Description

Technical Field

[0001] This utility model relates to a self-locking rotary structure based on elastic deformation. Background Technology

[0002] Disadvantages of existing solutions: 1. Complex structure with a large number of parts Existing rotating structures typically consist of multiple components, including independent elastic elements (such as springs), fixed parts, and rotating parts, which increases the complexity of manufacturing and assembly and requires higher production costs.

[0003] 2. Inconvenient to operate Some existing structures require complex operating procedures (such as manual locking or unlocking) when rotating or fixing, resulting in a poor user experience, especially in scenarios where frequent angle adjustments are required.

[0004] 3. Insufficient reliability Complex structures are more likely to develop problems such as loosening, gear failure, or uneven rotation after long-term use. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a technical solution for a self-locking rotary structure based on elastic deformation.

[0006] The self-locking rotary structure based on elastic deformation is characterized by comprising a base and a chuck. The base is provided with a gear slot and an assembly notch, and a recessed elastic part is provided at the center of the base. The elastic part can provide axial preload through its own deformation. The chuck is provided with a buckle that cooperates with the assembly notch, and the shape of the buckle matches the shape of the gear slot. The buckle of the chuck is inserted into the base through the assembly notch. When the chuck is rotated, the buckle of the chuck engages and limits the gear slot. The elastic part at the center of the base presses the chuck with the axial preload generated by its own deformation, realizing multi-gear suspension. When disassembling, pressing down on the chuck will disengage the buckle from the gear slot. Adjusting the chuck in the opposite or forward direction will allow the buckle to rotate to the assembly notch and disengage.

[0007] The self-locking rotary structure based on elastic deformation is characterized in that an annular limiting part is provided above the base, the inner circle of the annular limiting part is provided with a protruding inner edge, symmetrical assembly notches are provided on the circumference of the inner edge, and multiple sets of stop grooves are provided below the inner edge; the elastic part is located at the center of the base, and the elastic part includes an outer support part and an inner support part. The outer support part is connected to the base through an outer ring connecting part, and the inner support part is connected to the outer support part through an inner ring connecting part. A guide post is provided at the center of the inner support part, and the guide post faces the side of the mounting chuck.

[0008] The self-locking rotary structure based on elastic deformation is characterized in that the chuck includes a rotating part and an outer connecting part, a pair of protruding buckles are provided around the circumference of the rotating part, a guide hole is provided at the center of the rotating part, and a reinforcing rib is provided between the guide hole and the rotating part.

[0009] The self-locking rotating structure based on elastic deformation is characterized in that the diameter of the rotating part is smaller than the diameter of the inner edge of the annular limiting part of the base.

[0010] The self-locking rotary structure based on elastic deformation is characterized in that the upper surface of the buckle is configured as a structure with a low middle and high ends, and the stop groove is a structure with multiple sets matching the shape of the buckle.

[0011] The self-locking rotary structure based on elastic deformation is characterized in that the groove depth of the gear slot is 0.5-1.5mm.

[0012] The self-locking rotary structure based on elastic deformation is characterized in that the outer connecting part of the chuck is connected to an external object.

[0013] This utility model utilizes a chuck and base, eliminating the need for additional parts assembly and complex button unlocking. The chuck can be easily twisted for convenient removal, resulting in a more ergonomic design. With only two components and no complex structure, reliability is higher and maintenance is easier. Manufacturing and assembly complexity are reduced, while still enabling hovering and gear shifting. No additional elastic elements are required; elasticity is provided by the structural deformation of the base's elastic section, simplifying the design. The buckle engages with the gear shift slot, enabling rotation and adjustable gear shifting to meet multi-angle hovering requirements. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings: A self-locking rotary structure based on elastic deformation includes a base 1 and a chuck 2. The base 1 is provided with a gear slot 5 and an assembly notch 4. A recessed elastic part is provided in the center of the base 1, which can provide axial preload through its own deformation. The chuck 2 is provided with a buckle 13 that cooperates with the assembly notch. The shape of the buckle 13 matches the shape of the gear slot 5. The buckle 13 of the chuck 2 is inserted into the base 1 through the assembly notch 4. When the chuck 2 is rotated, the buckle 13 of the chuck engages and limits the gear slot 5. The axial preload generated by the deformation of the elastic part in the center of the base 1 presses against the chuck 2, which can realize multi-gear suspension. When disassembling, pressing down on the chuck 2 will disengage the buckle 13 from the gear slot 5. Adjusting the chuck 2 in the reverse or forward direction will allow the buckle to rotate to the assembly notch and disengage.

[0016] The specific structure is as follows: An annular limiting part 3 is provided above the base 1. The inner circle of the annular limiting part 3 is provided with a protruding inner edge 301. Symmetrical assembly notches 4 are provided on the circumference of the inner edge 301. Multiple sets of gear slots 5 are provided below the inner edge 301. The elastic part is located at the center of the base 1. The elastic part includes an outer support part 6 and an inner support part 8. The outer support part 6 is connected to the base through an outer ring connecting part 7. The inner support part 8 is connected to the outer support part 6 through an inner ring connecting part 9. A guide post 10 is provided at the center of the inner support part 8. The guide post 10 faces the side where the chuck is installed.

[0017] The chuck 2 includes a rotating part 11 and an external connecting part 12. The rotating part 11 has a pair of protruding buckles 13 around its circumference. The rotating part 11 has a guide hole 15 at its center that cooperates with the guide post 10. A reinforcing rib 14 is provided between the guide hole 15 and the rotating part. The external connecting part 12 of the chuck 2 is connected to an external attachment 16, which can be a mobile terminal, etc.

[0018] For ease of installation, the diameter of the rotating part 11 is slightly smaller than the diameter of the inner edge of the annular limiting part of the base.

[0019] The upper surface of the buckle 13 can be set to a structure that is low in the middle and high at both ends, with a slope angle of 30-45 degrees; the stop groove 5 is a set of structures that match the shape of the buckle, and the groove depth is 0.5-1.5mm.

[0020] This utility model utilizes a chuck and base, eliminating the need for additional parts assembly and complex button unlocking. The chuck can be easily twisted for convenient removal, resulting in a more ergonomic design. With only two components and no complex structure, reliability is higher and maintenance is easier. Manufacturing and assembly complexity are reduced, while still enabling hovering and gear shifting. No additional elastic elements are required; elasticity is provided by the structural deformation of the base's elastic section, simplifying the design. The buckle engages with the gear shift slot, enabling rotation and adjustable gear shifting to meet multi-angle hovering requirements.
