Abstract
A buzzer protective cover comprises a casing, and a cavity for accommodating a buzzer is arranged inside the casing. The protective cover is characterized in that the lower part of the casing is opened; a top cover is arranged at the upper part of the casing; an opening is formed on the wall of the casing and is adjacent to the top cover; the opening is inclined relative to the top cover at an angle of no larger than zero degree. The utility model is easy to detach and install. The buzzer can make a sound that lasts a long time and spreads extensively. Moreover, the utility model is dust-proof and water-proof.
Description
Technical field
The utility model relates to industrial circle, specifically is a kind ofly to be convenient to install and the hummer protective cover of Waterproof, moistureproof and dustproof.
Background technology
Common hummer is to expose outside mostly in the prior art, housing without any protective cover, even it also is fairly simple protection and not quick detachable and installation that the protective cover housing is arranged, the time of the hummer sound continuity of sending is short like this, spread scope is also restricted, and does not have the dust and water protection effect.
Summary of the invention
The problems referred to above of depositing in order to solve in the prior art and weak point design a hummer protective cover, and concrete technical scheme is as follows:
A kind of hummer protective cover comprises housing, is provided with the cavity of settling hummer in housing.The lower housing portion of described protective cover is opened wide, and the top of housing is provided with top cover, is provided with opening on housing wall, near the top cover place, and opening direction and top cover angulation are not more than 0 and spend, and opening communicates with cavity.Housing is cylindrical.
The outer lower edge of described housing is provided with the short cylinder projection that a plurality of height differ.Lower edge in the described housing is provided with a plurality of point of fixity buttons.Described point of fixity is buckled with 8, and wherein 2 is anti-" II " shape, and 6 is anti-" 7 " font, and 2 is that to be separated by 3 between anti-" II " shape point of fixity button be anti-" 7 " font point of fixity button.
The top of described cavity is provided with circular groove, and this circular groove communicates with described opening by the arc square hole.Described circular groove bottom surface is provided with rubber ring.Described opening is a bugle shape, and described arc square hole has four.
Be provided with the double-screw bolt perpendicular to top cover on the circular groove limit on cavity top, the height of double-screw bolt is corresponding with the thickness sum of the used PCB of hummer with the thickness of hummer.Described double-screw bolt has two.
Little short column effect increases friction to be made more in backing out housing, also can reach effect attractive in appearance in addition.Instead " 7 " shape and " II " form point button, it is convenient to loading and unloading.Double-screw bolt is used for fixing the pcb board and the hummer of soft copy.Circular groove is used to place hummer.Circular groove by the arc square hole with the design effect that described opening communicates is, sound sends by four arc square openings from hummer and spreads out of, around reaching by diffusion in four bugle shape opening sound set then, make the scope of sound transmission wide, the time of continuity is long.This protective cover need cooperate tower warning lamp to use, and the warning lamp top also is provided with point of fixity and buckles the bayonet socket that matches.
