Description

Technical Field

[0001] This application belongs to the field of seat manufacturing technology, specifically relating to a reclining mechanism locking device and a reclining seat. Background Technology

[0002] In the existing technology, the reclining chair plays a vital role in leisure and entertainment occasions, providing people with a comfortable resting experience and meeting their needs for physical and mental relaxation during leisure time.

[0003] However, current reclining chair locking devices on the market have some shortcomings. Existing technology makes it difficult or impossible for traditional reclining chairs to achieve a locking function, limiting their application to leisure and entertainment scenarios and making them unsuitable for daily office use. Furthermore, while some traditional reclining chair locking devices can achieve a certain degree of seat fixation, their locking structures are complex, with numerous components, making them prone to malfunction due to prolonged use or environmental factors. Once a malfunction occurs, repairs are difficult, affecting the normal use of the chair and reducing the user experience.

[0004] Furthermore, many existing reclining chairs have locking mechanisms that are poorly compatible with the overall chair design, failing to offer flexible adjustments based on different chair styles, sizes, and individual user needs. Moreover, during the locking process, the lack of sufficient cushioning and stabilization can cause the chair to wobble, produce noise, and even pose potential safety hazards to the chair itself and the user.

[0005] As people's pursuit of a higher quality of leisure life continues to increase, reclining chairs not only need to meet basic leisure needs in terms of functionality, but also require comprehensive improvements in safety, comfort, applicability, and convenience. Therefore, to comprehensively address the problems existing in current reclining chair locking devices, there is an urgent need for a stable, safe, reliable, and easy-to-operate locking device to enhance the overall performance of reclining chairs and the user experience, thereby meeting people's growing needs for leisure life. Utility Model Content

[0010] In some feasible embodiments, the traction assembly includes a connecting portion disposed on one end of the locking pin, and a traction portion disposed on the connecting portion. The traction portion is used to drive the connecting portion to move closer to or away from the locking hole, thereby driving the locking pin to move closer to or away from the locking hole.

[0011] In some feasible embodiments, the traction part includes a pull cable disposed on the connecting part and a drive button disposed on one end of the pull cable, the drive button being used to drive the pull cable to move away from the locking hole.

[0012] In some feasible embodiments, the connecting part includes a connecting spring disposed on one end of the locking pin and a ball head disposed on one end of the pull wire, the connecting spring being fitted onto the ball head and the ball head being engaged within the connecting spring.

[0013] In some feasible embodiments, the connecting part further includes a first connecting groove provided on the locking pin, and a first retaining spring provided on the first connecting groove. When the connecting spring is fitted onto one end of the locking pin, the first retaining spring abuts against the connecting spring to restrict the connecting spring from moving away from the locking pin, thereby making the connecting spring detachably provided on the locking pin.

[0014] In some feasible embodiments, the locking mechanism further includes a return spring disposed on the locking pin, the return spring being located between the two ear plates, the return spring being used to drive the locking pin to move toward the locking hole.

[0015] In some feasible embodiments, the locking mechanism further includes a second connecting groove provided on the locking pin, and a second retaining spring matchedly provided on the second connecting groove.
