Description
Technical field
The utility model relates to novel office table separation more particularly to a kind of rotational structures of folding seat.
Background technique
Folding seat is one of common office facility in minimized office place, by unfolding and folding the conversion of both of which,
Effectively save working space.Foldable structure used by folding seat currently on the market is relatively complicated, and manufacture and installation are difficult
Degree is big, some rotational structures directly adopt fixture block limiting rotating angle, and good appearance is affected.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of rotation knot of the simple and beautiful folding seat of structure
Structure.
To achieve the goals above, the utility model adopts the following technical solution:
The rotational structure of the folding seat includes inner rotary member and external rotary member, and the inner rotary member is connected by inner rotary member seat and core are fixed
Composition is connect, the slotted hole through inner rotary member seat and core is equipped in the middle part of inner rotary member, both ends are respectively connected with arcuation block, arc on the outside of core
Circle and slotted hole where the outer ledge of shape block is concentric, is equipped with the notch being recessed inwardly in the middle part of the external rotary member, notch it is outer
Profile is formed by connecting by two big arc side and two small arc side cross transition, and there are also short circular hole, short circular holes in the middle part of the external rotary member
Identical as oval bore dia, the circle where big arc side is identical as the circular diameter where the outer ledge of arcuation block, where small arc side
Circle it is identical as the outer edge diameter of core, core can be in notch inner rotation.
The rotational structure of the folding seat of the utility model can easily realize rotating function due to the above structure,
And it is not necessarily to extra supplementary structure, tailored appearance.
Detailed description of the invention
Fig. 1 is 1 structural schematic diagram of inner rotary member of the utility model embodiment；
Fig. 2 is 2 structural schematic diagram of external rotary member of the utility model embodiment；
Fig. 3,4 be the utility model embodiment core 12 and arcuation block 121 21 inner rotation of notch two states
Schematic diagram.
In figure: 1, inner rotary member；10, slotted hole；11, inner rotary member seat；12, core；121, arcuation block；2, external rotary member；20, short
Circular hole；21, notch；211, big arc side；212, small arc side.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs. 1-2, the rotational structure of the folding seat includes inner rotary member 1 and external rotary member 2, and inner rotary member 1 is by inner rotary member seat
11 and core 12 be composed of a fixed connection, in the middle part of inner rotary member 1 be equipped with through inner rotary member seat 11 and core 12 slotted hole 10, core 12
Outside both ends are respectively connected with arcuation block 121, and the circle and slotted hole 10 where the outer ledge of arcuation block 121 are concentric, in external rotary member 2
Portion is equipped with the notch 21 being recessed inwardly, and the outer profile of notch 21 is connected by two big arc side 211 and two small arc side, 212 cross transition
It connecing, there are also short circular holes 20 at 2 middle part of external rotary member, and short circular hole 20 is identical as 10 diameter of slotted hole, where big arc side 211
Circle is identical as the circular diameter where the outer ledge of arcuation block 121, the outer edge diameter of circle and core 12 where small arc side 212
Identical, core 12 can be in 21 inner rotation of notch.As shown in Figure 3-4, in rotation process, the outer edge of core 12 and small arc side
212 inner wall contact, the outer edge of arcuation block 121 are contacted with the inner wall of big arc side 211.
The rotational structure application method of this folding seat are as follows: by inner rotary member 1 and external rotary member 2 respectively with the interior outer support of folding seat
Bar is fixedly connected, and is passed through slotted hole 10 and short circular hole 20 with pin shaft and is fixed, while with the hands rotating inside and outside support rod, interior turn
Body 1 and external rotary member 2 relatively rotate, since the angle of big 211 limited length of arc side, rotation is limited in certain range
It is interior, it is ensured that the stability of chair.
The rotational structure of the folding seat of the utility model can easily realize rotating function, and be not necessarily to extra auxiliary knot
Structure, tailored appearance are particularly suitable for office and use.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
