Description

Technical Field

[0001] This application belongs to the technical field of automotive nylon tubing equipment, and particularly relates to a high-temperature resistant double-barrier nylon tubing. Background Technology

[0002] Nylon has high impact strength and excellent comprehensive properties such as abrasion resistance, heat resistance, chemical resistance, lubricity and dyeability. In the automotive industry, nylon is used to make nylon pipes for water transmission.

[0003] Patent CN221300404U discloses a novel high-temperature resistant double-barrier nylon pipe. This utility model includes a nylon main pipe and a heat insulation pipe. The heat insulation pipe includes an EPDM rubber sleeve and an aluminum foil composite glass fiber tube. The EPDM rubber sleeve is slidably sleeved on the outside of the nylon main pipe, and the aluminum foil composite glass fiber tube is fixed on the outside of the EPDM rubber sleeve. The heat insulation pipe includes an upper semi-circular pipe and a lower semi-circular pipe, which are connected by end face snap-fit. The left end of the upper semi-circular pipe and the lower semi-circular pipe are provided with a mating spigot.

[0004] The aforementioned patent uses heat insulation pipes to absorb heat and reduce heat conduction, thereby lowering the internal temperature of the nylon main pipe. However, the installation of heat insulation pipes causes problems when installing the pipes inside the vehicle. Fixing them is difficult and the pipes are prone to rotating and moving out of their designated positions, which ultimately affects the overall vehicle performance and requires improvement. Summary of the Invention

[0005] The purpose of this application is to provide a high-temperature resistant double-barrier nylon tubing that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a high-temperature resistant double-barrier nylon tubing, including a nylon main pipe and a heat-insulating pipe arranged from the inside out, and a fixing mechanism for fixing the nylon main pipe and the heat-insulating pipe to the vehicle body. The fixing mechanism includes:

[0007] The mounting base plate has multiple mounting holes on its surface, and the vehicle body has multiple studs that fit the mounting holes.

[0008] A fixing component is mounted on the mounting base plate and used to wrap the nylon main pipe and the heat insulation pipe, and the fixing component is fixedly connected to the mounting base plate;

[0009] The mounting hole and the stud are fixed together by a nut.

[0010] The aforementioned high-temperature resistant double-barrier nylon tubing provides high-temperature resistance through the insulated tubing. The mounting base mates with studs on the vehicle body, and a stable connection is formed by tightening nuts. This not only improves the overall stability of the piping system but also effectively prevents vibration and displacement during vehicle operation. Furthermore, the multiple mounting holes corresponding to the vehicle body studs standardize and simplify the installation process. Installers simply align the mounting base with the studs and secure it with nuts, reducing installation time and improving work efficiency. The studs can be welded to the vehicle body, and their position can be adjusted during welding according to installation requirements.

[0011] In addition, the fixing components can also secure the nylon main pipe and the insulation pipe, preventing the nylon main pipe from rotating or falling out of its designated position, thus reducing the potential risk of failure caused by pipe loosening or displacement.

[0012] Furthermore, the fixing component includes:

[0013] The sleeve consists of a tube body, an adjustment groove on the tube body, and mating structures on both sides of the adjustment groove. The adjustment groove runs through the tube body, and the sleeve is made of an elastic material.

[0014] The connector is located at the bottom of the sleeve;

[0015] The connecting seat and the mounting base are integrally formed and bent, and the connecting seat and the sleeve are connected by welding.

[0016] The pipe body is responsible for wrapping and securing the nylon main pipe and insulation pipe. Its size and shape are adapted to the outer diameter of the installed nylon main pipe and insulation pipe to ensure a tight fit and effective fixation. An adjustment groove is formed on the pipe body, extending along the pipe's axis and running through the entire groove. The sleeve can be pried open along the adjustment groove when needed, facilitating the installation of the nylon main pipe and insulation pipe into the sleeve, thus simplifying the installation process and improving work efficiency.

[0017] After the sleeve is opened and the pipeline is installed, the sleeve can automatically return to its original position and maintain a tight wrapping state. The installation of the mating structure can then secure the sleeve, preventing it from loosening due to external forces; this may be achieved through a convex-concave snap-fit ​​mechanism. Simultaneously, the connector is installed at the bottom of the sleeve, integrally formed with the mounting plate and bent in shape, enhancing the connection strength between the sleeve and the mounting plate, and making the entire fixing assembly more compact and stable. The connector and sleeve are connected by welding, ensuring the stability of the entire fixing assembly.

[0018] Furthermore: the mating structure includes:

[0019] The first mounting ear is provided on the sleeve and located on one side of the adjustment groove;

[0020] The second mounting ear is provided on the sleeve and located on the other side of the adjustment groove;

[0021] Fastening bolts are used to connect the first mounting ear and the second mounting ear. The first mounting ear and the second mounting ear are respectively provided with a first through hole and a second through hole for the fastening bolt to pass through.

[0022] The bottom of the second mounting ear is also provided with a fastening nut that is compatible with the fastening bolt.

[0023] The first and second mounting ears are respectively provided on the sleeve and located on both sides of the adjusting groove, providing connection points so that the sleeve can be re-secured after the installation pipeline is pried open using fastening bolts. The first and second mounting ears each have a first through hole and a second through hole, respectively. Fastening bolts are inserted into the two through holes sequentially and secured with fastening nuts, thus ensuring the sleeve's effective fixation to the nylon main pipe. Simultaneously, the threaded engagement between the fastening nut and the fastening bolt provides good tightening force and anti-loosening effect, ensuring that the sleeve will not loosen due to vibration or external forces during vehicle operation.

[0024] Furthermore, a first mounting groove and a second mounting groove are respectively provided in the first through hole and the second through hole. The first mounting groove and the second mounting groove are connected and spliced ​​to form an expansion groove. A spring is provided in the expansion groove. The spring is sleeved on the fastening bolt, and a pressure ring that contacts the spring is provided on the fastening bolt.

[0025] The first mounting groove is located at the bottom of the first through hole, and the second mounting groove is located at the top of the second through hole. These two grooves cooperate to form an expansion groove for the spring's extension and retraction, ensuring the spring is properly fitted onto the fastening bolt. Simultaneously, the spring has a pressure ring that contacts it. When the spring is fitted onto the fastening bolt, the spring is compressed, generating a preload, thus making the first and second mounting ears more securely fastened. This effectively prevents the sleeve from loosening due to vibration or external force, ensuring the safety and durability of the nylon main pipe and heat insulation pipe during vehicle operation. The fastening bolt and pressure ring are detachably connected.

[0026] Furthermore, multiple protrusions and grooves are provided on both sides of the adjustment groove, with the grooves and protrusions interlocking and fitting together, and both the protrusions and grooves are mounted on the sleeve.

[0027] The protrusions and grooves are installed on both sides of the adjustment groove and on the sleeve, respectively, to provide guidance and positioning when the sleeve is reset. The protrusions and grooves can be inserted into each other to prevent the sleeve from being misaligned or loosened when subjected to external force.

[0028] Furthermore, multiple reinforcing ribs are provided at the bend between the connecting seat and the mounting base plate.

[0029] By installing reinforcing ribs at the bend between the connector and the mounting base, stress concentration caused by bending can be effectively resisted, preventing breakage or deformation of the connector and mounting base at that point. This also makes the connection between the connector and the mounting base more stable.

[0030] The beneficial effects of this application are:

[0031] 1. By mounting the base plate and engaging the studs on the vehicle body, and then tightening it with nuts to form a stable connection, not only is the overall stability of the piping system improved, but the vibration and displacement of the piping during vehicle operation are also effectively prevented.

[0032] 2. The fixing components can also fix the nylon main pipe and the insulation pipe, preventing the nylon main pipe from rotating and falling out of the specified position, thus reducing the potential risk of failure caused by pipe loosening or displacement.

[0033] 3. When tightening the fastening bolts, the spring is compressed, generating preload, which makes the first and second mounting ears more secure, effectively preventing the sleeve from loosening due to vibration or external force, and ensuring the safety and durability of the nylon main pipe and heat insulation pipe during vehicle operation.

[0042] The high-temperature resistant double-barrier nylon tubing provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0043] Example 1:

[0044] like Figures 1 to 4 As shown, this application embodiment provides a high-temperature resistant double-barrier nylon tubing, including a nylon main pipe 100 and a heat insulation pipe 110 arranged from the inside out, and also includes a fixing mechanism for fixing the nylon main pipe 100 and the heat insulation pipe 110 to the vehicle body. The fixing mechanism includes:

[0045] The mounting base plate 200 has multiple mounting holes 210 on its surface, and multiple studs 220 that are adapted to the mounting holes 210 are provided on the vehicle body.

[0046] The fixing component 300 is disposed on the mounting base plate 200 and is used to wrap the nylon main pipe 100 and the heat insulation pipe 110, and the fixing component 300 is fixedly connected to the mounting base plate 200.

[0047] The mounting hole 210 and the stud 220 are fixed together by a nut.

[0048] In some embodiments of this application, such as Figure 1As shown, the high-temperature resistant double-barrier nylon tubing described above utilizes the heat insulation tube 110 to provide high-temperature resistance. The mounting base 200 mates with the studs 220 on the vehicle body, and a stable connection is formed by tightening nuts. This not only improves the overall stability of the piping system but also effectively prevents vibration and displacement of the piping during vehicle operation. Furthermore, the correspondence between multiple mounting holes 210 and the studs 220 on the vehicle body makes the installation process more standardized and convenient. Installers only need to align the mounting base 200 with the studs 220 and secure it with nuts, shortening installation time and improving work efficiency. The studs 220 can be welded to the vehicle body, and their position can be adjusted during welding according to installation requirements.

[0049] In addition, the fixing component 300 can also fix the nylon main pipe 100 and the heat insulation pipe 110, preventing the nylon main pipe 100 from rotating and falling out of the designated position, thus reducing the potential risk of failure caused by pipe loosening or displacement.

[0053] The sleeve 310 consists of a tube body 311, an adjustment groove 312 disposed on the tube body 311, and a mating structure 400 disposed on both sides of the adjustment groove 312. The adjustment groove 312 penetrates the tube body 311, and the sleeve 310 is made of an elastic material.

[0054] Connector 320 is located at the bottom of sleeve 310;

[0055] The connecting seat 320 and the mounting base plate 200 are integrally formed and bent, and the connecting seat 320 and the sleeve 310 are connected by welding.

[0056] In this embodiment, the tube body 311 is responsible for wrapping and fixing the nylon main tube 100 and the heat insulation tube 110. Its size and shape are adapted to the outer diameter of the installed nylon main tube 100 and heat insulation tube 110 to ensure a tight fit and effective fixation. The adjustment groove 312 is formed on the tube body 311 and extends along the axial direction of the tube body 311 and passes through the entire groove. When needed, the sleeve 310 can be opened along the adjustment groove 312, thereby facilitating the installation of the nylon main tube 100 and the heat insulation tube 110 into the sleeve 310, thus simplifying the installation process and improving work efficiency.

[0057] After the sleeve 310 is opened and the pipeline is installed, the sleeve 310 can automatically return to its original position and maintain a tight wrapping state. The installation of the cooperating structure 400 can fix the sleeve 310, preventing it from loosening due to external forces, possibly through a convex-concave snap-fit ​​mechanism. Simultaneously, the connecting seat 320 is installed at the bottom of the sleeve 310, integrally formed with the mounting base plate 200 and bent, enhancing the connection strength between the sleeve 310 and the mounting base plate 200, and making the entire fixing assembly 300 more compact and stable. The connecting seat 320 and the sleeve 310 are connected by welding, ensuring the stability of the entire fixing assembly 300.

[0058] Furthermore, multiple protrusions 500 and grooves 510 are respectively provided on both sides of the adjusting groove 312. The grooves 510 are inserted into the protrusions 500, and both the protrusions 500 and the grooves 510 are installed on the sleeve 310.

[0059] The protrusion 500 and the groove 510 are respectively installed on both sides of the adjusting groove 312 and are both installed on the sleeve 310. They are used to provide guidance and positioning when the sleeve 310 is reset. The protrusion 500 and the groove 510 can be inserted into each other to prevent the sleeve 310 from being misaligned or loosened when subjected to external force.

[0061] This application provides a high-temperature resistant double-barrier nylon tubing. In addition to the above-mentioned technical features, the high-temperature resistant double-barrier nylon tubing of this application also includes the following technical features.

[0062] like Figure 1 , Figure 4 and Figure 5 As shown, the mating structure 400 includes:

[0063] The first mounting ear 410 is disposed on the sleeve 310 and located on one side of the adjustment groove 312;

[0064] The second mounting ear 420 is disposed on the sleeve 310 and located on the other side of the adjustment groove 312;

[0065] Fastening bolt 430 is used to connect the first mounting ear 410 and the second mounting ear 420. The first mounting ear 410 and the second mounting ear 420 are respectively provided with a first through hole 440 and a second through hole 450 for the fastening bolt 430 to pass through.

[0066] The bottom of the second mounting ear 420 is also provided with a fastening nut that is compatible with the fastening bolt 430.

[0067] In this embodiment, the first mounting ear 410 and the second mounting ear 420 are respectively disposed on the sleeve 310 and located on both sides of the adjusting groove 312, providing connection points so that the sleeve 310 can be re-fixed after the installation pipeline is pried open by the fastening bolt 430. The first mounting ear 410 and the second mounting ear 420 are respectively provided with a first through hole 440 and a second through hole 450. The fastening bolt 430 is inserted into the two through holes in sequence and fixed with the fastening nut, thereby ensuring the fixing effect of the sleeve 310 on the nylon main pipe 100. At the same time, the threaded engagement between the fastening nut and the fastening bolt 430 provides good fastening force and anti-loosening effect, ensuring that the sleeve 310 will not loosen due to vibration or external force during vehicle operation.

[0068] Furthermore, a first mounting groove 461 and a second mounting groove 462 are respectively provided in the first through hole 440 and the second through hole 450. The first mounting groove 461 and the second mounting groove 462 are connected and spliced ​​to form an expansion groove 460. A spring 470 is provided in the expansion groove 460. The spring 470 is sleeved on the fastening bolt 430, and the fastening bolt 430 is provided with a pressure ring 480 that contacts the spring 470.

[0069] The first mounting groove 461 is formed at the bottom of the first through hole 440, and the second mounting groove 462 is formed at the top of the second through hole 450.

At the same time, the spring 470 is provided with a pressure ring 480 that contacts the spring 470. When the spring 470 is fitted onto the fastening bolt 430, the spring 470 is compressed, generating a preload, which makes the fastening of the first mounting ear 410 and the second mounting ear 420 more secure. This effectively prevents the sleeve 310 from loosening due to vibration or external force, ensuring the safety and durability of the nylon main tube 100 and the heat insulation tube 110 during vehicle operation. In addition, the pressure ring 480 and the fastening bolt 430 are detachably connected.
