Description
Technical field
The invention belongs to Domestic refrigerator field, relate to a kind of temperature controller, specifically a kind of main lever shell mechanism of temperature controller
Background technology
Temperature controller is to promote the through and off of contact with pressure action principle.Its structure by induction system, pass on signal system and lever balance system and form.The drift of thermostat temperature parameter primarily of induction system refrigerant purity, pass on the flexibility of signal dynamical system and lever balance system reliability and determine.The refrigerant purity of system, signal system of passing on utilize current technology and equipment can ensure completely, but the level of processing of lever balance system suffers in current state inner mold and the defect of structural design own, all the time fail to solve, become the technical barrier of general character in the industry.
At present, main lever shell mechanism 1.2 and main lever 1.1, as shown in Figure 1, Figure 2, Figure 3 shows, the defect that main lever shell mechanism 1.2 exists: is main lever point 2.1 bending to the inside, main lever 1.1 easily interferes with main lever point 2.1 place of main lever shell mechanism 1.2.Two are fulcrum 2.2 shapes on main lever point 2.1 top is by mold cutouts self-assembling formation, and its fulcrum shape forms the plane of 0.25mm width.Main lever 1.1 operationally, will produce two fulcrum A and B that do not exist together, and causes main regulations and parameters system balancing to change, and formation temperature is drifted about.
Summary of the invention
The object of the present invention is to provide a kind of main lever shell mechanism of temperature controller.
Object of the present invention can be achieved through the following technical solutions:
A kind of main lever shell mechanism of temperature controller, comprise main lever and shell, described shell comprises left shell, the right shell body of back casing and the connection of back casing both sides, left shell and right shell body are oppositely arranged, described left shell and right shell body are provided with two corresponding square openings, the denation projected upwards is equipped with bottom described two square openings, described main lever both sides are equipped with rectangular cam, rectangular cam side is provided with triangular groove, described triangular groove and denation suitable.
Described denation top is that arc surface is arranged, and arc radius precision is ± 0.1mm, and the contact site on denation and square opening base is that fillet is arranged.
Four edges of described square opening are that fillet is arranged.
The vertical direction axis of described square opening and the axis being parallel of back casing.
The lateral surface of described denation is provided with annular projection.
Two sides of described left shell and right shell body are horizontal plane.
Beneficial effect of the present invention: the left shell and the right shell body that present invention employs the setting of flat main body cover, the summit of the denation simultaneously arranged is arc surface, eliminate the problem of interference, the fulcrum intensity of denation is considerably beyond the structural strength of traditional hangers type, and the present invention has good effect to the quality of product, performance.

Fig. 2 is main lever structural representation in prior art.
Fig. 3 is prior art central bearing point structural representation.
Fig. 4 is shell mechanism schematic diagram of the present invention.
Fig. 5 main lever structural representation of the present invention.
Embodiment
As shown in Figure 4, Figure 5, a kind of main lever shell mechanism of temperature controller, comprise main lever and shell, described shell comprises left shell 2, the right shell body 3 of back casing 1 and the connection of back casing 1 both sides, left shell 2 is oppositely arranged with right shell body 3 and the structure of two is all identical, described left shell 2 and right shell body 3 are provided with two corresponding square openings 4, the vertical direction axis of described square opening 4 and the axis being parallel of back casing 1.The denation 5 projected upwards is equipped with bottom described two square openings 4.Described main lever both sides are equipped with rectangular cam 7, and rectangular cam 7 side is provided with triangular groove 8, and described triangular groove 8 is suitable with denation 5.Described denation 5 top is that arc surface is arranged, and arc radius precision is ± 0.1mm, and denation 5 is that fillet is arranged with the contact site on square opening 4 base.Four edges of described square opening 4 are that fillet is arranged.The lateral surface of described denation 5 is provided with annular projection 6.Described left shell 2 is horizontal plane with two sides of right shell body 3, have employed flat main body cover and arranges.
For overcoming the problem occurring two fulcrums main lever 1.1 easily to interfere with it in action during at main lever point 2.1 place, the left shell 2 that the shell that present invention employs flat main body is arranged and right shell body 3, as Fig. 4, denation 5 fulcrum on its square opening 4 is by the direct die-cut arc surface forming R0.1 of mould, triangular groove 8 on the rectangular cam 7 be provided with main lever both sides is suitable, triangular groove 8 is also by the direct die-cut arc surface forming R0.1 of mould, denation 5 solves with the combination of triangular groove 8 problem that in prior art, two fulcrums interfere.Owing to being left shell 2, the right shell body 3 of flat, being different from the technical pattern of Fig. 1 Central Plains housing shoulder type, also eliminating the problem of interference.The advantage that another one is outstanding, adopt the structure of the shell of flat, its denation 5 fulcrum intensity is considerably beyond the structure of hangers type.During work, denation 5 would not produce two fulcrums do not existed together with the combination of triangular groove 8, thus main regulations and parameters system balancing can not be caused to change, and formation temperature is drifted about.So the present invention has good effect to the quality of product, performance.
The present invention is directed to the defect of prior art, in order to avoid the generation of two fulcrums " A " and " B ", meet stamping forming needs simultaneously, we have employed flat body type case, the technical scheme that breakthrough " removing hangers " is designed, designs the triangular groove 8 of main lever in the plane of housing, adds the intensity of fulcrum, eliminate the interference problem of " removing hangers " structure simultaneously, reduce cost of stamping.In addition, adopt " removing hangers " structure, the assembling of enclosure interior part is convenient and freely.The per day assembling quantity of the single workman of assembling of product reaches 1000, is about 600 in the past.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
