Abstract
The utility model discloses a connecting pipe for the inner unit and the outer unit of an air conditioner, which comprises an intermediate metal pipe. One end or both ends of the intermediate metal pipe are connected with a rubber pipe respectively. The outer end of each rubber pipe is respectively connected with an outer crimping joint. According to the technical scheme of the utility model, the two ends of the connecting pipe are additionally provided with one rubber pipe respectively. In this way, the bending requirement on the connecting pipe during the installation of the air conditioner in the prior art can be completely satisfied. Therefore, by means of the connecting pipe, the air conditioner can be installed at any place conveniently. Meanwhile, the condition that the connecting pipe is out of service due to breakage or other accidents occurred during the transferring process of the air conditioner can be avoided at the same time.
Description
Technical field:
The utility model relates to the connecting tube technical field of inside and outside machine in the refrigeration system, especially relates to the connecting tube of the inside and outside machine of a kind of idle call.
Background technique:
Existing air-conditioning and the used connecting tube of other refrigeration systems are generally processed by copper pipe two ends cover nut and bell mouth expanding, because air-conditioning is in the position at user installation place limitation, cause all connecting tubes all can significantly bend at the place, two ends, connecting tube has plurality of positions to need crooked and bending in installation process, also can some effects to refrigerating capacity, particularly the big pipe connected pipe of cabinet-type air conditioner then also must two ends welded bellows so that install and guarantee refrigeration, cause cost higher.The bellows of Lian Jieing all the bending situation can occur in the process after sale owing to reaching in installation process simultaneously, causes bellows to occur easily splitting and leaks or the explosion phenomenon, therefore is necessary to be improved.
The model utility content:
At the deficiency that prior art exists, the purpose of this utility model provides the connecting tube of the inside and outside machine of a kind of idle call, and it is simple in structure, when having solved present air-conditioning fully and having installed to the bending requirement of connecting tube.
To achieve these goals, the technological scheme that adopts of the utility model is:
The connecting tube of the inside and outside machine of a kind of idle call comprises the intermediate metal pipe, and the one or both ends of intermediate metal pipe are connected with a sebific duct, and the outer end of sebific duct is connected with outer crimping joint respectively.
Further, pressure joint in the middle of the two ends of described intermediate metal pipe are crimped with respectively, the middle pressure joint at intermediate metal pipe two ends is crimped with a sebific duct respectively.
Further, the port of described outer crimping joint is arranged with a nut.
Further, described nut is selected copper nut for use, outer crimping joint behind the suit copper nut outside the outer end of crimping joint be equipped with the horn mouth that matches for the pipeline of inside and outside machine.
Further, described intermediate metal pipe includes but not limited to a kind of in aluminum pipe, copper pipe, steel lining copper line or the copper steel composite pipe.
Further, described intermediate metal pipe is fixed length, and sebific duct is fixed length.
Further, described sebific duct is selected corrosion resistant nylon sebific duct or the sebific duct of anti-the fluorine for use.
Further, the body outer cover of described intermediate metal pipe and/or sebific duct is equipped with thermal insulation pipe.
After adopting said structure, the utility model is compared the advantage that has and is with prior art:
(1), connecting tube of the present utility model is because two ends have increased sebific duct, when having solved present air-conditioning fully and having installed to the bending requirement of connecting tube, can install easily at topographical position arbitrarily, also solve air-conditioning telephone-moving process simultaneously and caused the destroyed or other reasons of connecting tube to cause the out of use situation of connecting tube.
(2), the connecting tube of the present utility model flat phenomenon of pipe of having avoided connecting tube in the bending process, to occur fully, thereby avoided influencing the hidden danger of quality of complete machine
(3), used sebific duct contrast copper corrugated pipe cost reduces about 50% in the connecting tube of the present utility model, simultaneously can promote the application of aluminum pipe in connecting tube energetically, connecting under the situation that adopts aluminum pipe, the processing cost of whole piece connecting tube can be reduced approximately 40%, single connecting tube can realize falling these 50 yuan.
(4), withstand voltage can the reaching more than the 20MPa of sebific duct in the connecting tube of the present utility model, be higher than the 13MPa pressure of copper corrugated pipe far away, can avoid the hidden danger of quality of bellows generation explosion in the present terminal market feedback fully.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, intermediate metal pipe 2, sebific duct 3, outer crimping joint 4, middle pressure joint 5, nut.
Embodiment:
