Abstract
The utility model discloses a transverse linkage multi-position locking anti-theft door, which comprises a door leaf, a door lock, a door frame box and the like. The door frame is provided with a transverse bolt linkage mechanism controlled by a door lock back locking inserted bar 14, the mechanism is provided with an elastic reset movable block, the elastic reset movable block is attached to a bolt which can move transversely on the door frame box through a movable rod piece, the movable edge of the door leaf is provided with a side edge 7, and the side edge is provided with a pin hole 8 corresponding to the bolt. When the door is locked, the reverse lock inserted bar presses the reset movable block to drive the transverse bolt linkage mechanism to enable the bolt to be inserted into the corresponding pin hole on the door leaf to form multi-position locking, and a thief cannot damage the anti-theft door by adopting a door picking method.
Description
The utility model belongs to door and window, and especially Anti-theft door and window is made the field.
Door leaf turnover property destruction when the robber adopts instrument insertion crack between a door and its frame to force open the door, often takes place in the security door of present various metal sheet door leafs.Tracing it to its cause, mainly is because the locking point of the door leaf of present security door and doorframe very little, only depends on door lock to carry out locking at the door leaf middle part, causes opportunity to the burglar.
The purpose of this utility model is a kind of horizontal interlock multidigit locking security door of design, makes it make the burglar can't lever up door leaf in that door leaf and doorframe are formed locking at a plurality of positions, really makes security door play antitheft effect.
The purpose of this utility model is to realize by following design.
On the security door of forming by door leaf, door lock and doorframe box etc., doorframe is provided with the horizontal latch link gear of locking inserted link control with door lock, this mechanism has an elastic reset movable block, the elastic reset movable block amplexiforms mutually by the latch that can move laterally on a movable rod member and the doorframe box, the active edges of door leaf is equipped with the side edge, side along on be equipped with and the corresponding pin-and-hole of described latch.
After adopting design as above, when house-owner leaves home, close security door, and use key rotation lock core, make and lock inserted link and laterally push the Flexible Reset movable block, in the movable block shifting process, the movable rod member on it drives the movable avris of the laterally inserted door leaf of inserted link along last corresponding pin-and-hole.Like this, dead bolt is arranged and lock the inserted link locking except the middle part on the door leaf, other position forms the multidigit locking by latch, and the anti-sled folding ability and the intensity of door leaf are greatly improved.When house-owner reenters, make with key turn lock core and to lock inserted link and laterally return, be subjected to the effect of flexible member, the movable block that resets resets, and the movable rod member on it makes latch translation return, withdraws from the corresponding pin-and-hole of door leaf, and locking is removed.The utility model operation meets people's use habit with to have security door now just the same, and is simple and easy to do.
Description of drawings is as follows.
Fig. 1 is the basic outside drawing of the utility model embodiment 1.
Fig. 2 is the sectional view of the utility model embodiment 1 doorframe box.
Fig. 3 is the K portion sectional view of Fig. 1.
Fig. 4 is the mechanism's state diagram before Fig. 2 locking.
Fig. 5 is the mechanism's state diagram behind Fig. 2 locking.
Fig. 6 is the mechanism's state diagram before the utility model embodiment 2 lockings.
Fig. 7 is the mechanism's state diagram behind the utility model embodiment 2 lockings.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 to Fig. 5 is a kind of embodiment of the present utility model, and in this example, movable rod member is that hank is connected on the lever on the doorframe box.Middle part and Door-lock bolt correspondence position at doorframe box 1 are provided with a horizontal latch link gear.Its concrete formation is, is fixed with an elastic reset movable block 2 in the doorframe box, and this movable block connects with the lever 4 that links on doorframe by hinge 3, and the moving fulcrum 5 of lever is connected on the doorframe box.One end of lever is provided with the latch 6 that can move laterally.The door leaf active edges is equipped with side along 7, side along on be equipped with and the corresponding pin-and-hole 8 of described latch.
When locking a door, close security door, and use key rotation lock core, make and lock inserted link 14 and laterally push Flexible Reset movable block 2, in the movable block shifting process, the movable avris of the laterally inserted door leaf of the lever drives latch on it is along last corresponding pin-and-hole.Like this, except the middle part dead bolt is arranged on the door leaf and lock the bar lever lock closes, other position forms the multidigit locking by latch, makes the anti-sled of door leaf roll over ability and intensity greatly improves.When house-owner reenters, make with key turn lock core and to lock inserted link and laterally return, be subjected to the effect of flexible member, the movable block that resets resets, and the lever on it makes latch translation return, withdraws from the corresponding pin-and-hole of door leaf, and locking is removed.
Adopt basic scheme of the present utility model, can between door leaf and doorframe box, constitute an additional closure point (except that door lock), also can constitute a plurality of locking points.What provide in this legend is the situation with two additional closure points.At this moment, drive two latches by two cover leverages and finish the locking action synchronously.
Implement the power case for one when Fig. 6, Fig. 7 are the utility model with the projection post rod mechanism as movable rod member.One end of elasticity activity resetting block 9 has the curve protuberance, and the lower end of push rod 10 (movable rod member) links to each other with the movable block 9 that resets, and also amplexiform with latch 15 mutually by a curve projection 11 upper end of push rod, on the latch 15 back-moving spring is housed.When locking a door, lock the curve protuberance that inserted link pushes movable resetting block, be subjected to the effect of protuberance curved surface, move and drive curve projection on it on the push rod and push latch and make lateral displacement, latch is inserted in the door leaf pin-and-hole; When unblanking, key rotation lock core is locked the inserted link return, under spring 12 effects, and the push rod return, latch resets under the effect of spring, withdraws from the door leaf pin-and-hole and removes locking.
Adopt basic scheme of the present utility model, when implementing, also can set up some auxiliary safeguard procedures, as shown in Figure 5, can near the movable avris of door leaf edge, the sight shield 13 of covering crack between a door and its frame be set.When door was closed, the backplate door was lived the slit between door leaf and doorframe box, and the burglar can't be inserted instrument in the crack between a door and its frame, had further strengthened safeguard function.
Adopt basic scheme of the present utility model, can also make multiple concrete structure in force.Movable rod member also can adopt some to be equal to means and do conventional substituting.
