Technical Field
[0001] This utility model belongs to the field of USB flash drive technology and relates to a USB flash drive drop test device. Background Technology
[0002] USB flash drives typically use ABS plastic or metal casings and contain a small printed circuit board inside, allowing them to be small enough to fit in a pocket, like a keychain. After manufacturing, USB flash drives undergo drop tests to assess their physical structural integrity and data storage / reading functionality after experiencing minor drops.
[0003] A drop test device for a USB flash drive disclosed in Chinese patent CN219532443U has a top plate fixed to the top of a lifting plate, a fixing plate fixed to one side of the bottom of the top plate, multiple temporary storage boxes fixed to the side of the fixing plate away from the lifting plate, and a release component provided on the side of the fixing plate close to the lifting plate.
[0004] When using this testing device, the USB flash drive must first be placed into the USB flash drive temporary storage cavity. Then, the USB flash drives to be tested are sequentially removed from the temporary storage frames and placed into different temporary storage boxes. Only then can the release plate release the USB flash drives from the temporary storage boxes. This means that the USB flash drive can only be placed back into the temporary storage box after the test, resulting in low work efficiency.
[0005] A drop tester disclosed in Chinese patent CN217654717U has U-shaped blocks fixedly connected to the front and rear of the outer wall of a disc. Guide posts are slidably inserted on the inner walls of the two U-shaped blocks. A U-shaped plate is fixedly connected to one end of the two guide posts corresponding to the center of the square plate. Springs are slidably sleeved on the outer walls of the two guide posts. The springs are fixedly connected between the U-shaped blocks and the U-shaped plates. A concave block is fixedly connected between the two U-shaped plates.
[0006] When using this testing machine, the test piece must first be inserted between two concave blocks, and then two cylinders are driven to drop the test piece downwards. This means the test piece can only be fixed again after the test, resulting in low work efficiency.
[0007] To address the aforementioned problems, this utility model proposes a drop test device for USB flash drives. Utility Model Content
[0008] To address the problems existing in the background technology, this utility model proposes a drop test device for USB flash drives.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a base plate, a first electric telescopic rod is fixedly connected to the top of the base plate, a fixed shell is fixedly provided at the top of the output end of the first electric telescopic rod, and a plurality of discharge holes are evenly opened at the bottom of the fixed shell;
[0010] The fixed shell is rotatably connected to a rotating column. Several sets of material grooves are evenly opened on the outer surface of the rotating column. Each set of material grooves consists of several placement grooves. The number of placement grooves in each set of material grooves is equal to the number of discharge holes and corresponds one-to-one.
[0011] A collection frame is fixedly connected to the top of the base plate, and the fixing shell is located directly above the collection frame.
[0012] Furthermore, a fixing frame is fixedly connected to the top of the base plate, and a sliding groove that runs vertically through the fixing frame is provided on the fixing frame, with the first electric telescopic rod located at the bottom of the sliding groove;
[0013] A connecting rod is fixedly connected to the outer surface of the fixed shell. The connecting rod is horizontally arranged, and a slide rod is fixedly connected to one end of the connecting rod. The slide rod is slidably connected to the top of the slide groove and is fixedly connected to the top of the output end of the first electric telescopic rod.
[0014] Furthermore, both ends of the rotating column are coaxially fixedly connected to connecting shafts, and both connecting shafts are rotatably connected to the end faces of the corresponding fixed shells. One end of the fixed shell is fixedly connected to a motor, which drives the corresponding connecting shafts to rotate.
[0015] Furthermore, a temporary storage frame is fixedly connected to the top of the fixed shell, and a number of storage holes are evenly arranged on the temporary storage frame. The number of storage holes is equal to the number of discharge holes and they correspond one-to-one.
[0016] Furthermore, a positioning groove is provided on the collection frame, and a test plate is slidably disposed inside the positioning groove.
[0017] Furthermore, the rotating column is provided with an installation groove, which is connected to several discharge holes. A fixed shaft is fixedly connected to the top of the installation groove, and a baffle is rotatably sleeved on the middle of the fixed shaft. The baffle is movably disposed inside the installation groove and on one side of several discharge holes.
[0018] Both ends of the fixed shaft are fitted with torsion springs. One end of the torsion spring is fixedly connected to the baffle, and the other end of the torsion spring is fixedly connected to the inner wall of the mounting groove.
[0019] Furthermore, each of the several placement slots in one of the material troughs is provided with a clearance slot. A second electric telescopic rod is fixedly connected inside each clearance slot. A push plate is fixedly connected to the output end of each second electric telescopic rod. The push plate is slidably connected in the corresponding placement slot. Each push plate abuts against and slides with the baffle.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The drop test device for this USB flash drive is equipped with a rotating column, which is rotatably connected to the inside of the fixed shell. During use, the USB flash drives are placed into the storage holes. The USB flash drive at the bottom will fall into the placement slot. Then, as the rotating column rotates, the USB flash drive will fall onto the next placement slot. After that, the USB flash drive will move to the discharge hole along with the placement slot, allowing it to fall downwards through the discharge hole to complete the drop test. In this way, the rotation of the rotating column can continuously transport the USB flash drives, reducing the number of times the USB flash drives need to be placed and improving work efficiency.
[0022] 2. The drop test device for this USB flash drive is equipped with a baffle. The baffle is rotatably mounted inside the fixed shell. When a set of placement slots equipped with a push plate rotates to the mounting slot, the baffle will block the USB flash drive. At this time, the rotating column stops rotating, and the second electric telescopic rod pushes the USB flash drive to the outside of the placement slot through the push plate, causing the USB flash drive to move to one side of the baffle and push the baffle to rotate, causing the USB flash drive to fall downward from the baffle. This adjusts the angle at which the USB flash drive falls, increases the test range, and makes the test results more accurate. Attached Figure Description

[0029] 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.
[0030] Example 1: As Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: A drop test device for a USB flash drive includes a base plate 1, a first electric telescopic rod 5 fixedly connected to the top of the base plate 1, and a fixed shell 8 fixedly disposed on the top of the output end of the first electric telescopic rod 5. The fixed shell 8 is driven to move vertically up and down by the first electric telescopic rod 5.
[0031] A fixed frame 3 is fixedly connected to the top of the base plate 1, and a through groove 4 is provided on the fixed frame 3. The first electric telescopic rod 5 is located at the bottom of the groove 4.
[0032] A connecting rod 7 is fixedly connected to the outer surface of the fixed housing 8. The connecting rod 7 is horizontally arranged, and a sliding rod 6 is fixedly connected to one end of the connecting rod 7. The sliding rod 6 is slidably connected to the top of the sliding groove 4, and the sliding rod 6 is fixedly connected to the top of the output end of the first electric telescopic rod 5. The sliding rod 6 is positioned by the sliding groove 4, thereby positioning the up and down movement of the fixed housing 8.
[0033] The bottom of the fixed shell 8 is evenly provided with several discharge holes 14. The fixed shell 8 is rotatably connected to a rotating column 11.
[0034] Both ends of the rotating column 11 are coaxially fixedly connected to connecting shafts 12, and both connecting shafts 12 are rotatably connected to the end faces of the corresponding fixed housings 8. A motor 10 is fixedly connected to one end of the fixed housing 8, and the motor 10 drives the corresponding connecting shafts 12 to rotate. The rotating column 11 rotates inside the fixed housing 8 through the connecting shafts 12.
[0035] The outer surface of the rotating column 11 is evenly provided with several sets of material troughs, each set of material troughs consisting of several placement slots 13. The placement slots 13 in each set of material troughs are arranged at intervals on the rotating column 11. The number of placement slots 13 in each set of material troughs is equal to the number of discharge holes 14 and corresponds one-to-one. This ensures that when the rotating column 11 drives the placement slots 13 to rotate, the placement slots 13 in each set of material troughs can rotate to correspond one-to-one with the discharge holes 14 and communicate with each other.
[0036] Each placement slot 13 has two curved chamfers 15 on its two sides that contact the outer surface of the rotating column 11. When the placement slot 13 rotates, the curved chamfers 15 facilitate the ejection of the USB flash drive that falls onto the top of the placement slot 13.
[0037] A temporary storage frame 9 is fixedly connected to the top of the fixed shell 8. Several storage holes 23 are evenly arranged on the temporary storage frame 9. The number of storage holes 23 is equal to the number of discharge holes 14 and they correspond one-to-one vertically. This allows several placement slots 13 in each group of material slots to rotate to correspond one-to-one with the storage holes 23 and to communicate with each other when the rotating column 11 drives the placement slots 13 to rotate.
[0038] A collection frame 2 is fixedly connected to the top of the base plate 1, and a fixing shell 8 is located directly above the collection frame 2. A positioning groove is provided on the collection frame 2, and a test plate 22 is slidably disposed inside the positioning groove. A drop test is conducted by dropping a USB flash drive onto the test plate 22. To simulate whether a USB flash drive will be damaged when dropped onto different types of surfaces, the operator simply needs to remove the test plate 22 and insert test plates of different materials into the collection frame 2.
[0039] Working principle:
[0040] In use, start the motor 10, which drives the rotating column 11 to rotate via the connecting shaft 12. Rotate several placement slots 13 of one set of material troughs until they correspond one-to-one with the storage holes 23 and are interconnected.
[0041] The first electric telescopic rod 5 is activated, and its output end pushes the slide rod 6 to slide up or down inside the slide groove 4. The slide rod 6 drives the connecting rod 7 and the fixed shell 8 to move vertically, thereby adjusting the height of the rotating column 11. This adjusts the height for the drop test.
[0042] When the USB flash drives are placed into the storage holes 23, the USB flash drive at the bottom will fall completely into the corresponding placement slot 13, while a small part of the bottom of the second to last USB flash drive will fall into the top of the placement slot 13.
[0043] Motor 10 drives rotating column 11 to rotate, causing a set of placement slots 13 containing USB flash drives to rotate away from storage hole 23. When placement slots 13 rotate, they will move the internal USB flash drives, and at the same time, they will push a small portion of the second to last USB flash drive that has fallen off upwards through the arc-shaped chamfer 15, so that the second to last USB flash drive moves into storage hole 23.
[0044] As the rotating column 11 continues to rotate, the USB flash drive inside the storage hole 23 will not fall down due to the obstruction of the outer surface of the rotating column 11.
[0045] Similarly, when the placement slots 13 of the next set of material troughs rotate to correspond one-to-one with and communicate with the storage holes 23, USB flash drives will fall into the placement slots 13. Thus, the automatic placement of USB flash drives is achieved by rotating the rotating column 11.
[0046] When the rotating column 11 drives the placement slot 13 containing the USB flash drive to rotate until it connects with the discharge hole 14, the USB flash drive will fall downwards from the discharge hole 14. The USB flash drive falls onto the test plate 22 inside the collection frame 2, thus achieving the purpose of the USB flash drive drop test.
[0047] Example 2: As Figures 4-5 As shown, the difference between this embodiment and Embodiment 1 is that: a mounting groove 16 is provided on the rotating column 11, and the mounting groove 16 communicates with several discharge holes 14. A fixed shaft 17 is fixedly connected to the top of the mounting groove 16, and a baffle 18 is rotatably sleeved on the middle of the fixed shaft 17. The baffle 18 is movably disposed inside the mounting groove 16. The baffle 18 is movably disposed on one side of the several discharge holes 14. The baffle 18 does not obstruct the discharge holes 14.
[0048] Both ends of the fixed shaft 17 are fitted with torsion springs. One end of the torsion spring is fixedly connected to the baffle 18, and the other end of the torsion spring is fixedly connected to the inner wall of the mounting groove 16. In the initial state, the torsion spring drives the baffle 18 to rotate into the interior of the mounting groove 16, so that the baffle 18 blocks the mounting groove 16, and the USB flash drive can only fall out from the discharge hole 14.
[0049] One set of material troughs has several placement slots 13 at their ends, each with a clearance slot 19. A second electric telescopic rod 21 is fixedly connected inside each clearance slot 19. A push plate 20 is fixedly connected to the output end of each second electric telescopic rod 21, and the push plate 20 is slidably connected within the corresponding placement slot 13. Each push plate 20 abuts against and slides against a baffle 18. When the rotating column 11 drives the clearance slot 19 to rotate to the baffle 18, the second electric telescopic rod 21 pushes the baffle 18 through the push plate 20, causing the baffle 18 to rotate.
[0050] Working principle:
[0051] When the motor 10 drives the rotating column 11 to rotate, a USB flash drive will fall onto the top of the push plate 20. When the USB flash drive on the push plate 20 rotates to the baffle 18, the rotating column 11 stops rotating.
[0052] Activate the second electric telescopic rod 21. The output end of the second electric telescopic rod 21 pushes the push plate 20 to slide outward of the placement slot 13, pushing the USB flash drive to move outward of the placement slot 13. The USB flash drive will move onto the baffle 18, and then the push plate 20 will push the baffle 18 to rotate, causing the torsion spring on the fixed shaft 17 to twist.
[0053] When the baffle 18 rotates away from the mounting slot 16, the USB flash drive on one side of the push plate 20 will fall downwards onto the test plate 22. Adjusting the angle at which the USB flash drive falls from the side increases the testing range and makes the test results more accurate.
[0054] After falling, the second electric telescopic rod 21 pulls the push plate 20 into the placement slot 13, at which time the torsion spring will pull the baffle 18 into the mounting slot 16.
[0055] When the placement slot 13 without the push plate 20 rotates to the baffle 18, the baffle 18 will block the USB flash drive, causing the USB flash drive to move to the discharge hole 14 and fall down.
[0056] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
