[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: an adjustable telescopic massage cushion, comprising: a massage cushion body 1, an auxiliary headrest 2 disposed on the surface of the massage cushion body 1, a headrest support 3 fixed on the surface of the massage cushion body 1, a telescopic insertion sleeve 5 fixed on the surface of the auxiliary headrest 2, a telescopic insertion rod 4 fixed at the top of the headrest support 3, the telescopic insertion rod 4 being movably inserted into the telescopic insertion sleeve 5, and a limit component being disposed between the telescopic insertion rod 4 and the telescopic insertion sleeve 5.

[0024] In actual use, the adjustable telescopic massage cushion allows users to first release the limiting component, then adjust the height of the telescopic plug sleeve 5 by adjusting the distance the telescopic plug rod 4, which is fixed at the top of the headrest support 3, extends from the telescopic plug sleeve 5. This completes the height adjustment of the auxiliary headrest 2. After adjusting to a comfortable position, the limiting component is restored, and then the massage cushion body 1 is used for massage. This allows the auxiliary headrest 2 to provide sufficient support for the user's head, improving the user's comfort.

[0025] Example 2: Based on Example 1, in order to control the state of the limiting component, the limiting component includes: a limiting groove 6, a limiting rod mounting groove 7, and a limiting rod 8. The limiting groove 6 is formed on the surface of the telescopic plug-in rod 4, and the limiting rod mounting groove 7 is formed on the inner wall of the telescopic plug-in sleeve 5. One end of the limiting rod 8 is movably inserted into the limiting rod mounting groove 7, and the other end of the limiting rod 8 is movably inserted into the limiting groove 6. Several sets of limiting grooves 6 are provided, and the several sets of limiting grooves 6 are linearly distributed on two symmetrical end faces of the telescopic plug-in rod 4. Two sets of limiting rod mounting grooves 7 are provided, and the two sets of limiting rod mounting grooves 7 are respectively set on two symmetrical inner walls of the telescopic plug-in sleeve 5. A support plate 13 is fixed on the surface of the telescopic plug-in sleeve 5.

[0026] When it is necessary to release the limit of the limiting component, the limiting rod 8 is withdrawn from the limiting groove 6 and fully retracted into the limiting rod mounting groove 7, thus releasing the limit of the limiting component. Then, the user holds the tray 13 and adjusts the height of the telescopic plug sleeve 5 by lifting or lowering the tray 13. After adjusting to the appropriate position, the telescopic plug sleeve 5 is further fine-tuned so that the limiting rod mounting groove 7 is aligned with the nearest set of limiting grooves 6. After alignment, one end of the limiting rod 8 automatically extends out of the limiting rod mounting groove 7 and inserts into the limiting groove 6, thus restoring the limiting component to its limiting position.

[0027] Example 3: Based on Example 2, in order to control the extension and retraction of the limit rod 8, a spring 11 is fixed to one end of the limit rod 8 that extends into the limit rod mounting groove 7, and the other end of the spring 11 is fixed to the inner wall of the groove of the limit rod mounting groove 7. A pull rod hole 9 is opened on the surface of the telescopic plug sleeve 5. The pull rod hole 9 is in communication with the limit rod mounting groove 7. A pull rod 10 is movably inserted into the pull rod hole 9. One end of the pull rod 10 extends into the limit rod mounting groove 7 and is fixed to the surface of the limit rod 8. The other end of the pull rod 10 extends out of the pull rod hole 9 and is fixed with a pull ring 12. A support plate 13 is fixed on the surface of the telescopic plug sleeve 5.

[0028] When the limiting rod 8 needs to be fully retracted into the limiting rod mounting groove 7, the user extends one finger from each hand and hooks it into the pull ring 12, pulling the two sets of pull rings 12 in a direction away from each other. The pull rings 12 pull the pull rod 10 out of the pull rod hole 9, and the pull rod hole 9 drives the limiting rod 8 out of the limiting groove 6 and fully retracts into the limiting rod mounting groove 7. At this time, the spring 11 is compressed. Afterwards, while the user's hands are in the pulling position of the pull rings 12, they can conveniently support the tray 13 with their palms. The setting of 3 can prevent the weight of the telescopic plug sleeve 5 from pressing completely on the relatively thin pull rod 10, causing the pull rod 10 to be bent and deformed. After the telescopic plug sleeve 5 is adjusted to the appropriate position, the pull ring 12 is released. The pushing force of the spring 11 on the limit rod 8 makes the limit rod 8 abut against the surface of the telescopic plug rod 4. Then, the height of the telescopic plug sleeve 5 is further fine-tuned. When the limit rod mounting groove 7 is aligned with the nearest set of limit grooves 6, the spring 11 can automatically push one end of the limit rod 8 into the limit groove 6.

[0029] Example 4: Based on Example 3, in order to prevent the auxiliary headrest 2 from being removed from the massage cushion body 1, a slide rail 14 is provided on the surface of the telescopic plug rod 4, and a slider 15 is fixed on the inner wall of the telescopic plug sleeve 5, with the slider 15 slidably connected in the slide rail 14.

[0030] A slide rail 14 is provided on the surface of the telescopic plug-in rod 4, and a slider 15 is fixed on the inner wall of the telescopic plug-in sleeve 5. When the height of the auxiliary headrest 2 is adjusted within the allowable range, the slider 15 is slidably connected in the slide rail 14, which will not affect the extension and retraction of the telescopic plug-in rod 4 and will not affect the height adjustment of the auxiliary headrest 2. When the height of the auxiliary headrest 2 reaches the maximum allowable height, the top of the slider 15 abuts against the top inner wall of the slide rail 14, which can prevent the telescopic plug-in rod 4 from extending further from the telescopic plug-in sleeve 5, thus preventing the auxiliary headrest 2 from being removed from the massage cushion body 1.

[0031] In actual use, this adjustable telescopic massage cushion allows the user to first release the limiting component, then adjust the height of the telescopic plug sleeve 5 by adjusting the distance the telescopic plug rod 4, fixed to the top of the headrest support 3, extends from the telescopic plug sleeve 5. This adjusts the height of the auxiliary headrest 2. After adjusting to a comfortable position, the limiting component is restored, and then the massage cushion body 1 is used for massage. This allows the auxiliary headrest 2 to provide sufficient support for the user's head, improving user comfort. When it is necessary to release the limiting component, the limiting rod 8 is disengaged from the limiting groove 6 and fully retracted into the limiting rod mounting groove 7, thus releasing the limiting component. The user holds the tray 13 and adjusts the height of the telescopic sleeve 5 by lifting or lowering the tray 13. After adjusting to the appropriate position, the user continues to fine-tune the telescopic sleeve 5 so that the limit rod mounting groove 7 is aligned with the nearest set of limit grooves 6. After alignment, one end of the limit rod 8 automatically extends from the limit rod mounting groove 7 and inserts into the limit groove 6, thus restoring the limit component to the limit position. When the limit rod 8 needs to be fully retracted into the limit rod mounting groove 7, the user extends one finger from each hand and hooks it into the pull ring 12, pulling the two sets of pull rings 12 in a direction away from each other. The pull rings 12 pull the pull rod 10 out of the pull rod hole 9, and the pull rod hole 9 drives the limit rod 8 out of the limit position. The spring 11 is compressed as the spring 11 retracts completely into the limiting rod mounting slot 7 after exiting slot 6. While the user's hands maintain the pulling position of the pull ring 12, they can easily support the support plate 13 with their palms. The support plate 13 prevents the weight of the telescopic plug sleeve 5 from pressing entirely on the thinner pull rod 10, thus avoiding bending or deformation. After the telescopic plug sleeve 5 is adjusted to the appropriate position, the pull ring 12 is released. The pushing force of the spring 11 on the limiting rod 8 causes the limiting rod 8 to press against the surface of the telescopic plug rod 4. Then, the height of the telescopic plug sleeve 5 is further fine-tuned. When the limiting rod mounting slot 7 aligns with the nearest set of limiting slots 6, the spring 11 automatically... Push one end of the limiting rod 8 into the limiting groove 6; open a slide rail 14 on the surface of the telescopic plug rod 4, and fix a slider 15 on the inner wall of the telescopic plug sleeve 5. When the height of the auxiliary headrest 2 is adjusted within the allowable range, the slider 15 is slidably connected in the slide rail 14, which will not affect the extension and retraction of the telescopic plug rod 4 and will not affect the height adjustment of the auxiliary headrest 2; when the height of the auxiliary headrest 2 reaches the maximum allowable height, the top of the slider 15 abuts against the top inner wall of the slide rail 14, which can prevent the telescopic plug rod 4 from extending further from the telescopic plug sleeve 5, thus preventing the auxiliary headrest 2 from being removed from the massage cushion body 1.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
