Description

Technical Field

[0001] This utility model relates to the field of dust-free cable chain keel technology, specifically to dust-free cable chain aluminum alloy keel. Background Technology

[0002] In industrial automation, precision machinery, and clean environments such as semiconductor manufacturing, food processing, and pharmaceutical production, cable chains are key components that protect cables, oil pipes, and other pipelines and guide them as they move with the equipment. The performance of their keel structure directly affects the overall operational stability and service life of the equipment.

[0003] Currently, most cable chain keels on the market are made of plastic. Although they have certain advantages in terms of lightweight and low manufacturing cost, they have gradually revealed many shortcomings in practical applications:

[0004] Insufficient strength and rigidity: Plastic materials have limited load-bearing capacity. Under heavy pipeline loads or long-term high-frequency motion, they are prone to deformation and breakage, affecting the guiding accuracy and service life of the cable chain.

[0005] Poor sealing: The connection structure of plastic keel is mostly snap-fit ​​or simple splicing, with large gaps, making it difficult to effectively prevent dust, moisture and other impurities from entering the internal connection points, resulting in loose connections and corrosion. It is especially unsuitable for cleanroom environments with extremely high cleanliness requirements.

[0006] Low motion control precision: The individual connections of the plastic keel lack precise angle limiting structures, which can easily lead to excessive deformation or angle deviation during the bending and stretching of the cable chain, affecting the orderly layout of pipelines and the stable operation of equipment.

[0007] Therefore, it is necessary to design a dust-free cable chain aluminum alloy keel to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a dust-free cable chain aluminum alloy keel to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a dust-free cable chain aluminum alloy keel, including a sleeve, wherein a reinforcing mechanism is provided inside the sleeve;

[0010] The reinforcing mechanism includes a metal strip that is slidably connected inside a sleeve. A keel unit is slidably connected around the metal strip. A rivet is riveted inside the keel unit. A slanted groove is provided at the bottom right side of the keel unit.

[0011] Preferably, the sleeve has an installation cavity and a wire mounting cavity inside, and the metal strip and the keel unit are slidably connected in the installation cavity, which facilitates the installation of the metal strip through the installation cavity.

[0012] Preferably, the oblique grooves are provided in two sets and are symmetrically distributed on the bottom of the left and right sides of the keel body, so that the angle or curvature between the two keel bodies can be precisely limited through the grooves.

[0013] Preferably, the keel unit is made of aluminum alloy and is formed by metal stamping, which facilitates the improvement of the strength of the keel unit.

[0014] Preferably, the bottom of the rivet extends through the interior of the metal strip, which facilitates the use of the rivet to ensure stability between the metal strip and the keel unit.

[0015] Preferably, the sleeve includes a flexible layer, a buffer layer is fixedly connected to the periphery of the flexible layer, a reinforcing layer is fixedly connected to the periphery of the buffer layer, and a wear-resistant layer is fixedly connected to the periphery of the reinforcing layer.

[0016] Preferably, the innermost flexible layer is made of food-grade silicone, and the outermost wear-resistant layer is coated with a polytetrafluoroethylene coating. This allows the food-grade silicone to improve flexibility and resistance to high and low temperatures, while the polytetrafluoroethylene coating improves the coefficient of friction and provides excellent wear resistance.

[0017] Compared with the prior art, this utility model provides a dust-free cable chain aluminum alloy keel, which has the following beneficial effects:

[0018] 1. This dust-free cable chain features an aluminum alloy keel. Through a robust mechanism, the metal strip and keel units are slidably connected, and rivets penetrating the metal strip ensure a tight connection, enhancing the overall structural stability. The keel units are made of aluminum alloy and formed by metal stamping, guaranteeing high strength and rigidity to withstand certain loads. The stamping process also ensures structural consistency and precision, improving the overall quality of the keel. Symmetrically distributed oblique grooves on the bottom left and right sides of the keel units precisely limit the angle or curvature between two keel bodies. This design makes the relative movement of adjacent keel units more orderly and controllable during cable chain operation, avoiding malfunctions caused by excessive bending or angular deviations, and ensuring smooth cable chain operation. It is particularly suitable for scenarios requiring precise guidance and motion control.

[0019] 2. This dust-free cable chain features an aluminum alloy keel with a flexible layer, a buffer layer, a reinforcing layer, and a wear-resistant layer. The innermost flexible layer is made of food-grade silicone, offering excellent flexibility and resistance to high and low temperatures. It provides gentle protection for internal cables and components and meets food-grade standards, making it suitable for applications with high environmental requirements. The buffer layer is made of modified polyethylene, possessing excellent cushioning and shock absorption properties. It primarily serves as a buffer and support layer. The modified polyethylene exhibits superior flexibility, adapting flexibly to the bending motion of the cable chain, reducing the pulling force on the internal Teflon layer. Furthermore, this material has good impact resistance, reducing the impact of the external environment on the internal casing. It also possesses strong chemical stability, making it less prone to producing volatiles and particles. Meeting the requirements of a cleanroom environment, the reinforcing layer is made of polyimide film, which has excellent mechanical strength and temperature resistance, providing structural stability to the casing and enhancing its overall tensile and tear resistance. Its dense surface and poor air permeability effectively prevent external microparticles from entering the casing, further improving its dustproof performance. In addition, the thin polyimide film does not excessively increase the weight and volume of the casing, ensuring the flexibility of the cable chain movement. The outermost wear-resistant layer is a sprayed polytetrafluoroethylene coating. Polytetrafluoroethylene has an extremely low coefficient of friction and excellent wear resistance, making the casing less prone to wear during long-term use and contact with other components, greatly enhancing the durability of the casing and reducing maintenance costs.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-6 This utility model provides a technical solution: a dust-free cable chain aluminum alloy keel, including a sleeve 1, and a reinforcing mechanism 2 is provided inside the sleeve 1;

[0033] The reinforcing mechanism 2 includes a metal strip 21, which is slidably connected to the sleeve 1. A keel unit 22 is slidably connected to the outer periphery of the metal strip 21. A rivet 24 is riveted inside the keel unit 22. A slanted groove 23 is provided at the bottom right side of the keel unit 22.

[0034] The sleeve 1 has an installation cavity and a wire mounting cavity inside. The metal strip 21 and the keel unit 22 are slidably connected in the installation cavity, which facilitates the installation of the metal strip 21 through the installation cavity.

[0035] Two sets of oblique grooves 23 are provided and symmetrically distributed on the bottom of the left and right sides of the keel body 22, so that the position angle or curvature between the two keel bodies can be precisely limited through the grooves.

[0036] The keel unit 22 is made of aluminum alloy and is formed by metal stamping, which makes it easier to improve the strength of the keel unit 22.

[0037] The bottom of the rivet 24 extends through the interior of the metal strip 21, which facilitates the stability between the metal strip 21 and the keel unit 22.

[0038] Example 2

[0039] Please see Figure 1-6 Furthermore, based on Example 1, the sleeve 1 includes a flexible layer 3, a buffer layer 4 is fixedly connected to the periphery of the flexible layer 3, a reinforcing layer 5 is fixedly connected to the periphery of the buffer layer 4, and a wear-resistant layer 6 is fixedly connected to the periphery of the reinforcing layer 5.

[0040] The flexible layer 3 is the innermost layer and is made of food-grade silicone. The wear-resistant layer 6 is the outermost layer and is coated with polytetrafluoroethylene. The food-grade silicone material is used to improve flexibility and resistance to high and low temperatures, while the polytetrafluoroethylene coating improves the coefficient of friction and excellent wear resistance.

[0041] In actual operation, when this device is used, the keel unit 22 is first slidably connected to the outside of the metal strip 21, and at the same time riveted to the inside of the keel unit 22 and the metal strip 21 by rivets 24 to ensure the stability between the two. After the keel unit 22 is installed on the outside of the metal strip 21, the metal strip 21 can be slidably connected to the installation cavity in the sleeve 1. The keel unit 22 is made of aluminum alloy and is formed by metal stamping, which not only ensures that it has high strength and rigidity and can withstand a certain load, but also achieves structural consistency and precision through the stamping process, thus improving the overall quality of the keel.

[0042] The symmetrically distributed oblique grooves 23 on the bottom of the left and right sides of the keel unit 22 can precisely limit the position angle or curvature between the two keel bodies. This design makes the relative movement of adjacent keel units 22 more orderly and controllable during the movement of the cable chain, avoiding failures caused by excessive bending or angle deviation, ensuring the smooth operation of the cable chain, and is especially suitable for scenarios that require precise guidance and motion control.

[0043] The innermost flexible layer 3 is made of food-grade silicone, possessing excellent flexibility and resistance to high and low temperatures. It provides gentle protection for internal cables and components and meets food-grade standards, making it suitable for applications with high environmental requirements. The buffer layer 4 is made of modified polyethylene, exhibiting excellent cushioning and shock absorption performance. It primarily serves as a buffer and support layer. The modified polyethylene offers even greater flexibility, adapting flexibly to the bending motion of the cable chain, reducing the pulling force on the internal Teflon layer. Simultaneously, this material exhibits good impact resistance, minimizing the impact of the external environment on the interior of the sleeve 1. Furthermore, its strong chemical stability prevents the generation of volatiles and particles, meeting the requirements for cleanroom environments. The reinforcing layer 5 is made of polyimide. The amine film material possesses excellent mechanical strength and temperature resistance, providing a certain degree of structural stability to the sleeve 1 and enhancing its overall tensile and tear resistance. Its dense surface and poor air permeability effectively prevent external microparticles from entering the sleeve 1, further improving its dustproof performance. In addition, the thin polyimide film does not excessively increase the weight and volume of the sleeve 1, ensuring the flexibility of the cable chain movement. The outermost wear-resistant layer 6 is a sprayed polytetrafluoroethylene coating. Polytetrafluoroethylene has an extremely low coefficient of friction and excellent wear resistance, making the sleeve 1 less prone to wear during long-term use and contact with other components, greatly enhancing its durability and reducing maintenance costs.
