Referring to fig. 1-5, a chair back 1 mechanism with a neck pillow 2 capable of being adjusted in a lifting way, which can be used for a leisure chair or an electric competition chair, comprises a chair back 1 and a neck pillow 2. The back of the chair 1 is equipped with adjusts seat 3, adjust the slip track 4 that is equipped with extension from top to bottom on the seat 3 and slide assembly 5 on slip track 4,

slide assembly

5 and 2 fixed connection of neck pillow. The sliding connection assembly 5 is provided with a locking structure 5-A, the sliding track 4 is provided with a plurality of locking nodes 4-A which are arranged up and down at intervals, the locking structure 5-A can be jointed with the locking nodes 4-A, and the jointing force of the locking structure 5-A and the locking nodes 4-A has the maximum threshold value which can be destroyed by external force.

When the locking structure 5-A is jointed with a certain locking node 4-A, the neck pillow 2 is locked on the chair back 1, backward acting force is applied to the neck pillow 2 when the head or neck of a user is attached to the neck pillow 2, the joint state of the sliding connection assembly 5 and the sliding track 4 cannot be damaged, therefore, the state that the neck pillow 2 is locked on the chair back 1 is stable, when the height of the neck pillow 2 needs to be adjusted by the user, the joint state of the sliding connection assembly 5 and the sliding track 4 can be damaged by pushing the neck pillow 2 up and down with enough force, and the sliding connection assembly 5 can slide up and down along the sliding track 4. Therefore, the user can sit on the chair with the neck abutting against the neck pillow 2, and simultaneously press the neck pillow 2 with the hand to pull up and down the adjustment, the user can feel the change of the adjustment to determine the final adjustment position.

Based on promote neck pillow 2's regulation mode from top to bottom, the user can carry out neck pillow 2's altitude mixture control in the front of the 1 mechanism of the back of the chair, compares among the prior art and adjusts the structure setting at the 1 back of the chair, consequently in this application, adjust seat 3 and can set up on the positive upper portion of the back of the chair, and can not cause the obstacle to neck pillow 2's regulation to make back of the chair 1 highly can be higher than user's shoulder, play better supporting role in order to relax shoulder muscle to user's shoulder.

Consider back of the chair 1 and neck pillow 2's structure to simplify, reduce the space that occupies, the positive upper portion of back of the chair 1 has inside sunken hidden groove 11, hide groove 11's big or small shape and adjust 3 phase-matchs of seat, adjust seat 3 and inlay and establish in this hidden groove 11, can reduce the thickness of back of the chair 1 and neck pillow 2 two, in addition, neck pillow 2's width and height all are greater than hidden groove 11, neck pillow 2 can cover hidden groove 11 completely, make back of the chair 1 and neck pillow 2 and ordinary chair not have any difference in the outward appearance, improved the senior sense of back of the chair 1 mechanism.

The sliding rail 4 is disposed on the front surface of the adjusting seat 3, and includes two monorail 41 extending up and down and spaced left and right and fixed on the adjusting seat 3, and a rail surface 42 formed between the two monorail 41, and the locking node 4-a is formed on the rail surface 42. The front surface of the adjusting seat 3 can be used as a track surface 42, and a sliding flat plate can be additionally arranged between the two monorail 41 to be used as the track surface 42. The inner side of the monorail 41 is formed with a groove structure extending up and down for cooperation with the sliding connection assembly 5. The left end and the right end of the sliding connection assembly 5 are respectively clamped into the groove structures of the corresponding single rails 41, so that the front position and the rear position of the sliding connection assembly 5 are limited, and the sliding connection assembly 5 is prevented from being separated from the sliding track 4. The back of the slide-on coupling assembly 5 is slidably engaged with the track surface 42 and the locking structure 5-a is formed on the back of the slide-on coupling assembly 5.

Further, the locking node 4-A is formed by the track surface 42 being concave inwards, the locking structure 5-A is formed by the back surface of the sliding connection assembly 5 being convex outwards, and the locking node 4-A and the locking structure 5-A are in snap fit. In this embodiment, the locking node 4-a is a hemispherical recess, the locking structure 5-a is a hemispherical structure, and a recess may be formed on the back of the sliding connection assembly 5 to embed and fix a steel ball therein.

The sliding connection assembly 5 comprises a sliding part 51 and a connecting part 52, wherein the sliding part 51 is in sliding fit with the sliding track 4, two ends of the sliding part 51 are clamped into the corresponding single rails 41, the back surface of a locking structure 5-A is in sliding fit with the track surface 42, the locking structure 5-A is arranged on the back surface of the sliding part 51, the connecting part 52 is detachably connected with the sliding part 51 and is used for fixedly connecting the neck pillow 2, after long-time use, the resistance which is inevitably adjusted when the neck pillow 2 is adjusted can be increased, friction noise can also occur, and therefore the detachable structure is convenient for detaching the connecting part 52 from the sliding part 51, and lubricating oil is dripped on the sliding part 51.

As for the detachable connection manner of the sliding member 51 and the connecting member 52, more specifically, the sliding member 51 has an inwardly recessed snap-fit installation groove 511, the connecting member 52 is snapped into the snap-fit installation groove 511, at least one of the top and the bottom of the sliding member 51 has an opening 512 penetrating up and down into the snap-fit installation groove 511, and the connecting member 52 has a barb structure 521 which can be snapped into the opening 512. When the connecting member 52 is installed in the sliding member 51, the barb structures 521 are pressed so that the connecting member 52 can be inserted into the snap-fit installation groove 511, after the insertion, the barb structures 521 prop against the sliding member 51 and slide inwards along with the connecting member 52 until the barb structures 521 slide to the opening 512, at this time, the barb structures 521 can be snapped on the opening, and the connecting member 52 is fixed with the sliding member 51. When the connecting element 52 needs to be detached, the barb structures 521 are pressed to be completely positioned in the clamping and embedding installation grooves 511, and then the connecting element 52 is pulled outwards.

The edge of inlay card mounting groove 511 has a plurality of guide strips 513 that extend from beginning to end, connecting piece 52 corresponds guide strip 513 department and opens has sliding tray 522, and the cooperation of guide strip 513 and sliding tray 522 has played the guide effect to connecting piece 52, avoids connecting piece 52 to block during the installation.

In addition, in order to improve the smoothness of the sliding link 52 on the sliding rail 4, a plurality of anti-friction strips 514 which extend vertically and are spaced apart from each other in the left-right direction are provided on the back surface of the slider 51, and the rail surface 42 is spaced apart from the back surface of the slider 51, so that the contact area between the slider 51 and the sliding rail 4 is reduced, and the frictional resistance generated when the slider 51 slides vertically is reduced.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments can be modified, or some technical features can be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
