Description

Technical Field

[0001] The utility model belongs to the field of hydraulic parts, and particularly relates to a sealed hydraulic pipe. Background Art

[0002] Hydraulic pipes are often used in the connection of various hydraulic parts to provide a flow channel for the medium. When using hydraulic pipes, the connection method and whether the connection is sealed to prevent the medium from flowing out are usually considered. Traditional hydraulic pipes mostly adopt a plug-in structure, and most of these structures use sliding locking components. During use, it is easy to disconnect the pipe due to accidental touch, resulting in leakage of the medium in the pipe. Summary of the invention

[0003] The utility model aims to provide a sealed hydraulic pipe in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a sealed hydraulic pipe, comprising two pipe fittings 1 and 2 that can be clipped together, characterized in that one end of the pipe fitting 2 is provided with two clip joints for clipping together with the pipe fitting 1, and the clip joint is provided with two annular protrusions arranged in upper and lower positions, one end of the pipe fitting 1 is provided with a matching groove for inserting the clip joint, and the inner wall of the matching groove is provided with a plurality of matching blocks for matching with the protrusions, and the matching blocks are arranged in groups of two in upper and lower positions, and a groove for clipping with the protrusions is formed therebetween, the pipe fitting 1 is provided with an axially foldable buckle inside, and the pipe fitting 2 is provided with a groove for inserting the pipe fitting 1, and the groove is provided with a clip groove for matching with the buckle.

[0005] In the above-mentioned sealed hydraulic pipe, a locking nut is arranged on the pipe fitting, and a circular ring-shaped baffle extending outward is arranged on one side of the locking nut.

[0006] In the above-mentioned sealed hydraulic pipe, a limiting portion for abutting against the baffle and being limited by the locking nut is provided on an outer wall of the pipe.

[0007] In the above-mentioned sealed hydraulic pipe, the lower end of the buckle extends toward an outer wall of the pipe fitting to form a sliding block which can abut against the baffle and drive the buckle to fold axially, and one side of the sliding block is inclined.

[0008] In the above-mentioned sealed hydraulic pipe, a receiving groove for receiving the matching block is provided on an inner wall of the pipe, and an elastic element with elastic reset function is arranged in the receiving groove.

[0009] In the above-mentioned sealed hydraulic pipe, a rubber pad with a sealing function is arranged on the matching block.

[0010] Compared with the existing technology, the sealed hydraulic pipe uses a locking nut to lock the connection between the pipe fittings. The mutual snap-fitting of the two pipe fittings makes the connection between the pipe fittings more stable. The locking nut also effectively prevents the pipe fitting connection from being disconnected due to accidental touch. A rubber pad is also provided at the joint inside the pipe fitting to increase the sealing of the pipe fitting connection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, the sealed hydraulic pipe comprises two pipe fittings 1 and 2 which can be clipped together. One end of the pipe fitting 2 is provided with two clip joints 3 for clipping together with the pipe fitting 1. The clip joint 3 is provided with two annular protrusions 4 arranged in upper and lower positions. One end of the pipe fitting 1 is provided with a matching groove 5 for inserting the clip joint 3. The inner wall of the matching groove 5 is provided with a plurality of matching blocks 6 for matching with the protrusion 4. The matching blocks 6 are arranged in groups of two in upper and lower positions, and grooves 7 for clipping with the protrusion 4 are formed therebetween. An axially foldable buckle 8 is provided inside the pipe fitting 1. A groove 9 for inserting the pipe fitting 1 is provided on the pipe fitting 2, and a slot 10 for matching with the buckle 8 is provided on the groove 9.

[0016] To be more specific, a locking nut 11 is provided on the pipe fitting 1, and a circular ring-shaped baffle 12 extending outward is provided on one side of the locking nut 11.

[0017] To be more specific, a limiting portion 13 is provided on the outer wall of the pipe 1 for abutting against the baffle 12 and limiting the position of the locking nut 11.

[0018] To be more specific, a sliding block 17 is extended from the lower end of the buckle 8 toward the outer wall of the pipe 1, which can abut against the baffle 12 and drive the buckle 8 to fold axially, and one side of the sliding block 17 is inclined.

[0019] To be more specific, a receiving groove 14 for receiving the matching block 6 is provided on the inner wall of the pipe 1, and an elastic element 15 with an elastic reset function is provided in the receiving groove 14.

[0020] To be more specific, a rubber pad 16 having a sealing function is provided on the matching block 6 .

[0021] When in use, loosen the locking nut 11, align the card connector 3 with the matching groove 5, and then insert the card connector 3 into the matching groove 5. At this time, the protrusion 4 pushes the matching block 6 to slide into the receiving groove 14. When the protrusion 4 passes the matching block 6, the matching block 6 is reset through the elastic element 15 and the protrusion 4 is clamped in the groove 7. When the card connector 3 enters the matching groove 5, the front end of the pipe fitting 1 also enters the groove 9. When this action is completed, tighten the limiting part 13 of the locking nut 11. At this time, the baffle 12 will push the sliding block 17 inward, and at the same time, the sliding block 17 drives the buckle 8 to fold outward and make it clamped in the card groove 10 to complete the installation.

[0022] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0023] Although this article uses more terms such as pipe fitting 1, pipe fitting 2, clamping joint 3, protrusion 4, matching groove 5, matching block 6, groove 7, buckle 8, channel 9, clamping groove 10, locking nut 11, baffle 12, limiter 13, storage groove 14, elastic element 15, rubber pad 16, sliding block 17, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
