[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 3The utility model provides an embodiment: an automatically unfolded roll-up display stand, including a protective shell 1, which is usually designed to protect the internal structure to prevent the internal structure from being damaged, resulting in the failure of the entire device. The protective shell 1 is fixedly connected to a hydraulic cylinder 2 inside, through which the subsequent workpiece can be pushed, and the driving end of the hydraulic cylinder 2 is fixedly connected to a push rod 3, and both sides of the front end of the push rod 3 are rotatably connected to a rotating rod 4, and the push rod 3 can be pushed forward by the hydraulic cylinder 2, so that the rotating rod 4 can be expanded to both sides, and the front end of the rotating rod 4 is rotatably connected to a sliding rod 5, and when the rotating rod 4 is expanded, the sliding rod 5 can be driven to move, and the two sliding rods 5 are slidably connected to a connecting rod 6 at one end close to the inside, and the left and right sides of the connecting rod 6 are fixedly connected to the outside of the limiting ring 7, and when the sliding rod 5 moves, the limiting ring 7 sleeved on the outside of the connecting rod 6 prevents the sliding rod 5 from separating, so that the sliding rod 5 can be unfolded.

[0033] The outer part of the limit ring 7 is slidably connected to the inner wall of the slide bar 5, and the movement process of the limit ring 7 can be limited by the slide bar 5. The top of the protective shell 1 is fixedly connected with a stabilizing rod 8, and the protective shell 1 can provide a fixing source for the stabilizing rod 8. The front end of the stabilizing rod 8 is fixedly connected to two supporting rods 9, and the stabilizing rod 8 can support the supporting rod 9 to prevent collapse when supporting subsequent workpieces. The bottoms of the two supporting rods 9 are fixedly connected to the tops of the two slide bars 5. At the same time, the slide bar 5 can drive the two supporting rods 9 to move, and the two supporting rods 9 are rotatably connected.

[0034] The front ends of two sliding rods 5 are fixedly connected with a disassembly component, which is used to facilitate the picking up and placing of subsequent workpieces. The disassembly component includes two connecting shells 10. The connecting shells 10 are for accommodating and fixing subsequent workpieces or components to facilitate disassembly and installation operations. Universal wheels are fixedly connected to the bottoms of the protective shell 1 and the two connecting shells 10. The function of the universal wheels is to provide additional protection and support, and the presence of the universal wheels can make the entire device move more flexibly in different directions. The rear ends of the two connecting shells 10 are fixedly connected to the front ends of the sliding rods 5. The sliding rods 5 can provide a fixed source for the connecting shells 10. An arc-shaped block 11 is fixedly connected to the inner top of the connecting shell 10. A telescopic rod 12 is fixedly connected to the bottom of the connecting shell 10. A strong spring 13 is sleeved outside the telescopic rod 12. The telescopic rod 12 and the strong spring 13 can relieve pressure on subsequent workpieces. The top of the telescopic rod 12 is fixedly connected with a support block 14. The pressure received is transmitted to the telescopic rod 12 through the support block 14. One end of the strong spring 13 is fixedly connected to one side of the connecting shell 10. The connecting shell 10 provides an effect for the strong spring 13 to buffer and relieve force. The other end of the strong spring 13 is fixedly connected to one side of the support block 14. The support block 14 is a component that provides pressure for the strong spring 13. A clamping block 15 is fixedly connected to the top of the support block 14. The support block 14 can fix the clamping block 15 to provide a stable support source. A winding device 22 is fixedly connected to the adjacent ends of the arc-shaped block 11 and the clamping block 15.

[0035] Referring to Figure 3 - Figure 5 , the winding device 22 can be clamped and fixed by the arc-shaped block 11 and the clamping block 15, which is convenient for picking up and installing. A rotating rod 16 is rotatably connected inside the winding device 22. Torque springs 17 are fixedly connected to both the left and right sides of the rotating rod 16. When the rotating rod 16 rotates, it can drive the torque springs 17 to wind. Connecting blocks 18 are fixedly connected to the inner parts of the left and right sides of the winding device 22. One end of the torque spring 17 is fixedly connected to the outside of the connecting block 18. The connecting block 18 provides a support point and a force-receiving point for the winding device 22. A curtain 19 is fixedly connected to the outside of the rotating rod 16. The outside of the curtain 19 is in contact with the opening of the winding device 22. The curtain 19 can be pulled through the opening of the winding device 22. By rotating the rotating rod 16, the curtain 19 can be pulled and wound to achieve the effect of quick picking up and quick placing;

[0036] At the top of the two support rods 9, there is a fixed connection with a cross bar 20. The cross bar 20 can provide a support source for subsequent workpieces. The cross bar 20 is fixed by bolts. When different sizes of curtain 19 are needed, the cross bar 20 can be adjusted. The outside of the cross bar 20 is fixedly connected with clips 21. The inside of the clips 21 is fixedly connected to the front and rear ends of the curtain 19. Fixing the curtain 19 through the clips 21 is designed for convenient taking, so as to achieve the display effect.

[0037] Working principle: When the device is positioned, by starting the hydraulic cylinder 2, the push rod 3 is pushed to move forward, and at the same time, the two rotating rods 4 can be expanded outward to pull the two sliding rods 5. The limit rings 7 fixed to the outside of both sides of the connecting rod 6 are designed to prevent excessive pulling and the connecting rod 6 from detaching from the inside of the two sliding rods 5, so as to achieve the effect of the display rack unfolding.

[0038] When the device is adjusted to the desired width, the winder 22 is placed inside the arc-shaped block 11 and the clamping block 15. When the width of the winder 22 is too large, by squeezing the clamping block 15 and the support block 14, the telescopic rod 12 and the strong spring 13 can be telescoped to adapt to the size of the winder 22, which can not only facilitate taking but also facilitate installation. The curtain 19 fixed by the rotating rod 16 can be pulled. When the curtain 19 is pulled, the torsion spring 17 contracts to generate potential energy. When the curtain 19 is pulled onto the cross bar 20, the curtain 19 can be clamped by the clips 21, so as to achieve the display effect.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
