Description
Technical field
The present invention relates to a kind of baroswitch, more particularly to a kind of Multifunctional, air compresses switch.
Background technology
Existing baroswitch, open in usual, normally closed type or change type are generally divided into, are disconnection shape when open in usual i.e. initial
State, conducting is closed when air pressure reaches certain value；It is closure conducting state when normally closed type is initial, when air pressure reaches certain value
Disconnect；Two normally closed interlock conductings, two normally open contacts are disconnected when change type is initial, and two are realized after air pressure reaches certain value
Individual normally closed interlock disconnects, two normally open contact closures.But at present, the baroswitch of use, it has simple function, no
Normally opened, normally closed and normally closed and normally opened conversion can be realized simultaneously, so that its use range is restricted.
The content of the invention
The purpose of the present invention：The defects of in order to overcome prior art, the invention provides a kind of Multifunctional, air to compress switch, its
Normally opened, normally closed and normally closed and normally opened conversion can be realized simultaneously, and function is extensive, and use range is wide.
Technical scheme：A kind of Multifunctional, air compresses switch, and includes shell, and described shell is provided with air inlet
Hole, described shell is interior to be provided with movable contact spring, normally opened static contact, normally closed static contact, diaphragm, jacking block, and described diaphragm arrangement is right
End position on the inside of air admission hole is answered, described jacking block is pressed on diaphragm, and described movable contact spring is linked with jacking block, in shell also
Provided with the back-moving spring for resetting jacking block, normally opened static contact, normally closed static contact are separately positioned on the both sides of movable contact spring, normally closed quiet
Contact is located at movable contact spring relative to normally opened static contact and normally opened static contact, normally closed is corresponded on diaphragm side, described movable contact spring
Static contact position is respectively equipped with normally opened moving contact, normally closed moving contact, and described normally closed static contact turns on normally closed moving contact, described
Shell on be additionally provided with the first pin turned on movable contact spring, the second pin turned on normally closed static contact and with normally opened stationary contact
3rd pin of head conducting.
Using above-mentioned technical proposal, need to realize it is normally closed with normally opened translation function when, it is only necessary to by the first pin, the
Two pins, the 3rd pin are connected with external connection respectively, and now, normally opened static contact is separated with normally opened moving contact, normally closed stationary contact
Turned between head and normally closed moving contact, when air pressure reaches certain value, diaphragm drives jacking block motion, so as to drive movable contact spring to normal
The motion of static contact direction is opened to turn on normally opened static contact, when air pressure is returned to normal value, in the presence of back-moving spring, top
Block, movable contact spring reset, and normally opened static contact is separated with normally opened moving contact, is turned between normally closed static contact and normally closed moving contact；
When needing to realize normally opened function merely, it is only necessary to which the first pin, the 3rd pin are connected with external connection；Needing simple realize
During normally closed function, it is only necessary to be connected the first pin, the second pin with external connection.Therefore, the Multifunctional, air of this structure
Compress switch, it can realize normally opened, normally closed and normally closed and normally opened conversion simultaneously, and function is extensive, and use range is wide.
The further setting of the present invention：Wedge, shell interior edge air admission hole medial extremity circumferential position are provided with described shell
Step is additionally provided with, described diaphragm is pressed on step through wedge.
Using it is above-mentioned further set, diaphragm is pressed on step by wedge so that diaphragm it is easier for installation,
It is simple in construction.
The further setting of the present invention：Described wedge is provided with pilot hole, is corresponded on described jacking block and is oriented to hole position
Guide holder is installed, guide holder is plugged in pilot hole.
Further being set using above-mentioned, jacking block can slide along pilot hole so that the slip of jacking block is more stable, from
And cause normally opened moving contact on movable contact spring, switch between normally closed moving contact and normally opened static contact, normally closed static contact it is more stable.
The present invention's is further set again：Described jacking block is provided with briquetting, described movable contact spring be pressed on briquetting with
Between jacking block.
Using above-mentioned setting further again so that movable contact spring it is easy for installation, it is simple in construction, when it is moved with jacking block more
Add stabilization.
The present invention's is further set again：Described shell is provided with the installation cavity for being used for installing back-moving spring, installation
Chamber one end is extended to outside shell, and the outboard end of installation cavity is provided with limit plug, back-moving spring be located in installation cavity and both ends respectively with
Limit plug, briquetting contradict.
Using above-mentioned setting further again so that back-moving spring it is easier for installation, jacking block can be resetted well.
The present invention's is further set again：Sealing ring is additionally provided between described diaphragm and step.
Using above-mentioned setting further again so that the good airproof performance between diaphragm and step, gas leakage will not be produced,
So that the stable work in work of switch, high sensitivity.
