[0002] A passenger and freight elevator is a freight elevator commonly used in building construction to transport materials. Currently, the elevator is generally composed of two doors that can be pushed open to the left and right. The existing doors are generally provided with bolts, but the bolts on existing elevators are simple; however, the bolts can be opened from inside the elevator, and the two doors are not flat when closed. In addition, the elevator is sometimes easily affected by strong winds and easily blown open by strong winds.

[0003] Currently, a Chinese utility model with publication number CN208236185U discloses a bolt structure for a building elevator door. The structure comprises left- and right-hand doors, with a bolt disposed between the left and right doors. The bolt comprises a first connecting plate secured to the left door, an L-shaped first stopper formed on the side of the first connecting plate near the right door, a slot formed between the first stopper and the first connecting plate, a second connecting plate inserted into the slot, the second connecting plate secured to the right door, an L-shaped second stopper formed on the side of the second connecting plate near the left door, a bolt rod disposed between the second stopper and the second connecting plate, a counterweight formed at the lower end of the bolt rod, a support fixed to the middle of the bolt rod, and a strip-shaped shifting block secured to the support through the second stopper. The structure is simple, capable of closing the elevator door, and resists being blown open by strong winds.

[0004] The door bolt structure uses a counterweight block to close the door, but during use, the stability of the counterweight block is generally poor, resulting in low locking performance of the adjusted door bolt. At the same time, when the door bolt is damaged, it is inconvenient to disassemble and replace the door bolt, which has limitations in use. Utility Model Content
