[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It can reduce the speed and transmit torque by meshing the gear with fewer teeth on the input shaft of the speed reducer with the large gear on the output shaft of a motor, internal combustion engine, or other high-speed rotating power source. Its purpose is to reduce the speed and increase the torque. It has a wide variety of types and models, and different types have different uses. A valve speed reducer is a type of speed reducer, mainly used to control the opening and closing of valves.

[0003] In the prior art, in order to ensure the normal operation performance of the speed reducer, regular maintenance work is usually carried out on the speed reducer. When it is necessary to repair the parts inside the speed reducer, the connecting side plate of the speed reducer needs to be disassembled. Usually, screws are used to connect the housing and the connecting side plate. Therefore, when disassembling and assembling between the housing and the connecting side plate, appropriate tools such as screwdrivers are required to carry out the operation smoothly. And if the maintenance personnel forget to bring tools or bring the wrong tools, it may affect the maintenance work of the speed reducer, which is rather inconvenient.

The role of the drawings is to supplement the description in the text part of the specification, enabling people to visually and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0026] Referring to Figure 1-7 , in an embodiment of the utility model, a valve speed reducer convenient for maintenance includes a bottom plate 1. A speed reducer housing 2 is fixedly connected to the upper surface of the bottom plate 1. A connecting side plate 3 is movably connected to the speed reducer housing 2. Two positioning blocks 4 are fixedly connected to the connecting side plate 3. Two docking blocks 5 are fixedly connected to the speed reducer housing 2. Positioning grooves 6 are formed in both of the two docking blocks 5. Four connecting blocks 7 are fixedly connected to the connecting side plate 3. Connecting shafts 8 are rotatably connected to the inner surfaces of the four connecting blocks 7. Moving plates 9 are fixedly connected to the four connecting shafts 8. Four inserting blocks 10 are fixedly connected to the speed reducer housing 2. Insertion slots 11 are formed in the four moving plates 9. A plurality of connecting grooves 12 are formed in the bottom plate 1. A connecting flange 13 is arranged on the speed reducer housing 2. The outer surface of the positioning block 4 is movably connected to the positioning groove 6. The outer surface of the inserting block 10 is movably connected to the insertion slot 11. The side surfaces of the connecting blocks 7 are respectively in contact with the speed reducer housing 2 and the connecting side plate 3. The inner surface of the moving plate 9 is in contact with the connecting block 7.

[0027] Two limiting blocks 14 are fixedly connected to the speed reducer housing 2. Guide rods 15 are fixedly connected to the inner surfaces of the two limiting blocks 14. Sliders 16 are slidably connected to the outer surfaces of the two guide rods 15. Two fixing rods 17 are fixedly connected to each of the two sliders 16. Fixing grooves 18 are formed in the four moving plates 9. The same concave block 19 is fixedly connected to the corresponding two fixing rods 17. The outer surface of the fixing rod 17 is movably connected to the fixing groove 18. The side surface of the concave block 19 is in contact with the limiting block 14. A spring 20 is slidably sleeved on the outer surface of the guide rod 15. One end of the spring 20 is fixedly connected to the lower surface of the slider 16. The end of the spring 20 away from the slider 16 is fixedly connected to the bottom inner wall of the limiting block 14. The number of the springs 20 is two and they are distributed left and right. A chute 21 is formed in the limiting block 14. The outer surface of the slider 16 is slidably connected to the chute 21.

[0028] Working principle: When it is necessary to repair the parts inside the bottom plate 1, pull down the concave block 19, so that the moving concave block 19 can drive the fixed rod 17 and the slider 16 to move simultaneously. And during the movement of the slider 16, it will gradually compress the spring 20, so that the spring 20 is in a tense state. When the moving fixed rod 17 disengages from the fixed slot 18 and does not affect the flipping of the movable plate 9, flip the movable plate 9, so that the movable plate 9, the slot 11 and the fixed slot 18 are flipped around the connecting shaft 8 as the central axis. When the flipped slot 11 disengages from the plug 10 and the flipped fixed slot 18 no longer corresponds to the fixed rod 17, release the concave block 19, so that the spring 20 is no longer restricted by the tensile force and rebounds. Then the rebounding spring 20 can drive the slider 16 and the fixed rod 17 to move back to their original positions. Then repeat the above operation on the other side to release the fixation between the reducer housing 2 and the connecting side plate 3. Then pull up the connecting side plate 3, and the connecting side plate 3 and the structures on the connecting side plate 3 can be removed from the reducer housing 2, thus realizing the disassembly between the reducer housing 2 and the connecting side plate 3, and then the parts inside the reducer housing 2 can be repaired. When the parts inside the reducer housing 2 are repaired, insert the positioning block 4 into the positioning slot 6 on the docking block 5, and then pull down the concave block 19, so that the moving concave block 19 drives the fixed rod 17 and the fixed slot 18 to move while making the spring 20 in a tense state. When the moving fixed rod 17 does not affect the flipping of the movable plate 9, flip the movable plate 9 in the reverse direction, so that the movable plate 9 and the structures on the movable plate 9 are flipped in the reverse direction. When the flipped slot 11 is inserted into the plug 10, the connection and fixation between the reducer housing 2 and the connecting side plate 3 are completed. When the flipped movable plate 9 contacts the reducer housing 2, the fixed slot 18 can correspond to the fixed rod 17. Then release the pulled concave block 19, so that the spring 20 rebounds, and the rebounding spring 20 drives the slider 16 and the fixed rod 17 to move. When the moving fixed rod 17 enters the fixed slot 18, the fixation of the movable plate 9 is completed, and then the slot 11 will not disengage from the plug 10, improving the stability after the connection between the reducer housing 2 and the connecting side plate 3.
