Description

A kind of coded lock

The utility model relates to a kind of coded lock, belongs to a kind of of lockset.

Coded lock in the market mainly contains two kinds of electronic lock and mechanical code locks, the password of mechanical code lock all presets in advance, can not change, and need key operated, if key loss, can bring inconvenience to people, in addition, the door lock in hole with lock utilizes professional unlocking tool just can open, safety is not strong, for this reason, I work out a kind of do not need key operated, the coded lock that password can be reset by the user.

The purpose of this utility model provides a kind of coded lock, and having password can change at any time, and no keyhole does not need key operatedly, has safer, more reliable performance.

The utility model is achieved through the following technical solutions: a kind of coded lock, to form by fixed mount, plate washer, lock box base plate and lock core, and plate washer, the fixed mount that has a two through hole are connected with screw with the lock box base plate, constitute lock box, and lock core is installed in the lock box.The structure of lock core is: following frid is fixed on the lock box base plate with screw, has cavity independent of each other on the following frid, and puts movable block, spring and cryptographic block in the cavity; Have through hole independently of one another and that movable block can pass on the movable plate, the through hole that movable plate passes on the fixed mount is seated in down above the frid; Have chamber independent of each other on the location-plate, and be connected the location with fixed mount, plate washer with screw, put the T-shape drive link of pocketed springs in each chamber of location-plate, the top of drive link has bypass cavity, the link stopper of mounting strap spring in the bypass cavity; Have the through hole that the body of rod independently of one another, the T-shape drive link can pass through on the return plate, the through hole that the return plate passes fixed mount is placed in above the location-plate, the last plate washer that has through hole independently of one another is connected the location with fixed mount, plate washer with screw, have through hole independent of each other on the upper cover plate, put " doing " font button of pocketed springs in the through hole of upper cover plate, upper cover plate is connected with screw with plate washer with fixed mount; Through hole, the cavity number identical (number can be determined according to the needs of setting code) that have on following frid, movable plate, location-plate, return plate, last plate washer and the upper cover plate, the position corresponds to each other; The spring lever of two groups of springs of suit is welded on the fixed mount, the barrier casing that has through hole on return plate, the movable plate is contained on the spring lever, and one group of spring is positioned at the plate washer outside of return plate, another group spring is positioned at the plate washer outside of movable plate, spring lever is the welding gear pin between the plate washer of the plate washer of return plate and movable plate, the latch of band spring case is welded on the movable plate, and the lath of band pin is welded on the plate washer.

The utility model has the advantages that 1. switch door lock need not key, can avoid the inconvenience that brings to the user because of key loss.2. because of no keyhole,, satisfy people's safety requirements so utilize unlocking tool not open.3. password can be set at any time and change according to user's needs.4. because the structure of each button is identical, independently of one another, key number can increase when cast component or reduce as required at any time, satisfies the not needs of isotopic number password setting.
