Description

Technical Field

[0001] This utility model belongs to the field of packaging drop test technology, specifically relating to an impact table for drop test of dangerous goods packaging. Background Technology

[0002] The results of drop tests on cargo packaging are an important indicator for assessing the safe transport of packaged goods. Drop tests on dangerous goods packaging are one of the main tests for dangerous goods packaging inspection. Hazardous chemicals refer to those with properties such as toxicity, corrosiveness, explosiveness, flammability, and oxidizing properties. A search revealed that application number "CN202321168905.0" discloses "a railway test impact table for dangerous goods packaging," which describes "using an electric telescopic rod to easily lift the folding plate and drop the goods placed on the support plate onto the drop impact table. Anti-slip protrusions are set to prevent the goods on the support plate from falling during vertical movement, making the goods placed on the support plate more stable." While using an electric telescopic rod to easily lift the folding plate and drop the goods placed on the support plate onto the drop impact table, and using anti-slip protrusions to prevent the goods on the support plate from falling during vertical movement, does indeed make the goods placed on the support plate more stable, the above-mentioned document still has the following problems in actual use:

[0003] In actual use, its drop mechanism is uncontrollable. When the goods are pushed down, the impact surface cannot be controlled, resulting in incomplete detection. Furthermore, its drop mechanism can easily cause the goods to bounce out and injure nearby personnel. The impact platform cannot be replaced. For example, it cannot simulate the impact of goods falling on gravel roads or other road surfaces.

[0004] Based on this, providing a drop surface that can be controlled, prevent goods from popping out, and allow for the replacement of the impact platform to simulate different road surfaces is highly practical. Utility Model Content

[0005] The purpose of this invention is to provide a drop test impact table for dangerous goods packaging, which aims to solve the above-mentioned technical problems.

[0006] This utility model provides a drop test impact table for dangerous goods packaging, including a base, a quick-change assembly, and a test assembly.

[0007] The base has two slots at its top, each slot containing a plug, and the top of each plug is equipped with an impact platform.

[0008] The quick-change assembly includes two fixed plates disposed at one end of the base, a limit rod disposed between the two fixed plates, two movable strips slidably connected to the outer wall of the limit rod, a limit frame disposed at the top of each of the two movable strips, one side of each of the two limit frames being inserted into the impact table, two hinge seats disposed at the other end of the base, a connecting rod hinged to one end of each of the two hinge seats, a locking head disposed at the end of each of the two connecting rods, and the end of each of the two locking heads being inserted into the impact table;

[0009] The test assembly includes a connecting seat located on the top of the base. Inside the connecting seat are two electrically operated telescopic rods. A connecting plate is located on the top of the two electrically operated telescopic rods. A fixing frame is located on the top of the connecting plate. Two support plates are located at one end of the fixing frame. An auxiliary rod is located in the middle of each of the two support plates. Two movable plates are slidably connected to the outer walls of the two auxiliary rods. A clamping plate is located at the bottom of each of the two movable plates.

[0010] In one embodiment of this utility model, an electric cylinder is provided on one side of each of the two support plates, and the output shaft ends of the two electric cylinders are fixedly connected to the moving plate through the support plate.

[0011] In one embodiment of this utility model, a reinforcing rod is provided at the bottom of each of the two support plates, and the ends of the two reinforcing rods are fixedly connected to the connecting plate.

[0012] In one embodiment of this utility model, a support rod is rotatably connected between the two connecting rods, and a torsion spring is provided at the connection between the hinge seat and the connecting rod.

[0013] In one embodiment of this utility model, a bidirectional lead screw nut is rotatably connected to one side of one of the fixed plates, and a rotating head is provided at the end of the bidirectional lead screw nut through another fixed plate. The outer wall of the bidirectional lead screw nut is threadedly connected to two movable bars.

[0014] In one embodiment of this utility model, the outer wall of the base is provided with a plurality of fixing strips, the top of each of the plurality of fixing strips is provided with a baffle plate, the top of the fixing frame is provided with a controller, and an auxiliary groove is provided inside one of the baffle plates.

[0015] In one embodiment of this utility model, both the electric telescopic rod and the electric cylinder are electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The electric telescopic rod allows users to easily open it via a controller, moving it upwards. This, in turn, moves the connecting plate and its top parts upwards, adjusting the distance to the impact table to test the impact damage at different heights. The clamping plate allows users to easily open an electric cylinder via a controller, moving the moving plate and clamping plate to hold the test packaging. The packaging is then released to allow it to fall vertically onto the impact table for the impact test. This clamping and releasing mechanism controls the drop surface, preventing the packaging from popping out of the impact table and injuring nearby personnel, thus achieving accurate and controllable testing.

[0018] 2) The movable strip facilitates quick replacement of the impact table when needed, such as when replacing it with one covered with stones or other materials. The user rotates the rotating head, causing the double-acting screw nut to rotate. The double-acting screw nut, through its external thread and engagement with the limit rod, moves the movable strip towards the center, causing the limit frame to slide out of the impact table and release its restriction. The user then presses the support rod at one end, causing the support rod to move the connecting rod through the hinge seat. This causes the connecting rod to slide the locking head out of the impact table, releasing its restriction. The user can then pull the impact table out of the base via the plug for replacement and fix it in place by resetting other parts, thus achieving quick impact table replacement.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] Example

[0036] Please see Figure 1 - Figure 4 A drop test impact table for dangerous goods packaging includes a base 100, a quick-change assembly 200, and a test assembly 300.

[0037] Please refer to the details. Figure 1 The base 100 has two slots on its top, and plugs 110 are inserted into the interior of each slot. An impact platform 120 is provided on the top of the two plugs 110.

[0038] Please see Figure 2-3The quick-change assembly 200 includes two fixed plates 210 disposed at one end of the base 100. A limit rod 220 is disposed between the two fixed plates 210. Two moving strips 230 are slidably connected to the outer wall of the limit rod 220. A limit frame 240 is disposed at the top of each of the two moving strips 230. One side of each of the two limit frames 240 is inserted and connected to the impact table 120. Two hinge seats 250 are disposed at the other end of the base 100. A connecting rod 260 is hinged to one end of each of the two hinge seats 250. A locking head 270 is disposed at the end of each of the two connecting rods 260. The ends of each of the two locking heads 270 are inserted and connected to the impact table 120.

[0039] In one specific embodiment, the movable strip 230 facilitates easy replacement of the impact table 120 by the user. For example, when replacing the impact table 120 with one covered with stones or other materials, the user rotates the rotating head 800, causing the double-acting screw nut 700 to rotate. The double-acting screw nut 700, through its external thread engagement with the limiting rod 220, moves the movable strip 230 towards the center, causing the movable strip 230 to move the limiting frame 240 from the impact table 120. The impact table 120 slides out from within the base 100, releasing the limit on the impact table 120. At this time, the user presses the support rod 600 to one end, causing the support rod 600 to drive the connecting rod 260 to move through the hinge seat 250. Then, the connecting rod 260 drives the locking head 270 to slide out from within the impact table 120, releasing the limit on the impact table 120. At this time, the user pulls the impact table 120 out from within the base 100 through the plug 110 for replacement, and fixes it by resetting other parts, thereby achieving the purpose of quickly replacing the impact table 120.

[0040] Please see Figure 2 The test assembly 300 includes a connecting seat 310 disposed on the top of the base 100. The connecting seat 310 has two electric telescopic rods 320 disposed inside. The top of the two electric telescopic rods 320 is provided with a connecting plate 330. The top of the connecting plate 330 is provided with a fixing frame 340. One end of the fixing frame 340 is provided with two support plates 350. The middle of each of the two support plates 350 is provided with an auxiliary rod 360. The outer walls of the two auxiliary rods 360 are slidably connected with two movable plates 370. The bottom of each of the two movable plates 370 is provided with a clamping plate 380.

[0041] In one specific embodiment, the electric telescopic rod 320 allows the user to easily open it via a controller, causing it to move upwards. This, in turn, moves the connecting plate 330 and its top parts upwards, adjusting the distance to the impact table 120 to test the impact damage force at different heights. The clamping plate 380 allows the user to easily open the electric cylinder 400 via a controller, causing the moving plate 370 to move and then the clamping plate 380 to clamp the test packaging. The packaging is then released, allowing it to fall vertically onto the impact table 120 for impact testing. This clamping and releasing mechanism controls the drop surface, preventing the packaging from popping out of the impact table 120 and injuring nearby personnel, thus achieving accurate and controllable testing.

[0042] Please see Figure 1 An electric cylinder 400 is provided on one side of each of the two support plates 350, and the output shaft ends of the two electric cylinders 400 pass through the support plate 350 and are fixedly connected to the moving plate 370.

[0043] In one specific embodiment, the provided support plate 350 facilitates the support and fixation of the electric cylinder 400 during use, making the electric cylinder 400 more stable during use and preventing shaking.

[0044] Please see Figure 1 The bottom of each of the two support plates 350 is provided with a reinforcing rod 500, and the ends of the two reinforcing rods 500 are fixedly connected to the connecting plate 330.

[0045] In one specific embodiment, the reinforcement rod 500 is provided to support and reinforce the support plate 350 during use, making the support plate 350 more stable during use and preventing swaying.

[0046] Please see Figure 2 A support rod 600 is rotatably connected between the two connecting rods 260, and a torsion spring is provided at the connection between the hinge seat 250 and the connecting rod 260.

[0047] In one specific embodiment, the torsion spring facilitates reset during subsequent use, allowing the locking head 270 on the connecting rod 260 to re-engage into the impact table 120 for limiting its position and improving stability.

[0048] Please see Figure 3 One of the fixed plates 210 is rotatably connected to a double-acting screw nut 700 on one side. The end of the double-acting screw nut 700 passes through another fixed plate 210 and is provided with a rotating head 800. The outer wall of the double-acting screw nut 700 is threadedly connected to two moving bars 230.

[0049] In one specific embodiment, a rotating head 800 is provided so that the user can rotate the rotating head 800 to drive the bidirectional lead screw nut 700 to rotate, thereby enabling the bidirectional lead screw nut 700 to drive other parts to move.

[0050] Please see Figure 1 The outer wall of the base 100 is provided with several fixing strips 900, and the top of each fixing strip 900 is provided with a baffle plate 1000. The top of the fixing frame 340 is provided with a controller.

[0051] In one specific embodiment, the provided baffle 1000 can prevent the falling test specimen from popping out and injuring nearby people during use, thereby improving safety during use.

[0052] Please see Figure 1 - Figure 4 Both the electric telescopic rod 320 and the electric cylinder 400 are electrically connected to the controller, which is electrically connected to an external power source.

[0053] In one specific embodiment, the provided controller facilitates power control of the electrical equipment during use, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when required.

[0054] In use, the movable bar 230 facilitates easy replacement of the impact table 120, for example, replacing it with one covered with stones or other materials. The user rotates the rotating head 800, causing the double-acting screw nut 700 to rotate. The double-acting screw nut 700, through its external thread engagement with the limiting rod 220, moves the movable bar 230 towards the center, causing the limiting bracket 240 to slide out of the impact table 120, releasing the limitation on the impact table 120. Then, the user presses the support rod 600 to one end, causing the connecting rod 600 to move through the hinge seat 250. This causes the connecting rod 260 to slide the locking head 270 out of the impact table 120, releasing the limitation on the impact table 120. At this point, the user can then remove the impact table 120 from the base 10 via the plug 110. The impact table 120 can be quickly replaced by pulling it out and fixing it with other parts. Then, the electric telescopic rod 320 allows the user to easily open it via a controller, moving it upwards. This, in turn, moves the connecting plate 330 and its top parts upwards, adjusting the distance to the impact table 120 to test the impact damage force at different heights. The clamping plate 380 allows the user to easily open the electric cylinder 400 via a controller, causing the moving plate 370 to move and then the clamping plate 380 to clamp the test packaging. Finally, the packaging is released and dropped vertically onto the impact table 120 for impact testing. The clamping and releasing mechanism controls the drop surface, preventing the packaging from popping out of the impact table 120 and injuring nearby personnel, thus achieving accurate and controllable testing.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
