Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model comprises an inner layer tube 1 and an outer layer tube 2, wherein both ends of the inner layer tube 1 and both ends of the outer layer tube 2 are provided with convex edges, the outer layer tube 2 is slidably sleeved on the inner layer tube 1, the outer wall of the outer layer tube 2 is sleeved with an annular plate 3 sliding along the axis thereof, the annular plate 3 is connected with the convex edge at the left end of the inner layer tube 1 through a plurality of axial rods 4 uniformly distributed on the circumference, and the plurality of axial rods 4 all pass through the convex edge at the left end of the outer layer tube 2; an annular rubber hose 5 is clamped between the annular plate 3 and the convex edge at the left end of the outer layer pipe 2, when the inner layer pipe 1 slides towards the left end relative to the outer layer pipe 2, the inner pipe can pull the annular plate 3 to slide towards the left end through the axial rod 4, and the annular plate 3 extrudes the rubber hose 5 to enable the outer wall of the rubber hose 5 to expand and bulge outwards; a positioning device which can enable the inner layer pipe 1 and the outer layer pipe 2 to slide relatively in a single direction is arranged between the two pipes.

The positioning device comprises a row of axially arranged ratchets 6 arranged on the outer wall of the inner layer pipe 1 and a radial positioning rod 7 arranged at the right end of the outer layer pipe 2, a pressure spring 8 capable of pushing the positioning rod 7 to the axis of the inner layer pipe 1 is arranged at the end part of the positioning rod 7, and the inner end of the positioning rod 7 extends into the ratchets 6 under the action of the pressure spring 8, so that the inner layer pipe 1 can only slide towards the left end relative to the outer layer pipe 2.

The inner layer pipe 1, the outer layer pipe 2, the annular plate 3 and the rubber hose 5 are all cut into two halves along the axis, and the two halves are buckled on the copper pipe to form a complete pipe shape during installation; the buckled structure can realize the installation and the replacement of the device under the condition of not disassembling the copper pipe.

After the air-conditioning copper pipe is installed, an inner layer pipe 1, an outer layer pipe 2, an annular plate 3 and a rubber hose 5 are buckled on the copper pipe from inside to outside in sequence, then the buckled left end of the device is plugged into a wall hole, the right end of the outer layer pipe 2 is enabled to be protruded to be attached to the wall body, then the inner layer pipe 1 is pushed leftwards, the inner layer pipe 1 pulls the annular plate 3 to move leftwards through a plurality of axial rods 4, the annular plate 3 extrudes the rubber hose 5 to enable the outer wall in the rubber hose 5 to expand and protrude outwards, so that the outer wall of the rubber hose 5 is enabled to press the inner wall of the wall hole, the positioning rod 7 is matched with a ratchet 6 to enable the rubber hose 5 not to return, and the device is installed at the end part of the; when needs are dismantled or are changed, outwards pulling locating lever 7, make its inner withdraw from ratchet 6, inlayer pipe 1 can right end return, and rubber hose 5 deformation diminishes to make rubber hose 5 and wall hole loosen, can take off rubber hose 5, annular slab 3, outer pipe 2 and inlayer pipe 1 in proper order.

The utility model discloses can seal the wall hole port of air conditioner copper pipe for a long time and can not drop, only need the lock during installation good back inwards promote inlayer pipe 1 can, the installation is simple and convenient, work efficiency is high, can dismantle and change under the condition of not dismantling the copper pipe moreover, can used repeatedly.
