Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings. Detailed Implementation

[0012] like Figure 1As shown, a buzzer alarm anti-loss device includes an upper shell 1, a middle frame 2, and a lower shell 3. The upper shell 1 and the lower shell 3 are assembled as one unit through the middle frame 2. The bottom of the upper shell 1 is provided with a connecting buckle 11. The inner wall of the middle frame 2 is provided with a connecting groove 21 that is adapted to the connecting buckle 11. The connecting groove 21 passes through the top surface of the middle frame 2. The bottom surface of the middle frame 2 is provided with a buckle body 22. The lower shell 3 is provided with a buckle groove 31 that is adapted to the buckle body 22. The bottom surface of the middle frame 2 is provided with positioning grooves 23. The bottom surface of the inner cavity of the lower shell 3 is provided with a positioning block 32 that is adapted to the positioning groove 23. This device can be easily disassembled and assembled, facilitates later maintenance and repair, and greatly extends its service life.

[0013] The inner cavity of the middle frame 2 is provided with a PCBA board 24. The side wall of the PCBA board 24 is distributed with limiting grooves 25. The inner wall of the middle frame 2 is distributed with limiting blocks 26 that are adapted to the limiting grooves 25, so as to better ensure the firmness and stability of the internal space components and make the components less prone to shaking and damage.

[0014] The bottom surface of the inner cavity of the lower shell 3 is provided with a buzzer 33, the bottom surface of the PCBA board 24 is in contact with the buzzer 33, the top surface of the PCBA board 24 is provided with a spring 27, the inner cavity of the upper shell 1 is provided with a battery 12, the bottom surface of the battery 12 is in contact with the spring 27, the top of the upper shell 1 is made of elastic material and adopts an internal switch design, which greatly reduces the probability of accidental switch activation, makes more reasonable use of space, is more compact, and is easy to carry. When working, simply press the upper shell 1 to make the battery 12 squeeze inward to activate the spring 27, connect the power supply, and make the PCBA board 24 and the buzzer 33 work, which can effectively locate and remind.

[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
