For prevent that well lid from rotating arbitrarily on walling crib, the well lid bottom surface is provided with 2 locks, correspondingly, is provided with the boss of horizontal direction at walling crib snap ring two places, and during installation, 2 locks of well lid bottom surface are stuck in the homonymy of boss.
In well lid edge, be provided with a lockpin hole, correspondingly, boss plane, a place increases a tray on the walling crib snap ring, comes off to prevent lock pin, just well lid and walling crib is locked together behind the lock pin of packing into.
Be provided with the anti-boss that reverses on one side at walling crib snap ring breach, can only can not be rotated counterclockwise clockwise when well lid is installed.
The utlity model has advantage simple in structure, antitheft, anti-jump dependable performance.
The utility model is done further auspicious stating below in conjunction with accompanying drawing.
Fig. 1 is the sectional view of the utility model well lid part
Fig. 2 is the back side vertical view of the utility model well lid part
Fig. 3 is the vertical view of the utility model walling crib part
Fig. 4 is the utility model walling crib, lid assembly relation schematic diagram
Shown in Figure 2 as Fig. 1, well lid bottom margin place is arranged with 4 claws (1), on the snap ring that is stuck in walling crib.Be provided with 2 locks (2) that prevent that well lid from rotating arbitrarily at well lid bottom margin place.In addition, in well lid edge, be provided with a lockpin hole (3).For improving the intensity of load of well lid, be provided with intersecting parallels reinforcing rib (4) at the well lid back side.For ease of well lid rotation breakdown, on well lid, also be arranged with lancet hole (5).
As shown in Figure 3, walling crib is provided with snap ring (6), and snap ring (6) is gone up quartering position and had 4 breach (7), and claw can place the bottom of snap ring by breach.The walling crib snap ring is provided with the boss (8) of horizontal direction, and 2 locks of well lid bottom surface are stuck in the homonymy of boss, rotates arbitrarily on walling crib to prevent well lid.Boss plane, a place increases a tray (9) on snap ring, and lock pin can not come off behind the lock pin of packing into, and well lid can not reverse breakdown simultaneously.Be provided with the anti-boss (10) that reverses on one side at walling crib snap ring breach.
As shown in Figure 4, the assembling process of the utility model cover for manhole is as follows: with the breach (7) on the aligning walling crib snap rings of four claws (1) on the well lid (6), put down well lid, mentioning well lid slightly with lancet turns clockwise, when lock (2) is positioned at the left side of boss (8) simultaneously, put steady well lid, well lid lock this moment (2) is stuck in the homonymy of walling crib boss (8), do not mentioning slightly under the situation of well lid, well lid promptly can not also just change and can not reverse.At this moment the lockpin hole of well lid edge (3) is just in time aimed at tray (9), lock pin is squeezed in the lockpin hole just the well lid walling crib has been locked together.
During the dismounting cover for manhole, well lid can be mentioned slightly, turning clockwise makes lock pin leave saddle, destroys lock pin, is rotated counterclockwise well lid to initial position, mentions well lid with lancet and breaks away from walling crib.
