Description
Technical field
The utility model relates to a kind of mechanical temperature controller, especially forces action to come the disconnected by force pressure temperature controller of mechanical type of control apparatus break-make.
Background technology
At present; the electric temperature regulator type thermostat that is used for the refrigerator refrigerator; its control principle is by the capillary temperature-sensitive; utilize the saturated gas in its injection capillary temperature-sensitive chamber; when variations in temperature, produce and expand or contraction; pressure following temperature in the temperature-sensitive chamber is changed; this pressure changes and causes the bellows motion; by the mechanical transmission mechanism effect; automatically moment is switched on or switched off the main contacts in the thermostat; and reach control start-stop compressor, as reaching the forced stoppage state, need to realize by disconnecting auxiliary contact or positive closing power supply.As the patent No. is 02249191.0, patent name is the patent of the explosion-proof type compression-type temperature controller of band auxiliary switch, change patent bellows, bearing plate, temperature adjustment extension spring, switch enclosure, dividing plate, binding post and contact assembly are housed in main body, be provided with two boss in dividing plate central authorities middle and upper part, it highly is not less than 6mm; Cylindrical push rod cooperates with the boss round tube hole, and wherein push rod two ends contact with bearing plate point with movable contact spring respectively, and another push rod one end contacts with auxiliary contact, and the other end contacts with cam by auxilliary sheet handle; Epoxy sealing is all used at switch enclosure and dividing plate junction surface, binding post and switch enclosure junction surface.But this structure is wanted three binding posts, also will add a cover dynamic/static contact, auxiliary push-rod, increased cost, and many times the 3rd contact uses seldom, also causes the possibility of wrong plug easily.
Summary of the invention
The utility model has solved product cost height of the prior art, and the shortcoming that technical matters is bad provides a kind of cost low, the disconnected by force pressure temperature controller of the mechanical type of good manufacturability.
Another purpose of the present utility model is to prevent that client's pin wrong plug in use from causing fault.
The technical scheme that its technical problem that solves the utility model adopts is: the disconnected by force pressure temperature controller of a kind of mechanical type, comprise the mechanical type controlling organization of disconnected pressure temperature controller by force, switch enclosure, bellows and temperature-sensitive portion, be provided with in the switch enclosure by moving, the single-pole single-throw switch (SPST) that fixed contact is formed, moving contact is by the contact reed, push rod links to each other with lever, wherein, the wheel face of described plane cam is provided with a block, projection on the position of block and the plane cam wheel rim in an angle, block on the plane cam on one end of lever and the body links to each other, and the rotation of plane cam can cause that the action of lever realizes the switching of switch.When exterior temperature change, the saturated steam in the capillary produces the variation of pressure, and the variation of this pressure causes the motion of bellows, thereby makes lever make push rod produce displacement under the effect of spring, thereby makes the main contacts contact or the disconnection of switch enclosure inside.The rotation of plane cam makes the block on the plane cam contact with lever is most advanced and sophisticated, makes lever produce displacement, thereby makes the push rod motion force the contact in the switch enclosure to disconnect, and reaches the purpose of shutdown; The action needs calculating meticulously that lever links to each other with plane cam and produces, it is particularly important that the position of the block on the plane cam seems, the determining positions of block the time and the distance of lever action, then the closure that influences the switch enclosure switch inside with open, projection on the plane cam can play the fixed pan action of cam, and can play positioning action when mounted and make the relative position of lever and plane cam more accurate.
Described switch enclosure is provided with two pins, is provided with single-pole single-throw switch (SPST) between two pins and constitutes a loop.Switch enclosure plays important effect as a protective device, adopts two pins to be not easy to obscure, the situation of pin wrong plug in can not occurring using.
The outward flange shape relation of the block on the plane cam is to the action of lever, and therefore the block on the described plane cam is a triangle, and leg-of-mutton edge is to meet the movement locus of required lever and edge that the arc that designs combines with straight flange.
Pin on the described switch enclosure divides C pin and L pin, picks out the contact reed of a bending from the C pin, and the contact leaf end is equipped with moving contact, and fixed contact is positioned on the L pin, the sound closing of contact or disconnection in the time of work.The contact reed has elasticity, and crooked back produces a restoring force, and the contact reed is withstood by push rod, the sound engage contacts, and push rod is recalled the back under the effect of restoring force, and the sound contact is separately.
No longer use the step of positive closing power supply or this shutdown of auxiliary contact, realize the folding of switch by link stopper on the plane cam and leverage, therefore, there is the transmission arm of a bending at the position that described lever links to each other with plane cam, the both sides of transmission arm and the limit of lever are vertical configuration, and the top of transmission arm is a circular arc.For the active force that guarantees the block transmission can be implemented on the transmission arm, can not produce and skid, so the both sides of transmission arm need be vertical configuration, the end is done in the arc-shaped.
Be delivered to the action of contact reed to the sound contact from the action of lever, wherein need the parts of a transmission, described push rod one end is arranged between the bending edges of the transmission arm of lever and lever, and the other end is arranged on the reed of contact.
The operating distance of push rod has influenced the joint and the disconnection of sound contact, distance between described push rod and lever and the contact reed matches, be that the space that push rod can be movable and the operating distance of transmission arm on projection of lever match, also and the distance between the dynamic and static contact match.
The beneficial effects of the utility model are: reduced a pair of sound contact, only use a pair of sound contact just can work normally, make structure simpler, the manufacturability aspect has also reduced requirement than original, and the material that adopts lacked, and has reduced whole cost, can close power supply shuts down and can not damage device and prolonged useful life, have only two pins on the switch enclosure, install on client's production line and be not easy to obscure the situation of pin wrong plug in the time of can not occurring using.
