Description

Technical Field

[0001] This utility model relates to the field of rubber hoses, specifically a quick-connect flame-retardant hydraulic rubber hose. Background Technology

[0002] Rubber hoses play an indispensable role in both industrial production and daily life. Early on, limited by materials and processes, rubber hoses had limited performance, were prone to aging, and were not resistant to high temperatures and pressures, resulting in a narrow range of applications. With rapid industrial development, various fields have placed more stringent demands on rubber hoses. In automobile manufacturing, rubber hoses around the engine must withstand high temperatures, oil corrosion, and mechanical vibration, which traditional rubber hoses cannot handle. In the chemical industry, when transporting corrosive liquids, ordinary rubber hoses are easily corroded, leading to leaks, safety hazards, and environmental pollution. To solve these problems, researchers have continuously explored new rubber materials, such as hydrogenated nitrile rubber, which significantly improves oil resistance and heat resistance. In terms of processing, improvements in vulcanization technology and strengthening the adhesion between the reinforcing material and the rubber have enhanced the pressure resistance and fatigue resistance of rubber hoses. Today, high-performance rubber hoses are widely used in high-end fields such as aerospace and new energy, and their performance still has significant room for improvement in the future.

[0003] An existing quick-connect flame-retardant hydraulic rubber hose has a threaded end. When the flame-retardant hydraulic rubber hose needs to be connected, a threaded fixing block is fitted onto the ends of the two sets of flame-retardant hydraulic rubber hoses. By rotating the threaded fixing block, the two sets of flame-retardant hydraulic rubber hoses can be quickly connected.

[0004] However, for existing quick-connect flame-retardant hydraulic rubber hoses, the lack of effective sealing components at the ends results in poor sealing when the hoses are fixed by threaded fixing blocks, affecting the effectiveness of the device. Furthermore, the threaded fixing blocks require a certain amount of time to use, failing to achieve a quick connection and hindering the widespread use of the device. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a quick-connect flame-retardant hydraulic rubber hose to solve the technical problem mentioned in the background art of the poor performance of existing quick-connect flame-retardant hydraulic rubber hoses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect flame-retardant hydraulic rubber hose, comprising a hose body, a first mounting base at one end of the hose body, a sealing ring fixedly mounted on the inner wall of the first mounting base, a limit ring on one side of the first mounting base, a first limiting block on one side of the first mounting base, a first slot on one side of the first mounting base, a through groove formed in the first mounting base and the first limiting block, a first side groove and a second side groove formed on one side of the first limiting block, a second mounting base at the other end of the hose body, a limit groove on one side of the second mounting base, a second limiting block fixedly mounted on one side of the second mounting base, a second slot on one side of the second mounting base, a second locking block movably mounted in the second slot, the second locking block fixedly mounted on one side of the mounting block, a first locking block fixedly mounted on the other side of the mounting block, and an inclined block between the first locking block and the mounting block.

[0007] By adopting the above technical solution, the problem of poor performance of existing quick-connect flame-retardant hydraulic rubber hoses mentioned in the background art is solved. A first mounting base is provided at one end of the hose body, and a first limiting block is provided on one side of the first mounting base. A second mounting base and a second limiting block are also provided at the other end of the hose body. When two sets of hose bodies need to be spliced, the second mounting base and the first mounting base are fitted together, and then a second locking block on one side of the mounting block is fitted into a second locking groove between the hose body and the second limiting block. One end of the mounting block is fitted into a through groove opened in the first mounting base and the first limiting block. Then, the mounting block is rotated, so that the second locking block on one side of the mounting block... The first locking block is engaged inside the first locking groove. The inclined block between the mounting block and the first locking block fits into the first side groove on one side of the first limiting block. The fitting edges of the inclined block and the first side groove are both set as inclined surfaces. After the mounting block is rotated to the designated position, the inclined block will be engaged in the second side groove on one side of the first limiting block. The second side groove can fix the mounting block and prevent the mounting block from rotating at will. At the same time, by stretching the mounting block when rotating, the mounting block can provide a squeezing force on the first limiting block and the second limiting block, so that the first mounting base and the second mounting base can fit tightly together.

[0010] The present invention is further configured such that the diameter of the first mounting base is the same as that of the first side groove, and the inner wall of the mounting block and the outer wall of the first mounting base fit together.

[0011] Preferably, by setting the diameter of the first mounting base and the first side groove to be the same, and by having the inner wall of the mounting block and the outer wall of the first mounting base and the first side groove fit together, the mounting block can be stably installed on the outer wall of the first mounting base, thereby achieving effective fixation.

[0012] The present invention is further configured such that the through groove and the mounting block are arranged in a fan shape, and one end of the mounting block is sleeved inside the through groove.

[0013] Preferably, the through groove and the mounting block are arranged in a fan shape, with one end of the mounting block fitted inside the through groove, so that the mounting block can rotate.

[0014] The present invention is further configured such that the mounting block is a U-shaped block, and the first locking block and the second locking block are fixedly installed on the inner wall of the mounting block.

[0015] Preferably, by setting the mounting block as a U-shaped block, the first and second locking blocks are fixedly installed on the inner wall of the mounting block, so that the mounting block can play a locking role, thereby achieving the desired effect.

[0016] The present invention is further configured such that the thickness of the inclined block is the same as the thickness of the first limiting block, and the height of the inclined block is less than the height of the first locking block.

[0017] Preferably, by setting the thickness of the inclined block to be the same as the thickness of the first limiting block, the installation block is prevented from becoming loose, and the height of the inclined block is less than the height of the first locking block, so that the first locking block can be locked in the first locking groove.

[0018] The present invention is further configured such that one end of the inclined block is fitted with the first side groove, and the inclined block and the first side groove have the same inclination angle as the second side groove.

[0019] Preferably, one end of the inclined block is attached to the first side groove, and the inclined block and the first side groove have the same inclination angle as the second side groove, which facilitates the rotation of the mounting block and enables the mounting block to play a clamping and squeezing role.

The limiting ring 21 is fitted inside the limiting groove 81 to prevent the two sets of hose bodies 1 from rotating relative to each other during installation, thereby affecting the installation effect of the device.

[0048] In practical operation, when two sets of hose bodies 1 need to be spliced, the second mounting base 7 and the first mounting base 3 are fitted together. Then, the second locking block 102 on one side of the mounting block 10 is fitted into the second locking groove 9 between the hose body 1 and the second limiting block 71. One end of the mounting block 10 is fitted into the through groove 4 opened in the first mounting base 3 and the first limiting block 31. Then, the mounting block 10 is rotated so that the first locking block 101 on one side of the mounting block 10 is locked into the first locking groove 6. The inclined block 103 between the mounting block 10 and the first locking block 101 is fitted into the first side groove 5 opened on one side of the first limiting block 31. The fitting edges of the inclined block 103 and the first side groove 5 are both set as inclined surfaces.

The second side groove 51 can fix the mounting block 10. The installation block 10 can be prevented from rotating freely. Simultaneously, by stretching the installation block 10 during rotation, it provides a compressive force to the first limiting block 31 and the second limiting block 71, allowing the first mounting base 3 and the second mounting base 7 to fit tightly together. This enables the two sets of hose bodies 1 to be installed quickly while providing good sealing, effectively improving the practicality of the device. Furthermore, by providing a sealing ring 2 on the inner wall of the first mounting base 3 and a limiting ring 21 on one side of the first mounting base 3, and a sealing groove 8 on the inner wall of the second mounting base 7 and a limiting groove 81 on one side of the second mounting base 7, the airtightness of the device is effectively improved when the two sets of hose bodies 1 are installed. By fitting the sealing ring 2 inside the sealing groove 8, the airtightness of the device is effectively improved. By fitting the limiting ring 21 inside the limiting groove 81, relative rotation of the two sets of hose bodies 1 during installation is prevented, thus avoiding any impact on the installation effect of the device.
