Detailed Description

The technical solution of the present invention is further explained with reference to the drawings of the specification.

As shown in fig. 1-3, the utility model discloses a handcart of loading and unloading turnover case, including automobile body 1, the 1 front end of automobile body is U style of calligraphy opening for provide the space of placing for turnover case 9. The rear end of the vehicle body 1 is provided with a pushing handle, and the bottom of the vehicle body is provided with four wheels. The two sides of the opening of the vehicle body 1 are provided with clamping mechanisms for clamping the turnover box 9, the clamping mechanisms are rectangular frames 7 with the front ends opening corresponding to the size of the turnover box 9, the existing turnover box 9 generally has a sealed cover body, and the edge of the cover body extends out of the vehicle body of the turnover box 9, so the two sides of the rectangular frames 7 can be provided with handrails 8, the handrails 8 rise upwards, and the turnover box is jacked up from the lower part of the edge of the cover body of the turnover box. The clamping mechanism can also be a clamping mechanism which can be changed according to the size of the box body in the prior art, such as a mechanical arm capable of adjusting the clamping position.

The lifting mechanism is arranged on the vehicle body 1 and is a rocker member which is hinged on the vehicle body and can rotate around a hinged point and has a fixed included angle, and the rocker member is connected with the clamping mechanism and is used for driving the clamping mechanism to ascend and descend. The rocker member is a double-arm member, but may have other numbers of rocker members. Both arms component is first connecting rod 2 and the second connecting rod 3 that is fixed contained angle, and the one end and the fixture of first connecting rod 2 are connected, and the other end is articulated with automobile body 1 and is used for making second connecting rod 3 drive first connecting rod 2 around the pin joint and rotate. The included angle between the first connecting rod 2 and the second connecting rod 3 is an obtuse angle, and specifically may be 95 to 130 degrees, or may be other angles. The two double-arm components are arranged at two sides of the rear end of the vehicle body 1 respectively, the second connecting rods 3 in the double-arm components at two sides are connected through a cross beam, the second connecting rods 3 are longer than the first connecting rods 2, so that more labor is saved through the lever action formed between the two double-arm components, when one ends of the second connecting rods 3 are pressed down, the other ends of the first connecting rods 2 can rise, and therefore the clamping mechanisms hinged with the first connecting rods 2 rise, and finally the turnover box 9 clamped by the clamping mechanisms is lifted off the ground. First connecting rod symmetry respectively between fixture and both sides automobile body 1 articulates there are two sets ofly, can increase the holding power to fixture, and specific quantity can set up as required.

The vehicle body 1 is provided with a pedal assembly which is connected with the rocker arm assembly and used for controlling the rocker arm of the rocker arm assembly. The pedal assembly includes a horseshoe groove for pedaling, and may be other shapes of structures for pedaling, such as a pedal. The horseshoe groove and the rocker arm component are connected through a connecting piece 10, the connecting piece 10 is a U-shaped connecting piece which is fixed on a cross beam between the second connecting rods 3 on two sides of the vehicle body 1 and has an opening facing the cross beam, and the connecting piece 10 can also be of other structures capable of realizing connection.

As shown in fig. 4 to 5, the vehicle body 1 is provided with a locking mechanism for locking and resetting the lifting mechanism. The locking mechanism comprises a stop hook 4 hinged at the rear end of the vehicle body 1 and used for fixing the lifting mechanism, and a pull rod 5 for driving the stop hook 4 to rotate around a hinged point so as to enable the lifting mechanism to be separated from the stop hook 4. One side of the connecting piece 10 extends into the blocking hook 4, and the connecting piece 10 is fixed by the groove of the blocking hook 4 so as to fix the rocker arm component. The stop hook 4 is connected with a pull rod 5, the pull rod 5 is fixed on a push handle, the top of the push handle is hinged with a handle, and the handle is hinged with the pull rod, so that the pull rod is lifted or pressed down through the shaking of the handle, and the connecting piece 10 is released or fixed from the stop hook 4.

The working process is as follows: as shown in fig. 1, the utility model is firstly pushed to the position where the turnover box 9 is located in the opening of the vehicle body 1, and then the second connecting rod in the rocker arm component is pulled downwards, so that the handrail of the clamping mechanism is pressed against the cover body edge of the turnover box, as shown in fig. 2. Finally, the horse shoe groove is stepped down, the second connecting rod 3 is continuously pressed down, the second connecting rod 3 drives the first connecting rod 2 to slowly lift the turnover box 9 clamped by the rectangular frame 7 and the handrail 8 upwards, as shown in fig. 3, the second connecting rod 3 is pressed down to the position shown in fig. 3, the first connecting rod 2 is at a vertical angle, one side edge of the connecting piece 10 extends into the groove of the blocking hook to lock the rocker arm component, so that the turnover box is stably fixed at the opening of the automobile body, and the bottom of the turnover box is separated from the bottom surface. Finally, the cart is pushed to transport the turnover box 9 to a designated position. When the turnover box is unloaded, the handle 6 is lifted at first, the connecting piece 10 is separated from the stop hook, the locking is released, the second connecting rod drives the connecting end of the first connecting rod and the clamping mechanism to descend, and therefore the fixed turnover box 9 stably descends to the ground, and the turnover task is completed.
