Description

Curtain

Technical Field

The invention relates to the field of curtains, in particular to a curtain.

Background

The curtain is made of cloth, hemp, yarn, aluminum sheet, wood chip, metal material and the like, has the functions of shading, insulating heat and adjusting indoor light, is divided into cotton gauze, polyester fabric, polyester-cotton blended fabric, cotton-hemp blended fabric, non-woven fabric and the like according to the material, and is formed into different styles of curtains by combining different materials, textures, colors, patterns and the like, and is matched with different styles of indoor design curtains.

In the process of implementing the invention, the inventor finds that at least the following problems in the prior art are not solved: 1. at present, most of curtains used in family rooms are provided with a plurality of hanging rings to hang curtain cloth in front of the window, the curtain cloth needs to be pulled manually to control the indoor light intensity, the curtain cloth is pulled very hard due to the fact that friction force is generated between the hanging rings and hanging rods when the curtain cloth is pulled, and the curtain cloth is easy to damage due to long-term pulling force, so that the using cost of the curtain is increased;

2. because modern curtain cloth is mostly made of materials such as cloth, hemp, yarn and the like, and the curtain cloth has a large surface area and is easy to adsorb dust and other stains, the curtain cloth needs to be cleaned frequently in order to ensure the cleanness of the home environment, but the existing curtain is not convenient to detach and install the curtain cloth, thereby bringing inconvenience to users.

Therefore, a curtain is provided.

Disclosure of Invention

The invention aims to provide a curtain, which is provided with a sliding mechanism, a user can drive a sliding block to move by controlling the operation of the sliding mechanism, the sliding block is connected with a hanging rod through a roller in a rolling way, so that the friction force between the sliding block and the hanging rod when the sliding block moves is reduced, the opening and closing of curtain cloth are controlled by controlling the sliding mechanism, and the problem that the curtain cloth is pulled by manpower in the traditional curtain, the curtain cloth is prevented from being damaged easily due to long-term tension, and the use cost of the curtain is increased is solved.

In order to achieve the purpose, the invention provides the following technical scheme: including the peg, the rear of peg is provided with the wall body, the spout has been seted up to the annular surface of peg near the position at edge, the inside roll connection of spout has the gyro wheel, one side fixedly connected with slider of spout is kept away from to the gyro wheel, the quantity of slider is a plurality of, and wherein the upper end position fixedly connected with slide mechanism of slider, slide mechanism and wall body fixed connection, the annular surface of slider is close to the position fixedly connected with connecting block of lower extreme, the lower extreme fixedly connected with fixed block of connecting block, the inside through connection of fixed block has the link, the position that the inside of link is close to the lower extreme has cup jointed solid fixed ring, the below of slider is provided with the curtain cloth, gu fixed ring's inside and curtain cloth fixed connection.

Through setting up slide mechanism, user's accessible control slide mechanism's operation drives the slider and removes, because the slider passes through roll connection between gyro wheel and the peg, frictional force between slider and the peg when having reduced the slider and removing, through controlling opening and closing of slide mechanism come control curtain cloth, replace traditional (window) curtain and need come the pulling curtain cloth through the manpower, avoid the curtain cloth to receive the pulling force for a long time and take place to damage easily to the condition that has increased (window) curtain use cost takes place.

Preferably, the connecting groove has been seted up to the lower extreme surface of connecting block, two draw-in grooves have been seted up to the annular internal surface bilateral symmetry of connecting groove, the inside fixedly connected with fixed block of connecting groove, the inside symmetry swing joint of fixed block has two L shaped plates, L shaped plate and draw-in groove block each other, the outer fixed surface of one side that the draw-in groove was kept away from to the L shaped plate is connected with the spring, one side and the fixed block fixed connection that the L shaped plate was kept away from to the spring, the shifting chute has been seted up to the lower extreme surface of fixed block, the inside sliding connection of shifting chute has the movable block, the diameter of movable block is the same with the internal diameter of shifting chute, the outer fixed surface of upper end of movable block is connected with the L shaped plate, the outer fixed surface of lower extreme of movable block is connected with and draws the piece.
