Description

Technical Field

[0001] The utility model relates to the field of ladder belts, in particular to a casing type louver ladder belt. Background Art

[0002] As a common sunshade, ventilation and decorative 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 belt, 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 belt 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, and its importance is self-evident.

[0003] The existing louver ladder belts usually consist of multiple parallel longitudinal belts and horizontal grid lines connecting these longitudinal belts. Longitudinal stitching lines are provided on these longitudinal belts to enhance the strength and stability of the ladder belt. The horizontal grid lines are connected to the longitudinal belts through specific weaving or stitching processes to form a stable support structure. In practical applications, the ladder belt 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] Chinese Patent with Publication No. CN2813856Y discloses a ladder pull rope and a louver using the ladder pull rope. The ladder pull rope includes two ladder ropes, and fixing ropes for fixing the blades are arranged at intervals between the two ladder ropes. A plurality of loops integrally formed with each ladder rope are arranged at intervals on each ladder rope, and a pull rope is inserted through the loops on the two ladder ropes, making its structure simple and easy to install.

[0005] Chinese Patent with Publication No. CN 209547753 U discloses a Roman blind safety rope. The Roman blind safety rope includes a pull rope, and a protective mesh is sleeved outside the pull rope. A pull rope cavity and a fixing rope cavity are arranged inside the protective mesh. The pull rope passes through the inside of the pull rope cavity, and the pull rope can be freely pulled in the pull rope cavity. A fixing rope is inserted into the fixing rope cavity. By using the protective mesh to wrap the pull rope and the fixing rope inside it, it can prevent children from pulling the pull rope with their fingers and prevent the pull rope from stretching too long and winding around a child's head.

[0006] However, the drawstrings of the prior art are generally directly exposed outside the shutter structure. When someone pulls the drawstring manually, the safety distance will be widened. When a child pulls the drawstring manually, it is easy to strangle the child's head, which poses a safety hazard in the use of the shutter ladder belt. In addition, the existing shutter ladder belt protects the drawstring by setting up a protective screen to prevent manual pulling. However, the existing protective screen and the ladder belt are generally installed separately. The protective screen needs to be installed and fixed to the external structure, making the installation structure of the shutter complex, resulting in cumbersome installation operations, thus affecting the installation convenience of the shutter and the ladder belt and being not conducive to use. Summary of the Invention

[0007] The purpose of the present invention is to solve the above defects and provide a sleeve-type shutter ladder belt to solve the technical problems that the use of the existing drawstring in the above background technology has safety hazards, and the structure of the existing drawstring protection structure is complex, affecting the installation convenience, and thus being not conducive to use.

[0008] The purpose of the present invention is achieved in the following way:

[0009] The sleeve-type shutter ladder belt includes a drawstring and two ladder ropes. An installation part for installing shutter blades is arranged between the two ladder ropes. The installation part is distributed along the length direction of the ladder ropes. A wrapping net is sleeved outside the drawstring. The wrapping net is formed into a woven tubular shape with a hollow interior through weaving, so that a through hole for threading the drawstring is formed inside the wrapping net. The wrapping net is sleeved outside the drawstring through the through hole, enabling the drawstring to move along the through hole of the wrapping net. Hanging ears are arranged on the ladder ropes. One end of the hanging ear on the ladder rope penetrates into the wrapping net through weaving, so that the ladder rope is connected to the wrapping net through the hanging ear.

[0010] Further in the above description, the drawstring is threaded through the through hole of the wrapping net, and one end of the drawstring passes through the through hole and extends outward from the wrapping net.

[0011] Specifically, the wrapping net wraps the drawstring through the through hole, making it difficult for the drawstring to be locally pulled and causing the safety distance after pulling to entangle and strangle the child's head. In addition, one end of the drawstring is exposed outside the wrapping net, so that the operation can be conveniently carried out through the drawstring.

[0012] Further in the above description, the outer surface of the wrapping net is woven to form woven mesh holes. One end of the ladder rope passes through the woven mesh holes of the wrapping net through the hanging ear and is connected in a closed loop with the ladder rope, connecting the wrapping net to the ladder rope.

[0013] Specifically, the woven wrapping net endows it with certain tensile ductility, so that it can be wrapped around the drawstring. The woven mesh holes formed by weaving are used to connect with the hanging ears of the ladder rope, which can facilitate the fixation of the wrapping net. And by pre-connecting the wrapping net with the ladder rope, the subsequent assembly of the shutter is made more convenient and rapid.

[0014] Further in the above description, the hanging ears are spaced along the length direction of the ladder rope, and a safety distance is formed between two adjacent hanging ears.

[0015] Further in the above description, the installation part is composed of two horizontal installation ropes, and an installation gap for installing the shutter blades is formed between the two horizontal installation ropes. The connection of the installation part with the two ladder ropes forms a ladder grid shape.

[0016] Further in the above description, both the wrapping net and the ladder rope are formed by weaving.

[0017] The beneficial effects of the present utility model: The drawstring is sleeved inside the woven wrapping net. The through-hole design inside the wrapping net ensures that the drawstring can move freely and smoothly. Thus, the woven wrapping net can further enhance the protection effect on the drawstring, and the wrapping protection of the drawstring by the wrapping net makes it difficult for the drawstring to be pulled too long and entangle children when there is a child's tugging, reducing the safety hazard caused by the entanglement of the drawstring. And the hanging ears provided on the ladder rope are woven into the wrapping net to achieve a firm connection between the wrapping net and the ladder rope, completing the connection between the wrapping net and the ladder rope during the production process, simplifying the subsequent installation steps of the wrapping net and external connectors, reducing the need for additional connectors, improving the convenience of installation operations. At the same time, the woven connection improves the stability at the connection of the wrapping net and the ladder rope, reducing problems such as loosening and falling off, ensuring the stability and reliability of the overall structure of the shutter ladder belt.

[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] In this embodiment, referring to Figures 1-4 , the specifically implemented casing-type louver ladder belt includes a pull rope 1 and two ladder ropes 2. An installation part 3 for installing louver blades 8 is arranged between the two ladder ropes 2. The installation part 3 is distributed along the length direction of the ladder rope 2. A wrapping net 4 is sleeved outside the pull rope 1. The wrapping net 4 is formed into a woven tubular shape with a hollow interior by weaving, so that a through hole 5 for threading the pull rope 1 is formed inside the wrapping net 4. The wrapping net 4 is sleeved outside the pull rope 1 through the through hole 5, enabling the pull rope 1 to stretch or contract along the through hole 5 of the wrapping net 4. Hanging ears 6 are arranged on the ladder rope 2. One end of the hanging ear 6 on the ladder rope 2 penetrates into the wrapping net 4 through weaving, so that the ladder rope 2 is connected to the wrapping net 4 through the hanging ear 6.

[0025] The pull rope 1 is threaded through the through hole 5 of the wrapping net 4, and one end of the pull rope 1 penetrates through the through hole 5 and extends outward to the outside of the wrapping net 4. Specifically, the wrapping net 4 wraps the pull rope 1 through the through hole 5, making it difficult for the pull rope 1 to have a phenomenon where the safety distance after local pulling is wound around a child's head, and one end of the pull rope 1 is exposed outside the wrapping net 4, so that the operation can be conveniently performed through the pull rope 1.

[0026] The outer surface of the wrapping net 4 is woven to form woven mesh holes 7. One end of the hanging ear 6 on the ladder rope 2 penetrates into the woven mesh holes 7 of the wrapping net 4 and is connected to the ladder rope 2 in a closed loop, connecting the wrapping net 4 to the ladder rope 2. Specifically, the woven wrapping net 4 has a certain stretching ductility, so that it can be wrapped around the pull rope 1. The woven mesh holes 7 formed by weaving are used to connect with the hanging ears 6 of the ladder rope 2, so that the wrapping net 4 can be conveniently fixed, and by pre-connecting the wrapping net 4 with the ladder rope 2, the subsequent assembly of the louver is made more convenient and rapid.

[0027] The hanging ears 6 are spaced along the length direction of the ladder rope 2, and a safety distance is formed between two adjacent hanging ears 6. Specifically, the hanging ears 6 are arranged in an equidistant array along the length direction of the ladder rope 2, and the hanging ears 6 are connected to the wrapping net 4 in a circular ring shape.

[0028] The installation part 3 is composed of two horizontal installation ropes, and an installation gap for installing the louver blades 8 is formed between the two horizontal installation ropes. The connection between the installation part 3 and the two ladder ropes 2 forms a ladder grid shape. Both the wrapping net 4 and the ladder rope 2 are formed by weaving.

[0029] The specific installation structure in this embodiment is:

[0030] The ladder ropes 2 are formed by weaving, and the two ladder ropes 2 are connected by the mounting parts 3. The mounting parts 3 are arranged in an equidistant array along the length direction of the ladder ropes 2, and are connected by passing the hanging ears 6 through some of the woven mesh holes 7 of the wrapping net 4, so that the wrapping net 4 is connected to the ladder ropes 2. The pulling rope 1 is passed through the through holes 5 of the wrapping net 4, thus completing the installation of the ladder belt. By providing two ladder belts, the mounting parts 3 of the two ladder belts are connected to the blades 8, so that the two ladder belts are respectively installed at one end of the blades 8 and are connected to the lifting control mechanism 9 of the shutter. The expansion and contraction of the blades 8 can be controlled by the pulling rope 1 and the lifting control mechanism 9, and the opening or closing of the blades 8 can be controlled by the rotation adjustment on the lifting control mechanism 9, thereby completing the control and use of the shutter;

[0031] Among them, the pulling rope 1 is sleeved and arranged inside the woven wrapping net 4. The design of the through holes 5 inside the wrapping net 4 ensures that the pulling rope 1 can move freely and smoothly. The woven wrapping net 4 can further enhance the protection effect on the pulling rope 1 and the wrapping protection of the pulling rope 1 by the wrapping net 4, so that when a child pulls it, it is not easy to cause the pulling rope 1 to be pulled too long and entangle the child, reducing the potential safety hazard caused by the entanglement of the pulling rope 1;

[0032] In addition, the hanging ears 6 provided on the ladder ropes 2 are inserted into the wrapping net 4 by weaving, realizing the firm connection between the wrapping net 4 and the ladder ropes 2, so that the connection between the wrapping net 4 and the ladder ropes 2 is completed during the production process, simplifying the subsequent installation steps of the wrapping net 4 and external connectors and reducing the need for additional connectors, improving the convenience of installation operations. At the same time, the woven connection improves the stability at the connection between the wrapping net 4 and the ladder ropes 2, reducing problems such as loosening and falling off, and ensuring the stability and reliability of the overall structure of the shutter ladder belt.
