As shown in
The upper frame extending stand 2 includes an upper frame extending rod 21, and an upper frame extending sliding rod I 22 and an upper frame extending sliding rod II 23 respectively fixed on the upper frame extending rod 21. The upper frame extending sliding rod I 22 is sleeved in the upper frame cross rod I 12, and can move along the sliding chute in the upper frame cross rod I 12. The upper frame extending sliding rod II 23 is sleeved in the upper frame cross rod II 13, and can move along the sliding chute in the upper frame cross rod II 13.
The bottom bed frame 3 includes a bottom frame rod and a bottom frame crossarm 31 with one end connected to the bottom frame rod. The bottom frame crossarm 31 is “I”-shaped and is composed of three rods: a bottom frame cross rod I 32, a bottom frame cross rod II 33 and a bottom frame cross rod III 34. The bottom frame cross rod I 32 and the bottom frame cross rod II 33 are spaced apart, and have one end fixed on the bottom frame rod. The bottom frame cross rod III 34 is fixed between the bottom frame cross rod I 32 and the bottom frame cross rod II 33. Sliding chutes are respectively formed in the bottom frame cross rod I 32 and the bottom frame cross rod II 33.
The bottom frame extending stand 4 includes a bottom frame extending rod 41, and a bottom frame extending sliding rod I 42 and a bottom frame extending sliding rod II 43 respectively fixed on the bottom frame extending rod 41. The bottom frame extending sliding rod I 42 is sleeved in the sliding chute of the bottom frame cross rod I 32 and can move along the sliding chute. The bottom frame extending sliding rod II 43 is sleeved in the sliding chute of the bottom frame cross rod II 33 and can move along the sliding chute.
Rotating pins 5 are respectively arranged at end portions of the upper frame rod 11 and the upper frame extending rod 21. Pipe sleeves 6 are respectively arranged at end portions of the bottom frame rod and the bottom frame extending rod 41. The rotating pins 5 and the pipe sleeves 6 are connected with each other and are respectively hinged with the upper frame rod 11 and the bottom frame rod. The upper frame extending rod 21 is hinged with the bottom frame extending rod 41.
The linear actuating device 7 is mounted between the upper bed frame 1 and the bottom bed frame 3, and can unfold or fold the upper bed frame 1 and the bottom bed frame 3. The linear actuating device 7 includes a linear actuator 71 and a support arm 72 with one end hinged to the upper bed frame 1. The other end of the support arm 72 is provided with a guide wheel 73. The guide wheel 73 resists against the bottom frame cross rod III 34. The upper frame cross rod I 12 is provided with a connecting seat 8. The connecting seat 8 is provided with a pin shaft. The pin shaft is hinged with a hinge arm 74, a shaft sleeve 75 and the support arm 72. One end of the linear actuator 71 is connected with the upper frame cross rod I 12 through the hinge arm 74, and the other end is fixed to the bottom bed frame 3. The linear actuator 71 drives the upper bed frame 1 to rise up by means of the guide wheel 73.
This bed frame is adjustable in width, and is provided with a limiting structure for maximum and minimum stretching dimensions. In the limiting structure, the upper frame extending sliding rod I 22 is provided with several width stop holes; and indicator pins 16 plugged into the width stop holes to limit a stretching width of the bed frame are mounted on the upper frame crossarm. After the width is adjusted, the width is locked by handle screws of the upper frame cross rod I 12 and the bottom frame cross rod I 32.
This product can be wirelessly remotely controlled. The bottom frame cross rod I 32 is provided with a wireless control box which controls the linear actuator 71 to work through a signal.
The bottom bed frame 3 is provided with a fixing member 9. The fixing member 9 is a sliding chute strap iron. The upper bed frame 1 is provided with a mattress limiting stop rod 10. The mattress limiting stop rod 10 cooperates with the sliding chute strap iron to fix the whole bed frame on a bed surface.
The specific embodiment is only an explanation of the present disclosure, and it is not a limitation to the present disclosure. After reading this specification, those skilled in the art can make modifications to this embodiment that do not create any contribution as needed, but the modifications shall be protected by the patent law within the scope of the claims of the present disclosure.
