[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0029] like Figures 1 to 5 As shown, an exhaust pipe testing platform according to one embodiment of this utility model includes a frame 1, on which a first spring 11 is welded. A vibration table 2 is welded to the end of the first spring 11 away from the frame 1. A pair of motors 24 are mounted on the lower plate of the vibration table 2. An eccentric wheel is welded to the rotating shaft of the motors 24. When the vibration table 2 is started, the eccentric wheel rotates with the rotating shaft of the vibration table 2, and the vibration table 2 vibrates, simulating the vibration force experienced by the exhaust pipe during actual operation. The above is prior art and will not be described in detail.
[0030] To fix the exhaust pipe to the vibration table 2, the exhaust pipe testing table also includes a pair of first fixing blocks 3 and a pair of second fixing blocks 4. The first fixing block 3 has a first groove 31, and the second fixing block 4 has a second groove 41 that matches the first groove 31. When the second fixing block 4 is fixed to the first fixing block 3, the first groove 31 and the second groove 41 can clamp the exhaust pipe. A locking component for fixing the second fixing block 4 is installed on the first fixing block 3.
[0031] The locking assembly includes a pair of sleeves 32, which are symmetrically welded to opposite side wings of the first fixing block 3. A second spring 321 is welded to the bottom wall of the sleeve 32, and a sliding post 33 is welded to the end of the second spring 321 away from the sleeve 32. The sliding post 33 is slidably connected inside the sleeve 32. A first rotating post 34 is rotatably connected to the sliding post 33, and a snap-fit plate 341 is integrally formed on the first rotating post 34. The second fixing block 4 has a first through groove 42 and a second through groove 43.
[0032] Specifically, the rigid ends of the exhaust pipe are placed in the first grooves 31 of a pair of first fixing blocks 3, with the flexible tube of the exhaust pipe positioned between the pair of first fixing blocks 3. A second fixing block 4 is taken, and its first through groove 42 and second through groove 43 are aligned with the first rotating post 34 and the snap-fit plate 341, then the second fixing block 4 is placed downwards. At this point, the first rotating post 34 passes through the first through groove 42, and the snap-fit plate 341 is positioned within the second through groove 43. The first rotating post 34 is pulled upwards to expose the snap-fit plate 341 from the second through groove 43. Then, the first rotating post 34 is rotated so that the snap-fit plate 341 and the second through groove 43 are at a 90° angle. The second spring 321 of the first rotating post 34 is released, causing the snap-fit plate 341 to press against the side wing of the second fixing block 4. The second groove 41 then fits tightly against the exhaust pipe, thus securing the exhaust pipe to the first fixing blocks 3 and the second fixing blocks 4. This method is more convenient than tightening bolts and avoids stripping.
[0033] Furthermore, both the first groove 31 and the second groove 41 are provided with anti-slip layers to enhance the fixing effect of the first groove 31 and the second groove 41 on the exhaust pipe and prevent the exhaust pipe from slipping on the first groove 31 and the second groove 41. Preferably, the anti-slip layer is a rubber layer, which can increase the friction between the first groove 31 and the second groove 41 and the exhaust pipe, and also play a buffering role to prevent damage to the surface of the exhaust pipe.
[0034] In order to enable the first rotating column 34 to rotate on the sliding column 33, a rotating groove 331 is provided on the sliding column 33. A second rotating column 343 that matches the rotating groove 331 is integrally formed on the first rotating column 34. A limiting disk 344 is integrally formed on the second rotating column 343. A limiting groove 332 that matches the limiting disk 344 is provided on the sliding column 33.
[0035] Specifically, the second rotating column 343 rotates within the rotating groove 331, and the limiting disk 344 can not only rotate within the limiting groove 332, but also limit the second rotating column 343 to prevent it from detaching from the rotating groove 331.
[0036] Furthermore, the limiting plate 344 is semi-circular, and a third fixing block 333 is integrally formed on the bottom wall of the limiting groove 332. The third fixing block 333 is provided with a first limiting surface 3331 and a second limiting surface 3332. A base 44 is welded onto the second fixing block 4, and a slot 441 is provided on the base 44.
[0037] Specifically, rotating the first rotating column 34 causes the second rotating column 343 and the limiting plate 344 to rotate accordingly. When the limiting plate 344 is in contact with the first limiting surface 3331, the locking plate 341 rotates exactly 90° and is positioned above the locking groove 441. Releasing the second spring 321 of the first rotating column 34 causes it to elastically contract, and the locking plate 341 will lock into the locking groove 441. This effectively limits the first rotating column 34, preventing it from rotating when the vibration table 2 vibrates, and ensuring that the second fixing block 4 and the first fixing block 3 can clamp the exhaust pipe. When the limiting plate 344 is in contact with the second limiting surface 3332, the locking plate 341 and the second through groove 43 overlap, allowing the second fixing block 4 to be easily removed from the first fixing block 3, facilitating the removal and placement of the exhaust pipe after inspection.
[0038] Furthermore, a pull block 342 is integrally formed on the first rotating column 34, and pinching the pull block 342 makes it easy to pull and rotate the first rotating column 34.
[0039] Furthermore, such as Figure 1 and Figure 7As shown, the vibration table 2 has a sliding groove 21, and a pair of sliders 22 are slidably connected in the sliding groove 21. A mounting plate 222 is welded to the sliders 22, and a first fixing block 3 is welded to the mounting plate 222. By sliding the sliders 22, the distance between the pair of first fixing blocks 3 can be changed, which facilitates the testing of exhaust pipes of different lengths.
[0040] Furthermore, bearings 211 are embedded in the opposite walls of the sliding groove 21. A lead screw 23 is welded to the inner ring of a pair of bearings 211. The slider 22 has an internal thread 221 that matches the lead screw 23. The internal threads 221 on the pair of sliders 22 have opposite directions of rotation. The lead screw 23 passes through one end of the side wall of the vibration table 2, and a crank 231 is installed at the end of the lead screw 23 that passes through the vibration table 2.
[0041] Specifically, the screw 23 is rotated by the crank 231. When the screw 23 rotates, a pair of sliders 22 can move closer or further apart. At the same time, the thread engagement force between the screw 23 and the internal thread 221 can lock the pair of sliders 22, preventing the sliders 22 from sliding in the sliding groove 21.
[0042] In use, place the rigid ends of the exhaust pipe into a pair of first grooves 31, with the flexible tube on the exhaust pipe positioned between a pair of first fixing blocks 3. Take a second fixing block 4 and align the first through groove 42 and the second through groove 43 on the second fixing block 4 with the first rotating post 34 and the snap-fit plate 341, then place the second fixing block 4 downwards. At this point, the first rotating post 34 passes through the first through groove 42, the pull block 342 passes through the first rotating post 34, and the snap-fit plate 341 is located in the second through groove 43. Pull the first rotating post 34 upwards with both hands to expose the snap-fit plate 341 from the second through groove 43. Then rotate the first rotating post 34 so that the snap-fit plate 341 is above the snap-fit groove 441. Release the second spring 321 of the first rotating post 34, causing it to elastically contract, and the snap-fit plate 341 will snap into the snap-fit groove 441, allowing the second groove 41 to fit tightly against the exhaust pipe. By using the above method, another second fixing block 4 can be fixed to another first fixing block 3 to complete the fixation of the exhaust pipe. Compared to tightening bolts, it is more convenient to fix and disassemble the exhaust pipe, and there is no risk of stripping the threads.
