Accompanying drawing explanation
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model；
Fig. 2 is the structural representation of handrail latch segment.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are only used for
Bright this utility model rather than limit scope of the present utility model, after having read this utility model, art technology
Personnel all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As it is shown in figure 1, a kind of wheelchair knob armrest locking device, including locking bed 1, handrail latch segment 2, knob
Spanner 3.Locking bed 1 is arranged on the vehicle frame of wheelchair, is used for laying handrail.On locking bed 1 horizontally and vertically on direction
It is respectively provided with a through hole, in order to install handrail latch segment 2 and knob spanner 3.Handrail latch segment 2 is installed on locking bed
In vertical through hole on 1, its upper end is connected to the handrail tube of wheelchair armrest.Knob spanner 3 is by pad 4, spring
5, in stop nut 6 is installed on the horizontal through hole of locking bed 1.
As shown in Figure 1 and Figure 2, handrail latch segment 2 and knob spanner 3 are respectively equipped with breach 1, breach 28,
Breach 1 is hemispherical indentation, and its radius is less than the radius of breach 28 place cylinder.When breach 1, breach 28
Institute is towards in opposite direction, and when i.e. breach 1 is relative with breach 28, both match in " ten " font, now handrail locking
Block 2 and knob spanner 3 are in the state unclamped.When breach 1, breach 28 are consistent towards direction, and breach 1 is just
Can stick the cylinder of breach 28 reverse side, now handrail latch segment 2 and knob spanner 3 are in the state of locking.This reality
Using locking mode, close and firm does not haves rocks, and dismounting is the most more convenient, not only adds the peace of use
Quan Xing, also improves comfort.
