Embodiment
Incorporated by reference to shown in Fig. 1 to Fig. 8: a kind of water-tight device of the buzzer on control cabinet provided in this embodiment, packet
Include housing 1, mounting base 2 and water fender 3, the tail portion of housing 1 and the stem of mounting base 2 be connected by screw thread (in the present embodiment,
It is to be equipped with internal screw thread 11 in the tail portion of housing 1, is equipped with outer spiral shell compatible with the internal screw thread 11 in the stem of the mounting base 2
Line 21 is connected by internal screw thread 11 with the cooperation of external screw thread 21 realization between housing 1 and mounting base 2；Preferably, exist
The junction of housing 1 and mounting base 2 is equipped with gasket (not shown), can prevent water by the junction of housing and mounting base into
Enter, be further ensured that waterproof sealing effect)；The water fender 3 is located in the cavity of housing 1 and is connected with the internal chamber wall of housing 1
Connect (it in the present embodiment, is connected using buckle structure between the two, specifically: it is equipped at intervals at the edge of water fender 3 multiple
Engaging lug 31 (shows 3, but is not limited to 3) in figure, be equipped with the convex block 32 of convex in the lower part of the engaging lug 31,
The internal chamber wall of housing 1 is equipped with mounting groove 12 compatible with the engaging lug 31, opens up on the inner wall of the mounting groove 12
There is card slot 13 compatible with the convex block 32, by making convex block 32 and the clamping of card slot 13 that engaging lug 31 be made to be fixed on mounting groove
In 12, to realize the connection of the internal chamber wall of water fender 3 and housing 1, the mounting groove 12 is fixed on internal chamber wall by housing 1
Two pillars 121 constituted, spacing block set 122, the spacing block set 122 are fixedly provided on the internal chamber wall in mounting groove 12
Bottom end be in contact with the upper surface of engaging lug 31, to play the position-limiting action to water fender 3), in the stem of the housing 1
Equipped with several large through-holes 14, several small through hole 33 are equipped on the water fender 3, the large through-hole 14 and small through hole 33 are wrong
Position setting does not constitute directly connection (in combination with being learnt shown in Fig. 3 and Fig. 4)；Also, it is equipped with water outlet 15 in the side of housing 1,
The lower surface of the water outlet 15 and the upper surface of water fender 3 are in same level.

The tail end 23 of seat 2 is fixedly connected with the panel 4 of control cabinet, and installation direction of the mounting base 2 on the panel of control cabinet need to make cover
The water outlet 15 of shell-side is opening down.
Since water-tight device described in the utility model is on the panel 4 for be vertically mounted on control cabinet, the stem of housing 1 is
Positioned at the front of the panel of control cabinet, therefore, when on the panel of water injection to control cabinet, only has a small amount of droplet and pass through housing
The large through-hole 14 of 1 stem enters in the cavity of housing 1；Again since water fender 3 is blocked in the front of mounting base, and it is arranged in cover
Several large through-holes 14 of 1 stem of shell are not constituted with several small through hole 33 being arranged on water fender 3 and are directly connected to, Yi Jishe
It is in same level in the lower surface of water outlet 15 of 1 side of housing and the upper surface of water fender 3, in turn, the water of entrance
Pearl, which is difficult to enter into mounting base 2 under the blocking of water fender 3, removes damage buzzer, also, the water stopped by water fender 3 is certainly
The outflow of water outlet 15 can be converged under body gravity automatically；In addition, alarm song is transferred to by air when buzzer work
Water fender 3 is transferred in the cavity of housing 1 by the small through hole 33 being located on water fender 3, and then by being located at the big of 1 stem of housing
Through-hole 14 is penetrated into outside, plays the decibel demand of alarm.
Especially, when the water fender 3 divides for great circle arc portion 34 and roundlet arc portion 35, the great circle arc portion 34 and housing
Between the upper lateral part 18 of the internal chamber wall of the formation of following side 17 close-fitting relationship of internal chamber wall, the roundlet arc portion 35 and housing is formed
Gap matching relationship both can effectively avoid droplet when the engaging lug 31 is arranged at intervals on the edge of roundlet arc portion 35 of water fender 3
It enters in mounting base 2, ensures that alarm song can be transferred out quickly, so that waterproof effect and warning effect reach most
It is good.
Preferably, multiple finger groove portions 16 are equipped in the side of housing 1, are conducive to finger grip in this way and are referring to groove portion
16 pairs of housings 1 carry out dismounting force operation.
Preferably, one or more (2 are shown in figure) is equipped with for putting sealing in the tail end of mounting base 2
The groove 24 of pad can further avoid droplet and be entered in buzzer by the junction of mounting base 2 and the panel of control cabinet.
Preferably, the housing 1, mounting base 2 and water fender 3 be all made of transparent polymer material (such as: PC,
PVC) molding obtains, not only beautiful in this way, but also manufacturing process is simple, and mounting base 2 can be fixed on control cabinet by viscose glue
Panel on, realize seamless connection, can be further ensured that waterproof effect.
Visible in summary: water-tight device described in the utility model effective waterproof and can influence the sounding point of alarming
The requirement of shellfish, the buzzer that also can avoid being mounted on outside the panel of control cabinet are damaged by collision, and also have that structure is simple, tears open
The advantages that dress is convenient and beautiful, is conducive to control cabinet and meets IP55 high waterproofing grade requirement, has obvious progressive and industry real
With value.
It is last it is necessarily pointed out that: the foregoing is merely the preferable specific embodiments of the utility model, but this
The protection scope of utility model is not limited thereto, and anyone skilled in the art discloses in the utility model
In technical scope, any changes or substitutions that can be easily thought of, should be covered within the scope of the utility model.
