[0002] Hydraulic pipe fittings are components in hydraulic systems that connect high-pressure oil pipes. Hydraulic pipe fittings can be divided into hydraulic hoses, quick connectors and ferrule-type pipe fittings. They are widely used in hydraulic pipeline systems in various industries such as military industry, energy, petrochemicals, electric power, ships, automobiles, rail transit, construction machinery, mining, metallurgy, steel mills, and marine engineering.

[0003] In the process of using the hydraulic pipe ferrule, a transition joint is needed to receive the ferrule, so as to cooperate with the transition joint to realize the connection of the oil pipe.

However, most of the existing sealing gaskets are directly put on the outer surface of the transition joint, and no corresponding measures are taken to fix the sealing gasket. As a result, the sealing gasket on the transition joint is easy to loosen and lose when it is in use, thereby causing a waste of resources. Therefore, it is necessary to improve this.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 7 As shown, the utility model provides a hydraulic ferrule transition joint, comprising:

There are two vertical plates 405, and the outer surfaces of the two vertical plates 405 are movably sleeved with the inner surface of the top of the fixed block 1, and the vertical plate 405 will cause the rotating rod 402 to rotate.

[0036] When the vertical plate 405 moves upward along the inner surface of the top of the fixed block 1, it will move with the round rod 404, so that the outer surface of the round rod 404 generates a thrust on the inner surface of the rotating rod 402, pushing the rotating rod 402 to rotate around the circular shaft 401.

[0037] Wherein, the rotating mechanism 5 comprises:

[0038] A fixing plate 501, the fixing plate 501 is fixedly sleeved on the top of the middle end of the top inner part of the fixing block 1, a threaded rod 502 is movably sleeved inside the fixing plate 501, and the bottom end of the threaded rod 502 is movably sleeved on the bottom of the inner surface of the top of the fixing block 1;

[0041] When the handle 503 is turned, the threaded rod 502 will rotate, so that the horizontal plate 504 threadedly connected with the threaded rod 502 will move along the inner surface of the top of the fixing block 1 with the vertical plate 405.

[0042] The left and right inner walls of the top of the fixed block 1 are respectively provided with slide grooves 6 , the bottom of the slide groove 6 is movably sleeved with a slider 7 , and the outer surface of the slider 7 is fixedly connected to the outer surface of the horizontal plate 504 .

[0043] The cooperation between the slide groove 6 and the slider 7 will limit the movement of the cross plate 504 .

[0044] Among them, a limit ring 8 is fixedly sleeved at the middle end inside the transition joint body 2, a scraper 9 is movably sleeved at the bottom of the outer surface of the limit ring 8, and the outer surface of the scraper 9 is movably connected to the inner surface of the transition joint body 2.

[0045] Due to the existence of the scraper 9, the inner wall of the transition joint body 2 will be cleaned when the scraper 9 moves.

[0046] The scraper 9 has a movable block 10 movably sleeved inside, an extension rod 11 is fixedly mounted on the left end of the movable block 10 , and the left end of the extension rod 11 penetrates the scraper 9 and extends to the outside of the scraper 9 .

[0047] When the extension rod 11 moves, the movable block 10 will move along with it.

[0048] Among them, a handle 12 located outside the scraper 9 is fixedly installed on the left side of the top of the extension rod 11, and a spring 13 is fixedly installed on the right end of the movable block 10. The other end of the spring 13 is fixedly connected to the right inner wall of the scraper 9. The handle 12 will drive the extension rod 11 to move.

[0049] When the handle 12 is pulled, the handle 12 and the extension rod 11 will move to the left along the inner surface of the scraper 9 .

[0050] Among them, a limiting groove 14 is opened on the left side of the bottom end inside the transition joint body 2, and the right end inside the limiting groove 14 is movably connected to the limiting block 15, the top of the limiting block 15 is fixedly connected to the left side of the bottom end of the extension rod 11, and the right end of the limiting block 15 is movably connected to the left end of the scraper 9.

[0052] The working principle and use process of this utility model:

[0053] First, after the operator has put the sealing gasket 3 on the outer surface of the transition joint body 2 and brought it into contact with the outer surface of the fixing block 1, he turns the handle 503 to rotate the threaded rod 502. At this time, the horizontal plate 504 threadedly connected to the threaded rod 502 will move upward along the inner surface of the top of the fixing block 1 through the vertical plate 405, carrying the round rod 404, so that the outer surface of the round rod 404 generates an upward thrust on the inner wall of the rotating rod 402, pushing the rotating rod 402 to rotate with the tooth 403 around the circular shaft 401 as the axis until the tooth 403 and the sealing gasket 3 are tightly fitted, thereby fixing the sealing gasket 3 and preventing the sealing gasket 3 from loosening and falling off and causing the loss of the sealing gasket 3.

[0054] When the transition joint is used, the operator pulls the handle 12, so that the handle 12 moves to the left along the inner surface of the scraper 9 with the extension rod 11 and the movable block 10 and stretches the spring 13. At this time, the limit block 15 fixedly connected to the extension rod 11 will move along the inner surface of the limit groove 14. When the limit block 15 and the limit groove 14 are separated, the operator turns the handle 12, and the scraper 9 can be rotated along the outer surface of the limit ring 8 through the extension rod 11, and the scraper 9 is movably connected to the inner wall of the transition joint body 2. Therefore, as the scraper 9 rotates, the inner wall of the transition joint body 2 will be cleaned. When the cleaning is completed, the operator aligns the limit block 15 with the limit groove 14 and releases the handle 12. Under the restoring action of the spring 13, the movable block 10 will restore the extension rod 11, the handle 12 and the limit block 15 to the original position, so that the limit block 15 is embedded in the limit groove 14, and then the scraper 9 is locked in position through the extension rod 11, so that the inner wall of the transition joint body 2 can be cleaned, thereby facilitating the next use of the hydraulic ferrule transition joint.
