Description
Technical Field
[0001] This utility model relates to the technical field of drop test equipment, and more specifically, to a multi-angle drop test device. Background Technology
[0002] Drop testing plays a crucial role in the research, development, production, and quality inspection of numerous products. Electronic devices, for example, may be accidentally dropped during daily use. If their structural design or protective performance is inadequate, they are easily damaged, impacting user experience and product reputation. If pharmaceutical packaging lacks sufficient drop resistance, drops during transportation and storage can lead to leakage, contamination, or even spoilage, seriously threatening patient safety. In the automotive parts industry, drop testing of certain critical components is essential for vehicle safety under complex road conditions.
[0003] Currently, various drop testing devices exist on the market. For example, the drop testing device disclosed in utility model patent CN222544961U (publication number CN222544961U) and application number CN202420981114.8 includes a sample installation and lifting unit, a sample fixing unit, and a drop receiving unit. It can perform drop tests on products such as point-type heat-sensitive fire detectors and manual fire alarm buttons, allowing for free drop of the tested sample and control of the drop height. It possesses a certain degree of repeatability and consistency, and its operation is relatively simple, improving testing efficiency to some extent. However, this device has significant limitations in adjusting the drop angle, only capable of achieving a limited number of fixed drop angles, making it difficult to simulate the various complex and variable drop angles that products may encounter during actual use or transportation. Utility Model Content
[0004] The purpose of this invention is to provide a multi-angle drop test device to solve the problem mentioned in the background art of the difficulty in simulating the various complex and variable drop angles that products may encounter during actual use or transportation.
[0005] To achieve the above objectives, this utility model provides a multi-angle drop test device, including a base, a lifting rod above the base, both ends of the lifting rod being raised and lowered via vertical adjusting screws, a turntable rotatably connected to the middle of the front side of the lifting rod, a drop guide component installed on the front side of the turntable, and a locking component installed on the front side of the lifting rod near the drop guide component, the end of the locking component being able to lock and position the turntable.
[0006] This base serves as the fundamental support structure for the entire device, providing a stable placement surface. Two vertical adjusting screws are connected to both ends of the lifting rod. By rotating these screws, the rotational motion is converted into the linear lifting motion of the lifting rod, thereby adjusting the drop height. A turntable is mounted on the middle of the lifting rod via a rotatable connection and can rotate around the connection point to change the angle of the drop guide component. The drop guide component is used to place and guide the test specimen in the direction of its fall. The locking component locks the turntable in place after it has rotated to the appropriate angle, preventing it from rotating during the drop test.
[0007] Preferably, the turntable has several slots on the side near the locking component. The locking component includes a locking rod, one end of which is equipped with a spring, and the other end of which can be locked into the corresponding slot.
[0008] This design features a slot on one side of the turntable that engages with a locking lever in the locking mechanism. A spring is installed at one end of the lever, providing elasticity so that the lever remains locked in the slot when no external force is applied. When the turntable angle needs adjustment, external force overcomes the spring force, pulling the lever out of the slot, allowing the turntable to rotate freely. Once the turntable reaches the target angle, the lever is released, and under the spring force, it re-engages into the corresponding slot, securing the turntable.
[0009] Preferably, the slots are arranged in an arc shape with equal spacing, the slots are adapted to the shape of the end of the lever, the front side of the lifting lever is provided with a groove, the other end of the locking component is slidably disposed in the groove, and the end of the spring away from the lever is fixedly connected to the inner wall of the groove.
[0010] This design features several slots arranged in an arc shape at equal intervals, which are adapted to the shape of the end of the clamping rod, allowing for a better fit and more stable clamping effect. The groove on the lifting rod provides a sliding track for the locking components, ensuring that the clamping rod maintains linear movement during sliding and accurately engages and disengages with the slots.
[0011] Preferably, a clamping plate is fixedly installed on the front side of the turntable, which can clamp the drop guide component and lock it in place with bolts.
[0012] This setting involves installing a clamping plate on the front side of the turntable. By placing the drop guide component inside the clamping plate and tightening the bolts, the clamping plate generates a clamping force on the drop guide component, thereby firmly fixing it to the turntable.
[0013] Preferably, the drop guide component includes an angle adjusting cylinder, with a test piece slidably disposed at the top inside the angle adjusting cylinder. The bottom of the test piece is limited by a limiting pin. The inner end of the limiting pin is vertically inserted into the angle adjusting cylinder from one side, and a handle is installed at the outer end of the limiting pin.
[0014] The angle adjustment cylinder is used to hold the test piece. A limiting pin is inserted vertically from one side of the angle adjustment cylinder to limit and support the test piece, preventing it from moving before it falls. The handle at the outer end of the limiting pin allows the operator to insert and remove the limiting pin, enabling quick installation and removal of the test piece.
[0015] Preferably, a rotating shaft is fixedly installed in the middle of the turntable, and the end of the rotating shaft is rotatably connected to the lifting rod.
[0016] This feature involves installing a rotating shaft in the center of the turntable, with its end rotatably connected to the lifting rod. This provides the turntable with a pivot point for rotation, allowing it to rotate freely within a certain range around the shaft and thus adjust the angle.
[0017] Preferably, the top surface of the base is provided with a stress-bearing plate.
[0018] This feature involves placing a force plate on the top surface of the base to directly absorb the impact force generated when the test piece falls, dispersing the impact force to the base and protecting it from damage.
[0019] Preferably, the top surface of the load-bearing plate is provided with anti-slip texture.
[0020] This feature, with its anti-slip texture on the top surface of the stress plate, increases friction between the stress plate and items placed on it (such as auxiliary testing equipment or cushioning materials), preventing these items from slipping when the test piece is dropped and impacted.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] In this multi-angle drop test device, regarding the flexibility of angle adjustment, the front side of the lifting rod is rotatably connected to a turntable. Several slots are opened on one side of the turntable, and a locking component consisting of spring-loaded locking rods enables multi-angle rotation and precise positioning of the turntable. Compared to traditional devices that can only achieve a limited number of fixed-angle drops (such as the patent device in publication number CN222544961U), this device can rotate the turntable to any angle according to actual testing needs, and then lock it by the locking action of the locking rods and slots. This allows the test piece to undergo drop tests at different tilt angles, greatly improving the ability to simulate complex drop angles during actual use or transportation of products.
[0023] In terms of product versatility, the drop guide component's angle adjustment cylinder, limiting pins, and clamping plates mounted on the front side of the turntable allow for flexible fixation of products of different shapes, sizes, and weights. For small, precision products, the limiting pins can be used to support and limit the test piece within the angle adjustment cylinder; for products of different specifications, fixation can be achieved by adjusting the clamping force and range using the clamping plates. This changes the narrow applicability of traditional devices and enables them to be widely used in drop tests of various products such as electronic equipment, pharmaceutical packaging, and automotive parts.
[0024] In terms of experimental accuracy and stability, the stress plate at the top of the base is equipped with anti-slip texture to prevent the device from shifting due to the impact of the test piece falling during the test; the vertical adjustment screw controls the lifting rod to raise and lower, which can accurately adjust the drop height; the turntable and the lifting rod are connected by a rotating shaft, and with the positioning structure of the slot and the rod, the turntable is kept stable at the set angle, avoiding angle deviation during the drop, ensuring the consistency and reliability of the test results, and overcoming the shortcomings of existing devices in terms of drop height adjustment accuracy and overall stability.

[0030] 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.
[0031] This utility model provides a multi-angle drop test device, such as Figure 1As shown, the device includes a base 1, with a lifting rod 3 mounted on top of the base 1. Both ends of the lifting rod 3 are raised and lowered via vertical adjusting screws 2. A turntable 4 is rotatably connected to the center of the front side of the lifting rod 3. A drop guide component 5 is mounted on the front side of the turntable 4. A locking component 6 is mounted on the front side of the lifting rod 3, near the drop guide component 5, and its end can lock and position the turntable 4. The vertical adjusting screw 2 is a screw and slider threaded drive structure.
[0032] In use, the base 1 serves as the basic support structure for the entire device, providing a stable placement surface. The sliders in the two vertical adjusting screws 2 are fixedly connected to both ends of the lifting rod 3. Rotation of the screws 2 converts rotational motion into linear lifting motion of the lifting rod 3, thereby adjusting the drop height. The turntable 4 is rotatably connected to the center of the front side of the lifting rod 3 and can rotate around the connection point to change the angle of the drop guide component 5. The drop guide component 5 is used to place and guide the test piece in the direction of its fall. The locking component 6 locks the turntable 4 in place after it has rotated to the appropriate angle, preventing it from rotating during the drop test. This achieves dual adjustment of drop height and drop angle, simulating product drops at different heights and angles, meeting diverse testing needs. Compared to traditional single-function drop test devices, this significantly improves the comprehensiveness and applicability of the test.
[0033] In this embodiment, as Figure 2 As shown, the turntable 4 has several slots 41 on the side near the locking component 6. The locking component 6 includes a locking rod 61. One end of the locking rod 61 is equipped with a spring 62, and the other end of the locking rod 61 can be locked into the corresponding slot 41.
[0034] In use, a spring 62 is installed at one end of the locking lever 61. The spring 62 provides elasticity, allowing the locking lever 61 to remain locked in the slot 41 when no external force is applied. When it is necessary to adjust the angle of the turntable 4, external force overcomes the elasticity of the spring 62, pulling the end of the locking lever 61 out of the slot 41, allowing the turntable 4 to rotate freely. Once the turntable 4 reaches the target angle, the locking lever 61 is released, and under the action of the spring 62, the end of the locking lever 61 re-engages into the corresponding slot 41, thus fixing the turntable 4. Through a simple and reliable mechanical structure, precise positioning and rapid adjustment of the turntable 4 angle are achieved. The operation is convenient, and compared to some complex angle locking structures, it reduces costs, improves the stability and reliability of the device, and ensures the consistency of the angle in each drop test.
[0035] Specifically, such as Figure 2As shown, several slots 41 are arranged in an arc shape with equal spacing. The slots 41 are adapted to the end shape of the lever 61. A groove 31 is provided on the front side of the lifting rod 3. The other end of the locking component 6 is slidably disposed in the groove 31. The end of the spring 62 away from the lever 61 is fixedly connected to the inner wall of the groove 31.
[0036] In use, the slots 41 are arranged in an arc shape with equal spacing, which matches the shape of the end of the lever 61, allowing for a better fit and more stable clamping effect. The groove 31 on the lifting rod 3 provides a sliding track for the locking component 6, ensuring that the lever 61 maintains linear movement during sliding and accurately engages and disengages with the slots 41. This further enhances the accuracy and stability of the turntable 4's angular positioning. The arc-shaped matching slots 41 and lever 61 structure effectively prevent the lever 61 from loosening or the turntable 4 from shifting due to vibration or other factors during testing. The guiding effect of the groove 31 on the locking component 6 allows operators to operate the lever 61 more easily and accurately, improving the ease of use of the device.
[0037] Furthermore, such as Figure 1 As shown, a clamping plate 7 is fixedly installed on the front side of the turntable 4. The clamping plate 7 has a U-shaped structure and can clamp the drop guide component 5 and lock it in place with bolts. After the drop guide component 5 is placed inside the clamping plate 7 and the bolts are tightened, the clamping plate 7 generates a clamping force on the drop guide component 5, thereby firmly fixing it to the turntable 4. This achieves a detachable fixed connection between the drop guide component 5 and the turntable 4, which facilitates the replacement of different specifications or types of drop guide components 5 according to different test requirements. This increases the versatility and flexibility of the device and can adapt to drop test scenarios for various products.
[0038] Furthermore, such as Figure 3 As shown, the drop guide component 5 includes an angle adjusting cylinder 51. A test piece 53 is slidably disposed at the top inside the angle adjusting cylinder 51. The bottom of the test piece 53 is limited by a limiting pin 52. The inner end of the limiting pin 52 is vertically inserted into the angle adjusting cylinder 51 from one side. A handle is installed on the outer end of the limiting pin 52.
[0039] In use, the angle adjusting cylinder 51 houses the test piece 53. The inner end of the limiting pin 52 supports the bottom of the test piece 53, limiting its movement and preventing it from shifting before the drop. The handle at the outer end of the limiting pin 52 facilitates insertion and removal by the operator, enabling quick installation and removal of the test piece 53. This structure provides a simple and effective way to fix the test piece 53, ensuring it maintains a stable initial position during the drop test and preventing the test piece 53 from shaking or shifting, thus affecting the accuracy of the test results. Furthermore, the handle design makes installation and removal of the test piece 53 more convenient, improving testing efficiency.
[0040] Furthermore, such as Figure 2 As shown, a rotating shaft 42 is fixedly installed in the middle of the turntable 4. The end of the rotating shaft 42 is rotatably connected to the lifting rod 3, providing the axis of rotation for the turntable 4. This allows the turntable 4 to rotate freely around the rotating shaft 42 within a certain range, achieving angle adjustment. This structural design ensures the smoothness and flexibility of the turntable 4's rotation. Compared with other connection methods, the rotating shaft 42 connection can withstand greater torque and weight, ensuring that the turntable 4 can still rotate smoothly when placing test pieces of different weights or performing multi-angle adjustments, providing a reliable structural foundation for accurate angle adjustment.
[0041] Furthermore, such as Figure 1 As shown, a force-bearing plate 11 is provided on the top surface of the base 1 to directly bear the impact force generated when the test piece is dropped, dispersing the impact force to the base 1 and protecting it from damage. This structural design enhances the load-bearing capacity and impact resistance of the base 1, extends the service life of the device, and makes the device more stable during drop tests, reducing device shaking or displacement caused by impact force, thus improving the safety and reliability of the test.
[0042] Furthermore, the top surface of the force plate 11 is provided with anti-slip texture. This texture increases the friction between the force plate 11 and the objects placed on it, preventing these objects from sliding during a drop impact. This structural design further improves the stability of the device during testing, ensuring the safety of the testing environment and the accuracy of the test data, and avoiding interference with test results or safety accidents caused by object slippage.
[0043] When using the multi-angle drop test device of this utility model, first place the device on a flat and stable ground to ensure that the base 1 is in stable contact with the ground. The stress plate 11 and its anti-slip texture on the top surface of the base 1 are used to enhance the stability of the device during the test.
[0044] Based on the shape, size and weight of the test piece 53, select a suitable drop guide component 5, place the drop guide component 5 on the front of the turntable 4, clamp it with the clamping plate 7, and tighten it with bolts to firmly fix the drop guide component 5 on the turntable 4.
[0045] Place the test piece 53 inside the top of the angle adjustment cylinder 51, insert the limiting pin 52 vertically from one side of the angle adjustment cylinder 51, pass it through the bottom of the test piece 53, and use the handle at the outer end of the limiting pin 52 to tighten it, thereby limiting and fixing the test piece 53 to prevent it from moving before falling.
[0046] According to the test requirements, the vertical adjustment screw 2 is rotated. Since the two vertical adjustment screws 2 are respectively connected to the two ends of the lifting rod 3, the rotational motion of the screw 2 is converted into the linear lifting motion of the lifting rod 3, thereby adjusting the height of the lifting rod 3 and thus determining the drop height of the test piece 53.
[0047] When it is necessary to adjust the drop angle, pull the lever 61 in the locking component 6 to overcome the elastic force of the spring 62 and pull the lever 61 out of the slot 41 on one side of the turntable 4. At this time, the turntable 4 can rotate freely around the connection point under the action of the rotating shaft 42.
[0048] Rotate the turntable 4 to the required test angle, release the clamping rod 61, and under the action of the spring 62, the clamping rod 61 will re-clamp into the corresponding arc-shaped equally spaced grooves 41, thereby fixing the turntable 4 and determining the drop angle of the test piece 53.
[0049] After confirming that the height and angle adjustments are complete and all components are securely installed, grasp the handle at the outer end of the limit pin 52, pull out the limit pin 52, so that the test piece 53 loses its limit restraint and falls freely from the angle adjustment cylinder 51 to the force plate 11 at the top of the base 1 under the action of gravity, thus completing a drop test.
[0050] If multiple tests are required or test conditions need to be adjusted, the height and angle can be readjusted according to the above steps, the test piece 53 can be replaced or its fixing method can be adjusted, and the drop test can be carried out again until all test requirements are met.
[0051] Finally, it should be noted that the electronic components in the vertical adjustment screw 2 and other components in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.
[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
