Description

A kind of push type cam lock

Technical field

The utility model relates to cam lock fields, and in particular to a kind of push type cam lock.

Background technique

Cam lock or cam lock are a kind of locksets that lock rotation pinning is controlled by internal structure, according to its pinning knot The difference of structure is divided into: plum blossom spring lock, blade cam lock, triangle cam lock, double sides pellet cam lock etc..Such as Chinese patent text Offer the patent No. 201220432333.8 of middle disclosure, authorized announcement date on 03 27th, 2013, utility model title " chamber door cam lock ": a kind of chamber door cam lock, including cam lock body, cam lock core and lock tongue, cam lock core, which is fixed on, turns tongue It locks in intracorporal through-hole, lock tongue is fixed on one end of cam lock core.The chamber door cam lock also includes the first elastic component washer, first Hexagon thin nut plain washer, the second elastic component washer, the first hex nut.First elastic component washer, the first hexagon thin nut are used It is connected firmly on box door plate in by cam lock body, plain washer, the second elastic component washer, the second hex nut are used for S type Lock tongue is connected firmly on cam lock core.When cam lock core rotated ninety degrees, lock tongue is lockked or is opened.But above-mentioned cam lock knot Structure design is relatively simple, lock core component point due to being excessively exposed in lock body through-hole, be easy to be corroded and by people's malice outward Object is put into gap between the lock core and lock body of dew and causes lock core stuck, is not available key unlock, is caused cam lock Failure.

Utility model content

The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art,

A kind of push type cam lock is provided.

To achieve the above object, the utility model provides following technical solution: a kind of push type cam lock, including outside Matched key, spring bolt parts, lock core, lock body component, lock core one end connection spring bolt parts other end are connect with lock body component, lock tongue Component include locking nut, lock tongue and limited block, the lock tongue be equipped with lock tongue through-hole, the locking nut pass through lock tongue through-hole with Lock core is connected, and lock tongue through-hole one end is equipped with the limited block of limitation lock tongue rotational angle, and the lock body component includes installation Nut, seal washer, lock body, lock core are equipped with solution lock end compatible with key, it is characterised in that: the lock body is opened equipped with both ends The lock core accommodation groove of mouth, the solution lock end are arranged in lock core accommodation groove, one end and solution lock end end are equipped in the lock core accommodation groove Face is in conplane lock core protective shell, and the solution lock end consistent with solution lock end shape is offered in the middle part of the lock core protective shell Receiving hole.

By adopting the above technical scheme, lock body is the column construction that lock core accommodation groove is equipped with inside both ends open, is held in lock core It is open at one end in conplane lock core protective shell with lock body to set in slot setting, the solution lock end of lock core is arranged in lock core accommodation groove And be in same plane in lock core protective shell, offered on lock core protective shell and solve the consistent solution lock end receiving hole of lock end shape, Lock core is protected by the way that lock core protective shell is arranged, prevents lock core rapid wear or since there are different between lock body and lock core The phenomenon that object causes cam lock stuck.

A kind of above-mentioned push type cam lock can be further arranged to: be held between the lock core and lock core protective shell in lock core Set the pressing being equipped in slot when the pressing lock core protective shell exposure of external matched key solves lock end and external matched key is unlocked Tripper.

By adopting the above technical scheme, due to being provided with the solution lock end of lock core (i.e. at external key insertion rotation) in same The lock core protective shell of one plane, therefore traditional unlocking manner cannot play the role of unlocking, therefore pass through setting pressing solution Locking device, so that solution lock end can be exposed after key presses lock core protective shell to realize rotation unlock.

A kind of above-mentioned push type cam lock can be further arranged to: the being unlocked by pressing device includes to be set to lock core Elastic component between protective shell and lock core is equipped with elastic component in the lock core accommodation groove and limits shell, and described elastic component one end abuts It is abutted in the lock core protective shell other end with elastic component limit shell phase, is equipped with limit between the elastic component limit shell and lock core protective shell Position mechanism.

By adopting the above technical scheme, by the way that elastic component is arranged between lock core protective shell and lock core, elastic component is set around lock Outside core and it is located in lock core protective shell, shell is limited by setting elastic component, is limited between shell and lock core protective shell in elastic component Position-limit mechanism is set to promote the integrated level of entire being unlocked by pressing device, being unlocked by pressing device is integrated in one, improves dress With efficiency.

A kind of above-mentioned push type cam lock can be further arranged to: the position-limit mechanism includes that lock core protective shell is opposite The opposite spacing block set set up of solution lock end receiving hole other end inner wall is set, and the elastic component limit shell outer wall is equipped with and elastic component The integrally formed stop collar of shell is limited, the stop collar is equipped with the spacing breach being used cooperatively with spacing block set.

By adopting the above technical scheme, it is arranged by the other end inner wall for being oppositely arranged solution lock end receiving hole in lock core protective shell The opposite spacing block set set up limits the integrally formed stop collar of shell with elastic component in elastic component limit shell outer wall setting, is limiting The opposite spacing breach set up is opened up on the ring of position, the shape of spacing breach and the shape of spacing block set are consistent, thus by elastic Part limit shell is limited in lock core protective shell one end.

A kind of above-mentioned push type cam lock can be further arranged to: the elastic component is spring.

By adopting the above technical scheme, it not only save the cost and is easily assembled by setting spring for elastic component.

The utility model has the following beneficial effects: being equipped with lock core protective shell, reduces lock core wear intensity and improve the lock core service life and set The being unlocked by pressing device set further improves unlock convenience.

The utility model is described in further detail with reference to the accompanying drawings and examples.
