Description
Technical field
The utility model relates to a kind of switch, particularly a kind of jettron of regulating Compress Spring.
Background technology
The sensitive switch design of jettron makes switch have in high electric current, the single-pole double throw way of contact and switch dead band characteristics such as (the poor or hysteresis of machinery).Design and the low cost of dwindling profile make this switch become desirable OEM product.
At present, the end cap that the jettron that occurs on market and the data mainly fastens by pedestal, with pedestal, be provided with working chamber between end cap and the pedestal, pedestal is provided with the air inlet with the working chamber conducting, the top of working chamber is provided with can be along the diaphragm of working chamber axial reciprocating slippage, and diaphragm is provided with conducting strip towards the end face of working chamber bottom, and the bottom of working chamber is provided with and extends to the outer pin of working chamber, the below that pedestal is positioned at working chamber is provided with spring base, is provided with Compress Spring between spring base and the diaphragm.The distance of spring-compressed has determined the time of switch open, at some special occasions, jettron needs quick or slows down unlatching, traditional jettron can only be realized this function by the spring force of regulating Compress Spring, yet Compress Spring is after process is used for a long time, its spring force is difficult to control, can't reach the quick of expection or slow down unlatching.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of jettron of simple in structure, the Compress Spring regulated that stability is high.
For achieving the above object, the utility model provides following technical scheme: a kind of jettron of regulating Compress Spring, include pedestal, end cap with the pedestal fastening, be provided with working chamber between end cap and the pedestal, pedestal is provided with the air inlet with the working chamber conducting, the top of working chamber is provided with can be along the conducting strip of working chamber axial reciprocating slippage, the bottom of working chamber is provided with and extends to the outer pin of working chamber, the below that pedestal is positioned at working chamber is provided with spring base, be provided with Compress Spring between spring base and the conducting strip, and conducting strip is connected by securing member with an axial end of Compress Spring, it is characterized in that: described pedestal is provided with the spring base placed cavity, spring base is positioned in the spring base placed cavity and can be along the slippage of spring base placed cavity axial reciprocating, and spring base is with respect to being provided with and extending to the outer spring base regulating part of pedestal with the conflict other end place of an end of Compress Spring.
Wherein, the spring base regulating part includes the adjusting screw(rod) that is threaded engagement with spring base.
Adopt technique scheme, by extend to the spring base regulating part outside it pedestal setting, the interior position of spring base placed cavity that makes spring base be in pedestal can change by sounding along with the adjusting of spring base regulating part, be that the axial location that spring base is in the spring base placed cavity can change, make the compression distance of Compress Spring adjusted, thereby make the opening speed of jettron controlled.
The utility model further is set to: the pressure section that spring base includes the location division and is connected with the location division, and its location division is arcuation, and pressure section is discoid body.
Adopt technique scheme, setting makes the conflict between spring base and the Compress Spring more compact like this, can effectively place Compress Spring and in use occur to swing or skew.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
Such as Fig. 1, a kind of jettron of regulating Compress Spring shown in Figure 2, include pedestal 1, end cap 2 with pedestal 1 fastening, be provided with working chamber 3 between end cap 2 and the pedestal 1, pedestal 1 is provided with the air inlet 11 with working chamber 3 conductings, the top of working chamber 3 is provided with can be along the conducting strip 5 of working chamber 3 axial reciprocating slippages, the bottom of working chamber 3 is provided with the pin 6 that extends to outside the working chamber 3, the below that pedestal 1 is positioned at working chamber 3 is provided with spring base 7, be provided with Compress Spring 8 between spring base 7 and the conducting strip 5, and conducting strip 5 is connected by securing member with an axial end of Compress Spring 8, pedestal 1 is provided with spring base placed cavity 12, spring base 7 is positioned over also can be along the 12 axial reciprocating slippages of spring base placed cavity in the spring base placed cavity 12, and spring base 7 is provided with the spring base regulating part 9 that extends to outside the pedestal 1 with respect to the other end place with Compress Spring 8 conflicts one end.In the such scheme, by at pedestal 1 the spring base regulating part 9 that extends to outside it being set, the spring base placed cavity 12 interior positions that make spring base 7 be in pedestal 1 can change by sounding along with the adjusting of spring base regulating part 9, be that the axial location that spring base 7 is in the spring base placed cavity 12 can change, make the compression distance of Compress Spring 8 adjusted, thereby make the opening speed of jettron controlled.
In the utility model embodiment, spring base regulating part 9 includes the adjusting screw(rod) that is threaded engagement with spring base 7.Arrange so simple in structure, easy to operate; Certainly, need to prove that spring base regulating part 9 also can be set to position stop piece, spring base 7 is gear with it and cooperates and can implement equally to regulate.
In the utility model embodiment, in order to make the conflict between spring base 7 and the Compress Spring 8 more compact, can effectively place Compress Spring 8 in use occurs to swing or skew, the pressure section 72 that spring base 7 among the utility model embodiment includes location division 71 and is connected with location division 71, its location division 71 is arcuation, and pressure section 72 is discoid body.Location division 71 is inserted in Compress Spring 8 inside, and pressure section 72 then is used for Compress Spring 8 is implemented to compress.
