second pushing rod 1002, the second spring 1005 is located outside the second pushing rod 1002 and between the second conical pushing head 1003 and the second tank 1001, when the adjusting nut is in an initial position, the second spring 1005 is in a compressed state, so that the second conical pushing head 1003 is attached to the second tank 1001, the non-newtonian fluid in the outer box 1 and the inner box 2 is not subjected to enough pressure to overcome the elastic force of the second spring 1005 to push the second conical pushing head 1003 to move downwards, it is ensured that the outer box 1 and the inner box 2 are filled with the non-newtonian fluid, the position of the adjusting nut 1004 on the second pushing rod 1002 can be adjusted manually, that the position of the second conical pushing head 1003 in the second tank 1001 can be adjusted, so that part of the non-newtonian fluid flows into the second tank, and then the pressure of the non-Newtonian fluid between the outer box body 1 and the inner box body 2 is adjusted, so that different working condition requirements are met.
The working principle is as follows: in the initial state, the non-newtonian fluid is filled between the outer casing 1 and the inner casing 2, the extrusion mechanism 8 and the vibration heating mechanism 9 are filled with the non-newtonian fluid, the buffer mechanism 10 does not contain the non-newtonian fluid, and the non-newtonian fluid between the outer casing 1 and the inner casing 2 has a certain pressure under the action of the first spring 806 and the second spring 1005 provided in the extrusion mechanism 8 and the buffer mechanism 10. When large impact is applied to transportation, the viscosity of the non-Newtonian fluid changes at the highest speed, so that the inner box body 2 is prevented from shaking, when general vibration or impact occurs, the inner box body 2 generates small displacement, because the resistance at the throttling hole 919 is large, the non-Newtonian fluid flows into the caching mechanism 10 after being pressed, when the impact disappears, the compression spring 6 pushes the inner box body 2 to reset, the second conical pushing head 1003 arranged in the caching mechanism 10 pushes the non-Newtonian fluid to enter the extrusion mechanism 8 through the second one-way valve 12, and the non-Newtonian fluid is slowly supplemented between the outer box body 1 and the inner box body 2 through the vibration heating mechanism 9, so that dynamic balance is realized. When the low-temperature starting is carried out, the vibration heating mechanism 9 heats non-Newtonian fluid, the long-stroke electromagnet 7 pushes the extrusion mechanism 8 to act, the extrusion mechanism 8 presses the non-Newtonian fluid into the vibration heating mechanism 9, the vibration heating mechanism 9 vibrates and uniformly heats the non-Newtonian fluid, the non-Newtonian fluid is input into a space between the outer box body 1 and the inner box body 2 through the hose, then flows into the cache mechanism 10 through the hose at the upper end of the outer box body 1 and the first one-way valve 11, then the long-stroke electromagnet 7 is separated from the extrusion mechanism 8 and returns, the cache mechanism 10 presses the non-Newtonian fluid in the cache mechanism into the extrusion mechanism 8 through the second one-way valve 12, and the steps are repeated until the PCB 5 can be started. The device simple structure not only can prevent to strike the destruction that produces the PCB board, can heat moreover, realizes the low temperature start-up of PCB board, has stronger practicality.
The present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make various modifications without creative efforts from the above-described conception, and fall within the scope of the present invention.
