Abstract

The utility model relates to a thread memory key. The thread memory key comprises a key hand shank, a key handle and a key core, wherein the key handle is located below the key hand shank, the key hand shank is connected with the key core through triangular threads, and a spring is arranged in a deep hole between the key hand shank and the key core after the key handle is connected with the key core. The thread memory key is simple in structure and convenient to operate; due to the fact that the key handle is connected with the key core through the triangular threads, when the key handle is screwed, the key hand shank moves forward or backward until the key hand shank reaches the end point of the threads; when the key hand shank is rotated to reach the end point of the threads, torque is performed on the key core, so that a door is opened or locked inside; meanwhile, the length of the key changes, after the door is closed, the spring provides pre-tightening force, loosening and sliding are prevented, and therefore whether the door is locked inside or not can be judged through the change of the length of the key.

Description

The thread memory key

Technical field

The utility model belongs to the key technical field, particularly a kind of thread memory key.

background technology

In our daily life, the key life appliance that is absolutely necessary, but As time goes on, traditional key has been difficult to meet people's daily demand.Due to its function singleness, in life, whether people go out and often forget door lock and close,, poor memory fast for the carelessness of doing things, rhythm of life, there is the people of obsession etc. to cause a lot of inconvenience, therefore, need a kind of novel memory key help the state of locking that people judge door lock.

Summary of the invention

The utility model provides a kind of and can help people to judge that door lock locks the thread memory key of state for solving the technical problem existed in known technology.

The technical scheme that the utility model is taked for the technical problem existed in the solution known technology is:

A kind of thread memory key, comprise key handle, the shank of the key and key core, described the shank of the key is positioned at the below of key handle, and described the shank of the key is connected with key core by triangle thread, in the deep hole after described the shank of the key is connected with key core between key handle and key core, is provided with spring.

Advantage and the good effect that the utlity model has are: the utility model is simple in structure, easy to operate, by key handle, with the triangle thread of key core, is connected, when turning the shank of the key, key handle advances or retreats, until the screw thread terminal, when the key handle rotation reaches the screw thread terminal, key core is subject to moment of torsion, opens the door or locks, and key length changes simultaneously, closing behind the door, provide pretightning force by spring, anti-on-slip pine, therefore can judge whether by the variation of key length to lock.

The accompanying drawing explanation

Fig. 1 is that the utility model master looks the sectional structure schematic diagram;

In Fig. 1,1. key handle, 2. spring, 3. key core, 4. the shank of the key.

the specific embodiment;

For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1, a kind of thread memory key, comprise key handle 1, the shank of the key 4 and key core 3, the shank of the key 4 is positioned at the below of key handle 1, key handle 4 is connected with key core 3 by triangle thread, be provided with spring 2 in deep hole after the shank of the key 4 is connected with key core 3 between key handle 1 and key core 3, so that pretightning force to be provided.

The utility model is simple in structure, easy to operate, by key handle 4, with the triangle thread of key core 3, is connected, when turning the shank of the key 1, key handle 4 advances or retreats, until the screw thread terminal, when key handle 4 rotations reach the screw thread terminal, key core 3 is subject to moment of torsion, opens the door or locks, and key length changes simultaneously, closing behind the door, provide pretightning force by spring 2, anti-on-slip pine, therefore can judge whether by the variation of key length to lock.

Certainly; above-mentioned explanation is not limitation of the utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.

Claims

1. a thread memory key, comprise key handle (1), the shank of the key (4) and key core (3), described the shank of the key (4) is positioned at the below of key handle (1), it is characterized in that, described the shank of the key (4) is connected with key core (3) by triangle thread, in the deep hole after described the shank of the key (4) is connected with key core (3) between key handle (1) and key core (3), is provided with spring (2).
