Said joint is located at the sidepiece of said matrix, and at least one said blind-hole type reinforced structure is near the sidepiece of this matrix.
The another kind of scheme of the utility model is.
A kind of screw connecting base comprises matrix and is located at the joint on the matrix, on joint, is provided with attachment hole; Between matrix and joint, be provided with the passing hole type reinforced structure, joint is connected on the matrix through this passing hole type reinforced structure, and the passing hole type reinforced structure comprises sidewall, surrounds the hole in the sidewall.
Its further improvement project is.
Said passing hole type reinforced structure is at least two, each passing hole type reinforced structure near, and its through hole towards consistent and form cellular structure.
Said joint is circular tower shape, the sidewall rounding off of the said passing hole type reinforced structure of its two side direction along the axial projection of said attachment hole.
Said joint is located at the sidepiece of said matrix, and at least one said passing hole type reinforced structure is near the sidepiece of this matrix.
Advantage or principle in the face of the utility model describes down:
1, owing between matrix and joint, be provided with blind-hole type structure or passing hole type structure, promptly between matrix and connecting base, form at least one blind hole or through hole, the screw connecting base is receiving when impacting or shaking and can effectively cushion; Simultaneously, be connected through a plurality of sidewalls between matrix and the connecting base, effectively reduced stress and concentrated; And the design of end wall; Once more stress is concentrated to drop to minimumly, when stress was excessive, end wall can delay breaking of sidewall;
2, adopt cellular structure; Make the stress distribution at blind-hole type reinforced structure or passing hole type reinforced structure place more even; Reduced the probability that single blind hole or through hole break, and the outside of each said blind-hole type reinforced structure end wall is concordant, can avoids forming structural mutation and causing stress to concentrate at end wall;
3, joint is circular tower shape, and with blind-hole type reinforced structure rounding off, avoid structural mutation occurring between joint and blind-hole type reinforced structure or the blind-hole type reinforced structure;
4, under the situation of accepting bump; The sidepiece of matrix is collided more easily and is destroyed; And in the connection of mechanical structure, joint is also set up the side locations in matrix, and at least one blind-hole type reinforced structure or blind-hole type reinforced structure are near the sidepiece of matrix; Can avoid when colliding, directly joint being caused damage, improve the working life of screw connecting base.

Embodiment
Embodiment in the face of the utility model is elaborated down.
Embodiment is just like Fig. 2, shown in Figure 3, and a kind of screw connecting base comprises matrix 1 and is located at the joint 2 on the matrix 1, on joint 2, is provided with attachment hole 3; Between matrix 1 and joint 2, be provided with blind-hole type reinforced structure 4, joint 2 is connected on the matrix 1 through this blind-hole type reinforced structure 4, and blind-hole type reinforced structure 4 comprises sidewall 5 and end wall 6, surrounds the hole in the sidewall 5, and end wall 6 seals an end in hole and the formation blind hole.
Wherein, said blind-hole type reinforced structure 4 is three, each blind-hole type reinforced structure 4 near, and its blind hole towards consistent and form cellular structure, the outside of each said blind-hole type reinforced structure 4 end wall 6 is concordant.Said joint 2 is circular tower shape, sidewall 5 rounding ofves of the said blind-hole type reinforced structure 4 of its two side direction along said attachment hole 3 axial projections.
