Description

Technical Field

[0001] The utility model relates to the field of locking structures, in particular to a universal locking structure. Background Art

[0002] In modern furniture design, especially for seating products such as office chairs and leisure chairs, the adjustment between the chair back and the lever arm (or seat support arm) is adjusted through a locking structure.

[0003] Specifically, existing locking structures can usually only provide effective locking force in one direction (such as the forward or backward direction of the seat back relative to the lever arm), but lack sufficient stability in the other direction, causing the seat back to easily shake or shift when subjected to external forces, reducing the stability of the seat and the user experience. Existing locking structures are usually unable to achieve a two-way locking unlocking function through an unlocking connector. This means that when the user needs to adjust the seat back angle, they need to operate two or more locking components separately, which not only increases the complexity of the operation, but may also cause the user to damage the locking structure or the seat itself due to misoperation or improper operation during operation.

When the unlocking connector 4 is pressed to unlock the vertical rotating seat 1, an elastic force toward the circular joint 6 is generated to compress the first compression spring 11, so that the plug-in rod 19 The vertical rotating seat 1 is unlocked by separating from the socket 16, one end of the horizontal rotating seat 3 is recessed inward to form a plurality of slots 15, one end of the U-shaped fixed seat 2 is provided with a bayonet 17, one end of the unlocking connector 4 extends outward to form a fixing portion 21, and the end of the unlocking connector 4 close to the fixing portion 21 is provided with a horizontal unlocker 12, and a second compression spring 13 is provided inside the bayonet 17, one end of the second compression spring 13 is connected to the inner wall of the bayonet 17, and the other end of the second compression spring 13 is connected to the horizontal unlocker 12, and one end of the horizontal unlocker 12 extends to the inside of the slot 15. When the unlocking connector 4 is pressed to unlock the horizontal unlocker 12, the unlocking connector 4 compresses the second compression spring 13 to generate elastic force to move the horizontal unlocker 12 along the bayonet 17 to unlock the horizontal rotating seat 3.

[0022] The unlocking connector 4 is provided with an unlocking button 9 at one end away from the connecting portion 10. The unlocking connector 4 is unlocked or locked by pressing the unlocking button 9. The unlocking button 9 is provided so that the user can achieve the unlocking or locking function by a simple pressing action, which greatly simplifies the operation steps and improves the user's experience. The horizontal rotating seat 3 is provided with an axis core 18 extending in the vertical direction.
