Description

Technical Field

[0001] This utility model relates to the field of flexible cable chains, specifically to a waterproof network cable for flexible cable chains. Background Technology

[0002] Drag chain cables are highly flexible, specialized cables that can reciprocate alongside moving devices without easily wearing out. They are also commonly known as drag cables or tank chain cables. Drag chain cables mainly consist of a drag chain and a cable. The drag chain protects the internal cable, restricts its movement, and prevents the cable from becoming tangled and disorganized during movement due to lack of support. The drag chain resembles a tank track and is composed of numerous interconnected units that can rotate freely. There are three types of semi-enclosed drag chain cables, and their applications are wide-ranging, including industrial electronic systems, automated production lines, warehousing equipment, robots, fire protection systems, cranes, CNC machine tools, and the metallurgical industry. Generally, due to the structure of drag chain cables, after the cable is stored, it is easy for it to be exposed to [unspecified material].

[0003] In direct contact with the external environment, the air inside the factory becomes humid during rainy weather or when there is a large temperature difference between indoors and outdoors. This can easily cause water mist, which can damage the cables inside the cable chain after prolonged contact. This significantly reduces the lifespan of the cables, affects their normal use, reduces their working efficiency, and causes economic losses. Utility Model Content

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0021] In this embodiment, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0022] Furthermore, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.

[0023] This utility model provides a flexible drag chain waterproof network cable, such as Figure 1-6 As shown, it includes a first chain plate 1, a second chain plate 2, a first cover plate 3, a second cover plate 4, a hinge end 5, and a connecting cover plate 6. The first chain plate 1 and the second chain plate 2 are arranged in parallel. The first cover plate 3 and the second cover plate 4 are fixedly installed between the first chain plate 1 and the second chain plate 2. The first chain plate 1 is located above the second cover plate 4. Both ends of the first chain plate 1 and the second chain plate 2 are provided with the hinge end 5. Several first chain plates 1 and second chain plates 2 are arranged in an array and are hinged through the hinge end 5. Waterproof grooves 31 are opened on the sides of the first cover plate 3 and the second cover plate 4. The connecting cover plate 6 is arranged between two adjacent first cover plates 3. Plate 6 includes an elastic hinge shaft 61 and baffles 62 disposed on the movable ends of the elastic hinge shaft 61 on both sides. The baffles 62 extend toward the waterproof groove 31 and enter the interior of the waterproof groove 31. The elastic hinge shaft 61 has a built-in return spring 63, which drives the baffles 62 to rotate toward the inside of the cable chain. The return spring 63 in the elastic hinge shaft 61 drives the baffles 62 to move toward the inside of the cable chain from both sides. The baffles 62 abut against the inside of the waterproof groove 31, thereby improving the prevention of water vapor and mist from entering the inside of the cable chain. When the cable chain rotates, the elastic hinge shaft 61 rotates with the cable chain, and the baffles 62 are always located inside the waterproof groove 31, thereby maintaining the waterproof effect.

[0024] Preferably, a rubber seal 32 is provided between the baffle 62 and the waterproof groove 31. The baffle 62 is driven to rotate toward the rubber seal 32 by the reset spring 63 built into the elastic hinge shaft 61, so that the baffle 62 always has pressure on the rubber seal 32, thereby maintaining the waterproof effect.

[0025] Preferably, a waterproof membrane 64 is applied to the elastic hinge shaft 61 to improve the sealing performance of the elastic hinge shaft 61.

[0026] Preferably, a plurality of buffer springs 33 are installed on the inner side of the first cover plate 3 and the second cover plate 4. The end of the buffer spring 33 is fixedly connected to a pressure plate 34. The pressure plate 34 abuts against the network wire to prevent the network wire from directly contacting the first chain plate 11 and the first cover plate 3, so that the drag chain will not pull the network wire when rotating.

[0027] Preferably, the first cover plate 3 is provided with a sliding groove 35 inside, and the buffer spring 33 is fixed to the movable part on the sliding groove 35, so as to reduce the pressure on both sides of the network cable when the cable chain rotates.

[0028] Preferably, after the adjacent first chain plates 11 are hinged together by the hinge end 5, they enter the limiting groove 52 through the limiting block 51 to avoid the drag chain bending excessively and squeezing the network line.

[0029] Preferably, the inner side of the waterproof groove 31 is provided with a rubber waterproof layer 36 to further improve waterproofing.

[0030] The main technical effects of this utility model are as follows: the return spring inside the elastic hinge shaft drives the baffle from both sides toward the inside of the cable chain, and the baffle abuts against the inside of the waterproof groove, thereby improving the prevention of water vapor and water mist from entering the inside of the cable chain; and when the cable chain rotates, the elastic hinge shaft rotates with the cable chain, and the baffle is always located inside the waterproof groove, thereby maintaining the waterproof effect.

[0031] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
