Description

Technical Field

[0001] This utility model relates to pipeline connection technology, and more particularly to a hydraulic pipeline connection component. Background Technology

[0002] Hydraulic pipes on hydraulic equipment require stable connections to prevent leaks. Currently, some hydraulic pipe connections use elastic clamps, but these are easily pulled out under pressure. Threaded tightening methods are susceptible to loosening due to equipment vibration, leading to leaks. Therefore, a hydraulic pipe connection assembly that is easy to install and remove while providing a stable connection is needed. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a hydraulic pipeline connection assembly.

[0005] The housing has an interior hollowed out to form an installation area, and the lower end of the installation area is open;

[0006] A limiting member is disposed inside the housing, the limiting member is hinged in the installation area by a first hinge rod, the housing is provided with a through hole that mates with the limiting member, and the upper end of the limiting member extends from the through hole to the outside;

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figures 1 to 6As shown, this hydraulic pipeline connection assembly of the present invention includes a housing 1, a limiting member 2, a hydraulic pipe 3, and a retaining member 4. The limiting member 2 is hinged in the housing 1 by a first hinge rod 5, and the retaining member 4 is hinged in the housing 1 by a second hinge rod 6. The hydraulic pipe 3 is inserted into the housing 1 and then passes through the housing 1 to maintain its connection with the connecting pipe (not shown in the figure) on the equipment. The inner wall of the connecting pipe cooperates with the outer wall of the hydraulic pipe 3. The limiting member 2 restricts the position of the hydraulic pipe 3, thereby preventing leakage between the connecting pipe and the hydraulic pipe 3.

[0022] The housing 1 has an internal hollowed-out installation area 8, with an opening at the bottom. A symmetrically arranged fixing plate 9 is provided on the housing 1, with fixing holes 10 for securing the housing 1 to the equipment. The front end of the housing 1 has a strip-shaped hole 11, and the rear end has a round hole 12. The hydraulic pipe 3 and the positioning part 13 mate with the strip-shaped hole 11, and the hydraulic pipe 3 mates with the round hole 12. This ensures that the hydraulic pipe 3 can only be inserted into the housing 1 through the strip-shaped hole 11, and then removed from the round hole 12, maintaining the hydraulic pipe 3 in contact with the connecting pipe. This achieves compression and sealing, preventing leakage, and ensures convenient installation without loosening.

[0023] The limiting member 2 is located inside the housing 1. The limiting member 2 is hinged in the installation area 8 by the first hinge rod 5. The housing 1 is provided with a through hole 14 that cooperates with the limiting member 2. The upper end of the limiting member 2 extends from the through hole 14 to the outside.

[0024] The limiting member 2 consists of a pressure end 15 and a limiting end 16. The pressure end 15 is provided with a push plate 17 disposed in the through hole 14. The thickness of the push plate 17 is less than the width of the through hole 14, so that the push plate 17 can move within the through hole 14. The limiting end 16 is inclined and extends downward. The limiting end 16 is provided with a push surface 18, a first limiting inclined surface 19, and a first limiting vertical surface 20. The first limiting inclined surface 19 can not only cooperate with the limiting port 21 for limiting, but also push the limiting member 2 through the positioning part 13 to compress the retaining member 4, so that the retaining member 4 is subjected to force and generates elastic potential energy. By pushing the limiting end 16 through the retaining member 4, the retaining member 4 is forced to be placed in the limiting port 21, preventing the hydraulic pipe 3 from being removed. At the same time, it can also realize the hydraulic pipe 3 being squeezed and connected to the connecting pipe.

[0025] A hydraulic pipe 3 is inserted into the middle of the housing 1. The hydraulic pipe 3 is provided with a positioning part 13 that cooperates with the limiting member 2. The positioning part 13 is provided with a limiting port 21. The limiting port 21 is provided with a second limiting inclined surface 22 that cooperates with the first limiting inclined surface 19 and a second limiting vertical surface 23 that cooperates with the first limiting vertical surface 20.

[0026] The retaining member 4 is symmetrically arranged in the mounting area 8. The retaining member 4 is composed of a spiral segment 24, a first elastic arm 25 and a second elastic arm 26. The first elastic arm 25 contacts the upper inner wall of the mounting area 8, and the second elastic arm 26 contacts the pushing surface 18. A second hinge rod 6 is provided in the middle of the spiral segment 24. The second hinge rod 6 is provided on the housing 1.

[0027] During installation, simply insert the hydraulic pipe 3 into the aligned slot 11 and then remove it from the round hole 12 so that it can mate with the connecting pipe. A sealing ring needs to be installed between the hydraulic pipe 3 and the connecting pipe.

[0028] During removal, simply push the push plate 17, causing it to move the pressure end 15 downwards. This causes the limiting end 16 to rotate upwards, compressing the retaining member 4 and allowing the limiting end 16 to move out of the limiting port 21, thus removing the hydraulic pipe 3. This not only eliminates the need for disassembly tools but also maintains a stable connection of the hydraulic pipe 3, improving disassembly efficiency.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
