Abstract
The utility model relates to a structure whether inspection rivet takes place to become flexible, including rivet, connecting piece, the rivet on request with connecting piece riveting together, the rivet head on be provided with the mark line, the mark line run through the rivet and extend to on the terminal surface of connecting piece. The utility model discloses a whether the observation mark line determines the rivet and takes place to become flexible to can be to rivet place under repair or the change that takes place to become flexible, guaranteed the security and the reliability of mechanical device operation.
Description
Technical field
This utility model relates to a kind of structure checking whether rivet loosens, in order to judge that rivet is in use
No generation loosens.
Background technology
Riveting is a kind of conventional mechanical connecting device, and manufactured head is generally cup head or socket cap, is riveted on use process
In, due to reasons such as mechanical vibration, it is possible to can loosen, there is the safety that machinery will be used by the rivet loosened
Adverse effect is brought with reliability.Therefore, quickly judge whether rivet loosens, for machinery operational reliability and
Safety is the most necessary.
Summary of the invention
The purpose of this utility model is that providing a kind of can quickly check the knot the most whether rivet loosens
Structure.
The purpose of this utility model is achieved through the following technical solutions:
Check that the structure whether rivet loosens includes that connector is riveted together by rivet, connector, described rivet on request,
Being provided with mark line in described rivet head, described mark line runs through rivet and extends on the end face of connector.Described
The protection of polyurethanes varnish is scribbled on mark line.
By observing mark line, this utility model, when machinery runs, judges whether rivet loosens, if riveting
Nail occurs to loosen, then rivet head mark line can occur relative movement with the mark line on connector surface, and attendant only needs to check
Whether mark line misplaces and i.e. can determine whether whether rivet loosens, and places under repair to there is the rivet loosened or changes, it is ensured that machinery dress
Put the safety and reliability of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
As it can be seen, check that the structure whether rivet loosens includes rivet 1, connector 2, described rivet 1 is by wanting
Asking and be riveted together by connector 2, described rivet 1 head is provided with mark line 3, described mark line 3 runs through rivet
1 and extend on the end face of connector 2.The protection of polyurethanes varnish is scribbled on described mark line 3.
Claims (2)
1. the structure checking whether rivet loosens, it is characterised in that described structure includes rivet (1), connector
(2), connector (2) is riveted together by described rivet (1) on request, and described rivet (1) head is arranged
Mark line (3), described mark line (3) is had to run through rivet (1) and extend on the end face of connector (2).
A kind of structure checking whether rivet loosens the most as claimed in claim 1, it is characterised in that described mark line
(3) protection of polyurethanes varnish is scribbled on.
