Abstract

The utility model discloses an attach fitting, which comprises connecting blocks fixed in two fittings respectively, two connecting blocks protrude a pipe end respectively, which are inserted in the other fittings properly, a corresponding position hole is arranged on two connecting blocks, a through hole is arranged in the corresponding position on a pipe wall, an insert bar is inserted in two connecting blocks through the pipe wall. The corresponding position holes are arranged on two connecting blocks of the attach fitting, connection and removal of two fittings can be realized by inserting in or pulling out the insert bar, and the operation is simple and convenient. At the same time, the fittings joint is fixed with the connecting block, so strength is relatively high. In addition, the joint protruding fittings do not exist at the joint, so integrity of the fittings is not destroyed, and the appearance of the fittings will not be influenced.

Description

A kind of tubing coupling

Technical field

The utility model relates to the jointing of two sections pipe fittings of a kind of connection.

Technical background

Jointing need is used in the connection of two sections pipe fittings, and existing tubing coupling is difficult to guarantee the intensity of joint usually, and the connection of pipe fitting and dismounting trouble comparatively.For fear of above-mentioned defective, folding joint is a kind of good selection.As a kind of jointing of rod member, folding joint can better guarantee the intensity of joint, connects simultaneously and dismantles also comparatively conveniently, and still, its joint protrudes from the joint of pipe fitting, and the associative perception that it has destroyed pipe fitting influences the outward appearance of pipe fitting.

The model utility content

The purpose of this utility model is to provide a kind of connection and dismounting simple, convenient, joint intensity height, and do not influence the tubing coupling of pipe fitting outward appearance.

Tubing coupling described in the utility model, in two pipe fittings, be fixed with contiguous block respectively, two contiguous blocks protrude from pipe end respectively, insert in another pipe fitting with matching, corresponding hole, position is arranged on two contiguous blocks, the tube wall corresponding position a through hole arranged, inserted link is seated in the hole of two contiguous blocks by tube wall.

Corresponding hole, position is arranged on two contiguous blocks of jointing, by inserting or therefrom extracting inserted link, can realize the connection and the dismounting of two pipe fittings in the hole, it is simple, convenient.Simultaneously, the pipe fitting joint be fixed with contiguous block, thereby intensity is higher.In addition, pipe fitting connects by the contiguous block that is fixed in it, and there is not the joint that protrudes from pipe fitting in its joint, thereby does not destroy the associative perception of pipe fitting, can not influence the outward appearance of pipe fitting.

Embodiment

Embodiment 1, as shown in Figure 1, a kind of tubing coupling of the present utility model, in two pipe fittings, be fixed with contiguous block 1,2 respectively, contiguous block 1,2 protrudes from pipe end respectively, inserts in another pipe fitting with matching, and respective threads hole, position 3a is arranged on two contiguous blocks, the tube wall corresponding position a through hole 4 arranged, screw rod 5 is tightened among the tapped hole 3a of two contiguous blocks 1,2 by tube wall.

On jointing two contiguous blocks 1,2 surface of contact respective threads hole, position 3a is arranged, tube wall and tapped hole 3a corresponding position are provided with through hole 4, when pipe fitting connects, use screw rod 5 that two contiguous blocks are screwed and get final product; During dismounting, the screw rod 5 of also only need outwarding winding gets final product; Its connection and convenient disassembly, simple.Simultaneously, the pipe fitting joint be fixed with contiguous block 1,2, thereby joint intensity is higher.In addition, there is not the joint that protrudes from pipe fitting in the pipe fitting joint, thereby does not destroy the associative perception of pipe fitting, can not influence the outward appearance of pipe fitting.

Contiguous block 1,2 in the present embodiment also can be made step-likely, and as Fig. 2, it can further guarantee the intensity of pipe fitting joint, can also prevent that the suffered shearing force of screw rod 5 is excessive simultaneously, guarantees the working life of screw rod 5.

In the present embodiment, on two contiguous blocks tapped hole 3a of relevant position can have two groups or more than, its connection is more firm, and the intensity of joint is also higher, as Fig. 3.

The described contiguous block that is fixed in the pipe fitting can be by being fixed in the

matrix

10,20 on the pipe fitting and forming by the coordinating block 11,21 that screw thread is rotatably connected on the

matrix

10,20, as Fig. 4.

Stable more, firm for pipe fitting is connected, the surface of contact of two contiguous blocks 1,2 can be made the inclined-plane that is an angle with the axis of pipe fitting, as Fig. 5; Or the surface of contact of two contiguous blocks 1,2 made be the male and fomale(M﹠F) that mutually coincide, as Fig. 6.

Embodiment 2, as shown in Figure 7, another kind of tubing coupling of the present utility model, it is fixed with contiguous block 1,2 respectively in two pipe fittings, contiguous block 1,2 protrudes from pipe end respectively, inserts in another pipe fitting with matching, and corresponding hole 3, position is arranged on two contiguous blocks 1,2, the tube wall corresponding position a through hole 4 arranged, pin 5a is seated in the hole 3 of two contiguous blocks 1,2.
