Embodiment
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
As shown in Figures 1 to 4, it is spacing to include armrest assembly 1, handrail for the automatic reset structure of the utility model stow-away arm rest
Handle 2, handrail positive stop 3, driving lever 4, pad 5, spring 6, chair framework 8, bearing pin 9, bearing pin stroke groove 10, armrest assembly
1st, handrail positive stop 3 is all locked on chair framework 8 by first screw 71, and one end of driving lever 4 passes through one second
Screw 72 is locked on chair framework 8, and driving lever 4 is provided with bearing pin stroke groove 10, bearing pin 9 pass through after bearing pin stroke groove 10 with handrail
Component 1 is fixed, and driving lever 4 is provided with pad 5 and spring 6, and spring 6 is enclosed on driving lever 4, pad 5 be located at one end of spring 6 with
Between bearing pin 9, the spacing handle 2 of handrail is enclosed on one end of handrail positive stop 3, and it is spacing that handrail positive stop 3 is provided with handrail
Block groove 11, in locking and the when of folding handrail positive stop groove 11 withstands driving lever 4.
Armrest assembly 1 is provided with a through hole 12, and one end of handrail positive stop 3 passes through through hole 12, through hole 12, this sample prescription
Just spacing and operation is carried out.
The side of armrest assembly 1 is provided with a regulating tank 17, and one end of handrail positive stop 3 is passed through after through hole 12 positioned at adjusting
Save in groove 17, so facilitate adjustable handrail positive stop 3 to be rotated down around the first screw, so control driving lever to withstand or depart from
Handrail positive stop groove.
The shape of cross section of driving lever 4 is ellipse, so reduces the friction of driving lever and base skeleton, makes stow-away arm rest
Use lighter.
Specifically, the bottom of armrest assembly 1 includes two protruding blocks 101, and the other end of driving lever 4 is located at two projections
Between block 101, bearing pin 9 is fixed with protruding block 101, so simple in construction, easy to use.
Operation principle of the present utility model is as follows：Driving lever is provided with bearing pin stroke groove, and bearing pin can be in bearing pin stroke groove
Interior slip, bearing pin stroke groove play position-limiting action to the shift position of bearing pin.Pad compresses bearing pin under the action of the spring, and bearing pin exists
Armrest assembly and chair framework is set to keep relative position in the presence of pad（It is in the lock state）, the driving lever top in locking
Firmly handrail positive stop groove, i.e. driving lever prop up handrail positive stop, and armrest assembly will not be rotated, and now stow-away arm rest is in
Lock-out state, now armrest assembly do not rotated because of the effect of people.When needing to fold, armrest assembly and driving lever can be rotating around the
One screw, the rotation of the second screw.Handrail positive stop can rotate around the first screw.One end of handrail positive stop is pulled downwards
Dynamic, the other end of handrail positive stop tilts, and handrail positive stop groove departs from driving lever, and armrest assembly is downward around the first screw
Rotation, can thus fold armrest assembly.Armrest assembly folds to a certain extent, the point of rotation, the driving lever of armrest assembly
The point of rotation and the axis of bearing pin be located on straight line, continue stow-away arm rest component, now, spring can produce one to bearing pin
Downward thrust, armrest assembly auto-folder, that is, realize and automatically reset；Opposite, armrest assembly is pulled afterwards can to a certain extent
Automatic-expanding, now, spring can produce a upward thrust to bearing pin, be achieved in that armrest assembly Automatic-expanding and locking,
Realize and automatically reset.
In summary, the utility model can automatically reset stow-away arm rest, and its stabilized structure is simple and quick, be adapted to
The ability to act inconvenience such as old man and children crowd uses.
Particular embodiments described above, to the technical problem, technical scheme and beneficial effect of solution of the present utility model
It is further described, should be understood that and the foregoing is only specific embodiment of the utility model, not
It is all within the spirit and principles of the utility model for limiting the utility model, any modification for being made, equivalent substitution, change
Enter, should be included within the scope of protection of the utility model.
