Abstract
The utility model provides a card-type pin tumbler lock cylinder with surface cover positioning. The card-type pin tumbler lock cylinder with the surface cover positioning is characterized in that the lock cylinder, arranged at the lower portion of a pin tumbler, is provided with an interlayer, and a slot and a key slot are formed in the corresponding position of the interlayer and the lock cylinder. A second locking piece which is matched with a key is arranged at the lower end of the lock cylinder pin tumbler, and at least one end of the second locking piece is blocked in the slot of a lock cylinder body. In the locking state, the second locking piece is jacked by an elastic mechanism to be blocked in the slot. In the unlocking state, the second locking piece is jacked by the key to move to an inner space in the interlayer. The second locking piece is rotated under the drive of the key when the second locking piece is in the inner space of the interlayer. When the key is inserted, except the cooperation of the pin tumbler and the key is successful, the key is needed to cooperate with the second locking piece successfully, so that the lock cylinder can be rotated to open a lock. The card-type pin tumbler lock cylinder with the surface cover positioning has the advantage of being good in security performance.
Description
Technical field
The utility model relates to a kind of card form lock cylinder with the cover location.
Background technology
Existing lock cylinder, the fit structure that generally only has pellet and key, lock core exposes cover, can see the lock core of rotation fully, so long as pellet cooperates successfully with key, just can unblank, because pellet is to be connected in one with keyhole, lock core exposes, and thief can adopt technological means to crack the pellet position, lock is opened, and theftproof is poor.
The utility model content
The purpose of this utility model just provides a kind of namely have pellet and key fit structure, the fit structure that key length and cover end face are arranged again, at least the twice anti-theft feature can be set, lock core is blocked and can't unblank with technological means by cover, the card form lock cylinder of the cover location that theftproof is good.
Solution of the present utility model is such: the utility model comprises key and lock core, lock core is positioned in the lock core body, is provided with cover at lock core body, and described key is card form, the middle part of axis direction is circular, in the card upper end one section column shaped rotating section is arranged; The shape that the Kong Weiyu key shape that described cover is opened matches is inserted the state that puts in place at key, and the card upper end breaks away from the cover card slot.
Described key is the structure of single-side belt card, and described cover card slot is monolateral groove structure, and also can adopt key is the structure of double-side band card.
Described key is card form, and the one side has bullet groove, and opposite side has at least one card slot; Described lock core arranges card, described card has arc groove, and card plane of living in and key direction of insertion intersect, and matches with the position of key card film trap in the position of card arc groove, when key insertion lock core put rotation in place, the arc groove that the card slot of key is stuck in card rotated.
The utility model has the advantages that theftproof is good.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the structural representation of the utility model when cooperating with key.
Accompanying drawing 2 is structural representations of cover B003.
Accompanying drawing 3 is upward views of accompanying drawing 2.
Accompanying drawing 4 is structural representations of key B0011.
The specific embodiment
Each parts detail of accompanying drawing is as follows: B001 is lock core body, and B002 is card, and B003 is cover, and B004 is the lock core back-end block, and B005 is lower lock core, and B006 is upper lock core, and B007 is the second lock dog, and B008 is interlayer, groove B009, spring B 0010, key B0011.
As shown in Figure 1, the utility model comprises key B0011 and lock core, and lock core is positioned in the lock core body, be provided with cover B003 at lock core body B001, described key B0011 is card form, and the middle part of axis direction is circular, in the card upper end one section column shaped rotating section A is arranged; The shape that the Kong Weiyu key shape that described cover B003 opens matches is inserted the state that puts in place at key B0011, and the card upper end breaks away from the cover card slot.
Described key B0011 is the structure of double-side band card.
When using the utility model, the hole that the shape of key B0011 and cover B003 open cooperatively interacts, just can insert lock core, after insertion puts in place, must cooperate successfully with pellet, and the card slot of key B0011 card upper end disengaging cover B003, key B0011 column shaped rotating section A is in the hole of cover B003, just can rotational lock core.
Present embodiment also increases anti-theft measure one, and namely described key is card form, and the one side has bullet groove, and opposite side has at least one card slot; Described lock core arranges card B002, described card B002 has arc groove, card B002 plane of living in and key direction of insertion intersect, match with the position of key card film trap in the position of card B002 arc groove, when key insertion lock core put rotation in place, the arc groove that the card slot of key is stuck in card B002 rotated.
In the present embodiment, lock core is to be divided into up and down lock core, and this structure is that other patent is protected.
