Referring to fig. 3 and 4, the fixing rod 4 (see fig. 2) is disposed on the positioning rod 32, the fixing rod 4 is disposed perpendicular to the positioning rod 32 and passes through the first spring 34, and when the positioning rod 32 is lifted, the fixing rod 4 is lifted and lowered along with the lifting and lowering of the positioning rod 32. One end of the fixing rod 4 far away from the positioning rod 32 is provided with a limiting wheel 5, the limiting wheel 5 is provided with first limiting teeth 51, the safety door 12 is connected with limiting strips 6 in a sliding mode, the limiting strips 6 are provided with second limiting teeth 61, the first limiting teeth 51 and the second limiting teeth 61 are meshed and arranged, the limiting strips 6 are provided with operating columns 62, the operating personnel move the operating columns 62, the limiting strips 6 are moved, the moving direction of the limiting strips 6 is perpendicular to the moving direction of the positioning rod 32, and therefore the first limiting teeth 51 and the second limiting teeth 61 can be connected with each other or separated from each other. When it is necessary to limit the spacing wheel 5, the second spacing teeth 61 of the spacing strips 6 are engaged with the first spacing teeth 51 of the spacing wheel 5, so that the spacing wheel 5 can be locked, the positioning rod 32 is limited, and the positioning rod 32 and the mounting groove 21 are reliably connected.

Referring to fig. 5 and 6, in order to reduce accidental injury caused by the first limiting teeth 51 and the second limiting teeth 61, the safety door 12 is provided with the protective cover 7, the limiting wheel 5 and the limiting strip 6 are both positioned in the protective cover 7, and dust can be reduced from entering the protective cover 7 through the protective cover 7, so that the service lives of the limiting strip 6 and the limiting wheel 5 can be prolonged. In order to facilitate the transverse movement of the limiting strip 6 through the operating column 62, a waist-shaped hole 71 is formed in the protective cover 7, the length direction of the waist-shaped hole 71 is consistent with the sliding direction of the limiting strip 6, and the operating column 62 is arranged in the waist-shaped hole 71 in a penetrating mode, so that a movement space can be provided for the operating column 62 through the waist-shaped hole 71. The end part of the operating column 62 extending out of the waist-shaped hole 71 is hinged with a locking column 76, a group of locking blocks 77 is arranged on the protective cover 7, and the locking column 76 is clamped between the two locking blocks 77. When the limiting strip 6 and the limiting wheel 5 are in the mutually connected state, the locking column 76 is clamped in the locking block 77, so that the first limiting tooth 51 and the second limiting tooth 61 are always in the meshed state, the positioning rod 32 and the mounting groove 21 can be reliably connected, and misoperation of workers is further reduced.

Referring to fig. 4, a sliding block 8 is fixedly arranged on the wall surface of the safety door 12, a group of grooves 81 is formed in the sliding block 8, rollers 82 are arranged at two ends of the limiting strip 6, and the rollers 82 are connected in the grooves 81 at corresponding positions in a rolling mode. When moving spacing 6, can drive the gyro wheel 82 and roll in recess 81, on the one hand, can reduce the frictional force between spacing 6 and the emergency exit 12, on the other hand can carry out spacingly to spacing 6 through recess 81 to can restrict the movement track of spacing 6, thereby can make spacing 6 and spacing wheel 5 reliably connect. A limit block 72 is arranged on the safety door 12, a second spring 75 is arranged between the limit block 72 and the limit strip 6, and the length direction of the second spring 75 is the sliding direction of the limit strip 6. The second spring 75 enables the stop bar 6 to automatically reset when the operating post 62 is not under load. When the operation post 62 is not atress, spacing 6 can be automatic to cooperate with spacing wheel 5 to be connected to can lock spacing wheel 5, make locating lever 32 reliably fix in mounting groove 21.

The implementation principle of the above embodiment is as follows: when the safety door 12 is disassembled, firstly, the operator moves the operating column 62 to the position far away from the positioning rod 32 to disconnect the first limiting teeth 51 and the second limiting teeth 61, then the operator moves the limiting rod 37 to the position far away from the fixing seat 2, the positioning rod 32 moves along the direction far away from the fixing seat 2, the positioning rod 32 can be disconnected from the mounting groove 21, and therefore the safety door 12 can be separated from the frame 11.

When the safety door 12 is installed, firstly, an operator moves the operating column 62 to a position far away from the positioning rod 32 to disconnect the first limiting tooth 51 and the second limiting tooth 61, then the operator moves the limiting rod 37 to a position far away from the fixing seat 2, so that the first spring 34 can be compressed through the limiting plate 36, the central hole in the fixing sleeve 31 and the axis of the installation groove 21 are positioned at the same central line, then the limiting rod 37 is loosened, the first spring 34 exerts an upward force on the limiting plate 36 through the self resilience force, so that the positioning rod 32 can bear an upward force, so that the positioning rod 32 and the installation groove 21 can be connected with each other, finally, the operating column 62 is loosened, the limiting strip 6 moves to a position near the limiting wheel 5 through the second spring 75, the first limiting tooth 51 and the second limiting tooth 61 are meshed with each other, and then the locking column 76 is clamped between the two locking blocks 77, the positioning rod 32 and the mounting groove 21 can be accurately positioned.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
