when the telescopic rod 224 moves upwards, one end of the shock-absorbing reinforcing rib 225 is fixed on the inner side of the hollow tube 222, and the other end of the shock-absorbing reinforcing rib is embedded into the telescopic rod 224, and as the middle parts of the shock-absorbing reinforcing ribs 225 are obliquely arranged, when being stressed, the shock-absorbing reinforcing ribs can bend inwards to form a bow-like structure, and the deformation is helpful for absorbing and dispersing the shock energy, so that the influence of the shock on the whole structure is reduced;
The engaging groove 2241 is configured to engage with the end of the shock-absorbing stiffener 225, so that when the shock-absorbing stiffener 225 deforms during the vibration, the engaging groove 2241 can provide a certain support and stability to prevent the shock-absorbing stiffener 225 from excessively deforming or falling off, and the engaging relationship is helpful to maintain the effectiveness and durability of the shock-absorbing stiffener 225 during the vibration.
In a preferred embodiment, a clamping groove 2241 is formed on the surface of the telescopic rod 224 and corresponding to each shock-absorbing reinforced rib 225, the lower end of the shock-absorbing reinforced rib 225 is embedded into the clamping groove 2241, the edge of the lower end of the clamping groove 2241 is provided with an arc chamfer, one side of the lower end of the shock-absorbing reinforced rib 225, which is close to the clamping groove 2241, is provided with an inclined surface 2252, and when the electric push rod 223 contracts to the output shaft, the lower end edge of the clamping groove 2241 is extruded with the inclined surface 2252, and the shock-absorbing reinforced rib 225 is separated from the abutting state with the clamping groove 2241;
When the output shaft of the electric push rod 223 pushes the caster 226 to protrude out of the lower end of the hollow tube 222, the shock-absorbing stiffener 225 is embedded into the locking groove 2241, when the output shaft of the electric push rod 223 retracts the caster 226 into the hollow tube 222, the edge of the lower end of the locking groove 2241 on the telescopic rod 224 is pressed against the inclined surface 2252 of the lower end of the shock-absorbing stiffener 225, due to the design of the inclined surface 2252, the shock-absorbing stiffener 225 starts to be separated from the abutting state with the locking groove 2241 when being pressed, and the caster 226 is gradually pulled back into the hollow tube 222 as the output shaft of the electric push rod 223 is further retracted, and the shock-absorbing stiffener 225 starts to be abutted against the outer side of the caster 226 due to the interaction between the inclined surface of the lower end of the shock-absorbing stiffener 225 and the surface of the caster 226 after being separated from the locking groove 2241, and this abutting state helps to provide additional support and stability when the caster 226 is retracted back into the hollow tube 222, and also helps to disperse and reduce vibration.
According to a preferred technical scheme, a shock absorption air bag 2251 is arranged in a shock absorption reinforcing rib 225, the shock absorption air bag 2251 extends along the outline of the shock absorption reinforcing rib 225, and two sides of the shock absorption reinforcing rib 225 protrude out of two sides of the shock absorption air bag 2251, wherein the shock absorption reinforcing rib 225 and the shock absorption air bag 2251 are in a fan-shaped structure, and one small-caliber end of the shock absorption reinforcing rib is arranged towards a telescopic rod 224;
Moreover, a space for deformation of the shock-absorbing air bags 2251 is formed between the inner side of the shock-absorbing reinforced rib 225 and the shock-absorbing air bags 2251, the space is arranged close to the outer side of the shock-absorbing air bags 2251, the shock-absorbing air bags 2251 are filled with air, and have certain elasticity and compressibility, when the shock-absorbing reinforced rib 225 is extruded or vibrated, the shock-absorbing air bags 2251 can absorb part of vibration energy, and the shock-absorbing air bags 2251 are filled in the shock-absorbing reinforced rib 225 to help to strengthen the overall structural strength of the shock-absorbing reinforced rib 225 through compression and expansion of the air;
when the shock-absorbing reinforcement 225 is compressed, the following changes occur:
Deformation and recovery, namely, the shock-absorbing reinforcing ribs 225 are deformed by pressure, particularly, the inclined parts of the shock-absorbing reinforcing ribs 225 are inwards bent, when the pressure is released, the shock-absorbing reinforcing ribs 225 try to recover to the original shape, and the shock-absorbing air bags 2251 also play a role in helping recovery in the process;
Compression and expansion of shock-absorbing bladder 2251 when shock-absorbing stiffener 225 is compressed, shock-absorbing bladder 2251 will also compress, absorb some of the shock energy, and when the pressure is released, shock-absorbing bladder 2251 will expand, helping shock-absorbing stiffener 225 return to its original state, which will prevent shock-absorbing stiffener 225 from permanently deforming or failing when it is over-compressed.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
