The inner part of the metal joint is provided with a conical surface which is respectively matched with the conical surfaces of the two metal joints to tightly fix the two metal joints together. And the rubber sealing ring on the end face of the metal joint is compressed to prevent leakage;

preferably, the rubber hose end is provided with a metal fitting.

Preferably, the end face of the metal joint is provided with a sealing groove, and a sealing ring is arranged in the sealing groove. The metal joint is provided with a conical surface which is matched with the conical surface in the hoop.

Preferably, the clamp is of a two-half structure and is connected through four socket head cap screws. The screw is fully sunk in the hole provided in the clamp. The clamp is matched with the conical surfaces of the two metal joints through the inner conical surface of the clamp.

Preferably, the clamp has a compact structure, and the outer diameter of the clamp can be equal to or smaller than that of the rubber hoses at the two ends.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a rubber hose tip is provided with metal joint, and metal joint is through vulcanizing and rubber hose bonding together, and metal joint's terminal surface is provided with the seal groove, is provided with rubber seal in the seal groove. The two metal joints are tightly fixed together by a clamp. And the rubber sealing ring is compressed and deformed, so that the liquid in the rubber hose is prevented from leaking.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clear, fully described, and more clearly understood, embodiments of the present invention are described in further detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of some embodiments of the invention and that no limitation to the embodiments disclosed herein is intended or should be inferred by those skilled in the art that other embodiments may be devised without departing from the scope of the invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

For purposes of simplicity and explanation, the principles of the embodiments are described primarily by reference to examples. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art that the embodiments may be practiced without these specific details. In some instances, well-known methods and structures have not been described in detail so as not to unnecessarily obscure the embodiments. In addition, all embodiments may be used in combination with each other.

Referring to fig. 1 to 3, the present invention provides a technical solution: a crimp-facilitating rubber hose connection structure, the crimp-facilitating rubber hose structure comprising: rubber hose 1, metal joint 2, rubber seal 3, clamp 4, socket head cap screw 5

The rubber hose is composed of an inner rubber layer, a reinforcing layer and an outer cross layer, and a metal joint is arranged at the end part of the rubber hose. The metal joint is bonded with the rubber hose through vulcanization and can bear a certain stretching effect. The end part of the metal joint is provided with a sealing groove, and a rubber sealing ring is arranged in the sealing groove. When the rubber hose is connected, the two metal connectors are tightly fixed together by the clamping band. The metal joint is provided with a conical surface which is matched with the conical surface in the hoop. The clamp is of a two-half structure and is connected together by using four socket head cap screws. Wherein the screw is fully sunk in a hole provided in the clamping band. When the two halves of the structure are connected and fastened by the clamp, the sealing ring at the end part of the metal joint is compressed and deformed, and the liquid in the rubber hose is prevented from leaking.

Because the clamp is compact, the outer diameter of the clamp can be equal to or smaller than the outer diameter of the rubber hose. When a plurality of sections of rubber hoses are connected, the whole outer diameter does not have a bulge. Thus, it is convenient to crimp long rubber hoses on large crimping equipment, as shown in fig. 4. Meanwhile, the width of the clamping band is small, so that the bending of the rubber hose is not influenced, and the rubber hose has a small bending radius, such as the position of the clamping band shown in fig. 4. The rubber hose connecting structure convenient to curl enables the rubber hose to be connected and used for a long distance and is convenient to store.

Although the illustrative embodiments of the present application have been described above to facilitate the understanding of those skilled in the art to which the present application pertains, the present application is not limited to the scope of the embodiments, and it will be apparent to those of ordinary skill in the art that all applications that utilize the concepts of the present application are contemplated as being protected by the present application as long as the variations are within the spirit and scope of the application as defined and defined in the appended claims.
