The present invention relates to the technical field of beds, and in particular to a headboard structure of a bed.
An existing conventional iron frame bed includes a headboard, a footboard, and a bed surface frame arranged between the headboard and the footboard; the headboard and the footboard are extended to also serve as bed supporting legs of the iron frame bed. Generally, an existing headboard has an integrated structure and includes a left supporting rod, a right supporting rod, an upper connecting rod, a lower connecting rod, and a plurality of longitudinal supporting rods arranged between the supporting rods and the connecting rods. At present, the headboard is often made to have a certain height to provide back resting function for users, causing a larger size of the headboard which is not inconvenient to package and transport, and in case of transport, the transportation cost is high.
It is an object of the present invention to provide a headboard structure, which has the advantages of having telescopic components to aid in size reduction of the headboard structure and thus reducing the transportation cost.
To achieve the above object, the present invention adopts the following solutions:
A headboard structure, comprising an upper connecting rod, a lower connecting rod, two supporting rods, and a plurality of longitudinal telescopic rods;
Further, at least two longitudinal telescopic rods are each provided with the positioning structure.
Further, a lower end of each sleeve pipe is fixed to the lower connecting rod; and a sliding cavity is formed inside each sleeve pipe, and the sliding cavity is in communication with an upper end of the sleeve pipe; an upper end of each sub-rod is fixed to the upper connecting rod; and a lower end of each sub-rod is movably inserted in a corresponding sliding cavity.
Further, a length of each sub-rod is not greater than a depth of the corresponding sliding cavity.
Further, each of the longitudinal telescopic rods further comprises a hollow plug, the hollow plug is provided with a plug body which has a hole penetrating through an upper end and a lower end of the hollow plug; a periphery of the upper end of the plug body is provided with a flange extending radially from the plug body; and the plug body sleeves the sub-rod and is inserted into the sliding cavity of the sleeve pipe; the flange is limited and abutted against an upper end surface of the sleeve pipe.
Further, at least one sub-rod is provided with a cavity inside, a sidewall of the lower portion of said at least one sub-rod has an opening in communication with the cavity; the spring loaded buckle comprises a V-shaped spring sheet and the buckle pin; the V-shaped spring sheet of the spring loaded buckle is located in the cavity, and the buckle pin of the spring loaded buckle extends out of the opening from the cavity; a sliding cavity is formed inside each sleeve pipe; the lower portion of said at least one sub-rod is inserted downwardly to the sliding cavity of a corresponding sleeve pipe and is slidable therein; and a corresponding positioning hole is in communication with the sliding cavity.
Further, the upper portion of the sleeve pipe of each of the longitudinal telescopic rods is further sleeved by a protective sleeve; the protective sleeve is internally provided with a through hole penetrating through an upper end and a lower end of the protective sleeve, and the through hole allows the sleeve pipe to pass through.
Further, each of a left end and a right end of the upper connecting rod is bent downwards to form a lower connecting portion; two lower connecting portions at said left end and said right end of the upper connecting rod respectively sleeve and connect to upper connecting portions provided at upper portions of the two supporting rods; and two ends of the lower connecting rod are respectively detachably locked at middle portions of the two supporting rods.
Further, an outer diameter of each of the upper connecting portions is smaller than an inner diameter of a corresponding lower connecting portion; side walls of each of the upper connecting portions and side walls of the corresponding lower connecting portion are provided with aligned penetrating holes; a fixing bolt is provided to penetrate the penetrating holes and lock the upper connecting portion and the corresponding lower connecting portion in cooperation with a nut.
According to the above structures, because the longitudinal telescopic rods have the sub-rods and the sleeve pipes telescopically disposed in relation to each other, after the lower connecting rod is disengaged from the two supporting rods, positioning function of each positioning structure can be released by pressing a respective buckle pin, so that a distance between the upper connecting rod and the lower connecting rod can be adjusted whereby the sub-rods are telescopically retracted into the sleeve pipes respectively, thereby greatly reducing the height of the headboard, reducing the size of the headboard and facilitating packaging and transportation. Also, by means of the positioning structure, at least one sub-rod and a corresponding sleeve pipe can be fixed against each other at an extended state. Specifically, during assembly, the upper connecting rod and the lower connecting rod are pulled apart from each other, thus driving the sub-rods to be telescopically withdrawn from the corresponding sleeve pipes until the buckle pin is inserted into the positioning hole in each positioning structure to achieve a fixed extended state of a respective pair of sub-rod and sleeve pipe. Accordingly, the headboard is also in a fixed extended state, and then the two supporting rods are sequentially installed to complete assembly. Further, the positioning structure also serves the function to avoid the problem that many sub-rods and sleeve pipes are difficult to match and assemble in case the sub-rods and the sleeve pipes are separated from each other completely, therefore, quick assembly can be achieved, and the installation efficiency is improved.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and thoroughly described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. The components of embodiments of the present application generally described and illustrated in the figures herein may be adaptable to various designs and configurations.
As shown in
The spring loaded buckle 51 is a conventional component and comprises said buckle pin 511 and a V-shaped spring sheet 512.
With reference to
In the present embodiment, at least two longitudinal telescopic rods 4 are each provided with the positioning structure 5, so that the positioning effect is enhanced. In the present embodiment, a total of seven longitudinal telescopic rods 4 are provided, and two longitudinal telescopic rods 4 at left and right sides of the middle longitudinal telescopic rod 4 respectively are each provided with said positioning structure 5.
Specifically, referring to
It is also possible to configure a length of each sub-rod 41 to be not greater than a depth of the corresponding sliding cavity 421, so that the sub-rod 41 can be completely accommodated inside the corresponding sleeve pipe 42 to minimize the packaging size of the headboard.
As shown in
As shown in
Each of the longitudinal telescopic rods 4 further comprises a hollow plug 43, the hollow plug 43 is provided with a plug body 431 which has a hole penetrating through an upper end and a lower end of the hollow plug; a periphery of the upper end of the plug body 431 is provided with a flange 432 extending radially from the plug body; and the plug body 431 sleeves the sub-rod 41 and is inserted into the sliding cavity 421 of the sleeve pipe 42, and the flange 432 is limited and abutted against an upper end surface 422 of the sleeve pipe 42.
The hollow plug 43 is configured to protect the upper end face 422 of the sliding cavity 421 of the sleeve pipe 42; impurities and the like are prevented from entering the sliding cavity 421 which may otherwise affect the sliding of the sub-rod 41 in the sliding cavity 421. Also, a gap between the sub-rod 41 and the sliding cavity 421 of the sleeve pipe 42 is shielded, so as to achieve safety protection.
In the present embodiment, each of a left end and a right end of the upper connecting rod 1 is bent downwards to form a lower connecting portion 11; two lower connecting portions 11 respectively sleeve and connect to upper connecting portions 31 provided at upper portions of the two supporting rods 3; and two ends of the lower connecting rod 2 are respectively detachably locked at middle portions of the two supporting rods 3.
