Description
Technical field
The invention belongs to unlocking tool technical fields, more particularly, to a kind of measuring tool for blade lockset and are based on
The method for unlocking of the measuring tool.
Background technique
Lock is widely used in daily life, needs that key is cooperated to use, key is then carried.In carrying process,
People often occur the thing of key drop, when this thing happens, except the structures such as part of price low in price padlock are simple
Lock can be damaged simply by violence opened easily for cost it is outer, it is necessary to ask locksmith's on-site maintenance, opened by technology
The mode of lock opens lockset and prepares key.
Existing blade lock includes lock tube, lock core, blade group and key.Wherein blade group is by blade and leaf spring group
At, blade group is located in the vane hole of lock core, and the lock to match with blade tip is opened up on lock tube inner wall cheats, blade position when sealed
Lock core and lock tube are locked between the vane hole of lock core and the lock hole of lock tube, prevent lock core from rotating relative to lock tube；It unlocks
When by key after the insertion of core center, wave channel tooth on the key drives corresponding blade mobile, cheats the lock of blade and lock tube
It separates and fully enters in the vane hole of lock core, so that lock core be allow to rotate relative to lock tube, achieve the purpose that unlocking；At present
There is no good method for unlocking for blade lock in the market, it is most by the way of violence unlatching, it is exactly that directly lock core is bored
The lock core that head more renews after destroying to client, directly contributes the wasting of resources, increases the single cost of client；A small number of technology unlockings
Method, although may be implemented to open, difficulty is higher, some need to make repeated attempts, single success rate is low, and unlatching needs the time
It is long.
In view of the above technical problems, it therefore needs to improve.

Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention.
As shown in Figs. 1-5, a kind of measuring tool for blade lockset, including measuring device 1, locating rod 2 and guide rod group
Part 3；Guide rod component 3 includes preceding guide rod 4 and back-guiding rod 5；Preceding guide rod 4 is fixedly connected with back-guiding rod 5, and the side wall of locating rod 2 is along it
Length direction offers guide groove 6, and the preceding guide rod 4 of guide rod component 3 is contained in guide groove 6, slides back and forth along guide groove 6,
And the outer end of the preceding guide rod 4 and the outer end of locating rod 2 are on same perpendicular；The back-guiding rod 5 of guide rod component 4 passes through measurement
Device 1, the sliding distance for guide rod 4 before measuring；The device is easy for installation, positions the guide pad of boom end for catching on lockhole
Inside most the inside blade, by the fixed back-guiding rod end of handle, so that guide rod slides in guide groove before driving, mobile distance exists
It is shown in measuring instrument, blade is successively caught on by guide pad one by one, it is then inconsistent one by one by preceding guide rod and blade,
The data of guide rod before being stirred every time by measuring instrument records；The data recorded every time by measuring instrument, dispatching one is new key
Spoon opens lockset, and the present invention can open blade lock, and tool proposed by the present invention does not need special gimmick and skill, disobeys yet
Rely in subjective judgement, is not also influenced by the spring state of lockset intra vane, as long as lockset is in the openable health status of key,
It carefully operates, can open it by above-mentioned steps, it is very useful, it is convenient.
The front end of locating rod 2 is provided with the guide pad 7 of at least one outwardly convex, guide pad 7 and the fixed company of locating rod 2
It connects, is integrally formed；The structural strength and entire firmness of the device are increased, so that the accuracy of measurement is higher.
The front side edge of locating rod 2 is inclined bevel edge 2-1, i.e., the front side edge of locating rod 2 from the front to the back, gradually rolls upwards
Tiltedly, the tilt angle of bevel edge 2-1 is consistent with the tilt angle of guide pad 7；This improvement structure makes locating rod 2 in insertion lockhole
When, the sliding of blade outside core hoodle hole direction can be smoothly pushed, and the guide pad 7 of 2 front end of locating rod is guided smoothly to be inserted into lock
Hole most the inside；The tilt angle of bevel edge 2-1 and the tilt angle of guide pad 7 are 30 °, 40 °, 45 ° and 60 °；The present invention uses
45°。

Piece, and be adjacent to blade-side；Blade by lockhole extruding and shrink so that the guide pad 7 of 2 end of locating rod is fully inserted into lockhole
It is interior；
Step 2: after insertion, the guide pad 7 of 2 end of locating rod is led for catching on most the inside blade in lockhole by driving lever
Bar assembly 4, so that preceding guide rod 4 and back-guiding rod 5 are mobile；
Step 3: when current guide rod 4 is moved to innermost blade, preceding guide rod 4 is inconsistent with blade, i.e., blade is moved to
Guide rod component 4 is stirred in position, stopping, and preceding guide rod 4 is remain stationary under blade effect；Then, pass through the measuring instrument on measurement seat 11
Device 10 records data；
Step 4: the guide pad 7 of 2 end of locating rod being stirred outward, catches on blade one by one, then passes through preceding guide rod 4
It is inconsistent one by one with blade, the data of guide rod 4 before stirring every time are recorded by measuring instrument 10；
Step 5: when all blades in place when, locating rod 2 is extracted out of lockhole, locating rod 2 is separated with lockhole；
Step 6: new key is opened lockset by the data recorded every time by measuring instrument 10, dispatching one.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention；Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
Although appended drawing reference in figure is used more herein: measuring device 1, locating rod 2, guide rod component 3, preceding guide rod 4,
Back-guiding rod 5, guide groove 6, guide pad 7, attachment base 8, horizontal part 8-1, vertical component effect 8-2, holding tank 9, measuring instrument 10 measure seat
11, handle 12, limit threaded rod 13 waits terms, but it does not exclude the possibility of using other terms；Only using these terms
It is to be more convenient to describe and explain essence of the invention；Being construed as any additional limitation is all and this hair
What bright spirit was disagreed.
