[0002] Carton vibration testing is an important means of assessing the ability of cartons to withstand vibration during transportation, and it is of great significance for ensuring the safety and integrity of products.

[0003] Traditional cardboard box vibration testing requires multiple clamps to fix the cardboard box on the vibration table, and the clamps need to be fixed with multiple bolts. Therefore, in practical applications, users need to adjust the state of the corresponding bolts in turn, which makes the overall operation process relatively complicated and affects its actual use efficiency. To solve the above problems, we propose a test device to simulate the vibration of transported cardboard boxes. Utility Model Content

[0009] Preferably, the square short rod is provided with a limiting block at the end of the inner cavity of the auxiliary screw to maintain a sliding connection with the auxiliary screw.

[0025] 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.

[0026] Please see Figure 1-6A testing device for simulating the vibration of a transported cardboard box includes: a vibrating body 1, an operating box 2 for electrically controlling the vibrating body 1, a first guide rail 3 fixedly installed on the top surface of the vibrating body 1, a second guide rail 4 slidably disposed on the first guide rail 3, a clamping plate 5 for restricting the cardboard box on the vibrating body 1, and a slider 6 slidably connected to the second guide rail 4. The slider 6 is provided with a limit component 7, and the second guide rail 4 is also provided with a linkage component 8. The slider 6 has a U-shaped structure design, and the slider 6 is fixedly connected to the clamping plate 5.

[0027] The limiting component 7 includes a rotating rod 71 rotatably mounted on the slider 6, a square short rod 72 fixedly mounted on the end face of the rotating rod 71, an auxiliary nut 73 fixedly mounted on the inner wall of the slider 6, an auxiliary screw 74 threadedly connected to the auxiliary nut 73 and slidably connected to the square short rod 72, and a friction block 75 fixedly mounted on the end face adjacent to the second guide rail 4 of the auxiliary screw 74. A knob is provided on the end of the rotating rod 71 that passes through the slider 6, and the knob is provided with anti-slip texture. This design can prevent the user from slipping when rotating the rotating rod 71, thereby improving the overall performance of the device. A limiting block is provided on the end of the square short rod 72 located in the inner cavity of the auxiliary screw 74 to maintain the sliding connection with the auxiliary screw 74. This design can prevent the auxiliary screw 74 from separating from the square short rod 72, thereby ensuring the rationality of the overall structural design.

[0028] The linkage assembly 8 includes a first connecting seat 83 fixedly mounted on the side of the second guide rail 4, a second connecting seat 85 fixedly mounted on the side of the first guide rail 3, a first connecting shaft 84 rotatably mounted on the first connecting seat 83, a second connecting shaft 86 rotatably mounted on the second connecting seat 85, a first square long rod 81 fixedly mounted on one end face of the first connecting shaft 84, a first main bevel gear 89 fixedly mounted on the other end face of the first connecting shaft 84, a second square long rod 82 fixedly mounted on the side of the second connecting shaft 86, an auxiliary shaft 87 rotatably mounted on the second guide rail 4, a first secondary bevel gear 88 fixedly mounted on the end of the auxiliary shaft 87 and meshing with the first main bevel gear 89, a disc-shaped shaft 810 and a transmission shaft 812 rotatably mounted inside the slider 6, a second secondary bevel gear 813 fixedly mounted on the end of the transmission shaft 812, and a rotating rod 71 fixedly mounted on the rotating rod 71. The second main bevel gear 814 meshes with the second set of bevel gears 813, and the pulley assembly 811 realizes the transmission connection between the disc shaft 810 and the transmission shaft 812. The slider 6 has a first through hole for the first square rod 81 to pass through. The first square rod 81 is also slidably connected to the disc shaft 810, which can prevent the first square rod 81 from affecting the normal sliding of the slider 6 on the second guide rail 4. The second guide rail 4 has a second through hole for the second square rod 82 to pass through, and the second square rod 82 is located in the cavity inside the second through hole, which can prevent the second square rod 82 from affecting the normal sliding action of the second guide rail 4 on the first guide rail 3. The second square rod 82 is slidably connected to the auxiliary shaft 87, and the second square rod 82 is also slidably connected to the first set of bevel gears 88. There are two second guide rails, and the number of first square rods 81 is the same as the number of second guide rails 4.

[0029] Working principle: A first guide rail 3 is fixed on the vibrating machine body 1, and a second guide rail 4 is slidably connected to the first guide rail 3. Clamping plates 5 slide on the second guide rail 4 via sliders 6 fixedly connected to them. Therefore, the distance between the four clamping plates 5 can be flexibly adjusted to meet the limiting requirements of different sized cartons, thus fixing the cartons onto the vibrating machine body 1. Then, by operating the box body 2 to start the vibrating machine body 1, a test simulating the vibration of transporting cartons can be performed. When actually fixing the position of the clamping plates 5, first rotate the rotating rod 71. The square short rod 72 fixed on the rotating rod 71 is slidably connected to the auxiliary screw 74, which is threadedly connected to the auxiliary nut 73 fixed inside the slider 6. Therefore, after the rotating rod 71 rotates, the auxiliary screw 74 will... The slider 6 is screwed out from inside until the friction block 75 at the end of the auxiliary screw 74 is in close contact with the second guide rail 4, thus restricting the sliding of the slider 6 and the corresponding clamping plate 5. A second main bevel gear 814, meshing with the second set of bevel gears 813, is fixed on the screw rod 71. The drive shaft 812 fixed on the second set of bevel gears 813 is connected to the disc shaft 810 via a pulley set 811. Therefore, after the screw rod 71 rotates, the disc shaft 810 rotates synchronously inside the slider 6. The first square rod 81 is rotatably connected to the first connecting seat 83 fixed on the second guide rail 4 via the first connecting shaft 84. The first square rod 81 and the disc shaft 810 are slidably connected. Both sliders 6 on a single second guide rail 4 are provided with... The through hole is used to pass through the first square rod 81. Therefore, in a single second guide rail 4, after the rotating rod 71 in one slider 6 drives the disc shaft 810 to rotate, the disc shaft 810 in the other slider 6 simultaneously drives the rotating rod 71 to rotate. This causes the two auxiliary screws 74 inside the two sliders 6 in a single second guide rail 4 to simultaneously rotate out from inside the slider 6, so that the two friction blocks 75 simultaneously and tightly contact the second guide rail 4 to lock the positions of the two sliders 6 and the clamping plate 5 on the single second guide rail 4. The first connecting shaft 84 passes through the end of the first connecting seat 83 and is fixed with the first main bevel gear 89, which meshes with the first set of bevel gears 88. The first set of bevel gears 88 is rotatably connected to the second guide rail 4 through the auxiliary shaft 87. Both the bevel gear 88 and the auxiliary shaft 87 are slidably connected to the second square rod 82. The second square rod 82 is also rotatably connected to the second connecting seat 85 fixed on the first guide rail 3 via the second connecting shaft 86. Both second guide rails 4 have through holes for the second square rod 82 to pass through. Therefore, when the rotating rod 71 in a single slider 6 of a single second guide rail 4 drives the disc-shaped shaft 810 to rotate, the first square rod 81 on that second guide rail 4 rotates synchronously. This rotation, in turn, drives the second square rod 82 to rotate via the first main bevel gear 89 and the first secondary bevel gear 88. After the second square rod 82 rotates, the auxiliary shaft 87, the first secondary bevel gear 88, and even the first main bevel gear 89 on the other second guide rail 4 rotate synchronously.Similarly, the first square rod 81 on another second guide rail 4 can drive the rotating rod 71 in the slider 6 to rotate. Then, after a single rotating rod 71 rotates, all the rotating rods 71 ​​in the device rotate synchronously, thereby simultaneously restricting the position of the slider 6 and quickly confining the carton to the vibrating machine body 1.
