摘要： The present invention relates to the technical field of spring hinges, and to a silent spring hinge, which addresses the technical shortcoming that relatively high noise is generated when an existing spring hinge used in a household appliance drives a cabinet door to close. The silent spring hinge includes a fixing base, a hinge arm and a spring assembly, a damping assembly corresponding to a side edge of a rotating wheel being further provided on the fixing base, the damping assembly including a sleeve body, a steel ball, a spring and a lock nut, an outer wall of the sleeve body being snap-fitted on the fixing base, the steel ball, the spring and the lock nut being mounted within the sleeve body in sequence, a portion of the steel ball being exposed from the sleeve body and being elastically connected to the side edge of the rotating wheel, and a deceleration groove and a self-locking groove mated with the steel ball at a final stage of the process of closing a cabinet door being provided on a gear edge of the rotating wheel. By means of the present invention, the closing speed of the cabinet door is effectively reduced, and an effect of damping is achieved, such that the cabinet door is closed in a more stable manner, and a force of the spring assembly is not affected after the spring assembly drives the cabinet door to close. The present invention is particularly suitable for use on such products as ovens and microwave ovens.

摘要： The present invention relates to the technical field of spring hinges, and to a gear structure spring hinge, which addresses the technical shortcoming that a closing speed is excessively high when an existing spring hinge used in a household appliance drives a cabinet door to close. The gear structure spring hinge comprises a fixing base and a hinge arm, the fixing base being connected to a first gear through a first gear shaft, a crank shaft being provided on a gear surface of the first gear, the crank shaft being movably connected to a pull rod, a spring assembly being sleeved on the pull rod, a front end of the spring assembly being mated with and snap-fitted to the fixing base; and the hinge arm includes a connecting arm and a second gear, the second gear being provided on an end of the connecting arm, the second gear and the connecting arm forming an integral structure, the second gear being connected to the fixing base through a second gear shaft, the second gear being meshed with the first gear. Compared to the existing spring hinge, by means of the present invention, the closing speed of the cabinet door is effectively reduced, and an effect of damping is achieved, such that the cabinet door is closed in a more stable manner, and a force of the spring assembly is not affected after the spring assembly drives the cabinet door to close. The present invention is particularly suitable for use on such products as ovens and microwave ovens.
