Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an auxiliary locking structure for an elevator door panel. Background Art

[0002] An elevator is a type of transportation equipment that transports people or goods vertically.

[0003] The elevator is mainly composed of a machine room, a hoistway and pit, a car, and a landing station. When the elevator reaches a floor, the door panels on the outside will automatically open to ensure the normal entry and exit of pedestrians. When it continues to travel up and down, the door panels will automatically close to ensure the closure of the elevator shaft, thereby achieving stability and safety during the operation of the device. However, when the existing door panels are closed, when the outside is hit, due to the single structure of the locking part of the device, the door panels are easily passively opened and leak out of the elevator shaft, causing a safety impact on pedestrians on the outside and affecting its stability when closed.

[0004] Therefore, we provide an auxiliary locking structure for an elevator door panel. Utility Model Content

A telescopic component 7 is arranged below the clamping column 12. When the device is running, when the two supporting door panels 1 are closed, the plug-in bolt 4 inside one of the supporting door panels 1 is moved to the plug-in slot 17 on one side of the other supporting door panel 1. When the plug-in bolt 4 enters the plug-in slot 17, the plug-in bolt 4 will push the clamping column 12 to rotate on the rotating column 1. When the locking cam 12 is in the closed position, the locking cam 12 is in the closed position, and the locking cam 12 is in the closed position, so that ...

[0026] like Figure 1-Figure 4 As shown, a support base plate 16 is provided between the clamping column 12 and the telescopic component 7, the telescopic component 7 is fixedly arranged at the lower end of the telescopic component 7, the clamping column 12 is plugged into the support base plate 16, and the support base plate 16 is slidably arranged inside the plug-in groove 17, and the stability of the position when the clamping column 12 drives the support base plate 16 to slide synchronously is ensured under the support of the plug-in groove 17, and by setting the inside of the support base plate 16 to an inclined structure with a certain angle, when the clamping column 12 rotates, it can drive the support base plate 16 to move downward, thereby achieving the effect of pressing down the telescopic component 7 to compress the telescopic component 7, and by setting the telescopic component 7 to a structure with a spring on the outside and a telescopic rod on the inside, the telescopic component 7 can be stable and reliable when telescopically moving.

[0027] like Figure 1-Figure 4As shown, a dynamic lock hook 2 is arranged above the supporting door panel 1, and a connecting rope 3 is fixedly connected to the lower end of the dynamic lock hook 2. The connecting rope 3 is plugged into the plug bolt 4, and the connecting rope 3 extends to the inside of the plug bolt 4. The side of the connecting rope 3 away from the dynamic lock hook 2 is fixedly connected to a movable connecting frame 8. By moving the existing dynamic lock hook 2 in the device upward, it can drive the connecting rope 3 below to move while contacting its existing locking component, thereby driving the movable connecting frame 8 inside the plug bolt 4 to move, providing support for the release of the limiting component.

[0028] Embodiment 2: An auxiliary locking structure for an elevator door panel, such as Figure 1-Figure 4 As shown, a support rod 5 is fixedly provided inside the plug bolt 4, and a moving block 6 is inserted on one side of the support rod 5. The moving block 6 extends out of the outside of the support rod 5, and the moving block 6 is located above the clamping groove 11. A telescopic component 7 is fixedly provided on the upper end of the moving block 6, and the upper end of the telescopic component 7 is fixedly provided on one side of the inside of the plug bolt 4. By moving the support rod 5 of the moving block 6 downward under the limit, it is moved into the clamping groove 11, so that the clamping part inside it is pressed to move it into the clamping groove 11, thereby releasing the clamping effect at the same time, so that the plug bolt 4 can be unlocked at the same time as the door lock is opened, ensuring the normal opening and closing of the device, and by setting the initial state of the telescopic component 7 to normal, the moving block 6 will pull the telescopic component 7 to stretch when it moves down, and the moving block 6 can be driven to reset and move under the reset elasticity of the telescopic component 7.

[0029] like Figure 1-Figure 4 As shown, the mobile connecting frame 8 is plugged into the telescopic assembly 7, and at least two mobile rings 9 are arranged at the lower end of the mobile connecting frame 8. The mobile ring 9 is slidably connected to the limit strip 10, and the limit strip 10 is fixedly arranged on the outside of the support rod 5. The moving block 6 is located between the two mobile rings 9. The mobile ring 9 is moved under the limit guide of the support rod 5 and the multiple limit strips 10 on the outside thereof. The movement of the two mobile rings 9 can simultaneously drive the mobile connecting frame 8 above it to be displaced, so that the moving block 6 can be continuously pressed down through the inclined structure of the mobile connecting frame 8, so that it can move the lower limit component, and after the pulling component on one side of the mobile connecting frame 8 becomes loose, the moving block 6 can drive the mobile connecting frame 8 to move to the other side when it automatically resets upward, thereby ensuring its stability and reliability during the next movement.

[0030] Working principle: When the two supporting door panels 1 are closed, the plug bolt 4 inside one of the supporting door panels 1 is moved into the plug slot 17 on one side of the other supporting door panel 1. When the plug bolt 4 enters the plug slot 17, the plug bolt 4 will push the clamping column 12 to tilt under the rotation support of the rotating column 14, so that the plug bolt 4 continues to move inward. When the clamping slot 11 below the plug bolt 4 moves and intersects with the clamping column 12, the pressure on the clamping column 12 disappears, so that the telescopic component 7 below it rebounds after compression, thereby achieving the effect of clamping the clamping column 12 in the clamping slot 11. The plug bolt 4 is restricted inside the plug slot 17, so as to achieve the effect of closing and limiting the two supporting door panels 1. Therefore, by further closing and locking the two supporting door panels 1 on the basis of the original locking of the device, the closing of the device can be auxiliary locked, thereby improving the stability of the device when closed. In addition, by the support of the plug slot 17 and the limitation of the limit block 15, the angle stability of the card column 12 when it is rotated and the firmness of the card locking are guaranteed. In addition, by setting the movable mouth 13 to be able to slide a short distance under the limitation of the rotating column 14, the convenience and stability of the card column 12 when it is released from the limit can be guaranteed.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
