Abstract
The utility model relates to a gear-driven four-way multi-bolt synchronous interlocking device for an anti-theft door. The utility model is characterized in that the four directions of a door body are respectively provided with a movable door bolt, and the inner part of the door body is provided with an installing bottom board (also called an assembly bottom board) which is provided with a driving gear and four movable racks engaged with the driving gear, wherein, each rack is respectively and fixedly connected with the four door bolts through a connecting rod, the gear is positively and reversely rotated, the four door bolts can be driven to synchronously do telescopic motions through the connecting rod of the racks so as to accomplish the door locking and the door opening actions. The utility model can be used on all anti-theft doors of dwelling houses or safes, etc. The utility model has the advantages of reasonable structure, high installing precision, flexible and convenient operation, good anti-prizing resistance, safety and firmness.
Description
The utility model relates to a kind of mechanical safety lock manufacturing technology.Particularly a kind of many bolts of gear drive four-way synchronous locking device that can be used on safe door or the security door.
Existing various security door, mostly be mechanical code lock and pellet shot from a slingshot (two tongue) lock as the mechanical security and anti-theft lock of being installed on safe door or the house security door, do not have multi-faceted keeper is set, cause security door easily to be pried open by the thief, security performance is low, again the cabinet door of if any safety cabinet, at most also be that the design of tripartite direction has keeper (adopting lever driven in synchronism bolt), the pick-proof performance is still not high yet.
The purpose of this utility model provides a kind of many bolts of four-way synchronous locking device that adopts gear drive, and it is installed on safe door or other security doors.During use, can further improve the pick-proof performance, have the installation accuracy height, the advantage that safety is firm.
The utility model is to adopt following technical scheme to realize: it comprises a body (be made generally in and be the rectangle doorframe) and cylinder lock (have also be furnished with coded lock), it is characterized in that being respectively equipped with movable keeper at the four direction of door body, be provided with one in door body inside base plate (also claiming the assembly plate) is installed, four movable tooth bars that (driving) gear are installed on this base plate and are engaged with, wherein every toothed rack is fixedly connected with four keepers respectively by connecting rod (push rod) again, the rotating transmitting gear, can drive four keepers by the tooth bar connecting rod and make stretching motion synchronously, to finish the action of locking a door and open the door.
Interlock of the present utility model can use on all security doors such as private residence or safety cabinet, and the use that can match with pellet shot from a slingshot, the coded lock of security door itself, have rational in infrastructure, the installation accuracy height, flexible operation is light, particularly four-way ties lock synchronously more, pick-proof performance height, and security door is more seemed, and safety is firmly.
Below in conjunction with embodiment the utility model is described in further detail.
Accompanying drawing 1 is an assembly structure schematic diagram of the present utility model.
Wherein: 1, door body (doorframe), 2, keeper (also claiming locking bolt), 3, bolt, 4, connecting rod (also claiming push rod), 5, connecting rod locating glooves, 6, locating pin, 7, base plate (assembly plate) is installed, 8, driven wheel, 9, movable tooth bar, 10, tooth bar installing rack, 11, block, 12 mechanical code locks, 13, block, 14, block, 15, cylinder lock.
With reference to accompanying drawing, when the utility model is made in specific design, also have following feature:
One, used driven wheel can be made and be the laminated type gear.So-called lamination gear is meant the tagger punch die is made the sheet gear, then according to required thickness, again by these thickness slices be formed by stacking (accompanying drawing slightly).So just needn't manufacture and design the thick gear of monolithic, can reduce cost, the manufacturing assembling is simpler.
Two, four toothed rack 9 with driven wheel 8 engagements are that rectangular arrangement is installed installing on the base plate 7.
Three, when concrete the manufacturing, keeper can be made and be a bolt one door bolt structure and also can make and be a bolt two door bolt structures (seeing accompanying drawing 1), and it is more firm to seem like this.
The same with the security door of prior art, on tooth bar or keeper seat, also be provided with the pellet shot from a slingshot dead bolt and (or) the coded lock block 13,14 and the block 11 that touch mutually, like this when cylinder lock and (or) when coded lock is not unlocked, barrier effect because of block, driven wheel can't rotate, door just can't be opened, and have only when cylinder lock and (or) after coded lock opened, transmitting gear driving keeper retreat contraction to finish the action of opening the door smoothly.
Claims (4)
1, a kind of many bolts of gear drive four-way synchronous locking device of security door, comprise a body (1) and cylinder lock (15), it is characterized in that being respectively equipped with movable keeper (2) at the four direction of door body (1), be provided with one in door body inside base plate (7) is installed, the four movable tooth bars (9) that a driven wheel (8) are housed on this base plate and are engaged with, wherein every toothed rack is fixedly connected with four keepers respectively by connecting rod (4) again, the rotating transmitting gear, can drive four keepers by the tooth bar connecting rod and make stretching motion synchronously, to finish the action of locking a door and open the door.
2, interlock according to claim 1 is characterized in that used driven wheel (8) can be made and is the laminated type gear.
3, interlock according to claim 1 is characterized in that four toothed rack (9) that mesh with driven wheel (8) are that rectangular arrangement is installed installing on the base plate (7).
4, interlock according to claim 1 is characterized in that keeper can be made and is a bolt one door bolt structure, also can make to be a bolt two door bolt structures.
