Detailed description of the invention

Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of Novel baking oven hinge with chamber door locking function, it comprises the main body 1 be arranged on chamber door and the hinge arms 2 being movably articulated in its top, hinge arms 2 buckle is fixed on casing, also hinged in described hinge arms 2 torque arm 3 is installed, extension spring 4 is provided with between torque arm 3 tail end and main body 1, when main body 1 is rotated around hinge arms 2, torque arm 3 slide anteroposterior in main body 1 can be driven, extension spring 4 pulls torque arm 3 to close chamber door for its reset and provides power, it is characterized in that: in described main body 1, be also provided with the directive wheel 6 supported by spring 5, directive wheel 6 is pressed in the outer rim of hinge arms 2, and can at its surface sliding, described hinge arms 2 also arranges lock groove 21, when hinge is in closed condition, directive wheel 6 is snapped into this lock groove 21 internal fixtion.

Described lock groove 21 cross section is in " V " font.

The trapezoidal shape that described lock groove 21 cross section is big up and small down.

Described directive wheel 6 is arranged on support 61, and support can be arranged on the gathering sill 63 be positioned in main body 1 slidingly back and forth by rivet 62.

Described spring 5 is sleeved on support 61, and spring 5 two ends are pressed between support 61 and main body 1 respectively, is promoted by directive wheel 6 all the time to hinge arms 2 direction.

Operating 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 is rotated round the pin joint of itself and 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 automatically to close.

Wherein, be provided with on the surface of directive wheel by the directive wheel of resiliency supported, directive wheel can at hinge arms surface sliding, for reducing door closing speed when hinge automatically resets, in hinge arms, different contact surface is provided with in this case, make to extrude directive wheel in hinge closing process, produce the resistance of closing the door, make chamber door slowly closing.

Wherein it should be noted that, in order to prevent oven door, heat occurs after closedown and leak, cause the security incidents such as heat-energy losses or user are burned.In hinge arms, be provided with lock groove in this case, lock groove cross section is in " V " font or up big and down small trapezoidal shape.When hinge is in closed condition, directive wheel is just in time inserted in this lock groove, plays damping action when opening chamber door, thus avoids baking box to be in use subject to steam expansion in case and heat occurs leaking.In addition, the Cross-section that lock groove utilizes it special can play guide effect, make directive wheel snapping in after in it, the thrust of closing chamber door can be produced, make oven door have certain pressure all the time by being pressed on casing, thus produce the pretightning force of chamber door closedown, make oven door be in best sealing state all the time, therefore can baking box be widely used in, the equipment of the band such as micro-wave oven chamber door.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; as setting position and the Cross-section thereof of lock groove, these changes and improvements all fall within the scope of claimed the utility model.
