[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Reference Figure 1-3A headrest guide sleeve with a fixed structure includes a U-shaped fork 3, a headrest guide plate 4, and a headrest guide rod 5. The headrest guide rod 5 is symmetrically fixed at the bottom of the U-shaped fork 3, and the headrest guide rod 5 is movably inserted into the car seat. A mounting frame 1 is fixed at the middle position at the bottom of the headrest guide plate 4. A stepped cover 2 is fixed to the side of the mounting frame 1 with bolts. The stepped cover 2 includes a wide section and a narrow section. The narrow section of the stepped cover 2 has the same cross-sectional size as the inner cavity of the mounting frame 1. When the narrow section of the stepped cover 2 is inserted into the interior of the mounting frame 1, the mounting bolts at the four corners of the stepped cover 2 can be quickly positioned.
[0020] Step columns 7 are movably inserted into the two side surfaces of the mounting frame 1. A limiting tooth groove 71 is provided at the head of the step column 7. The other end of the step column 7 is movably inserted into the side surface of the head of the U-shaped fork 3. Holes are reserved on both side surfaces of the mounting frame 1 for installing the step columns 7. The tail of the step column 7 is inserted into the reserved holes, and the head of the step column 7 is placed inside the mounting frame 1.
[0021] An adjustment component for adjusting the angle between the headrest and the car seat is provided inside the mounting frame 1. An arc-shaped groove 41 is provided at the midline position of the bottom surface of the headrest guide plate 4. An avoidance groove 42 is vertically provided at the end of the arc-shaped groove 41. A stepped hole is provided on the front side of the U-shaped fork 3. A fixing bolt 31 is screwed into the thread of the stepped hole of the U-shaped fork 3. When the fixing bolt 31 is fully screwed into the stepped hole, the head of the fixing bolt 31 is flush with the side surface of the U-shaped fork 3.
[0022] A mounting hole 12 is provided on the side of the stepped column 7, and the tail of the fixing bolt 31 is inserted into the mounting hole 12. The adjustment assembly includes a center column 9, a common rod 8, and a limiting cone rod 6. A center column 9 is fixedly provided in the middle position of the common rod 8, and the other end of the center column 9 is movably inserted into the mounting frame 1. The outer wall of the center column 9 is fixedly connected to one end of the connecting spring 11, and the other end of the connecting spring 11 is fixedly connected to the side of the inner cavity of the mounting frame 1. The other end of the center column 9 is fixedly provided with a lifting handle 10 after passing through the stepped cover 2. By pulling the lifting handle 10 outward, the two sets of limiting cone rods 6 can be driven to be inserted into the limiting tooth groove 71 at the same time.
[0023] The two ends of the common rod 8 are vertically fixed with limiting cone rods 6 . The cross-sectional shape of the head of the limiting cone rod 6 is trapezoidal, and the width of the head of the limiting cone rod 6 is the same as the width of the head of the limiting tooth groove 71 .
[0024] The specific implementation steps and principles of this utility model are as follows:
[0025] Take adjusting the inclination angle of the headrest guide sleeve as an example. When the lifting handle 10 is not subjected to external force, the connecting spring 11 is in its original length state. At this time, the limiting cone rod 6 is inserted into the limiting tooth groove 71, and the headrest guide plate 4 cannot rotate around the U-shaped fork 3. According to actual user needs, the lifting handle 10 is pulled externally by manpower, and the lifting handle 10 drives the limiting cone rods 6 at both ends of the common rod 8 to disengage from the limiting tooth groove 71, and the headrest guide plate 4 is rotated to an appropriate angle. The lifting handle 10 is released, and the connecting spring 11 drives the limiting cone rod 6 to be inserted into the limiting tooth groove 71 again, thereby limiting the headrest guide plate 4 to a specific angle.
[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
