Abstract
The utility model provides a U-type spring which is made of steel wires in a bending and folding mode. The U-type spring comprises a U-type spring front end U-type groove, a U-type spring steel wire front end, a U-type spring middle circular ring and a U-type spring steel wire back end. A U shape is overall formed by the U-type spring front end U-type groove, the U-type spring steel wire front end, the U-type spring middle circular ring and the U-type spring steel wire back end. According to the U-type spring, the lever principle is combined, and small force is acted at the U-type spring steel wire front end to enable the U-type spring steel wire back end to generate large thrust to enable parts at the U-type spring steel wire back end to horizontally shift.
Description
Technical field
The utility model belongs to a kind of electronic lock drive device, is specifically related to a kind of U-shaped spring.
Background technology
At present, the drive unit of a lot of electronic locks is still and adopts the gear train device, by rotating the horizontal movement that realizes corresponding component between a plurality of gears, but the identical and circular motion mutually of gear train transfers rectilinear motion to and can produce a large amount of frictional force, not only can each component of loss and motor, also can cause the limited operating life of battery in electronic lock to shorten, greatly affect the quality of electronic lock.
The utility model content
The problem that the utility model occurs in order to solve above-mentioned electronic lock drive device, provide a kind of U-shaped spring.
The technical scheme that the utility model is taked is: a kind of U-shaped spring is provided, it is made by the steel wire bending fold, described U-shaped spring comprises: annulus, U-shaped spring steel wire rear end in the middle of the U-shaped groove of U-shaped spring at front end, U-shaped spring steel wire front end, U-shaped spring, " U " shape of whole formation, and the brachium of this U-shaped spring steel wire front end is greater than the brachium of U-shaped spring steel wire rear end.This U-shaped spring is to realize the horizontal movement of two ends parts according to lever principle, the U-shaped groove of U-shaped spring at front end is enclosed within on parts, in the middle of U-shaped spring, two annulus are fixed on a fulcrum, U-shaped spring steel wire rear end is connected with another parts again, like this by the respective horizontal displacement that moves left and right to realize U-shaped spring steel wire rear end of U-shaped spring steel wire front end.
The utility model has the advantage of, this U-shaped spring utilizes the principle of lever to improve the drawback of original working gear, has reduced energy loss and mechanical friction, is conducive to extend the application life of each parts and battery in electronic lock, has improved operating efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1 is U-shaped spring described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
With reference to Fig. 1, the utility model is made by the steel wire bending fold, described U-shaped spring comprises: annulus 3, U-shaped spring steel wire rear end 1 in the middle of the U-shaped groove 4 of U-shaped spring at front end, U-shaped spring steel wire front end 2, U-shaped spring, " U " shape of whole formation, and the brachium of this U-shaped spring steel wire front end 2 is greater than the brachium of U-shaped spring steel wire rear end 1.The specific works mode is: the U-shaped groove 4 of this U-shaped spring at front end is enclosed within on a driver part, two annulus 3 in the middle of U-shaped spring are fixed on a fulcrum, again U-shaped spring steel wire rear end 1 is connected with another functional component, when driving the U-shaped groove 4 of U-shaped spring steel wire front end, the front end drive unit moves right, while making the horizontal movement to the right of U-shaped spring steel wire front end 2, according to lever principle, middle two annulus 3 of the U-shaped spring of take are fixed support, U-shaped spring steel wire rear end 1 can produce an active force left to the parts that are connected, and makes its horizontal movement left.On the contrary, along with the front-end driven device drives the counter motion left of the U-shaped groove 4 of U-shaped spring steel wire front end, make the horizontal movement left of U-shaped spring steel wire front end 2, and then make the parts horizontal movement to the right be connected with U-shaped spring steel wire rear end 1, realize like this left and right horizontal displacement of each parts.And, due to brachium do not wait design, the required driving force of U-shaped spring steel wire front end 2 is less than the thrust that U-shaped spring steel wire rear end produces, and has strengthened the action effect of this U-shaped spring.
Claims (2)
1. a U-shaped spring, this U-shaped spring is made by the steel wire bending fold, it is characterized in that, and it comprises: annulus, U-shaped spring steel wire rear end in the middle of the U-shaped groove of U-shaped spring at front end, U-shaped spring steel wire front end, U-shaped spring wholely form " U " type.
2. a kind of U-shaped spring according to claim 1, is characterized in that, the brachium of this U-shaped spring steel wire front end is greater than the brachium of U-shaped spring steel wire rear end.
