[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The existing high-seal rubber hoses require external tools to rotate multiple nuts and screw them onto bolts during installation, which makes the installation process cumbersome and reduces the efficiency of installing existing high-seal rubber hoses.

[0023] In view of this, the present invention provides an oil-resistant and heat-resistant high-sealing rubber hose, which solves the problem of installing two high-sealing rubber hoses without the need for external tools by using the cooperation of studs, threaded sleeves, knobs, connecting blocks, rotating shafts and columns. This solves the problem that in the existing high-sealing rubber hose installation, multiple nuts need to be turned with external tools to rotate the nuts onto bolts to complete the installation of two high-sealing rubber hoses, which is relatively difficult and requires the use of external tools, thus reducing the installation efficiency of the existing high-sealing rubber hose.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] Example 1: By Figure 1-5 It is known that an oil-resistant and heat-resistant high-sealing rubber hose includes a hose body 1, with joints 2 fixedly connected to both ends of the hose body 1. The oil-resistant and heat-resistant high-sealing rubber hose also includes an installation mechanism 3, a fixing mechanism 4, and an auxiliary mechanism 5. The installation mechanism 3 is located outside the joints 2. When two high-sealing rubber hoses are installed, the joints 2 of the two high-sealing rubber hoses are brought together. The installation mechanism 3 quickly installs the two high-sealing rubber hoses together without the need for external tools. The fixing mechanism 4 is located at the bottom of the installation mechanism 3. When the installation mechanism 3 is not in use, the fixing mechanism 4 fixes the unused installation mechanism 3 to prevent it from shaking and colliding with the joints 2. The auxiliary mechanism 5 is located outside the joints 2. The installation mechanism 3 enables the rapid installation of two high-sealing rubber hoses, the fixing mechanism 4 fixes the unused installation mechanism 3, and the auxiliary mechanism 5 improves the overall performance of the high-sealing rubber hose.

[0026] In the specific implementation process, it is worth noting that when two high-seal rubber tubes are installed, the joints 2 of the two high-seal rubber tubes are put together, and the two high-seal rubber tubes are quickly installed together through the installation mechanism 3 without the need for external tools. If the installation mechanism 3 is not in use, the unused installation mechanism 3 is fixed by the fixing mechanism 4 to prevent the installation mechanism 3 from shaking and colliding with the joints 2.

[0027] Specifically, when installing two high-seal rubber tubes, the joints 2 of the two high-seal rubber tubes are attached together, and the two high-seal rubber tubes are quickly installed together through the installation mechanism 3 without the need for external tools. If the installation mechanism 3 is not in use, the fixing mechanism 4 is used to fix the unused installation mechanism 3 to prevent the installation mechanism 3 from shaking and colliding with the joints 2.

[0028] Example 2: From Figure 1-5It is known that the installation mechanism 3 includes studs 31, threaded sleeves 32, knobs 33, connecting blocks 34, rotating shafts 35, and columns 36. When installing two high-seal rubber tubes, the operator first moves the two high-seal rubber tubes so that the joints 2 of the two high-seal rubber tubes are close together. Then, the operator moves and rotates the studs 31 on the two high-seal rubber tubes. The end of the column 36 is fixedly connected to the outer wall of the joint 2. The rotating shaft 35 is rotatably connected to the inner wall of the column 36 through a bearing. The connecting block 34 is fixedly connected to the outer wall of the rotating shaft 35. The connecting block 34 drives the rotating shaft 35 to rotate, causing the studs 31 to rotate 180 degrees, bringing the studs 31 on both sides closer together. The studs 31 are fixedly connected to one side of the connecting block 34. The studs 31 drive the connecting block 34 to rotate, and the threaded sleeve 32 screws in... The threaded sleeve 32 is fixedly connected to the outer wall of the stud 31; the knob 33 is fixedly connected to the outer wall of the threaded sleeve 32; the operator rotates the knob 33, which drives the threaded sleeve 32 to rotate, and the threaded sleeve 32 moves on the stud 31. When the threaded sleeve 32 contacts the two studs 31, the operator stops rotating the knob 33. At this time, the two high-seal rubber tubes are connected together. When the installation is removed, the operator rotates the knob 33 in the opposite direction, so that the threaded sleeve 32 moves back to the initial stud 31, and the installation of the two high-seal rubber tubes is removed. The connecting block 34 rotates 180 degrees around the rotating shaft 35 under the drive of the stud 31. Then, the threaded sleeve 32 moves along the stud 31 under the drive of the knob 33, and rotates the threaded sleeve 32 into the two adjacent studs 31 for installation.

[0029] In the specific implementation process, it is worth noting that when installing two high-seal rubber tubes, the worker first moves the two high-seal rubber tubes so that the joints 2 of the two high-seal rubber tubes are close to each other and fit together. Then, the worker moves and rotates the studs 31 on the two high-seal rubber tubes. The studs 31 drive the connecting block 34 to rotate, and the connecting block 34 drives the rotating shaft 35 to rotate, so that the studs 31 rotate 180 degrees and bring the studs 31 on both sides closer together. After that, the worker rotates the knob 33, which drives the threaded sleeve 32 to rotate. The threaded sleeve 32 moves on the studs 31. When the threaded sleeve 32 contacts the two studs 31, the worker stops rotating the knob 33. At this time, the two high-seal rubber tubes are connected together. When the installation is removed, the worker rotates the knob 33 in the opposite direction, so that the threaded sleeve 32 moves back to the initial stud 31, thus removing the installation of the two high-seal rubber tubes. This achieves the installation of the two high-seal rubber tubes without the use of external tools.

[0030] Furthermore, the fixing mechanism 4 includes a horizontal column 41, a plug rod 42, a socket 43, a vertical column 44, a spring 45, and a sleeve 46. The socket 43 is located at the bottom of the connecting block 34; the plug rod 42 is inserted into the inner wall of the socket 43; the horizontal column 41 is fixedly connected to the end of the plug rod 42; the horizontal column 41 drives the plug rod 42 to descend. At this time, the operator rotates the stud 31 back to its initial state. After completion, the operator releases the horizontal column 41. At this time, the spring 45 rebounds, and the spring force inserts the plug rod 42 into the socket 43, fixing the unused installation mechanism 3. When the operator needs to use the installation mechanism 3, the operator presses down the horizontal column 41 again, causing the plug rod 42 to be inserted into the socket 43. 2. After leaving the socket 43, release the fixing of the installation mechanism 3. The vertical column 44 is fixedly connected to the side of the horizontal column 41 away from the insertion rod 42. The sleeve 46 is sleeved on the outer wall of the vertical column 44. When the installation mechanism 3 is not in use, the operator presses down on the horizontal column 41. The horizontal column 41 drives the vertical column 44 to move in the sleeve 46. Both ends of the spring 45 are fixedly connected to the end of the vertical column 44 and the inner wall of the sleeve 46. The vertical column 44 compresses the spring 45. Under the drive of the horizontal column 41, the vertical column 44 compresses the spring 45, thereby causing the insertion rod 42 to descend. After aligning the insertion rod 42 with the socket 43, release the horizontal column 41. The spring 45 rebounds and inserts the insertion rod 42 into the socket 43.

[0031] In the specific implementation process, it is worth noting that when the installation mechanism 3 is not in use, the staff presses down on the horizontal column 41, which drives the vertical column 44 to move in the sleeve 46. The vertical column 44 compresses the spring 45, and the horizontal column 41 drives the insertion rod 42 to descend. At this time, the staff rotates the stud 31 back to its initial state. After that, the staff releases the horizontal column 41. At this time, the spring 45 rebounds and inserts the insertion rod 42 into the insertion hole 43 through the elastic force, thus fixing the unused installation mechanism 3. When the staff needs to use the installation mechanism 3, the staff presses down on the horizontal column 41 again to make the insertion rod 42 leave the insertion hole 43, thereby releasing the fixing of the installation mechanism 3 and ensuring that the installation mechanism 3 is in a stable state when idle.

[0032] Furthermore, the pipe body 1 includes an outer layer 11, a heat-resistant layer 12, and an oil-resistant layer 13. The outer wall of the outer layer 11 is fixed to the inner walls of the two connectors 2 on both sides. The outer layer 11 is made of neoprene rubber, which has good weather resistance, ozone resistance, and chemical corrosion resistance, as well as high mechanical strength, providing the rubber hose with certain wear resistance and anti-aging properties. The heat-resistant layer 12 is fixedly connected to the inner wall of the outer layer 11. The heat-resistant layer 12 is made of polytetrafluoroethylene (PTFE), which has very high heat resistance, can work stably at high temperatures for extended periods, and has an extremely low coefficient of friction and good chemical stability, effectively blocking heat transfer and protecting the rubber hose. Other parts of the hose are not affected by high temperature. The oil-resistant layer 13 is fixedly connected to the inner wall of the heat-resistant layer 12. The material of the oil-resistant layer 13 is nitrile rubber. Nitrile rubber has good resistance to petroleum-based oils, animal and vegetable oils, etc. By adjusting the acrylonitrile content, different oil resistance requirements can be met. In the manufacturing process of the rubber hose, the rubber materials of the outer layer 11, heat-resistant layer 12 and oil-resistant layer 13 are vulcanized under specific temperature, pressure and time conditions, so that the rubber molecular chains of each layer are chemically bonded together, thereby achieving a firm connection. Among them, the oil and heat resistance of the high-sealing rubber hose is improved by the heat-resistant layer 12 and the oil-resistant layer 13.

[0033] In the specific implementation process, it is worth noting that the outer layer 11 is made of chloroprene rubber, which has good weather resistance, ozone resistance, and chemical corrosion resistance, as well as high mechanical strength, providing the rubber hose with certain wear resistance and anti-aging properties. The heat-resistant layer 12 is made of polytetrafluoroethylene (PTFE), which has very high heat resistance, can work stably at high temperatures for a long time, and has an extremely low coefficient of friction and good chemical stability, effectively blocking heat transfer and protecting other parts of the rubber hose from high temperature. The oil-resistant layer 13 is made of nitrile rubber, which has good resistance to petroleum-based oils, animal and vegetable oils, etc. By adjusting the acrylonitrile content, different oil resistance requirements can be met. During the manufacturing process of the rubber hose, the rubber materials of the outer layer 11, heat-resistant layer 12, and oil-resistant layer 13 are vulcanized under specific temperature, pressure, and time conditions, so that chemical bonds are formed between the rubber molecular chains of each layer, thereby achieving a strong connection and realizing the heat and oil resistance of the high-sealing rubber hose.

[0034] Furthermore, the auxiliary mechanism 5 includes a positioning ring 51, a positioning groove 52, and a sealing assembly 53. The positioning ring 51 is fixedly connected to the outer wall of one connector 2; the positioning groove 52 is formed on the surface of the other connector 2; when the two connectors 2 that are close to each other are put together, one connector 2 drives the positioning ring 51 to move, inserting the positioning ring 51 into the positioning groove 52 inside the other connector 2; the sealing assembly 53 is disposed on the end face of the connector 2; wherein, the positioning ring 51 and the positioning groove 52 are used to position the two contacting connectors 2.

[0035] In the specific implementation process, it is worth noting that when the two close-to-each joints 2 are put together, one of the joints 2 drives the positioning ring 51 to move and insert the positioning ring 51 into the positioning groove 52 inside the other joint 2, thereby positioning the two high-sealing rubber tubes.

[0036] Furthermore, the sealing assembly 53 includes a sealing ring 531, a placement groove 532, and a convex ring 533. The placement groove 532 is formed on the side of the connector 2 near the positioning groove 52. The sealing ring 531 is placed on the inner wall of the placement groove 532. The operator places the sealing ring 531 into the placement groove 532, and the convex ring 533 is fixedly connected to the side of the connector 2 near the positioning ring 51. When the two connectors 2 are fitted together, one connector 2 drives the convex ring 533 to move, inserting the convex ring 533 into the placement groove 532 inside the other connector 2. At the same time, the convex ring 533 squeezes the sealing ring 531 inside the placement groove 532. Specifically, the sealing ring 531 is placed into the placement groove 532, and finally the convex ring 533 squeezes the sealing ring 531.

[0037] In the specific implementation process, it is worth noting that when the staff puts the sealing ring 531 into the placement groove 532, when the two connectors 2 are put together, one connector 2 drives the convex ring 533 to move, inserting the convex ring 533 into the placement groove 532 inside the other connector 2. At the same time, the convex ring 533 squeezes the sealing ring 531 inside the placement groove 532 to improve the sealing between the two connectors 2.

[0038] Specifically, when installing two high-seal rubber tubes, the operator first moves the two tubes so that their joints 2 are close together. At this point, one joint 2 moves the positioning ring 51, inserting it into the positioning groove 52 inside the other joint 2. Simultaneously, one joint 2 moves the convex ring 533, inserting it into the placement groove 532 inside the other joint 2. The convex ring 533 also presses against the sealing ring 531 inside the placement groove 532. After this, the operator moves and rotates the studs 31 on the two high-seal rubber tubes. The studs 31 rotate the connecting block 34, connecting... The connecting block 34 drives the rotating shaft 35 to rotate, causing the stud 31 to rotate 180 degrees, bringing the studs 31 on both sides closer together. After completion, the operator rotates the knob 33, which drives the threaded sleeve 32 to rotate. The threaded sleeve 32 moves on the studs 31. When the threaded sleeve 32 contacts the two studs 31, the operator stops rotating the knob 33. At this time, the two high-seal rubber tubes are connected together. To disassemble, the operator rotates the knob 33 in the opposite direction, causing the threaded sleeve 32 to move back to the initial stud 31, thus disassembling the two high-seal rubber tubes. When the installation mechanism 3 is not in use, the operator presses down on the horizontal column 41, which drives the vertical column 44 to... As the sleeve 46 moves, the vertical column 44 compresses the spring 45, and the horizontal column 41 drives the insertion rod 42 to descend. At this time, the operator rotates the stud 31 back to its initial state. After completion, the operator releases the horizontal column 41, and the spring 45 rebounds, using its elasticity to insert the insertion rod 42 into the insertion hole 43, thus fixing the unused installation mechanism 3. When the operator needs to use the installation mechanism 3, the operator presses down the horizontal column 41 again, causing the insertion rod 42 to leave the insertion hole 43, releasing the fixing of the installation mechanism 3. Meanwhile, the outer layer 11 is made of neoprene rubber, which has good weather resistance, ozone resistance, and chemical corrosion resistance, and high mechanical strength, and can provide... The rubber hose provides certain wear resistance and anti-aging properties. The heat-resistant layer 12 is made of polytetrafluoroethylene (PTFE), which has very high heat insulation properties. It provides some protection for the outer layer 11, which has slightly weaker heat resistance than the oil-resistant layer 13. It has an extremely low coefficient of friction and good chemical stability, which can effectively block heat transfer and protect other parts of the rubber hose from high temperatures. The oil-resistant layer 13 is made of nitrile rubber, which has good resistance to petroleum-based oils, animal and vegetable oils, etc. By adjusting the acrylonitrile content, different oil resistance requirements can be met, and it can work for a long time at 100-120 degrees Celsius, improving the heat and oil resistance of the high-sealing rubber hose.
