Description

Technical Field

[0001] The utility model relates to the field of cross plates of the bed frame of a soft-pack bed, in particular to a quick-release connection structure for the cross plates of the bed frame. Background Art

[0002] A soft-pack bed is a kind of bed integrating comfort and decoration. Its main feature is that the surface of the bed body is wrapped with a layer of soft padding material, usually mainly made of leather, fabric or synthetic materials. The design of the soft-pack bed not only improves the comfort of the bed, but also increases its aesthetic degree, making it an important part of modern home design. The designs of soft-pack beds are diverse, covering from simple modern to luxurious classical. The soft-pack part is usually composed of high-density foam, cotton filling or other elastic materials, which can provide good support and comfort. The outer covering material can be natural leather, imitation leather, suede cloth or other decorative fabrics, which not only improve the visual effect of the bed, but also increase the comfort of the touch. Compared with traditional beds, the soft-pack bed adds a soft wrapping layer at the edge and head of the bed body, which can effectively avoid the injury caused by collision at the edge or head of the bed, and is especially suitable for families with children.

[0003] The existing bed frames of soft-pack beds are all integrated. If any cross plate is broken and cannot be used anymore, it will be very troublesome.

An adjustment gear 9 is fixedly connected to the middle end of the outer wall of the rotating rod 7. A plurality of return springs 11 are arranged inside the adjustment groove. One end of the return spring 11 is fixedly connected to the top side of the inner wall of the adjustment groove, and the other end of the return spring 11 is fixedly connected to the top end of the control rack 10. The front and rear sides of the control rack 10 are meshed with the adjacent sides of the outer walls of the two adjustment gears 9 to control the rotation of the two rotating rods 7. A limiting block 8 is fixedly connected to the outer wall of the rotating rod 7. Limiting grooves are provided on both the front and rear sides of the metal support block 4. The top side of the inner wall of the limiting groove abuts against the top side of the limiting block 8. When one of the transverse support frames 3 is broken or damaged, grasp the fixing block 6 and pull it. The fixing block 6 drives the control rack 10 to slide upward. The control rack 10 and the return spring 11 are compressed. The two sides of the control rack 10 are meshed with the adjustment gears 9 to drive the rotating rods 7 to rotate. The rotation of the rotating rods 7 drives the limiting blocks 8 to rotate downward, so that the limiting blocks 8 are disengaged from the limiting grooves, and the restraint of the metal support block 4 on the transverse support frame 3 is released. Replace the transverse support frame 3. After the replacement is completed, place the transverse support frame 3 back into the inner wall of the metal support block 4 and release the fixing block 6. The return spring 11 rebounds to drive the limiting block 8 to reset and fix the metal support block 4 and the transverse support frame;

Under the action of the torsion spring, the sheet clamping block 5 resets to clamp the sheet; if the size of the mattress changes, unscrew the limiting screw 14, slide the limiting screw 14 and then tighten the limiting screw 14 to change the length of the extension slider 12 extending out of the transverse support frame 3.

[0026] Working principle: When a horizontal support frame 3 is broken or damaged, grasp the fixing block 6 and pull it. The fixing block 6 drives the adjusting rack 10 to slide upward. The adjusting rack 10 compresses the return spring 11. The two sides of the adjusting rack 10 mesh with the adjusting gear 9 to drive the rotating rod 7 to rotate. The rotation of the rotating rod 7 drives the limiting block 8 to rotate downward, so that the limiting block 8 disengages from the limiting groove, and the restraint of the metal support block 4 on the horizontal support frame 3 is released. Replace the horizontal support frame 3. After the replacement is completed, place the horizontal support frame 3 back into the inner wall of the metal support block 4 and release the fixing block 6. The return spring 11 rebounds to drive the limiting block 8 to reset and fix the metal support block 4 and the horizontal support frame 3. If it is necessary to fix the sheets on both the left and right sides, rotate the sheet clamping block 5, place the sheet at the gap between the sheet clamping block 5 and the mattress, and release the sheet clamping block 5. Under the action of the torsion spring, the sheet clamping block 5 resets to clamp the sheet; if the size of the mattress changes, unscrew the limit screw 14, slide the limit screw 14 and then tighten the limit screw 14, and change the length of the extension slider 12 extending out of the horizontal support frame 3.
