Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, and more specifically to a bolster spring assembly height ruler. Background Art

[0002] The bolster spring is an important component of the railway vehicle bogie. It is a spring component that supports the bogie bolster to bear the load of the molten iron car. During installation, the installation height needs to be continuously measured so that the operator can easily assemble the spring. Therefore, a height gauge is needed. The height gauge is also called a height vernier caliper. When the existing height gauge is not in working state, the main scale is in a higher position and occupies the height space of the differential fine-tuning height gauge, resulting in the existing height gauge being difficult to store due to the large space occupied.

[0003] After searching, a Chinese patent with publication number CN219433953U discloses a height gauge in the field of measuring rulers. The structure can limit and fix the main ruler through a fixed pin and a rotating shaft to ensure that the main ruler and the base are in a vertical state, and measure the object through the measuring claws, the vernier and the main ruler. When the height gauge needs to be stored, the main ruler can be rotated along the fixed pin after the rotating shaft is separated from the limiting groove. At the same time, the main ruler is tilted relative to the base, and part of the main ruler body can be embedded in the limiting groove, thereby reducing the overall height and avoiding the main ruler occupying the height space of the height gauge, reducing the occupied space of the height gauge, and making it easier to store the height gauge.

[0004] However, in actual use, since the size of the main ruler of the base set by this structure is fixed and the size of the limit groove is also fixed, and since the size of the main ruler is larger than the size of the base, when the main ruler is stored, one end of the main ruler will exceed the range of the base. Therefore, when the base and the main ruler need to be moved, they will be affected by external factors, causing the main ruler that exceeds the range of the base to be bumped, thereby affecting the service life of the main ruler.
