[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An elevator synchronous door knife that is easy to install and adjust includes a door knife base plate 1, a quick-release structure 4 installed at the rear end of the door knife base plate 1, and a limit component 3 provided between the quick-release structure 4 and the door knife base plate 1. A support frame 9 is fixedly provided at the front end of the door knife base plate 1, and a rotating plate 10 is rotatably installed inside the support frame 9. Door knife arms 2 are hinged on both the left and right sides of the rotating plate 10. Multiple transmission holes 7 are opened inside the door knife arms 2, and a connection hole 6 is opened at the top of the transmission holes 7.

[0028] The quick-release structure 4 includes a connector 401 fixed to the rear end of the door knife base plate 1. A plug plate 402 is fixedly installed below the connector 401. An installation base 404 is movably installed on the outside of the plug plate 402. A connecting groove 405 is provided at the connection between the installation base 404 and the plug plate 402. Fixing ear plates 5 are welded on both the left and right sides of the installation base 404, and screws pass through the inside of the fixing ear plates 5.

[0029] By adopting the above technical solution, after the mounting base 404 is installed in a suitable position in the car with screws, the door knife base plate 1 is inserted into the interior of the connecting groove 405 through the insert plate 402, so that the connector 401 is snapped into the connecting groove 405. The mounting base 404 and the door knife base plate 1 are interlocked, which facilitates the disassembly and assembly of the door knife base plate 1. When disassembling the door knife base plate 1, simply lift the door knife base plate 1 upwards to disengage the connector 401 from the mounting base 404. The disassembly tooling of the door knife base plate 1 can be realized without the use of screwdrivers, etc., thereby improving the disassembly and assembly efficiency of the door knife base plate 1.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, adjustment holes 403 are provided on both the left and right sides of the connector 401. A movable rod 303 passes through the inner side of the connecting groove 405. A limiting block 302 with a diameter larger than the movable rod 303 is fixedly installed at one end of the movable rod 303, and a limiting plate 301 with a diameter larger than the movable rod 303 is fixedly installed at the other end of the movable rod 303 inside the mounting base 404. A connecting spring 304 is fixedly installed between the limiting block 302 and the mounting base 404, and the movable rod 303 passes through the inside of the connecting spring 304. The size of the limiting block 302 is adapted to the size of the adjustment hole 403. Multiple sets of adjustment holes 403 are provided. The thickness of the connector 401 is greater than the thickness of the insert plate 402.

[0031] The surface of the mounting base 404 is provided with an abutment component 8, which includes a telescopic rod 803 fixed to the surface of the mounting base 404, and an abutment spring 802 is sleeved on the outside of the telescopic rod 803. A rubber plate 801 is fixedly provided at the end of the telescopic rod 803.

[0032] By adopting the above technical solution, multiple sets of adjustment holes 403 are opened on the side of the connector 401. By inserting the limiting component 3 into the adjustment hole 403 at a suitable height, the height of the door knife base plate 1 can be adjusted. During adjustment, it is not necessary to disassemble the mounting base 404. At the same time, the limiting component 3 plays a secondary limiting role for the connector 401, which can prevent the connector 401 from detaching from the mounting base 404. During limiting, under the action of the connecting spring 304, the limiting block 302 moves towards the side wall of the mounting base 404. The connecting spring 304 compresses, causing the connector 401 to be inserted into the mounting base 404. When the adjustment hole 403 at the corresponding position is at the same height as the limiting block 302, the height of the door knife base plate 1 can be adjusted. When the two devices are in sync, the limiting block 302 can be inserted into the adjusting hole 403 under the pushing action of the connecting spring 304, thereby limiting the door knife base plate 1. When the door knife base plate 1 needs to be disassembled, the limiting plate 301 is pulled outward, and the limiting plate 301 can drive the movable rod 303 to retract to the mounting base 404, thereby causing the limiting block 302 to disengage from the adjusting hole 403. At the same time as the door knife base plate 1 is installed, the door knife base plate 1 can abut against the rubber plate 801 and press inward against the spring 802 and the telescopic rod 803 to compensate for the gap between the door knife base plate 1 and the mounting base 404, so as to prevent the door knife base plate 1 from tilting towards the mounting base 404.

[0033] Working principle: After the mounting base 404 is installed in the appropriate position in the car with screws, the door knife base plate 1 is inserted into the connecting groove 405 through the insert plate 402, so that the connector 401 is snapped into the connecting groove 405. The mounting base 404 and the door knife base plate 1 are interlocked, which facilitates the disassembly and assembly of the door knife base plate 1. When disassembling the door knife base plate 1, simply lift the door knife base plate 1 upwards to disengage the connector 401 from the mounting base 404. The disassembly tooling of the door knife base plate 1 can be achieved without the use of screwdrivers, improving the disassembly and assembly efficiency of the door knife base plate 1. Multiple sets of adjustment holes 403 are opened on the side of the connector 401. By inserting the limiting component 3 into the adjustment hole 403 at the appropriate height, the height of the door knife base plate 1 can be adjusted. During adjustment, it is not necessary to disassemble the mounting base 404. At the same time, the limiting component 3 plays a secondary limiting role for the connector 401, which can prevent the connector 401 from disengaging from the mounting base 404. When limiting, the connector 401 is in a position that allows for easy positioning. Under the action of the connecting spring 304, the limiting block 302 moves towards the side wall of the mounting base 404. The connecting spring 304 presses, causing the connecting piece 401 to insert into the mounting base 404. When the height of the corresponding adjustment hole 403 matches that of the limiting block 302, the limiting block 302 can be inserted into the adjustment hole 403 under the pushing action of the connecting spring 304, thereby limiting the door knife base plate 1. When it is necessary to remove the door knife base plate 1, the limiting plate 301 is pulled outward. The limiting plate 301 can drive the movable rod 303 to retract to the mounting base 404, thereby causing the limiting block 302 to disengage from the adjustment hole 403. While the door knife base plate 1 is being installed, the door knife base plate 1 can abut against the rubber plate 801 and press inward against the spring 802 and the telescopic rod 803 to compensate for the gap between the door knife base plate 1 and the mounting base 404, preventing the door knife base plate 1 from tilting towards the mounting base 404.
