Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions.

In the description of the present invention, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and that the directional terms are used for purposes of illustration only and are not to be construed as limiting, for example, "upper" and "lower" are not necessarily limited to directions opposite or coincident with the direction of gravity. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1, a crimping structure includes a base 1 and a positioning member 2, which form a positioning structure. The base 1 comprises a base body 12, the surface of the base body 12 is recessed towards the inside of the base body 12 to form a V-shaped groove 11, and the V-shaped groove 11 has two side surfaces 111 arranged in a V shape. The upper surface of the base 12 is shown in fig. 1 as being depressed downward to form the V-shaped groove 11 described above.

Two positioning parts 2 are arranged at intervals along the length direction of the V-shaped groove 11. In the present embodiment, two positioning members 2 are provided at both ends of the V-shaped groove 11 in the longitudinal direction, respectively. Each positioning element 2 comprises two positioning branches 21 arranged in a V-shape, each positioning branch 21 being made on a side 111 of the V-groove 11 in abutment with the corresponding side 111. The two positioning branches 21 can be joined at the tip of the V, while preferably the two positioning branches 21 are of integral construction. The space between the two positioning branches 21 is used to hold a rod-shaped crimping object 100. In the present embodiment, each positioning subsection 21 is a cylinder having a circular cross-section.

Preferably, the angle of the V-shaped groove 11 is identical to the angle of the positioning member 2, as shown in fig. 2. Alternatively, the included angle of the positioning component 2 may also be larger than the included angle of the V-shaped groove 11, so that the positioning component 2 is inclined relative to the V-shaped groove 11, that is, the two positioning branches 21 of the same positioning component 2 are respectively attached to two asymmetric positions of the two side surfaces 111, where the asymmetry refers to that the two positioning branches are not located on the same vertical cross section when placed in the direction shown in fig. 2.

The two positioning elements 2 form a substantially uniform angle and preferably the two positioning elements 2 are arranged parallel to each other. The longer the distance between the two positioning members 2, the more stable the crimping structure. Even if the included angles of the two positioning members 2 are not consistent, only the initial crimping position is affected, and the repeated positioning accuracy is not affected.

The crimping structure further includes a crimping piece 3 that presses the crimping object 100 against the positioning member 2.

Referring to fig. 2, in use, after a bar-shaped compression object 100 (the length direction of which coincides with the length direction of the V-shaped groove 11) is placed in the V-shaped groove 11, the compression object 100 is pressed against the positioning member 2 by the compression member 3, whereby the compression object 100 can be pressed to the lowest stable position of the V-shaped groove 11. Wherein the direction of the applied force of the crimp member 3 is shown by an arrow in fig. 2. In this four-point positioning manner (each positioning part 21 corresponds to one positioning point), after the initial adjustment, the directions of placing the compression-bonded object 100 each time are all the same, and the repeated adjustment and positioning are not required.

Referring to fig. 3-1, the cross-section of the positioning section 21 may also be in the shape of a meniscus, where the flat surface 211 of the meniscus is attached to the side 111 of the V-groove 11, and the curved surfaces 212 of the two menisci form a V-shaped structure for positioning the compression-bonded object 100.

Referring to fig. 3-2 and 3-3, the cross-section of the positioning section 21 may also be semicircular, triangular or blade-shaped (triangle with very small apex angle).

Alternatively, the positioning member 2 may be formed not in a column structure forming a V shape but in a side surface 111 of the V-shaped groove 11 using two balls or hemispheres as the positioning branches 21.

Referring to fig. 4 to 6, for the application examples of the crimping structure of the present invention, which are respectively an arc pendulum turntable, a mirror bracket and an adjusting bracket, the crimping structure is used as a bearing, the crimping object 100 constitutes a rotating shaft, the base 1 is one of these devices, and the crimping piece 3 is composed of corresponding parts of these devices which rotate relative to the "base 1", so that a device with high precision and high stability can be obtained.
