Technical Field

The utility model relates to the field of articles for daily use, concretely relates to wireless (window) curtain.

Background

The existing up-and-down telescopic curtain used by people adopts a rope pulling method to solve the problem of up-and-down telescopic motion of the curtain, and the existing mechanism has defects, so that the curtain can be clamped in the up-and-down telescopic process, and meanwhile, the time consumption is too long when people pull the rope, and the curtain is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cordless curtain in order to solve above-mentioned problem to adopt the stay cord to drive the up-and-down concertina movement of curtain among the solution prior art and waste time and energy, operate inconveniently, the stay cord twines the card scheduling problem of dying easily moreover. The utility model provides an among a great deal of technical scheme preferred technical scheme can realize putting down and rising the in-process at needs (window) curtain and need not the stay cord, adopts the hand push to draw (window) curtain concertina movement about accomplishing, realizes the high free location of (window) curtain, owing to do not have complicated stay cord mechanism, can not have blocking phenomenon and can fix a position fast at the flexible in-process about the (window) curtain, makes things convenient for technical effect such as people use, sees the explanation below in detail.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a pair of wireless (window) curtain, including receiving the spool, it has the casement to wind on the spool to receive the line, keep away from the one end of receiving the spool on the casement and install the (window) curtain lower pull rod, it has the mounting box to receive the epaxial roller sleeve of line, mounting box fixed mounting is on the wall, fixed mounting has the variable force spring in the mounting box, the variable force spring convolute on receiving the spool and with receive spool fixed connection, when pulling (window) curtain lower pull rod downwardly movement expansion casement, the variable force spring begins the energy storage, when upwards promoting (window) curtain lower pull rod, the variable force spring begins to drive and receives the spool rotation and roll up the casement.

Preferably, the variable force springs are multiple in number and are uniformly distributed on the take-up shaft.

Preferably, the sum of the rotating torque force of all the variable force springs on the take-up shaft is equal to the gravity of the unfolded curtain cloth and the curtain lower pull rod.

Has the advantages that: a cordless (window) curtain can realize putting down and rising in-process at needs (window) curtain and need not the stay cord, adopt the hand push to draw (window) curtain concertina movement about accomplishing, realize the high free location of (window) curtain, owing to do not have complicated stay cord mechanism, flexible in-process can not have the blocking phenomenon and can fix a position fast about the (window) curtain, make things convenient for people to use.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is an internal structure view of the mounting box of the present invention.

The reference numerals are explained below:

1. taking up a spool; 2. curtain cloth; 3. a curtain lower pull rod; 4. mounting a box; 5. a variable force spring.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the utility model provides a pair of wireless (window) curtain, including receiving wire shaft 1, it has casement 2 to wind on the receiving wire shaft 1, casement 2 is last to keep away from the one end of receiving wire shaft 1 and installs (window) curtain lower tie 3, curtain lower tie 3 is used for guaranteeing that the casement 2 surface that expandes is level and smooth, the roller shell has mounting box 4 on the receiving wire shaft 1, mounting box 4 fixed mounting is on the wall, fixed mounting has variable force spring 5 in the mounting box 4, variable force spring 5 is used for driving receiving wire shaft 1 rotation and packs up casement 2, variable force spring 5 winds on receiving wire shaft 1 and with receiving wire shaft 1 fixed connection, when pulling curtain lower tie 3 and removing expansion casement 2 downwards, variable force spring 5 begins the energy storage, when upwards promoting curtain lower tie 3, variable force spring 5 begins to drive receiving wire shaft 1 rotation and rolls up casement 2.

As optional embodiment, variable force spring 5 quantity has a plurality ofly, and evenly distributed is on receiving spool 1, and a plurality of variable force springs 5 make things convenient for receiving spool 1's installation, promptly as long as will set up on the installation box 4 fixed mounting wall at receiving spool 1 both ends can, need not additionally to install fixedly receiving spool 1.

The sum of the rotating torque force of all the variable force springs 5 on the take-up shaft 1 is equal to the gravity of the unfolded curtain cloth 2 and the curtain lower pull rod 3, and therefore the curtain cloth 2 cannot be rolled up by the take-up shaft 1 when the curtain lower pull rod 3 is loosened by hands.

When the cordless curtain is used, when the curtain needs to be unfolded downwards, the curtain lower pull rod 3 can be pulled by hand to move downwards, the curtain cloth 2 is unfolded and drives the wire take-up shaft 1 to rotate, the wire take-up shaft 1 rotates to enable the variable force spring 5 to start energy storage, when the curtain lower pull rod 3 descends to a preset position, the hand can be released, the rotating torque of the variable force spring 5 to the wire take-up shaft 1 is equal to the sum of the weights of the unfolded curtain cloth 2 and the curtain lower pull rod 3, therefore, the curtain lower pull rod 3 cannot rise automatically after the hand is released, namely, the wire take-up shaft 1 is in a stress balance state (commonly called a hovering state), the curtain can be instantly hovered at any position in an effective stroke, the cordless curtain is very convenient, when the curtain needs to be folded, the curtain lower pull rod 3 is pushed to rise, at the moment, the stress balance of the wire take-up shaft 1 is broken due to the upward pushing force of the curtain lower pull rod 3 by hand, namely, the torque of the variable force spring 5 to The lower pulling force, therefore, the take-up shaft 1 rotates to wind up the curtain cloth 2 under the action of the variable force spring 5, and simultaneously drives the curtain lower pull rod 3 to rise.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
