Technical Field

The utility model relates to an agricultural facility and agricultural pipeline technical field, more specifically relates to a pipe fitting connecting device.

Background

With the rapid development of modern agriculture, the national attention on high-standard farmland construction is higher and higher, and water-saving irrigation accessories are also produced. At present, a large number of water-saving irrigation products exist in the market, wherein the connecting fittings of pipelines are important components in the water-saving irrigation products, however, most of related products in the market have some defects, such as: the single accessory has a single function. Taking the common through connection in the market as an example, a single part can only be used for connecting one of the pipelines or the pipe belts, and the two parts cannot be matched with each other.

The function of connecting two sections pipelines of different specifications is generally realized through the connection interval that sets up different diameter specifications to current pipe connection accessory, it can also be equipped with barb structure in order to strengthen frictional force to connect the interval for can fix the pipe fitting of connecting better, avoid droing. However, this design is generally only used to join pipes, and is not able to join two lengths of pipe or to join pipes to one another, and still has certain limitations.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at overcomes the unable tubular product of connecting the different grade type of current connecting piece, the poor defect of suitability, provides a pipe fitting connecting device, can lead to the two kinds of different grade type tubular products of different specification sizes, solve the poor problem of current connecting piece suitability. The utility model discloses can arrange connecting tube or pipe strap in a flexible way, and the component is few, low in production cost, has stronger practicality.

In order to solve the technical problem, the utility model discloses a technical scheme is:

the utility model provides a pipe fitting connecting device, including the through joint, the through joint both ends all are equipped with the connecting portion of two section at least different diameters, the outer wall of connecting portion is equipped with the barb structure, the through joint outer wall is equipped with the apron of cramping it, the apron inner wall be equipped with the groove structure that barb structure combines closely.

The utility model discloses a theory of operation does: and connecting one section of the two sections of pipelines or pipe belts to be connected with a connecting part at one end of the straight-through joint, connecting the other section of the pipelines or pipe belts to be connected with a connecting part at the other end of the straight-through joint, wherein the selected positions of the connecting parts with different diameters depend on the inner diameters of the pipelines or pipe belts to be connected. When connecting tube, the barb structure that connecting portion outer wall was equipped with can form the interference with the pipeline and be connected, makes the pipeline be difficult for droing. When the pipe belt is connected, a cover plate with a hooping effect is required to be installed on the outer side of the pipe belt, and the groove structure arranged on the inner wall of the cover plate can be matched with the barb structure to tightly fix the connected pipe belt. The cover plate can be detached separately, so that when the pipe band and the pipe need to be connected, the cover plate can be installed at one end of the pipe band, and the cover plate does not need to be installed at one end of the pipe, so that the assembly in the pipe band-pipe connection process is completed.

Furthermore, the straight joint comprises a first straight joint and a second straight joint detachably connected with the first straight joint, a first assembling portion is arranged at one large-diameter end of the first straight joint, and a second assembling portion matched with the first assembling portion is arranged at one large-diameter end of the second straight joint. The straight-through joint is of a detachable structure and can be detached into two sections of conical straight-through parts, namely the first straight-through part and the second straight-through part. The first straight-through and the second straight-through are respectively provided with connecting parts with different diameters for matching pipelines or pipe belts with different diameters. The first straight through and the second straight through are respectively provided with a first assembling part and a second assembling part at one large-diameter end of the first straight through and the second straight through, and are connected through the first assembling part and the second assembling part. Can dismantle the design makes the utility model discloses when needing to interconnect between multistage pipeline or pipe strap, needn't follow pipeline or pipe strap lift off on the connecting portion, another pipeline or pipe strap are gone up to the repacking, only need be connected first direct-through and input pipeline or pipe strap, directly lead to a plurality of second and be connected with a plurality of output pipeline or pipe strap, when different output pipeline or pipe strap are connected to needs, dismantle, assemble simply the utility model discloses can accomplish the change of connection object.
