Abstract

The utility model discloses a connection structure of a folding bed rack, comprising two unit racks, two foot-rests and a middle support foot, wherein the foot-rests are pivoted on the outer part of the two unit racks and the middle support foot is arranged between the two unit racks. Each unit rack comprises two vertical rods and at least two transversal rods and the two ends of the two transversal rods are welded on the inner sides of the two vertical rods. Because the transversal rods of the two unit racks in the folding bed rack are welded on the vertical rods, thus the bed rack does not deform thus the support for the bed surface is staler and the stability of the folding bed rack is good.

Description

The syndeton of folding bedstead

Technical field

The utility model is about a kind of metal bed frame, is meant a kind of syndeton of folding bedstead especially.

Background technology

Traditional folding bedstead, mostly be to support a framework by folding foot rest to constitute, mostly framework is to be surrounded by two vertical poles and at least two cross bars, foot frame rod is to be fixed on the cross bar that is positioned at two ends, and cross bar and vertical pole are to adopt the relation that articulates, to make foot frame rod when folding, foot frame rod drives cross bar and can rotate relative to vertical pole, to fold together with framework.

But the pivot joint of above-mentioned cross bar and vertical pole relation makes the location between cross bar and the vertical pole uncertain, and the framework that makes cross bar and vertical pole constitute deforms easily, and the bed body that folding rack and bed surface are formed is easy to generate and rocks, and produces and supports unsteady phenomenon.

The utility model content

The purpose of this utility model provides a kind of syndeton that supports the good folding bedstead of steadiness.

For achieving the above object, solution of the present utility model is:

A kind of syndeton of folding bedstead comprises two unit support bodys, two foot-supporting frames and a middle part feet, and two foot-supporting frames are the outsides that are articulated in two unit support bodys, and the middle part feet is provided in a side of between the two unit support bodys; Each unit support body comprises two vertical poles and at least two cross bars, and the two ends of two cross bars are to be welded in two vertical pole inboards.

The inner pivot ear with pivoted hole that forms of two vertical poles of described two unit support bodys, two ends that articulate mast are to pass two unit support bodys to connect in the pivoted hole of pivot ear of closing so that two unit support bodys are joined together to form support.

Described each foot-supporting frame comprises main foot rest and auxilliary foot lever, and main foot rest comprises two montants and a cross bar, and the nearly middle part of two montants is connected by a cross bar; One end of auxilliary foot lever is articulated in the outside of montant, and the other end is articulated in the outside of two vertical poles, and two articulated sections are communicated with by a groove.

The upper end of two montants of described two foot-supporting frames is unidirectional lower end or unidirectional belows that are articulated in the nearly outer end of two vertical poles that are articulated in cross bar.

Described middle part feet comprises two perpendicular foot lever, a horizontal foot lever and two groups of side poles, the two ends of horizontal foot lever are fixed on the nearly middle part of two perpendicular foot levers, the top of each perpendicular foot lever articulates an end of both sides pole, the other end of both sides pole is articulated in the outside or the inboard of adjacent two vertical poles respectively, and the top of each perpendicular foot lever is a free end.

Form the inner concave arc surface of spacing pivot joint mast on the top end face of described each perpendicular foot lever.

Because the cross bar of two unit support bodys is to be welded on the vertical pole in the syndeton of the folding bedstead of the utility model, so frame-saw deformation can not take place in the bedstead that constitutes, and makes that its support to bed surface is more steady, and the steadiness that supports of the folding bed bedstead that constitutes is good thus.

The specific embodiment

As shown in Figure 1 to Figure 3, folding bedstead of the present utility model is to comprise that two unit support bodys 1, two foot-supporting frames 2 and a middle part feet 3 constitute.

Each unit support body 1 comprises that the inner of two vertical poles 11 and two cross bars, 12, two vertical poles 11 is extended with pivot ear 111, and each pivot ear 111 is provided with pivoted hole 112; Key of the present utility model is: wherein the two ends of a cross bar 12 be solid welding on the opposing end surface of the nearly outer end of two vertical poles 11, the upper end of two montants 211 of two foot-supporting frames 2 is unidirectional lower end or unidirectional belows that are articulated in two vertical poles, 11 nearly outer ends that are articulated in this cross bar 12; The two ends of another cross bar 12 are also to be that solid welding fixes on the opposing end surface at two vertical poles, 11 nearly middle parts.

Two vertical poles 11 of two unit support bodys 1 place that connects, by two pivot ears, 111 folded being close together in opposite directions, two ends that articulate mast 4 are passed two groups mutually behind the pivoted hole 112 of the folded pivot ear 111 that leans on, and are about to two unit support bodys 1 and link together.

Each foot-supporting frame 2 comprises main foot rest 21 and auxilliary foot lever 22, and main foot rest 21 comprises that the nearly middle part of two montants 211 and a cross bar 212, two montants 211 is connected 211 one spacing supporting roles of two montants by a cross bar 212; One end of auxilliary foot lever 22 is articulated in the outside of montant 211, the other end is articulated in the outside of two vertical poles 11, and two articulated sections are communicated with by a groove 221, so make articulated part slide in this groove 221, so that foot-supporting frame 2 can fold closing below unit support body 1.The setting of auxilliary foot lever 22 is the support strengths that further improve 2 pairs of bed surfaces 5 of foot-supporting frame herein.

Middle part feet 3 comprises two perpendicular foot lever 31, one horizontal foot lever 32 and two groups of side poles 33, the two ends of horizontal foot lever 32 are fixed on the nearly middle part of two perpendicular foot levers 31, to erect the one spacing supporting roles of foot lever 31 tools to two, the top of each perpendicular foot lever 31 articulates an end of both sides pole 33, the other end of both sides pole 33 is articulated in the outside or the inboard of adjacent two vertical poles 11 respectively, the top of each perpendicular foot lever 3 is a free end in addition, and on this end face, form inner concave arc surface 311, cooperate support and position-limiting action above-mentioned pivot joint mast 4 is had one.

Cooperate shown in Figure 2, bedstead of the present utility model upon deployment, each foot-supporting frame 2 is to be in deployed condition, and middle part feet 3 also is in deployed condition, the two ends that meanwhile articulate mast 4 are to ride against in the cancave cambered surface 311 on two perpendicular foot lever 31 tops.This shows that one articulates the effect that mast 4 has replaced two cross bars in each unit support body 1 in the existing bracing frame herein, one articulates the effect that 4 pairs of two unit support bodys 1 of mast have support simultaneously.

As shown in Figure 3, when bracing frame of the present utility model when folding, two unit support bodys 1 fold for axial bed surface 5 belows with the pivot joint mast 4 at middle part, two foot-supporting frame 2 closings on the bottom surface of each unit support body 1 simultaneously can be finished folding of whole bracing frame.

By said structure, the unit support body 1 that constitutes of cross bar 12 and vertical pole 11 solid weldings as can be known, its frame-saw is firm, can not produce deformation, and is therefore more steady to the support meeting of bed surface 5, and it is good to form the steadiness that the folding bed bedstead supports.
