Air conditioner connecting pipe component proposed by the present invention, refer to Fig. 1 to Fig. 5, in one embodiment, the air conditioner connecting pipe group
Part includes indoor set connecting tube 1, outdoor unit connecting tube 2, pipe joint 3, switching nut 4 and operating parts 5；Wherein,
One end of pipe joint 3 is fixedly connected with indoor set connecting tube 1, and outdoor unit connecting tube 2, which has, is sheathed on switching nut 4
Interior interface end 21, pipe joint 3 are connected through a screw thread mode and are connected on switching nut 4 to dock indoor set connecting tube 1 and room
Outer machine connecting tube 2；
Switching nut 4 is provided with the first motion thread and the first flange 42, and operating parts 5 is provided with and screwed with the first motion thread
The second motion thread and the end face that is abutted with the first flange 42, operating parts 5 can be positive or drive switching when forward rotating
Nut 4 screws with pipe joint 3, reverse or unscrew from switching nut 4 when rotating backward.
In the present embodiment, usually, indoor set connecting tube 1 has been completed to be connected with pipe joint 3 when dispatching from the factory, it is not necessary to sells
After install, and indoor set connecting tube 1 with pipe joint 3 by being welded to connect.Preferably, switching nut 4 is matched somebody with somebody with the screw thread of pipe joint 3
Close, to have the function that locking and sealing simultaneously.
Outdoor unit connecting tube 2 is rotatably ordinatedly connected with switching nut 4；The interlocking of the spiral of pipe joint 3 is in switching nut 4
It is interior, and coordinate with the switching self-locking of nut 4；
One end of the pipe joint 3 is fixedly connected with indoor set connecting tube 1, and the other end connects with switching nut 4 screw thread
Connect；For the interface end 21 of the outdoor unit connecting tube 2 between the switching nut 4 and the pipe joint 3, the other end stretches out institute
State outside switching nut 4.
Operating parts 5 annularly sets, is socketed in the periphery of switching nut 4, and to be driven in positive or forward rotation
Switching nut 4 screws with pipe joint 3, and prevents switching nut 4 from being rotated relative to pipe joint 3 in reverse or reverse rotation.
The inwall of the operating parts 5 is provided with the second motion thread, and second motion thread located at described with transferring outside nut 4
First motion thread of wall coordinates, to drive the switching nut 4 and the pipe joint 3 positive or forward screw, to institute
It is reverse or when reversely exerting a force to state operating parts 5, the relative nut 4 of transferring of the operating parts 5 rotates.
Air conditioner connecting pipe component of the present invention coordinates by using switching nut 4 with operating parts 5 to be socketed with pipe joint 3, is being needed
When locking switching nut 4 with pipe joint 3, forward direction or forward rotary operating member 5 are rotated with drive switching nut 4；Switching nut 4
After being locked with pipe joint 3, another mistake to or when reversely rotating operating parts 5, the nut 4 that relative can transfer of operating parts 5 rotate, and anti-rotation stop
Connected nut 4 is reverse with respect to pipe joint 3 or rotates backward, and has thus both reached the purpose of locking switching nut 4, has reached switching again
After nut 4 is locked with pipe joint 3, the purpose torn open by mistake is prevented.
Further, Fig. 4 and Fig. 5 is refer to, in one embodiment, second motion thread is to be arranged on operating parts 5
Multi-thread internal thread 51 on internal face, first motion thread are in the switching outside wall surface of nut 4 and described more to be arranged on
The multi-thread external screw thread 41 that line internal thread 51 is adapted to；
Please with reference to Fig. 1 to Fig. 3, described in the outside wall surface of switching nut 4 is provided with and abutted with the end face of the operating parts 5
First flange 42, the first flange 42 are set adjacent to indoor set connecting tube 1.
In the present embodiment, motion thread due to its lead angle it is larger, therefore, internal and external threads screw the frictional force to be formed
Smaller therefore reverse in operating parts 5 or when reversely rotating, frictional force torque is much smaller than switching nut 4 and the self-locking of pipe joint 3 therebetween
The reaction force of cooperation.When specifically assembling, operating parts 5 turns to when being abutted with the first flange 42, multi-thread external screw thread 41 and more
The cooperation of line internal thread 51 is only with transmission torque.
Further, multi-thread external screw thread 41 is two-wire external screw thread, and multi-thread internal thread 51 is two-wire internal thread.In the present embodiment
In, due to processing the double thread advantage of lower cost, therefore coordinated between operating parts 5 and switching nut 4 by double thread, can
To lift the cost advantage of the present embodiment air conditioner connecting pipe component.
Further, the internal face of switching nut 4 is provided with single line internal thread 43, and the outside wall surface of pipe joint 3 is provided with and list
The single external thread 31 that line internal thread 43 is adapted to.In the present embodiment, single thread processing is simple, and due to lead angle degree compared with
Small, the active force that self-locking coordinates after locking is big, therefore locks intensity height, it is also possible to realize preferable sealing function.
Further, it is circular plane that the end face of operating parts 5, which is connected to the binding face formed on the first flange 42,.Directly
Connected the end face of operating parts 5 and transmit torque with the abutting of the first flange 42 so that air conditioner connecting pipe modular construction is simple, saves
Manufacturing cost.
Further, the second flange 32 that the outside wall surface of pipe joint 3 abuts provided with the end face with nut 4 of transferring, second
Flange 32 is set adjacent to indoor set connecting tube 1.
In the present embodiment, after nut 4 of transferring screws in place with pipe joint 3, the second flange 32 abuts with switching nut 4,
Prevent the screw thread for axially excessively screwing in and damaging between switching nut 4 and pipe joint 3.
Preferably, for convenience of rotation or fixed pipe joint 3 is twisted, the second flange 32 circumferentially extends around the axis of pipe joint 3 and is in
Annular is set, and the outer peripheral face of the second flange 32 is more faceted pebbles.
Further, similarly, for convenience of rotation or fixed operation part 5 is twisted, the outer peripheral face of operating parts 5 is more faceted pebbles.
Further, interface end 21 is set towards the flaring of pipe joint 3, and the internal face of switching nut 4 has and interface end 21
The conical surface section 44 of adaptation, pipe joint 3 abut with the internal face of interface end 21.
In the present embodiment, specifically, the internal face of interface end 21 seals against with conical surface section 44, to realize that outdoor unit connects
Adapter 2 and the sealing of switching nut 4 coordinate and strengthened both axial bonding strengths.
Further, the end of the insertion of pipe joint 3 switching nut 4 is the conehead being adapted to interface end 21.In the present embodiment
In, conehead and the interface end 21 of pipe joint 3 coordinate, and increase both contacts area, thus can be further outside enhanced room
The sealing of machine connecting tube 2, and the internal face of the scratch interface end 21 of pipe joint 3 can be prevented.
The present invention also proposes a kind of air conditioner, and the air conditioner includes indoor set (not shown), outdoor unit (not shown), and
The air conditioner connecting pipe component of connection indoor set and outdoor unit, concrete structure reference above-described embodiment of the air conditioner connecting pipe component,
Because this air conditioner employs whole technical schemes of above-mentioned all embodiments, therefore at least there is the technical side of above-described embodiment
All beneficial effects caused by case, this is no longer going to repeat them.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this
Under the inventive concept of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in the scope of patent protection of the present invention.
