Description

Technical Field

[0001] This utility model belongs to the field of high-pressure hose and pipe connection technology, and in particular relates to a high-pressure hose and pipe connection device. Background Technology

[0002] High-pressure hose connection devices are mechanical connection systems specifically designed to achieve reliable sealing and quick assembly / disassembly between high-pressure hoses and other pipeline components (such as joints, valves, equipment interfaces, etc.).

[0003] Traditional high-pressure hoses are typically secured using threads. This method is inefficient and makes it difficult to quickly complete the connection. Furthermore, threaded connections require workers to carry wrenches and other tools to tighten the threads. Since high-pressure hoses often need to be disassembled and reassembled multiple times during maintenance, the threads are prone to stripping, which affects subsequent use and reduces service life. Summary of the Invention

[0004] The purpose of this invention is to provide a high-pressure hose connection device. By setting a locking mechanism, specifically after the male and female connectors are joined, pressing the handle downwards causes the locking compression block to rotate on the fixed block via an eccentric shaft and enter the annular groove. Pushing the handle forcefully causes the protrusion on the locking compression block to push and compress the connecting block, thus quickly completing the connection. This method eliminates the need for threaded connections and eliminates the need for operators to carry tools. Furthermore, repeated connection and disassembly of the male and female connectors will not cause damage. This solves the problem that traditional high-pressure hose connections typically use threaded locking, which is inefficient and difficult to complete quickly.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high-pressure hose connection device, comprising two high-pressure hoses, with a female connector and a male connector respectively installed on one side of each hose, and further comprising:

[0007] A locking mechanism is provided on the outside of the female connector. The locking mechanism includes a locking compression block on the outside of the female connector, a handle fixedly connected to the bottom of the locking compression block, eccentric shafts fixedly connected to both outer sides of the locking compression block, and a fixing block rotatably connected to the outer side of the eccentric shafts. The fixing block is fixedly connected to the surface of the female connector. A mating block is fixedly connected to the bottom of the female connector, and an annular groove is formed on the outer side of the mating block.

[0008] A limiting mechanism is disposed on the outside of the sub-joint, and the limiting mechanism is used to restrict the handle;

[0009] The sub-connector is located on the upper high-pressure hose, and the female connector is located on the lower high-pressure hose. The sub-connector and the female connector are plugged into each other.

[0010] Furthermore, the locking compression block has an arc-shaped protrusion on the side facing the mating block, and the arc-shaped protrusion on the locking compression block is adapted to the annular groove. The locking compression block passes through the female connector and extends into the interior. The protrusion on the locking compression block can smoothly compress the mating block, thereby locking and fixing the mating block.

[0011] Furthermore, an inner tube is fixedly connected to the bottom of the mating block, and a sealing gasket is fitted on the bottom of the mating block. The inner tube is inserted into the bottom of the female connector, and the bottom of the sealing gasket contacts the bottom of the inner wall of the female connector. The sealing gasket is used to seal the connection between the mating block and the female connector. The inner tube can be more stable after installation, and the mating block can squeeze the sealing gasket after installation, thereby improving the sealing effect.

[0012] Furthermore, the limiting mechanism includes a limiting ring threaded to the outside of the sub-joint, the outside of the sub-joint being provided with threads, and a plurality of protruding rods fixedly connected to the outer surface of the limiting ring, the limiting ring being disposed on the outside of the handle; the protruding rods are used to assist the limiting ring in rotating, so that the operator can exert force more effectively when using it.

[0013] Furthermore, a convex ring is fixedly connected to the outer surface of the sub-connector, and a magnetic ring is embedded in the top of the female connector. The magnetic ring contacts the bottom of the convex ring. When the mating block is mated with the female connector, the magnetic ring on the top of the female connector will contact the convex ring, thereby using the magnetic attraction effect to easily fix the sub-connector and the female connector, preventing the sub-connector and the female connector from falling off, and making it convenient for subsequent workers to squeeze the handle.

[0014] Furthermore, the arc-shaped protrusion on the docking block contacts the inner wall of the annular groove, the bottom of the inner ring of the inner tube is set with a conical surface, the top of the inner wall of the limiting ring contacts the top of the protruding ring, and after the limiting ring moves to the outside of the handle, the inner wall of the limiting ring will contact the surface of the handle.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a locking mechanism. Specifically, after the male and female connectors are joined, pressing the handle downwards causes the locking compression block to rotate on the fixed block via an eccentric shaft and enter the annular groove. By pushing the handle forcefully, the protrusion on the locking compression block pushes and squeezes the connecting block, thus quickly completing the connection. This method does not require threaded connection, and no tools are needed for operation. Furthermore, multiple connections and disassemblies of the male and female connectors will not cause damage.

[0017] 2. This utility model sets up a limiting mechanism. Specifically, after the male and female connectors are connected, the limiting ring is pulled down and rotated clockwise by the protruding rod, so that the limiting ring moves downward and moves to the outside of the locking and pressing block. At this time, multiple handles can be limited at the same time to prevent the handles from becoming loose or unfolding, thereby improving the connection effect between the male and female connectors.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a high-pressure hose connection device, including two high-pressure hoses 1, with a male connector 11 and a female connector 12 respectively installed on one side of each other, and also including:

[0029] Locking mechanism 3 is located on the outside of female connector 12. Locking mechanism 3 includes a locking compression block 31 located on the outside of female connector 12. A handle 32 is fixedly connected to the bottom of locking compression block 31. Eccentric shafts 311 are fixedly connected to both outer sides of locking compression block 31. A fixing block 312 is rotatably connected to the outer side of eccentric shafts 311. The fixing block 312 is fixedly connected to the surface of female connector 12. A mating block 33 is fixedly connected to the bottom of female connector 11. An annular groove 331 is formed on the outer side of mating block 33. The female connector 11... After aligning with the female connector 12, press the handle 32 downwards. The locking compression block 31 rotates on the fixed block 312 via the eccentric shaft 311 and enters the annular groove 331. By forcefully pushing the handle 32, the protrusion on the locking compression block 31 pushes and compresses the mating block 33, thus quickly completing the alignment. This method does not require threaded connection, and no tools are needed during operation. Furthermore, repeated connection and disassembly of the female connector 11 and female connector 12 will not cause damage.

[0030] Restriction mechanism 2 is located on the outside of sub-joint 11 and is used to restrict handle 32;

[0031] The sub-connector 11 is located on the upper high-pressure hose 1, and the female connector 12 is located on the lower high-pressure hose 1. The sub-connector 11 and the female connector 12 are plugged into each other.

[0032] The locking compression block 31 has an arc-shaped protrusion on the side facing the mating block 33. The arc-shaped protrusion on the locking compression block 31 is adapted to the annular groove 331. The locking compression block 31 passes through the female connector 12 and extends into the interior.

[0033] The bottom of the mating block 33 is fixedly connected to the inner tube 332, and the bottom of the mating block 33 is fitted with a sealing gasket 333. The inner tube 332 is inserted into the bottom of the female connector 12, and the bottom of the sealing gasket 333 contacts the bottom of the inner wall of the female connector 12. The sealing gasket 333 is used to seal the connection between the mating block 33 and the female connector 12.

[0034] The limiting mechanism 2 includes a limiting ring 21 threaded to the outside of the sub-connector 11. The sub-connector 11 has threads on its outside, and several protruding rods 22 are fixedly connected to the outer surface of the limiting ring 21. The limiting ring 21 is located on the outside of the handle 32. After the sub-connector 11 and the female connector 12 are connected, the limiting ring 21 is pulled down and rotated clockwise by the protruding rods 22, so that the limiting ring 21 moves downward and moves to the outside of the locking and pressing block 31. At this time, multiple handles 32 can be limited at the same time to prevent the handles 32 from becoming loose or unfolded, thereby improving the connection effect between the sub-connector 11 and the female connector 12.

[0035] A protruding ring 111 is fixedly connected to the outer surface of the female connector 11, and a magnetic ring 121 is embedded in the top of the female connector 12, with the magnetic ring 121 in contact with the bottom of the protruding ring 111.

[0036] The arc-shaped protrusion on the mating block 33 contacts the inner wall of the annular groove 331. The bottom of the inner ring of the inner tube 332 is set with a conical surface. The top of the inner wall of the limiting ring 21 contacts the top of the protruding ring 111. After the limiting ring 21 moves to the outside of the handle 32, the inner wall of the limiting ring 21 will contact the surface of the handle 32.

[0037] One specific application of this embodiment is:

[0038] In use, two high-pressure hoses 1 are connected via the male connector 11 and the female connector 12. The female connector 12 is then inserted into the mating block 33 on the male connector 11 in an inverted manner. This method allows multiple handles 32 to be in an extended state and moves the protrusion on the locking compression block 31 to the outside of the female connector 12. When the mating block 33 is connected to the female connector 12, the magnetic ring 121 on the top of the female connector 12 will contact the protruding ring 111, thereby using the magnetic attraction effect to easily fix the male connector 11 and the female connector 12, preventing them from falling off and facilitating subsequent compression of the handles 32 by the operator. At the same time, after connection, the inner tube 332 on the mating block 33 will be inserted into the female connector 12, and the sealing gasket 333 will be inserted into the inner tube of the female connector 12. After the wall contacts, the female connector 12 is flipped so that the opening of the female connector 12 faces upward. At this time, the operator can press the handle 32 downward. The locking compression block 31 rotates on the fixed block 312 through the eccentric shaft 311, and the protrusion on the locking compression block 31 will enter the annular groove 331. By pushing the handle 32 forcefully, the protrusion on the locking compression block 31 will push and squeeze the mating block 33. At this time, the sealing gasket 333 will be squeezed. Through the squeezing of the locking compression block 31, the male connector 11 and the female connector 12 can be quickly mated. This method does not require the use of threads for connection, and the operator does not need to carry tools during operation. At the same time, there will be no damage from connecting and disassembling the male connector 11 and the female connector 12 multiple times.

[0039] After the female connector 11 and the female connector 12 are finally connected, pull the limiting ring 21 downward and rotate it clockwise through the protruding rod 22, so that the limiting ring 21 moves downward and moves to the outside of the locking compression block 31. At this time, multiple handles 32 can be restricted at the same time to prevent the handles 32 from becoming loose or unfolded, thereby improving the connection effect between the female connector 11 and the female connector 12. When it is necessary to disconnect the two high-pressure hoses 1, rotate the limiting ring 21 counterclockwise so that it moves upward and disengages from the handle 32. Then, pry the handle 32 upward so that it drives the locking compression block 31 away from the annular groove 331, thereby releasing the fixation of the docking block 33. Finally, pull the two to make the docking block 33 disengage from the female connector 12, thereby quickly completing the disassembly.
