A rack and pinion stabilizer system for a refrigerator drawer. The rack and pinion stabilizer system comprises a pair of drawer glides attached to first and second liner walls of a refrigerator. Each of the drawer glides has an attached rack gear with at least one tooth having an irregular profile. A pair of gear wheels having an axle therebetween are also provided. The gear wheels are provided in rotatable engagement with the rack gears and are capable of rotating in unison. An alignment mechanism is also provided. The alignment mechanism is attached to at least one of the rack gears for providing initial alignment of the first and second rack gears with the first and second gear wheels. Additionally, a drawer in operable communication with at least one of the drawer glides and axle is disclosed. When the drawer is inserted completely within the cabinet, the first and second gear wheels are positioned over the irregular teeth, providing a tolerance permitting closure of the drawer in the event of misalignment.

The invention discloses an automatic door closing device comprising boxes. Vertically-symmetric sliding cavities are fixedly arranged in the boxes, driving motors are fixedly arranged in the lower endwalls of the sliding cavities, upper and lower output shafts of the driving motors are connected with the end walls of the sliding cavities in a rotating fit mode, and threads are fixedly arranged onthe outer surfaces of output shafts of the driving motors; sliding blocks are arranged in matched connection with the threads of the output shafts of the driving motors, rotating cavities with openings facing the centerlines of the boxes are fixedly arranged in the sliding blocks, and a plurality of connecting rods are connected to the upper and lower end walls of each rotating cavity in a rotating fit mode; and main gears and worm gears are fixedly arranged on the outer surfaces of the connecting rods, rotating motors are fixedly arranged on the rear end walls of the rotating cavities, and worms connected with the front end walls of the rotating cavities in a rotating fit mode are fixedly arranged on the front end faces of output shafts of the rotating motors. The automatic door closingdevice is simple in structure and convenient to use; and the automatic door closing device achieves the efficient and automatic differential door opening and closing function through the worm gears, the worms and an irregular tooth type mechanism, and the using convenience and pleasure degree of users are improved.

A unidirectional ratchet wrench structure has a wrench member, a pawl and a ratchet. The wrench member has an accepting space for accommodating the ratchet and an accepting space for accommodating the pawl. A toothed section of the pawl has a plurality of equiangular teeth and an irregular tooth. Since the irregular tooth is lower than the height of the equiangular teeth, the irregular teeth irregular tooth is capable of quickly disengaging from the equiangular teeth of the ratchet. The arc section and the toothed section have different arc measures and not push against the outer periphery of the ratchet at the same time, through the abutment of the pivoting point and the change of the center of gravity of the pawl when the wrench is rotated, the pawl is capable of producing a seesaw yaw movement to achieves the effect of quick engagement and disengagement.

Disclosed is a toothed metal framework composite gasket having irregular teeth, comprising a metal framework having tooth-shaped protrusions and a non-metallic sealing material (6), wherein multiple circles of irregular teeth curved in the direction of a pressure source are distributed radially and concentrically along upper and lower end faces of the metal framework, which are covered by a filled non-metallic sealing material. Compared with conventional sealing teeth, new moon-shaped or bow-shaped teeth provide two additional resilient points and additional flexibility, preventing stress building up at two break points at a top part and a root part of the teeth, having relatively high anti-yielding and anti-fatigue performance, and increasing the service life of the gasket. Moreover, a pressure-prevention boss (4) is designed between the irregular teeth, preventing crushing and damage of the irregular teeth caused by excessive pre-stressing force, and ensuring security of sealing. The toothed metal framework composite gasket achieves extremely large improvements in elasticity, toughness, and compression resistance, has a relatively high elastic resilience and pressure bearing capacity, and will not be crushed and does not damage a flange.
