Description

Technical Field

[0001] The utility model relates to the technical field of electric flat cars, in particular to a shock absorbing and buffering structure of an electric flat car. Background Art

[0002] Electric flat carts have the characteristics of simple structure, easy use, large carrying capacity, no fear of dirt or smashing, easy maintenance and long service life. They have become the preferred means of transportation for frequent short-distance transportation of heavy objects within factory buildings and between factory buildings.

[0003] Publication No. CN212049251U discloses a shock absorbing device for an electric flat car. The patent drives the internal threaded sleeve to rotate by means of a hexagonal knob, so that the screw is rotated into the internal threaded sleeve during the rotation process, thereby adjusting the length of the screw connected to the internal threaded sleeve, so that the shock absorbing spring can adjust the compression degree as the screw is adjusted, and the shock absorbing strength of the shock absorbing spring can be adjusted to suit different working environments and effectively improve the convenience of use. However, the patent still has the following problems in actual use:

[0004] By driving the internal threaded sleeve to rotate through the set hexagonal knob, the length of the screw connected to the internal threaded sleeve can be adjusted, so that the compression degree of the shock-absorbing spring can be adjusted as the screw is adjusted, which is convenient for adjusting the shock-absorbing strength of the shock-absorbing spring. When adjusting the shock-absorbing strength of the shock-absorbing spring, it is only adjusted through the hexagonal knob. After the adjustment, the user cannot ensure that the rotation angles of several hexagonal knobs are consistent, and the displacement of the screw cannot be guaranteed to be consistent. The shock-absorbing strengths of several shock-absorbing springs may be different, affecting the shock-absorbing and buffering effect.

[0005] A shock absorbing and buffering structure of an electric flat car is proposed to solve the above-mentioned problems. Utility Model Content

When adjusting the shock-absorbing strength of the shock-absorbing spring, the adjustment is only performed through the hexagonal knob. After the adjustment, the user cannot ensure that the rotation angles of several hexagonal knobs are consistent, and the displacement of the screw cannot be ensured to be consistent. The shock-absorbing strength of several shock-absorbing springs may be difficult to measure, which affects the shock-absorbing and buffering effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shock-absorbing and buffering structure of an electric flat car, comprising an electric flat car body and a loading platform, and two sets of rollers symmetrically arranged at the bottom of the electric flat car body;

The movable sleeve can drive the connecting rod between the mounting blocks to rotate while moving. After the connecting rod rotates, the movable block can be pushed to slide inside the movable groove through the connecting block, and then the damping rod and the second buffer spring can be squeezed, so that the loading platform can be further buffered. The buffer assembly can reduce the vibration of the loading platform during movement, ensuring that the goods on the loading platform will not be damaged, thereby improving the overall service life and practicality.
