Description

Technical Field

[0001] The utility model relates to the technical field of screen window screens, in particular to a C-shaped screen strip structure. Background Art

[0002] Invisible screens are popular among consumers due to their aesthetics and the convenience of opening and closing. They have been widely used in major construction companies and families. Invisible screens are screens with automatically retracted screens. They are mainly used for ventilation and mosquito prevention. Their frames are tightly attached to the window frames. When they are needed, the screens are pulled down. When they are not needed, the screens will automatically retract into the screen box. The screens can effectively block foreign mosquitoes and debris when the windows are open, and can be rolled up when the windows are closed to prevent dust and damage. They can also ensure the transparency of the windows. At the same time, they do not take up space and have strong sealing properties, which is coordinated with high-end home decoration.

[0003] At present, the common invisible screens mostly adopt the tie beam connection method of sewing ordinary plastic sheets. The screen is directly sewn to the plastic sheet and then installed in the tie beam profile. This method is relatively simple and direct, but the plastic sheet sewing connection method is often disposable and cannot be reused, causing waste when replaced; the sewing connection method often requires a sewing machine and professional workers to operate, and the production method is relatively cumbersome, thus causing cost increase; in addition, ordinary screen plates or plastic sheets are often simple in structure, and are easily deformed and damaged after long-term use, and then fall out of the tie beam profile, causing damage to the screen. In order to solve the above problems, a C-type screen strip structure is proposed. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a C-type yarn clamping strip structure, which is characterized by comprising an O-type pressure strip, a gauze net, a C-type yarn clamping strip, and a profile, wherein a gauze net is arranged outside the O-type pressure strip, a C-type yarn clamping strip is arranged outside the gauze net, and a profile is arranged outside the C-type yarn clamping strip;

[0005] Furthermore, the cross section of the O-shaped strip is gear-shaped, with a plurality of convex teeth on the surface, the mesh is located between the O-shaped strip and the C-shaped strip, the diameter of the O-shaped strip is larger than the opening size of the C-shaped strip, and the C-shaped strip fits the profile;

[0006] Furthermore, the C-shaped yarn clamping strip is composed of an upper protrusion, a first limiting portion, a second limiting portion, a third limiting portion, and a lower protrusion. The upper protrusion is located above the O-shaped pressure strip, the first limiting portion is located on the outside of the upper protrusion, and is connected to the upper protrusion as a whole, the first limiting portion is in contact with the profile, a second limiting portion is arranged below the first limiting portion, the second limiting portion is connected to the first limiting portion as a whole, the second limiting portion is in contact with the profile, a third limiting portion is arranged outside the second limiting portion, the third limiting portion is connected to the second limiting portion as a whole, the third limiting portion is in contact with the profile, a lower protrusion is arranged outside the third limiting portion, and the lower protrusion is connected to the third limiting portion as a whole.

[0007] Beneficial effects of the utility model:

[0008] 1. Convenient gauze pressing: The C-type gauze clamp adopts an integrated structure. The gauze net and O-type pressure strip are directly pressed into the C-type gauze clamp with a roller to complete the gauze installation. No sewing, nailing, screwing and other processes and equipment are required. At the same time, since no sewing and nailing are required, it is easier to replace the gauze net. You only need to take out the C-type gauze clamp, gauze net and O-type pressure strip directly from the side of the tension beam notch, and then take out the O-type pressure strip from the side of the C-type gauze clamp to complete the disassembly. No tools or machinery are required in the whole process.

[0009] 2. Good yarn pressing and positioning effect: The C-type yarn clamping strip adopts a unique C-type structure. During the use of the screen window, due to the pull-down and rewinding of the yarn net, the C-type yarn clamping strip, the yarn net and the O-type pressure strip will be displaced in the tension beam. The C-type structure can well fix the position of the yarn clamping strip, that is, through the three-point fixing method, the combined structure of the C-type yarn clamping strip, the yarn net and the O-type pressure strip will not rotate or fall in the notch of the tension beam, and will be well stuck in the notch of the tension beam to prevent the yarn clamping strip and the yarn net from escaping from the tension beam;

[0010] 3. Repeated use without damaging the O-shaped strip: Since the C-shaped yarn clamping strip is pressed directly by rollers, there is no need to fix it by nailing or sewing. During repeated use and replacement of the yarn, the O-shaped strip is minimally damaged. The O-shaped strip can be used multiple times without affecting the yarn pressing and clamping effects. This can greatly save the cost of replacing the yarn and is easy to maintain and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 2

[0023] When in use, wrap one end of the gauze 2 around the O-shaped pressure strip 1, and install the gauze 2 and the O-shaped pressure strip 1 into the C-shaped clamping strip 3 through rollers. At this time, the upper protrusion 31 and the lower protrusion 35 of the C-shaped clamping strip 3 fit the gauze 2 with the convex teeth on the surface of the O-shaped pressure strip 1, and contact and bear force with the O-shaped pressure strip 1.
