Description
Technical field
The utility model relates to a kind of antitheft and antifreeze Cover of inspection well with lock.
Background technology
At present, known Cover of inspection well (Cover of inspection well is meant the reusable well head closure of underground inspection shafts such as Shang Shui, Xia Shui, heating power, communication, electric power) is lost easily, causes losing with destroyed of the interior equipment of potential safety hazard and inspection shaft.Though some Cover of inspection well with lock can play certain antitheft effect, but because simplicity of design, be easy to be opened and lost due antitheft effect, again because northern city is colder winter by stealer, well lock easily freezes and bad keying, causes very big trouble for the use of inspection shaft.
Summary of the invention
Non-anti-theft or anti-theft effect is bad in order to overcome existing Cover of inspection well, and antitheft but not antifreeze problem, the utility model provides a kind of Cover of inspection well, this Cover of inspection well can not only play good antitheft effect, and has also obtained good effect on the solution well lid freezes the problem of opening difficulty.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of disc lock is installed in common Cover of inspection well, and this lock is made of parts such as coaxial disc, pull bar, antitheft buttons.Coaxial disc be enclosed within well lid casting all-in-one-piece sleeve in, the part of antitheft button is clamp-oned in the axial wall groove of coaxial disc under the effect of compression spring naturally in the sleeve, and pull bar passes hanging ring and is connected with coaxial disc in the eccentric deep-slotted chip breaker of coaxial disc by connecting bolt.With this utility model the technical characterictic of supporting key be: this key profile is a column, is made of handwheel, gland, power transmission shaft, the parts such as bolt, spanner, key bit, key body that expand.Insert this key in the axle of coaxial disc by the well lid lockhole during use, handwheel on the key, make key bit protrude key body outward and insert in the embedded groove of coaxial disc axial wall and with its interlock, this key bit is simultaneously antitheft button crowded getting back in the axial wall groove of sleeve in the axial wall groove of coaxial disc, mention and pull Key jaw type spanner, make key do the rotation of suitable (contrary) hour hands, driving coaxial disc by key bit rotates together, force the pull bar straight line that in its eccentric deep-slotted chip breaker, is connected with coaxial disc to stretch (contracting) motion, pull bar inserts the bottom of (leaving) cage, has just reached the purpose that goes up (opening) lock.Anti-theft feature of the present utility model is mainly reflected on the antitheft button, the part of antitheft button is embedding under the effect of compression spring in the axial wall groove of coaxial disc at ordinary times, make non-the utility model supporting key even other column inserts or wedging well lid lockhole in coaxial disc is rotated with it, thereby can't unblank.Another characteristics of the present utility model are in the process of last (opening) lock, the moment that produces on coaxial disc during key is very big, it is also very big just to make pull bar do straight-line power, this has just solved northern city because winter severe cold makes Cover of inspection well well lock owing to freeze, the problem of the difficulty of unblanking, lock.(the utility model and institute's matched key, each component title of cage, shape, position are seen accompanying drawing and description of drawings for details)
The beneficial effects of the utility model are: it is stolen that Cover of inspection well is difficult for, and prevents to cause losing with destroyed of equipment in potential safety hazard and the well, solved the problem that Cover of inspection well with lock opens and closes difficulty winter simultaneously.

The specific embodiment
The utility model is to be made of the well lid of circle (1), pull bar (2), connecting bolt (3), sleeve (4), coaxial disc (5), antitheft button (7), compression spring component such as (8).Add and man-hour columniform sleeve (4) and hanging ring (6) are cast into one with well lid (1), and reserve lockhole on well lid top, inner face at well lid (1) is installed to coaxial disc (5) on the sleeve (4) then, pull bar (2) passes hanging ring (6) and is hinged with coaxial disc (5) in the eccentric deep-slotted chip breaker of coaxial disc (5) by connecting bolt (3), in the groove of the part of the antitheft button (7) in sleeve (4) axial wall groove groove embedding coaxial disc (5) in the sleeve (4) under the effect of compression spring (8).With upper-part such as Fig. 1-shown in Figure 16.
The utility model supporting cage such as Figure 17, shown in Figure 180.
The utility model supporting key be by: key body (19), handwheel (10), gland (11), power transmission shaft (12), the bolt (13) that expands, spanner (14), drag knob (15), backstay (16), key bit (17), formation such as extension spring (18) component of etc.ing.The top of the power transmission shaft (12) in the key body (19) is rigidly connected by the handwheel (10) outside nut and the gland (11), the bottom of power transmission shaft (12) is threaded with the internal cavities of bloated bolt (13), the steel disc of bloated bolt (13) lower taper end inserts the top of key bit (17), key bit (17) is under the effect of the extension spring (18) that is connected with key body (19), deflation is in the cavity of key body (19), key body (19) is the cylinder of hollow, spanner (14) is attached to key body (19) outer wall, be connected with key body (19) by bolt, drag knob (15) passes a hole virtual connection of key body (19) chamber wall and power transmission shaft (13) and touches, and backstay (16) is the shaft-like projection at key body (19) outer wall.With upper-part such as Figure 19-shown in Figure 22.
The specific embodiment is exactly: Cover of inspection well is put on the cage (9), with the lockhole on backstay (16) the aligning Cover of inspection well on the key, key is inserted in the Cover of inspection well lockhole, be in the axle of coaxial disc (5), rotate handwheel (10), drive power transmission shaft (12), bloated bolt (13) is moved downward, key bit (17) is extruded key body (19) be raised type, and make key bit (17) enter in the embedded groove of coaxial disc (5) axial wall and, extrude antitheft button (7) simultaneously with its interlock, at this moment, mention spanner (14), key body (19) drives the coaxial disc (5) in the Cover of inspection well, coaxial disc (5) drives pull bar (2) again, pull bar (2) is done rectilinear motion and is inserted Seat for manhole cover (9) bottom under the control of hanging ring (6), locks exactly.It is similar to above-mentioned steps to unblank, and just makes pull bar (2) from the withdrawal of inspection shaft well seat bottom, reaches the purpose of unblanking.In the process of last (opening) lock, when key rotates at lockhole, drag knob (15) embeds the bolt (12) that expands under the extruding of lockhole wall a hole makes the bloated bolt (13) can't be movable, key bit (17) can't be retracted in the groove of lockhole, thereby make key in lockhole, transfer to, have only key to rotate back into initial insertion position, drag knob (15) could be hit by a bullet out from the bolt (13) that expands, so the effect of drag knob (15) is to prevent to pull up key next from Cover of inspection well when the process of (opening) lock from not implemented.The main antitheft characteristics of the utility model are just in antitheft button (7), in the groove of the part of antitheft at ordinary times button (7) embedding coaxial disc of the groove in the sleeve (4) (5) under the effect of compression spring (8) coaxial disc (5) can't freely be rotated, this just use non-the utility model supporting key even other column inserts or the lockhole of wedging Cover of inspection well in coaxial disc (5) is rotated, can't reach the purpose of unblanking, have only key bit (17) to enter when extruding the axial wall groove of coaxial disc (5) in the axial wall groove of coaxial disc (5) and antitheft button (7), at this moment key again, coaxial disc (5) is and then rotated, to realize (opening) lock.
