Description

Folding bed frame with hinge

Technical Field

The utility model relates to a folding bed field, in particular to folding bed frame with hinge.

Background

The folding bed is convenient and saves the volume and space, is folded and folded in various folding modes, has the advantages of light weight, large bearing capacity, convenient carrying, convenient installation and the like, and is widely used for accompanying and attending in hospitals, traveling outside, rescuing and the like. The folding bed body on the market adopts stainless steel construction more, have the but very weak of plastics, and the structure is complicated, the weight is heavy, it is very inconvenient to carry, and the bed frame on the folding bed includes the head of a bed, first middle part, the second middle part, four bibliographic categories such as tailstock, wherein for the stability of folding bed, first middle part, get up by hinge connection usually between the second middle part, in order to alleviate the weight of folding bed and improve the mechanical properties of bed frame, hollow structure is generally made to the bed frame, current mounting method passes through the screw snap-on at the surface of bed frame with the hinge, this kind of fixed approach is not only pleasing to the eye, it is also very troublesome on the bed frame to install the hinge, it is very unstable, and when folding the folding bed is packed up, because the hinge is fixed outside the bed frame, also make the folding bed can not pack up completely.

SUMMERY OF THE UTILITY MODEL

The utility model discloses mainly solve: the first middle part on the existing folding bed is inconvenient to pass through hinge connection with the second middle part, and the hinge directly passes through the fix with screw at the bed frame surface, and is not only unsightly, makes the folding bed can't pack up completely moreover, in order to solve above-mentioned problem, the utility model aims at providing a folding bed frame with hinge.

The purpose of the utility model is realized with the following mode: a folding bed frame with hinges comprises four sections of aluminum profiles, namely a bed head, a first middle part, a second middle part and a bed tail; the bed head is connected with the first middle part and the bed tail is connected with the second middle part through the connecting pieces respectively, the first middle part and the second middle part are connected through hinges, the first middle part and the second middle part respectively comprise two aluminum profile rods arranged in parallel, the aluminum profile rods are provided with cavities, each hinge comprises two blades, a first cylinder is fixed on the middle part of the side face of one blade, a second cylinder is fixed on each of the two ends of the side face of the other blade, the first cylinder and the second cylinder are hinged through primary and secondary rivets, a plug is fixed on each blade, and the plug is inserted into the cavities in the first middle part and the second middle part.

The plug is provided with a first through hole, and the part of the bed frame corresponding to the first through hole is provided with a second through hole.

The outer side surface of the blade is higher than the outer side surface of the plug.

The connecting piece is in an inverted U shape, and the end part of the bed head and one end of the first middle part are hinged with the connecting pieces respectively; one end of the second middle part and the end part of the bed tail are respectively hinged with the connecting piece.

Compared with the prior art, the utility model discloses can insert the cavity at first middle part and second middle part through the plug on the hinge in, make its interference fit for the hinge is not fixing outside the bed frame, has improved the installation effectiveness, is equipped with the through-hole on the plug moreover, can make the more stable fixing of hinge on the bed frame.

Detailed Description

As shown in fig. 1-7, a folding bed frame with hinges comprises four sections of aluminum profiles, namely a bed head 1, a first middle part 2, a second middle part 3 and a bed tail 4; the bed head 1 is hinged with the first middle part 2, the bed tail 4 is hinged with the second middle part 3 through connecting pieces, the first middle part 2 and the second middle part 3 both comprise two aluminum profile rods 5 which are arranged in parallel, the aluminum profile rods 5 are provided with cavities, the weight of the bed frame is reduced, and the mechanical property of the bed frame is improved, first middle part 2, second middle part 3 between link together through hinge 6, hinge 6 includes two blades, be fixed with a first drum 7 on the middle part of the side of a blade, the both ends of the side of another blade respectively are fixed with a second drum 8, first drum 7 articulates through primary and secondary rivet 9 with second drum 8, be fixed with a plug 10 on every blade, in the cavity of first middle part 2 and second middle part 3 was pegged graft to plug 10, plug 10 and bed frame interference fit to make the bed frame of folding bed articulated through hinge 6.

The plug 10 on be equipped with a first through-hole 11, seted up first through-hole 11 on the part of bed frame and first through-hole 11 correspondence, fixed with the second through-hole through first through-hole 11 with the bolt to make hinge 6 more stable fix on the bed frame.

The outer side surface of the blade is higher than the outer side surface of the plug 10, so that the hinge 6 is more smoothly fixed on the bed frame.

The connecting piece is in an inverted U shape, and the end part of the bed head 1 and one end of the first middle part 2 are respectively hinged with the connecting piece; one end of the second middle part 3 and the end part of the bed tail 4 are respectively hinged with a connecting piece.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
