Abstract

The utility model particularly relates to a key driven kick thermostat, which comprises a switch base, a motion bar, a ceramic bar, platy springs, a bimetal, a left insertion end, a right insertion end, a movable contact spring, a moving contact and a fixed contact, wherein, the moving contact is connected to the movable contact spring; a component which is formed by the moving contact and the movable contact spring is connected to the right insertion end and then arranged inside a right groove of the switch base; the fixed contact is connected to the left insertion end; a component which is formed by the fixed contact and the left insertion end is arranged inside a left groove of the switch base; the movable contact spring is inserted into a positioning groove at the bottom of the switch base; the ceramic bar is arranged inside a cylindrical lug boss through hole of the switch base; the bimetal is arranged inside the positioning groove at the bottom of the switch base, and the central tongue end of the bimetal contacts the ceramic bar; and the platy springs are respectively inserted into grooves of the switch base and the motion bar. The key driven kick thermostat has the advantages of compact structure, accurate temperature control, flexible motion and having hand switch function.

Description

A kind of Kick type temperature controller

Technical field:

The utility model relates to the temperature controller technical field, refers in particular to a kind of button kick thermostat.

Technical background:

The configuration aspects of existing thermostat has the following disadvantages, the push rod design is at the edge of motion bar, determined the rigging position of bimetal leaf tongue end, the reliability of influencing contactor open and close, easily automatically reset, and push rod and the design of motion bar one, push rod length can't adapt to the deformation range of bimetal leaf tongue end, directly influences the temperature control accuracy.More than structural shortcoming make that existing thermostat thermometric is not accurate enough, mechanical breakdown easily takes place.

Summary of the invention:

The purpose of this utility model is the deficiency at existing thermostat, provide a kind of rational in infrastructure, temperature control thermometric accurately, be difficult for taking place the Kick type temperature controller of mechanical breakdown.

For achieving the above object, the technical scheme that the utility model provides is: include switch base, motion bar, ceramic bar, plate-shaped springs, bimetal leaf, left spigot, right spigot, movable contact spring, moving contact, decide contact, moving contact is connected on the movable contact spring, the assembly of above-mentioned moving contact and movable contact spring formation is connected on the right spigot, reinstalls in the right side groove of switch base; Decide contact and be connected on the left spigot, pack in the left side groove of switch base deciding assembly that contact and left spigot constitute; Movable contact spring is plugged in the location notch of switch base inner bottom part; Ceramic bar is packed in the cylinder boss through hole of switch base; Bimetal leaf is loaded in the location notch of switch base lower bottom part, and the tongue end in the middle of the bimetal leaf contacts with ceramic bar; Plate-shaped springs is inserted respectively in the groove of switch base and motion bar.

Advantage of the present utility model is: compact conformation, temperature control is accurate, is active in one's movements, and has the hand switch function.

Description of drawings:

Accompanying drawing 1 is a fractionation structural representation of the present utility model;

Accompanying drawing 2 is one of the utility model perspective view;

Accompanying drawing 3 is two of the utility model perspective view.

Embodiment:

See that accompanying drawing 1-is shown in Figure 3, present embodiment includes switch base 1, motion bar 2, ceramic bar 3, plate-shaped springs 4, bimetal leaf 5, left spigot 6, right spigot 7, movable contact spring 8, moving contact 9, decides contact 10, moving contact 9 is riveted on the movable contact spring 8, with this assembly staking on right spigot 7, in the right side groove of the switch base 1 of again this assembly being packed into; Decide contact 10 and be riveted on the left spigot 6, in the left side groove of the switch base 1 of again this assembly being packed into; Movable contact spring 8 is plugged in three location notchs of switch base 1 bottom; Ceramic bar 3 is packed in the cylinder boss through hole of switch base 1; Plate-shaped springs 4 is inserted respectively in the V-type groove of switch base 1 and motion bar 2, the two ends of flicking motion bar form closing of lever principle and disconnect the pass.

Operating principle of the present utility model is: thermostat motion bar 2 is in the low B of A end and holds (seeing shown in Figure 2) when high, if bimetal leaf 5 is subjected to extraneous temperature-sensitive, promptly deformation can take place, tongue end in the middle of the bimetal leaf 5 is the ceramic bar 3 of pushing installation in switch base 1 cylinder boss through hole initiatively, by the chain-wales of ceramic bar 3 promotions by the motion bar 2 of plate-shaped springs 4 supports, the A end of motion bar 2 is risen, because motion bar 2 is fixed on the intermediate support of switch base 1, the B end of motion bar 2 is depressed, at this moment, being molded over the movable contact spring 8 that plastic bar on the motion bar 2 will be packed in switch base 1 right side pushes, make moving contact 8 and decide contact 10 and separate, thereby cause circuit to be in off-state.When needs two closings of contact, as long as gently execute external force downwards at the A of motion bar 2 end, the plastic bar of motion bar 2B end will rise, and moving contact 10 is because of the elastic force effect, promptly with decide contact 10 and contact energising.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.
