DETAILED DESCRIPTION

[0019] like Figure 1-2As shown, a stacker with a vibration reduction function comprises a chassis 1 and universal wheels 2, wherein the universal wheels 2 are arranged at the bottom of the base and are symmetrically distributed in pairs, and further comprises a shock absorbing component, wherein the shock absorbing component is arranged between the bottom of the base and the universal wheels 2.

[0020] like Figure 1-4 As shown, in order to better absorb shock and buffer the chassis 1 and prevent material from tipping over, the shock absorbing assembly includes a shock absorber 3, a fixed column 4, a slider 5, a square plate 6, a shock absorber 7, a telescopic rod 8, a cylinder 11, a top block 12, a cross column 13 and a passive block 14. The shock absorber 3 is fixedly installed at the bottom of the chassis 1, and the shock absorber 3 is symmetrically distributed. The fixed column 4 is fixedly connected to the bottom of the shock absorber 3. The outer wall of the fixed column 4 is sleeved with a spring 9. The slider 5 penetrates the fixed column 4 and is slidably connected to the fixed column 4. The lower end of the spring 9 is fixedly connected to the top wall of the slider 5. The square plate 6 It is fixedly connected between the opposite side walls of the slider 5, the shock absorber 2 7 is fixedly connected to the bottom wall of the square plate 6, the telescopic rod 8 is fixedly connected to the lower end of the shock absorber 2 7, the outer wall of the telescopic rod 8 is sleeved with a spring 2 10, the universal wheel 2 is movably connected to the lower end of the telescopic rod 8, the cylinder 11 is fixedly connected to the bottom wall of the chassis 1, and the cylinder 11 is symmetrically distributed, the top block 12 is fixedly connected to the top wall of the square plate 6, the cross column 13 passes through one end of the cylinder 11 and is slidably arranged in the cylinder 11, the passive block 14 is fixedly connected to one end of the cross column 13, and a spring 3 16 is fixedly connected between the inner wall of the cylinder 11 and one end of the cross column 13.

[0021] Among them, the top block 12 and the passive block 14 are both set in a trapezoidal shape, and a ball 15 is rolled on the outer wall of the passive block 14. The ball 15 is in contact with the outer wall of the top block 12. The trapezoidal shape design can facilitate the squeezing of the passive block 14 during the upward movement of the top block 12. The inner diameter of the cylinder 11 is set in a decreasing manner, which can limit the sliding range of the cross column 13.

[0022] During specific use, a corresponding stacker is installed on the top of the chassis 1. During the movement of the stacker, if the road surface is uneven, the universal wheel 2 applies pressure to the telescopic rod 8 and the spring 2 10 to deform the spring 2 10. After the telescopic rod 8 contracts, the square plate 6 drives the slider 5 to apply pressure to the spring 1 9. The deformation of the spring 1 9 causes the slider 5 to slide on the fixed column 4. During the upward movement of the square plate 6, the top block 12 simultaneously moves upward to squeeze the passive block 14. After the passive block 14 is stressed, it applies pressure to the cross column 13. The cross column 13 applies pressure to the spring 3 16 to deform the spring 3 16. The decreasing diameter inside the cylinder 11 limits the sliding range of the cross column 13. The setting of the shock absorber 1 3 and the shock absorber 2 7 can reduce the vibration frequency of the spring 1 9 and the spring 2 10. Through the above-mentioned shock absorption process, the chassis 1 can be better protected from shock absorption, thereby avoiding problems such as material dumping.

[0023] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
