Abstract

The utility model relates to a door lock which is used on the sliding door, comprising a lock shell [1]. The middle of the interior of the lock shell [1] is provided with a crank [2] which is arranged in the indoors direction, or a gear wheel [3] which is arranged on the rotation of the lock core in the outdoors direction. When the gear wheel [3] is rotated, two racks [4, 5] are driven to move top and bottom. The two racks [4, 5] are respectively connected with the pin holes [10, 11] of the two hook shape lock bolts [8, 9] through the cylinder pins [6, 7] which are arranged on the two racks. When the two racks [4, 5] move top and bottom, the two hook shape lock bolts [8, 9] are toggled to rotate around the bolt shaft [12, 13] which are fixed on the lock shell [1]. When the lock is opened, the two hook shape lock bolts [8, 9] respectively rotate into the interior of the lock shell [1]. When the lock is closed, the two hook shape lock bolts [8, 9] respectively rotate out of the interior of the lock shell [1] and rotate into and hook a padlock which is arranged on the door frame, and then the sliding door is locked. The utility model has small volume and convenient lock opening and closing. Two hook shape lock bolts are locked from the reverse directions, which guarantees the sufficient safety.

Description

The Parallel moving door lock

Technical field

The utility model belongs to a kind of door lock, the door lock of particularly a kind of use on Parallel moving door.

Background technology

The structure of the Parallel moving door lock of using always is that a center runner drives upward lower door frame pit of upper and lower strut insertion, and its deficiency is that volume is big, and the moment that the switching lock needs is also bigger, and particularly when Parallel moving door was higher, problem was more outstanding.

The utility model content

The purpose of this utility model is: provide a kind of volume little, open and close the light Parallel moving door lock of lock.

The technical solution of the utility model is: a kind of Parallel moving door lock, comprise a rectangle lock housing of holding each parts in the lock, at described lock housing bosom, be provided with one by the rocking handle that is installed in indoor direction or be installed in the gear that the lock core of outdoor direction rotates, described gear drives inner two toothed rack with its engagement of described lock housing and moves up and down when rotating, described two toothed rack are by the straight pin on it, be connected to respectively and be installed in the up and down pin-and-hole on two hook-type dead bolts of both sides of described lock housing inside, stirring described two hook-type dead bolts when described two toothed rack move up and down rotates around the dead bolt axle that is fixed on the described lock housing, when being in unlocking condition, described two hook-type dead bolts all change described lock housing inside over to, when being in blocking, described two hook-type dead bolts all produce from described lock housing inside, change and hook the lock hanging that is installed on the doorframe over to, Parallel moving door is pinned.

The utility model volume is less, and the switching lock is light, and two hook-type dead bolts lock from opposite both direction, can guarantee enough degrees of safety.
