Abstract

The present invention relates to a refrigerator lock for locking a refrigerator door. The aim of the invention is to provide a refrigerator lock with a simple structure and being mounted conveniently,a lock pole foot section is provided with a guide rail hole having an included angle with a telescoping direction of the lock pole, a lock core foot section is provided with a pin rotating along an i nserted key and capable of being inserted into the guide rail hole and translating along a guide rail, and a pin is limited in the guide rail hole by a connecting piece. Due to the guide rail hole locating on the foot section of the lock pole, the pin rotating coaxially along a keyhole and locating on the lock core foot section, and the translation of the pin after being inserted into the guide rail hole, when the lock core rotates along with the key, the pin rotates and drives the lock pole to extend outwards or shrink inwards to implement a function of locking or unlocking. Due to the connecting piece for limiting the pin in the guide rail hole, the lock pole and the lock core are connected with each other without separation, when mounting, there only is one mounting component, structurebecomes simple, and installation is more convenient.

Description

A kind of refrigerator lock

Technical field

The present invention relates to be used to pin the refrigerator lock of refrigerator doors.

Background technology

Refrigerator lock is installed among the alveolar layer of refrigerator door usually, and the installation of lock need be carried out before foaming.Existing refrigerator lock is made up of lock core, lock, lock support and pintle hook lock four parts, in the process of installing, needs above-mentioned four installed parts are in place one by one, then again lock box is covered the lock installation place and also seals to avoid the bubble material to get into lock box.This type of lock construction installed part is more, has the shortcoming of complex structure, inconvenient installation.

Summary of the invention

The present invention is intended to provide a kind of refrigerator lock simple in structure, easy for installation.

The present invention provides a kind of refrigerator lock; Comprise lock core, lock, be stuck in the pintle hook lock on the lock core and cover on the outer lock box of lock core, lock and pintle hook lock; The lock core head is provided with and supplies key to insert the keyhole that rotates, and it is characterized in that, the lock afterbody has a guide rail hole that becomes angle with the flexible direction of lock; The lock core afterbody have one follow the key turns of being inserted and can insert guide rail hole after along the latch of wherein guide rail translation, have connector to be limited in latch in the guide rail hole.

The present invention is because the lock afterbody has a guide rail hole that becomes angle with the flexible direction of lock; The lock core afterbody has a latch of following the keyhole coaxial rotation; Latch can be along its guide rail translation after inserting guide rail hole; When so lock core is followed key turns, latch rotate thereupon and drive simultaneously lock overhanging or in contract and realize the function lock and unblank.Because there is connector to be limited in latch in the guide rail hole, lock and lock core are linked together can not break away from, be equivalent to lack an installing component during installation, structure becomes simply, installs more convenient.

The specific embodiment

Like Fig. 1,2; Lock 9 afterbodys have a guide rail hole 5 that becomes angle with lock 9 flexible directions; Lock core 6 afterbodys have a latch 4 of following the key coaxial rotation of the keyhole 10 that inserts lock core 6 heads; Latch 4 inserts in the guide rail hole 5, is riveted on latch 4 in the guide rail hole 5 by the riveting parts as connector 3.During assembling, be linked to be the lock 9, lock core 6 of one because the small and exquisite lockhole 12 that can as shown in Figure 2ly pass on the door face board 13 of structure is installed shaft locking sleeve 11, pintle hook lock 8, door end cap 14 and lock box 7 then.As shown in Figure 3 after the installation, this moment, latch 4 was positioned at the low order end in figure middle guide hole 5, and lock 9 front ends stretch out and are exposed at outside the lockhole 12, are locking state; From rotating counterclockwise 90 degree to key like the state of Fig. 3, then latch 4 rotates the high order end that arrives in the guide rail hole 5 thereupon, and is as shown in Figure 4, and lock 9 contracts after slightly but still is exposed at outside the lockhole 12 at this moment; Continue to rotate counterclockwise 90 degree then, latch 4 rotates the low order end that arrives in the guide rail holes 5, makes lock 9 withdraw fully in the lockhole 12, is unlocking condition.

Be provided with fastener 1 in the lock box 7,, be used for clamping lock axle sleeve 11, guarantee that lock box 7 installation sites are accurate like Fig. 4, shown in 5.

Be provided with limited block 2 in the lock box 7 and match, prevent lock core 6, lock 9 and pintle hook lock 8 offsets with lock core 6, lock 9 and pintle hook lock 8 shapes.
