[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides the following technical solution:

[0022] Please see Figures 1-4 A folding connecting device for a display case includes two movable plates 1, with multiple first display plates 2 and second display plates 3 arranged between the movable plates 1. The first display plates 2 are fixedly connected to the surface of the movable plate 1 on the left, and the second display plates 3 are fixedly connected to the surface of the movable plate 1 on the right. A storage groove 4 is provided on the right side of the first display plate 2, and one side of the second display plate 3 extends into the interior of the storage groove 4 and is slidably connected to the inner wall of the storage groove 4. Fixing plates 5 are fixed above and below the opposing surfaces of the movable plates 1, and fixing grooves 6 are provided on the opposing surfaces of the fixing plates 5. A connecting plate 7 is arranged between the fixing plates 5, and the connecting plate 7 extends into the interior of the fixing groove 6 and is slidably connected to the inner wall of the fixing groove 6. An installation groove 8 is provided on the surface of the connecting plate 7, and an adjustment structure 9 is provided inside the installation groove 8. A fixing frame 10 is fixed below one surface of the movable plate 1, and a lifting structure 11 is movably connected inside the fixing frame 10. Rollers 12 are fixed on both the front and rear sides of the bottom of the lifting structure 11.

[0023] The adjustment structure 9 includes a bidirectional cylinder 91, a connecting rod 92, a push-pull rod 93, and a connecting block 94. The bidirectional cylinder 91 is fixed inside the mounting groove 8. The connecting rod 92 is located on the front and rear sides of the connecting plate 7, and the output shafts on the front and rear sides of the bidirectional cylinder 91 extend to the outside of the mounting groove 8 and are fixedly connected to the connecting rod 92. The push-pull rod 93 is hinged to the left and right ends of the connecting rod 92. The connecting block 94 is fixed to the front and rear sides of the opposite side surface of the fixing plate 5. The push-pull rod 93 is inclined, and the end of the push-pull rod 93 away from the connecting rod 92 is hinged to the surface of the connecting block 94. When the display case is folded and retracted, the bidirectional cylinders 91 on the upper and lower sides can be opened, causing the connecting rod 92 to move in the front and back direction. The push-pull rods 93 on both sides will then move, pushing the connecting block 94 to move, thereby causing the fixing plates 5 on both sides to move in opposite directions, so that the display case can be folded and adjusted according to the needs of the staff.

[0024] Guide grooves 13 are provided on both the front and rear sides of the inner wall of the fixing groove 6. Guide wheels 14 are rotatably connected to the left and right sides of the front and rear of the connecting plate 7. The guide wheels 14 are located inside the guide grooves 13 and are rolled in connection with the inner wall of the guide grooves 13. When the push-pull rod 93 pushes the connecting block 94 to move, causing the fixing plates 5 on the left and right sides to move, the guide wheels 14 also roll inside the guide grooves 13, increasing the stability of the display box when it is folded and adjusted.

[0025] The lifting structure 11 includes a lifting plate 111, a threaded sleeve 112, a threaded rod 113, a crank 114, and a support plate 115. The lifting plate 111 is slidably connected to the lower part of the fixed frame 10. The threaded sleeve 112 is embedded in the middle of the lifting plate 111 and is fixedly connected to the lifting plate 111. The threaded rod 113 is disposed through the upper part of the fixed frame 10 and is rotatably connected to the fixed frame 10. The threaded rod 113 is threadedly connected to the inner wall of the threaded sleeve 112. The crank 114 is fixed to the top of the threaded rod 113. The support plate 115 is fixed below one side surface of the movable plate 1 and located inside the fixed frame 10. The bottom end of the threaded rod 113 is rotatably connected to the top of the support plate 115. The roller 12 and... The top of the lifting plate 111 is fixedly connected, and the front and rear sides of the inner wall of the fixed frame 10 are provided with limit grooves 16. The front and rear sides of the top of the lifting plate 111 are fixed with limit plates 17. One side of the limit plate 17 extends into the interior of the limit groove 16 and slides in connection with the inner wall of the limit groove 16. When the display box is folded, the staff needs to rotate the cranks 114 on both sides in advance, so that the threaded rod 113 rotates, causing the lifting plate 111 to move up and down on the surface of the threaded rod 113. The lifting plate 111 is controlled to move the roller 12 out of the interior of the fixed frame 10, so that the roller 12 supports the movable plate 1. When the display box is folded and retracted, the roller 12 will roll on the ground, which is convenient for adjustment.

[0026] Guide strips 15 are fixed on the upper right side of the first display panel 2, and the surface above the guide strips 15 is inclined. When the display box is folded, the second display panel 3 will enter the storage slot 4. The goods on the surface of the second display panel 3 can be guided by the guide strips 15 to move to the surface of the first display panel 2, so as to avoid the first display panel 2 squeezing the goods on the surface of the second display panel 3 and damaging the goods.

[0027] Its working principle is as follows:

[0028] When the staff needs to fold and adjust the display case, they first rotate the cranks 114 on both sides, causing the lifting plate 111 to descend and the roller 12 to move out of the fixed frame 10. Then, the staff can open the bidirectional cylinder 91 inside the mounting slot 8, causing the connecting rod 92 to move. The connecting block 94 pushes the fixed plates 5 on both sides to move, causing the fixed plates 5 on both sides to move in opposite directions. The second display plate 3 between the movable plates 1 also slides inside the storage slot 4 to adjust the display case as a whole. After adjusting the display case to the appropriate position, the staff can rotate the cranks 114 on both sides again, causing the roller 12 to return to the fixed frame 10, thus completing the folding and adjustment operation of the display case.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
