[0025] like Figure 1 - Figure 7 As shown, a foldable display frame structure in the utility model is similar to the existing foldable display frame structure, such as a foldable display frame for promotion disclosed in the patent with announcement number CN219143742U. The main improvement of the utility model is that the user can open the two foldable frames 1 at a certain angle, so as to display in the front and back directions, thereby improving the publicity effect of the advertisement. Figures 1 to 7 As shown, when the foldable display frame structure of the present invention is used, first, the two advertising pictures are reinforced and fixed on the inner sides of the two frames 1 by the clamping mechanism, and the pictures are facing outwards to facilitate the display of the advertising pictures. Then, the fastening bolts 6 are loosened, and the arc-shaped slider 5 can slide in the flip slide groove 401 on the folding disc 4 at this time, so that the two frames 1 can be flipped at an angle. When the angle is appropriate, the fastening bolts 6 are screwed into the threaded holes 501, thereby driving the threaded caps of the fastening bolts 6 to abut against the outer wall of the folding disc 4, connecting and fixing the arc-shaped slider 5 and the folding disc 4, so that the angle between the two frames 1 is fixed. Then, the two fixed frames 1 are placed on the ground or on a display cabinet, and the advertisements on the front and back sides can be displayed, thereby increasing the display range of the display frame and improving the display effect.

[0026] like Figure 1 - Figure 3 As shown, the two sections of the arc-shaped slider 5 are flush with the two sides adjacent to the crossbar 2, and the two sections of the flip chute 401 are flush with the two sides adjacent to the crossbar 2. The two sections of the arc-shaped slider 5 are designed to be flush with the two sides of the fixed crossbar 2, and the two sections of the flip chute 401 can be used to fold and merge the two frames 1 for easy storage, and can be flipped to form a whole horizontal frame 1, so that a larger picture of advertising can be carried out.

[0027] like Figure 1 - Figure 7 As shown, the clamping mechanism includes a connecting plate 7 and a clamping block 8. One end of the connecting plate 7 is fixedly connected to one end of the crossbar 2, and the other end is connected to the vertical bar 3. Two symmetrically arranged flipping blocks 9 are fixedly connected to the inner side of the connecting plate 7. The adjacent sides of the two flipping blocks 9 are provided with flipping grooves 901. The two sides of the clamping block 8 are respectively rotatably connected to the two flipping grooves 901 through a rotating shaft. The two flipping grooves 901 are fixedly connected with a torsion spring 10. The other ends of the two torsion springs 10 are respectively fixedly connected to the rotating shafts on both sides of the clamping block 8. When the advertising canvas is installed on the frame 1 using the clamping mechanism, the clamping block 8 can be opened outward between the two flipping blocks 9, and a corner of the advertising cloth can be placed between the clamping block 8 and the connecting plate 7. Then, the clamping block 8 is released, and the rotating shafts on both sides of the clamping block 8 are driven by the torsion spring 10 to reset the clamping block 8 inward, and the advertising cloth is clamped on the connecting plate 7. The other triangle of the advertising cloth is connected and fixed to the clamping mechanism of the other triangle of the frame 1 in the same way, and the installation and fixation of the advertising cloth on the frame 1 can be completed.

[0028] like Figure 1 - Figure 7 As shown, the vertical rod 3 includes a telescopic tube 11 and an extension rod 12, the outer wall of the extension rod 12 is slidably connected to the inner wall of the telescopic tube 11, the ends of the telescopic tube 11 and the extension rod 12 that are away from each other are fixedly connected to the ends of the two adjacent connecting plates 7 that are away from the cross bar 2, and the side wall of the telescopic tube 11 close to the end of the extension rod 12 is connected with a hand screw 13, the threaded rod of the hand screw 13 penetrates the telescopic tube 11 and abuts against the outer wall of the extension rod 12, and the threaded rod of the hand screw 13 is threadedly connected to the telescopic tube 11. When installing a longer advertising cloth, the extension rod 12 can be pulled out of the telescopic tube 11 for a certain length, and then when it is at a suitable length, the hand screw 13 is screwed inwardly and the threaded rod is abutted against the inner extension rod 12, so that the extension rod 12 is fixed to the inner wall of the telescopic tube 11, and the length adjustment of the vertical rod 3 is completed.

[0029] like Figure 1 - Figure 7 As shown, the cross-sections of the telescopic tube 11 and the extension rod 12 are both L-shaped structures, the side of the connecting plate 7 away from the clamping block 8 is flush with the side of the cross bar 2 and the telescopic tube 11 facing outward, and the side of the clamping block 8 away from the connecting plate 7 is flush with the side of the cross bar 2 and the telescopic tube 11 facing inward. The telescopic tube 11 and the extension rod 12 are designed as L-shaped structures, so that the corners of the advertising cloth can be attached to the inner side of the L-shaped structure after clamping and installation, avoiding the two sides of the advertising cloth from being scattered due to misalignment, and at the same time, the outer side of the clamping mechanism is flush with the inner side of the cross bar 2, so that the two frames 1 are more closely fitted when folded and merged, and the storage is more neat.

[0030] like Figure 1 - Figure 7As shown, a non-slip pad is provided on one side of the clamping block 8 close to the connecting plate 7. The non-slip pad is installed on the inner side of the clamping block 8 to increase the contact friction when the advertising cloth is clamped and fixed, and prevent the advertising cloth from slipping.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
