[0024] Embodiment

[0025] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the technical scheme in the embodiment of the application effectively solves the technical problem of aligning the interfaces of the pipelines, and only when the interfaces are aligned can the bolts be inserted and installed, and the pipelines are prevented from being displaced to be accurately installed, and the installation is time-consuming, and the general idea is as follows:

[0026] In view of the problems in the prior art, the utility model provides a kind of air conditioner pipeline connector, including central pipeline 11 and positioning pipe 12, and the side end of central pipeline 11 is fixedly installed with pre-tightening ring 13, and the side end of positioning pipe 12 is fixedly installed with clamping ring 14, by moving central pipeline 11 and positioning pipe 12, central pipeline 11 and positioning pipe 12 are inserted together;

[0027] Positioning assembly, positioning assembly is arranged on the surface of positioning pipe 12, and positioning assembly includes fixed ring 15, two guide plates 16 and converging plate 17, each guide plate 16 and converging plate 17 are in split type structure, and each converging plate 17 slides horizontally at the side end of guide plate 16, in the process of inserting central pipeline 11 and positioning pipe 12, central pipeline 11 drives pre-tightening ring 13 to move, and pre-tightening ring 13 is rubbed with friction block 21, since the end of friction block 21 is inclined plane, pre-tightening ring 13 rubs friction block 21 and generates upward thrust, and friction block 21 slides upward, and reset rod 22 is extruded and shrinks, and pre-tightening ring 13 slides through the end of friction block 21 and is always in butt joint with the side end of clamping ring 14;

[0028] The side end of pre-tightening ring 13 is convex mechanism, the side end of pre-tightening ring 13 is in butt joint with the inside of clamping ring 14, the convex of the side end of pre-tightening ring 13 is inserted into the inside of clamping ring 14, and the butt joint ring of central pipeline 11 and positioning pipe 12 is formed into double seal;

[0029] The bottom end of each folding plate 17 is provided with a friction block 21, and the top end of each friction block 21 is fixedly installed with a reset rod 22. Since the pre-tightening ring 13 frictionally extrudes the friction block 21, the reset rod 22 is compressed in the inside of the folding plate 17. When the pre-tightening ring 13 slides through the end of the friction block 21, the reset rod 22 pushes the friction block 21 to move downward under the reverse force of the reset rod 22, so that the friction block 21 is frictionally connected with the side end of the pre-tightening ring 13. The friction block 21 can be clamped and installed at any position of the pre-tightening ring 13, so that the pre-tightening ring 13 is quickly and fixedly connected.

[0030] The top end of each folding plate 17 is rotatably installed with a pull rod 19, and the pull rod 19 is installed with a deflection buckle 18, so that the deflection buckle 18 swings to one side to generate a pulling force on the pull rod 19. The pull rod 19 is rotatable at the top end of the folding plate 17 to generate a pulling force on the folding plate 17, so that the folding plate 17 drives the friction block 21 to generate an extrusion force on the pre-tightening ring 13, and the central pipeline 11 and the positioning pipe 12 are more closely connected.

[0031] The side end of each guide plate 16 is rotatably installed with a deflection buckle 18 connected with the pull rod 19, and the two side ends of each deflection buckle 18 are provided with bolts. The deflection buckle 18 is connected with the blocking shell 23, and the bolts are rotated to be extruded and fixed with the side end of the blocking shell 23 to increase the stability.

[0032] The top end of each guide plate 16 is fixedly installed with a blocking shell 23, and the side end of each blocking shell 23 is provided with a protective strip 24. The deflection buckle 18 drives the pull rod 19 to move to the side end of the blocking shell 23 by continuously swinging the deflection buckle 18. The top end of the deflection buckle 18 is rotated to first extrude the protective strip 24, so that the protective strip 24 slides into the inside of the blocking shell 23. The deflection buckle 18 is frictionally connected with the side end of the blocking shell 23, and the protective strip 24 is reversely slid. The protective strip 24 is unfolded at the side end of the blocking shell 23 to frictionally position the top end of the deflection buckle 18 to prevent the deflection buckle 18 from being separated.

[0033] Working principle:

[0034] In the first step, the central pipeline 11 and the positioning pipe 12 are in a separated state, the components of the positioning assembly are in a normal position, the reset rod 22 is not extruded, the friction block 21 is in an initial position, the deflection buckle 18 is not connected and fixed with the blocking shell 23, and the pull rod 19 does not generate a large pulling force on the folding plate 17.

[0035] When the central pipe 11 and the positioning pipe 12 are inserted, the central pipe 11 is pushed to be close to the positioning pipe 12. With the movement of the central pipe 11, the side end of the pre-tightening ring 13 also moves, and the pre-tightening ring 13 is in contact with the friction block 21 at the bottom end of the folding plate 17 on the positioning pipe 12. Since the end of the friction block 21 is beveled, the pre-tightening ring 13 generates friction with the bevel of the friction block 21 during the forward movement, thereby generating an upward pushing force, which makes the friction block 21 slide upward and press the reset rod 22, the reset rod 22 is compressed inside the folding plate 17, the pre-tightening ring 13 slides through the end of the friction block 21, and continues to move forward until the side end of the clamping ring 14 is abutted. At this time, the protrusion at the side end of the pre-tightening ring 13 is inserted into the clamping ring 14, cooperates with the abutment ring of the central pipe 11 and the positioning pipe 12, forms a double-sealing structure, and preliminarily realizes the sealing of the pipe connection.

[0036] In the second step, the deflection buckle 18 rotatably installed on the guide plate 16 is manually swung. When the deflection buckle 18 swings to one side, a pulling force is generated on the pull rod 19 connected thereto, the pull rod 19 rotates at the top end of the folding plate 17, simultaneously generates a pulling force on the folding plate 17, makes the folding plate 17 move to the direction of the pre-tightening ring 13, generates a pressing force on the pre-tightening ring 13, further tightens the connection of the central pipe 11 and the positioning pipe 12, makes the abutment more close, abuts the blocking shell 23 fixedly installed at the top end of the guide plate 16, rotates the bolts on both sides of the deflection buckle 18, and after the bolts are rotated, the bolts are pressed and fixed with the side end of the blocking shell 23, increases the stability of the entire positioning assembly, continues to swing the deflection buckle 18, makes the deflection buckle 18 move to the side end of the blocking shell 23, and during the rotation of the top end of the deflection buckle 18, the protective strip 24 at the side end of the blocking shell 23 is first pressed, makes the protective strip 24 slide to the inside of the blocking shell 23. After the deflection buckle 18 rubs into the side end of the blocking shell 23, the protective strip 24 reversely slides and expands at the side end of the blocking shell 23, and the protective strip 24 plays a friction positioning role on the top end of the deflection buckle 18, prevents the deflection buckle 18 from being separated, thereby maintaining the pulling force state of the pull rod 19 and the folding plate 17, and maintaining the close connection of the central pipe 11 and the positioning pipe 12.

[0037] Finally, it should be noted that the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
