Description

Technical Field

[0001] This invention relates to the field of metal hose technology, and more particularly to a high-sealing metal hose that is easy to install and connect. Background Technology

[0002] Metal hoses are widely used in numerous industries such as military, petroleum, chemical, power, metallurgy, printing, papermaking, and domestic heating and construction. They are suitable for pipeline systems that transport fluid media in various locations. Metal hoses are generally composed of stainless steel corrugated pipes, stainless steel braided sleeves, and fittings. In actual use, metal hoses need to be bent to accommodate pipeline connection and installation requirements. However, when existing metal pipes are bent and deformed excessively, the pipes are prone to damage or deformation, leading to media leakage or blockage. In addition, during use, the metal hoses shake under the impact force when the media is started and stopped, causing the metal hose connections to loosen easily and resulting in poor sealing. Therefore, a metal hose with high sealing performance that is easy to install and connect is proposed. Summary of the Invention

[0003] To address the technical problems of existing metal pipes being easily damaged or deformed when bent excessively, leading to media leakage or blockage, and metal hoses shaking under impact when the media is started and stopped, causing the metal hose connection to loosen easily and resulting in poor sealing, this invention provides a metal hose with high sealing performance that is easy to install and connect.

[0004] The present invention is achieved by the following technical solution: a metal hose with high sealing performance that is easy to install and connect, comprising a metal corrugated inner tube, a metal hose mesh sleeve provided on the outer ring of the metal corrugated inner tube, both ends of the metal hose mesh sleeve being fixedly sleeved with end connecting portions that are fixedly connected to the metal corrugated inner tube, the end connecting portions being connected to a locking drive mechanism, the outer ring of the metal hose mesh sleeve abutting against a pull-lock assembly distributed in an array along its axis, and a tensioning rod with an arc-shaped structure connecting adjacent pull-lock assemblies; The zipper assembly includes a smoothing mechanism and a deflection mechanism, and the smoothing mechanism and the deflection mechanism are slidably connected. The smoothing mechanism includes a long strip-shaped base plate. One end of the base plate has a channel, and the bottom of the channel has a receiving cavity located inside the base plate. The bottom of the receiving cavity has a circular deflection cavity, which extends from the bottom of the base plate. The inner walls of both ends of the deflection cavity have a limiting channel coaxially arranged with its axis. The limiting channel is slidably connected to a guide rod. One end of the guide rod extending out of the limiting channel is fixedly connected to a movable plate that is slidably connected to the deflection mechanism. The end of the movable plate away from the guide rod is fixedly connected to a ring-shaped snap ring. The end of the movable plate near the guide rod is fixedly connected to an airbag one that is fixedly connected to the inner wall of the end of the deflection cavity. The inner walls on both sides of the receiving cavity have inwardly recessed mounting grooves. The inner wall of the mounting groove is fixedly connected to an airbag two. The other side of the airbag two is fixedly connected to a pressing plate that is slidably connected to the mounting groove. The inner wall of the top of the receiving cavity is fixedly connected to an airbag three that abuts against the deflection mechanism. The deflection mechanism includes a rotating rod that is slidably sleeved with the deflection cavity. An extension plate extending from the bottom of the base plate is fixedly connected to the bottom of the rotating rod. A baffle is fixedly connected to the outer ring of the other end of the extension plate. A transition groove is provided on the top of the side of the rotating rod away from the extension plate. A second channel is provided through the bottom of the transition groove along the diameter direction of the rotating rod. A third channel is provided through the extension plate and communicates with the second channel. A fourth channel is provided through the rotating rod along its axis and communicates with the second channel. A connecting groove is provided at both ends of the fourth channel and is located on the rotating rod. The connecting groove is slidably connected to the movable plate.

[0005] The above technical solution involves pre-connecting the end connection to the pipe using mounting bolts, then adjusting the locking drive mechanism to make it contact the flange on the pipe. The metal hose is then fixed using mounting bolts. During fixing, the locking drive mechanism is moved, and the negative pressure of the locking drive mechanism is used to lock and shape the pull-lock assembly and tension rod surrounding the metal hose, thus tightening the metal hose from the outside.

[0006] As a further improvement to the above solution, the end connection includes a mounting plate that is fixedly connected to the metal corrugated inner tube and the metal flexible mesh sleeve. The mounting plate has a distribution cavity with an annular structure coaxially arranged therein, and an inwardly recessed abutment groove is opened on the outer side of the mounting plate. The mounting plate has a through connection hole.

[0007] As a further improvement to the above solution, the locking drive mechanism includes a sleeve fixedly connected to the end connection part, an L-shaped push-pull rod slidably connected to the other end of the sleeve, a rotating shaft movably connected to one end of the push-pull rod extending out of the sleeve, a connecting seat fixedly connected to the rotating shaft, an L-shaped adjusting rod fixedly connected to the connecting seat, and a blocking block fixedly connected to the other end of the adjusting rod.

[0008] Through the above technical solution, rotating the adjusting rod causes it to deflect towards the mounting plate, so that the adjusting rod deflects onto the contact groove on the mounting plate. Then, rotating the locking screw located on the push-pull rod causes the locking screw to extend into the locking hole on the rotating shaft to limit the rotation of the shaft and prevent it from rotating. During installation, because the end of the adjusting rod abuts against the end surface of the flange on the connecting pipe, and the blocking block abuts against the outer ring of the flange, the flange is restricted from tilting during installation. When the flange on the pipe approaches the mounting plate, the flange pushes the adjusting rod to move, and then the adjusting rod drives the push-pull rod to move. At this time, the push-pull rod extends outward from the sleeve, thereby reducing the internal pressure of the sleeve.

[0009] As a further improvement to the above solution, the cross-sectional structure of the limiting channel and the guide rod is consistent and is a regular polygonal structure. The locking ring is fixed with locking teeth distributed sequentially along its axial direction. The inner side wall of the end of the connecting groove is provided with a locking groove distributed along the rotating rod array, and the locking teeth and the locking groove are engaged.

[0010] As a further improvement to the above solution, the side of the extrusion plate away from the airbag is fixedly connected with a locking tooth two arranged along its length direction, and the baffle is provided with an inwardly recessed locking groove two, and the locking groove two engages with the locking tooth two.

[0011] As a further improvement to the above solution, the mounting plate is fixedly sleeved with the adjacent substrate and / or extension plate, and the distribution cavity is connected to channel one and channel three.

[0012] As a further improvement to the above solution, the tensioning rod is coaxially arranged with the metal flexible mesh sleeve, the tensioning rod is fixedly connected to the outer wall of the adjacent substrate, and the tensioning rod is distributed on one side of the extension line of the adjacent channel four.

[0013] As a further improvement to the above solution, the third airbag abuts against the top of the adjacent baffle, and the third airbag and the first airbag have a ring structure.

[0014] As a further improvement to the above solution, the deflection cavity and the rotating rod are arranged perpendicular to the diameter direction of the metal flexible mesh sleeve, and the smoothing mechanism and the deflection mechanism are arranged alternately.

[0015] As a further improvement to the above solution, the inner ring of the corrugated metal tube is fitted with a wear-resistant sleeve that abuts against the outer ring of the metal flexible mesh sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention reinforces and locks the metal hose during installation and connection, improving the overall strength of the metal hose and preventing flange misalignment. It also provides positioning constraints during installation, facilitating installation and connection.

[0017] A stable annular mesh reinforcement structure is formed on the outer ring of the metal hose to prevent excessive bending and deformation of the metal hose. This effectively prevents damage or blockage caused by excessive bending. The metal hose is reinforced and fixed to prevent collisions or connection detachment caused by shaking during use, thereby improving the tightness of the metal hose connection and enhancing the sealing safety of the metal hose.

[0027] Mounting plate 31 is fixedly sleeved with adjacent substrate 21 and / or extension plate 44, and distribution cavity 34 is connected to channel 1 22 and channel 3 47.

[0028] Example 3

[0029] Based on Embodiment 1, this embodiment is further improved in that: the cross-sectional structure of the limiting channel 25 and the guide rod 26 are the same and both are regular polygonal structures; the snap ring 28 is fixed with snap teeth distributed sequentially along its axial direction; the inner side wall of the end of the connecting groove 42 is provided with a snap groove distributed in an array along the rotating rod 41, and the snap teeth are snapped into the snap groove.

[0030] The compression plate 212 is fixedly connected to a locking tooth 2 along its length on the side away from the airbag 211. The baffle 45 is provided with an inwardly recessed locking groove 2, and the locking groove 2 engages with the locking tooth 2.

[0031] The tension rod 6 is coaxially arranged with the metal flexible mesh sleeve 1. The tension rod 6 is fixed to the outer wall of the adjacent base plate 21. The tension rod 6 is distributed on one side of the extension line of the adjacent channel 48.

[0032] Airbag 3 213 abuts against the top of the adjacent baffle 45, and airbag 3 213 and airbag 1 29 are annular structures.

[0033] The deflection cavity 24 and the rotating rod 41 are arranged perpendicular to the diameter direction of the metal flexible mesh sleeve 1, and the smoothing mechanism 7 and the deflection mechanism 8 are arranged alternately.

[0034] The inner ring of the metal corrugated inner tube 2 is fitted with a wear-resistant sleeve that abuts against the outer ring of the metal flexible mesh sleeve 1.

[0035] Working principle: First, adjust the bending shape of the metal hose according to the position of the pipes connected to both ends of the metal hose. Then, pre-connect the end connection 3 to the pipe to be connected by the mounting bolts. After that, adjust the state of the locking drive mechanism 4 so that the locking drive mechanism 4 abuts against the flange on the pipe to be connected. Then, use the mounting bolts to fix the metal hose. When fixing, push the locking drive mechanism 4 to move. Use the negative pressure of the locking drive mechanism 4 to fix and lock the pull lock assembly 5 and the tension rod 6 around the metal hose, so that the pull lock assembly 5 tightens the metal hose from the outside. When the metal hose bends, the zipper assembly 5 deflects and extends under the combined action of the tension rod 6. At this time, the extension plate 44 slides along the length of the receiving cavity 23, and the rotating rod 41 deflects relative to the deflection cavity 24. The extension and deflection method is used to adapt to the bending deformation of the metal hose. With the cooperation of the tension rod 6, the zipper assembly 5 is attached to the outer surface of the metal hose. When the zipper assembly 5 is locked, it can lock and protect the metal hose. When adjusting the state of the locking drive mechanism 4, rotate the adjusting rod 53 to deflect it toward the mounting plate 31, so that the adjusting rod 53 deflects onto the contact groove 32 on the mounting plate 31. Then rotate the locking screw located on the push-pull rod 52, so that the locking screw extends into the locking hole on the rotating shaft 55 to limit the rotating shaft 55 and prevent it from rotating. During installation, the end of the adjusting rod 53 abuts against the end surface of the flange on the connecting pipe, and the blocking block 54 abuts against the outer ring of the flange, limiting the flange from tilting during installation. When the flange on the pipe approaches the mounting plate 31, the flange pushes the adjusting rod 53 to move, and then the adjusting rod 53 drives the push-pull rod 52 to move. At this time, the push-pull rod 52 extends outward of the sleeve 51, thereby reducing the internal pressure of the sleeve 51. While performing the installation connection, the metal hose is reinforced and locked, improving the overall strength of the metal hose and preventing the flange from tilting. Positioning is limited during installation, which facilitates the installation connection. When the pressure inside the sleeve 51 decreases, the liquid medium filling the sleeve 51, distribution cavity 34, and pull-lock assembly 5 flows into the sleeve 51. At this time, the liquid medium in the pull-lock assembly 5 enters the distribution cavity 34 along channel 1 22 and channel 3 47, and then enters the sleeve 51. As the liquid medium is discharged, the pressure in the receiving cavity 23, channel 2 46, and channel 48 decreases. Then, the two sets of extrusion plates 212 move closer to each other in opposite directions. The extrusion plates 212 contact the baffle 45, causing the extrusion plates 212 to engage with the baffle 45 and lock the baffle 45. At this time, the extension plate 44 cannot slide along its length. At the same time, the two sets of movable plates 27 move to one side closer to each other, causing the locking ring 2 on the movable plate 27 to engage with the baffle 45. The 8 abuts against the inner side wall of the end of the connecting groove 42 on the rotating rod 41, and then the snap ring 28 snaps into the rotating rod 41 to lock the rotating rod 41, so that the rotating rod 41 does not deflect, thus completing the locking operation between the smoothing mechanism 7 and the deflection mechanism 8. When in use, the pull lock assembly 5 and the tensioning rod 6 form a stable annular mesh reinforcement structure on the outer ring of the metal hose. On the one hand, it avoids excessive bending deformation of the metal hose, effectively preventing the metal hose from being damaged or blocked due to excessive bending. On the other hand, it reinforces and fixes the metal hose, effectively preventing the metal hose from shaking during use and causing collisions or connection detachment, improving the tightness of the metal hose connection and improving the sealing safety of the metal hose.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
