Description

Technical Field

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

[0002] Cleanroom cable chains are core transmission components designed specifically for high-cleanliness environments. They are widely used in precision manufacturing fields such as biomedicine, chip manufacturing, integrated circuits, and LCD manufacturing. Their core function is to protect the cables and pipes of electrical connection equipment, ensuring low dust accumulation, wear resistance, and stable signal transmission in cleanrooms, vacuum environments, and other scenarios. The long-stroke composite metal keel of the cleanroom cable chain serves as the internal support core of the cable chain. Its material and structure directly determine the service life, stroke, load capacity, and operational stability of the cable chain. If the keel performance is insufficient, it will directly lead to the failure of the cleanroom cable chain, thereby affecting the production efficiency of the entire automated production line.

[0003] Currently, the internal support keels of existing cleanroom cable chains on the market are mainly divided into two categories: plastic and metal. Although plastic keels are relatively inexpensive, they have poor wear resistance and weak load-bearing capacity. They are only suitable for low-end or short-stroke cleanroom cable chain products. After a period of use, they are prone to breakage and cannot meet the precision production needs of long stroke and high load. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a dust-free cable chain long-stroke composite metal keel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust-free cable chain metal long-stroke composite keel, including a base, a locking post fixedly connected to the outer side of the base, a limiting block fixedly connected to the top of the inner side of the base, a connecting belt provided at the bottom of the inner side of the base, an inner support frame slidably connected inside the base, a top cover provided at the top of the inner support frame, the top cover slidably connected to the outer periphery of the base, and a bridge fixedly connected to the top of the top cover.

[0006] Preferably, the bottom of the connecting strap is in contact with the bottom of the base, the top of the connecting strap is in contact with the bottom of the inner support frame, and the top of the inner side of the top cover is in contact with the top of the inner support frame. The connecting strap provides tension, making the device less prone to breakage.

[0007] Preferably, the upper cover has circular holes on the front and rear sides corresponding to the positions of the locking pins, and the locking pins are inserted into the inner side of the circular holes. Through the circular holes, the locking pins can be inserted into the front and rear sides of the upper cover, so that the upper cover can be installed on the outer side of the base.

[0008] Preferably, the top of the inner support frame has a slot corresponding to the position of the limiting block, and the limiting block is inserted into the slot. Through the slot, the limiting block can be inserted into the inner support frame, so that the inner support frame can be quickly installed into the base.

[0009] Compared with the prior art, this utility model provides a dust-free cable chain long-stroke composite metal keel, which has the following beneficial effects:

[0010] 1. This dust-free cable chain features a long-stroke metal composite keel. The base and inner support frame transmit tension via connecting straps. Precise insertion and positioning with limit blocks and slots ensure tight connections between components, significantly improving overall structural strength and effectively preventing breakage or loosening during long-stroke operation. This guarantees stable operation of the cable chain. The top cover quickly connects to the base's locking pins via circular holes, while the inner support frame precisely aligns with the limit blocks via slots. Assembly can be completed without complex tools, simplifying the installation process, shortening debugging time, and reducing labor costs. The inner support frame slides within the base, while the top cover slides against the base's outer perimeter. Reasonable clearances between components minimize sliding resistance, allowing for stable adaptation to long-stroke reciprocating motion scenarios. This ensures smooth, jam-free operation of the cable chain, reduces dust ingress, protects internal cables and pipes from contamination, is suitable for dust-free operating environments, and extends the service life of the cable chain and its internal components.

The connecting strap 5 provides tension, making the device less prone to breakage.

[0023] Furthermore, the front and rear sides of the top cover 1 are provided with circular holes corresponding to the positions of the locking pins 3, and the locking pins 3 are inserted into the inner side of the circular holes. Through the circular holes, the locking pins 3 can be inserted into the front and rear sides of the top cover 1, so that the top cover 1 can be installed on the outer periphery of the base 4.

[0024] Furthermore, the top of the inner support frame 2 is provided with a slot corresponding to the position of the limiting block 6, and the limiting block 6 is inserted into the slot. Through the slot, the limiting block 6 can be inserted into the inner support frame 2, so that the inner support frame 2 can be quickly installed into the base 4.

[0025] In actual operation, when this device is used, when it is necessary to install the device, place the connecting strap 5 inside the base 4 so that the bottom of the connecting strap 5 is in contact with the bottom of the inner side of the base 4, slide the inner support frame 2 into the base 4 so that the bottom of the inner support frame 2 is in contact with the top of the connecting strap 5, so that the limiting blocks 6 on the front and rear sides of the base 4 can be inserted into the inner side of the inner support frame 2, so that the inner support frame 2 can be quickly installed into the inner side of the base 4.

[0026] After the inner support frame 2 is installed, slide the upper cover 1 to the outside of the base 4 so that the top of the upper cover 1 can fit against the top of the inner support frame 2, so that the locking post 3 can be inserted into the upper cover 1, and the upper cover 1 can be quickly installed on the outside of the base 4. This makes it convenient for workers to install the cable chain quickly. The connecting belt 5 can provide tension so that the device is not easy to break during use.
