[0019] The present invention will be further described in detail below with reference to the accompanying drawings.
[0020] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively. Specific Implementation Example 1:
[0022] like Figures 1-3 As shown, a reclining bed with front and rear end face angle adjustment function includes a support frame 1. The support frame 1 includes two horizontally arranged crossbars 101 and front support legs 102 and rear support legs 103 at both ends. A connecting frame 2 is fixedly arranged on the surface of the support frame 1. A front movable frame 3 is hinged to the side of the connecting frame 2 facing the front support leg 102. A front ratchet support assembly is arranged between the front movable frame 3 and the support frame 1. A rear movable frame 4 is hinged to the side of the connecting frame 2 facing the rear support leg 103. A rear ratchet support assembly is arranged between the rear movable frame 4 and the support frame 1.
[0023] The angle between the crossbar 101 and the front support leg 102 is greater than 90 degrees and less than 145 degrees, and the angle between the crossbar 101 and the rear support leg 103 is greater than 145 degrees and less than 160 degrees. This provides sufficient support for the reclining bed while ensuring that the rear movable frame 4 has sufficient adjustment angle. During use, the front movable frame 3 can be adjusted upwards via the front ratchet support assembly, and the rear movable frame 4 can be adjusted downwards via the rear ratchet support assembly, thus meeting different user needs.
[0024] The connecting frame 2 includes two connecting rods 201 fixed to the crossbar 101. The front movable frame 3 includes two front movable rods 301 respectively hinged to the ends of the two connecting rods 201. The front ratchet support assembly includes a front hinge rod 5 hinged to the inner side of the front movable rod 301. The ends of the two front hinge rods 5 are fixedly connected to a front support rod 6. The inner side of the two crossbars 101 is provided with a horizontally arranged front support plate 7. The opposing surfaces of the two front support plates 7 are provided with front ratchet grooves that cooperate with the front support rod 6. The front support rod 6 can slide along the front ratchet groove and lock the angle through ratchet engagement.
[0025] By rotating the front movable frame 3 upward and rotating the front hinge rod 5, the two ends of the front support rod 6 are engaged in the corresponding tooth grooves of the front ratchet groove, thereby locking the angle position of the front movable frame and facilitating the adjustment of the angle position of the front movable frame.
[0026] The rear movable frame 4 includes a rear movable rod 401 that is respectively hinged to the other end of the two connecting rods 201. The rear ratchet support assembly includes a rear hinge rod 8 that is hinged to the inner side of the rear movable rod 401. The ends of the two rear hinge rods 8 are fixedly connected to a rear support rod 9. A rear support plate 10 is provided on the inner side of the rear support foot. The opposite surface of the rear support plate 10 is provided with a rear ratchet groove that matches the rear support rod 9. The rear support rod 9 can slide along the rear ratchet groove and lock the angle through ratchet engagement.
[0027] By lifting the rear support rod upwards and engaging its two ends into the corresponding toothed slots, the angle position of the rear movable frame is locked, allowing for convenient adjustment of the rear movable frame's angle position. Specific Implementation Example 2:
[0029] like Figures 4-5 As shown, unlike specific embodiment 1, the rear ratchet support assembly includes a rear hinge rod 8 hinged to the inner side of the rear movable rod 401, a horizontally arranged rear positioning rod 11 fixedly connected between the two rear support legs, a rear positioning plate 12 provided at the bottom of the two rear hinge rods 8, and a rear ratchet groove that cooperates with the rear positioning rod 11 is opened at the bottom of the rear positioning plate 12. The rear positioning rod 11 locks the angle by meshing with different ratchet teeth.
[0030] By rotating the rear hinge rod 8, the rear positioning rod 11 is engaged in the corresponding tooth groove, thereby locking the angle position of the rear movable rod. Alternatively, the rear movable frame 4 can be lifted upwards, and the two rear hinge rods 8 can be rotated to be parallel to the rear movable rod 401. Then, the rear movable frame 4 can be lowered, so that the two rear movable rods 401 are placed on the surface of the rear support foot, further improving its angle adjustment range.
[0031] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
