(d) It is necessary to use a loose fitting at the joint between the two. 4, as shown in FIG. 5 and FIG. 6, the conventionally used connecting pipe 5〇 usually has a flexible tubular body' and is formed with a plurality of spaced convex portions 51 and recesses 52 on the surface, and each convex portion 51 and concave portion The 52 series are connected to each other. There is a common anti-loose pipe joint on the market, which includes a first joint 6〇, a pressing rubber ring 61, a lock buckle 62 and a second joint 63; the first joint 60 is a hollow block. And having an opening at both ends thereof, wherein an opening is reduced to form an inner diameter smaller than an inner diameter of the block, and an inner wall portion of the first connection 60 is formed with an internal thread portion 6〇1; the pressing rubber ring 61 has a a telescopic elastic annular body having an inner diameter smaller than a maximum outer diameter of the connecting tube 5 ,, the outer diameter of the pressing apron R ί being larger than an inner diameter of the smaller opening of the first joint 60; The anti-loose buckle 62 is a piece, and the sheet body is bent to form a c-shape, and the anti-loose buckle 0 2 w can be pressed on the outer side surface thereof to form an annular sheet body; the second joint 63 is a hollow tube body. The outer wall surface of one end is formed with three external thread portions 631, and the inner and outer thread portions 631 of the diagnostic grasping k are corresponding to the door thread portion 601 of the first joint 60, and the s _ _ 螳 is twisted to form a snail on the outer side wall surface of one end The connecting portion 632 can be connected to a device corresponding to the like. To '. In the actual installation, the official joint of the anti-defense "firstly sighs the first joint 60 ^ ^ on the connecting pipe 50, and secondly, the elastic apron 61 is elastically sleeved on the connecting pipe, and then The anti-loose buckle is disposed at one of the recesses 相邻 adjacent to the chasing rubber ring 61, and is deformed into a ring shape and fixed to the recess 52, and then the end portion of the connection is made. The axial tapping causes the pipe body at the end to be deformed to fix the lock buckle 62 by two: Ρ 51. At this time, the first joint 60 is moved to the mutual engagement with the pressing rubber ring 62. The top end is further coupled with the internal thread portion 6〇 of the first joint 6〇 by the continuation of the second joint 63. The pipe joint is used to position the first joint 60 to the connecting pipe/ 'It will not be loosened on the connecting member 50. However, since the anti-loose buckle is deformed by human tapping to fix the connecting tube 50 and is fixed to the connecting tube 5〇, it is caused by human error every time the installation is performed. There are different degrees. The anti-loose buckle 62 may not be combined with the connecting tube 5, which may be loosened by the deflection of the tube body, or may be excessively knocked. However, the connection pipe 5〇 is broken, causing gas leakage. Therefore, the prior art anti-loose pipe joint has inconvenient installation and may be loosened due to human error or the connection pipe is broken, which needs further improvement. In view of the prior art anti-loose pipe joints, the installation is inconvenient and may cause looseness during the installation process or the risk of cracking of the connecting pipe. The present invention is solved by the following technical means. The present invention is a loose-proof pipe joint. The utility model is disposed at a connecting end of the connecting pipe, wherein the outer side wall surface of the connecting pipe is formed with a plurality of mutually spaced concave concave joints including a first joint, a second joint and two anti-loose pieces; 〃 the first joint The hollow block has an opening at both ends thereof, and the opening I of one end is smaller than the inner diameter of the block, and the inner side wall surface of the first joint is provided with an inner screw and a small opening is sleeved on the connecting tube with a small opening. The first joint is a hollow pipe body, and one end of the outer wall surface is provided with an outer squeezing 4 external thread corresponding to the internal thread of the first joint, and the second joint is externally threaded and the first The internal thread of the head is knotted with each other; the anti-buckle and the sheet are a circular arc-shaped sheet body, and the circular arc-shaped sheet body has a concave shape-side wall surface formed with a plurality of radial directions a protruding tooth corresponding to the concave portion of the connecting pipe; two anti-loose pieces are respectively disposed on two sides of one end of the connecting pipe, and each protruding tooth of the anti-loose piece is respectively located in one of the concave portions of the connecting pipe The two anti-loose pieces are located inside the threaded end of the second joint. The anti-fisting piece has a semi-circular shape, and the two anti-loose pieces are on both sides. The rims are opposite to each other to form a tube body; the splicing slabs are respectively formed on the inner side wall surfaces of the two ends with different inner diameters. The inner diameter of the externally threaded end of the X-joint is larger than the inner diameter of the other end, and the second joint has an outer diameter. The inner diameter of the threaded end corresponds to the outer diameter of the tubular body formed by the two anti-loose sheets. The anti-loose rag gg is better than the S joint, wherein the anti-loose sheet has a circular arc convex portion, and the side wall surface is provided with at least one positioning convex portion in the axial direction; The inner side wall surface of the threaded end is provided with a positioning recess corresponding to the fixed M407323 position of the anti-loose sheet. The anti-loose pipe joint, wherein the two different inner diameters of the inner wall surface of the second joint form an annular class surface, and the class surface 5 has a stop leak %, the anti-loose The sheet abuts against the leak ring at one end and the other end abuts the inner end surface of the smaller open end of the first joint. The anti-loose pipe joint' wherein the inner surface of the second joint and the end portion of the inner wall surface away from the outer thread end further form a ring-shaped abutting slope. The anti-loose pipe joint 'in which the anti-loose sheet protrudes axially from one side edge--the tabs' and the side edges of one of the other anti-loose sheets abut each other. The anti-loose pipe joint, wherein the first: the joint is formed away from the (four) grain end to form a screw portion. The surface of the screw portion has an external thread. According to the above technical means, the two anti-locking pieces are arranged in the pipe joint, and the two anti-bucking pieces can be engaged with each other by the protrusions on the inner side of the piece and the concave parts on the connecting pipe, compared with the prior art. The loose buckle and the setting of the ρ square pine piece are not required to be struck by the thief of the connecting pipe, and the connecting pipe can be prevented from being broken by the tapping. The area of the anti-loose piece contacting the connecting pipe is increased, so that the anti-loose is prevented. The ability is better than the anti-loose buckle for use; the two loose pieces are provided with positioning protrusions on the outer side surface, and the positioning protrusions can be combined with the positioning recesses of the inner wall surface of the first joint to clamp the second joint The contact area between the anti-loose sheet and the connecting tube achieves the advantage that it is not easy to rotate.
