Groove one；Guide sleeve is the external member for the up and down formula structure being movably arranged in guide post, and average mark is furnished on the outside of the external member
Multiple grooves two corresponding with groove one, the swing arm are made of two parallel fulcrum levers, and strut one end is movably arranged on recessed
On slot two, the other end is installed on a movable top foot；The telescopic rod is movably arranged on the groove one of annular element, the other end
It is movably arranged on swing arm；The adjuster is the rotation twisting part being mounted on guiding male screw.The invention is convenient for peace
Dress, operates with simple, conveniently, but there are problems that the stripped thread of load-bearing nut.
Utility model content
1. utility model technical problems to be solved
For overcome the problems, such as stripped thread occur there are load-bearing nut in the portable dress device of tyre of the prior art and cannot continuous load-bearing
The problem of, the utility model provides a kind of portable dress device of tyre.The utility model passes through the setting of secondary nut, when main nut and
When there is stripped thread failure between guiding screw rod, main nut can overlap one with secondary nut, and secondary nut load-bearing simultaneously rotates simultaneously, from
And achieve the purpose that continuous load-bearing.
2. technical solution
To solve the above problems, the utility model adopts the following technical solution:
A kind of portable dress device of tyre, including guiding screw rod, four-bar linkage, guide sleeve, fixing seat, support rod and double
Nut anti-slip thread mechanism, in which: the four-bar linkage includes upper connecting rod, shifting seat, supporting block, lower link and pin；Institute
State the outer rim that guide sleeve is socketed on double nut anti-slip thread mechanism；Periphery symmetrical expression point of the four-bar linkage in guide sleeve
Cloth, and guide sleeve side is connected to by shifting seat；The upper connecting rod and lower link are in upper and lower parallel relation, their one end is equal
It is fixed in the groove of shifting seat by pin；The other end passes through pin and is fixed in the groove of supporting block；The guide wire
After the top of bar is threadedly coupled with double nut anti-slip thread mechanism, lower part is fixedly connected after passing through fixing seat with fixing seat；The branch
Strut is equipped with four-bar linkage, and one end of support rod is fixed on the outer rim of fixing seat by pin, and the other end passes through
Pin is connected on lower link, solves the problems, such as that the strength in non-inflatable tyre process of expansion is unbalanced by four-bar linkage,
Reaching the portable dress device of tyre of solution by double nut anti-slip thread mechanism again there is technical issues that load-bearing nut occurred
Purpose.
Further embodiment, double nut anti-slip thread mechanism include be oriented to screw rod and be screwed onto guiding screw rod on main nut and
Secondary nut；The outer rim of the main nut is slidably socketed guide sleeve, is load-bearing nut, preset clearance between main nut and secondary nut；
When stripped thread failure between main nut and guiding screw rod, one is overlapped after the main nut and secondary nut stress, and rotate simultaneously,
To continue to drive guiding screw rod or more.
Further embodiment, secondary nut are located above main nut, and symmetrical card convex, the pair spiral shell is arranged in the top of main nut
The card slot and chuck that the setting of female end portion and card convex are correspondingly arranged rotate while realizing main nut and secondary nut after the two engagement.
Further embodiment, the top of main nut are provided with gear edge, and gear applies just guide sleeve on the top of guide sleeve
To pressure；It is provided with sliding equipment in the end of card convex and/or card slot, can be steel ball, lubricating graphite gasket etc., to avoid
Major and minor nut role is stuck when shifting.
Further scheme, sliding equipment include the steel ball in the circular trough and circular trough of the end of card convex, the steel
The diameter of pearl is slightly larger than the depth of circular trough, and steel ball, which can roll, drives major and minor nut mutually to slide, and prevents major and minor nut direct
Occur after contact stuck.
Further scheme, card convex, card slot and chuck are fan-shaped, be it is two or more, corresponding circular trough and
Steel ball be also it is two or more, quantity is more, and the engagement capability of the two is stronger, is less susceptible to stuck.
Further scheme, the top of supporting block are provided with the chuck of detent tire, dislocation when avoiding expanding.
Further scheme further includes handle, and the fixing end of the handle is plugged and fixed in gear along upper, operation side
Just, laborsaving；The bottom end of the supporting block and guiding screw rod has been respectively fixedly connected with gag lever post and locating rod, tire and wheel hub installation
When, positioning action is played, can be set in retractable structure, be adjusted correspondingly according to hub height.
Further scheme, secondary nut be it is two or more, top is identical with the apex structure of the main nut, reason
By can above be continued for load-bearing, it is only necessary to successively realize secondary-secondary, major-minor pair pair-pair ... of master-pair, major-minor-pair, major-minor etc.
The transfer of role.
A kind of operating method of portable dress device of tyre, step are as follows:
Step 1: tyre expansion: the supporting block of whole device being placed in the middle part of non-inflatable tyre, main nut rotates forward, main spiral shell
