Description
Technical field
The utility model is related to a kind of protective cover, more particularly, to a kind of protective cover of pressure switch.
Background technology
At present, pressure cooker has become one of widely known cooking tools.Pressure cooker is in use with air pressure
Rising, cause pot to deform, now pressure switch promote installed in the bottom of a pan push rod so that contact disconnect, stop heating, treat
After pot is recovered as former state, heating is started again at, so circulation.Pressure switch of the prior art does not have protection device, contact
It is exposed easily to be contacted with the pernicious gas in air outside, the oxidation of contact is caused, cause poor contact of contacts, ultimately result in
Contact no power, have impact on the use of pressure cooker.Therefore, a kind of protection device of pressure switch is researched and developed, while protection contact
Do not influence the use of pressure switch again, be the technical problem that this area is badly in need of solving.Thus the utility model produces.
Utility model content
For the above-mentioned technical problem of prior art, the purpose of this utility model is to provide a kind of protection of pressure switch
Cover, it is set up outside pressure switch, effectively protects contact, it is to avoid oxygen caused by the pernicious gas in contact air
Change, and do not influence the work of pressure switch.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of protective cover of pressure switch, including protection cover body, described protection cover body are provided with cavity volume, the cavity volume
Top be provided with support banking stop, the support banking stop forms support mounting groove, the sidepiece of the protection cover body with cavity volume
Several lug plate banking stops are provided with, several lug plate banking stops are arranged on the side wall of protection cover body side by side.
Described support banking stop is provided with salient point.
The beneficial effects of the utility model are as follows：
The protective cover of the utility model pressure switch, sets up in the outside of pressure switch component, and by support banking stop,
Be limited to pressure switch component in protective cover by lug plate banking stop etc., effectively protects contact, it is to avoid in contact air
Aoxidized caused by pernicious gas, and do not influence the work of pressure switch, so as to extend the protection life-span of pressure switch；The opposing party
Face, the utility model when mounted, mount support and the utility model is riveted together, and only needs a screw just to realize
Integral type is installed, easy for installation and with low cost.
