DETAILED DESCRIPTION

Embodiment 1:

As shown in the figures, a baby folding bed includes a bed frame 1 with an open position and a folded position, and a locking mechanism 2 for locking the bed frame 1 in the open position. The bed frame 1 includes side brackets 11 located on the left and right sides, and a plurality of cross braces fixedly connected between the side brackets. The plurality of cross braces make the side brackets on both sides rigidly connected and cannot be folded horizontally.

The side bracket 11 on each side includes

A surrounding rod frame 111, the surrounding rod frame 111 comprises a surrounding rod body 111a, a sliding seat 111b fixed to the front of the surrounding rod body 111a, and a fixing seat fixed to the rear of the surrounding rod body 111a, wherein the sliding seat 111b is provided with a guide channel;

A front support frame 112, the upper portion of which is pivotally connected to the sliding seat 111b around the first axis X1;

A rear support frame 113, the upper portion of which is pivotally connected to a fixing seat around a second axis X2;

The linkage rod 114, the front part of the linkage rod 114 is pivotally connected with the front support frame 112 around the third axis X3, and the rear part of the linkage rod 114 is pivotally connected with the rear support frame 113 around the fourth axis X4. The surrounding rod frame 111, the front support frame 112, the rear support frame 113, and the linkage rod 114 form a four-bar linkage. When the front support frame 112 rotates around the first axis X1 and folds toward the middle of the surrounding rod frame 111, the third axis X3 moves clockwise around the first axis X1, so that under the action of the linkage rod 114, the fourth axis X4 is pulled to move counterclockwise around the second axis X2, causing the rear support frame 113 to rotate around the second axis X2 and also fold toward the middle of the surrounding rod frame 111.

The front ends of the surrounding rod frames 111 on both sides, the rear ends of the surrounding rod frames 111, the front support frames 112, and the rear support frames 113 are fixedly connected into one body through transverse support rods.

In this embodiment, the third axis X3 is located above the first axis X1, and the fourth axis X4 is located below the second axis X2. When the bed frame 1 is in the open position, the line connecting the axis centers of the first axis X1 and the second axis X2 intersects with the line connecting the axis centers of the third axis X3 and the fourth axis X4. The locking mechanism can be set at multiple positions. For example, locking any one of the first axis X1, the second axis X2, the third axis X3, and the fourth axis X4 can achieve locking of the entire bed frame. The position setting of the above axis points enables the linkage rod 114 to be slidably set on the surrounding rod frame 111, and by locking the relative positions of the two, the surrounding rod frame has multiple positions of different heights.

In this embodiment, the linkage rod 114 is slidably disposed on the surrounding rod frame 111, and the locking mechanism 2 is disposed between the linkage rod 114 and the surrounding rod frame 111. The locking mechanism 2 has a locking state capable of locking the linkage rod 114 in more than two positions relative to the surrounding rod frame 111, thereby locking the bed frame 1 in two opening positions of different heights.

The linkage rod 114 is slidably arranged with the sliding seat 111b, and the linkage rod 114 can be slidably inserted into the guide channel. The locking mechanism 2 is arranged between the sliding seat 111b and the linkage rod 114. The specific structure of the locking mechanism is not the design key point of the present invention. As long as the structure can lock the positions of the two sliding parts relative to each other, it can be applied. For example, two lock holes are provided on the linkage rod along its length direction, and a movable lock tongue is provided on the sliding seat to be inserted and matched with the lock holes. When the movable lock tongue is inserted into the corresponding lock hole, the positions of the two sides are locked accordingly. In order to facilitate the simultaneous control of the locking mechanism of the side brackets on both sides with one hand, an unlocking control mechanism 3 for controlling the locking mechanism 2 is provided on the cross brace between the front ends of the surrounding rod frame 111 or the cross brace between the rear ends of the surrounding rod frame 111. The unlocking control mechanism is connected to the movable lock tongue by a traction rope. There are many detailed structures of the unlocking control mechanism, which are not the design key points of the present invention and are not repeated here.

The baby folding bed has a high position mode and a low position mode in the open position.

When the baby folding bed is in the high-position mode, as shown in FIGS. 1 and 3 , the front support frame and the rear support frame are opened to the limit position in an “eight” shape and locked by the locking mechanism.

When the crib is switched from a high-position mode to a low-position mode, it is first unlocked by the unlocking control mechanism, and then the front support frame 112 is rotated around the first axis X1 and moved toward the middle of the surrounding rod frame 111, and the third axis X3 moves clockwise around the first axis X1, so that under the action of the linkage rod 114, the fourth axis X4 is pulled to move counterclockwise around the second axis X2, causing the rear support frame 113 to rotate around the second axis X2 and also move toward the middle of the surrounding rod frame 111, and the front support frame and the rear support frame intersect in an "X" shape. The height of the surrounding rod frame is lowered by adjusting the crossing angle of the "X" shape, and locked again by the locking mechanism to reach the low-position mode. The distance between the rear supports on both sides is smaller than the distance between the front supports on both sides, so that the rear support frame can pass through between the front supports on both sides.

During the transition from high mode to low mode, the boom frame remains in a flat position.

Unlock it again, press down the surrounding frame through the unlocking control mechanism, and continue to adjust the "X"-shaped crossing angle until the surrounding frame, front support frame and rear support frame are tightly together. In this way, the baby folding bed is folded. The folded baby bed is flat, with a small structure and is easy to carry and store.

In this embodiment, the cross brace between the front support frames 112 on both sides and the cross brace between the rear support frames 113 on both sides are respectively located at the lower end and are arc-shaped rocking arms 12 arched downward, and anti-rocking members 112a are movably provided on the lower end of the front support frame 112 and the lower end of the rear support frame 113. When the anti-rocking members are bent upward and separated from the ground, the baby folding bed can be used as a rocking bed.

Embodiment 2:

Although not shown in the figure, the difference between the second embodiment and the first embodiment is that the front ends of the surrounding rod frames 111 on both sides, the rear ends of the surrounding rod frames 111, the front support frames 112, and the rear support frames 113 are respectively connected by folding rods, so that when the bed frame is folded to a flat state, it can be further folded horizontally to reduce the volume, and an unlocking control mechanism 3 for controlling the locking mechanism 2 is provided on the folding rod between the front ends of the surrounding rod frames 111 or the folding rod between the rear ends of the surrounding rod frames 111.

The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
