[0038] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0039] Please refer to Figure 1 and Figure 2 A composite hose assembly according to an embodiment of the present invention includes: a hose 1, a connector 2, and an anti-bend sheath 3.
[0040] The connector 2 includes a tail tube 21212 and a fixing sleeve 22. The fixing sleeve 22 is arranged around the outside of the tail tube 21212 and is fixedly connected to the tail tube 21212. A slot 23 is formed between the fixing sleeve 22 and the outer peripheral surface of the tail tube 21212. One end of the hose 1 is inserted into the slot 23 through the other end of the fixing sleeve 22. The inside of the tail tube 21212 is connected to the inside of the hose 1.
[0041] The anti-bend sleeve 3 includes a first section 31 and a second section 32 connected to each other along its own axis. The first section 31 is sleeved on the hose 1, and the second section 32 is sleeved on the fixing sleeve 22. Alternatively, the second section 32 is sleeved on one end of the hose 1 connecting joint 2 and inserted into the slot 23.
[0042] In this embodiment of the invention, the anti-bending sleeve 3 partially acts on the hose 1, and partially interacts with the fixing sleeve 22. Whether the anti-bending sleeve 3 and the hose 1 are inserted into the slot 23 together, or a portion of the anti-bending sleeve 3 is fitted onto the fixing sleeve 22, the anti-bending sleeve 3 can wrap around the part that is frequently pulled or bent, improving the torsional resistance of the composite hose 1. This can effectively reduce the occurrence of problems such as easy breakage and leakage of the composite hose 1, prevent hazardous chemicals or gases from leaking into the atmosphere and causing pollution, and effectively prevent the occurrence of safety accidents.
[0043] The fixing sleeve 22 is a steel sleeve. In this embodiment, one end of the fixing sleeve 22 is connected to the tail tube 21212, and the other end of the fixing sleeve 22 is used to form an opening. The end of the hose 1 enters the slot 23 through the opening to realize the connection between the hose 1 and the tail tube 21212.
[0044] Please refer to Figure 4 The composite hose 1 assembly also includes a second seal 4, which is disposed within the slot 23. The second seal 4 is used to seal the gap between the hose 1 and the tail tube 21212. The second seal 4 can seal the gap between the hose 1 and the tail tube 21212, and also seal the slot 23 to prevent liquid from leaking from the slot 23.
[0045] In this embodiment, the flexible hose 1 includes an inner metal skeleton 11, an outer metal skeleton 12, a barrier layer 13, a reinforcing layer 14, and an outer sheath 15. The barrier layer 13, the reinforcing layer 14, and the outer sheath are composed of multiple layers of functional polymer film and synthetic fiber fabric reinforcing layer 14, forming the hose body of the flexible hose 1. Spiral grooves are formed on both the inner and outer walls of the hose body. The inner metal skeleton 11 is disposed in the spiral groove on the inner wall of the hose body, and the outer metal skeleton 12 is disposed in the spiral groove on the outer wall of the hose body. Both the inner metal skeleton 11 and the outer metal skeleton 12 are spiral metal wires.
[0046] In some embodiments, the connector 2 further includes a main tube 24, which is connected to the end of the tail tube 21212 away from the hose 1. The main tube 24 and the tail tube 21212 are connected. A through hole 241 is provided on the wall of the main tube 24, and a sight glass 25 is provided at the through hole 241.
[0047] By setting up a viewing mirror 25, the work process can be visualized and monitored, which helps to improve operational safety and avoid potential safety hazards.
[0048] In this embodiment, the material of the viewing mirror 25 includes glass.
[0049] The end of the main tube 24 that faces away from the tail tube 21212 can be set according to the actual situation. Figure 2 male connector 2 or Figure 5 2. Female connector.
[0050] Please refer to Figure 3 The connector 2 also includes a shockproof seal 26 disposed on the edge of the sight glass 25, and the sight glass 25 is installed at the through hole 241 through the shockproof seal 26.
[0051] The sight glass 25 is indirectly in contact with the main tube 24 through the anti-vibration seal 26, so that the vibration of the composite hose 1 assembly will not be transmitted to the sight glass 25, thereby protecting the sight glass 25. In this embodiment, the anti-vibration seal 26 can also seal the gap between the sight glass 25 and the main tube 24, preventing the liquid inside the main tube 24 from flowing out through the through hole 241.
[0052] A groove is provided on the inner wall of the main tube 24, and a part of the shockproof seal 26 is inserted into the groove. In addition, a step is provided on the inner wall of the main tube 24, and the shockproof seal 26 on the side of the sight glass 25 away from the hose 1 is also abutted on the step, limiting the position of the shockproof seal 26.
[0053] The sight glass 25 is located inside the main tube 24, and the shockproof seal 26 is set on the inner wall of the main tube 24. The sight glass 25 is annular and covers the through hole 241.
[0054] With this structure, there is a certain distance between the outer peripheral surface of the main tube 24 and the sight glass 25. When the main tube 24 comes into contact with external objects, this distance can reduce the possibility of external objects coming into contact with the sight glass 25, thereby protecting the sight glass 25.
[0055] A collision protection part 27 protruding from the outer circumference of the main tube 24 is provided on the outer circumference of the main tube 24, and the collision protection part 27 is arranged around the outer circumference of the main tube 24.
[0056] The anti-collision part 27 can be made of industrial plastic, which has a certain elasticity and strength. When the connector 2 is hit by an external impact, the anti-collision part 27 can first contact the impacting object, so that the sight glass 25 can be in an anti-collision and shock-absorbing state, protecting the sight glass 25 and extending the service life of the sight glass 25.
[0057] The main tube 24 and the tail tube 21212 are integrally formed. Alternatively, the main tube 24 and the tail tube 21212 are separate parts.
[0058] In this embodiment, the main tube 24 is provided with internal threads, and the tail tube 21212 is provided with external threads, and the two are connected by threads. Alternatively, the two can be connected by flanges.
[0059] A first sealing element 28 is provided between the inner wall of the main tube 24 and the opening of the tail tube 21212. The first sealing element 28 is used to seal the gap between the main tube 24 and the tail tube 21212.
[0060] In the case of a separate configuration, the sealing between the main tube 24 and the tail tube 21212 needs to be considered. A first sealing element 28 is installed to seal the gap between the main tube 24 and the tail tube 21212, thereby preventing liquid from leaking from the connection between the main tube 24 and the tail tube 21212.
[0061] The first sealing element 28 can be a sealing gasket or a sealing filler.
[0062] The connector 2 also includes a clamping head 29, which is disposed on the inner wall of the main tube 24. The clamping head 29 presses against the anti-vibration seal 26 on one side of the sight glass 25, causing the anti-vibration seal 26 on the other side of the sight glass 25 to press against the inner wall of the main tube 24.
[0063] The clamping head 29 is set up so that the sight glass 25 and the shockproof seal 26 abut against the inner wall of the main tube 24, which serves to fix the position of the sight glass 25.
[0064] When the end of the tailpipe 21212 enters the main tube 24, the first seal 28 is squeezed to achieve a seal. At the same time, the pressing head 29 is subjected to force and pressed against the anti-vibration seal 26 on the side of the sight glass 25 facing the tailpipe 21212, pressing the anti-vibration seal 26 and the sight glass 25 against the inner wall of the main tube 24 to fix the position of the sight glass 25.
[0065] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
