With the elongated hole 51 for facilitating inserted link 61 to be inserted into arc groove 32, the upper end cooperation of guide post 614 is connected with the second circlip 615, turns
It is provided with being connected to the outer end of elongated hole 51 on disk 5 and is used to that guide post 614 to be driven to move inward so as to insert after the rotation of turntable 5
Bar 61 is detached from the arcuate socket 52 of arc groove 32, and arcuate socket 52 is gradually curved inward by 51 one end of elongated hole;By using this knot
After structure, when the inner wall in inserted link outer end and arc bump offsets, guide post can be moved inward along elongated hole, when inserted link snaps onto
When in arc groove, guide post can be displaced outwardly along elongated hole, so, inserted link be enabled to be inserted into arc groove, be realized
Locking to retaining mechanism and fixing seat;Resetting-mechanism includes the torsional spring 7 being sleeved in turntable 5 and support base 41 between bottom,
Torsional spring 7 for driving turntable 5 to rotate counterclockwise, fix by one end of torsional spring 7 and the lower end surface of turntable 5, the other end and support base 41
Interior bottom fix;After by using this structure, after handle mechanism rotates clockwise turntable, when handle mechanism is detached from turntable
When, turntable can reset under the action of torsional spring;First that the upper end insertion for torsional spring 7 is provided on the lower end surface of turntable 5 inserts
Hole 53 is provided with the second jack 415 of the lower end insertion for torsional spring 7 on the interior bottom of support base 41;By using this knot
After structure, the fixing intensity of torsional spring Yu turntable and support base can be improved;Handle mechanism includes rotationally being threaded through on cover board 42
Shaft 81 in the middle part of end face, the threaded upper ends of shaft 81 are connected with handle 82, are provided on the upper surface of turntable 5 round table-like
Protrusion 53, the lower end of shaft 81 are provided with when shaft 81 is pressed down for covering the cover 811 being attached to outside protrusion 53, protrusion 53
If periphery wall on be provided with arterial highway in circumferentially distributed sawtooth 54, be provided on the internal perisporium of cover 811 identical as sawtooth 54
Quantity and for the tooth socket 812 that engage with sawtooth 54,81 outer cover of shaft between handle 82 and cover board 42 is equipped with for driving
Fixed handle 82 and shaft 81 move up so that cover 811 is detached from the second spring 83 of protrusion 53;After by using this structure, instantly
When pressure handle is attached to cover set outside protrusion and makes tooth socket and engagement, it can be driven by rotating clockwise handle
Turntable rotates clockwise, and after turntable rotates clockwise, guide post can move in arcuate socket, so, enables to insert
Bar is detached from arc groove, so as to realize the unlock to retaining mechanism and fixing seat;Several are provided in bottom plate 21 in circumferential
The bolt hole 25 of distribution is provided with a pair of of counter sink 34 on the interior bottom of fixing seat 3;By the setting of bolt hole, can pass through
Bottom plate is easily fixed on doorframe by screw, by the setting of counter sink, can be fixed to bottom plate conveniently by screw
In door body;The one end of connecting rod 1 far from hinged seat 2 is fixed by bolt 12 and support base 41;It, can after by using this structure
Improve the fixing intensity of connecting rod and support base;In using the present invention, first when it is required that retaining mechanism and fixing seat are locked
First pivot link and retaining mechanism enter retaining mechanism in fixing seat, enter the process of fixing seat in retaining mechanism
In, the inclined-plane on inserted link can cooperate with the inner wall of arc bump to be oriented to, and inserted link can be extruded inward, and guide post can be in elongated hole
In move inward, when inserted link is moved to arc groove position, inserted link can be inserted into arc under the action of the first spring
In shape slot, guide post can be displaced outwardly in elongated hole, after inserted link is inserted into arc groove, can be realized to retaining mechanism and
The locking of fixing seat can be realized the locking to door body after retaining mechanism and fixing seat locking;When it is required that retaining mechanism
When unlocking with fixing seat, handle is pressed down on, so that cover is provide with the outside of protrusion, and makes tooth socket and engagement, so
After rotate clockwise handle, handle is able to drive shaft, cover and turntable and rotates clockwise, and after turntable rotates clockwise, leads
Column can move in arcuate socket, so, inserted link be enabled to move inward, and after inserted link moves inward, inserted link can take off
From arc groove, so as to realize the unlock to retaining mechanism and fixing seat, then people pass through rotation lock mechanism and connecting rod,
After retaining mechanism removes fixing seat, connecting rod and retaining mechanism are continued to rotate, connecting rod and limited post is finally made to offset, this
Sample one realizes the unlock to door body;And in above process, when people do not push handle, even if handle is rotated,
Turntable will not rotate, and so, can be avoided the phenomenon that lock is misread in appearance.
It should be noted that in the embodiment above, as long as reconcilable technical solution can carry out permutation and combination, this
Field technical staff can be according to the exhaustive all possibility of mathematical knowledge of permutation and combination, and therefore, the present invention is no longer to permutation and combination
Technical solution afterwards is illustrated one by one, but it is understood that presently disclosed for the technical solution after permutation and combination.
It should be noted that listed above is only a kind of specific embodiment of the invention.It is clear that the invention is not restricted to
Upper embodiment, acceptable there are many deformations.
In short, all changes that those skilled in the art directly can export or associate from present disclosure
Shape is considered as protection scope of the present invention.
