It is provided with mutually matched locking mechanism, the locking mechanism is for well lid closely to be connect with retainer ring.
By using above-mentioned technical proposal, buffer layer is set, therefore when well lid is ground by vehicle between well lid and retainer ring
When pressure or pedestrian trample, well lid directly will not directly collide with retainer ring, therefore will not issue noise and reach
Mute effect.And well lid is linked together with retainer ring by locking mechanism, can well lid be connect with retainer ring
It is even closer, be more less likely to occur relative movement and collision.
The utility model is further arranged to: the buffer layer is the buffer layer of rubber material.
By using above-mentioned technical proposal, the buffer layer of rubber material plays the role of buffering, while by well lid and support
Ring separates, and prevents retainer ring and well lid from colliding and issues noise.
The utility model is further arranged to: the locking mechanism includes the screw hole being arranged on supporting table, further includes setting
Set the through-hole corresponding with lower screw hole on well lid, be provided with locking bolt in through-hole, the head of locking bolt in through-hole with basement
Well rotation connection, locking bolt is coaxial with through-hole and can rotate around the axis of through-hole, and one end of locking bolt passes through buffering
Layer is threadedly coupled with screw hole.
By using above-mentioned technical proposal, the head by turning locking bolt can twist locking bolt from screw hole
Out, so as to well lid to be removed to replacement from retainer ring.
The utility model is further arranged to: ball bearing coaxial with the through hole, the head of locking bolt are fixed in through-hole
Portion is fixedly connected with the inner surface of the inner ring of ball bearing.
By using above-mentioned technical proposal, realizes locking bolt and well lid forms rotation connection relationship.
The utility model is further arranged to: being additionally provided with pilot hole on supporting table, is fixed on well lid and matches with pilot hole
The guiding axis of conjunction.
By using above-mentioned technical proposal, guiding axis is set and pilot hole cooperates, when locking bolt is back-outed from screw hole
Inspection well cover can also stablize rising, to easily remove inspection shaft from retainer ring.
The utility model is further arranged to: the threaded upper ends of the through-hole are connected with guard member.
By using above-mentioned technical proposal, guard member can enter in through-hole to avoid dust, and back-outing guard member can facilitate
Locking bolt is turned.
In conclusion the utility model has the following beneficial effects:
1, well lid by vehicle roll either pedestrian trample when, well lid because by buffer layer cladding without directly with
Retainer ring directly collides with, thus will not issue noise achieved the effect that it is mute；
2, locking bolt and well lid are rotatablely connected, and well lid and Support tray can be securely attached to together by locking bolt,
And the head by turning locking bolt can back-out locking bolt from screw hole, so as to which well lid is taken from retainer ring
Lower replacement.

Specific embodiment
The utility model is described further referring to attached drawing.
Present embodiment discloses a kind of mute well lids, as shown in Figure 1, including the retainer ring 1 positioned at inspection shaft borehole wall upper end, hold
Upper end in filler ring 1 is provided with circular supporting table 2, and circular well lid 3 is placed on supporting table 2, well lid 3 and retainer ring 1
The buffer layer 4 of rubber material is coated on the side of contact and one side towards borehole wall bottom end.On well lid 3 and retainer ring 1
It is additionally provided with mutually matched locking mechanism, locking mechanism is for well lid 3 closely to be connect with retainer ring 1.
As shown in Figure 1, 2, locking mechanism includes the screw hole being provided on supporting table 25, and screw hole 5 is coaxially set with well lid 3
It sets.Locking mechanism further includes one and is provided on well lid 3 through-hole 6 corresponding with lower screw hole 5, is fixed in through-hole 6 same with through-hole 6
The inner surface of the ball bearing 7 of axis, the inner ring 8 on the head 12 and ball bearing 7 of locking bolt is fixedly connected.Locking bolt and logical
Hole 6 is coaxial and can rotate around the axis of through-hole 6, and one end of locking bolt passes through buffer layer 4 and is threadedly coupled with screw hole 5.
In addition, being additionally provided with pilot hole 9 on supporting table 2, pilot hole 9 and screw hole 5 are in the same diametrical direction of well lid 3
Both ends are fixed with the guiding axis 10 cooperated with pilot hole 9 on well lid 3.
Because of cushion rubber layer 4 between well lid 3 and retainer ring 1, when well lid 3 is rolled either pedestrian by vehicle
When trampling, well lid 3 directly will not directly collide with retainer ring 1, therefore will not issue the effect that noise has reached mute
Fruit.
