Description

Technical Field

[0001] The present application belongs to the field of carton detection technology, and in particular relates to a double-wing drop tester. Background Art

[0002] Carton testing refers to the process of testing and evaluating the various performance indicators of cartons. The purpose is to ensure that the cartons can meet the corresponding quality requirements and effectively protect the products from damage during actual use, such as product packaging, transportation and storage. In order to simulate various falling situations of cartons during product transportation, the corresponding double-wing drop tester will be used.

[0003] The utility model with the existing authorization announcement number CN206974651U discloses a high-speed double-wing drop sensing tester. The lifting platform is installed on the test bench, which is convenient for the lifting platform to drop the test product from a high place to the test bench to observe the different degrees of damage to the test product. The placement table is also provided with a detection light and a swing motor. The detection light improves the detection effect of the test product, and the swing motor exerts a swing force effect. The swing motor is connected to the double-wing plate drive, and the swing motor drives the double-wing plate to swing the test product to the test bench, with good detection effect. The test bench is provided with a sound sensing module, and the test bench is illuminated by the LED light module, which is convenient for users to observe the test product after falling, and is convenient for detection. The sound emitted when the test product falls is sensed by the sound sensing module. When different sounds are emitted, the test product is damaged to different degrees.

[0004] Although the above technical solution has made an upgrade in the detection of the test product, the test bench for the test product is always flat and lacks an adjustment structure that can adjust the inclination angle of the drop table supporting the test product, resulting in a relatively limited drop test scenario for the entire testing machine.

[0005] To this end, we proposed a double-wing drop tester to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that there is a lack of an adjustment structure that can adjust the inclination angle of the drop table that carries the test object, resulting in a relatively limited drop test scenario of the entire test machine, and to propose a double-wing drop test machine.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A double-wing drop tester comprises a base plate, the upper surface of which is fixedly connected to the tester body and the support column, an adjustment support plate is provided above the base plate, the bottom surface of the adjustment support plate and the top of the support column are jointly fixedly connected to a universal joint, two L-shaped plates are fixedly connected to the two side surfaces of the base plate, the inner wall of each of the L-shaped plates is fixedly connected to an electric telescopic rod, the telescopic end of each of the electric telescopic rods is fixedly connected to a connecting plate, the bottom surface of each of the connecting plates is fixedly connected to an upper pull ring, four lower pull rings are fixedly connected to the upper surface of the adjustment support plate, and four pull ropes are provided above the adjustment support plate.

[0009] Preferably, the four electric telescopic rods are electrically connected to the testing machine body through wires, the two ends of each pull rope are respectively mounted on the outer surface of the upper pull ring and the outer surface of the lower pull ring, and the bottom surface of the base plate is fixedly connected to four pads, and the bottom surface of each pad is fixedly connected to a round anti-slip pad.

[0010] Preferably, the front side and the back side of the adjusting support plate are both fixedly connected with brackets, and the inner wall of each bracket is threadedly connected with a tightening bolt.

[0011] Preferably, a top plate is provided inside each of the brackets, a side of each of the top plates close to the bracket is in contact with the inner wall of the bracket, an auxiliary bearing is fixedly connected to the inner wall of each of the top plates, and the inner ring of each of the auxiliary bearings is fixedly connected to the outer surface of the tightening bolt.

[0012] Preferably, the bottom surface of each top plate is fixedly connected with a long anti-skid pad, and the bottom surface of each long anti-skid pad is fixedly connected with a plurality of identical anti-skid protrusions.

[0013] Preferably, the outer surface of each electric telescopic rod is fixedly connected to a reinforcement ring, and the bottom surface of each reinforcement ring is fixedly connected to the upper surface of the L-shaped plate.

[0014] In summary, the technical effects and advantages of this application are:

[0015] Through the mutual cooperation of the base plate, the testing machine body, the support column, the universal joint, the adjustment support plate, the L-shaped plate, the electric telescopic rod, the connecting plate, the upper pull ring, the pull rope and the lower pull ring, the two ends of each pull rope can be flexibly connected to the upper and lower pull rings above and below it. When the testing machine body is controlled, the extension and retraction length of the four electric telescopic rods can be controlled, and the adjustment support plate can be tilted and flipped at multiple angles with the multi-angle rotation of the universal joint. Then, under the mutual extension and retraction of the four electric telescopic rods, the adjustment support plate can be stably flipped and tilted in multiple directions and at multiple angles, so that the test product carried on the testing machine body can fall on the adjustment support plate with different inclination angles, which increases the drop test scenarios of the entire testing machine and avoids the problem that the drop test scenarios of the entire testing machine are relatively limited due to the lack of an adjustment structure that can adjust the inclination angle of the drop table carrying the test product.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6A double-wing drop tester includes a base plate 1, the upper surface of the base plate 1 is fixedly connected with a tester body 2 and a support column 3, the tester body 2 utilizes the existing mature double-wing drop test related electric structure, and can be controlled by an external control structure to perform the corresponding action state, an adjustment support plate 5 is provided above the base plate 1, and four pads 12 are fixedly connected to the bottom surface of the base plate 1, and a round anti-slip pad 13 is fixedly connected to the bottom surface of each pad 12. By providing the pad 12, the base plate 1 can be raised, and then space is left under the base plate 1 for convenient lifting of the entire tester. By providing the round anti-slip pad 13, the anti-slip property of the bottom surface of the pad 12 can be increased, thereby increasing the stability of the entire tester during placement operation.

[0025] The bottom surface of the adjustable support plate 5 and the top of the support column 3 are fixedly connected with a universal joint 4. The universal joint 4 can rotate horizontally, forward and backward, and left and right, so as to provide multi-directional stable support for the adjustable support plate 5. Two L-shaped plates 6 are fixedly connected to the two side surfaces of the bottom plate 1. The front and back surfaces of the adjustable support plate 5 are fixedly connected with brackets 15. The inner wall of each bracket 15 is threadedly connected with a tightening bolt 16. By setting the tightening bolt 16, it can move up and down along the inner wall thread of the bracket 15, and then, in combination with other limiting tightening structures, support plates of different materials placed on the adjustable support plate 5 can be fixed.

[0026] The inner wall of each L-shaped plate 6 is fixedly connected to an electric telescopic rod 7, and the four electric telescopic rods 7 are electrically connected to the testing machine body 2 through wires. The telescopic end of each electric telescopic rod 7 is fixedly connected to a connecting plate 8. A top plate 17 is provided inside each bracket 15, and a side of each top plate 17 close to the bracket 15 is in contact with the inner wall of the bracket 15. The inner wall of each top plate 17 is fixedly connected to an auxiliary bearing 18, and the inner ring of each auxiliary bearing 18 is fixedly connected to the outer surface of the tightening bolt 16. By providing the auxiliary bearing 18, the rotation and lifting movement of the tightening bolt 16 can be decomposed, and the top plate 17 can be moved close to or away from the adjustment support plate 5, thereby facilitating the fixing or disassembly of support plates of different materials placed on the adjustment support plate 5.

[0027] The bottom surface of each connecting plate 8 is fixedly connected to an upper pull ring 9, the upper surface of the adjusting support plate 5 is fixedly connected to four lower pull rings 11, the bottom surface of each top plate 17 is fixedly connected to a long anti-slip pad 19, and the bottom surface of each long anti-slip pad 19 is fixedly connected to several identical anti-slip bosses 20. By setting the anti-slip bosses 20, the anti-slip property of the bottom surface of the long anti-slip pad 19 can be increased. By setting the long anti-slip pad 19 and the anti-slip bosses 20, the anti-slip property of the bottom surface of the top plate 17 can be jointly increased.

[0028] Four pull ropes 10 are arranged above the adjustment support plate 5, and the two ends of each pull rope 10 are respectively mounted on the outer surface of the upper pull ring 9 and the outer surface of the lower pull ring 11. The outer surface of each electric telescopic rod 7 is fixedly connected to a reinforcement ring 14, and the bottom surface of each reinforcement ring 14 is fixedly connected to the upper surface of the L-shaped plate 6. By setting the reinforcement ring 14, the connection between the L-shaped plate 6 and the electric telescopic rod 7 can be strengthened, thereby preventing the two from breaking.

[0029] The working principle of the utility model is as follows: when in use, the test object is placed on the double movable plates of the test machine body 2 in a suitable posture, and then the tilt angle of the support plate 5 is selected and adjusted according to the needs of the simulation scene. When the adjustment support plate 5 needs to be flipped left or right, the external control structure is manipulated and the test machine body 2 is used to control the synchronous extension and contraction length of the two electric telescopic rods 7 on the left and the synchronous extension and contraction length of the two electric telescopic rods 7 on the right. Under the flexible support of the support column 3 and the universal joint 4, the two electric telescopic rods 7 on the left are synchronously extended and the two electric telescopic rods 7 on the right are synchronously shortened, and the adjustment support plate 5 can be tilted to the left lower and the right higher. When the adjustment support plate 5 needs to be flipped forward and backward, the external control structure is manipulated and the test machine body 2 is used to control the synchronous extension and contraction length of the two electric telescopic rods 7 in the front and the two electric telescopic rods in the rear. The telescopic rods 7 are synchronously extended and retracted in length. Under the flexible support of the support column 3 and the universal joint 4, when the two front electric telescopic rods 7 are synchronously extended and the two rear electric telescopic rods 7 are synchronously shortened, the adjustment support plate 5 can be tilted to the side with the front lower and the back higher. Similarly, when the adjustment support plate 5 needs to be tilted to other angles, the four electric telescopic rods 7 cooperate with each other to extend and retract the adjustment support plate 5 to perform stable rollover and tilt in multiple directions and angles, so that the test products carried on the test machine body 2 can fall on the adjustment support plates 5 with different inclination angles, which increases the drop test scenarios of the entire test machine. The design of the entire double-wing drop test machine effectively solves the problem that the drop test scenarios of the entire test machine are relatively limited due to the lack of an adjustment structure that can adjust the inclination angle of the drop table carrying the test products.
