Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a winding curtain. Background Art

[0002] The main function of curtains is to isolate from the outside world and maintain the privacy of the living room. At the same time, it is an indispensable decoration for home improvement. In winter, the curtain divides the indoor and outdoor into two worlds, adding a warm atmosphere to the room. Modern curtains can not only reduce or block light to meet people's different light intensity requirements, but also prevent fire, wind, dust, keep warm, reduce noise, insulate heat, prevent radiation, prevent ultraviolet rays, etc., improving the indoor climate and environment. Therefore, the ingenious combination of decoration and practicality is the biggest feature of modern curtains.

[0003] A ventilation and windproof curtain with the application (patent) number of CN201020285323.7 includes a curtain body. There are suckers at the bottom end of the curtain body, and multiple through holes are arranged on the surface of the curtain body. When in use, the suckers at the bottom end of the curtain body can adsorb on the bottom edge of the window frame to play a role in wind prevention. The multiple through holes on the surface of the curtain body facilitate the gentle breeze outside to blow into the room. Although the through holes can provide ventilation, they can also transmit light. In this way, the outdoor sunlight passes through the through holes and shines into the room, forming light rays, which affects the light-shielding effect. Summary of the Invention

[0005] To achieve the above purpose, the utility model proposes a winding curtain, including a curtain body. There are several openings on the curtain body, and ventilation mechanisms are arranged on the openings. The ventilation mechanism includes a hollow bag body. There are several elastic support bodies arranged at intervals in the hollow bag body. Ventilation areas I and II are respectively arranged on the front and rear side walls of the hollow bag body, and the ventilation area I and the ventilation area II are arranged alternately.

[0006] Preferably, both the ventilation area I and the ventilation area II are of mesh structure.

[0007] Preferably, a counterweight rod is arranged at the lower end of the curtain body. Hooks are arranged at both ends of the counterweight rod, and hanging seats that are matched with the hooks and fixed on the window frame are hung on the hooks.

[0008] Preferably, it further includes a winding mechanism for winding the curtain body. The winding mechanism includes a housing I, a rolling curtain shaft, and a winding driving mechanism. There is a curtain body through hole for the curtain body to pass through at the lower end of the housing I. A rolling curtain shaft is arranged in the housing I, and a winding driving mechanism for driving the rolling curtain shaft is arranged at the rear end of the housing I.

[0009] Preferably, the winding drive mechanism includes a housing II, a worm gear, a worm, a bead chain and a bead sprocket. The worm is provided on the housing II. One end of the worm is provided with a bead sprocket. The bead chain is provided on the bead sprocket. The worm is meshed and connected with the worm gear provided on the rolling curtain shaft.

[0010] Advantages of the present utility model: By providing a plurality of openings on the curtain body, and ventilation mechanisms are provided on each opening. The ventilation mechanism includes a hollow bag body. A plurality of elastic support bodies are provided at intervals in the hollow bag body. Ventilation areas I and II are respectively provided on the front and rear side walls of the hollow bag body. The ventilation area I and the ventilation area II are arranged in an alternating manner. While ensuring the ventilation effect, sunlight is prevented from irradiating into the room through the ventilation mechanism. Compared with the prior art, it has good ventilation and light-shielding effects and can better meet the working environment of people.

[0011] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings. Description of the Drawings

Detailed Embodiments

[0015] Referring to Figure 1 、 2 , a winding type curtain of the present utility model includes a curtain body 1. A plurality of openings 2 are provided on the curtain body 1. Ventilation mechanisms 3 are provided on each of the openings 2. The ventilation mechanism 3 includes a hollow bag body 31. A plurality of elastic support bodies 32 are provided at intervals in the hollow bag body 31. Ventilation areas I 33 and ventilation areas II 34 are respectively provided on the front and rear side walls of the hollow bag body 31. The ventilation areas I 33 and the ventilation areas II 34 are arranged in an alternating manner.

[0016] Both the ventilation area I 33 and the ventilation area II 34 are of a mesh structure.

[0017] A counterweight rod 4 is provided at the lower end of the curtain body 1. Hooks 5 are provided at both ends of the counterweight rod 4, and hanging seats 6 that are matched with and fixed on the window frame are hung on the hooks 5.

[0018] It further includes a winding mechanism 7 for winding the curtain body 1. The winding mechanism 7 includes a housing I 71, a rolling curtain shaft 72, and a winding driving mechanism 73. A curtain body through-hole through which the curtain body 1 can pass is provided at the lower end of the housing I 71. A rolling curtain shaft 72 is provided inside the housing I 71, and a winding driving mechanism 73 for driving the rolling curtain shaft 72 is provided at the rear end of the housing I 71.

[0019] The winding driving mechanism 73 includes a housing II 731, a worm gear 732, a worm 733, a bead chain 734, and a bead sprocket 735. A worm 733 is provided on the housing II 731. A bead sprocket 735 is provided at one end of the worm 733. A bead chain 734 is provided on the bead sprocket 735. The worm 733 is meshed and connected with a worm gear 732 provided on the rolling curtain shaft 72.

[0020] The elastic support 32 is made of sponge.

[0021] The working process of the present utility model:

[0022] During the working process of a rolling curtain of the present utility model, by pulling the bead chain 734, the bead sprocket 735 is driven to rotate clockwise or counterclockwise. The bead sprocket 735 drives the rolling curtain shaft 72 to wind or unwind the curtain body 1.

[0023] External air enters the hollow bag body 31 from the air permeable area on one side, and then enters the room through the air permeable area on the other side. Since the air permeable areas on both sides are arranged staggeredly and have a large area, the wind can blow through the air permeable area, reducing the resistance of the curtain to the wind and achieving a certain windproof effect, thereby ensuring both a good ventilation effect and a sunshade effect.

[0024] The fixing of the counterweight rod 4 is realized through the cooperation of the hook 5 and the hanging seat 6, preventing the curtain body 1 from swinging when the external wind is strong and further improving the windproof effect.

[0025] The above embodiments are illustrative of the present utility model, not restrictive of the present utility model. Any solution obtained by simply transforming the present utility model belongs to the protection scope of the present utility model.
