[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] This utility model discloses a freight elevator landing door limiting plate assembly, including a support plate 1. A door frame A3 is fixed to the right side of the top of the support plate 1, and a door frame B10 is fixed to the left side of the top of the support plate 1. A door frame C11 is provided on the back side of the top of the support plate 1. A door panel 2 and a landing door 5 are fixed to the front side of the top of the support plate 1. The left side of the interior of the landing door 5 is hollow. A connecting plate 14 is provided on the left side of the interior of the landing door 5. A locking plate 9 and a limiting plate 8 are provided on the left side of the connecting plate 14. Two sets of limiting plates 8 are provided. A handle 12 is fixed to the middle of the right side of the connecting plate 14. A spring 13 is wrapped around the outer wall of the handle 12. A lock groove 15 and a limiting groove 16 are respectively opened on the right side of the door panel 2. With the locking plate 9 and the limiting plate 8 provided at the landing door 5, when the locking plate 9 locks the landing door 5, it will simultaneously drive the two sets of limiting plates 8 into the limiting groove 16 for locking, thereby forming a double locking effect on the landing door 5, which greatly improves the safety during use.
[0021] Furthermore, such as Figure 1 and Figure 2 As shown, a rod groove 6 is provided on the right side of the landing door 5, and a rotating rod 7 is built into the rod groove 6. The two ends of the rotating rod 7 are fixed to the two ends of the inner wall of the rod groove 6, respectively. The rotating rod 7 passes through the interior of the rod block 4, and the rod block 4 is fixed to the inner wall of the door frame A3. The rotating rod 7 and the rod block 4 form a rotating mechanism. When the landing door 5 is opened, the rotating rod 7 will rotate based on the interior of the two sets of rod blocks 4 to ensure the overall strength of the landing door 5, improve the impact resistance of the landing door 5, increase the service life of the landing door 5, and ensure the stability of the landing door when opening and closing.
[0022] Furthermore, such as Figure 3 As shown, the docking plate 14 is adapted to dock with the hollow inner wall of the landing door 5, and the docking plate 14 and the hollow inner wall of the landing door 5 form a sliding mechanism. One end of the spring 13 is attached to the side wall of the docking plate 14, and the other end of the spring 13 is attached to the hollow inner wall of the landing door 5. The handle 12 passes through the right side of the hollow inner wall of the landing door 5, and the locking plate 9 and the limiting plate 8 pass through the left end of the landing door 5. The spring 13 will give the docking plate 14 elasticity, so that during the docking process of the locking plate 9 and the limiting plate 8 with the locking groove 15 and the limiting groove 16, they can be automatically pushed into the interior of the locking groove 15 and the limiting groove 16 by the influence of the elasticity of the spring 13, forming a fast locking effect on the landing door 5.
[0023] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the back of the locking plate 9 is designed to be inclined. The end of the locking plate 9 is inserted into the inside of the locking groove 15, and the end of the limiting plate 8 is inserted into the inside of the limiting groove 16. The locking plate 9 is installed on the rear side of the limiting plate 8. When working, the two sets of limiting plates 8 will enter the inside of the limiting groove 16, so that during use, they work together with the locking plate 9 to form a double locking effect on the landing door 5, thereby improving the strength and safety performance of the landing door 5.
[0024] During operation; when opening the landing door 5, pulling the handle 12 will move the locking plate 9 and the limiting plate 8, causing them to move out of the locking groove 15 and the limiting groove 16. At this time, the landing door 5 can be rotated and opened based on the rotational docking of the rotating rod 7 and the rod block 4. When the landing door 5 is open, goods and personnel can enter the support plate 1. The door frame A3, door frame B10, door frame C11 and landing door 5 will form a surrounding effect, providing protection for the goods and personnel. When closing the landing door 5, the locking plate 9... The inclined surface of the side wall will contact the door panel 2, causing the locking plate 9 to be squeezed into the hollow wall of the landing door 5. During the process of the locking plate 9 being squeezed, it will drive the limiting plate 8 to retract into the hollow wall of the landing door 5 at the same time. Since the locking plate 9 is located behind the limiting plate 8, when the locking plate 9 reaches the position of the locking groove 15, the locking plate 9 will enter the interior of the locking groove 15. At the same time, the limiting plate 8 will reach the interior of the limiting groove 16 and be inserted into the interior of the limiting groove 16. Thus, during use, the stability of the landing door 5 can be well guaranteed. The design is simple and practical.
