Description

double-hoop heavy type hoop

Technical Field

The utility model relates to a fastener machinery technical field, concretely relates to kinds of heavy clamps of double hoop area.

Background

The clamp is connecting devices for connecting a pipe fitting with a groove, a valve and a pipeline fitting, and is used for tightening the quick connector, and common two connectors are provided with gaskets, rubber, silica gel and tetrafluoro.

In the existing clamp, the strap is of a single-layer structure, the bearing capacity of the strap is relatively weak, and the clamp is easily damaged when large internal tension is met, so that the leakage phenomenon occurs at the joint of the pipeline.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide kinds of heavy clamps of double hoop area, it not only has great power of cramping, and the atress is even moreover, has great holding power, is difficult for impairedly.

The utility model discloses the above-mentioned technical problem that will solve realizes through following technical scheme:

heavy clamp of two hoop area, it includes interior strap, outer strap and the seat of cramping, interior strap and outer strap have open-ended drum structure for the side, interior strap cover is in outer strap, and staggers each other with the opening of outer strap in the opening of interior strap, the seat of cramping overlaps in outer strap periphery to cramp through screw rod and nut, interior strap periphery be provided with convex closure, the outer strap in the week correspond the position have with the convex closure assorted shrinkage pool of interior strap, the shrinkage pool form new convex closure in outer strap periphery, the seat of cramping is interior to correspond the position and have the convex closure assorted shrinkage pool with outer strap, interior strap, outer strap and the seat of cramping are joined in marriage each other through convex closure and shrinkage pool and are carried out the chucking.

Preferably, the tightening seat is of a U-shaped arc structure, two ends of the tightening seat are respectively provided with a convex locking head, the locking heads at two ends are aligned in parallel, a through hole is formed in each locking head, and the screw rod penetrates through the through hole and is locked through the nut. The inner clamping band and the outer clamping band of the clamping base are clamped or loosened through the elastic nuts.

Preferably, the through hole is of a square structure, and the peripheral shape of the section below the nut of the screw is of a square structure matched with the through hole.

Preferably, the inner diameter of the outer clamping band is matched with the outer diameter of the inner clamping band, and the outer diameter of the outer clamping band is matched with the inner diameter of the clamping seat. This structural design scheme makes interior strap and outer strap, outer strap and the tight seat of cramping closely laminate, and even atress, bearing capacity are stronger.

Preferably, two of the clamping seats are used and are respectively positioned at two ends of the periphery of the outer clamping band. This structural design makes the outer power of cramping that receives stronger, and makes the even atress in both ends, and the effect of cramping is more excellent.

Preferably, the outer and inner bands are made of elastic metal alloy material. This design ensures that the outer and inner bands can be tightened or loosened.

Adopt the beneficial effect: adopt behind the structure, owing to be provided with interior strap and outer strap dual structure in the seat of cramping, closely laminate between the three, the atress is even, make the clamp whole have great bearing capacity, difficult impaired, the seat of cramping adopts two simultaneously, and be located the periphery both ends of outer strap respectively, provide great cramping force for inside, make the even atress in outer strap both ends, it is more excellent to cramp the effect, go into steps, interior strap, outer strap and the seat of cramping are through the mutual chucking of cooperation structure of protruding package and shrinkage pool, prevent the skew rotation of appearing, it is firm to make cramp, difficult not hard up.
