It is complicated.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of automatic open-close mechanism.
The technical solution of the utility model is as follows: a kind of automatic open-close mechanism, comprising: fixing seat is set to the fixing seat
On rotatable parts, both ends connect respectively with the fixing seat and the rotatable parts spring spool, two fixed rotating shafts, with
An and movable rotation-shaft.The fixing seat is connect with the rotatable parts by a fixed rotating shaft, the fixing seat with it is described
One end of spring spool is passed through by another fixed rotating shaft connection, the other end of the rotatable parts and the spring spool
The movable rotation-shaft connection.
Further, the axle center of two fixed rotating shafts constitutes different shapes from the axle center of a movable rotation-shaft
Shape, the shape are respectively straight line or triangle.
Specifically, automatic open-close mechanism described in the utility model utilizes Triangle Principle, two fixing points, a dynamic point and
The side of one variable can be realized the automatic open-close of bracket or door etc.The rotatable parts pass through the spring spool
It is flexible to realize the process for automatically opening and being closed.When the rotatable parts in the closure state, described two fixations turn
The axle center of axis and the axle center of a movable rotation-shaft constitute a triangle.When the rotatable parts are opened to certain angle
After degree, the axle center of described two fixed rotating shafts and the axle center of a movable rotation-shaft form one on same straight line
Straight line.When the rotatable parts be in all be opened state when, the axle center of described two fixed rotating shafts with one
The axle center of the movable rotation-shaft can form a triangle again.The rotatable parts in the closure state, the spring spool
In spring be in nature elongation state, when opening, open the rotatable parts manually, at this time the spring in the spring spool
It is shortened by reduction length, when the axial group in the variable axle center of the movable rotation-shaft and two fixed rotating shafts is in line, at this time
Spring is compressed into most short in the spring spool, when the variable axle center of the movable rotation-shaft is higher than the axis of two fixed rotating shafts
When the straight line that the heart is linked to be, hand is unclamped, spring-return, the rotatable parts can automatically open under the drive of spring force to be needed
The position wanted.In the open state, the spring in the spring spool is also in nature elongation state to the rotatable parts,
When closure, the rotatable parts are turned off manually, the spring in the spring spool is shortened by reduction length at this time, when the activity
When the axial group of the variable axle center of shaft and two fixed rotating shafts is in line, spring is compressed into the spring spool at this time
It is most short, when the variable axle center of the movable rotation-shaft is lower than the straight line that the axle center of two fixed rotating shafts is linked to be, unclamp hand, bullet
Spring is replied, and the rotatable parts can be closed into the position of needs automatically under the drive of spring force.
Using the above scheme, the utility model automatic open-close mechanism can be realized display screen, bracket using Triangle Principle
Or the automatic open-close of door closure.Automatic open-close process is realized using flexible springs sleeve, structure is simple, occupies little space, and opens
Closing operation is simple and convenient, at low cost.
Detailed description of the invention
Fig. 1 is structural schematic diagram when the utility model automatic open-close mechanism is in closure；
Fig. 2 is structural schematic diagram when three axle center of the utility model automatic open-close mechanism are in same straight line；
Fig. 3 is structural schematic diagram when the utility model automatic open-close mechanism is in opening.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Please refer to Fig.1 to Fig.3, the utility model provides a kind of automatic open-close mechanism, comprising: fixing seat 1, be set to it is described
Connect respectively with the fixing seat 1 and the rotatable parts 2 spring spool 3, two of rotatable parts 2, both ends in fixing seat 1
Fixed rotating shaft 4 and a movable rotation-shaft 5.The fixing seat 1 is connected with the rotatable parts 2 by a fixed rotating shaft 4
It connects, the fixing seat 1 is connect with the spring spool 3 by another fixed rotating shaft 4.The rotatable parts 2 and the bullet
Spring casing 3 is connected by the movable rotation-shaft 5.The axle center in the axle center of two fixed rotating shafts 4 and a movable rotation-shaft 5
Different shapes is constituted, the shape is respectively straight line or triangle.The length of the spring spool 3 can be due to stretching and pressing
Contracting spring and change.The height in the axle center of the movable rotation-shaft 5 can change with the folding of the rotatable parts 2.This is automatic
Open-and-close mechanism structure is simple, installs easy to operate.
Specifically, automatic open-close mechanism described in the utility model utilizes Triangle Principle, two fixing points, a dynamic point and
The side of one variable can be realized the automatic open-close of bracket or door etc.Referring to Fig. 1 to Fig. 3, the rotatable parts
2 realize the process for automatically opening and being closed by the spring spool 3.When the rotatable parts 2 in the closure state, it is described
The axle center of two fixed rotating shafts 4 and the axle center of a movable rotation-shaft 5 constitute a triangle.When the rotation section
After part 2 is opened to certain angle, the axle center of described two fixed rotating shafts 4 and the axle center of a movable rotation-shaft 5 exist
On same straight line, straight line is formed.When the rotatable parts 2 are in the state being all opened, two fixations
The axle center of shaft 4 and the axle center of a movable rotation-shaft 5 can form a triangle again.The rotatable parts 2 are in closure
When state, the spring in the spring spool 3 is in nature elongation state, when opening the rotatable parts 2, first needs hand
Dynamic to open the rotatable parts 2, the spring in the spring spool 3 is shortened by reduction length at this time, when the movable rotation-shaft 5
When the axial group of variable axle center and two fixed rotating shafts 4 is in line, spring is compressed into most in the spring spool 3 at this time
It is short, when the straight line that the axle center that the variable axle center of the movable rotation-shaft 5 is higher than two fixed rotating shafts 4 is linked to be, unclamp hand, bullet
Spring is replied, and the rotatable parts 2 can automatically open the position of needs under the drive of spring force.At the rotatable parts 2
When opening state, the spring in the spring spool 3 is in nature elongation state, when needing to be closed the rotatable parts 2,
The rotatable parts 2 need to first be turned off manually, the spring in the spring spool 3 is shortened by reduction length at this time, when the activity
When the axial group of the variable axle center of shaft 5 and two fixed rotating shafts 4 is in line, spring is pressed in the spring spool 3 at this time
Be reduced to it is most short, when the variable axle center of the movable rotation-shaft 5 lower than two fixed rotating shafts 4 axle center be linked to be straight line when, pine
Hand, spring-return are opened, the rotatable parts 2 can be closed into the position of needs automatically under the drive of spring force.
In conclusion the utility model automatic open-close mechanism using Triangle Principle can be realized display screen, bracket or
The automatic open-close of door closure.Automatic open-close process is realized using flexible springs sleeve, structure is simple, it occupies little space, folding behaviour
Make it is simple and convenient, it is at low cost.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
