Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-pressure hose technology, specifically to a self-locking pressure-resistant and explosion-proof high-pressure hose. Background Technology
[0002] High-pressure hoses, as a type of pipe capable of withstanding high-pressure loads, are widely used in mechanized and automated hydraulic systems such as mine hydraulic supports, oil field development, and engineering construction. Their main function is to transport petroleum-based and water-based liquids with certain pressures and temperatures. Since these application environments typically require systems to have high safety and stability, the performance of high-pressure hoses, as one of the key components, is particularly important.
[0003] However, existing technologies for connecting high-pressure hoses have some significant shortcomings. Firstly, traditional high-pressure hose connection methods are often complex, requiring numerous steps and tools, resulting in slow connection speeds. This not only affects work efficiency but also increases installation and maintenance costs to some extent. Secondly, under extreme conditions such as high pressure or vibration, the joints of high-pressure hoses are prone to loosening. This loosening can lead to fluid leakage, wasting resources and causing environmental pollution. It can also cause pressure fluctuations in the hydraulic system, affecting its normal operation and even triggering safety accidents.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a self-locking pressure-resistant and explosion-proof high-pressure hose to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A self-locking, pressure-resistant, explosion-proof high-pressure hose includes a first hose connector and a second hose connector on one side of the first hose connector. Both the first and second hose connectors are fixedly connected to the hose body. A shrinkage groove is formed on the inner wall of the first hose connector, and a telescopic spring is fixedly connected inside the shrinkage groove. A positioning post is fixedly connected to the end of the telescopic spring. A limit ring is slidably installed inside the first hose connector. A positioning groove is formed at one end of the second hose connector, and the positioning post cooperates with the positioning groove. The limit ring is slidably installed on one side of the shrinkage groove.
[0008] Furthermore, in order to achieve the automatic reset effect of the limit ring, a support ring is fixedly connected to one side of the inner wall of the first hose connector, and a telescopic spring is fixedly connected to one end of the support ring. One end of the telescopic spring is fixedly connected to the limit ring.
[0009] Further, in order to facilitate the disassembly of the two connected rubber pipe joints, one end of the positioning column is fixedly connected with a transmission rod, the distal end of the transmission rod is slidably connected with a lifting block, the outer surface of the first rubber pipe joint is threadedly connected with a push frame, one side of the push frame is rotatably connected with a disassembly frame, and the side surface of the disassembly frame is slidably connected with the side surface of the lifting block.
[0010] Further, in order to improve the stability of the connection of the two rubber pipe joints, a sliding groove is formed in the inner wall of one side of the second rubber pipe joint, a third telescopic spring is fixedly connected in the sliding groove, and the distal end of the third telescopic spring is fixedly connected with a reinforcing plate; a limiting groove is formed in the inner wall of one side of the first rubber pipe joint, and one end of the reinforcing plate is matched with the limiting groove.
[0011] Further, in order to improve the sealing performance of the two rubber pipe joints, the first rubber pipe joint and the second rubber pipe joint are both fixedly connected with a rubber ring at one end.
[0012] Further, in order to facilitate the screwing of the push frame, screwing rods are fixedly connected to the outer surface of the push frame.
[0013] Further, in order to facilitate the push-pull movement of the second rubber pipe joint and the contact connection of the two rubber pipe joints and the high-pressure rubber pipe, a dismounting ring is fixedly connected to the outer surface of one side of the second rubber pipe joint.
[0014] The utility model discloses the beneficial effects are:
[0015] When one end of the second rubber pipe joint is matched and installed in the first rubber pipe joint, the second rubber pipe joint can push the limiting ring to move, so that the limiting ring no longer blocks the positioning column in the contraction groove after sliding; when the positioning groove at one end of the second rubber pipe joint is correspondingly moved to one side of the positioning column, the elastic force of the first telescopic spring can push the positioning column to be matched and installed in the positioning groove, realizing the quick connection and self-locking function of the two rubber pipe joints, and greatly improving the connection efficiency and anti-loosening effect of the high-pressure rubber pipe.
[0016] When the two rubber pipe joints are connected with each other, one end of the reinforcing plate slidably installed in the second rubber pipe joint can be correspondingly arranged at one side of the limiting groove; and when the two rubber pipe joints are conveying high-pressure liquid, the pressure of the liquid can push one end of the reinforcing plate to shrink into the sliding groove; at this time, one end of the reinforcing plate in the first rubber pipe joint can be matched and installed in the limiting groove, thereby further improving the stability of the connection of the two rubber pipe joints.
