Abstract
The utility model relates to a cam shaft component mainly used for a fixed temperature resetting type pressure-type thermostat, which is composed of a cam shaft formed by integral injection molding, an elastic indication piece, a bracket and a spring washer, wherein, the elastic indication piece and the spring washer are sheathed on a plastic cam shaft passing through the bracket and downward pressed, the elastic indication piece is clamped and locked with a circular ring slot of the cam shaft, wherein, the rotary moment of the cam shaft is adjusted by the spring washer. The utility model has the advantage of simple and fast producing and assembling technologies and has double insulation effect. The electrical safety performance of a product is enhanced, and a grounding device of a conventional pressure type thermostat can be omitted.
Description
The utility model relates to the mechanical temperature controller technical field, the cam assembly that particularly a kind of compression-type temperature controller that is applicable to the electric temperature regulator type is used.
The cam assembly of used electric temperature regulator type compression-type temperature controller is made up of support 4, allumen edge cam 5, brass axle 1, indicating piece 2, spring washer 3 in the refrigerator at present, with successively and by desired position be enclosed within the axle 1 one ends edge cam axle 5, support 4, spring washer 3, indicating piece 2 rivet into cam assembly, referring to shown in Figure 1.The cam assembly parts of this kind metal construction are more, and production and assembling technology procedure are comparatively numerous and diverse, and because the material of axle is a conductive metallic material, must have ground structure could guarantee its electrical safety performance.
The cam assembly that provides a kind of compression-type temperature controller to use is provided the purpose of this utility model, and it not only can simplify production and assembling technology procedure, saving production cost, and can also make temperature controller obtain the double insulation performance, saves ground structure.
The purpose of this utility model is achieved in that the cam assembly that a kind of compression-type temperature controller is used, and comprises support, cam, axle, indicating piece, spring washer, it is characterized in that described cam becomes camshaft with the axle integral molded plastic; Described indicating piece is the elasticity indicating piece, and is installed on the camshaft.Described cam is an edge cam.On the axle of plastic cam shaft, be provided with annular groove and breach near cam.Described elasticity indicating piece is provided with that one group of annulus is arranged and independently a shell fragment and a lug mutually, and the annular groove clamping of this shell fragment group and plastic cam shaft is locked, and the breach of lug and plastic cam connects the location.The plastic material of camshaft preferably adopts glass-fiber reinforced nylon.
The course of work of this plastic cam shaft assembly is such: the rotating cam axle drives adjustable plate 6 and goes tractive extension spring 7, removes to regulate the displacement of corrugated tube by its spring deflection, thereby sets temperature required value.
Advantage of the present utility model is:
(1) simple and compact for structure, easy to use.
(2) assembly technology is simple, quick, the control accuracy height, and overall performance is stable.
(3) electrical security is strong.Because regulating shaft is common and the interior thermoregulation knob of refrigerator is used, and thermoregulation knob directly contacts with human body, is generally the assurance security performance, must add the ground connection device.And after adopting the plastic cam shaft modular construction,, add the insulation of upper knob because axle body has had insulation effect, so this structure has the double insulation effect, strengthened the product electrical safety performance, so can save the earthing device of temperature controller.
Fig. 1 is existing electric temperature regulator type compression-type temperature controller cam assembly structural representation.
Fig. 2 is the utility model cam assembly structural representation.
Fig. 3 is the vertical view of elasticity indicating piece shown in Figure 2.
The vertical view of camshaft shown in Figure 2 among Fig. 4.
Fig. 5 is the utility model cam assembly assembly structure synoptic diagram.
By following embodiment the utility model is further elaborated.
With reference to shown in Figure 2, partly be the cam assembly that the utility model electric temperature regulator type compression-type temperature controller is used in the double dot dash line frame among the figure, it is made up of camshaft 8, elasticity indicating piece 9, spring washer 3, the support 4 of integral molded plastic moulding.Plastic cam shaft 8 is made of axle 13 and edge cam 14 two parts, and used plastics are glass-fiber reinforced nylon.Be provided with a breach 15 and an annular groove 16 in axle 13 bottoms near cam 14 places, referring to shown in Figure 4.Elasticity indicating piece 9 is provided with that one group of annulus is arranged and independently a shell fragment 11 and a lug 10 mutually, and this group shell fragment 11 and horizontal plane angle are 30 ° of angles, and lug 10 matches with breach 15 sizes, referring to shown in Figure 3.Elasticity indicating piece 9 and spring washer 3 are enclosed within on the plastic cam shaft 8 that passes support 4 and exert pressure downwards, lug 10 on the elasticity indicating piece 9 just in time is stuck in the breach 15 on the plastic cam shaft 8, and shell fragment group 11 is locked with annular groove 16 clampings of plastic cam shaft 8, referring to Fig. 5 and shown in Figure 2.Because the elastic reaction of elasticity indicating piece 9 itself, elasticity indicating piece 9 and plastic cam shaft 8 are locked on the support 4, can not come off.Like this, when 8 rotations of adjustment cam axle, elasticity indicating piece 9 is rotation thereupon also, 12 usefulness that can be used as point of the tip of the tongue on it, by the tip of the tongue 12 and on groove can clearly aim at the position of indication end face cam 14 rotation exactly with the groove on the support 4.The effect of spring washer 3 is the turning moment of adjustment cam axle 8, can add a spring washer 3 in case of necessity.
