Embodiment
The preferable embodiment of lock core survey instrument of the present utility model as shown in Figure 1, comprises housing 7, is provided with through hole in the described housing 7, is provided with gage beam 8 and dip stick 4 in the described through hole, and housing 7 preferred design become rectangular-shaped.Gage beam 8 becomes tabular with dip stick 4 preferred design, is installed in the through hole of housing 7 after the two is overlapped.
Described gage beam 8 passes described through hole, and hinged with housing 7, can and the hole wall of through hole one side of housing 7 between hinge 5 is set, also can and the hole wall of the through hole both sides of housing 7 between hinge 5 is set; Described dip stick 4 passes described through hole, and can slide in through hole.
As shown in Figure 2, when hinge 5 was arranged on the hole wall of through hole both sides of housing 7, described dip stick 4 was provided with slotted hole 13, and described hinge 5 passes from slotted hole 13.Neither influence the slip of dip stick 4, do not influence the rotation of gage beam 8 again around hinge 5 along through hole.
Described housing 7 is provided with positioning bead 6; Corresponding described dip stick 4 is provided with a plurality of pilot holes 14.The mode that is provided with is, open an aperture at housing 7, spring of aperture internal fixation, a globule is set between spring and the dip stick, globule is against on the pilot hole 14, make between housing 7 and the dip stick and can not slide easily, when applying enough big external force, positioning bead 6 is transferred on the another one pilot hole 14.
The spacing of the pin in the spacing of described a plurality of pilot hole 14 and the lockhole is identical, can make each pilot hole 14 corresponding to a pin in the lockhole, is convenient to each pin is accurately measured.
The front end of described dip stick 4 is an insertion end 1, the front end of described gage beam 8 is a measuring junction 3, described insertion end 1 and measuring junction 3 length are more than or equal to the degree of depth of lockhole, and described insertion end 1 and height after measuring junction 3 overlaps and width are respectively less than the height and the width of lockhole.Can be inserted into smoothly in the lockhole after being convenient to insertion end 1 and measuring junction 3 overlapping, do not influence relatively moving between insertion end 1 and the measuring junction 3 again.
For measuring junction 3 can not be run in lockhole on the wall of lockhole, the upper edge of described insertion end 1 and lower edge can be provided with flange 12 individually or simultaneously, and measuring junction 3 is movable between upper and lower flange 12.When a upper edge in insertion end 1 is provided with flange 12 is that described measuring junction 3 is located at the bottom of flange 12.
Have a plurality of grooves 11 on the described flange 12, the width of described groove 11 is greater than the diameter of pin in the lockhole; The spacing of described a plurality of groove 11 equals the spacing of pin in the lockhole.So that after insertion end 1 was inserted lockhole with measuring junction 3, the pin in the lockhole dropped in the groove 11, and pin is carried out accurate in locating and measurement.
The end of described measuring junction 3 preferably is provided with projection 2, and described protruding 2 diameter is less than the width of described groove 11.So that projection 2 with the pin jack-up in the lockhole, is measured the height of pin.
The concrete measuring process of lock core survey instrument of the present utility model is such:
At first, the insertion end 1 of dip stick 4 is inserted in the lockhole, mobile shell 7 and gage beam 8 make the projection 2 of the measuring junction 3 of gage beam 8 move to the position of a lock, and the rear portion of described dip stick 4 is provided with vertical rule 15 and horizontal rule 16.Read the depth location of this lock in lockhole by vertical rule 15.
Then, press the rear end of gage beam 8 downwards, projection 2 is lifted lock, and after being raised to suitable height, the horizontal rule 16 at the rear portion by dip stick 4 is read the height of this lock.Mobile shell 7 and gage beam 8 measured to the position of another lock again, and the like, with the degree of depth of all locks in the lockhole with highly all measure.Can be according to the degree of depth of all locks in the lockhole and height, configuration key or provoke lock realizes unblanking.
The rear end of described gage beam 8 preferably is provided with elastic component 9, and the rear end of elastic component 9 is provided with briquetting 10.During measurement, press briquetting 10 downwards, when elastic component 9 bends, be lock and be in suitable height, can guarantee that all locks carry out height with same strength and measure, avoid manually grasping the error of the empirical value of strength.
Another embodiment of the present utility model is, the outside of described housing is provided with displacement detecting instrument 17, automatically measure the length travel and the rotational angle of gage beam 8 by displacement detecting instrument 17, and converse the degree of depth and the height of lock in the lockhole, uses more convenient, measurement is more accurate.
The utility model injects lockhole with insertion end and measuring junction, by moving and rotate gage beam, can measure the degree of depth and the height of pin in the lockhole convenient, accurately.Simple in structure, be applicable to the degree of depth and the height of measuring pin in the various lockholes.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
