Description

Device for preventing forgetting to take key when going out

Technical Field

The utility model relates to a device for preventing forgetting to take a key when going out.

Background

Forgetting to take a key when going out is a problem encountered by many people. This problem causes great inconvenience to our lives, sometimes because of forgetting to bring a key, the person cannot enter the house in time, and even very serious consequences can be caused. The existing device for preventing forgetting to take the key mostly uses the additional functions of the lock body, such as the modes of matching with a sensor, sound and light reminding and the like, see the Chinese patent CN105041045A, and the mode can play a role in preventing forgetting to take, but has higher cost, and part of old door locks cannot be replaced, so that the device is difficult to popularize and use.

Disclosure of utility model

The utility model aims to solve the technical problem of providing a device for preventing a user from forgetting to take a key when going out, which is used for reminding the user when going out by accommodating the key and being arranged near a door handle.

In order to solve the technical problems, the utility model provides a device for preventing a user from forgetting to take a key when going out, which comprises a vertically arranged base, wherein a strip-shaped block which runs forwards and backwards is arranged on the front side of the base, a key slot is arranged on the front end surface of the strip-shaped block, the thickness of the base along the front and back direction is m, the length of the strip-shaped block along the front and back direction is n, and the length of the strip-shaped block along the front and back direction is more than or equal to 2cm and less than or equal to 4cm.

For the sake of simplicity, the device for preventing the user from forgetting to take a key when going out is simply referred to as the device.

The using method and the advantages of the device are that: for the handle type lock body, install this device in the door leaf inboard, its base is located the fan-shaped region that the handle rotated and sweeps, wherein the front end and the handle of rectangular shape piece are along forward and backward direction distance being close, but do not influence the handle and normally rotate, after opening the door with the key, get into in the room, can insert the key slot with the key head, the key handle exposes outside the key slot, the key handle that surpasss this device rectangular shape piece is located handle pivoted orbit just at this moment, influence the normal rotation of lock body handle, namely when the handle is opened the door to the needs to rotate before going out, just can normally rotate the handle and open the door, the key has been held in the handle when rotating the handle and open the door like this, the condition of forgetting to take the key of going out has just stopped in the handle, moreover this device simple structure, the cost is cheap, convenient to use does not have any study cost on the use.

The device is arranged on the handle on the inner side of the door leaf, so that when the handle is rotated to open the door, a key inserted into the key slot of the device can be seen and touched, and reminding and preventing forgetting can be achieved.

In order to achieve better use effect of the device, the preferable scheme is as follows:

preferably, the base is a magnet body or a sucker.

The base adopts the magnet body, and the sucking disc makes things convenient for this device direct absorption on the door leaf medial surface.

Preferably, a double-sided adhesive tape is preset on the rear side of the base.

For the door leaf adsorbed by the magnet or the sucker in no aspect, the preset double faced adhesive tape can be adhered to the inner side surface of the door leaf.

Preferably, the strip-shaped block is made of elastic material, and the slot width of the key slot is gradually narrowed from front to back.

The slot width gradually narrows from front to back and can adapt to keys with various thicknesses, and the key can be stably clamped through elastic deformation when the key is inserted by matching with the strip-shaped block made of elastic materials.

Detailed Description

Referring to fig. 1-5, a device for preventing forgetting to take a key when going out comprises a vertically arranged base 1, wherein a strip-shaped block 2 running back and forth is arranged on the front side of the base 1, the strip-shaped block 2 is made of elastic materials, a key slot 3 is arranged on the front end face of the strip-shaped block 2, the slot width of the key slot 3 is gradually narrowed from front to back, the thickness of the base 1 along the front and back direction is m, the length of the strip-shaped block 2 along the front and back direction is n, and m+n is less than or equal to 2cm and less than or equal to 4cm.

The using method and the advantages of the device are that: for the handle type lock body, the device is arranged on the inner side of the door leaf, the base can be a magnet body and a sucker, the base is arranged on the inner side of the door leaf in an adsorption mode, the base can be a conventional block body, the base 1 is adhered to the inner side of the door leaf through double-sided adhesive tape preset on the rear side, the base 1 is located in a fan-shaped area swept by rotation of the handle 4, the front end of the long bar block 2 is close to the handle 4 along a front-back distance, normal rotation of the handle 4 is not affected, after a door is opened by a key, the head of the key can be inserted into the key slot 3, the key handle 5 is exposed outside the key slot 3, and at the moment, the key handle 5 exceeding the long bar block 2 of the device is just located on the rotating track of the handle 4, so that the normal rotation of the lock body handle 4 is affected, namely, when the handle 4 needs to be rotated to open the door before the door is released, the handle 4 can be normally rotated, and thus the key is held in the door when the handle 4 is rotated to open the door, the situation of forgetting the door is avoided.

Referring to fig. 6, the device is further installed on the handle 4 at the inner side of the door leaf, so that when the handle 4 is turned to open the door, a key inserted in the key slot 3 of the device is necessarily seen and touched, and reminding and preventing forgetting can be achieved.
