[0038] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The terms such as "upper", "lower", "left", "right", and "middle" used in this specification are only for the convenience of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of the present invention without substantially changing the technical content.

[0040] like Figures 1 to 3As shown, the embodiment of the utility model provides an adaptive bending flexible structure and a wire feeding device including the adaptive bending flexible structure, wherein the adaptive bending flexible structure includes a positioning base 1, an elastic arc plate 2, a load-bearing assembly seat 3 and a transmission convex seat 4, which is used to use the positioning base 1 as the positioning basis of the overall structure, and use the load-bearing assembly seat 3 as the load application basis, so that the elastic arc plate 2 can adaptively produce elastic deformation, and can automatically deform and recover after the load is unloaded, thereby forming a reciprocating bending flexible structure for a specific assembly scenario. The specific settings are as follows:

[0041] Please refer to Figure 1 and Figure 2 The positioning base 1 is configured as a plate seat structure with assembly holes, so as to effectively serve as a structural positioning basis for one end portion of the elastic arc plate 2 through the positioning base 1 .

[0042] One end of the elastic arc plate 2 is integrally formed and fixedly connected to the top surface of the positioning base 1, and the other end of the elastic arc plate 2 is integrally formed and fixedly connected to the load-bearing assembly seat 3; the curved inner side of the elastic arc plate 2 faces away from the positioning base 1, and the curved inner side of the elastic arc plate 2 faces the load-bearing assembly seat 3, so that the stress of the elastic arc plate 2 during the deformation process is more concentrated, thereby significantly improving the bending resistance and fatigue life of the elastic arc plate 2.

[0043] The transmission boss 4 is fixedly arranged at a side position of the top end of the load-bearing assembly seat 3, so that when a load is applied to the load-bearing assembly seat 3, the load-bearing assembly seat 3 adaptively shifts based on the flexible deformation of the elastic arc plate 2, and can then be synchronously transmitted to the external detection element via the transmission boss 4.

[0044] Please refer to Figure 3 The wire feeding device further comprises a wire feeding base 5, a fixed wheel body 6, a swing wheel body 7 and a micro switch 8; wherein:

[0045] The fixed wheel body 6 is installed at the top of the wire feeding base 5 in a fixed axis transfer assembly.

[0046] The positioning base 1 is fixedly assembled at the top position of the wire feeding base 5 , and the positioning base 1 and the load-bearing assembly seat 3 are correspondingly located at one side of the fixed wheel body 6 .

[0047] The load-bearing assembly seat 3 is provided with a swing wheel groove 31 , the opening position of the swing wheel groove 31 at least corresponds to one side of the load-bearing assembly seat 3 close to the fixed wheel body 6 , and the load-bearing assembly seat 3 is provided with swing wheel shaft holes 32 on both side inner walls corresponding to the swing wheel groove 31 .

[0048] The swing wheel body 7 is correspondingly arranged inside the swing wheel groove 31, and the wheel axle adapter of the swing wheel body 7 is arranged on the swing wheel axle hole 32 of the inner wall on both sides of the swing wheel groove 31. In the initial state, the fixed wheel body 6 and the swing wheel body 7 are in contact and pressed. When the wire a passes through the middle of the two wheels, the swing wheel body 7 swings toward the side away from the fixed wheel body 6. In the switching process between the two states of wire and wire, the diameter change process of the wire a makes the structure swing adaptively and flexibly.

[0049] The micro switch 8 is fixedly assembled on the positioning base 1, and in the initial state, the micro switch 8 and the transmission boss 4 are separated from each other. When the swing wheel body 7 swings, the micro switch 8 and the transmission boss 4 are in contact with each other, so as to realize that when the wire a passes through, the trigger state of the micro switch 8 is used to effectively complete the detection of the position state of the wire a.

[0050] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
