Description

  The present invention relates to a sleeve, and more particularly to an easily separable sleeve.

  At present, the interior side of a general working medium separation type air conditioner is connected to an evaporator and a connecting pipe using pipe joints and union nuts. However, a separable joint cannot be used on the indoor side of an air conditioner using a flammable refrigerant. In the conventional design, when the separator is opened, the indoor side is welded directly to the evaporator and the connecting pipe. Adopting quick joints on the outdoor side, such a design can meet standard and safety requirements, but it requires fitting with fittings and union nuts, and the installation process Is complicated, expensive, poorly sealed, and easy to loosen pipe fittings and union nuts, so that the refrigerant may leak and fail to meet assembly standards and safety requirements.

  Currently, some sleeves designed to prevent separation are provided with bumps having force-receiving surfaces and force-release surfaces at the ends of the sleeves.

Referring to FIGS. 1 to 3, the easy-to-install separation preventing sleeve is
A sleeve main body 1 provided with a female screw, and a plurality of bumps 2 distributed along the circumferential direction of the end surface of the sleeve main body 1, wherein the bump 2 has a force release surface and a receiving force that interacts with the mounting jig. A force receiving surface 21 and a force releasing surface 22 include a plurality of bumps 2 positioned on two opposite sides in the circumferential direction of the bumps 2;
A stopper groove 11 is formed in the bump 2, and a stopper member 3 is engaged in the stopper groove 11 so as to prevent the attachment jig from moving in the axial direction of the sleeve body 1.

  Furthermore, the female screw installed in the sleeve body 1 is for facilitating the coupling between the sleeve and other bolts or other members, and the bump 2 has a force receiving surface 21 and a force releasing surface 22. Thus, when the easy-to-attach separation preventing sleeve is attached, the attachment jig and the force receiving surface on the bump 2 act, and the stopper member 3 located in the stopper groove 11 on the bump 2 is connected to the sleeve body. It is possible to prevent movement of the mounting jig from the bump 2 by restricting movement along the axial direction of 1, and mounting is easy.

  Specifically, as shown in FIG. 1, in this embodiment, the force receiving surface 21 on the bump 2 is parallel to the axis of the sleeve body 1, so that the attachment jig and the force receiving surface 21 can be easily combined. This is advantageous for mounting the sleeve. Here, the force release surface 22 is arranged to be inclined with respect to the axis of the sleeve body 1, and when the sleeve is to be separated, the mounting jig is used when the sleeve is mounted. Moves in the opposite direction and slides along the force release surface 22 in which the mounting jig is inclined and cannot be removed.

  Referring to FIG. 1, the stopper groove 11 is positioned on the outermost side of the bump 2 along the radial direction of the sleeve body 1 and the stopper groove 11 extends in the circumferential direction along the sleeve body. A fitting between the stopper member 3 and the stopper groove 11 for limiting the displacement of the tool is prepared.
