SUMMERY OF THE UTILITY MODEL

To sum up, for overcoming the not enough of prior art, the utility model provides a case and bag trick lock that the function is stable, simple structure.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a simple structure's case and bag trick lock, includes casing, password wheelset, jam plate, locking piece and locking closure, the casing with the jam plate be equipped with respectively with password wheelset complex first race and second race, password wheelset with the casing is connected, the locking piece is equipped with the jack catch, the casing both sides link respectively has the locking piece, the locking piece is equipped with the first piece that resets, the locking closure with the casing is connected, the locking closure corresponds the jack catch position is equipped with the jack catch groove, the jam plate is equipped with the second piece that resets, password wheelset controls when rotatory the jam plate swings its characterized in that: the outer end of the lock plate is provided with a lock head, the lock head and the lock plate are integrally arranged, and the lock head has a first position for blocking the lock block to slide and a second position for not blocking the lock block to slide when swinging.

The arrangement is that when the password wheel set is rotated to the correct password, the locking plate is pressed down by the resetting device, the lock head is positioned at the second position where the sliding of the sliding block is not blocked, the two locking blocks are not blocked in the sliding paths and can freely slide, at the moment, the closed clamping jaws on the case can be inserted into the clamping jaw grooves to push the two clamping jaws, the two locking blocks are pushed back to the original positions by the first resetting piece after completely entering the first position, the pushing back paths of the closed clamping jaws are closed, the closed clamping jaws cannot be directly taken out, the sequence of the password wheel set is disordered, the locking plate is bounced when the password wheel set is disordered, the lock head swings to the first position where the locking blocks are blocked, the blocking pieces are added in the sliding paths of the two locking blocks and cannot slide, the clamping jaws cannot be opened, the password wheel set is rotated to the correct password again when the password wheel set needs to be opened, the locking plate is pressed down by the resetting device again, simple structure, the connection that needs the linkage is few, and is more stable.

Furthermore, a stop block is arranged on one side, back to the clamping jaw, of the locking block, the distance between the stop block and the shell is larger than the thickness of the lock head, the lock head is located between the two stop blocks, and the swing height of the lock head is not higher than the stop blocks.

So set up, when password wheelset turned to correct password, the jam plate was pushed down by resetting means, and the tapered end was located the dog below, can't block the slip of locking piece, and when password wheelset's order was disturbed, the jam plate was bounced by password wheelset, and the tapered end is located in the middle of two dogs, and the tapered end can withstand earlier the tapered end when the locking piece slided, can't continue to advance simple structure, need not extra part.

Furthermore, a boss is arranged on one side, back to the shell, of the stop block, and a movable groove is formed in the position, corresponding to the boss and the lock head, of the lock cover.

Due to the arrangement, the swingable angle of the lock head is increased, the contact area of the stop block and the lock head is increased, the forced opening possibility is reduced, and the required precision requirement during processing is reduced.

Further, still include the wheel cap, the wheel cap with the casing is connected, be equipped with the draw-in groove between two figures on the password wheelset, the wheel cap correspond the position of password wheelset be equipped with draw-in groove complex elastic plate.

So set up, avoided the password wheelset to pop out when rotating to the elastic plate can insert the draw-in groove and block the password wheelset when rotating corresponding digit, but the correct angle of rotation inaccuracy of password can not appear, leads to the condition of not opening, and the elastic plate also can be bounced hard a little, can not influence normal rotation.

Further, the second resets for the spring, the second resets and is located the wheel lid with between the jam plate, the second resets to the wheel lid exerts the effort towards the casing.

So set up, the second piece that resets just can be compressed when password wheel leaves the correct position, and the restoring force of the second piece that resets just can push down the jam plate when password wheel changes the correct position, simple structure.

Furthermore, first piece that resets is the spring, first piece that resets is located between two locking pieces, first piece that resets exerts the effort of another locking piece dorsad to two locking pieces respectively.

So set up, the jack catch receives gas when the locking piece slides under artificial operation, and the first piece that resets is compressed, and the restoring force of the first piece that resets just can exert reverse effort to the locking piece during pine hand, makes the locking piece get back to original position, simple structure.
