Description

Novel protective sleeve

Technical Field

The utility model relates to a refrigeration technology field, concretely relates to connect indoor set of air conditioner and novel protective case of off-premises station.

Background

The air conditioner connecting pipe is used for connecting an indoor unit and an outdoor unit of an air conditioner. In the prior art, the connecting pipe of the air conditioner is generally a protective sleeve of a round straight pipe made of copper material, the air conditioner connecting pipe is sleeved outside the round straight pipe, and the protective sleeve is not durable, is easy to damage, has low safety performance, cannot efficiently prevent water and fire and has short service life; simultaneously, in the installation, can increase the length of air conditioner connecting pipe according to the actual conditions of air conditioner at the on-the-spot installation sometimes, very inconvenient when the intercepting, the installer will be through spouting the sign indicating number on the protective case outside the connecting pipe and confirm length, need take certain time.

Therefore, in order to solve the above problem, the utility model provides a novel protective sleeve, not only durable can not produce because of the installation application of force and warp and make things convenient for the intercepting.

SUMMERY OF THE UTILITY MODEL

The not enough of prior art to the aforesaid, the utility model aims at providing a novel protective case, the utility model provides a connecting pipe insulating tube can realize fire prevention and water resistance and durable, has increased life, the utility model provides a metal collapsible tube makes in the installation, and both ends can effectual resistance external force, avoid warping, influence the use.

The utility model discloses a realize through following technical scheme.

A novel protective sleeve comprises a PE layer, wherein a heat insulation layer, a waterproof layer and a foam layer are sequentially arranged outside the PE layer; the foam layer is equipped with the several annular groove, the thickness of foam layer is 5mm. The utility model discloses mainly used protection air conditioner connecting pipe, concrete mode is as follows:

preferably, the distance between each annular groove is 1 meter, and the depth and the width of each annular groove are both 2mm. Annular groove mainly used note size that sets up, when the workman master when the installation, can pass through the length of whole air conditioner connecting pipe is judged to annular groove's number, and secondly the intercepting is convenient, directly follows recess position intercepting.

Preferably, the PE layer, the heat insulation layer and the waterproof layer and the foam layer are bonded together by epoxy resin glue. The heat-insulating layer and the waterproof layer can effectively block the influence of high temperature and water on the copper pipe in the heat-insulating pipe of the connecting pipe, and indirectly prolong the service life of the whole air-conditioner connecting pipe.

Preferably, the heat insulation layer is made of asbestos, and the waterproof layer is made of waterproof adhesive tapes. Asbestos and waterproof cloth are common materials, and the manufacturing cost cannot be excessively increased.

Preferably, the PE layer is internally provided with copper wires and is embedded in the PE layer in a spiral manner; built-in copper wire has the effect of consolidating protective case the utility model discloses the joining of well steel wire can effectually increase protective case's life under the condition that does not influence the use, and the air conditioner connecting pipe generally can coil and deposit, at the in-process that coils, and the extrusion can be met to the inevitable, adds the steel wire in the protective case after, can reduce the copper pipe because of the damage that the extrusion brought.

The utility model discloses can with the "a protective case production line" looks adaptation of applying simultaneously.

The beneficial effects of the utility model reside in that:

1. the steel wire is arranged in the PE layer and is embedded in the PE layer in a spiral manner, so that the damage is not easy, the service life of the protective sleeve can be effectively prolonged, the copper pipe in the protective sleeve can be effectively protected, and the service life of the copper pipe is prolonged;

2. the utility model discloses the annular groove of well adoption not only can help air conditioner installation staff to see out the length of air conditioner connecting pipe fast and make things convenient for the better intercepting air conditioner connecting pipe of staff for the installation rate.
