Affiliated technical field
The utility model relates to detachable air conditioner, particularly the connecting tube assembly between such air conditioner indoor machine and the outdoor unit.
Background technique
At present, connecting tube assembly between known split-type air conditioner air conditioner indoor machine and the outdoor unit, comprise one thick one thin two copper pipes, the stop valve of outdoor unit, the liquid in-out connecting port of indoor set and joint locking fitting, above-mentioned blister copper pipe (tracheae) or thin copper pipe (liquid pipe) outdoor unit stop valve and the indoor set liquid in-out port corresponding with it are tightly connected by realizations such as joint locking fitting such as locking nuts, because each corresponding joints is taked conical surface more, the locking nut that is positioned at copper pipe end one side cooperates precession to tighten up with the thread section of corresponding joints, forcing the joint conical surface to probe into the corresponding port of copper pipe and form the horn mouth attitude seals, though this connection fit system can be realized good being tightly connected, but, how to reduce its user cost and become the technical problem of being badly in need of solution because the cost of copper pipe is higher.There is a kind of improved technological scheme to arise at the historic moment, promptly take one section copper pipe, one section aluminum pipe section and one section copper pipe to join successively to form metal tube to replace above-mentioned pure copper tube, this metal tube both can utilize the metallic character of the copper pipe of linkage section in connection procedure, again owing to take the lower aluminium matter pipe of cost than long one section in the middle of this pipe, therefore user cost has obtained certain reduction, but aspect processing and fabricating, there is suitable difficulty, the production and processing cost is higher, manufacturing efficiency is low, and this metal tube is still continued to use the aforementioned technical approach that is tightly connected.
Summary of the invention
Task of the present utility model is to solve the above-mentioned technical problem that prior art exists, novel connecting tube assembly between a kind of air conditioner indoor and outdoor machine is provided, one thick one thin two metal tubes in this connecting tube assembly, have at least one to take aluminium matter pipe, help reducing production costs, also can satisfy the requirement that is tightly connected.
Its technical solution is:
Novel connecting tube assembly between a kind of air conditioner indoor and outdoor machine, the advancing/fluid connecting port and joint locking fitting of stop valve, indoor set that comprises one thick one thin two metal tubes, outdoor unit, above-mentioned crude metal pipe or thin metal pipe outdoor unit stop valve and the indoor set liquid in-out port corresponding with it are realized being tightly connected by the joint locking fitting, have at least one to be aluminium matter pipe in above-mentioned crude metal pipe and the thin metal pipe.
Above-mentioned crude metal pipe and thin metal pipe are aluminium matter pipe.
Above-mentioned aluminium matter pipe, having at least place, a connecting port to be provided with by self tube wall pier in two connecting port presses the outer rim that forms to protrude in the ring part of tube wall, the open sides of ring part is the annular flat end face, with its joint that directly connects or with being provided with and its suitable planar end surface that docks with transition holding element between the corresponding joints that it directly connects at it.
Above-mentioned aluminium matter pipe, two place, connecting port is equipped with by self tube wall pier and presses the outer rim that forms to protrude in the ring part of tube wall.
Above-mentioned ring part, its ring body section become opening semicircle arcuation or U word shape inwardly.
Above-mentioned joint locking fitting, comprise be nested with the connecting port inside tube on one's body locking nut and be arranged on thread section on the corresponding joints, cooperate with thread section by locking nut and realize docking of connecting port and corresponding joints.
The ring part double as at place, above-mentioned connecting port is the spacing stop part of locking nut.
The inner sealing surface of above-mentioned locking nut is the planar base surface suitable with the ring part connecting part.
The utility model beneficial effect is: the usual copper pipe that uses of crude metal pipe or thin metal pipe in the prior art is replaced with aluminium matter pipe, can reduce greatly and produce and maintenance cost.Aluminium matter pipe is taked subordinate's technical approach: be provided with by self tube wall pier at the place, connecting port and press the outer rim that forms to protrude in the ring part of tube wall, the open sides of ring part is the annular flat end face, with its joint that directly connects or with being provided with and its suitable planar end surface that docks with transition holding element between the corresponding joints that it directly connects at it, the annular flat end face of aluminium matter pipe joins with the planar end surface that docks of joint etc. during connection, and cooperate precession to tighten up with the thread section of its corresponding joints by joint locking fitting such as locking nut, force two planar end surfaces closely to contact and realize being tightly connected, this kind technical approach, distortion when ring part can be guaranteed its stressed sealing is no more than scope, can not cause harmful deformation to aluminium matter pipe ring shape planar end surface, can repeatedly repeat to connect and use, satisfy seal request; Overcome the problem that can't avoid directly taking prior art in the production practices process, to run into effectively: promptly because aluminium matter pipe is softer, it is connected use once with corresponding joints after, directly formed bell mouth shape in corresponding port by expansion, no longer be suitable for repeating for the second time to connect, disassemble a posterior restoration aluminium matter pipe and just may scrap and abandon, cause waste or the like.
