Description

Technical Field

[0001] This utility model relates to the field of speed reducers, specifically a speed reducer that can be quickly connected and disassembled. Background Technology

[0002] A speed reducer is an important mechanical transmission device widely used in various industrial equipment and automation systems. Its core function is to increase output torque by reducing the rotational speed, thereby meeting the power requirements under different working conditions. The speed reducer and the motor are core components that work closely together in the mechanical transmission system. The motor converts electrical energy into mechanical energy to provide rotational power, but it usually has a high output speed and low torque, which is difficult to directly meet the high load requirements. By using gears, worm gears and other mechanisms in the speed reducer to reduce the speed and increase the torque, the motor power can be adapted to different working conditions. When the speed reducer and the motor are combined, "low speed and high torque" output can be achieved, while protecting the motor from damage caused by overload or high-speed operation and extending the service life of the equipment.

[0003] However, most traditional speed reducers and motors are connected by multiple bolts, which makes disassembly complicated and cumbersome. Multiple bolts need to be tightened or loosened one by one. Especially in scenarios with limited space or frequent maintenance (such as production lines and automated equipment), the operation efficiency is low. In addition, special tools such as torque wrenches are required, which raises the operation threshold. The bolt specifications must be strictly matched, otherwise the bolts are easy to loosen or be damaged. During the tightening process, the motor and speed reducer shafts may be misaligned, requiring repeated adjustments and increasing installation time. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most traditional speed reducers and motors are connected by multiple bolts, which makes disassembly complicated and cumbersome, requiring each bolt to be tightened or loosened one by one. This is especially problematic in scenarios with limited space or frequent maintenance, resulting in low operational efficiency. This utility model proposes a speed reducer that can be quickly connected and disassembled.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a speed reducer that can be quickly connected and disassembled, including a base plate, a first support plate fixedly connected to one side of the base plate, a speed reducer body slidably inserted into the inner cavity of the first support plate, a motor body provided on one side of the speed reducer body, a docking plate fixedly connected to one side of the speed reducer body and one side of the motor body, and a fixing structure provided on one side of the base plate.

[0006] The fixing structure includes a second support plate, one side of which is fixedly connected to one side of the base plate, and the other side of which is fixedly connected to a connector. A rotating component is rotatably connected to the inner cavity of the connector. A handle is fixedly connected to one end of the rotating component, and a first screw is fixedly connected to the other end. A transmission component is threaded onto the surface of the first screw. A first connecting seat is fixedly connected to the surface of the connector, and a second connecting seat is fixedly connected to the surface of the transmission component. Multiple first and second connecting seats are provided. A first connecting rod is rotatably connected to the inner cavity of each first connecting seat. A second connecting rod is rotatably connected to one end of each first connecting rod. One side of the second connecting rod is rotatably connected to the inner cavity of the second connecting seat, and a pawl is rotatably connected to the other end of the second connecting rod. The inner wall of the pawl engages with the mating plates.

[0007] Preferably, the inner cavity of the claw is slidably connected to an elastic plate, and one side of the elastic plate is attached to one side of the mating plate.

[0008] Preferably, the inner cavity of the transmission component is threadedly connected to a second screw, one end of which is rotatably connected to a first reinforcing plate, and one side of the first reinforcing plate abuts against one side of the motor body.

[0009] Preferably, a first limiting rod is fixedly connected to one side of the first reinforcing plate, and the surface of the first limiting rod is slidably connected to the inner cavity of the transmission component.

[0010] Preferably, a second reinforcing plate is fixedly connected to the surface of the transmission component, and the inner wall of the second reinforcing plate is attached to the surface of the motor body.

[0011] Preferably, an extension plate is fixedly connected to one side of the connector, a third screw is threadedly connected to the inner cavity of the extension plate, a toothed plate is rotatably connected to one end of the third screw, a second limiting rod is fixedly connected to the surface of the toothed plate, and the surface of the second limiting rod is slidably connected to the inner cavity of the extension plate.

[0012] Preferably, a toothed ring is fixedly connected to the surface of the rotating component, and the teeth of the toothed plate and the teeth of the toothed ring mesh with each other.

[0013] The advantages of this utility model are:

[0014] This invention uses a rotating component to drive the handle to rotate along the inner cavity of the connector. Simultaneously, the rotating component drives the first screw to rotate. A transmission component is threaded onto the surface of the first screw. This transmission component is constrained to a first connecting seat on the surface of the connector via a first connecting rod and a second connecting rod. As the first screw rotates, it drives the transmission component to move laterally. Simultaneously, the transmission component moves towards the connector, causing the second connecting rod to rotate along the second connecting seat and push the first connecting rod at one end. The other end of the second connecting rod moves closer to the mating plate. The continuous movement of the second connecting rod towards the mating plate causes the pawl to engage with the two sets of mating plates, thus achieving rapid connection and disassembly between the reducer body and the motor body. This solves the problem of traditional reducers and motors being connected by multiple bolts, resulting in complex and cumbersome disassembly methods that require tightening or loosening multiple bolts one by one, especially in space-constrained or frequently maintained scenarios, leading to low operational efficiency.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a speed reducer that can be quickly connected and disassembled. (Refer to...) Figures 1 to 3 A speed reducer that can be quickly connected and disassembled includes a base plate 1, a first support plate 2 fixedly connected to one side of the base plate 1, a speed reducer body 3 slidably inserted into the inner cavity of the first support plate 2, a motor body 4 provided on one side of the speed reducer body 3, a docking plate 5 fixedly connected to one side of the speed reducer body 3 and one side of the motor body 4, and a fixing structure 6 provided on one side of the base plate 1.

[0025] The fixing structure 6 includes a second support plate 601. One side of the second support plate 601 is fixedly connected to one side of the base plate 1. A connector 602 is fixedly connected to the other side of the second support plate 601. A rotating component 603 is rotatably connected to the inner cavity of the connector 602. A handle 604 is fixedly connected to one end of the rotating component 603, and a first screw 605 is fixedly connected to the other end of the rotating component 603. A transmission component 606 is threadedly connected to the surface of the first screw 605. A first connecting seat 607 is fixedly connected to the surface of the connector 602, and a second connecting seat 607 is fixedly connected to the surface of the transmission component 606. Multiple first connecting seats 607 and second connecting seats 608 are provided. A first connecting rod 609 is rotatably connected to the inner cavity of each first connecting seat 607. One end of the first connecting rod 609 is rotatably connected to a second connecting rod 610. One side of the second connecting rod 610 is rotatably connected to the inner cavity of the second connecting seat 608, and the other end of the second connecting rod 610 is rotatably connected to a pawl 611. The inner wall of the pawl 611 engages with the mating plates 5. In this quick-connect and disassembleable reducer, the base plate 1 plays a major supporting role. An installation device is fixedly connected to the outer side of the reducer body 3. The gearbox body 3 is quickly connected to the first support plate 2 via the mounting plate. The gearbox body 3 and the motor body 4 are first connected, and simultaneously, the connecting plate 5 is fitted together. The second support plate 601 and the connecting piece 602 in the fixing structure 6 provide the main support. The rotating part 603 can be rotated along the inner cavity of the connecting piece 602 via the handle 604. Simultaneously, the rotation of the rotating part 603 drives the first screw 605 to rotate synchronously. The surface of the first screw 605 is threadedly connected to a transmission part 606, which is connected via the first... A first connecting rod 609 and a second connecting rod 610 are defined on the surface of the connector 602 by a first connecting seat 607. When the first screw 605 rotates, it drives the transmission member 606 to move laterally. When the transmission member 606 moves toward the connector 602, it drives the second connecting rod 610 to rotate along the second connecting seat 608 and pushes the first connecting rod 609 at one end. The other end of the second connecting rod 610 moves closer to the docking plate 5. The second connecting rod 610 continues to move closer to the docking plate 5 so that the claw 611 engages with the two sets of docking plates 5, thereby realizing the quick connection and disassembly between the reducer body 3 and the motor body 4.

[0026] Reference Figure 3 and Figure 4 The inner cavity of the claw 611 is slidably connected to an elastic plate 7. One side of the elastic plate 7 is attached to one side of the docking plate 5. Through the elastic plate 7, the elastic plate 7 can be elastically supported by spring. When the claw 611 engages with the two sets of docking plates 5, it squeezes the elastic plate 7. The elastic plate 7 supported by the spring can further improve the firmness of the engagement between the claw 611 and the docking plate 5.

[0027] Reference Figure 3The inner cavity of the transmission component 606 is threadedly connected to a second screw 8. One end of the second screw 8 is rotatably connected to a first reinforcing plate 9. One side of the first reinforcing plate 9 abuts against one side of the motor body 4. One side of the first reinforcing plate 9 is fixedly connected to a first limiting rod 10. The surface of the first limiting rod 10 is slidably connected to the inner cavity of the transmission component 606. Through the first reinforcing plate 9, the first reinforcing plate 9 is connected to the transmission component 606 via the second screw 8. The first limiting rod 10 can limit the first reinforcing plate 9. When the second screw 8 rotates, it can drive the first reinforcing plate 9 to move laterally. The abutment of one side of the first reinforcing plate 9 against one side of the motor body 4 can further improve the firmness of the connection between the reducer body 3 and the motor body 4 from the side.

[0028] Reference Figure 3 A second reinforcing plate 11 is fixedly connected to the surface of the transmission component 606. The inner wall of the second reinforcing plate 11 is attached to the surface of the motor body 4. Through the second reinforcing plate 11, the bottom surface of the motor body 4 can be supported. When the fixed structure 6 releases the connection between the reducer body 3 and the motor body 4, the transmission component 606 moves closer to the motor body 4. At the same time, the contact area between the second reinforcing plate 11 and the motor body 4 increases, ensuring the stability of the motor body 4 when the reducer body 3 and the motor body 4 are disassembled.

[0029] Reference Figure 5 An extension plate 12 is fixedly connected to one side of the connector 602. A third screw 13 is threadedly connected to the inner cavity of the extension plate 12. A toothed plate 14 is rotatably connected to one end of the third screw 13. A second limiting rod 15 is fixedly connected to the surface of the toothed plate 14. The surface of the second limiting rod 15 is slidably connected to the inner cavity of the extension plate 12. A toothed ring 16 is fixedly connected to the surface of the rotating component 603. The teeth of the toothed plate 14 and the teeth of the toothed ring 16 mesh with each other. Through the toothed plate 14 and the toothed ring 16, the toothed ring 16 and the rotating component 603 are coaxially fixedly connected. While rotating component 603 rotates, it can drive gear ring 16 to rotate. Gear plate 14 is connected to extension plate 12 through third screw 13 and second limit rod 15. When third screw 13 rotates along extension plate 12, it can drive gear plate 14 to rise and fall. Gear plate 14 ensures the stability of rising and falling under the limitation of second limit rod 15. When gear plate 14 meshes with gear ring 16, it can limit the position of rotating component 603, avoid accidental rotation of rotating component 603 as much as possible, and ensure the firmness of fixed structure 6 when fixing reducer body 3 and motor body 4.

[0030] Working principle: The base plate 1 provides the main support. A mounting plate is fixedly connected to the outside of the reducer body 3. The reducer body 3 is quickly connected to the first support plate 2 via the mounting plate. The reducer body 3 and the motor body 4 are first connected. Simultaneously, the connecting plate 5 fits together with the reducer body 3 and motor body 4. The second support plate 601 and connecting piece 602 in the fixed structure 6 provide the main support. The rotating part 603 can be rotated along the inner cavity of the connecting piece 602 via the handle 604. Simultaneously, the first screw 605 is driven to rotate synchronously. A transmission component 606 is threadedly connected to the surface of the first screw 605. The transmission component 606 is limited to the first connecting seat 607 on the surface of the connecting member 602 via the first connecting rod 609 and the second connecting rod 610. As the first screw 605 rotates, it drives the transmission component 606 to move laterally. As the transmission component 606 moves toward the connecting member 602, it drives the second connecting rod 610 to rotate along the second connecting seat 608 and pushes the first connecting rod 609 at one end. The other end of the second connecting rod 610 moves toward the mating plate 5. As the second connecting rod 610 continues to move closer to the docking plate 5, the claw 611 engages with the two sets of docking plates 5. Simultaneously, the claw 611 engages with the two sets of docking plates 5, pressing against the elastic plate 7. The elastic plate 7, supported by a spring, further enhances the firmness of the engagement between the claw 611 and the docking plate 5. The first reinforcing plate 9 is connected to the transmission component 606 via the second screw 8, and the first limiting rod 10 can limit the first reinforcing plate 9. As the second screw 8 rotates, it can drive the first reinforcing plate 9 to move laterally. One side of the first reinforcing plate 9 is connected to the motor body 4. The side abutting can further improve the firmness of the connection between the reducer body 3 and the motor body 4 from the side. The second reinforcing plate 11 can support the bottom surface of the motor body 4. When the fixed structure 6 releases the connection between the reducer body 3 and the motor body 4, the transmission component 606 moves closer to the motor body 4. At the same time, the contact area between the second reinforcing plate 11 and the motor body 4 increases, ensuring the stability of the motor body 4 when the reducer body 3 and the motor body 4 are disassembled, thereby realizing the quick connection and disassembly between the reducer body 3 and the motor body 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
