Description

Technical Field

[0001] This utility model belongs to the field of elevator manufacturing technology, and is particularly related to an elevator door structure. Background Technology

[0002] Elevator doors are typically slidably suspended at the opening of the elevator car, and their automatic opening and closing are controlled by a drive mechanism. To prevent any swaying during the opening and closing process, a strip-shaped groove is provided at the bottom of the elevator car opening. The bottom of the elevator door usually has multiple guide posts that match the strip-shaped groove. When the elevator door opens and closes, the guide posts can only slide along the strip-shaped groove, preventing the elevator door from swaying. However, after prolonged use, the guide posts may become damaged, such as becoming severely worn or unable to rotate. With the current elevator door structure, replacing the guide posts requires removing the entire elevator door for replacement, which is time-consuming and labor-intensive, necessitating improvement. Utility Model Content

[0003] To address the aforementioned shortcomings of the prior art, this application provides an elevator door structure that allows for the replacement of the guide column at the bottom of the elevator door without removing the elevator door, thereby improving replacement efficiency.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] An elevator door structure, comprising:

[0006] The door panel has vertical plates symmetrically arranged at both ends. One end of the vertical plate protrudes from one side of the door panel and has a bent section that bends 90 degrees inward toward the door panel. The inner side of the bent section is provided with a notch extending to the vertical plate. A reinforcing rib is provided between a pair of vertical plates, and the reinforcing rib is located above the notch. A first limiting piece is vertically provided at the bottom of the inner side of each vertical plate.

[0007] The fixing rod is horizontally positioned above a pair of first limiting plates and below the notch. The two sides of the fixing rod abut against the door panel and the bent section, respectively. The bottom of the fixing rod is rotatably connected to multiple guide posts along the length direction. The height of the fixing rod is greater than the length of the notch.

[0008] A baffle, located between a pair of vertical plates, is used to cover the reinforcing ribs and fixing rods. Both ends of the baffle have protrusions that match the notches, and the protrusions are located inside the notches. A pressure plate is provided on the inner side of the baffle, and the pressure plate abuts against the top of the fixing rod.

[0009] Furthermore, the baffle includes a first baffle and a second baffle, the second baffle is located above the first baffle, the protrusions are located at the top of both ends of the first baffle, and the first baffle is connected to the fixing rod by screws.

[0010] Furthermore, the first baffle includes an upper section and a lower section, both of which are rectangular in shape. The thickness of the lower section matches the thickness of the bent section, and the height of the top of the lower section matches the height of the top of the fixing rod. The thickness of the upper section is greater than the thickness of the bent section, and the inner side of the upper section protrudes beyond the inner side of the lower section. A connecting block is provided at the top of the fixing rod, and a countersunk hole is provided on the outer side of the upper section for accommodating the head of the screw. The screw passes through the countersunk hole and is threadedly connected to the connecting block. The screw is an internal angle screw.

[0011] Furthermore, the tops of multiple guide posts are connected to multiple connecting posts via rotating shafts, and the multiple connecting posts pass through the tops of the fixing rods and are connected to multiple second limiting plates. The bottoms of the second limiting plates abut against the tops of the fixing rods, and the tops of the second limiting plates abut against the pressure plate.

[0012] Furthermore, the diameter of the guide post is less than or equal to the diameter of the connecting post.

[0013] The beneficial effects of this utility model are as follows:

[0014] When replacing the bottom guide column of this elevator door structure, it is not necessary to remove the elevator door from the elevator car. Simply remove the baffle, lift the fixing rod upward to the notch, and then remove the fixing rod and guide column for replacement. This improves the efficiency of guide column replacement.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] This application provides an elevator door structure, such as... Figures 1-5 As shown, it includes door panel 1, fixing rod 2, and baffle.

[0023] Specifically, vertical plates 101 are symmetrically arranged at both ends of the door panel 1. One end of the vertical plate 101 protrudes from one side of the door panel 1, and one end of the vertical plate 101 has a bent section 1011 that bends inward at 90 degrees towards the door panel 1. Notches 1012 extending to the vertical plate 101 are opened on the inner side of the bent section 1011. A reinforcing rib 102 is provided between the pair of vertical plates 101, and the reinforcing rib 102 is located above the notch 1012. A first limiting piece 103 is vertically provided at the bottom of the inner side of the vertical plate 101. A fixing rod 2 is arranged horizontally above the pair of first limiting pieces 103, and the fixing rod 2 is located below the notch 1012. The fixing rod 2 abuts against the door panel 1 and the bent section 1011 on both sides. The bottom of the fixing rod 2 is rotatably connected to multiple guide posts 3 along the length direction. The height of the fixing rod 2 is greater than the length of the notch 1012. A baffle is set between a pair of vertical plates 101 to cover the reinforcing rib 102 and the fixing rod 2. Both ends of the baffle are provided with protrusions 406 that match the notch 1012. The protrusions 406 are located inside the notch 1012. A pressure plate 404 is provided on the inner side of the baffle. The pressure plate 404 abuts against the top of the fixing rod 2. The baffle can be connected to the reinforcing rib 102 and the fixing rod 2 by screws 405.

[0024] When the guide post 3 needs to be replaced, remove the baffle, then lift the fixing rod 2 upward to the notch 1012 to remove the fixing rod 2 and the guide post 3. After replacing the guide post 3 below the fixing rod 2, put the fixing rod 2 back above the first limiting piece 103 from the notch 1012, and then reinstall the baffle to complete the replacement of the guide post 3.

[0025] For details, please refer to Figures 1-3 The baffle includes a first baffle 4 and a second baffle 5. The second baffle 5 is located above the first baffle 4, and the protrusions 406 are located at the top of both ends of the first baffle 4. The first baffle 4 is connected to the fixing rod 2 by screws 405. The second baffle 5 can be welded to a pair of bent sections 1011. When replacing the guide post 3, only the first baffle 4 needs to be removed, and the second baffle 5 does not need to be removed, which further improves the replacement efficiency.

[0026] Preferred options, please refer to Figure 2 , Figure 3The first baffle 4 includes an upper section 402 and a lower section 401, both of which are rectangular. The thickness of the lower section 401 matches the thickness of the bent section 1011, and the top height of the lower section 401 matches the top height of the fixing rod 2. The thickness of the upper section 402 is greater than the thickness of the bend, and the inner side of the upper section 402 protrudes from the inner side of the lower section 401. The top of the fixing rod 2 is provided with a connecting block 201, and the outer side of the upper section 402 is provided with a countersunk hole 403 for accommodating the head of the screw 405. The screw 405 passes through the countersunk hole 403 and is threadedly connected to the connecting block 201. The screw 405 is an internal angle screw 405. Because the sheet metal thickness of the door panel 1 and the vertical plate 101 used to manufacture the elevator is relatively thin, this setting ensures that the first baffle 4 does not protrude beyond the outside of the vertical plate 101 after installation, and allows for the opening of a countersunk hole 403 in the upper section 402 to accommodate the head of the screw 405, thus preventing the head of the screw 405 from protruding beyond the first baffle 4, which would otherwise require a wider door gap to accommodate the elevator door.

[0027] Preferred options, please refer to Figure 4 , Figure 5 Multiple guide posts 3 are connected to multiple connecting posts 302 via rotating shafts. Each connecting post 302 passes through the top of the fixing rod 2 and connects to multiple second limiting plates 301. The bottom of the second limiting plate 301 abuts against the top of the fixing rod 2, and the top of the second limiting plate 301 abuts against the pressure plate 404. Specifically, the diameter of the guide post 3 is less than or equal to the diameter of the connecting post 302. With this design, when replacing the guide post 3, it is not necessary to remove the fixing rod 2; simply lift the second limiting plates 301, connecting posts 302, and guide posts 3 upwards to detach them from the fixing rod 2.

[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
