A left and right sheet is provided with a molded chute and a molded guide slot, a lingual plate of a master lock is riveted with a guide post inserted into the guide slot, a lock shell is riveted with a sliding post inserted and sleeved in the chute, the left and right sheet is provided with a molded row rack, the auxiliary cylinder is formed by a gear, a connecting sheet and an arc sheet, the connecting sheet is assembled at the lower part of the gear and is integrated with the arc sheet through glue injection, the auxiliary cylinder is hinged on the lock shell by taking the axis of the gear as a center, the row rack is meshed with the gear, acting force on one end of a torsional spring is acted on a lock shell riveting pin, acting force on the other end of the torsional spring is acted on the auxiliary cylinder, and the arc sheet extends out from a preset hole on a side panel. The antitheft lock with the auxiliary cylinder comprises three locking positions on a main spring bolt, a movable spring bolt and the auxiliary cylinder, and six locking points and has the advantages of good anti-lockpick performance and enhanced antitheft function.
Description
Technical field
The utility model belongs to the theftproof lock technical field, especially relates to a kind of theftproof lock that has secondary tapered end.
Background technology
Generally have main dead bolt, movable dead bolt and insurance dead bolt on the existing theftproof lock, drive mechanism is simple, can open or close main jam plate fast, though have anti-theft feature preferably,, when the people gos out, have only two locking positions of main dead bolt and movable dead bolt, theftproof performance has much room for improvement.
The utility model content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of theftproof lock with secondary tapered end, when going out, it has main dead bolt, movable dead bolt and three locking positions of secondary tapered end, six locking points, the pick-proof performance is good, has strengthened the anti-theft feature of theftproof lock.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of theftproof lock with secondary tapered end, comprise lock housing, main bolt plate and about sheet, about on the sheet moulding place chute and guide groove are arranged, rivet guide pillar on the main bolt plate, the guide pillar sleeve is in guide groove, moulding place has the riveted joint traveller on the lock housing, the traveller sleeve is in chute, about on the sheet moulding place one tooth-arranging strip is arranged, secondary tapered end is by gear, brace and arc-like sheet are formed, and brace is molded over the bottom of gear, brace and arc-like sheet pressure injection are one, secondary tapered end is that center hinge is connected on the lock housing with the axis of gear, and tooth-arranging strip is meshed with gear, and torsion spring one end active force is in the lock housing rivet pin, other end active force is in secondary tapered end, and arc-like sheet stretches out the default hole on lock housing and side panel.
Described guide groove is oblique stroke groove, and the torsion spring active force is on the arc-like sheet of secondary tapered end.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is:
1, it has main dead bolt, movable dead bolt and three locking positions of secondary tapered end, six locking points, and the pick-proof performance is good, has strengthened the anti-theft feature of theftproof lock.
2, its theftproof lock improves on existing theftproof lock and has strengthened two locking positions, the superior safety of burglary-resisting system, and this structure manufactures a finished product low, assembling and repair simply, novel secondary tapered end has adopted gear and tooth-arranging strip meshing relation.Coefficient of friction is little at the volley, and sound is little.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation that secondary tapered end of the present utility model is positioned at closed condition;
Fig. 2 is the structural representation that secondary tapered end of the present utility model is positioned at opening.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see Fig. 1, shown in 2: a kind of theftproof lock with secondary tapered end, comprise lock housing 1, main bolt plate 5 and about sheet 2, about form chute 22 and guide groove 23 on the sheet 2, riveted joint guide pillar 51 on the main bolt plate 5, guide pillar 51 sleeves are in guide groove 23, the moulding riveted joint has traveller 11 on the lock housing 1, traveller 11 sleeves are in chute 22, about on the sheet 2 moulding place one tooth-arranging strip 21 is arranged, secondary tapered end 3 is by gear 31, brace 32 and arc-like sheet 33 are formed, and brace 32 is molded over the bottom of gear 31, brace 32 is an one with arc-like sheet 33 pressure injections, secondary tapered end 3 is that center hinge is connected on the lock housing rivet pin 1 with the axis of gear 31, and tooth-arranging strip 21 is meshed with gear 31, and torsion spring 4 one end active forces are in lock housing rivet pin 1, other end active force is in secondary tapered end 3, and arc-like sheet 33 stretches out the default hole on lock housing 1 and side panel.
Described guide groove 23 is oblique stroke groove, and torsion spring 4 active forces are on the arc-like sheet 33 of secondary tapered end 3.
Operating principle: see shown in Figure 1, when main dead bolt need be locked, main bolt plate 5 travels forward, sheet 2 moved leftwards and rightwards about guide pillar 51 promoted, about sheet 2 rack drives gears 31 clockwise rotate, secondary tapered end 3 rotates, and forms state as shown in Figure 1 at last, stretches out with main dead bolt the default hole of arc-like sheet 33 on lock housing 1 and side panel and locks synchronously.
When the people went out, the insurance dead bolt on main bolt plate 5 left sides was not generally locked, and has only the people when indoor, just can remove lock insurance dead bolt, thus the utility model say exactly, when going out, produced six locking points.
