To achieve these goals, the utility model provides a kind of switch under water, comprises knob and rotary switch, also comprises the watertight mounting base that has the switch fixed head; Wherein, described rotary switch is installed on the described watertight mounting base by the switch fixed head, and described knob passes described watertight mounting base and is connected on the described rotary switch.

In the technique scheme, the inside of described knob is equipped with light-emitting diode, the circuit communication of described Light-Emitting Diode and described electrical equipment that switch is installed under water.

In the technique scheme, described knob adopts transparent solid material to make.

In the technique scheme, have two sealing rubber rings that are used to keep watertightness on the described watertight mounting base.

In the technique scheme, the bottom of described watertight mounting base is the cylinder of a hollow, and its top then is the square that has chamfering, described foursquare four jiaos porose, utilize screw to pass these holes and realize fixing to described watertight mounting base.

In the technique scheme, described watertight mounting base adopts stainless steel material to make.

Advantage of the present utility model is:

1, switch under water of the present utility model has adopted the watertight mounting base, makes switch have good watertightness, is suitable for using under deepwater environment.

2, switch under water of the present utility model has been installed the switch indicator light, makes that switch can be luminous under water, helps diver's underwater operation.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described.

In the development process of fixed sonar, the acoustic responder that needs a kind of diver of development to use, because the employed acoustic transducer of acoustic responder requires it to be preferably in entry and opens switch later on again, this just needs a kind of appliance switch that can operate under water.In the present embodiment, be example with the appliance switch that is used for acoustic responder, switch under water of the present utility model is described.

In general, appliance switch can be divided into knob, push type or dial type according to type, because underwater environment has hydraulic pressure and increases with the depth of water, in order to guarantee the watertightness performance of switch, switch under water of the present utility model adopts knob switch.As shown in Figure 1, switch is made up of three parts under water, comprising: knob 1, watertight mounting base 5 and rotary switch 10 wherein, have the switch fixed head 9 that is used to install rotary switch 10 on the watertight mounting base 5.Choose mounting panel on the watertight electronic compartment of acoustic responder, in the select location punching of mounting panel watertight mounting base 5 is installed, knob 1 passes watertight mounting base 5 and is installed on the rotary switch 10, and rotary switch 10 is connected with the interlock circuit of acoustic responder.Below with reference to Fig. 2, the structure of various piece and mutual annexation are specifically described.

The effect of rotary switch 10 is break-makes of control acoustic responder circuit, and rotary switch 10 is installed on the switch fixed head 9, and is fixed on the inner splint 12 that is connected with watertight mounting base 5 by two copper posts 6.The top middle portion of rotary switch 10 is the projectioies of " yi word pattern ", and its bottom then is connected with the circuit of acoustic responder.Also draw two electric wire A1, B1 that are connected with the circuit of acoustic responder from the bottom of rotary switch 10.The rotary switch 10 that is adopted in the utility model is similar with rotary switch commonly used, can directly buy corresponding rotary switch from the market, as the LAS1-A type rotary switch of ONPOW company.

In order to guarantee the watertightness of switch under water, in the outside of rotary switch 10 watertight mounting base 5 is installed, have switch fixed head 9 on the watertight mounting base 5.The bottom of watertight mounting base 5 is cylinders of a hollow, its top then is the square that has chamfering, foursquare four jiaos porose, utilizing screw to pass these holes can be fixed on watertight mounting base 5 on the mounting panel of transponder watertight compartment, at the sealing rubber ring that twice O type axially and is radially arranged 14,15 of watertight mounting base to keep the watertightness of watertight mounting base 5.The switch fixed head 9 that rotary switch 10 is installed is fixed on the inner splint 12 by copper post 6, is fixed on the watertight mounting base 5 by trip bolt 13 again, and the watertight mounting base can be processed by stainless steel material.

Knob 1 is for having the knob of light indication, the top of knob 1 becomes " yi word pattern " to be rotated operation to make things convenient for the diver, its center has a cylindricality slotted hole, in the cylindricality slotted hole, light-emitting diode 3 can be installed, light-emitting diode 3 is connected to switch and turns round on the nail 2, turn round nail at switch and have two apertures on 2, two pins of light-emitting diode 3 are drawn by the aperture that switch is turned round on the nail 2 respectively, and are connected with electric wire A1, B1.In the lower end of knob 1 two axial O type rubber rings 4 are arranged successively, to guarantee the watertightness performance of switch under water.Near the part of bottom circlip for shaft 11 is installed also at knob 1, there is the recessed of " yi word pattern " bottom of knob 1.Knob 1 itself is made by hard, material transparent, in the present embodiment, can adopt polymethyl methacrylate, in other embodiments, also can adopt other to have the transparent material of high mechanical properties, corrosion-resistant, good insulating.

During switch under water by above-mentioned component-assembled present embodiment, knob 1 passed watertight mounting base 5 after, be fixed on the watertight mounting base 5 by circlip for shaft 11.After rotary switch 10 is installed on the switch fixed head 9, utilize copper post 6, screw 7 and spring shim 8 that rotary switch 10 is fixedlyed connected with the inner splint 12 on being installed in watertight mounting base 5.In connection procedure, should make " yi word pattern " projection on recessed and rotary switch 10 tops of " yi word pattern " of knob 1 bottom match.

After the assembling of switch under water of the present utility model is finished, diver's turning knob 1, the switch of fetching boiling water down makes electric equipment in running order, connects the light-emitting diode 3 in the knob 1 simultaneously, and the diver can know clearly the operating state of equipment in view of the above.
