Abstract

A refrigerator lock, which comprises a lock sleeve, a lock core, a top shaft, a lock sheet, a pressure spring, a key and a dialing plate, is characterized in that: two pairs of arc-shaped limit slots are provided on the inner wall of the lock sleeve; a lock core inside the lock sleeve is at least equipped with a through hole vertically crossing the axial line, so that the lock sheet can be plugged in; a dead hole, which is in parallel with and linked to the through hole, is also provided on the lock core; a resetting spring is placed inside the dead hole, and a polygonal concave hole for the key is provided on the end part of the lock core; a top shaft hole for the top shaft is provided in the center of the lock sheet; arc-shaped faces on both ends of the lock sheet match arc-shaped limit slots of the lock sleeve; besides, a clamping sheet on the lock sheet is also provided to fit the resetting spring inside the dead hole; the clamping sheet matches the top shaft, so that the resetting spring can be maintained inside the dead hole; the top shaft at least provides a clamp slot to match the top shaft hole on the lock sheet, for which the utility model has advantages of convenient fabrication, simple structure and being unlocked quickly and conveniently.

Description

Refrigerator lock

Technical field

The utility model belongs to a kind of lock, especially a kind of Refrigerator lock.

Background technology

There are complex structure in existing refrigerator lock, Ice cabinet lock, a kind of lock that can be used for refrigerator, refrigerator-freezer is disclosed at present, because lock core is made of preceding lock core and rear lock core, interconnect by projection and groove, processing time consuming is installed inconvenience, along with the increase of service time, occur the certain angle of key idle running easily, correspondingly prolonged the time of unblanking and closing.

Summary of the invention

The purpose of this utility model is: a kind of Refrigerator lock is provided, and it not only processes, easy to use, and volume is little, and open, close fast, convenient.

The purpose of this utility model is achieved in that a kind of Refrigerator lock, and it is made up of lock tube, lock core, apical axis, locking plate, stage clip, key, group plate, its special character is: two pairs of arc stopper slots are arranged on the inwall of lock tube, and the center line of the arc of two pairs of arc stopper slots intersects and is vertical mutually; The lock core that is positioned at lock tube has a through hole that vertically passes its axis for the locking plate insertion at least, also has parallel with through hole and a be communicated with blind hole on the lock core, is placed with back-moving spring in the blind hole, and there is a polygonal inward recess that supplies key to insert the end of lock core; There is an apical axis hole for the apical axis insertion in the central authorities of locking plate, the cambered surface at locking plate two ends cooperates with the arc stopper slot of lock tube, and locking plate and arc stopper slot matched in clearance, also have on the locking plate that the interior back-moving spring of blind hole cooperates on a card and the lock core, card cooperates with apical axis back-moving spring is remained in the blind hole; Has a draw-in groove that cooperates with locking plate upper top shaft hole on the apical axis at least, one end of apical axis passes the apical axis hole on the locking plate that is positioned at lock core, be positioned at the polygonal indent nose end of lock core, the other end of apical axis has a compression spring, and the other end of lock core is enclosed in spring, apical axis in the lock core endoporus with screw.

Two through holes that vertically pass its axis for the locking plate insertion are arranged on the lock core, two parallel with through hole and be communicated with blind holes, being installed in has two locking plates on the lock core.

The cross section of apical axis is a waist shape, and the cross section of draw-in groove is " right-angled trapezium ".

Apical axis is cylindrical, and described draw-in groove, draw-in groove are " right-angled trapezium " of a ring apical axis.

A kind of Refrigerator lock of the present utility model, lock core are one, and locking plate is installed a slice, so easy to process, simple in structure; Two pairs of arc stopper slots are arranged on lock tube, can 360 ° of rotations, because the effect of back-moving spring, the locking plate action is fast, the effect of compression spring resets apical axis fast, so unlatching is quick and convenient.
