[0001] This utility model relates to the field of puller technology, specifically an adjustable anti-disengagement puller. Background Technology

[0002] Pullers are commonly used tools in mechanical maintenance, mainly used to remove bearings, gears and other parts from shafts axially. They can be used as internal or external pullers. Currently, the working distance of existing pullers cannot be adjusted over a wide range, which limits their use to a certain number of workpieces (bearings, gears), resulting in low applicability. Furthermore, existing pullers are prone to detachment after contacting the workpiece, which seriously affects the working efficiency of the puller.

[0003] To address this, an adjustable anti-disengagement puller is proposed. Utility Model Content

With the cooperation of a sliding groove and a slider, the second threaded rod moves a movable block within a movable slot, thus adjusting the distance between the two connecting parts. A pull plate pulls a locking rod, which moves within a movable hole, stretching a spring. Once one end of the locking rod disengages from one of the locking holes, the hook can be positioned within the pipe, adjusting the overall length of the connecting part. After length adjustment, releasing the pull plate causes the spring to move the locking rod within the movable hole. Once one end of the locking rod engages with a corresponding locking hole, the connecting part is fixed. Compared to existing designs, this invention allows adjustment of both the distance between the two connecting parts and the overall length of the connecting part, making it suitable for a large number of workpieces (bearings, gears), thus offering high applicability. Furthermore, the second threaded rod ensures close contact between the connecting part and the outer wall of the workpiece, preventing disengagement and improving overall work efficiency.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example 1:

[0032] Please see Figure 1 , 24-6, This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: An adjustable anti-disengagement puller, comprising: a horizontal bar 1; a first threaded hole 2 is provided at the top of the horizontal bar 1, a first threaded rod 3 is internally threaded through the first threaded hole 2, and a drive head 4 is fixed at the top of the first threaded rod 3; two movable grooves 5 are provided at the top of the horizontal bar 1, movable blocks 6 are movably connected in each of the two movable grooves 5, and connecting parts are connected to the bottom of each of the two movable blocks 6; a sliding groove 10 is provided on the inner wall of each of the two movable grooves 5, a slider 11 is installed in the sliding groove 10, the movable block 6 is fixed at one end of the slider 11, and a second threaded hole 7 is provided at both ends of the horizontal bar 1; the second threaded hole 7 is internally threaded through the first threaded hole 2. The second threaded rod 8 is connected to the internal thread of the hole 7. One end of the second threaded rod 8 is fixed to the rotating shaft 9, and the other end of the second threaded rod 8 is rotatably connected to the movable block 6. The connecting part is composed of the pipe 12 and the hook bar 13. The pipe 12 is fixed to the bottom of the movable block 6, and the hook bar 13 is movably connected to the inside of the pipe 12. The outer wall of the pipe 12 has a movable hole 14, and the outer wall of the hook bar 13 has multiple locking holes 15. A locking rod 16 is movably installed in the movable hole 14. One end of the locking rod 16 is fixed to the pull plate 17, and the other end of the locking rod 16 is locked in one of the locking holes 15. A spring 18 is installed on the outer wall of the locking rod 16. One end of the spring 18 is fixed to the pull plate 17, and the other end of the spring 18 is fixed to the pipe 12.

[0033] Specifically, this utility model involves rotating the rotating shaft 9, which drives the second threaded rod 8 to move within the second threaded hole 7. With the cooperation of the sliding groove 10 and the slider 11, the second threaded rod 8 drives the movable block 6 to move within the movable groove 5, thereby adjusting the distance between the two connecting parts. Furthermore, by pulling the pull plate 17, the locking rod 16 is pulled, causing it to move within the movable hole 14. The spring 18 then stretches. Once one end of the locking rod 16 disengages from one of the locking holes 15, the position of the movable hook 13 within the pipe 12 can be adjusted, thus achieving overall length adjustment of the connecting parts. After the length of the connector is adjusted, the pull plate 17 is released. Under the action of the spring 18, the locking rod 16 will move within the movable hole 14. Once one end of the locking rod 16 is engaged with the corresponding locking hole 15, the connector can be fixed. Compared with the existing ones, this utility model can adjust the distance between the two connectors and the overall length of the connector, so that it can meet the needs of a large number of workpieces (bearings, gears), and has high applicability. In addition, the second threaded rod 8 will drive the connector to make close contact with the outer wall of the workpiece, avoiding the connector from disengaging and improving the overall work efficiency.

[0034] Example 2:

[0035] Please see Figure 1-3This utility model provides a technical solution: an adjustable anti-disengagement puller, wherein a countersunk hole 19 is provided at the top of a horizontal bar 1, and a ring 20 is fixed at the top of the horizontal bar 1 and outside the countersunk hole 19. A cavity 21 is provided inside the ring 20, and a groove 22 communicating with the cavity 21 is provided on the inner side of the ring 20. A long bar 23 is fixed at the top of the horizontal bar 1. A movable cavity 24 is provided at one end of the long bar 23, and a connecting pipe 27 communicating with the cavity 21 is installed at the other end of the long bar 23. A piston plate 25 is movably arranged in the movable cavity 24, and a push column 26 is fixed at one end of the piston plate 25. A first slot 30 is provided on the outer wall of the push column 26, and a second slot 31 is provided at the top of a movable block 6. A locking strip 32 is engaged in the first slot 30 and the second slot 31. An oil injection hole 28 is provided at the top of the long bar 23, and a sealing plug 29 is installed in the oil injection hole 28.

[0036] Specifically, before the overall operation, the operator can open the sealing plug 29 and pour lubricating oil into the movable cavity 24 of the elongated strip 23 through the oil injection hole 28. Then, the sealing plug 29 is used to seal the oil injection hole 28. The operator then rotates the rotating shaft 9, which drives the second threaded rod 8 to move within the second threaded hole 7. When the second threaded rod 8 moves, it uses the movable block 6 to push the push column 26 and the piston plate 25 to move within the movable cavity 24. When the piston plate 25 moves, it squeezes the lubricating oil in the cavity 21. The lubricating oil enters the cavity 21 of the ring 20 through the connecting pipe 27, and then enters the countersunk hole 19 through the trough 22. This achieves the purpose of lubricating the connection between the first threaded rod 3 and the first threaded hole 2. On the one hand, it improves the working efficiency of the first threaded hole 2 and the first threaded rod 3, and on the other hand, it reduces the wear of the first threaded hole 2 and the first threaded rod 3, thus extending their service life.

[0037] Working principle:

[0038] Before starting work, the operator can open the sealing plug 29 and pour lubricating oil into the movable cavity 24 of the elongated strip 23 through the oil filling hole 28. Then, the sealing plug 29 is used to seal the oil filling hole 28. The operator then rotates the rotating shaft 9, which drives the second threaded rod 8 to move within the second threaded hole 7. As the second threaded rod 8 moves, it uses the movable block 6 to push the push column 26 and piston plate 25 within the movable cavity 24. When the piston plate 25 moves, it squeezes the lubricating oil in the cavity 21, and the lubricating oil enters the ring 20 through the connecting pipe 27. Inside cavity 21, the lubricant enters countersunk hole 19 through groove 22 to lubricate the connection between the first threaded rod 3 and the first threaded hole 2. Then, the worker removes the retaining strip 32 from the first retaining groove 30 and the second retaining groove 31 to prevent the pushing column 26 from obstructing the operation of the movable block 6. Next, the worker adjusts the distance between the two connecting parts and the length of the connecting parts according to the workpiece dimensions. The worker first adjusts the length of the connecting parts by pulling the retaining rod 16 using the pull plate 17. At this time, the retaining rod 16 will be in the movable block... The moving part 16 moves within the movable hole 14, causing the spring 18 to stretch. Once one end of the locking rod 16 disengages from one of the locking holes 15, the hook 13 can be moved within the pipe 12, allowing adjustment of the overall length of the connector. After the connector length is adjusted, the pull plate 17 is released, and the spring 18 drives the locking rod 16 to move within the movable hole 14. Once one end of the locking rod 16 engages with a corresponding locking hole 15, the connector is fixed. Then, the distance between the two connectors is adjusted. Specifically, the working... By rotating the shaft 9, the operator moves the second threaded rod 8 within the second threaded hole 7. With the cooperation of the slide groove 10 and the slider 11, the second threaded rod 8 moves the movable block 6 within the movable groove 5, thereby adjusting the distance between the two connecting parts. At this time, the connecting parts are in close contact with the outer wall of the workpiece, and the first threaded rod 3 is located at the top of the workpiece shaft. The operator then uses an external driving device to drive the drive head 4, which drives the first threaded rod 3 within the first threaded hole 2. Finally, the workpiece can be disassembled by cooperating with the connecting parts.
