[0035] See also Figure 2 and Figure 3 Figure 4 and Figure 5 , Figure 2 It is a partial half-section three-dimensional structure schematic diagram of the utility model; Figure 3 It is a partial three-dimensional structural schematic diagram of the utility model Figure 4 It is a partial three-dimensional structural schematic diagram of the driving and stabilizing frame of the utility model; Figure 5 This is a schematic diagram of the test rod structure of the utility model.

[0036] The driven torsion assembly includes a gear plate 3 and a driven gear 31. The gear plate 3 is fixedly mounted on the top of the supporting motor 2. The output end of the supporting motor 2 passes through the gear plate 3 and is fixedly mounted on the bottom of the supporting plate 1. The output end of the supporting motor 2 rotates with the gear plate 3, and the driven gear 31 meshes with the gear plate 3.

[0037] The gear plate 3 can be fixed while the support plate 1 rotates and drives the driving rod 5 to follow the twisting. During the twisting, the driven gear 31 at the bottom of the driving rod 5 that is meshed with the gear plate 3 is forced to rotate, thereby driving the driving rod 5 to complete the rotation. The rotation of the support plate 1 can rotate all the structures on the top to realize the normal rotation display of the displayed items, and the rotation of the driving rod 5 can drive the structure on the top that is linked with it to have a driving source.

[0038] The clamping assembly is arranged on the liquid crystal display screen 9 and is used to clamp the displayed items; the clamping assembly includes an acrylic plate 91, a clamping strip 92, a sliding clamp block 93 and a tension spring 94. The acrylic plate 91 is detachably mounted on the top of the liquid crystal display screen 9 by bolts, the clamping strip 92 is fixedly mounted on the top of the acrylic plate 91, and the sliding clamp block 93 is symmetrically arranged in two groups, and the sides close to each other are fixedly connected by the tension spring 94, and the bottom of the sliding clamp block 93 is slidably matched with the inside of the clamping strip 92;

[0039] The acrylic plate 91 can be removed from the LCD screen 9 for easy maintenance and replacement, and the transparent structure of the acrylic does not affect the dynamic data display of the LCD screen 9. At the same time, the sliding clamp 93 can slide inside the clamping strip 92 and cooperate with the tension of the tension spring 94 to clamp the object, making it faster to fix.

[0040] The linkage flip control mechanism is arranged at the top of the mounting rod 6 and is used to flip the angle of the liquid crystal display screen 9 to display dynamic data; the linkage flip control mechanism includes a second toggle frame 96, a bevel gear three 97, a driving and stabilizing frame 971, a worm 972, a worm wheel 973, a connecting shaft 974 and a bevel gear four 975, the bevel gear three 97 is key-connected to the surface of the driving rod 5 and is located between the second toggle frame 96, the driving and stabilizing frame 971 is welded and fixed to the top of the mounting rod 6, the worm 972 is rotatably mounted inside the driving and stabilizing frame 971, the worm wheel 973 is fixed on the surface of the connecting shaft 974 and meshes with the worm 972, the connecting shaft 974 is rotatably matched with the driving and stabilizing frame 971, the end of the connecting shaft 974 close to the liquid crystal display screen 9 is fixedly mounted to the liquid crystal display screen 9, the bevel gear four 975 is fixedly mounted on the side of the worm 972 close to the bevel gear three 97, and the bevel gear three 97 is meshed with the bevel gear four 975;

[0041] The second toggle frame 96 can be controlled by the electromagnetic push rod 7. The electromagnetic push rod 7 corresponding to the second toggle frame 96 is started, which can make the second toggle frame 96 drive the bevel gear three 97 and bevel gear four 975 to engage with each other, thereby completing the driving linkage. Subsequently, the rotation of the bevel gear four 975 can drive the worm 972 to rotate, the worm 972 drives the worm wheel 973 to rotate, the worm wheel 973 drives the connecting shaft 974 to rotate, and the connecting shaft 974 drives the LCD screen 9 to flip and display. The meshing of the worm 972 and the worm wheel 973 realizes self-locking to prevent the LCD screen 9 from flipping after losing drive. At the same time, when the meshing is not needed, the second toggle frame 96 is disconnected to move the second toggle frame 96 downward, and the second toggle frame 96 drives the bevel gear three 97 and bevel gear four 975 downward to separate, and no longer performs rotational drive.

[0042] The multiple reciprocating proximity detection mechanism is arranged at the top of the mounting rod 6 and is used to drive the test source to continuously approach the object to be detected; the multiple reciprocating proximity detection mechanism includes a top rod 61, a toggle block 8, an adjusting bolt 81, a torsion block 82, a connecting rod 83, a variety of mounting detection components and a clutch control mechanism, the clutch control mechanism is arranged on the surface of the top rod 61 and is used to control the torsion of the connecting rod 83, the various mounting detection components are arranged on the top rod 61, and are used to mount different test objects to test and display the test objects on the liquid crystal display screen 9, the top rod 61 is fixedly installed on the top of the mounting rod 6, the toggle block 8 is slidably installed on the surface of the torsion block 82, the adjusting bolt 81 is threadedly connected to the inside of the torsion block 82, and one end is limitedly rotated and installed with the toggle block 8, and the two ends of the connecting rod 83 are fixedly installed with the torsion block 82;

[0043] The top rod 61 can be connected to the mounting rod 6 to support the top structure. After the torsion block 82 is driven and twisted by the bevel gear 52, it can drive the toggle block 8 to twist. The toggle block 8 can be twisted to drive the guide cross bar 65 to move upward, so as to drive the test structure away from the display items. When the toggle range of the toggle block 8 needs to be adjusted, the toggle block 8 can be driven by the torsion adjustment bolt 81 to adjust the approach to the torsion block 82 and the distance from the torsion block 82, thereby changing the height of the guide cross bar 65 being lifted.

[0044] The clutch control mechanism includes an electromagnetic push rod 7, a first toggle frame 71, a second locking screw 72, a longitudinal adjustment frame 73, a limiting sleeve frame 74, a bevel gear 1 51 and a bevel gear 2 52. The electromagnetic push rod 7 is provided with two groups, one of which is symmetrically mounted on the outer side of the longitudinal adjustment frame 73, and the output end is fixedly mounted on the first toggle frame 71, and the other group of electromagnetic push rods 7 is symmetrically mounted on the top of both sides of the mounting rod 6, and the output end is fixedly mounted on the second toggle frame 96, the first toggle frame 71 is slidably mounted on the surface of the driving rod 5, the bevel gear 1 51 is keyed to the surface of the driving rod 5 and is located between the first toggle frame 71, the second locking screw 72 is threadedly connected to one side of the longitudinal adjustment frame 73, the limiting sleeve frame 74 is fixedly mounted on the side where the second locking screw 72 is close to each other, and the side where the torsion block 82 is away from each other passes through the limiting sleeve frame 74 and is fixedly mounted on the bevel gear 2 52, and the bevel gear 2 52 is meshed with the bevel gear 1 51;

[0045] When the electromagnetic push rod 7 located on one side of the first toggle frame 71 is started, the first toggle frame 71 can drive the bevel gear 1 51 to engage with the bevel gear 2 52, so that the bevel gear 2 52 can rotate along with the bevel gear 1 51, and because the torsion block 82 is twisted by the drive of the bevel gear 2 52, the toggle block 8 can be synchronously driven to toggle the guide cross bar 65 to move upward, and the guide cross bar 65 can pass upward through the sliding sleeves 62 on both sides to compress the spring 64 with elastic force. When the toggle is completed, the sliding sleeve 62 can be quickly rebounded to the initial position, thereby driving the test rod 651 back to the initial position.

[0046] The various mounted detection components include a sleeve 62, a block 63, a spring 64, a guide cross bar 65, a test rod 651, a first locking screw 652 and a universal threaded hanging rod 653. The sleeve 62 is slidably installed on the top of the top rod 61, the block 63 is fixedly installed on the top of the top rod 61, the spring 64 is sleeved on the surface of the top rod 61 and is located at the top of the sleeve 62, the top of the spring 64 contacts the bottom of the block 63, the guide cross bar 65 is fixed between the two groups of sleeves 62, the test rod 651 is slidably installed on the surface of the guide cross bar 65, the first locking screw 652 is threadedly connected to the top of the test rod 651, and the universal threaded hanging rod 653 is threadedly connected to the bottom of the test rod 651. The sleeve 62 can slide stably on the surface of the top rod 61 to ensure that the two sides of the guide cross bar 65 can be lifted and lowered stably. At the same time, when the guide cross bar 65 is moved, the guide cross bar 65 passes upward through the sleeves 62 on both sides to compress the spring 64. When the movement is completed, the sleeve 62 can be quickly rebounded to the initial position, thereby driving the test rod 651 back to the initial position. This process can achieve an impact effect. This operation can be performed after the universal threaded hanging rod 653 is replaced with an impact block. Since the universal threaded hanging rod 653 can be threadedly installed on the bottom of the test rod 651, the mounting height can also be adjusted, which is convenient for adapting to more universal test pieces, such as cooling fans, heating blocks and sprinkler heads.

[0047] Working principle: when it is necessary to display an item, the item is placed on the clamping strip 92 and clamped by the tension of the tension spring 94 in combination with the sliding clamp block 93 to complete the installation. At the same time, the LCD screen 9 can be connected to dynamic display data through a data line to increase the range of displayed information. The display angle can be activated by the electromagnetic push rod 7 corresponding to the second toggle frame 96, which can drive the second toggle frame 96 to drive the bevel gear three 97 to engage with the bevel gear four 975 upward to complete the driving linkage. Subsequently, the rotation of the bevel gear four 975 can drive the worm 972 to rotate, the worm 972 drives the worm wheel 973 to rotate, the worm wheel 973 drives the connecting shaft 974 to rotate, and the connecting shaft 974 drives the LCD screen 9 to flip and display. The meshing of the rod 972 and the worm gear 973 realizes self-locking, so as to prevent the LCD screen 9 from flipping over after losing the drive. At the same time, when the meshing is not needed, the second toggle frame 96 is disconnected so that the second toggle frame 96 moves downward, and the second toggle frame 96 drives the bevel gear three 97 and the bevel gear four 975 to separate downward, and no longer performs rotational drive. At the same time, the mountings at the bottom of the universal threaded hanging rod 653 are replaced according to the information that the product needs to display, such as a cooling fan, a heating block and a sprinkler head, to test the water resistance, wind resistance, collision resistance and heat resistance of the product, and the acrylic plate 91 is used to prevent the LCD screen 9 from being affected by the test object. When the collision resistance effect needs to be tested, an impact block can be mounted and installed at the bottom of the universal threaded hanging rod 653;

[0048] After the electromagnetic push rod 7 located on one side of the first toggle frame 71 is controlled and started, the first toggle frame 71 can drive the bevel gear 1 51 to mesh with the bevel gear 2 52, so that the bevel gear 2 52 can rotate with the bevel gear 1 51, and the torsion block 82 is twisted due to the driving of the bevel gear 2 52, which can synchronously drive the toggle block 8 to toggle the guide cross bar 65 to move upward, and the guide cross bar 65 passes upward through the sliding sleeves 62 on both sides to compress the spring 64. When the toggle is completed, the sliding sleeve 62 can be quickly rebounded to the initial position, thereby driving the test rod 651 back to the bottom initial position. This process can achieve a collision effect;

[0049] When other effects are needed, they can be achieved by replacing the mounted items. For example, if a fan is mounted, the reciprocating up and down blowing can intuitively show the long-distance and short-distance wind-resistant effects. The remaining mounted items are repeated as shown in the above steps, and the display effect is more intuitive.

[0050] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
