Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Example 1:

101. The embodiment of the utility model provides an anti-theft alarm device, which includes a housing 1, the housing 1 is U-shaped, and the housing 1 includes a power module 2, a sensing module 3, a control module 4, a first Switch 5 and alarm module 6.

The housing 1 is U-shaped, which is convenient for clamping and is more stable when placed in the sound pack. The various modules inside the casing 1 are physically connected.

102. The power module 2 is used to supply power to the anti-theft alarm device.

The power supply module 2 provides electricity for each module inside the casing 1, so that each module can work normally.

103. The sensing module 3 is embedded on the surface of the housing 1 to sense changes in the external environment. When the external environment remains unchanged, the sensing module 3 sends a shutdown command to the control module 4. When the external environment changes, The sensing module 3 sends an opening command to the control module 4 .

The sensing module 3 is embedded in the surface of the housing 1. Preferably, the sensing module 3 is located inside the U-shaped opening of the housing 1, so as to sense changes in the external environment in a timely and sensitive manner. When the external environment remains unchanged, the sensing module 3 The module 3 sends a closing command to the control module 4, and when the external environment changes, the sensing module 3 sends an opening command to the control module 4.
