Description
Technical field
The utility model relates to the Automatic Temperature Control field, relates to the structure of controller especially.
Background technology
Temperature controller switch is widely used in the various temperature operational environments of control automatically that need to realize, generally is made up of temperature-sensitive unit, performance element and shell body.The temperature-sensitive unit mainly comprises temperature sensing tube and capillary, be full of temperature-sensitive working medium in temperature sensing tube and the capillary, capillary one end is communicated with bellows, utilize the object principle of expanding with heat and contracting with cold, temperature-sensitive working medium sense ambient temperature in the temperature sensing tube, and expand with heat and contract with cold with the variation of ambient temperature, the bellows that is communicated with by capillary between this moment and the temperature sensing tube can be heaved or shrink accordingly, thus generation axial displacement variation.The change in displacement of bellows can make the movable contact spring of switch and static contact separately or set back by performance element, and then reaches the purpose of A.T.C.
Reed has important function in the performance element, by the reed movable contact spring of upspringing, the movable contact spring of switch and static contact is separated just.The reed of present temperature controller switch is connected on the switch base by special nonmetal reed seat, and reed and reed seat are directly injection-moulded in together usually, by screw reed seat and pedestal are fastenedly connected then, perhaps carry out riveted and fixed.Such connection technology is comparatively complicated, and product reliability is not high; And after the long-time use of temperature controller switch process, reed is prone to loosening phenomenon, influences accuracy of temperature control.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and the higher temperature controller switch of product reliability.
The utility model is that the technical scheme that achieves the above object is:
A kind of temperature controller switch, have pedestal and housing, be provided with bellows and push-rod assembly in the housing, bellows is communicated with the temperature-sensitive unit, is provided with spring assembly and dynamic and static contact in the pedestal, and the upper end of above-mentioned push-rod assembly contacts with bellows, the lower end of push-rod assembly contacts with spring assembly, above-mentioned spring assembly comprises reed and bow spring, and reed is plugged on the pedestal, and reed contacts with push-rod assembly.
Above-mentioned spring assembly comprises auxiliary stage clip, and auxiliary stage clip is located between pedestal and the reed.
Above-mentioned housing is provided with regulating shaft, and the lower end of regulating shaft contacts with bellows is adjustable.
Said base is provided with the stop screw that is used for limiting the reed lower position.
The inserted terminal of above-mentioned reed is provided with ratchet.
Benefit of the present utility model is that reed is connected on the pedestal by inserting mode, and the inserted terminal of reed is provided with ratchet, can guarantee firm being connected with pedestal of reed, has saved connection material and packaging process, and has improved reliability of products; Housing is provided with regulating shaft, and pedestal is provided with stop screw, both can regulate the control temperature of temperature controller switch, can regulate temperature controlled amplitude again, promptly can improve temperature controlled precision.

Embodiment
See Fig. 1, the utility model temperature controller switch has pedestal 1 and housing 2, and pedestal and housing are to being connected into integral body.Be provided with bellows 4 and push-rod assembly 5 in the housing, bellows is communicated with temperature-sensitive unit 3, and push-rod assembly 5 comprises push rod 51 and stage clip 52, and the upper end of push rod contacts with bellows, and stage clip is located between push rod and the housing.
See Fig. 2, Fig. 3, Fig. 4 and Fig. 5, be provided with spring assembly 6 and dynamic and static contact 7,8 in the said base 1, spring assembly comprises reed 61, bow spring 62 and auxiliary stage clip 63.Reed is plugged on the pedestal, and corresponding pedestal is provided with inserting groove 12, and the inserted terminal of reed is provided with ratchet 61-1, guarantees reed and pedestal firm plug.Reed have with push rod under the promotion point 61-2 of end in contact, promote point and move down after the push rod downforce being subjected to, and finally impel reed and movable contact spring contact jaw to rebound, flick movable contact spring and be connected with the conducting of static contact.Movable contact spring 7 is provided with the actuating strut 71 that contacts with reed, and the reed bounce-back contacts the movable contact spring of upspringing again with actuating strut.For better control precision, be provided with auxiliary stage clip 63 between reed and the pedestal, help the reed homing.
Above-mentioned housing 2 is provided with regulating shaft 21, by the rotation regulating shaft, can adjust the initial position of bellows 4, changes the relative position of push rod, changes the control temperature.Pedestal is provided with stop screw 11, and stop screw is positioned at reed 61 belows, can limit the extreme lower position of reed, and then regulates the amplitude of reed upset, finally reaches and improves the temperature control precision purpose.
When the utility model uses, at first change by temperature-sensitive unit 3 perception ambient temperatures, the temperature-sensitive working medium phenomenon of expanding with heat and contract with cold, when temperature raise, bellows 4 expansions were heaved.The axial location of bellows changes the transmission by push rod, affacts on the reed 61, and when the displacement of bellows acquires a certain degree, push rod will trigger reed and overturn, and flick movable contact spring then and be connected with the conducting of static contact.Otherwise when ambient temperature descended, bellows shrank, and lifts on the push rod, and reed resets, the conducting again of eastern contact and static contact.
