Turntable

Abstract

The invention provides a turntable comprises a rotating disc in relative rotational motion and a fixed disc. The turntable is characterized in that an upper pressure plate is fixed on the rotating disc; a slot for limiting position is opened on the side wall of the upper pressure plate; an unlocking plate is rotatably riveted on the rotating disc through a turntable step rivet; the unlocking platerotates relative to the rotating disc with the turntable step rivet as the origin; the unlocking plate contacts and cooperates with the slot to achieve overall limit of the turntable; a hanging spring plate is fixed on the unlocking plate; a hanging spring pin is fixed on the fixed disc; a spring is mounted on the hanging spring plate and the hanging spring pin. The turntable has the advantages that the unlocking plate can smoothly rotate relative to the rotating disc; limit locking is very reliable with the unlocking plate and the slot of the upper pressure plate contacted and cooperated with each other to realize the overall limit of the turntable; with the restoring force of a tension spring, the unlocking plate can always be in the state of eliminating the gap between the fixed disc and the rotating disc, the amount of work required to unlock is significantly reduced, which allows users to use the product effortless and worry-free.

Description

technical field [0001] The invention relates to the field of seat devices, in particular to a turntable for seat rotation adjustment. Background technique [0002] With the rapid development of automobile technology, people's requirements for cars have gradually shifted from the initial simple means of transportation to the enjoyment of daily life. Cars generally do not have seat swivel adjustments. However, most commercial vehicle models have enough space to rotate the middle seat by 180°, which can ensure that the passengers and rear passengers can talk face to face, so there is a demand for the rotating function of the seat, and the rotating disk in the current market is suitable The seat is small and light in weight, and the strength and durability of the rotating disk cannot meet the needs of the modified seat, mainly because the unlocking operation of the existing rotating disk is strong and the limit lock is not reliable.
