Description

Technical Field

[0001] This utility model relates to the field of protective curtain technology, specifically an aluminum-material-insulated fabric protective curtain. Background Technology

[0002] Aluminum-lined fabric protective curtain is a foldable protective screen made of aluminum alloy profile as frame and high-strength flame-retardant fabric sandwiched in the middle. It retains the rigidity, corrosion resistance and heat dissipation of aluminum material, while the fabric layer absorbs sparks and blocks ultraviolet rays and smoke. It is often used around high-speed rail conductive rails, welding stations or laser cutting equipment to achieve lightweight, high temperature resistance and easy quick deployment and retraction of flexible safety isolation. During the installation and bonding of aluminum plates and fabric, if the pressure applied to both is too great, it will cause irreversible and serious damage to the internal fiber structure of the fabric. This excessive pressure will not only directly cause the fabric fibers to break, but also destroy the original stable connection between the fibers, thereby damaging the overall structural integrity of the fabric and significantly reducing the toughness of the fabric itself. Therefore, in order to address the above problems, an aluminum-clad fabric protective curtain is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide an aluminum-material-insulated fabric protective curtain to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A protective curtain made of aluminum material with fabric reinforcement includes a three-proof fabric and pre-drilled holes. The three-proof fabric is sandwiched between a first aluminum plate assembly and a second aluminum plate assembly. A blocking component is internally threaded onto the second aluminum plate assembly. The first aluminum plate assembly includes a first aluminum plate with a first circular hole, a second circular hole, and a pressure-distributing surface on its inner side. The second aluminum plate assembly includes a second aluminum plate with a screw hole on its inner side. An assembly head is fixedly connected to the upper end of the second aluminum plate near the screw hole. The upper surface of the assembly head has a first arc surface, and the lower surface of the assembly head near the first arc surface has a second arc surface. Deformation grooves are formed on both sides of the assembly head.

[0005] As a further optimization of this utility model, the following features are provided: a pre-drilled hole is provided on the inner side of the three-proof cloth, an assembly head is inserted into the inner side of the pre-drilled hole, and the lower surface of the three-proof cloth is attached to the upper surface of the second aluminum plate.

[0006] As a further optimization of this utility model, the diameter of the second circular hole is 1.1 times the diameter of the upper surface of the first arc surface. The first aluminum plate is fitted onto the outer side of the first arc surface through the second circular hole. The first aluminum plate deforms the assembly head by pressing the first arc surface through the second circular hole.

[0007] As a further optimization of this utility model, the deformation groove provides space for the deformation of the assembly head, the assembly head is pressed through the first circular hole in the first aluminum plate by the first arc surface, and the second arc surface of the assembly head is in contact with the pressure dividing surface.

[0008] As a further optimization of this utility model, the blocking component includes a stop post, a screw is fixedly connected to the bottom end of the stop post, an operating head is fixedly connected to the top end of the stop post, and the shape of the stop post matches the inner shape of the assembly head.

[0009] As a further optimization of this utility model, the screw is threadedly connected to the screw hole, the screw is embedded inside the screw hole, the stop post is embedded inside the assembly head, and the outer side of the stop post fits against the inner side of the assembly head.

[0010] As a further optimization of this utility model, the top end of the assembly head is flat, and there is a clearance fit between the top end of the assembly head and the bottom end of the operating head.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the device, with its first aluminum plate assembly, blocking assembly, and second aluminum plate assembly, requires no additional adjustment by personnel. The pressure of the three-proof cloth being bonded to the aluminum plate can be precisely controlled within a reasonable range through the deformation and compression of the components themselves. This effectively avoids excessive compression due to misoperation, prevents the internal fibers of the cloth from breaking and the structural integrity from being damaged, and ensures that the toughness of the cloth is not affected.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A protective curtain made of aluminum material with fabric sandwiched between two types of protective fabric 1 and pre-drilled holes 2. The protective fabric 1 is sandwiched between a first aluminum plate assembly 3 and a second aluminum plate assembly 5. A blocking component 4 is internally threaded onto the second aluminum plate assembly 5. The first aluminum plate assembly 3 includes a first aluminum plate 31. A first round hole 32, a second round hole 33, and a pressure-distributing surface 34 are provided on the inner side of the first aluminum plate 31. The second aluminum plate assembly 5 includes a second aluminum plate 51. A screw hole 52 is provided on the inner side of the second aluminum plate 51. An assembly head 53 is fixedly connected to the upper end of the second aluminum plate 51 near the screw hole 52. A first arc surface 54 is provided on the upper end face of the assembly head 53. A second arc surface 55 is provided on the lower end face of the assembly head 53 near the first arc surface 54. Deformation grooves 56 are provided on the left and right sides of the assembly head 53.

[0017] As a further implementation of this solution, a pre-drilled hole 2 is provided on the inner side of the three-proof cloth 1. An assembly head 53 is inserted into the inner side of the pre-drilled hole 2. The lower surface of the three-proof cloth 1 is attached to the upper surface of the second aluminum plate 51. Through the above settings, the nylon fiber three-proof cloth and the aluminum plate can be quickly positioned and aligned, laying the foundation for subsequent precise pressure bonding, ensuring that the bonding surface is flat and without deviation, and avoiding damage to the cloth due to uneven local pressure caused by misalignment. As a further implementation of this solution, the diameter of the second circular hole 33 is 1.1 times the diameter of the upper surface of the first arc surface 54. The first aluminum plate 31 is fitted onto the outside of the first arc surface 54 through the second circular hole 33. The first aluminum plate 31 is squeezed onto the first arc surface 54 through the second circular hole 33, causing the assembly head 53 to deform. Through the above arrangement, the first aluminum plate 31 can be fitted onto the assembly head 53, realizing the controllable deformation of the assembly head 53, ensuring that its deformation force acts stably on the first aluminum plate 31, thereby accurately controlling the pressure on the three-proof cloth 1 at 0.2–0.3 MPa, avoiding excessive compression that damages the fiber structure of the cloth. As a further implementation of this solution, the deformation groove 56 provides space for the deformation of the assembly head 53. The assembly head 53 extrudes the first circular hole 32 of the first aluminum plate 31 through the first arc surface 54. The second arc surface 55 of the assembly head 53 is in contact with the pressure dividing surface 34. Through the above settings, sufficient buffer space can be provided for the deformation of the assembly head 53. At the same time, the contact between the second arc surface 55 and the pressure dividing surface 34 forms a stable pressure transmission path, ensuring that the extrusion pressure on the three-proof cloth 1 is uniform and continuous, and maintaining the integrity and toughness of the cloth structure. As a further implementation of this solution, the blocking component 4 includes a stop post 41, with a screw 43 fixedly connected to the bottom end of the stop post 41 and an operating head 42 fixedly connected to the top end of the stop post 41. The shape of the stop post 41 matches the inner shape of the assembly head 53. Through the above settings, the stop post 41 and the inner side of the assembly head 53 can be tightly fitted, providing a structural basis for the subsequent fixing of the assembly head 53, avoiding unstable pressure transmission due to assembly gaps, and ensuring pressure application accuracy. As a further implementation of this solution, the screw 43 is threadedly connected to the screw hole 52, the screw 43 is embedded inside the screw hole 52, and the stop post 41 is embedded inside the assembly head 53, with the outer side of the stop post 41 fitting against the inner side of the assembly head 53. Through the above arrangement, the deformation state of the assembly head 53 can be firmly locked by the threaded connection, preventing the assembly head 53 from springing back or shifting during use, which would cause the extrusion pressure to fail. At the same time, it prevents the device from falling apart and ensures that the pressure on the three-proof cloth 1 remains stable within a reasonable range for a long time. As a further implementation of this solution, the top of the assembly head 53 is flat, and there is a gap fit between the top of the assembly head 53 and the bottom of the operating head 42. Through the above setting, a buffer space for assembly and deformation can be reserved to avoid abnormal deformation of the assembly head 53 caused by hard collision between the operating head 42 and the top of the assembly head 53 during installation. At the same time, it does not affect the fixing effect of the stop column 41 on the assembly head 53, ensuring the assembly stability and pressure accuracy of the overall device.

[0018] Workflow: During installation, the pre-drilled holes 2 of the three-proof cloth 1 are fitted onto the outside of the assembly head 53, so that the three-proof cloth 1 is laid on the upper end of the second aluminum plate 51 and adheres to the upper end of the second aluminum plate 51. After multiple second aluminum plates 51 and three-proof cloth 1 are installed, the first aluminum plate 31 is then assembled with the assembly head 53, with the second round hole 33 of the first aluminum plate 31 facing downwards. When the two second round holes 33 of the first aluminum plate 31 are aligned with the two assembly heads 53 on the same second aluminum plate 51, the distance from the left end to the right end of the assembly head 53 is equal to the diameter of the second round hole 33. This is 0.9 times the size of the first aluminum plate 31, allowing the assembly head 53 to be embedded inside the second circular hole 33. The first aluminum plate 31 is pressed downwards, and through the compression of the first arc surface 54 by the first aluminum plate 31, the shape of the first arc surface 54 is an arc-shaped slope. After being subjected to force on the first arc surface 54, the assembly head 53 is deformed under pressure, deforming towards the deformation groove 56. When the second circular hole 33 passes the first arc surface 54, the upper end of the second circular hole 33 will contact the second arc surface 55. At this time, under the action of the assembly head 53 restoring its shape, the second arc surface 55 compresses the upper end of the second circular hole 33. Over-extrusion forces the first aluminum plate 31 towards the three-proof cloth 1. At this time, the lower surface of the second arc surface 55 is in contact with the pressure dividing surface 34. The protrusion at the upper end of the assembly head 53 is inside the first circular hole 32. The rated deformation force of the assembly head 53 pushes the first aluminum plate 31 and, with the assistance of the second aluminum plate 51, extrudes the three-proof cloth 1. The material of the three-proof cloth 1 is nylon fiber three-proof cloth. The deformation force of the assembly head 53 controls the pressure of the three-proof cloth 1 to be controlled at 0.2–0.3 MPa. Then, the stop post 41 and the operating head 42 are inserted into the assembly head 53. By turning the operating head 42 with a screwdriver, the screw... Rod 43 is threaded into screw hole 52 until operating head 42 is difficult to rotate. At this time, the outer side of stop post 41 fits against the inner side of assembly head 53. By blocking assembly head 53 through stop post 41, the assembly head 53 is prevented from falling off due to deformation during use. Based on the above principle, when assembling aluminum plate and cloth, the device can prevent excessive compression force on the three-proof cloth 1 due to misoperation. This installation method does not require adjustment by staff. The compression force of the three-proof cloth 1 can be controlled within a reasonable range through its own deformation and compression, ensuring that the fibers of the three-proof cloth 1 will not break or be damaged and that its toughness will not be affected.
