Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Embodiment
A kind of anchor formula foundation bolt, as shown in figure 1, including the bolt first 1 of circle, the upper end uniform intervals of bolt first 1 are provided with
The double wedge 2 of at least two strips, columnar key 3 is connected with below bolt first 1, the top of key 3 is arranged with nut 4,
Two symmetrical openings grooves 5 are offered in the side wall of the key 3 of the lower section of nut 4, open slot 5 is the strip of longitudinal direction, and two are open
Rotating shaft 6 is connected between the side wall of key 3 between groove 5, rotating shaft 6 is mutually hung down with the plane where the longitudinal centre line of two open slots 5
Directly, Internal baffle 7 is provided with the internal cavity of columnar key 3, axis hole is provided with the center of Internal baffle 7, rotating shaft 6 passes through axle
Hole, draw ring 8 is respectively arranged with the right side of the left side and lower end of the upper end of Internal baffle 7, is distinguished on Internal baffle 7 positioned at the both sides of axis hole
A positioning hole 9 is provided with, two keyholes are provided with the side wall of key 3, pilot pin 10, Internal baffle have been respectively protruding into keyhole
7 by rotating shaft 6 when being rotated to lateral attitude, and the position of its positioning hole 9 is corresponding with the position difference of pilot pin 10.
It can be seen that the anchor formula foundation bolt of the present embodiment, non-through cellular type keyhole was both can be used for, the energy of double wedge 2 on its bolt first 1
