Description
Technical field
The utility model relates to a kind of lock, especially a kind of well lid special-purpose machinery theft-proof lock.
Background technology
Therefore the stolen incident of well lid often takes place owing to there is not lockset in the maintenance well lid of pipelines such as existing sewer pipe, electrical conduits.Well lid is stolen not only can to cause direct damage to property to society; and usually can allow the people fall in the well or the initiation traffic accident; cause casualties thus, under many circumstances, the stolen indirect destruction of causing of well lid is often also serious than direct economic loss.But locksets such as existing door lock can not directly apply to well lid, so, for fear of causing above-mentioned serious consequence, be necessary to provide a kind of well lid special-purpose theft-proof lock that is applicable to manhole cover anti-theft.
The utility model content
The purpose of this utility model promptly provides a kind of well lid special-purpose machinery theft-proof lock.
Well lid special-purpose machinery theft-proof lock of the present utility model has lock housing and the tapered end that is fixed on the lock housing, in tapered end, be equipped with lock core, the two ends of described lock core have keyhole and dead bolt drive link respectively, it is characterized in that being provided with travelling gear, first locking bar and second locking bar, described travelling gear is arranged in the lock housing, described dead bolt drive link is nested with or is fixed in the axis part of travelling gear and travelling gear implement is driven, described first locking bar and second locking bar be arranged in parallel and lay respectively at the both sides of travelling gear, has the driving cog that is provided with along the locking bar long axis direction on described first locking bar and on second locking bar respectively, driving cog and the driving cog on second locking bar on described first locking bar all are meshed with the gear teeth of travelling gear, and the two ends of the two ends of described first locking bar and second locking bar pass lock housing respectively and extend to outside the lock housing.
When using well lid special-purpose machinery theft-proof lock of the present utility model, lock housing can be fixed on the well lid.When fixing lock housing, can realize being connected of lock housing and well lid by the connector of peripheral hardwares such as clip.Certainly, similarly well lid syndeton such as connecting hole or engaging lug can be set on lock housing also, utilize connectors such as the bolt of this well lid syndeton and peripheral hardware or clamp to combine, lock housing is fixed on the well lid.The well lid that is used with product of the present utility model should have keyhole, when fixing lock housing, and the keyhole that allows keyhole on the lock core on well lid, be provided with.Like this, when the keyhole that is provided with from well lid with key stretches into and this theftproof lock is closed, the dead bolt drive link can drive travelling gear and rotate, and drive the motion of first locking bar and second locking bar thus, allow the end of first locking bar and second locking bar stretch in the borehole wall of walling crib bottom of inspection-pit, so with Manhole cover lock on the borehole wall.When the maintainer need open well lid, only need open the lock with the key, allow the end of first locking bar and second locking bar withdraw from and get final product from the borehole wall.
In the utility model, for the ease of making, packing and shipping products, can allow first locking bar and described second locking bar by two sections formations that are threaded, also be the equal of that the extension bar that is threaded is set on first locking bar and second locking bar.
In order to increase the locking intensity of this theftproof lock, the first locking bar supporting base group and the second locking bar supporting base group are set up in the utility model special recommendation in this product, all has a locking bar supporting base at least in the described first locking bar supporting base group and the second locking bar supporting base group, offer the locking bar support holes that can supply locking bar to penetrate on the described locking bar supporting base, described locking bar supporting base is provided with the well lid connecting hole, described first locking bar passes the locking bar support holes on the locking bar supporting base in the first locking bar supporting base group, and described second locking bar passes the locking bar support holes on the locking bar supporting base in the second locking bar supporting base group.Like this, when using product of the present utility model, the locking bar supporting base in the first locking bar supporting base group and the second locking bar supporting base group can be fixed on the well lid.Because locking bar has passed the locking bar support holes on the locking bar supporting base, therefore, the locking bar supporting base can play the effect to locking bar guiding and supporting.What is more important: the supporting of the locking bar supporting base by having certain altitude, can make way for the keyhole apart from each other that is provided with on keyhole on the lock core under the well lid and the well lid, promptly can only could open this theftproof lock, thereby prevent that effectively the burglar from using this theftproof lock of normal key runin with the long special key of the shank of the key.In the utility model, the quantity of the locking bar supporting base that comprises in the first locking bar supporting base group and the second locking bar supporting base group can be chosen according to actual needs, as chooses one, two or three or the like.
In addition, can also allow the above-mentioned locking bar supporting base be upper and lower two sections and locking bar supporting base through being threaded.Like this, just can regulate the height of locking bar supporting base neatly, to adapt to the well lid of different size and model by unscrewing or screw screw thread.
Lock core in the utility model product can be the mechanical billiard lock core, also can be the magnetic marble lock core, can also be the lock core that combines of mechanical billiard and magnetic marble and the lock core of other form.
In the utility model, described dead bolt drive link is nested with or is fixed in the axis part of travelling gear and travelling gear implement is driven.That is to say, the dead bolt drive link both can be nested with the axis part at travelling gear, also can be fixed on the axis part of travelling gear, under preceding a kind of situation, as long as the axle center matching part of dead bolt drive link and travelling gear adopts non-circular cross sectional shape (as rectangle, regular polygon or other shape), just can implement to drive to travelling gear.
Theftproof lock of the present utility model can be conveniently used in manhole cover anti-theft, because it locks well lid with locking bar, thereby has high intensity, fabulous pick-proof and anti-disassembling function, even the burglar damages lock core also and well lid can't be opened and be stolen; Simultaneously, when being provided with locking bar supporting base group, the locking bar supporting base in the locking bar supporting base group will make whole latch-up structure more firm.In addition, after product of the present utility model has been installed, be at theftproof lock under the state of locking, the locking bar in this product can also assist well lid to bear the pressure on top; Even well lid is damaged because of the external force effect such as being rolled, the existence of locking bar and locking bar supporting base also helps to prevent subsiding and falling of well lid.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
