In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of column of novel high rigidity, comprise mounting seat and column body, described mounting seat and described column body removably connect in the side, the cross section of described column body is trapezoidal, and the centre is hollow structure, forms Zuo Qiang and You Qiang respectively, the outside of described left wall and described right wall is respectively arranged with at least one meter type rib, and described rice type rib intersects at annulus.
In preferred embodiment of the utility model, the quantity of described rice type rib is 2, be respectively meter type rib and rice type rib, described rice type rib and described rice type rib upper and lower settings, and the center of described rice type rib and described rice type rib lengthwise position lays respectively at the trisection point of described left wall and described right wall.
In preferred embodiment of the utility model, the rib of the rib of described rice type rib and described rice type rib is orthogonal and intersect at the back wall, and the rib of the rib of described rice type rib and described rice type rib is orthogonal and intersect at front wall.
In preferred embodiment of the utility model, the height of each rib of described rice type rib be between described left wall and the described right wall distance 1/4.
In preferred embodiment of the utility model, the lateral attitude of described rice type rib and the center of gravity of described column coincide.
In preferred embodiment of the utility model, described column body bottom also is provided with feed screw nut's seat, and the center of gravity of described feed screw nut's seat and the center of gravity of described column coincide.
The utility model has solved the defective that exists in the background technology, the column of the novel high rigidity that the utility model disclosed, comprise mounting seat and column body, described mounting seat and described column body removably connect in the side, the cross section of described column body is trapezoidal, and the centre is hollow structure, forms Zuo Qiang and You Qiang respectively, the outside of described left wall and described right wall is respectively arranged with at least one meter type rib, and described rice type rib intersects at annulus.The column of the novel high rigidity that the utility model disclosed is compared with traditional column and is had the following advantages:
1. because the outer setting of the left and right sides of the present utility model wall has a meter type rib, both strengthened the rigidity of column, the heat that helps accumulating in column inside again scatters and disappears, and thermal diffusivity is good.
2. because the lengthwise position of rice of the present utility model type rib is arranged at the trisection point of left and right wall respectively, and diagonal ribs is orthogonal and intersect with front-back wall, and through finite element analysis, the rigidity of column is high.
3. because lateral attitude and the column center of gravity of rice of the present utility model type rib coincide, and coincide with the center of gravity of feed screw nut's seat, in the column fast moving, when being hit power, be out of shape for a short time, it is steady to move.
4. the rigidity height is in light weight, and movement inertia is little.
