The two tail ends of the connecting rod penetrate through the side wall, far away from the back, of the supporting block body, the first connecting rod and the second connecting rod are located on the same straight line, a first fan-shaped cavity and a second fan-shaped cavity perpendicular to the through hole are arranged in the supporting block body on the two sides of the through hole respectively, the tail end of the first fan-shaped cavity is communicated with the roller groove, the tail end of the second fan-shaped cavity is communicated with the outside, and the first connecting rod and the second connecting rod are arranged in the first fan-shaped.
The second connecting rod arranged at the other end of the rotating shaft can be used as a handle for rotating the rotating shaft and the first connecting rod through a lever principle, the position of the rolling shaft can be conveniently adjusted, and the first fan-shaped cavity and the second fan-shaped cavity are respectively used for providing space for rotation of the first connecting rod and the second connecting rod.
The part of the second connecting rod, which is arranged outside the supporting block body, is connected with a baffle, the upper surface of the baffle is provided with a cushion pad, and the included angle between the baffle and the top surface of the supporting block body is 120-150 degrees when the rolling shaft falls to the bottom of the arc groove.
When the roller shaft falls to the roller shaft groove lower extreme, supporting shoe body top surface level, frictional force is big between graphite boat and supporting shoe body top surface, receives external force and is difficult for sliding, protects the graphite boat, baffle and supporting shoe body top surface contained angle are 120 + 150 this moment, the baffle can further avoid the graphite boat slip that external force is too big and lead to, blotter on the baffle can reduce the impact force between baffle and graphite boat, the protection graphite boat is not damaged, further protection graphite boat, realize the duplicate protection of graphite boat.
The length of the first connecting rod is 3-5 times of that of the second connecting rod, and the weight of the rolling shaft is 3-5 times of the total weight of the baffle and the cushion.
When taking out from square board, under lever principle effect, the roller bearing can fall automatically, and the baffle upwards overturns, avoids, and the graphite boat slides, can the hand baffle slow down roller bearing falling speed, if the graphite boat that stews receives stronger exogenic action and slides and when colliding with the baffle, its impact need be greater than 9-25 times of roller bearing gravity just can make the baffle push down the baffle upwarp, and the ordinary external force that the graphite boat received is difficult to reach this effect, therefore has promoted the guard action of baffle to the graphite boat greatly, improve equipment's stability.
One top surface of the sector cavity is a horizontal plane, and the included angle between the bottom surface and the top surface is 30-60 degrees.
The roller comprises a horizontal shaft and rollers sleeved on two sides of the horizontal shaft, the rollers can freely rotate around the horizontal shaft, the middle of the horizontal shaft is fixedly connected with a first connecting rod, the side wall of the roller groove far away from the rotating shaft comprises an upper section and a lower section of arc surface which both use the through hole as a circle center, the diameter of the upper section of arc surface is larger than that of the lower section of arc surface, and the radius of the lower section of arc surface is equal to the sum of the first connecting rod, the radius of the rotating shaft and the.
According to the roller, the radius of the lower arc surface is equal to the sum of the first connecting rod, the radius of the rotating shaft and the radius of the roller, so that after the square plate is pulled out, the roller falls under the action of gravity and falls to the lower half section of the arc groove, the outer side of the roller is in contact with the lower arc surface, friction force is generated between the arc surface and the roller, the roller is changed from the original relative static state to the rotating state, the roller falls gradually in the rotating process of the roller attached to the arc surface, the falling speed of the roller is reduced, the phenomenon that the falling speed of the roller impacts the bottom of the arc groove too fast is avoided, the roller and a supporting block body are protected from being damaged, noise and vibration generated by falling of the roller are reduced, and the diameter of the upper arc surface is larger than that of the lower arc surface, so that the roller does not.
When the first connecting rod rotates to the top surface of the first fan-shaped cavity, the first connecting rod is horizontal, the top surface of the cushion pad is lower than the top surface of the supporting block body, the top surface of the roller is higher than the top surface of the supporting block body, and the roller is in contact with or spaced from the top surface of the square plate by 1-3 mm.
The top surface of the fan-shaped cavity is horizontal, the roller can be limited from being turned out of the roller groove, and when the connecting rod rotates to the top surface of the fan-shaped cavity, the top surface of the cushion pad is lower than the top surface of the supporting block body, so that the situation that the baffle and the cushion pad block the graphite boat to continuously slide under the action of the pushing device can be avoided.
