The push rod11can be unlocked and locked by turning the locking handle27, making the adjustment process of the push rod11simpler and faster. The foldable support frame16facilitates the user to adjust the posture of the load-bearing rod12, making loading more convenient, and the cart body1can also be used in conjunction with the luggage3to increase the carrying space and meet user needs.

Specifically, the push rod11is U-shaped, and both sides of an inner wall of the push rod11are provided with a plurality of locking holes111; an inside of the beach wheel19is provided with a wheel hub191for connecting to the driving rod17.

In the embodiment, the number of locking holes111is set according to the adjustable height of the push rod11. The U-shaped push rod11has an integrated design and higher stability. The wheel hub191is used to support the beach wheel19, and the wheel hub191and the driving rod17are movably connected through a bearing, so that the beach wheel19rotates more smoothly.

Specifically, insides of both transmission handles21are provided with a movable hole22sleeved with the gear23; the two movable holes22are opposite to each other, and insides of the two movable holes22are respectively provided with a first gear rack24and a second gear rack25staggered from each other.

In the embodiment, with reference toFIG.3, the first gear rack24and the second gear rack25are respectively installed inside the two movable holes22. The first gear rack24and the second gear rack25are not only staggered front and back, but also staggered up and down. The gear23is relatively long and can be simultaneously matched with the first gear rack24and the second gear rack25.

Specifically, the first gear rack24and the second gear rack25are respectively meshed with a bottom and top of the gear23; one end of the transmission handle21away from the movable hole22is provided with a stabilizing plate211, and one side of the stabilizing plate211away from the transmission handle21is provided with an inserting rod28; one end of the inserting rod28away from the stabilizing plate211is movably inserted into an interior of one of the locking holes111, and one side of the stabilizing plate211away from the inserting rod28is provided with a support rib212.

In the embodiment, the first gear rack24and the second gear rack25are staggered up and down. When the gear23rotates, the first gear rack24and the second gear rack25will move in opposite directions. When the first gear rack24and the second gear rack25move, they will drive the two transmission handles21to move. When the transmission handle21moves, it will drive the inserting rod28to move synchronously. When the inserting rod28is inserted into the locking hole111, the position of the push rod11is locked; when the inserting rod28is out of the locking hole111, the push rod11can be moved up and down to adjust the height. After the adjustment is completed, the locking hole111is made identical to the inserting rod28. The locking handle27controls the gear23to rotate and drive the transmission handle21to drive the inserting rod28to be inserted into the locking hole111to complete the position locking. The stabilizing plate211is movably sleeved inside the cross bar13. The setting of the stabilizing plate211ensures the movement stability of the transmission handle21and does not cause front and rear deviation. The setting of the support rib212ensures the connection stability between the stabilizing plate211and the transmission handle21, and ensures the overall structural strength of the locking mechanism2.

Specifically, both sides of the cross bar13are provided with assembly holes132; one end of the gear23is provided with a positioning shaft26movably sleeved with one of the assembly holes132, and the other end thereof passes through the other assembly hole132and is provided with a locking handle27.

In the embodiment, after the positioning shaft26is sleeved with one of the assembly holes132, the position of the gear23can be limited, avoiding the left and right deviation of the gear23and ensuring the stability of the gear23during rotation. The gear23is rotated by the locking handle27to drive the first gear rack24and the second gear rack25. According to the rotation direction of the locking handle27, the relative movement or the opposite movement of the two transmission handles21is realized. When the two transmission handles21move relative to each other, the transmission handle21drives the inserting rod28at one end thereof to disengage from the inside of the locking hole111. When the two transmission handles21move away from each other, the transmission handle21drives the inserting rod28at one end thereof to be inserted into the inside of the locking hole111.

Specifically, both ends of the support frame16are fixedly provided with L-shaped positioning joints161; one end of the positioning joint161away from the support frame16is movably hinged to the load-bearing rod12, and both sides of the positioning joint161are provided with a plurality of connecting ribs1611.

In the embodiment, for the L-shaped positioning joint161, when the load-bearing rod12needs to be placed horizontally, the support frame16is flipped so that the corner position of the L-shaped positioning joint161clamps the load-bearing rod12, so that the support frame16can maintain a stable support for the load-bearing rod12. When the load-bearing rod12does not need to be placed horizontally, but needs to be lowered and tilted, the support frame16is flipped so that the positioning joint161is disengaged from the clamping of the load-bearing rod12, and the support frame16is flipped to be close to the bottom of the load-bearing rod12, so that the horizontal height of the load-bearing rod12can be lowered, which facilitates loading and reduces the collision between the support frame16and ground obstacles during movement. The setting of the connecting ribs1611ensures the structural strength of the positioning joint161and the stability of its connection with the support frame16.

Specifically, both ends of the load-bearing rod12are fixedly connected to the driving rod via a T-shaped first connecting piece122, and the load-bearing rod12is U-shaped; both ends of one side of the load-bearing rod12away from the driving rod17are provided with triangular reinforcing support pieces121; a top of the reinforcing support piece121is provided with a triangular support platform1211.
