Abstract
The utility model relates to a bolt, nut not hard up inspection sign, constitute including two parts: an inner ring body portion made of an elastic material and an outer ring body portion made of an elastic material; the outer ring body part is detachably and matched and sleeved outside the inner ring body part to form a bolt and nut looseness check mark; the inner ring body part is a ring structure with a regular hexagon inside and a regular circular ring outside; the outer ring body part is a structure formed by splicing a regular hexagonal ring structure and a triangular structure. Bolt, nut not hard up inspection sign can make the inspection personnel through the light accurate connected state who observes bolt, nut of naked eye, only need just learn its not hard up condition through the visual observation, reduced bolt, nut and do not have the emergence of unnecessary artifical fastening situation under the not hard up condition to reduce the output of human cost and improved actual work efficiency. Bolt, nut not hard up inspection sign structure succinct, low cost, use extensively.
Description
Technical Field
The utility model belongs to machinery maintenance, car after sale and maintenance field relate to a bolt, nut not hard up inspection sign particularly.
Background
Bolts and nuts on machine equipment often loosen or deform under the action of external force. For example, due to the rotation of the wheel hub, the bumping of the vehicle, the load of the vehicle and the like, the hub bolt and the nut are always required to bear a large external force, the hub bolt and the nut are easy to loosen, and if the vehicle continues to run unconsciously under the condition, the risk of tire falling can be caused, and great loss is caused to traffic safety and property. Operators of mechanical equipment such as automobile hubs and the like cannot timely observe with naked eyes whether bolts and nuts are loosened, so that the problem of tightness of connection of the bolts and the nuts can be solved only by manual regular timing inspection. The manual inspection method is low in efficiency, time-consuming and labor-consuming, and in the inspection process, the bolt and the nut are often applied with tightening force, and the bolt and the nut can be elongated, deformed and even broken after the bolt and the nut are taken down for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an effectual not hard up inspection problem of having solved fastening bolt, nut provides a bolt, the not hard up inspection sign of nut, can be surveyed whether bolt, nut are not hard up, reduce the human cost, improve work efficiency.
In order to solve the technical problem, the purpose of the utility model is realized through following technical scheme:
bolt, nut looseness inspection sign includes two parts: an inner ring body portion made of an elastic material and an outer ring body portion made of an elastic material;
the outer ring body part is detachably and closely sleeved outside the inner ring body part in a matched manner to form a bolt and nut looseness check mark;
the inner ring body part is of a ring structure with a regular hexagon inside and a regular circular ring outside; the outer ring body part is a structure formed by splicing a regular hexagonal ring structure and a triangular structure.
The size of the inner ring body part is the same as that of the hexagonal bolt and the nut to be checked, and the inner ring body part is tightly sleeved on the bolt and the nut, so that the original hexagonal appearance of the bolt and the nut is changed into the circular appearance.
The outer ring body portion is rotatable 360 degrees and can maintain an outer shape at all times.
Tightly sleeving the inner ring body part outside the bolt and the nut to be checked, and tightly sleeving the outer ring body part outside the inner ring body part; installing the bolt and nut looseness check marks on adjacent bolts and nuts by the same method; the outer ring body part is rotated to enable the triangular outer corners of two adjacent bolts and nut looseness check marks to be opposite directions; when the bolt and the nut are loosened, the pointed positions of the outer corners of the triangle change, so that the function of checking the looseness of the bolt and the nut is realized.
The beneficial effects of the utility model reside in that:
bolt, nut not hard up inspection sign can make the inspection personnel through the light accurate connected state who observes bolt, nut of naked eye, only need just learn its not hard up condition through the visual observation, reduced bolt, nut and do not have the emergence of unnecessary artifical fastening situation under the not hard up condition to reduce the output of human cost and improved actual work efficiency. Bolt, nut not hard up inspection sign structure succinct, low cost, use extensively.

Detailed Description
The present invention will be described in further detail below: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-3, the bolt and nut looseness inspection mark comprises two parts: an inner ring body part 1 made of an elastic material and an outer ring body part 2 made of an elastic material;
the outer ring body part 2 is detachably and closely sleeved outside the inner ring body part 1 in a matched manner to form a bolt and nut looseness check mark;
the inner ring body part 1 is an annular structure with a regular hexagon inside and a regular circular ring outside; the outer ring body part 2 is a structure formed by splicing a regular hexagonal ring structure and a triangular structure.
The size of the inner ring body part 1 is the same as that of a hexagonal bolt and a nut to be checked, and the inner ring body part 1 is sleeved on the bolt and the nut, so that the original hexagonal appearance of the bolt and the nut is changed into a circular ring appearance.
The outer ring body part 2 can be rotated 360 degrees and can always maintain the outer shape.
The outer ring body part 2 is rotated to enable the triangular outer corners of two adjacent bolts and nuts loosening inspection marks to be opposite directions, and when the bolts and the nuts are loosened, the positions pointed by the triangular outer corners are changed, so that the function of inspecting the loosening of the bolts and the nuts is realized.
The above description is only the preferred embodiments of the present invention, and these embodiments are all based on the present invention, and the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
