Abstract
The utility model discloses a single pressure switch incapable of being automatically reset. The single pressure switch incapable of being automatically reset comprises a bracket; an insulation column and an adjusting screw are respectively arranged on the bracket; a first wiring terminal, an upper spring piece, a second wiring terminal, a wafer head and a pressure switch bottom elastic piece are from top to bottom sequentially sleeved on the insulation column; porcelain gaskets are respectively arranged between the bracket and the first wiring terminal, between the upper spring piece and the second wiring terminal, and between the wafer head and the pressure switch bottom elastic piece; a rivet is arranged on the insulation column; and control switches are arranged on the upper spring piece and the wafer head. According to the single pressure switch incapable of being automatically reset provided by the utility model, triangular force balance among a first porcelain rod, the upper spring piece, and a lower spring piece enables the pressure switch not to be reset automatically, operation of the pressure switch can then be totally stopped, security performances of the pressure switch can be greatly improved, and the ultimate protection of an electric pressure vessel can be realized.
Description
Technical field
The utility model relates to a kind of single pressure switch that can not automatically reset.
Background technology
A kind of common control mode of controlling the electric pressure cooker internal pressure is to adopt automatically reset single pressure switch to control.Automatically reset single pressure switch contacts to control pressure in electric pressure cooker by a pair of electric contact.Can separate by electric contact when the pressure in electric pressure cooker arrives some strength and reduce pressure, the electric contact contact that can automatically reset when pressure decreased.This single contact automatic reset switch can not stop pressure switch work fully, in case and its control switch of contact failure just can complete failure, produce dangerous.
Summary of the invention
In order to address the above problem; the novel purpose of this use is to provide a kind of single pressure switch that can not automatically reset; its triangle balance by power between the first porcelain rod, upper spring sheet, lower spring sheet can not automatically reset pressure switch; thereby can stop pressure switch work fully; greatly improve the security performance of pressure switch, and realized the ultimate protection of Voltage force container.
The utility model is the purpose that reaches above-mentioned, and the utility model adopts following technical scheme:
A kind of single pressure switch that can not automatically reset comprises support, is separately installed with insulated column and adjustment screw on described support; Wherein from top to bottom be socketed with successively shell fragment at the bottom of the first binding post, upper spring sheet, the second binding post, contact head and pressure switch on insulated column, and between described support and the first binding post, between upper spring sheet and the second binding post, be separately installed with the porcelain packing ring at the bottom of contact head and pressure switch between shell fragment, on described insulated column, rivet be installed; On described upper spring sheet and contact blade, control switch is installed.
Described control switch comprises upper spring sheet, lower spring sheet, upper silver contact, lower silver contact, the first porcelain rod and the second porcelain rod; Wherein said lower silver contact and contact blade are connected; Described upper silver contact and lower spring sheet one end are connected, and the other end of lower spring sheet, upper spring sheet be connected with the second porcelain rod respectively, and at the bottom of described pressure switch, shell fragment and the second porcelain rod are connected; Described the first porcelain rod one end passes support and is connected with adjustment screw, and its other end is connected with the upper spring sheet.
At the bottom of described pressure switch, shell fragment is connected with adjusting screw(rod) by copper sheathing.
Under shell fragment, lower carriage is installed at the bottom of described pressure switch.
The beneficial effects of the utility model are: the utility model provides a kind of single pressure switch that can not automatically reset; its triangle balance by power between the first porcelain rod, upper spring sheet, lower spring sheet can not automatically reset pressure switch; thereby can stop pressure switch work fully; greatly improve the security performance of pressure switch, and realized the ultimate protection of Voltage force container.

Embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of single pressure switch that can not automatically reset, and comprises support 2, is separately installed with insulated column 1 and adjustment screw 3 on described support 2; Wherein from top to bottom be socketed with successively shell fragment 8 at the bottom of the first binding post 4, upper spring sheet 5, the second binding post 6, contact head 7 and pressure switch on insulated column 1, and between described support 2 and the first binding post 4, between upper spring sheet 5 and the second binding post 6, be separately installed with porcelain packing ring 9 at the bottom of contact head 7 and pressure switch between shell fragment 8, on described insulated column 1, rivet 13 be installed; On described upper spring sheet 5 and contact blade 4, control switch is installed.At the bottom of described pressure switch, shell fragment 8 is connected with adjusting screw(rod) 16 by copper sheathing 17.At the bottom of described pressure switch, shell fragment is equipped with lower carriage 18 8 times.
Described control switch comprises upper spring sheet 5, lower spring sheet 10, upper silver contact 11, lower silver contact 12, first porcelain rod the 15 and second porcelain rod 14; Wherein said lower silver contact 12 is connected with contact blade 7; Described upper silver contact 11 is connected with lower spring sheet 10 1 ends, and the other end of lower spring sheet 10, upper spring sheet 5 be connected with the second porcelain rod 14 respectively, and at the bottom of described pressure switch, shell fragment 8 and the second porcelain rod 14 are connected; Described the first porcelain rod 15 1 ends pass support 2 and are connected with adjustment screw 3, and its other end is connected with upper spring sheet 5.
A kind of can not the automatically reseting during single pressure switch of using that the present embodiment provides, can be first make formation triangle dynamic balance between the two ends three of the contact point of the first porcelain rod 15 and upper spring sheet 5 and upper spring sheet 5 by adjustment screw 3.When the pressure in electric pressure cooker increases over safe pressure or the pressure switch that automatically resets inefficacy, the pot body deformability promotes the end that shell fragment 8 at the bottom of pressure switch is equipped with adjusting screw(rod) 16, and deformation upwards just can occur, upper silver contact 11 separates with second time silver contact 12 when it arrives certain deformation, thereby cuts off the electricity supply.When upper spring sheet 5 contacts with lower spring sheet 10, form new triangle dynamic balance between the two ends three of the contact point of the first porcelain rod 15 and upper spring sheet 5 and upper spring sheet 5, lower spring sheet 10.On this moment, silver contact 11 can not reset because of reducing of pressure with lower silver contact 12 and contact, and pressure switch quits work fully.
A kind of single pressure switch that can not automatically reset of the present embodiment manufacturing; its triangle balance by power between the first porcelain rod, upper spring sheet, lower spring sheet can not automatically reset pressure switch; thereby can stop pressure switch work fully; greatly improve the security performance of pressure switch, and realized the ultimate protection of Voltage force container.
