specific implementation plan

The present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

A wire rope lock provided by the present invention, as shown in Figure 1-3, includes a lock body 4, a push-pull electromagnet 1, a one-way lock head 4, a push rod 8, a small arm 5, a large arm 6, a torsion spring 10, steel wire rope 3 and power supply 11, push-pull type electromagnet 1 comprises push-pull rod 9, electromagnet 12 and tower spring 2, electromagnet 12, one-way lock head 7, torsion spring 10 and power supply 11 are fixedly arranged on lock body 4, The small arm 5 and the big arm 6 are respectively connected with the lock body 4 by a rotating pair, the push rod 8 is connected with the one-way lock head 7 by a moving pair, the push-pull rod 9 is connected with the electromagnet 12 by a moving pair, and the wire rope 3 is fixed at one end It is arranged on the lock body 4, and the other end enters the wire rope through hole and the one-way lock head 7 from one side of the lock body 4 and protrudes from the other side.

Connect power supply 11, push-pull type electromagnet 1 is energized, and push-pull bar 9 retracts, promptly moves to the right, and because of the elastic force of tower spring 2 after power failure, push-pull bar 9 stretches out, promptly moves to the left. The push-pull electromagnet 1 is energized and de-energized, which can drive the small arm 5 to rotate a certain angle on the lock body 4. The small arm 5 and the large arm 6 are in contact with the hook structure, and the large arm 6 is due to the elastic force of the torsion spring 10. And produce the trend that turns counterclockwise, the rotation of big arm 6 promotes the left movement of push rod 8, and push rod 8 moves left and opens one-way lock 7, and steel rope 3 can be pulled bidirectionally.

The installation process of the present invention is as follows: a kind of wire rope lock provided by the present invention, electromagnet 12, one-way lock head 7, torsion spring 10 and power supply 11 are fixedly installed on the lock body 4, with bolt or bearing pin as rotating shaft, The small arm 5 and the large arm 6 are installed on the lock body 4 so that the small arm 5 and the large arm 6 can only rotate at a certain angle on the lock body 4 . The push rod 8 is installed in the key opening hole of the one-way lock head 7, so that the push rod 8 can only move in the key opening hole of the one-way lock head 7, and the push-pull rod 9 is installed on the electromagnet 12, so that the electromagnet 12 is energized. And power-off driving push-pull rod 9 stretches out and retracts. Wire rope 3 one ends are fixedly installed on the lock body 4, and after the other end passes through the wire rope hole on the left side of the lock body 4, enters from another wire rope hole on the left side, and then enters from the steel wire penetration hole on the left side of the one-way lock head 7, Pass through the steel wire hole on the right side of the one-way lock head 7, and finally pass through the steel wire hole on the right side of the lock body 4.

The working process of the present invention is as follows, as shown in Figure 2, the power supply 11 is switched on, and the push-pull electromagnet 1 is energized, so that the push-pull rod 9 is retracted, that is, moved to the right, and the small arm 5 is driven to rotate clockwise around the rotation point, and rotates to After a certain angle, the small arm 5 is out of contact with the large arm 6, and the large arm 6 rotates counterclockwise under the elastic force of the torsion spring 10, so that the large arm 6 drives the ejector rod 8 to move, and the ejector rod 8 moves to the left to open the one-way lock Head 7, steel wire rope 3 can pull bidirectionally.

As shown in Figure 3, after the push-pull electromagnet 1 is de-energized, due to the elastic force of the tower spring 2, the push-pull rod 9 stretches out, that is, moves to the left, and drives the small arm 5 to rotate counterclockwise around the rotation point and return to the initial position. And the big arm 6 can't return to the initial position due to the elastic force of the torsion spring 10 . Now the one-way lock 7 is in the open state, and the steel wire rope 3 can be pulled bidirectionally. Manually push the boom 6 upwards so that the forearm 5 contacts the boom 6 again, and the locking is completed.

A is the locked area of the article. The first step is to put the wire rope lock in the unlocked state, and the wire rope 3 can be pulled in both directions to bind and lock the article with the wire rope 3; the second step is to manually push the arm 6 upward to complete the lock. Because the one-way lock head 7 is in the locked state at the time, the steel wire rope 3 can only be pulled to the right, and cannot be pulled to the left, and the steel wire rope 3 is pulled to the right so that the article is locked; The push-pull electromagnet 1 is energized, the push-pull rod 9 is retracted, the small arm 5 rotates clockwise, and is out of contact with the large arm 6, the large arm 6 rotates counterclockwise, drives the ejector rod 8 to move to the left, and opens the one-way lock 7 , The wire rope 3 can be pulled in both directions, so that the items are taken out.

The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, those skilled in the art may make various modifications and improvements to the present invention. All should expand in the scope of protection as defined in the claims of the present invention.
