Specific embodiment:
The utility model can be implemented in the following way:
As shown in Figs. 1-3: the utility model includes determining base 1, motivation body 2 and linked component 3 to form.
It is described to determine base 1 and be fixed on doorframe.The motivation body 2 includes that engine-bed 21, cover board 22 and cam elasticity compress
Mechanism 23.The engine-bed 21 is equipped with sideslip slot 211 and perpendicular sliding slot 212；It includes laterally that the cam elasticity, which compresses mechanism 23,
Sliding block 233, longitudinal sliding block 234, cam 231, spring 232, damper 235, cam connecting shaft 236 and damper connecting shaft 237,
The transverse slider 233 is mounted in the sideslip slot 211 of engine-bed 21, and the longitudinal sliding block 234 is mounted on the perpendicular of engine-bed 21
In sliding slot 212, the cam 231 is articulated in engine-bed 21 by cam connecting shaft 236, and the spring 232 presses on up and down
Between two longitudinal sliding blocks 234,235 both ends of damper pass through damper connecting shaft 237 respectively and are hinged on upper and lower two longitudinal cunnings
In the damping slot 2341 of block 234；The cover board 22 is fixed on engine-bed 21, and the motivation body 2 is mounted on door-plate.
The linked component 3 includes linked block 31, interlocks fork 32, interlocking lever 33, shaft 34, determine base connecting shaft 35, is horizontal
To sliding block connecting shaft 36, interlock fork connecting shaft 37, engine-bed connecting shaft 38, interlocking lever connecting shaft 39 and space washer 30.It is described
31 one end of linked block base 1 is determined hingedly with described by shaft 34；33 one end of interlocking lever is by determining base connecting shaft 35 and determining machine
Seat 1 is hinged, and 33 other end of interlocking lever is hinged by transverse slider connecting shaft 36 and transverse slider 233；32 one end of fork are interlocked to pass through
It interlocks fork connecting shaft 37 and 31 other end of linked block is hinged, interlock 32 other ends of fork and pass through engine-bed connecting shaft 38 and engine-bed 21
Hingedly, it is hinged by interlocking lever connecting shaft 39 and 33 intermediate ends of interlocking lever that 32 intermediate ends of fork are interlocked, above-mentioned two parts being hinged
Between separated with space washer 30.
Door is started turning from closing to motivation body 2 during opening, since each component of interaction relation also rotates with it.Turn
Interlocking lever 33 drives transverse slider 233 to slide along sideslip slot 211 during dynamic, and transverse slider 233 is deflected with moving cam 231, convex
231 deflection of wheel forces longitudinal sliding block 234 to move downward along perpendicular sliding slot 212, to constantly squeeze spring 232, supports cam elasticity
The constantly accumulation of energy of press mechanism 23.When door opening angle is 90o(± 15o) when, cam elasticity compresses 23 decrement of mechanism and reaches most
Greatly, cam elasticity compresses the no longer accumulation of energy of mechanism 23.
When door from 90o(± 15o) continue to when 180 ° of unlatchings (or when door from 180 ° to 90o(± 15o) close when), it is convex
The horizontal distance of wheel 231 and 234 contact point of longitudinal sliding block is equal to zero, and 231 smooth rotation of cam, hinge itself, which will not generate, appoints
What turning moment, so within this range, if do not influenced by external force, door can position in any position.
When door is closed to 90o(± 15o), cam elasticity compresses mechanism 23 and starts to release energy, and cam 231 starts partially
Turn, motivation body 2 is made to start to rotate backward；Each component starts to reset, and damper 235 can slow down the reset speed of cam 231 at this time,
To slow down the reset speed of transverse slider 233；Due to interaction relation, motivation body 2 rotates backward speed and is forced to reduce, to make
Door in 90o(± 15o) within close when have the effect of self-closing buffering.
For the requirement for adapting to different occasions, the damper 235 can set one or more, the cam elasticity
One or more can be set by compressing mechanism 23.
