Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

An embodiment of the invention provides a reminder for preventing forgetting to take a key, and as shown in fig. 1 to 7, the reminder is arranged on one side of a security door close to a door handle. And the security door is generally opened outwards. Comprising a box body 1. In addition, the push rod 2 and the return spring 7 which can move in the box body 1 are also included. One end of the push rod 2, which is positioned outside the box body 1, is provided with a baffle plate. The baffle is made of rubber. The baffle plate is pressed against the inner side of the doorframe by the elasticity of the return spring 7, and the other end of the push rod 2 is provided with a convex block 11. The bump 11 is hemispherical. The hemispherical structure allows smooth separation between the protrusions 11 and the recesses 9.

The return spring 7 is provided with a push block 8 near one end of the convex block 11, and the convex block 11 and the push block 8 are mutually extruded and contacted. The invention also comprises a telescopic rod 3, wherein the telescopic rod 3 is arranged in the return spring 7 and is connected with the push block 8. When the reminder is started, the push rod 2 is propped against the inner side of the doorframe by the elasticity of the return spring 7. When the personnel opened the door, push rod 2 released for the burglary-resisting door limit goes out a branch more, and personnel just can not close the door, and then reminds personnel to take the key.

The invention also comprises a movable block 10 for inserting a key, wherein the movable block 10 is arranged on the front surface of the box body 1. The movable block 10 is provided with a key opening 14. A person may insert a key into the movable block 10 through the key opening 14.

In addition, a spring 5, a support rod 6 and a groove 9 are included. The spring 5 is provided on the inner wall of the back of the case 1. One end of the support rod 6 is connected with the spring 5, and the other end is connected with the movable block 10. The supporting rod 6 is provided with a groove 9 for the return spring 7 to pass through. The length of the push block 8 is matched with the size of the groove 9.

When a person pulls out the key and keeps the key, the push rod 2 is pushed back by one hand, the movable block 10 is pulled out by the other hand, the support rod 6 moves outwards, the groove 9 and the push block 8 are staggered, then the separation of the reset spring 7 and the push rod 2 is completed, and the push rod 2 cannot be extruded towards the inner side of the door frame at the moment.

When the person returns home, the key is simply inserted into the movable block 10. The spring 5 is pressed, and the return spring 7 is contacted with the push rod 2 again, so that the reminder is restarted.

In addition, the support rod 4, the transverse plate 13, the shifting piece 12 and the notch 15 are also included. The notch 15 is provided at the top of the cabinet 1. The shifting sheet 12 and the transverse plate 13 can be freely detached from the box body 1. The paddle 12 is disposed on one side of the slot 15. One end of the supporting rod 4 is arranged in the box body 1 and is fixedly connected with the push rod 2, and the other end of the supporting rod passes through the notch 15 and extends to the outer surface of the top of the box body 1 and is connected with the transverse plate 13. The transverse plate 13 and the pick 12 can contact each other. When a person opens the door, the push rod 2 moves to drive the transverse plate 13 to impact the shifting piece 12, so that a sound is emitted to remind the person to carry a key. The effect of supplementary warning has been played, and this project organization has still solved when the reminiscences installs on the burglary-resisting door of inwards opening moreover, and the problem of how to remind personnel to carry the key.

The working principle is as follows: when in use, the reminder is firstly glued near the anti-theft door handle, and then the key is inserted into the key opening 14, and the push rod 2 is pushed out and is pressed against the inner side of the door frame. When a person opens the door, the push rod 2 extends outwards, so that the door cannot be closed, and the person is reminded to carry the key. After taking the key, a person uses one hand to push the push rod 2 back, uses the other hand to pull out the movable block 10 outwards, and moves outwards through the support rod 6 to stagger the groove 9 and the push block 8, so that the separation of the reset spring 7 and the push rod 2 is completed, and at the moment, the push rod 2 cannot be extruded towards the inner side of the door frame. And the movement of the push rod 2 drives the transverse plate 13 to impact the shifting sheet 12, so that the sound is generated, and the person is reminded to carry the key again.

In conclusion, the reminder capable of preventing forgetting to take the key is installed above or below the door handle optimally, and through the matching of the reset spring 7 and the push rod 2, when a user pushes the door outwards, the push rod 2 can be ejected out, so that the door cannot be closed, and the user is reminded to carry the key. Compared with other electromagnetic key reminders, the reminder is purely mechanical in structure, so that the reminder is higher in durability, does not need to be replaced by a power supply, and is lower in cost. Especially, when many people live in, the electronic reminder reminds people to carry keys through sound, the sound emitted by the electronic reminder is large and the calling time is long, so that the sleep of another person is easily influenced, and unnecessary troubles are caused.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
