Abstract
The utility model discloses a pipe connection device. The pipe connection device comprises two pipes (1), two nuts (2), a hollow connection piece (3), two sets of sealing pieces which sleeve the pipes (1) and two annular limit pieces, wherein four axial limit devices are respectively arranged on the two annular limit pieces and the two pipes (1), one end of each nut (2) is provided with a limit plate (4), two through holes (5) which can sleeve the pipes (1) are formed in the two limit plates (4), the two nuts (2) are respectively connected with two ends of the connection piece (3) in thread mode, and the sealing pieces and the annular limit pieces are sequentially arranged among the nuts (2) and the connection piece (3) in close fit mode. The pipe connection device saves time and labor, can be demounted, and difficultly falls off.
Description
Technical field
The utility model relates to a kind of device that two pipe fittings are linked together, and is specifically a kind of pipe connecting device.
Background technique
Two pipe fittings connect the general mode by welding or snapping and connect.But welding is not only wasted time and energy, and can not dismantle, and uses more inconvenient.Snapping is by utilizing male female two threaded connectors to be connected with two Sealings that are socketed on pipe fitting, during use by two threaded connectors respectively by two Sealing compressive strains close-fitting on pipe fitting.But, due to this be to utilize the structure of close-fitting to reach the object of connection, therefore this fastening structure easily comes off under larger pressure, its functional reliability is poor.
Model utility content
The technical problems to be solved in the utility model is, a kind of pipe connecting device of time saving and energy saving, detachable and difficult drop-off is provided.
The technical solution of the utility model is, a kind of pipe connecting device is provided, and comprises the link of two pipe fittings, two nuts, a hollow, two groups of Sealing and two annular stop parts that are socketed on pipe fitting; Described two annular stop parts and two pipe fittings are respectively equipped with an axially stop block; One end of described two nuts is equipped with a limiting board, and described limiting board is provided with a through hole that can be socketed on pipe fitting; Two described nuts are threaded with the two ends of link respectively; Between described nut and link, close-fitting has Sealing, annular stop part successively.
Described axially stop block comprises two radial projection that are located in annular stop part and is located on pipe fitting for two spacing holes that radial projection is inserted; An annular stop part is comprised of two semi-circular parts; Two described radial projection are located at respectively on two semi-circular parts; Two described radial projection are located at respectively in two spacing holes.
Described Sealing comprises a rubber ring and two plastic hoops; Described rubber ring is located between two plastic hoops.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
The utility model pipe connecting device is connected the object that can reach connection by two nuts with link, then by axially stop block, carries out axial limiting and come off avoiding, and by Sealing, seals.Like this, not only make the utility model pipe connecting device couple together time saving and energy saving, detachable and difficult drop-off.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of pipe connecting device of the utility model, comprises that the link 3, two groups of two pipe fittings 1, two nuts 2, a hollow is socketed in Sealing and two the annular stop parts on pipe fitting 1; Link 3 is provided with an axial passage; Described two annular stop parts and two pipe fittings 1 are respectively equipped with an axially stop block; One end of described two nuts 2 is equipped with a limiting board 4, and limiting board 4 is an integral body with nut 2, and described limiting board 4 is provided with a through hole 5 that can be socketed on pipe fitting 1; Two described nuts 2 are threaded with the two ends of link 3 respectively; Between described nut 2 and link 3, close-fitting has Sealing, annular stop part successively.
Described axially stop block comprises two radial projection 6 that are located in annular stop part and is located on pipe fitting 1 for two spacing holes 7 that radial projection 6 is inserted; An annular stop part is comprised of two semi-circular parts 8; Two described radial projection 6 are located at respectively on two semi-circular parts 8; Two described radial projection 6 are located at respectively in two spacing holes 7.Described Sealing comprises a rubber ring 9 and two plastic hoops 10; Described rubber ring 9 is located between two plastic hoops 10.
During use, first two nuts 2 are penetrated respectively on two pipe fittings 1, then on two pipe fittings 1, penetrate respectively a plastic hoop, then on two pipe fittings 1, penetrate respectively a rubber ring, then on two pipe fittings 1, penetrate respectively a plastic hoop, then by four semi-circular parts 8 respectively to buckling in two pipe fittings 1, then two nuts 2 and link 3 are screwed.
Below only with regard to most preferred embodiment of the present utility model, be described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
