[0002] An elevator door operator is a mechanism responsible for opening and closing elevator hall and car doors. When it receives an elevator door opening or closing signal, the elevator door operator controls the door opening motor through its own control system, converting the torque generated by the motor into a force in a specific direction. This force then drives the elevator hall and car doors to close or open through the transmission connecting arm assembly connected to the door operator's transmission belt.

[0003] For example, in the announcement number CN212425071U, there is a transmission connecting arm assembly for an elevator door operator drive belt. This utility model can increase the connection range between the connecting arm and the hanging plate through the cooperation of clips, slots and plugs. On the one hand, it reduces the number of screws used and simplifies the cumbersome connection method between the connecting arm and the hanging plate, making the connection between the connecting arm and the hanging plate simpler and more convenient, saving time and effort in installation or disassembly. On the other hand, it improves the stability of the connection between the connecting arm and the hanging plate.

[0004] When assembling the transmission connecting arm assembly in the above scheme, two sets of clips and plugs need to be engaged and connected. Then, bolts are passed through the connecting arm and scraper, and the nuts and bolts are rotated to perform threaded transmission to fix the clips and plugs. However, only one set of bolts is provided for fixing, and it is located at the end of the connecting arm. This can easily lead to uneven force on the transmission connecting arm assembly during fixing, resulting in poor fixing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a transmission connecting arm assembly for an elevator door operator drive belt, so as to solve the problem of poor fixing effect of existing transmission connecting arm assemblies for elevator door operator drive belts mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transmission connecting arm assembly for an elevator door operator's drive belt, comprising: a connecting arm body and a locking mechanism, wherein one end of the connecting arm body is connected to a belt clamp, and one side of the mounting plate is movably connected to a conveyor wheel via a rotating shaft.

[0007] A locking component is fixedly connected to one side of the connecting arm body. The locking component has a slot inside, which engages with a plug. A threaded rod is threadedly connected inside the connecting arm body. A vertical plate is movably connected to the outside of the threaded rod via a bearing. Limiting rods are fixedly connected to both ends of the vertical plate. The outer side of the limiting rod is slidably connected to the connecting arm body. One end of the limiting rod is inserted into a hanging plate. A through hole matching the limiting rod is opened inside the hanging plate. Two sets of locking components and slots are provided, and the two sets of locking components and slots are symmetrically distributed about the central axis of the threaded rod. A locking mechanism is provided at one end of the threaded rod.

[0008] Preferably, one side of the plug is fixedly connected to the mounting plate, and the plug is L-shaped.

[0009] Preferably, the engaging mechanism includes a handle that is slidably connected to the outside of the threaded rod, and a limit block is fixedly connected to one end of the threaded rod.

[0010] Preferably, the handle has a rotating groove a at its end, and the rotating groove a is movably connected to the threaded rod; the handle has a rotating groove b inside, and the rotating groove b is movably connected to the threaded rod.

[0011] Preferably, one end of the rotating groove b is provided with a limiting groove, which is opened inside the handle, and both the rotating groove a and the rotating groove b are cylindrical in shape.

[0012] Preferably, both the limiting groove and the limiting block are rectangular in shape, and the size of the limiting groove is slightly larger than that of the limiting block. A spring is fixedly connected to one side of the limiting block.

[0013] Preferably, one end of the spring is fixedly connected to a rotating block, and one side of the rotating block is movably connected to the handle via a rotating shaft.

[0014] Compared with existing technologies, the beneficial effects of this elevator door operator drive belt transmission connecting arm assembly are as follows: When assembling the connecting arm body and the mounting plate, the two sets of inserts on one side of the mounting plate are inserted into the slots inside the clips on one side of the connecting arm body. After insertion, the handle in the engagement mechanism can be pushed. When the handle moves, it will compress the spring. The handle can rotate when it moves. When the limiting groove inside the handle is aligned with the limiting block at the end of the threaded rod, the two will engage. At this time, the handle can be rotated to drive the threaded rod and the connecting arm body to perform threaded transmission, which drives the vertical plate to move. The vertical plate will drive the limiting rods at both ends to slide in the connecting arm body and gradually insert the ends into the two sets of through holes inside the mounting plate, completing the connection between the connecting arm body and the mounting plate. In this way, the transmission connecting arm assembly can be stably assembled through the above operation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a transmission connecting arm assembly for an elevator door operator's drive belt, comprising: a connecting arm body 1 and a locking mechanism 12, wherein one end of the connecting arm body 1 is connected to a belt clip 2, and one side of the hanging plate 3 is movably connected to a conveyor wheel 4 via a rotating shaft.

[0022] A clip 5 is fixedly connected to one side of the connecting arm body 1. The clip 5 has a slot 6 inside, and the slot 6 is engaged with the plug 7. A threaded rod 8 is threadedly connected inside the connecting arm body 1. A vertical plate 9 is movably connected to the outside of the threaded rod 8 through a bearing. Limiting rods 10 are fixedly connected to both ends of the vertical plate 9. The outer side of the limiting rod 10 is slidably connected to the connecting arm body 1. One end of the limiting rod 10 is inserted into the hanging plate 3. A through hole 11 matching the limiting rod 10 is opened inside the hanging plate 3. Two sets of clips 5 and slots 6 are provided, and the two sets of clips 5 and slots 6 are symmetrically distributed about the central axis of the threaded rod 8. A locking mechanism 12 is provided at one end of the threaded rod 8.

[0023] One side of the plug 7 is fixedly connected to the hanging plate 3. The plug 7 is L-shaped. The connecting arm body 1 and the threaded rod 8 form a threaded transmission structure, and the connecting arm body 1 and the limiting rod 10 form a sliding structure. The engaging mechanism 12 includes a handle 121 that is slidably connected to the outside of the threaded rod 8. One end of the threaded rod 8 is fixedly connected to a limiting block 122. The end of the handle 121 has a rotating groove a123, and the rotating groove a123 is movably connected to the threaded rod 8. The inside of the handle 121 has a rotating groove b124, and the rotating groove b124 is movably connected to the threaded rod 8. One end of groove b124 is provided with a limiting groove 125, which is opened inside the handle 121. The rotating groove a123 and the rotating groove b124 are both cylindrical. The limiting groove 125 and the limiting block 122 are both rectangular, and the size of the limiting groove 125 is slightly larger than that of the limiting block 122. A spring 126 is fixedly connected to one side of the limiting block 122. A rotating block 127 is fixedly connected to one end of the spring 126. One side of the rotating block 127 is movably connected to the handle 121 through a rotating shaft. The handle 121, the rotating groove a123 and the threaded rod 8 form a sliding structure.

[0024] In specific implementation, when assembling the connecting arm body 1 and the hanging plate 3, the transmission connecting arm assembly of the elevator door operator conveyor belt is achieved by inserting two sets of plugs 7 on one side of the hanging plate 3 into the slots 6 inside the clamping parts 5 on one side of the connecting arm body 1. After insertion, the handle 121 in the engaging mechanism 12 can be pushed. When the handle 121 moves, it will compress the spring 126. The handle 121 can rotate when it moves. When the limiting groove 125 inside the handle 121 is aligned with the limiting block 122 at the end of the threaded rod 8, the two will engage. At this time, the handle 121 can be rotated to drive the threaded rod 8 to perform threaded transmission with the connecting arm body 1, which will drive the vertical plate 9 to move. The vertical plate 9 will drive the limiting rods 122 at both ends. The arm 10 slides in the connecting arm body 1 and gradually inserts its end into the two sets of through holes 11 inside the hanging plate 3, completing the connection between the connecting arm body 1 and the hanging plate 3. After the connection is completed, the handle 121 can be released. At this time, the spring 126 can be reset to push the rotating groove b124 to move, so that the limiting groove 125 inside the rotating groove b124 disengages from the locking block 122. At this time, the handle 121 will rotate freely when rotating and will not drive the threaded rod 8 to rotate. This can prevent accidental contact with the handle 121 from causing the limiting rod 10 to disengage from the hanging plate 3. Furthermore, since the rotating block 127 is rotatable, it will not cause the spring 126 to twist. Thus, the above operation can facilitate the stable assembly of the transmission connecting arm assembly.

[0025] In summary: When using the transmission connecting arm assembly of the elevator door operator drive belt, the connecting arm body 1 is first connected to the hanging plate 3, and then the connecting arm body 1 and the hanging plate 3 are fixed by the limiting component to complete the assembly of the transmission connecting arm assembly. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
