[0031] Refer to Figures 1 to 6 , Figure 1 is the perspective view of the present utility model, Figure 2 is the exploded view of the present utility model, Figure 3 is the front view of the present utility model, Figure 4 is the right view of the present utility model, Figure 5 is the left view of the present utility model, Figure 6 is the bottom view of the present utility model. An integrated headrest guide sleeve with a locking function provided by the present utility model includes a guide sleeve body 1, an unlocking button 2, and a retaining spring 3. The guide sleeve body 1 has a hollow structure for inserting a headrest rod. The retaining spring 3 is preferably a V-shaped retaining spring. The retaining spring 3 is fixedly connected to the unlocking button 2 by insert molding, which improves the structural strength of the unlocking button 2. The unlocking button 2 is snap-fitted with the guide sleeve body 1.

[0032] The guide sleeve body 1 is provided with a cover 11, an anti-misassembly part 12, a clamping block 13, an elastic sheet 14, an opening 15, a convex part 16, a reinforcing rib 17, and a limiting groove 18. The cover 11 and the guide sleeve body 1 are integrally formed. On the premise of realizing the function of the headrest guide sleeve, the number of assembly parts is reduced and the manual assembly man-hours are reduced. The upper part of the guide sleeve body 1 is provided with a limiting groove 18 for limiting the stroke of the unlocking button 2. The lower part of the unlocking button 2 is provided with a guiding piece 21, and the guiding piece 21 moves in the limiting groove 18. The limiting groove 18 and the guiding piece 21 are preferably arranged in pairs. The unlocking button 2 with a snap spring 3 is inserted into the cover 11 and clamped with the guide sleeve body 1. The anti-misassembly part 12 is arranged on the outer side of the upper part of the guide sleeve body 1. The anti-misassembly part 12 is preferably set to be four-sided anti-misassembly, that is, there are four different convex platform structures arranged oppositely in a cross shape, which can effectively prevent misassembly problems. The clamping blocks 13 are symmetrically arranged at the lower part of the guide sleeve body 1. The clamping blocks 13 are used for clamping the guide sleeve body 1 with a metal sleeve to fix the guide sleeve body 1. The elastic sheet 14 is formed at the lower part of the guide sleeve body 1. At the same time, openings 15 are formed on both sides of the elastic sheet 14, which increases the elasticity of the guide sleeve body 1 and makes the fit with the headrest rod closer, prevents the headrest rod from shaking, and is more convenient for assembly and disassembly. The convex part 16 is arranged on the guide sleeve body 1 and protrudes inward. The convex part 16 is used for fixing the headrest rod to make the fit between the guide sleeve body 1 and the headrest rod closer. The convex part 16 includes a fixed convex part 161 and an elastic convex part 162. Through grooves 163 are formed on both sides of the elastic convex part 162. The convex part 16 increases the elasticity of the guide sleeve body 1, and at the same time, the through grooves 163 also have the effect of reducing weight. The reinforcing ribs 17 are arranged inside and outside the guide sleeve body 1. The reinforcing ribs 17 include transverse reinforcing ribs 171 and longitudinal reinforcing ribs 172. The reinforcing ribs 17 can not only play a role in strengthening the strength but also make the fit between the guide sleeve body 1 and the metal sleeve and the headrest rod closer, preventing the headrest rod from shaking.

[0033] The following will refer to Figures 1 to 6 to illustrate the working principle of the present invention.

[0034] The integrated headrest guide sleeve of the present invention realizes the headrest unlocking function through the unlocking button 2. The Y-direction force pushes the unlocking button 2, compresses the V-shaped snap spring 3, and pushes the unlocking button 2 out of the headrest rod slot, unlocking the Z-direction limit of the headrest and realizing the headrest height adjustment function; when the Y-direction force on the unlocking button 2 is released, the unlocking button 2 is reset under the internal stress of the V-shaped snap spring 3, realizing the locking of the headrest rod and restricting the Z-direction movement of the headrest rod. The integrated headrest guide sleeve of the present invention has reasonable design, few parts, simple structure, good system stability, less manual assembly man-hours, convenient operation, lower manufacturing cost, and beautiful appearance.

[0035] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
