Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1 to 5, the present invention discloses a folding structure for a bed, the bed includes a bed frame 100 and bed legs 200, and the bed legs 200 rotate relative to the bed frame 100 to unfold or fold the bed, including:

a first rotating member 300 connected to the bed frame 100 and having a rotating portion 320; the joint of the side surface and the end surface of the first rotating member 300 is recessed inwards to form a locking notch 310, and the locking notch 310 is located on one side of the first rotating member 300 away from the rotating part 320;

a second rotating member 400 connected to the bed leg 200, the second rotating member 400 being rotatably connected to the rotating portion 320;

the driving member 500 is slidably connected to the second rotating member 400, a locking member 510 is disposed on the driving member 500, the driving member 500 is slid to enable the locking member 510 to enter or exit the locking notch 310, and the locking member 510 enters or exits the locking notch 310 to lock or release the rotation between the first rotating member 300 and the second rotating member 400.

In this application, the first rotating member 300 is connected to the bed frame 100, the second rotating member 400 is connected to the bed leg 200, and the bed frame 100 and the bed leg 200 can rotate by the relative rotation of the first rotating member 300 and the second rotating member 400, so as to fold and unfold the bed. When the foldable bicycle is folded and unfolded, only the driving member 500 needs to be slid to enable the locking member 510 to enter or exit the locking notch 310, so that the folding and unfolding steps are simplified, and the operation difficulty is reduced.

Specifically, when the locking member 510 enters the locking notch 310, if the bed leg 200 tends to rotate, the locking member 510 will abut against the inner wall of the locking notch 310, and the bed leg 200 will be prevented from rotating, so as to maintain the bed in the unfolded state; when the locking member 510 is withdrawn from the locking notch 310, the locking member 510 cannot abut against the inner wall of the locking notch 310, and the locking member 510 rotates along with the bed leg 200, so that the bed frame 100 and the bed leg 200 can be folded.

Meanwhile, since the rotation portion 320 and the locking notch 310 are respectively located at both sides of the end surface of the first rotation member 300, the length between the rotation portion 320 and the locking notch 310 is increased. When the bed is unfolded, the locking piece 510 abuts against the inner wall of the locking notch 310 and is stressed together with the rotating part 320, according to the lever principle, the stress point of the locking piece 510 comprises the rotating part 320, the abutting position of the locking piece 510 and the locking notch 310 and the contact position of the bed leg 200 and the ground, the part from the rotating part 320 to the abutting position of the locking piece 510 and the locking notch 310 is used as one lever, the part from the abutting position of the locking piece 510 and the locking notch 310 to the contact position of the bed leg 200 and the ground is used as the other lever, and the two levers bear the weight of the whole bed. From the foregoing, the length between the rotating portion 320 and the locking notch 310 is increased, which is equivalent to the length of the lever formed by the portion, so that the stress of the rotating portion 320 is reduced, and therefore, the connection strength of the whole bed when the whole bed is unfolded can be enhanced.

Further, two first rotating members 300 are disposed on the bed frame 100, a second rotating member 400 is disposed on the bed leg 200, and two ends of the second rotating member 400 are rotatably connected to one of the first rotating members 300, respectively.

The two ends of the second rotating part 400 are respectively provided with the first rotating part 300, and the two locking studs are arranged on the driving part 500, so that the second rotating part 400 and the two first rotating parts 300 are controlled to unlock and lock by sliding the driving part 500, and the operation difficulty is reduced while the connection strength is improved.

Further, a limit groove 410 is formed on the second rotating member 400, one end of the locking section passes through the limit groove 410 and enters the locking notch 310, and the locking section slides in the limit groove 410 to enable the locking section to exit the locking notch 310.

The limiting groove 410 is formed, so that when the bed is unfolded, the locking piece 510 is abutted to the inner wall of the locking notch 310 and the inner wall of the limiting groove 410, the second rotating piece 400 and the first rotating piece 300 are stressed together, and the stability in the unfolded state is improved.

Further, two ends of the driving member 500 are respectively provided with a first limiting portion 520, and two ends of the second rotating member 400 are respectively provided with a second limiting portion 331;

when the locking member 510 enters the locking notch 310, the first limiting part 520 is separated from the second limiting part 331; when the locking member 510 exits the locking notch 310, the first limiting portion 520 abuts against the second limiting portion 331 to limit the driving member 500 to slide continuously.

Specifically, during unlocking, the driving member 500 is pressed downward, so that the first limiting portion 520 and the locking stud move downward at the same time, when the first limiting portion 520 moves downward to abut against the second limiting portion 331, the locking stud just moves downward to exit the locking notch 310, and at this time, the bed leg 200 can be rotated to fold.

In the folding process, the arrangement of the first limiting part 520 and the second limiting part 331 plays a limiting role, so that the driving part 500 is prevented from excessively sliding downwards to crush the spring 420 and other parts; meanwhile, the indication function can be achieved, when the driving part 500 is pressed to the two limiting parts to abut against each other, the locking stud is shown to exit the locking notch 310 at the moment, the bed leg 200 and the bed frame 100 are unlocked through rotation, the situation that whether unlocking is achieved cannot be judged by an operator is avoided, and the operation difficulty is reduced.

Further, the first position-limiting portion 520 protrudes from the end surface of the driving member 500.

Further, the portable terminal further comprises a rotating screw 330, one end of the rotating screw 330 sequentially penetrates through the first rotating member 300 and the second rotating member 400, a nut is connected to a part of the rotating screw 330 extending out of the second rotating member 400 through a thread, and the second limiting portion 331 comprises the nut.
