Description

Technical Field

[0001] This utility model relates to the field of eye bolt technology, specifically to a double eye bolt. Background Technology

[0002] Eye bolts are standardized connectors with a ring-shaped structure and a screw. Their main function is to connect tightly to the threaded hole of the object being lifted through the screw. By using the ring-shaped structure in conjunction with lifting equipment, they can lift, move, or fix various heavy objects, effectively transfer and distribute the load, and ensure the safety and stability of the lifting process.

[0003] Double eye bolts are integrated lifting connectors that combine a screw and two eye rings. Their core function is to achieve a secure fixation by connecting the screw to the object being lifted via a threaded connection, and then use the two eye rings to distribute the load with the lifting equipment. Double eye bolts have advantages over single eye bolts in terms of balanced lifting and load distribution.

[0004] However, considering that existing double eye bolts are usually designed as a single unit during production, with two eye bolts fixedly connected to a bolt by welding, and considering that the position and orientation of the eye bolts are not easy to adjust during actual use, it is difficult to adjust them according to the center of gravity of the object being lifted and the hook position and angle of the lifting equipment. This leads to a decrease in the effectiveness and lifting stability of the double eye bolts. Utility Model Content

[0005] The purpose of this invention is to provide a double eye bolt.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A double eye bolt is provided, including a stud, a connecting plate, two eye rings and four limiting mechanisms. The stud is fixedly installed on the bottom of the connecting plate. Both eye rings are slidably installed on the connecting plate through an adjustment mechanism. The adjustment mechanism is used to adjust the position of the two eye rings. The four limiting mechanisms are respectively hinged to the two eye rings. The limiting mechanisms are used to limit the movement of external lifting equipment.

[0008] The adjustment mechanism includes two movable blocks, and two sliding grooves are formed on the connecting plate. The two movable blocks are slidably installed in the two sliding grooves, and two lifting rings are rotatably installed on the two movable blocks via two cylindrical rods. Through the movable blocks and cylindrical rods, the lifting rings can be moved and rotated, thereby adjusting the position and direction of the lifting rings.

[0009] Furthermore, the adjustment mechanism also includes a bidirectional threaded rod and a steering mechanism. The bidirectional threaded rod is rotatably mounted on the connecting plate and is threadedly connected to both moving blocks. The steering mechanism is used to drive the cylindrical rod to rotate.

[0010] Furthermore, the steering mechanism includes two sleeves and two telescopic rods. The two sleeves are respectively snapped onto two cylindrical rods, and the two telescopic rods are respectively hinged onto the two sleeves via two hinge blocks. The movement of the telescopic rods can drive the sleeves to rotate, thereby driving the cylindrical rods and the lifting ring to rotate.

[0011] Furthermore, the steering mechanism also includes a movable plate, a groove is provided on the connecting plate, the movable plate is slidably installed in the groove, and the movable plate is fixedly connected to both telescopic rods.

[0012] Furthermore, the steering mechanism also includes a threaded rod, which is rotatably mounted on the connecting plate and threadedly connected to the moving plate.

[0013] Furthermore, each limiting mechanism includes a limiting plate with a through slot, and the limiting plate is hinged to the lifting ring via a hinged post. The two limiting plates on each lifting ring limit the effective movement position of the lifting ring, reducing the range of movement of the lifting equipment on the lifting ring and the swing amplitude of the lifting ring.

[0014] Furthermore, the limiting mechanism also includes a locking post, which is connected to the limiting plate by a spring, and the locking post is slidably connected to the inner wall of the limiting plate. A locking groove is provided on the lifting ring, and the locking post engages with the locking groove.

[0015] Furthermore, the limiting mechanism also includes a pull rod, which is fixedly installed on the snap-fit ​​post and passes through the limiting plate.

[0016] The beneficial effects of this utility model are as follows: This double eye bolt, through the setting of the adjustment mechanism and the steering mechanism, can adjust the axial direction of the lifting ring. At the same time, it can drive the lifting ring to move through the moving block and adjust the position of the lifting ring, thereby improving the use effect and lifting stability of the double eye bolt. In addition, through the setting of the limiting mechanism, the connection position between the lifting equipment and the lifting ring can be limited, reducing the swaying amplitude between the lifting equipment and the lifting ring during the lifting of the double eye bolt, thereby further improving the stability and safety of the double eye bolt during lifting.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent.

[0026] Reference Figure 1 and Figure 2 The double eye bolt shown includes a stud 1, a connecting plate 2, two eye rings 3, and four limiting mechanisms 5. The stud 1 is fixedly installed on the bottom of the connecting plate 2, and the two eye rings 3 and the stud 1 are connected through the connecting plate 2. The two eye rings 3 are slidably installed on the connecting plate 2 through the adjusting mechanism 4. The two eye rings 3 can evenly distribute the load. The adjusting mechanism 4 is used to adjust the position of the two eye rings 3 to adapt to different lifting conditions. The four limiting mechanisms 5 are respectively hinged to the two eye rings 3. The limiting mechanisms 5 are used to limit the external lifting equipment, thereby reducing the swing amplitude of the eye rings 3 during lifting and improving the stability during lifting.

[0027] Reference Figure 2 and Figure 3Specifically, the adjusting mechanism 4 includes two moving blocks 42, and the connecting plate 2 has two sliding grooves 43. The sliding grooves 43 guide the moving blocks 42. The two moving blocks 42 are slidably installed in the two sliding grooves 43 respectively. Through the sliding effect of the moving blocks 42, the cylindrical rod 44 can be moved, thereby moving the lifting ring 3 and adjusting the position of the lifting ring 3. The two lifting rings 3 are rotatably installed on the two moving blocks 42 through the two cylindrical rods 44 respectively. Through the rotation effect of the cylindrical rods 44, the lifting rings 3 can be rotated, thereby adjusting the direction of the lifting rings 3.

[0028] Reference Figure 2 and Figure 3 More specifically, the adjustment mechanism 4 also includes a bidirectional threaded rod 41 and a steering mechanism 45. The bidirectional threaded rod 41 is rotatably mounted on the connecting plate 2, and the bidirectional threaded rod 41 is threadedly connected to both moving blocks 42. Through the rotation effect of the bidirectional threaded rod 41, the two moving blocks 42 can be driven to move closer or further apart. The steering mechanism 45 is used to drive the cylindrical rod 44 to rotate. Through the steering mechanism 45, both cylindrical rods 44 can be driven to rotate simultaneously.

[0029] Reference Figure 3 and Figure 4 Specifically, the steering mechanism 45 includes two sleeves 451 and two telescopic rods 453. The two sleeves 451 are respectively snapped onto two cylindrical rods 44. The rotation of the sleeves 451 can drive the cylindrical rods 44 to rotate. The two telescopic rods 453 are respectively hinged onto the two sleeves 451 through two hinge blocks 452. The movement of the telescopic rods 453 can drive the hinge blocks 452 to move, thereby driving the sleeves 451 to rotate.

[0030] Reference Figure 2 and Figure 4 More specifically, the steering mechanism 45 also includes a movable plate 454. A groove 455 is provided on the connecting plate 2, which guides the movable plate 454. The movable plate 454 is slidably installed within the groove 455 and is fixedly connected to both telescopic rods 453. The movement of the movable plate 454 simultaneously moves both telescopic rods 453, thereby causing both sleeves 451 to rotate simultaneously. The steering mechanism 45 also includes a threaded rod 456, which is rotatably installed on the connecting plate 2 and threadedly connected to the movable plate 454. The rotation of the threaded rod 456 moves the movable plate 454.

[0031] Reference Figure 3 and Figure 5Each limiting mechanism 5 includes a limiting plate 51, on which a through groove 57 is provided. The limiting plate 51 is hinged to the lifting ring 3 via a hinge post 52. Each lifting ring 3 is provided with two limiting plates 51. The through groove 57 is used to avoid the lifting ring 3, so that the limiting plate 51 can rotate around the hinge post 52. Through the rotation effect of the limiting plate 51, the position of the limiting plate 51 on the lifting ring 3 can be adjusted to achieve the limiting function. The limiting mechanism 5 also includes a locking post 53, which is connected to the limiting plate 51 by a spring 54. The locking post 53 is slidably connected to the inner wall of the limiting plate 51. Through the elastic force of the spring 54, the locking post 53 remains locked with the locking groove 56 when no external force is applied. The lifting ring 3 has a locking groove 56, and the locking post 53 locks with the locking groove 56. Through the locking effect of the locking post 53 and the locking groove 56, the limiting plate 51 can be limited and kept fixed. The limiting mechanism 5 also includes a pull rod 55, which is fixedly installed on the locking post 53 and passes through the limiting plate 51. By pulling the pull rod 55, the locking post 53 can be moved, thereby releasing the locking effect between the locking post 53 and the locking groove 56.

[0032] Reference Figures 1 to 5 This double-eye bolt, through its adjustment and steering mechanisms, allows for axial adjustment of the lifting eye. Simultaneously, a moving block can move the lifting eye, adjusting its position and thus improving its performance and lifting stability. Furthermore, a limiting mechanism restricts the connection between the lifting equipment and the lifting eye, reducing the swaying amplitude during lifting and further enhancing stability and safety.
