Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model provides a pipe fitting device, including a first fixing plate 1 and a second fixing plate 2. The first fixing plate 1 and the second fixing plate 2 can surround the pipe. Each of the first fixing plate 1 and the second fixing plate 2 is provided in a set. A connecting component is provided between the two first fixing plates 1 and the second fixing plate 2. The connecting component includes a sliding cylinder 9 and a sliding rod 10. An mounting plate 8 is fixedly connected to both the first fixing plate 1 and the second fixing plate 2. The sliding cylinder 9 and the sliding rod 10 are fixedly connected to the mounting plate 8 between the first fixing plate 1 and the second fixing plate 2, respectively. A fixing groove 22 is opened on the inner wall of the sliding cylinder 9. A cover 11 is screwed to the end of the sliding cylinder 9 away from the mounting plate 8. The sliding rod 10 is slidably sleeved inside the sliding cylinder 9. A fixing mechanism is provided on the sliding rod 10. The fixing mechanism includes an electric push rod 12. The fixed end of the electric push rod 12 is fixedly connected to the inner wall of the slide rod 10. The movable end of the electric push rod 12 is fixedly connected to a first step block 13. The front end of the slide rod 10 is provided with a second step block 14 symmetrically distributed vertically. Each of the second step blocks 14 is fixedly connected to a connecting post 15 on the opposite side. The connecting post 15 extends into the interior of the slide cylinder 9 and is fixedly connected to a movable plate 16. The outer wall of the movable plate 16 is provided with a protrusion 17, which is adapted to the fixing groove 22.
[0017] The first step block 13 has inclined surfaces on both the top and bottom, and the two second step blocks 14 on the slide rod 10 are respectively matched with the inclined surfaces on the top and bottom of the first step block 13.
[0018] A first limiting ring 23 and a second limiting ring 24 are fixedly connected to the outer surface of the slide rod 10. One side of the first limiting ring 23 is in contact with one side of the moving plate 16, and one side of the second limiting ring 24 is in contact with the other side of the moving plate 16. The outer wall of the moving plate 16 is adapted to the inner wall of the slide cylinder 9, and the inner wall of the moving plate 16 is adapted to the outer wall of the slide rod 10.
[0019] Specifically, the first fixing plate 1 and the second fixing plate 2 need to be fixed to the two pipe sections respectively. The slide rod 10 can slide inside the slide cylinder 9. When adjusting the gap between the two pipe sections, one of the pipe sections can be moved directly. After the gap is adjusted, the electric push rod 12 can be activated to drive the first step block 13 to move. The electric push rod 12 is powered by the built-in power supply of the slide rod 10. The slide rod 10 has a storage compartment for the power supply inside. When the first step block 13 moves, its inclined surface will contact the inclined surface of the second step block 14. The second step block 14 can be squeezed to move it. When the second step block 14 moves, it can drive the moving plate 16 to move through the connecting column 15. The first limiting ring 23 and the second limiting ring 24 provide a limiting effect for the moving plate 16, so that the moving plate 16 can accurately fit against the inner wall of the slide cylinder 9, which improves the stability of the moving plate 16 when it moves. When the moving plate 16 fits against the inner wall of the slide cylinder 9, the protrusion 17 will be stuck in the corresponding fixing groove 22 to lock the slide rod 10, thereby ensuring the stability of the two pipe sections during welding.
[0020] Furthermore, in order for the movable plate 16 to be reset, such as Figure 4 , Figure 5 and Figure 6 As shown, a sliding column 18 is fixedly connected to the inner wall of the sliding rod 10, and a connecting plate 19 is slidably connected to the outside of the sliding column 18. One side of the connecting plate 19 is fixedly connected to one side of the second step block 14. A fixing ring 20 is fixedly sleeved on the outside of the sliding column 18, and a spring 21 is sleeved on the outside of the sliding column 18. One end of the spring 21 is fixedly connected to one side of the fixing ring 20, and the other end of the spring 21 is fixedly connected to one side of the connecting plate 19.
[0021] When the second step block 14 moves the moving plate 16 via the connecting column 15, the connecting plate 19 also slides on the side surface of the sliding column 18, simultaneously stretching the spring 21. When the operator adjusts the gap between the two pipe sections, they need to control the electric push rod 12 to reset the first step block 13. When the second step block 14 loses the pressure of the first step block 13, the spring 21 will reset the connecting plate 19. When the connecting plate 19 resets, it can pull the second step block 14, thereby resetting the moving plate 16, thus releasing the locking state of the sliding rod 10, so that the operator can adjust the gap between the two pipe sections.
[0022] Furthermore, in order to improve the stability of the slide bar 10 during movement, such as Figure 3 and Figure 4 As shown, a sealing block 25 is fixedly connected to one end of the slide rod 10 inside the slide cylinder 9. A limiting strip 26 is fixedly connected to the side surface of the sealing block 25. A limiting groove 27 is opened in the inner wall of the slide cylinder 9. The side surface of the sealing block 25 slides in cooperation with the inner wall of the slide cylinder 9. The limiting strip 26 is inserted into the inside of the limiting groove 27.
[0023] The limiting groove 27 and the limiting strip 26 provide a guiding effect for the slide bar 10, enabling the slide bar 10 to move along a preset trajectory, reducing the possibility of the slide bar 10 deviating, and improving the stability of the slide bar 10 when moving.
[0024] In order for the first fixing plate 1 and the second fixing plate 2 to be fixed to the pipe, such as Figure 1 and Figure 2 As shown, rubber pads 7 are fixedly connected inside the first fixing plate 1 and the second fixing plate 2. A first fixing strip 3 is fixedly connected to the outer wall of the first fixing plate 1. A first connecting seat 5 is fixedly connected to both ends of the first fixing strip 3. A second fixing strip 4 is fixedly connected to the outer wall of the second fixing plate 2. A second connecting seat 6 is fixedly connected to both ends of the second fixing strip 4. The second connecting seat 6 and the first connecting seat 5 are fixedly connected by bolts and nuts.
[0025] After the first fixing plate 1 and the second fixing plate 2 are spliced on the pipe, the first fixing strip 3 and the second fixing strip 4 need to be aligned. Then, bolts can be used to pass through the first connecting seat 5 and the second connecting seat 6, and nuts can be used to tighten them, so that the first fixing plate 1 and the second fixing plate 2 can be fixed to the pipe. The rubber pad 7 can play a buffering role and increase friction, thereby improving the stability of the first fixing plate 1 and the second fixing plate 2 after being connected to the pipe.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
