The utility model content

The well lid that the utility model purpose is that a kind of well seat is provided and has this well seat when solving that vehicle is through well lid in the prior art, produces the technical problem of vibration and sound, well lid generation flop phenomenon and the breakage of well seat between well lid and the well seat.

Be to realize above-mentioned purpose, an aspect according to the utility model provides a kind of well seat, and this well seat comprises a up big and down small stepped hole, and stepped hole comprises a step surface, and the well seat also comprises a rubber buffer; Rubber buffer is arranged at step surface.

Further, rubber buffer adopts gluing mode to be fixedly set in step surface.

Further, rubber buffer is circular.

According to the utility model on the other hand, a kind of well lid is provided also, this well lid cooperates with above-mentioned well seat, and wherein, well lid comprises periphery; Periphery is wrapped in the rubber cushion cover.

Further, rubber cushion cover comprises first binding face of fitting with the inwall of periphery; Rubber cushion cover also comprises second binding face that is connected in first binding face and fits with the outer wall of periphery.

Further, well lid also comprises first end face; The week edge-perpendicular extension of cause first end face forms; Second binding face extends to first end face, and wraps up the junction of first end face and periphery.

Further, well lid is matched with the stepped hole of well seat, and wherein, the end wall of periphery compresses on the rubber buffer of step surface setting; Rubber cushion cover is replaced the inwall of the big nose end of stepped hole.

The utlity model has following beneficial effect:

Through the utility model, can reduce the vibration and the sound that produce between well lid and the well seat, and the flop phenomenon that has taken place when having avoided well lid to have vehicle to roll, prolonged the application life of well lid and well seat simultaneously.

Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.

Description of drawings

The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:

Fig. 1 is the structural representation that well lid cooperates with the well seat in the prior art;

Fig. 2 is the structural representation of the well seat of the utility model preferred embodiment;

Fig. 3 is the structural representation of the well lid of the utility model preferred embodiment; And

Fig. 4 is the structural representation that the well lid of the utility model preferred embodiment cooperates with the well seat.

The specific embodiment

Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Referring to Fig. 2, well seat 1 is cylindric, and it comprises a up big and down small stepped hole 11.Stepped hole 11 comprises a step surface 111.

Well seat 1 is provided with the rubber buffer 13 with step surface 111 couplings.When vehicle rolled well lid 3, rubber buffer 13 can reduce the impact force of 3 pairs of well seats 1 of well lid.Rubber buffer 13 is circular, and its actual size can be made according to the real size of the step surface 111 of well seat 1.

Rubber buffer 13 is processed for elastomeric material, preferably adopts the rubber material, and it adopts mold pressing to make.Rubber buffer 13 can adopt gluing mode to be fixedly set in the step surface 111 of well seat 1.

See also Fig. 3, the periphery 33 of well lid 3 for having the cylindric of first end face 31 and extending by the edge-perpendicular of first end face 31.The periphery 33 of well lid 3 is enclosed with a rubber cushion cover 35.

Rubber cushion cover 35 comprises first binding face 351 of fitting with the inwall of periphery 33.Rubber cushion cover 35 also includes second binding face 353 that is connected in first binding face 351 and fits with the outer wall of periphery 33.

For preventing that rubber cushion cover 35 from coming off from periphery 33, second binding face 353 of rubber cushion cover 35 extends to first end face 31 of well lid 3, and the junction of first end face 31 with periphery 33 wrapped up.

Rubber cushion cover 35 is processed for elastomeric material, preferably adopts the rubber material, and it adopts mold pressing to make.The concrete grammar that rubber cushion cover 35 is arranged at periphery 33 is: periphery 33 is placed in the rubber cushion cover 35, and flexible because of rubber cushion cover 35, therefore, rubber cushion cover 35 can wrap up periphery 33 tightly.

Please combine referring to Fig. 4, well lid 3 is placed in the stepped hole 11 of well seat 1.Be specially: well lid 3 is covered on the stepped hole 11 of well seat 1.At this moment, periphery 33 matches with the macropore on stepped hole 11 tops of well seat 1, and periphery 33 compress the rubber buffer 13 on the step surface 111 with first end face, 31 relative end walls.The rubber cushion cover 35 of periphery 33 and the inwall mutual extrusion of the big nose end on stepped hole 11 tops of well seat 1 are so that the combination between well lid 3 and the well seat 1 is tightr.That is: flop phenomenon takes place for closely cooperating to prevent well lid 3 in well lid 3 and well seat 1 when vehicle rolls well lid 3 edges.And the rubber buffer 13 that rubber cushion cover 35 that the periphery 33 of well lid 3 is nested with and well seat 1 are provided with can be good at absorbing from the impact force of vehicle to well lid 3.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
