Description
Technical field
It the utility model is related to air pressure rod field, more particularly to a kind of self-return air pressure rod.
Background technology
CN 201070144Y disclose a kind of lifting down resetting barometric stick, its main gas between the base and chair cushion of chair tool
Separately it is provided with intake valve in pressure bar, the inlet open is provided with air admission hole, and in being provided with rotary resetting element, the rotation in the air pressure rod
Turn involution element has upper and lower involution part respectively, and the upper and lower involution part has the convex being engaged in corresponding end face respectively
Portion and location indentations, and corresponding cunning guide face is formed in the positioning convex portion of upper and lower involution part and location indentations both sides:Thus,
So that it can continue to import air under normality from the air admission hole, chair cushion is made to keep the power risen, and when user takes
When on the chair cushion, the power of the rising is e insufficient to the upward lifting of the chair cushion person of being used in connection with, after user leaves chair cushion
The upward lifting of chair cushion is allowed by the lasting air inlet of air admission hole, and when the chair cushion lifting lofty perch, set rotation in the air pressure rod
Turn involution element, the corresponding sliding guide face guiding that be in contact of its upper and lower involution part can be utilized to rotate, treated between upper and lower involution part
After turning to positioning convex portion and the corresponding clip positioning of location indentations, you can allow chair cushion to keep to certain orientation position, now should
Chair cushion is also simultaneously positioned at highest height.
However, although above-mentioned air pressure rod can cause turning chair to automatically return to original position and automatically return to the effect of peak,
But its is complicated, cost is higher, and the seat at scene is needed to keep more neat in occasions such as meeting-place, bank, consultings
State, elevating function is not needed, but need the stand of seat to automatically return to original position, prior art can not meet these
Demand.
The content of the invention
For overcome the deficiencies in the prior art, present invention employs following technical scheme：
A kind of self-return air pressure rod, including outer tube, inner tube, said inner tube be partially disposed in the outer tube and with it is described outer
Pipe is slidably matched, and the bottom of the outer tube is installed with door, in addition to spring, rod member, upper return unit, lower return unit, described
One end of rod member is fixedly connected with the door, and the other end is extend into said inner tube, the upper return unit and the rod member
Upper end is fixedly connected, and the lower return unit is placed in below the upper return unit and is fixedly connected with said inner tube, under described
Spring is installed between the bottom of return unit and the door.
Further, interior survey is installed with bushing above the outer tube, and said inner tube and the bushing are slidably matched.
Further, the upper return unit and the corresponding end face of lower return unit have respectively the positioning convex portion that is engaged and
Location indentations.
Further, bearing is also equipped between the spring and the door, is also set between the bearing and the spring
There is bearing shim.
Further, the upper return unit is fixedly connected by the first straight pin with the rod member, and the lower return unit leads to
The second straight pin is crossed to be fixedly connected with said inner tube.
Compared to prior art, the beneficial effects of the utility model are：
1st, it is simple in construction, cost is low.
2nd, rod member is fixedly connected with door, and one end of rod member is fixedly connected with door, upper return unit and rod member upper end
It is fixedly connected, the lower return unit is placed in below the upper return unit and is fixedly connected with said inner tube, therefore air pressure rod
Overall height will not change.By the cooperation of upper return unit, lower return unit, spring, in use, air pressure rod can arbitrarily revolve
Turn, when not in use, air pressure rod automatic homing.
The invention will be further described with reference to the accompanying drawings and detailed description simultaneously.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is return unit and lower return unit cooperation schematic diagram on the utility model；
Fig. 3 is the structural representation of return unit on the utility model；
Fig. 4 is the structural representation of return unit under the utility model.
Embodiment
Embodiment：
As shown in figure 1, a kind of self-return air pressure rod, including outer tube 1, inner tube 2, said inner tube are partially disposed in the outer tube
In and be slidably matched with the outer tube, the bottom of the outer tube is installed with door 3, in addition to spring 4, rod member 5, upper return unit
6th, lower return unit 7, one end of the rod member are fixedly connected with the door, and the other end is extend into said inner tube, it is described on
Return unit is fixedly connected with the rod member upper end, and the lower return unit is placed in below the upper return unit and made with said inner tube
It is fixedly connected, spring is installed between the bottom of the lower return unit and the door.
Surveyed in above the outer tube and be installed with bushing 8, said inner tube and the bushing are slidably matched.
One embodiment of the present utility model, the upper return unit and the corresponding end face of lower return unit have phase respectively
The positioning convex portion 9 and location indentations 10 of cooperation.
