The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Example 1

Referring to fig. 1-2, the embodiment of the present utility model provides a support frame, which includes a frame body including a cross bar 1, and a front cross bar 2 and a rear cross bar 3 formed at front and rear ends of the cross bar, respectively, wherein the front cross bar 2 and the rear cross bar 3 each include a

left fork portion

21,31 and a

right fork portion

22,32, and the

left fork portion

21,31 and the

right fork portion

22,32 are connected with an upper support bar 100,101,102,103 and a lower support bar 200,201,202,203 in a detachable or foldable manner; referring to fig. 3 and 4, four lower support poles 200,201,202,203 form a support foot rest adapted to be supported on the ground, and four upper support poles 100,101,102,103 form a support head rest adapted to support household items including, but not limited to, a table top 300 or a support chair 400.

Specifically, referring to fig. 3, when the stand is used as a support frame for a table, four lower support bars form a support stand, four upper support bars form a support top frame, and the four upper support bars are positioned horizontally after being positioned on the support top frame with the heights of the four upper support bars being level with 100,101,102, 103.

Referring to fig. 4, when the bracket is used as a support frame of a chair, the upper support rods 101,102 connected by the rear cross-connect are higher than the upper support rods 100,103 connected by the front cross-connect, and the difference in height between the rear cross-connect and the front cross-connect is suitable for providing a sitting and lying space when the soft-sided support of the chair is mounted on the support roof.

Compared with the supporting frame provided by the prior art, the front cross connecting piece 2 and the rear cross connecting piece 3 are formed in front of and behind the cross rod to form the double Y-shaped frame body, so that the supporting span of the lower supporting rod is obviously increased, and the stability of the supporting frame is obviously improved.

Since the front cross-connect 2 and the rear cross-connect 3 are identical in structure, the left fork 21 and the right fork 22 of the front cross-connect 2 are also substantially identical in structure, and the following reference numerals are given only to the left fork. The left fork part 21 and the right fork part 22 are respectively provided with an upper jack 23 and a lower jack 24 which are suitable for the insertion of the upper support rod 100 and the lower support rod 200; in this way, the upper support bar 100 and the lower support bar 200 can be directly inserted into the left fork portion 21 and the right fork portion 22, so as to facilitate the storage of the support frame.

In some embodiments, in order to avoid the upper support rod 100 and the lower support rod 200 from being lost, the upper jack is connected with the upper support rod through an elastic rope 25, and the lower jack is connected with the lower support rod through an elastic rope 26, so that even if the upper support rod 100 and the lower support rod 200 are detached from the Y-shaped frame body through traction of the elastic rope, the upper support rod 100 and the lower support rod 200 are still connected with the cross rod through the elastic rope, and are not easy to be lost.

In this embodiment, as shown in fig. 5, the left fork portion 21 and the right fork portion 22 are directly and fixedly connected to the cross bar. Specifically, the left and right fork portions each have a fork bar 210 and a connector 211 formed at an end of the fork bar 210, and the connectors form an upper insertion hole 23 extending obliquely upward and a lower insertion hole 24 extending obliquely downward, so that when the support frame is required to be used, the upper support bars 100,101,102,103 and the lower support bars 200,201,202,203 are inserted into the Y-shaped frame body through the upper insertion holes and the lower insertion holes, respectively, and when the support frame is not required, the upper support bars 100,101,102,103 and the lower support bars 200,201,202,203 are pulled out from the upper insertion holes and the lower insertion holes of the Y-shaped frame body.

In addition, the height of the length of the two upper support bars connected by the rear cross-connection member may be extended, so that the support frame can be switched between the chair frame and the table frame by adjusting the heights of the four upper support bars 100,101,102, 103.

Illustratively, the two upper support rods are telescoping rods that can be lengthened or shortened in height.

Example 2

The embodiment is basically the same as embodiment 1, and the only difference is that the left fork portion and the right fork portion provided in the embodiment are detachably connected to the cross bar, as shown in fig. 6, the left fork portion and the right fork portion each have a fork rod and a connector formed at an end of the fork rod, two ends of the cross bar 1 respectively form Y-

type adapters

11, 12, the Y-type adapters 11 form a left jack 110 and a right jack 111, and the fork rods 210 of the left fork portion and the right fork portion are respectively inserted into the left jack 110 and the right jack 111, so that the Y-type frame body can be folded to be in a bundle structure, and the storage volume is remarkably reduced.

Specifically, in order to prevent the left and right fork portions from being lost, an elastic rope 112 is connected between the left and right fork portions and the cross bar;

example 3

As shown in fig. 7, this embodiment is substantially the same as embodiment 1, and the only difference is that the left fork portion and the right fork portion provided in this embodiment are hinged on the cross bar, so that the front cross connecting member and the rear cross connecting member can be switched between a folded position and an unfolded position, when the front cross connecting member and the rear cross connecting member are in the unfolded position, compared with the cross bar, the front cross connecting member and the rear cross connecting member are in the folded position, and when they are in the folded position, they are folded together with the cross bar, so that the Y-shaped frame body is stored in a bundle structure by means of hinged connection, and the storage volume is significantly reduced.

Illustratively, two ends of the cross bar 1 are respectively provided with a Y-

shaped adapter

11 and 12, and the fork bars of the left fork part and the right fork part are hinged and connected with the left fork part and the right fork part of the Y-shaped adapter.

In the description herein, reference to the term "embodiment," "example," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples.
