Device and method for measuring blade distance of a blade lock

Abstract

The invention provides a blade pitch measuring device and method of a blade lock, which relates to the technical field of measuring tools, including: a first measuring part, including: a first main body, a connecting block is arranged on both sides and a first connecting block is arranged on each connecting block A hole; the second hole is arranged at the bottom of the first body; the first through hole is located above the second hole; the second through hole is located above the first through hole and has a first through hole between the first through hole A horizontal interval; the first connecting rod is fixedly connected with the first main body, and a first L-shaped hook is provided on the top; the second measuring part includes: the second main body, a third through hole is opened near the bottom; the fourth through hole , located above the third through hole, and has a second transverse distance from the third through hole; the second connecting rod is arranged on the top of the second main body and fixedly connected with the second main body, and the top of the second connecting rod A second L-shaped hook is provided. There is no need to disassemble the lock core during the measurement process, the operation is simple, and there is no damage to the lock.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a device and method for measuring the distance between blades of a blade lock. Background technique [0002] The blade lock is a kind of lock. The modern blade side column lock uses the teeth with different angles on the key to withstand the blades in the aligned lock cylinder, so that the side column that originally blocked the lock sleeve falls into the lock cylinder, thereby realizing The lock cylinder rotates open. The blade lock is mainly composed of a lock sleeve, a lock cylinder, a blade, and a side column. The lock sleeve covers the lock cylinder, and there is a side column that can move up and down between the lock sleeve and the lock cylinder. When the key is not inserted, the side column is stuck between the lock sleeve and the lock cylinder, which limits the rotation of the lock cylinder. After the key is inserted, the curve on the key drives the blade to mo...

AI Technical Summary

Problems solved by technology

The existing measurement method needs to disassemble the lock, which has the following disadvantages: it is difficult to disassemble the lock; the blade lock is a compact workpiece. Although the lock is not big, it has more than 100 small parts, which are usually difficult to disassemble. Sometimes in order to get the data of some parts inside the lock, even use the wire cutting machine to cut the lock

It takes a lot of time to disassemble the lock; the disassembled lock is difficult to reinstall; because more than 100 small parts such as blades, springs, sheets, and snap rings are not easy to keep and easy to lose, and it is inconvenient to install them back into the lock, so in actual operation Usually disassembled locks are scrapped
