Description

Coded lock

Technical field

The utility model relates to the coded lock technical field, particularly a kind of coded lock that is applicable to notebook or writing case.

Background technology

In order to protect individual notebook not opened by other people in case stopping leak leaks privacy contents such as individual diary easily, many notebooks that have lock have appearred on the market.Common this notebook just combines mechanical lock and notebook are simple, but such Mechanical Builds is not attractive in appearance, uses yet inconvenience.In patent 200520089803.5, the lock on the notebook is improved, but still have complex structure, use inadequately problem easily.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of push-button puzzle lock simple in structure, easy to use is provided.

To achieve these goals, the technical solution adopted in the utility model is: coded lock, include the upper cover plate and the lower cover of mutual fastening, and fasten in the formed cavity at upper cover plate and lower cover, also be provided with slide bar, button and spring; Be arranged with the corresponding key hole of several and keytop shape size on upper cover plate and the lower cover; Slide bar is in a side of lower cover, and the dead bolt of its bottom passes the opening of lower cover, hangs on the hook; Slide bar one end is connected on the lower cover by spring, and the baffle plate of the other end and lower cover upper process offsets; Be equipped with block or following block with each corresponding position of cover plate key hole on the slide bar; The slide bar top is provided with a projection, passes the opening of upper cover plate, forms the zip key; Between the key hole of lower cover, be equipped with dividing plate, have locating piece on the dividing plate; Button passes from the key hole on overhead gage and the lower baffle, has location retaining, allocation tongue and retaining groove on the button, wherein the last block on location retaining and the slide bar and following block at grade, the locating piece butt on allocation tongue and the dividing plate.

As to improvement of the technical scheme, the shape of allocation tongue and locating piece is triangle or arc.

As to improvement of the technical scheme, the zip key is located at the middle part or an end of coded lock.

Identical as improvement of the technical scheme being pushed away the locking key surface configuration with the keytop shape

After adopting said structure, this upper cover plate and lower cover fasten the push-button puzzle lock and the notebook itself that form and form an overall structure, and its profile and style can be arranged in pairs or groups as required; Unlocking cipher just configures during fabrication, only need press the button of appointment during use, can unload lock hook easily, and notebook is opened.If do not know password, then coded lock is firmly locked, safe and reliable by the snap action of the block up and down on button block and the slide bar.The design that retaining groove on the button, allocation tongue match with locating piece on the dividing plate makes that the coded lock structure is simpler.Push away the design of locking key, simplified the structure of product, reduced the possibility that breaks down.

Below in conjunction with accompanying drawing the utility model is described further.

Figure of description

Fig. 1 is the utility model lower cover structure chart;

Fig. 2 is the utility model Slide bar structure figure;

Fig. 3 is the utility model press-key structure figure;

Fig. 4 is the structure chart that the utility model lower cover combines with button.

The specific embodiment

Referring to Fig. 1, lower cover 1 comprises key hole 11, dividing plate 12, dead bolt opening 13 and slide bar block 14.Wherein key hole 11 has eight, and shape and key shape are complementary; Dividing plate 12 is located between the key hole 11, also is provided with locating piece on it; Dead bolt opening 13 slides therein for the dead bolt of slide bar.

Referring to Fig. 2, slide bar 2 comprise push away locking key 21, go up block 22, block 23, dead bolt 24 and spring jacking block 25 down.It is one-body molded with slide bar 2 wherein to push away locking key 21, and the top passes from upper cover plate, during use by about push away locking key 21 slide bar 2 that slides, the unlatching coded lock.Dead bolt 24 passes from the dead bolt opening 13 of lower cover 1, hangs on the hook.Spring jacking block 25 links to each other with lower cover by spring, and behind the slip slide bar, because the elastic reaction of spring, slide bar can be got back to initial position again like this.

Referring to Fig. 3, button 3 comprises that locating retaining 31, allocation tongue 32 and retaining groove 33. wherein locatees retaining 31 and last block 22 and following block 23 in one plane, when pushing the wrong password, at least having a location retaining 31 and the last block 22 that is adjacent or following block 23 offsets, the obstruction slide bar slides, and coded lock can't be opened.Locating piece butt on allocation tongue 32 and the dividing plate 12, its position just is fixed on the top of locating piece at ordinary times, and button 3 passes from the upper cover plate surface; When pushing button after 3, the position of allocation tongue 32 moves to the locating piece below, and button 3 passes from lower cover 1 surface.Retaining groove 33 is parallel with dividing plate 12, and the design of retaining groove 33 is to have elasticity when making allocation tongue 32 by locating piece, moves convenient.

After will assembling with upper-part, in advance, set password by being set on the slide bar on the everywhere block or the position of block down.The numeral that a correspondence is all arranged on each button, as password is set is 168, and then at the button place of numeral 1,6 and 8, last block or time block on button location retaining and the slide bar that is adjacent offset, at all the other button places, the location keeps off with adjacent last block or following block and not offseting.When opening coded lock,, moved the position of location retaining on these three buttons if only press 1,6 and 8 three numerical key, make itself and adjacent last block or down block no longer offset, then when promoting slide bar zip key, the motion of slide bar can not hindered, and is opened coded lock smoothly.If pushed the wrong password, then have the location retaining of a button and the last block that is adjacent at least or descend block to offset, hinder the slide bar motion, coded lock just can't be opened.
