Description
Technical field
The present invention relates to design and the processing technique field of lockset, particularly relate to a kind of theft-proof press lock.
Background technology
At present, on furniture, cabinet sliding door and the theft-proof press lock that building doors and windows is is extensively installed and used, solve well push-pull door sash close after and open certain interval state time locking control problem, and be easy to usely easy to operation, it mainly comprise the band lock housing of firm banking, reference column, lock core shell, lock core.Reference column is one with the cylinder of tapering, be fixed on lock core shell by interference fixed form, control lock core in the detent that the sub-fraction of its lower end is actively plugged in lock core and do not depart from lock core shell, its upper end is given prominence at the outer and strip spacing hole be arranged in lock housing of lock core shell, lock continually along with theft-proof press lock and open, reference column upper end constantly with the rear end collision of strip spacing hole, the reference column be fixed on lock core shell by interference is made to occur to loosen and outwards exit gradually, the detent of lock core that finally caused reference column lower end to depart from, lose the control to lock core, lock core is come off from lock core shell, one is that to shorten application life of theft-proof press lock short, two is dangerous.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of lock core and does not come off the safe and reliable theft-proof press lock of long service life.
The object of the invention is to be implemented by following technology bill:
A kind of theft-proof press lock, it mainly comprises lock housing, reference column, lock core shell and the lock core of being with firm banking, it is characterized in that one side of strip spacing hole in lock housing is provided with a breach, reference column is its upper end of bolt structure is the nut of non-circular structure, screw thread is provided with in fixing hole on lock core shell, reference column is fixed on lock core shell by the screw thread in fixing hole, and the nut of its non-circular structure sinks in strip spacing hole.
Above-mentioned breach is separately positioned on the opposite position on strip spacing hole both sides.
The nut of above-mentioned non-circular structure is oval, square or hexagon.
The shape of above-mentioned breach is arc, square or V-arrangement.
The present invention compared with prior art, there is following outstanding substantive distinguishing features and significant progress: one is the technological gap that design scheme of the present invention has filled up industry field, people are broken for a long time to the traditional understanding of reference column fixed form on theft-proof press lock, two is that the screw thread of reference column on lock core shell is fixing fixes easy operation than interference and can not impact lock core, three is that the screw thread of reference column is fixing than interference fixing-stable, four is rotations that the side on strip spacing hole both sides prevents reference column while the nut containing reference column upper end non-circular structure slides, thus ensured that theft-proof press lock reference column in long-term use procedure can not reverse to exit, make the lower end of reference column can not depart from the detent of lock core, the fault that lock core comes off would not be there is again in theft-proof press lock, not only extend the application life of theft-proof press lock, and it is safe and reliable.

Detailed description of the invention
With reference to the accompanying drawings, provide the specific embodiment of the present invention, be used for that the present invention is further illustrated.
Embodiment 1
The present embodiment take sliding sash as the embedded installing type theft-proof press lock (see accompanying drawing 1 to accompanying drawing 4) that objective for implementation designs.The embedded installing type theft-proof press lock of sliding sash, it mainly comprises lock housing 1, reference column 2, lock core shell 3 and the lock core 4 of being with firm banking D, containing lock core shell 3 and turriform spring 15 in lock housing 1, turriform spring 15 is enclosed within the locking bolt 15 of lock core shell 3 front end, containing location-plate 13 and cylindrical spring 14 in lock core 4, reference column 2 is fixed on lock core shell 3, and the sub-fraction of its lower end is actively plugged in the detent 17 of lock core, and its upper end is given prominence at the outer and strip spacing hole 10 be arranged in lock housing of lock core shell 3.
In the present embodiment, firm banking D is arranged on the front end of lock housing 1 and every side is provided with a fixing hole K.Reference column 2 is bolt structure, its upper end is elliptical screw cap 5, elliptical screw cap 5 is provided with a word recess 6, the length of elliptical screw cap 5 is a, width is b, its cylinder is provided with screw thread 7, and the length of reference column 2 is set to when in the detent 17 that its lower end is actively plugged in lock core 4, and the elliptical screw cap 5 of its upper end just all sinks in strip spacing hole 10.Fixing hole 8 inwall on lock core shell 3 is provided with screw thread 9, and screw thread 7 matches with screw thread 9.Strip spacing hole 10 and locating hole 11 lay respectively at the relative both sides of lock housing 1, an arc notch 12 is established on a limit of strip spacing hole 10, ultimate range between arc notch 12 and another side is d, the width of strip spacing hole 10 is set to c according to the width b of reference column 2 upper end elliptical screw cap 5, c is more bigger than the width b of elliptical screw cap 5, i.e. b < c, the length a of elliptical screw cap 5 is larger than the width c of strip spacing hole 10, be that d is smaller than the ultimate range between arc notch 12 and another side, i.e. c < a < d, when only rotating in arc notch 12 position when reference column 2 is fixed on lock core shell 3 by screw thread like this, the elliptical screw cap 5 of its upper end could rotate and sink in strip spacing hole 10, all can not rotate at other position elliptical screw cap 5 of strip spacing hole 10, in such lock housing 1, the side on strip spacing hole 10 both sides is while containing elliptical screw cap 5 slide anteroposterior, also limit the rotation of elliptical screw cap 5, the rear end of strip spacing hole 10 and A end are the arc matched with elliptical screw cap 5.
Lock core 4, location-plate 13 and cylindrical spring 14 match inserts in lock core shell 3, turriform spring 15 is enclosed within locking bolt 16 inserts in lock housing 1, fixing hole 8 is adjusted in the position of arc notch 12, inserting with " word " screwdriver in the recess 6 on elliptical screw cap 5 to rotate clockwise just is screwed into reference column 2 in fixing hole 8, reference column 2 is just fixed on lock core shell 3 by screw thread, adjusting its lower end is actively plugged in the detent 17 of lock core 4, the elliptical screw cap 5 of its upper end just all sinks in strip spacing hole 10, the length of elliptical screw cap 5 to adjusting to the direction suitable with strip spacing hole 5 one, such theft-proof press lock just can lock and open, just constitute the theft-proof press lock designed by the present invention.
The elliptical screw cap 5 of reference column 2 upper end along with theft-proof press lock unlatching and be locked in slide anteroposterior in strip spacing hole 10, elliptical screw cap 5 slips over instantaneously through arc notch 12 place in sliding process, elliptical screw cap 5 does not also have enough time to produce to rotate and has just slipped over arc notch 12 place, so the elliptical screw cap 5 of reference column 2 upper end in sliding process because the restriction being subject to strip spacing hole 10 liang of flank side surface can not be rotated, reference column 2 exits so just can not reverse, its lower end would not depart from the groove 17 of lock core 4, the fault that lock core comes off would not be there is in theft-proof press lock, also just ensure that the safety of theft-proof press lock, extend the application life of theft-proof press lock.
