Abstract
The utility model discloses a movable door catch which comprises three segments of structures, namely a middle segment and two opening-closing segments. The two opening-closing segments are respectively matched with the middle segment in an articulating manner, one of the two opening-closing segments is matched with a lock catch arranged on an indoor door plate in a lap-joint manner, and the other of the two opening-closing segments is matched with the lock catch arranged on an outdoor doorframe in a lap-joint manner; the middle segment is arranged in a gap between a door and the doorframe in a penetrating manner, and the thickness of the articulating part of the middle segment and the opening-closing segments is larger than that of the non-articulating part. When the door is locked outdoors, a person indoors can also open the door catch and freely go in and out; likewise, when the person indoors closes the door catch, the person outdoors can also unlock the door and go in.
Description
Technical field
The knocker device of using when the utility model relates to a kind of locking a door.
Background technology
Along with the development of society, the mode of locking a door is also varied, and wherein, the mode of locking a door with knocker is extensive use of by people because of its convenience economic and practical always.
At present, knocker commonly used generally includes canned paragraph and folding section, folding section and canned paragraph through hinge hinged-be that canned paragraph and folding Duan Junke relatively rotate around hinge.Canned paragraph is fixed on the door-plate through fixtures such as screw or nails, have the hole on the folding section, with the snap close of knocker overlap joint in described hole, snap close is fixed on the doorframe, thereby lockset passes described hole the folding section of knocker is fixed on the snap close, thereby door-plate is locked on the doorframe.
But the knocker of form of structure like this, indoor nobody the time, just with the knocker locking, when everybody was in, knocker was not locked and is closed the door by the mode at indoor plug in bolt, such shortcoming is: on the one hand, it can only be at outdoor unidirectional unlatching or locking, and when outdoor knocker and snap close being fixed at closing time, indoor people just can't come out, after must knocker being opened by outdoor people, indoor people just can come out; On the other hand, when the people who returned that night goes home,, will certainly wake up so in the tame talent conference inlet chamber because indoor people has plugged bolt and closed the door.Existing knocker form has brought serious inconvenience for people's life, incompatibility people's life requirement more and more.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of movable knocker, adopt the utility model, when outdoor locking, indoor people also can open knocker and freely come in and go out, and same, when indoor people was closed blind catch, outdoor people also can unblank to enter.
The utility model is achieved through the following technical solutions:
A kind of movable knocker, it is characterized in that: comprise three-stage structure, be respectively interlude and two folding sections, the hinged cooperation of the described interlude of two folding Duan Junyu, one of them folding section cooperates with snap close overlap joint on being arranged on indoor door-plate, another folding section cooperates with snap close overlap joint on being arranged on outdoor doorframe, and interlude runs through in the slit between described and the doorframe, and the thickness of described interlude and folding section hinged place is greater than the thickness of non-hinged place.
The width of described interlude is greater than the width of described folding section.
Have the hole on the described folding section, the snap close that cooperates with folding section overlap joint runs through in the described hole.
The beneficial effects of the utility model show:
Compared with prior art, because the utility model adopts three stage structure, one of them folding section cooperates with snap close overlap joint on the indoor door-plate, another folding section cooperates with snap close overlap joint on being arranged on outdoor doorframe, interlude is in the slit between door and the doorframe, such frame mode has been realized the technique effect of " when outdoor locking; indoor people can open knocker and freely come in and go out; same; when indoor people is closed blind catch; outdoor people also can unblank to enter ", and the utility model adopts " thickness of interlude and folding section hinged place is greater than the thickness of non-hinged place " such frame mode, can strengthen the connection reliability of hinged place, further prolong the physical life of whole knocker.Simultaneously, the width of the utility model by interlude is set to the mode greater than the width of folding section, can reduce the wearing and tearing of interlude, increases the service life.
Description of drawings
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments, wherein:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a vertical view among Fig. 1
Mark among the figure:
1, folding section, 2, interlude, 3, the hole, 4, the hinged place, 5, width.
The specific embodiment
With reference to Figure of description, the utility model discloses a kind of movable knocker, this doorway comprises two folding sections 1 and an interlude 2, two folding sections 1 and interlude 2 are all through the hinged cooperation of hinge, can relatively rotate between folding section 1 and the interlude 2, in long-term use, drawn bad in order to prevent hinged place 4, strengthen its resistance to tension, the thickness of hinged place 4 is set to thicker than the thickness of non-hinged place, application life that like this can enhancing activity knocker, in addition, the width 5 of interlude 2 is also wide than the width 5 of folding section 1, also is in order to strengthen antiwear property, to increase the service life.
During use, fix a snap close on the indoor door-plate, fix a snap close on the outdoor doorframe, one of them folding section 1 is overlapped on the snap close on the indoor door-plate, another folding section 1 is overlapped on the snap close on the doorframe, to be positioned at indoor folding section 1 at ordinary times overlaps on the snap close that is fixed on the door-plate, when going out, to be positioned at outdoor folding section 1 is overlapped on the snap close on the doorframe, pin with lockset then, when indoor people need go out, directly open indoor folding section 1 and can open door and free in and out, when outdoor people need enter, directly opening outdoor folding section 1 can enter.
