Abstract

The utility model discloses a fast connector for split type air-conditioners, comprising a female joint and a male joint. A valve component is respectively arranged in the female joint and the male joint. The female joint and the male joint are connected by a connecting gear. The female joint is a copper pipe A connected with the air conditioner. The copper pipe An is connected with a pipe joint A. A movable sleeve and a spring are arranged in the pipe joint A. A central shaft is arranged in the movable sleeve. The central shaft is connected with a valve core. The male joint is a copper pipe B connected with the air conditioner. The copper pipe B is connected with a pipe joint B. The male joint is provided with steps. A clog and a spring are arranged in the pipe joint B. The clog of the male joint is contacted with the valve core of the female joint. When the indoor unit and the outdoor unit of the air conditioner are not arranged and used, the valves of the female joint and the male joint are respectively closed. When the female joint and the male joint connecting, the steps in the male joint push the movable sleeve of the female joint. The central shaft and the valve core of the female joint push the clog of the male joint. Therefore, two valves are open, and refrigerant agent flowing pipelines ofthe indoor unit and the outdoor unit are fast connected.

Description

Split-type air conditioner snap joint

Technical field

The utility model relates to split-type air conditioner and mobile air conditioner accessory, mainly relates to the jointing of cold-producing medium pipe between the indoor set of split-type air conditioner and mobile air conditioner and the off-premises station.

Background technology

Split-type air conditioner is made up of indoor set and off-premises station, between two machines, connect the refrigerant system joint, prior art uses stop valve as joint, the shortcoming of its existence has: the one, connect trouble when installing an air-conditioner, it is very big to take a lot of work, countries such as Europe often installation fee be higher than this machine of air-conditioner expense; The 2nd, in the attended operation process, can cause lower amount of refrigerant to leak; The 3rd, have air when installing and enter in the system.

Summary of the invention

The purpose of this utility model provides and a kind ofly apace two flow of refrigerant circuits that are under the pressured state is coupled together, and can prevent from the attended operation process, to cause lower amount of refrigerant to leak, and prevent that air from entering the split-type air conditioner snap joint in the system.

The technical scheme of the utility model split-type air conditioner snap joint is: a female joint and a male joint are arranged, in mother, male joint, valve module is installed separately, female, male joint is linked to each other by bindiny mechanism, it is characterized in that described female joint is the copper pipe first that connects with air-conditioning, the copper pipe first links to each other with the pipe joint first, movable sleeve and spring are installed in the pipe joint first, central shaft is arranged in the movable sleeve, central shaft is connected with spool; Described male joint is the copper pipe second that connects with air-conditioning, and copper pipe second links to each other with pipe joint second, and male joint is shaped on step, installs in the pipe joint second and stops up and spring, and the obstruction of male joint contacts with the spool of female joint.

The utility model is not when indoor apparatus of air conditioner and off-premises station are are installed and used, and female joint and male joint be valve-off separately, is in sealing state, do not have and open.When female joint is connected with male joint, be subjected to external force (bindiny mechanism) effect, step in the male joint promotes the female joint movable sleeve, and the central shaft of female joint and spool are pushing away male joint and stopping up, and the valve module in mother, the male joint is opened simultaneously, just the indoor set of split-type air conditioner is connected with the flow of refrigerant circuit of off-premises station, operation is very convenient, and connection speed is very fast, is easy to, and do not have cold-producing medium in the connection procedure and leak, air is entered in the refrigeration system.And as long as with the pipe joint alteration of form of male and female joint, can change into easily and being threaded, promptly can be used as an independently snap joint, be applicable to mobile air conditioner.

The specific embodiment

The utility model discloses a kind of common split-type air conditioner that is applicable to, particularly be applicable to mobile air conditioner, but also can be used for the snap joint in the base, a female joint and a male joint are arranged, valve module is installed in female joint and male joint separately, and when the indoor set of air-conditioning and off-premises station were not were not installed and used, valve module separately was in sealing state, female, male joint is linked to each other by bindiny mechanism, relies on the connection of bindiny mechanism that two valve modules are opened.The structure of its female joint such as Fig. 1, Fig. 2 and shown in Figure 4 are the copper pipe first 1 that connects with air-conditioning, and copper pipe first 1 is connected with pipe joint first 3, movable sleeve 4 is installed in the pipe joint first 3, and movable sleeve 4 cooperates with spring 2, and external seal O shape circle 7 is arranged, central shaft 5 is arranged in the movable sleeve 4, and the central shaft head is connected with spool; Its structure of described male joint is as Fig. 1, Fig. 3, shown in Figure 5, be the copper pipe second 13 that connects with air-conditioning, copper pipe second 13 links to each other with pipe joint second 8, outside seal may 12 is arranged, and male joint is shaped on step 82, and obstruction 9 and spring 10 are installed in the pipe joint second 8, the obstruction 9 of male joint contacts with the spool of female joint, after both conflict effects, valve open, as shown in Figure 1.The spool of its female joint is the sealing ring 6 that connects central shaft 5, and as Fig. 2, shown in Figure 4, sealing ring 6 is fixed by securing member 61, is shaped on sealing inclined-plane 41 at the oral area of movable sleeve 4, and sealing inclined-plane 41 is sealed and matched mutually with the place, right angle of sealing ring 6.Described when opening valve, be that movable sleeve 4 contracts toward in, movable sleeve inclined-plane and sealing ring 6 right angles are disengaged.Sealing ring 6 can be to adopt polytetrafluoroethylmaterial material made.As Fig. 3 and shown in Figure 5, stop up 9 head in male joint plastic sealing ring 91 is installed, be shaped on sealing inclined-plane 81, sealing inclined-plane 81 and sealed to each other cooperation of plastic sealing ring 91 right angles at the oral area of pipe joint second 8.Its described plastic sealing ring 91 is that polytetrafluoroethylmaterial material is made, and plastic sealing ring 91 is fixed by copper nut 92.So open valve is to stop up 9 inwardly to contract, and spring 10 makes the sealing inclined-plane 81 of pipe joint second 8 disengage with plastic sealing ring 91 right angles by compression.The bindiny mechanism of its mother, male joint is a lot, for example can be that trip gear connects or is threaded, and trip gear is that mother, male joint are pulled to together; Be threaded as Fig. 4, shown in Figure 5, be applicable to mobile air conditioner, after separately blind nut 14,15 is taken down, with pipe joint second 8 ' spinning in pipe joint first 3 ' in get final product.The technical program can adopt single-row structure, as shown in Figure 1, also can adopt double column structure.
