Description

BACKGROUND

Technical Field

The present invention relates to the field of bed frame structures, and in particular, to a novel detachable bed frame assembly mechanism.

Related Art

Common bed frames are bulky, costly in packaging and transportation, and inconvenient to be moved into a house. Bed frames that can be easily disassembled for transportation are also present on the market, which, however, generally have a poor load-bearing capability. In addition, most current detachable beds are opened under a boosting force of a pneumatic rod having a large force value, which almost has no boosting force at the beginning as a result of an excessively small angle but may directly bounce as the boosting force increases with an increase in the angle, causing a hidden hazard of injuring people. During closing, as the angle becomes smaller, the boosting force is increasingly smaller and a closing speed is increasingly larger, directly causing fingers to be squeezed. Even after the pneumatic rod slowly fails, other serious safety hazards such as sudden falling of an upper cover, or the like are caused.

Embodiment 2

As shown in FIG. 6 to FIG. 7, a novel detachable bed frame assembly mechanism includes a bed frame body. The bed frame body includes an outer frame, an inner frame, and two sets of wooden strips.

The outer frame is a rectangular frame including two door-shaped horizontal tubes 8, two lateral tubes, steel channels 9, bolts, and nuts. One end of each of the steel channels is disposed within a port of a lateral end of each of the two door-shaped horizontal tubes, and the other end of the two steel channels is disposed within each of the two lateral tubes and is fixedly connected to the lateral tube through the bolts and the nuts.

The inner frame includes at least one horizontal connecting tube, iron sheets, bolts, and nuts. The horizontal connecting tube is connected between the two lateral tubes and is parallel to the horizontal tubes, and the horizontal connecting tube is connected to the lateral tubes at both ends of the horizontal connecting tube through the iron sheets and is fixed through the bolts and the nuts.

The two sets of wooden strips are symmetrically disposed on the horizontal connecting tube and the horizontal tubes on both sides of the horizontal connecting tube and are parallel to the lateral tubes, to connect the horizontal connecting tube to the horizontal tubes.

The utility model adopts the L-shaped iron plate or the steel channel to connect the tubes, so that the connection is convenient and tight and the operation is simple. Operations of such parts are very simple for purchasers, an overall size after the connection is well controlled, and the simple design embodies simplicity and aesthetics of the product.

The parts are fixed and positioned through interlocking by using the bolts, which is simple to operate. In addition, overall strength is increased through iron connection, which is more effective than an ordinary strengthening way (enlargement, thickening, or the like of tubes), and a longitudinal load-bearing capability of the product is significantly increased after addition of the sheet metal.

Embodiment 3

As shown in FIG. 11 to FIG. 19, the flip link mechanism includes: a box mounting plate 101, an upper cover mounting plate 102, a first link 103, a second link 104, a pneumatic rod 105 having a low force value, a sliding link 106, a positioning slider 107, a booster tension spring 108, and a bump 106-1.

One end of the box mounting plate 101 is connected to one end of the first link 103 through the booster tension spring 108, the other end of the box mounting plate 101 is connected to one end of the second link 104, and the other end of the first link 103 is connected to one end of the upper cover mounting plate 102. One end of the sliding link 106 is connected in the middle of the second link 104, the other end of the sliding link 106 is connected in the middle of the upper cover mounting plate 102, the positioning slider 107 is slidable reciprocally in the sliding link 106 along a guide bar 106-2 and is rotatable by means of the bump 106-1 below a sliding chute on the sliding link 106. The other end of the second link 104 is connected to the upper cover mounting plate 102 and is located between the first link 103 and the sliding link 106, one end of the pneumatic rod 105 is connected to the other end of the upper cover mounting plate 102, and the other end of the pneumatic rod 105 is located at a lower part of the sliding link 106 and is connected in the middle of the second link 104.

The upper cover mounting plate 102 is provided with mounting holes, the bed frame body is also provided with mounting holes, and the mounting holes of the upper cover mounting plate 102 and the bed frame body are aligned with each other, a bolt-nut assembly is successively passed through the mounting holes of the upper cover mounting plate 102 and the bed frame body and is fastened, so that the bed frame body is connected and fixed with the flip link mechanism.

A movement principle of a link mechanism is as follows.

The box mounting plate 101 is fixed under a box 109 (at a storage position), and the upper cover mounting plate 102 is fixed to an upper cover 1010. When the upper cover is lifted, the link mechanism is slowly opened to a limiting opened state under the action of the booster tension spring, and the positioning slider and the sliding link also reach a limit state. Then the upper cover is pulled down, so that the positioning slider 107 is rotated by a specific angle under the action of the bump 106-1 on the sliding link 106. When the upper cover is pulled down again, the positioning slider and the sliding link are locked to prevent the upper cover from falling when the pneumatic rod 105 fails, and when the link mechanism is lifted to the limiting opened state again, the positioning slider falls. At this point, if the upper cover is pressed down again, the locked state is released. The upper cover may be pressed down, and when the upper cover is about to reach a closed state, the booster tension spring 108 between the box mounting plate 101 and the first link 102 provides a boosting force to prevent fingers from being injured by sudden falling and closing.

Due to an excessively large angle of the pneumatic rod during closing, a vertical upward force that is provided is relatively small, but increasing the force value of the pneumatic rod causes the upper cover to bounce excessively fast during lifting. Therefore, in this application, the booster tension spring 108 is added at the end, so that a boosting force can be provided in the folded state without needing to increase the force value of the pneumatic rod 105 to eliminate the safety hazard of injuring people when the upper cover bounces.

The booster tension spring 108 at the end provides a boosting force during initial lifting of the upper cover to facilitate the lifting of the upper cover, and provides the boosting force when the upper cover is to be folded and closed to eliminate the safety hazards of squeezing fingers.

The sliding link 106 and the positioning slider 107 form a self-locking mechanism. When the upper cover is opened to the limiting position and pressed down again, the self-locking mechanism locks the upper cover, so that the upper cover does not fall again. When the upper cover is lifted and then pulled down, the self-locking is released and the upper cover can be folded and closed. The self-locking mechanism can eliminate the safety hazard of sudden falling of the upper cover when the pneumatic rod fails in the opened state.

The pneumatic rod 105, the second link 104, and the upper cover mounting plate 102 form a triangular structure, which is more stable during opening and closing of the mechanism.

As shown in FIG. 20, the self-locking structure of this application may also be used for a wall bed structure 1011 to prevent spring back.
