DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1-3As shown, a lifting isolation lock device comprises a lock box 1, the front and rear ends of the lock box 1 are symmetrically fixed with a cover plate 2 by screws, a lock hole 3 is opened at the lower part of the outer end of the cover plate 2, an axial hole 4 and a through hole 5 are arranged on the lock hole 3, the axial hole 4 is opened at the inner end of the lock hole 3, the through hole 5 is opened at the right side inside the lock hole 3, and a male lock pin 6 is nested on the through hole 5 at the front end, a lock tongue 7 and a shaft sleeve 8 are arranged on the male lock pin 6, the lock tongue 7 is integrally connected to the middle of the left side of the male lock pin 6, the shaft sleeve 8 is sleeved on the rear end of the male lock pin 6, the rear end of the shaft sleeve 8 is integrally connected with a female lock pin 9, the left end of the female lock pin 9 is nested in the through hole 5 at the rear end, and a guide shaft 10 is integrally connected with the middle of the right end of the female lock pin 9 and the male lock pin 6, the guide shaft 10 is integrally connected with the guide shaft 10, and the guide shaft 10 is integrally connected with the guide shaft 10. A docking seat 11 is mounted on the right end of the guide shaft 10, a spring 12 is mounted between the docking seat 11 and the guide shaft 10, an isolation shaft 13 is nested on the shaft hole 4, an isolation rod 14 and a transmission arm 15 are arranged on the isolation shaft 13, the isolation rod 14 is mounted on the front end of the isolation shaft 13, the transmission arm 15 is integrally formed and connected to the front end of the isolation shaft 13, a transmission rod 16 and a locking groove 17 are arranged on the isolation rod 14, the transmission rod 16 is fixed to the lower rear end of the isolation rod 14 by screws, and a transmission groove 18 is opened in the middle of the transmission rod 16, the locking groove 17 is symmetrically opened below the right end of the isolation rod 14, and a shift rod 19 is fixed to the end of the transmission arm 15 by screws, and the shift rod 19 is nested in the transmission groove 18.

[0016] Specific usage: Under normal conditions, the male lock pin 6 and the female lock pin 9 always have a leftward force under the action of the spring 12. Under the action of this force, the lock tongue 7 is nested in the upper lock groove 17 to lock the isolation rod 14, so that the isolation rod 14 cannot move; when the crew uses the key to operate in the car, the key pushes the male lock pin 6, and the male lock pin 6 is forced to move to the right while driving the lock tongue 7 to move out of the upper lock groove 17. At this time, turning the key drives the isolation shaft 13 to rotate, and the rotation of the isolation shaft 13 drives the transmission arm 15 The lever 19 rotates, and the rotation of the lever 19 drives the isolation rod 14 on the transmission rod 16 to move upward; when the attendant operates outside the vehicle, the key first pushes open the female lock pin 9, and the female lock pin 9 is forced to move to the right while driving the male lock pin 6 to move to the right through the shaft sleeve 8. The male lock pin 6 moves to the right and drives the lock tongue 7 to move out of the upper lock groove 17; when the isolation operation is completed and the attendant key is removed, the male lock pin 6 and the female lock pin 9 drive the lock tongue 7 to be nested in the lower lock groove 17 under the action of the spring 12 to lock the isolation rod 14.

[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
