Abstract
Provided is a metal cutting ferrule which is used for stoutly connecting a metal pipe and a metal pipe connector. The metal cutting ferrule is more convenient to install and disassemble. The metal cutting ferrule can not be damaged even being frequently disassembled. The metal cutting ferrule comprises a clamping base, a clamping ring and at least three clamping claws. The clamping claws are arranged along the circumference of the clamping ring. Each clamping claw comprises a first slope plate which expands outward. One end of each first slope plate is provided with a first bending face formed by bending the end inward, and the end is far away from the clamping ring. Each first bending face is connected with a second slope plate. One end of the second slope plate is provided with a second bending face formed by bending the end inward, and the end is far away from the first bending face.
Description
Technical field
The utility model belongs to the cutting ferrule technical field, specifically relates to a kind of metal ferrule for connection metal pipe and metallic pipe coupling.
Background technique
Traditional metal tube is connected with metallic pipe coupling generally to be and is threaded or welds, and is threaded or welds all to exist installation efficiency low and the problem of poor sealing occurs easily.The metallic pipe coupling that a kind of quick envelope is pressed appears in prior art, described metallic pipe coupling comprises interior shoulder hole, bulge loop groove and ring-type card pressure mouth, but have simultaneously following problem: metal tube when mounted, just can be connected to ring-type card pressure mouthful place after metal tube end need to being squeezed out bulge loop, and being squeezed out the bulge loop of pressing mouth to cooperate with the ring-type card, metal tube end increased difficulty of processing, also not too convenient during installation and removal, when often dismantling, cause easily the damage of joint.
The model utility content
Technical problem to be solved in the utility model is, even if a kind of metal ferrule that also is difficult for causing damage for firmly connection metal pipe and metallic pipe coupling, the more convenient often dismounting of installation and removal is provided.
Technical solution of the present utility model is, a kind of metal ferrule with following structure is provided, it comprises deck, snap ring and at least three claws that are fixedly connected sequentially, described claw circumferentially arranges along snap ring, each claw comprises one to the first swash plate that extends out, the first swash plate is provided with to bend inwards away from snap ring one end and forms the first fold bent face, and the first fold bent face is connected with the second swash plate, and described the second swash plate is provided with the second folding surface that bends inwards away from the end of first fold bent face.
After adopting above structure, the utility model metal ferrule compared with prior art has the following advantages:
Because the utility model metal ferrule comprises at least three claws, press mouth to compress into from the ring-type card of metallic pipe coupling at the deck end of metallic pipe coupling in use, deck inserts metal tube after being against metallic pipe coupling, the deck end of metal tube toward metallic pipe coupling advanced, stop when motionless until push away, metal tube is installed into metallic pipe coupling, and the second folding surface of claw is pushed against the metal tube outer circumferential face.When pulling outward pipe, first fold bent face in the claw stretches outward, the inclined-plane is propped up by the metallic pipe coupling of outside, angle between first fold bent face and the inclined-plane increases, the second folding surface tightly is against the metal tube outer circumferential face, so that claw and metal tube between frictional force increase, metal tube is not easy to be drawn out and, and metal tube firmly is connected with metallic pipe coupling; During dismounting the first fold bent face of claw curved inwardly and tighten up, active force between the second folding surface and the metal tube reduces even removes fully, can smoothly metal tube be pulled down, namely mount and dismount more convenient, even if also not fragile metal tube, metallic pipe coupling and metal ferrule of installation and removal repeatedly.
As preferably, described the second swash plate middle part is provided with projection, when needing the dismounting metal tube, claw inwardly tightened up a little claw to be tightened up toward in when projection contacts with the metal tube outer circumferential face again can extract smoothly metal tube out, be unlikely to because judging that to cause the bending angle of claw excessive, repeatedly the excessive claw that causes easily of bending angle shortens working life.
As preferably, described snap ring, claw and deck are an integral body, and overall structure is more firm, and is easy to use.
As preferably, described claw has four, circumferentially evenly arranges along snap ring, and four claws can be from four aspects chucking metal tubes, tightens more firm and metal tube is stressed more even.
Description of drawings
Figure 1 shows that the structural representation of the utility model metal ferrule.
Figure 2 shows that Fig. 1 plan structure schematic representation.
Figure 3 shows that the structural representation when the utility model metal ferrule is installed.
Shown in the figure: 1, snap ring, 2, claw, the 2.1, first inclined-plane, 2.2, the first fold bent face, the 2.3, second folding surface, 2.4, projection, the 2.5, second inclined-plane, 3, deck, 4, metal tube, 5, metallic pipe coupling, 5.1, interior shoulder hole, 5.2, the bulge loop groove, 5.3, the ring-type card presses mouthful.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, Fig. 2 and shown in Figure 3, it comprises deck 3, snap ring 1 and at least three claws 2 that are fixedly connected sequentially the utility model metal ferrule, described claw 2 circumferentially arranges along snap ring 1, each claw 2 comprises one to the first swash plate 2.1 that extends out, the first swash plate 2.1 is provided with to bend inwards away from snap ring 1 one ends and forms first fold bent face 2.2, first fold bent face 2.2 is connected with the second swash plate 2.5, and described the second swash plate 2.5 is provided with the second folding surface 2.3 that bends inwards away from the end of first fold bent face 2.2.
Described the second swash plate 2.5 middle parts are provided with projection 2.4.In the present embodiment, described protruding 2.4 is salient point.
Described snap ring 1, claw 2 and deck 3 are an integral body.
Described claw 2 has four, circumferentially evenly arranges along snap ring 1.
The utility model metal ferrule adopts 304L stainless steel material processing and fabricating to form, and elasticity is better and high temperature resistant.
Described metallic pipe coupling 5 comprises interior shoulder hole 5.1, bulge loop groove 5.2 and ring-type card pressure mouth 5.3, during installation, press mouth 5.3 to compress into from the ring-type card of metallic pipe coupling 5 at deck 3 ends of the utility model metal ferrule first, deck 3 pushes against metallic pipe coupling 5 rear insertion metal tubes 4, deck 3 ends of metal tube 4 toward metallic pipe coupling are advanced, stop when motionless until push away, metal tube 4 is installed into metallic pipe coupling 5; During dismounting, because claw 2 elasticity are better, claw 2 curved inwardly tighten up, namely claw 2 no longer is against metal tube 4 outer circumferential faces, and the frictional force between claw 2 and the metal tube 4 disappears, and metal tube 4 is pulled down.
