Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of windproof sunshade products, and particularly relates to a windproof curtain edge rail system. BACKGROUND

[0002] The windproof roller blind can provide windproof, sunshade, heat insulation and other functions for a building, and is mainly used in a roller blind system of an outdoor facade or an inclined surface. The main technology of the windproof roller blind is to prevent the cloth curtain from derailing under strong wind. The edge rails are arranged on the left and right sides of the cloth curtain, and the cloth curtain moves along the edge rails under the traction of the winding shaft to realize winding or unfolding. The structural design of the edge rails provides necessary conditions for the windproof function of the roller blind, directly affects the windproof effect and service life of the cloth curtain, and can perfectly hide the left and right edges of the cloth curtain in the edge rails to realize the edge light-tight and wind-tight functions.

[0003] The existing windproof roller blind edge rail system mainly uses elastic members to improve the movement flexibility of the cloth curtain from left, right, top to bottom. Commonly used are metal elastic sheets and rubber rings. For example, the patent 2022220512568 discloses a fault-tolerant windproof roller blind edge rail system without cloth clamping, which uses a metal elastic sheet for compression or rebound. For example, the patent 2022206458051 discloses a windproof roller blind edge rail system, which uses a rubber ring for compression or rebound. The metal elastic sheet has poor performance in resisting strong wind, low compression stress intensity, and easy to appear jamming phenomenon in rebound; the compression stress intensity of the rubber ring is also low, and it is easy to age and the rebound flexibility is poor after long-term use. The compression stress intensity and rebound smoothness of the elastic member directly affect the wind resistance and service life of the curtain cloth; in addition, the sharp end of the curtain cloth positioner also has friction to the curtain cloth during the installation and cloth arranging process, which has the risk of scratching and affects the service life of the curtain cloth after installation. Therefore, it is necessary to further develop and improve the components of the windproof roller blind edge rail system to improve the service performance and service life of the windproof roller blind. UTILITY MODEL CONTENTS

[0006] In the above technical solution, the curtain cloth positioner assembly 2 further includes a guide end, and the guide end is inserted into the end of the positioner 3.

[0007] In the above technical solution, the guide end is an arc surface port guide end 7, and the arc surface port guide end 7 is provided with an arc surface opening cloth port 7.1.

[0008] In the above technical solution, the guide end is a pulley guide end 8, and the pulley guide end 8 is provided with a flat cloth port, and two opposite pulleys 8.1 are arranged at the cloth port.

[0009] In the above technical solution, one end of the spring 6 is inserted and fixed to the plugboard 5.

[0010] In the above technical solution, after the edge rail system is assembled, the free end of the spring 6 is in contact with the inner wall of the curtain cloth pass-through port of the edge rail 1 in a natural state.

[0011] Compared with the prior art, the windproof curtain edge rail system has the following beneficial effects:

[0012] Firstly, the spring provides resilience, and the performance of resisting strong wind is better, the compression stress intensity is high, the spring rebounds smoothly, and the spring is not prone to aging, even if individual springs are aged, other springs can also provide sufficient elasticity, and the windproof curtain edge rail system is more suitable for long-term use.

[0013] Secondly, the conventional springback is installed on the edge rail, and the free end of the metal spring plate or the rubber ring is in contact with the positioner. The springback is directly installed on the positioner, and the free end of the spring is in contact with the edge rail. This design can ensure that the springback does not separate from the positioner, improve the structural stability, and facilitate the assembly and disassembly and maintenance of the spring.

[0014] Thirdly, the end of the curtain cloth positioner is inserted with a guide end, the guide end has a cloth guiding effect, the curtain cloth is installed more smoothly, the guide end does not scratch the curtain cloth, and the installation quality of the curtain cloth is ensured. In addition, the guide end with the pulley can also limit the curtain cloth from deviating when the curtain cloth is passed through.

[0015] Four, the curtain positioner assembly improves the structure and installation mode of the rebounder, the improvement increases the guide end head, can effectively improve the windproof performance and service life of the windproof roller shutter, has good practicability.
