Abstract

The lock body with freely parked lock core thumb wheel has the structure comprising one thumb wheel reset push sheet with one end connected to the casing and one elastic part to push the thumb wheel reset push sheet to swing towards the lock core hole.

Description

Lock body with lock core thumb wheel capable of being randomly parked

Technical Field

The invention belongs to a mechanical or electronic lock body.

Background

It is known that both mechanical and electronic locks are often provided with a knob for a person to rotate a lock cylinder in a house to open and lock the door. When the current lock body is rotated to drive the lock core to rotate and the thumb wheel pushes out or retracts the lock tongue, the thumb wheel on the lock core must be manually rotated to return to zero, otherwise, when the door is locked or opened at the back, the thumb wheel may lock the lock tongue. However, when people operate, people always stop rotating continuously when the people can open or lock the door in a habitual way, so that the thumb wheel is rotated to return to the zero position, and the situation that the thumb wheel is locked with the lock tongue sometimes happens, therefore, the applicant improves the current lock body.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides a lock body which is more reasonable in structure and more reliable in use, and the lock cylinder thumb wheel can be randomly parked, so that the thumb wheel is ensured to be automatically zeroed or reset to a state which does not influence the normal operation of the lock cylinder thumb wheel, and further the condition that a lock tongue is blocked and a door cannot be opened can not be caused.

In order to solve the technical problems, the invention adopts the following technical scheme:

the lock body comprises a shell, a lock tongue component and a lock cylinder, wherein the lock tongue component and the lock cylinder are arranged in the shell, the lock tongue component comprises a lock tongue and a lock tongue plate, a push-pull groove which can push the lock tongue plate to slide horizontally when the thumb wheel on the lock cylinder swings left and right is arranged on the lock tongue plate, and a thumb wheel push piece structure is arranged in the shell, and the lock body comprises a thumb wheel reset push piece with one end connected in the shell in a swinging way and an elastic piece which pushes the thumb wheel reset push piece to swing towards a lock cylinder hole.

In the improvement scheme of the lock body capable of randomly parking the lock cylinder thumb wheel, an arc-shaped groove taking a swinging point of the thumb wheel reset push piece as a circle center is arranged on the thumb wheel reset push piece, and a swinging guide post is arranged in the arc-shaped groove; the elastic piece is a torsion spring, and after the middle part of the elastic piece is sleeved in a spring fixing nail positioned on the shell, two ends of the elastic piece respectively prop against the swinging guide post and a push plate of the poking wheel reset push piece.

Compared with the prior art, the invention has the beneficial effects that: because the driving wheel push piece structure which is formed by the driving wheel reset push piece with one end connected in the shell in a swinging way and the elastic piece for pushing the driving wheel reset push piece to swing towards the lock core hole is arranged in the shell, when a person in a house drives the driving wheel to open the door or lock the door by rotating the knob each time, the driving wheel is reset to zero by not manually continuing to rotate the knob once the door is opened or locked, and the driving wheel is pushed away from the push-pull groove through the driving wheel reset push piece under the action of the elastic piece, so that the normal operation of the driving wheel is not influenced, the driving wheel is not stopped in the push-pull groove, and the dead bolt plate is possibly blocked, and the situation that the door cannot be opened or locked is avoided.

The invention is described in further detail below with reference to the attached drawings and detailed description:

[ detailed description ] of the invention

A lock body with a lock cylinder thumb wheel capable of being randomly parked, as shown in fig. 1 to 4, comprising a shell 1, a lock tongue assembly 2 and a lock cylinder 3, wherein the lock tongue assembly 2 comprises a lock tongue 21 and a lock tongue plate 22, a push-pull groove 221 which can push the lock tongue plate 22 to slide horizontally left and right when the thumb wheel 31 on the lock cylinder 3 swings left and right is arranged on the lock tongue plate 22, and the lock body is consistent with the current electronic and mechanical lock structure, and the difference is that: the shell 1 is provided with a thumb wheel push piece structure 4 which comprises an elastic piece 42 with one end connected with the thumb wheel reset push piece 41 in the shell 1 in a swinging way and pushing the thumb wheel reset push piece 41 to swing towards a lock cylinder hole, so that when a person in a house drives the thumb wheel 31 to open the door or lock the door by rotating the knob each time, as long as the door is opened or locked, the thumb wheel 31 is reset to zero (namely, the thumb wheel still falls into the push-pull groove) even if the person does not manually rotate the knob any more, as shown in fig. 1, under the action of the elastic piece 42, a force is always applied to enable the thumb wheel reset push piece 41 to swing towards the lock cylinder hole, and the thumb wheel 31 can be pushed away from the push-pull groove 221 through the thumb wheel reset push piece 41, so that the normal operation is not affected, as shown in fig. 2, the thumb wheel stays in the push-pull groove, and a dead lock tongue plate is not likely to be possibly dead, and the door is not opened or locked.

In this embodiment, an arc slot 411 with the swing point of the thumb wheel reset push piece 41 as the center of a circle is provided on the thumb wheel reset push piece 41, and a swing guide post 43 is provided in the arc slot 411 and is riveted or screwed on the housing; the elastic member 42 is a torsion spring, and after its middle part is sleeved in the spring fixing pin 44 located on the casing 1, two ends respectively prop against the swing guide post 43 and the push plate 412 of the thumb wheel reset push plate 41, as shown in fig. 3 and 4, so that an oblique pushing force is generated, so that the thumb wheel (whether the thumb wheel stays at the lower left corner or the lower right corner of the push-pull groove) can be pushed away, so as to avoid the deadlock tongue plate, and further, the deadlock tongue plate can be prevented more reliably.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention. Equivalent changes and modifications of the invention are intended to fall within the scope of the present invention.
