Abstract

The utility model relates to a lock article for precaution, which is composed of function parts, such as a lock body, a lock bolt, a reset spring, a digital lock core for controlling unlocking, a lock hook, etc., wherein the reset spring is arranged between the lock bolt and the lock body, but the lock bolt and the lock body are in a translation slide fit. The digital lock core for controlling unlocking is in a structure that cylinders at the two ends of the digital lock core for controlling unlocking are in a movable fit with the lock body, and the middle part of the digital lock core for controlling unlocking is inserted and matched with a flute on the lock bolt via a protruding block. The utility model has the advantages of simple structure, few parts, small and exquisite appearance, good safety and reliability, low manufacturing cost and convenient and flexible installation and use, and is especially fit for the installation and use on notebooks, various cases, bags and other similar objects.

Description

Coded lock

A kind of locking product that the utility model relates to take precautions against.

Present widely used lockset is with key operated goods, need carry a lot of keys, and is very inconvenient, also loses easily sometimes, causes trouble.The code type of existing various different purposes lock on the market, on function, digital lock core, latch hook and its corresponding location that they are mainly opened by lock body, dead bolt, back-moving spring, control, fixed component etc. partly constitute, back-moving spring is installed between dead bolt and lock body, and dead bolt can move relative to lock body; What have also is provided with other structure division.The deficiencies in the prior art part mainly is: the digital lock core that their complex structure, especially control are opened and the structure of corresponding lock body are all comparatively complicated, and corresponding location, fixed component need be arranged, and cause the cost height.In addition, be subjected to the restriction of its structure, because member is many, whole lockset can not be made very for a short time, they be difficult to adapt to notebook, various casing or other similar products strick precaution, install and use.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of simply constructed coded lock product is provided.

Can take following technical scheme to realize purpose.This coded lock, still funtion parts such as digital lock core of being opened by lock body, dead bolt, back-moving spring, control and latch hook constitute, back-moving spring is installed between dead bolt and lock body, but dead bolt is translation gliding with lock body and cooperates, the digital lock core that control is opened be with two ends cylinder and lock body be movingly, the middle part is with the structure of inserting mutually of the groove on projection and the dead bolt.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of this coded lock;

Fig. 2 is a kind of structural representation of this coded lock;

Fig. 3 is a kind of structure and the assembling schematic diagram of the digital lock core of control unlatching.

This coded lock, because dead bolt 1 is translation gliding with lock body 2 and cooperates, promptly dead bolt is guide with the lock body, can parallelly moves relative to lock body again.The digital lock core 3 that control is opened is the structures so that two ends cylinder and lock body are movingly, the middle part is constituted with the groove inserting mutually on projection and the dead bolt, the projection that promptly has only groove on dead bolt and lock core middle part is to timing, projection can insert in the groove, dead bolt can move relative to lock body is parallel, realizes opening; When the projection at groove on the dead bolt and lock core middle part was thrown off, lock core can rotate arbitrarily relative to lock body, as long as have the projection of a lock core and the groove of dead bolt not to align, then dead bolt can not move relative to lock body, realizes locking.So it can be opened safely and reliably, lock, can reduce other unnecessary location, member such as fixing again, thereby the structure of coded lock is simplified significantly.Under the prerequisite that satisfies said structure, matching relationship, functions such as digital lock core of opening as for lock body 2, dead bolt 1, back-moving spring 4, control 3 and latch hook 5 are the specific constructive form of part all, installation site, the quantity of back-moving spring between dead bolt and lock body, the number of lock core, integrally-built size of lockset and pattern etc. all can be taken the circumstances into consideration to set according to using needs.Can make flexibly dissimilar, the series of products of different sizes.

Among the coded lock embodiment shown in the accompanying drawing 1, manually controlling the relative lock body mobile device of dead bolt, is the pull type structure that is made of the elongated hole 7 that move for handle the handle 6 and the lock body corresponding position that are fixed on the dead bolt.Its structure is the simplest.

Among the coded lock embodiment shown in the accompanying drawing 2, manually controlling the relative lock body mobile device of dead bolt, is that rotating handle, handle end are equipped with gear 8 on the lock body by being installed in, the rotational structure that has the teeth groove 9 that matches with gear to be constituted on the dead bolt.

Among the embodiment of coded lock shown in above-mentioned, according to different mode of occupation, both can be the horizontal translation formula structure that is slidingly matched between dead bolt and lock body, also can be the upper and lower translation formula structure that is slidingly matched.Their result of use does not have difference.

The digital lock core 3 that control is opened shown in the accompanying drawing 3, it is the digital adjustable structure that constitutes by stem stem 10 and the assembling of digital axle 11 two parts, when needing, by after the relative installation that changes digital axle and stem stem, again both are tightened to one, just can adjust the unlatching number of conversion lockset, improve the security reliability of lockset.Lock core also can be made into digital nonadjustable stationary structure.The structure result of use of accompanying drawing institute example is good.

The relative prior art of the technical program has following advantage and effect:

Simple in structure, parts are few, and are small and exquisite; Security reliability is good; Cheap for manufacturing cost, peace Fill flexible and convenient to use; Be particularly suitable for installing on notebook, various case, bag and other similar articles and make With.
