Technical Field
[0001] The utility model relates to the technical field of buzzers, in particular to a dust-proof and waterproof buzzer. Background Technique
[0002] A buzzer is an electronic device that can emit a buzzing sound. It generates vibrations through a piezoelectric sheet or electromagnetic coil inside, and then drives the air to vibrate to produce sound. Buzzers are widely used as sound-emitting devices in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic devices, telephones, and timers.
[0003] Currently, most buzzers are installed outdoors. The rain and snow weather outdoors can easily cause the buzzer to get water in, which will affect its normal use. Moreover, there is a lot of dust in the outdoor air. If the dust accumulates on the surface of the buzzer for a long time, it may cause the sound of the buzzer to become weak or distorted. Therefore, a dust-proof and waterproof buzzer is proposed to solve the above-mentioned problems. Content of the Utility Model

[0010] The installation of the first connecting rods can connect the connecting plate and the waterproof housing into a whole, and the connecting groove provides an installation space for the connecting plate.
[0011] Preferably, there are two second installation grooves, which are symmetrically distributed on the opposite sides of the two connecting grooves. The connecting grooves are communicated with the second installation grooves, and clamping grooves adapted to the wedge blocks are formed on the opposite sides of the two connecting plates.
[0012] Connecting the second installation groove with the connecting groove can facilitate the movement of the structure in the second installation groove into the connecting groove later. When the wedge block is engaged with the clamping groove, the position of the connecting plate can be fixed, and then the position of the waterproof housing can be fixed.
[0013] Preferably, clamping grooves are formed on the opposite sides of the two connecting plates. The size of the clamping grooves is adapted to the wedge blocks, and the bottom of the connecting plate is inclined and adapted to the inclined surface of the wedge blocks.
[0014] Since the inclined surface of the bottom of the connecting plate is adapted to the inclined surface of the wedge block, when the connecting plate moves downward, the wedge block can be pushed to move away from the connecting plate.
[0015] Preferably, the rectangular through holes are formed on the front and rear side walls of the waterproof housing, and the dust-proof plate is located inside the waterproof plate.
[0016] Preferably, a moving groove adapted to the moving track of the waterproof plate is formed inside the waterproof housing, and a second connecting rod is fixedly connected between the waterproof plate and the pulling plate.
[0017] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:
[0018] First, the utility model inserts the connecting plate into the connecting groove at the top of the base. At this time, the bottom surface of the second sealing ring just fits tightly with the top surface of the first sealing ring, preventing water droplets from flowing into the first installation groove and playing a preliminary waterproof role for the buzzer body. When the connecting plate moves downward to push the wedge block, driven by the sliding plate, the two wedge blocks move away from each other and compress the spring. When the connecting plate moves below the wedge block, under the elastic force of the spring, the wedge block is pushed into the clamping groove on the connecting plate, and the waterproof housing can be fixed, further playing a waterproof role for the buzzer body.
[0019] Second, the dust-proof plate inside the waterproof shell of the present utility model plays a dust-proof role for the buzzer body. When the buzzer body is not in use, the waterproof plate can prevent rainwater from entering the waterproof shell. When the buzzer body is in use, the pull plate is pulled upward. Driven by the second connecting rod, the waterproof plate moves upward into the moving groove, making the rectangular through hole unsealed, and thus not affecting the volume of the buzzer body.
