Description

Small-core hook lock

The utility model belongs to a kind of small-sized lock that is applied on the furniture.

The aluminium head diameter that present drawer, chest door, commode door in office and family generally uses is about 16 millimeters little core bounce tongue lock, mainly constitute by copper core, aluminium head and dead bolt, its principle is, make dead bolt flexible by rotating the copper core along the direction vertical with copper core center line, skewer is gone in the groove of the housing that matches with drawer or wicket, and the rotation of the pulling of drawer or wicket all is to move along the direction identical with copper core center line, therefore can reach the effect of pinning drawer or wicket.But when wicket is along the direction vertical with the center line of copper core during with the mode switch that moves, the direction that the flexible direction and the wicket of dead bolt move is identical, and this situation does not just reach the effect of locking a door.

The purpose of this utility model is: design and a kind ofly can be suitable for above-mentioned drawer or rotary type wicket, can be applicable to the little core lock of portable wicket again.

The purpose of this utility model is achieved in that copper core, aluminium head, round end pellet shot from a slingshot, tack pellet shot from a slingshot and the spring that it has comprised that common lock had, the copper core can be done 90 ° of rotations, different is, the terminal squarely of copper core, the hook sheet that a strip is arranged, the one end has a square opening to be inserted in copper core end and is fixed on copper core end by connecting screw, and the other end of hook sheet has the recess of a hook-type; The aluminium back of head is not provided with the part retraction inwards symmetrically of tack pellet shot from a slingshot, spring, thereby forms the cross section of 2 symmetries, the screw that matches with set screw that 2 symmetries are arranged on the cross section; The rear portion of aluminium head is also being overlapped an endoporus and is being a bit larger tham the spacer of aluminium back of head profile, and 2 apertures that match with set screw are arranged on the spacer; The front end of aluminium head increases a circle a little.

The groundwork principle of said structure is such, because the copper core can rotate 90 °, just can drive the hook sheet and rotate 90 °, make the hook sheet go in the groove of the housing that matches with drawer or rotary type wicket with the rotating manner skewer, at this moment the dead bolt role of hook sheet and little core bounce tongue lock is finished identically, and only skewer is gone into the mode difference of groove.And when on portable wicket, using, lock body can be rotated 90 ° of installations toward hook sheet recess direction, at this moment the permanent position of hook sheet is in the horizontal direction.During use, rotational lock core so just can pin wicket by set pin in the housing that recess hooks with wicket matches of hook sheet.Design of the present utility model has as can be seen from the above analysis enlarged the range of application of little core bounce tongue lock.In addition, the design of spacer and aluminium head front end not only makes lock body be fixed on the plank, and, because spacer is movable, the distance between it and the aluminium head front end can be done adjustment among a small circle, therefore, make this lock can adapt to the plank of different-thickness within the specific limits, conveniently install and use.

With reference to the accompanying drawings the utility model is further described below.

Accompanying drawing 1 is the bullet tongue portion structural representation of existing little core bounce tongue lock.

Accompanying drawing 2 is assembling drawings of the present utility model.

Accompanying drawing 3 is hook plate shape schematic diagrames of the present utility model.

Accompanying drawing 4 is aluminium back of head cross-section cutaway views of the present utility model.

With reference to accompanying drawing 1, the operating principle that can see common bounce tongue lock is, skewer pin [3] is fixedly linked with copper core [5], rotating copper core [5] just can be by skewer pin [3], the plush copper that drive is drawn together on the head [6] is controlled the flexible of dead bolt [1], and latch bolt spring [4] plays fixedly dead bolt [1], and case [2] not only contains above-mentioned each parts, and the screw hole that is provided with on it, whole lock body can be fixed on the plank.

With reference to accompanying drawing 2,3, the cooperation of copper core of the present utility model as can be seen [8], aluminium head [15] and round end pellet shot from a slingshot [20], tack pellet shot from a slingshot [12], spring [11], aluminium pin [10] is finished identical with the cooperation of common lock.Key [7] rotates 90 °, promptly rotatable 90 ° in copper core [8].Different is, dead bolt [1] is replaced by hook sheet [14], and an end of its square opening is fixed in the end of copper core [8] by pad [17], spring washer [18] and connecting screw [19].Because the profile that the endoporus of spacer [13] is a bit larger tham aluminium head [15] rear portion, thereby can move easily to regulate and match by the part that set screw [16] and aluminium head [15] front end increase a circle whole lock body is fixed on the plank, copper sheathing shell [9] increases one with aluminium head [15] front end and encloses that partly to encase be effect attractive in appearance.

With reference to accompanying drawing 2,4, can see that aluminium head [15] rear portion is not provided with the part of tack pellet shot from a slingshot [12], spring [11], retraction and the shape of 2 symmetrical sections forming inwards symmetrically, and on the cross section, the position of the screw [21] that matches with set screw [16].

As can be seen, little core bounce tongue lock is with screw case [2] to be directly fixed on the plank and to reach the fixedly purpose of lock body, thereby the thickness of plank will be selected identical with the length of aluminium head from accompanying drawing 1.The aluminium head length degree of general this lock is 2 centimetres, therefore can only be suitable for the plank of 2 cm thicks, has so also just influenced the scope of application of lock.And from accompanying drawing 2 as can be seen, spacer [13] can move at the rear portion of aluminium head [15], when aluminium head [15] length was 3 centimetres, this lock just can be suitable for the plank of 2-3 cm thick.

Because this lock is mainly used in drawer, chest door, the commode door, so aluminium head [15] diameter is also selected 16 millimeter.
