Description

Technical Field

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

[0002] In industrial automation, precision machinery, and cleanroom environments such as semiconductor manufacturing, food processing, and pharmaceutical production, cable chains are crucial components that protect cables, oil pipes, and other pipelines and guide their movement with equipment. The performance of their keel structure directly affects the overall operational stability and service life of the equipment. Currently, most cable chain keels on the market are made of plastic, which, while offering advantages in lightweight design and lower manufacturing costs, has gradually revealed many shortcomings in practical applications.

[0003] Existing cable chain keels are mostly made of plastic, which offers advantages in terms of lightweight and low cost. However, their suitability for industrial automation, precision machinery, and cleanroom environments has significant shortcomings. Plastic has limited strength and wear resistance, making it prone to deformation, collapse, or even breakage under long-stroke equipment movement or heavy-load conditions due to repeated bending and stress. This can lead to a loss of effective support for internal cables and oil pipes, potentially causing pipe entanglement and wear, as well as equipment malfunctions and disrupting production continuity. Furthermore, plastic generates fine debris and dust during continuous bending, which can directly contaminate products and the production environment in strictly cleanroom environments such as semiconductor manufacturing and pharmaceutical production, failing to meet cleanliness requirements. In addition, plastic has weak load-bearing capacity, making it unsuitable for heavy-load scenarios with multiple parallel pipelines. The splicing and fixing structures of existing plastic keels lack reliability, and joints are prone to loosening after prolonged use, compromising overall stability. While some single-metal keels meet strength standards, their excessive weight increases equipment load, or poor bending angle control can easily damage pipelines due to excessive bending. These issues make it impossible for existing cable chain keels to simultaneously achieve strength, wear resistance, dust-free operation, heavy-duty adaptability, and ease of installation, making it difficult to meet the stringent requirements of precision industrial scenarios. Therefore, it is essential to design a dust-free cable chain composite metal keel. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figures 1 to 4 The dust-free cable chain composite metal keel includes a metal strip 3, with a sleeve hole 31 on the surface of the metal strip 3, a keel mechanism 1 on the outside of the metal strip 3, and a fixing mechanism 2 inside the keel mechanism 1.

[0028] The keel mechanism 1 includes a support component 11, a limiting component 12 and a limiting component 2 13. The support component 11 is located on the outside of the metal strip 3 and on the inside of the metal strip 3. The limiting component 2 13 is located on the outside of the limiting component 12.

[0029] Support component 11 includes a support aluminum block 1101, which is disposed on the outside of the metal strip 3. The support aluminum block 1101 has bent oblique cut surfaces 1102 on the bottom of its left and right sides. Limiting component one 12 includes a lower cover 1201, which is sleeved on the metal strip 3 and the bottom of the outer side of the support aluminum block 1101. A retaining ring 1202 is fixedly connected to the top of the inner side of the lower cover 1201 and is engaged in the bottom of the support aluminum block 1101. A retaining protrusion 1203 is fixedly connected to the front and rear sides of the lower cover 1201. Limiting component two 13 includes an upper cover 1301, which is sleeved on the retaining ring 1202 and the top of the outer side of the support aluminum block 1101. A retaining hole 1302 is provided on the front and rear sides of the upper cover 1301 corresponding to the position of the retaining protrusion 1203. An installation groove 1303 is provided on the front and rear sides of the inner wall of the upper cover 1301 corresponding to the position of the retaining protrusion 1203.

[0030] Furthermore, compared to plastic solutions, this solution offers better wear resistance and support. The structure in this design uses composite materials, with the central support aluminum block 1101 made of aluminum, resulting in a lightweight structure. Since the function of the support aluminum block 1101 is to provide support, it enhances the overall load-bearing capacity of the keel, making it more suitable for long-stroke, heavy-duty dust-free cable chains.

[0031] The lower cover 1201 and the upper cover 1301 are made of stainless steel, which is harder than pure aluminum. The gap between the two sides of the lower cover 1201 and the upper cover 1301 can limit the bending radius of the keel.

[0032] Example 2

[0033] See Figures 1 to 4 Furthermore, based on Embodiment 1, the fixing mechanism 2 includes a fixing component 21 and a locking component 22. The fixing component 21 is snapped into the keel mechanism 1, and the locking component 22 is disposed on the outside of the fixing component 21.

[0034] The fixing component 21 includes a pin hole 2101, which is opened in the inner ring of the supporting aluminum block 1101. The pin hole 2101 is sleeved on the outer ring of the retaining ring 1202. A rivet 2102 is engaged in the inner ring of the pin hole 2101. The rivet 2102 is sleeved on the retaining ring 1202 and the inner ring of the sleeve hole 31. The rivet 2102 passes through the lower cover 1201, the metal strip 3 and the supporting aluminum block 1101. A stamping seat 2103 is fixedly connected to the bottom of the rivet 2102. The top of the stamping seat 2103 fits against the bottom of the lower cover 1201. The locking component 22 includes a tapered groove 2201, which is opened in the top of the supporting aluminum block 1101 at the position corresponding to the pin hole 2101. A stamped insert ring 2202 is engaged in the inner ring of the tapered groove 2201. The stamped insert ring 2202 is fixedly connected to the top of the rivet 2102.

[0035] Furthermore: After the rivet 2102 passes through the lower cover 1201 and the metal strip 3 and is engaged in the inner ring of the pin hole 2101, the upper and lower sides of the rivet 2102 are simultaneously pressed to form a stamping seat 2103 and a stamping insert ring 2202. At the same time, the stamping seat 2103 and the stamping insert ring 2202 cooperate to fix the rivet 2102 in the lower cover 1201, the metal strip 3, and the supporting aluminum block 1101, thus completing the splicing between the lower cover 1201, the supporting aluminum block 1101, and the metal strip 3. The process is simple and convenient for assembling the keel, and the operation is simple and convenient for workers to use.

[0036] In actual operation, when this device is used and the keel needs to be spliced, the worker places the metal strip 3 at the bottom of the lower cover 1201, and then places the supporting aluminum block 1101 on top of the metal strip 3, aligning the holes of the lower cover 1201, metal strip 3, and supporting aluminum block 1101 with the corresponding rivet 2102. Then, the rivet 2102 is inserted into the pin hole 2101, so that the rivet 2102 passes through the lower cover 1201, metal strip 3, and supporting aluminum block 1101, after which it can be used. The equipment stamps the rivet 2102. After the rivet 2102 is stamped, the excess part at the bottom forms a stamping seat 2103 that is stuck under the lower cover 1201. The part at the top that is located in the conical groove 2201 forms a stamping insert ring 2202 that is stuck in the conical groove 2201. At this time, the stamping seat 2103 and the stamping insert ring 2202 work together with the rivet 2102 to fix the lower cover 1201, the metal strip 3 and the supporting aluminum block 1101 until all the lower covers 1201 and the supporting aluminum blocks 1101 are installed.

[0037] Next, the workers place the top cover 1301 in the middle above the two bottom covers 1201, aligning the locking holes 1302 on the front and back sides of the top cover 1301 with the adjacent locking protrusions 1203 on the left and right sides of the bottom covers 1201. Then, the top cover 1301 is pressed downward, causing the locking protrusions 1203 on both sides to slide and lock into the inner ring of the locking holes 1302 through the installation grooves 1303. At this point, the installation of the top cover 1301 is completed. The above operation is repeated until all the top covers 1301 are installed, at which point the splicing production of the keel is completed.
