Detailed description of the invention
The special port lid of city integrated piping lane shown in composition graphs 1-6, the flick mechanism of after comprising port lid lock and the unblock of port lid 1 lock, port lid 1 being upspring automatically.Flick mechanism comprises being arranged on and flicks spring 7 between port lid 1 and port lid circle 8; When described port lid 1 is closed into port lid circle 8, flicks spring 7 and compressed.When port lid is locked in port lid circle 8, flicks spring 7 and be in stressed compressive state; Namely there is the trend of port lid 1 of upspringing at any time; As long as one unlocks, port lid 1 just automatically can be upspring under the effect flicking spring 7.The spring 7 that flicks shown in Fig. 6 is installed near jointed shaft 80 and is just constituted the simplest flick mechanism.
Described port lid lock comprises: be contained in the lock core 21 on port lid 1, and the end that lock core 21 is positioned at inside port lid 1 connects dead bolt portion 2, and dead bolt portion 2 can drive locking bar 5 to insert in lockhole 6, and lockhole 6 is positioned on port lid circle 8 or hole wall.Return mechanism for driving locking bar 5 to exit lockhole 6 is also set inside port lid 1; And can by fixed mechanism fixing for position, dead bolt portion 2.The opening switch 3 of fixed mechanism is positioned at inside port lid 1, and port lid can be locked and unlock by the key 10 mated with lock core 21 outside port lid 1; Namely remove fixed mechanism fixing dead bolt portion 2.After port lid lock unlocks, return mechanism is enough to drive locking bar 5 to exit lockhole 6.
Because port lid 1 is upspring automatically, therefore port lid 1 outer surface is preferably burnishing surface, smooth in described smooth not absolute sense, but finger-hole lid 1 surface is without the need to arranging lift-pull handle or hole, and edge is also without the need to the reserved gap being convenient to pry open.Therefore when port lid 1 closes, it does not have origin of force, be not easy to be pried open, improve the theftproof performance of port lid 1 greatly.
Return mechanism generally includes the guiding reciprocating tubulose of locking bar 5 or channel-shaped guiding parts, and the elastomeric element such as spring and rubber band exits lockhole 6 for driving locking bar 5.Fixed mechanism has opening switch 3, remove fixed mechanism for operator.Described fixed mechanism can be electromagnetic structure, also can be frame for movement, can also be the structure utilizing air pressure, hydraulic pressure.Described fixed mechanism remove to dead bolt portion 2 fixing after, return mechanism is enough to drive locking bar 5 to exit lockhole 6.
After namely locking bar 5 inserts lockhole 6, the screen resilience of return mechanism works all the time, and dead bolt portion 2 is the external force antagonism screen resiliences by fixed mechanism, maintenance locking bar 5 position.Therefore, as long as fixed mechanism is to the constraint release in dead bolt portion 2, dead bolt portion 2 will action, and remove the driving to locking bar 5, locking bar 5 unlocks.According to substantial technological thinking of the present invention, have many concrete structures and mode to realize above-mentioned functions: such as dead bolt portion 2 and locking bar 5 are all made up of the piston rod of cylinder, fixed mechanism and return mechanism are made up of the source of the gas pipeline of control cylinder source of the gas work, gauge tap.Or dead bolt portion 2 and locking bar 5 are made up of electric pushrod.Corresponding key 10 namely trigger switch.Its feature all must meet these parts and all be positioned at inside port lid 1, and opening switch 3 is positioned at the easy-operating position of hole operator.Be convenient to the inner side uncap from port lid 1; From aperture or be called aperture and escape rapidly, it is large to solve city integrated piping lane inner space, and facility is many, and construction, Ren Yuanduo, risk symptoms node is many, the problem be prone to accidents.
Port lid lockset body preferred structure is such as shown in composition graphs 1-6: described fixed mechanism comprises connecting rod 22 relatively-stationary with position, dead bolt portion 2, and when locking bar 5 inserts lockhole 6, stop the block piece 31 that connecting rod 22 moves, block piece 31 is driven by spring element 32 and keeps the stop to connecting rod 22; The action of described opening switch 3 can remove the stop of block piece 31 pairs of connecting rods 22.Coordinated with opening switch 3 and block piece 31, spring element 32 by connecting rod 22, be convenient to parts on the one hand and arrange assembling, connecting rod 22 can be utilized to play leverage simultaneously, operate more laborsaving.Now, key 10 be band movable lock core 21 and connecting rod 22 away from the structure of block piece 31, or depart from the structure of connecting rod 22 for Direct driver block piece 31.
Be more preferably, described dead bolt portion 2 is oval.Connecting rod 22 to be fixed on lock core 21 and protruding by the side, long limit in dead bolt portion 2, and dead bolt portion 2 and connecting rod 22 can around lock core 21 coaxial rotation.Minor face place of dead bolt portion 2 turns to and during end in contact, locking bar 5 front end is headed into lockhole 6 with in locking bar 5; That is to say that locking bar 5 is headed into lockhole 6 by dead bolt portion 2 length.Described locking bar 5, lockhole 6 and return mechanism are symmetrical arranged two groups.As shown in Fig. 2,5,6, under the effect of return mechanism, connecting rod 22 has and rotates clockwise trend shown in Fig. 2, but is stopped by block piece 31, and therefore locking bar 5 keeps the state inserting lockhole 6.Because during port lid locking lock, dead bolt portion 2 also can not be in absolute equilibrium state, so connecting rod 22 always has the trend of rotation, block piece 31 is blocked in its front of rotating; Or in order to make rotation trend stronger, the position arrangement that block piece 31 coordinates with connecting rod 22 can be had deflection angle position in dead bolt portion 2.When after the stop that block piece 31 is removed connecting rod 22 under opening switch 3 acts on, connecting rod 22 rotates clockwise end in contact in long limit, oval dead bolt portion 2 and locking bar 5, and now two locking bar 5 spacing reduce, simultaneously to the middle resilience of port lid 1, exit lockhole 6, can easily open port lid 1.Now, as long as key 10 energy rotational lock core 21, connecting rod 22 can be made away from block piece 31, realize unlocking.
Fixed mechanism can be promote the mechanism of dead bolt portion 2 displacement along lock core 21 length direction, or the shelly coincide with dead bolt portion 2 profile, away from or rotate near dead bolt portion 2 and realize the control to dead bolt portion 2.Preferably as Fig. 3, described block piece 31 front end is hook-shaped, and connecting rod 22 is blocked in hook-shaped most advanced and sophisticated inner side, and hinged by jointed shaft 34 and port lid 1 in the middle part of block piece 31, block piece 31 rear end coordinates with the opening switch 3 of pressing; Describedly be arranged on the block piece 31 rear end spring contrary with opening switch 3 force direction, upwards press block piece 31 when namely opening switch 3 is work in Fig. 3, the spring element 32 that spring is formed pulls down for screw thread spring.Have jointed shaft 34 in the middle part of block piece 31, therefore left side downwards, and right side is inevitable upwards to keep reliably stopping connecting rod 22.Or spring element 32 is for being arranged on the block piece 31 front end spring identical with opening switch 3 force direction, the spring namely upwards pressed by unci or draw.
As shown in Figure 1, opening switch 3 upwards presses, and upwards, right-hand member moves downward block piece 31 left end.Locking bar 5 has the trend to port lid 1 intermediary movements, connecting rod 22 movement tendency with turn right (Fig. 2 shown in clockwise) corresponding to 2, dead bolt portion.When connecting rod 22 is left in the downward hook-shaped one end of block piece 31 right-hand member, then connecting rod 22 and dead bolt portion 2 rotate clockwise end in contact in shorter one end of size, dead bolt portion 2 and locking bar 5 immediately, and locking bar 5 realizes unlocking.Port lid 1 can be opened.When needing again to pin port lid 1, can from inner side pivot link 22, or from outside with key 10 rotational lock core 21, lock core 21 drivening rod 22 and dead bolt portion 2 are in blocking again.Because block piece 31 end is hook-shaped, no matter so locking time connecting rod 22 clockwise or rotate counterclockwise and can snap in locked position of coupler smoothly.
Can also fix an installing plate 9 (in Fig. 2,5,7,10, installing plate 9 double dot dash line signal, avoids blocking miscellaneous part) inside described port lid 1, installing plate 9 is such as welded with port lid 1 inner plate surface by riser by simple fixed form.Described pressing opening switch 3 is arranged on installing plate 9.Described is fixed on mount pad 33 with the jointed shaft 34 matched in the middle part of block piece 31, and mount pad 33 is fixed on the surface of installing plate 9 towards port lid 1.Described spring element 32 one end coordinates with block piece 31, and the other end is arranged on mount pad 33, moves between mount pad 33 with port lid 1 inner surface from for connecting rod 22.Mount pad 33 and block piece 31 can be avoided like this to interfere with the rotation of connecting rod 22, and the length dimension required precision of connecting rod 22 reduces, and processing is simple, uses also more convenient.
Described return mechanism can adopt various ways, and preferred embodiment mainly contains shown in Fig. 1-6: draw together the guide pipe 4 be fixed on inside port lid 1, and the helical spring 41 in guide pipe 4, and locking bar 5 is through screw thread spring 41; And the shaft position of screw thread spring 41 one end and locking bar 5 is fixed, the other end and guide pipe 4 position are fixed.Or as Figure 10, described return mechanism comprises the guide pipe 4 be fixed on inside port lid 1, and locking bar 5 is sheathed in guide pipe 4; Arrange screw thread spring 41 between described two locking bar 5 the inners, this spline structure is simpler.
For the ease of back and forth opening and locking, described port lid 1 is usual and port lid circle 8 is hinged.Flick mechanism is corresponding to be preferably: described in flick spring 7 and be positioned at articulated position place, and between jointed shaft 80 and port lid circle 8 inside edge, flick spring 7 lower end and be fixed on port lid circle 8, as Fig. 2,5,6.Flick spring 7 like this need not arrange and longly just can ensure that port lid 1 and port lid circle 8 are having enough opening angles.The described spring 7 that flicks adopts larger rigidity Design in the present embodiment, and the rigidity strengthening flicking spring 7 can be accomplished in several ways.Such as use the high material of rigidity to make and flick spring 7, increase the diameter making and flick the steel wire of spring 7.
Specifically add man-hour, for the ease of production and processing, be especially convenient to assemble jointed shaft 80.Described port lid 1 and port lid circle 8 extend radially outward the first connecting portion and the second connecting portion respectively, and described jointed shaft 80 is positioned at the outer end of the first connecting portion and the second connecting portion; The described spring 7 that flicks is between the first connecting portion and the second connecting portion; Flick spring 7 lower end to be fixed on the second connecting portion.The first described connecting portion and the second connecting portion can be welded on port lid 1 and port lid circle 8 respectively, also can be that cast sections is just one-body molded, can also be that anatomical connectivity by arranging dovetail groove is on port lid 1 and port lid circle 8, or all arrange connecting hole on port lid 1, port lid circle 8, first connecting portion 11, second connecting portion 12, then by the mode of bolt-locking.
When port lid 1 needs to open, staff only needs the lock opening port lid 1, and now the first connecting portion and the second connecting portion will be subject to the support force from flicking spring 7.Now, because the second connecting portion is rigidly attached on port lid circle 8, and port lid circle 8 fixes on the ground; Therefore flicking spring 7 will drive the first connecting portion hinged with the second connecting portion to lift, thus drives port lid 1 to lift by the first connecting portion.
In order to improve the stability of device, better way is, described in flick in installing hole 31 that spring 7 is arranged on the second connecting portion.Installing hole 31 not only better can be fixed flicking spring 7, also playing the effect of leading for flicking spring 7 simultaneously, making to flick spring 7 not run-off the straight and deflection.And spring 7 corresponding position can also be flicked on described first connecting portion and be provided with the spring case 41 being enough to cover and flicking spring 7, spring case 41 is positioned at the sharpening tubular of the edge inside port lid 1 higher than outer ledge, and tubular inner chamber thickness is greater than the thickness flicking spring 7.Port lid 1 is generally upspring by the elastic force flicking spring 7, and to make port lid 1 and port lid circle 8 open angle be 15 °-40 °.Spring case 41 also plays the effect of guide-localization, and port lid 1 presses down in process and can cover flicking spring 7, prevents from flicking spring 7 deflection, clamping stagnation, improves the stability run further.And due to the special profile design of spring case 41, it is in active procedure and flick to there will not be between spring 7 and stuckly maybe will flick the situation of spring 7 tape skew, extend the application life flicking spring 7 greatly, also just improve the application life of device entirety.
Or as is seen in figs 7-10, the described spring 7 that flicks arranges one at port lid circle 8 place of side relative to articulated position, and/or is arranged symmetrically with at least two along articulated position and place, port lid 1 center straight line.Be more preferably shown in composition graphs 8, universal ball end 52 is fixed near articulated position place inside described port lid circle 8, the turning end of universal ball end 52 fixes a sleeve 54, helical spring 53 and piston rod 55 is arranged successively in sleeve 54, the external end head of piston rod 55 stretches out sleeve 54 and is positioned at the closing in chute 51 inside port lid 1, and closing in chute 51 is forwards extended by the edge, side of articulated position.Be more preferably, described universal ball end 52, sleeve 54, helical spring 53, piston rod 55 and closing in chute 51 are arranged symmetrically with two groups with articulated position and place, port lid 1 center straight line; The movement locus of described fixed mechanism and piston rod 55 from; Described helical spring 53 two ends are fixedly connected with bottom piston rod 55 and sleeve 54 respectively.The described spring 7 that flicks also is positioned at installing hole 31 on port lid circle 8, on described port lid 1 with flick spring 7 corresponding position and be provided with the spring case 41 being enough to cover and flicking spring 7, spring case 41 is positioned at the sharpening tubular of the edge inside port lid 1 higher than outer ledge.
The namely described spring 7 that flicks arranges one at port lid circle 8 place of side relative to articulated position; Or be arranged symmetrically with at least two along articulated position and place, port lid 1 center straight line.Or all arrange flick spring 7 in articulated position both sides (both sides are exactly the left and right sides of figure in the figure 7), upper end exactly as shown in Figure 7.So, flicking spring 7 by three and have an effect simultaneously, being more prone to regard to making the unlatching of port lid 1 become; Simultaneously the specification of each spring, size, cost can reduce.And force dispersion is flicked to multiple the situation that spring 7 also just decreases fatigue damage after Long-Time Service greatly.
Shell and the port lid circle 8 of universal ball end 52 are fixed, and turning end fixes a sleeve 54, arranges helical spring 53 and piston rod 55 in sleeve 54 successively.The external end head of piston rod 55 stretches out sleeve 54 and is positioned at the closing in chute 51 inside port lid 1, and closing in chute 51 is forwards extended by the edge, side of articulated position.The external end head being convenient to piston rod 55 like this loads closing in chute 51 by port lid 1 edge.
When closedown port lid 1, the external end head of piston rod 55 slides in closing in chute 51, when sliding into topmost position, just starts compression helical spring 53.Continue to close port lid 1, when port lid 1 is depressed into less with port lid circle 8 angle, continue to press down, the deformation that helical spring 53 produces and resistance all almost no longer increase; In this process the feel of operator and closing automobile boot similar.Now port lid 1 just starts and flicks spring 7 and contact, because port lid 1 is less with the angle of port lid circle 8, port lid 1 gravity is maximum to the active force flicking spring 7.Now staff exerts oneself a little, just easily compress flicking spring 7, then being locked by port lid 1.
When opening port lid 1, helical spring 53 has just started also not deformation substantially, by flicking spring 7, port lid 1 is flicked to a smaller angle; Then helical spring 53 continues to work port lid 1 is backed down greater angle.Most descendant lifts port lid 1 gently to opening angle and is more than or equal to 90 °, is preferably greater than 120 °.The present embodiment relies on flick spring 7 elastic force no longer completely; But dependence flicks spring 7 and port lid 1 is upspring by helical spring 53 stage by stage, more laborsaving, more reliable.Meanwhile, by helical spring 53 two ends respectively with spot welding or be otherwise connected and fixed, can ensure that work is smooth and easy, even and if port lid 1 be opened, and the jointed shaft 80 at articulated position place is taken down, and port lid 1 all cannot be removed; Substantially enhance anti-theft effect.This substantially increases the theftproof performance of device undoubtedly, avoids port lid 1 to lose many security incidents of rear initiation.
Be more preferably described universal ball end 52, sleeve 54, helical spring 53, piston rod 55 and closing in chute 51 and be arranged symmetrically with two groups, as shown in Fig. 7,10 with articulated position and place, port lid 1 center straight line.The described spring 7 that flicks is positioned at installing hole 31 on port lid circle 8.On described port lid 1 with flick spring 7 corresponding position and be provided with the spring case 41 being enough to cover and flicking spring 7, spring case 41 is positioned at the sharpening tubular of the edge inside port lid 1 higher than outer ledge, and tubular inner chamber thickness is greater than the thickness flicking spring 7.Such installing hole 31 and spring case 41 common guarantee can flick the position of spring 7, ensure that work is smooth and easy.
In general, flicking spring 7 described in, described port lid 1 and port lid circle 8 can be flicked angle be 10 °-20 °; Then relying on the effect of helical spring 53 that port lid 1 and port lid circle 8 are opened angle be 30 °-70 °, is then greater than 120 ° by operator's angle that opens it, is convenient to pass in and out.Two groups of universal ball ends 52, sleeve 54, helical spring 53, piston rod 55 and closing in chute 51 are set and improve the effect that this device upsprings automatically undoubtedly especially, and uniformly and stably active force is applied to port lid 1, reduce moving component wearing and tearing.Simultaneously flick spring 7 place at each and be provided with the stability that installing hole 31 and spring case 41 further improve device.
And the present invention can effectively prevent port lid stolen: port lid surface is without the need to arranging lift-pull handle or hole, and edge yet without the need to the reserved gap being convenient to pry open, when therefore port lid closes, it does not have origin of force, is not easy to be pried open to steal., after retaining mechanism being unlocked with key, by flicking spring, port lid being upspring automatically, not only substantially increasing theftproof performance also more time saving and energy saving during unlatching.Port lid and port lid circle are hinged, are also not easy to be stolen even if port lid is opened; Can also avoid occurring that the security incident problem in hole called in by personnel's vehicle.
