A vertical roller is provided on the rotating switch shaft of the deviation switch, which is convenient for the staff to shake the vertical roller left and right to adjust the switch left and right. Since the vertical roller protrudes from the outside of the deviation switch, the vertical roller on the deviation switch may be subjected to forces in other directions due to accidental touch during operation, causing the vertical roller to damage the rotating switch shaft on the deviation switch.

[0007] Preferably, a fixing bolt is screwed onto the rotary switch shaft, and the base is located between the rotary switch shaft and the fixing bolt.
[0008] Preferably, a limit pin is inserted at one end of the latch.
[0009] Beneficial Effects
[0010] The utility model provides an anti-impact deviation vertical roller, which has the following beneficial effects:
[0011] 1. A base is provided on the rotating switch shaft of the belt conveyor deviation switch, and a connecting rod is inserted on the base. The connecting rod is connected to the vertical roller shaft and the sleeve through a stud. The sleeve can be shaken left and right to control the left and right rotation of the rotating switch shaft. When subjected to external force, the sleeve itself can rotate to play a certain force release role. At the same time, the sleeve can be pulled forward. The sleeve drives the vertical roller shaft, the stud and the connecting rod to bend forward with the pin as the axis through the first deep groove ball bearing and the second deep groove ball bearing, and at the same time, a pair of torsion springs are bent under force. When the external force disappears, the torsion spring resets, driving the sleeve, the vertical roller shaft, the stud and the connecting rod to reset at the same time, so as to avoid the vertical roller being damaged by force on the rotating switch shaft.
