[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, a gear, and a worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

[0003] However, in the prior art, when some reducers are in use, in order to keep them in a stable state, most reducers will fix the four corners with bolts to prevent them from shaking during operation. However, after long-term use, the interior of the reducer also needs maintenance. However, at this time, because the four corners are fixed with bolts, it may take a long time to dismantle the reducer before subsequent maintenance and use. For this reason, we propose a reducer that is easy to load and unload to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: a reducer that is easy to load and unload and maintain, including a base 1, a reducer body 2, a cover frame 3 and a fixing plate 11. The reducer body 2 is placed on the upper end of the outer wall of the base 1, and the cover frame 3 is arranged on the upper end of the outer wall of the base 1. A sleeve 5 is fixedly connected to the middle of the inner wall of the cover frame 3, and a buffer component is arranged in the middle of the sleeve 5. The buffer component is used to stabilize the use of the reducer body 2. The left and right sides of the upper end of the base 1 are fixedly connected to the fixing plate 11, and a slide groove 12 is opened in the middle of the fixing plate 11.

[0020] Furthermore, a slot is provided at the upper end of the outer wall of the base 1 which is compatible with the outer wall corners of the cover frame 3. Pull rods 4 are fixedly connected to the left and right sides of the upper end of the cover frame 3, and the outer wall corners of the pull rods 4 are all set as arc-shaped corners. This structure can be adapted to reducer bodies 2 of different heights for use, and the cover frame 3 can be directly used through the pull rods 4.

[0021] Furthermore, the buffer assembly includes a slot 6, a slot 6 is provided in the middle of the interior of the sleeve 5, and a spring 7 is provided in the middle of the inner wall of the slot 6, a damping block 8 is abutted against the outer wall end of the spring 7, and the outer wall surface of the damping block 8 is adapted to the inner wall surface of the slot 6, a telescopic rod 9 is fixedly connected to the outer wall of the damping block 8, and a push plate 10 is fixedly connected to the outer wall end of the telescopic rod 9. This structure can be used by rubbing the damping block 8 on the inner wall of the slot 6, thereby reducing the shaking and vibration caused by the reducer body 2 during use, and generating a partial pressing effect to stabilize the normal use of the reducer body 2.

[0022] Furthermore, a screw rod 13 is inserted in the middle of the inner wall of the slide groove 12, and a turning handle 14 is provided at the outer wall end of the screw rod 13. The outer wall surface of the screw rod 13 is connected with a screw sleeve 15 through a thread, and the outer wall of the screw sleeve 15 is fixedly connected to the inner wall of the slide groove 12. The inner end of the screw rod 13 is fixedly connected to a limiting block 16, and the outer wall end of the limiting block 16 is set as an arc surface. Limiting grooves 17 are vertically equidistantly provided at the left and right ends of the cover frame 3, and the inner wall of the limiting groove 17 is adapted to the outer wall of the limiting block 16. After the position of the cover frame 3 is adapted, this structure can be stably adapted through the threaded movement of the screw rod 13, thereby stabilizing the placement and use of the cover frame 3.

[0023] Furthermore, a soft pad is provided on the outer wall surface of the push plate 10, and the outer wall surface of the push plate 10 is in contact with the upper end of the outer wall of the reducer body 2. The outer wall surface of the cover frame 3 and the outer wall surface of the fixed plate 11 are equidistantly provided with anti-slip strips 18, and the two sets of anti-slip strips 18 are adapted to each other. This structure can reduce damage to the outside of the reducer body 2 during use.

[0024] Furthermore, the outer wall surface of the turning handle 14 is annularly and equidistantly provided with anti-skid protrusions, and the outer wall surfaces of the turning handle 14 and the outer wall surfaces of the pull rod 4 are smooth without edges and corners. This structure can avoid partial damage caused by the edges and corners between the structures during use.

[0025] Working principle: When in use, the reducer body 2 can be placed on the outer wall of the base 1 through the base 1, and then the cover frame 3 is adapted and placed on the outer wall surface of the reducer body 2 through the pull rod 4, and when placing it, the push plate 10 will first contact the outer wall surface of the reducer body 2. At this time, different forces can be used to stabilize its use according to different reducer bodies 2, and after the push plate 10 is fitted, the spring 7 on the inner wall of the slot 6 will be squeezed through the damping block 8, so that the restoring force of the spring 7 after being compressed can stably place the reducer body 2 on the outer wall of the base 1, and with subsequent use, the friction between the damping block 8 and the inner wall of the slot 6 can partially resist the shaking of the reducer body 2 during use. The cover frame 3 is preferably placed on the outer wall of the reducer body 2 to prevent it from being damaged. When placed, the cover frame 3 will be in a vertical position to move in the vertical direction. After the cover frame 3 is adapted, it can be used through the fixing plates 11 on both sides, so that the turning handle 14 is turned and the screw 13 is driven to move the limit block 16 in the horizontal direction through threaded movement. When moving, it will be adapted to the limit groove 17 on the outer wall of the cover frame 3, thereby stabilizing the use position of the cover frame 3. At the same time, the friction force is adapted through two sets of anti-slip strips 18. When the reducer body 2 needs to be taken out for maintenance later, the cover frame 3 can be directly separated from the outer wall of the reducer body 2 by turning the turning handle 14, thereby facilitating subsequent use. The above is the entire working principle of the utility model.
