[0001] This utility model relates to the field of rubber hose technology, specifically to a rubber hose for oil transportation and transfer. Background Technology

[0002] Rubber hoses used in oil transportation and transshipment are among the key pieces of equipment, primarily used for the safe and efficient transport of crude oil, refined oil, or other petroleum products in different stages and scenarios. These rubber hoses need to possess multiple properties such as oil resistance, pressure resistance, corrosion resistance, and durability to cope with complex operating conditions.

[0003] However, existing rubber hoses still have the following technical problems in use:

[0004] Existing oil pipelines are connected and fixed by multiple sections of rubber hoses during use. The current fixing method mainly relies on the use of flanges and bolts, which makes the connection and fixing difficult. After long-term use, if the bolts and flanges become stuck due to rust, it is difficult to disassemble and replace the rubber hoses.

[0005] Therefore, a rubber hose for oil transportation and transfer is proposed to solve the problems mentioned above. Summary of the Invention

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.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", 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 this utility model and simplifying the description, and do not 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 this utility model.

[0022] Example:

[0023] Please refer to Figures 1-4. This utility model provides a technical solution:

[0024] A rubber hose for transporting and transferring oil includes a first hose body 1 and a second hose body 2. A fixing pipe 3 is provided between the first hose body 1 and the second hose body 2. An insert pipe 4 is fixed to the side wall of the fixing pipe 3. The left and right ends of the insert pipe 4 extend into the interior of the first hose body 1 and the second hose body 2. Rubber sealing plugs 5 are fixed to the left and right ends of the outer wall of the insert pipe 4. The rubber sealing plugs 5 are squeezed more as the first hose body 1 and the second hose body 2 get closer, resulting in a better sealing effect. The two rubber sealing plugs 5 are respectively engaged with the openings of the first hose body 1 and the second hose body 2. Annular clamping plates 6 are fixed to the outside of the first hose body 1 and the second hose body 2. Mounting blocks 7 are fixed to the upper and lower sides of the fixing pipe 3. Adjustment mechanisms are provided inside the two mounting blocks 7. The upper and lower ends of the two annular clamping plates 6 on opposite sides are provided with slots. The two ends of the mounting blocks 7 are fixed with clamping blocks 8 through the adjustment mechanisms, and the clamping blocks 8 are engaged with the slots.

[0025] The first hose body 1 and the second hose body 2 include a wear-resistant layer 9, an inner tube 10 is provided outside the wear-resistant layer 9, a steel wire reinforcing layer 11 is provided outside the inner tube 10, and an outer tube 12 is provided outside the steel wire reinforcing layer 11.

[0026] The two rubber sealing plugs 5 are frustoconical in shape. The cross-section of one end of the two rubber sealing plugs 5 extending into the first rubber tube body 1 and the second rubber tube body 2 is smaller than the cross-section of the other end. As the first rubber tube body 1 and the second rubber tube body 2 continuously squeeze the rubber sealing plugs 5, the deformation of the rubber sealing plugs 5 becomes larger and larger, thereby making the connection sealing performance better.

[0027] Both the first hose body 1 and the second hose body 2 have rubber sealing rings 13 fixed inside their respective ends. The rubber sealing rings 13 and the rubber sealing plugs 5 work together to increase the sealing effect and prevent oil leakage during oil transportation.

[0028] The adjusting mechanism includes a bidirectional lead screw 14, which is rotatably connected to the inside of the mounting block 7 via bearings. A rotating block 15 is fixed to the rod wall of the bidirectional lead screw 14, and symmetrical sliders 16 are threaded on the rod wall of the bidirectional lead screw 14. The side walls of both sliders 16 are slidably connected to the inner wall of the mounting block 7. A fixing rod 17 is fixed to the opposite side of each of the two sliders 16. The fixing rod 17 is slidably connected to the side wall of the mounting block 7, and the opposite end of each fixing rod 17 is fixedly connected to the side wall of the locking block 8. Rotating the rotating block 15 causes the bidirectional lead screw 14 to rotate, which in turn causes the sliders 16 threaded on the rod wall to move closer together. The sliders 16 cause the fixing rods 17 on the side wall and the locking block 8 to move closer together, thereby pulling the first hose body 1 and the second hose body 2 closer together.

[0029] The two annular plates 6 have disassembly slots at both the front and rear ends, which facilitates the movement of the two clips 8 to the two ends of the two annular plates 6 during installation.

[0030] Working principle:

[0031] Install the fixing tube 3 between the first hose body 1 and the second hose body 2. Move the first hose body 1 and the second hose body 2 closer together so that one end of the first hose body 1 and the second hose body 2 is engaged with the rubber sealing plug 5. Move the locking block 8 to both sides of the annular locking plate 6 by disassembling the slot position. Rotate the rotating block 15. The rotating block 15 drives the bidirectional screw 14 to rotate. The bidirectional screw 14 drives the slider 16 connected by the screw thread on the rod wall to move. The slider 16 drives the fixing rod 17 on the side wall to move. The fixing rod 17 drives the locking block 8 on the side wall to move, so that the locking block 8 is engaged with the slot on the side wall of the annular locking plate 6, quickly connecting and fixing the first hose body 1 and the second hose body 2, and facilitating disassembly.
