Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 6 shown, the present utility model provides a swing reducer with a corner mechanism, including:

[0026] Base 1, and a rotating block 2 is movably sleeved inside the base 1;

[0027] A rotating mechanism, which is arranged inside the outer surface of the rotating block 2;

[0028] Among them, the rotating mechanism includes a tooth ring 3. The inside of the tooth ring 3 is fixedly sleeved with the inside of the outer surface of the rotating block 2. The outer surface of the tooth ring 3 is meshed with a gear 4. The outer surface of the gear 4 is movably connected with the inside of the base 1. The outer surface of the gear 4 is movably connected with a stop block 5. The outer surface of the stop block 5 is fixedly connected with the inside of the base 1. A round block 6 is movably sleeved inside the bottom end of the gear 4. A spring 7 is fixedly installed at the bottom end of the round block 6. The bottom end of the spring 7 is fixedly connected with the bottom end inside the base 1.

[0029] Due to the design of the stopper 5, it will block the rotation of the gear 4. Since the gear 4 is meshed and connected with the gear ring 3, when the gear 4 is in a blocked state, it will block the rotation of the gear ring 3. When the gear 4 moves downward along the inside of the base 1, at this time the gear 4 will cancel the contact with the stopper 5 during the downward movement, and then the stopper 5 will release the blocking effect on the rotation of the gear 4. At the same time, the spring 7 will be in a compressed state. Due to the design of the spring 7, it will have a good reset effect on the movement of the gear 4. When the gear 4 rotates, at this time the gear 4 will drive the rotating block 2 to rotate along the inside of the base 1 through the gear ring 3.

[0030] Among them, a round shaft 8 is fixedly installed at the top end of the gear 4. The bottom end of the outer surface of the round shaft 8 is movably sleeved inside the front of the top end of the base 1, and a handle 9 is fixedly installed at the top end of the round shaft 8.

[0031] Since the round shaft 8 is movably sleeved inside the front of the top end of the base 1, the round shaft 8 can only move upward along the inside of the top end of the base 1. Due to the design of the handle 9, it enables the operator to drive the round shaft 8 to rotate through the handle 9, and then the round shaft 8 will drive the gear 4 to rotate.

[0032] Among them, a bracket 10 is fixedly installed at the top end of the rotating block 2, a rotary reducer body 11 is fixedly installed at the top end of the bracket 10, a long shaft 12 is movably installed inside the rotary reducer body 11, and a first rotating block 13 is fixedly installed at the right end of the long shaft 12.

[0033] When the first rotating block 13 rotates, it will drive the long shaft 12 to rotate. When the long shaft 12 rotates, at this time the rotary reducer body 11 will be in an operating state.

[0034] Among them, a fixing plate 14 is fixedly installed at the bottom right side of the front of the rotary reducer body 11. A screw rod 15 is movably sleeved inside the right end of the fixing plate 14. A rotating plate 16 is fixedly sleeved at the rear end of the screw rod 15, and the front of the rotating plate 16 is movably connected to the rear of the fixing plate 14.

[0035] Since the screw rod 15 is movably sleeved inside the fixing plate 14, the screw rod 15 can rotate along the inside of the fixing plate 14. When the screw rod 15 rotates, at this time the rotating plate 16 will be driven by the screw rod 15 to rotate.

[0036] Among them, a screwing block 17 is threadedly sleeved on the outer surface of the screw rod 15, and the back of the screwing block 17 is movably connected to the front of the fixing plate 14.

[0037] Since the screw rod 15 is threadedly sleeved with the screwing block 17, when the screwing block 17 rotates along the outer surface of the screw rod 15, it will move forward and backward at the same time. When the screwing block 17 moves backward, it will squeeze the front surface of the fixed plate 14, thereby blocking the rotation of the entire screw rod 15, and further fixing the entire screw rod 15. When the screwing block 17 moves forward, the fixing effect on the entire screw rod 15 will be released.

[0038] Wherein, a driving motor 18 is fixedly installed at the top end of the rotating plate 16, the other end of the output shaft of the driving motor 18 is fixedly sleeved with a rotating shaft 19, and the outer surface of the rotating shaft 19 is movably sleeved with the inside of the rotating plate 16.

[0039] When the driving motor 18 operates, the rotating shaft 19 will rotate at this time.

[0040] Wherein, a second rotating block 20 is fixedly sleeved at the bottom end of the rotating shaft 19, and the outer surface of the second rotating block 20 is movably connected with the outer surface of the first rotating block 13.

[0041] When the rotating shaft 19 rotates, it will drive the second rotating block 20 to rotate. Since the outer surface of the second rotating block 20 is movably connected with the outer surface of the first rotating block 13, when the second rotating block 20 rotates, it will drive the first rotating block 13 to rotate.

[0042] The working principle and usage process of the present utility model:

[0043] When an operator needs to change the overall orientation of the slewing reducer body 11, at this time, the operator holds the handle 9 and presses it downward. At this time, the handle 9 will drive the gear 4 to move downward through the round shaft 8. In this process, the gear 4 will compress the spring 7 through the round block 6. At the same time, the gear 4 will release the contact with the stop block 5 during the downward movement. At this time, the stop block 5 will not be able to block the rotation of the gear 4. Immediately afterwards, the operator shakes the handle 9. At this time, the handle 9 will drive the gear 4 to rotate through the round shaft 8. Since the outer surface of the gear 4 is meshed with the outer surface of the toothed ring 3, at this time, the gear 4 will drive the entire rotating block 2 to rotate through the toothed ring 3 during rotation, thereby realizing the function of adjusting the orientation angle of the slewing reducer body 11 according to the usage requirements. When the angle adjustment is completed, at this time, the operator releases the handle 9. Due to the elastic force of the spring 7, subsequently, the entire gear 4 will move upward under the drive of the spring 7 to reset. At this time, the outer surface of the gear 4 will contact the outer surface of the stop block 5 during the upward movement. At this time, the stop block 5 will block the rotation of the gear 4. At the same time, the gear 4 will block the rotation of the rotating block 2 through the toothed ring 3, so as to be able to fix the overall orientation angle of the slewing reducer body 11.

[0044] Subsequently, the operator turns the turning block 17. Since the inside of the turning block 17 is threadedly sleeved on the outer surface of the screw rod 15, when the turning block 17 rotates, it will move forward along the outer surface of the screw rod 15. At this time, the turning block 17 will release the extrusion on the front surface of the fixed plate 14 during the forward movement. At this time, the entire rotating plate 16 can rotate around the screw rod 15 as the axis, thereby realizing the function of adjusting the angle of the entire rotating plate 16, and further being able to prevent the driving motor 18 from blocking the objects installed on the slewing reducer body 11. When the turning block 17 moves backward along the outer surface of the screw rod 15, at this time, the turning block 17 will squeeze the front surface of the fixed plate 14. At this time, the turning block 17 will block the rotation of the entire rotating plate 16, thereby being able to fix the rotating plate 16.
