DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 The present application is further described in detail. This device can be used by people of different heights.

[0020] The present application embodiment discloses an adjustable accompanying folding bed. Figure 1 and Figure 2, an adjustable accompanying folding bed, comprising two frame-shaped first bed frames 1, the opposite side surfaces of the two first bed frames 1 are rotatably connected with a frame-shaped second bed frame 2, and the two first bed frames 1 are rotatably connected to each other, mattresses 6 are placed on the upper surfaces of the two first bed frames 1 and the two second bed frames 2, and rod-shaped first support rods 3 are rotatably connected to the side surfaces of the two first bed frames 1, and rod-shaped second support rods 4 are rotatably connected to the side surfaces of the two second bed frames 2, and the first support rods 3 and the second support rods 4 are rotatably connected to each other, and the lower surfaces of a plurality of first support rods 3 and a plurality of second support rods 4 are rollingly connected with fixed rollers 10, and the side surfaces of the two first support rods 3 on both side surfaces of the first bed frame 1 are fixedly connected with rod-shaped connecting rods 9, so that when the device is not needed, the accompanying person pulls down the first guardrail 5 with both hands, thereby driving the first bed frame 1 and the second bed frame 2 to rotate relative to each other, and at the same time, uses the feet to The connecting rod 9 is pushed inward to drive the first support rod 3 and the second support rod 4 to rotate relative to each other. After the first bed frame 1 and the second bed frame 2 are rotated close to a certain distance, the fixing component of the fixing roller 10 is stepped on to fix the fixing roller 10, so that the device can be stably folded for easy storage. Secondly, the two side surfaces of the two second bed frames 2 are fixedly connected with a U-shaped plate-like first guardrail 5, so that the accompanying person can be protected by the first guardrail 5 to prevent the accompanying person from accidentally falling off the bed when sleeping, and the side surface of the second bed frame 2 is connected with a U-shaped rod-shaped third bed frame 7, so that when people of different heights use the device, the third bed frame 7 can be pulled outward for a certain distance and fixed by being fixed, so that it can be suitable for accompanying persons of different heights, thereby improving the versatility and practicality of the device, and the upper surface of the third bed frame 7 is fixedly connected with a U-shaped plate-shaped second guardrail 8, so that the accompanying person who is sleeping can be protected by the second guardrail 8.

[0021] Reference Figure 2 A groove-shaped slide groove 11 is opened on the side surface of the second bed frame 2, and the third bed frame 7 slides relative to the inner wall of the slide groove 11, so that when people of different heights use it, the third bed frame 7 can slide on the inner wall of the slide groove 11, thereby facilitating the change of the length of the device to meet the usage needs of people of different heights, thereby improving the versatility of the device.

[0022] Reference Figure 3A plurality of arc-shaped grooves 12 are provided on the side surface of the third bed frame 7, and a groove-shaped limiting groove 13 is provided on the side surface of the second bed frame 2. The inner wall of the limiting groove 13 is elastically slidably connected with a block-shaped limiting block 14 through a spring, and the limiting block 14 can be engaged with the inner wall of any groove 12, so that when adjusting the use length of the device, the limiting block 14 is first pressed to shrink it to the inner wall of the limiting block 14. At this time, the spring is in a compressed state, and then the third bed frame 7 is slid on the inner wall of the slide groove 11, so as to adjust the sliding distance of the third bed frame 7. Then, after the external force disappears, the limiting block 14 rebounds and engages with the inner wall of the corresponding groove 12 under the resetting action of the spring, thereby completing the rapid adjustment of the length of the device.

[0023] The implementation principle of an adjustable accompanying folding bed in the embodiment of the present application is as follows: when the device is needed, the accompanying person lifts the fixing part of the fixable roller 10 upwards by foot, so that the fixable roller 10 can roll, and then presses the first bed frame 1 and the second bed frame 2 downward by hand, and at the same time drives the first support rod 3 and the second support rod 4 to rotate relative to each other, and the fixable roller 10 is in a rolling state. After the first bed frame 1 and the second bed frame 2 are in a horizontal state, the device is unfolded, and then according to the different heights of the accompanying person, the limit block 14 is first pressed to shrink to the inner wall of the limit block 14, and the spring is in a compressed state at this time, and then the third bed frame 7 is slid outward on the inner wall of the slide groove 11 for a certain distance, so as to adjust the sliding distance of the third bed frame 7, and then after the external force disappears, the limit block 14 rebounds and engages with the inner wall of the corresponding groove 12 under the resetting action of the spring, thereby completing the rapid adjustment of the length of the device, so that it can be suitable for accompanying persons of different heights, thereby improving the versatility and practicality of the device.
