[0007] As a preferred adjustable bed frame of the utility model, a mounting groove is opened at the lower part of the limiting rod, and a ball is arranged on the inner wall of the mounting groove, and the bottom position of the ball is lower than the bottom position of the limiting rod.

[0008] As a preferred adjustable bed frame of the utility model, a limiting block is fixed on the surface of the guide frame.

[0009] As a preferred adjustable bed frame of the utility model, a guide rod is fixed to the bottom of the second pull plate, and the guide rod passes through the L-shaped plate.

[0010] As a preferred adjustable bed frame of the utility model, a combination groove is opened under the inner wall of the bed cover pad, a nut is fixed to the inner wall of the combination groove, a combination hole is opened at the bottom of the combination plate, a fastening bolt is arranged inside the combination hole, and the fastening bolt is threadedly connected with the nut.

[0011] As a preferred adjustable bed frame of the utility model, a limiting plate is fixed on the surface of the sliding rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model discloses that after the massage is finished, when the bed cover pad needs to be located in the through groove, the first pulling plate is pulled, so that the first pulling plate drives the pulling rod and the movable plate to move toward the right side plate. At this time, the compression spring can be compressed, and the movable plate can make the linkage plate gradually rotate upward during the movement, so that the linkage plate can lift up the combined plate and the bed cover pad, so that the bed cover pad can enter the through groove. When the bed cover pad moves to the top and is parallel to the top of the mattress, the pulling rod will move to the limit groove to face the lower part of the limit rod. At this time, the stretching spring will release its own elastic potential energy, so that the limit rod can enter the limit groove, so that the pulling rod can The rod can achieve a positioning effect, so that the bed cover pad will not fall down by itself when the user is lying flat. When the through slot needs to be in an open state, the second pull plate is pulled upwards to stretch the tension spring and disengage the limiting rod from the limiting slot. At this time, the compression spring will rebound, so that the movable plate moves toward the left side plate, thereby driving the linkage plate to rotate downward through the movable plate, so that the bed cover pad can move downward. Through the above design, the bed cover pad and the through slot can be quickly installed and removed, which makes it more convenient for users to use and there is no need to store the bed cover pad separately, thereby improving the practicality of the device.

[0021] See also Figure 1-6 An adjustable bed frame comprises a bed frame body 1, a mattress 2 is arranged on the surface of the bed frame body 1, the mattress 2 is composed of an adjustable head and a mattress body, a through groove 3 is opened on the surface of the mattress 2, and a bed cover 4 is arranged inside the through groove 3;

[0022] The bed frame body 1 is used to support the mattress 2, the through groove 3 is used to place the bed cover pad 4, and the adjustable headboard is used to support and adjust the angle of the user's head.

[0023] Two side panels 5 are fixed on the surface of the bed frame body 1, two sliding rods 6 are fixed on the surface of the side panels 5, and a movable panel 7 is slidably connected on the surface of the sliding rod 6. Two linkage panels 8 are hinged on the top of the movable panel 7, and a combination panel 9 is hinged on the top of the linkage panel 8. The top of the combination panel 9 is detachably connected to the bottom of the bed cover pad 4. A pull rod 12 is fixed on the surface of the movable panel 7, and the pull rod 12 passes through the right side panel 5 and is fixed with a first pull panel 13. A guide frame 10 is fixed on the surface of the bed frame body 1, and the combination panel 9 is slidably connected to the surface of the guide frame 10. A compression spring 14 is fixed on the surface of the movable panel 7, and one end of the compression spring 14 is fixedly connected to the surface of the right side panel 5. An L-shaped panel 15 is fixed on the top of the right side panel 5, and the surface of the L-shaped panel 15 slides through the limiting rod 16. A limiting groove 17 is provided on the surface of the pull rod 12, and a tension spring 18 is fixed on the top of the L-shaped panel 15, and a second pull panel 19 is fixed on the top of the tension spring 18;

[0024] When the massage is finished and the bed cover pad 4 needs to be located inside the through groove 3, the first pull plate 13 is pulled, so that the first pull plate 13 drives the pull rod 12 and the movable plate 7 to move toward the right side plate 5. At this time, the compression spring 14 can be compressed, and the movable plate 7 can cause the linkage plate 8 to gradually rotate upward during the movement, so that the linkage plate 8 can lift the combined plate 9 and the bed cover pad 4, so that the bed cover pad 4 can enter the through groove 3. When the bed cover pad 4 moves to the top and is parallel to the top of the mattress 2, the pull rod 12 will move to the limit groove 17 to face the bottom of the limit rod 16. At this time, the tension spring 18 will release its own elastic potential energy, so that the limit rod 16 can enter the limit groove 17, The pull rod 12 can achieve a positioning effect, so that the bed cover pad 4 will not fall down by itself when the user is lying flat. When the through slot 3 needs to be in an open state, the second pull plate 19 is pulled upward to stretch the tension spring 18 and disengage the limiting rod 16 from the limiting slot 17. At this time, the compression spring 14 will rebound, so that the movable plate 7 moves toward the left side plate 5, thereby driving the linkage plate 8 to rotate downward through the movable plate 7, so that the bed cover pad 4 can move downward. Through the above design, the bed cover pad 4 and the through slot 3 can be quickly installed and removed, which makes it more convenient for users to use it and there is no need to store the bed cover pad 4 separately, thereby improving the practicality of the device.

[0025] Furthermore, a mounting groove is provided at the lower part of the limiting rod 16, and a ball 21 is provided on the inner wall of the mounting groove, and the bottom position of the ball 21 is lower than the bottom position of the limiting rod 16;

[0026] When the pull rod 12 is moving, the ball 21 can contact the surface of the pull rod 12 and can also rotate, thereby reducing friction and avoiding the short service life of the limit rod 16 caused by direct friction between the bottom of the limit rod 16 and the surface of the pull rod 12.

[0027] Furthermore, a limiting block 11 is fixed on the surface of the guide frame 10;

[0028] The limiting block 11 can limit the lowest position of the combined plate 9, thereby limiting the rotation angle of the linkage plate 8, and preventing the linkage plate 8 from getting stuck due to a small rotation angle.

[0029] Furthermore, a guide rod 20 is fixed at the bottom of the second pull plate 19, and the guide rod 20 passes through the L-shaped plate 15;

[0030] The setting of the guide rod 20 enables the limiting rod 16 to obtain a guiding effect when it moves, thereby preventing the limiting rod 16 from being offset.

[0031] Furthermore, a combination groove is provided below the inner wall of the bed cover pad 4, a nut 23 is fixed to the inner wall of the combination groove, a combination hole is provided at the bottom of the combination plate 9, a fastening bolt 22 is provided inside the combination hole, and the fastening bolt 22 is threadedly connected to the nut 23;

[0032] The fastening bolt 22 can be twisted out from the nut 23 by rotating it, so that the bed cover mat 4 and the combination plate 9 can be disassembled, making it more convenient to clean the bed cover mat 4.

[0033] Furthermore, a limit plate 24 is fixed on the surface of the slide bar 6;

[0034] The limiting plate 24 can limit the maximum moving position of the movable plate 7 to prevent the bed cover pad 4 from being lifted to the top higher than the mattress 2.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
