Abstract

The utility model relates to a marble type memory key which comprises a key handle and a key core. The key handle is provided with a key handle body, and a key shell is arranged on the lower portion of the key handle body. Two key shell blocking pieces are arranged on the inner side of the key shell, and a key main core part of the key core is connected with the interior of the key shell. Two key core blocking pieces are arranged on the outer side of the key main core part, and the key core blocking pieces and the key shell blocking pieces interact. The key main core part is further provided with a horizontal spring which is connected with a steel ball, and the key shell opposite to the steel ball is provided with two holes, wherein the center lines of the two holes are located in the same horizontal plane. The word 'open' and the word 'close' are arranged near to the two holes respectively. The marble type memory key is simple in structure and convenient to operate; the key shell is matched with a marble, so that the word 'open' and the work 'close' beside the holes of the key shell are observed, the state of a door lock can be shown, people can conveniently observe the back-locking state of the door lock outside the key, and the problem that people in life forget whether the door lock is back locked or not when going out is well solved.

Description

Ball bead type memory key

Technical field

The utility model belongs to the key technical field, particularly a kind of ball bead type 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 ball bead type 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 ball bead type memory key, comprise the shank of the key and key core, described the shank of the key is provided with key handle, described key handle bottom is provided with the key shell, described key shell inboard is provided with two key shell catch, connect the key master core segment of key core in the key shell, the outside of described key master core segment is provided with two key core catch, described key core catch and key shell catch interact, also be provided with crossed strip on the main core segment of described spoon, be connected with steel ball on described spring, the key shell relative with described steel ball is provided with two holes, the center line in described two holes is positioned on same level, be respectively equipped with " opening " near described two holes, " close " printed words.

On described key shell, the diameter in hole is less than the diameter of steel ball.

The line of centres of the line of centres in described two holes and two shell catch is perpendicular.

Described two key shell catch are interspersed, be arranged at the upper and lower both sides of horizontal center line of key shell, described two key core catch are interspersed, be arranged at the upper and lower both sides of horizontal center line of key master core segment, when key core catch and key shell catch are interacted, the angle of rotation is not more than 180 °.

Advantage and the good effect that the utlity model has are: the utility model is simple in structure, easy to operate, by the key shell, with hoodle, coordinate, when turning key to the respective aperture position, hoodle is stuck in position, corresponding hole, " opening " by key shell aperture side " closes " printed words, show door lock is in which kind of state, be convenient for people to from the state of locking of key visual observation door lock, solved preferably people in life and forgotten the problem whether door lock is locked while going out, give careless, rhythm of life is fast, poor memory, have the crowd of obsession etc. to bring convenience.

The accompanying drawing explanation

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

Fig. 2 is Fig. 1 side-looking sectional structure schematic diagram;

Fig. 3 is that Figure 1A-A is to the view enlarged drawing;

Fig. 4 is that Figure 1B-B is to the view enlarged drawing.

In Fig. 1～Fig. 4,1. the shank of the key, 101. key handles, 102. key shells, 103. key shell catch, 2. key core, 201. key master core segments, 202. key core catch, 203. springs, 204. steel balls.

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～Fig. 4, a kind of ball bead type memory key, comprise the shank of the key 1 and key core 2, be provided with key handle 101 on the shank of the key 1, key handle 101 bottoms are provided with key shell 102, key shell 102 inboards are provided with 103, two key shell catch 103 of two key shell catch and are interspersed, and are arranged at the upper and lower both sides of horizontal center line of key shell 102.The interior connection key core 2 of key shell 102, key master core segment 201 outsides of key core 2 are provided with two key core catch 202, two key core catch 202 are interspersed, be symmetricly set in the upper and lower both sides of horizontal center line of key master core segment 201, the horizontal center line of key shell (102) overlaps with the horizontal center line of key master core segment 201, key core catch 202 interacts with key shell catch 103, makes key master core segment 201 and key shell 102 that counterrotating angle occur and is not more than 180 °.The upper crossed strip 203 that also is provided with of the main core segment 201 of spoon, be connected with steel ball 204 on spring 203, be provided with two holes on the key shell 102 relative with steel ball 204, the center line in two holes is positioned on same level, be respectively equipped with " opening ", " closing " printed words near two holes, bore dia is less than steel ball 204 diameters, can realize that steel ball 204 not exclusively ejects and normal the retraction, and the line of centres of the line of centres in two holes and two shell catch 103 is perpendicular.

The utility model is by the shank of the key 1 as basis, and the B-B from the A-A of Fig. 3 to view enlarged drawing and Fig. 4 can find out the detailed structure of key to the view enlarged drawing.Reach and lock and fully while opening when turning key, with key master core segment 201, relative rotation occurs by key shell 102, on forwarding key shell 102 to during the position in hole, steel ball 204 not exclusively ejects under the active force of spring 203, when key master core 201 turns on shell 102, key shell 102 is temporarily fixing with key master core segment 201.When steel ball 204 ejects in certain hole, " close " printed words according to " opening " near hole on key shell 102, judge key is in which kind of state, thereby realize its function.The utility model is the interaction with key core catch 202 by key shell catch 103, can prevent from making the key at most can only Rotate 180 ° before the actual work of unblanking because lock too tightly makes the clamping force between steel ball 204 and key shell 102 cause not key to surpass the rotation of 180 °.

The utility model is simple in structure, easy to operate, by the key shell, with hoodle, coordinate, when turning key to the respective aperture position, hoodle is stuck in position, corresponding hole, " opening " by key shell aperture side " closes " printed words, show door lock is in which kind of state, be convenient for people to from the state of locking of key visual observation door lock, solved preferably people in life and forgotten the problem whether door lock is locked while going out, give careless, rhythm of life is fast, poor memory, have the crowd of obsession etc. to bring convenience.

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.
