Embodiment Construction
[0031] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] figure 1 It is a schematic diagram of the overall structure of the tool of the present invention. The tool of the present invention comprises a main scale 1, a left auxiliary scale 2, a right auxiliary scale 5, a left limit assembly 3, a right limit assembly 6 and an origin positioning assembly 4, and all parts are preferably made of stainless steel through quenching treatment. The main ruler 1 is T-shaped, preferably a stainless steel plate, and formed by stamping. The length scale of the scale 12 is preferably processed by a laser marking process to ensure left-right symmetry, and the origin of the scale is at the center of symmetry.
[0033] The left auxiliary ruler 2 is preferably a stainless steel plate, which is formed by stamping, and then milled, drilled and tapped. The preferred known hand-tighteni...

The invention relates to a measuring tool for an anti-theft door lock cylinder, comprising a main ruler (1), a left auxiliary ruler (2), a right auxiliary ruler (5), a left limit assembly (3), a right limit assembly (6) and an origin The positioning component (4) belongs to the technical field of measurement and control. The invention can accurately measure the inner length and outer length of the anti-theft door lock cylinder without disassembling the anti-theft door lock cylinder, so that the locksmith does not need to disassemble and install the anti-theft door lock cylinder before ordering, which greatly simplifies the locksmith's replacement and upgrade of the lock Core business process, improve work efficiency. The tool of the present invention utilizes the tool tightening groove of the cross-shaped countersunk head screw for positioning the lock cylinder to determine the origin of measurement. The tool is accurate in positioning, easy to operate, and can meet business requirements. The invention adopts the structural design of the main ruler and the auxiliary ruler similar to a vernier caliper, and can acquire multiple length data not in the same plane as the measurement origin at one time, and can also be used for length measurement on similar occasions.
Description
[0001] 1. Technical field [0002] The invention relates to a lock cylinder measuring tool, which belongs to the technical field of measurement and control. [0003] 2. Background technology [0004] In order to reduce development costs, developers of newly built communities generally install A-level or B-level anti-theft locks with low security levels on the anti-theft doors. Therefore, when the owners move in, the police recommend upgrading to super-B-level or C-level lock cylinders; Many owners have to replace or upgrade the lock cylinder of the anti-theft door for reasons such as lost keys, lock failure, or being opened by outsiders. In this context, an industry of opening and changing locks was born. Those who specialize in this business are called locksmiths. [0005] At present, the process for locksmiths to replace or upgrade the lock cylinder is generally as follows: first dismantle the old lock cylinder, then measure the size of the lock cylinder with a vernier calip...
