Description
Technical field
The present invention relates to field of furniture, and in particular to switching mechanism and furniture.
Background technology
At present, turnover table on the market is mostly using locating pin structure, and when desktop horizontal direction is locked using positioning pin, is made
Latch-release is carried out with steady brace or spanner, the function of turnover table top is then realized, is in lock timing position after desktop overturning
90°。
Switching mechanism is the key that realize turn over function, and the major defect of existing switching mechanism is：
(1) it is a great inconvenience in fact in the use of steady brace or spanner, user can only change oneself according to product
Use habit reduces likability of the user for product；
(2) without fixing and limiting structure after overturning, there is very big hidden danger, the desktop stress being connect with switching mechanism easily turns back water
Prosposition is put, situations such as being susceptible to desktop damage, table frame damage or crush user.
Invention content
The present invention is in view of the above-mentioned problems, overcome at least one deficiency, it is proposed that the overturning that can be automatically locked after overturning
Mechanism and furniture.
The technical solution that the present invention takes is as follows：
A kind of switching mechanism, including：
Fixed seat is provided with the first position limiting structure and the second position limiting structure in the fixed seat；
Rotating turret is rotatably installed in fixed seat；
Locating piece is unfolded, is movably arranged in rotating turret, expansion locating piece includes, for the first position limiting structure coordinating, making
Rotating turret is positioned at the first positioning region of position of organizing work；
Locating piece is folded, is elastic component, is movably arranged in rotating turret, locating piece is folded and includes tying with the second limiting
Structure coordinates, and rotating turret is made to be positioned at the second positioning region of folding work position；
Control assembly is movably arranged in rotating turret, for driving expansion locating piece and folding locating piece movement, is being unfolded
During working position, the first positioning region is made to be detached from the first position limiting structure, at folding work position, the second positioning region is made to be detached from the second limiting
Structure；
Dynamic clamping head and quiet clamping head, in rotating turret, for when control assembly is not by external force, resetting control assembly.
Rotating turret, by the cooperation of the first positioning region and the first position limiting structure, can make rotating turret when organizing work
Position of organizing work is positioned at, rotating turret will not be rotated by external force, when needing to be switched to folding work position from position of organizing work,
It only needs to pull control assembly, expansion locating piece can be driven by control assembly and fold locating piece and moved, first is fixed at this time
Position portion is detached from the first position limiting structure, and rotating turret can turn folding, and control assembly is no longer when rotating turret turns to setting position
It is acted on by external force, under the action of dynamic clamping head and quiet clamping head, control assembly, expansion locating piece and folding locating piece movement reset, at this time
Second position limiting structure and the second positioning region coordinate, and rotating turret are made to be positioned at folding work position, rotating turret will not be rotated by external force；
When needing to adjust to when organizing work, it is only necessary to pull control assembly, by control assembly can drive expansion locating piece with
Locating piece movement is folded, the second positioning region is detached from the second position limiting structure at this time, and rotating turret can rotate expansion, when rotating turret is unfolded
In it is horizontal or basically horizontal when (in organizing work position), control assembly is no longer acted on by external force, in the work of dynamic clamping head and quiet clamping head
Under, control assembly, expansion locating piece and folding locating piece movement reset, the first positioning region and the cooperation of the first position limiting structure,
Rotating turret can be made to be positioned at position of organizing work.
During practice, switching mechanism can be used for the needs such as furniture overturning structure on, such as turnover table, Tipping-up chair or
Overturn bed etc..In use, it is generally necessary at least 2 groups of switching mechanisms, the rotating turret phase of turnover panel and each switching mechanism
To fixation, in this way, when rotating turret rotates, panel can be made also to rotate together, when rotating turret positioning is fixed, panel also positions fixation
Firmly.
The switching mechanism of the application by the cooperation of the second position limiting structure and the second positioning region after overturning, realizes limit
Position positioning function after rotating turret is made to go to fixed angle, excessively will not bring damage to panel or other component because of overturning or make
Furniture overturns due to mass centre changing after overturning, improves product stability, extends the service life of product；The overturning of the application
Mechanism can be automatically into lock-out state after overturning so that rotating turret will not outer masterpiece with suddenly under turn out, to user
Safety bring guarantee.
In one embodiment of the invention, the fixed seat include slide plate and be arranged on flat face both sides and interval set
The vertical plate put, two vertical plates are located at one end of slide plate, and the one end of slide plate far from vertical plate is provided with first limit
Bit architecture, when organizing work, rotating turret leans with slide plate, and the first positioning region coordinates with the first position limiting structure；It is described
Between rotating turret is rotatably installed in two vertical plates by rotation axis, there are two second position limiting structures, is symmetricly set on two
On a vertical plate.
By setting slide plate, when organizing work, the contact area of rotating turret and fixed seat can be increased, structure by
Power is more preferable；Two spaced vertical plates make it possible to set two the second position limiting structures, when overturning working position, rotating turret
It can preferably position.
At folding work position, angle between rotating turret and slide plate can be 60 °~90 °, it is preferred that for 60 °~
75 °, preferred angle is not easy to make to collide with other component with the fixed panel of rotating turret.
In one embodiment of the invention, first position limiting structure is the first groove, has first to lead on the rotating turret
Hole, first positioning region are latch hook, and latch hook is pierced by the first through hole.
In one embodiment of the invention, second position limiting structure is the second groove, has second to lead on the rotating turret
Hole, second positioning region are outer male structure, and at folding work position, second positioning region is pierced by rotation by the second through-hole
Frame stretches into corresponding second groove.
