Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-6, the present invention provides a quick release device for a headrest frame of an office chair, comprising:

a headrest assembly 10, the headrest assembly 10 includes a headrest 11, a support 12 and an adjusting seat 13, wherein the headrest 11 is pivotally connected to the support 12, and the support 12 can move up and down by the adjusting seat 13, the present invention mainly forms two parallel convex vertical sliding rails 1310 on the inner seat body 131 of the adjusting seat 13, the two sliding rails 1310 have convex insertion wings 1311, the seat body edge of the upper edge 1310 of the two sliding rails is provided with a horizontal abutting convex block 1312, the abutting convex block 1312 is larger than the outer diameter of the two sliding rails 1310, and the abutting convex block 1312 is provided with a notch 1313 in the middle, a convex embedding 1314 is provided between the two sliding rails 1310 near the abutting convex block 1312, the convex embedding 1314 is an inclined abutting shape gradually increasing from bottom to top, and the high end edge is a flat section 1315 with the same height as the two sliding rails 1310;

a fixing seat 20 having a butt-joint surface 21 opposite to the adjusting seat 13, the butt-joint surface 21 having a groove 22 with a closed bottom end, two sides of the groove 22 having concave embedding grooves 23, the width between the two embedding grooves 23 being suitable for the insertion wing 1311 of the two sliding rails 1310 to be sleeved, the fixing seat 20 having two locking holes 24 near the upper edge thereof to be locked on the frame of the chair back 30, in the embodiment, the two locking holes 24 are formed at the joint of the groove 22 and the two side flanges 25, and have a horizontal through hole shape with a surface lower than the groove 22 and the two side flanges 25 and having a stepped concave edge 241, a hook 26 is provided between the two locking holes 24, the hook 26 is an inclined shape that protrudes from the groove surface of the fixing seat 20 and is gradually opened from the top to the bottom, and the two sides and the bottom end of the hook 26 form a groove 261, so that the hook 26 can be properly elastically compressed by its plasticity, and the hook 26 can form a notch 261 from the back surface of the groove 261, so as to reduce the thickness of the hook 26, and the hook 26 can be hooked and positioned with the convex insert 1314 after being inserted into the inner seat 131 of the adjusting seat 13.

By the above components, when the adjusting seat 13 is combined with the fixing seat 20 by the inner seat body 131 thereof, because the inner seat body 131 thereof protrudes two vertical sliding rails 1310, and the two sliding rails 1310 are provided with the insertion wings 1311 in an outward convex shape, the insertion wings 1311 at both sides can be inserted into the recessed grooves 23 in both sides of the groove 22 of the fixing seat 20 in an inward concave shape, and because the bottom end of the groove 22 of the fixing seat 20 is a closed end and the abutting convex stops 1312 formed on the upper edges of the two sliding rails 1310 of the inner seat body 131, the fixing seat 20 and the inner seat body 131 can form an upper and lower abutting point after being sleeved, as shown in fig. 5, fig. 5 is a schematic diagram of the combined section of the inner seat body 131 and the fixing seat 20 of the novel adjusting seat 13, showing the state that the convex embedding hook 1314 of the inner seat body 13 is not hooked with the buckling hook 26 of the fixing seat 20, and when the inner seat body 131 is pressed downwards, the convex embedding point 1314 is inclined from the plane 1315 with the groove 26 of the fixing seat 20 in a high end edge toward the groove 1315 of the fixing seat 20 After compression, the hook 26 will elastically return to form a hook-and-loop positioning with the convex embedding 1314 after passing through the hook 26, so as to achieve the effect of fast assembly and stable combination. If it needs to be disassembled, since the abutting convex block 1312 on the upper edge of the inner base 131 is provided with a notch 1313, the hook 26 in the fixing base 20 can be compressed by the insertion of the column through the notch 1313, so that it and the inner base 131 can be retracted to the hooking state to achieve the effect of quick disassembly.

It should be noted that, since the fixing bases are locked on the backrest 30, when the user needs to assemble, the user only needs to put the adjusting base 13 of the headrest assembly 10 on the fixing base 20 to complete the positioning, and the assembly can be performed very quickly and accurately without any tool.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
