Abstract

The utility model discloses a flexible pipe, which consists of a plurality of joints movably connected, wherein each joint comprises: a convex edge, a concave edge, and a retainer ring; the convex edge and the concave edge are formed by machining in an integrated machine, the outer diameter of the convex edge is smaller than the inner diameter of the concave edge, and the retainer ring is welded on the concave edge. The flexible pipe formed by the metal joints can bear high-strength bending force, and the protection and the guiding of the cable pipeline detection equipment are realized.

Description

Flexible pipe

Technical Field

The utility model relates to the field of hoses, in particular to a flexible pipe.

Background

When the online detection of the water pipeline is carried out, the transmission cable of the cable detection equipment can be clamped on the edge angle of the three-way valve at the throwing-in position frequently. This not only affects the transmission cable communications, but also causes severe wear to the cable itself.

In order to solve the above problems, some plastic hoses commonly available on the market are generally used as wear-resistant buffers, but they have the common disadvantage that when the transmission cable is subjected to a large pulling force, the plastic pipes are crushed, thereby affecting the normal detection task.

SUMMERY OF THE UTILITY MODEL

The utility model provides a flexible pipe consisting of a plurality of metal joints, which can bear high-strength bending force and protect and guide cables of cable pipeline detection equipment, and is described in detail as follows:

a flexible tube comprised of a plurality of articulately connected joints, the joints comprising: a convex edge, a concave edge, and a retainer ring;

the convex edge and the concave edge are formed by machining in an integrated machine, the outer diameter of the convex edge is smaller than the inner diameter of the concave edge, and the retainer ring is welded on the concave edge.

Preferably, the knuckle is made of a metal material. The retaining ring includes: left retaining ring and right retaining ring.

The technical scheme provided by the utility model has the beneficial effects that: the utility model provides a flexible pipe, wherein a cable with cable pipeline detection equipment is arranged in the flexible pipe in a penetrating manner, so that the protection and the guide of the cable are realized; and the adoption of a metal structure ensures high strength and meets various requirements in actual engineering.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below.

In order to achieve the above purpose, referring to fig. 1 to 3, an embodiment of the present invention provides a flexible pipe, which is composed of a plurality of movably connected joints 1, wherein the joints 1 are made of metal materials; each joint 1 comprises: a convex edge 11, a concave edge 12 and a retainer ring 13; the convex edge 11 and the concave edge 12 are formed by machining in a whole machine, the materials of the convex edge 11 and the concave edge 12 can be stainless steel or aluminum alloy, and the outer diameter of the convex edge 11 is preferably smaller than the inner diameter of the concave edge 12 for the convenience of assembly and connection. The retainer ring 13 needs to be partially welded on the concave edge 12 for connection between the adjacent joints 1, and the retainer ring 13 limits the falling off of the adjacent joints 1.

In a specific implementation, a plurality of metal joints 1 are connected to form a flexible pipe, wherein the connection mode between any two metal joints 1 is shown in fig. 2. For convenience of description, two adjacent metal joints 1 are called a first joint 1a and a second joint 1b, when the two metal joints are assembled, the convex edge 11 of the second joint 1b is placed in the concave edge 12 of the first joint 1a, and the retaining ring 13 is welded on the concave edge 12 of the first joint 1a, so that the convex edge 11 of the second joint 1b is limited to be incapable of being pulled out of the concave edge 12 of the first joint 1a, the two metal joints 1 can only rotate and move for a certain angle and distance, and the flexible connection between any two metal joints 1 is realized.

For the convenience of assembly and welding, the retainer ring 13 is divided into a left retainer ring 131 and a right retainer ring 132, and may be designed into a plurality of welding sections.

The effect after the connection of 11 metal joints 2 is shown in fig. 3.

In the embodiment of the present invention, except for the specific description of the model of each device, the model of other devices is not limited, as long as the device can perform the above functions.

Those skilled in the art will appreciate that the drawings are only schematic illustrations of preferred embodiments, and the above-described embodiments of the present invention are merely provided for description and do not represent the merits of the embodiments.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
