Description

Lock for trunks or bags

The utility model relates to a kind of lock, and specifically a kind of bag lock belongs to field of lockset.

Existing bag lock is generally blade construction, and every lock has only a blade, and key is general, promptly can open many locks with a key.Even without key, as long as use and other roughly consistent instrument of key width, thickness, also lock can be opened, for this reason, a hook has been established at the middle part of existing case and bag again, so that with hanging lock that it is sealed, has influenced the attractive in appearance of case and bag.In order to change the deficiency of vane type lock, what have makes coded lock into, if password is few, confidentiality is little, just lock can be opened by feel, if password is many, confidentiality has had raising, but complex structure, cost up.

It is a kind of simple in structure that the purpose of this utility model is to provide, the pellet shot from a slingshot bag lock that security performance is good.

Solution of the present utility model is, this bag lock, and it has panel 12, overlap 6 fixing lock cores 5 by this panel and lock core, what be positioned at lock core 5 one sides opens hand 11, opposite side press hand 14, with the pressing board 8 that is connected as a single entity by hand 14, be positioned at the locking bolt 9 of pressing board 8 belows, with open arm-tie 7 that hand 11 fixedlys connected and spring 15, lock hook 10, base plate 16, clamping plate 17, its special character is that lock core 5 is a lock cylinder, the pellet shot from a slingshot of lock cylinder≤5, and to go up pellet shot from a slingshot 4 be hollow pellet shot from a slingshot.

The pellet shot from a slingshot of the described lock cylinder of the technical program is preferably 3.Like this, both guaranteed the confidentiality of bag lock, the volume of lock is more suitable in being installed on the case and bag.

Because lock core of the present utility model is lock cylinder, and the last pellet shot from a slingshot of lock core is hollow pellet shot from a slingshot, makes it compared with prior art, has simple in structurely, and volume is little, the advantage that security performance is good.

Accompanying drawing and drawing explanation:

Fig. 1-front view of the present utility model;

The A-A sectional view of Fig. 2-Fig. 1;

The B-B sectional view of Fig. 3-Fig. 1;

Wherein: 1-key, 2-pellet shot from a slingshot spring, the last pellet shot from a slingshot of 3-, pellet shot from a slingshot under the 4-, 5-lock core, 6-lock core cover, the 7-arm-tie, the 8-pressing board, the 9-locking bolt, the 10-lock hook, 11-opens hand, the 12-panel, 13-awl end trip bolt, 14-presses hand, 15-extension spring, 16-base plate, 17-clamping plate, 18-cap liner.

The utility model is described in further detail below in conjunction with accompanying drawing.With reference to figure 1-Fig. 3.The utility model mainly is made of lock body and lock hook two large divisions, and they can be separately fixed on the upper and lower case mouth of chest.Lock body overlaps 6 lock cores of fixedlying connected 5 by panel 12 by this panel and lock core.The pellet shot from a slingshot of lock core 5 is three, and upward pellet shot from a slingshot is hollow, so that pellet shot from a slingshot spring 5 can partly enter in the pellet shot from a slingshot when lock is in opening, makes the volume-diminished of lock.At the hand of opening of lock core 5 one sides, the groove that is arranged in panel 12 also can slide at this groove.One end of arm-tie 7 is inserted in out in the hole of hand 11 bottoms, and there is a square opening in its stage casing, and the dead bolt of lock core 5 is arranged in this hole.An end of pressing hand 14 with pressing board 8 rivetings be in the same place, the other end is connected on the panel 12 by rotating shaft, pressing board 8 cooperates with the ramp of locking bolt 9 by the outer inclined-plane of its underpart.One end of extension spring 15 is fixedly connected on the arm-tie 7, and the other end is fixed on the locking bolt 9, and the clamping plate 17 that are positioned at arm-tie 7, locking bolt 9 belows are fixedlyed connected with panel 12 with back cover 16.Lock hook 10 is independent workpiece.A kind of like this lock has just been made.Operating principle is.During unlatching, key 1 is inserted in the lock core 5, roller seating space coincide with following pellet shot from a slingshot on the key, upper and lower pellet shot from a slingshot separates at the lock core outer round surface, rotatable 90 ° of lock core, and at this moment dead bolt is to the restriction cancellation of arm-tie, stir out hand with hand, open the hand-motion arm-tie and move to left, under the extension spring effect, locking bolt and then moves to left, press bullet on hand and the pressing board, lock hook is deviate from, and lock hook separates with lock body, if it is installed on the chest, then the case mouth separates up and down.When sealed, lock hook is inserted in the lock bolt plate, press hand, pressing board moves to right locking bolt, and locking bolt pins lock hook, at this moment, the key return and extract, pellet shot from a slingshot moves down under the effect of pellet shot from a slingshot spring up and down, and lock core can't rotate, and then dead bolt can't move arm-tie, thereby locking bolt also can't move to left, lock hook can not be deviate from, if locking fixes on the chest, then chest is sealed.

Claims (2)
