Detailed Description

The utility model will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.

Referring to fig. 1-4, the present utility model provides a technical solution: a dustproof and waterproof buzzer is characterized in that one sides of two guide rods, which are opposite, are fixedly connected with limiting blocks, the limiting blocks are movably connected with the inner wall of a supporting frame, and the limiting blocks play a limiting role.

The arch support is made of silica gel materials, and plays a role in balancing force.

The both sides of manger plate sealed lid are all fixedly connected with ear piece, and the ear piece facilitates the user to carry out locking connection to this device.

The guide rods and the support frames are in one-to-one correspondence, and the guide rods play a role in guiding.

The support frame is fixedly connected with the water retaining sealing cover, the number of the support frames is a plurality of, the two support frames are designed at equal distances, and the support frames play a role in supporting and connecting.
