Description
Technical field
The present invention relates to the accessory of baggage container, relate in particular to the cushioning wheel structure of travel of suitcase.
Background technology
Now, there is on the market multi-form baggage container, when the appearance of these baggage containers is gone out to people, carry individual carry-on articles and provide great convenience.Owing to often all having placed heavier article in baggage container, therefore mention baggage container walk suitable effort and inconvenience.People are installed tugboat additional in the bottom of baggage container, and user can tow baggage container, have so just greatly alleviated the burden while going out, and walking is got up more convenient, lighter, has saved many muscle power.If run into uneven or while having the irregular surface states such as some little low-lying areas of pitting, dilatory baggage container can make the collision on castor and ground strengthen, and adds the weight of baggage container, will cause baggage container walking unstable, even the situation of castor fracture.All more complicated of the shockproof structure of existing castor, in using for a long time or being subject to greater impact, Castor structure is easy to damage or displacement, causes castor stuck or come off, thereby has reduced the reliability that baggage container uses.
Summary of the invention
The object of this invention is to provide and a kind ofly can effectively alleviate the vibrations that bumpy road surface causes, simple in structure, compact, the suitcase cushioning wheel structure of travel that reliability is high.
For achieving the above object, suitcase cushioning wheel structure of travel of the present invention comprises caster base, castor, trace and elasticity pressure-containing member, described caster base is fixed on the casing of suitcase, described castor is fixed on one end of trace by wheel shaft, the other end of trace is hinged on caster base, trace middle part is fastened on caster base by elasticity pressure-containing member, and elasticity pressure-containing member elastic force direction and trace are around pin jointed end direction of rotation.
Caster base of the present invention comprises two adapter plates and an adapter plate, two adapter plates are L-type and connect, adapter plate forms respectively hemi-closure space with two vertical connections of adapter plate, the hemi-closure space of caster base is connected towards the casing of suitcase and with casing, and the other end of trace is hinged on adapter plate.
The outside face of the adapter plate of caster base of the present invention is provided with the race of indent, and the wheel shaft of castor is positioned at the race of caster base, and the rolling surface of castor extends outside caster base.
On adapter plate of the present invention, the position of corresponding castor wheel shaft is provided with chute, and castor wheel shaft passes trace and is set in the chute of adapter plate, and castor wheel shaft is provided with axle bolt through one end of chute, and the diameter of axle bolt is greater than chute width.In the process of castor motion, wheel shaft slides in the chute of adapter plate, and the movement travel that chute defines castor while being subject to impacting has avoided wheel shaft miles of relative movement excessive and cause the damage of elasticity pressure-containing member.On the other hand, axle bolt is fixed on the position of castor and trace in the scope of being close to adapter plate, thereby has avoided trace to be subject to excessive side impacting force and be out of shape or damage, and has further improved the reliability of this Shockproof wheel.
Elasticity pressure-containing member of the present invention comprises push rod and spring, the projection at one end of push rod and trace middle part is hinged, the push rod other end is extended into by the hole on race sidewall in the hemi-closure space of caster base, push rod is positioned on the other end of hemi-closure space and is fixed with catch, the diameter of catch is greater than the aperture in hole, and push rod relative opening is free to slide; Described spring housing is located on push rod, on push rod, is provided with spring stop piece with the hinged one end of trace projection, and one end of spring leans on spring stop piece, and the other end of spring leans on race sidewall.Described push rod and trace are tangent around pin jointed end rotation direction.
Two Shockproof wheels of a baggage container operated by rotary motion, in the time running into bumpy road surface, the castor power that has certain impact, trace rotates, and further promotes push rod and moves to race sidewall.At this moment, spring will be subject to the extruding of spring stop piece and race sidewall and the elastic deformation of compressing occurs, thereby has effectively absorbed extraneous impulsive force.
Compared with prior art, Shockproof wheel of the present invention can absorb extraneous impulsive force effectively, and this cushioning wheel structure of travel is simple simultaneously, the compactness that cooperatively interacts, and reliability is high, durable in use, even long-term use is not fragile yet on bumpy road surface.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the schematic diagram of suitcase cushioning wheel structure of travel of the present invention;
Fig. 2 be suitcase cushioning wheel structure of travel of the present invention front view;
Fig. 3 be suitcase cushioning wheel structure of travel of the present invention back view.
Detailed description of the invention
As shown in Figures 1 to 3, suitcase cushioning wheel structure of travel of the present invention comprises caster base 1, castor 2, trace 3 and elasticity pressure-containing member 4, described caster base 1 is fixed on the casing of suitcase, described castor 2 is fixed on one end of trace 3 by wheel shaft 21, the other end of trace 3 is hinged on caster base 1, trace 3 middle parts are fastened on caster base 1 by elasticity pressure-containing member 4, and elasticity pressure-containing member 4 elastic force directions and trace 3 are around pin jointed end direction of rotation.
Caster base 1 of the present invention comprises two adapter plates 11 and an adapter plate 12, two adapter plates 11 are L-type and connect, adapter plate 12 forms respectively hemi-closure space 5 with two 11 vertical connections of adapter plate, the hemi-closure space 5 of caster base 1 is connected towards the casing of suitcase and with casing, and the other end of trace 3 is hinged on adapter plate 12.
