Detailed Description

As shown in fig. 1-6, an abnormal sound prevention inspection well device comprises a well lid 1 and a well ring 2, wherein the well lid 1 is provided with a hinged ear seat 101, the outer edge of the well ring 2 is provided with a convex groove body 202, the hinged ear seat 101 is hinged with the convex groove body 202, a flexible bottom gasket 4 and a side gasket 5 are further arranged, a plurality of first clamping parts 401 are arranged on the outer wall of the bottom gasket 4 along the circumferential direction, a plurality of second clamping parts 501 are arranged on the outer wall of the side gasket 5 along the circumferential direction, a sink 203 is arranged at the upper end of the well ring 2, the bottom gasket 4 is arranged at the bottom end of the sink 203, the side gasket 5 is arranged on the inner wall of the sink 203, a plurality of clamping grooves 201 are arranged on the inner wall of the sink 203 along the circumferential direction, and each first clamping part 401 and each second clamping part 501 are clamped in each clamping groove 201.

The bottom gasket 4 is thinner in height and thicker in thickness, the side gasket 5 is thicker in height and thinner in thickness, the first clamping portion 401 and the second clamping portion 501 share one clamping groove 201, and the side gasket 5 can press the bottom gasket 4.

When the vehicle rolls the well lid 1, the tire rotates, and a friction force to the well lid 1 exists in the tangential direction of rotation, so that the well lid 1 is subjected to transverse force besides downward gravity, and therefore the bottom gasket 4 is used for being padded between the well lid 1 and the bottom surface of the sinking groove 203, the side gasket 5 is used for covering the inner wall of the sinking groove 203, impact forces in two directions are reduced, the well lid 1 and the well ring 2 are prevented from being directly collided, and the silencing effect is achieved.

The material upper well cover 1 and the well ring 2 can be made of rubber, silica gel, nylon, polyurethane and the like, the hardness is in a range of 76-95 IRHD, the tensile strength is not lower than 9 MPa, the elongation at break is not lower than 100%, and the material upper well cover is corrosion-resistant and not easy to biodegrade.

The dovetail groove type design is adopted on the inner wall of the sinking groove 203, and the bottom gasket 4 and the side gasket 5 are clamped in the clamping groove 201 through dovetail type bulges, namely the first clamping part 401 and the second clamping part 501, so that the well lid 1 is prevented from being loosened and blocked to be normally closed, and the well lid is also prevented from being lost due to falling out during transportation or use.

The first engagement portion 401 and the second engagement portion 501, and the card slot 201 may be T-shaped, Ω -shaped, or the like.

In the preferred scheme, a through hole 102 is formed in the hinge lug 101, a flexible spacer bush 6 is arranged in the through hole 102, a strip-shaped hole 601 is formed in the spacer bush 6, a hinge bolt 3 is further arranged, the hinge lug 101 and the convex groove 202 are hinged through the hinge bolt 3, and the hinge bolt 3 is inserted into the strip-shaped hole 601.

Because the bottom gasket 4 and the side gasket 5 are made of flexible materials, when one end of the well lid 1 far away from the hinged ear seat 101 is pressed, the hinged bolt 3 can be subjected to larger transverse shearing force if a traditional hinged mode is directly adopted, and because the hinged bolt 3 is thinner and even directly pressed and broken, the gap between the through hole 102 and the hinged bolt 3 is filled by the spacer 6 made of the same materials as the bottom gasket 4 and the side gasket 5, a groove body moving in the up-down direction is reserved, when the well lid 1 is pressed, all directions of the well lid 1 are evenly lowered, the hinged bolt 3 is in an active state and can not be subjected to larger shearing force, and the well lid 1 used at ordinary times can be normally turned over.

In the preferred scheme, the side washer 5 is provided with a convex part 502, the convex part 502 is clamped on the inner wall of the convex groove body 202, the convex part 502 is provided with a lower opening avoidance groove 503, and the hinge bolt 3 passes through the avoidance groove 503.

The inner wall of the convex groove body 202 is also provided with a clamping groove 201, the outer wall of the convex part 502 is also provided with a second clamping part 501, and the convex part 502 wraps the hinge lug 101 at the convex groove body 202 to prevent the hinge lug 101 from directly colliding with the convex groove body 202.

In a preferred embodiment, the upper end surface of the side washer 5 is not lower than the upper end surface of the side wall of the sink 203.

If the upper cross section of the side washer 5 is lower than the upper end surface of the side wall of the sink 203 after being mounted, a groove is formed therein, and dust is easily accumulated, so that it is required to be higher than the upper end surface of the side wall of the sink 203.

The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
