Description

Firmer quick-connecting hose clamp

Technical Field

The utility model relates to a clamp especially relates to a throat hoop that structure is more firm after locking, quick joint and release.

Background

The clamp is used as a connecting piece, has wide application and great effect in the engineering field or the living field, is a connecting device for connecting pipe fittings with grooves, valves and pipeline fittings, and is used for tightly connecting quick connectors. The hose clamp is one of the hose clamps, has very wide application in various countries, and is divided into an English hose clamp, an American hose clamp and a German hose clamp, and the functions of the English hose clamp, the American hose clamp and the German hose clamp are different. The structure of the throat hoop can be divided into an open throat hoop, a flip throat hoop and the like.

The utility model mainly relates to a throat hoop of institutional advancement, the design that there is the structure in the throat hoop on the market now is bad, leads to the uneven condition that leads to locking part deformation and the strap to collapse easily of throat hoop locking part atress after the joint to make the effect of throat hoop become invalid.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems that after the hose clamp is locked in the prior market, the locking part is easy to deform and the strap is easy to collapse in the prior art, a firmer and quick-connection hose clamp is provided.

The technical scheme of the utility model a firmer formula larynx hoop that connects soon, including locking part and strap, locking part include outer support, inner support and worm, the outer support be connected with the strap, the worm establish on the inner support, the worm be connected with the worm wheel hole on the strap, the inner support be connected with the outer support, the outer support on be equipped with the breach face, the breach face on be equipped with first breach, the inner support on be equipped with the hangers, the hangers embedding in first breach; the inner support has a first state which is convenient for opening the connection of the inserted strap and a second state which is matched with the outer support for locking, and in the second state, the hanging lugs are contacted with the notch surfaces, so that the inner support applies pressure to the outer support. The design that the hanging lug is embedded into the first gap of the outer support ensures that the inner support and the outer support still can ensure stable structure and are not easy to deform under the condition that the strap is clamped tightly to generate larger tension because the tension of the strap drives the worm and the worm drives the inner support and the outer support, the inner support applies pressure to the outer support, and the hanging lug enables the contact surface of the outer support to be larger. And the design that the hangers are embedded into the gaps can make the whole strap look smaller.

The notch surface comprises a horizontal surface and a vertical surface, and the horizontal surface and the vertical surface form an L-shaped notch surface. The hanging lug comprises a horizontal part and a vertical part, the horizontal part and the vertical part form an L-shaped hanging lug, the vertical part comprises a vertical surface, and the vertical surface of the vertical part of the hanging lug is in contact with the vertical surface of the gap surface, so that the inner support applies pressure to the outer support.

The larger the contact area is, the smaller the pressure intensity of the inner support to the outer support is under the condition that the inner support applies the same pressure to the outer support, so that the integral structure is firmer.

The inner support comprises a first vertical plate, a second vertical plate and an upper cover, wherein a transverse plate is arranged on the inner side of the outer support, the transverse plate is arranged on the left side and the right side of the outer support, second notches are formed in the left side and the right side of the second vertical plate, the transverse plate partially penetrates through the second notches, and the second vertical plate is limited below the transverse plate in the second state of the inner support. The transverse plate can ensure that the inner support frame is not lifted after the hose clamp is locked, and the inner support frame can be lifted only after the hose clamp is out of the locking state.

The transverse plate and the outer bracket are integrally formed. The integrally formed structure can save production cost and also ensure that the structure of the outer bracket is firmer.

The clamp is characterized in that one end of the outer support base plate in the stress direction of the outer support is provided with a protruding clamping block, the clamp belt is provided with a clamping port, the clamping block is inserted into the clamping port to form a clamping structure, and the other end of the support base plate is welded with the clamp belt body. The strap body is provided with a concave part, and the outer support bottom plate is embedded into the concave part. After the throat hoop is in a locked state, the tension of the strap acts on the outer support in one direction, the protruding clamping blocks on the outer support are in one-way fit with the clamping interfaces of the strap, and the other end of the strap is connected with the outer support through the spot welding technology, so that the production time and cost can be saved, and the production efficiency is improved. The strap body is provided with a bending part, so that a concave part is formed on the strap body, and the throat hoop is small and exquisite integrally due to the fact that the outer support is embedded into the concave part.

The inner support comprises a first vertical plate, a second vertical plate and an upper cover, sliding groove holes are formed in the left side and the right side of the outer support, the first vertical plate penetrates through the sliding groove holes and can move back and forth in the sliding groove holes, hanging angles are arranged on two sides of the first vertical plate, and the outer support is arranged on the inner side of the hanging angles to enable the inner support to be hinged with the outer support. The hanging angles are arranged on two sides of the first vertical plate of the inner support, so that the left-right movement range between the inner support and the outer support can be limited, and the inner support can only be turned upwards, covered downwards or moved forwards and backwards on the outer support.

The utility model has the advantages that: 1. the clamp has larger fastening force in a fastening state. 2. The inner support and the outer support are not easy to deform in a fastening state. 3. The screw thread of the screw rod of the hose clamp and the worm hole of the clamping band are enlarged, so that the hose clamp is not easy to break. 4. The inner bracket can be turned up and inserted into the strap for quick clamping. 5. The whole hose clamp looks more compact and delicate.
