Embodiment
The utility model is further elaborated by example below.
Referring to shown in Fig. 1 to Fig. 4, a kind of compression-type temperature controller forced shutdown structure, by body assembly 1, bellows lever group
Part 2, capsule stack 3, switch case assembly 4, monomer shutdown lever 5, adjustment axis 6, regulating cam of temp 7, shutdown cam 8, spring assembly 9
And sliding block 10 is constituted, switch module 4 is located at the lower right of body assembly 1, and capsule stack 3 is located at the lower left of body assembly 1, described
Adjustment axis 6, regulating cam of temp 7, the shutdown three of cam 8 stack riveting and are assemblied in into an entirety, and activity at an angle
On the bushing of body assembly 1, and it can make freely to rotate, the bellows lever 2 is supported on body assembly 1 by both sides fulcrum 201
On corresponding two side, half section of the right side of bellows lever 2 is cased with insulation sleeve and is connected with the main switch in switch module 4, promotes
Main switch is acted, and sliding block 10 is additionally provided with body assembly 1, and the sliding block 10 can be sliding by being located at the guide rail work left and right of body assembly 1
Dynamic, described one end of spring assembly 9 is connected with half section of the right side of bellows lever 2, and the other end of spring assembly 9 is connected with sliding block 10.If
There is monomer shutdown lever 5, the right part of monomer lever 5 is provided with double trapezoid structure anchor 502, and activity is connected to body assembly 1
Between bonnet and the rear wall for switching case assembly 4；It is additionally provided with monomer shutdown lever 5 bottom and cuts somebody's hair 501, with auxiliary switch reed
401 contact connections, inclined-plane 504 and limited block 503 are provided with monomer shutdown lever 5 top, and the inclined-plane 504 and the shutdown are convex
Take turns 8 sliding contacts connection.The monomer shutdown lever 5 uses injection molding.
The course of work of this compression-type temperature controller forced shutdown structure is as follows：
When temperature-sensitive temperature rises or falls, the expansion or shrinkage of capsule stack 3 pushes bellows lever 2 and put around fulcrum 201
Dynamic, the main contact switch of pull switch component 4 is switched on or switched off.If turning adjustment axis 6, sliding block 10 is with regulating cam of temp 7
Lift changes and changes position, the tensile force of spring assembly 9 is changed, so that temperature controller is operated in new temperature range
Circulation.
When adjustment axis is in temperature adjustment position, shutdown cam 8 is not in contact with monomer shutdown lever 5, auxiliary switch reed
401 elastic force boosts monomer and shuts down lever 5 to upper and auxiliary switch moving contact 402 is remained up with static contact 403.Work as temperature
When controlling the device hand-operated forced shutdown of needs, adjustment axis 6 is turned counterclockwise, and shutdown cam 8 goes to the inclined-plane for the lever 5 that shut down with monomer
504 contacts and its along inclined-plane climbing, monomer shutdown lever 5 is swung around fulcrum 502, and it, which is cut somebody's hair, 501 pushes down on auxiliary switch spring
Piece 401 makes moving contact 402 be disconnected with static contact 403, it is achieved thereby that forced shutdown function.
By rationally designing the double trapezoid size of fulcrum 502, can make monomer shut down lever 5 around fulcrum 502 have it is certain from
By pivot angle；By rationally design cut somebody's hair 501 position and spacing 503, it is ensured that monomer shutdown lever 5 is in as shown in Figure 1
Initial position；By rationally designing inclined-plane 504, monomer shutdown lever 5 can be made to obtain appropriate swing angle and stroke of cutting somebody's hair.
Because the fulcrum 502 of double trapezoid structure is stuck between the bonnet of body assembly 1 and the rear wall for switching case assembly 4, this installation position
Put makes fulcrum 502 not produce displacement, thus forced shutdown reliable in action with mounting structure, is not in failure phenomenon.
Above-mentioned technical proposal can also be applied to the constant temperature reset pressure type temperature controller or large on-off temperature of dual spring mechanism
Poor type compression-type temperature controller.
