Description
Technical field
The present invention relates to the tubing package technique, relate in particular to a kind of tubing connection fittings.
Background technique
In the prior art, the structure that connects tubing through connection fittings has a variety of, and comparatively long what see is after tubing is inserted connection fittings; Tubing is connected fixing with connection fittings through fastening pieces such as screw, rivets; When adopting screw to connect the two, its advantage is to be convenient to dismantle with secondary after connecting be connected, and its defective is that dismounting all need be by instruments such as screw-drivers; Dismounting efficient is lower; And tapped hole is impaired easily in disassembly process, repeatedly possibly cause after the dismounting connecting inefficacy or even can't effectively connecting; When adopting rivet to connect the two, its advantage is that installation efficiency and join strength are higher, and its defective is to be not easy to dismounting; Under the situation of essential dismounting, have to rivet destroyed the rivet that need more renew when installing once more; And, in the process of damage type dismounting, cause tubing impaired easily.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes existing technology, and a kind of simple in structure, easy accessibility, reusable tubing connection fittings are provided.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of tubing connection fittings; Comprise accessory body and bail, said accessory body is provided with and is used for the joint that is connected with said tubing, and said joint is provided with the jack that is used for ccontaining tubing; Said bail is provided with the elastic groove that extends to afterbody from head; The middle part of said bail is provided with radially draw-in groove, and said bail is inserted in the through hole of penetrator and tubing, and said radially draw-in groove is in the edge card tight coupling and the tubing of through hole.
The afterbody of said bail is in being provided with the hand-hole guide portion near an end of draw-in groove radially.
Said radially draw-in groove is provided with the guiding surface that is used to dismantle in the end near the bail head.
The surface of said joint is provided with counterbore along bore periphery, and the head of said bail places said counterbore.
Said counterbore is oval shape, and said bail head is divided into the two ends of the counterbore that is oval shape in the position of elastic groove both sides.
The sectional shape of said elastic groove is V-shaped.
Compared with prior art, the invention has the advantages that:
Tubing connection fittings of the present invention, its simple in structure, easy accessibility directly is inserted in bail in the through hole of penetrator and tubing, makes radially that draw-in groove chucking joint and tubing get final product during assembling; During dismounting; Compress the bottom of elastic groove downwards through the sheet instrument that can insert elastic groove, the head of bail is inwardly shunk automatically, break away from joint and tubing until draw-in groove radially; Last whole bail falls into tubing inside from through hole, accomplishes the constraint of removing butt joint and tubing; Assembling and dissembling process is quick and easy, completion mounting or dismounting operation that can be quick, easy, and the bail of pulling down is also reusable, saves cost.The present invention can also be at the afterbody of bail near an end of draw-in groove radially the hand-hole guide portion being set; The through hole madial wall was along hand-hole guide portion extruding bail when bail was packed through hole into, and bail is from the center pressing of trend elastic groove, and the hand-hole guide portion is fully through the normal position of under the effect of elastic groove, rebounding automatically behind the through hole; Make radially draw-in groove in the edge card tight coupling and the tubing of through hole; The whole erection process is easy and convenient, and bail and through hole all can not receive too much damage, long service life.The present invention can also establish guiding surface in the end near the bail head at draw-in groove radially; In unloading process; When the head of bail inwardly was contracted to guiding surface and contacts with through-hole wall, guiding surface began to play the guiding role, and makes unloading process more smooth and easy, laborsaving; Also played simultaneously the effect of protection bail, it is excessive and damage to avoid bail to receive instrument to compress power.The present invention can also be provided with counterbore in bore periphery, and the head of bail is placed counterbore, thereby guarantees that the accessory surfacing is attractive in appearance, avoids bail to hang hindering other parts or is impacted and impaired by other parts.Counterbore can further be made as oval shape, and the bail head is divided into the two ends of the counterbore that is oval shape in the position of elastic groove both sides, can prevent like this to rotate after bail from packing into, avoids unnecessary wearing and tearing, guarantees join strength.
