Description

Door for protective purpose

The utility model relates in the fixed building protective door in door and lock technology field, includes keeper, has the controlling organization that contains lock body that doorframe, door leaf, handle, the control keeper in keeper hole move.

At all kinds of protective doors, especially in the metal protection door, common employing is directly located with the various keeper of lengthening in each orientation of door and is closed door, and controlling organization comprises revolving member such as the rolling disc that connects handle and keeper, and has comprised the lockset of control revolving member or keeper.A kind of cipher counter that can buy on the market for example, also claim safety cabinet, except that coded lock, there is a rolling disc connecting keeper up and down in the back of door leaf, bossy body is arranged on one of keeper, there is a drawer-lock to install near bossy body, dead bolt can not eject automatically, must use the key turn, dead bolt is stretched out or return to contact with bossy body or throw off, again in company with the action of coded lock and handle, realize the opening-closing process of door in addition.And for example the patent No. is 912301228 multi-faceted locking security door, and more above-mentioned cipher counter the design of revolving member is had improvement, but keeper is identical with the combination of dead bolt, and dead bolt the place ahead all has only one deck iron sheet door; A kind of door in back has been made double-deck door leaf, and keeper and controlling organization are all among interlayer.Above technology exists keeper and enters the situation that all can not automatically lock behind the keyhole on the doorframe, and the user is inconvenience to some extent, and the dead bolt position is comparatively fragile, and double-deck door leaf makes cost up.

The purpose of this utility model is: disclose the protective door that a kind of keeper automatically locks, overcome the deficiencies in the prior art part.

Technical solution of the present utility model is: a kind of protective door, and the controlling organization that contains lock body that has doorframe, door leaf, handle, the control keeper in keeper, band keeper hole to move is characterized in that described keeper includes keeper and laterally keeper up and down; Laterally the latter half of of keeper is the sliding connector that has chute, pressure plates, dead bolt plate washer, and laterally keeper latter half of has the dead bolt plate washer, and first half has a bolt head at least.Laterally keeper can be along guiding and locating piece piece left and right displacement; Laterally on the lock of the below of keeper lock body is housed, when opening the door, dead bolt is pressed against plate and is pressed in the lock body, at closing time, laterally keeper moves to the doorframe direction, dead bolt loses compacting, automatically ejects under the effect of lock body inner spring and stops it to retreat near the pressure plates side, and the dead bolt plate washer is in the dead bolt dead ahead; The keeper cover is put in the guiding square tube that is fixed on the back-up block up and down; Controlling organization has one to be contained on the door, is subjected to manual rolling disc, and it is flexibly connecting keeper and laterally keeper up and down; Described controlling organization concentrates in the can that has a lock-bit hole, and can is contained on the door leaf back side.

Because the utility model: close behind the door along with keeper enters keyhole, dead bolt ejects the locking keeper automatically, and needn't use key again; The place ahead of dead bolt has increased plate washer can prevent that external force from stirring dead bolt after punching on the door leaf; The installation of can replace the internal layer iron sheet, comprehensive said structure characteristics, the utlity model has easy and simple to handle, good reliability, the advantage that saves material.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

Fig. 1 protective door is one of view behind the door

Fig. 2 protective door is two (block surface of can removes) of view behind the door

The controlling organization lateral view of Fig. 3 protective door

This embodiment is that the protective door that a kind of family and office are suitable for also claims security door, technical solution is summarized the statement structural relation, and in the present embodiment, lock body (21) has spring in being, the common door built-in lock body that dead bolt (32) can be pressed into or eject, what embodiment selected for use is the ox head board; Up and down keeper (3), laterally be that pin (17) passes slide block (14) and sliding connector (24) and realizes to bolt (4) and being connected of rolling disc (15); Between sliding connector (24) and the bolt head (10) with screw (34) connect together the general designation horizontal keeper (4), pressure plates (20) is the iron block of a L type; Can (33) is installed on gripper shoe (18) and the locating piece (23), the cage knob (11) in lock-bit hole (2) on the visible lock body (21).

By Fig. 2 and the visible keeper (3) up and down of Fig. 3, horizontal keeper (4) locking that do not put in place, need at closing time, no matter in door leaf (9) or outside control handle (7a) or (7b), rolling disc (15) rotates, keeper (3) upwards moves down respectively simultaneously up and down, laterally keeper (4) moves to doorframe (8) limit, each keeper all enters each keyhole (35) on the doorframe, follow horizontal keeper (4) displacement closely, automatically eject near pressure plates (20) side under the former spring action of dead bolt (32) in lock body (21) that suppressed by pressure plates (20), stop horizontal keeper (4) and up and down keeper (3) withdraw from keyhole (35), realize that the Three-bearing keeper automatically locks.Dead bolt baffle plate (19) is welded on the afterbody of sliding connector (24), behind its displacement one segment distance, is in dead bolt (32) the place ahead.Fig. 1 is the situation behind the normal locking, but can blocks internal construction.In the time of need opening the door, at first twisting cage knob in door leaf (9) or is used the key turn outdoors, again control handle (7a) or (7b) can open the door.

Also have two prior aries with this enforcement is used, the one, hinge one side near door has two fixedly keepers (12), at closing time, enters keyhole (13); The 2nd, implemented another patent lock core protective cover of patent applicant simultaneously in the front of lock core (30), the patent No. 922145695.Make protective door more solid and reliable.

Except the above embodiments, in same inventive concept, can design various embodiments, all can change as the shape of the syndeton of shape, each keeper and the rolling disc of the structure of horizontal keeper, pressure plates, dead bolt plate washer and installation etc.Lock body also can change into controlling and go up or following keeper.

Material selection of the present utility model is simple, and implementation processes such as manufacturing process also are complete feasible ground for common engineers and technicians.Remove shown in the accompanying drawing outdoors, can also produce adapt to safety cabinet, storehouse, or the like the protective door that uses of occasion.
