Problems solved by technology
Some application scenarios also need to add wire channels inside the ball joint, which makes the existing joint connection structure relatively complicated, and needs to be locked with screws or even more other parts, which increases the production cost and is exposed on the surface of the connection structure The screws also affect the aesthetics of its appearance
In addition, the existing complex structure affects the assembly efficiency, and when the two connected parts move relative to each other, its internal structure is easily twisted together with the wires, causing the wires to wear and affect the service life

Embodiment Construction
[0023] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0024] For the convenience of description, the directions involved in the following are consistent with the directions of the drawings themselves, but do not limit the structure of the present invention.
[0025] Such as Figure 1 to Figure 8 As shown, a self-locking structure includes a first connecting piece 1, a second connecting piece 2 and a self-locking piece 3, the first connecting piece 1 and the self-locking piece 3 are relatively fixed, and the self-locking piece 3 and the second connecting piece 2 Relatively fixed, so that the first connecting part 1 and the second connecting part 2 are relatively fixed. In this embodiment, the self-locking structure is applied to the installation of the simulated doll as an example. In the illustration, the first connecting part 1 and the second connecting part 2 a...

The invention discloses a self-locking structure which comprises a first connector, a second connector and a self-locking part. A first connecting portion is formed on the first connector, a second connecting portion is formed on the second connector, and the first connecting portion cooperates with the second connecting portion. A first containing cavity is formed in the first connecting portion,a second containing cavity is formed in the second connecting portion, a first rotating shaft is formed on the first containing cavity, a second rotating shaft is formed on the second containing cavity, and the first rotating shaft is inserted to the second rotating shaft. The first connector is provided with a first channel, and a fixed portion inserted to the first channel is formed on the self-locking part. A through hole is formed in the self-locking part, and the second rotating shaft penetrates into the through hole. The peripheral edge of the through hole protrudes towards the first containing cavity to form a lock piece, a fixed groove is formed in the position, corresponding to the lock piece, of the second rotating shaft, and the lock piece is clamped and locked in the fixed groove. According to the self-locking structure, the self-locking part is arranged, the first connector and the second connector are oppositely fixed and do not need to be locked by a screw, the production cost is reduced, and the attractiveness degree of the appearance is improved; and the first connector and the second connector can oppositely rotate.
Description
technical field [0001] The invention relates to the field of mechanical installation, in particular to a self-locking structure. Background technique [0002] The ball joint is a commonly used connection structure, and its application fields are very wide, such as mechanical arms and artificial dolls, which can realize the relative rotation of the two connected parts, so as to imitate the movement effect of the real arm, so as to meet the corresponding movement requirements, such as The moving and fetching of the robotic arm, and the posing of the simulated doll. Some application scenarios also need to add wire channels inside the ball joint, which makes the existing joint connection structure relatively complicated, and needs to be locked with screws or even more other parts, which increases the production cost and is exposed on the surface of the connection structure The number of screws also affects the aesthetics of its appearance. In addition, the existing complex str...
