Description

An alarm keyhole cover

technical field

The utility model relates to the technical field of intelligent doors, in particular to an alarm escutcheon.

Background technique

As a tool to protect the safety of each family's property, door locks have become a must for every family. There are many types of door locks, and the requirements for door locks are different in various occasions. Now ordinary families generally use anti-theft door locks, which are safe and affordable. It is relatively cheap. With the continuous development of technology, smart door locks have emerged as the times require. They usually have two modes: palmprint or fingerprint unlocking and unlocking through the keyhole. Even if the palmprint or fingerprint fails to unlock, you can also unlock through the traditional lockhole The unlocking mode is simple and convenient to unlock; this structural setting also provides opportunities for many criminals, who often open the smart door by breaking the lock hole, and then steal, causing losses to people's property.

Utility model content

Based on this, the utility model provides an alarm escutcheon.

An alarm escutcheon, comprising a bracket, a screw post, a circuit board, a lock cover, and a terminal block, one end of the screw post is fixedly mounted on the support, the circuit board is fixedly mounted on the screw post, and the The lock cover is fixedly mounted on the other end of the screw post, and the circuit board includes at least one set of switches with elastic structures, one end of the switch is fixedly mounted on the circuit board, and the other end is fixedly mounted on the circuit board. The lock cover is pressed tightly between the lock cover and the circuit board, and the connecting terminal is fixedly installed on the circuit board for connecting the alarm device.

One of the embodiments is that the switches are in three groups, and the finished fonts are installed on the circuit board.

One of the embodiments is that the circuit board is in interference connection with the screw post.

The above-mentioned alarm escutcheon is set through the cooperation of the circuit board, the switch and the lock cover. The lock cover presses the switch on the circuit board. The alarm device connected to the terminal sends out an alarm signal, so that people know that the door lock is broken, and they can call the police immediately, so that criminals dare not continue their illegal activities, effectively preventing the theft of property at home and ensuring the safety of people's property.

Description of drawings

Fig. 1 is a structural schematic diagram of an alarm escutcheon according to an embodiment of the present invention.

As shown in the drawings: bracket 10, screw post 20, circuit board 30, switch 31, lock cover 40.

Detailed ways

In order to make the above purpose, features and advantages of the present utility model more obvious and understandable, the specific implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a full understanding of the present invention. However, the utility model can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below limit.

It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used herein in the description of the utility model is only for the purpose of describing specific implementations, and is not intended to limit the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in Figure 1, an alarm escutcheon includes a bracket 10, a screw column 20, a circuit board 30, a lock cover 40, and a terminal block, one end of the screw column 20 is fixedly mounted on the bracket 10, and the The circuit board 30 is fixedly installed on the screw column 20, the lock cover 40 is fixedly installed on the other end of the screw column 20, and the circuit board 30 includes at least one set of switches 31 with an elastic structure. One end of the switch 31 is fixedly installed on the circuit board 30, the other end is fixedly installed on the lock cover 40 and pressed between the lock cover 40 and the circuit board 30, and the connecting terminal is fixedly installed on the circuit board 40, for connecting the alarm device.

When criminals destroyed the lock cover 40, the switch 31 popped up to make the circuit board 30 in a conduction state, and the electric current made the alarm device open by the connection terminal, and the alarm device began to send an alarm signal to remind people that the door lock was destroyed.

Like this, a kind of alarm escutcheon, through the cooperating arrangement of circuit board 30, switch 31 and lock cover 40, lock cover 40 presses switch 31 on circuit board 30, after lock cover 40 is destroyed, switch 31 pops up , so that the circuit board 30 is turned on, and the alarm device connected through the terminal sends out an alarm signal, so that people know that the door lock is damaged, and they can immediately call the police, so that criminals dare not continue their illegal activities, effectively preventing the property from being stolen at home. The safety of people's property is guaranteed.

Furthermore, in order to achieve a better anti-theft effect, the switches 31 are in three groups, and the finished fonts are installed on the circuit board 30 .

In this way, when the lock cover 40 is pried a little, the switch 31 pops up, the circuit board 30 is turned on, and the alarm device sends an alarm signal. It is not necessary to wait until the lock cover 40 is completely destroyed before starting to report to the police, which makes the whole device more responsive. Sensitive, fast, better anti-theft effect.

Further, in order to better install the circuit board 30 , the circuit board 30 is in an interference connection with the screw post.

In this way, the circuit board 30 and the screw post 20 are in interference connection, so that the installation of the circuit board 30 is more stable, and at the same time, there is no other auxiliary process for installation, which is simpler and more convenient.

The various technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the various technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.

The above-mentioned embodiments only express several implementation modes of the utility model, and the description thereof is relatively specific and detailed, but it should not be understood as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
