Technical Field

The utility model belongs to the technical field of the lock, concretely relates to take flexible rotation of steel ball and lock handle device that resets.

Background

The handle resetting means of most locks on the market at present can appear about fixed back, do not swing about, because handle fixation nut can not beat and sticiss to extremely, sticis the back because of handle fixation nut, handle lock body welt and handle reset block can hug closely after sticising together, the handle will use big power when twisting with the hand, the handle can not reset when the pine hand resets, so most lock handle now, it can not compress tightly to compress tightly the fixation nut above the reset block, leave the space, make it become flexible and let the handle pass through reset spring and can let the handle twist open back automatic re-setting, such device can let the lock installation back handle have not hard up, influence the quality and the feeling of whole lock.

In the era of continuous innovation of technology, for example, patent No. 200420102297.4, the name "door lock handle bidirectional reset mechanism" discloses a door lock handle bidirectional reset mechanism, which comprises a lock surface 1, an A reset plate 2, an A spring 3, a turn 4 connected with a handle, a B reset plate 5 and a B spring 6. The two-way initial reset is realized by the restoring force action of the A spring 3 and the B spring 6, so that other new functions are realized. Still like patent number 200920148560.6, the name "lock handle, lock panel, reset component, lock handle assembly and lock" discloses protruding two lugs of establishing of cylindrical connecting end of lock handle, have a predetermined distance between the tip of two lugs and this connecting portion. Patent No. 201420850490.X, the name "a two-way reset type lock handle device" discloses a two-way reset type lock handle, has set up the shifting block and two-way torsional spring that reset in the handle pivot, has realized the function that all can self-reset after the handle two-way rotation, convenient and practical. Patent No. 201820159591.0, the name "installation spanner of intelligence lock tool to lock handle reduction torsion spring" discloses an installation spanner of intelligence lock tool to lock handle reduction torsion spring, its characterized in that: the handle comprises a handle body, wherein the handle body comprises an insertion end inserted on a door lock panel, the insertion end of the handle body is provided with a convex column for driving the handle reset torsion spring to be screwed, and the convex column is abutted against the free end of the handle reset torsion spring. The defect that above patent technique exists lies in handle lock body because of the space is little, fails to solve the lock body handle and resets the back, and the handle is not loose problem.

Disclosure of Invention

The utility model provides a take the nimble rotatory and lock handle device that resets of steel ball based on the not hard up problem that appears of handle after the lock body resets, its steel ball enables the rotatory flexibility of lock handle, and the handle can not swing, does not hinder the handle yet and resets.

The steel ball rotary mechanism is characterized in that steel balls are placed in a spinning seat of the steel ball rotary mechanism, the steel balls are locked corresponding to a spinning steel ball fixing piece, and the steel ball fixing piece is covered; the reset mechanism is composed of a reset block connected with a torsional spring and a reset gasket.

The spinning seat of the steel ball rotating mechanism is in a perforated trapezoid shape; the bottom of the steel ball washer is provided with a steel ball washer.

The steel ball of the steel ball rotating mechanism and the fixed piece are provided with at least more than three steel ball holes.

The handle reset block of the reset mechanism is provided with a limit block for handle rotation; the handle reset sheet is provided with a symmetrical torsion spring fixing block at the edge and a shaft hole at the center.

The reset gasket of the reset mechanism is provided with a buckled boss and a shaft hole for sleeving the square shaft.

Advantageous technical effects

The utility model relates to a take nimble rotatory and lock handle device that resets of steel ball has solved the handle and can not swing, does not hinder the handle yet and resets. And, still solved the lock body after the handle resets, the problem that the handle is not loose, made its handle intelligence lock product quality more reliable and practical.
