[0013] 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 protection scope of the present utility model.
[0014] Please see Figures 1-4 This utility model provides a technical solution: a hub reducer that is easy to install, including a housing 1 and a housing 2. The bottom of both sides of the housing 1 is fixedly connected to an outer fixing seat 3, and the top of both sides of the housing 2 is fixedly connected to an outer fixing seat 4. A positioning groove 5 is formed at the center of the top of the outer fixing seat 4. A positioning plate 6 is fixedly connected to the center of the bottom of the outer fixing seat 3. The bottom of the positioning plate 6 extends through the interior of the positioning groove 5 and engages with it. Fixing grooves 9 are formed near the bottom of both sides of the positioning plate 6. Movable grooves 10 are formed near both sides inside the outer fixing seat 4. A movable groove 11 is formed inside the outer fixing seat 4 corresponding to the bottom of the movable groove 10. A movable horizontal plate 14 is slidably connected to one side of the movable groove 11. A movable vertical plate 12 is fixedly connected to the top of the movable horizontal plate 14. The top of the movable vertical plate 12 extends through the interior of the movable groove 10 and slidably connects to it. Fixing plates 13 are fixedly connected to the center of opposite sides of the two movable vertical plates 12.
[0015] A limiting groove 7 is formed at the center of the bottom end of the positioning plate 6. A limiting plate 8 is fixedly connected to the center of the bottom of the positioning groove 5. The top of the limiting plate 8 extends through the interior of the limiting groove 7 and engages with the limiting groove 7.
[0016] The side of the fixing plate 13 away from the movable vertical plate 12 extends into the interior of the fixing groove 9 and engages with the fixing groove 9.
[0017] Limiting rods 21 are fixedly connected to the top and bottom positions of the movable groove 10. The limiting rods 21 are sleeved and slidably connected to the movable vertical plate 12. A support rod 16 is fixedly connected to the center of the movable groove 11. A return spring 17 is sleeved on the surface of the support rod 16. The two sides of the return spring 17 are fixedly connected to the inner wall of the movable groove 11 and the movable horizontal plate 14, respectively.
[0018] The bottom of the external fixing seat 3 is provided with positioning grooves 18 on both sides, and the top of the external fixing seat 4 is fixedly connected with positioning plates 19 on both sides. The top of the positioning plates 19 extends into the interior of the positioning grooves 18 and engages with the positioning grooves 18.
[0019] One side of the external fixing seat 3 is threaded with a fixing bolt 20, and one side of the fixing bolt 20 penetrates into the interior of the two positioning plates 19 and is threadedly connected to the positioning plates 19.
[0020] A push plate 15 is fixedly connected to the bottom of the movable horizontal plate 14. The bottom of the push plate 15 extends through to the outside of the outer fixed seat 2 4 and is slidably connected to the outer fixed seat 2 4.
[0021] Working principle: The operator aligns the outer fixing seat 3 at the bottom of housing 1 with the outer fixing seat 4 at the top of housing 2, aligning the positioning plate 6 at the bottom of outer fixing seat 3 with and inserting it into the positioning groove 5 at the top of outer fixing seat 4. After the positioning plate 6 is fully inserted, the limiting groove 7 at its bottom engages with the limiting plate 8 at the bottom of positioning groove 5, completing the initial vertical positioning of housing 1 and housing 2. Simultaneously, the positioning groove 18 at the bottom of outer fixing seat 3 engages with the positioning plate 19 at the top of outer fixing seat 4. This auxiliary positioning structure further enhances the positioning accuracy between housing 1 and housing 2, ensuring accurate relative positions in the horizontal direction. After the positioning plate 6 engages with the positioning groove 5, the operator pushes the push plate 15 outside outer fixing seat 4, causing the movable horizontal plate 14 to slide within the movable groove 11. The sliding of plate 14 further drives the movable vertical plate 12 to slide within the movable slot 10, while simultaneously compressing the return spring 17 within the movable slot 2 11. When the positioning plate 6 is fully inserted into the positioning slot 5, the operator releases the push plate 15. The elastic restoring force of the return spring 17 pushes the movable horizontal plate 14 to slide in the opposite direction, thereby driving the fixing plate 13 on the movable vertical plate 12 to move towards the fixing slots 9 on both sides of the positioning plate 6. The fixing plate 13 eventually penetrates into the interior of the fixing slot 9 and engages with the fixing slot 9, completing the elastic fixation between housing 1 and housing 2. After the fixing plate 13 engages with the fixing slot 9, the operator uses tools to tighten the fixing bolt 20 on one side of the outer fixing seat 3, so that it penetrates into the interior of the two positioning plates 2 19 and achieves a threaded connection with the positioning plates 2 19. This secondary fixing measure further enhances the fixing effect between housing 1 and housing 2, preventing fixation failure due to vibration or impact.
[0022] In summary, this easy-to-install hub reducer achieves initial vertical positioning of housing 1 and housing 2 by precisely engaging a positioning plate 6 at the bottom of the outer fixed base 3 with a positioning groove 5 at the top of the outer fixed base 4. This design effectively avoids deviations caused by inaccurate manual alignment in traditional installations, ensuring the precision of gear meshing within the reducer, reducing noise and vibration, and extending the equipment's service life. Furthermore, a limiting groove 7 at the bottom of the positioning plate 6 closely cooperates with the limiting plate 8 at the bottom of the positioning groove 5, forming a double positioning mechanism. This design not only enhances installation stability but also improves the overall performance of the reducer. The limiting mechanism prevents relative displacement between the housings, improving the reliability of the equipment under complex working conditions. By utilizing the movable vertical plate 12 and fixed plate 13 in movable slot 10 and movable slot 2 11, combined with the elastic action of the return spring 17, the fixed plate 13 and fixed slot 9 are automatically engaged and released. Operators only need to push the push plate 15 to easily complete the installation and disassembly of the reducer, greatly shortening maintenance time and reducing labor costs. By setting the limiting rod 21 in movable slot 10, the sliding of movable vertical plate 12 is precisely guided, avoiding fixation failure caused by vibration or impact, and ensuring the long-term reliability of the fixing mechanism.
