Description

Technical Field

[0001] The utility model relates to the technical field of rubber tubes, in particular to an anti-fracture rubber tube. Background Art

[0002] Rubber hose is a tube used to transport gas or liquid. Due to its high and low temperature resistance, high transparency, strong resilience, permanent compression resistance, oil resistance, and stamping resistance, it is widely used in various industrial and civil fields, such as liquid and gas transmission in mechanical equipment.

[0003] However, due to the soft texture of rubber tubes, they are easily worn, squeezed and stretched by external forces, especially at the connection between rubber tubes and external mechanical equipment. When they are pulled by external forces for a long time, they are more susceptible to wear and even breakage. Therefore, how to prevent rubber tubes from breaking during use has always been an urgent problem to be solved in the industry. Utility Model Content

[0006] Preferably, the outer wall of the rubber tube is sleeved with a tube sleeve, the inner wall of the tube sleeve is provided with a movable groove, and the inner side of the movable groove is provided with an arc-shaped clamping plate.

[0007] Preferably, a groove is formed on the outer wall of the pipe sleeve, and an adjusting bolt is threadedly connected to the inner wall of the pipe sleeve and located inside the groove, and one end of the adjusting bolt away from the groove is rotatably connected to the inner wall of the arc-shaped clamping plate.

[0008] Preferably, an anti-slip rubber pad is fixedly connected to the inner side wall of the arc-shaped clamping plate.

[0009] Preferably, a sealing ring 2 is fixedly connected to the inner wall of the pipe sleeve and to both the front and rear ends of the movable groove.

[0010] Compared with the related art, the anti-fracture rubber tube provided by the utility model has the following beneficial effects:

[0011] 1. The utility model provides an anti-fracture rubber tube. When the rubber tube needs to be connected to external equipment, the rotating ring sleeve drives the fixed ring to rotate, and the threaded ring is connected to the threaded port of the external equipment. The spring provides a buffering force between the fixed ring and the fixed sleeve, thereby preventing the rubber tube from being broken due to excessive tension.

[0012] 2. The utility model provides an anti-break rubber tube. When a leak occurs in the rubber tube body, the tube sleeve is slid to the leak location, and then the adjusting bolt is turned to tighten the inner wall of the arc-shaped clamping plate and the outer wall of the rubber tube to seal the leak location. The anti-slip rubber pad on the inner side of the arc-shaped clamping plate increases the friction between the clamping plate and the rubber tube when they are in contact, preventing the arc-shaped clamping plate from shifting in position when clamping the rubber tube, causing leakage of the medium.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: an anti-fracture rubber tube, comprising a rubber tube 1, a front end of the rubber tube 1 is fixedly connected with a fixing sleeve 2, a front end of the fixing sleeve 2 is provided with a connecting tube 8, the outer wall of the connecting tube 8 is slidably connected with the inner wall of the fixing sleeve 2, the outer wall of the connecting tube 8 is sleeved with a sealing ring 10, the sealing ring 10 is located inside the fixing sleeve 2, the outer wall of the fixing sleeve 2 is fixedly connected with a limiting ring 3, the outer side of the limiting ring 3 is sleeved with a ring sleeve 4, the front side wall of the ring sleeve 4 is fixedly connected with a protective tube 5, the inner wall of the protective tube 5 is fixedly connected with a telescopic rod 6, the end of the telescopic rod 6 away from the protective tube 5 is fixedly connected with a fixing ring 11, the inner wall of the protective tube 5 and located outside the telescopic rod 6 is fixedly connected with a spring 7, the end of the spring 7 away from the protective tube 5 is fixedly connected to the outer wall of the fixing ring 11, the outer wall of the fixing ring 11 away from the telescopic rod 6 is fixedly connected with a threaded ring 9, and the inner wall of the threaded ring 9 is fixedly connected to the outer wall of the connecting tube 8.

[0022] In this embodiment, the fixing sleeve 2 is designed with steel structure materials, and the steel structure has the characteristics of strong pressure resistance and bending resistance. When the fixing sleeve 2 is set on the front end of the rubber tube 1, the pressure resistance and bending resistance of the connecting end of the rubber tube 1 can be enhanced. The inside of the fixing sleeve 2 is sealed between the connecting pipe 8 and the fixing sleeve 2 through a sealing ring 10 to prevent the connecting pipe 8 from leaking the medium when it is pulled. When the rubber tube 1 needs to be connected to external equipment, the rotating ring sleeve 4 drives the fixing ring 11 to rotate, and the threaded ring 9 is connected to the threaded port of the external equipment. The spring 7 provides a buffering force between the fixing ring 11 and the fixing sleeve 2. When the rubber tube 1 is pulled, the connecting pipe 8 slides in the fixing sleeve 2, thereby preventing the rubber tube 1 from being broken due to excessive tension.

[0023] Embodiment 2:

[0024] See also Figure 1-Figure 5 As shown, on the basis of embodiment 1, the utility model provides a technical solution: the outer wall of the rubber tube 1 is sleeved with a sleeve 12, the inner wall of the sleeve 12 is provided with a movable groove, the inner side of the movable groove is provided with an arc-shaped clamping plate 15, the inner side wall of the arc-shaped clamping plate 15 is fixedly connected with a non-slip rubber pad 16, the outer wall of the sleeve 12 is provided with a groove 13, the inner wall of the sleeve 12 and the inner side of the groove 13 are threadedly connected with an adjusting bolt 14, the end of the adjusting bolt 14 away from the groove 13 is rotatably connected to the inner wall of the arc-shaped clamping plate 15, and the inner wall of the sleeve 12 and the front and rear ends of the movable groove are fixedly connected with a sealing ring 17.

[0025] In this embodiment, when a leak occurs in the rubber tube 1 body, the tube sleeve 12 is slid to the location of the leak, and then the adjusting bolt 14 is screwed to tighten the inner wall of the arc-shaped clamping plate 15 against the outer wall of the rubber tube 1 to seal the leak. The anti-slip rubber pad 16 on the inner side of the arc-shaped clamping plate 15 increases the friction between the clamping plate and the rubber tube 1 when they are in contact, preventing the arc-shaped clamping plate 15 from shifting in position when clamping the rubber tube 1, causing leakage of the medium. The sealing rings 17 at both ends of the tube sleeve 12 are brought closer to improve the sealing performance to prevent the medium from flowing out.

[0026] Working principle: The inside of the fixed sleeve 2 is sealed between the connecting pipe 8 and the fixed sleeve 2 through a sealing ring 10 to prevent the connecting pipe 8 from leaking the medium when it is pulled. When the rubber tube 1 needs to be connected to an external device, the rotating ring sleeve 4 drives the fixing ring 11 to rotate, and the threaded ring 9 is connected to the threaded port of the external device. The spring 7 provides a buffering force between the fixing ring 11 and the fixing sleeve 2, thereby preventing the rubber tube 1 from being broken due to excessive tension. When a leak occurs in the rubber tube 1 body, the sleeve 12 is slid to the position of the leak, and then the adjusting bolt 14 is turned to tighten the inner wall of the arc-shaped clamping plate 15 against the outer wall of the rubber tube 1 to seal the leak. The anti-slip rubber pad 16 on the inner side of the arc-shaped clamping plate 15 increases the friction when the clamping plate contacts the rubber tube 1, preventing the arc-shaped clamping plate 15 from shifting in position when clamping the rubber tube 1, causing leakage of the medium, and further improving the sealing performance by bringing the sealing rings 17 at both ends of the sleeve 12 closer to prevent the medium from flowing out.
