Description

Fingerprint lock

Technical Field

The utility model relates to a fingerprint lock technical field specifically is a fingerprint lock.

Background

The existing fingerprint lock is connected with a pin through a motor push plate, and in order to keep reliable and stable transmission between the pin and the push plate, the width of the push plate is far larger than the diameter of the pin;

in addition, even if the width of the push plate is larger than the diameter of the pin, there are the following problems: 1. when the fingerprint lock is strongly vibrated, the pin and the push plate can fall off or have poor conflict, so that the unlocking of the fingerprint lock is invalid;

2. the width of the push plate is too wide, so that the push plate occupies the space inside the fingerprint lock, and the integral thickness of the fingerprint lock is increased;

3. the installation position to the motor needs higher requirement, for example, after the motor installation, the distance between pin and the push pedal is nearer, and the push pedal excessively extrudees the pin, influences the life of motor, if the distance is far away, leads to again that power transmission is inefficient between pin and the push pedal, and the fingerprint lock is unblanked easily inefficacy.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an antidetonation fingerprint lock to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a fingerprint lock comprises a clutch arranged on the fingerprint lock, a motor for providing power for the clutch and a push plate arranged on the motor; the push plate is provided with a groove, and a pin arranged on the clutch is in adaptive connection with the groove.

As the utility model discloses a preferred technical scheme: one end of the pin is in sliding fit with the clutch, and the other end of the pin is provided with a bulge; wherein the protrusion slides along the groove.

As the utility model discloses a preferred technical scheme: the protrusion with still be equipped with the annular between the pin, through the annular with the connection of recess realizes the clutch along the reliable and stable slip of recess.

As the utility model discloses a preferred technical scheme: the groove is arranged in a circular arc shape.

Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that: 1. the groove is connected with a pin arranged on the clutch in a matching way; therefore, the pin and the groove are stably connected, and the pin and the groove cannot fall off even if the pin and the groove are violently vibrated, so that the linkage of the clutch and the door handle is stable and reliable; even if the lock is unlocked by technical means, for example, by violent vibration or knocking, the door lock cannot be opened.

2. Owing to utilize the looks adaptation of pin and recess to be connected to make the width of motor push pedal obtain reducing, both reduced the occupation to fingerprint lock inner space, reduced the whole thickness of fingerprint lock again.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-2, the present invention provides an embodiment: a fingerprint lock comprises a clutch 1 arranged on the fingerprint lock, a motor 4 for providing power for the clutch 1 and a push plate 3 arranged on the motor 4; the push plate 3 is provided with a groove 2, and the pin 6 arranged on the clutch 1 is connected with the groove 2 in a matching way.

Through the technical scheme, the device changes the internal structure of the fingerprint lock, so that the device has more imaginable beneficial effects;

for example: the pin 6 on the clutch 1 is connected with the groove 2 in a matching way; thereby make pin 6 and recess 2 be connected stably, even violent vibrations can not lead to pin 6 and recess 2 to drop yet, and then make clutch 1 and door handle's linkage reliable and stable.

Owing to utilize the looks adaptation of pin 6 and recess 2 to be connected to make the width of the push pedal 3 of motor obtain reducing, both reduced the occupation to fingerprint lock inner space, reduced the whole thickness of fingerprint lock again.

The distance between the clutch 1 and the pin 6 can be accurately controlled through visual observation, so that the requirement on the installation position of the motor 4 is greatly reduced, namely, as long as one end of the pin 6 is positioned in the groove 2.

In order to further ensure that the device is reliably connected, one end of the pin 6 is in sliding fit with the clutch 1, and the other end of the pin 6 is provided with a bulge 7; wherein, protruding 7 along the recess 2 slides, is located recess 2 through protruding 7 for even push pedal 3 moves up and down, all can drive the removal of pin 6, and then makes the power transmission efficiency of motor 4 higher, more effective.

In order to further reduce the requirement on the installation position of the motor, for example, after the motor is installed, the distance between the pin and the push plate is short, the push plate excessively extrudes the pin, the service life of the motor is influenced, if the distance is long, the power transmission efficiency between the pin and the push plate is low, and the fingerprint lock is easy to lose efficacy. Protruding 7 with still be equipped with annular 5 between the pin 6, through annular 5 with the recess 2 is connected, realize clutch 1 along recess 2 reliable and stable slip.

Through annular 5 and lug 7 with recess 2's looks adaptation is connected, both can make clutch 1 be circular motion along recess 2, and pin 6 contacts with push pedal 3 all the time when making circular motion again, and then makes opening, shutting of fingerprint lock reliable, stable, especially solved current equipment because of pin 6 connects unstablely, lead to clutch 1 and door handle to be connected inefficacy, and then lead to the problem that the fingerprint lock inefficacy of unblanking.

Because the ring groove 5 is connected with the groove 2 in a matching way, the ring groove 5 is only required to be clamped on the groove 2, and then the motor 4 is positioned, so that the requirement on the installation position of the motor 4 is reduced; meanwhile, the gap between the annular groove 5 and the groove 4 can buffer the thrust of the pin 6 against the push plate 3, so that the movement of the push plate 3 is not limited, and the failure of power transmission is not caused.

Because the groove 2 is arranged in a circular arc shape, the clutch 1 can do circular motion, and the door handle can rotate conveniently.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
