The organ screen 200 has a first end 210 and a second end 220 arranged oppositely, the first end 210 is fixed to one end of the guide rail 120, and the second end 220 is slidably arranged on the inner frame 110 along the guide rail 120. The pull rod mechanism 300 includes a first pin 310 and a second pin 320, and the first pin 310 and the second pin 320 are arranged oppositely on the second end 220. The wire rope 400 is arranged between the first pin 310, the second pin 320 and the organ screen 200, and is fixed to the frame body 100. The plurality of chrome-plated pin shafts 500 are arranged on the first pin 310 and the second pin 320 respectively, and the chrome-plated pin shafts 500 are arranged on the contact points of the first pin 310, the second pin 320 and the wire rope 400.

[0042] ​The frame body 100 serves as the overall frame structure of the folding screen door 10, providing support and fixing functions. The frame body 100 also provides a mounting base for other components.

[0043] The guide rail 120 is arranged along the first direction of the frame body 100 and is used to guide the sliding of the concertina screen 200. Through the design of the guide rail 120, it is ensured that the concertina screen 200 can move smoothly and accurately during unfolding and folding, avoiding deviation or jamming.

[0044] The first end 210 of the concertina screen 200 is fixed to one end of the guide rail 120, serving as a fixed point to ensure that the screen does not deviate from the track during unfolding and folding.

[0045] The second end 220 of the concertina screen 200 is slidably arranged on the inner frame 110 along the guide rail 120, allowing the screen to stretch and retract as needed. This allows the concertina screen 200 to be layered like an organ, achieving flexible stretching and retracting functions.

[0046] The concertina screen door has good flexibility and flexibility, effectively blocking mosquitoes and dust, and ensuring sufficient indoor light and air circulation.

[0047] The pull rod mechanism 300 has a first pin 310 and a second pin 320 arranged oppositely, and the first pin 310 and the second pin 320 are respectively located on both sides of the second end 220 of the concertina screen 200, serving as a connection and guide. It is used in cooperation with the guide rail 120 to realize the transformation of the unfolding and folding state of the concertina screen 200.

[0048] A plurality of chrome-plated pins 500 are respectively arranged on the first pin 310 and the second pin 320, and are located at the contact points of the pins and the wire rope 400. The chrome-plated pin 500 has a chrome-plated outer circular surface, and the chrome-plated pin 500 contacts the wire rope 400 through the chrome-plated outer circular surface, significantly reducing the frictional resistance, making the pull rod pull more smoothly. Specifically, the surface of the chrome-plated pin 500 is treated by chrome plating, which can significantly reduce the friction coefficient between the chrome-plated pin 500 and the adjacent components and the surface hardness of the components. During use of the folding screen door 10, the chrome-plated pin can smoothly slide in the track or mounting hole, reducing wear caused by friction, thereby prolonging the service life of the screen door.

[0049] The wire rope 400 is arranged between the first pin 310, the second pin 320 and the concertina screen 200, and is fixed to the frame body 100. The main function of the wire rope 400 is to realize the traction and control of the concertina screen 200 through cooperation with the pins.

[0050] The two ends of the wire rope 400 are fixed on the frame body 100, ensuring the stability of the whole system. Through reasonable tension, the wire rope 400 can effectively guide the unfolding and folding actions of the concertina screen 200.

[0051] The present application sets a plurality of chromium-plated pins 500 on the first prong 310 and the second prong 320 and at the contact point with the wire rope 400. Due to the use of the chromium-plated pins 500, the friction coefficient between the prong and the wire rope 400 is reduced, thus the resistance during the overall operation is reduced, making it easier to pull the rod. When the user operates the folding screen door 10, the weight and resistance that the user can feel are both reduced, thus making the screen door feel more light and easy. At the same time, the chromium-plated pins 500 can effectively reduce the wear between the prong and the wire rope 400, because the outer round surface of the chromium-plated pins 500 is harder and more wear-resistant than the outer surface of the prong, the durability of the whole rod mechanism 300 is improved, and the service life of the folding screen door 10 can be extended under the same use conditions.

[0052] Referring to Figure 3 and Figure 4 , according to the folding screen door 10 provided by the present application, the first prong 310 is provided with a first wire passing groove 311 extending in the first direction on the side away from the second prong 320, a first wire passing hole 312 is formed in the first prong 310, the first wire passing groove 311 and the first wire passing hole 312 are in communication with each other, and the chromium-plated pin 500 is arranged at the intersection of the first wire passing groove 311 and the first wire passing hole 312.

[0053] It can be understood that the first wire passing groove 311 is a channel provided on the first prong 310 for the wire rope 400 to pass through. It ensures that the wire rope 400 can move smoothly inside the prong during pulling, while maintaining the correct direction.

[0054] The first wire passing hole 312 is formed in the first prong 310, for the wire rope 400 to pass from one side of the prong to the other side. It is in communication with the first wire passing groove 311, forming a continuous wire rope 400 channel. The first wire passing hole 312 is formed in the first prong 310 and is connected with the first wire passing groove 311, ensuring that the wire rope 400 can pass from one side of the prong to the other side smoothly, maintaining the stretching and contracting function of the screen.

[0055] The chromium-plated pin 500 is arranged at the intersection of the wire passing groove and the wire passing hole, which can effectively convert the friction between the wire rope 400 and the prong into the friction between the chromium-plated pin 500 and the wire rope 400, thus reducing the resistance during operation and reducing the wear on the prong.

[0056] Referring to Figure 3 and Figure 4According to the folding screen door 10, the first mounting hole 313 is arranged on one side of the two opposite sides of the first pin 310 in the direction perpendicular to the first direction, the first mounting hole 313 is arranged at the intersection of the first wire groove 311 and the first wire hole 312, and the chrome-plated pin shaft 500 is mounted on the first pin 310 through the first mounting hole 313.

[0057] It can be understood that the design of the first mounting hole 313 allows the chrome-plated pin shaft 500 to be accurately installed to a predetermined position on the first pin 310, which is exactly the intersection of the first wire groove 311 and the first wire hole 312. This accurate positioning ensures that the chrome-plated pin shaft 500 can effectively reduce the friction of the wire rope 400 when sliding on the first pin 310, while maintaining the smooth passage of the wire rope 400. The position design of the first mounting hole 313 enables the chrome-plated pin shaft 500 to be accurately installed at the intersection of the first wire groove 311 and the first wire hole 312, ensuring that it can most effectively reduce friction and protect the first pin 310.

[0058] At the same time, the first mounting hole 313 provides a convenient installation entrance for the chrome-plated pin shaft 500. Through the first mounting hole 313, the chrome-plated pin shaft 500 can be easily installed or replaced, greatly simplifying the maintenance process.

[0059] Referring to Figure 5 and Figure 8 According to the folding screen door 10, the second pin 320 is provided with a second wire groove 321 on each of the two opposite sides perpendicular to the first direction, and the second wire hole 322 is arranged in the second pin 320, the second wire hole 322 is communicated with the two second wire grooves 321 respectively, and the chrome-plated pin shaft 500 is arranged at the end of the two second wire grooves 321 away from the second wire hole 322.

[0060] It can be understood that the second pin 320 is provided with a second wire groove 321 on each of the two opposite sides perpendicular to the first direction (i.e. the direction of the guide rail 120). It ensures that the wire rope 400 can pass smoothly through the two sides of the pin. Each second wire groove 321 provides a clear guide path for the wire rope 400, ensuring that the wire rope 400 can pass smoothly through the pin area, avoiding the wire rope 400 from deviating or winding during the pulling process.

[0061] The second wire hole 322 is arranged in the second pin 320, and the wire rope 400 passes from one side to the other side. It is communicated with the two second wire grooves 321, forming a channel through which the wire rope 400 can pass freely.

[0062] The chromium-plated pin shaft 500 is arranged at the two second wire passing grooves 321 away from the second wire passing hole 322. This is the contact point when the wire rope 400 passes through the pin, and it is also a part with severe friction. The application of the chromium-plated pin shaft 500 here converts the friction between the original pin and the wire rope 400 into the friction between the chromium-plated pin shaft 500 and the wire rope 400, which significantly reduces the friction between the wire rope 400 and the pin. This not only makes the pull rod operation smoother, but also reduces the wear of the wire rope 400 and the pin. Since the chromium-plated pin shaft 500 is located at the most severely frictional part, it effectively disperses the frictional force and prolongs the service life of the wire rope 400 and the pin.

[0063] With reference to Figure 5 and Figure 8 , according to the folding screen door 10 provided by the utility model, the folding screen door 10 further comprises a U-shaped stainless steel piece 600, which is arranged at the intersection of the second wire passing hole 322 and the two second wire passing grooves 321.

[0064] It can be understood that the U-shaped stainless steel piece 600 is a wear-resistant component added to the second pin 320, and its main function is to enhance the wear resistance of the contact area between the wire rope 400 and the pin, preventing wear caused by long-term use. The U-shaped design can provide uniform support and protection around the wire rope 400 and the branch, reducing direct contact between the wire rope 400 and the pin, thereby reducing wear.

[0065] With reference to Figure 5 and Figure 8 , according to the folding screen door 10 provided by the utility model, two second mounting holes 323 are arranged on the side of the second pin 320 facing the first pin 310, and the two second mounting holes 323 are respectively arranged at the ends of the two second wire passing grooves 321, and the chromium-plated pin shaft 500 is mounted on the second pin 320 through the second mounting hole 323.

[0066] It can be understood that the two second mounting holes 323 arranged on the second pin 320 are carefully designed to correspond to the ends of the second wire passing grooves 321. This design ensures that the chromium-plated pin shaft 500 can be accurately installed at the predetermined position, thereby achieving precise positioning of the structure of the folding screen door 10. At the same time, the second mounting hole 323 provides a convenient installation and replacement entrance for the chromium-plated pin shaft 500, simplifying the maintenance process and improving the maintainability of the equipment.

[0067] With reference to Figure 5 and Figure 8 , according to the folding screen door 10 provided by the utility model, the second pin 320 is provided with a mounting clamping groove 324 on the side away from the second wire passing groove 321 corresponding to the second wire passing hole 322, and the U-shaped stainless steel piece 600 is mounted on the second pin 320 through the mounting clamping groove 324.

[0068] It can be understood that the mounting groove 324 is a groove provided on the second pin 320 for fixing the U-shaped stainless steel piece 600. The mounting groove 324 provides a stable mounting position, so that the U-shaped stainless steel piece 600 can be firmly attached to the pin.

[0069] Referring to Figure 5 and Figure 7 According to the folding screen door 10 provided by the utility model, the part of the outer cylindrical surface of the chrome-plated pin shaft 500 protruding from the outer facade of the second pin 320 is arranged.

[0070] It can be understood that the part of the outer cylindrical surface of the chrome-plated pin shaft 500 protruding from the outer facade of the second pin 320, that is, the part of the chrome-plated pin shaft 500 protruding from the outer facade of the second pin 320, can better support the wire rope 400, so as to reduce the possibility of the wire rope 400 contacting the outer facade of the second pin 320, reduce the friction between the wire rope 400 and the pin when the screen door is opened and closed, and reduce the abrasion.

[0071] In an embodiment, the chrome-plated pin shaft 500 is rotatably mounted on the first pin 310 or the second pin 320.

[0072] It can be understood that by rotatably arranging the chrome-plated pin shaft 500 on the first pin 310 or the second pin 320, the original sliding friction is converted into rolling friction, and the rolling friction coefficient is generally smaller than the sliding friction coefficient, so that the resistance during the overall operation is reduced, and the pull rod is easier to pull.

[0073] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
