Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust-free cable chain fixing technology, and in particular to a dust-free cable chain anti-loosening fixing device. Background Technology
[0002] Cleanroom cable chains are cable chain systems specifically designed for cleanrooms or clean environments. They are mainly used to protect equipment such as cables and hoses while ensuring a dust-free and pollution-free working environment. In recent years, they have been increasingly used in various fields.
[0003] To prevent multiple cables on a cleanroom cable chain from becoming tangled and messy during use, bundling tools such as vinyl tape, cable ties, and cable ropes are typically used for binding and covering. However, when using vinyl tape to bundle multiple cables, the tape needs to be wrapped around the cables, making the bundling work difficult. Furthermore, the tape must be torn off before the cables can be untied. Additionally, when releasing the tape, the sticky residue remains on the cables, and dust adheres to the wires, resulting in poor appearance, non-reusability, and failure to meet cleanroom environment requirements. When using cable ties, the bundling and untying of cables is difficult, the ties can be cut with pliers or a cutter when releasing the cables, and the ties cannot be reused.
[0004] Therefore, there is a need to provide a dust-free cable chain anti-loosening fixing device to solve the above problems. Utility Model Content
[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a dust-free cable chain anti-loosening fixing device that meets the requirements for cable use in a dust-free environment, facilitates cable bundling and disassembly, and can be reused.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a dust-free cable chain anti-loosening fixing device, including a fixing strap; the two ends of the fixing strap along its length are respectively provided with a first joint and a second joint, the first joint and the second joint are detachably joined by a joint structure that cooperates with each other, so as to bundle and cover the cable in the fixing strap, the fixing strap includes an outer protective layer and an inner protective layer, both of which are made of ePTFE material.
[0007] Furthermore, the outer protective layer and the inner protective layer are connected and fixed together by an adhesive layer. The adhesive layer is elastic and, after adhering to the outer and inner protective layers made of ePTFE material, forms a flexible fixing strap, ensuring that the fixing strap will not break during the process of bundling the cable.
[0008] Furthermore, the first joint has a plurality of female buckles, and the second joint has a plurality of male buckles that match the number and position of the female buckles. The female buckles and male buckles can be elastically engaged to bundle and fix the cable.
[0009] The male buckle includes a protruding locking post, and the female buckle has a locking groove that matches the locking post, so that the user can quickly fix or remove the cable at both ends of the fixing strap.
[0010] Furthermore, the engaging ends of both the male and female buckles are located on the inner protective layer.
[0011] Furthermore, the engaging end of one of the male and female buckles is located on the inner protective layer, while the engaging end of the other is located on the outer protective layer. After the cable is bundled, compared to placing the engaging ends of the male and female buckles on the same side, the appearance is more aesthetically pleasing and occupies less space while maintaining the same bundling stability.
[0012] Furthermore, several of the aforementioned female or male clips are arranged in an array at intervals. The male clip can be selected to press the position of the female clip to accommodate the bundling and fixing of cables of different numbers or diameters.
[0013] Furthermore, the engagement structure on the first joint is a D-ring or D-pin buckle, while the engagement structure on the second joint is the end of a securing strap. This belt-like buckle structure allows users to quickly and easily bundle and secure cables on the cable chain, simplifying operation and facilitating subsequent cable removal.
[0014] Furthermore, the end of the fixing strap has several through holes along its length that match the pins on the D-ring buckle. This ensures that the cable is securely bound and the fixing strap will not easily loosen, guaranteeing the stability of the cable binding.
[0015] The beneficial effects of this utility model are:
[0016] 1. In this utility model, the fixing strap, the first joint and the second joint set at both ends of the fixing strap, and the joint structure cooperate with each other. The first joint and the second joint can be directly snapped together, which makes it convenient for users to directly tie or quickly untie the cable using the fixing strap. The operation is simpler and the fixing strap will not be unusable or difficult to disassemble during use. It can prevent the cable on the dust-free cable chain from becoming loose and also reduce the overall cost of use.
[0017] 2. The outer and inner protective layers of the fixing strap in this utility model are made of ePTFE material, which meets the requirements for use in environments with high cleanliness levels and effectively improves the applicability of the fixing strap. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0028] See appendix Figures 1 to 8As shown in this embodiment, a dust-free cable chain anti-loosening fixing device includes a fixing strap 1. The two ends of the fixing strap 1 along its length are respectively provided with a first joint 2 and a second joint 3. The first joint 2 and the second joint 3 are detachably joined by a joint structure that cooperates with each other to bundle and cover the cable in the fixing strap 1. By setting the joint structure, it is convenient for users to directly tie or quickly untie the cable using the fixing strap 1, making the operation simpler. During use, there will be no phenomenon that the fixing strap 1 is not reusable or difficult to disassemble. It can prevent the cable on the dust-free cable chain from becoming loose and also reduce the overall usage cost.
[0029] Compared to the existing technology of using tape to wrap and fix cables on the same cleanroom cable chain, the detachable connection method of the fixing strap 1 can not only ensure that the cable is completely wrapped and covered in its circumference, improving the cable bundling efficiency, but also avoid the phenomenon that the sticky substances on the tape remain on the cable when the cable is untied, resulting in dust adhesion and the cable failing to meet the requirements for use in a cleanroom environment.
[0030] The securing strap 1 includes an outer protective layer 11 and an inner protective layer 13, both of which are made of ePTFE. After the cable is bundled and wrapped, the inner protective layer 13 of the securing strap 1 is in contact with the cable, while the outer protective layer 11 is in contact with the air in the cleanroom environment.
[0031] Among them, ePTFE material has high hydrophobicity, heat resistance, excellent chemical resistance, and insulation. The outer protective layer 11 and the inner protective layer 13 are made of ePTFE material. On the one hand, it enables the fixing strap 1 to have good dustproof and waterproof properties, meeting the requirements for use in environments with high cleanliness requirements, and effectively improving the applicability of the fixing strap 1. On the other hand, it will not corrode or break during long-term use, which can improve the service life of the fixing strap 1 and increase its reusability.
[0032] The length and width of the securing strap 1 are not limited and can be changed according to the number and diameter of the cables to be bundled. See the appendix for some embodiments. Figure 1 The width of the fixing strap 1 is set to 12cm.
[0033] The outer protective layer 11 and the inner protective layer 13 are connected and fixed by an adhesive layer 12. The adhesive layer 12 is elastic and forms a flexible fixing strap 1 after being bonded to the outer protective layer 11 and the inner protective layer 13 made of ePTFE material, so that the fixing strap 1 will not break during the process of bundling the cable.
[0034] In some embodiments, the adhesive layer 12 can be a double-sided adhesive film or a hot-pressed film, which is used to press the outer protective layer 11 and the inner protective layer 13 onto the adhesive layer 12 by adhesive bonding or hot pressing to form an integral fixing strap 1.
[0035] The first joint 2 has a plurality of female buckles 4, and the second joint 3 has a plurality of male buckles 5 that match the number and position of the female buckles 4. The female buckles 4 and the male buckles 5 can be elastically fastened to bundle and fix the cable.
[0036] The male buckle 5 includes a protruding locking post, and the female buckle 4 has a locking groove that matches the locking post, so that the user can quickly fix or remove the cable at both ends of the fixing strap 1.
[0037] In some embodiments, a plurality of female buckles 4 and male buckles 5 can be fixed to the fixing strap 1 by riveting or stamping.
[0038] The engaging ends of both the male buckle 5 and the female buckle 4 are located on the inner protective layer 13. See Appendix. Figure 5 After the cables are bundled, the first joint 2 and the second joint 3, which are interlocked, extend in a direction away from the cables.
[0039] One of the male buckle 5 and the female buckle 4 has its engaging end located on the inner protective layer 13, while the other has its engaging end located on the outer protective layer 11. See Appendix. Figures 1 to 4 The slot on the female buckle 4 is located on the inner protective layer 13, and the pin on the male buckle 5 protrudes from the outer protective layer 11. After the cable is bundled, compared with setting the snap-fit ends of the male buckle 5 and the female buckle 4 on the same side, the appearance is more beautiful and occupies less space while maintaining the same bundling stability.
[0040] Several of the aforementioned female clips 4 or male clips 5 are arranged in an array at intervals. The male clip 5 can be selected to press the position of the female clip 4 to accommodate the bundling and fixing of cables of different numbers or diameters.
[0041] In some embodiments, see Appendix Figure 1 Two male buckles 5 and two female buckles 4 are arranged side by side at intervals along the length of the fixing strap 1 to form a single row of buckle structure. Based on the remaining length at both ends of the fixing strap 1 after bundling the cable, the male buckle 5 is pressed into the matching female buckle 4.
[0042] Among them, the male buckle 5 and the female buckle 4 are respectively set at the two ends of the fixed strap 1 along its length.
[0043] In some embodiments, see Appendix Figure 3 There are four male buckles 5 and four female buckles 4, arranged in pairs in an array. The two ends of the fixing strap 1 are not easily separated under external force after being joined, which effectively improves the stability of cable bundling.
[0044] In some embodiments, see Appendix Figure 4 The male buckle 5 and female buckle 4 are arranged in three sets along the width direction of the fixing strap 1. Each set has two male buckles 5 and two female buckles 4 along the length direction of the fixing strap 1. The arrangement of multiple sets of male buckles 5 and female buckles 4 ensures the stability of cable bundling.
[0045] It should be noted that the number of male buckles 5 and female buckles 4 can be changed according to the width of the fixing strap 1 to accommodate different numbers and diameters of cables and prevent them from loosening. Both male buckles 5 and female buckles 4 are made of metal or plastic.
[0046] In some embodiments, the diameter of the groove on the female buckle 4 is 9mm, and the diameter of the post on the male buckle 5 is 7~8mm.
[0047] See appendix Figures 6 to 7 The first joint 2 has a D-ring buckle 6 or a D-ring pin buckle 7 as its connecting structure, while the second joint 3 has a connecting structure that secures the end of the strap 1. This belt-like buckle structure allows users to quickly bundle and secure cables on the cable chain, simplifying the operation and facilitating subsequent cable removal.
[0048] The end of the fixing strap 1 has several pin holes 8 that pass through it and match the pins on the D-ring buckle 7. This ensures that the cable is securely bound and the fixing strap 1 will not easily loosen, thus guaranteeing the stability of the cable binding.
[0049] In some embodiments, six pin buckle holes are provided, allowing for adjustable tightness when securing cables with the cable ties. Depending on the number and diameter of cables, after securing with the cable ties, the pins on the D-ring 7 are engaged into the corresponding pin buckle holes 8.
[0050] It should be noted that the joining structures in the above embodiments can all meet the requirements of a dust-free environment and can effectively avoid the risk of dust sticking to the joint structure caused by adhesive or Velcro.
[0051] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
