Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the specific embodiments. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The embodiment, as shown in fig. 1 and 2, a novel unhooking prevention device, including two parallel arrangement's backup pad 1 and rotation connection and being in lifting hook 2 between the backup pad 1, lifting hook 2 includes rotation portion 21, connecting portion 22 and colludes claw portion 23 in proper order, rotation portion 21 rotates to be connected in backup pad 1, connecting portion 22 rotates and is connected with the pawl, the one end of pawl is rotor 3 that is parallel to each other, separation blade 4 that the other end is, on the pawl rotor 3 rotates to be connected in on connecting portion 22, arc wall 31 has been seted up on rotor 3, connecting portion 22 side perpendicular fixedly connected with an inserted bar 32, inserted bar 32 activity is pegged graft in the arc wall 31. The utility model discloses can solve 2 line lifting hook and hang the problem that the in-process unhook appears, the utility model discloses in through be provided with on lifting hook 2 can take place to rotate the pawl along with the rotation of lifting hook 2, when the suspension joint object, separation blade 4 on the pawl can with collude the tip coincidence of claw 23, avoid the object to drop, simultaneously, because the action of gravity of heavy object, lifting rope class object is unable to push separation blade 4 open on the lifting hook 2, consequently, the utility model discloses can have the technological effect who prevents 2 unhooks of lifting hook.

As shown in fig. 3, 4 and 5, a pull rod 51 is disposed outside the rotating portion 21, a support rod 51 is disposed at the upper end of the support plate 1, and a spring 5 is connected between the pull rod 51 and the support rod 51. Spring 5's setting can make 2 automatic drops of lifting hook, when the object on lifting hook 2 was placed at support body or subaerial, can make 2 on the lifting hook collude claw portion 23 and lost the decurrent pulling force, the stretched spring 5 of object can further shrink this moment, thereby further drive the rotation portion 21 on the lifting hook 2 and take place to rotate, collude claw portion 23 and be in the state of slope, collude claw portion 23 and just can follow the rings on the object and shift out, lifting hook 2 breaks away from with the object, need not the manual work and again get the hook on the object, transfer efficiency can be improved.

As shown in fig. 3, 4 and 5, the direction of the strut is opposite to the direction of the claw portion 23. When the end of the hook portion 23 is overlapped with the catch 4, the connecting portion 22 is in a vertical state, and the spring 5 is in a stretched state. When the object hangs and connects on lifting hook 2, because the action of gravity, lifting hook 2 can take place to rotate, and inserted bar 32 on connecting portion 22 can move along arc groove 31 on rotor plate 3 this moment, because the rotation orbit of inserted bar 32 is fixed, can drive rotor plate 3 this moment and take place to rotate, makes separation blade 4 on the rotor plate 3 move to with collude the tip coincidence of claw portion 23, the completion colludes claw portion 23 open-ended closure.

As shown in fig. 3, 4 and 5, a contact plate 41 is connected between the two blocking pieces 4, and when the connecting portion 22 is in a vertical state, the contact plate 41 abuts against the end of the hook portion 23. The contact plate 41 is provided to avoid the problem that the opening of the hook part 23 is not completely closed and unhooked, because the contact plate 41 can play a role of blocking when the hook part 23 hooks a steel rope object.

The utility model provides a novel mousing-hook device's theory of operation: when an object is hung on the lifting hook 2, the lifting hook 2 can rotate under the action of gravity, the inserted rod 32 on the connecting part 22 can move along the arc-shaped groove 31 on the rotating piece 3 at the moment, the rotating piece 3 can be driven to rotate at the moment due to the fact that the rotating track of the inserted rod 32 is fixed, the blocking piece 4 on the rotating piece 3 can move to be overlapped with the end part of the hook part 23, and the opening of the hook part 23 is closed; the utility model discloses can have the technological effect that prevents 2 unhookings of lifting hook.
