Manufacturing method of safety tension lock with protective function for rail transit

1. The present utility model relates to the technical field of safety tension locks, in particular to a safety tension lock with a protective function for rail transit.

Background technique:

2. In today's society, with the continuous development of the times, people's living standards have been greatly improved, and the emergence of rail transit has become an important means of transportation for people to travel.

There needs to be a lot of space in the body for the storage of items, and some spaces need to be protected by locks, and safety tension locks are widely used on trains in national highway traffic, but there are still many existing safety tension locks. problems and defects;

3. The traditional safety tension lock has the problem of poor protective effect during use, which leads to the phenomenon of rust and corrosion on the surface of the safety tension lock after long-term use, which makes the safety tension lock unable to be used flexibly.
