Abstract
The utility model particularly relates to a shock-absorption and muting inspection well cover for an inspection well. The shock-absorption and muting inspection well cover comprises a well cover and a well seat, wherein the edge of the well cover is mounted on an inner ring of the well seat; the inner ring is provided with a shock-absorption gasket. The shock-absorption and muting inspection well cover is characterized in that the inner edge of the inner ring of the well seat is provided with an upward convex bearing part; the inner ring is further provided with a shock-absorption gasket fixing groove; the bottom of the shock-absorption gasket is provided with a shock-absorption gasket bulge matched with the shock-absorption gasket fixing groove; the edge of the well cover is in contact with the shock-absorption gasket; a gap is formed between the bearing part and the well cover above the bearing part. The shock-absorption and muting inspection well cover has the advantages of good shock-absorption and muting effects and long service life. With the adoption of the shock-absorption and muting inspection well cover, the deformation amount of the shock-absorption gasket is controlled in the ultimate deformation amount; under the precondition of guaranteeing shock absorption and muting, the service life is greatly prolonged, the service life of the shock-absorption gasket is greatly prolonged and the service lives of the well cover and the well seat are also greatly prolonged.
Description
Technical field
The utility model is specifically related to a kind of quiet inspection well cover of damping that is applied to inspection shaft.
Background technology
When automobile high-speed passes through inspection well cover, under huge pressure-acting, well lid meeting and well seat bump, produce the noise of " bang ", noise not only disturbs residents, well lid and well seat bump, also can cause damage, reduction of service life, traditional structural approach is on the inner ring of well seat, to lay the damping washer of one deck rubber or silica gel, this structure has well solved the problem of noise, but when automobile passes through inspection well cover, whole pressure has all concentrated on damping washer, damping washer is often extruded distortion and surpasses its ultimate deformation amount, damping washer will follow the string very soon like this, do not have the quiet effect of damping.
Utility model content
The purpose of this utility model is the damping washer short defect in application life that solves the quiet inspection well cover of prior art damping, and a kind of quiet inspection well cover of damping of damping washer long service life is provided.。
The utility model is achieved by the following technical solution:
It is the quiet inspection well cover of a kind of damping, comprise well lid and well seat, the edge of well lid is arranged on the inner ring of well seat, inner ring is provided with damping washer, it is characterized in that the load receiving part that the inner ring inward flange setting of well seat raises up, be also provided with damping washer fixed groove on described inner ring, the bottom of described damping washer is provided with the damping washer projection of mating with damping washer groove, the edge of described well lid contacts with damping washer, between load receiving part and the well lid of top, is provided with gap.
When automobile process inspection well cover, under pressure, well lid moves down, because the edge of well lid contacts with damping washer, damping washer plays the quiet effect of damping, and well lid continues downwards, and the gap between load receiving part and well lid disappears, now well lid can not continue downwards, and damping washer can not be extruded over its ultimate deformation amount.
As a preferred version of the present utility model: the bottom of well lid is provided with the well lid groove corresponding with load receiving part position, is provided with gap between load receiving part and well lid groove.
As such scheme, well lid, without redesign, only need dig the groove that a circle mates with load receiving part in the bottom of common well lid.
As a preferred version of the present utility model: the edge of well lid is provided with the well lid projection of downward protrusion, is provided with gap between load receiving part and well lid.
The utlity model has that damping muting function is good, the advantage of long service life.Use the utility model, within the deflection of damping washer is controlled in its ultimate deformation amount, guaranteeing, under the quiet prerequisite of damping, greatly to have extended its application life, the life of damping washer, also makes the life-span of well lid and well seat greatly extend.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structure for amplifying schematic diagram of well seat in Fig. 1;
Fig. 3 is the structure for amplifying schematic diagram of damping washer in Fig. 1;
Fig. 4 is the structure for amplifying schematic diagram at well lid edge in Fig. 1;
Fig. 5 is the structural representation of the utility model embodiment 2.
As shown in FIG.: 1. well seat; 2. damping washer; 3. damping washer fixed groove; 4. well lid groove; 5. load receiving part; 6. well lid; 7. damping washer is protruding; 8. well lid is protruding.
The specific embodiment
Embodiment 1
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4: the inner ring inward flange of well seat 1 arranges load receiving part protruding upward, on inner ring, be also provided with damping washer fixed groove 3, damping washer 2 is arranged on inner ring by the damping washer projection 7 of bottom, the two ends of damping washer 2 lean against respectively the inner side, outer ring of well seat 1 and the inner side of load receiving part 5, certain distance is arranged at the bottom of the distance from bottom damping washer fixed groove 3 of described damping washer projection 7, the bottom of well lid 6 is provided with the well lid groove 4 corresponding with load receiving part 5 positions, the edge of well lid 6 contacts with damping washer 2, between load receiving part 5 and well lid groove 4, be provided with gap, the height of this gap is less than the ultimate deformation amount of damping washer 2.
When automobile process inspection well cover, under pressure, well lid 6 moves down, because the edge of well lid 6 contacts with damping washer 2, damping washer 2 plays the quiet effect of damping, and well lid 6 continues downwards, and the gap between load receiving part 5 and well lid groove 4 disappears, now well lid 6 can not continue downwards, and damping washer 2 can not be extruded over its ultimate deformation amount.
Embodiment 2
As shown in Figure 5: the edge of well lid is provided with well lid projection 8, well lid projection 8 contacts with damping washer 2, and load receiving part 5 is provided with gap before with well lid, and the height of this gap is less than the ultimate deformation amount of damping washer 2.Other are with embodiment 1.
Claims (3)
1. the quiet inspection well cover of damping, comprise well lid and well seat, the edge of well lid is arranged on the inner ring of well seat, inner ring is provided with damping washer, it is characterized in that the load receiving part that the inner ring inward flange setting of well seat raises up, be also provided with damping washer fixed groove on described inner ring, the bottom of described damping washer is provided with the damping washer projection of mating with damping washer groove, the edge of described well lid contacts with damping washer, between load receiving part and the well lid of top, is provided with gap.
