[0022] To make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0023] According to Figure 1 , 2 , 3, 4, the present embodiment proposes a vertical shaft cage cage curtain door lifting equipment, including door frame 1, a plurality of curtain plates 2 are arranged in door frame 1, the curtain plate 2 is slidably arranged on the inner side of door frame 1, each curtain plate 2 is arranged in order from top to bottom.

[0024] At least two connecting rods 3 are arranged between adjacent two curtain plates 2, and the upper and lower ends of the connecting rod 3 are pivotally connected with the curtain plate 2.

[0025] The inner side of the door frame 1 is provided with a chain for driving the bottom layer curtain plate 2 to lift up, when the chain is lowered, each curtain plate 2 is unfolded under the action of the connecting rod 3, and the door frame 1 is blocked. After the chain is pulled up, the bottom layer curtain plate 2 is lifted up, driving the upper several groups of curtain plates 2 to lift up together, the connecting rod 3 is folded and stored, and the door frame 1 is opened. The chain lifting in the cage curtain door is a relatively common technical means, which will not be described here.

[0026] The curtain plate 2 includes a main plate 21 and side plates 22 arranged at both ends of the main plate 21, the side plate 22 is slidably connected with the sliding slot 4 arranged on the inner side of the door frame 1, the main plate 21 is plug-in connected with the side plate 22, the outer side of the main plate 21 is provided with a peg connecting piece for fixing the main plate 21, and the connecting rod 3 is detachably connected with the main plate 21.

[0027] The curtain plate 2 is designed in a split type, when the deformed curtain plate 2 is replaced, the connection between the connecting rod 3 and the main plate 21 is released, then the fixing of the main plate 21 by the peg is released, the main plate 21 can be taken out and replaced alone, and the maintenance cost is effectively reduced.

[0028] The main plate 21 is matched with the side plate 22 in a plug-in manner. After the fixing of the engagement rod 3 and the main plate 21 is released, the fixing of the bolt connecting piece to the main plate 21 is released, and then the two ends of the main plate 21 can be pulled out of the side plate 22. Specifically, the main plate 21 is provided with a plug block 23 on the side facing the side plate 22, the plug block 23 is fixedly connected with the main plate 21, the side plate 22 is provided with a plug slot 24 on the side facing the main plate 21, the plug slot 24 is arranged at the upper end of the side plate 22, and the plug block 23 is slidably connected with the plug slot 24. When the main plate 21 is installed, the plug block 23 at the two ends of the main plate 21 is pushed into the plug slot 24 arranged at the upper end of the side plate 22, so that the main plate 21 is convenient to replace and maintain.

[0029] It is worth further explaining that the plug block 23 is a T-shaped plug block, and the plug slot 24 is a T-shaped plug slot matched with the plug block 23. The T-shaped structure makes the plug block 23 not easy to be separated from the plug slot 24. Because a part of the T-shaped plug block is clamped by the edge of the T-shaped plug slot, it has a good limiting effect in the plane perpendicular to the sliding direction, can bear a large lateral force, and can ensure the stability of the movement track of the plug block 23. When the plug block 23 is subjected to a large pressure or tension, the contact part of the T-shaped structure can effectively transmit the force to each supporting part of the plug block 23, thereby improving the bearing capacity of the matching part of the main plate 21 and the side plate 22.

[0030] The bolt connecting piece is arranged outside the side plate 22 and is used for fixing the plug block 23 inserted into the plug slot 24. Specifically, the bolt connecting piece comprises a fixing bolt 25 assembled outside the side plate 22, the fixing bolt 25 is threadedly connected with a second threaded hole 27 arranged outside the side plate 22, and the second threaded hole 27 is threadedly connected with a first threaded hole 26 arranged outside the plug block 23. After the plug block 23 is pushed into the plug slot 24, the first threaded hole 26 outside the plug block 23 coincides with the second threaded hole 27 outside the side plate 22, the fixing bolt 25 is screwed into the second threaded hole 27, and the fixing of the plug block 23 is completed.

[0031] The engagement rod 3 is arranged between two adjacent main plates 21 and plays a role of engagement. Specifically, the upper end and the lower end of the engagement rod 3 are both provided with a movable slot 32, a pivot 31 is slidably arranged in the movable slot 32, one end of the pivot 31 is fixedly connected with the main plate 21, and the other end of the pivot 31 is provided with a limiting piece for preventing the engagement rod 3 from falling off. When the main plate 21 is lifted upward, the main plate 21 can pull the next main plate 21 through the engagement rod 3, and the pivot 31 can slide and rotate in the movable slot 32, so that the folding and unfolding of the engagement rod 3 is facilitated.

[0032] In the preferred scheme, the limiting piece comprises a nut 33, the nut 33 is sleeved outside the pivot 31, the nut 33 is threadedly connected with the pivot 31, and the diameter of the nut 33 is greater than the width of the movable slot 32. When the engagement rod 3 is removed from the pivot 31, the nut 33 is screwed out of the pivot 31.

[0033] The working principle of the present application is:

[0034] The inner side of the door frame 1 is provided with a chain for driving the bottom layer of curtain plates 2 to lift up. When the chain is lowered, each curtain plate 2 is unfolded under the action of the connecting rod 3 to block the door frame 1. After the chain is pulled up, the bottom layer of curtain plates 2 is lifted up to drive the upper several groups of curtain plates 2 to lift up together, and the connecting rod 3 is folded up. The door frame 1 is opened. The curtain plate 2 is designed in a split type. When the deformed curtain plate 2 is replaced, the connection between the connecting rod 3 and the main plate 21 is released, then the fixing of the main plate 21 by the bolt connection is released, and the main plate 21 can be taken out and replaced alone, so that the maintenance cost is effectively reduced.
