Description

A kind of lock construction

【Technical field】

The present invention relates to a kind of lock construction, the displacement being applied between object and object limits.

【Background technology】

The effect of lockset is that object and object are carried out displacement restriction.In practical applications, people are often through lockset pair Object carries out displacement restriction, to carry out anti-theft protection to object.Therefore, the security performance of lockset become it is main face ask Topic.

【Utility model content】

The utility model is intended to disclose a kind of lock construction, which has excellent anti-theft performance, security performance high, be not easy by Illegal person unlocks.

The technical solution that the utility model is taken is：

A kind of lock construction, including the first lock body and the second lock body；

First lock body includes lock housing, forced section, the first lock core and tie down screw；Forced section, the first lock core and locking Screw rod is sequentially connected, and is integrally formed, and forced section and the first lock core are contained in the lock housing, and tie down screw stretches out lock housing；

First lock core correspondingly has the first key；

The forced section is solid male member, the torsion for bearing the first key；Stress end surface offers and first The lockhole that key matches, lockhole extend to the first lock core；

The lock housing outer surface is fixedly connected with positioning male member；

Second lock body include the locking nut to match with the tie down screw and with the positioning male member phase The positioning female members matched, locking nut are fixedly connected with positioning female members；

First lock body further includes being useful for lid to close locking closure in the lock housing, be provided on locking closure open for controlling or The second lock core of locking closure is closed, the second lock core correspondingly has the second key.

Further, the lockhole is that cylindrical or more piece is cylindrical.

Further, the forced section is the right prism that bottom surface is in polygon.

Further, the positioning male member is axially extending along tie down screw, and the positioning female members is provided in locking screw Hole on female matrix.

It is had the advantage that using technical solutions of the utility model：

1. the forced section and the first lock core in the utility model are contained in lock housing, lock housing inner space is small, needs special Key can just stir forced section and the first lock core, it is compact-sized, it is safe.In addition, lock housing is provided with locking closure, locking closure setting There is the second lock core.By the setting of two layers of lock core, the security performance of lockset is considerably increased.

2. a kind of lock construction of the utility model has the first lock body and the second lock body, pass through the first lock body and the second lock body Between locking or unlock realize locking between object and object or unlock, it is flexible and convenient to use.

Reference numeral therein：The first lock bodies of 10-, 11- lock housings, 12- locking closures, the second lock cores of 121-, 13- stress Portion, the first lock cores of 14-, 15- tie down screws, 16- lockholes, 17- positioning male members, the second lock bodies of 20-, 21- locking nuts, 22- positions female members, the first keys of 30-.

【Specific implementation mode】

The utility model is described in further detail below in conjunction with specific embodiment.It is worth mentioning that below Embodiment is that the utility model implements feasible preferred technique scheme, is not to limit the scope of protection of the utility model.

Referring to attached drawing 1 to 4, a kind of lock construction, including the first lock body 10 and the second lock body 20.First lock body 10 includes Lock housing 11, forced section 13, the first lock core 14 and tie down screw 15；Forced section 13, the first lock core 14 and tie down screw 15 connect successively It connects, is integrally formed, forced section 13 and the first lock core 14 are contained in the lock housing 11, and tie down screw 15 stretches out lock housing 11.

First lock core 14 correspondingly has the first key 30.

The forced section 13 is solid male member, the torsion for bearing the first key 30.Preferably, forced section 13 is bottom Face is the right prism of polygon.13 end face of forced section offers the lockhole 16 to match with the first key 30, lockhole 16 to first Lock core 14 extends.Lockhole 16 is that cylindrical or more piece is cylindrical.First key 30 stretches into lockhole 16, the first lock core 14 and lock housing 11 Between it is in the unlocked state, twist the first key 30, forced section 13 together with the first lock core 13, tie down screw 15 with respect to lock housing 11 revolve Turn；The first key 30 is extracted, locking state is between the first lock core 14 and lock housing 11.

11 outer surface of the lock housing is fixedly connected with positioning male member 17.

Second lock body 20 include the locking nut 21 to match with the tie down screw 15 and with the convex The positioning female members 22 that part 17 matches, locking nut 21 are fixedly connected with positioning female members 22.Preferably, 17 edge of positioning male member Tie down screw 15 is axially extending, and the positioning female members 22 is the hole on 21 matrix of locking nut.

Further, the first lock body 10 further includes being useful for lid to close the locking closure 12 in the lock housing 11, is set on locking closure 12 It is equipped with for controlling the second lock core 121 for opening or closing locking closure 12.Second lock core 121 correspondingly has the second key.It beats Unlocking lid 12 is forced section 13 and the first lock core 14 it can be seen that inside lock housing 11.

The application method of the lock：Locking closure 12 is opened using the second key, is inserted into the first key 30, the first lock core 14 and lock housing 11 is in the unlocked state, and the first key 30 coordinates with forced section 13, and forced section 13, tie down screw 15 are twisted by the first key 30 It is rotated relative to lock housing 11, the screw-in tie down screw 15 of locking nut 21 is simultaneously gradually close to 11 side of lock housing, when locking nut 21 pastes When nearly lock housing 11, the positioning male member 17 on 11 outer surface of lock housing matches to limit with the positioning female members 22 on the second lock body 20 Lock housing 11 moves in tangential direction relative to the second lock body 20, extracts the first key 30, and the first lock core 14 is in locking with lock housing 11 State, at this point, the first lock body 10 and the second lock body 20 are in the state that is locked.It can be incited somebody to action by reversely rotating the first key 30 Locking nut 21 is screwed out from tie down screw 15, and the first lock body 10 and the second lock body are in solution open state.

In use, the first lock body 10, the second lock body 20 are fixedly connected with two articles respectively, pass through the first lock body It 10 and second locking between lock body 20 or unlocks the locking between realizing two articles or unlocks.
