Description
Technical field
The utility model relates to a kind of luggage idler wheels.
Background technique
The idler wheel of luggage is usually all to install idler wheel by support shaft on the rotation shaft supporting frame connecting with luggage at present
Runner, support shaft is all thinner, due to packet with idler wheel be usually slide rotational support, thinner support shaft be easy pair
Runner causes too fast abrasion so that support shaft and turning wheel interval increase, cause rotation failure, in addition, such as publication number
" roller for luggage component " disclosed in CN106274290A is the widely used roller form of current luggage, using double runner
Structure, since structure is complicated, the probability of failure is increased, and also increases the use and cost of manufacture of idler wheel.
Summary of the invention
The purpose of this utility model is that proposing a kind of luggage idler wheel, by increasing the diameter of support shaft, peace is simplified
Assembling structure increases the firmness of idler wheel, so that this idler wheel is i.e. durable, and has saved use and cost of manufacture.
To achieve the goals above, the technical solution of the utility model is: a kind of luggage idler wheel, including support shaft and turn
Wheel, for runner turning set in support shaft, a rotation bracing strut for connecting with luggage is fixed to the support shaft connection, wherein
The support shaft diameter is at least 2/5ths of runner diameter, and rotation bracing strut includes two support arms being oppositely arranged, branch
Support round tube hole is provided in brace, the support shaft is two semiaxis docking compositions, the axially external end difference of two semiaxis
It is provided with the blocker ring of protrusion, runner is inserted between two opposed support structures, the insertion on the outside of two support arms of two semiaxis
The support round tube hole of support arm by runner turning set in support shaft, semiaxis outboard end blocker ring be close to support arm be connected and fixed with
Support arm forms integral structure.
Scheme is further: described two semiaxis are that length is symmetry equivalent or asymmetric equal semiaxis, two semiaxis are logical
Cross mother-son mouth or spiral shell button docking composition support shaft.
Scheme is further: described two semiaxis are provided with central shaft hole.
Scheme is further: setting helps sliding sleeve between runner and support shaft.
Scheme is further: it is described help sliding sleeve be roller or the spin gaily decorated basket set either polytetrafluoro wear-resistant sleeve.
Scheme is further: the runner radial outside is provided with polyurethane rubber sleeve, the rolling surface of polyurethane rubber sleeve
It is arc surface.
The beneficial effects of the utility model are: simplifying mounting structure by the diameter for increasing support shaft, increasing idler wheel
Firmness, using on equivalent specifications luggage, this idler wheel is i.e. durable, and has saved use and cost of manufacture.
The utility model is described in detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the utility model integral outer structural schematic diagram；
Fig. 2 is the utility model schematic diagram of internal structure.
Specific embodiment
A kind of luggage idler wheel, as depicted in figs. 1 and 2, the luggage idler wheel include support shaft 1 and runner 2, runner 2
For turning set in support shaft 1, a rotation bracing strut 4 for connecting with luggage 3 is fixed to the support shaft connection, rotates bracing strut
4 be that a kind of nylon adds fiber material, and rotation bracing strut 4 can carry out 360 degree of rotation around shaft 401, different from traditional idler wheel,
In order to improve the intensity of support shaft, the support shaft diameter is at least 2/5ths of runner diameter, and support shaft diameter is at least
2/5ths of runner diameter can be under conditions of different runner diameters, and a preferred embodiment is described five/second is that
Runner diameter is equal to or more than under conditions of 50mm, such as the present embodiment runner diameter is 100mm, and support shaft design diameter is
44mm is fixed to the support shaft connection, rotary shaft support Design two 402 Hes of support arm being oppositely arranged as rotation bracing strut 4
403 are used to support rotation bracing strut 4, are provided with closed support round tube hole on support arm, due to support round tube hole be it is closed,
Therefore, in order to install runner, the support shaft is two docking compositions of semiaxis 101 and 102, and two semiaxis are that length is symmetry equivalent
Or asymmetric equal semiaxis, such as one and half axial lengths, another semiaxis be short.As shown in Fig. 2, two semiaxis by mother-son mouth or
Person's spiral shell button docking composition support shaft.It is outside in the axis of two semiaxis in order to be connected and fixed to form integral structure with rotation bracing strut 4
Side is respectively arranged with the blocker ring 101-1 and 102-1 of protrusion, and when installation, runner 2 is inserted into two 402 Hes of opposed support structure
Between 403, the support round tube hole of two semiaxis 101 and 102 insertion support arm on the outside of two support arms 402 and 403 is by runner
In support shaft, semiaxis outboard end blocker ring abutting support arm is connected and fixed by the way of bonding to be formed turning set with support arm
Integral structure.Fig. 1 illustrates the overall effect after installation.One of those half axial length, another semiaxis are short, it might even be possible to understand
It has been arrived at the blocker ring of another side protrusion substantially for the length of major semiaxis.
In fact, what support shaft 1 and runner 2 formed is exactly traditional bearing, support shaft 1 is the inner ring of bearing,
Runner is the outer ring of bearing；Wherein, support shaft can be solid, but in order to save material, the present embodiment is designed as such as bearing
Inner ring be equally it is hollow, therefore: described two semiaxis are respectively arranged with central shaft hole 103 and 104, in the premise of proof strength
Under, the diameter selection of central shaft hole is being the half for supporting shaft diameter.
Abrasion is reduced in order to guarantee that runner rotation is smooth, can choose the generally wear-resisting easy sliding material of support shaft, such as
Polytetrafluoro material, but certainly will increase cost in this way, for less cost, guaranteed sliding is smooth: runner and support shaft it
Between setting help sliding sleeve 5.The selection class of support shaft can thus be lowered, such as use general PVC or ABS plastic
Material.Wherein: it is described that sliding sleeve is helped to can be using the roller or spin gaily decorated basket set as traditional bearing, or opposite thin slice
Polytetrafluoro wear-resistant sleeve.
In embodiment: runner is general plastics, but anti-skidding in order to have the effect of runner, the runner radial outside
Rubber sleeve 201 is set, is polyurethane rubber sleeve, is a kind of thermoplastic polyurethane elastomer.Polyurethane rubber sleeve connects with ground
The rolling surface 201-1 of touching is axial arc surface.The polyurethane rubber sleeve is arranged using vulcanization in the present embodiment.
