Description

External thin padlock

Technical Field

The invention relates to a padlock, in particular to an external thin padlock.

Background

The existing thin padlock with small thickness is generally unlocked by pushing a button from a side door, while the side-push unlocking requires a blocking force to be applied from the other side surface of the lock, and even if two hands are not used, the lock can be unlocked by matching a plurality of fingers of one hand. The pressing type can be unlocked only by pressing with a finger, but the thickness of the luggage padlock pressed by the top surface is larger, and the whole luggage is installed outside the luggage and is too convex to influence the use of the luggage. In order to reduce the part of the buckle lock outside the luggage, part of the cloth on the edge of the luggage needs to be cut off, so that the buckle lock part passes through the hole for cutting off the cloth to be installed, the buckle lock of the luggage is inconvenient to install, the integrity of the luggage is damaged, and the strength of the luggage is reduced.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 4, the external thin buckle lock of the present invention includes a lock catch 13 fixed on one opening and closing side of a box 18, a lock case 11 installed on the other opening and closing side of the box 18, a lock hook 63 capable of being inserted into the lock catch 13 to lock the box, a main lock 21 located in the lock case 11, a driving mechanism installed at a predetermined opening of the lock case 11, a transmission member 61 driven by the driving mechanism to pull the lock hook 63, and a lock block 31 located behind the transmission member 61 and capable of sliding laterally, wherein a lock cylinder 62 is disposed at a rear end of the transmission member 61, the lock block 31 is provided with a lock slot 32 aligned with the lock cylinder 62 to unlock and lock in a staggered manner, the main lock 21 is provided with a lock plate 22, a return spring 23 for returning the lock plate 22 to an unlocking position, and a linkage spring 33 having two ends respectively fixedly connected to the lock plate 22 and the lock block 31. When the main lock is unlocked, the locking plate 22 is moved to the unlocking position under the action of the return spring 23, and meanwhile, the locking block 31 is synchronously linked to move to the unlocking position, namely, the locking groove 32 is aligned with the locking column 62, at the moment, the locking block 31 does not block the driving part 61 from retreating, so that the driving part 61 can retreat and the drawing locking hook 63 withdraws from the lock catch 13, and the luggage unlocking is realized. The locking groove 32 of the locking piece 31 is used for carrying out dislocation locking and aligned unlocking with the locking column 62 of the transmission piece 61, and the linkage spring 33 is used for enabling the locking piece 22 to drive the locking piece 31 to carry out locking or unlocking. The linkage spring 33 here may be other linkage members, such as a linkage rod.

In order to make the lock have the functions of both a combination lock and a mechanical lock, the lock shell 11 is provided with a secondary lock 51 which can push the lock block 31 to align the lock slot 32 with the lock cylinder 62, the main lock 21 is set as the combination lock, the secondary lock 51 is set as the mechanical lock, and the secondary lock 51 can be a TSA lock. The secondary lock 51 comprises a rotatable lock core and an inclined pushing block 52 protruding from the side surface of the lock core, and during the rotation of the lock core, the inclined pushing block 52 pushes the locking block 31 to align the lock groove 32 with the lock cylinder 62, so that the transmission member 61 can be retracted to unlock. During the unlocking process of the secondary lock 51, the primary lock 21 is normally in a locked state, and the linkage spring 33 disposed between the locking piece 31 and the locking plate 22 of the primary lock 21 can be compressed, so that the inclined pushing piece 52 can push the locking piece 31 to overcome the elastic force of the linkage spring, and move to the alignment of the locking groove 32 and the locking column 62, so that the transmission member 61 can retreat for unlocking.

Specifically, lock shell 11 articulates there is convertible locking closure 12 that can cover in latch hook 63 top, latch hook 63 slidable mounting is in this locking closure 12, and the rear end of latch hook 63 and the front end of driving medium 61 are equipped with the mutual lock joint of formula separation and reunion hook, latch hook 63 and driving medium 61 looks alternate segregation when locking closure 12 is turned up, driving medium 61 and latch hook 63 lock joint transmission when locking closure 12 closes. The lock cover 12 with the lock hook 63 together functions as a linkage latch, that is, the lock cover 12 is fastened on the upper side of the lock hook 63, and the lock hook 63 is inserted into the latch 13 to be locked.

As shown in fig. 3 and 4, the driving mechanism is a button 15 having a guiding and pushing groove 16 disposed obliquely, the transmission member 61 has a driven convex column 66 extending into the guiding and pushing groove 16, and a return spring (not shown) is disposed at the bottom of the button 15 or at the bottom side of the transmission member. The guiding push slot 16 and the driven convex column 66 are matched for transmission, so that the direction of button pressing and restoring force can be changed into horizontal push-pull power, and the driving piece 61 is controlled to move forwards and backwards in a translation manner.

As shown in fig. 3 and 4, the main lock 21 is a combination lock, the combination wheels of the combination lock are arranged side by side in the transverse direction, the combination wheels are provided with positioning concave parts 26 which are concave inwards, and the locking plate 22 is provided with positioning convex parts 25 which are convex and matched with the positioning concave parts. When the password is correct, the positioning convex part 25 extends into the positioning concave part 26 to realize positioning, the locking plate 22 retreats under the action of the return spring 23, the linkage spring 33 drives the locking block 31 to retreat at the same time, the locking groove 32 and the locking column 62 are switched from a dislocation state to an alignment state, and the transmission piece 61 can retreat to unlock. On the contrary, when the password is incorrect, the locking piece 22 cannot retreat, and the locking groove 32 and the locking column 62 maintain a dislocated state, so that the locking hook 63 cannot retreat to maintain a locked state.

As shown in fig. 3 and 4, the main lock is provided with a code adjusting piece 28 and a code adjusting switch 35, the code adjusting piece 28 is provided with a shifting notch 29 and is stacked on the lower side of the code wheel with the lock plate 22, the code adjusting switch 35 is provided with a shifting arm 39 which is inserted into the shifting notch 29 in a matching manner and a shifting head 38 which extends out of a reserved opening of the lock case 11, the finger pushes the shifting head 38 to enable the shifting arm 39 to press the side wall of the shifting notch 29 to enable the code adjusting piece 28 to move to a code setting position, the code wheel can be rotated to set a code at the code setting position, the finger pushes the shifting head 38 to a code locking position, the lock can be unlocked only when the code is correct, and the main lock is locked when the code is incorrect.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
