Description
Technical Field
[0001] The utility model relates to the technical field of automotive pipe fittings, and more specifically, to a hydraulic pipe assembly. Background Art
[0002] A hydraulic oil pipe is a pipe used to transmit hydraulic oil, which is made of high-strength steel or alloy materials. The main function of the hydraulic oil pipe is to transmit the oil pressure pumped out by the hydraulic system to the hydraulic actuating element to perform corresponding control functions. Therefore, it is very important for the hydraulic oil pipe to be usually clean, leak-free, bubble-free, and maintain sufficient strength and toughness to ensure the normal operation of the hydraulic system. In an automobile, the hydraulic oil pipe is mainly applied to parts such as the engine lubrication system, the brake system, and the steering system to ensure the performance and safety of the automobile.
[0003] Based on the above, the inventor found the following problems: Most of the current hydraulic pipes are connected to other pipes through gaskets. When the gasket ages, the sealing performance between the hydraulic pipe and other pipe bodies will decrease, resulting in oil leakage. When the oil leakage is found, the oil has already dripped on the equipment and the hydraulic pipe, thus affecting the service life of the engine and surrounding components.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hydraulic pipe assembly is provided in order to achieve a more practical value purpose. Summary of the Utility Model

[0013] Further, one end of the positioning rod extends to the outside of the fixing seat through the positioning rod, and a pair of limiting blocks are movably inserted inside the end of the positioning rod away from the fixing plate. The bottom ends of the pair of limiting blocks are pressed and fitted against the upper end of the fixing seat.

[0035] Embodiment III
[0036] Refer to Figures 1 - 5As shown in the figure, an installation cavity is provided inside one end of the positioning rod 2014 away from the fixed plate 2013. A pair of sliding rods 2017 are installed inside the installation cavity. A pair of sliders 2018 are slidably connected to the outside of the pair of sliding rods 2017. A pair of second movable seats 2019 are installed at one end of the pair of sliders 2018. A pair of first movable seats 2016 are installed at one end of the limit block 2015 close to the sliding rod 2017. A telescopic rod 2020 is hinged between the first movable seat 2016 and the second movable seat 2019 on the same side through a pin shaft. Springs 2021 are movably sleeved on the outside of both ends of the pair of sliding rods 2017. Both ends of the spring 2021 are fixedly connected to the inner wall of the installation cavity and one side of the slider 2018 respectively. A through hole 1003 is provided inside the top end of the joint 1002, and the joint 1002 is communicated with the inner tube 1004 through the through hole 1003. A sealing gasket 1007 is installed at the upper end of the inner tube 1004. The sealing gasket 1007 is pressed and fitted against the bottom end of the connecting pipe 2001. The upper end of the outer tube 1005 is pressed and fitted against the bottom end of the external sleeve 2002. By providing the first movable seat 2016, when the limit block 2015 is squeezed by the inner wall of the positioning hole 2008 and contracts into the positioning rod 2014, and under the action of the first movable seat 2016, the telescopic rod 2020 is squeezed, so that the telescopic rod 2020 pushes the slider 2018 to move on the sliding rod 2017 under the action of the second movable seat 2019, and the spring 2021 is squeezed. At this time, one end of the telescopic rod 2020 connected to the first movable seat 2016 can contract under the action of the limit block 2015. When one end of the positioning rod 2014 with the limit block 2015 is located outside the fixed seat 2007, after the spring 2021 is no longer squeezed by the sliding rod 2017, the slider 2018 will reset under the action of the spring 2021, so that the limit block 2015 will reset under the connection action of the slider 2018, the second movable seat 2019, the telescopic rod 2020 and the first movable seat 2016, and is located outside the positioning rod 2014 again to fix the position of the bottom plate 2010.
[0037] Specifically, the working principle of this kind of hydraulic pipe assembly is as follows: during use, first place the convex plate 2003 on the connecting pipe 2001 into the groove 1006, which facilitates the alignment between the connecting pipe 2001 and the inner pipe 1004. At this time, the bottom end of the collection box 2005 sleeved outside the external sleeve 2002 is flush with the bottom end of the outer pipe 1005. The user moves the bottom plate 2010 slidably connected to the outside of the inner pipe 1004 upward until it is close to the bottom end of the collection box 2005. At this time, the positioning rods 2014 installed on both sides of the bottom plate 2010 through the fixing plates 2013 are inserted into the positioning holes 2008 inside the fixing seats 2007 on both sides of the collection box 2005. The limiting blocks 2015 are squeezed by the inner wall of the positioning holes 2008 and contract into the inside of the positioning rods 2014, and under the action of the first movable seat 2016, the telescopic rod 2020 is squeezed, so that the telescopic rod 2020 pushes the slider 2018 to move on the slide rod 2017 under the action of the second movable seat 2019, and the spring 2021 is squeezed. At this time, one end of the telescopic rod 2020 connected to the first movable seat 2016 can contract under the action of the limiting block 2015. When the end of the positioning rod 2014 with the limiting block 2015 is located outside the fixing seat 2007, after the spring 2021 is no longer squeezed by the slide rod 2017, the slider 2018 will reset under the action of the spring 2021, so that the limiting block 2015 resets under the connection action of the slider 2018, the second movable seat 2019, the telescopic rod 2020 and the first movable seat 2016, and is re-located outside the positioning rod 2014 to limit the position of the bottom plate 2010. When the bottom plate 2010 is attached to the collection box 2005, turn the bolt 2012 to make the bolt 2012 enter the inside of the threaded groove, thereby completing the installation between the bottom plate 2010 and the collection box 2005. When the gasket 1007 between the inner pipe 1004 and the connecting pipe 2001 ages and causes oil leakage at the connection, it enters the inside of the collection box 2005 through the overflow hole 2004. At the same time, through the oil leakage sensor 2006, the special coating at the sensor detection head absorbs the carbon atoms in the oil and reorganizes the structure, causing the resistance of the induction wire to change, and judging the oil leakage through the resistance change.
