[0018] 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.

[0019] Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a novel turnout hook lock device, including a screw 1, a screw block 10 threaded on the outer surface of the screw 1, a locking pin 2 rotatably connected to the top of the screw block 10, a sliding hole opened on the top of the locking pin 2, the inner wall of the sliding hole slidingly connected to the outer surface of the screw 1, a support block 4 fixedly connected to one side of the screw block 10, a rotating plate 5 rotatably provided on the inner wall of the two support blocks 4, a locking piece 3 fixedly connected to the top of the screw 1, a limiting groove 11 opened on one side of the screw 1, a limiting block 12 slidably connected to the inner wall of the limiting groove 11, and one side of the limiting block 12 fixedly connected to the inner wall of the sliding hole;

[0021] Through the above embodiments, the locking pin 2 can be limited by the limiting groove 11 and the limiting block 12. Therefore, when the screw block 10 rotates, it will not drive the locking pin 2 to rotate, so that the angle of the locking pin 2 is always aligned with the locking piece 3. The rotating plate 5 can rotate, and the angle of the rotating plate 5 can be laterally, which can conveniently drive the screw block 10 to rotate. This makes it easier to control the rotation of the screw block 10 on the outer surface of the screw 1, so that the screw block 10 can move along the direction of the screw 1, thereby driving the locking pin 2 to move, which makes it easier to adjust the distance between the locking pin 2 and the locking piece 3.

[0022] A rotating groove 7 is provided on one side of the support block 4, and a rotating rod 8 is rotatably connected to the inner wall of the rotating groove 7;

[0023] One end of the rotating rod 8 is fixedly connected to one side of the rotating plate 5. A torsion spring 9 is provided on the outer surface of the rotating rod 8. One end of the torsion spring 9 is fixedly connected to the inner wall of the rotating groove 7, and the other end of the torsion spring 9 is fixedly connected to one side of the rotating plate 5.

[0024] Through the above embodiments, the elastic potential energy provided by the torsion spring 9 enables the rotating plate 5 to have a force that rotates towards the screw 1, thereby enabling the rotating plate 5 to contact the screw 1 without being affected by other external forces, thus preventing the rotating plate 5 from moving arbitrarily and causing inconvenience in the use of the device.

[0025] A limiting plate 6 is fixedly connected to one side of the rotating plate 5, and one side of the limiting plate 6 is adapted to the outer surface of the screw 1.

[0026] Through the above embodiments, the limiting plate 6 enables the rotating plate 5 and the screw 1 to be in a parallel state, thereby better controlling the screw 1 and the rotating plate 5 to drive the locking plate 3 and the locking pin 2 to move, increasing the overall convenience.

[0027] Working principle:

[0028] like Figures 1-4 As shown, during use, the locking pin 2 can be limited by the limiting groove 11 and the limiting block 12. Therefore, when the screw block 10 rotates, it will not drive the locking pin 2 to rotate, so that the angle of the locking pin 2 is always aligned with the locking piece 3. Rotating the rotating plate 5 can drive the screw block 10 to rotate through the support block 4, thus facilitating the rotation of the screw block 10. The screw block 10 rotates on the outer surface of the screw rod 1. Through the limiting of the screw rod 1, the screw block 10 can move along the direction of the screw rod 1, so that the locking pin 2 can be moved through the rotating plate 5, thus facilitating the adjustment of the distance between the locking pin 2 and the locking piece 3. The elastic potential energy provided by the torsion spring 9 can give the rotating plate 5 a force to rotate towards the screw rod 1, so that the rotating plate 5 can be tightly attached to the outer surface of the screw rod 1 through the limiting plate 6 without the action of other external forces, thus better controlling the movement of the screw rod 1 and the rotating plate 5 to drive the locking piece 3 and the locking pin 2.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
