Description

Technical Field

[0001] The utility model relates to the technical field of positioning pins, in particular to a high-precision safety airbag positioning pin. Background Art

[0002] A locating pin is a part used to limit the freedom of an object. It is mainly used in mechanical motion equipment, especially in determining the position in two-dimensional space. It is usually used for assembly positioning, and can also be used as an overload shear connection in connection, relaxation or safety devices. The basic forms of locating pins include cylindrical pins and conical pins, among which the circular locating pin is the basic positioning element connector in the design of machine tool fixtures. The implementation principle of the locating pin involves the matching of geometric shapes, the fitting of surfaces, and the application of fastening methods. These principles together ensure that the locating pin can accurately locate and fix the connectors, thereby maintaining the relative position between them. When using locating pins for positioning, some basic principles should be followed, such as giving priority to locating pins with high precision, and properly adjusting or grinding the pressure block or locating pin under specific conditions to ensure the precise position relationship between the workpieces. In addition, the standard size specification table of locating pins provides specific size information of locating pins of different models and specifications, which is crucial for selecting suitable locating pins. For example, the 304 stainless steel pin shaft M5 flat head cylindrical pin with hole is a common locating pin specification. In the aviation field, locating pins also have special applications, such as aviation locating pin through-core clamps, which are used to ensure the positioning of components under high precision requirements.

[0003] The application number is CN202221624701.9, which discloses a positioning pin. The positioning pin comprises: a sleeve, comprising a wall portion, a through hole formed by the wall portion and penetrating along a first direction, and a locking groove arranged on the wall portion and communicating with the through hole; a push rod member arranged in the through hole, comprising a locking portion, and a receiving groove arranged on the locking portion; a locking member arranged between the locking groove and the locking portion of the sleeve, wherein the push rod member is movably arranged in the through hole along the first direction so that the locking portion can be movably arranged between a locking position and an unlocking position, in the unlocking position, the locking groove is communicated with the receiving groove, the locking member is located in the locking groove and the receiving groove, in the locking position, the locking groove and the receiving groove are misaligned, the locking member is located between the locking groove and the outer surface of the locking portion, and at least part of the locking member extends out of the locking groove and protrudes from the outer surface of the sleeve. The positioning pin provided in the embodiment of the present application can position the assembly hole, and can be simply and conveniently removed from the assembly hole after the assembly hole is positioned.

[0004] Although the above-mentioned utility model can position the assembly hole through the wall portion, the through hole formed by the wall portion and penetrating along the first direction, and the locking groove arranged on the wall portion and connected with the through hole, and can be simply and conveniently removed from the assembly hole after the assembly hole is positioned, there is a shortcoming that when the device is tested, it is not suitable for different rugged road conditions and some types of roadblocks. This will make the tested data subsidize all scenarios in daily use.

[0005] Therefore, it is necessary to install a lubrication component in the middle of the device so that when the device is used, the internal lubricating oil can be squeezed out during exercise and lubrication can be performed to avoid rust caused by long-term use, which further causes noise.
