DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, in the first embodiment, a movable hook for facilitating lifting operations comprises: a first locking hook 1, a second locking hook 2, a hanging plate 3, a first pushing block 4, a second pushing block 5 and a locking assembly 6;

[0022] A hanging hole is provided at the top of the hanging plate 3, and a slide groove 3.1 is provided inside the hanging plate 3. The slide groove 3.1 is in an inverted T shape, and the slide groove 3.1 includes a horizontal groove 3.11 and a vertical groove 3.12. The hook tails of the first lock hook 1 and the second lock hook 2 are rotatably installed at the bottom end of the hanging plate 3, and the hook tips of the first lock hook 1 and the second lock hook 2 are opposite to each other. The first push block 4 is arranged on the side of the first lock hook 1 opposite to the second lock hook 2, and the second push block 5 is arranged on the side of the second lock hook 2 opposite to the first lock hook 1. A limiting hole 5.1 is provided at the end of the second push block 5, and the locking assembly 6 is slidably arranged in the hanging plate 3.

[0023] When the device is needed to be used to hoist an object, the traction rope is first fixed in the hanging hole, and then the first lock hook 1 and the second lock hook 2 are opened in opposite directions so that the object is placed between the first lock hook 1 and the second lock hook 2.

[0024] Then the lifting is carried out. During the lifting process, the first locking hook 1 and the second locking hook 2 respectively hook the two sides of the object. When the object is suspended in the air, the hanging plate 3 rotates to a vertical state. At this time, the first push block 4 pushes the locking assembly 6 toward the second push block 5, and inserts the locking assembly 6 into the limiting hole 5.1, thereby realizing the mutual locking between the first locking hook 1, the second locking hook 2 and the hanging plate 3, so that the shaking of the object during lifting cannot unlock the first locking hook 1 and the second locking hook 2, thereby realizing a more stable lifting operation.

[0025] The locking assembly 6 includes a locking rod 6.1, a connecting rod 6.2 and a slider 6.3. The bottom end of the connecting rod 6.2 is fixedly connected to the locking rod 6.1, and the locking rod 6.1 and the connecting rod 6.2 are perpendicular to each other. The top end of the connecting rod 6.2 is fixedly connected to the slider 6.3, and the slider 6.3 and the locking rod 6.1 are perpendicular to each other. The locking rod 6.1 is slidably installed in the transverse groove 3.11, and the length of the locking rod 6.1 is greater than the length of the transverse groove 3.11. The connecting rod 6.2 is slidably installed in the longitudinal groove 3.12, and the locking rod 6.1 can be inserted into the limiting hole 5.1.

[0026] When the first push block 4 pushes the locking assembly 6, the first push block 4 first contacts the locking rod 6.1, and the first push block 4 pushes the locking rod 6.1 toward the second lock hook 2. The locking rod 6.1 slides inside the transverse groove 3.11, driving the connecting rod 6.2 to slide inside the longitudinal groove 3.12, and the connecting rod 6.2 drives the slider 6.3 to slide inside the through groove 3.2. When the locking rod 6.1 is pushed to the farthest distance by the push block, the locking rod 6.1 is inserted into the limiting hole 5.1 toward one end of the second lock hook 2, thereby achieving the mutual locking effect between the first lock hook 1, the second lock hook 2 and the suspension plate 3.

[0027] The first push block 4 is fixedly installed with the first lock hook 1, and the second push block 5 is fixedly installed with the second lock hook 2. The ends of the first push block 4 and the second push block 5 are in contact with the outer wall of the bottom end of the suspension plate 3. A through groove 3.2- is provided at the top of the slide groove 3.1. The length of the through groove 3.2- is adapted to the width of the vertical groove. The slider 6.3 is slidably installed in the through groove 3.2-. A limit block 7 is fixedly installed on the bottom end of the suspension plate 3 facing the first push block 4, and the limit block is adapted to the first push block 4.

[0028] When hoisting an object, first manually slide the slider 6.3 to one side of the through slot 3.2, so that the end of the locking rod 6.1 toward the first push block 4 passes through the transverse slot 3.11, and the end of the locking rod 6.1 toward the second push block 5 enters the transverse slot 3.11, and then the first locking hook 1 and the second locking hook 2 are hooked on both sides of the object respectively. When the object is suspended in the air, the hanging plate 3 rotates to a vertical state. At this time, the first locking hook 1 and the second locking hook 2 are in a symmetrical state, and the limit block 7 is in contact with the surface of the first locking hook 1 to prevent the first locking hook 1 from rotating too much and failing to achieve gravity self-locking;

[0029] The limiting hole 5.1 corresponds to the locking rod 6.1. When the push block moves on the surface of the bottom end of the hanging plate 3, the end of the locking rod 6.1 facing the first push block 4 is pushed into the inside of the transverse groove 3.11, and the end of the locking rod 6.1 facing the second push block 5 is inserted into the limiting hole 5.1, so as to achieve the effect of mutual locking between the first locking hook 1, the second locking hook 2 and the hanging plate 3;

[0030] After the lifting is completed, the object is pulled out horizontally between the first locking hook 1 and the second locking hook 2, and then the first locking hook 1 is rotated downward so that the end of the first push block 4 is away from the end of the locking rod 6.1, and the slider 6.3 is moved to reset the slider 6.3 and unlock the second locking hook 2 and the suspension plate 3.

[0031] like Figure 3 and Figure 4 As shown, in the second embodiment, the first push block 4 is slidably connected to the first lock hook 1, the second push block 5 is slidably connected to the second lock hook 2, and the first push block 4 and the second push block 5 are fixedly installed with a spring 10 at one end away from the hanging plate 3, and the other ends of the two springs 10 are fixedly installed on the first lock hook 1 and the second lock hook 2 respectively.

[0032] When the first lock hook 1 and the second lock hook 2 rotate, the initial state of the spring 10 is an extended state, so that the ends of the first push block 4 and the second push block 5 are in close contact with the bottom surface of the suspension plate 3.

[0033] A limiting groove 8 is provided at the opposite end of the first lock hook 1 and the second lock hook 2, and a limiting block 2 9 is fixedly installed on the side of the first push block 4 that is in close contact with the first lock hook 1 and the side of the second push block 5 that is in close contact with the second lock hook 2. The limiting block 2 9 is slidably installed in the limiting groove 8.

[0034] When the first lock hook 1 and the second lock hook 2 rotate, the limit block clamps the limit block 2 9, so that the first push block 4 is displaced along the rotation direction of the first lock hook 1. The first push block 4 is displaced along the rotation direction of the first lock hook 1. If the spring 10 is squeezed, the limit block 2 9 can slide inside the limit groove 8.

[0035] A groove 11 is provided at the bottom end of the hanging plate 3 toward the first locking hook 1, and the first push block 4 can be inserted into the groove 11. A groove 2 12 is connected to the side of the groove 11, and the first push block 4 can be inserted into the groove 2 12. A groove 3 13 is provided at the bottom end of the hanging plate 3 toward the second locking hook 2, and the second push block 5 can be inserted into the third groove. The groove 2 12 and the groove 3 13 are connected through the transverse groove 3.11.

[0036] In the initial state, the first push block 4 is inserted into the second groove 12, so that the first lock hook 1 and the hanging plate 3 are fixedly connected, and the second push block 5 moves on the bottom surface of the hanging plate 3, hooks the first lock hook 1 on one end of the object, and then bends the second lock hook 2 so that the second lock hook 2 hooks the other end of the object. When the second lock hook 2 rotates, the second push block 5 is closely attached to the bottom surface of the hanging plate 3, and when passing through the third groove 13, the second push block 5 is inserted into the third groove;

[0037] When the object is in a suspended state, the suspension plate 3 rotates to a vertical state. At this time, the first push block 4 disengages from the groove 11, and when the groove 12 rotates to correspond to the first push block 4, the first push block 4 is inserted into the groove 2 12 by the force of the spring 10, thereby realizing the overall locking of the device.

[0038] A through slot 3.2 is provided at the top of the slide slot 3.1, the length of which is greater than the width of the vertical slot, the slider 6.3 is slidably installed in the through slot 3.2, a spring 14 is provided between the through slot 3.2 and the slider 6.3, the two ends of the spring 14 are respectively fixedly connected to the slider 6.3 and the side wall of the through slot 3.2, when the locking rod 6.1 is displaced to the maximum distance, the end of the locking rod 6.1 is tangent to the bottom surface of the suspension plate 3.

[0039] When the second push block 5 is inserted into the groove three 13, the locking rod 6.1 is pushed toward the groove two 12 direction, so that the locking rod 6.1 passes through the groove two 12 toward the one end of the first push block 4 and stretches the spring. When the first push block 4 enters the groove two 12, the part of the locking rod 6.1 passing through the groove two 12 is pushed back into the groove two 12, so that the locking rod 6.1 is inserted into the limiting hole 5.1 toward the one end of the second push block 5, and the locking rod 6.1 is blocked by the end of the first push block 4 and cannot pass through the groove two 12, thereby achieving the mutual locking effect between the first locking hook 1, the second locking hook 2 and the suspension plate 3.

[0040] An inclined surface 11.1 is provided between the groove 11 and the groove 2 12, and an inclined surface 13.1 is provided on both sides of the groove 3 13.

[0041] When the suspension plate 3 switches from the initial state to the vertical state, the first push block 4 is subjected to the squeezing force of the inclined surface 11.1, so that the spring 10 is compressed and can be disengaged from the groove 11, and when corresponding to the groove 2 12, the spring is reset to insert the first push block 4 into the groove 2 12, and the second push block 5 is subjected to the squeezing force of the inclined surface 13.1, so that the spring 10 is compressed and can be disengaged from the two sides of the groove 3 13, preventing the second push block 5 from locking when entering the groove 3 13, causing the first lock hook 1 and the second lock hook 2 to be unable to be used normally.

[0042] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
