Description

Primary and secondary key

Technical Field

The utility model relates to a key, concretely relates to primary and secondary key.

Background

The primary and secondary lock is a key lock with double unlocking cylinders, the key lock can be unlocked by the same primary key and different secondary keys, wherein the primary key only has one rack shape, the secondary keys can have various different rack shapes, the secondary keys are kept and used by an individual user, and the primary keys are kept and used by a primary and secondary lock system manager or a supervisor.

The master key and the slave key are processed from blanks of the same specification, each blank comprises a holding part for a user to hold and a matching part matched with a lock cylinder, each lock cylinder comprises a slave slot matched with the slave key and a master slot matched with the master key, each matching part comprises a base, the two sides of the base in the width direction are respectively provided with a slave unlocking tooth and a master unlocking tooth, the two sides of the base are respectively matched with the slave slot and the master slot, and when the slave unlocking teeth are processed and removed, the blanks form the master key; when the female unlocking tooth is machined away, the blank forms the child key.

However, the blank of the above structure has a certain disadvantage that since the sub unlocking tooth and the mother unlocking tooth are respectively located at both sides of the base in the width direction, a part of the base is inevitably removed when the sub unlocking tooth or the mother unlocking tooth is removed, which causes the strength of the base to be reduced, and further affects the service life of the sub key or the mother key.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, the utility model aims to provide a primary and secondary key that intensity is high.

In order to achieve the above purpose, the utility model provides a following technical scheme: including the main part, the main part includes the matching part that the part of gripping that supplies the user to grip and match with the lock core, matching part include the base, its characterized in that: the basal portion is located the same side protrusion of thickness direction and is provided with the son portion of inserting with son slot and the mother portion of inserting of mother slot, the side of son portion of inserting protrusion direction be provided with son and unlock the tooth or mother insert the side of portion protrusion direction and be provided with mother and unlock the tooth.

By adopting the technical scheme, the sub-insertion part and the main insertion part are arranged on the side surface of the base part in the thickness direction, the sub-unlocking tooth and the main unlocking tooth are respectively arranged on the sub-insertion part and the main insertion part, when a blank is required to be processed into a main key, the sub-unlocking tooth is ground from the sub-insertion part, the sub-unlocking tooth in the thickness direction is cut off singly, the base part is not influenced, the strength of the main key is not influenced, similarly, when the sub-key is processed, the strength of the sub-key is not influenced by grinding the main unlocking tooth from the main insertion part, the sub-unlocking tooth and the main unlocking tooth in the prior art are arranged on the side surface of the base part in the width direction, when the blank is required to be processed into the sub-key, the whole side surface of the base part in the width direction is used as the main unlocking tooth, the whole main unlocking tooth in the width direction of the base part needs to be cut off, and part of the base part is cut off, make the intensity of sub-key descend by a wide margin, relative this scheme only amputate mother on the female portion of inserting and unlock the tooth, the partial basal portion is amputated to current technique, and the area of its excision is far greater than this scheme, so the influence on the intensity also is far greater than this scheme, and remains female portion of inserting for the sub portion of inserting provides the guide effect under some conditions.

The utility model discloses further set up to: a groove is formed between the sub-insertion part and the female insertion part, and the sub-unlocking teeth are positioned on the side surface in the groove.

Through adopting above-mentioned technical scheme, regard sub-unlocking tooth as the internal tooth to set up at the recess internal tooth, and prior art's primary and secondary key can only adopt the external tooth structure, the contact surface of the inserted sheet of the lock core the inside that corresponds, all be on the same side on lock core jack length direction, the security and the theftproof nature of giving the key have all brought the hidden danger, easily be cracked, and this scheme sets up sub-unlocking tooth and sets up its rate of opening far below the external tooth of internal tooth, antitorque distortion and folding endurance can improve greatly, and sub-key is as offering the user to use, the sub-unlocking tooth shape diverse of its sub-key, and the sub-unlocking tooth as the internal tooth can provide more shapes of relative external tooth, each other rate greatly reduced.

The utility model discloses further set up to: a groove is formed between the sub insertion part and the female insertion part, and the female unlocking tooth is positioned on the lateral surface outside the groove.

Through adopting above-mentioned technical scheme, master key preparation volume is relative sub-key preparation volume, and master key can be less than sub-key, so set up mother's unblock tooth outside the recess, when the preparation sub-key, need grind and wash mother's unblock tooth to the plane, and mother's unblock tooth is as the external tooth, the secondary operation of being convenient for.

The utility model discloses further set up to: the sub-insertion part and the female insertion part form an unlocking group, and the unlocking group is arranged on two sides of the base part in the thickness direction.

Through adopting above-mentioned technical scheme, the basal portion all is provided with the group of unlocking in the both sides of thickness direction for the key can be in positive direction and negative direction use, and convenient to use person's unblock need not pay close attention to the positive and negative of key when the unblock.
