Embodiment
Shown in Fig. 1 to Fig. 8：A kind of water-tight device for buzzer on switch board provided in this embodiment, packet
Include case 1, mounting base 2 and water fender 3, the tail portion of case 1 and the stem of mounting base 2 be connected by screw thread (in the present embodiment,
It is to be equipped with internal thread 11 in the tail portion of case 1, outer spiral shell compatible with the internal thread 11 is equipped in the stem of the mounting base 2
Line 21 is connected by internal thread 11 with the cooperation of external screw thread 21 realization between case 1 and mounting base 2；Preferably, exist
The junction of case 1 and mounting base 2 is equipped with gasket (not shown), can prevent water by the junction of case and mounting base into
Enter, be further ensured that waterproof sealing effect)；The water fender 3 is located in the cavity of case 1 and is connected with the internal chamber wall of case 1
Connect (is to be connected using buckle structure between the two, specially in the present embodiment：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, the convex block 32 of convex is equipped in the lower part of the engaging lug 31,
The internal chamber wall of case 1 is equipped with mounting groove 12 compatible with the engaging lug 31, is opened 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 water fender 3 and case 1 internal chamber wall connection, the mounting groove 12 is fixed on internal chamber wall by case 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 case 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 is wrong with small through hole 33
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 case 1,
The lower surface of the water outlet 15 is in the upper surface of water fender 3 in same level.
It please refers to shown in Fig. 9：The pars stridulans (not shown) of buzzer is threaded through in the cavity 22 of mounting base 2, installation
The tail end 23 of seat 2 is fixedly connected with the panel 4 of switch board, and installation direction of the mounting base 2 on the panel of switch board need to make cover
The water outlet 15 of shell-side is opening down.
Since water-tight device of the present invention is vertically mounted on the panel 4 of switch board, the stem of case 1 is to be located at
Therefore the front of the panel of switch board when on the panel of water injection to switch board, it is first by case 1 only to have a small amount of droplet
The large through-hole 14 in portion enters in the cavity of case 1；Again since water fender 3 is blocked in the front of mounting base, and it is arranged in case 1
Several large through-holes 14 of stem are not constituted with several small through hole 33 being arranged on water fender 3 and are directly connected to, and are located at
The lower surface of the water outlet 15 of 1 side of case is in the upper surface of water fender 3 in same level, in turn, the droplet of entrance
It is difficult to enter under the blocking of water fender 3 in mounting base 2 and removes damage buzzer, also, the water stopped by water fender 3 is at itself
The outflow of water outlet 15 can be converged under gravity automatically；In addition, when buzzer works, alarm song is transferred to gear by air
Water plate 3 is transferred to by the small through hole 33 being located on water fender 3 in the cavity of case 1, and then by being located at the big logical of 1 stem of case
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 case
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 case 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 case 1, are conducive to finger grip in this way and are referring to groove portion
16 pairs of cases 1 carry out dismounting force operation.
Preferably, one or more (showing 2 in figure) is equipped in the tail end of mounting base 2 to seal for putting
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 switch board.
Preferably, the case 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 switch board by viscose glue
Panel on, realize be seamlessly connected, can be further ensured that waterproof effect.
It is visible in summary：Water-tight device of the present invention effective waterproof and can influence the sounding decibel of alarming
It is required that the buzzer that also can avoid outside the panel of switch board is damaged by collision, and also there is simple in structure, dismounting side
Just with beauty the advantages that is conducive to switch board and meets IP55 high waterproofing grade requirements, has apparent progressive and the practical valence of industry
Value.
It is last it is necessarily pointed out that：The foregoing is merely the preferable specific implementation mode of the present invention, but the present invention
Protection domain be not limited thereto, any one skilled in the art in the technical scope disclosed by the present invention,
The change or replacement that can be readily occurred in, should be covered by the protection scope of the present invention.
