Abstract

A steel wire type electric hinge mechanism comprises an upper hinge, an upper door shaft sleeve, a lower hinge and a lower door shaft sleeve. An upper door shaft of the upper hinge is rotatably installed on the upper door shaft sleeve, and a lower door shaft of the lower hinge is rotatably installed on the lower door shaft. The hinge mechanism further comprises an upper limiting block, a steel wire torsion spring and a lower limiting block, and the upper limiting block and the lower limiting block are both fixedly connected with a door casing. The upper limiting block is fixedly connected with the upper door shaft sleeve, an inserting slot of a steel wire upper elbow is arranged on the lower portion of the upper limiting block, the lower limiting block is fixedly connected with the lower door shaft sleeve, and an inserting slot of a steel wire lower elbow is arranged on the upper portion of the lower door shaft. An upper elbow of the steel wire torsion spring is inserted into the inserting slot of the steel wire upper elbow, and a lower elbow of the steel wire torsion spring is inserted into the inserting slot of the steel wire lower elbow. The steel wire type hinge mechanism requires few components, is simplified in structure, convenient in assembling operations and low in cost.

Description

Wire type elastic hinge mechanism

Technical field

The utility model belongs to elastic hinge.

Background technology

The linkage of door has a variety of patterns, and hinge coaxial line is up and down arranged; The up and down different axis of hinge are arranged, utilize the centre-of gravity shift pattern that automatically resets; Also have a variety of can be the elastic hinge of door auto-closing, the technological deficiency that existing various elastic hinge mechanism exists: component are more, structure is comparatively complicated, assembly manipulation is cumbersome, cost is higher.

Summary of the invention

The deficiency more for the component that overcome existing elastic hinge mechanism, that structure is comparatively complicated, assembly manipulation is cumbersome, cost is higher, the utility model provides the wire type elastic hinge that a kind of component are less, structure is comparatively simplified, assembly manipulation is more convenient, cost is very low mechanism.

The utility model solves the technical scheme that its technical problem adopted:

A kind of wire type elastic hinge mechanism; Comprise upper hinge, to the doorstep axle sleeve, hinge and Xiamen axle sleeve down, the last door-hinge of said upper hinge is installed in rotation on to the doorstep on the axle sleeve, and the following door-hinge of said following hinge is installed in rotation on the axle sleeve of Xiamen; Said linkage also comprises upper limit position block, steel wire torsion spring and lower position block; Said upper limit position block all is fixedly connected with door shell with lower position block, and said upper limit position block is fixedly connected with said axle sleeve to the doorstep, and said upper limit position block bottom has elbow slot on the steel wire; Said lower position block is fixedly connected with said Xiamen axle sleeve; Said down door-hinge top has elbow slot under the steel wire, and elbow is inserted on the said steel wire in the elbow slot on the said steel wire torsion spring, and elbow is inserted under the said steel wire in the elbow slot under the said steel wire torsion spring.

Further, spool is installed in said upper limit position block and the lower position block outside.

Further again, said steel wire torsion spring is a steel wire, and two of said steel wire is equipped with elbow, on the said steel wire of the aspect ratio of said elbow under elbow slot and the steel wire elbow slot long.

Further, on the said steel wire under elbow slot and the steel wire width of elbow slot bigger than the steel wire diameter of steel wire torsion spring.

The technical conceive of the utility model is: because down hinge is fixed on and does not rotate on the casing, the following elbow that therefore inserts the steel wire in the hinge door-hinge slot down can not rotate; Because upper limit position block is fixed on the door shell, the last elbow that therefore inserts the steel wire in the upper limit position block slot so steel wire has just produced a torque, after the external force of opening the door is cancelled, forces door to be shut automatically along with door just rotates together again.

The beneficial effect of the utility model mainly shows: component are less, structure is comparatively simplified, assembly manipulation is more convenient, cost is very low.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

With reference to Fig. 1～Fig. 3, a kind of wire type elastic hinge mechanism comprises upper hinge 1, axle sleeve 2, hinge 9 and Xiamen axle sleeve 8 down to the doorstep; The last door-hinge of said upper hinge 1 is installed in rotation on the axle sleeve 2 of calling; The said following door-hinge of hinge 9 down is installed in rotation on the Xiamen axle sleeve 8, and said linkage also comprises upper limit position block 3, steel wire torsion spring 4 and lower position block 7 and spool 5, and said upper limit position block 3 all is fixedly connected with door shell 6 with lower position block 7; Said upper limit position block 3 is fixedly connected with said axle sleeve 2 to the doorstep; Said upper limit position block 3 bottoms have elbow slot on the steel wire, and said lower position block 7 is fixedly connected with said Xiamen axle sleeve 8, and said door-hinge top down has elbow slot under the steel wire; Elbow is inserted on the steel wire in the elbow slot on the said steel wire torsion spring 4, and elbow is inserted under the steel wire in the elbow slot under the said steel wire torsion spring.When elbow rotated with door on the said steel wire torsion spring, because elbow is inserted in play under the steel wire on hinge door-hinge top fixedly in the elbow slot under the said steel wire torsion spring, said steel wire torsion spring just produced moment of torsion, forced to reset.

Said upper limit position block 3 is installed spool 5 with lower position block 7 outsides.Said steel wire torsion spring 4 is a steel wire, and two of said steel wire is equipped with elbow, on the said steel wire of the aspect ratio of said elbow under elbow slot and the steel wire elbow slot long.On the said steel wire under elbow slot and the steel wire width of elbow slot more bigger than the steel wire diameter of steel wire torsion spring.

The assembling process of present embodiment is following: its assembling process is such: overlap earlier 3 of upper limits, spool 5, lower position block 7 and put in the door shell 6 into; Fixing with upper limit position block 3 with self-tapping screw then the axle sleeve 2 of calling, door shell 6; Put into the steel wire torsion spring again, fix Xiamen axle sleeve, door shell and lower position block with self-tapping screw; Go into door pocket in the upper hinge that is fixed on the casing again; Aim at the steel wire slot on the following hinge door-hinge the following elbow of steel wire torsion spring at last, change an angle (pretightning force) to following hinge then and be fixed on the casing, just accomplished the assembling process of door.

The course of work of present embodiment is: because down hinge is fixed on and does not rotate on the casing, the following elbow that therefore inserts the steel wire in the hinge door-hinge slot down can not rotate; Because upper limit position block is fixed on the door shell, the last elbow that therefore inserts the steel wire in the upper limit position block slot so steel wire has just produced a torque, after the external force of opening the door is cancelled, forces door to be shut automatically along with door just rotates together again.
