Preferably, at least three ball grooves are arranged on the extrusion block at equal intervals.

Preferably, a metal strip is arranged on the lining pipe, the metal strip is tightly attached to the lining pipe, the metal strip is fixed to the lining pipe in an adhesive mode, and the sliding block is fixed to the surface of the metal strip in a welding mode.

Compared with the prior art, the utility model discloses carry out the joint through swing joint device between interior bushing pipe and the outer tube, this kind of connected mode is easily taken of interior bushing pipe, conveniently dismantles the change.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the connection of the slider to the liner tube.

In the figure: 1. an outer tube; 11. a limiting hole; 12. a chute; 2. a liner tube; 21. a slider; 22. a metal strip; 23. extruding the block; 24. a limiting plate; 25. a tension spring; 26. a ball groove; 27. and a ball.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

The assembly of the inner liner tube 2 as shown in fig. 1-2 comprises an outer tube 1 and an inner liner tube 2, wherein a sliding groove 12 and a limiting hole 11 are formed in the wall of the outer tube, the limiting hole 11 is a cylindrical hole, the limiting hole 11 penetrates through the wall of the outer tube and is symmetrically arranged at two ends of the outer tube 1, the inner liner tube 2 is arranged in the outer tube 1 in a penetrating manner, a sliding block 21 is arranged on the inner liner tube 2, the sliding block 21 is arranged in the sliding groove 12, an extrusion block 23 is arranged on the sliding block 21, the extrusion block 23 is a cylindrical block, the diameter of the extrusion block 23 is the same as that of the cylindrical hole, the extrusion block 23 is arranged in a containing groove on the sliding block 21, a limiting plate 24 is arranged at the tail of the extrusion block 23, the limiting plate 24 is welded and fixed at the tail of the extrusion block, a telescopic spring 25 is further arranged in the containing groove, the, the ball groove 26 is clamped with a ball 27.

The utility model provides a quick dismantlement principle of bushing pipe 2 and outer tube 1 is realized in this application, the slider 21 that sets up on bushing pipe 2 is provided with extrusion piece 23, through the extrusion of the expanding spring 25 that sets up in extrusion piece 23 below, can realize extrusion piece 23 extrusion activity about the storage tank in slider 21, the ball 27 that sets up on extrusion piece 23 makes things convenient for slider 21 card to slide when going into in spout 12, be provided with spacing hole 11 on outer tube 1, spacing hole 11's aperture is the same with extrusion piece 23, so slider 21 can not get into spacing hole 11, slider 21 only can slide in spout 12, when extrusion piece 23 card goes into spacing hole 11, the card of bushing pipe 2 has been accomplished establishes fixedly, and simultaneously, when bushing pipe 2 in needs take out, only need extrude extrusion piece 23 on the slider 21 downwards, alright realize taking of bushing pipe 2.

Furthermore, in order to meet the sealing requirement of the outer tube 1, a sealing ring can be arranged on the inner wall of the limiting hole 11, and when the extrusion block 23 is clamped into the limiting hole 11, the sealing ring can play a role in sealing.

Furthermore, at least three ball grooves 26 are equidistantly arranged on the extrusion block 23, so that the friction of the extrusion block 23 sliding in the sliding groove 12 can be reduced, and the lining pipe 2 can be conveniently put in and taken out.

Further, a metal strip 22 is arranged on the lining pipe 2, the metal strip 22 is tightly attached to the lining pipe 2, the metal strip 22 is fixed to the lining pipe 2 in an adhesive mode, and the sliding block 21 is fixed to the surface of the metal strip 22 in a welding mode. On the one hand metal strip 22 adhesive fixation on interior bushing pipe 2, under the external heating condition, because most bonding glue is heated can be inefficacy, the dismantlement of the metal strip 22 of being convenient for, the change of taking of the slider 21 of also being convenient for, simultaneously, slider 21 and metal strip 22 welding are fixed, and joint strength is high.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
