Abstract

The utility model provides a connecting sleeve for a multipurpose refrigerating pipe, belonging to the technical field of pipeline connection and solving the problem that connecting sleeves of the prior art have single using functions. The connecting sleeve comprises a connecting sleeve body, wherein the external surface of the connecting sleeve body is shaped like a regular hexagon; an internal thread is arranged in the connecting sleeve body; a cylindrical boss is also arranged on one side of the connecting sleeve body and is provided with an external thread; first grooves are also formed in the external walls of the boss and are formed between the external thread of the boss and the connecting sleeve body; second grooves are also formed in the internal walls, close to the boss, of the connecting sleeve body. The connecting sleeve can serve as a nut and a filter besides a connecting pipeline, thus achieving the multipurpose effect.

Description

A kind of multipurpose refrigerator pipes connecting sleeve
Technical field
The utility model belongs to the pipeline connection technology field, relates to a kind of connecting sleeve, especially relates to a kind of refrigerator pipes connecting sleeve.
Background technique
A kind of transition piece that public connector is connected with female connector of connecting sleeve, existing connecting sleeve function is simple, can only be for connecting, and do not possess other purposes.
Chinese patent literature discloses a kind of connecting sleeve [application number: 201220402942.9], this connecting sleeve is hollow barrel-type, one end is provided with a circle boss along its inner chamber peripheral wall bottom, this boss has two symmetrical axial bayonet sockets along its circumferencial direction, thereby described boss forms and the snap ring matched with public connector, the other end of described connecting sleeve is provided with two symmetrical projections along its inner chamber peripheral wall bottom, and this projection forms and wants with the order connector stuck point coordinated.This patent has advantages of stable connection, firm.
But the function of the connector of such scheme is still more single, be only used for connecting public, order connector, and can not be as other purposes.
The model utility content
The purpose of this utility model is for the problems referred to above, and a kind of multipurpose refrigerator pipes connecting sleeve is provided, and the connecting sleeve that has solved prior art is used the problem of function singleness.
For achieving the above object, the utility model has adopted following technical proposal: a kind of multipurpose refrigerator pipes connecting sleeve, comprise the connecting sleeve body, the outer surface of described connecting sleeve body is regular hexagon, the connecting sleeve body is provided with internal thread, a side at the connecting sleeve body also is provided with a columniform boss, described boss is provided with outside thread, also be provided with the first groove on the outer wall of boss, described the first groove, between the outside thread and connecting sleeve body of boss, also is provided with the second groove on the inwall of the connecting sleeve body near boss.
At above-mentioned a kind of multipurpose refrigerator pipes connecting sleeve, described connecting sleeve body is identical with the internal diameter of boss.
A kind of multipurpose refrigerator pipes connecting sleeve above-mentioned also is provided with a filter member in the second groove.
At above-mentioned a kind of multipurpose refrigerator pipes connecting sleeve, described filter member comprises the filter screen that the He Yu outer ring, outer ring made from elastic material is fixedly connected with.
At above-mentioned a kind of multipurpose refrigerator pipes connecting sleeve, described filter screen is that stainless steel material is made, and aperture is the 20-100 order.
At above-mentioned a kind of multipurpose refrigerator pipes connecting sleeve, described outer ring and the second groove are interference fit.
Compared with prior art, the utility model has the advantage of:
1, boss of the present utility model is identical with the internal diameter of connecting sleeve body, and the connecting sleeve body is provided with internal thread, thereby connecting sleeve can be used as nut.
2, boss is provided with groove, can in groove, place seal ring, thereby increases the sealing effect of connecting sleeve.
3, be provided with filter member in the connecting sleeve body, connecting sleeve can be used as filter.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides;
Fig. 2 is the structural representation after the utility model is placed filter screen;
The left view that Fig. 3 is Fig. 1;
The structural representation that Fig. 4 is filter screen.
In figure, connecting sleeve body 1, boss 2, the first groove 3, the second groove 4, filter member 5, outer ring 51, filter screen 52.
Embodiment
As Figure 1-4, a kind of multipurpose refrigerator pipes connecting sleeve, comprise connecting sleeve body 1, the outer surface of described connecting sleeve body 1 is regular hexagon, connecting sleeve body 1 is provided with internal thread, it is characterized in that, a side at connecting sleeve body 1 also is provided with a columniform boss 2, described boss 2 is provided with outside thread, also be provided with the first groove 3 on the outer wall of boss 2, described the first groove 3 is between the outside thread and connecting sleeve body 1 of boss 2, seal ring is embedded in the first groove 3, can play the seal action between boss 2 and connection pipe fitting, also be provided with the second groove 4 on the inwall of the connecting sleeve body 1 near boss 2.
Described connecting sleeve body 1 is identical with the internal diameter of boss 2, and this design can be used connecting sleeve body 1 as nut, and when bolt and connecting sleeve body 1 are spirally connected, the redundance of bolt can pass from boss 2.
Also be provided with a filter member 5 in the second groove 4, described filter member 5 comprises the filter screen 52 that the 51He Yu outer ring, outer ring 51 made from elastic material is fixedly connected with, and described filter screen 52 is made for stainless steel material, and aperture is the 20-100 order.Usually have some solid impurities as existence such as welding slags in refrigerant pipe; if remove not in time; can be to pipe wear; when serious, also can stop up; therefore; the design of filter member 5 can make connecting sleeve possess the function of filter, by the regular dismounting connecting sleeve, the solid impurity in refrigerant pipe can be removed.
Described outer ring 51 and the second groove 4 are interference fit, and interference fit can be fixed on filter member 5 in connecting sleeve body 1 closely.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has more been used the terms such as connecting sleeve body, boss, the first groove, the second groove, filter member, outer ring, filter screen, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
