Description
Technical field
This utility model relates to the optimization design of a kind of quadropods, be specifically related to a kind of amphiarthrosis crutch, it is to avoid uses the limitation factor of crowd and the shakiness that lands that causes, and can play a supporting role to greatest extent.
Background technology
According to the aging society standard of the current international practice, more than 60 years old population ratio exceedes the 10% of total population, and over-65s population ratio exceedes the 7% of total population, referred to as aging society.Nowadays China's aged tendency of population is extremely serious, according to data in November, 2010, and more than 60 years old old people of China reaches 1.78 hundred million, accounts for the 13.2% of population, over-65s old artificial 1.19 hundred million, accounts for the 8.87% of total number of persons.Address prediction analysis is pointed out, China aging population in 2014 will break through and within 200,000,000,2025, reach 300,000,000, and China is running entrance aging society.The healthy problem of old people more can not be ignored.Show according to the work report of " the international handicapped and elderly's rehabilitation nursing technology of China and the auxiliary implement exhibition " held in Shanghai for 2010, participate in the crowd of exhibition, concern to auxiliary implement reaches the 29.14% of all products sum, visible, old people has great demand to assistor.The optimization of this quadropods is designed mainly for old people.Traditional quadropods, owing to using the factor (use crowd mostly is old man, and handicapped crowd) of crowd, easily causes landing of crutch unstable in use.The performance that can make crutch by optimization after being designed is more perfect.Either concave-convex road surface or smooth road surface, can make self center of gravity of crutch keep more steady, can be that use crowd provides stability greatly；Telescopic mounting is adapted for different height crowd use simultaneously.Crutch is made to more conform to need the demand of crowd by above optimization.
Utility model content
The design of this crutch includes Arm of walking stick, support bar, micromotion mechanism and Walking stick base.Wherein Walking stick base copies the most commonplace four safe foot schemes, and the retractor device of comparative maturity is used in the design of expansion link, it is easy to the height of regulation crutch, allows this crutch be applicable to more crowd.Crutch total length: 81.5----86.5cm.(inquiry data results shows, this scope is suitable for the crowd of 150 185cm heights and uses), micromotion mechanism includes crutch ball pin, outer shroud, half cincture block, crutch ball seat and screw.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of amphiarthrosis crutch, including Walking stick base, crutch handgrip and support bar, described crutch handgrip is connected with support bar upper and lower side respectively with Walking stick base, it is characterized in that: described support bar lower end is connected by micromotion mechanism with Walking stick base, described micromotion mechanism includes the crutch ball pin being located at support bar end, it is located at the crutch ball seat of Walking stick base upper end, and it is dismountable partly around block, described half forms a spherical inner chamber accommodating crutch ball pin around block and crutch ball seat, described crutch ball pin uses matched in clearance with spherical inner chamber, the Impact direction making crutch points to the direction of force, strengthen the stability that crutch contacts with ground.
As improvement, described micromotion mechanism is provided with outer shroud, is provided with screw thread in described outer shroud, and described half is equipped with, around block and crutch ball seat outer surface, the external screw thread matched with outer shroud, and described outer shroud will partly be fixed around block and crutch ball seat entirety by screw thread.
As improvement, described support bar includes upper support bar and lower support bar, it is connected by retractor device between described upper support bar and lower support bar, described retractor device includes the upper expansion link being connected with upper support bar, be connected with lower support bar lower expansion link and rotate twisting ring, described upper expansion link and lower expansion link use sleeve connection, the described twisting ring that rotates is used for fixing expansion link with lower expansion link relative to position, it is easy to the height of regulation crutch, is applicable to the crowd of different height.
As improvement, described support bar is ± 6 ° relative to crutch ball seat fine motion scope, makes crutch can play the effect of support to greatest extent.
As improvement, described crutch handgrip is the S type meeting palm curve, allow user use comfortable, the bottom of described Walking stick base is provided with four feet, uses four foot Scheme Security, reliable.
The beneficial effects of the utility model are:
1, the effect of micromotion mechanism is to increase the stability that crutch contacts with ground, makes crutch can play the effect of support to greatest extent.Fine motion scope is ± 6 °, ball head device uses matched in clearance, the Impact direction making crutch points to the direction of force, can effectively tackle rough road surface, stable support is provided for user (handicapped old man or people with disability), it is different from traditional crutch, relies solely on battle foot and have a certain degree with ground shape, adapt to irregular concave-convex road surface.Therefore micromotion mechanism is while providing out color stability, can extend the service life of crutch.
2, the internal structure of micromotion mechanism so designs is to install for convenience, half cincture block is fixed by screws on crutch ball seat, and form a spherical inner chamber with crutch ball seat, crutch ball pin is placed in spherical inner chamber, ball head device uses matched in clearance, by outer shroud from the downward cincture in the upper end of expansion link, and the while of being threaded connection, stationary half, around block, crutch ball pin and crutch ball seat, allows crutch enter fine motion state.
