Description

TECHNICAL FIELD

[0001] The utility model relates to cable technical field especially relates to super low temperature ice cabinet twist resistant drag chain flexible cable. BACKGROUND

[0002] With the continuous development of modern refrigeration technology, super low temperature ice cabinet is more and more widely used in medical treatment, scientific research, food and other fields. In order to prevent the entanglement, wear, pull-off, suspension and disorder of cable, the cable is usually put into the cable drag chain to form protection, and the cable can also move back and forth with the drag chain. The existing patent (announcement number: CN218497806U) discloses a soft wear-resistant drag chain cable, which realizes the purpose of quick disassembly and arrangement, is more convenient to install and remove, and improves work efficiency. However, in actual application, since the diameters of different cables are different, if the diameter of the cable is too small, the cable is easy to move in the drag chain, which is easy to cause the loosening of the connecting part and is easy to make the connection between the cable and the electrical equipment unstable, which is not conducive to practical application. Therefore, we propose a super low temperature ice cabinet twist resistant drag chain flexible cable. SUMMARY

[0003] In order to solve the above problems, the utility model provides a super low temperature ice cabinet twist resistant drag chain flexible cable.

[0004] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0005] The super low temperature ice cabinet twist resistant drag chain flexible cable is designed, which comprises a drag chain and a cable body. The drag chain comprises a plurality of pairs of chain plates. Adjacent chain plates are connected through a rotating shaft. Fixed plates are arranged between the bottom parts of the opposite chain plates. A pressing plate is movably arranged above the fixed plates. An active support assembly is arranged on the fixed plate. The active support assembly comprises a mounting frame movably connected with the fixed plate. An elastic support roller vertically arranged in the mounting frame. The cable body comprises a sheath, a soft layer, a braided layer and a central cable core arranged from outside to inside. The sheath is a polyester-based nanometer conductive metal composite material layer.

[0006] In the above scheme, one end of the pressing plate is hinged with one side chain plate, and the other end of the pressing plate is detachably connected with the other side chain plate.

[0007] In the above scheme, a connecting plate is fixed on the other side chain plate. A clamping block is fixed on the connecting plate. A clamping groove matched with the clamping block is formed on the pressing plate.

[0008] In the above scheme, a moving port is formed in the side part of the fixed plate. A locking plate is fixed on the bottom part of the mounting frame. A screw rod inserted into the moving port is connected to the locking plate. The end part of the screw rod is locked with the fixed plate through a nut.

[0009] In the above scheme, the elastic support roller is located on one side of adjacent mounting frames that are close to each other.

[0010] In the above scheme, the surface of the elastic support roller is covered with high-elasticity sponge.

[0011] In the above scheme, the soft covering layer is a polytetrafluoroethylene raw material tape layer, and the braided layer is a metal-embedded graphene-polystyrene nanocomposite material layer.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a chain plate, pressure plate, fixed plate, and movable support assembly, the cable body is sequentially inserted between the pressure plate and the fixed plate, allowing the cable body to rely on the cable chain. The cable chain then moves the cable body in space, reducing wear on the cable body. By moving the mounting bracket left and right on the fixed plate, the elastic support roller is moved. Compared to existing technologies, adjusting the distance between adjacent elastic support rollers by moving them allows for adaptation to different cable body diameters, making it more flexible in use. By having the elastic support roller abut against the surface of the cable body, the cable body is limited, preventing frequent movement within the cable chain. Improving the installation stability of the cable body, thereby ensuring the connection stability between the cable body and the electrical equipment and power supply, and enhancing practicality, is achieved by setting a sheath. The sheath protects the inner structure of the cable body. Compared with existing technologies, the sheath is woven from a polyester-based nano-conductive metal composite material layer. This sheath not only has the characteristics of low-temperature resistance and non-brittleness, maintaining high strength and high flexibility, but also has very good wear resistance, able to withstand various frictions and pulls, and is not easily worn or torn. In addition, the combination with conductive metal fibers allows the static electricity generated during the friction between the sheath and the cable chain to be conducted to the outside, effectively avoiding the generation of a large amount of static electricity and improving the safety of the cable body in use.
