Abstract
The utility model relates to a switch, and particularly relates to a pneumatic switch. The utility model provides the following technical scheme thatthe pneumatic switch comprises a switch body, a bracket erected on the switch body and a pneumatic opening component which is erected on the bracket and is in linkage with the switch body. The pneumatic opening component comprises an opening valve. A working cavity is arranged between the opening valve and the bracket. The opening valve is provided with an air inlet which is communicated with the working cavity. The working cavity is internally provided with a guide plate, a film and a transmission part positioned at a lower part of the guide plate. One end of the transmission part is in linkage connection with the guide plate, and the other end of the transmission part and the switch body are in intermittent contact or separation. A joint of the bracket and the opening valve is provided with a clamping cavity. An edge of the film is provided with a clamping sealing part which is clamped in the clamping cavity at the joint of the bracket and the opening valve. By employing the above technical scheme, the pneumatic switch with convenient installation, simple structure, good sealing performance and long service life is provided.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of jettron.
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 jettron that occurs on market and the data is mainly by Switch main body, be set up in the support on the Switch main body and be set up on the support and with the pneumatic opening assembly of Switch main body interlock, pneumatic opening assembly includes open valve, be provided with working chamber between open valve and the support, open valve is provided with the air inlet with the working chamber conducting, be provided with positioning disk in the working chamber, be located at the diaphragm of positioning disk upper end and be in the driving member of conductive plate bottom, one end and the positioning disk of this driving member are connected, the other end then is intermittent conflict with Switch main body or separates, thereby consists of the switching of Switch main body; Diaphragm is the sealing shutter member in the open valve, and its edge is installed with between support and open valve, and use can cause the diaphragm edge fracture or reveal for a long time, and open valve can't be worked normally, and Switch main body also can not get opening normally or closing.
Summary of the invention
For the deficiency that prior art exists, it is a kind of easy for installation, simple in structure that the utility model provides, good airproof performance, the jettron of long service life.
For achieving the above object, the utility model provides following technical scheme: a kind of jettron, include Switch main body, be set up in the support on the Switch main body and be set up on the support and with the pneumatic opening assembly of Switch main body interlock, pneumatic opening assembly includes open valve, be provided with working chamber between open valve and the support, open valve is provided with the air inlet with the working chamber conducting, be provided with positioning disk in the working chamber, be located at the diaphragm of positioning disk upper end and be in the driving member of conductive plate bottom, one end and the positioning disk of this driving member are connected, the other end then is intermittent conflict with Switch main body or separates, it is characterized in that: the joining place of described support and open valve is provided with the clamping chamber, the edge of diaphragm is provided with the clamping seal, and the clamping seal is connected in the clamping chamber of support and open valve joining place.
Adopt technique scheme, by the clamping chamber is set between support and open valve, and diaphragm is arranged between support and the open valve by the clamping seal of its edge, after arranging like this, the edge of diaphragm is not only fixing comparatively firm, and can be owing to using and sounding fracture or leakage for a long time, improved the useful life of diaphragm, simultaneously also make jettron can be in normal operating state, and such arrange simple in structure, good airproof performance.
The utility model further is set to: support is connected the clamping chamber that is in open valve inwall is provided with the dentation location sealing post that is the multi-point fitting sealing with the clamping seal.
Adopt technique scheme, the sealing of multiple spot has improved gas tightness, and dentation location sealing post can implement the location to the clamping seal, makes being between open valve and the support that diaphragm can be more stable.
The utility model further is set to: the clamping seal is cross section seal in the form of a ring.
Adopt technique scheme, be provided with like this and help improve diaphragm stability in use.
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 jettron as shown in Figure 1, include Switch main body 1, be set up in the support 2 on the Switch main body 1 and be set up on the support 2 and with the pneumatic opening assembly 3 of Switch main body 1 interlock, pneumatic opening assembly 3 includes open valve 31, be provided with working chamber 4 between open valve 31 and the support 2, open valve 31 is provided with the air inlet 32 with working chamber 4 conductings, be provided with positioning disk 33 in the working chamber 32, be located at the diaphragm 34 of positioning disk 33 upper ends and be in the driving member 35 of conductive plate 33 bottoms, one end and the positioning disk 33 of this driving member 35 are connected, and the other end then is intermittent conflict with Switch main body 1 or separates.Support 2 is provided with clamping chamber 5 with the joining place of open valve 31, and the edge of diaphragm 34 is provided with clamping seal 341, and clamping seal 341 is connected in the clamping chamber 5 of support 2 and open valve 31 joining places.In the such scheme, by between support 2 and open valve 31, clamping chamber 5 being set, and diaphragm 34 is arranged between support 2 and the open valve 31 by the clamping seal 341 of its edge, after arranging like this, the edge of diaphragm 34 is not only fixing comparatively firm, and can be owing to using and sounding fracture or leakage for a long time, improved the useful life of diaphragm 34, simultaneously also make jettron can be in normal operating state, and such arrange simple in structure, good airproof performance.
In the utility model embodiment, support 2 is connected the clamping chamber 5 that is in open valve 31 inwall is provided with the dentation location sealing post 311 that is the multi-point fitting sealing with clamping seal 341, and dentation sealing column 311 is located on the open valve 31, certainly, also can be located on the support, all be feasible.The sealing of multiple spot has improved gas tightness, and dentation location sealing post 311 can implement the location to clamping seal 341, makes being between open valve 31 and the support 2 that diaphragm 34 can be more stable.And, the stability when using in order to improve diaphragm 34, clamping seal 341 is cross section seal in the form of a ring.
