Description

Technical Field

[0001] This utility model relates to the field of side-pull rotating lifting ring technology, specifically a side-pull rotating lifting ring anti-loosening device. Background Technology

[0002] A side-pull rotating ring is a mechanical component used in lifting and hoisting operations. It is mainly used to connect lifting equipment (such as hooks and wire ropes) to the object being lifted. Its core features are that it can withstand lateral tension and has a rotation function, allowing it to adapt to force requirements in different directions during hoisting and reducing stress concentration problems caused by rigid connections. A side-pull rotating ring anti-loosening device is a mechanical structure or component in the side-pull rotating ring structure that prevents the ring from loosening or falling off under force (especially lateral force, rotational force, or vibration) by limiting the relative rotation angle of key components, enhancing connection tightness, or providing additional locking force. Its core function is to ensure that the ring maintains a stable connection during lifting and hoisting operations, avoiding safety accidents caused by loosening.

[0003] However, existing side-pull swivel lifting rings lack anti-loosening functions. During use, equipment start-up and shutdown, object swaying, or environmental vibrations during lifting can exacerbate the dynamic load fatigue of the bolts, gradually destroying the preload and causing loosening. Furthermore, the unrestrained rotation of the handle can prevent the lifting ring from maintaining a stable angle during side pulling, causing the wire rope or lifting sling to deviate in the direction of force, resulting in localized stress concentration and ultimately, the lifting ring body breaking. These two points reflect the dangers of the lack of anti-loosening devices in existing side-pull swivel lifting rings, indicating that their safety needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a side-pull rotating lifting ring anti-loosening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A side-pull rotating lifting ring anti-loosening device includes a handle, a rotating shaft inserted into the bottom of the handle, a sleeve fixedly connected to the end of the rotating shaft, a spring fixedly connected to the outer surface of the rotating shaft, a retaining plate fixedly connected to the end of the spring away from the rotating shaft, a retaining sleeve fixedly connected to the retaining plate near the outer surface of the spring, a rotating shaft slidably connected to the outer surface of the retaining sleeve, and a plurality of slots are provided on the handle near the rotating shaft, with retaining plates inserted into the slots.

[0006] Preferably, a bolt is inserted inside the sleeve, a fixing block is fixedly connected to the top of the sleeve, an insert is inserted inside the fixing block, a locking block is fixedly connected to the end of the insert, a second spring is fixedly connected to the side of the locking block near the insert, a toothed belt abuts against the side of the locking block away from the insert, and a bolt is fixedly connected to the inner wall of the toothed belt.

[0007] Preferably, a washer is fixedly connected to the top of the sleeve near the center of the bolt, and a washer is fixedly connected to the outer surface of the sleeve near the rotating shaft.

[0008] Preferably, a nut is abutted against the bottom of the sleeve, and a bolt is inserted into the nut.

[0009] Preferably, the card block has a toothed groove on the side near the toothed belt, and the toothed belt is slidably connected to the inner wall of the toothed groove.

[0010] Preferably, the rotating shaft has a toothed ring groove on the inner wall near the chuck, and the inner wall of the toothed ring groove is slidably connected with annular teeth.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This side-pull rotating lifting ring anti-loosening device, through the arrangement of a locking plate, a handle, and ring teeth, allows for the following operation: Before the bolt is inserted into the sleeve, pulling the insert bar compresses the second spring, causing the insert bar to retract into the fixing block. After the bolt is inserted into the sleeve, stopping the pulling of the insert bar causes the second spring to press the locking block against the toothed band, preventing the bolt and sleeve from rotating relative to each other. Pulling the locking plate stretches the first spring, causing the locking plate to disengage from the bottom of the handle, which in turn causes the ring teeth to disengage from the toothed groove. At this time, rotating the handle allows for adjustment of the handle angle to meet usage requirements. Releasing the handle causes the first spring to engage the locking plate, and the ring teeth engage the toothed groove. Through the double locking of the bolt and sleeve, as well as the handle and sleeve, the lifting ring components are prevented from loosening, improving safety during use.

[0012] 2. This side-pull rotating lifting ring anti-loosening device, through the setting of washer one and washer two, during use, washer one increases the friction between the bolt and the sleeve, and washer two increases the friction between the sleeve and the handle, making it more difficult for the bolt and the sleeve, as well as the sleeve and the handle, to rotate relative to each other without human intervention, thereby helping to prevent the lifting ring component from loosening.

[0015] 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.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: A side-pull rotating ring anti-loosening device includes a handle 1, a rotating shaft 2 inserted into the bottom of the handle 1, a sleeve 3 fixedly connected to the end of the rotating shaft 2, a spring 4 fixedly connected to the outer surface of the rotating shaft 2, a retaining plate 5 fixedly connected to the end of the spring 4 away from the rotating shaft 2, a retaining sleeve 6 fixedly connected to the retaining plate 5 near the outer surface of the spring 4, and the rotating shaft 2 slidably connected to the outer surface of the retaining sleeve 6. Several slots 7 are provided on the handle 1 near the rotating shaft 2, and retaining plates 5 are inserted into the slots 7. In use, before the bolt 8 is inserted into the sleeve 3, pulling the insert 10 compresses the spring 12, causing the insert 10 to retract the retaining block 11 into the fixing block 9. After the bolt 8 is inserted into the sleeve 3, pulling the insert 10 stops, and under the action of the spring 12, the retaining block 11 presses against the toothed belt 13, preventing loosening. Bolt 8 and sleeve 3 rotate relative to each other, pulling the locking plate 5. Spring 4 is stretched, and locking plate 5 disengages from the bottom of handle 1, causing the ring tooth 19 to disengage from the toothed groove 18. At this time, rotating handle 1 can adjust the angle of handle 1 to meet usage requirements. When handle 1 is released, under the action of spring 4, locking plate 5 engages with handle 1, and ring tooth 19 engages with toothed groove 18. Through the double locking of bolt 8 and sleeve 3, as well as handle 1 and sleeve 3, the lifting ring components are prevented from loosening, improving usage safety. The rotating shaft 2 has a cylindrical groove at the locking tube 6, in which the locking tube 6 slides. Without human intervention, the locking tube 6 is locked inside the rotating shaft 2, preventing the handle 1 and rotating shaft 2 from rotating relative to each other. At the same time, the locking strip on the locking plate 5 is inserted into the slot at the bottom of the handle 1, which also prevents relative rotation.

[0017] In this embodiment, preferably, a bolt 8 is inserted inside the sleeve 3, a fixing block 9 is fixedly connected to the top of the sleeve 3, an insert 10 is inserted inside the fixing block 9, a locking block 11 is fixedly connected to the end of the insert 10, a second spring 12 is fixedly connected to the side of the locking block 11 near the insert 10, and a toothed belt 13 abuts against the side of the locking block 11 away from the insert 10. A bolt 8 is fixedly connected to the inner wall of the toothed belt 13. In use, before the bolt 8 is inserted into the sleeve 3, the insert 10 is pulled, the second spring 12 is compressed, and the insert 10 drives the locking block 11 to retract into the fixing block 9. After the bolt 8 is inserted into the sleeve 3, the pulling of the insert 10 is stopped, and under the action of the second spring 12, the locking block 11 abuts against the toothed belt 13 to prevent the bolt 8 from rotating relative to the sleeve 3. The locking block 11 is provided with two grooves, which are matched with the toothed blocks on the toothed belt 13 to lock the bolt 8.

[0018] In this embodiment, preferably, a washer 14 is fixedly connected to the top of the sleeve 3 near the center of the bolt 8, and a washer 25 is fixedly connected to the outer surface of the sleeve 3 near the rotating shaft 2. In use, washer 14 increases the friction between the bolt 8 and the sleeve 3, and washer 25 increases the friction between the sleeve 3 and the handle 1. This makes it more difficult for the bolt 8 and the sleeve 3, as well as the sleeve 3 and the handle 1, to rotate relative to each other without human intervention, thereby helping to prevent the lifting ring component from loosening. Both washer 14 and washer 25 are made of silicone, which is non-slip and increases friction.

[0019] In this embodiment, preferably, the bottom of the sleeve 3 abuts against the nut 16, and the nut 16 is fitted with a bolt 8. In use, after inserting the bolt 8 into the sleeve 3 and the part to be fixed, the nut 16 can be fitted onto the bolt 8 and locked. This further enhances the connection.

[0020] In this embodiment, preferably, the locking block 11 has a toothed groove 17 on the side near the toothed belt 13, and the toothed belt 13 is slidably connected to the inner wall of the toothed groove 17. When in use, without human intervention, the toothed blocks on the toothed belt 13 are locked into the toothed groove 17 to lock the bolt 8 and the sleeve 3. The toothed belt 13 has multiple toothed blocks evenly arranged on it, which makes it convenient to lock the bolt 8 on any surface.

[0021] In this embodiment, preferably, the inner wall of the rotating shaft 2 near the retaining sleeve 6 is provided with a toothed ring groove 18, and the inner wall of the toothed ring groove 18 is slidably connected with an annular tooth 19. In use, without human intervention, the toothed blocks on the annular tooth are engaged in the toothed ring groove 18 to prevent the handle 1 from rotating relative to the sleeve 3. The toothed ring groove 18 is only opened in the part of the rotating shaft 2 near the annular tooth. When the retaining sleeve 6 moves outward, the annular tooth can be disengaged from the toothed ring groove 18, changing the angle of the handle 1.

[0022] Working principle: In this embodiment, before the bolt 8 is inserted into the sleeve 3, the insert 10 is pulled, the spring 12 is compressed, and the insert 10 drives the locking block 11 to retract into the fixing block 9. After the bolt 8 is inserted into the sleeve 3, the pull of the insert 10 is stopped. Under the action of the spring 12, the locking block 11 abuts against the toothed belt 13 to prevent the bolt 8 and the sleeve 3 from rotating relative to each other. The locking plate 5 is pulled, the spring 4 is stretched, and the locking plate 5 is disengaged from the bottom of the handle 1, which drives the ring tooth 19 to disengage from the toothed groove 18. At this time, rotating the handle 1 can adjust the angle of the handle 1 to meet the usage requirements. When the handle 1 is released, the locking plate 5 is locked into the handle 1 under the action of the spring 4, and the ring tooth 19 is locked into the toothed groove 18. Through the double locking of the bolt 8 and the sleeve 3, as well as the handle 1 and the sleeve 3, the lifting ring components are prevented from loosening, thus improving the safety of use.
