Description

The peep-proof device of combination lock

Technical field

The utility model is a kind of peep-proof device of combination lock, is in details of the words about a kind of combination lock design with peep-proof device.

Background technology

Lockset is in order to antitheft common utensil in all trades and professions, its kind is quite various, such as with lock body, core, lock hook, the lockset that dead bolt is formed, mainly insert core in lock body end, and lock hook is positioned at the lock body other end, lock hook one end is flexibly connected with lock body, dead bolt contacts with core interlock again in lock body, the lock hook other end then stretches in lock body and fastens with dead bolt, therefore user can match the key of core and insert core rotating, promote or pull dead bolt and lock hook to depart from, then lock hook can eject by lock body part relatively, allow lock hook one end leave lock body and become released state, this is then general key lock, and along with the progress of lockset manufacturing technology, there is again relevant dealer release using numerical ciphers combination as the lockset of locking means.

But general existing combination type lockset primary structure is all at least by a box body, one lock hook, one movable rod and several dial formed, and reach structural efficacy by snap action relation to each other, for convenience of general existing combination lock explanation now, applicant special Yin Li China's No. M421970th, utility model patent " Double-mechanism lock core structure " illustrates for front case, and please refer to as shown in accompanying drawing Figure 11 to Figure 12, when button ditch 81 and the movable part 82 of this shaft member 80 fin 83 " not " mutually contraposition (namely engaging) time, if under the incorrect state of password figure of that is user institute switch combination disk 84, this fin 83 is headed on by circle portion, shaft member 80 periphery 85, and movable part 82 can be made to resist the elastic force of elastic component 86 and move down, so the top rib 87 of this movable part 82 can be against between two dead bolts 881 of locked instrument 88, thus make locked instrument 88 can not in retraction locked instrument groove 89, so this lock box 90 carries on the back body 91 still locking condition with lock.

If when stirring combination disk 84 and making the button ditch 81 of each shaft member 80 all with after corresponding fin 83 contraposition (namely engaging), that is the password of this all combination disk 84 switch is under correct status, movable part 82 can because up being passed by elastic component 86, top rib 87 is made then to leave between the dead bolt 881 of locked instrument 88, and the dead bolt 881 of locked instrument 88 can be allowed mobile in locked instrument groove 89 by pushing and pressing, thus make lock box 9 carry on the back body 91 with lock and opened and become the state of unblanking.

Moreover, this type of coded lock manufacturer is when producing, for making shaft member 80 can simple combination and corresponding convenience with whole combination disk 84, it can be provided with the second button ditch 811 at the other end of shaft member 80, so that can quick alignment when assembling shaft member 80 and combination disk 84, is also because of cause for this reason, therefore prier also can utilize the instrument of spying 92 to spy upon the second button ditch 811 of shaft member 80 sometimes, and reach the effect of pry, so also there is the necessity preventing from spying upon, and as shown in figure 15.

Utility model content

Technical problem underlying to be solved in the utility model is, the combination type lockset overcoming prior art existence can by the disappearance of spying upon, and a kind of peep-proof device of combination lock is provided, provide combination lock sealed effectiveness originally, reach every peep-proof structural efficacy of the present utility model.

The utility model solves the technical scheme that its technical problem adopts:

A kind of peep-proof device of combination lock, it lock back of the body body comprising lock box and can be pivoted or be fixed to lock box, and lock box is provided with corresponding several slotted eyes, and be separately provided with a lock can be fixedly arranged on lock the back of the body body, and this lock comprise an accommodation seat, one movable part, several combination disk, several shaft member, and locked instrument, wherein this accommodation seat offers a storage tank and a locked instrument groove, this movable part and combination disk are located in storage tank, this movable part bottom is provided with at least one elastic component, each and the movable part in these elastic component two ends and storage tank cell wall butted, movable part is supported by the holder of elastic component elasticity, and movable part is provided with several appearance hole, these several appearance holes are for embedding corresponding several combination disk in wherein, and one end of movable part forms a top rib, this shaft member one end wears combination disk, and with combination disk secure bond, thus make shaft member must be driven to relatively rotate when switch combination disk, and shaft member one end is formed with first, second circle portion, periphery, and its circle portion, the second periphery is positioned at the correspondence position of combination disk and lock box slotted eye, and the first button ditch is then provided with again in its circle portion, the first periphery, and utilize a pivot to wear in combination disk and shaft member, and pivot two ends are combined with accommodation seat and locate, on movable part, be separately provided with several fin in addition, and the position of this fin is for the first button ditch to the first circle portion, periphery, this locked instrument is for being located in the locked instrument groove of accommodation seat, and locked instrument is also at least provided with a locking body, this locking body must move axially in locked instrument groove, and the change in location of top rib by movable part, and make locking body be limitation in displacement or change, and then reach locking body locking lock box and lock back of the body body, whereby, when peep-proof person again utilize laminal spy instrument stretch into slotted eye time, its can only test in circle portion, shaft member first periphery without any difference, and then reach device effect of the present utility model.

The beneficial effects of the utility model are, provide combination lock sealed effectiveness originally, reach every peep-proof structural efficacy of the present utility model.
