Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 1 and 2, the car arrester for a crashproof elevator door of the fourth generation building of the present embodiment includes a base 1, a vertical rod 2, a connecting rod 3, a sliding block 4, a steel wire rope 5, a spring 6 and a limiting mechanism 7. The bottom of pole setting 2 is articulated through first pin 8 with base 1, and slider 4 is through sliding pair connection in base 1, specifically sets up horizontal spout 9 on base 1, and the pin joint of pole setting 2 and base 1 is located the one end of spout 9. The sliding block 4 is arranged in the sliding groove 9 and can slide along the sliding groove 9. One end of the connecting rod 3 is hinged with the middle part of the vertical rod 2 through a second pin 10, and the other end of the connecting rod 3 is hinged with the top of the sliding block 4 through a third pin 11. One end of the sliding block 4 along the sliding direction is connected with a steel wire rope 5. The other end of slider 4 along its slip direction connects spring 6, and spring 6 and base 1 fixed connection, spring 6 are in between pole setting 2 and slider 4, and the flexible direction of spring 6 is on a parallel with the setting of spout 9.

The limiting mechanism 7 is disposed on one side of the sliding groove 9, as shown in fig. 2, the limiting mechanism 7 includes a limiting tongue 701, a limiting sliding groove 702, and a retractable spring 703, and the limiting tongue 701 is in sliding fit with the limiting sliding groove 702. The rear end of the limiting tongue 701 is connected with an expansion spring 703, the expansion spring 703 is fixedly connected with a limiting sliding groove 702, the limiting tongue 701 is made of a magnetic material, the tail end of the limiting sliding groove 702 is provided with an electromagnet 704, the limiting tongue 701 is controlled to be retracted into the limiting sliding groove 702 when the electromagnet 704 is powered on, and the sliding of the sliding block 4 is blocked when the limiting tongue 701 extends out of the limiting sliding groove 702. In order to prevent the vertical rod 1 from being directly pressed down, one side surface of the limiting tongue 701 facing the vertical rod is a plane parallel to the extending direction of the extension spring 703, and the other opposite side surface is an arc surface or an inclined surface.
