[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-4 The illustrated automotive water system irregular metal pipe fitting includes a pipe fitting body 1, a hose 2 connected to the end of the pipe fitting body 1, and a fastening component 3 provided between the hose 2 and the pipe fitting body 1. Specifically, the hose 2 is sleeved outside the connecting end of the pipe fitting body 1, the fastening component 3 includes a fastening sleeve 31, the fastening sleeve 31 is sleeved outside the connecting end of the pipe fitting body 1, and the tail of the fastening sleeve 31 is provided with a fixing member 32, the inner side of the head is provided with a sealing fastening component 4, the sealing fastening component 4 is clamped outside the hose 2, and the outer wall of the hose 2 is provided with an adapter groove 21. Specifically, the sealing fastening assembly 4 includes a telescopic stud 41, a sealing fastening clip 42 at the bottom of the telescopic stud 41, a tightening nut 43 on the outside of the telescopic stud 41, and the sealing fastening clips 42 on both sides clamped in the adapter groove 21.

[0018] Specifically, the tail of the fastening sleeve 31 is a fastening tube 311, and the head is a sealing tube 312. The size of the fastening tube 311 is smaller than that of the sealing tube 312. The fastening tube 311 has fastening holes 313 on both the upper and lower sides. The fastening hole 313 is used to install the fixing component 32. The sealing tube 312 has telescopic holes 314 on both the upper and lower sides. The telescopic stud 41 is set in the telescopic hole 314. The internal dimensions of the fastening tube 311 and the sealing tube 312 are both larger than the end dimensions of the pipe fitting body 1.

[0019] Specifically, the fastener 32 includes a fastening post 321 placed in the fastening hole 313, a fastening plate 322 at the bottom of the fastening post 321, a compression spring 323 on the outside of the fastening post 321, the compression spring 323 being placed between the top of the fastening plate 322 and the bottom of the fastening hole 313, and a positioning groove 315 for installing the compression spring 323 at the bottom of the fastening hole 313.

[0020] Specifically, the top outer wall of the fastening column 321 is provided with a limiting ring 324, which is placed on the top of the fastening hole 313. The top of the fastening column 321 is also provided with a pull ring 325, and the bottom of the fastening plate 322 is arc-shaped.

[0021] Specifically, the outer wall of the telescopic stud 41 and the inner wall of the tightening nut 43 are provided with matching threads, the top of the telescopic stud 41 is provided with a limiting plate 44, and the outer wall of the tightening nut 43 is provided with anti-slip texture 45.

[0022] Specifically, the sealing and fastening clamps 42 on both sides are annular in shape, and the size of the adapter groove 21 is larger than the size of the sealing and fastening clamps 42.

[0023] In this embodiment, one end of the hose 2 is directly sleeved over the connecting end of the connector body 1. The sleeve depth is such that the adapter groove 21 on the hose 2 completely covers the end of the connecting end of the connector body 1, ensuring that the adapter groove 21 is located in the outer area of ​​the connecting end of the connector body 1, providing a positioning reference for the subsequent clamping of the sealing fastening assembly 4. Holding the fastening sleeve 31, first align the sealing tube 312 at the head towards the hose 2, and then sleeve the entire fastening sleeve 31 over the connecting end of the connector body 1 and the outside of the hose 2. Push the fastening sleeve 31 until the end of the sealing tube 312 corresponds to the position of the adapter groove 21 on the hose 2. At this time, the fastening tube 311 is located in the root area of ​​the connecting end of the connector body 1, ensuring that the fastening hole 313 corresponds to the position of the outer wall of the connector body 1.

[0024] Specifically, in the initial state, the clamping spring 323 of the fastener 32 is in a naturally extended state, and the fastening plate 322 is pressed against the inner wall of the fastening tube 311 under the action of the spring force. During installation, the fastening column 321 is pulled upward by the pull ring 325, which drives the fastening plate 322 to rise and compress the clamping spring 323 until the bottom of the fastening plate 322 is higher than the outer wall of the pipe fitting body 1. At this time, the position of the fastening sleeve 31 can be freely adjusted. After the position is determined, the pull ring 325 is released, the clamping spring 323 returns to its original position and pushes the fastening plate 322 downward, so that the arc-shaped fastening plate 322 is tightly pressed against the outer wall of the pipe fitting body 1, realizing the initial fixation of the fastening sleeve 31. The limiting ring 324 can prevent the fastening column 321 from falling out of the fastening hole 313 during this process, ensuring the assembly reliability of the fastener 32.

[0025] In this embodiment, the telescopic stud 41 is inserted into the telescopic hole 314 on the outside of the sealing tube 312, so that the bottom sealing clamp 42 is aligned with the adapter groove 21 on the hose 2, and the sealing clamps 42 on both sides are attached to the outer wall of the adapter groove 21 from the top and bottom directions, respectively. Then, the tightening nut 43 is fitted onto the outside of the telescopic stud 41 and tightened. Through the threaded engagement, the telescopic stud 41 moves downward, so that the sealing clamps 42 on both sides gradually clamp the inner wall of the adapter groove 21 until the tightening nut 43 is attached to the outer wall of the sealing tube 312 and can no longer be rotated. At this time, the sealing clamp 42 is completely embedded in the adapter groove 21, realizing the sealing clamping of the hose 2 and the pipe fitting body 1. The limiting plate 44 at the top of the telescopic stud 41 can prevent the tightening nut 43 from falling off the stud, improving the safety of the assembly process.

[0026] In this embodiment, when disassembly or maintenance is required, the tightening nut 43 is first loosened by rotating the anti-slip groove 45 in the opposite direction, causing the telescopic stud 41 to drive the sealing clamp 42 to rise and disengage from the adapter groove 21 of the hose 2; then, the fastening column 321 is pulled upward by the pull ring 325, causing the fastening plate 322 to disengage from the outer wall of the pipe fitting body 1. At this time, the fastening sleeve 31 can be removed from the pipe fitting body 1; finally, the hose 2 can be directly pulled to remove it from the connection end of the pipe fitting body 1. The whole process does not require special tools and is easy to operate.

[0027] In this embodiment, the fastener 32 uses a compression spring 323 to provide continuous elastic pressure. Combined with the fitting design of the arc-shaped fastening plate 322 and the outer wall of the pipe fitting body 1, it can effectively adapt to the vibration environment during vehicle operation and avoid the loosening problem caused by vibration in traditional rigid fasteners. At the same time, the setting of the limiting ring 324 prevents the fastening column 321 from falling off, ensuring the stability of the fixing structure.

[0028] In this embodiment, the sealing and fastening assembly 4 employs an annular sealing and fastening clamp 42 that is embedded in the adapter groove 21 of the hose 2. Compared to the traditional peripheral clamping method, this increases the sealing contact area and provides a tighter fit, effectively preventing coolant leakage in the water system. Furthermore, the clamping force can be finely adjusted according to the actual size of the hose 2 by tightening the thread of the nut 43. The adapter groove 21 is designed to be larger than the sealing and fastening clamp 42, allowing the structure to accommodate hose size errors and improving the product's versatility.

[0029] In this embodiment, the entire assembly process requires no special tools. The fasteners are quickly positioned using the pull ring 325, and manually tightened using the anti-slip grooves 45 of the tightening nut 43. Assembly can be completed by a single person, significantly reducing assembly time compared to traditional pipe fittings. Disassembly is equally simple; components can be separated by reversing the operation, greatly improving the maintenance efficiency of the automotive water system and reducing after-sales maintenance costs.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
