Fig. 2 is the lock a door schematic diagram of watch box of the utility model pipe well.

The specific embodiment

In order further to set forth the utility model pipe well lock, do more detailed explanation below in conjunction with embodiment.

Figure 1 shows that the structural representation of the utility model pipe well lock.Pipe well is locked by panel 3, upward lock housing 4, following lock housing 5 and dead bolt 9 are formed.On following lock housing 5, fix a lock tongue supporting column 6, spring hanging column 7 and the joint pin 11 of lock housing 4,5 up and down; Dead bolt 9 is that the dead bolt hole on a cuboid and the panel 3 matches, and there is a narrow slightly thin slightly extension 17 dead bolt 9 back, has one and the chute 15 of set support column 6 correspondences on extension 17, and there is a recess 16 lower edge; There is circular hole lock housing 4,5 belows up and down, and position and spring hanging column 7 are on the same vertical line; Lay key thumb wheel 14 between two holes, thumb wheel 14 has the recess 16 on a protuberance 10 and set 9 to adapt, and also has a spring hanging hole 18 on the thumb wheel 14; One torque spring 8 is arranged between this spring hanging hole 18 and spring hanging column 7.

Panel 3 has two support claws 13 and 3 of panels to be welded into one.

Before the assembling, in advance lock tongue supporting column 6, spring hanging column 7 and joint pin 11 are fixed on down on the lock housing 5.

During assembling, panel 3 assemblies (chord support claw 13) are placed down on the lock housing 5, dead bolt 9 places the dead bolt hole of panel 3, chute 15 on the dead bolt 9 is enclosed within on the lock tongue supporting column 6, put the short sleeve 19 that prevents that dead bolt 9 from teetertottering, again thumb wheel 14 is placed down in the corresponding circle hole of lock housing 5, the recess 16 that protuberance 10 on the thumb wheel 14 is aimed on dead bolt 9 extensions 17, lay spring 8 between the spring hanging hole 18 and spring hanging column 7 on the thumb wheel 14, two of torque spring 8 is inserted and is reserved in the aperture, cover lock housing 4, two holding screws on fixedly connected post 11 and the lock tongue supporting column 6 get final product.

One deep hole is arranged on the thumb wheel 14, a square bar 12 is arranged in the hole, its end face is lower than the outer guard ring of thumb wheel 14.Square shrinkage pool key with special entangles square bar 12, twists key left, and thumb wheel 14 turns left, and its protuberance 10 by the recess on the dead bolt extension 17 16, promotes dead bolt 9 extending panels to anticlockwise.

Because the dead bolt hole on the panel 3 and and the dual qualification of the chute 6 that cooperates of lock tongue supporting column 6, and the qualification of short sleeve 19, dead bolt 9 can only before and after translation, reach locked purpose.

Because the end face of square bar 12 is lower than the outer turns of thumb wheel 14, the hole on the thumb wheel 14 is darker again, so under the situation without private key, be difficult to unblank with other thing.

With the corresponding doorframe of the door that lock body is installed on, a watch box sheet 2 is installed, make of steel plate, guarantee the reliability of locking a door, the plastic casing 1 of a protection usefulness is arranged in door watch box sheet 2 back, stay the space of abundance for dead bolt 9.

The pipe well lock of present embodiment, structure is very simple, has only very few several parts during assembling, uses reliably, and special-purpose square hole key can be opened all locks, but under the situation that does not have special-purpose square hole key, it also is very hard driving this lock.This just provides a kind of suitable, simple, reliable, firm lockset for the property management of communal facility, is very suitable for this specific applications and promotes.
