Description

A kind of adjusting temperature controller

Technical field

The utility model relates to a kind of thermostat, refers to a kind of adjusting temperature controller that is used on temperature controls such as water heater, flatiron, electric furnace, baking box or the protection equipment especially.

Background technology

Thermostat is to promote the logical and disconnected of contact with the pressure action principle, thus the device that control apparatus equipment stops after reaching uniform temperature or starts working.Common thermostat mostly is adjusting temperature controller at present, promptly can adjust the break-make of thermostat under different temperatures by the temperature sensitive member of regulating thermostat self.As Fig. 7, Fig. 8, shown a kind of traditional adjusting temperature controller, primary structure comprises location meson 6, rotating shaft 7, bodice sheet 5, location meson 6 is fixed in the rotating shaft 7, rotating shaft 7 is connected with bodice sheet 5 by screw thread, the work angle of utilizing the location meson 6 and the collocation design of rotating shaft 7 to come the stroke and the thermostat of control rotating shaft 7, thermostat in the actual production work is many to be that make on the basis with the said structure, as a kind of automobile engine thermostat of Chinese utility model, patent No. ZL02279315.1, relate to automobile engine thermostat field, the bearing support that comprises shell and sandwich construction, each layer mutually insulated wherein, also be included in the bimetal leaf that is provided with on the bearing support of middle level and contact thereof and with the last binding post of bimetal leaf conducting; Be located at the adjustment screw on the bearing support of upper strata; Be located at conductor piece and following binding post and lower contact on lower floor's bearing support, binding post is serially connected on the engine ignition loop by line up and down, upper and lower contact is normally closed under design temperature, when the bimetal leaf heating temperature is higher than design temperature, bi-metal plate deformed, upper and lower contact is disconnected, cut off the power supply of engine ignitor.This utility model circuit contact is good, and good stability can effectively be avoided the engine overheat phenomenon.But described patent serviceability temperature adjustment screw is regulated the size to the bimetal leaf active force, and then the deformation temperature of control bimetal leaf, and degree of regulation, scope are influenced by adjustment screw thread spacing, and can not free indexing.Adjustable temperature controller for another Chinese utility model band heat protection function; patent No. ZL200820132011.5; comprise adjustable temperature controller part; adjustable temperature controller is partly by the thermal sensitive piece temperature distortion; up perk plays shell fragment by the porcelain vertex of a cone; make the moving contact on the shell fragment and the disconnection closure of the fixed contact on the contact chip reach temperature controlled function; this patent is by being located at the stroke that combines control rotating shaft between the location meson 6 in rotating shaft 7 and the rotating shaft directly over the porcelain awl; and then regulate the power that the porcelain knob be connected rotating shaft 7 belows acts on the shell fragment and control the deformation temperature of shell fragment, and utilize ridges different in the rotating shaft 7 apart from the angle of determining product.This utility model can be when thermostat itself can't cut off the power supply timely open circuit, avoid burning out other electrical equipment, but do not solve at room temperature yet, the thermostat rotating shaft is from the angle of minimum bit when dominant bit turns to closing of contact energising, be that bright lamp angular range is limited by the flight pitch of rotating shaft own, can not free adjustment, can't satisfy the requirement of client for bright lamp angular range.

The utility model content

One of the purpose of this utility model provides a kind of adjustable thermostat, and the bright lamp angular range that has solved traditional thermostat is limited by the flight pitch of rotating shaft own, the problem that bright lamp angle can not freely be changed, and the utility model rotating shaft can 360 ° of rotations.

Two of the purpose of this utility model is to solve the problem that existing thermostat temperature adjustment rotating shaft stroke is subjected to the flight pitch restriction of rotating shaft own.

The utility model is taked following technical scheme:

A kind of adjustable thermostat, comprise bodice plate rack 4, also comprise cam adjustment rotating shaft 1, Location resilient piece 2, bodice sheet shell 3, porcelain knob 11, bodice sheet shell 3 is riveted on the bodice plate rack 4 and with bodice plate rack 4 forms spacing cavity 22, cam adjustment rotating shaft 1 is arranged on the top of spacing cavity 22 and is passed down through bodice sheet shell 3, its bottom is arranged in the spacing cavity 22, porcelain knob 11 1 ends are socketed in cam adjustment rotating shaft 1 bottom, the other end is passed down through bodice plate rack 4, and Location resilient piece 2 is fixed on the sidewall of spacing cavity 22.

Described cam adjustment rotating shaft 1 is a cylinder axis, has the stroke curved surface of one or more projectioies, offers groove 20 on cam adjustment rotating shaft 1 side, and Location resilient piece 2 one ends are stuck in the groove 20.

Adopt adjustable thermostat of the present utility model, traditional rotating shaft and the collocation design of locating meson have been removed, use camshaft structure instead, the stroke of cam adjustment rotating shaft can be set the stroke curved surface as required and regulate on diverse location on the axle, no longer be subjected to the influence of rotating shaft tooth distance, it has the following advantages:

1, camshaft structure has been adopted in the adjustment rotating shaft, and the rotating shaft of cam adjustment can 360 ° of rotations, can regulate bright lamp angle arbitrarily, has enlarged the degree of freedom of the different gear temperature design of client's model machine, satisfies different clients' needs.

2, the utility model no longer is subjected to the influence of rotating shaft tooth distance, and the stroke of adjustment rotating shaft can be regulated by adjusting the position of stroke curved surface in the rotating shaft of cam adjustment, has enlarged the temperature controlled scope of thermostat, has increased the adaptability of product.
