Description

A kind of bedstead link

Technical field

The utility model relates to bedstead, relates in particular a kind of bedstead link.

Background technique

In the bedstead commonly used, especially foldable bedstead, link spare generally need to be arranged as support in bedstead, a kind of folding bedstead as shown in Figure 1, unit bedstead group 1 ' comprises respectively upper frame group 11 ' and underframe group 12 ', upper frame group 11 ' includes two and is articulated in the cross bar 111 ' of connecting base 2 ' and two vertical poles 112 ' between two cross bars 111 ', also be provided with between two cross bars 111 ' and be provided with some crossbeam bars 114 ' between two longeron bars, 113 ', two vertical poles 112 ' to strengthen the upper frame group 11 ' holding strength to top mattress or bed board.Two cross bars 121 ' of underframe group 12 ' also are articulated on the connecting base 2 ' respectively.In the same unit bedstead group 1 ', be articulated with a connection piece 13 ' between the cross bar 111 ' of frame set and the cross bar 121 ' up and down, in order to supporting upper frame group 12 ', link 13 ' can be located at the middle part of two cross bars or with respect to the tail position of connecting base, also many links 13 ' can be set.

For such connecting-piece structure, between two cross bars of frame set, form supported rod erecting about it just is articulated in, and can when the bedstead folding, receive by realizing the folding of bedstead.But, in link, the upper and lower end place of link must be provided with respectively two pivot holes and be used for being articulated in bedstead, so in the pivot-connecting position, because bearing the load-bearing pressure from the bedstead top, so occur easily loosening in the pivot-connecting position, and support plate also must have larger thickness, and for such link because being a connecting piece body structure, support firm not, and against locating, also smooth and easy not in its turnover.

The model utility content

The purpose of this utility model is to provide a kind of bedstead link, and it has firm supporting, the smoothly advantage of transferring.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of bedstead link is connected between the upper lower cross bar of folding bedstead, and this bedstead link is for being the sheet body structure of " L " type, and it is provided with the pivot hole in the upper end portion of vertically holding, and a corner edges is then extended in the lower end, and corner edges is provided with the pivot hole; Link vertically holds the middle part of inner side surface to extend to form up or down a lug, and the length of this lug equates with distance between the upper lower cross bar.

The width of described corner edges is identical with the width of cross bar.

At least articulate two groups of links between the described upper lower cross bar.

After adopting said structure, bedstead is in deployed condition, and this bedstead link is when connecting support to two cross bars, and lug is just between two cross bars, thereby can play certain support to the compression weight of bedstead top, make the support of bedstead more firm; And bedstead is when carrying out folding, link by articulating between two cross bars, one end of link is provided with corner edges, this corner edges is connected on the side of cross bar just, can be so that more smooth and easy when the receipts of transferring are leaned between the cross bar, and it is more concentrated to distribute between each rod member after the closing after the folding, and folding is more convenient.

Embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

In conjunction with Fig. 2, shown in Figure 3, each unit bedstead group 1, two unit bedstead group 1 was articulated in respectively the connecting base 2 at middle part about folding bedstead comprised.

Wherein, unit bedstead group 1 comprises respectively upper frame group 11 and underframe group 12, upper frame group 11 includes two and is articulated in the cross bar 111 of connecting base 2 and two vertical poles 112 between two cross bars 111, also be provided with two longeron bars 113 between two cross bars 111, be provided with some crossbeam bars 114 between two vertical poles 112 to strengthen the holding strength of upper frame group 11 pairs of tops mattress or bed board, in underframe group 12, also be provided with longeron bar 123.Two cross bars 121 of underframe group 12 also are articulated in respectively on the connecting base 2, so connecting base 2 is provided with 4 pivot holes to connect cross bar 111 and cross bar 121.

In the same unit bedstead group 1, be articulated with at least one group of link 3 as supported rod erecting between the cross bar 111 of frame set and the cross bar 121 up and down, in order to supporting upper frame group 12, in the present embodiment, be articulated with two groups of links 3 between the upper frame group in unit bedstead group and the underframe group.Wherein, the up and down two ends of link 3 are articulated in respectively on cross bar 111 and the cross bar 121, link 3 of the present utility model, as shown in Figure 3, link 3 is one " L " matrix body structure, it is provided with pivot hole 31 in the upper end portion of vertically holding, can make on its wherein cross bar that is articulated in bedstead, and a corner edges 32 is extended in the lower end of link 3, the width of this corner edges 32 roughly width with cross bar is identical, be provided with a pivot hole 321 in corner edges 32, thereby the lower end that can make link 3 is articulated on the cross bar 112, and the middle part of vertically holding inner side surface at link 3, extend to form up or down a lug 33, the length of this lug 33 and cross bar 111 equate with distance between the cross bar 121, so bedstead is when deployed condition, the pivot hole 31 at the up and down two ends of link 3,321 when being connected on the cross bar, the two ends of lug 33 are resisted against on two cross bars, so the protrusion direction of lug 33 can be decided according to concrete connecting direction, lug 33 can be hooked the cross bar of bedstead, especially for the cross bar 111 in the upper frame group, has certain supporting effect.

Bedstead is when deployed condition, be articulated with link 3 between cross bar 111 and the cross bar 121, link 3 is as supporting rod, be provided with lug 33 in the link 3 of the present utility model, so link 3 is when connecting support to two cross bars, lug 33 is just between two cross bars, thereby can play certain support to the compression weight of bedstead top, link more than 3 obtains a stressed strong point, make the support of bedstead more firm, indirectly also can reduce the thickness of link 3, save certain cost of material.

Extremely shown in Figure 6 in conjunction with Fig. 4, when bedstead carries out folding, two unit bedstead groups 1 realize receiving by the connecting base 2 that is articulated in the middle part, in the folding process, upper frame group 11 in each unit bedstead group and underframe group 12 also cooperate simultaneously carries out folding, in upper frame group 11 and the underframe group 12, link 3 by articulating between cross bar 111 and the cross bar 121, link 3 an end be provided with corner edges 32, this corner edges 32 is connected on the side of cross bar 121 just, can so that between the cross bar transfer receive by the time more smooth and easy, and it is more concentrated to distribute between each rod member after the folding closing, folding is more convenient.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
