Description

Rotary connecting structure of hidden retractable bed

Technical Field

The utility model belongs to the technical field of the technique of furniture and specifically relates to a hide rotation connection structure of shrink bed.

Background

For many people living in cities, the public hopes to have a larger room for living, but for economic reasons, the area of the room is always large, so that the use efficiency of the space in a limited space is required to be improved, and therefore, the bed is combined with an outer frame, so that the bed can be hidden in the outer frame when not in use and can be rotated out of the outer frame for use when in use, and the frame can be made into a bookshelf or a shelf for use, so that the bed does not occupy too much space when not in use, and the outer frame is not useless.

The bed of this kind of current includes outer frame and bedstead, the bedstead is in outer frame and the bedstead rotates with outer frame to be connected, the bedstead is close to the both ends of two risers of outer frame and is pegged graft respectively and has a connecting bolt, it supplies connecting bolt to pass to have seted up the through-hole on the bedstead, connecting bolt passes the riser of outer frame again after passing the bedstead, it is fixed with it to reuse the nut at last, it supplies connecting bolt to pass to have seted up the perforation on the riser of outer frame, diameter because of the perforation is greater than connecting bolt, make connecting bolt rotate in the perforation, and then make the bedstead just can follow outer frame and roll out, thereby realize bedstead and outer frame rotation connection's purpose.

The above prior art solutions have the following drawbacks: use connecting bolt and nut to reach the purpose that bedstead and outer frame are rotated and are connected, need frequent the rotation because of the bedstead, the bedstead is when rotating, and connecting bolt also follows the rotation easily, and when connecting bolt rotated, just takes place relative rotation with the nut easily for the nut is from connecting screw rod and is unscrewed, causes the condition that the bedstead breaks away from outer frame to appear, so remains to improve.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a hide rotation connection structure of shrink bed, it has the effect that makes more firm stable of bedstead and outer frame attach.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a hide rotation connection structure of shrink bed, includes bedstead and outer frame, the bedstead sets up in outer frame to the bedstead rotates with outer frame to be connected, still include the plug connector and cup joint the piece, the plug connector is pegged graft and is close to outer frame riser one end and with bedstead detachable connections at the bedstead, cup joint the piece and rotate to set up on the surface that is close to bedstead one side at outer frame riser lower extreme, cup joint the piece and be close to bedstead one side and be provided with the jack on the surface, the plug connector is close to outer frame riser one end and pegs graft in the jack, and the lateral surface of one end and the lateral wall butt of jack are in the plug connector.

By adopting the technical scheme, when the bedstead is placed in the outer frame, the plug connector is firstly inserted on the bedstead, meanwhile, one end of the plug connector, which is far away from the bed frame, is inserted into the jack, the plug connector is fixedly connected with the bed frame, because the side surface of one end of the plug connector, which is positioned in the jack, is abutted against the side wall of the jack, the cross section of the jack is polygonal, when the bedstead rotates, the plug connector rotates along with the bedstead, the socket joint piece also rotates along with the bedstead, and the bedstead is rotationally connected with the outer frame because the socket joint piece rotates and is arranged on the vertical plate of the outer frame, and as long as the bedstead is close to outer frame riser one end and the distance between the outer frame riser does not change, the jack just can not be pulled out to the plug connector, compares in the mode that couples together bedstead and outer frame through bolt and nut, and this kind of mode makes bedstead and outer frame attach more firmly stable, difficult not hard up.
