Abstract

The invention relates to a double-locking headrest guide sleeve structure which comprises a headrest rod and a double-locking guide sleeve which is sleeved on the headrest rod in a locking fit manner,wherein the headrest rod is provided with a straight groove and a dovetail groove; the double-locking guide sleeve comprises a button, a guide sleeve body, a first locking piece and a second lockingpiece. Wherein the first locking piece installed on the guide sleeve body is locked with the straight groove in a matched mode, the second locking piece installed on the guide sleeve body is locked with the dovetail groove in a matched mode, and the button is installed on the guide sleeve body and acts on the first locking piece and the second locking piece at the same time to achieve simultaneousunlocking. According to the double-locking headrest guide sleeve structure, two locking structures are arranged, the locking strength of the headrest guide sleeve can be improved, the first locking piece and the second locking piece are driven by one button to be unlocked at the same time during unlocking, and the double-locking headrest guide sleeve structure is convenient and rapid to use.

Description

technical field [0001] The invention relates to locking of a headrest, and more particularly relates to a double-locking headrest guide sleeve structure. Background technique [0002] There is only one locking structure on the existing headrest guide sleeve, and the locking strength is limited. When the locking structure fails, the head restraint fails immediately.
