Abstract
The utility model relates to a cam connecting rod type linking mechanism for a side lock-tongue and upper and lower lock-tongue. The utility model is used for an anti-theft door. Under the control of the direct operation of a middle lock (12), the linking mechanism realizes that the side lock-tongue (4) and the upper and the lower lock-tongue (2) extend out outwards and simultaneously for locking and retract inwards and simultaneously for opening, and a problem of high requirement of installation accuracy is overcome. The installation accuracy of the linking mechanism can be broadened, and the utility model has the advantages of flexible rotation, good safety performance and strong damage resistant capability.
Description
The utility model is a kind of cam link formula side dead bolt and dead bolt link gear up and down, is used for anti-forcing open the door.
At present template swing type side dead bolt and dead bolt link gear up and down, installation accuracy requires high, if error occurs when installing, will reflect the side dead bolt and up and down the dead bolt while protruding, withdraw, uneven in length, and different strength phenomenon.
The utility model has designed a kind of cam link formula side dead bolt and dead bolt link gear up and down at above-mentioned situation, this interlinked mechanism is under the control of middle lock (12) direct control, realize side dead bolt (4) and dead bolt (2) protruding locking simultaneously and withdraw inwards simultaneously and open up and down, this mechanism has overcome the demanding problem of installation accuracy.
Accompanying drawing is cam link formula side dead bolt and last following dead bolt link gear.
The utility model is to realize like this (such as figure): Cam-linkage type side lock Tongue and lock tongue linking mechanism up and down are by dead bolt gathering sill (1) up and down, dead bolt up and down (2), side dead bolt gathering sill (3), side dead bolt (4), upper and lower strut (5), Small rod (6), short lock shaft (7), cam (8), pillar (9), long lock shaft (10), Middle connecting rod (11), middle lock (12) form, and this interlinked mechanism is contained in prized up-proof door Big door leaf is symmetrical in middle lock (12) near opening the shoulder place, and side dead bolt (4) has A hole, pitch-row prized up-proof door, big door leaf upper and lower end face 400mm, cam (8) Be isosceles triangle, the place has three hinge holes at three angles, is respectively charged into pillar (9), small rod (6) and upper and lower strut (5), with short lock shaft (7), centre Connecting rod (11), long lock shaft (10) connect small rod (6) other end and side Dead bolt (4) connects, and the upper and lower strut other end is connected structure with dead bolt (2) up and down Become Cam-linkage type side dead bolt and lock tongue linking mechanism up and down.
The utility model security performance is good, and survivability is strong, and installation accuracy can be relaxed, and rotates flexibly, does not have other strength phenomenon.
Below in conjunction with accompanying drawing an embodiment is described: after each part processing is finished among the figure, dead bolt (2) up and down, small rod (6), upper and lower strut (5) connects into little assembly with rivet, cam (8) is integrally welded with short lock shaft (7), fixing pillar (9) again, each part connects the back and is connected with rivet with middle lock (12), driving two cams (8) by middle lock (12) contraction at last makes the dead bolt upper and lower sides do locking to unclamp action, long lock shaft (10), short lock shaft (7), pillar (9), process with engine lathe, upper and lower strut (5), small rod (6), cam (8), intermediate connecting rod (11) is used the plate shearing machine blanking, with press machine punch extermal form endoporus, assembling spraying and general assembly then.
