Abstract

The invention discloses a key frame preventing a user from forgetting to take a key. The key frame preventing the user from forgetting to take the key is composed of a frame body, a backstop and a rotating connecting piece. The frame body is a rectangular frame. The rotating connecting piece is arranged at one end of each long edge of the frame body and is connected with the two ends of a key handle so that the key can rotate in the frame body. The backstop is fixedly connected to the frame body or the backstop and the frame body are connected into a whole. The backstop is used for rotation locating of the key so that the key and the frame body can form an included angle after rotation locating, and the backstop is used for preventing the user from retracting the hand after a door is opened. The user is effectively reminded of pulling put the key. According to the key frame preventing the user from forgetting to take the key, a door lock does not need to be changed, an electronic device is not needed either, and therefore the key frame preventing the user from forgetting to take the key is simple and practical.

Description

Prevent forgetting to get key frame

Technical field

The present invention relates to one way of life articles for use, is specifically after a kind of prevention is opened the door, to forget to take away the apparatus of key.

Background technology

Turning the key in the lock is ordinary affair during people live, yet after opening the door, by key forgetting, the thing in lockhole happens occasionally, particularly children and old man, and this situation is more prone to.Given this, occurred that some invention hope address this problem, and are no lack of some outstanding designs, but most of design all realizes by transformation door lock internal construction, as Chinese patent literature, publication number is the patent of CN2515376Y, CN2289019Y, CN2695554Y, CN201202319Y.Chinese patent literature, publication number is the patent of CN201924666U, a kind of method that realizes its function by transformation key is disclosed, advantage is just can realize corresponding function without transformation door lock internal construction, have more by contrast superiority, but this invention must increase warning device on the key, and triggering, warning device need be placed in the shank of the key, cause the shank of the key volume to increase many, must be manufactured specially by factory simultaneously.

Summary of the invention

The object of the invention is: for the problems referred to above, proposed a kind ofly anti-to forget to get key frame, after opening the door key frame opponent return barrier effect, thereby can prevent key forgetting in lockhole.

The present invention addresses the above problem taked technical scheme: a kind ofly anti-forget to get key frame, framework, backstop, rotating connector, consist of.Described framework is an elongate frame, in one end, the long limit of framework, is provided with described rotating connector and connects with the shank of the key two ends, and key can be rotated in framework.Described backstop is fixedly connected in described framework or with framework and is integrated, and for the rotation location to key, makes with framework shape, to have angle behind key rotation location, and after opening the door, returning of opponent played barrier effect.

Described rotating connector is the key fixture with rotating shaft, hinged with framework after key can being fixed.

Described rotating connector is rotating shaft, directly hinged with the shank of the key.

The invention has the beneficial effects as follows: the returning of opponent after opening the door of the framework after outwarding winding played barrier effect, effectively reminds user to extract key.Do not need to change door lock, do not need electronic installation yet, simple, practical.

Triggering, alarming apparatus are arranged in key cover, are convenient to make, and have a style of one's own, and general door key can be used, and packs into or take out all very convenient.

Fig. 6 is the side sectional view of this use new embodiment 2 while outwarding winding key.

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6,1. framework, 2. backstop, 3, rotating connector, 3a key cover, 3b. upper shield, 3c. screw, 3d. is flexible coupling, 3e. fixed screw, 3f. front opening, 3g. open rearward end, 3h. rotating shaft, 4. key, 4a. key bit, 4b. the shank of the key, 5. hanging hole, 6. contact surface, 7. catch.

Body front end has an opening, for key bit, passes, and on key bit side, body has a through hole, for passing the trigger head of described trigger.There is an opening body rear end, for packing the shank of the key into.Described bonnet is used for covering body open rearward end, and is connected with described body by described connector.At described body and keyhole correspondence position, have through hole, facilitate suspension member to be inserted in.

Described connector is to be separately positioned on being flexible coupling of bonnet end positions to be connected with screw, for bonnet being connected to body rear end.

The specific embodiment

The present invention gives explanation by two embodiment.

The first embodiment as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4.Rotating connector 3 is comprised of key cover 3a, upper shield 3b, screw 3c, the 3d that is flexible coupling, fixed screw 3e, front opening 3f, open rearward end 3g, rotating shaft 3h.Key cover 3a is flat-shaped cavity, and door key 4 packs into by key cover 3a open rearward end 3g, and key bit 4a stretches out by front opening 3f.Pack into after key 4, upper shield 3b is connected with fixed screw 3e by the 3d that is flexible coupling with key cover 3a, covers key cover 3a open rearward end 3g.

Framework 1 is an elongate frame, in one end, the long limit of framework 1, by rotating shaft 3h, is connected with above-mentioned rotating connector 3 two ends, makes the key 4 can be in the interior rotation of framework 1.Framework 1 lower end is fixedly connected with a bar shaped backstop 2, for the rotation location to key 4, make with framework 1 shape, to have angle (as Fig. 4) behind key 4 rotation location, after opening the door, returning of opponent played barrier effect, meanwhile, this backstop 2 has also played the positioning action of key 4 playback.Described framework 1 is provided with hanging hole 5, is convenient for carrying.

The second embodiment is as shown in Fig. 5, Fig. 6.Rotary connector 3 is a rotating shaft.Framework 1 is an elongate frame, in framework 1 one end, by rotary connector 3, is connected with the shank of the key 4b, makes the key 4 can be in the interior rotation of framework 1.The effect of backstop 2 is played in framework 1 upper ledge lower end simultaneously with the contact surface 6 of key 4, for the rotation location to key 4, make with framework 1 shape, to have angle (as Fig. 6) behind key 4 rotation location, and after opening the door, returning of opponent played barrier effect.Catch 7 plays the positioning action of key 4 playback.Described framework 1 is provided with hanging hole 5, is convenient for carrying.

The course of work of technical scheme proposed by the invention is: open the door before lock, key 4, with rotary connector 3 rotations, rotates to by backstop 2 or upper ledge contact surface 6 normal keies 4, and key 4 has angle with framework 1 shape.While opening the door, hold framework 1, simultaneously, forefinger and thumb pinch key cover 3a or the shank of the key 4b opens the door key bit 4a insertion lockhole, if do not take out key 4 after opening the door, barrier effect is played in returning of framework 1 opponent, only extracts key 4, hand could be return smoothly, realizes prevention user key 4 is forgotten in lockhole.
