[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4The screen door with adjustable rewinding speed comprises a screen door box 1, a screen door frame 2 and a yarn reel 3; the screen door box 1 is located at one side of the screen door frame 2, and both ends of the screen door box 1 are connected to both ends of the screen door frame 2; both ends of the screen door box 1 are provided with speed regulating turbine devices 11; the yarn reel 3 is located in the screen door box 1, and both ends of the yarn reel 3 are connected to the speed regulating turbine device 11; the speed regulating turbine device 11 comprises a speed regulating rod 111 and a gear 112; one end of the speed regulating rod 111 is provided with a spiral pattern, and one end of the speed regulating rod 111 is against the gear 112; the other end of the speed regulating rod 111 is connected with the external bolts of the screen door box 1.

[0028] Specifically, when the user needs to adjust the rebound speed of the screen door to be slower, the other end of the speed regulating rod 111 is rotated clockwise to change the area of ​​the one end of the speed regulating rod 111 against the gear 112, thereby changing the rotation speed of the gear 112 to be slower; when the user needs to adjust the rebound speed of the screen door to be faster, the other end of the speed regulating rod 111 is rotated counterclockwise to change the area of ​​the one end of the speed regulating rod 111 against the gear 112, thereby changing the rotation speed of the gear 112 to be faster.

[0029] A connector is provided between the screen door box 1 and one side of the screen door frame 2, and the screen door box 1 and the screen door frame 2 are assembled and connected through the connector, so that the screen door box 1 can be detachably installed on one side of the screen door frame 2, which is convenient for users to install and disassemble the product.

[0030] Furthermore, one end of the yarn reel 3 is connected to the gear 112 .

[0031] Specifically, since one end of the yarn reel 3 is connected to the gear 112, when the rotation speed of the gear 112 is slower, the yarn reel 3 follows the gear 112, so that the rotation speed of the yarn reel 3 slows down; when the rotation speed of the gear 112 is faster, the yarn reel 3 follows the gear 112, so that the rotation speed of the yarn reel 3 speeds up.

[0032] Furthermore, the top and bottom of the screen door frame 2 are both provided with slide grooves 201 , and the screen door with adjustable rewinding speed also includes a handrail 4 ; the handrail 4 is located on the slide groove 201 , and the handrail 4 is slidably connected to the slide groove 201 .

[0033] Specifically, a gauze net is provided on the gauze drum 3, one end of the gauze net is connected to one side of the gauze drum 3, and the other end of the gauze net is connected to the handrail 4; when the rotation speed of the gauze drum 3 slows down, the speed at which the gauze net and the handrail 4 slide on the slide groove 201 slows down; when the rotation speed of the gauze drum 3 speeds up, the speed at which the gauze net and the handrail 4 slide on the slide groove 201 speeds up.

[0034] A slide rail structure is provided on the slide groove 201, and the handrail 4 is slidably connected on the slide rail structure, so that the handrail 4 together with the gauze can remain stable during the sliding process, and the sliding process is smooth.

[0035] Furthermore, a wire control structure is provided on the handrail 4 , and the wire control structure is slidably connected to the slide groove 201 .

[0036] Specifically, when the user pushes or pulls the handrail 4 to a certain position of the slide groove 201 , the gauze stops following the handrail 4 due to the control of the wire control structure, so that the handrail 4 can stay at any position of the slide groove 201 .

[0037] Furthermore, rebound devices are provided inside both ends of the yarn reel 3; the rebound device includes a spring seat 31, a spring tube 32 and a tension spring member 33; one end of the spring tube 32 is sleeved on the spring seat 31, and the other end of the spring tube 32 is sleeved on the tension spring member 33.

[0038] Furthermore, a spring is provided in the spring tube 32 ; one end of the spring is connected to the spring seat 31 , and the other end of the spring is connected to the tension spring member 33 .

[0039] Specifically, one end of the spring is connected to the spring seat 31, and the other end of the spring is connected to the tension spring member 33, so that the spring is straightened and generates a certain elastic force.

[0040] When the other end of the gauze mesh moves away from the yarn reel 3, the spring in the spring tube 32 is deformed; when the gauze mesh shrinks back to the yarn reel 3, the spring in the spring tube 32 is restored to its original shape, causing the yarn reel 3 to rotate, thereby causing the other end of the gauze mesh to move toward the yarn reel 3, and the gauze mesh is rotated and sleeved on the yarn reel 3.

[0041] The utility model provides a screen door with adjustable rewinding speed. When the user needs to adjust the rebound speed of the screen door to be slower, the other end of the speed regulating rod 111 is rotated clockwise to change the area of ​​the abutment between one end of the speed regulating rod 111 and the gear 112, thereby changing the rotation speed of the yarn reel 3 to be slower; when the user needs to adjust the rebound speed of the screen door to be faster, the other end of the speed regulating rod 111 is rotated counterclockwise to change the area of ​​the abutment between one end of the speed regulating rod 111 and the gear 112, thereby changing the rotation speed of the yarn reel 3 to be faster.

[0042] In addition, the above is a detailed introduction to the screen door with adjustable rewinding speed provided by the embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. At the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
