Abstract

The utility model relates to a lock for a refrigerator, which has the advantages of simple structure and little space occupation and can simultaneously lock an upper door and a lower door of the refrigerator. The lock for a refrigerator comprises a lock head, a lock seat and a lock rod, and is characterized in that the lock head is fixed on the lock seat, and the tail end of a lock core arranged on the lock head is provided with a shifting tooth; a guide hole is formed on the lock seat, and the lock rod extends into the guide hole; the lock rod has a strip-shaped hole in the position which corresponds to the shifting tooth of the lock core, and one side of the strip-shaped hole is provided with a tooth matched with the shifting tooth. When the lock core is rotated, the shifting tooth arranged on the lock core shifts the tooth on one side of the strip-shaped hole on the lock rod to drive the lock rod to move axially along the guide hole of the lock seat.

Description

The refrigerator lockset

Technical field

The utility model relates to a kind of lockset, particularly a kind of refrigerator lockset.

Background technology

At disclosed Chinese patent bulletin on January 24 calendar year 2001: disclosing application number among the CN2416196 is: 00214413 patent application, a kind of refrigerator door lock is disclosed in this application, by lock tube, lock core, lock core cover and dead bolt are formed, wherein lock core and lock core cover are positioned at lock tube cylindricality cavity, dead bolt is positioned at the lock tube end and is connected with the lock core cover, put at lock core and to be provided with strip lock core trepanning, the lock tube inwall of lock core trepanning lower end correspondence is provided with the translot of quadrant length, at lock tube inwall translot two ends axial vertical slot is set upwards, two vertical slots and translot connect and form a U-lag; The lower end of lock core connects a spring; Lock pin one end is fixed on the lock core, and the other end passes the lock core trepanning and is positioned at U-lag; During use it is installed on the door of refrigerator body, apply external force to lock core, spring is compressed, and lock core moves down together with the upright groove of lock pin along lock core trepanning and lock tube inwall, behind the arrival translot, rotary locking cylinder, lock core rotates along translot together with lock pin and lock core cover, overlaps fixing dead bolt with lock core simultaneously and rotates thereupon, revolves to turn 90 degrees another upright groove of back arrival, remove external force then, lock core resets at another upright groove of the effect lower edge of spring; Thereby make dead bolt relatively rotate 90 degree, realize locking of door body or the conversion of opening.The shortcoming of this lockset is that dead bolt rotates with lock core, so dead bolt takes up room big when rotating and can only lock a door, existing refrigerator mostly has two doors, can only be in the time of two doors being locked simultaneously respectively with two locksets, thereby its scope of application is little.

Summary of the invention

In order to solve the problem that the dead bolt that exists in the current refrigerator door lock takes up room greatly, can not lock two doors simultaneously, the utility model provide a kind of compact conformation, can be simultaneously with the refrigerator lockset of the door locked up and down of refrigerator.

Technical scheme:

A kind of refrigerator lockset comprises tapered end, lock and locking bar, it is characterized in that tapered end is fixed on the lock, and the lock core end on the tapered end is provided with moving tooth; Have pilot hole on the lock, locking bar stretches in the pilot hole, the position of corresponding lock core moving tooth has bar hole on the locking bar, one side of this bar hole is provided with the tooth that matches with moving tooth, when rotational lock core, the tooth that the moving tooth on the lock core is stirred bar hole one side on the locking bar makes locking bar move axially along the pilot hole of lock.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, the motion of dead bolt when the locking refrigerator doors is axially-movable, and it is little to take up room; And its displacement can be very big, will go up the Xiamen and lock simultaneously so dead bolt can pass the refrigerator median septum, only needs a lockset to get final product to two-door refrigerator, need not to act on two locksets.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the internal structure schematic diagram of refrigerator described in the utility model with an embodiment of lockset.

Fig. 2 is the left view that refrigerator is used lockset among Fig. 1 embodiment.

Fig. 3 is the view of taking away among Fig. 2 behind the locking bar.

Fig. 4 be Fig. 3 along A-A to cutaway view.

Among the figure 1, the Xiamen, 2, tapered end, 3, pintle hook lock, 4, lock, 401, pilot hole, 5, locking bar, 501, bar hole, 502, tooth, 6, moving tooth, 7, median septum, 8, to the doorstep.

The specific embodiment:

Fig. 1 is the internal structure schematic diagram of refrigerator described in the utility model with an embodiment of lockset, comprise tapered end 2, lock 4 and locking bar 5 in conjunction with Fig. 2, Fig. 3 and the visible described refrigerator of Fig. 4 with lockset, tapered end 2 passes on the shop front of Xiamen 1 and offers a porose interior rear flank of stretching into, pass the hole on the lock 4 again, pintle hook lock 3 snaps in the groove of tapered end 2 inboards tapered end 2 is fixed on lock 4 and the Xiamen 1, and the lock core end of tapered end 2 is provided with cross (Fig. 2 and shown in Figure 3) moving tooth 6; Have pilot hole 401 on the lock 4, locking bar 5 stretches in the pilot hole 401, has bar hole 501 on the locking bar 5, and a side of bar hole 501 is provided with the tooth 502 that matches with moving tooth 6.When locking, during rotational lock core, the tooth 502 that the moving tooth 6 on the lock core is stirred on the locking bar 5 makes locking bar move up along the pilot hole of lock, and median septum 7 is stretched into and to the doorstep in 8 the hole in locking bar 5 tops, because of median septum 7 is fixed, so at this moment the last Xiamen of refrigerator all can not be opened; When the backward rotation lock core, moving tooth 6 drives locking bars 5 and moves downward, and makes locking bar 5 tops and 8 separates with median septum 7 and to get final product to the doorstep.

Claims

1, a kind of refrigerator lockset comprises tapered end, lock and locking bar, it is characterized in that tapered end is fixed on the lock, and the lock core end on the tapered end is provided with moving tooth; Have pilot hole on the lock, locking bar stretches in the pilot hole, and the position of corresponding lock core moving tooth has bar hole on the locking bar, and a side of this bar hole is provided with the tooth that matches with moving tooth.
