Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 2 , Figure 3 and Figure 4The utility model provides an embodiment of a furniture drop test device, comprising a mounting plate 5, a plurality of mounting grooves 14 are provided inside the mounting plate 5, a sliding column 25 is fixedly connected inside the mounting groove 14, two sliding plates 13 are slidably connected to the outer side of the sliding column 25, a motor 28 is fixedly connected to the top of the mounting plate 5, a transmission disk 10 is fixedly connected to the output end of the motor 28, a motion rod 9 is rotatably connected to both ends of the outer side of the transmission disk 10, a rotating block 11 is rotatably connected to the outer side of the motion rod 9, a fixed rod 12 is rotatably connected to the bottom side of the rotating block 11, an auxiliary plate 21 is fixedly connected to the bottom of the sliding plate 13, two telescopic rods 23 are fixedly connected to the outer side of the auxiliary plate 21, a clamping arc plate 22 is fixedly connected to the outer side of the telescopic rod 23, a spring 24 is sleeved on the outer side of the telescopic rod 23, and a lifting component is installed on the outer side of the mounting plate 5.
[0031] Specifically, the mounting plate 5 is used to install various structures. There are multiple sliding columns 25 inside the mounting groove 14. The sliding plate 13 slides outside the sliding column 25. The motor 28 is fixed on the top of the mounting plate 5. The motor 28 is fixed to ensure the stability of the motor 28. By starting the motor 28, the output end of the motor 28 rotates to drive the transmission disk 10 to rotate. Under the action of the transmission disk 10, the rotation of the rotating block 11 is driven, so that the rotating block 11 and the motion rod 9 rotate, and then the rotation of the rotating block 11 is driven. Under the traction of the rotating block 11 and the connection of the fixed rod 12, the two driving sliding plates 13 move in opposite directions, so that the sliding plate 13 moves along the outer side of the sliding column 25, thereby driving the auxiliary plate 21 fixed to the sliding plate 13 to move, thereby driving the movement of the telescopic rod 23, and then driving the movement of the clamping arc plate 22, and finally achieving the effect of clamping an object.
[0032] Reference Figure 1 and Figure 2 The lifting assembly includes a base plate 1, a motor 2 is fixedly connected to the top of the base plate 1, a bevel gear 15 is fixedly connected to the output end of the motor 2, a limiting block 3 is fixedly connected to the top of the base plate 1, a protective plate 4 is fixedly connected to the top of the limiting block 3, a threaded rod 17 is rotatably connected to the inside of the protective plate 4, a bevel gear 2 16 is fixedly connected to the outside of the bottom of the threaded rod 17, a threaded block 18 is threadedly connected to the outside of the threaded block 18, and a lifting plate 7 is fixedly connected to the outside of the threaded block 18.
[0033] Specifically, the bottom plate 1 is used to place the tested object, so as to facilitate clamping and fixing. By starting the motor 2, under the action of the output end of the motor 2, the bevel gear 15 is driven to rotate, and then the meshing bevel gear 2 16 is driven to rotate, and then the threaded rod 17 is driven to rotate inside the protective plate 4. Under the action of the limit block 3, the threaded rod 17 has a stabilizing effect, so that the threaded block 18 performs a threaded motion along the outer wall of the threaded rod 17, thereby achieving a rising and falling effect.
[0034] Reference Figure 2 A sliding rod 20 is fixedly connected to the top of the bottom plate 1, and a slider 19 is slidably connected to the outside of the sliding rod 20.
[0035] Specifically, the slider 19 slides along the outside of the sliding rod 20 , and under the action of the slider 19 , the lifting plate 7 can be lifted and lowered stably.
[0036] Reference Figure 1 and Figure 2 The top of the mounting plate 5 is fixedly connected to two connecting plates 6, the outer sides of the tops of the two connecting plates 6 are fixedly connected to a lifting plate 7, and the outer sides of the lifting plate 7 are fixedly connected to a threaded block 18 and a slider 19 respectively.
[0037] Specifically, the connecting plate 6 is used to connect the mounting plate 5. The threaded movement of the threaded block 18 drives the lifting plate 7 to move up and down. The action of the slider 19 ensures that the lifting plate 7 can be lifted and lowered stably. When the lifting plate 7 rises or falls, the connecting plate 6 can drive multiple structures below the lifting plate 7 to rise and fall.
[0038] Reference Figure 2 and Figure 3 One end of the spring 24 is fixedly connected to the outside of the auxiliary plate 21 , and the other end of the spring 24 is fixedly connected to the outside of the clamping arc plate 22 .
[0039] Specifically, two ends of the spring 24 are respectively fixed to the outside of the auxiliary plate 21 and the outside of the clamping arc plate 22, so that the elasticity of the spring 24 is brought into play.
[0040] Reference Figure 2 , bevel gear 1 15 and bevel gear 2 16 are meshingly connected.
[0041] Specifically, under the active rotation of bevel gear 15, bevel gear 2 16 is driven.
[0042] Reference Figure 1 and Figure 2 The output end of the motor 2 is rotationally connected to the limit block 3, and the bevel gear 15 is rotationally connected to the inside of the limit block 3.
[0043] Specifically, under the action of the limit block 3, it is ensured that the output end of the motor 2 can rotate stably, and drive the bevel gear 15 to rotate stably inside the limit block 3.
[0044] Reference Figure 1 and Figure 2 The four corners of the bottom end of the base plate 1 are fixedly connected with supporting legs, and the bottom of the supporting legs is provided with anti-slip pads.
[0045] Specifically, the support legs facilitate the placement of the base plate 1 , and the anti-skid pads prevent the support legs from deviating and slipping.
[0046] Working principle: When it is necessary to perform a drop test on the furniture, at this time, by starting the motor 12, under the action of the output end of the motor 12, the bevel gear 15 is driven to rotate, so that the bevel gear 15 drives the meshing bevel gear 2 16 to mesh and rotate, and then drives the rotation of the threaded rod 17, so that the threaded block 18 performs threaded movement along the outside of the threaded rod 17, and then drives the lifting and lowering of the lifting plate 7, so that the lifting plate 7 drives the connection plate 6 to descend, and then drives the multiple structures below to descend, so that the clamping mechanism descends to the top of the bottom plate 1, at this time, by starting the motor 28, under the action of the output end of the motor 28, the transmission disk 10 is driven to rotate, so that the transmission disk 10 is in motion. Under the action of the movable rod 9, the rotating block 11 is driven to rotate, so that the rotating block 11 drives the sliding plate 13 to slide under the action of the fixed rod 12, and then the sliding of the sliding plate 13 drives the sliding of the auxiliary plate 21, and under the action of the clamping arc plate 22, the furniture can be clamped, and under the action of the spring 24, the clamping arc plate 22 can be clamped more tightly, and then the motor 1 2 is started to make the threaded block 18 rise along the outside of the threaded rod 17, thereby driving the multiple linked mechanisms to rise, and then by starting the motor 2 8, the clamping arc plate 22 is relaxed, so that the furniture falls from a high place, thereby achieving a test that can be used to test the furniture's fall.
