Description

Technical Field

[0001] The utility model relates to the technical field of lifting lug structures, in particular to a movable lifting lug. Background Art

[0002] A lifting lug is a lifting tool commonly used in the industrial field. It can lift objects through lifting devices such as wire ropes or chains and place them in the required position. Depending on the different working environments and the weight of the lifting objects, lifting lugs can be divided into different types, such as single lifting lugs, double lifting lugs, circular lifting lugs, square lifting lugs, etc.

[0003] In order to make some lifting ears more convenient to use during work, they are set to a rotatable style. When a breeze blows in the air during the use of such lifting ears, the lifting ears and the objects they carry may be blown to rotate together. These lifting ears are more dangerous during the rotation process, which makes these devices more inconvenient to use. In order to solve this technical problem, the utility model proposes a movable lifting ear. Utility Model Content

[0004] The main purpose of the utility model is to provide a movable lifting eye, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A movable lifting ear comprises a support rod, the outer surface of the support rod is connected to a bracket, a slide groove is provided inside the support rod, a ball bearing is installed inside the slide groove, the bracket is rotatably connected to a slide cylinder, the outer surface of the bracket is connected to a cross plate, a transmission mechanism is provided inside the cross plate, the bottom surface of the cross plate is connected to a support plate, the bottom surface of the bracket is connected to a limiting column, the outer surface of the limiting column is rotatably connected to a base, the inside of the base is connected to teeth, the outer surface of the teeth is meshed with a tooth plate, and the bottom surface of the base is installed with a lifting ear body.

[0007] Preferably, the transmission mechanism includes a threaded rod, the outer surface of the threaded rod is rotatably connected to the inside of the transverse plate, and the outer surface of the threaded rod is threadedly connected to the transmission plate.

[0008] Preferably, the outer surface of the transmission plate is slidably connected to the inside of the transverse plate, and the bottom surface of the transmission plate is connected to the upper surface of the tooth plate.

[0009] Preferably, the outer surface of the threaded rod is connected to a bevel gear 1, and the outer surface of the bevel gear 1 is meshed with a transmission rod.

[0010] Preferably, the outer surface of the transmission rod is rotatably connected to the inside of the cross plate, the outer surface of the transmission rod is rotatably connected to the inside of the bracket, and the end of the transmission rod away from the bevel gear one is engaged with the bevel gear two.

[0011] Preferably, the outer surface of the ball contacts the interior of the slide, the bottom surface of the support plate is slidably connected to the upper surface of the base, and the outer surface of the tooth plate is slidably connected to the interior of the base.

[0012] Preferably, the upper surface of the base is slidably connected to the bottom surface of the bracket, and the bottom surface of the horizontal plate is slidably connected to the upper surface of the base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, through the cooperation between the ball bearing and the tooth plate and other components, the ball bearing can first reduce the friction generated when the slide barrel rotates. When the rope passes through the slide barrel, the movement of the rope will cause the ball bearing to rotate with the slide barrel. The rotation of the slide barrel reduces the friction generated when the rope passes through the slide barrel, thereby increasing the service life of the rope and the slide barrel. The tooth plate can move up and down, and when the tooth plate moves downward, it will engage with the teeth. The engagement with the teeth prevents the base from rotating, thereby preventing the base from rotating with the lifting ear under the blowing of the wind. When the tooth plate moves upward, it can be separated from the teeth, allowing the base to rotate, thereby facilitating the user to adjust the position of the lifting ear body. It is very easy to use and solves the problem of the inconvenience of rotating the lifting ear in the air.

[0015] In the present invention, through the cooperation between the transmission mechanism and the limit column and other components, the transmission mechanism can control the position of the tooth plate, so that the position of the tooth plate moving up and down can be controlled, thereby avoiding deviation in the position of the tooth plate movement. The limit column will connect the base and the bracket, so that the bracket can move with the base when moving. At the same time, the limit column will not affect the rotation of the base, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a movable lifting ear includes a support rod 1, the outer surface of the support rod 1 is connected to a bracket 2, and a slide groove 3 is opened inside the support rod 1. The support rod 1 will fix the position of the bracket 2 so that the bracket 2 cannot move. The inner wall of the slide groove 3 is relatively smooth, and other objects will be subject to less friction when moving on the inner wall of the slide groove 3.

[0024] The ball 4 is installed inside the slide groove 3, and the slide cylinder 5 is connected to the inside of the bracket 2 for rotation. The slide groove 3 will limit the position of the ball 4 so that the movable position of the ball 4 will not deviate. The bracket 2 will limit the movable position of the slide cylinder 5 so that the slide cylinder 5 cannot move laterally, and also reduces the vibration generated when the slide cylinder 5 rotates.

[0025] The outer surface of the bracket 2 is connected to a transverse plate 6, a transmission mechanism 7 is provided inside the transverse plate 6, and the bottom surface of the transverse plate 6 is connected to a support plate 8. The bracket 2 will fix the position of the transverse plate 6, and the transverse plate 6 will not move at will through the bracket 2. The transverse plate 6 will fix the position of the support plate 8, and the support plate 8 will provide support for the transverse plate 6, so that the transverse plate 6 will not tilt.

[0026] The bottom surface of the bracket 2 is connected to the limiting column 9, and the outer surface of the limiting column 9 is rotatably connected to the base 10. The bracket 2 will fix the position of the limiting column 9, and when the bracket 2 moves, it will move with the limiting column 9, making the limiting column 9 unable to move. The limiting column 9 provides support for the base 10, so that when the bracket 2 moves, it can move with the base 10 through the limiting column 9.

[0027] The base 10 is internally connected to a tooth 11, and the outer surface of the tooth 11 is engaged with a tooth plate 12. The bottom surface of the base 10 is installed with a lifting ear body 13. The base 10 will fix the position of the tooth 11, and the tooth plate 12 will not rotate through the engagement of the tooth 11 and the tooth plate 12. The base 10 will fix the position of the lifting ear body 13, and when the base 10 moves, the lifting ear body 13 will move with it.

[0028] The transmission mechanism 7 includes a threaded rod 701, the outer surface of the threaded rod 701 is rotatably connected to the inside of the horizontal plate 6, and the outer surface of the threaded rod 701 is threadedly connected to the transmission plate 702. The horizontal plate 6 can limit the position of the threaded rod 701, thereby reducing the vibration generated when the threaded rod 701 rotates. A handle is provided above the threaded rod 701, which facilitates the user to rotate the threaded rod 701. When the threaded rod 701 rotates, it will move with the transmission plate 702, and the transmission plate 702 can limit the other end of the threaded rod 701.

[0029] The outer surface of the transmission plate 702 is slidably connected to the inside of the cross plate 6, and the bottom surface of the transmission plate 702 is connected to the upper surface of the tooth plate 12. The cross plate 6 will limit the position of the transmission plate 702 so that the transmission plate 702 will not rotate with the rotation of the threaded rod 701.

[0030] The outer surface of the threaded rod 701 is connected to the bevel gear 1 703, and the outer surface of the bevel gear 1 703 is engaged with the transmission rod 704. The threaded rod 701 fixes the position of the bevel gear 1 703. When the threaded rod 701 rotates, it will rotate with the bevel gear 1 703, and when the bevel gear 1 703 rotates, it will rotate with the transmission rod 704.

[0031] The outer surface of the transmission rod 704 is connected to the internal rotation of the cross plate 6, and the outer surface of the transmission rod 704 is connected to the internal rotation of the bracket 2. The end of the transmission rod 704 away from the bevel gear 1 703 is engaged with the bevel gear 2 705. The cross plate 6 will limit the position of the transmission rod 704, thereby reducing the vibration generated when the transmission rod 704 rotates. The bracket 2 can also reduce the vibration generated when the transmission rod 704 rotates. When the transmission rod 704 rotates, it will rotate with the bevel gear 2 705, and the rotation of the bevel gear 2 705 will move the threaded rod 701 and the transmission plate 702 on the other side.

[0032] The outer surface of the ball 4 contacts the inside of the slide 5, the bottom surface of the support plate 8 is slidably connected to the upper surface of the base 10, and the outer surface of the tooth plate 12 is slidably connected to the inside of the base 10. The contact between the slide 5 and the ball 4 reduces the friction generated when the slide 5 rotates. The support plate 8 contacts the base 10 to provide support for the cross plate 6. The base 10 limits the position to which the tooth plate 12 can move, thereby avoiding deviation in the position of the tooth plate 12.

[0033] The upper surface of the base 10 is slidably connected to the bottom surface of the bracket 2, and the bottom surface of the transverse plate 6 is slidably connected to the upper surface of the base 10. The contact between the base 10, the bracket 2 and the transverse plate 6 reduces the vibration generated when the base 10 rotates.

[0034] Working principle: When using this device, you first need to pass the rope through the slide 5. As the rope moves, the slide 5 will move with the ball 4. Then you need to rotate the threaded rod 701. The rotation of the threaded rod 701 will move the transmission plate 702 upward. At the same time, the rotation of the threaded rod 701 will rotate the bevel gear 1 703. The rotation of the bevel gear 1 703 will rotate the transmission rod 704. The rotation of the transmission rod 704 will rotate the bevel gear 2 705, allowing the tooth plates 12 on both sides to rise together to a position separated from the teeth 11. Then you can install the lifting ear body 13 on the item that needs to be lifted. After installation, you can rotate the threaded rod 701 to re-engage the tooth plate 12 with the teeth 11.
