DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To better understand the above technical solution, the following will describe the above technical solution in detail in conjunction with the accompanying drawings of the specification and specific embodiments.

[0022] An embodiment of the utility model discloses a sofa headrest adjustment device. As shown in the attached Figures 1-4 figure, it includes an adjustment plate 1. The adjustment plate 1 is installed on the top of the backrest of a single-person sofa, and a headrest 2 is arranged between two adjustment plates 1;

[0023] An arc-shaped strip 101 is fixedly installed on the outer side of the adjustment plate 1, and an arc-shaped groove 102 penetrating left and right is opened on the adjustment plate 1. A positioning block 103 is slidably connected between the inside of the arc-shaped groove 102 and the arc-shaped strip 101. One end of the positioning block 103 is fixedly connected to the headrest 2, and a rotating bar 104 is fixedly connected below the other end of the positioning block 103. The bottom end of the rotating bar 104 extends outward and is rotatably connected to the outer side of the adjustment plate 1, and the rotating bar 104 is connected with a fixing component.

[0024] During use, first, the fixing component is used to enable the rotating bar 104 to rotate around its bottom end as the axis, so that the positioning block 103 can slide between the inside of the arc-shaped groove 102 and the arc-shaped strip 101, thereby driving the headrest 2 to rotate forward or backward between the two adjustment plates 1 and moving to a suitable position according to the needs of the user. Then, the fixing component is used to fix the position of the rotating bar 104, so that the position of the headrest 2 can be fixed, which is convenient for the headrest 2 to effectively support the neck of the user.

[0025] Furthermore, the headrest 2 includes a pillow core 201 and a pillowcase 202. The pillowcase 202 is sleeved on the outer side of the pillow core 201, and the end of the pillowcase 202 is connected to the outer side of the pillow core 201 through a magic tape.

[0026] The use of the magic tape facilitates the disassembly of the pillowcase 202, and thus facilitates the cleaning of the pillowcase 202.

[0027] Specifically disclosed, the fixing component includes:

[0028] A sleeve 3, the sleeve 3 is fixedly installed on the outer side of the rotating bar 104, and a cavity is opened between the inside of the sleeve 3 and the outer side of the rotating bar 104;

[0029] A positioning rod 302, the positioning rod 302 is movably inserted into the cavity, and a plurality of positioning holes 303 are opened on the outer side of the adjustment plate 1. The end of the positioning rod 302 passes through the rotating bar 104 and is inserted into one of the positioning holes 303.

[0030] Specifically disclosed, a limiting ring 301 is fixedly sleeved on the outer side of the positioning rod 302, a limiting spring 304 is fixedly connected between the side surface of the limiting ring 301 and the inner wall of the cavity, and the limiting spring 304 is movably sleeved on the outer side of the positioning rod 302.

[0031] Furthermore, a plurality of positioning holes 303 are distributed in an arc on the outer side of the adjusting plate 1.

[0032] During the use process, pulling the positioning rod 302 outwards drives the end of the positioning rod 302 to disengage from the positioning hole 303, and makes the limiting ring 301 slide on the inner wall of the cavity, compressing the limiting spring 304. At this time, the rotating bar 104 can rotate until it rotates to a suitable position. At this time, under the action of the elastic force of the limiting spring 304, the limiting ring 301 is pushed to move, and the end of the positioning rod 302 can be inserted into another positioning hole 303, so that the position of the rotating bar 104 can be fixed.

[0033] Furthermore, the other end of the positioning rod 302 passes through the end of the sleeve 3 and extends outwards and is fixedly connected with a pulling block 305.

[0034] By providing the pulling block 305, it is convenient to pull the positioning rod 302.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
