DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-4 The utility model provides a technical solution: a punch-free curtain, comprising a ceiling plate 1, a double-sided adhesive strip 2 is bonded to the top of the ceiling plate 1, a pleated curtain body 3 is fixed to the bottom of the ceiling plate 1, four positioning ropes 4 are fixed to the bottom of the ceiling plate 1 and are passed through the outside of the pleated curtain body 3, a retraction shell 500 is fixed to the bottom of the pleated curtain body 3, and a limiting component for unfolding and recovering is installed at the bottom of the retraction shell 500; through the cooperation between the double-sided adhesive strip 2 at the top of the ceiling plate 1 and the pleated curtain body 3, the positioning rope 4, the retraction shell 500, the limiting slider 600 and the button 700 at the bottom, the overall weight is light, and there is no need to punch holes for installation, and the opening and retraction effects can be achieved through simple structural cooperation, so that the curtain can be easily and conveniently installed next to the window without punching holes to play a role of shading and filtering. At the same time, since the overall structure used is very simple, the required cost is greatly reduced, the cost is effectively controlled, and the practical performance of the pleated curtain is effectively improved.

[0025] In this embodiment, the limiting assembly is a structure used to adjust and limit the pleated curtain body 3.

[0026] like Figure 1 and Figure 2As shown, the limiting assembly includes a limiting slider 600 slidably connected to the bottom of the retracting shell 500 for concentrating the positioning rope 4 and a button 700 inserted into the front of the limiting slider 600 for limiting the positioning rope 4.

[0027] It should be noted that the ceiling plate 1, the retractable shell 500, the limit slider 600 and the button 700 are all made of plastic, which are light in texture, making the overall structure light in weight and easy to install. The pleated curtain body 3 is made of curtain fabric that is repeatedly folded in a wavy shape.

[0028] In this embodiment, the limiting slider 600 is a structure used to centralize the positioning rope 4 so as to facilitate limiting the positioning.

[0029] like Figure 1 and Figure 3 As shown, the limiting slider 600 includes a slider base 601 that slides in close contact with the bottom of the retracting shell 500, a slide groove 602 opened on the slider base 601 on one side close to the retracting shell 500, an inserting tube 603 fixed on the other side of the slider base 601, and a first rope threading hole 604 opened between the bottom of the inserting tube 603 and the top of the slider base 601.

[0030] It should be noted that the left and right sides and the top of the retracting shell 500 are open, and a rectangular protrusion is fixed to the bottom of the retracting shell 500. The inner side of the slide groove 602 is slidably connected to the outer side of the rectangular protrusion. The left and right sides of the slide groove 602 are open, so that the slider base 601 can be placed in the bottom of the retracting shell 500 through the sliding connection between the slide groove 602 and the rectangular protrusion.

[0031] In this embodiment, the button 700 is a structure for elastically positioning the positioning rope 4.

[0032] like Figure 1 and Figure 4 As shown, the button 700 includes a plug-in rod 701 inserted into the inner side of the plug-in tube 603, a push head 702 fixed to the end of the plug-in rod 701, a positioning column 703 fixed to the other end of the plug-in rod 701, and a second rope threading hole 704 opened on the outer side of the plug-in rod 701 and connected to the inner side of the first rope threading hole 604.

[0033] It should be noted that the left and right inner sides of the plug-in cylinder 603 are both planes, and the inner top wall and the inner bottom wall of the plug-in cylinder 603 are both curved surfaces. The front side of the plug-in cylinder 603 is open, and the outer side of the plug-in rod 701 is slidably connected to the inner side of the plug-in cylinder 603, so that the plug-in rod 701 can be plugged into the inner side of the plug-in cylinder 603 through the front side, so that the planes on both sides can limit the position of the plug-in rod 701 to prevent the plug-in rod 701 from rotating after being plugged into the inside of the plug-in cylinder 603. The diameter of the push head 702 is larger than the inner diameter of the plug-in cylinder 603, so that the push head 702 can be operated on the outside of the plug-in cylinder 603 for the convenience of the operator.

[0034] In addition, the end of the plug-in rod 701 is fixedly connected to an elastic member located on the outside of the positioning column 703, and the other side of the elastic member is fixedly connected to the inner side of the plug-in tube 603. The elastic member can be a spring, and the fixed connection method can be bonding. The tail end of the positioning rope 4 can pass through the left and right sides of the slide groove 602 to the inside of the first rope threading hole 604 and the second rope threading hole 704. When the elastic member is in a natural state, the inside of the first rope threading hole 604 is not connected to the inside of the second rope threading hole 704, and at this time, the end of the plug-in rod 701 is located on the inner side of the plug-in tube 603. When the pressing head 702 is in contact with the plug-in tube, the end of the plug-in rod 701 is located on the inner side of the plug-in tube 603. When the outer sides of the tube 603 are abutted, the interiors of the first rope threading hole 604 and the second rope threading hole 704 are connected, and four positioning ropes 4 can be moved, so that by utilizing the elastic restoring effect of the elastic member, the connecting area of ​​the first rope threading hole 604 and the second rope threading hole 704 can be controlled by the button 702 and the connecting rod 701. When they are not connected, the positioning rope 4 can be positioned by the extrusion limit between the inner walls of the first rope threading hole 604 and the second rope threading hole 704. When they are connected, the pleated curtain body 3 can be adjusted by moving the retracting shell 500 upward or downward.

[0035] The working principle of the above embodiment is:

[0036] When installing the curtain, the double-sided adhesive strip 2 is pasted on the top of the ceiling plate 1, and the other side is pasted on the top of the window. The positioning rope 4 is passed through the first rope threading hole 604 and the second rope threading hole 704 from any direction, and the button 702 is pressed to increase the communication area between the first rope threading hole 604 and the second rope threading hole 704, thereby reducing the friction between the positioning rope 4 and the inner walls of the first rope threading hole 604 and the second rope threading hole 704. The slider base 601 can be moved to the bottom of the retracting shell 500, and the button 702 is released, so that the positioning rope 4 is connected between the first rope threading hole 604 and the second rope threading hole 704. The second rope threading hole 704 is positioned under the action of the squeezing friction between the inner walls, so that the unfolded state of the pleated curtain body 3 can be limited. When it is necessary to unfold or retract, according to the above principle, the button 702 is pressed to increase the internal connection area of ​​the first rope threading hole 604 and the second rope threading hole 704, so that the positioning rope 4 loses the squeezing limit, and the tail end of the positioning rope 4 can be pulled. The retraction shell 500 is moved upward to recycle the pleated curtain body 3, and moved downward to unfold the pleated curtain body 3, realizing the functions of unfolding and retracting through a simple structure.

[0037] Compared with the prior art, the punch-free curtain, through the coordinated use of the double-sided adhesive strip 2 on the top of the ceiling plate 1 and the pleated curtain body 3, the positioning rope 4, the retraction shell 500, the limit slider 600 and the button 700 at the bottom, has an overall light weight, does not require punching for installation, and can achieve the opening and retraction effects through simple structural coordination, so that the curtain can be easily and conveniently installed next to the window without punching to play a role in shading and filtering. At the same time, since the overall structure used is very simple, the required cost is greatly reduced, the cost is effectively controlled, and the practical performance of the pleated curtain is effectively improved, which solves the problem that most existing pleated curtains need to be installed by screws and holes, and the number of structures is large.
