Description

Novel double open is locked

Technical field

The utility model belongs to concealed lock technical field, and in particular to a kind of novel double open lock.

Background technology

In lockset development technique field, for the reason such as antitheft, in door used in safety cabinet or secrecy building interior Lock is mostly Lock opened with two keys, and the unlocking mode of such a structure must be locked on the door using two keys to be switched, still, the prior art On the double key door lock unlocking form researched and developed it is more universal, for many years after use, it is fast that such door lock can be unlocked personnel Speed cracks opening, its feature has the drawbacks of very big, for drawback existing in the prior art, as industry technical staff, It is highly desirable to design the double opening lock of a new structure, passes through different unlocking modes, or the cooperation of two different keys Mode realizes the switch of door lock to solve the technical drawback of existing double opening lock.

The content of the invention

In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of novel double open lock, with The technical drawback of existing double opening lock is solved,

Technical solution is used by the utility model solves its technical problem：

A kind of novel double open lock, it includes primary key and secondary key, it further includes a tapered end, and the front end of tapered end is consolidated Surely there is lock sheet, tapered end internal whorl is fixed with a lock tube, and one is fixed between the rear end of the lock tube and tapered end and is determined Bit slice, is fixed with a lock core inside the lock tube；On the lock core, its top surface is equipped with former and later two protrusion positioning, The rear of protrusion positioning is multiple spring leafs, on the lock core, is positioned to be equipped with a side at an angle of 90 degrees degree position with protrusion Face positions, and the side positions the right side for being arranged on lock core；On the lock tube, on its top surface, two are equipped with front position It is a to position corresponding two location holes with raised；On the lock tube, two grooves, the groove are provided with its internal diameter Setting position and location hole set into an angle of 90 degrees degree.

Pitch-row between two location holes is identical with two raised positioning spacing.

Two grooves on the lock tube internal diameter are disposed adjacent, and there is interval between two grooves.

The primary key is longer than secondary key, and the front end of primary key is provided with a protrusion of unlocking.

The utility model has the advantages that：The utility model designs more than, by the use of primary key, After two raised positioning are depressed, rotate lock core and turn over two location holes, then turning by secondary key, it will lock Side positioning pressure on core, avoids two grooves of lock tube internal diameter, is acted by two above, the utility model realizes lock Switch；The utility model has used new unlocking mode, has distinguished the mode that existing double key is unlocked completely, has played very well Anti-theft effect, be it is a kind of preferably novel double open lock.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the dimensional structure diagram of the utility model；

Fig. 2 is the disassemblying structure schematic diagram of the utility model；

Fig. 3 is dimensional structure diagram on the inside of the lock tube of the utility model；

In figure, 1, secondary key, 2, primary key, 3, tapered end, 4, lock sheet, 5, lock tube, 6, lock core, 7, locating plate, 21, Unlock raised, 51, location hole, 52, groove, 61, spring leaf, 62, raised positioning, 63, side positioning.

Embodiment

The utility model is described further below by way of embodiment, a kind of novel double open lock, it includes primary Key 2 and secondary key 1, it further includes a tapered end 3, and tapered end 3 is fixedly arranged at the front end with lock sheet 4, and 3 internal whorl of tapered end is fixed There is a lock tube 5, a locating plate 51 is fixed between the rear end of the lock tube 5 and tapered end 3, the inside of lock tube 5 is solid Surely there is a lock core 6；On the lock core 6, its top surface is equipped with former and later two protrusion positioning 62, and the rear of protrusion positioning 62 is Multiple spring leafs 61, the setting of spring leaf herein is identical with existing lock core internal structure, on the lock core 6, is positioned with protrusion 62 position 63 into a side is equipped with an angle of 90 degrees degree position, and side positioning 63 is arranged on the right sides of lock core 6；Described On lock tube 5, two and 62 corresponding two location holes 51 of raised positioning are equipped with its top surface, at front position；The lock On set 5, two grooves 52 are provided with its internal diameter, the setting position of the groove 52 and location hole 51 are set into an angle of 90 degrees degree Put, also, the pitch-row between two location holes 51 is identical with two 62 spacing of raised positioning, and two grooves 52 are adjacent to be set Put, there is interval between two grooves 52.

The utility model designs more than, in use, it is by the use of primary key 2, because primary key is longer, its Front end is provided with unlocking protrusion 21, protrusion 21 of unlocking will after insertion, by two it is raised position 62 pressures, its push principle with it is existing Lock core spring pushing principle is identical, and details are not described herein again；After lock core 6 acts more than, it rotates and turns over two location holes 51, then turning by secondary key 1, by under the side positioning pressure 63 on lock core 6, avoid two grooves on 5 internal diameter of lock tube 52；In acting above, it is necessary to two keys are inserted into lock core according to order, otherwise lock core 6 can not be rotated, pass through two above Action, what the utility model realized lock matches somebody with somebody combination switch；The utility model has used new unlocking mode, has distinguished completely existing The mode that double key is unlocked, plays good anti-theft effect, is a kind of preferably novel double open lock.
