Abstract

The utility model belongs to the technical field of refrigerators, particularly relates to a movable joint applicable to a refrigerator, and solves the technical problems that a conventional design is unreasonable, the air tightness is poor and the like. The movable joint applicable to the refrigerator comprises a body provided with a medium circulating channel, and is characterized in that the body comprises a main joint body, wherein a first tapered joint is arranged at one end of the main joint body, and a second tapered joint is arranged at the other end of the main joint body; an external taper thread is formed in the first tapered joint; and the taper of the first tapered joint is smaller than that of the second tapered joint. The movable joint applicable to the refrigerator is more reasonable in design and simpler in structure, has low probability of leakage after mounted, good air tightness and strong practicability, and is in accordance with the development tendency of the current social technology.

Description

Be applicable to the union of refrigerator
Technical field
The utility model belongs to the refrigerator technical field, especially relates to a kind of union that is applicable to refrigerator.
Background technique
Pipe joint is the fastening means between pipeline and pipeline, be can dismounting between element and pipeline tie point.Serving as indispensable key player in pipe fitting, it is one of two main composition parts of hydraulic tubing.Pipe joint has various kind, and pipe joint commonly used generally can be divided into two kinds of hard pipe joint and hose couplings.If come minute according to the Placement of pipe joint and pipeline, hard pipe joint has three kinds of flared type, FERRULETYPE and welding types, and hose coupling is mainly the fastening-pressing type rubber hose coupling, and its a kind of instrument that do not need just can be realized the joint of pipeline connection or disconnection.In order to improve the installation efficiency of joint, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of conduit fast connection structure [application number: 200820060571.4], be included in the outer side surface moulding outside thread of a tubular body, one collar inner side surface moulding internal thread, the collar is with the external thread spiro fastening of internal thread and body, while making the relative body rotation of the collar, and the axial displacement that can make to overlap the hoop body, in the time of in water pipe is inserted in body, can be got loose to the location of water pipe by the axial displacement of the collar.In addition, Chinese patent literature also discloses a kind of pipe coupling [application number: 97229150.4], and mainly by forming with externally threaded adapter body, gland nut, stuffing box gland, the adapter body internal surface is conical surface; Gland nut has internal thread; The stuffing box gland outer surface is conical surface, with the inner conical surface of adapter body, matches.
Above-mentioned two schemes has improved the installation efficiency of joint to a certain extent, and still, at least also there is following defect in this two schemes: design unreasonablely, easily reveal after installing, sealing is poor, in addition, is difficult for installing and poor practicability, can't meet usage requirement.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of union that is applicable to refrigerator that rear difficult leakage and good airproof performance are installed is provided.
For achieving the above object, the utility model has adopted following technical proposal: the union that originally is applicable to refrigerator comprises the body with MEDIA FLOW circulation passage, it is characterized in that, described body comprises adapter body, an end in adapter body is provided with the first taper joint, the other end is provided with the second taper joint, in the first taper joint, is provided with outer cone thread, and the tapering of described the first taper joint is less than the tapering of the second taper joint.Obviously, the utility model design is more reasonable, and structure is simpler, after installing, is difficult for revealing and good airproof performance, practical, meets the development trend of current social technology.
In the above-mentioned union that is applicable to refrigerator, the outer surface roughness of described the second taper joint is≤Ra0.8.
In the above-mentioned union that is applicable to refrigerator, described adapter body is hexagon.
In the above-mentioned union that is applicable to refrigerator, described adapter body, the first taper joint and the second taper joint formula that is connected as a single entity.
In the above-mentioned union that is applicable to refrigerator, described the first taper joint is provided with outer chamfering away from an end of adapter body.
In the above-mentioned union that is applicable to refrigerator, described the second taper joint is provided with outer chamfering away from an end of adapter body.
Compared with prior art, this uses novel advantage to be: it is more reasonable to design, and structure is simpler, after installing, is difficult for revealing and good airproof performance, practical, meets the development trend of current social technology.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, body 1, adapter body 11, the first taper joint 12, outer cone thread 12a, the second taper joint 13.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, originally the union that is applicable to refrigerator comprises the body 1 with MEDIA FLOW circulation passage, this body 1 comprises adapter body 11, an end in adapter body 11 is provided with the first taper joint 12, the other end is provided with the second taper joint 13, be provided with outer cone thread 12a in the first taper joint 12, the tapering of described the first taper joint 12 is less than the tapering of the second taper joint 13.Obviously, the present embodiment design is more reasonable, and structure is simpler, after installing, is difficult for revealing and good airproof performance, practical, meets the development trend of current social technology.
Concrete, the outer surface roughness of second taper joint 13 of the present embodiment is≤Ra0.8.Secondly, adapter body 11 is hexagon.
In order to improve structural strength, adapter body 11, the first taper joint 12 and the second taper joint 13 formula that is connected as a single entity.Install for convenient, in the first taper joint 12, away from an end of adapter body 11, be provided with outer chamfering; Be provided with outer chamfering in the second taper joint 13 away from an end of adapter body 11.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used the terms such as body 1, adapter body 11, the first taper joint 12, outer cone thread 12a, the second taper joint 13, do not get rid of the possibility of using other term.Using these terms is only that they are construed to any additional restriction is all contrary with the utility model spirit in order to describe more easily and explain essence of the present utility model.
