[0002] The speed reducer plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator. The main components include a reducer, a driving motor, and a frame. The traditional frame structure is single and simple in function. That is to say, it is difficult to adjust adaptively according to the installation requirements of motors of different model sizes during actual use. Then, the model and size of the matched motor are also fixed, and the bolt fastening method is adopted. In this process, the user needs to align the screw holes, insert the bolts, control the bolt torque, and tighten the bolts in the specified front-back order, which increases the workload of the user and reduces the work efficiency.

[0003] In view of the above problems, the utility model is improved. Summary of the Invention

[0004] The utility model provides a speed reducer with an adjustable frame, which solves the above problems existing in the prior art during use.

[0005] The technical solution of the utility model is realized as follows: A speed reducer with an adjustable frame includes a frame. A fixed guide rail is fixedly installed at the top of the frame. Chutes are opened on both sides of the fixed guide rail. A limiting rod is fixedly installed at one end inside the chute. A pin is slidably installed on the surface of the limiting rod. The top of the pin is fixedly installed with a clamping arm located at the top of the fixed guide rail. A clamping strip is fixedly connected to the inner wall of the clamping arm. Locking members are rotatably installed on both sides of the top of the frame and located below the fixed guide rail. The locking members are adapted to the pins. An external gear ring is fixedly installed on the surface of the locking member. An internal gear ring is sleeved outside the external gear ring. One side of the internal gear ring is fixedly installed on the frame.

[0006] For the speed reducer with an adjustable frame as described above in the utility model, further: A torsion block is fixedly installed on the surface of the locking member and located below the external gear ring.

[0008] The reducer with an adjustable frame as described above for the present utility model further comprises: a socket block is fixedly installed on the output shaft of the motor, and a mounting block located between two clamping arms is fixedly installed on the surface of the socket block.

[0009] The reducer with an adjustable frame as described above for the present utility model further comprises: a clamping groove is formed on the surface of the mounting block, and both clamping bars are adapted to the clamping groove.

[0010] The reducer with an adjustable frame as described above for the present utility model further comprises: a mounting plate is fixedly connected to the bottom of the frame, and a reducer adapted to the output shaft of the motor is detachably installed at the bottom of the inner cavity of the frame.

[0014] 2. Through the setting of the convex strip and the torsion block in the present utility model, the convex strip is arranged on the surface of the torsion block, making the surface of the torsion block uneven. In this way, when the user rotates the torsion block, the friction force between the torsion block and the user's limb can be increased, avoiding the situation of hand slipping and providing assistance for the user's use.

[0015] 3. Through the setting of the motor and the jack in the present utility model, the motor is used to generate power to realize the normal operation of the reducer.

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figures 1-5 drawings in the embodiments of the present utility model.

Embodiment

[0027] A reducer with an adjustable frame includes a frame 1. A fixed guide rail 2 is fixedly installed at the top of the frame 1. Chutes 3 are opened on both sides of the fixed guide rail 2. A limit rod 4 is fixedly installed at one end inside the chute 3. A bolt 5 is slidably installed on the surface of the limit rod 4. The top of the bolt 5 is fixedly installed with a clamping arm 6 located above the fixed guide rail 2. A clamping strip 7 is fixedly connected to the inner wall of the clamping arm 6. Locking parts 8 located below the fixed guide rail 2 are rotatably installed on both sides of the top of the frame 1. The locking parts 8 are adapted to the bolts 5. An external gear ring 9 is fixedly installed on the surface of the locking parts 8. An internal gear ring 10 is sleeved outside the external gear ring 9. One side of the internal gear ring 10 is fixedly installed on the frame 1.

[0028] The specific usage process is as follows: When installing the motor 11, the user first adjusts the two clamping arms 6 outward so that the distance between the two clamping arms 6 can meet the installation requirements of the motor 11. When adjusting, the user first rotates the torsion block 15, and the torsion block 15 can drive the locking member 8 to rotate. Among them, the convex strips are arranged on the surface of the torsion block 15, making the surface of the torsion block 15 uneven. In this way, when the user rotates the torsion block 15, the friction between the torsion block 15 and the user's limb can be increased, avoiding the situation of hand slipping, providing assistance for the user's use. At the same time, the locking member 8 also drives the outer gear ring 9 to rotate, and the outer gear ring 9 rotates within the inner gear ring 10. And the outer surface of the outer gear ring 9 is provided with convex teeth. Similarly, the inner wall of the inner gear ring 10 is also provided with convex teeth adapted to the outer gear ring 9. In this way, when the outer gear ring 9 rotates, there will be a "click click click" sound, which can provide a "warning" for the user, enabling the user to accurately know whether the opening on the locking member 8 is on the moving track of the bolt 5, so as to ensure the normal progress of the adjustment work. The specific situation depends on the actual work. It should be noted that since the outer gear ring 9 and the inner gear ring 10 are in a meshing state, the materials selected for the outer gear ring 9 and the inner gear ring 10 should be materials with toughness to ensure that the outer gear ring 9 can rotate normally within the inner gear ring 10 when the inner gear ring 10 does not move. This is the prior art and will not be elaborated in the text. After the opening on the locking member 8 rotates to be on the same moving track as the bolt 5, it should be noted that the bolt 5 slides on the limiting rod 4 and also slides within the sliding groove 3. At this time, the clamping arm 6 can be moved outward to expand. The bolt 5 will also move along with the clamping arm 6. The bolt 5 at the current position will move out of the locking member 8, and at the same time, the corresponding bolt 5 will enter the locking member 8. In this way, when the distance between the two clamping arms 6 does not meet the installation requirements, continue to move the clamping arm 6, and the bolt 5 will move out of the locking member 8, and the subsequent bolt 5 will follow and enter the locking member 8 until the adjustment of the clamping arm 6 is completed. At this time, the bolt 5 at the corresponding position will be stuck in the locking member 8. Then the user rotates the torsion block 15 to drive the locking member 8 to rotate, and the opening on the locking member 8 rotates 90 degrees. In this way, the bolt 5 that enters the locking member 8 will be restricted by the locking member 8 and cannot move anymore, so as to fix the clamping arm 6 in the current position. It should be noted that when the position of the clamping arm 6 is adjusted, the output shaft of the motor 11 can be inserted into the machine frame 1 until the output shaft of the motor 11 is inserted and installed on the reducer 14. Then, move the two clamping arms 6 towards each other and clamp them on the mounting block 12. The clamping strips 7 on the clamping arm 6 will also be stuck into the clamping grooves 16 on the mounting block 12, so as to fix the mounting block 12 and also fix the motor 11. Finally, the matching assembly of the machine frame 1 and the motor 11 is completed, and the assembly of the reducer is also completed. In this way, both the compactness, firmness, and stability of the reducer assembly are ensured, and the assembly efficiency of the reducer is improved, providing convenience for the user's work and use.

[0029] Therefore, an adjustable frame structure design is adopted, and the traditional bolt connection structure is improved into a clamp arm structure that can be flexibly expanded and adjusted. The flexibility of the clamp arm can be expanded to achieve the installation and fixation of motors of different sizes, which saves a lot of time spent in the traditional bolt installation process, simplifies the steps of traditional bolt installation, improves the efficiency of reducer assembly, and provides convenience for users' work.

[0031] Specifically, the convex strips and the twist block 15 are arranged such that the convex strips are arranged on the surface of the twist block 15 so that the surface of the twist block 15 is uneven, so that when the user rotates the twist block 15, the friction between the twist block 15 and the user's limbs can be increased, thereby avoiding hand slippage and providing assistance for the user.

For example, it can be installed with a pin key structure, or it can be connected with bolts. This is the prior art, and the specific detailed structure is not described in detail in the text. The installation block 12 and the slot 16 are used to dock with the clamp arm 6 and the clamping strip 7 for installation. In this way, when the two clamp arms 6 are combined, the two clamping strips 7 can also be inserted into the slot 16, so that the rack 1 is installed and fixed on the rack 1 and the fixed guide rail 2, and it can also be quickly disassembled, which provides convenience for the user's disassembly and assembly work.

[0036] A mounting plate 13 is fixedly connected to the bottom of the frame 1 , and a reducer 14 adapted to the output shaft of the motor 11 is detachably mounted at the bottom of the inner cavity of the frame 1 .

[0037] Specifically, the mounting plate 13 and the speed reducer 14 are provided.

The speed reducer 14 is used to assist the motor 11 in achieving the function of speed reduction, ensuring that the speed reduction can meet the user's usage requirements and providing convenience for the user's work.

[0038] The top of the mounting plate 13 is provided with pre-installation holes distributed in a circular array, and connecting bolts 18 are inserted into the interiors of the pre-installation holes.

[0039] Specifically, the pre-installation holes and the connecting bolts 18 are provided. The pre-installation holes are used for inserting and installing the connecting bolts 18. In this way, the frame 1 and the motor 11 can be installed and fixed in a suitable position through the connecting bolts 18, ensuring the normal operation of the speed reducer and providing convenience for the user's work.
