In order to achieve the above purpose, the present utility model is realized by the following technical scheme: the utility model provides a turn to buffer stop, includes the buffer stop main part, the circular slot that link up has been seted up to the surface of buffer stop main part, the inboard end in circular slot is provided with first strengthening rib and second strengthening rib, the second strengthening rib is located the below of first strengthening rib, first strengthening rib all is circumference array setting with the second strengthening rib.

As a further preferable mode of the technical scheme, the buffer stop main body is formed by injection molding of PA66-GF30, and comprises an upper half and a lower half, wherein the upper half is positioned at the bottom of the lower half, and the upper half and the lower half are of an integrated structure.

As a further preferable mode of the technical scheme, the surfaces of the upper half part and the lower half part are provided with a first groove and a second groove which are communicated, and the first groove and the second groove are combined into a round groove.

As the further preference of this technical scheme, first strengthening rib is provided with eight, and eight first strengthening ribs are circumference array distribution at first recess inner wall, eight the up end and the top parallel and level of first strengthening rib half.

As the further preference of this technical scheme, first strengthening rib is provided with nine, and nine first strengthening ribs are circumference array distribution at second recess inner wall, nine the lower terminal surface of first strengthening rib and the bottom parallel and level of lower half.

Compared with the prior art, the method has the following beneficial effects:

the PA66-GF30 material with high impact resistance, high strength and better wear resistance is subjected to injection molding, so that the product is more stable, and the impact resistance, strength and friction resistance are improved; the eight reinforcing rib structures are flush with the upper end face, so that the strength of the product is higher, and the pressure requirement during use is met; nine reinforcing ribs are flush with the lower end face, so that the product is more firmly assembled and is more stable in operation.
