Description

Technical Field

[0001] The utility model relates to the technical field of household products, and particularly relates to a detachable connection structure of a bed frame and a bed frame. Background Art

[0002] In the related art, the bed frame includes longitudinals arranged oppositely, crossbars connected between the longitudinals, and support feet. Both ends of the oppositely arranged longitudinals are respectively connected to the headboard frame and the footboard frame. To save the packaging volume, the longitudinals are arranged in a segmented manner, generally in two segments, and the two segments of longitudinals are hinged. In the prior art, screws or bolt structures are usually used to connect the longitudinals, crossbars, and support feet to each other. For example, a high-stability bed frame connecting piece and an assembled bed frame disclosed in the authorized publication number CN212803878U use bolts to fix the longitudinals, crossbars, and support feet.

[0003] With the increasing requirements for packaging dimensions, each component of the bed frame adopts a segmented hinge design. At this time, the traditional screw / bolt connection method makes the installation more complex and cumbersome, and improper installation is likely to cause interference to the segmented hinge part. To solve the above problems, the prior art uses a combination of a pipe plug and a bolt or only a pipe plug connection between the segmented longitudinals. The pipe plug is connected to the crossbar. For example, a bed foot structure and a bed frame convenient for disassembly and assembly disclosed in the authorized publication number CN212912460U, but such a connection method makes the connection of the middle crossbar, which is an important load-bearing part, not firm enough and prone to shaking.

Guide grooves 2212 are also provided on both sides of the entrance of the inner plug-in 221 to facilitate the insertion of the elastic pin 41 at the end of the crossbar 3. Self-locking holes 42 are provided on both sides of the inner plug-in 221 and the outer plug-in 222 for the elastic pin 41 at the end of the crossbar 3 to be inserted for locking.

[0041] Specifically, the adjustment and positioning mechanism 5 includes a connecting member 51 and a positioning member 52. The connecting member 51 axially forms a first through hole 511 and a second through hole 512 for the first cross bar 31 and the second cross bar 32 to pass through, that is, the first through hole 511 is for the first cross bar 31 to pass through, and the second through hole 512 is for the second cross bar 32 to pass through. The connecting member 51 is provided with a first card slot 513 and a second card slot 514. The first card slot 513 communicates with the first through hole 511, and the second card slot 514 communicates with the second through hole 512. The positioning member 52 includes a first positioning member 521 and a second positioning member 522. The first positioning member 521 is received in the first card slot 513 to position the first cross bar 31 passing through the first through hole 511; the second positioning member 522 is received in the second card slot 514 to position the second cross bar 32 passing through the second through hole 512. Different grooves 33 are respectively provided on the first cross bar 31 and the second cross bar 32 along the length direction, and different groove 33 positions correspond to different width dimensions, that is, when the positioning member 52 is clamped into the grooves 33 at different positions of the first cross bar 31 and the second cross bar 32, a bed frame with different width dimensions is formed.

[0042] The positioning member 52 is an L-shaped member, including a fixing rod 523 and a mounting rod 524. The fixing rod 523 cooperates with the grooves 33 of the first cross bar 31 and the second cross bar 32 for fixation, and the mounting rod 524 is arranged on the connecting member 51. Specifically, the connecting member 51 is further provided with a mounting hole 515. The mounting rod 524 passes through the mounting hole 515 and extends out of the connecting member 51.

The elastic member 525 can be a compression spring. The limiting structure includes a threaded portion 526 provided on the mounting rod 524 and a nut 527 connected to the threaded portion 526. The elastic member 525 is provided between the nut 527 and the connecting member 51.

[0043] When adjusting the connection positions of the first cross bar 31 and the second cross bar 32 with the connecting member 51, the mounting rod 524 is moved to compress the elastic member 525, so that the fixing rod 523 disengages from the grooves 33 of the first cross bar 31 and the second cross bar 32. At this time, the first cross bar 31 and the second cross bar 32 can move relative to the connecting member 51. When moved to the target width position, the fixing rod 523 is re-clamped into the grooves 33 of the first cross bar 31 and the second cross bar 32 under the elastic reset action of the elastic member 525 for fixation. In addition, when the fixing rod 523 disengages from the grooves 33 of the first cross bar 31 and the second cross bar 32, the first cross bar 31 and the second cross bar 32 can completely disengage from the connecting member 51, so that during packaging, the first cross bar 31 and the second cross bar 32 can be freely placed, and the packaging size is smaller.

[0044] When the bed frame is packaged, the middle crossbar 3 and the plug-in part 2 can be easily separated through the self-locking mechanism 4. Subsequently, the first longitudinal rod 11 and the second longitudinal rod 12 are rotated and folded to be parallel to each other through the hinge piece 13; the crossbar 3 is retracted to the state with the minimum width, and the folding support feet are folded; then all the segmented parts are stacked and packaged, reducing the packaging volume, and the installation can be carried out without using any tools. Only need to unfold each segmented part and insert the crossbar 3 through the self-locking mechanism 4 to complete the assembly.

[0045] A bed frame according to an embodiment of the present invention. Since the ends of the first longitudinal rod 11 and the second longitudinal rod 12 are hinged, the plug-in part 2 is fixedly connected to the first longitudinal rod 11 or the second longitudinal rod 12. The end of the first crossbar 31 of the middle crossbar 3 is detachably inserted into the slot 21 of the plug-in part 2 connected to the first longitudinal rod 11 of one of the longitudinal rods 1. The end of the second crossbar 32 of the middle crossbar 3 is detachably inserted into the slot 21 of the plug-in part 2 connected to the second longitudinal rod 12 of the other longitudinal rod 1. A self-locking mechanism 4 is provided between the first crossbar 31 and the second crossbar 32 and the slot 21 of the plug-in part 2 respectively. The first crossbar 31 and the second crossbar 32 are connected through an adjustment and positioning mechanism 5. Thus, it is not necessary to use bolts or screws to connect the longitudinal rod 1 and the crossbar 3, and the connection between the longitudinal rod 1 and the crossbar 3 is stable, making the overall connection of the bed frame firm and the fit tight, and improving the problem that the longitudinal rod 1 is prone to shaking.

[0046] At the same time, the middle crossbar 3 is provided with support feet 6. The support feet 6 are hinged to the middle crossbar 3, and the hinged position is before the elastic pin 41. The support feet 6 can be freely folded and unfolded. When folded, they are parallel to the middle crossbar 3, and when unfolded, they are perpendicular to the middle crossbar 3, making the overall force of the bed frame more balanced. When the bed frame is adjusted to the maximum width, it can still ensure that each part of the bed frame has sufficient support strength.
