Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown in Embodiment 1, a movable hook that facilitates lifting operations includes: a first locking hook 1, a second locking hook 2, a suspension plate 3, a first push block 4, a second push block 5, and a locking assembly 6.

[0022] The top end of the hanging plate 3 is provided with a hanging hole, and the inside of the hanging plate 3 is provided with a sliding groove 3.1, which is inverted T-shaped and includes a horizontal groove 3.11 and a vertical groove 3.12. The hook tails of the first and second hooks 1 and 2 are rotatably installed at the bottom end of the hanging plate 3, and the hook tips of the first and second hooks 1 and 2 are opposite to each other. The first push block 4 is arranged on the side of the first hook 1 opposite to the second hook 2, and the second push block 5 is arranged on the side of the second hook 2 opposite to the first hook 1. The end of the second push block 5 is provided with a limiting hole 5.1, 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, first, the traction rope is fixed in the hanging hole, and then the first and second hooks 1 and 2 are pried open in opposite directions to allow the object to be between the first and second hooks 1 and 2.

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

[0025] The locking assembly 6 includes a locking rod 6.1, a connecting rod 6.2 and a sliding block 6.3. The bottom end of the connecting rod 6.2 is fixedly connected with the locking rod 6.1, and the locking rod 6.1 is perpendicular to the connecting rod 6.2. The top end of the connecting rod 6.2 is fixedly connected with the sliding block 6.3, and the sliding block 6.3 is perpendicular to the locking rod 6.1. The locking rod 6.1 is slidably installed in the horizontal groove 3.11, and the length of the locking rod 6.1 is greater than the length of the horizontal groove 3.11. The connecting rod 6.2 is slidably installed in the vertical groove 3.12. 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, first, the first push block 4 contacts the locking rod 6.1. The first push block 4 pushes the locking rod 6.1 towards the second hook 2. The locking rod 6.1 slides in the horizontal groove 3.11, driving the connecting rod 6.2 to slide in the vertical groove 3.12, and driving the sliding block 6.3 to slide in the through groove 3.2. When the locking rod 6.1 is pushed to the farthest distance by the push block, the end of the locking rod 6.1 towards the second hook 2 is inserted into the limiting hole 5.1, thereby achieving the effect of mutual locking between the first and second hooks 1 and 2 and the hanging plate 3.

[0027] The first push block 4 is fixedly installed with the first locking hook 1, and the second push block 5 is fixedly installed with the second locking hook 2. The end portions of the first push block 4 and the second push block 5 are in contact with the bottom end outer wall of the hanging plate 3. The top end of the sliding groove 3.1 is provided with a through groove 3.2. The length of the through groove 3.2 is adapted to the width of the vertical groove. The sliding block 6.3 is slidingly installed in the through groove 3.2. The bottom end of the hanging plate 3 facing the first push block 4 is fixedly installed with a limiting block 7. The limiting block is adapted to the first push block 4.

[0028] When hoisting the object, first manually slide the sliding block 6.3 to one side of the through groove 3.2, so that one end of the locking rod 6.1 facing the first push block 4 passes through the horizontal groove 3.11, and the other end of the locking rod 6.1 facing the second push block 5 enters the horizontal groove 3.11. Then hook the first locking hook 1 and the second locking hook 2 on both sides of the object. When the object is suspended, the hanging plate 3 rotates to be vertical. At this time, the first locking hook 1 and the second locking hook 2 are in a symmetrical state. The limiting block 7 is in contact with the surface of the first locking hook 1, preventing 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 horizontal groove 3.11, and the other end of the locking rod 6.1 facing the second push block 5 is inserted into the limiting hole 5.1, achieving the mutual locking effect between the first locking hook 1, the second locking hook 2 and the hanging plate 3.

[0030] After hoisting is completed, the first locking hook 1 and the second locking hook 2 are pulled out transversely between the first locking hook 1 and the second locking hook 2. Then the first locking hook 1 is rotated downward, so that the end portion of the first push block 4 is away from the end portion of the locking rod 6.1. The sliding block 6.3 is actuated to reset, and the second locking hook 2 is unlocked from the hanging plate 3.

[0031] As shown in FIGS. 1 and 2, in the first embodiment, the first push block 4 is fixedly installed with the first locking hook 1, and the second push block 5 is fixedly installed with the second locking hook 2. The end portions of the first push block 4 and the second push block 5 are in contact with the bottom end surface of the hanging plate 3. Figure 3 Figure 4 As shown in FIGS. 3 and 4, in the second embodiment, the first push block 4 is slidingly connected with the first locking hook 1, and the second push block 5 is slidingly connected with the second locking hook 2. The end portions of the first push block 4 and the second push block 5 away from the hanging plate 3 are fixedly installed with springs 10. The other ends of the two springs 10 are fixedly installed on the first locking hook 1 and the second locking hook 2 respectively.

[0032] When the first locking hook 1 and the second locking hook 2 rotate, the initial state of the spring 10 is elongated, so that the end portions of the first push block 4 and the second push block 5 are in close contact with the bottom end surface of the hanging plate 3.

[0033] The end portions of the first locking hook 1 and the second locking hook 2 away from each other are provided with limiting grooves 8. The side surfaces of the first push block 4 and the second push block 5 close to the first locking hook 1 and the second locking hook 2 are fixedly installed with limiting blocks 9. The limiting blocks 9 are slidingly installed in the limiting grooves 8.​

[0034] When the first and second hooks 1 and 2 rotate, the limiting block 9 is clamped by the limiting block 2, so that the first push block 4 is displaced along the rotating direction of the first hook 1. If the spring 10 is pressed, the limiting block 2 can slide in the limiting groove 8.

[0035] The bottom end of the hanging plate 3 is provided with a groove 11 on the side facing the first hook 1, and the first push block 4 can be inserted into the groove 11. The side surface of the groove 11 is connected with a groove 12, and the first push block 4 can be inserted into the groove 12. The bottom end of the hanging plate 3 is provided with a groove 13 on the side facing the second hook 2, and the second push block 5 can be inserted into the third groove. The groove 12 and the groove 13 are communicated through the horizontal groove 3.11.

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

[0037] When the object is in a suspended state, the hanging plate 3 rotates to a vertical state. At this time, the first push block 4 is separated 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 12 under the action of the spring 10, so as to realize the overall locking of the device.

[0038] The top end of the sliding groove 3.1 is provided with a through groove 3.2, and the length of the through groove 3.2 is greater than the width of the vertical groove. The sliding block 6.3 is slidingly installed in the through groove 3.2. The spring 14 is arranged between the through groove 3.2 and the sliding block 6.3. The two ends of the spring 14 are fixedly connected with the sliding block 6.3 and the side wall of the through groove 3.2, respectively. When the locking rod 6.1 displaces the maximum distance, the end of the locking rod 6.1 is tangent to the bottom end surface of the hanging plate 3.

[0039] In the initial state of the spring two 14, the locking rod 6.1 passes through the third groove towards one end of the second push block 5, and is tangent to the bottom end surface of the hanging plate 3, the locking rod 6.1 enters the horizontal groove 3.11 towards one end of the first push block 4, when the second push block 5 is inserted into the groove three 13, the locking rod 6.1 is pushed towards the groove two 12, so that the locking rod 6.1 passes through the groove two 12 towards 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 into the groove two 12 again, so that the locking rod 6.1 is inserted into the limiting hole 5.1 towards one end of the second push block 5, and the locking rod 6.1 towards one end of the first push block 4 is blocked by the end of the first push block 4 and cannot pass through the groove two 12, achieving the effect of mutual locking between the first hook 1, the second hook 2 and the hanging plate 3.

[0040] The inclined surface one 11.1 is arranged between the groove one 11 and the groove two 12, and the inclined surface two 13.1 is arranged on both sides of the groove three 13.

[0041] In the process that the hanging plate 3 is switched from the initial state to the vertical state, the first push block 4 is subjected to the extrusion force of the inclined surface one 11.1, so that the spring one 10 is compressed and can be separated from the groove one 11, and when corresponding to the groove two 12, the spring is reset to insert the first push block 4 into the groove two 12, the second push block 5 is subjected to the extrusion force of the inclined surface two 13.1, so that the spring one 10 is compressed and can be separated from both sides of the groove three 13, preventing the second push block 5 from being locked when entering the groove three 13, so that the first hook 1 and the second hook 2 cannot be normally used.

[0042] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the scope of the utility model.
