[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a speed controller rapid vibration detection device includes a rack 1, a fixing assembly 6 is installed inside the rack 1, and the fixing assembly 6 includes two screw rods 601 rotatably connected to the top outer wall of the rack 1, and the parameters of the two screw rods 601 are consistent, one of the screw rods 601 is rotatably connected to the top outer wall of the screw rod 601, and the hinge seat 602 is rotatably connected to the inner part of the hinge seat 602. A limit rod 603 is fixedly connected to the top outer wall of the other screw rod 601, and a plurality of equally spaced slots are provided on the top of the slot, and the limit rod 603 can be engaged in the plurality of slots.

[0025] The outer walls at the bottom of the two screw rods 601 are rotatably connected to a same pressing plate 605 . A sprocket 606 is fixedly sleeved on the bottom of the circumferential outer walls of the two screw rods 601 . The two sprockets 606 are sleeved with a same chain 607 .

[0026] A rubber pad 5 is provided on the bottom outer wall of the pressing plate 605 and the bottom inner wall of the storage rack 1 , and the two rubber pads 5 are arranged opposite to each other.

[0027] The extension column at the top of the card seat 604 drives one screw rod 601 to rotate, and the sprocket 606 connected to the screw rod 601 will rotate synchronously, which can drive the other chain 607 to rotate synchronously through the chain 607, so that the two screw rods 601 can keep rotating synchronously, and the two will move downward synchronously along the upper half of the storage rack 1, and then the pressure plate 605 will be driven toward the controller, so that the controller can be fixed. Since the bottom inner wall of the storage rack 1 and the bottom wall of the pressure plate 605 are both provided with rubber pads 5, the rubber pads 5 can continue to move after squeezing the controller, so that the screw rod 601 can continue to rotate, so that one of the grooves of the card seat 604 at its top can remain parallel to the limit rod 603, and then the hinge seat 602 is rotated and the limit rod 603 is flipped so that it is engaged in the groove of the card seat 604. Since the rotation axis of the card seat 604 does not coincide with the rotation axis of the hinge seat 602, the card seat 604 will not rotate, and the position of the pressure plate 605 will not change.

[0028] like Figure 1 and Figure 2 As shown, a spring 2 is fixedly connected to each of the four corners of the bottom outer wall of the rack 1 , and a vibrator 3 is fixedly installed on the bottom outer wall of the rack 1 .

[0029] By starting the vibrator 3 and cooperating with the spring 1 2 , the rack 1 can be vibrated rapidly, thereby performing detection.

[0030] like Figure 2 and Figure 4As shown, a shock absorbing assembly 7 is installed at the bottom of the four springs 2, and the shock absorbing assembly 7 includes a same connecting plate 701 fixedly connected to one end of the bottom of the four springs 2.

[0031] A damper 702 is fixedly connected to each of the four corners of the bottom outer wall of the connecting plate 701. One end of the bottom of the four dampers 702 is fixedly connected to the same support frame 4. Four springs 2 703 are fixedly connected between the support frame 4 and the connecting plate 701. The four springs 2 703 are respectively surrounded by the outside of the four dampers 702.

[0032] The vibration generated by the vibrator 3 will also be transmitted to the connecting plate 701 through the spring 1 2. The spring 2 703 at the bottom of the connecting plate 701 can ensure that it can move up and down, and the damper 702 inside the spring 2 703 can slow down the expansion and contraction speed of the spring 2 703 and eliminate the vibration, effectively preventing the device from being displaced due to vibration.

[0033] like Figure 3 As shown, a horizontal plate is provided at the bottom of the outer circumferential wall of the card seat 604, and an extension column is rotatably connected to the top of the extension plate. The screw rod 601 can be driven to rotate through the extension column and the horizontal plate, thereby ensuring that the driving of the device is convenient enough.

[0034] The utility model provides a fast vibration detection device for a speed controller, the specific working principle of which is as follows:

[0035] When the device is working, the adjustment group controller to be tested is placed inside the rack 1, and then a screw rod 601 is driven to rotate through the extension column on the top of the card seat 604, and the sprocket 606 connected to the screw rod 601 will rotate synchronously, which can drive the other chain 607 to rotate synchronously through the chain 607, so that the two screw rods 601 can keep rotating synchronously, and the two will move downward synchronously along the upper half of the rack 1, and then the pressure plate 605 will be driven to move closer to the controller, so that the controller can be fixed. Since the bottom inner wall of the rack 1 and the bottom wall of the pressure plate 605 are both provided with rubber pads 5, the rubber pads 5 can continue to move after squeezing the controller, so that the screw rod 601 can continue to rotate, so that one of the recesses of the card seat 604 on its top is pressed. The groove can be kept parallel to the limit rod 603, and then the hinge seat 602 is rotated and the limit rod 603 is flipped so that it is engaged in the groove of the clamping seat 604. Since the rotation axis of the clamping seat 604 does not coincide with the rotation axis of the hinge seat 602, the clamping seat 604 will not be able to rotate, and the position of the pressure plate 605 will not change. At this time, the vibrator 3 is started again, and the spring 1 2 can make the storage rack 1 vibrate rapidly, so that detection can be carried out. The vibration generated by the vibrator 3 will also be transmitted to the connecting plate 701 through the spring 1 2. The spring 2 703 at the bottom of the connecting plate 701 can ensure that it can move up and down, and the damper 702 inside the spring 2 703 can slow down the expansion and contraction speed of the spring 2 703 and eliminate the vibration, effectively preventing the device from being displaced due to vibration.
