Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, for the utility model discloses a pre-buried formula fixing device's an embodiment schematic diagram, fixing device in this embodiment includes cavity steel pipe 1, 1 inside internal threads that are provided with of cavity steel pipe, with 2 one end of screw rod that the internal thread matches with 1 threaded connection of cavity steel pipe, the other end is connected with fastener 3, cavity steel pipe 1 buries ground and pours fixedly with ground on every side, fastener 3 compresses tightly equipment with the ground cooperation.

Because cavity steel pipe 1 buries ground and pours fixedly with ground on every side, consequently, the rigidity intensity requirement to former ground is low, still can guarantee the stable position of cavity steel pipe 1 in the ground, can not take place to rock, can also guarantee 2 backs in the screw in cavity steel pipe 1, the stability of 2 positions of screw, because screw 2 and 1 threaded connection of cavity steel pipe, consequently 2 atress of screw are big, it can compress tightly equipment with the ground cooperation to ensure the fastener 3 of 2 tip of screw, prevent that equipment from producing to rock and cause the damage to equipment in the course of the work. In order to ensure the stability of the connection between the screw rod 2 and the fastener 3, the screw rod 2 and the fastener 3 are connected by welding. Further, in order to guarantee that the distance between the fastening piece 3 and the ground is enough to clamp the equipment with any thickness, the upper edge of the hollow steel pipe 1 is flush with the ground, and at the moment, even if a fixing device is not used, the fixing device does not protrude out of the ground, so that the attractiveness of the ground cannot be influenced, the ground cannot be obstructed in use, and the foot cannot be stumbled. The adoption is at 2 one end connection fastener 3's of screw rod mode fixed equipment, on the one hand because the equipment foot is last not necessarily offered threaded hole, compresses tightly equipment through 3 cooperations of fastener and can be applicable to various different equipment, and on the other hand, the equipment product that fastener 3 can be fixed as required is changed to satisfy different demands. In this embodiment, the fastener 3 is the pressure strip 3a, and the pressure strip 3a can be various shapes, adopts circularly in this embodiment, adopts panel can guarantee that the contact surface with equipment is big, compresses tightly more stably to equipment. The stress of the fixing device can be changed by changing the size of the hollow steel pipe 1, the depth of the hollow steel pipe embedded into the ground, the size of the compression plate 3a and the size of the screw rod 2, so that the stress requirements of different devices can be met. In order to further ensure the fixation of the equipment, after the pressing plate 3a presses the equipment, holes can be punched on the pressing plate, and the pressing plate 3a and the equipment feet are locked through fastening bolts.
