Description

The quadruple linkage electronic password lock

Technical field

The utility model relates to the coded lock field, specifically, relates to a kind of quadruple linkage electronic password lock, take machinery and electronic technology as the basis, has four buttons, can realize the locking of password setting, latch hook and unlatching.

Background technology

Electronic password lock has the advantages such as security performance height, cost be low, low in energy consumption makes its role as antitheft bodyguard more and more important.On making, based on the develop rapidly of electronic technology, cryptologic design that the easier realization of electronic password lock is comparatively complicated is so people have produced much the electronic password lock take the digital keys of " 0 "-" 9 " as cipher input.Yet such lock is because number of keys is many, and each button must guarantee the convenience of input action and feasible, so that lock body can not be made is too small and exquisite, this obviously is inapplicable for the limited occasion in application space.

The utility model content

Technical problem to be solved in the utility model provides a kind of quadruple linkage electronic password lock, makes cipher input simple.

The technical solution of the utility model is as follows:

A kind of quadruple linkage electronic password lock comprises lock body and locking mechanism, is provided with controlling organization and battery in the described lock body; Described surface of lock body is provided with Password Input mechanism; Described Password Input structure comprises numerical key, acknowledgement key, cancels key and finishes key.

Further: described lock body upside is provided with two openings.

Further: described locking mechanism comprises U-shaped latch hook, latch hook clamping pin and Compress Spring.

Further: the first end of described U-shape lock hook and the second end are inserted into respectively in the described opening; Described latch hook clamping pin and described Compress Spring are arranged in the described lock body; Described Compress Spring is enclosed within outside the first end of described U-shape lock hook; The second end inboard of described U-shape lock hook is provided with bayonet socket; Described latch hook clamping pin one end be connected controlling organization and connect, the described latch hook clamping pin other end contacts with described bayonet socket.

Further: described controlling organization comprises control circuit and chip, and described control circuit and described chip are electrically connected.

Further: described battery and described controlling organization and described Password Input mechanism are electrically connected.

Technique effect of the present utility model is as follows:

1, volume of the present utility model is little, is convenient for carrying.

2, the utility model can according to common man-machine interface, design suitable button diameter, handled easily.

The specific embodiment

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

As Figure 1-3, be respectively front view of the present utility model, lateral view and internal construction schematic diagram.

Quadruple linkage electronic password lock of the present utility model comprises lock body 101 and locking mechanism.Be provided with controlling organization 201 and battery 202 in the lock body 101.Lock body 101 surfaces are provided with Password Input mechanism.Password Input mechanism comprises numerical key 102, cancels key 103, acknowledgement key 104 and finish key 105.Numerical key 102 is used for the input one-bit digital.The numeral of the number of times of pressing for needing for example inputs 2, then by twice; Input 7 by seven times.Cancel key 103 and be used for when finding certain Password Input mistake, cancel a certain position password of having inputted, re-enter.Acknowledgement key 104 is used for confirming and should finishing for Password Input after a certain position Password Input finishes.For example, password is 9879, then press numerical key 102 9 times after, by an acknowledgement key 104; After pressing again 8 numerical keys 102, by an acknowledgement key 104; After pressing again 7 numerical keys 102, by an acknowledgement key 104; After pressing at last 9 numerical keys 102, by an acknowledgement key 104.Finishing key 105 is used for confirming this input password after all Password Inputs are finished.If password is correct, opened lock then; If the password mistake, then lock can not be opened.

Controlling organization comprises control circuit and chip, and control circuit and described chip are electrically connected.Chip is used for the program of storage coded lock, definition and realize numerical key 102, cancel key 103, acknowledgement key 104 and finish the function of key 105.Battery 202 and controlling organization 201 and Password Input mechanism are electrically connected, and are used to controlling organization 201 and Password Input mechanism that power supply is provided.

Lock body 101 upsides are provided with two openings.Locking mechanism comprises U-shaped latch hook, latch hook clamping pin 203 and Compress Spring 204.Latch hook clamping pin 203 and Compress Spring 204 are arranged in the lock body 101.The first end 205 of U-shape lock hook and the second end 206 are inserted into respectively in the opening; Compress Spring 204 is enclosed within outside the first end 205 of U-shape lock hook; The second end 206 inboards of U-shape lock hook are provided with bayonet socket 207; One end of latch hook clamping pin 203 is connected connection with controlling organization, the other end of latch hook clamping pin 203 contacts with bayonet socket 207.When this quadruple linkage electronic password lock was in the lock state, the other end of latch hook clamping pin 203 snapped in the bayonet socket 207.When this quadruple linkage electronic password lock was in unlocking condition, the other end of latch hook clamping pin 203 was retracted, and ejected from bayonet socket 207, and the U-shaped latch hook lockset position of coupler that upwards takeoffs under the elastic force effect of Compress Spring 204 is namely opened this quadruple linkage electronic password lock.

When using the utility model, by Password Input Mechanism input password.Controlling organization 201 judges whether the input password is correct.When input password when correct, the other end of controlling organization 201 control latch hook clamping pins 203 is retracted, and ejects from bayonet socket 207, and the U-shaped latch hook lockset position of coupler that upwards takeoffs under the elastic force effect of Compress Spring 204 is namely opened this quadruple linkage electronic password lock.When the Password Input mistake, the other end of controlling organization 201 control latch hook clamping pins 203 still is stuck in the bayonet socket 207, and this quadruple linkage electronic password lock can not be unlocked.

Although the utility model only has four button key,, the figure place that password is set can freely be determined, 3 passwords, 4 passwords, 5 passwords etc. can be set.The carry of numeral system also can be set to any number such as 8,10,16,24,36.In addition, 8 systems, 10 systems and 16 systems can be realized in the storage of the design of controlling organization and numerical value.This quadruple linkage electronic password lock volume is little, is convenient for carrying, and simultaneously, button can according to our normal man-machine interface, design suitable button diameter.Both make things convenient for operation, reduced again volume.

The above only is the specific embodiment of utility model.Protection domain of the present utility model is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
