Description

Technical Field

[0001] This utility model relates to the field of vibration table technology, specifically a vibrating table surface structure that can be flipped and folded. Background Technology

[0002] An electric vibration table is a testing device specifically designed for reliability environmental testing. It is widely used in industries such as defense, aviation, aerospace, communications, and automobiles. When conducting reliability tests, electric vibration tables mainly include two vibration modes: vertical vibration and horizontal vibration. Existing electric vibration tables usually only have one vibration table surface. When the tested object is large or there are many objects, the small table surface area will cause many inconveniences.

[0003] In response to this situation, some existing technologies have developed vibration tables with large tabletop areas. However, the excessive size of the tabletop makes the vibration tabletop take up a lot of space, which is not conducive to transportation and storage. Therefore, we provide a vibrating tabletop structure that can be flipped and folded to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a reversible and foldable vibration table platform structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable and reversible vibration table structure includes a main table mounted on a frame. The two ends of the main table are respectively provided with a first side table via a hinge assembly. The first side table has a slot inside, and a second side table is slidably engaged inside the slot.

[0007] The hinge assembly includes a hinge hole on the main table surface and a hinge rod on the bottom of the first side table surface, with both ends of the hinge rod being movably inserted into the hinge hole.

[0008] The frame is equipped with a flipping mechanism, which can drive the first side table to flip 90°.

[0009] The hinge rod and the second side platform are connected by a linkage structure. When the first side platform is flipped, it will drive the hinge rod to rotate. When the hinge rod rotates, it can drive the second side platform to slide to the left or right inside the slot.

[0010] As described above, a foldable and reversible vibration table structure includes a first lead screw rotatably mounted on a frame, an adjusting block threaded onto the first lead screw, a support arm between the adjusting block and the first side table, and the two ends of the support arm being hinged to the adjusting block and the first side table, respectively.

[0011] As described above, a foldable and reversible vibration table structure is provided: a motor is fixedly mounted on the frame, and the output end of the motor is connected to a first lead screw via a coupling.

[0012] As described above, a foldable and reversible vibration table structure is provided: a limit rod is fixed on the frame, a limit hole is provided on the adjusting block, and the limit rod is inserted through the limit hole.

[0013] As described above, a foldable and reversible vibration table structure includes a sliding groove at the bottom of a first side table, in which a slider fixed to the bottom of a second side table is slidably engaged. A second lead screw is rotatably mounted at the bottom of the first side table, and a threaded sleeve fixed to the slider is threadedly connected to the second lead screw. The second lead screw and a hinge rod are connected by a transmission mechanism, and the rotation of the hinge rod will drive the second lead screw to rotate.

[0014] As described above, a foldable and reversible vibration table structure includes a transmission mechanism comprising a driving bevel gear mounted on a hinge rod and a driven bevel gear mounted on a second lead screw, wherein the driving bevel gear and the driven bevel gear are meshed together.

[0015] As described above, a reversible and foldable vibration table platform structure is provided: one end of the second lead screw is fixed with a stop block to prevent the threaded sleeve from slipping off.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by rotating and hinged the first side table at both ends of the main table, and movably engaging the second side table inside the first side table, the area of ​​the main table is expanded by the first side table and the second side table, thereby effectively increasing the overall area of ​​the vibration table, so as to meet the vibration table testing conditions when the tested item is large or there are many items placed on it.

[0017] This utility model features a flipping mechanism on its frame, which drives the first side table to automatically flip 90°. After use, the first side table can be folded and stored by flipping it to a vertical position. Simultaneously, the hinge rod and the second side table are connected by a linkage structure. When the first side table flips, it drives the hinge rod to rotate. When the hinge rod rotates, it drives the second side table to slide left or right inside the slot. When the first side table flips to a vertical position, the second side table can be completely stored in the slot, thus achieving further folding and storage of the second side table. This further reduces the overall volume of the vibration table, making it easier to transport and store. Attached Figure Description

When the hinge rod 18 rotates, it can drive the second side platform 4 to slide to the left or right inside the slot 5.

[0030] In this embodiment, by rotating and hinged at both ends of the main platform 2, the first side platform 3 is connected to the second side platform 4, which is movably engaged within the first side platform 3. The area of ​​the main platform 2 is expanded by the first side platform 3 and the second side platform 4, thereby effectively increasing the overall area of ​​the vibration table. This can meet the testing requirements of vibration tables when the tested items are large or when there are many items. In addition, the frame 1 is equipped with a flipping mechanism, which can drive the first side platform 3 to automatically flip 90°. After the vibration table is used, the first side platform 3 can be folded and stored by driving it to flip to a vertical position. At the same time, the hinge rod 18 and the second side platform 4 are connected by a linkage structure. When the first side platform 3 flips, it will drive the hinge rod 18 to rotate. When the hinge rod 18 rotates, it can drive the second side platform 4 to slide to the left or right inside the slot 5. When the first side platform 3 flips to a vertical position, the second side platform 4 can be completely stored in the slot 5, thereby achieving further folding and storage of the second side platform 4.

[0032] In this embodiment, the first lead screw 8 rotates, and the adjusting block 9, which is threadedly connected to the first lead screw 8, can drive the adjusting block 9 to move horizontally, thereby driving the support arm 11 on the adjusting block 9 to rotate, thereby driving the first side table 3 at one end of the support arm 11 to flip.

[0033] As a further embodiment of this utility model, a motor 7 is fixedly installed on the frame 1, and the output end of the motor 7 is connected to the first lead screw 8 through a coupling.

[0034] In this embodiment, the motor 7 is started, and the motor 7 drives the first lead screw 8 to rotate. When the first lead screw 8 rotates, the adjusting block 9 is threadedly connected to the first lead screw 8, which can drive the adjusting block 9 to move horizontally, thereby driving the support arm 11 on the adjusting block 9 to rotate, thereby driving the first side table 3 at one end of the support arm 11 to flip.

[0035] As a further embodiment of this utility model, a limiting rod 10 is also fixed on the frame 1, and a limiting hole is opened on the adjusting block 9, with the limiting rod 10 inserted through and inserted into the limiting hole.

[0036] In this embodiment, the limiting rod 10 is inserted through the limiting hole to limit the adjusting block 9 when it moves horizontally on the first lead screw 8, thereby increasing the stability of the adjusting block 9 during movement.

[0037] As a further embodiment of this utility model, the linkage structure includes a groove 12 formed at the bottom of the first side platform 3, a slider 13 fixed to the bottom of the second side platform 4 is slidably engaged in the groove 12, a second lead screw 14 is rotatably mounted at the bottom of the first side platform 3, a threaded sleeve 17 fixed to the slider 13 is threadedly connected to the second lead screw 14, and the second lead screw 14 is connected to the hinge rod 18 through a transmission mechanism. When the hinge rod 18 rotates, it will drive the second lead screw 14 to rotate.

[0038] In this embodiment, the hinge rod 18 rotates while driving the second lead screw 14 to rotate. When the second lead screw 14 rotates, the threaded sleeve 17 is threadedly connected to the second lead screw 14, which drives the threaded sleeve 17 to move horizontally, thereby driving the slider 13 to slide inside the slide groove 12, thereby driving the second side platform 4 to slide inside the slot 5.

[0039] As a further embodiment of this utility model, the transmission mechanism includes a driving bevel gear 15 disposed on the hinge rod 18 and a driven bevel gear 16 disposed on the second lead screw 14, wherein the driving bevel gear 15 and the driven bevel gear 16 are meshed and connected.

[0040] In this embodiment, when the hinge rod 18 rotates, it will drive the driving bevel gear 15 to rotate. The meshing connection between the driving bevel gear 15 and the driven bevel gear 16 will drive the driven bevel gear 16 to rotate, thereby driving the second lead screw 14 to rotate.

[0041] As a further embodiment of this utility model, a stop block is fixed at one end of the second lead screw 14 to prevent the threaded sleeve 17 from slipping off.

[0042] In this embodiment, a threaded sleeve 17 is fixed to one end of the second lead screw 14, and a stop block is used to prevent the threaded sleeve 17 from slipping off the second lead screw 14.

[0043] This invention expands the area of ​​the main table 2 by hinged first side table 3 at both ends of the main table 2, and movably engaging second side table 4 within the first side table 3. This effectively increases the overall area of ​​the vibration table, accommodating vibration tests with large or numerous test objects. Furthermore, a flipping mechanism is installed on the frame 1. Rotation of the first lead screw 8, connected to the threaded adjustment block 9, causes the adjustment block 9 to move horizontally, thereby rotating the support arm 11 on the adjustment block 9. This causes one end of the support arm 11 to flip the first side table 3. The flipping mechanism can automatically flip the first side table 3 90°, thus adjusting the vibration table surface. After use, the first side table 3 can be folded and stored by driving it to flip to a vertical position. When using the first side table 3, it is flipped to a horizontal position. At the same time, the hinge rod 18 and the second side table 4 are connected by a linkage structure. When the first side table 3 is flipped, it will drive the hinge rod 18 to rotate. When the hinge rod 18 rotates, it can drive the second side table 4 to slide to the left or right inside the slot 5. When the first side table 3 is flipped to a vertical position, the second side table 4 can be completely stored in the slot 5, thereby achieving further folding and storage of the second side table 4, further reducing the overall volume of the vibration table, making the vibration table less space occupied, easier to transport, and easier to store.

[0044] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
