[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0024] Reference Figure 3-7 As shown, the quick-change fabric device includes a roller 1 and a tarpaulin 2. The roller 1 is composed of a main roller 101 and a secondary roller 102. The secondary roller 102 is detachably installed on the main roller 101. The secondary roller 102 is provided with a groove 10221 for installing the end of the tarpaulin 2. The tarpaulin 2 extends out to the edge of the groove 10221 and is wrapped around the surface of the main roller 101.

[0025] The main roller 101 is a near-circular tube with a recessed area on its surface forming a groove 1011. The two ends of the groove 1011 are arc-shaped transitions to the outer wall of the main roller 101. An extension 1012 is provided on one side of the arc-shaped transition edge, extending from the main roller 101 and hanging into the groove 1011. The extension 1012 is spaced from the bottom wall of the groove 1011, forming a hook cavity 1013.

[0026] The auxiliary roller 102 is installed on the groove 1011 of the main roller 101, and its height does not exceed the circular restriction area where the main roller 101 is located. The auxiliary roller 102 is composed of two parts, including an arc hook 1021 and an open tube 1022 with the groove 10221. The arc hook 1021 is a quarter circle arc. The arc hook 1021 is tangent to the open tube 1022, and the tangent position is located at the opposite end of the groove 10221 on the open tube 1022. The extended end of the arc hook 1021 is embedded in the hook cavity 1013.

[0027] During installation, the end of the arc hook 1021 follows the curved path of the hook cavity 1013 and gradually hooks into the bottom of the hook cavity 1013 at an inclined angle, while the opening tube 1022 is placed on the other side of the groove 1011.

[0028] To ensure the installation of the tarpaulin 2, a fabric-through hole is provided at the end of the tarpaulin 2, and a fabric-through tube passes through it. The end of the tarpaulin 2 with the fabric-through tube is fastened into the groove 10221. The diameter of the fabric-through tube is larger than the opening width of the groove 10221. The fabric-through tube is fastened into the opening tube 1022 through plastic deformation. The opening direction of the groove 10221 is consistent with the opening direction of the groove 1011. The bottom surface of the auxiliary roller 102 is attached to the bottom surface of the groove 1011. At the same time, in order to ensure that the auxiliary roller 102 will not move in the length direction of the main roller 101 after it is installed on the main roller 101, a locking structure that cooperates with the groove 1011 is provided at the part where the opening tube 1022 and the groove 1011 are attached.

[0029] Specifically, the locking structure includes a protrusion a on the opening tube 1022 and a slot b on the bottom wall of the groove 1011. Alternatively, it can be the slot b on the opening tube 1022 and the protrusion a on the bottom wall of the groove 1011. The opening width of the slot b is smaller than the maximum outer diameter of the protrusion a. The protrusion a is embedded into the slot b by the deformation of the slot b, thereby fixing the auxiliary roller 102 on the main roller 101.

[0030] Furthermore, in order to prevent the end of the arc hook 1021 from easily detaching from the hook cavity 1013, a first round end c with a diameter greater than the thickness of the extension 1012 is provided at the end of the extension 1012, and a second round end d is provided at the end of the arc hook 1021.

[0031] Reference Figure 1-2 As shown, a retractable arm awning is provided, which consists of a main body 3 and at least two mounting seats 4 installed on the main body 3. The roller 1 is installed inside the main body 3. Shaft covers 5 are provided on both sides inside the main body 3. The two ends of the main roller 101 are inserted into the bottom walls of the two shaft covers 5. One end of the awning 2 is fixed on the front edge of the main body 3.

[0032] To facilitate the installation and disassembly of the auxiliary roller 102, the length of the auxiliary roller 102 is shorter than that of the main roller 101, and a gap is formed between the two end faces of the auxiliary roller 102 and the two end faces of the main roller 101. The length of the tarpaulin 2 is shorter than that of the auxiliary roller 102, and a gap is formed between the two end faces of the tarpaulin 2 and the two end faces of the auxiliary roller 102.

[0033] During installation or disassembly, the installation position of the auxiliary roller 102 will not interfere with the shaft cover 5. Furthermore, in order to prevent the auxiliary roller 102 from easily detaching from the main roller 101, when the tarpaulin 2 is stretched to its maximum length, it is also necessary to ensure that the tarpaulin 2 covers the groove 1011 on the main roller 101.

[0034] The working process of this utility model is as follows: During installation, firstly, the fabric threading tube is installed at one end of the tarpaulin 2, and the fabric threading tube is fastened into the groove 10221. The arc hook 1021 part on the auxiliary roller 102 is tilted at an angle and extended to the bottom of the hook cavity 1013. Through the cooperation of the protrusion a and the slot b, the auxiliary roller 102 is installed in the groove 1011. The main roller 101 is rotated to wind the tarpaulin 2 onto the main roller 101.

[0035] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
