Detailed Description
The shock absorbing structure of the luggage of the present invention will be further described with reference to fig. 1.
The utility model provides a shock absorber structure of suitcase, includes fixing base 1, wheelset subassembly 6 and shock attenuation axle subassembly, characterized by: the shock-absorbing shaft assembly includes a rotation shaft 2 and an elastic member 3.
The wheel set assembly 6 comprises a base 61 and rollers 62 mounted on two sides of the base 61, the base 61 is provided with a guide block 611 protruding upwards, the lower side of the fixed seat 1 is provided with a guide sleeve 11 in guiding fit with the guide block 611, and the guide block 611 is provided with a mounting hole 5 penetrating through the upper surface and the lower surface of the base 61.
The upper end axial of pivot 2 is spacing to be fixed in fixing base 1 with the coaxial mounting hole of uide bushing 11, but the lower extreme mobile assembly is in the pilot hole 5 of wheelset subassembly 6 to and spacing position 53 that has the spacing pivot 2 of definite removal from pilot hole 5 in the pilot hole 5.
The elastic component 3 is sleeved on the rotating shaft 2, the upper end of the elastic component 3 abuts against the fixed seat 1 or the rotating shaft 2, and the lower end of the elastic component 3 abuts against the wheel set assembly 6, so that elastic support is formed for the fixed seat 1 and the rotating shaft 2.
With the above structure, the base 61 is in a suspended state, and no component is mounted on the lower side of the base 61, so that when the lower end of the rotating shaft 2 moves relative to the base 61, no interference is generated on the components in the wheel set assembly 6; simultaneously, the upper end of the rotating shaft 2 is fixed with the fixed seat 1, so that the arrangement of a reserved space between the fixed seat 1 and the luggage case is saved. In conclusion, the structural design of the invention is more reasonable and optimized, and the invention is convenient for production, assembly and use.
The embodiment is further configured as follows: the assembling hole 5 comprises a guide section 51 for axially and slidably assembling the rotating shaft 2 and a avoiding section 52 for accommodating the lower end of the rotating shaft 2 after moving downwards. The avoidance section 52 is configured to reserve a space for the lower end of the rotating shaft 2, and during the damping process, the lower end of the rotating shaft 2 enters the avoidance section and is hidden in the avoidance section. The arrangement of the avoiding section does not generate interference influence on any part, so that the structure is more reasonable compared with the structure in the prior art.
The embodiment is further configured as follows: the diameter of the guide section 51 is smaller than that of the avoiding section 52, so the limiting position 53 is a limiting step formed between the guide section 51 and the avoiding section 52, and the lower end of the rotating shaft 2 is provided with a lower everting riveting edge 22 capable of abutting against the limiting step. For structural strength, a spacer 7 is also fitted over the lower everting bead 22. Under this structure, when gasket 7 shifts up and leans on to spacing step, pivot 2 can't continue to rise, plays the spacing effect that rises to pivot 2.
Another embodiment of the ascending limit of the rotating shaft 2 is as follows: a limiting rod is inserted in the assembling hole 5, and the lower end of the rotating shaft 2 is provided with a limiting outer step or a limiting flanging. When the rotating shaft 2 ascends, the limiting outer step is abutted against the limiting rod, and the rotating shaft 2 cannot continuously ascend.
The embodiment is further configured as follows: the elastic part 3 is a tower-shaped spring. When the shock absorption is carried out, the tower-shaped spring can be compressed into a surface, and compared with a spring in the prior art, the axial distance occupied after the tower-shaped spring is compressed is obviously reduced, so that the reservation of the space between the wheel set assembly 6 and the fixed seat 1 is further saved, meanwhile, the distance between the fixed seat 1 and the wheel set assembly 6 is reduced, and the stability between the fixed seat 1 and the wheel set assembly 6 is improved; on the other hand, the tower-shaped spring has different stress at each section, namely, the stress is gradually increased, so that the tower-shaped spring is more stable in deformation and shock absorption.
The embodiment is further configured as follows: the spindle 2 has an outer step 23, against which the upper end of the tower spring bears. The upper end of the rotating shaft 2 is provided with an upper outward turning riveting edge 21, and an annular groove which is in axial limit fit with the mounting hole of the fixed seat 1 is formed between the outer step 23 and the upper outward turning riveting edge 21.
The embodiment is further configured as follows: the wheel set assembly 6 is provided with a metal rotary gasket 4 arranged at the upper port of the assembly hole 5, and the lower end of the tower-shaped spring is abutted against the rotary gasket 4. The upper end and the lower extreme of turriform spring support respectively and lean on outer step 23 and swivel washer 4, can promote wheelset subassembly 6 for fixing base 1 pivoted stability.
The embodiment is further configured as follows: the rotary washer 4 has a retaining wall 41. The enclosure wall 41 is able to confine the lower end of the tower spring within the rotary washer 7, ensuring rotational stability of the wheelset assembly 6.
