DETAILED DESCRIPTION

[0020] 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 in 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.

[0021] As attached Figure 1-6 The anti-ultraviolet flame-retardant curtain shown comprises a crossbar 1 and a curtain body 2 mounted on the crossbar 1. A plurality of embedding holes are provided on the surface of the curtain body 2, and mounting rings 3 are installed inside the plurality of embedding holes.

[0022] Specifically, in this structure, the crossbar 1 can be installed at the top of the window, and the curtain body 2 can slide outside the crossbar 1 through the mounting ring 3, so that the curtain body 2 can be opened and closed.

[0023] In a specific embodiment, as shown in the attached Figure 2 , 3 As shown in Figures 4 and 5, a detachable ball structure is arranged inside the mounting ring 3. The detachable ball structure includes two arc plates 4. The two arc plates 4 are symmetrically mounted inside the mounting ring 3. The inner walls of the two arc plates 4 are provided with a plurality of mounting grooves 5. A mounting seat 6 is arranged inside the mounting groove 5. A circular groove 7 is arranged on the surface of the mounting seat 6. A ball 8 is rollingly mounted inside the circular groove 7. A reset spring 9 is arranged on one side of the mounting seat 6 inside the mounting groove 5. A card slot 10 is arranged on the inner wall of the mounting ring 3. The outer wall of the arc plate 4 is provided with a mounting groove 10. There is a clamping block 11, and the clamping block 11 on the outer wall of the arc plate 4 is adapted to the clamping groove 10 structure on the inner wall of the mounting ring 3. Connecting plates 12 are provided at the upper and lower ends of the two arc plates 4. The surfaces of the two connecting plates 12 are provided with mounting holes. The internal threads of the mounting holes are installed with fastening bolts 13. A circular structure is formed between the two arc plates 4. The cross bar 1 is installed inside the circular structure formed by the two arc plates 4. The mounting seat 6 is slidably connected inside the mounting groove 5. The two ends of the reset spring 9 are respectively connected to the mounting seat 6 and the inner wall of the mounting groove 5.

[0024] Specifically, in this structure, during the process of opening and closing the curtain body 2, the multiple balls 8 at the arc plate 4 can rotate inside the corresponding circular groove 7 and slide on the outer surface of the cross bar 1, thereby reducing the wear of the mounting ring 3 and the cross bar 1 and increasing the service life of the mounting ring 3. In addition, during the process of the balls 8 rolling on the outer surface of the cross bar 1, the reset spring 9 is squeezed and reset, thereby ensuring that the mounting seat 6 drives the balls 8 to always fit on the outer surface of the cross bar 1, thereby improving the smoothness of opening and closing of the curtain body 2 and reducing the noise during friction and sliding.

[0025] When it is necessary to maintain the ball 8, such as adding lubricating oil, the fastening bolts 13 on the two connecting plates 12 at the arc plate 4 are released. At this time, the connection between the two arc plates 4 is lost, and the arc plate 4 is slid from the outside of the mounting ring 3, so that the block 11 is disengaged from the inside of the slot 10, and the arc plate 4 can be pulled out from the inside of the mounting ring 3, and then the ball 8 inside the arc plate 4 can be maintained.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 6As shown, the curtain body 2 includes a base layer 20, a flame retardant layer 21 is provided at the top and bottom of the base layer 20, an anti-ultraviolet layer 22 is provided at the top and bottom of the flame retardant layer 21, an anti-static layer 23 is provided at the top and bottom of the anti-ultraviolet layer 22, the flame retardant layer 21 is a polyester flame retardant cloth, the anti-ultraviolet layer 22 is woven from polyester fibers, and the anti-static layer 23 is woven from polyvinyl chloride fibers.

[0027] Specifically, in this structure, the flame retardant layer 21 composed of polyester flame retardant cloth can improve the flame retardant effect of the curtain body 2, and the anti-ultraviolet layer 22 woven from polyester fibers can improve the anti-ultraviolet effect of the curtain body 2. At the same time, the anti-static layer 23 woven from polyvinyl chloride fibers can improve the anti-static effect of the curtain body 2, thereby avoiding dust adhering to the surface of the curtain body 2 due to static electricity and causing pollution, thereby affecting the aesthetics of the curtain body 2.

[0028] Working principle of this utility model:

[0029] When the above structure is used, the curtain body 2 is composed of a base layer 20, a flame retardant layer 21, an anti-ultraviolet layer 22 and an anti-static layer 23, so that the curtain body 2 has good flame retardancy, anti-static and anti-ultraviolet effects;

[0030] When the curtain body 2 is opened and closed, the multiple balls 8 on the arc plate 4 can rotate inside the corresponding circular grooves 7 and slide on the outer surface of the cross bar 1, thereby reducing the wear of the mounting ring 3 and the cross bar 1 and increasing the service life of the mounting ring 3. In addition, during the rolling process of the balls 8 on the outer surface of the cross bar 1, the reset spring 9 is squeezed and reset, thereby ensuring that the mounting seat 6 drives the balls 8 to always fit on the outer surface of the cross bar 1, thereby improving the smoothness of opening and closing of the curtain body 2 and reducing the noise during friction and sliding.

[0031] When the ball 8 needs to be maintained, the fastening bolts 13 on the two connecting plates 12 at the arc plate 4 are released. At this time, the connection between the two arc plates 4 is lost, and the arc plate 4 is slid from the outside of the mounting ring 3, so that the block 11 is disengaged from the inside of the slot 10, and the arc plate 4 can be pulled out from the inside of the mounting ring 3, and then the ball 8 inside the arc plate 4 can be maintained.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
