Description

Technical Field

[0001] The utility model relates to the field of positioning mechanisms, in particular to an annular inner ring clamping type positioning structure. Background Art

[0002] At present, rotary positioning mechanisms are widely used in many fields such as machinery, electronics, and automobiles. Traditional rotary positioning mechanisms mostly rely on glass beads, springs and other components for limiting and fixing. Although this design meets the functional requirements to a certain extent, it also brings a series of problems.

[0003] First, using glass beads, springs and other components for positioning means that more parts are needed to cooperate. These parts need to be precisely aligned and fixed during installation, which not only increases the complexity and time cost of installation, but also increases the skill requirements of the installer. At the same time, the cooperation between multiple parts is prone to deviation or looseness, resulting in unstable positioning accuracy and affecting overall performance.

[0004] Secondly, the coordination of multiple parts also leads to rising costs. Each part needs to go through multiple links such as manufacturing, processing, and inspection, all of which will increase manufacturing costs. In addition, as the number of parts increases, the difficulty of management and maintenance will also increase accordingly, further increasing the cost burden.

[0005] Therefore, it is necessary to provide an annular inner ring clamping type positioning structure to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an annular inner ring clamping type positioning structure.

[0007] The utility model provides an annular inner ring clamping type positioning structure, including a seat body, a circular connecting portion is provided on the top of the seat body, a mounting groove is provided in the circular connecting portion, a spring sheet structure is installed in the mounting groove, the outer wall of the spring sheet structure is in contact with the inner wall of the mounting groove, the spring sheet structure includes a connecting portion and a first positioning portion bent inwardly, a first deformation portion bent outwardly, a pressure-bent portion bent outwardly, a second deformation portion bent outwardly and a second positioning portion bent inwardly, which are sequentially arranged at the end of the connecting portion, the first positioning portion and the second positioning portion are symmetrically arranged, the first deformation portion and the second deformation portion are symmetrically arranged, a rotating part is rotatably connected to the outer side of the circular connecting portion, and the inner wall of the rotating part is provided with a positioning groove matching the pressure-bearing portion.

[0008] Preferably, the middle portion of the mounting groove is a circular portion, and the connecting portion is arranged in the circular portion.

[0009] Preferably, the top of the mounting groove is provided with a rounded corner.

[0010] Preferably, the depth of the mounting groove is greater than the thickness of the circular connecting portion.

[0011] Preferably, the outer side wall of the rotating member is flush with the outer side wall of the seat body.

[0012] Compared with the related art, the utility model has the following beneficial effects:

[0013] The first positioning portion and the second positioning portion are symmetrically arranged, and the first deformation portion and the second deformation portion are symmetrically arranged. The middle part of the installation slot is a circular portion, and the connecting portion is arranged in the circular portion. The spring structure can be installed by rotating 180 degrees along the Z axis, or by rotating 180 degrees along the X axis, or by rotating 180 degrees along the X axis. The spring structure will not be installed incorrectly when installed in the installation slot. The spring structure is formed by bending a steel sheet and is arranged in an integrated manner. It is relatively simple to manufacture, convenient for maintenance, and convenient for installation of the spring structure, reducing time costs. In addition, the structure is relatively stable and has relatively high precision.

[0014] By the connection part and the first positioning part, the first deformation part, the pressure part, the second deformation part and the second positioning part arranged at both ends of the connection part, the two symmetrically arranged pressure parts cooperate with the corresponding positioning grooves, so that the snap-fit ​​positioning cooperation between the seat body and the rotating part is more stable.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figures 1 to 3, an annular inner ring snap-fit ​​positioning structure, comprising a seat body 1, a circular connecting portion 2 is provided on the top of the seat body 1, a mounting groove 3 is provided in the circular connecting portion 2, a spring structure 4 is installed in the mounting groove 3, the outer wall of the spring structure 4 is in contact with the inner wall of the mounting groove 3, the spring structure 4 comprises a connecting portion 41 and a first positioning portion 42 bent inwardly, a first deformation portion 43 bent outwardly, a pressure portion 44 bent outwardly, a second deformation portion 45 bent outwardly and a second positioning portion 46 bent inwardly, which are sequentially arranged at the end of the connecting portion 41, the first positioning portion 42 and the second positioning portion 46 are symmetrically arranged, the first deformation portion 43 and the second deformation portion 45 are symmetrically arranged, the outer side of the circular connecting portion 2 is rotatably connected to a rotating member 5, and the inner wall of the rotating member 5 is provided with a positioning groove 6 matched with the pressure portion 44.

[0021] The middle part of the installation slot 3 is a circular part 31, and the connecting part 41 is arranged in the circular part 31. The spring structure 4 can be installed by rotating 180 degrees along the Z axis, or by rotating 180 degrees along the X axis, or by rotating 180 degrees along the X axis. The spring structure 4 can be installed in the installation slot 3 without error. The top of the installation slot 3 is provided with a rounded corner 32, which is convenient for installing the spring structure 4 in the installation slot 3.

[0022] The rotating member 5 is rotated, and the inner wall of the rotating member 5 squeezes the pressed portion 44, so that the first deformation portion 43 and the second deformation portion 45 are deformed, and the pressed portion 44 shrinks into the mounting groove 3. Since the first positioning portion 42, the second positioning portion 46 and the connecting portion 41 are protected by the side walls of the mounting groove 3, no deformation will occur. When the pressed portion 44 is rotated to face the positioning groove 6, the pressed portion 44 is separated from the squeezing of the inner wall of the rotating member 5, and the pressed portion 44 is restored and re-engaged in the positioning groove 6, thereby forming the positioning and fixation of the rotating member 5 and the seat body 1.

[0023] The depth of the installation groove 3 is greater than the thickness of the circular connecting portion 2 , so that the installation of the spring structure 4 to the installation groove 3 is more stable.

[0024] The outer wall of the rotating member 5 is flush with the outer wall of the seat body 1, making the whole more beautiful.
