[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model provides a car metal pipe that is easy to fix, which includes: a mounting base 1, a mounting flange 2 fixedly connected to the lower surface of the mounting base 1, a fixing hole 3 provided on the mounting flange 2, a slot 18 provided on the mounting base 1, and a pipe body 7 movably connected to the inner surface of the slot 18, specifically a car exhaust pipe.

[0021] Specifically: Mounting base 1 serves as the basic structure of the entire fixing device, providing a platform for the installation and support of other components. The slot 18 on it is used to accurately accommodate the pipe body 7, ensuring the positional accuracy of the pipe body installation and enabling the pipe body to smoothly cooperate with subsequent fixing components. Mounting flange 2 and fixing hole 3 are provided. Mounting flange 2 is fixed to the lower surface of mounting base 1. Through fixing hole 3, bolts and other connectors can be used to firmly install mounting base 1 in the corresponding position on the vehicle, ensuring the stability of the entire fixing device on the vehicle. Pipe body 7 is the object to be fixed and is inserted into slot 18 of mounting base 1. It and the insertion hole 17 on slot 18 provide a position for insertion of pin 14. The fixed connection between pipe body 7 and mounting base 1 is achieved by inserting pin 14 into insertion hole 17.

[0022] The inner wall of the mounting base 1 is fixedly connected with four slide rails 15, and a connecting frame 16 is fixedly connected between the four slide rails 15. The inner surfaces of the four slide rails 15 are slidably connected with pins 14. The tube body 7 and the slot 18 are both provided with insertion holes 17. The pins 14 are movably connected to the insertion holes 17. The inner surface of the connecting frame 16 is rotatably connected with a collar 11. The side surface of the collar 11 is fixedly connected with a guide frame 12. The guide frame 12 is arc-shaped. The upper surface of the pins 14 is fixedly connected with a traction rod 13. The traction rod 13 is slidably connected to the inner surface of the guide frame 12.

[0023] Specifically: The slide rail 15 is installed on the inner wall of the mounting base 1, providing guidance and constraint for the sliding of the pin 14, ensuring that the pin 14 can move smoothly along a specific path, preventing the pin from deviating or wobbling during movement, and ensuring that the pin is accurately inserted into the socket 17. The connecting frame 16 connects the four slide rails 15, which enhances the structural stability and provides rotational support for the collar 11, allowing the collar 11 to rotate flexibly on the inner surface of the connecting frame 16. The pin 14 is the key component for fixing the tube body 7. Guided by the slide rail 15, it slides into the socket 17 on the slot 18, connecting the tube body 7 to the mounting base 1, preventing the tube body 7 from coming out of the slot 18. The collar 11 is rotatably connected to the inner surface of the connecting frame 16. It rotates by being turned by the lever 19. The rotation of the collar 11 causes the guide frame 12, which is fixedly connected to it, to make a circular motion. The guide frame 12 is arc-shaped and fixed to the side surface of the collar 11. When the collar 11 rotates, the guide frame 12 also makes an arc motion. Its special arc shape provides a specific motion trajectory for the traction rod 13. The traction rod 13 is fixed to the upper surface of the pin 14 and slidably connected to the inner surface of the guide frame 12. When the guide frame 12 makes an arc motion, the traction rod 13, under the constraint of the guide frame 12, converts the circular motion of the guide frame 12 into the linear motion of the pin 14, causing the pin 14 to slide on the slide rail 15.

[0024] The mounting base 1 has a sliding groove 4. A lever 19 is fixedly connected to the side surface of the collar 11. The lever 19 is slidably connected inside the sliding groove 4. A protrusion 5 is fixedly connected to the side surface of the mounting base 1. The protrusion 5 is located below the sliding groove 4. A screw hole 6 is provided on the protrusion 5. A screw hole 2 is provided on the lever 19. A screw rod 10 is threadedly connected to the inner surface of the screw hole 2. The screw rod 10 is detachably threadedly connected to the screw hole 6. A knob 8 is fixedly connected to the upper end of the screw rod 10. An anti-slip groove 9 is provided on the knob 8.

[0025] Specifically: the lever 19 is fixed to the side surface of the collar 11 and slides within the groove 4. The operator moves the lever 19 within the groove 4, thereby rotating the collar 11 and controlling the movement of the pin 14. The groove 4 provides a track for the sliding of the lever 19, ensuring the accurate direction of movement of the lever 19. The protrusion 5 is fixed to the side surface of the mounting base 1, located below the groove 4, and has a screw hole 6. The lever 19 has a screw hole 2. When the lever 19 slides to the appropriate position so that the pin 14 is inserted into the socket 17, the screw hole 2 aligns with the screw hole 6. By passing the screw 10 through the screw hole 2 and screwing it into the screw hole 6, the lever 19 can be fixed in the current position, preventing the lever 19 from sliding accidentally, thus ensuring that the pin 14 is always inserted into the socket 17, achieving reliable fixation of the tube body 7. The knob 8 is used to facilitate the user to rotate the screw 10.

[0026] Working principle: In use, first connect the mounting base 1 to the corresponding part of the car through the mounting flange 2 on its lower surface. Using the fixing holes 3 on the mounting flange 2, use bolts or other connectors to firmly fix the mounting base 1 to the car, ensuring the mounting base 1 is in a stable position. Align the tube 7 to be installed with the slot 18 on the mounting base 1, and then insert the tube 7 into the slot 18. At this time, the insertion hole 17 on the tube 7 corresponds to the insertion hole 17 on the slot 18. Move the lever 19 on the mounting base 1. Since the lever 19 is fixedly connected to the collar 11, when the lever 19 slides in the slide groove 4, it drives the collar 11 to rotate on the inner surface of the connecting frame 16. When the collar 11 rotates, the guide frame 12 fixed on its side surface also rotates in a circular motion. The guide frame 12 is arc-shaped, and the traction rod 13 on the pin 14 is slidably connected to the inner surface of the guide frame 12. The circular motion of the guide frame 12 is converted into the linear upward motion of the pin 14 in the slide rail 15 through the traction rod 13. As the pin 14 slides in the slide rail 15, the pin 14 is inserted into the corresponding insertion hole 17 on the tube body 7 and the slot 18, realizing the initial fixation of the tube body 7 and the mounting base 1. When the pin 14 is fully inserted into the insertion hole 17, the screw hole 2 on the lever 19 is aligned with the screw hole 6 on the protrusion 5 on the side surface of the mounting base 1. The screw 10 is screwed into the screw hole 6 through the screw hole 2, so that the lever 19 is fixed in the current position to prevent it from sliding accidentally, thereby ensuring that the pin 14 is always in the state of being inserted into the insertion hole 17, and completing the firm installation of the tube body 7.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
