Description

Technical Field

[0001] This utility model relates to the field of positioning technology for double-envelope worm gear boxes, and more specifically, it relates to a double-envelope worm gear box that is easy to position. Background Technology

[0002] In existing technologies, double-envelope worm gearboxes, as important speed reduction devices in mechanical transmission systems, are widely used in industrial fields such as metallurgical equipment, mining machinery, hoisting and transportation, and petrochemicals. They are primarily used for power transmission and speed regulation, converting high-speed rotary motion into low-speed, high-torque output through the meshing transmission of the worm and worm wheel. In practical applications, double-envelope worm gearboxes are typically mounted and fixed on equipment mounting bases, frames, or other mounting locations. Power transmission is achieved through connections to the power source and load. Daily maintenance and periodic inspections of the worm gearbox are also important. When performing operations such as adjusting the installation position, the worm gear box needs to be disassembled and reinstalled. However, in the existing technology, the installation and disassembly of the worm gear box and the mounting base usually require the use of professional tools such as wrenches, socket wrenches, and screwdrivers to tighten and loosen the connecting fasteners. The operation process is relatively cumbersome, which increases the time cost and labor intensity of equipment maintenance. At the same time, when there are situations such as incomplete tool equipment, tool models not matching fastener specifications, or damaged or lost tools on the production site, it is easy to make it impossible to disassemble and assemble the worm gear box in a timely and convenient manner, which affects the maintenance efficiency and flexibility of the equipment.

[0003] Secondly, although some double-envelope worm gearboxes on the market achieve tool-free installation and disassembly by setting up certain components, these existing tool-free positioning structures generally suffer from defects such as simple connection mechanism design, insufficient fixing firmness, and lack of overall stability. After the worm gearbox is installed and positioned, its fixing structure is easily affected by various external forces and equipment operating environment factors during the actual operation of the worm gearbox, such as torque load generated by the transmission system, impact load generated by equipment start-up and shutdown, and vibration factors in the working environment. This can lead to the original fixed structure of the worm gearbox being loosened or even the worm gearbox accidentally falling off and separating from the mounting base. This results in problems such as reduced transmission accuracy affecting equipment performance, worm gearbox falling off causing equipment damage, and loose fixing leading to increased noise, affecting the normal working performance and transmission effect of the double-envelope worm gearbox.

[0012] The present invention is further configured such that a straight groove is provided on the inner side of the locking sleeve, and the top end of the straight groove is connected to one end of the fastening groove.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a double-envelope worm gear box that is easy to position, and has the following beneficial effects: 1. By detachably installing a locking sleeve on the base plate, a locking rod detachably installed inside the locking sleeve, a rotating sleeve rotatably installed outside the locking sleeve, a fixed fastening block outside the locking rod, and a sliding push rod installed on the side wall of the locking sleeve, a guide groove with a variable diameter is opened inside the rotating sleeve, an adapter spring is installed outside the push rod, a fastening groove is opened inside the locking sleeve, and a vertical groove, a drainage groove, and a push groove are opened outside the locking rod. This achieves tool-free and convenient disassembly and assembly of the worm gear box assembly and the mounting base. During disassembly, rotating the rotating sleeve forward causes the guide groove to rotate, thus removing the limitation on the push rod. The forward rotation lock... The fixed sleeve allows the push rod to slide from the push groove into the diversion groove and move to the vertical groove, causing the locking block to enter the straight groove. Pulling the locking sleeve allows the locking block and push rod to slide off, thus removing the locking sleeve and locking rod. The operator only needs to rotate the rotating sleeve, rotate the locking sleeve, and pull the locking sleeve to complete the disassembly. There is no need to use professional tools such as wrenches, socket wrenches, and screwdrivers. This effectively avoids the problem of the worm gear box not being able to be disassembled and assembled in time due to incomplete tool equipment, incompatible models and fastener specifications, or damaged or lost tools, thus improving the maintenance efficiency and usage flexibility of the double-envelope worm gear box.

[0014] 2. By cooperating with the pressing sleeve, locking rod, connecting frame, and connecting groove to form a rotation limit for the rotating sleeve, the push rod is constrained by its insertion in the push groove, the fastening block limits the fastening of the fastening groove, the push rod and guide groove work together, and the pressing rod and pressing plate limit the rotation through the rotating hole and rotating groove, a multi-level stable locking mechanism is established. After installation, the pressing rod and pressing plate support the pressing sleeve to one side of the action plate. The pressing sleeve, locking rod, connecting frame, and connecting groove work together to restrict the rotation of the rotating sleeve. This multi-level locking mechanism effectively resists the influence of external forces such as torque load generated by the transmission system, impact load generated by equipment start-up and stop, and vibration factors in the working environment. It effectively prevents the worm gear box fixing structure from loosening or accidentally falling off and separating from the mounting base, avoiding problems such as decreased transmission accuracy affecting equipment performance, worm gear box falling off causing equipment damage, and loose fixing leading to increased noise. It ensures the working stability and transmission effect of the double-envelope worm gear box. Attached Figure Description

[0020] Please see Figures 1-5A double-envelope worm gear box for easy positioning includes a worm gear box assembly 1 and a mounting base 2. The bottom end of the worm gear box assembly 1 has a base plate 3, which is detachably mounted on the mounting base 2. A locking sleeve 4 is detachably mounted on the top of the base plate 3. A mating block 5 is fixedly mounted on the outer side of the locking sleeve 4. A locking rod 6 is detachably mounted on the inner side of the locking sleeve 4. A rotating sleeve 7 is rotatably mounted on the outer side of the locking sleeve 4. A fastening block 8 is fixedly mounted on the outer side of the locking rod 6. A pushing rod 9 slides on the side wall of the locking sleeve 4. Multiple connecting grooves 10 are opened on one side of the rotating sleeve 7. A guide groove 11 with a variable diameter is opened on the inner side of the rotating sleeve 7. Multiple connecting frames 12 are fixedly mounted on the outer side of the locking sleeve 4. A locking rod 13 is rotatably mounted on the inner side of the connecting frame 12, with one end of the locking rod 13 inserted into the connecting groove 10. An actuating plate 14 is rotatably mounted on the outer side of the locking sleeve 4, and a rotating hole 1 is opened on the actuating plate 14. 5 and rotating groove 16, rotating hole 15 is opened at one end of rotating groove 16, rotating groove 16 is arc-shaped and opened on action plate 14, a cooperating block 17 is fixedly provided on one side of action plate 14, cooperating block 17 and cooperating block 5 are connected by cooperating spring 18, locking sleeve 4 is provided with pressing sleeve 19 on the outside, pressing sleeve 19 is fixedly connected with pressing rod 20 on one side, pressing rod 20 is fixedly provided with pressing plate 21, two pressing plates 21 are fixedly set on pressing rod 20, pushing rod 9 is provided with adapter spring 22 on the outside, pushing rod 9 is connected to the outer wall of locking sleeve 4 through adapter spring 22, locking sleeve 4 is provided with fastening groove 23 on the inside, locking rod 6 is provided with vertical groove 24, diversion groove 25 and pushing groove 26 on the outside, pushing groove 26 is opened at one end of diversion groove 25, and one end of vertical groove 24 is connected to the other end of diversion groove 25.

[0021] In this embodiment, when the worm gear box assembly 1 needs to be removed, the actuating plate 14 is first rotated forward. The actuating plate 14 then drives the cooperating block 17 on one side to rotate forward. The cooperating block 17 then drives the cooperating rod 27 on one side to rotate forward along the cooperating hole 28. The cooperating block 17, in conjunction with the mating block 5, compresses the cooperating spring 18. Simultaneously, the actuating plate 14 drives the rotating hole 15 and the rotating groove 16 to rotate forward. When the cooperating spring 18 is compressed to its limit, the rotating hole 15 rotates to a position concentric with the pressing plate 21. Then, the pressing sleeve 19 is pushed, causing the pressing sleeve 19 to drive the inner sliding block 31 to slide along the sliding groove 30. The pressing sleeve 19 also drives the pressing rod 20 and the pressing plate 21 to gradually slide into the rotating hole 15. At the same time, the pressing sleeve 19... The action plate 14, in conjunction with the compression spring 29, compresses the spring 29. When the spring 29 is compressed to its limit, the compression plate 21, located in the middle section of the compression rod 20, slides through the rotating hole 15 and moves to the other side of the action plate 14. Then, the action plate 14 is released, causing the coordinating spring 18 to reset and push the coordinating block 17. The coordinating block 17 then drives one side of the coordinating rod 27 to rotate in reverse along the coordinating hole 28. At the same time, the coordinating block 17, through the action plate 14, drives the rotating hole 15 and the rotating groove 16 to rotate in the opposite direction, causing the compression rod 20 to enter the rotating groove 16. When the outer wall of the compression rod 20 contacts one end of the inner wall of the rotating groove 16, the action plate 14 stops rotating. At this time, the compression rod 20, in conjunction with the middle section of the compression plate 21, compresses the spring 29. 1. The pressing sleeve 19 is positioned to one side of the action plate 14, causing the pressing sleeve 19 to gradually stop limiting one end of the locking rod 13. Next, the rotating sleeve 7 is rotated forward, causing the multiple connecting slots 10 on one side to rotate. Then, the inner wall of the connecting slot 10 presses against one end of the locking rod 13. Due to the arc design of the inner wall of the connecting slot 10 and the end of the locking rod 13, as well as the rotational connection between the locking rod 13 and the connecting frame 12, the connecting slot 10 will squeeze out one end of the locking rod 13, causing the locking rod 13 to rotate in the connecting frame 12 and causing the other end of the locking rod 13 to rotate inward. At the same time, the rotating sleeve 7 causes the guide slot 11 with a variable diameter on the inner side to rotate forward, causing the wider side of the guide slot 11 to rotate to the position corresponding to the push rod 9. The inner wall of the guide groove 11 no longer limits the outer end of the push rod 9. Then, the locking sleeve 4 is rotated forward, causing the locking sleeve 4 to drive the push rod 9, which is slidably mounted on the side wall, to rotate forward. The arc-shaped structure at the connection between the push groove 26 and the diversion groove 25 compresses the arc-shaped structure at one end of the push rod 9, causing one end of the push rod 9 to slide out of the push groove 26 and enter the diversion groove 25 to perform forward sliding. The other end of the push rod 9 drives the adapter spring 22 to stretch outward. At the same time, the locking sleeve 4 drives the straight groove 32 and the fastening groove 23 opened on the inner side to rotate forward. When the locking sleeve 4 drives the push rod 9 to rotate to the other end of the diversion groove 25, one end of the push rod 9 moves to the position corresponding to one end of the vertical groove 24. The adapter spring 22 drives the push rod 9 to slide and reset, causing the push rod 9 to slide inward.This allows one end of the push rod 9 to insert into one end of the vertical groove 24, which is connected to the other end of the diversion groove 25. Simultaneously, the locking sleeve 4 rotates the straight groove 32 to the position corresponding to the fastening block 8. Then, the locking sleeve 4 is pulled to one side, causing the fastening block 8 to enter the straight groove 32. The locking sleeve 4 then causes the push rod 9 to slide along the vertical groove 24, allowing the push rod 9 to slip out of the vertical groove 24 and the fastening block 8 to slip out of the straight groove 32, thus removing the locking sleeve 4 at this point. Then, the locking rod 6 is pulled in the opposite direction to remove it. Following the same steps, the other corresponding locking rods 6 and locking sleeves 4 are removed in sequence. Finally, the worm gear box assembly 1, along with the base plate 3, can be removed from above the mounting base 2.

[0022] Please see Figures 2-5 As a further implementation of the overall equipment: one end of the pressing sleeve 19 adopts an angled structure design.

[0023] The inner wall of the connecting groove 10 and both ends of the locking rod 13 are designed with arc corners. A coordinating rod 27 is connected to one side of the coordinating block 17, and a coordinating hole 28 is opened in the mating block 5. The coordinating spring 18 is movably sleeved on the outside of the coordinating rod 27, and one end of the coordinating rod 27 slides into the coordinating hole 28.

[0024] The vertical groove 24 and the propulsion groove 26 have the same depth, and the depth of the vertical groove 24 and the propulsion groove 26 is slightly deeper than that of the diversion groove 25. The connection between the vertical groove 24 and the diversion groove 25, the connection between the propulsion groove 26 and the diversion groove 25, and the end of the propulsion rod 9 all adopt an arc-angle structure design.

[0025] A pressing spring 29 is connected to one side of the pressing sleeve 19, and the other end of the pressing spring 29 is connected to the action plate 14 in contact. The pressing spring 29 is movably sleeved on the outside of the pressing rod 20.

[0026] A sliding groove 30 is provided on the outer side of the locking sleeve 4, and a sliding block 31 is slidably provided in the sliding groove 30. The sliding block 31 is fixedly provided on the inner side of the pressing sleeve 19.

[0027] A straight groove 32 is provided on the inner side of the locking sleeve 4, and the top of the straight groove 32 is connected to one end of the fastening groove 23.

[0028] More specifically, when installing the worm gear box assembly 1, first place the worm gear box assembly 1 on the corresponding position on the mounting base 2, ensuring that the pre-drilled mounting holes on the base plate 3 and the mounting base 2 are concentrically aligned. Then, pass the locking rod 6 through the pre-drilled mounting hole from one side of the mounting base 2, and then re-fit the locking sleeve 4 from the other side of the base plate 3 onto the outside of the locking rod 6, allowing the fastening block 8 to slide into the straight groove 32. One end of the push rod 9, located on the side wall of the locking sleeve 4, slides into the vertical groove 24. When the locking sleeve 4 is fully fitted onto the outside of the locking rod 6, the fastening block 8 moves to one end of the straight groove 32, and the push rod 9 moves to one end of the vertical groove 24. Reverse rotation of the locking sleeve 4 causes the push rod 9 to rotate in the opposite direction. The arc-shaped structure at the connection between the drainage groove 25 and the vertical groove 24 then engages with the push rod. The arc-shaped structure at one end of the push rod 9 applies pressure, causing one end of the push rod 9 to slide out of the vertical groove 24 and enter the drainage groove 25 to perform reverse sliding. Simultaneously, the push rod 9 drives the adapter spring 22 connected to the other end to stretch outwards again. At the same time, the locking block 8 enters the locking groove 23 and moves in the reverse direction. When the push rod 9 moves to the position corresponding to the push groove 26, the locking sleeve 4 stops rotating, and the locking block 8 is in its original position inside the locking groove 23. At this time, the adapter spring 22 resets and pulls the push rod 9, causing the push rod 9 to slide inwards and reset. One end of the push rod 9 is reinserted into the push groove 26. Then, the rotating sleeve 7 rotates in the reverse direction, causing the multiple connecting grooves 10 on one side to rotate in the reverse direction. Simultaneously, the rotating sleeve 7 drives the guide groove 11 with a variable diameter on the inner side to rotate in the reverse direction. When the guide groove 11 is fully rotated and reset, the narrower inner wall of the guide groove 11 limits the outer end of the push rod 9, preventing the push rod 9 from sliding outward. The push rod 9 and the push groove 26 cooperate to limit the locking rod 6, preventing the locking sleeve 4 and the locking rod 6 from rotating relative to each other. At this time, the rotating sleeve 7 just drives the connecting groove 10 to fully rotate and reset, causing the corresponding connecting groove 10 to rotate to the position corresponding to the original locking rod 13. Then, the action plate 14 is rotated forward again, causing the action plate 14 to drive the side cooperating block 17 to rotate forward again. Then, the cooperating block 17 drives the side cooperating rod 27 to rotate forward along the cooperating hole 28. The cooperating block 17 and the mating block 5 cooperate again to squeeze the cooperating spring 18. At the same time, the action plate 14 drives the rotating hole 15 and the rotating groove 16 to rotate again. When rotating clockwise, when the rotating hole 15 rotates again to a position concentric with the pressing plate 21, the pressing spring 29 pushes the pressing sleeve 19 to drive the inner sliding block 31 to slide and reset along the sliding groove 30. Simultaneously, the pressing sleeve 19 drives one side of the pressing rod 20 and both pressing plates 21 to slide and reset. Due to the angled design of one end of the pressing sleeve 19 and the arc-shaped design of the locking rod 13, one end of the pressing sleeve 19 gradually pushes the corresponding end of the locking rod 13 outwards. Then, the locking rod 13 rotates in the reverse direction within the connecting frame 12, causing the other end of the locking rod 13 to re-engage in the original connecting groove 10. At this point, the pressing spring 29 is fully reset, and the pressing plate 21 at the top of the pressing rod 20 moves back to its original position on the action plate 14.Then, the actuating plate 14 is released, causing the cooperating spring 18 to reset and push the cooperating block 17 to reverse reset. The cooperating block 17 will also cause one side of the cooperating rod 27 to reverse reset along the cooperating hole 28. Simultaneously, the cooperating block 17 will drive the rotating hole 15 and rotating groove 16 to rotate in the opposite direction via the actuating plate 14, causing the rotating hole 15 and rotating groove 16 to reverse reset to positions not corresponding to the pressing rod 20 and pressing plate 21. Then, the pressing rod 20, in conjunction with its top pressing plate 21, supports the pressing sleeve 19 to one side of the actuating plate 14. The upper sliding block 31 and the sliding groove 30 limit the movement of the pressing sleeve 19, preventing it from moving. Then, the pressing sleeve 19, together with the locking rod 13, the connecting frame 12, and the connecting groove 10, forms a rotation limit on the rotating sleeve 7, preventing accidental rotation and ensuring a secure engagement between the locking sleeve 4 and the locking rod 6. Following the same steps, other locking sleeves 4 and locking rods 6 are then fixed in place, achieving tool-free, convenient disassembly and positioning of the double-envelope worm gear box and ensuring its stability after installation.

[0029] In summary, during the use or operation of the overall equipment: when it is necessary to remove the worm gear box assembly 1, first rotate the actuating plate 14 in the forward direction. Then, the actuating plate 14 will drive the cooperating block 17 on one side to rotate in the forward direction. Then, the cooperating block 17 will drive the cooperating rod 27 on one side to rotate in the forward direction along the cooperating hole 28. The cooperating block 17 will cooperate with the mating block 5 to compress the cooperating spring 18. At the same time, the actuating plate 14 will drive the rotating hole 15 and the rotating groove 16 to rotate in the forward direction. When the cooperating spring 18 is compressed to its limit, the rotating hole 15 will just rotate to a position concentric with the pressing plate 21. Then, the pressing sleeve 19 will be pushed, so that the pressing sleeve 19 will drive the inner sliding block 31 to slide along the sliding groove 30. The pressing sleeve 19 will also drive the pressing rod 20 on one side and the pressing plate 21 to gradually slide into the rotating hole 15. When the pressing sleeve 19 cooperates with the actuating plate 14 to compress the pressing spring 29, the pressing spring 29 is compressed to its limit. When the pressing spring 29 is compressed to its limit, the pressing plate 21, located in the middle section of the pressing rod 20, slides through the rotating hole 15 and moves to the other side of the actuating plate 14. Then, the actuating plate 14 is released, causing the cooperating spring 18 to reset and push the cooperating block 17. The cooperating block 17 then drives one side of the cooperating rod 27 to rotate in reverse, and the cooperating block 17 will also drive one side of the cooperating rod 27 to rotate in reverse along the cooperating hole 28. At the same time, the cooperating block 17 will drive the rotating hole 15 and the rotating groove 16 to rotate in the opposite direction through the actuating plate 14, so that the pressing rod 20 enters the rotating groove 16. When the outer wall of the pressing rod 20 contacts one end of the inner wall of the rotating groove 16, the actuating plate 14 stops rotating. At this time, the pressing rod 20 cooperates with the middle section of the pressing spring 20 to rotate in reverse. The pressing plate 21 limits the pressing sleeve 19 to one side of the actuating plate 14, causing the pressing sleeve 19 to gradually no longer limit one end of the locking rod 13. Next, the rotating sleeve 7 rotates forward, causing multiple connecting slots 10 on one side to rotate. The inner wall of the connecting slots 10 then presses against one end of the locking rod 13. Due to the arc design of the inner wall of the connecting slots 10 and the end of the locking rod 13, as well as the rotating connection between the locking rod 13 and the connecting frame 12, the connecting slots 10 expel one end of the locking rod 13, causing the locking rod 13 to rotate within the connecting frame 12 and causing the other end of the locking rod 13 to rotate inward. Simultaneously, the rotating sleeve 7 causes the inner variable-diameter guide slot 11 to rotate forward, causing the wider side of the guide slot 11 to rotate to the position corresponding to the push rod 9. When the inner wall of the guide groove 11 no longer limits the outer end of the push rod 9, the locking sleeve 4 is rotated forward, causing the push rod 9, which is slidably mounted on the side wall, to rotate forward. The arc-shaped structure at the connection between the push groove 26 and the diversion groove 25 compresses the arc-shaped structure at one end of the push rod 9, causing one end of the push rod 9 to slide out of the push groove 26 and into the diversion groove 25 to perform forward sliding. The other end of the push rod 9 drives the adapter spring 22 to stretch outward. At the same time, the locking sleeve 4 drives the straight groove 32 and the fastening groove 23 opened on the inner side to rotate forward. When the locking sleeve 4 drives the push rod 9 to rotate to the other end of the diversion groove 25, one end of the push rod 9 moves to the position corresponding to one end of the vertical groove 24. The adapter spring 22 drives the push rod 9 to slide and reset, causing the push rod 9 to slide inward.This allows one end of the push rod 9 to insert into one end of the vertical groove 24, which is connected to the other end of the diversion groove 25. Simultaneously, the locking sleeve 4 rotates the straight groove 32 to the position corresponding to the fastening block 8. Then, the locking sleeve 4 is pulled to one side, causing the fastening block 8 to enter the straight groove 32. The locking sleeve 4 then causes the push rod 9 to slide along the vertical groove 24, allowing the push rod 9 to slip out of the vertical groove 24 and the fastening block 8 to slip out of the straight groove 32, thus removing the locking sleeve 4 at this point. Then, the locking rod 6 is pulled in the opposite direction to remove it. Following the same steps, the other corresponding locking rods 6 and locking sleeves 4 are removed in sequence. Finally, the worm gear box assembly 1, along with the base plate 3, can be removed from above the mounting base 2.

[0030] When installing the worm gear box assembly 1, first place the worm gear box assembly 1 on the corresponding position on the mounting base 2, ensuring that the pre-drilled mounting holes on the base plate 3 and the mounting base 2 are concentrically aligned. Then, pass the locking rod 6 through the pre-drilled mounting hole from one side of the mounting base 2, and then re-fit the locking sleeve 4 from the other side of the base plate 3 onto the outside of the locking rod 6, allowing the fastening block 8 to slide into the straight groove 32. One end of the push rod 9, located on the side wall of the locking sleeve 4, slides into the vertical groove 24. When the locking sleeve 4 is fully fitted onto the outside of the locking rod 6, the fastening block 8 moves to one end of the straight groove 32, and the push rod 9 moves to one end of the vertical groove 24. Reverse rotation of the locking sleeve 4 causes the push rod 9 to rotate in the opposite direction. The arc-shaped structure at the connection between the drainage groove 25 and the vertical groove 24 corresponds to the arc-shaped structure at one end of the push rod 9. The compression causes one end of the push rod 9 to slide out of the vertical groove 24 and into the drainage groove 25 for reverse sliding. Simultaneously, the push rod 9 drives the adapter spring 22 connected to the other end to stretch outwards again. At the same time, the locking block 8 enters the locking groove 23 and moves in the reverse direction. When the push rod 9 moves to the position corresponding to the push groove 26, the locking sleeve 4 stops rotating, and the locking block 8 is in its original position inside the locking groove 23. At this time, the adapter spring 22 resets and pulls the push rod 9, causing it to slide inwards and reset. One end of the push rod 9 is reinserted into the push groove 26. Then, the rotating sleeve 7 is rotated in the reverse direction, causing the multiple connecting grooves 10 on one side to rotate in the reverse direction. Simultaneously, the rotating sleeve 7 causes the guide groove 11, which is opened with a variable diameter on the inner side, to rotate in the reverse direction. When the guide groove 11 is fully rotated... During the reset, the narrower inner wall of the guide groove 11 limits the outer end of the push rod 9, preventing it from sliding outward. The push rod 9, in conjunction with the push groove 26, limits the locking rod 6, preventing the locking sleeve 4 and the locking rod 6 from rotating relative to each other. At this time, the rotating sleeve 7 drives the connecting groove 10 to rotate and reset completely, causing the corresponding connecting groove 10 to rotate to the position corresponding to the original locking rod 13. Then, the action plate 14 is rotated forward again, causing the action plate 14 to drive the cooperating block 17 on one side to rotate forward again. Then, the cooperating block 17 drives the cooperating rod 27 on one side to rotate forward again along the cooperating hole 28. The cooperating block 17 and the mating block 5 cooperate again to press the cooperating spring 18. At the same time, the action plate 14 drives the rotating hole 15 and the rotating groove 16 to rotate forward again. When the rotating hole When 15 rotates again to the position concentric with the pressing plate 21, the pressing spring 29 will push the pressing sleeve 19 to drive the inner sliding block 31 to slide and reset along the sliding groove 30. At the same time, the pressing sleeve 19 will drive the pressing rod 20 on one side and the two pressing plates 21 to slide and reset. Due to the bevel design of one end of the pressing sleeve 19 and the arc design of the end of the locking rod 13, one end of the pressing sleeve 19 will gradually push the corresponding end of the locking rod 13 outward. Then the locking rod 13 will rotate in the opposite direction and reset in the connecting frame 12, so that the other end of the locking rod 13 will re-lock into the original connecting groove 10. At this time, the pressing spring 29 is fully reset, and the pressing plate 21 at the top of the pressing rod 20 just moves back to the original side of the action plate 14. Then the action plate 14 is released.The coordinating spring 18 resets, pushing the coordinating block 17 to reverse reset. The coordinating block 17 then drives one side of the coordinating rod 27 to reverse reset along the coordinating hole 28. Simultaneously, the coordinating block 17, through the actuating plate 14, drives the rotating hole 15 and rotating groove 16 to rotate in the opposite direction, resetting them to positions that do not correspond to the pressing rod 20 and pressing plate 21. Then, the pressing rod 20, in conjunction with its top pressing plate 21, supports the pressing sleeve 19 to one side of the actuating plate 14, cooperating with the sliding block 3. The sliding groove 30 limits the movement of the pressing sleeve 19, preventing it from shifting. Then, the pressing sleeve 19, together with the locking rod 13, connecting frame 12, and connecting groove 10, forms a rotation limit on the rotating sleeve 7, preventing accidental rotation and ensuring a secure connection between the locking sleeve 4 and the locking rod 6. Following the same steps, other locking sleeves 4 and locking rods 6 are then fixed in place, achieving tool-free, convenient disassembly and positioning of the double-envelope worm gear box and ensuring its stability after installation.
