Description

Technical Field

[0001] The utility model relates to the technical field of security alarms, in particular to an alarm device for residential area security. Background Art

[0002] Security equipment is widely used in various fields. In schools, communities, banks, warehouses, etc., the installation of security monitoring equipment can timely and effectively avoid property losses and improve personal safety prevention and control. Security gates can often be seen in communities. On the one hand, they can prevent the entry of outsiders, and on the other hand, they can effectively manage residents.

[0003] A Chinese patent discloses a two-pole switch device for a residential entrance guard (publication number: CN 214116383U), which belongs to the technical field of entrance guard equipment. The two-pole switch device for a residential entrance guard comprises a support, a left support rod is fixedly connected to the top of the support, a fixed block is fixedly connected to the inner side wall of the left support rod, a rotating rod is installed inside the fixed block, the rotating rod passes through the fixed block and is rotatably connected thereto, a door frame is fixedly connected to the side wall of the rotating rod, the bottom end of the rotating rod is rotatably connected to the support, a lower mounting frame is fixedly connected to the outer wall of the left support rod, an upper mounting frame is fixedly connected to the top of the lower mounting frame, and a connecting ring is fixedly connected to the top of the rotating rod. The door guard can be closed at a relatively slow speed to avoid hitting passers-by due to too fast closing. When a person passing through is detected, the door guard can be opened at a relatively fast speed to reduce the waiting time of passers-by.

[0004] The above patent reduces waiting time and the probability of colliding with pedestrians by opening quickly and closing slowly. Such community access control security doors are relatively high and are not equipped with alarm devices. Especially at night, if no alarm device is installed, it is difficult to prevent outsiders from climbing the door frame to enter the community, thus creating a safety hazard. Therefore, there is room for improvement. Utility Model Content

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1-3 In the present embodiment, an alarm device for community security comprises a security door 1, a mounting plate 2 and an alarm device 3. The mounting plate 2 is fixedly connected to the top of the security door 1. The mounting plate 2 is an inverted U-shape, and a plurality of mounting holes 21 are symmetrically and equidistantly provided in the two downward side surfaces. A card slot 22 is provided at the top of the mounting plate 2. A threaded hole 11 matching the mounting hole 21 in the mounting plate 2 is provided at the top of the security door 1. The alarm device 3 is arranged at the top of the mounting plate 2. The alarm device 3 is composed of a pressing plate 31, an alarm switch 32, an alarm 33 and a spring telescopic rod 34. The spring telescopic rod 34 is in a plurality of numbers, and its bottom is equidistantly fixed to the top of the mounting plate 2, and the telescopic end is fixed to the pressing plate 31. The alarm switch 32 is connected to the alarm 33.

[0020] Through the above technical solution: the alarm device 3 is arranged on the top of the security door 1 through the mounting plate 2. When the pressing plate 31 in the alarm device 3 is squeezed by external force, it will move downward, so that the inner surface of the pressing plate 31 is pressed onto the alarm switch 32. The alarm 33 is turned on by the alarm switch 32. The alarm 33 sends out an alarm to warn the person who climbs over, and at the same time reminds the security personnel to check the gate of the community, so as to prevent outsiders from entering the community by climbing over the security door and causing safety hazards.

[0021] Preferably, the alarm switch 32 in the alarm device 3 is arranged inside the top of the mounting plate 2, and an alarm switch 32 is provided between every two spring telescopic rods 34. There are two alarms 33, which are symmetrically arranged on both sides of the top of the mounting plate 2. The pressing plate 31 is movably connected to the top of the mounting plate 2 through the card slot 22.

[0022] Through the above technical scheme: the pressing plate 31 is clamped in the slot at the top of the mounting plate 2 to limit the moving direction of the pressing plate 31. The pressing plate 31 can be lifted up by the spring telescopic rod 34 to make it elastic. Under normal conditions, the pressing plate 31 will not move downward to prevent it from touching the alarm switch 32. At the same time, it also prevents the pressing plate 31 from being pressed downward due to high pressure and causing damage to the alarm switch 32 and the alarm 33. By setting up multiple alarm switches 33, when any position of the pressing plate 31 is pressed downward due to pressure, the alarm switch 32 can be pressed, thereby driving the alarm 33 to sound an alarm to prevent outsiders from climbing over. The pressing plate 31 can also play a role in rain and dust protection, and protect the alarm switch 32 and the alarm 33.

[0023] Preferably, the slot 22 is provided with a plurality of through holes 23 equidistantly connected to the outside and slanting downward.

[0024] Through the above technical solution: the through hole 23 is convenient for draining the water entering the card slot 22, so as to ensure the stability of the operation of the equipment, and at the same time, the alarm sound emitted by the alarm 33 can be quickly transmitted through the through hole 23.

[0025] Preferably, the mounting plate 2 is buckled on the top of the security door 1 and is fixedly connected to the security door 1 through the cooperation of the mounting holes 21, the threaded holes 11 and the bolts.

[0026] Through the over-rising technical solution: the mounting plate 2 is convenient for loading and unloading the mounting plate 2 on the security door 1 by means of the bolts inserted through the mounting holes 21 and the threaded holes 11, thereby facilitating the loading and unloading of the mounting plate 2 on the security door 1, thereby facilitating the loading and unloading of the alarm device 3 connected to the mounting plate 2 on the security door 1.

[0027] The embodiment is implemented as follows:

[0028] When the present application is in use, the alarm device 3 is connected to the top of the security door 1 through the mounting plate 2, and the mounting plate 2 and the security door 1 are detachably fixedly connected by bolts 4. When an outsider climbs over the security door 1, it is necessary to borrow force from the top of the security door 1, so that the pressing plate 31 in the alarm device 3 moves downward in the slot 22 at the top of the mounting plate 2, thereby touching the alarm switch 32. The alarm switch 32 turns on the siren 33 and sounds an alarm to drive away and warn the climbers, and at the same time remind the security personnel to check the community, thereby effectively preventing outsiders from climbing over the security door and entering the community, reducing safety hazards.

[0029] In addition, it can also be directly used to transform the security door 1 of old residential areas. It only needs to make a threaded hole 11 corresponding to the position of the mounting hole 21 in the mounting plate 2 on the top of the security door 1, and the alarm device 3 can be installed on the top of the security door 1 through the cooperation of the bolt 4 and the mounting plate 2 to play a security role.

[0030] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; the technology not described in detail in the present invention is implemented with the existing technology.
