Embodiment 1

[0026] This example is composed of two unit support frames I and II. Each unit support frame is provided with an upper umbrella frame A and a lower umbrella frame B. The upper umbrella frame is hinged on the hinge head 6 of the upper umbrella frame by the lower ends of four support rods 1. Four vertical vertical walls at 90 degrees to each other on the upper side (see Figure 12 ), the lower umbrella frame is composed of four support rods 2 hinged on the lower side of the lower umbrella frame hinge head 14 in the same form, the upper and lower umbrella frames cross each other, and the corresponding support rods of the two umbrella frames are respectively two by two Cross hinge connection.

[0027] This example is positioned at the lower umbrella frame support rod lower end of longitudinal integral support frame end and is covered with anchor 5, and the lower end of reinforcement rod 3 is hingedly connected with sliding sleeve 4 that is enclosed within the lower umbrella frame ...

Embodiment 2

[0034] See Figure 6 In this example, the lower end of the reinforcement bar 3 located at the end of the longitudinal support frame is hingedly connected with the sliding sleeve 4 that slides and fits on the lower umbrella support bar 2, and the upper end is connected with the upper hinge of the upper umbrella support bar 1, and the desktop fixed block 16 is fixed on the upper end of the upper umbrella stand support rod 1 that stretches out obliquely.

[0035] See Figure 6 , 7 In this example, the desktop fixing block 12 at the junction of the two unit support frames is fixed on the upper hinge head 11, and the ends of the horizontal rods 15 and 13 respectively located in the two unit support frames and the step surface of the desktop fixing block 12 pass through elastic plugs. and the socket make the two horizontal bars and the desktop fixing block 12 flush and elastically buckled and connected.

[0036] In this example, the upper end of the upper vertical support rod 10 ...

Embodiment 3

[0039] See Figure 10 , this example is provided with a vertical reinforcing rod 17 in the middle part of each unit support frame, and the vertical reinforcing rod slides and fits through the upper umbrella frame hinge head 6 and the lower umbrella frame hinge head 14. The desktop fixing block 18 is movably connected with vertical horizontal reinforcing rods, so that when the desktop is lapped on the horizontal rods on both sides, the horizontal reinforcing rods in the middle can support the desktop from the center, while the vertical reinforcing rods can also be aligned on the upper side. , The lower umbrella frame plays a reinforcing role.

[0040] In this example, one end of the horizontal reinforcing rod 19 movably connected on the reinforcing desktop fixing block 18 is hingedly connected with the desktop fixing block, the lower end of the oblique support rod 20 is hingedly connected with the upper umbrella stand hinge head 6 below, and the oblique upper end is connected w...

Abstract

A supporting frame of foldable table is composed of at least two frame units with upper and lower umbrella-type frames. It features that at the connection position of two adjacent units, the top ends of the relative supporting rods for adjacent upper frames are hinged and the bottom ends of the relative supporting rods for adjacent lower frames are hinged. Its advantages are high structural firmness and large table top supported by it.

Description

technical field [0001] The invention belongs to a support frame of a folding table. Background technique [0002] The four sides of the existing folding table support frame are usually composed of X-shaped brackets formed by cross-hinged connection of two support rods. The legs cannot be stretched under the table, affecting its comfort. And its strength is not high enough, 002394901 patent discloses a kind of folding table support frame that is made up of upper and lower umbrella frame type supports, the support frame side of this structure has retractable space, can make the people sitting next to it more comfortable , the disadvantage is that the desktop supported by it is small, and if the length of the support rod is simply lengthened, the strength of the support frame will be reduced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a support frame for a folding table that can increase the area for supporti...
