Abstract
The invention discloses a change-over switch for a flameproof casing. The change-over switch comprises a switch body, wherein the switch body is provided with a control knob; the control knob is entirely recessed in the switch body; the height of the control knob is lower than that of the switch body; the surface of the control knob is provided with an adjusting socket; the side of the switch body is provided with an opening; the side of the control knob is exposed from the opening; the opening is internally provided with an elastic gasket; the elastic gasket is fitted with the ground of the control knob; the switch body is further provided with a baffle plate; the baffle plate is fitted with the elastic gasket, so as to prevent the elastic gasket from falling off; the side of the control knob is provided with an anti-skid thread; and the elastic gasket is made of butadiene rubber. According to the change-over switch for the flameproof casing provided by the invention, the control knob is entirely recessed in the switch body, and the height of the control knob is lower than that of the switch body, so that even if external forces accidentally contact with the control knob, the external forces do not directly act on the control knob, so that the occurrence of key jumping due to the external forces can be avoided and the use is safer.
Description
Technical field
The present invention relates to a kind of permutator, more precisely, be a kind of permutator for flame proof casing.
Background technology
Permutator is that a kind of two-way or two-way of being available for is with power source or the device for switching of load transfer.Permutator is formed by more piece contact combinations, in the electrical apparatus, it is used for non-frequently connecting and disjunction circuit, switches on power and load, measuring three-phase voltage and control rotating and the star delta starting etc. of low capacity asynchronous motor, it is an entirety that these parts are fastened by bolts.The permutator control handle when in use being currently used for flame proof casing is exposed outside, by the easy skip key of External Force Acting, even has an accident.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of and use the safer permutator for flame proof casing.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
A kind of permutator for flame proof casing, comprise a Switch main body, described Switch main body is provided with a control handle, described control handle entirety is depressed in Switch main body, the height of control handle is less than the height of Switch main body, the surface of control handle is provided with a regulation socket, the side of described Switch main body is provided with a gap, the side of control handle is exposed from gap, an elastomeric pad it is provided with in gap, described elastomeric pad is closely sealed with the ground of control handle, a catch it is additionally provided with on described Switch main body, described catch is fitted with elastomeric pad, prevent elastomeric pad from coming off.
As preferred embodiment of the present invention, the side of described control handle is provided with antiskid thread.
As preferred embodiment of the present invention, described elastomeric pad is made up of butadiene rubber.
The permutator for flame proof casing of the present invention, control handle entirety is depressed in Switch main body, the height of control handle is less than Switch main body, accordingly even when there is external force to be accidentally in contact with it, also control handle will not be directly acted on, avoid the situation of the skip key generation because of external force, use safer.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the permutator for flame proof casing of the present invention；
Fig. 2 is the perspective view of the permutator for flame proof casing in Fig. 1, is now another visual angle.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention are made apparent clear and definite defining.
Such as Fig. 1, shown in Fig. 2, a kind of permutator 1 for flame proof casing, comprise a Switch main body 2, described Switch main body 2 is provided with a control handle 31, described control handle 31 entirety is depressed in Switch main body 2, the height of control handle 31 is less than the height of Switch main body 2, the surface of control handle 31 is provided with a regulation socket 32, the side of described Switch main body 2 is provided with a gap 4, the side of control handle 31 is exposed from gap 4, an elastomeric pad 51 it is provided with in gap 4, described elastomeric pad 51 is closely sealed with the ground of control handle 31, a catch 52 it is additionally provided with on described Switch main body 2, described catch 52 is fitted with elastomeric pad 51, prevent elastomeric pad 51 from coming off.
As to further improvement of the present invention, the side of described control handle 31 is provided with antiskid thread.
As to further improvement of the present invention, described elastomeric pad 51 is made up of butadiene rubber.
The permutator for flame proof casing of this invention, control handle entirety is depressed in Switch main body, the height of control handle is less than Switch main body, accordingly even when there is external force to be accidentally in contact with it, also control handle will not be directly acted on, avoid the situation of the skip key generation because of external force, use safer.
The mentality of designing of the present invention is below described the most in one embodiment, and in the case of system allows, the present invention can expand to the most external more functional module, thus extends its function to greatest extent.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any change expected without creative work or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims are limited.
