Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides technical solution: the screwed pipe joint convenient for cleaning oil-stain-preventing, including one A casing 1 and two are located at the mounting head 2 at 1 both ends of casing, and mounting head 2 is detachably connected with casing 1, and mounting head 2 is Hollow cylinder, the appearance wall of mounting head 2 offer pin thread 4, and the inner surface wall of mounting head 2 offers the first negative thread 6, casing 1 both ends inner surface wall offers the second negative thread 8, and the inner surface wall of casing 1 is provided with seal pipe 5, and seal pipe 5 and casing 1 are solid Fixed connection, and seal pipe 5 is located at the inside of two mounting heads 2, the inside and outside table wall of casing 1 and mounting head 2 is coated with self-cleaning painting The bed of material 9.

In this practical plan, the both ends of casing 1 are screwed onto using two mounting heads 2, it, can be by turning when being cleared up Dynamic mounting head 2, clears up again after two mounting heads 2 are removed from 1 both ends of casing, reduces the length of screwed pipe joint, be convenient for The inner wall of screwed pipe joint is cleared up, oneself of one layer of oil-stain-preventing is coated by the inside and outside table wall in casing 1 and mounting head 2 Clean dope layer 9, because self-cleaning coating layer 9 has the performance of good oil-stain-preventing, so that greasy dirt is prevented to be infected with screw thread pipe connector, It can be used directly when use, it is more convenient to use without clearing up greasy dirt, pin thread is offered by the appearance wall in mounting head 2 4, the first negative thread 6 is opened up in the inner surface wall of mounting head 2, in connecting screwed tube, can be socketed by pin thread 4, Grafting can be carried out by the first negative thread 6, make screwed pipe joint that there are socket and two kinds of mounting means of grafting, to make screw thread Pipe fitting is more convenient to use, sealing ring 7 is arranged by the both ends inner surface wall in casing 1, because of the bullet with higher of sealing ring 7 When mounting head 2 is transferred to 1 inside of casing, the gap of generation will be engaged by sealing ring 7 for power between pin thread 4 and the second negative thread 8 Sealing, avoid using when fluid engaged between pin thread 4 and the second negative thread 8 generation gap flow out, to improve screw thread The leakproofness of pipe fitting.

Specifically, the both ends inner surface wall of casing 1 is bonded with sealing ring 7, and sealing ring 7 is located at the interior of the second negative thread 8 Side, because of the elastic force with higher of sealing ring 7, when mounting head 2 is transferred to 1 inside of casing, by sealing ring 7 by pin thread 4 and second The gap sealing that generation is engaged between negative thread 8, avoid using when fluid production is engaged between pin thread 4 and the second negative thread 8 Raw gap outflow.

Specifically, mounting head 2 is arranged with gasket 3 close to one end appearance wall of casing 1, mounting head 2 passes through close with casing 1 Packing 3 is tightly connected, and seals mounting head 2 and casing 1 by gasket 3, external dust is avoided to enter mounting head 2 and casing 1 Between gap in, while keeping the leakproofness of screwed pipe joint stronger.

Specifically, the internal diameter and outer diameter of seal pipe 5 are adapted with the internal diameter of mounting head 2 and outer diameter respectively, two mounting heads 2 It is bonded with seal pipe 5, fluid, which flows through screw nipple, will not be such that fluid contacts with casing 1, so as to so that internal surface of sleeve pipe is kept Neatly.

Specifically, pin thread 4 is meshed with the second negative thread 8, mounting head 2 and casing 1 pass through pin thread 4 and the second negative spiral shell Line 8 is detachably connected, and mounting head 2 is cooperatively connected by pin thread 4 and the second negative thread 8, in cleaning, can pass through rotation two Mounting head 2 is disassembled from casing 1, reduces the length of screw nipple, carry out segmentation cleaning, to make by a mounting head 2 The cleaning for obtaining screw nipple is more convenient.

In the present embodiment, gasket 3, seal pipe 5 and sealing ring 7 are all made of rubber material and are made, and have oil resistant, resistance to The performances such as soda acid, resistance to fever and chills, ageing-resistant, it is close to mounting head 2 and casing 1 respectively by gasket 3, seal pipe 5 and sealing ring 7 The gap that generation is engaged between envelope, two mounting head one end to connect and pin thread 4 and the second negative thread 8 is sealed, thus Enhance the leakproofness of screwed pipe joint.

In the present embodiment, self-cleaning coating layer 9 is made of nano material, and nano material has extremely low surface tension, from And there is powerful hydrophobic, oil rub resistance ability, the dirts such as dust greatly reduce with coating surface contact area, to have incomparable Superior automated cleaning characteristic, greasy dirt are tumbled like on lotus leaf in body surface and are left no trace, and can effectively extend guarantor The clean time.

It in connecting screwed tube, in connecting screwed tube, can be socketed by pin thread 4, the first negative spiral shell can also be passed through Line 6 carries out grafting, so that screwed pipe joint is had socket and two kinds of mounting means of grafting, to keep screwed pipe joint use more square Just, at work, because self-cleaning coating layer 9 has the performance of good oil-stain-preventing, it can be mounted directly use, without clearing up oil Dirt, because of the elastic force with higher of sealing ring 7, when mounting head 2 is transferred to 1 inside of casing, by sealing ring 7 by pin thread 4 and second The gap sealing that generation is engaged between negative thread 8, avoid using when fluid production is engaged between pin thread 4 and the second negative thread 8 Raw gap outflow when needing to clean, by rotating two mounting heads 2, mounting head 2 is disassembled from casing 1, reduces spiral shell The length of line connecting tube carries out segmentation cleaning, so that the cleaning of screw nipple is more convenient.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
