Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pipes, and specifically belongs to an anti - detachment structure for hydraulic pipe fittings. Background Art

[0002] Hydraulic pipe fittings are used to convey hydraulic oil. Due to the large pressure that hydraulic oil can generate, the connection between two hydraulic pipes 3 will become loose, have gaps, or even become detached under the long - term action of the pressure of hydraulic oil, resulting in the leakage of hydraulic oil, which affects the normal operation of equipment and the normal progress of production. Summary of the Utility Model

[0003] In order to overcome the problems existing in the background art, the utility model provides an anti - detachment structure for hydraulic pipe fittings to solve the technical problem that the connection between two hydraulic pipes 3 will become loose and detached under the long - term action of the pressure of hydraulic oil, resulting in the leakage of hydraulic oil and affecting the normal operation of equipment.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] An anti - detachment structure for hydraulic pipe fittings includes an anti - detachment component A1 and an anti - detachment component B2 that are buckled together; the tails of the anti - detachment component A1 and the anti - detachment component B2 are respectively fixedly installed on two interconnected hydraulic pipes 3; a plurality of jacks 4 are evenly arranged at the front end of the anti - detachment component A1, and a fastener 5 with an L - shaped structure inserted into the jacks 4 is arranged at the front end of the anti - detachment component B2; there are two anti - detachment component A1 and two anti - detachment component B2 respectively; arc - shaped fixing pieces 6 that are stuck on the hydraulic pipes 3 are arranged at the tails of the two anti - detachment component A1, and both ends of the arc - shaped fixing pieces 6 are connected and fixed to the hydraulic pipes 3 through bolts 7; the anti - detachment component B2 is fixed to the other hydraulic pipe 3 by the same connection method as the anti - detachment component A1.

[0006] Preferably, a buckle plate 8 that is pressed against the fastener 5 in the opposite direction is arranged at the bottom of the front end of the anti - detachment component A1.

[0007] Preferably, a limiting plate 9 that is threadedly connected to the hydraulic pipe 3 is arranged between the arc - shaped fixing piece 6 and the connection of the two hydraulic pipes 3.

[0008] Preferably, auxiliary holes 10 are evenly opened on the end face of the limiting plate 9.

[0009] The beneficial effect of the utility model is that through the anti - detachment component A and the anti - detachment component B that are buckled together, when an outward hydraulic tensile force acts on the connection of two hydraulic pipes, the fastener of the anti - detachment component B inserted into the jack will only become tighter under the pull, thus preventing the connection of the two hydraulic pipes from becoming loose and detached, resulting in the leakage of hydraulic oil.

[0014] In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following will combine the drawings to detail the preferred embodiments of the present utility model for the convenience of those skilled in the art to understand.

[0015] As Figures 1-4 shown, the present utility model provides a hydraulic pipe fitting anti - detachment structure, which includes an anti - detachment component A1 and an anti - detachment component B2 that are buckled together; the tails of the anti - detachment component A1 and the anti - detachment component B2 are respectively fixedly installed on two interconnected hydraulic pipes 3; a plurality of jacks 4 are evenly arranged at the front end of the anti - detachment component A; a fastener 5 with an L - shaped structure inserted into the jacks 4 is arranged at the front end of the anti - detachment component B2; there are two anti - detachment component A1 and two anti - detachment component B2 respectively; arc - shaped fixing pieces 6 that are stuck on the hydraulic pipe 3 are arranged at the tails of the two anti - detachment component A1, and both ends of the arc - shaped fixing piece 6 are connected and fixed to the hydraulic pipe 3 by bolts 7; the anti - detachment component B2 is fixed to another hydraulic pipe 3 by the same connection method as the anti - detachment component A1. When this anti - detachment structure is in use, the fastener 5 at the front end of the anti - detachment component B2 is buckled into the jacks 4 at the front end of the anti - detachment component A1, so that the anti - detachment component A1 and the anti - detachment component B2 are buckled together, and then the two anti - detachment component A1 and the two anti - detachment component B2 are respectively stuck on the two hydraulic pipes 3 through the arc - shaped fixing pieces 6 at the tails, and both ends of the arc - shaped fixing piece 6 are connected and fixed by bolts 7, so that the buckling ends of the anti - detachment component A1 and the anti - detachment component B2 are tightened; when the connection part of the two hydraulic pipes 3 is subjected to an outward hydraulic tensile force, the buckling ends of the anti - detachment component A and the anti - detachment component B2 will only be tightened more and more, thereby preventing the connection part of the two hydraulic pipes 3 from loosening and detaching, resulting in hydraulic oil leakage.

[0016] A buckle plate 8 that is pressed against the fastener 5 in the opposite direction is arranged at the bottom of the front end of the anti - detachment component A1. When the fastener 5 at the front end of the anti - detachment component B2 is inserted into the jacks 4 arranged on the anti - detachment component A1, the fastener 5 is pressed against the buckle plate 8 in the opposite direction, which can increase the pressure - bearing area of the anti - detachment component A1 and the anti - detachment component B2, reduce the pressure, and thus avoid damage to the anti - detachment component A and the anti - detachment component B2 due to relatively large local pressure after long - term use.

[0017] A limiting plate 9 is threadedly connected to the hydraulic pipe 3 and is located between the arc-shaped fixing piece 6 and the connection of the two hydraulic pipes 3. When the anti-disconnection assemblies A1 and B2 are installed on the hydraulic pipe 3, the limiting plate 9 can be rotated by threading, so that the limiting plate 9 moves outwards and presses against the anti-disconnection assemblies A1 and B2 on the outside, causing the anti-disconnection assemblies A1 and B2 to generate an outward pulling force, so that the anti-disconnection assemblies A1 and B2 are fastened to each other, avoiding loosening or disconnection at the connection of the hydraulic pipe 3.

[0018] Auxiliary holes 10 are evenly formed in the end face of the limiting plate 9. When the limiting plate 9 is rotated, when the limiting plate 9 abuts against the anti-disconnection assemblies A1 and B2, resistance will be generated. A rod can be inserted into the auxiliary hole 10 to assist in rotating the limiting plate 9, so as to more labor-savingly tighten the anti-disconnection assemblies A1 and B2.

[0019] Working process:

[0020] When this anti-disconnection structure is in use, the fastener 5 at the front end of the anti-disconnection assembly B2 is buckled into the jack 4 at the front end of the anti-disconnection assembly A1, so that the anti-disconnection assemblies A1 and B2 are buckled together. Then, the two anti-disconnection assemblies A1 and the two anti-disconnection assemblies B2 are respectively clamped on the two hydraulic pipes 3 through the arc-shaped fixing pieces 6 at the tail ends. The two ends of the arc-shaped fixing piece 6 are connected and fixed by bolts 7. Then, the limiting plate 9 is rotated by threading, so that the limiting plate 9 moves outwards and presses against the anti-disconnection assemblies A1 and B2 on the outside, causing the anti-disconnection assemblies A1 and B2 to generate an outward pulling force, so that the anti-disconnection assemblies A1 and B2 are fastened to each other, avoiding loosening or disconnection at the connection of the hydraulic pipe 3; when an outward hydraulic pulling force is applied to the connection of the two hydraulic pipes 3, the buckling ends of the anti-disconnection assemblies A and B2 will only be pulled tighter and tighter, thereby preventing loosening and disconnection at the connection of the two hydraulic pipes 3 and causing hydraulic oil leakage.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
