Description
Technical field
The utility model relates to a kind of switch, particularly a kind of open-interval jettron of controlling.
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 (machinery difference or hysteresis).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, end cap 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 high open-interval controlled jettron simple in structure, stable.
For achieving the above object, the utility model provides following technical scheme: a kind of open-interval jettron of controlling, include pedestal, end cap with the pedestal fastening, be provided with working chamber between end cap and the pedestal, end cap 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, diaphragm is provided with conducting strip towards the end face of working chamber bottom, 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 diaphragm, it is characterized in that: described pedestal is provided with installation cavity, spring base is in this installation cavity, and spring base includes can be along the fixing body of the installation cavity axial reciprocating of pedestal fine setting, and fixing body offers the standing groove of accommodating Compress Spring on the end face of working chamber.
Wherein, the utility model further is set to: the outer wall of fixing body is provided with screw thread, the inwall of pedestal installation cavity be provided with the fixing body outer wall on the adaptive screw thread of screw thread
Adopt technique scheme, but spring base is set to be with the pedestal installation cavity fixing body of axial adjustment, after arranging like this, the pressure of Compress Spring can be realized by the regulating spring seat, not only easy to operate, and need not to select specific Compress Spring, stability is higher, the setting of standing groove then is to implement the location for the axial end to Compress Spring on the fixing body, prevents that Compress Spring from swinging in the course of the work and have influence on the normal unlatching of switch.
The utility model further is set to: be provided with sealing ring between the installation cavity of fixing body and pedestal.
Adopt technique scheme, setting can guarantee the sealing of working chamber like this.
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.
Embodiment
A kind of open-interval jettron of controlling as shown in Figure 1, include pedestal 1, end cap 2 with pedestal 1 fastening, be provided with working chamber 3 between end cap 2 and the pedestal 1, end cap 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 diaphragm 4 of working chamber 3 axial reciprocating slippages, diaphragm 4 is provided with conducting strip 5 towards the end face of working chamber 3 bottoms, 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 diaphragm 4, pedestal 1 is provided with installation cavity 11, spring base 7 is in this installation cavity 11, spring base 7 includes can be along the fixing body of installation cavity 11 axial reciprocatings of pedestal 1 fine setting, and fixing body offers the standing groove 71 of accommodating Compress Spring 8 on the end face of working chamber 3.In the such scheme, but spring base 7 is set to be with pedestal 1 installation cavity 11 fixing body of axial adjustment, after arranging like this, the pressure of Compress Spring 8 can be realized by regulating spring seat 7, not only easy to operate, and need not to select specific Compress Spring 8, stability is higher, the setting of standing groove 71 then is to implement the location for the axial end to Compress Spring 8 on the fixing body, prevents that Compress Spring 8 from swing occuring in the course of the work and have influence on the normal unlatching of switch
In the utility model embodiment, the outer wall of fixing body is provided with screw thread, the inwall of pedestal 1 installation cavity 11 be provided with the fixing body outer wall on the adaptive screw thread of screw thread.Adopt spiral to spin between the installation cavity 11 of fixing body and pedestal 1, arrange so simple in structure, easy to process.Certainly, the axial adjustment between fixing body and pedestal 1 installation cavity 11 not only is confined to the adjusting of spiral, can at the installation cavity 11 interior positive stops that arrange, at the locating piece that fixing body setting can cooperate and get loose with positive stop, also be feasible also.In order to guarantee the sealing of working chamber 3, be provided with sealing ring 9 between the installation cavity 11 of fixing body and pedestal 1, sealing circle 9 is sheathed on the fixing body.
