The high-reliability flange clamp further comprises a locking nut, and the locking nut is matched with the jackscrew through threads and leans against the lug seat.

According to the high-reliability flange clamp, saw-shaped teeth corresponding to the flange are arranged at one end, far away from the locking column, of the U-shaped beam.

According to the high-reliability flange clamp, the locking column penetrates through the rectangular hole in the straight arm at one end of the U-shaped beam, and the pin shaft penetrates through the shaft hole in the locking column and is inserted into the pin hole in the side wall of the rectangular hole.

According to the high-reliability flange clamp, the end face of the front end of the jackscrew is a spherical surface, and the contact surface of the locking column and the front end of the jackscrew is a conical surface.

In the high-reliability flange fixture, the end face of one end, which is propped against the flange, of the locking column is a spherical surface.

The utility model discloses utilize the jackscrew to provide the clamp force, utilize the lever mechanism that locking post and round pin axle constitute to enlarge clamping-force, can provide enough big clamp force for the flange. Compare with traditional flange anchor clamps, the utility model discloses simple structure, the dependable performance can prevent effectively that the flange from droing from anchor clamps, guarantees going on smoothly of production.

Detailed Description

The utility model provides an anti-drop's semipermanent flange anchor clamps, this kind of anchor clamps can prevent that fixed flange from taking place relative movement or coming off, guarantee going on smoothly of production.

Referring to fig. 1, 2 and 3, the present invention mainly comprises a jackscrew 1, a lock nut 3, a locking column 4, a pin 5 and a U-shaped beam 7. Wherein, the U-shaped beam 7 is provided with a lug seat 2, a threaded hole 8, a pin hole 10, a rectangular hole 9, a saw-shaped tooth 11 and other structures; the jackscrew 1 is installed on the lug seat 2 of the U-shaped beam 7 through threads; the lock nut 3 is arranged on the thread of the jackscrew 1 and rubs against the side surface of the lug seat 2 to prevent the jackscrew 1 from loosening; the locking column 4 is arranged in a rectangular hole 9 of the U-shaped beam 7, a shaft hole 13 of the locking column 4 is aligned with a pin hole 10 of the U-shaped beam 7 through a pin shaft 5, and the locking column 4 can rotate in the rectangular hole 9 by taking the pin shaft 5 as a shaft; the pin shaft 5 is arranged in a pin hole 10 of the U-shaped beam 7 and used for installing the locking column 4.

As shown in fig. 1 and 2, the U-shaped beam 7 is designed with 30 ° saw-shaped teeth 11, which are disposed vertically inward to prevent the flange 6 from falling off.

As can be seen from fig. 1 and 3, the end surface of the locking column 4 at the end contacting the flange 6 is designed as a spherical surface, and the spherical surface contacts the surface of the flange 6 to prevent the spherical surface from damaging the surface of the flange during relative sliding.

As can be seen from fig. 1, the end face of the front end of the jackscrew 1 is also designed as a spherical surface, and the spherical surface is matched with the conical surface on the locking column 4, so that the locking column 4 can move flexibly.
