Abstract
To provide lock-unit assembling structure resisting the forced extraction of a lock unit. A thick guard collar section 12 is formed extending over the whole circumference on the inner circumferential surface of the intermediate section of a shaft cylinder section 7, and an angle control projection controlling the rotary range of a rotor 11 is formed on the rear surface side of the guard collar section 12. A thick angle control disk 14 brought into contact with and separated from the angle control projection is fitted to the square shaft section 11a of the rotor 11, the peripheral section of the angle control disk 14 is abutted against the rear surface of the guard collar section 12, and a nut 16 for fixation screwed to the screw shaft sect.
Description
The present invention relates to the locking device that bloats (ボ Star Block ア ケ ト) formula door lock handle that a kind of automatic vending machine etc. is adopted.
Generally speaking, the convex door lock handling device that adopted of automatic vending machine class: interior cover rotatable and that can not move forward and backward is installed in the bearing holder (housing, cover) that is fixed in the fixed housing on the door; The stop steel plate is fixed on the back of overlapping in this; By spring make non-rotatable and can before and after slide, be intercalated in the axle sleeve of handle in the cover have to stretching out taking advantage of a favourable situation that direction moves; The tapered end unit is embedded and is fixed in this axle sleeve; Make the rotor of tapered end unit and the lockable mechanism interlock of internally overlapping mutually with the axle sleeve locking.
Recently, the theft crime of automatic vending machine class is had the tendency of implementing violence, method therefor is: tapping screw is screwed into firmly in the keyhole of tapered end unit rotor, nail pulling is hung over the head of this tapping screw with crowbar, the tapered end unit is extracted from axle sleeve.Because this tapered end unit is extracted by force, handle projects to the position of rotatable operation, so door is illegally opened, is kept at inner article or money and is seized easily.
Therefore, the object of the present invention is to provide a kind of to extracting the locking device of the resistive convex door lock handle in tapered end unit by force.
If adopt the reference number in the accompanying drawing to describe, the structure of the locking device of convex door lock handle then of the present invention is: interior cover 4 rotatable and that can not move forward and backward is installed in the bearing holder (housing, cover) 3 that is fixed in the fixed housing 2 on the door 1; Stop steel plate 5 is installed in the back of interior cover 4; With non-rotatable and can before and after axle sleeve 7 intercalations of the handle 6 that slides in interior cover 4; By spring 8 axle sleeve 7 is had to stretching out the trend that direction moves; Tapered end unit 9 is embedded and is fixed in the axle sleeve 7; Make the rotor 11 of tapered end unit 9 and internally overlap 4 lockable mechanism 10 interlocks mutually, it is characterized in that: the whole full week that heavy wall separated flange part 12 is arranged on axle sleeve 7 middle inner peripheral surfaces axle sleeve 7 lockings; The angle limits projection 13 of restrict rotor 11 rotating ranges is arranged on the back of separated flange part 12; To connect on the 11a of square shaft portion that the heavy wall angle limit disk 14 of melting, separating is embedded in rotor 11 with angle limits projection 13; Make the circumference of angle limit disk 14 be connected to the back of separated flange part 12; Make the fixing back that is connected to angle limit disk 14 with nut 16 that screws on the screw spindle part 11b of rotor 11.
Fig. 1 is the front view of locking device of convex door lock handle that adopts the tapered end unit internal construction of one embodiment of the invention.
Fig. 2 is the sectional view of the A-A line of Fig. 1.
Fig. 3 is the sectional view of the B-B line of Fig. 2.
Embodiment shown in the figure, internal face 15a, the 15b by angle limit disk 14 notch parts 15 with end wall surface 13a, the 13b of angle limits projection 13 contact, separate, the anglec of rotation of rotor 11 is limited in 90 degree.The screw spindle part 11b of rotor 11 makes elliptic cross-section, make itself and connector 17 1 in the same way the lockable mechanism 10 of connecting bushing 7 be embedded into pivotally.
Screw, fixing retainer ring 18 on the main body of tapered end unit 9, the fork-shaped foot 21 of the detent joint 20 of U font inserts from 2 lateral openings 19 of the axle sleeve 7 of handle 6, and 2 inner surface projections 22 of foot 21 are stuck on 2 external surface grooves 23 of retainer ring 18.
As mentioned above, the locking device of convex door lock handle of the present invention is owing to be provided with heavy wall separated flange part 12 on the middle inner peripheral surface of handle 6 axle sleeves 7; Be provided with the angle limits projection 13 that is used for the anglec of rotation of rotor 11 is limited in certain limit in the back of separated flange part 12; To be embedded on the 11a of square shaft portion of rotor 11 with the heavy wall angle limit disk 14 that angle limits projection 13 contacts, separates; Make the circumference of angle limit disk 14 be connected to the back that isolates flange 12; Make the fixing back that is connected to angle limit disk 14 with nut 16 that screws on the screw spindle part 11b of rotor 11, therefore can bear the withdrawal force that thief's crowbar by force applies, isolating flange 12 or angle limit disk 14 can flexural deformation or fracture, tapered end unit 9 can not be pulled out, and can obtain sufficiently high theftproof.
The locking device of the convex door lock handle of second invention, owing to design the appearance and size of nut 16 bigger than the internal diameter of separated flange part 12, so, the circumference of nut 16 is connected to as backing plate on the periphery of angle limit disk 14, extracts stronger resistance to what thief's crowbar by force applied.
