Abstract
The utility model relates to an inspection well cover locking device. An inspection well cover is provided with a lock hole, and a lock sleeve sharing a central line with a lock hole depends on a bolt to be installed on the bottom surface of the inspection well cover. The big end of a rotating shaft is a spline head which is located at the upper end of the lock sleeve during unlocking time, and the outer diameter of the spline head is larger than the diameter of an inner hole at the lower end of the lock sleeve. The small end of the rotating shaft is inserted to the inner hole at the lower end of the lock sleeve in a clearance fit mode, and the lower end of the rotating shaft extending out of the lock sleeve depends on a locating pin to be fixedly connected with a lock plate. One end of a bent handle is provided with a spline sleeve, an inner spline of the spline sleeve is matched with the spline head of the rotating shaft in a sliding mode, and the outer diameter of the spline sleeve is matched with an inner hole at the upper end of the lock sleeve in a sliding mode. The lock plate corresponds to and matches with a groove of a ring seat of the inspection well cover in position and size. The bent handle is rotated, the lock plate enters the corresponding groove, and the inspection well cover is locked. Unlocking is achieved by rotating reversely. Unlocking can only be achieved by adopting the matched bent handle so that theft and recovery of the high-priced inspection well cover with ordinary tools can be effectively avoided.
Description
Technical field
The utility model relates to a kind of locking device, and particularly a kind of Inspection shaft cover lock is decided device.

At present, the manufacturing materials of inspection shaft lid is of a great variety, the short-life situation of ubiquity; By contrast; The ductile iron inspection shaft is being stamped heat resistanceheat resistant, cold-resistant, anticorrosive, good, the long-lived advantage of resistance to compression load-bearing property, but because its recovery price is higher, very easily stolen.
Summary of the invention
The technical problem that the utility model will solve provides a kind of stolen Inspection shaft cover lock of inspection shaft lid that prevents and decides device.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of Inspection shaft cover lock is decided device; Comprise being provided with to carry and cover the inspection shaft lid that Kong Bingyu inspection shaft decorative cover seat cooperates, said inspection shaft lid also is provided with lockhole, and the lock tube that has center line with lockhole relies on bolt to be installed in the bottom surface of inspection shaft lid; The big end of rotating shaft is the spline head, and the spline head is positioned at the upper end of lock tube, and the external diameter of spline head is greater than the lower end diameter of bore of lock tube, and the diameter of lockhole is greater than the external diameter of spline head; The small end matched in clearance of rotating shaft is inserted the lower end endoporus of lock tube, and the rotating shaft lower end of stretching out lock tube relies on alignment pin to be fixedly connected with jam plate; One end of curved handle handle is provided with splined sleeve, and the spline head of the internal spline of splined sleeve and rotating shaft is slidingly matched, and the upper end endoporus of the external diameter of splined sleeve and lock tube is slidingly matched.The other end of said curved handle handle is provided with matched in clearance and can gets into the round pin that covers the hole of carrying of said inspection shaft lid.When said inspection shaft covered a side and is connected with inspection shaft decorative cover seat hinge, Inspection shaft cover lock was decided the opposite side that device is installed in inspection shaft decorative cover seat, and when said inspection shaft lid was not connected with inspection shaft decorative cover seat, Inspection shaft cover lock was decided the both sides that the device symmetry is installed in inspection shaft decorative cover seat.The position of the groove of said jam plate and inspection shaft decorative cover seat and the mutual corresponding matching of size when unblanking, are inserted and rotated said curved handle handle, and jam plate gets into corresponding each other groove, locking inspection shaft lid; Counter-rotating can be unblanked.
The beneficial effect of the utility model is:
Since the internal spline of the splined sleeve of curved handle handle cooperate with the spline head of rotating shaft; The external diameter of splined sleeve cooperates with the upper end endoporus of lock tube; So have only supporting curved handle handle could get into the upper end endoporus of lock tube,, rotate jam plate and unblank with the spline head engagement of rotating shaft; Prevent to adopt general purpose tool to steal effectively and reclaim the higher inspection shaft lid of price.
2. the other end of curved handle handle is provided with matched in clearance and can gets into the round pin that cover hole of carrying of inspection shaft lid, after unblanking, the round pin of curved handle handle is inserted to carry cover the hole, rotates an angle, is convenient to mention heavy inspection shaft and covers.
3. the utility model can prevent that inspection shaft lid is stolen, prolongs its application life, avoids the inspection shaft lid stolen and security incident that cause is replenished the required manpower and materials of inspection shaft lid with practicing thrift.
4. the anti-theft feature of the utility model can promote the extensive use of ductile iron inspection shaft lid; Give full play to its heat resistanceheat resistant, cold-resistant, anticorrosive, the resistance to compression load-bearing property is good, durable in use and be convenient to inspection shaft lid to make it combine tightr stable advantage with inspection shaft decorative cover seat along polishing processing.
