Description

Technical Field

[0001] The utility model relates to an intelligent door lock, in particular to a keyhole protection handle for an intelligent door lock. Background Art

[0002] With the continuous improvement of living quality, more and more families adopt intelligent door locks. Intelligent door locks generally use fingerprints, passwords and other methods to unlock. However, according to national regulations, intelligent locks should be equipped with emergency mechanical keys. Most of these keyholes are exposed and have no concealment; the exposed keyholes result in low anti-theft performance, and are easily contaminated, corroded by the outside world or blocked by foreign objects, which affects the normal use of the door lock or shortens its service life. To solve this problem, there are two methods on the market. One is to hide the keyhole with a handle. When using the key to open the door, the handle needs to be rotated to expose the keyhole. This structure is relatively complex. And since the handle and the intelligent door lock are slidable, for aesthetic reasons, it is necessary to ensure that the gap between the handle and the intelligent door lock is small and uniform, so higher production processes are required, such as precision carving, and the production cost is high; the other is to use a handle to cover the keyhole, that is, from the front view, only the handle can be seen, and the keyhole cannot be seen. A through hole is provided at the position corresponding to the keyhole on the handle, and a detachable plugging member is installed in the through hole. At the same time, in order to cover the keyhole, a corresponding cover plate is installed on the intelligent door lock. When the key is needed to open the door, the plugging member and the cover plate are removed, and the key can be inserted into the keyhole through the through hole. Compared with the first structure, this structure has more exposed parts, such as the cover plate, and the appearance is relatively complicated. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a keyhole protection handle for an intelligent door lock.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A keyhole protection handle for an intelligent door lock includes a mounting base for mounting on the surface of the intelligent door lock. The mounting base covers the keyhole of the intelligent door lock. A handle part is installed on the side of the mounting base away from the intelligent door lock. A channel with the same axis as the keyhole is arranged in the mounting base. A through hole with the same axis as the channel is arranged on the handle part. A detachable plugging member is installed in the through hole. The mounting base is provided with a resetable push rod for pushing out the plugging member.

[0006] An installation cavity is arranged in the mounting base, and the push rod is slidably installed in the installation cavity.

[0007] A through hole is arranged on the side of the installation cavity away from the channel, and one end of the push rod extends out from the through hole.

[0008] A first notch portion is provided on the side wall of the through hole close to the installation cavity. A folding portion is provided on the push rod corresponding to the push rod. The folding portion is slidably installed in the first notch portion, and the end of the folding portion abuts against the plugging member.

[0009] A first inclined surface portion is provided at the end of the folding portion. A second inclined surface portion is provided on the plugging member corresponding to the first inclined surface portion. The first inclined surface portion and the second inclined surface portion are in abutment.

[0010] A return spring is sleeved on the outer side of the push rod; symmetrically arranged protruding portions are provided on both sides of the push rod. An extension portion extends from the protruding portion towards the direction of the channel. A second notch portion is formed between the extension portion and the push rod. One end of the return spring abuts against the outer wall of the channel, and the other end abuts against the bottom of the second notch portion.

[0011] The folding portion extends out of the outer side from one of the gaps of the return spring from the side of the return spring.

[0012] An annular groove is provided on the side wall of the through hole. A flexible ring is sleeved on the outer side of the plugging member. The flexible ring is embedded in the annular groove.

[0013] The beneficial effects of the present utility model are as follows: In the present utility model, the installation base covers the keyhole of the intelligent door lock. A handle portion is installed on the side of the installation base away from the intelligent door lock. A channel with the same axis as the keyhole is provided inside the installation base. A through hole with the same axis as the channel is provided on the handle portion. A detachable plugging member is installed in the through hole. The installation base is provided with a resetable push rod for pushing out the plugging member. After the plugging member is pushed out by the push rod, the key can be used to pass through the through hole and the channel and insert into the keyhole to achieve the effect of mechanical unlocking. Using the installation base to shield the keyhole can cancel the existing cover plate for shielding the keyhole, which is not only more concise and beautiful in appearance, but also can reduce the types of materials and lower the production cost.
