Abstract

The utility model relates to a pipe joint which is formed by combining a joint, a rotary head, two leakage-proof gaskets, a supporting head, a nut, etc. The pipe joint can be bent at any angle by making use of the design of the rotary head, and a jointing pole of the joint is sheathed in a through hole of the rotary head to be riveted; thus, the combination can become firmer. The utility model has the advantages that the pipe joint can be bent arbitrarily and freely, the pipe joint rotates in a flexible mode and is operated conveniently, etc.

Description

A kind of pipe joint

The utility model relates to a kind of pipe joint.

At present, general pipe joint A forms (as shown in Figure 1 and Figure 2) by metal tube processing car system, this structure is divided into setting firmly holds A1 and sleeve end A2, in the center is the perforation A3 that runs through, and sleeve end A2 is the design of multistage circular layer, and making this set firmly end A1 can join with other things, sleeve end A2 then can join with flexible pipe, and the use shortcoming of this structure promptly is to do other angle turnover skew use, then often is subjected to landform, atural object restriction in the use, and more inflexible shortcoming in the use is arranged.

The purpose of this utility model provide a kind of have reach degrees of freedom and bend, rotate pipe joint flexible, easy to operate practicality arbitrarily.

For achieving the above object, the utility model is taked following design proposal:

A kind of pipe joint, it has sleeve end, bores a hole, sets firmly end, it is characterized in that:

Be provided with a joint, the center is hollow and connects shape, and is extended with a linking roofbolt;

Be provided with a rotary head, for spherical shape and be the hollow through hole, through hole joining rod styletable face is a side grain, makes its cover be placed on the linking roofbolt of joint and is followed fixing with viscose glue;

Be provided with two leakage washers, it is forward and backward to be located at rotary head, and the external leakage effect of obstruct liquid (oxygen) is arranged;

Be provided with one and accept head, be positioned at the leakage washer outside, front end is shaped on screw thread for holding the circular arc spherical surface of rotary head contact activity in outer surface;

Be provided with a nut, be connected between roofbolt and the rotary head at joint tail end, its internal thread thinks and is screwed together in the screw thread of accepting head surface, and becomes retaining edge than the roundlet footpath in front end hollow face, and this retaining edge circle footpath is circular-arc.

After making up mutually by above-mentioned each element, can make rotary head in winding more firmly outside, also can reach any bending of degrees of freedom, the practical effect of rotation flexible operating benefit.

For the compound mode that makes this rotary head and joint more firm, the aperture and the rotary head of the linking roofbolt of joint can be riveted, its riveted joint can be done to be a plurality of riveting points mode with the aperture of full side face riveted joint or linking roofbolt, rotary head is fixed in the aperture that is connected roofbolt is a plurality of riveting points mode, rotary head is fixed on the linking roofbolt; All can be with can be more firm in the linking roofbolt of this pipe joint and the rotary head winding.

The side grain place of rotary head changes being set as hole, recessed rank, aperture place's reaming of the linking roofbolt of joint and be limited on the hole end surface of recessed rank and become concealed riveted fixing.Also can reach firm riveted joint effect.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 9 is the third textural association sectional view of the present utility model

Figure 10 is the 4th a kind of structural upright exploded view of the present utility model

See also Fig. 3, Fig. 4, shown in Figure 5, the utility model includes:

Be provided with a joint 10, the center is hollow and connects shape 11, and is extended with a linking roofbolt 20, and aperture 30 ora terminalis are to be made into thin shape;

Be provided with a rotary head 2, for spherical shape and be hollow through hole 21, it is a side grain 23 that through hole 21 is connected welding column 20 end faces, its cover is placed on the linking roofbolt 20 of joint 10, and force the outside reaming of aperture 30 place's ora terminalis of the linking roofbolt 20 of joint 10 with external force by aperture 30 ora terminalis that are connected roofbolt 20 with instrument, facility (as drift or riveting machine), and be limited on the side grain 23 of rotary head 2 and riveted fixing;

Two leakage washers 3, it is forward and backward to be located at rotary head 2, and the external leakage effect of obstruct liquid (oxygen) is arranged;

Be provided with one and accept 4, be positioned at leakage washer 3 outsides, front end is shaped on screw thread 42 for holding the circular arc spherical surface of rotary head 2 contact activities in outer surface;

Be provided with a nut 5, between joint 10 tails ends was connected roofbolt 20 and rotary head 2, its internal thread 51 thought to be screwed together in and accepts a screw thread on 4 surfaces 42, and became retaining edge 52 than the roundlet footpath in front end hollow face, and these retaining edge 52 circles are circular-arc directly;

After making up mutually by above-mentioned each element, can make rotary head in winding more firmly outside, also can reach any bending, flexible, the easy to operate practical effect of rotation of degrees of freedom.

Moreover, the utility model in the compound mode of these rotary head 2 joints 10 also can be divided into following several;

Please cooperate Fig. 6, Fig. 7 again, the combination of rotary head 2 joints 10 of the present utility model is implemented structure for second kind and also side grain 23 places with rotary head 2 can be changed to be set as hole, recessed rank 24, make the aperture 30 places reaming of the linking roofbolt 20 of joint 10, and be limited on 24 end faces of hole, recessed rank and become concealed riveted fixing, also can reach and aforementioned exposed riveted joint mode same effect.

The third can implement structure for the utility model for Fig. 8, Fig. 9, promptly is the linking roofbolt 20 of joint 10 to be established in thread 14 mutual screw lock modes with rotary head 2 endoporus reach combination.

In addition, as Figure 10, shown in Figure 11, linking roofbolt 20 ends of this joint 10 are provided with caulking groove 15, protrude a bit of embedding lip 22 in rotary head 2 endoporus ora terminalis, and utilize the embedding lip 22 of rotary head 2 to carry out the embedding folder with the caulking groove 15 that is connected roofbolt 20, and joint 10 can firmly be joined with rotary head 2.

More than the compound mode of these rotary head 2 joints 10 all can reach firm winding effect.

In sum, the utlity model has and reach the free degree and bend arbitrarily, rotate flexible, easy to operate reality With etc. advantage.
