Abstract
The utility model discloses an air-conditioner connection pipe end cap, comprising a nut sleeve and a mandrel, wherein the nut sleeve is sleeved on a connection nut of an air-conditioner connection pipe; and the mandrel is used for positioning and connecting the connection nut and the connection pipe. An expansion pipe which is used for the insertion of the mandrel and expanded between the mandrel and internal threaded holes of the connection nut is arranged in the center of the nut sleeve. The technical solution is that a horn mouth at one end of the air-conditioner connection pipe is plugged by the nut sleeve which is sleeved on the connection nut outside the horn mouth; the connection nut is positioned at one end of the connection pipe by the mandrel; and the mandrel is inserted into the expansion pipe of the nut sleeve and is tightly plugged with the internal thread holes of the connection nut to fast connect the nut sleeve and prevent the nut sleeve from shedding. The utility model has the advantages that the air-conditioner connection pipe end cap is simple in structure, convenient to assemble, good in dust prevention effect, low in cost and the like.
Description
Technical field
The utility model relates to a kind of air conditioner connecting pipe plug.
Background technology
Publication number is that the patent documentation of CN2525417Y discloses a kind of detachable air conditioner tube connector, constitute by pipe, the insulating tube that is enclosed within the attaching nut at pipe both ends and is enclosed within pipe outside, the pipe two ends are all opened and are horn mouth, the attaching nut comprises the hex nut with internal thread and is positioned at the taper connection mouth of hex nut front end, inner conical surface in this connector cooperates socket with the horn mouth of pipe, for preventing that dust from raising in the inlet pipe, be screwed into a dustproof plug at the attaching nut place.When air-conditioning is installed, twist and remove dustproof plug, stretching pipe tightens to the attaching nut on the outer jointing of split-type air conditioner and promptly finishes installation.In the said structure, dustproof plug is threaded with the attaching nut, when making assembling air conditioner connecting pipe finished product, need the manually-operated plug that will prevent dust to be screwed on the attaching nut, be unfavorable for operating and enhancing productivity, and the dustproof plug of usefulness is a metallic article because great majority are threaded, so there is the cost problem of higher.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of air conditioner connecting pipe plug, has simple in structure, ease of assembly, good dustproof effect, low cost and other advantages.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of air conditioner connecting pipe plug, comprise that the nut overcoat on the attaching nut who is used to be sleeved on air conditioner connecting pipe positions the plug that be connected with the attaching nut with tube connector with being used for, described nut overcoat center is provided with and is used for inserting and the expansion tube of swelling between plug and attaching nut's internal thread hole for plug.
As preferably, described plug comprises the large diameter part that can match with expansion tube and can insert the small diameter part of tube connector end, the conical surface for matching with the horn mouth of tube connector end between large diameter part and the small diameter part.Accurate positioning like this, good dustproof effect.Further preferred, described large diameter part comprises first large diameter part and second large diameter part, and first large diameter part is connected with the described conical surface, and the front end edge circumference of first large diameter part is provided with projection, the rear end of first large diameter part is second large diameter part, and second large diameter part is thicker than first large diameter part.Packed and transported and the use of plug before installing for convenience is provided with first large diameter part, and plug and nut overcoat can fit together like this, the convenient use; Second large diameter part is set, when being used on air conditioner connecting pipe, plug being installed expansion tube is strutted the back swelling fully between plug and attaching nut's internal thread hole.Projection in the such scheme is preferably annular protrusion; Preferably be provided with positive stop lug boss, the convenient use in the rear end of above-mentioned second large diameter part.
As preferably, described plug is the hard moulding of hollow structure, helps injection mo(u)lding and reduces material cost.
As preferably, the elastomer that described nut overcoat and expansion tube are formed in one has dustproof preferably effect and installs firmly.In order further to guarantee dustproof effect, described nut overcoat be can the big envelope attaching nut hex nut nut overcoat partly, comprise end face and six sidewalls of covering hex nut.
The utility model is owing to adopted above technical scheme, the horn mouth of the end of employing nut overcoat shutoff air conditioner connecting pipe and the attaching nut who is enclosed within the horn mouth outside, adopt plug the attaching nut to be positioned at the end of tube connector, adopt plug to insert the expansion tube of nut overcoat and realize being connected fast and avoiding nut overcoat to come off, have simple in structure, ease of assembly, good dustproof effect, low cost and other advantages with the mode of attaching nut's internal thread hole jam-pack.
