Abstract

The utility model belongs to the technical field of tool to lock key product technology and specifically relates to a key that whether can instruct the door to lock. It has the dextrorotation external screw thread including instructing double -screw bolt, key body in the processing of key body afterbody, instructs the double -screw bolt to close soon on the key body through the screw thread. Lock with key when the door, the convex shoulder of indicateing the double -screw bolt to lie in on key body afterbody and the key body pastes mutually, at this moment opens the door with key, after key inserts the lockhole totally, and recurrence rectilinear movement not, but only be anticlockwise rotation in the lockhole, because the gearing of screw, the instruction double -screw bolt will be linear motion and leave the convex shoulder along the key body. After the lock is opened completely, instruct double -screw bolt and lock tapered end terminal surface to paste mutually. Equally, at this moment reuse key locks a door, after key inserts the lockhole totally, recurrence rectilinear movement not, but only be rotate clockwise in the lockhole because the gearing of screw indicates the double -screw bolt and will be linear motion, arrive the convex shoulder and its paste mutually. The rational design is closed portion thread's pitch, length soon and is instructed the length of double -screw bolt, just can guarantee to instruct after the lock well the double -screw bolt be located convex shoulder on key body afterbody and the key body paste mutually and open the door after instruct double -screw bolt and lock tapered end terminal surface to paste mutually. Like this through look over indicate the double -screw bolt whether with the key body on the mutually sturdy people's door of at present indicateing of convex shoulder whether with the good mesh of key lock.

Description

A kind of key

Technical field

This utility model relates to lockset key product technical field, a kind of key that door can be indicated whether to lock.

Background technology

In daily life, often due to a variety of causes, after people are away from home, cannot be assured that whether door locks (lock and refer to be stretched out by all for lockset dead bolts with key put in place) with key, sometimes have to return and check, sometimes because being pressed for time, to home can not be returned check, the most uneasy.Existing normal key does not have the function indicating door whether to lock to people with key.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in construction to solve the deficiency of the said goods technology, can indicate, to people, the key whether door lock with key.

In order to achieve the above object, the key designed by this utility model, it includes indicating stud, key body, is machined with dextrorotation external screw thread at key body afterbody, and instruction stud passes through threaded engagement on key body.

Technique scheme, utilizes instruction stud position on key body to indicate the most useful key of door to lock.After door is to lock with key, the convex shoulder (see Figure of description) that instruction stud is positioned on key body afterbody and key body is affixed, if not in this position, represents that door does not lock with key, it should go home to lock door.In the technical scheme that this utility model is used, assume that door locks with key, the convex shoulder that instruction stud is positioned on key body afterbody and key body is affixed, at this moment turn the key in the lock, after the fully-inserted lockhole of key, no longer move linearly, but only rotate counterclockwise in lockhole, due to the gearing of screw thread, instruction stud will move along a straight line along key body and leave convex shoulder.After door lock fully opens, instruction stud and door lock end face are affixed.Equally, locking a door with key the most again, after the fully-inserted lockhole of key, no longer move linearly, but only rotate clockwise in lockhole, due to the gearing of screw thread, instruction stud will move along a straight line, and arrives convex shoulder and is also affixed with it.Appropriate design screws the pitch of partial threads, length and the length of instruction stud, it is ensured that the convex shoulder indicating stud to be positioned on key body afterbody and key body after door lock is good indicates stud and door lock end face to be affixed after being affixed and opening the door.So by checking whether instruction stud is affixed, with the convex shoulder on key body, the purpose realizing indicating people's door whether to lock with key.

Key obtained by this utility model, it provides the benefit that simple in construction, easy to use, can intuitively indicate whether door locks with key.

Accompanying drawing explanation

Accompanying drawing is structural representation of the present utility model.

1. key body in figure, 2. screw thread, 3. instruction stud, the 4. convex shoulder on key body (1).

Detailed description of the invention

The utility model will be further described to combine accompanying drawing below by embodiment.

Embodiment 1:

As it can be seen, the key that the present embodiment describes, it includes indicating stud (3), key body (1), instruction stud (3) and key body (1) to be spun together by screw thread (2).Assume that door locks with key, the convex shoulder (4) that instruction stud (3) is positioned on key body (1) afterbody and key body (1) is affixed, at this moment turn the key in the lock, after the fully-inserted lockhole of key, no longer move linearly, but only rotate counterclockwise in lockhole, due to the gearing of screw thread, instruction stud (3) will be done linear motion and leave convex shoulder (4).After door lock fully opens, instruction stud (3) and door lock end face are affixed.Equally, locking a door with key the most again, after the fully-inserted lockhole of key, no longer move linearly, but only rotate clockwise in lockhole, due to the gearing of screw thread, instruction stud (3) will move along a straight line, and arrives convex shoulder (4) and is affixed with it.Appropriate design screws the pitch of partial threads, length and the length of instruction stud (3), it is ensured that the convex shoulder (4) indicating stud (3) to be positioned on key body (1) afterbody and key body (1) after door lock is good indicates stud (3) and door lock end face to be affixed after being affixed and opening the door.So indicate whether people's door locks with key by checking that whether instruction stud (3) is affixed with the convex shoulder (4) on key body (1).

Claims

1. a key, it includes indicating stud, key body, it is characterized in that: be machined with dextrorotation external screw thread at key body afterbody, and instruction stud passes through threaded engagement on key body.
