Abstract

The utility model discloses a support structure of a driving member of a lock unit, which is arranged in a tubular element of a lock body. The tubular element is connected with a handle, and one lock unit is contained in a central hole of the handle; the lock unit is provided with a rotatable lock core which is connected with a driving member; the driving member is provided with a first surface and a second surface which are separately arranged; a transverse sliding element which is provided with a projection part and a bearing part is arranged at the transverse position of the tubular element and is eccentrically pressed by an elastic element; the projection part of the transverse sliding element moves between the position on which a location hole is meshed with the handle and the position on which the location hole is not meshed with the handle; and the support structure is provided with a support part. When the first surface of the driving member moves close to the support part of the support structure, and the second surface of the driving member moves close to the bearing part of the transverse sliding element simultaneously, the transverse sliding element can restrict the displacement of the transverse sliding element under the action of external forces.

Description

The support structure of the driving member of lock group

Technical field

The utility model relates to the technical field of lock, is meant especially in a kind of tube element that is installed on lock, supports the support structure of the driving member of lock group.

Background technology

In the lock body of generally commonly using, the leader roughly is installed on the tube element of lock body, its connected mode is the support that is subjected to a flexible member with a removable mounting in the horizontal slip element of tube element, and be engaged in the locating hole of handle, handle has a through hole again, and described through hole can a ccontaining lock group, and this lock group connects a driving member, and driving member can limit moving of this horizontal slip element when locking, does not then limit moving of this horizontal slip element when unblanking; When so dismantling handle, all must make the driving member of lock group be positioned at unlocking condition earlier, press the horizontal slip element of pressing on the tube element with hand-held tool (or thin plate), the horizontal slip element of tube element is separated with the locating hole generation of handle, can reach the purpose of dismounting handle, when right this shortcoming is blocking, though the driving member of lock group can prop up horizontal slip element, but because there is the existence of clearance the junction of core and driving member, and driving member has the phenomenon of rocking, so this moment is if act on horizontal slip element place with hand-held tool (or thin plate) pressure by the horizontal slip element of tube element or with improper external force, because driving member can rock can't be really against horizontal slip element, so horizontal slip element pressurized is by displacement, can cause horizontal slip element to break away from the locating hole of handle, handle be produced with tube element separate; As No. the 5077994th, United States Patent (USP), the handling device that is disclosed and the combination of tube element, also be the above-mentioned shortcoming of improvement.

The utility model content

Main purpose of the present utility model provides a kind of support structure of locking the driving member of group, and the driving member that can make the lock group reaches the driving member that supports this lock group when blocking, and can limit the displacement of this horizontal slip element, makes lockset safer.

For reaching above-mentioned purpose, the utility model is adopted following technical solution:

A kind of support structure of locking the driving member of group is installed in the tube element of a lock body, and this tube element connects the leader, and this handle has a locating hole and a centre bore, a ccontaining lock group in this centre bore; This lock group has a rotatable core, and this core connects a driving member, and this driving member has one first and one second that is spaced apart; One horizontal slip element is installed on the horizontal position of this tube element, is subjected to the bias voltage of a flexible member; This horizontal slip element has a protuberance and a support, and the protuberance of this horizontal slip element is in mobile between the position of the locating hole of this handle of engagement and the position of locating hole of not meshing this handle; This support structure has a support portion, abut the support portion of this support structure when first face of this driving member, second face of this driving member abuts the support of this horizontal slip element simultaneously, and this moment, this horizontal slip element was subjected to the external force effect, and limited moving of this horizontal slip element.

This support structure is a ring, and these ring central authorities have the centre bore that wears for this driving member.

This ring can be accepted the bias voltage of a spring, and the side of this ring is abutted in the side of this horizontal slip element.

This ring has an outer ring surface, and this tube element has an inner tubal wall, and when ring is installed in the tube element, the outer ring surface of this ring abuts the inner tubal wall in this tube element.

Adopt such scheme, when the utility model is positioned at unlocking condition when the driving member of lock group, this moment, second face of driving member did not abut in the support of this horizontal slip element and first face does not abut in the support portion of ring, be inserted in the locating hole of handle with hand-held tool (or thin plate), promote the protuberance of horizontal slip element, make horizontal slip element be positioned at the position of the locating hole that does not mesh this handle, so get final product the removal handle so that change the lock group; When the driving member of lock group is positioned at blocking, this moment, second face of driving member abutted in the support of horizontal slip element, and first face abuts in the support portion of ring, if be inserted in the locating hole of handle with hand-held tool (or thin plate), because laterally the support of slip element and second face of driving member contact with each other, the support portion of ring and driving member first is adjacent to each other, so support of first support portion that can be encircled of the driving member of lock group, driving member can not produced laterally to be moved, can prevent that so handle from being dismantled by the thieves or robbers who act under cover of night and unblank, make lockset safer.
