Abstract

The utility model discloses a folding supporting frame pin-jointed which is formed by a plurality of groups of crossing holding poles through pivoting. Top and bottom parts of the holding poles of consecutive two groups are pivoted to form upper and inferior supporting points. The homolateral consecutive two groups of crossing poles are added with a group of crossing poles, wherein the inferior extremity provides with two poles forming inferior holding points and the middle part pivots with two poles forming inferior holding points, the supper extremity is parallel to upper holding points, which forms supporting reinforced points. The utility model increases several supporting reinforced points than present supporting frame to make the support more solid.

Description

A kind of folding support frame

Technical field

The utility model relates to a kind of folding support frame.

Background technology

Usually, the folding support frame structure of travelling bed and elongated Travelling desk etc. as shown in Figure 1, 2, form by the 1 ' pivot joint of many groups crossing branching rod, the top of the crossing branching rod 1 ' of two adjacent groups or bottom are articulated and form some strong points 2 ' and 3 ', wherein upper support point 2 ' is used to support bed surface or desktop 4 ', lower support point 3 ' then supports on the ground, and whole travelling bed and Travelling desk are propped.

The folding support frame of this structure, bed surface or desktop 4 ' support the location by several upper support points 2 ' fully, and the strong point is few, support force is concentrated and is acted on several points, when lying people or when putting article on bed surface or the desktop 4 ', gravitate very easily causes bed surface or desktop 4 ' to stay even damaged.Therefore, existing folding support frame is improved, promoted the fastness that supports, be necessary in fact.

The utility model content

The folding support frame that provides a kind of support more firm is provided the purpose of this utility model.

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

A kind of folding support frame, form by some groups of crossing branching rods pivot joints, the top of the crossing branching rod of two adjacent groups and bottom are articulated and form the upper and lower strong point respectively, on two groups of adjacent crossing branching rods of homonymy, increase by one group of crossbar, the lower ending pivot of this crossbar is connected on two poles that form lower support point, the centre of this crossbar is articulated in two poles that form upper support point, and the upper end of this crossbar is concordant with upper support point, constitutes the bracing reinforcement point.

After adopting said structure, the utility model has obviously increased several bracing reinforcement points than existing bracing frame, the support force peptizaiton is on each aspect, be subjected to the together support of upper support point and bracing reinforcement point, can support bed surface or desktop more firmly and go up article, when putting article on lie on the bed surface people or the desktop, gravity acts on upper support point and bracing reinforcement point, avoids causing bed surface or desktop to stay and breakage.

Fig. 2 is a schematic perspective view of commonly using product;

Fig. 3 is a side view of the present utility model;

Fig. 4 is a schematic perspective view of the present utility model.

The specific embodiment

See also shown in Fig. 3,4, the utility model has disclosed a kind of folding support frame, is articulated by some groups of crossing branching rods 1 to form, and the top of the crossing branching rod 1 of two adjacent groups and bottom are articulated and form the upper and lower strong point 2 and 3 respectively.

The improvement of this case is to increase by one group of crossbar 5 on two groups of adjacent crossing branching rods 1 of homonymy, the lower ending pivot of this crossbar 5 is connected on two poles 1 that form lower support point 3, the centre of this crossbar 5 is articulated in two poles 1 that form upper support point 2, it is 2 concordant that the upper end of this crossbar 5 and upper support are put, and constitutes bracing reinforcement point 6.

The utility model is compared with existing bracing frame, several bracing reinforcement points 6 have obviously been increased, the support force peptizaiton is on each aspect, be subjected to the together support of upper support point 2 and bracing reinforcement point 6, can support bed surface 4 or desktop more firmly and go up article, when putting article on lie on the bed surface people or the desktop, gravity acts on upper support point 2 and bracing reinforcement point 6, avoids causing bed surface 4 or desktop to stay and breakage.

Claims (1)

1, a kind of folding support frame, form by some groups of crossing branching rods pivot joints, the top of the crossing branching rod of two adjacent groups and bottom are articulated and form the upper and lower strong point respectively, it is characterized in that: on two groups of adjacent crossing branching rods of homonymy, increase by one group of crossbar, the lower ending pivot of this crossbar is connected on two poles that form lower support point, the centre of this crossbar is articulated in two poles that form upper support point, and the upper end of this crossbar is concordant with upper support point, constitutes the bracing reinforcement point.
