Description

Curtain cord fixing device

Technical Field

The utility model relates to an invisible curtain accessory field especially relates to a curtain cotton rope fixing device.

Background

Common passenger car (bus) curtain all is the curtain of the cloth curtain or the nylon material of violently pulling about, mostly is the top slide rail, hangs cloth curtain or nylon curtain below, still can rock during the driving process, also hardly reaches the effect of adjusting at will. Patent publication No. CN201820045852.6 proposes a curtain rod assembly for a caravan, the curtain rod assembly for the caravan of the utility model adopts a magnetic stripe to realize the tight closing of an upper curtain and a lower curtain, and simultaneously pulls a handle upwards or downwards, thus realizing the use of curtains with different functions; and set up the recess on the pull rod and regard as the handle, need not extra external bulge, operating force is less, can not injure passenger, simple structure, simple to operate saves the interior space of car.

However, the cord for positioning and guiding the folding curtain is arranged in the folding curtain, the resistance in the curtain pulling process is adjusted by adjusting the tightness of the cord, and the using hand feeling is adjusted, so that the cord resistance is large, and the using hand feeling is not smooth. The elastic force of the thread rope needs to be adjusted repeatedly in the production process and then the thread rope is fixed, the thread rope is easy to break in the adjustment process, the position of the thread rope needs to be adjusted repeatedly in the production process, and the efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a (window) curtain cotton rope fixing device solves the cotton rope and adjusts inefficiency, the great problem of resistance during the use.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model relates to a (window) curtain cotton rope fixing device, including nut locking piece, screw and spring, the spout has been seted up on the window frame, the one end of spring is passed through the fix with screw on the nut locking piece, the nut locking piece set up in the spout, the other end and the cotton rope of spring are connected, the spring passes through after tensile to predetermined length the screw will the nut locking piece is fixed on the spout.

Furthermore, one side end of the spring is designed into a hook shape to facilitate hanging of the screw, and the other side end of the spring is designed into a circular ring shape and used for hanging of a thread rope.

Furthermore, a threaded through hole matched with the screw is formed in the middle of the nut locking block.

Furthermore, the size of the nut locking block is matched with the sliding groove.

Further, the width of the upper opening of the sliding groove is smaller than the outer diameter of the screw.

Still further, a rubber layer is arranged in the sliding groove.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses the spring increases taut spring between cotton rope and fixed point, and spring one end is connected with the cotton rope, and the other end is fixed in the spout. The elasticity of spring provides tension for the cotton rope to reach suitable elasticity degree, simultaneously at handle pulling in-process, cotton rope tension has slight change, and corresponding change can also be made to spring extension length and compensate the tensile slight change of cotton rope, thereby stabilizes the tensile undulant of cotton rope, makes the pulling feel more steady light, lets the slip process light smoothly more.

Just the utility model discloses can reflect the cotton rope elasticity degree directly perceived in the use, avoid the waste of readjusting the cotton rope position repeatedly.

In a word, the utility model discloses easily installation stimulates steadily easily, promotes user experience and feels, effectively increases the life of cotton rope, improves debugging efficiency.

Drawings

The present invention will be further explained with reference to the following description of the drawings.

Fig. 1 is a schematic structural view of the curtain cord fixing device of the present invention;

fig. 2 is an installation schematic view of the curtain cord fixing device of the present invention;

FIG. 3 is a schematic view of the connection of the curtain cord fixing device of the present invention

Description of reference numerals: 1. a nut locking block; 2. a screw; 3. a spring; 4. a chute; 5. curtain frame.

Detailed Description

As shown in fig. 1, a curtain cord fixing device comprises a nut locking block 1, a screw 2 and a spring 3, wherein a sliding groove 4 is formed in a window frame 5, one end of the spring 3 is fixed on the nut locking block 1 through the screw 2, the nut locking block 1 is arranged in the sliding groove 4, the other end of the spring 3 is connected with a cord, and the nut locking block 1 is fixed on the sliding groove 4 through the screw 2 after the spring 3 is stretched to a preset length.

Specifically, one side end of the spring 3 is designed into a hook shape to facilitate hanging the screw 2, and the other side end of the spring 3 is designed into a circular ring shape and used for hanging the thread rope. The middle position of the nut locking block 1 is provided with a thread through hole matched with the screw 2.

More specifically, the size of the nut locking block 1 is matched with the sliding groove 4, so that debugging before installation is facilitated. The width of the upper opening of the sliding groove 4 is smaller than the outer diameter of the screw 2, so that the screw is prevented from falling off after installation. A rubber layer is arranged in the sliding groove 4, so that the screw 2 can be fixed conveniently.

The utility model discloses a use as follows:

firstly, referring to fig. 1-3, window frames 5 are installed on two sides of a window, a groove is formed on the window frame 5 and connected with a sliding mechanism for pulling a folding curtain, and a sliding groove 4 is formed at the bottom of the groove.

One end of a spring 3 is fixed on a nut locking block 1 through a screw 2, the nut locking block 1 is arranged in a sliding groove 4, the other end of the spring 3 is connected with one end of a cord, the other end of the cord penetrates through the curtain cloth to guide the curtain cloth, and the spring 3 is fixed on the sliding groove 4 through the screw 2 after being stretched to a preset length.

The waste of adjusting the cotton rope position repeatedly among the dark commentaries on classics process of production has been solved to this embodiment, and the spring is tensile to predetermined length can provide required pulling force, is cotton rope tension visualizes, can directly perceived reflection cotton rope elasticity degree. In the pulling process of the handle, the tension of the cotton rope can be slightly changed, and the stretching length of the spring can also be correspondingly changed, so that the fluctuation of the tension of the cotton rope is stabilized, and the pulling hand feeling is more stable and easier.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
