Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated.
Embodiment:
To shown in Figure 4, a kind of directly-inserted quick jointed tubular workpieces comprises pipe fitting body 10 like Fig. 1, and the cross section of pipe fitting body 10 is circular, and pipe fitting body 10 is the straight-through type pipe fitting.Two madial wall ends at said pipe fitting body 10 are provided with seal ring 20 and internal tooth packing ring 30 respectively successively along its opening direction, and said internal tooth packing ring 30 has the teeth 30a that tilts to disperse towards said seal ring 20.The madial wall in said pipe fitting body 10 stage casings is provided with annular protrusion 10a, is used for carrying out spacing to the tubing that inserts in the pipe fitting body 10.
In the present embodiment; The madial wall end of said pipe fitting body 10 has the first groove 10b and the second groove 10c that is used to install internal tooth packing ring 30 that is used to install seal ring 20 successively along its opening direction; In the time of can guaranteeing that tubing is in inserting pipe fitting body 10, seal ring 20 can not be shifted with internal tooth packing ring 30.
In the present embodiment, the said first groove 10b is semicircular groove, and the cross section of said seal ring 20 is the circle with the first groove 10b snap fit, can guarantee that seal ring 20 can effectively be fixed in the first groove 10b.
In the present embodiment, the cross section of the said second groove 10c is a font, and the edge of said internal tooth packing ring 30 is connected in the said second groove 10c, can guarantee that internal tooth packing ring 30 can effectively be fixed in the second groove 10c.
In the present embodiment, said internal tooth packing ring 30 is the toroidal of opening.The purpose of an opening of design is that the toroidal that guarantees internal tooth packing ring 30 does not seal, thereby can internal tooth packing ring 30 directly be connected in the second groove 10c through the shape that opening is adjusted internal tooth packing ring 30.If be not designed to the toroidal of opening, just can not internal tooth packing ring 30 be connected in the second groove 10c.
In the present embodiment, said pipe fitting body 10 is the straight-through type pipe fitting, certainly, also can be elbow, threeway or four-way pipe fitting.
In the present embodiment, said internal tooth packing ring 30 is a stainless steel material, can guarantee that internal tooth packing ring 30 has enough toughness, can be rebounded after the bending, and installs also very convenient.
When internal tooth packing ring 30 is installed; Earlier will have intilted internal tooth packing ring 30 with pliers cuts off; Opening has promptly been arranged after cutting off, internal tooth packing ring 30 1 ends of cutting off are put into along the second groove 10c that pipe fitting body 10 presets, the teeth 30a of internal tooth packing ring 30 is to the sealing gasket directional divergence.During use, the tubing of required connection is firmly inserted in the pipe fitting body 10, make tubing pass internal tooth packing ring 30, seal ring 20 successively, arrive annular protrusion 10a, till can't continuing to insert, can accomplish effective connection until tubing.Seal ring 20 is squeezed and can evenly clogs in the space between tubing and the pipe fitting body 10, plays the effect that sealing blocks water.The teeth 30a of internal tooth packing ring 30 can bite the outer wall of tubing under the effect of elastic force and tensile force, tubing is locked.
To insert the problem that the tubing in the said directly-inserted quick jointed tubular workpieces of the foregoing description takes off fast for solving, the present invention also provides a kind of pipe box tube of getting:
As shown in Figure 5, a kind of pipe box tube of getting comprises and pushes the sleeve body 50 that ring plate 40 and an end are connected with the interior ring of pushing ring plate 40.The other end of said sleeve body 50 has the teeth 30a conic-insertion-piece 50a that cooperate, that external diameter progressively reduces with directly-inserted quick jointed tubular workpieces internal tooth packing ring 30, and the external diameter of said sleeve body 50 is less than or equal to the internal diameter of directly-inserted quick jointed tubular workpieces.
In the present embodiment, the hardness of said conic-insertion-piece 50a can guarantee that greater than the hardness of the teeth 30a of directly-inserted quick jointed tubular workpieces internal tooth packing ring 30 conic-insertion-piece 50a can not be out of shape.
In the present embodiment, be provided with a plurality of toughness in the end with conic-insertion-piece 50a of said sleeve body 50 and regulate opening 50b, in the time of can guaranteeing that conic-insertion-piece 50a inserts in the pipe fitting body 10, conic-insertion-piece 50a can guarantee its toughness.
In the present embodiment, the said ring plate 40 of pushing is stainless steel material, copper material or plastics with said sleeve body 50, can guarantee its toughness, and easy to operate when taking out tubing.
When the needs replacement is perhaps taken off tubing; With the said pipe box jacket casing of getting of present embodiment on tubing; The end that is provided with conic-insertion-piece 50a of getting the pipe box tube is pressed into pipe fitting body 10, and conic-insertion-piece 50a withstands the teeth 30a of internal tooth packing ring 30 and it is opened, and this moment, tubing just can take out.
In a further embodiment, like Fig. 6, shown in Figure 7, also can consider the core body 60 of set inside at pipe fitting body 10, core body 60 withstands annular protrusion 10a, and O type circle 80 is set between the inwall of core body 60 and pipe fitting body 10 again.Setting can effectively increase the sealing behind the whole directly-inserted quick jointed tubular workpieces insertion tube material like this.Two ends at pipe fitting body 10 add core body 60, can guide tubing to insert, and play the guiding role; For increasing sealability, dual radial seal is set, core body 60 is provided with two sealed grooves; Put sealing gasket 70 and O type circle 80 respectively; Wherein O type circle 80 is the sealing of first road, and seal ring 20 is formed the second road inner and outer sealing with sealing gasket 70, guarantees that connection pipe fitting the hidden danger of leaking can not occur.
The above embodiment has only expressed embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
