Description

Technical Field

[0001] The utility model relates to the field of webbing, in particular to a traction webbing for movable louvers. Background Art

[0002] As a common sunshade, ventilation and decoration component, louvers have a wide range of applications. Their unique blade design can not only adjust the light and ventilation volume, but also effectively protect indoor privacy. The louver ladder tape, as an important part of the louver, mainly undertakes the functions of connecting, supporting and adjusting the louver blades, and is a key component to ensure the normal operation of the louver. Specifically, the louver ladder tape has a wide range of applications, including but not limited to various occasions such as communities, villas, factories, schools, hospitals, shopping malls, office buildings, office buildings, municipal facilities and public facilities. Its importance is self-evident.

[0003] The existing louver ladder tape usually consists of multiple parallel longitudinal tapes and cross grid lines connecting these longitudinal tapes. Longitudinal sewing lines are provided on these longitudinal tapes to enhance the strength and stability of the ladder tape. The cross grid lines are connected to the longitudinal tapes through specific weaving or sewing processes to form a stable support structure. In practical applications, the ladder tape orderly connects the louver blades through its unique structure, and realizes the flipping and angle adjustment of the blades through an adjustment mechanism, so as to meet different sunshade, ventilation and privacy protection requirements.

[0004] However, the existing pull ropes are usually divided into those internally threaded through the blades or arranged on the sides of the blades. For the pull ropes externally arranged outside the blades, protective mesh is provided for wrapping and protection. While the existing pull ropes internally threaded through the blades are generally directly exposed outside the louver structure. When there is artificial pulling of the pull rope, the pull rope easily forms a sleeve hole when stretching through the safety distance between two adjacent blades. And when there is artificial pulling by children, it is easy to strangle the heads of children, which poses a safety hazard in the use of the louver ladder tape and affects the safe use of the louver traction webbing. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above defects, and provide a traction webbing for movable louvers, so as to solve the technical problem that the exposed structure of the pull rope threaded through the louver blades in the above background art easily expands to generate a safety hazard of sleeve holes under stretching, affecting the use safety.

[0006] The purpose of the utility model is achieved in the following way:

[0007] The traction webbing for movable louvers includes a drawstring and two woven ladder tapes. The two woven ladder tapes are connected by weaving and form a connecting part for installing louver blades. A sheathing net is sleeved outside the drawstring. The sheathing net is woven to form a conducting socket hole inside. The sheathing net is sleeved and wrapped outside the drawstring through the socket hole, so that the drawstring passes through the socket hole, and the drawstring can be adjusted axially along the sheathing net. The end of the drawstring passes through the socket hole and extends outwards.

[0008] Further in the above description, the connecting part is composed of several connecting ropes. The installation ropes are woven between the two ladder tapes, so that the two ladder tapes are connected by the connecting ropes.

[0009] Further in the above description, the connecting ropes are spaced along the length direction of the two ladder tapes, so that the connection between the connecting ropes and the two ladder tapes forms a ladder grid shape, and an installation spacing for installing louver blades is formed between two adjacent connecting ropes.

[0010] Further in the above description, the sheathing net is made by weaving with woven ropes. The sheathing net is used for stringing louver blades, and a friction surface for contacting the louver blades is formed on the outer surface of the sheathing net.

[0011] Specifically, the sheathing net wraps the drawstring through the socket hole, so that the sheathing net passes through the through hole on the blade to form an internal installation. This internal installation makes it difficult for the drawstring to be locally pulled and cause the safety spacing to be wound around a child's head. And when the sheathing net is pulled, the outer surface of the sheathing net contacts the through hole of the blade to form a friction surface, further improving the pulling force of the drawstring when stretched outwards, and then slowing down the stretching phenomenon of the drawstring passing through the safety spacing under pulling or tugging.

[0012] Further in the above description, the drawstring, the sheathing net and the ladder tapes are all composed of weaving.

[0013] The beneficial effects of the present utility model: The drawstring is sleeved in the woven sheathing net. The socket hole design in the sheathing net enables the drawstring to be stretched axially along the socket hole. And the woven sheathing net can further enhance the protection effect on the drawstring. The sheathing net wraps and protects the drawstring, so that when a child tugs, it is not easy for the drawstring to be pulled too long and wind around the child. And the sheathing net passes through the louver blades to form an internal installation. When the sheathing net is pulled, due to the contact between the sheathing net and the louver blades, a certain frictional force is generated, thereby increasing the pulling force required for tugging, making it difficult for a child to easily stretch the drawstring, thus reducing the safety hazard of the drawstring winding and ensuring the stability and reliability of the overall structure of the louver traction webbing.

[0018] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific implementation modes.

[0019] In this embodiment, referring to Figures 1-3 , the traction webbing for the movable louver specifically implemented in this embodiment includes a pull rope 1 and two woven ladder belts 2. The two woven ladder belts 2 are connected by weaving and form a connecting part 3 for installing the louver blades 7. A socket net 4 is sleeved outside the pull rope 1. The socket net 4 is woven to form a conductive socket hole 5 inside. The socket net 4 is sleeved and wrapped outside the pull rope 1 through the socket hole 5, so that the pull rope 1 passes through the socket hole 5, and the pull rope 1 can be adjusted axially along the socket net 4. The end of the pull rope 1 extends out through the socket hole 5.

[0020] In this embodiment, the connecting part 3 is composed of connecting ropes. The installation ropes are woven between the two ladder belts, so that the two ladder belts are connected by the connecting ropes. The connecting ropes are distributed at intervals along the length direction of the two ladder belts, so that the connection between the connecting ropes and the two ladder belts forms a ladder grid shape, and an installation spacing 6 for installing the louver blades 7 is formed between two adjacent connecting ropes.

[0021] Specifically, the connecting ropes are connected to the blades 7, so that the blades 7 are folded or unfolded under the drive of stretching.

[0022] In this embodiment, the socket net 4 is made by weaving with a braided rope. The socket net 4 is used for connecting the louvre blades 7 in series, and a friction surface for contacting the louvre blades 7 is formed on the outer surface of the socket net 4. Specifically, the socket net 4 wraps the pull rope 1 through the socket holes 5, so that the socket net 4 is internally installed through the through holes 8 on the blades 7. This internal installation makes it difficult for the pull rope 1 to have the phenomenon that the safety distance after local pulling is wound around a child's head. And when the socket net 4 is pulled, the outer surface of the socket net 4 contacts the through holes 8 of the blades 7 to form a friction surface, further increasing the pulling force of the pull rope 1 being stretched outwards, and then slowing down the stretching phenomenon of the pull rope 1 passing through the safety distance under pulling or tugging.

[0023] In this embodiment, the pull rope 1, the socket net 4 and the ladder belt are all formed by weaving.

[0024] The specific installation structure in this embodiment is as follows: One end of the pull rope 1 passes through the through hole 8 of the blade 7 and is connected, and the other end of the pull rope 1 is connected to an external lifting control mechanism and is exposed outside the louvre, so that the expansion and contraction of the blade 7 can be controlled through the pull rope 1. Among them, the connection end of the pull rope 1 and the blade 7 is sleeved inside the woven socket net 4. The socket holes 5 inside the socket net 4 are designed to enable the pull rope 1 to stretch axially along the socket holes 5. And the woven socket net 4 can further enhance the protection effect on the pull rope 1. The wrapping and protection of the socket net 4 on the pull rope 1 makes it difficult for the pull rope 1 to be pulled too long and wind around a child when a child tugs the pull rope 1 from two adjacent blades 7. And the socket net 4 is installed inside the louvre blades 7 to form an internal installation. When the socket net 4 is pulled, due to the contact between the socket net 4 and the through holes 8 of the louvre blades 7, a certain frictional force is generated, thereby increasing the pulling force required for tugging, so that the tugging of a child will not easily cause stretching, thus reducing the safety hazard of the winding of the pull rope 1 and ensuring the stability and reliability of the overall structure of the traction webbing.
