Description

Center-sagging-prevention scroll and windproof sunshade curtain Technical Field The utility model relates to a scroll, in particular to a scroll capable of preventing central sagging and a windproof sunshade curtain. Background The curtain is made of cloth, hemp, yarn, aluminum sheet, wood sheet, metal material, etc. and has the functions of shading sun, insulating heat and regulating indoor light. The cloth curtain is divided into cotton gauze, polyester cloth, polyester cotton blending, cotton-flax blending, non-woven fabrics and the like according to materials, and different materials, textures, colors, patterns and the like are combined to form different styles of cloth curtains to be matched with indoor design curtains of different styles. In the prior art, the electric curtain is widely applied, and the electric curtain is generally installed indoors or outdoors and is used for sun shading, wind proofing and the like. In some use scenes of large stripping or large width, for example, width of 5 meters, 10 meters or even larger, ultra-wide curtains are required to be used, if the corresponding length is adopted, the rolling and unwinding reel of the curtains can be caused to be bent downwards due to dead weight and gravity of the curtains, so that the curtains can not be normally used or have poor use effects, especially long and wide curtains, the reel also adopts an ultra-long structure, no matter the reel is hollow or solid, the weight and the length ratio are basically consistent, the sagging problem can occur in the middle, the sagging of the middle part of the reel can be caused, the reel can be caused to be in an arc structure with low middle and high two ends, thus the problem that the middle of the curtains (rolling curtains) rolled on the reel is thick and the two sides are thin can be caused when the curtains (rolling curtains) are rolled up towards the middle, the attractiveness is extremely bad, and the reel can be greatly rocked when the curtains are rolled and blown outdoors. In order to solve the technical problem, for example, the application number "201921281861.6", the patent name "an ultra-wide electric curtain installation structure", the middle part of the winding and unwinding reel is provided with a middle plate for supporting the same, so that the center is prevented from sagging, and the structure is equivalent to dividing one reel into two reels, namely, the supporting points are added. In this structure, when in actual use, the connecting zipper in the middle may have a clamping stagnation problem when being wound and unwound. When in actual use, especially when outdoor pergola uses, when outdoor strong wind, the connection zip fastener in the middle is easy to damage, leads to actual result of use not good. Therefore, in the existing structure, it is difficult to realize the ultra-wide sunshade curtain, the roll shaft with the length exceeding 6m is general, and the central sagging amplitude is larger, so that the ultra-wide sunshade curtain generally cannot exceed 6m (the ultra-wide sunshade curtain is actually required to be particularly wide, and is generally spliced by a plurality of sunshade curtains, and a whole sunshade curtain cannot be realized). If special steel is adopted, the cost is extremely high, the consumer acceptance is extremely low, and the practicability is poor. Disclosure of Invention The utility model aims to provide a central sagging prevention scroll and a windproof sunshade curtain, which can effectively prevent the sagging of the scroll and improve the strength of the scroll by using the structure. In order to achieve the aim, the technical scheme adopted by the utility model is that the reel capable of preventing the central sagging comprises a reel and a supporting shaft, wherein the reel is of a hollow structure and is rotatably sleeved on the supporting shaft; the middle part of the support shaft is provided with an upward bending part, the bending part is rotatably provided with a support component, and the top of the support component is propped against the inner wall of the scroll. In the above technical scheme, the supporting component is rotatably connected with the bending part, the supporting component is a ball, a roller or a swivel, and the top outer surface of the ball, the roller or the swivel is propped against the inner wall of the scroll. In the technical scheme, an intermediate pipe is sleeved between the supporting shaft and the scroll, and the top of the supporting part is propped against the top surface of the inner wall of the intermediate pipe; and/or, the outer surface of the scroll is also provided with a clamping groove extending along the axis direction of the scroll. In the technical scheme, the outer surfaces of the two ends of the middle pipe are annularly provided with the plurality of supporting pieces, and the outer edges of the supporting pieces are propped against the inner wall of the scroll. In the above tech
