. A push block 14 is installed at the output end of the hydraulic cylinder 16. The outside of the push block 14 is movably connected with an adjusting arm 11. A rotating shaft 12 for rotation is arranged in the middle of the adjusting arm 11. An activity shaft part 13 is installed between the upper end of the adjusting arm 11 and the push block 14. The upper end of the adjusting arm 11 is rotationally connected with the push block 14 through the activity shaft part 13. The lower end of the adjusting arm 11 is a rotating structure with the adjustment seat 10. The adjusting arm 11 is distributed in a cross shape with respect to the symmetry center line of the push block 14, and the adjusting arm 11 and the rotating shaft 12 cooperate with each other to form a rotating structure;
[0023] Specifically, through the setting of the adjustment seat 10, the adjustment seat 10 is composed of a hydraulic cylinder 16, an adjusting arm 11, and a push block 14. And the use of the activity shaft part 13 makes the adjusting arm 11 form a rotating structure with both the push block 14 and the adjustment seat 10, and moves in cooperation with the lifting of the hydraulic cylinder 16, which is convenient to push the push block 14 to move up and down. The push block 14 will push the trolley 1, and then lift one side of the trolley 1 to maintain the balance and stability of the trolley 1, and then adjust the center of gravity of the trolley 1.
[0024] The bottom of the trolley 1 is fixedly connected with a telescopic rod 15. The outside of the lower end of the telescopic rod 15 is movably sleeved with a support frame 5. The telescopic rod 15 is fixedly connected with the bottom of the trolley 1. The trolley 1 is movably connected with the support frame 5 through the telescopic rod 15;
[0025] Specifically, the bottom of the trolley 1 is fixedly connected with the telescopic rod 15. The telescopic rod 15 and the inside of the support frame 5 are in a sleeved structure, which is convenient for the telescopic rod 15 to move up and down inside the support frame 5, facilitating the movement of the trolley 1 and improving the flexibility of the trolley 1.
[0026] Wheels 4 are installed on both sides of the bottom of the base 3. A driver 6 is installed inside the wheels 4. A push handle 2 is fixedly connected to one side of the trolley 1. A telescopic cylinder 7 is installed inside the support frame 5, and a mounting frame 8 is installed below the telescopic cylinder 7. An auxiliary wheel 9 is movably installed inside the mounting frame 8. The mounting frame 8 and the base 3 form a rotating structure through a shaft member. The mounting frame 8 and the auxiliary wheel 9 are in one-to-one correspondence and a total of four groups are provided;
[0027] Specifically, the auxiliary wheel 9 is installed on the mounting frame 8. The auxiliary wheel 9 cooperates with the wheels 4 to roll, driving the trolley 1 to move. The mounting frame 8 and the base 3 are movably connected. When the telescopic cylinder 7 presses down, the mounting frame 8 will tilt and then contact the ground to help the trolley 1 stop, facilitating loading and unloading when parking.
[0028] The working principle of the present utility model is as follows: When using the present utility model, put the items into the trolley 1. When the placement position and weight of the items are uneven, the heavier side of the trolley 1 will press down, causing the trolley 1 to tilt. Use the hydraulic cylinder 16 to push the push block 14 upward, thereby lifting the trolley 1 and making the unbalanced side of the trolley 1 balance with the other side to adjust the center of gravity. When the push block 14 is lifted by the hydraulic cylinder 16, the adjusting arm 11 moves in cooperation with the rotation of the shaft member and the rotating shaft 12, and moves up and down in cooperation with the push block 14 to support the push block 14. Secondly, when the trolley 1 moves upward to adjust the center of gravity, the telescopic rod 15 at the bottom of the trolley 1 will move upward inside the support frame 5. Thirdly, the wheels 4 installed at the bottom of the base 3 roll by the drive of the driver 6, and cooperate with the auxiliary wheels 9 installed on the mounting frame 8 to drive the trolley 1 to move. When it is necessary to stop, after stopping the driver 6, the telescopic cylinder 7 presses down one end of the mounting frame 8, and one end of the mounting frame 8 will contact the ground downward, increasing the friction with the ground, thereby stopping the auxiliary wheels 9 and the wheels 4 from continuing to move and helping the trolley 1 to stop, facilitating loading and unloading when parking.
[0029] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
