[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] like Figure 1-3As shown, this utility model is a handcart with an adjustable push handle height, including a cart platform 1. Wheels 2 are installed at the four corners of the bottom of the cart platform 1. The wheels 2 are self-locking swivel wheels. Adjustable posts 3 are installed on the left and right sides of the rear of the upper surface of the cart platform 1. A sliding groove 31 is provided on the rear side of the adjustable post 3. The adjustable post 3 is arc-shaped, and the sliding groove 31 extends from top to bottom through the adjustable post 3. The adjustable post 3 serves to position and enclose the adjustable post. A push handle 5 is movably engaged within the sliding groove 31. The push handle 5 is n-shaped, and its vertical rod is inserted into the sliding groove 31. The lower end of the push handle 5 can move up and down along the sliding groove 31, thereby allowing the handle to be moved through the groove. The height of the push handle 5 is adjusted by adjusting the distance between the lower part of the push handle 5 and the adjusting post 3. An anti-slip sleeve 51 is fitted onto the center of the top of the push handle 5, and a positioning hole 52 is provided at the bottom of the push handle 5. The positioning hole 52 is located at the bottom of the two vertical rods of the push handle 5, and each vertical rod has at least three positioning holes arranged symmetrically at equal intervals. The number of positioning holes 52 indicates the height adjustment level of the push handle 5. The length of the adjusting post 3 is greater than or equal to the length of the two vertical rods of the push handle 5. A baffle 4 is attached to the lower part of the push handle 5. The baffle 4 is a material stop plate, with a flat center and curved sides, and is attached to the two vertical rods at the bottom of the push handle 5 for material stopping. It is detachable. A connecting rod 6 is movably mounted on the rear end of the vehicle platform 1 via a movable pin 64. The connecting rod 6 is U-shaped, and the lengths of its two vertical plates are equal to those of the adjusting column 3. The front end of the horizontal bar of the connecting rod 6 is movably connected to the vehicle platform 1 via the movable pin 64. The movable pin 64 is respectively installed on the left and right sides of the lower horizontal bar of the connecting rod 6 near the vehicle platform 1, and its outer end is movably inserted into a locking block, with the end of the locking block fixedly connected to the vehicle platform 1. The two vertical plates of the connecting rod 6 correspond to the positions of the sliding groove 31, and the top of the connecting rod 6 is close to the top of the adjusting column 3, ensuring that the maximum height of the push handle 5 can be adjusted. A foot pedal 6 is provided at the middle of the bottom end of the connecting rod 6. 1. The bottom end of the pedal 61 is connected to the vehicle plate 1 via a torsion spring 63, so that when the outer end of the pedal 61 is stepped on, the movable pin 64 can be rotated, and the torsion spring 63 is compressed. The upper front end of the connecting rod 6 is connected to a locking pin 62. The outer end of the locking pin 62 passes through the positioning hole 52 and is inserted into the slide groove 31. By locking the locking pin 62 into different positioning holes 52, the position of the push handle 5 can be locked. When the locking pin 62 is not inserted into the positioning hole 52, the torsion spring 63 is always in a compressed state. When the end of the locking pin 62 contacts the positioning hole 52, it will be inserted into the positioning hole 52 under the action of the spring force, thus completing the locking of the push handle 5.

[0019] Working principle: When the height of the push handle 5 needs to be adjusted, step on the pedal 61. Stepping on the pedal 61 will drive the connecting rod 6 to rotate backward at a certain angle around the movable pin 64, thereby allowing the locking pin 62 to disengage from the positioning hole 52. At this time, pulling the push handle 5 with one hand will move the push handle 5 to the desired position. Then, release the pedal 61, and the pedal 61 will be reset under the action of the torsion spring 63. Then, gently press the push handle 5 so that the locking pin 62 can be locked into the nearest positioning hole 52, thus locking the position of the push handle 5.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
