They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following is combined with Figure 1-7 The utility model is further described.

[0025] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a rewinding device for a scroll.

[0026] The specific technical solution includes a reel 1, a reel 2, a limiting component, and a rotating component.

[0027] A further design is as follows: an opening is provided at the bottom of the reel 1 for passing the spread 3, and the reel 2 is rotatably arranged inside the reel 1, the outside of the reel 2 is fixedly connected with the spread 3, and the spread 3 extends to the outside of the reel 1 through the opening.

[0028] Among them, in order to increase stability, two support plates 4 are fixedly connected inside the reel 1, and the reel 2 passes through and is rotatably connected to the support plates 4. In order to prevent the spread 3 from being completely wound into the reel 1, a blocking rod is fixedly connected to the bottom end of the spread 3, and the blocking rod is used to block the opening at the bottom of the reel 1.

[0029] In this embodiment, the limiting component is used to limit the position of the reel 2 when the spread 3 is pulled out;

[0030] Specifically, the limiting component includes a rotating column 10 rotatably connected to one end of the outer side of the reel 1, a fixing ring 6 fixedly connected to one end of the outer side of the reel 1, multiple sets of bevel teeth 11 fixedly connected to the inner wall of the fixing ring 6, and an inclined plate 14 slidably arranged in the rotating column 10.

[0031] Among them, the rotating column 10 is coaxially fixedly connected with the reel 2, and a mounting groove 12 is provided on the outside of the rotating column 10. A reset spring 13 is fixedly connected in the mounting groove 12. One end of the reset spring 13 is fixedly connected to the inclined plate 14. The inclined tooth 11 is a right-angled triangle structure, and the inclined plate 14 is a trapezoidal structure, which is similar to the ratchet principle. The rotating column 10 can only rotate unidirectionally counterclockwise (unless the inclined plate 14 is no longer engaged with the inclined tooth 11).

[0032] The explanation is as follows: pulling the baffle bar downward drives the spreader 3 to unfold downward, and then during the unfolding process of the spreader 3, the reel 2 will be driven to rotate, and the reel 2 will drive the spiral spring 5 to be subjected to spiral force; therefore, under the elastic force of the reset spring 13, the inclined plate 14 will continuously engage between the two inclined teeth 11, and at the same time, through the resistance of the side walls of the inclined teeth 11 to the inclined plate 14, the rotating column 10 and the reel 2 can only rotate unidirectionally counterclockwise, so that the spreader 3 can be pulled and unfolded to any position to stop.

[0033] In order to automatically reel in the spread 3, a rotating assembly is provided to allow the reel 2 to automatically rotate and wind the spread 3 when the limiting assembly is no longer limiting the reel 2.

[0034] Among them, the rotating component is a spiral spring 5 arranged on one side of the inner part of the reel 1, one end of the reel 2 passes through the spiral spring 5 and is fixedly connected to one end of the spiral spring 5, and the outer end of the spiral spring 5 is fixedly connected to the inner wall of the reel 1, and the spiral spring 5 is used to drive the reel 2 to rotate automatically.

[0035] Specifically, the outside of the fixed ring 6 is also rotatably connected to the rotating ring 7, the inside of the rotating column 10 is provided with a guide groove 15, the outer wall of the inclined plate 14 is fixedly connected to the pull rope 9, one end of the pull rope 9 passes through the guide groove 15 and is fixedly connected to the rotating ring 7, the outside of the fixed ring 6 is also fixedly connected to the guide rod 8, the guide rod 8 is located inside the rotating ring 7, the pull rope 9 passes through the guide rod 8 and is fixedly connected to the rotating ring 7, if it is necessary to roll up the spread 3 for carrying, just rotate the rotating ring 7 counterclockwise, let the rotating ring 7 pull the pull rope 9, let the pull rope 9 pull the inclined plate 14 to slide until the inclined plate 14 is no longer stuck between the two bevel teeth 11, and then under the elastic force of the spiral spring 5, the elastic force can be released to allow the reel 2 to rotate, so that the spread 3 is wound around the outside of the reel 2.

[0036] In order for those skilled in the art to fully understand the technical solution, the utility model makes the following overall summary:

[0037] In the initial state, the spread 3 is wound on the reel 2;

[0038] When it is necessary to pull it out, just pull the stop rod downward to drive the spreader 3 to unfold downward, and then during the unfolding process of the spreader 3, the reel 2 will be driven to rotate, and the reel 2 will drive the volute spring 5 to be volute-loaded;

[0039] In addition, the reel 2 will also drive the rotating column 10 to rotate counterclockwise, see the attached Figure 5 As shown in;

[0040] Therefore, under the elastic force of the return spring 13, the inclined plate 14 will be constantly engaged between the two inclined teeth 11, and at the same time, the side wall of the inclined teeth 11 will resist the inclined plate 14, so that the rotating column 10 and the reel 2 can only rotate counterclockwise in one direction (consistent with the ratchet principle), so that the spread 3 can be pulled and unfolded to any position to stop;

[0041] If you need to roll up the spread 3 for carrying, please refer to the attached Figure 4 , just rotate the rotating ring 7 counterclockwise, let the rotating ring 7 pull the pull rope 9, let the pull rope 9 pull the inclined plate 14 to slide until the inclined plate 14 is no longer stuck between the two inclined teeth 11;

[0042] Then, under the elastic force of the spiral spring 5 , the elastic force can be released to allow the reel 2 to rotate, thereby winding the spread 3 around the outside of the reel 2 .

[0043] Therefore, in the utility model, the display cloth 3 can be conveniently pulled out and displayed at any position, and the display cloth 3 can also be automatically wound around the reel 2 inside the reel 1 for carrying without being loose.

[0044] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
