Description

Technical Field

[0001] The utility model belongs to the field of hydraulic parts, and particularly relates to a hydraulic pipe fitting which is convenient to disassemble. Background Art

[0002] Hydraulic pipe fittings are mainly used to transport pressurized liquids. The hydraulic pipe fittings currently on the market require both hands to hold the pipe fittings separately when disassembling. One hand is used to unlock the pipe, and the other hand is used to pull out and separate the pipe fitting. When unlocking, it is necessary to keep holding the locking part until the pipe fitting is separated before letting go. This operation is relatively laborious. When both hands cannot work together, this disassembly action is more complicated to perform with one hand. Summary of the invention

[0003] The utility model aims to provide a hydraulic pipe fitting which is easy to disassemble 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 hydraulic pipe fitting that is easy to disassemble, comprising two mutually clamped pipe fittings 1 and 2, characterized in that the pipe fitting 1 is provided with an annular groove for inserting the pipe fitting 2, the annular groove wall is provided with an arc plate that can be telescoped inward, the front end of the pipe fitting 2 is provided with a ring for fitting with the arc plate, and the outer side of the pipe fitting 2 is provided with a slidable sliding ring;

[0005] The sliding ring is provided with shaft one, the pipe fitting two is provided with shaft two, a connecting rod for fixed connection is provided between the shaft one and the shaft two, and a support plate for abutting against the pipe fitting one is extended from one side of the shaft two toward the inside of the pipe fitting two.

[0006] In the above-mentioned hydraulic pipe fitting that is easy to disassemble, a protrusion for limiting is provided at the connection between the pipe fitting 2 and the sliding ring, a matching block arranged opposite to the protrusion is provided on the inner wall of the sliding ring, and an elastic element 1 with elastic reset function is provided between the protrusion and the matching block.

[0007] In the above-mentioned hydraulic pipe fitting that is easy to disassemble, grooves inclined at two sides are provided on the two inner walls of the pipe fitting, and the support plate can be folded in the grooves.

[0008] In the above-mentioned hydraulic pipe fitting that is easy to disassemble, a sliding groove for sliding the arc plate is arranged on the inner wall of the annular groove, a baffle is arranged at one end of the arc plate, and a second elastic element is arranged between the baffle and the sliding groove.

[0009] Compared with the prior art, the hydraulic pipe fitting that is easy to disassemble can be disassembled by only pulling the sliding ring, and there is no need to free up extra hands to pull out the pipe fitting, which simplifies the operation and greatly improves the work efficiency.

DETAILED DESCRIPTION

[0013] 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.

[0014] like Figure 1 , Figure 2 As shown, the hydraulic pipe fitting convenient for disassembly comprises two mutually clamped pipe fittings 1 and 2, the pipe fitting 1 is provided with an annular groove 3 for inserting the pipe fitting 2, the groove wall of the annular groove 3 is provided with an arc plate 4 which can be telescoped inward, the front end of the pipe fitting 2 is provided with a circular ring 5 for being engaged with the arc plate 4, and the outer side of the pipe fitting 2 is provided with a slidable sliding ring 6;

[0015] A shaft 1 7 is provided on the sliding ring 6, a shaft 2 8 is provided on the pipe 2, a connecting rod 9 for fixed connection is provided between the shaft 1 7 and the shaft 2 8, and a support plate 10 for abutting against the pipe 1 1 is extended from one side of the shaft 2 8 toward the inside of the pipe 2 2;

[0016] A protrusion 11 for limiting is provided at the connection between the pipe fitting 2 and the sliding ring 6, a matching block 12 arranged opposite to the protrusion 11 is provided on the inner wall of the sliding ring 6, and an elastic element 13 with elastic reset function is provided between the protrusion 11 and the matching block 12.

[0017] When disassembling, pull the sliding ring 6. Since the second shaft 8 is fixed on the pipe fitting 2, the shaft 1 7 will rotate and drive the connecting rod 9 when the sliding block slides. The connecting rod 9 drives the second shaft 8, so that the support plate 10 is folded toward the pipe mouth of the pipe fitting 2, and the pipe fitting 1 is pushed outward to separate the pipe fitting 1 from the pipe fitting 2.

[0018] To elaborate further, a groove 14 inclined on both sides is opened on the inner wall of the pipe 2, and the support plate 10 can be folded in the groove 14. The groove 14 leaves space for the support plate 10 to fold, preventing the support plate 10 from damaging the inner wall of the pipe 2 during the folding process.

[0019] To be more specific, a sliding groove 15 for sliding the arc plate 4 is provided on the inner wall of the annular groove 3 , a baffle 16 is provided at one end of the arc plate 4 , and an elastic element 17 is provided between the baffle 16 and the sliding groove 15 .

[0020] 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.

[0021] Although this article uses more terms such as pipe fitting 1, pipe fitting 2, annular groove 3, arc plate 4, circular ring 5, sliding ring 6, shaft 1 7, shaft 2 8, connecting rod 9, support plate 10, convex block 11, matching block 12, elastic element 1 13, channel 14, sliding groove 15, baffle 16, elastic element 2 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.
