Above, keep most suitable sitting posture be it is necessary, it is all, it is necessary to which handrail height has regulatory function, to be adapted to different patients'
Stature, or suitable patient's different periods, the demand of different handrail heights.User is caused to change sitting posture at any time, handrail is necessary
There are the function of adjusting up and down, the particularly patient with hemiplegia, the requirement to handrail height is harsher.
, there is certain difficulty and risk in wheelchair above and below weakling, wheelchair up and down again after handrail is removed, handrail is not re-formed
Hinder, understand the difficulty and risk of wheelchair above and below substantially reduction.
At present, the wheelchair armrest lifting of in the market and disassembly mechanism, have hand wheel type and play two kinds of pin, and hand wheel type is consolidated
Determine mechanism and assemble and disassemble troublesome bothersome, the fixed mechanism shakiness of bullet pin, easily rock.
Utility model content
The technical problems to be solved in the utility model be in the market wheelchair armrest lifting and disassembly mechanism, have hand wheel type and
Two kinds of pin are played, the fixed mechanism assembly and disassembly trouble of hand wheel type is bothersome, and the fixed mechanism of bullet pin is unstable, easily rocks, to solve
Above mentioned problem, the utility model provides a kind of wheelchair armrest lifting disassembly mechanism and the wheelchair including the mechanism.
The purpose of this utility model is realized in the following manner：
A kind of wheelchair armrest lifts disassembly mechanism, including the guide pin bushing being arranged on wheelchair frame, and guide pin bushing upper end edge is square vertically
To offering groove I, the outside of guide pin bushing upper end is provided with anchor ear, guide pin bushing be internally provided with bushing, bushing be provided with guide pin bushing
The corresponding groove II of groove I, be provided with handrail conduit in bushing, the upper end of handrail conduit is connected with handrail.
Salient point is provided with the inside of the bushing.
The bushing is plastics or rubber.
The length of the handrail conduit is more than the length of guide pin bushing.
The shape of the handrail conduit, guide pin bushing and bushing is worked in coordination, and the cross section of handrail conduit is regular hexagon, side
Shape, rectangle, triangle, ellipse, Long Circle or circle.
A diameter of 10-45mm of the inscribed circle of the guide pin bushing cross section, the guide pin bushing length is 30-200mm.
A kind of wheelchair, including above-mentioned handrail lifting disassembly mechanism, handrail lifting disassembly mechanism are arranged on wheelchair armrest and wheel
Between seat base.
Relative to prior art, the utility model provides a kind of wheelchair armrest lifting disassembly mechanism, can fast assembling-disassembling help
The height of hand and adjustable handrail, enables to wheelchair armrest regulation to arrive the height for being adapted to user, and convenient use person sits from side
Upper wheelchair so that care-giver is lighter.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is guide pin bushing；2 be groove I；3 be anchor ear；4 be bushing；5 be groove II；6 be handrail conduit；7 be wheelchair armrest；8
It is wheel seat base.
Embodiment
As shown in Figure 1, a kind of wheelchair armrest lifting disassembly mechanism, including the guide pin bushing 1 being arranged on wheelchair frame, guide pin bushing
1 upper end vertically offers groove I 2, and the outside of the upper end of guide pin bushing 1 is provided with anchor ear 3, and guide pin bushing 1 is internally provided with bushing 4, lining
Be provided with the groove II 5 corresponding with the groove I 2 on guide pin bushing 1, bushing 4 on set 4 and be provided with handrail conduit 6, handrail conduit 6 it is upper
End is connected with handrail.
The setting of the groove II 5 on groove I 2 and bushing 4 on guide pin bushing 1 can cause anchor ear 3 to be in when locking state, guide pin bushing 1
Handrail conduit 6 can be tightly wrapped with bushing 4, prevents handrail conduit 6 from moving up and down.
The inner side of bushing 4 is provided with salient point, and the salient point set up can prevent handrail conduit 6 from being rotated in bushing 4.
Bushing 4 is plastics or rubber, and plastics or rubber bushing 4 can increase the friction of handrail conduit 6 and bushing 4
Power.
The length of handrail conduit 6 is more than the length of guide pin bushing 1.
The shape of handrail conduit 6, guide pin bushing 1 and bushing 4 is worked in coordination, and the cross section of handrail conduit 6 is regular hexagon, side
Shape, rectangle, triangle, ellipse, Long Circle or circle.
A diameter of 10-45mm of the inscribed circle of guide pin bushing cross section, guide pin bushing length is 30-200mm.
A kind of wheelchair, including above-mentioned handrail lifting disassembly mechanism, handrail lifting disassembly mechanism are arranged on wheelchair armrest 7 and wheel
Between seat base 8.
