Fig. 1 is a schematic structural view of a gear linkage type safety mechanism of an in-box support vehicle provided by the invention, and as shown in fig. 1, the gear linkage type safety mechanism of the in-box support vehicle provided by the invention comprises: the auxiliary handle 1, the movable handle 2, the compression spring 3, the transverse rack 4, the gear 5, the longitudinal rack 6, the side stop 7 and the bolt 8.

The safety mechanism is integrally arranged at the rear end of the second group of folding wheels of the supporting vehicle, and plays a role in preventing the second group of folding wheels from being completely dragged out of the supporting vehicle under the condition of not lowering the second group of folding wheels so as to cause vehicle overturning or impact.

The gear 5 and its axle are mounted in the middle of the mechanism, and can be directly mounted on the beam of the supporting vehicle, or can be mounted on the fixed bottom plate, and the fixed bottom plate is mounted on the beam. The gear 5 drives the transverse rack 4 and the longitudinal rack 6 to reciprocate simultaneously, the transverse rack 4 is perpendicular to the longitudinal rack 6, and the side stop 7 is used for limiting so as to ensure the matching relation with the gear. The transverse rack 4 and the longitudinal rack 6 are respectively provided with 8 teeth, and the initial position matched with the gear is the middle line of the racks. The transverse rack 4 is connected with the movable handle 2 into a whole, and the compression spring 3 provides locking and resetting elasticity. The lock tongue 8 is connected with the longitudinal rack 6 into a whole and is driven by the gear to carry out unlocking and locking actions.

The device relies on spring bolt 8 and outside dog cooperation locking, utilizes the gear to realize the linkage of horizontal rack 4 and vertical rack 6 during the unblock, through holding assist handle 1 and activity handle 2 tightly, drives horizontal rack 4 translation left, and then makes anticlockwise rotation through gear 5, and then drives vertical rack 6 and upwards translates, and then drives spring bolt 8 indentation, realizes the function of unblanking. After the unlocking is finished, the auxiliary handle 1 and the movable handle 2 are loosened, and the integral mechanism can be restored to the initial state by utilizing the elastic force of the compression spring 3.

When the supporting vehicle is taken out of the box, the lock tongue 8 can collide with the box body for stopping, so that the supporting vehicle is prevented from being further dragged out, and a safety effect is achieved. And after the operator confirms that the second group of folding wheels are placed, unlocking the safety mechanism. During unlocking, the auxiliary handle 1 and the movable handle 2 are held tightly to drive the transverse rack 4 to translate leftwards, and the gear 5 of the transmission part transmits displacement to the longitudinal rack 6 and the lock tongue 8, so that the lock tongue is retracted and unlocked.

When the supporting vehicle enters the box, the safety mechanism can realize automatic locking. Promote the supporting car and enter the case, the wedge inclined plane collision box backstop of spring bolt 8, under the effect of vertical component, 8 upwards indents of spring bolt, and spring bolt 8 and vertical rack 6 are the active part this moment, drive horizontal rack 4 and turn left translation, and spring bolt 8 breaks through and resumes initial locking state under compression spring 3's effect behind the box backstop.
