DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0032] like Figure 1-9 The present embodiment shows a storage type polyester cloth unfolding device, through which the polyester cloth can be spread out for display. The unfolding device includes a bottom support body 1, a lower support column 6, a cover body 2, an upper support column 7, and a cloth assembly. The bottom support body 1 has a designed length, which is greater than the width of the polyester cloth. The bottom support body 1 can be welded from metal plates or made of plastic. A storage cavity 11 with an open top is processed on the bottom support body 1. The length of the storage cavity 11 is greater than the width of the polyester cloth. The aforementioned cover body 2 is a plate structure, which has a closed state covering the opening of the storage cavity 11 and a separated state upwardly away from the bottom support body 1. In the closed state, the opening of the storage cavity 11 is closed, so that dust in the air can be prevented from entering the storage cavity 11. The two sides of the aforementioned bottom support body 1 in the width direction of the storage cavity 11 are formed by a top plate. When the cover body 2 is in the closed state and the separated state, a receiving space 8 with a vertical spacing is formed between the cover body 2 and the top plate. The receiving space 8 is located outside the receiving cavity 11 and extends along the length direction of the bottom support body 1 .

[0033] The aforementioned cloth assembly is arranged in the storage cavity 11, and the cloth assembly includes a cloth roller 3 and a cloth body 4 wound on the cloth roller 3. In the present embodiment, the cloth body 4 is preferably polyester cloth. A connection position is arranged on the cover body 2, so that the end of the cloth body 4 away from the cloth roller 3 is connected to the cover body 2 through the connection position. In the present embodiment, one end of the cloth body 4 and the cover body 2 can be fixed by screws, adhesives, Velcro and the like in the prior art. Through the above-mentioned structural design, when the cover body 2 is in the closed state, the cloth body 4 can be wound on the cloth roller 3. When the cover body 2 is in the separated state, the cloth body 4 can be pulled and driven to move out of the storage cavity 11.

[0034] In this embodiment, the aforementioned lower support columns 6 have a designed length, which are arranged on both sides in the length direction of the bottom support body 1. Two groups of lower support columns 6 are arranged side by side on each side. The lower support columns 6 on the same side are connected by a lower connecting rod 61. The lower connecting rod 61 is inserted into the lower assembly hole on the bottom support body 1 so that the lower support column 6 can be rotatably connected to the bottom support body 1, thereby having an unfolded state and a folded state. Among them, the central axis of the lower assembly hole extends along the width direction of the bottom support body 1, so that the lower support columns 6 on both sides rotate toward the relative inner side to form a folded state, and the lower support columns 6 on both sides rotate toward the relative outer side to form an unfolded state.

[0035] The aforementioned upper support column 7 has a designed length, which is arranged corresponding to the lower support column 6. The upper support columns 7 are arranged on both sides in the length direction of the cover body 2. Two groups of upper support columns 7 are arranged side by side on each side. The upper support columns 7 on the same side are connected by an upper connecting rod 71. The upper connecting rod 71 is inserted into the upper assembly hole on the cover body 2 so that the upper support column 7 can be rotatably connected to the cover body 2, thereby having an unfolded state and a folded state. Among them, the central axis of the upper assembly hole extends along the width direction of the bottom support body 1, so that the upper support columns 7 on both sides rotate toward the relative inner side to form a folded state, and the upper support columns 7 on both sides rotate toward the relative outer side to form an unfolded state.

[0036] Through the above structural design, in the aforementioned folded state, the upper support column 7 and the lower support column 6 can be stored in the receiving space 8. In the aforementioned unfolded state, the upper support column 7 and the lower support column 6 are both arranged vertically, and the upper support column 7 has a bottom end facing downward, and the lower support column 6 has a top end facing upward. In the aforementioned unfolded state and separated state, the upper support column 7 and the lower support column 6 have an assembly state of mutual plug-in cooperation at corresponding positions, and the upper support column 7 and the lower support column 6 are mutually plugged in to form support for the cover body 2 in the separated state. A support position is arranged on the aforementioned lower support column 6. When the lower support column 6 is in the unfolded state, the support position abuts against the bottom support body 1 up and down. Through the upper and lower abutment of the support position with the bottom support body 1, the rotation of the lower support column 6 is restricted, so that the lower support column 6 forms a stable and effective support. In this embodiment, the above support position is arranged on the aforementioned lower connecting rod 61. A support pad 5 is fixedly installed on the lower support column 6 at the support position. When the lower support column 6 is in the unfolded state, the support cushion block 5 abuts against the bottom support body 1 from top to bottom. The support cushion block 5 is preferably a rubber block.

[0037] In this embodiment, a plug-in tube body 62 is fixedly mounted on one end of the aforementioned lower support column 6, and a plug-in channel is formed inside the plug-in tube body 62. In the aforementioned assembly state, one end of the upper support column 7 is inserted into the plug-in channel of the plug-in tube body 62 to form an upper and lower plug-in fit with the plug-in tube body 62. The inner diameter of the plug-in channel of the plug-in tube body 62 is matched with the outer diameter of the upper support column 7, so that the upper support column 7 will not shake significantly after being plugged in.

[0038] In this embodiment, vertical grooves 12 are processed on the side walls on the opposite sides in the length direction of the storage chamber 11. The vertical groove 12 is a U-shaped groove. The top of the vertical groove 12 is open and the bottom is closed. The two ends of the cloth roller 3 are movably arranged in the vertical groove 12. Through the above-mentioned structural design, the cloth roller 3 can move up and down in the bottom support body 1. When the upper support column 7 and the lower support column 6 are assembled, the cloth roller 3 can be suspended in the vertical groove 12, and the cloth is unfolded between the cover body 2 and the cloth roller 3. The cloth roller 3 uses its own gravity to pull the polyester cloth downward to improve the flatness of the polyester cloth when it is unfolded, which is highly practical. One end or both ends of the aforementioned cloth roller 3 are located outside the storage chamber 11 according to the rotating handle 31. When the cover body 2 is in the closed state, the cloth roller 3 is received by the bottom of the vertical groove 12, and the cloth roller 3 is rotated by rotating the handle 31, so that the cloth body 4 can be rolled up on the cloth roller 3.

[0039] In the above structural design, the fabric assembly is arranged in the bottom support body 1 to increase the overall weight of the bottom support body 1, so that the center of gravity of the entire device moves downward, which is beneficial to improve the stability of the entire device during use and prevent the device from tipping over during display.

[0040] In specific use, when the polyester cloth needs to be displayed, the cover body 2 is opened to switch the cover body 2 to a separated state, and the cloth body 4 is pulled out of the storage cavity 11 along with the cover body 2. The upper support column 7 and the lower support column 6 are switched to an unfolded state, and plugged and matched with each other to support and fix the cover body 2 in a separated state, so that the polyester cloth is unfolded between the cover body 2 and the bottom support body 1. When the cloth does not need to be displayed, the cover body 2 is moved upward so that the upper support column 7 and the lower support column 6 are separated from each other, and then the upper support column 7 and the lower support column 6 are switched to a folded state, and the cover body 2 is covered on the bottom support body 1, so that the upper support column 7 and the lower support column 6 are stored in the storage space 8, and the cloth roller 3 is rotated by rotating the handle 31 to roll the polyester cloth onto the cloth roller 3 and seal it in the storage cavity 11, so that the polyester cloth can be isolated from dust in the air to reduce dust adhesion. The height of the overall structure is reduced by folding, so as to facilitate the carrying and transportation of the entire device, and effectively meet the display requirements of the polyester cloth.
