Description

Technical Field

[0001] The utility model specifically relates to the technical field of multi-core tubes, in particular to a multi-core tube structure capable of adjusting content space. Background Art

[0002] Hydraulic control technology is widely used in modern ships. A large number of valves are installed on ships, many of which are located in different cabins and cannot be controlled by manual operation. The ship valve remote control system can solve this problem well. In the ship valve remote control system, one end of the multi-core tube is connected to the valve remote control control unit, and the other end is connected to the remote control valve of each cabin, which plays the role of conveying hydraulic oil medium. The valve remote control control unit converts the power provided by the hydraulic power pump station into the pressure required for the system to work. The multi-core tube conveys hydraulic oil to transfer the pressure to each valve, driving the hydraulic power head to move.

[0003] In actual use, the conveying process of hydraulic oil inside the multi-core tube is mainly carried out by applying pressure through the power system. However, the laying of multi-core tubes is generally completed in a unified manner, and their size specifications are basically the same. When the internal material conveying capacity is small, in order to better convey the process, it is necessary to apply more pressure to the inside of the multi-core tube for stable conveying. For this reason, we have designed a multi-core tube structure that can adjust the content space. In this way, in actual use, you only need to change the internal content space to reduce the power output. Utility Model Content

[0004] The utility model aims to provide a multi-core tube structure capable of adjusting the content space, so as to solve the problems raised in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-core tube structure capable of adjusting the content space, comprising a tube body and connecting joints for mounting and fixing both ends of the tube body;

[0007] A plurality of wiring tubes are installed inside the tube body, and fillers are arranged between the wiring tubes and the tube body, and an air bag is arranged on the inner wall of the wiring tube;

[0008] The connection joint has a plurality of groups of conical interfaces integrally formed inside, and a gas nozzle is provided between the plurality of groups of conical interfaces.

[0009] As a further technical solution of the utility model, the airbag is fitted onto the inner wall of the wiring tube.

[0010] As a further technical solution of the utility model, the number of the wiring tubes is consistent with that of the conical interfaces, and the conical end of the conical interface is inserted into the interior of the wiring tube, and the airbag is located between the conical interface and the wiring tube.

[0011] As a further technical solution of the utility model, the tube body is sleeved on the outside of the connecting joint, and the tube body and the connecting joint are connected by glue.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, after the installation of the tube body and the connecting joint is completed, the conical interface will press the opening position of the airbag during the connection process, so that the airbag forms a separate space, and gas is injected into the interior of the airbag. At this time, the gas will enter the interior of the connecting joint. Since the density of the gas is smaller than that of the liquid, under the continuous inflation effect, the gas will enter the interior of the airbag along the gap between the airbag and the wiring tube, and inflate the airbag. After the airbag is inflated, it will expand and fill the space between the wiring tubes, thereby changing the content space inside the wiring tube and reducing the power output during transportation.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 In an embodiment of the utility model, a multi-core tube structure capable of adjusting the content space includes a tube body 1 and connecting joints 2 for mounting and fixing the two ends of the tube body 1;

[0022] A plurality of wiring tubes 10 are installed inside the tube body 1, and a filler 11 is arranged between the wiring tube 10 and the tube body 1, and an air bag 12 is arranged on the inner wall of the wiring tube 10;

[0023] The connection joint 2 has a plurality of groups of conical interfaces 20 integrally formed inside, and a gas nozzle 21 is provided between the plurality of groups of conical interfaces 20 .

[0024] In this embodiment, the airbag 12 is installed in close contact with the inner wall of the wiring tube 10 .

[0025] In this embodiment, the number of the wiring tubes 10 and the tapered interfaces 20 is the same, and the tapered end of the tapered interface 20 is inserted into the interior of the wiring tube 10 , and the airbag 12 is located between the tapered interface 20 and the wiring tube 10 .

[0026] In this embodiment, the tube body 1 is sleeved on the outside of the connecting joint 2, and the tube body 1 and the connecting joint 2 are connected by glue.

[0027] The working principle of the utility model is: when in use, a tube body 1 of appropriate length is cut for installation, and connecting joints 2 are installed at both ends of the laid tube body 1. After the two are installed, the conical interface 20 will press the opening position of the airbag 12 during the connection process, so that the airbag 12 at this time forms a separate space. When it is necessary to adjust the content space of the wiring tube 10 inside the tube body 1, it is only necessary to open the air nozzle 21 at the connecting joint 2 at one end of the tube body 1 and inject gas into it. At this time, the gas will enter the interior of the connecting joint 2. Since the density of the gas is less than that of the liquid, under the continuous inflation effect, the gas will enter the interior of the airbag 12 along the gap between the airbag 12 and the wiring tube 10, and inflate the airbag 12. After the airbag 12 is inflated, it will expand and fill the space between the wiring tubes 10, thereby changing the content space inside the wiring tube 10 and reducing the power output during transportation.
