Use the service life.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of fresh wind port, have installation and
The advantages of convenient disassembly, and can ensure the service life of air port installation.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of fresh wind port, including air hose and air port, the air port includes the connecting tube being plugged in air hose and with connecting
The connected rain cover of pipe, the rain cover are located at outside metope, are provided with convex block in the connecting tube, the air hose inner wall upper edge its
Length direction offers the sliding groove slided for convex block and circumferential offer is rotated for convex block so that convex block is fastened on wind
Annular groove in pipe is provided with to limit the locating part that connecting tube rotates in air hose on the air hose.
So set, by pushing air port so that connecting tube is plugged into air hose, the mistake being inserted into connecting tube in air hose
Cheng Zhong, convex block slide on sliding groove, when air port is abutted against with metope, rotate rain cover so that convex block turns in annular groove
It is dynamic so that convex block misplaces with sliding groove, so that connecting tube along air hose is skidded off, cannot realize the axial limit of connecting tube
Position；
And coordinate the position-limiting action of locating part so that connecting tube cannot rotate in air hose, realize connecting tube
Circumferential limiting, under the cooperation of axial and circumferential limiting, realize fixation of the air port in air hose, have the installation and removal convenient
The advantages of, and convex block and locating part are all located in air hose, will not be damaged by environmental factor, can ensure air port installation
Service life.
Further preferably：The convex block is at least provided with two pieces, and the sliding groove is accordingly there are two settings.
So set, by setting at least two pieces of convex block, can under two pieces of cooperation, what connecting tube can be consolidated more
In annular groove, as soon as and it will not influence the axial limiting of connecting tube because of a piece convex block damage, protect to a certain extent
The axial limiting effect of connecting tube has been demonstrate,proved, and then ensure that the fixed effect in air port.
Further preferably：Locating part include be opened in the limiting slot on air hose inner wall, the spring in connecting tube,
And be connected with spring for the matched limited block of limiting slot, be provided in the connecting tube and be connected to limit with limited block
The separation member that position block is detached with limiting slot.
So set, during connecting tube is toward air hose grafting, limited block is abutted with air hose inner wall, and spring is in compression
State, at this point, limited block is located in connecting tube；
When the convex block in connecting tube rotates in annular groove, limited block one end contacts and with connection inside pipe wall in inner wall
Upper slip, when encountering limiting slot, limited block is pushed under the action of spring-return power in limiting slot, realizes connecting tube
Circumferential limiting；
When needing to detach air port and air hose, separation member is driven so that spring is in compressive state, and limited block is located at connection
In pipe, at this point, rotation rain cover so that convex block slides in annular groove, and face sliding groove, rain cover is pulled, at this point, convex
Block slides outward in sliding groove, and connecting tube is slided outward in air hose, that is, realizes the separation of entire air port and air hose.
Further preferably：The limiting slot is square, and the limiting slot is provided with arc side along the both sides of air hose circumferential direction.
So set, it is rectangular by setting, and coordinate along the both sides of air hose circumferential direction and be provided with arc side, convex block is in annular groove
During interior rotation, limited block is facilitated to enter in limiting slot.
Further preferably：The separation member include being slidably mounted in connecting tube be connected with limited block separating plate,
And it is connected to push separating plate so that the pushing plate that limited block is detached with limiting slot with separating plate.
So set, by pulling pushing plate, slided in connecting tube with separating plate so that limited block and then moves together
Dynamic, during separating plate slides, spring is compressed, and limited block is entered in connecting tube, and connecting tube is departing from all at this time
To the situation of limiting, it is possible to which, so that convex block rotates in annular groove, so as to be skidded off in sliding groove, the setting of separation member is convenient for
The dismounting of air port after installation.
Further preferably：Several tooth sockets, the rain-proof adjacent with tooth socket are offered in the pushing plate along its length
Cover is provided with the rack being meshed with tooth socket on side.
So set, when pushing separating plate due to pushing plate, spring is in compressive state, has certain restoring force, and
We set pushing plate to seek to the situation that connecting tube disengaging is circumferentially limited, and air port is then detached out of air hose, and at us
It is bad while hold pushing plate and rain cover when pulling the rain cover in air port, by the tooth socket and rain cover in pushing plate
Rack engagement, that is, realize pushing plate and rain cover being integrated temporarily, distinguished staff's separation to a certain extent
Air port and air hose.
Further preferably：The separating plate is set as arc.
So set, since connecting tube is in pipe, straight separating plate area occupied is larger, and the area used is also very
It is limited, by the setting of arc, the contact area with connecting tube can be increased, while solve the problems, such as that area occupied is big and makes
With the few situation of area.
Further preferably：Sealing ring is provided in the connecting tube.
So set, by the setting of sealing ring, the leakproofness between connecting tube and air hose can be increased.Prevent rain cover
Part water is penetrated into, interior is entered along connecting tube and air hose, plays the role of waterproof to a certain extent, can ensure air port
The service life of installation.
In conclusion the utility model having the beneficial effect that in contrast to the prior art：By the connection of convex block and annular groove,
It realizes the axial limiting of connecting tube, and coordinates the setting of limited block and limiting slot, realize the circumferential limiting of connecting tube, generally
Fixation of the air port in air hose is realized, installation and removal are also more convenient；And all structures are located at air hose and connecting tube
Between, it will not be effected by environmental factors, it can ensure the service life of air port installation.
