It should be understood that the structures, ratios, sizes, etc. shown in the drawings of the present specification are only used for matching with the contents disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any modification of the structures, changes of the ratio relationship or adjustment of the sizes should still fall within the scope of the present invention without affecting the functions and the achievable purposes of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

Referring to fig. 2, the utility model provides a chip box shallow of preventing transportation rupture of disc, including automobile body 1, chassis 2 and wheel 3, automobile body 1 is separated with chassis 2, links together through the bumper shock absorber, and wheel 3 installs below chassis 2, and the preferred universal wheel that is of wheel 3 makes things convenient for the shallow to turn to in the transportation. The automobile body 1 is located directly over chassis 2, and it has first bumper shock absorber 4 and second bumper shock absorber 5 to distribute between the two, and wherein first bumper shock absorber 4 is installed at the automobile body both ends, and the second bumper shock absorber is installed at the automobile body middle part, because the power that bears in the middle of is great, so the elastic damping of second bumper shock absorber 5 is greater than the elastic damping of first bumper shock absorber 4.

Referring to fig. 3, in an embodiment, six shock absorbers are distributed between a vehicle body 1 and a chassis 2, wherein two first shock absorbers 4 are respectively installed at two ends of the six shock absorbers side by side, two second shock absorbers 5 are installed at the middle of the six shock absorbers side by side, the first shock absorbers 4 installed at the two ends are close to the edge of the vehicle body, specifically, the four corners of the vehicle body are close to the present embodiment, the two second shock absorbers 5 are installed close to the center of the vehicle body, and the six shock absorbers are symmetrically distributed between the vehicle body 1 and the chassis 2. Wherein, the preferential cartridge bumper shock absorber that adopts of second bumper shock absorber 5 guarantees that the atress direction can not squint, and cartridge bumper shock absorber's upper end and automobile body 1 adopt the connected mode that can rotate relatively in the front and back direction, and cartridge bumper shock absorber upper end can rotate with the automobile body relatively in the front and back direction promptly, but does not have relative displacement, if articulated, lower extreme and chassis 2 fixed connection. The first shock absorber 4 can adopt a shock absorbing spring, the upper end of the shock absorbing spring is fixedly connected with the vehicle body 1, the lower end of the shock absorbing spring is fixedly connected with the chassis 2, the two ends of the spring are fixed, and the spring can move back and forth in the horizontal direction due to elasticity, or the upper end of the spring adopts a mode of abutting against the vehicle body; a tubular shock absorber can also be adopted, wherein the upper end of the tubular shock absorber is connected with the vehicle body 1 in a relatively rotating way and can rotate relatively in the front-back direction, such as hinging, and the lower end of the tubular shock absorber is fixedly connected with the chassis. This kind of upper end of bumper shock absorber and automobile body 1 swing joint, lower extreme and chassis fixed connection's mode can make chassis 2 fluctuate under the prerequisite that automobile body 1 remains stable, and automobile body and chassis can use the second bumper shock absorber to do the relative rotation of small range as the fulcrum moreover, increase the shock attenuation effect.

In other embodiments, the upper end of the second shock absorber may be fixedly connected to the vehicle body 1, the lower end of the second shock absorber may be rotatably connected to the chassis 2, and the mounting manner of the first shock absorber may be adjusted.

The utility model discloses a both ends still can be equipped with baffle 6 around this kind of prevent chip box shallow of transportation fragment's automobile body, 6 fixed welding of baffle are in the automobile body front and back end, the length of its upper and lower direction extends to below the chassis 2, because automobile body 1 separates with chassis 2, when meetting big shock, automobile body 1 is because inertia dashes forward probably to lead to automobile body 1 and chassis 2 to separate, damage the bumper shock absorber, it can prevent automobile body 1 and chassis 2 to separate to set up the baffle at the front and back end, reduce the impaired probability of bumper shock absorber. The rear end of the vehicle body 1 can be provided with a trolley handle 7, so that external force can be applied by workers conveniently.

Fig. 4 is a schematic view of the chip box cart for preventing transportation fragments of the present invention during transportation, wherein during transportation, when the cart encounters a large obstruction, the cart vibrates, and on one hand, since the cart body 1 is separated from the chassis 2, a transportation worker can directly apply an external force to the cart body 1 through the cart handle 7 to stabilize the cart body 1, thereby reducing the influence of chassis vibration on the cart body; on the other hand, as the shock absorber is arranged between the vehicle body 1 and the chassis 2, when the vehicle encounters a bumpy road section, the generated vibration energy is sequentially transmitted upwards through the wheels 3 and the chassis 2, and when the vibration energy passes through the shock absorber arranged between the vehicle body 1 and the chassis 2, the vibration energy from the chassis 2 can be effectively absorbed through the shock absorbing spring, so that the vibration energy is weakened, and meanwhile, a certain protection effect is achieved for the small handcart; and the second shock absorber 5 plays a role of supporting the vehicle body 1 in the whole structure, bear most of the weight of the vehicle body 1, the large elastic damping can not cause the vehicle body to deform when the vehicle body 1 is fully loaded, the first shock absorber 4 plays a role of auxiliary support, when the road surface has an obstacle, the chassis 2 compresses the first shock absorber 4 to float correspondingly by taking the second shock absorber 5 as a supporting point, if the elastic damping of the first shock absorber 4 is larger than that of the second shock absorber 5 or the elastic damping of the first shock absorber 4 is equivalent to that of the second shock absorber 5, the corresponding movement of the chassis can be blocked, and the shock absorption effect is reduced.

To sum up, the utility model discloses a chip box cart for preventing transportation of broken pieces, wherein a cart body is separated from a chassis and is connected together through a shock absorber, when the cart shakes due to road surface reasons, a transporter can apply force to enable the cart body to tend to be stable, and the influence on the cart body can be reduced due to the vibration of the chassis; the shock absorber can buffer the vibration of the vehicle body caused by the vibration of the chassis for many times on one hand, and can reduce the vibration caused by the deformation of the vehicle body when a person applies thrust to the cart on the other hand. The trolley can effectively reduce the risk of fragment and improve the transportation efficiency of chips. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
