Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is made concrete further instruction.A kind of simple type oven hinge, it includes the main body 1 being arranged on chamber door and the hinge arms 2 being movably articulated in its top, hinge arms 2 buckle is fixed on casing, the most hinged in described hinge arms 2 torque arm 3 is installed, extension spring 4 it is provided with between torque arm 3 tail end and main body 1, main body 1 around hinge arms 2 rotate time, torque arm 3 slide anteroposterior in main body 1 can be driven, extension spring 4 pulls torque arm 3 to reset for it and closes chamber door offer power, it is characterized in that: in described torque arm 3, be provided with gathering sill 31, by support shaft 5, directive wheel 6 is installed in gathering sill 31, it is provided with torsion spring 7 in torque arm 3 to be directed to take turns 6 to the promotion of hinge arms 2 direction, directive wheel 6 is made to be pressed on the outline of hinge arms 2 slip all the time.

Described torsion spring 7 is sleeved on hinge 8 surface, and hinge 8 is fixed in torque arm 3.

A spike of described torsion spring 7 one end is fixed in torque arm 3, and a spike for the other end is fixed on hinge 8.

Operation principle: during this hinge assemblies, is fixed on main part on the chamber door of baking box, and hinge arms part is then arranged on casing.When in chamber door moving process, main part rotates around then its pin joint with hinge arms, and hinge arms pulls torque arm and extension spring campaign.When hinge is closed, extension spring produces reset force and can make hinge that chamber door can be driven to be automatically switched off.

Wherein, being provided with by the directive wheel of torsional-spring supported on the event trace of hinge arms 2, directive wheel, under the promotion of torsion spring, to the motion of hinge arms direction and is pressed against on the outline of hinge arms with certain pressure all the time.When hinge arms rotates, the buffering outer rim in hinge arms contacts all the time with directive wheel and slides on.In oven door closing process, the buffering outer rim in hinge arms constantly extrudes with directive wheel, and directive wheel serves the effect slowing down hinge reset speed, thus reduces door closing speed when hinge automatically resets.Wherein, in order to overcome the impact on cushion effect of the hinge acceleration at closing time, in this case, the torsion spring strong point in support shaft 5 can be along with the closedown of hinge arms, gradually move to hinge direction, under the effect of lever principle, the pressure that torsion spring is applied on directive wheel is gradually increased, with balance acceleration at closing time so that chamber door is steadily closed.
