Description

Technical Field

[0001] The utility model relates to the technical field of rotation positioning, in particular to a precision locking structure based on an underwater motion rotation positioning mechanism. Background Art

[0002] The underwater motion-based rotation positioning mechanism is a device used for underwater operations, which can achieve 360-degree continuous rotation and can detect the rotation angle and angular acceleration.

[0003] Publication number CN114654413A describes a vertical positioning and rotation mechanism. A knob plunger is fixed to the upper cover and can be positioned on the base via a pin. During positioning, the knob plunger is released and the pin retracts, causing the upper cover and base to rotate relative to each other around an axis until the corresponding limit strut for the product is in the set position. The knob plunger is then reset so that the lower end of the pin extends downward into the corresponding pin hole, prohibiting relative rotation of the upper cover and base around the axis. This vertical positioning and rotation mechanism features a set number and height of limit struts tailored to the product. Manual rotation, combined with different height limit struts, allows for the desired vertical positioning heights of different products. The mechanism boasts a simple structure, low cost, and ease of operation.

[0004] As shown in the above-mentioned equipment, the rotary positioning mechanism of the prior art can achieve different vertical positioning height requirements of different products, has a simple structure, low cost, and is easy to operate. However, in the absence of a locking structure, when the equipment operates in an underwater environment, the influence of the water flow may cause displacement or deformation of the overall structure, thereby affecting the accuracy and stability of the positioning of its turntable. In addition, the existing rotary positioning mechanisms are mostly complex fixed installations, and it takes a lot of time to maintain and replace the equipment, resulting in excessive downtime.

[0026] See Figure 1-Figure 5, the utility model provides the following two technical solutions:

[0032] A positioning hole 8 is formed on the outer wall of the rotary disk 5 , and the rotary disk 5 is positioned by inserting a positioning sleeve 38 into the positioning hole 8 .

[0033] The locking connection mechanism 6 includes a connecting plate 61, the outer wall of which is provided with a screw hole 62. The connecting plate 61 is connected to the bottom end of the connecting seat 1 by bolts. The outer wall of the connecting plate 61 is fixedly provided with a mounting seat 63, and the other end of the mounting seat 63 is provided with a locking connection component 64.

[0034] The locking connection assembly 64 includes a tube 641, which is fixedly mounted on the outer wall of the mounting seat 63, one end of the tube 641 is fixedly connected to a connecting sleeve 642, the inner wall of the tube 641 is fixedly connected to a limiting tube 644, the outer wall of the limiting tube 644 is provided with a reset spring A645, one end of the reset spring A645 is fixedly connected to a sliding ring 646, the inner wall of the limiting tube 644 is provided with a limiting plate 648, the outer wall of the connecting sleeve 642 is slidably connected to a pushing ring 643, the inner wall of the pushing ring 643 is fixedly connected to a movable block, one end of the movable block is fixedly connected to a reset spring B647, the inner wall of the connecting sleeve 642 is provided with a limiting groove 649, and the internal movably connection of the limiting valve ball 6410 is provided in the limiting groove 649.

[0035] The precision locking structure based on the underwater motion rotary positioning mechanism is provided with a locking connection mechanism 6, which can ensure the stability of the underwater motion rotary positioning mechanism during operation and prevent the structure from loosening or displacement due to external factors such as water flow and water pressure. At the same time, the locking connection component 64 can be used to quickly disassemble and assemble the equipment at a certain point, which can significantly shorten the time required for maintenance, reduce equipment downtime, and improve overall work efficiency.

[0036] The second embodiment is mainly different from the first embodiment in that: the auxiliary positioning component 3 includes a connecting box 32, the connecting box 32 is fixedly installed on the top of the connecting seat 1, the top of the connecting box 32 is fixedly installed with a limiting support column 31, the inner wall of the connecting box 32 is fixedly installed with a threaded sleeve 33, the bottom end of the threaded sleeve 33 is rotatably connected to a worm gear 34, the outer wall of the worm gear 34 is engaged with a worm 36, the worm 36 is rotatably connected to the inner wall of the connecting box 32, one end of the worm 36 is fixedly connected to a driving rod 37, the top of the worm gear 34 is fixedly connected to a threaded rod 35, the outer wall of the threaded rod 35 is threadedly connected to a positioning sleeve 38, and the positioning sleeve 38 is slidably connected to the outer wall of the limiting support column 31.

[0037] The precision locking structure based on the underwater motion rotary positioning mechanism is provided with an auxiliary positioning component 3, which can help the turntable 5 to be positioned more accurately in the underwater environment, reduce positioning errors caused by factors such as water flow and water pressure, thereby improving the accuracy and reliability of the operation.

[0038] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0039] When the device as a whole needs to be locked and connected, the push ring 643 can be pushed first to drive the movable block to move and squeeze the return spring B647. As the push ring 643 gradually moves out of the range of the limit groove 649, the limit valve ball 6410 is in an active state. At this time, the return spring A645 is used to reset and drive the sliding ring 646 connected to one end to move, so that the locking connection mechanism 6 can be inserted into the fixed point installation column as a whole. Then, as the installation column gradually enters the locking connection mechanism 6, the sliding ring 646 and the return spring A645 will be squeezed. When it enters to a certain extent, the push ring 643 is released. As the return spring B647 moves, the push ring 643 can be driven to reset and cover the limit groove 649. At the same time, the limit valve ball 6410 is squeezed to move inward and get stuck in the slot opened on the outer wall of the installation column. In this way, the locking connection mechanism 6 can be fixed and installed on the fixed point as a whole. The mounting column of the point is mounted on the mounting column to complete the locking installation of the locking connection mechanism 6, and then the connection with the connecting seat 1 is completed through the connecting disk 61 and with the help of bolts, thereby completing the installation of the entire equipment. The locking connection mechanism can ensure the stability of the entire equipment during operation during underwater movement to reduce the impact of external factors such as water flow and water pressure. When the turntable 5 needs to be positioned, the driving assembly 4 is used to drive the driving rod 37 and the worm 36 to rotate, and the rotation of the worm 36 drives the worm wheel 34 to rotate, and the rotation of the worm wheel 34 drives the threaded rod 35 connected to the inner wall of the threaded sleeve 33 to rotate, and the threaded rod 35 is rotated and the positioning sleeve 38 is limited by the limiting support column 31 through the threaded rod 35, driving the positioning sleeve 38 to gradually move upward. As the positioning sleeve 38 gradually moves upward and passes through the positioning hole 8, the turntable 5 can be limited and positioned.
