Abstract
The utility model provides a five-coupled anti-theft lock. A driving gear is additionally arranged on the lock core of a common mechanical door lock on the basis of the common mechanical door lock. The driving gear is connected with a transmission gear and is coaxially connected with a functional gear by intermediate gears; meanwhile, a pair of linkage racks is arranged on the functional gear. Two ends of each of the linkage racks are respectively connected with one linkage rod. When the lock core is screwed, after the driving gear is driven to rotate, the transmission gear and the functional gear are driven by the intermediate gears to rotate, and the linkage rods are driven by the linkage racks to complete the locking to each linkage point at the time of the rotation. The five-coupled anti-theft lock integrates five locks, only one key is used for pointing on one position, and five linkage points can be simultaneously locked.
Description
The utility model relates to mechanical door lock, particularly a kind of 5-linked theftproof lock.
The door lock made of technology routinely, its internal construction no matter, perhaps how outward appearance changes, and always can not change the characteristics at place's locking.So when meeting the robber by sled, often the robber is easy to do pries open this place just and can open door.In view of this, people have to load onto many locks simultaneously and be used for antitheftly on door, though can reach certain antitheft purpose like this, increase many troubles to the user virtually, therefore are not best anti-theft measure equally.
The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of collection five to lock in one, with a key at place's crawl 5-linked theftproof lock of five interlock points of locking simultaneously just.
The utility model comprises: doorframe (1), lock body (2), last tongue pull bar (3), last tongue connecting rod (4), lock core (5), sublingua tooth bar (6), dead bolt formations such as (7) up and down, its technical solution is: a driving gear (8) is set on lock core (5), and this gear is to be connected with a joggle by mesomerism gear (9) and travelling gear (10), simultaneously with the coaxial function gear (11) that differs in size with it in addition that is connected of travelling gear, the both sides of function gear are provided with a linkage gear (12) respectively, (13), this distich carry-over bar respectively with the gangbar (14) of lock body (2) upper and lower side, (15) connect.
Gangbar of the present utility model is positioned at each one up and down of lock body, gangbar on it (14) extends the auxiliary dead bolt A place of doorframe (1) upper end, and gangbar (15) is the auxiliary dead bolt D place that extends doorframe (1) lower end down, be connected with C with auxiliary dead bolt B respectively by set bar (16) at the middle part of linkage from top to bottom bar simultaneously, all have auxilliary tongue skewed slot (17) on dead bolt B and the C, gangbar can be slided in skewed slot by set bar (16).
The utility model is to collect five and locks in one, just can five interlocks of while locking point at place's crawl with a key.Have characteristics reasonable in design, simple in structure, convenient and practical, safe and reliable, that theftproof performance is good.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a locking states schematic diagram of the present utility model;
Fig. 2 is an opening schematic diagram of the present utility model.
As shown in Figure 1: the 5-linked theftproof lock comprises doorframe (1), lock body (2), goes up tongue pull bar (3), goes up tongue connecting rod (4), lock core (5), sublingua tooth bar (6), dead bolt (7), driving gear (8), mesomerism gear (9), travelling gear (10), function gear (11), interlock tooth bar (12), (13) up and down, and gangbar (14) (15), set bar (16), auxilliary tongue skewed slot (17) is common constitutes.
Embodiment: on the basis of existing standard machinery door lock, driving gear (8) is arranged on the lock core (5), driving gear is again by mesomerism gear (9) travelling gear (10) that is connected with a joggle, with the coaxial function gear (11) that differs in size with it in addition that is connected of travelling gear, said interlock tooth bar (12) (13) is separately positioned on the both sides of function gear (11), and the interlock tooth bar connects a gangbar (14) (15) respectively by connecting pin (18).When turning key rotation lock core (5), drive driving gear (8) and rotate, drive travelling gear (10) again by mesomerism gear (9) and rotate, drive and the coaxial function gear of travelling gear (11) transmission simultaneously.The interlock tooth bar (12) (13) that is arranged on these gear both sides this moment also begins action, thereby drives gangbar (14) (15) action.When gangbar (14) (15) when moving up and down respectively, respectively locking auxiliary dead bolt A and D, be arranged on the auxiliary dead bolt B and the C at gangbar middle part simultaneously, also carry out locking by set bar and auxilliary tongue skewed slot (17), and finished whole implementation process by gangbar.
Claims (2)
1, a kind of 5-linked theftproof lock, by doorframe (1), lock body (2), last tongue pull bar (3), last tongue connecting rod (4), lock core (5), sublingua tooth bar (6), dead bolt formations such as (7) up and down, it is characterized in that: go up at lock core (5) driving gear (8) is installed, this gear is connected with a joggle by mesomerism gear (9) and travelling gear (10) again, simultaneously with the coaxial function gear (11) that differs in size with it in addition that is connected of travelling gear, the both sides of function gear are provided with an interlock tooth bar (12) respectively, (13), tooth bar (12), (13) connect gangbar (14) respectively, (15).
2,5-linked theftproof lock according to claim 1, it is characterized in that: described gangbar is positioned at each up and down of lock body (2), gangbar on it (14) extends the auxiliary dead bolt A place of doorframe (1) upper end, and gangbar (15) is the auxiliary dead bolt D place that extends doorframe (1) lower end down, be connected with C with auxiliary dead bolt B respectively by set bar (16) at the middle part of linkage from top to bottom bar simultaneously, all have auxilliary tongue skewed slot (17) on dead bolt B and the C, gangbar can be slided in skewed slot by set bar (16).
