Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
The following specific examples of the utility model is only the explanation to the utility model, is not new to this practicality
The limitation of type, those skilled in the art can as needed make without creativeness the present embodiment after reading this specification
The modification of contribution, but as long as all being protected by Patent Law in the right of the utility model.
A kind of suspension and support of central air-conditioning discharge pipe, as shown in Figure 1, including sunpender 1 and cross-arm 2,1 lower end of sunpender is screw thread
Face, cross-arm 2 pass through sunpender 1, and by sunpender 1 tightening nut cross-arm 2 is abutted with discharge pipe so that cross-arm 2 with hang
Bar 1 connects.
As depicted in figs. 1 and 2,2 both ends of cross-arm are fixedly installed shaft 3, and the first unilateral bearing 4 is arranged on shaft 3, the
The inner ring level of one unilateral bearing 4 is slidably connected on shaft 3, and outer ring is fixedly connected with gear 6, is fixedly connected on sunpender 1
The vertical rack 5 being meshed with gear 6, shaft 3 are parallel to the teeth of vertical rack 5, and locking piece is provided on cross-arm 2 to limit
First unilateral bearing 4 it is vertically movable.
The locking piece includes：Level is slidably connected to the second unilateral bearing 7 on shaft 3；The outer ring of second unilateral bearing 7
On be fixedly installed inserted link 8, the limit hole 9 mating with inserted link 8 is provided on the outer ring of the first unilateral bearing 4；First is single
Rotation direction to 7 outer ring of bearing 4 and the second unilateral bearing is reversed each other.
When the suspension and support of discharge pipe is installed, cross-arm 2 is pushed up so that the gear 6 on the first unilateral bearing 4 and vertical tooth
5 engagement rotation of item, and due to the self-locking of the first unilateral bearing 4, be in contact with the bottom surface of discharge pipe when moving to it on cross-arm 2
During, cross-arm 2 will not be fallen downwards, and the first unilateral bearing 4 plays pre-determined bit to the connection of cross-arm 2 and sunpender 1 at this time
Effect, operating personnel need not hold in the palm cross-arm 2 on one side when connecting cross-arm 2 with sunpender 1, on one side between sunpender 1 and cross-arm 2
Connection is installed, easy to operate, time saving and energy saving, and security performance is high.
When cross-arm 2 is abutted with the bottom surface of discharge pipe, the second unilateral bearing 7 is pushed, and rotates the outer of the second unilateral bearing 7
It is unidirectional to limit first that circle so that the limit hole 9 on inserted link 8 and the first unilateral bearing 4 on the second unilateral bearing 7 coordinates grafting
Bearing 4 slides vertically so that the effect of the pre-determined bit of the first unilateral bearing 4 is more preferable.
Inserted link 8 is evenly equipped with more along the outer ring of the second unilateral bearing 7, and limit hole 9 is uniformly distributed along the outer ring of the first unilateral bearing 4
Have multiple, guide surface 14 has been both provided on limit hole 9.
The second unilateral bearing 7 is rotated, the cooperation grafting of inserted link 8 and limit hole 9 is convenient for, and guide surface 14 is set so that inserting
Bar 8 is easier to be inserted into limit hole 9, increases stability when inserted link 8 coordinates grafting with limit hole 9.
As shown in figure 3, being both provided with fixing piece between the first unilateral bearing 4 and the second unilateral bearing 7 and shaft 3 to limit
First unilateral bearing 4 and the second unilateral bearing 7 are slided along the level of 3 length direction of shaft.
Above-mentioned fixing piece includes：It is fixedly installed on the fixed block 10 at 3 both ends of shaft；Spiral shell on the fixed block 10 of 3 one end of shaft
Line is connected with the first screw rod 11, and the first screw rod 11 and 4 inner ring of the first unilateral bearing are rotatablely connected；Above-mentioned fixing piece further includes：Axis
The second screw rod 12 being threadedly coupled with 7 inner ring of the second unilateral bearing is plugged on the fixed block 10 of 3 other end of bar.Second one-way shaft
When holding 7 and being fixedly connected with the fixed block 10 on 3 one end of shaft, it is connected with the elastic component in compressive state between the two, the bullet
Property part be specially compression spring 13, when between fixed block 10 and the second unilateral bearing 7 spacing relation release after, in the elastic force of compression spring 13
Under effect, the inserted link 8 on the second unilateral bearing 7 and limit hole 9（See Fig. 2）It is mating more stablize, securely.
The first screw rod of turn 11, and push the first unilateral bearing 4 is horizontal on shaft 3 to slide, it can be achieved that the first one-way shaft
It holds gear 6 on 4 and the quick separating of vertical rack 5 and engages, realize quick separating and the connection of cross-arm 2 and sunpender 1；Direction
Second screw rod 12 pushes the second unilateral bearing 7 so that being threadedly coupled between the second unilateral bearing 7 and the second screw rod 12, limits
The horizontal sliding of second unilateral bearing 7, makes it not interfere with the engagement rotation of gear 6 and vertical rack 5 so that 2 edge of cross-arm
It is mobile on the length direction of sunpender 1 more to stablize.
Shown in Fig. 1, cross-arm 2 is provided with rubber sheet gasket 15 on the contact surface of discharge pipe.Rubber sheet gasket 15 makes
The case where contact surface of discharge pipe and cross-arm 2 is not easy to deform, leaks out so as to cause discharge pipe.
Specific working mode：When needing to carry out the installation between cross-arm 2 and sunpender 1, cross-arm 2 is passed through into sunpender 1, at this time
Gear 6 is meshed with vertical rack 5, cross-arm 2, gear 6 and 5 engagement rotation of vertical rack is pushed up, when cross-arm 2 and discharge pipe
Bottom surface when abutting, press the second unilateral bearing 7, and rotate the second screw rod 12 so that the second screw rod 12 and the second unilateral bearing
It is disengaged between 7, the second unilateral bearing 7 is under the action of the elastic force of compression spring 13, along shaft 3 towards the first unilateral bearing 4
Level sliding, the outer ring for being rotated further by the second unilateral bearing 7 makes inserted link 8 coordinate grafting with limit hole 9, at this point, cross-arm 2 and sunpender
It is fixedly connected between 1.
When needing to dismantle between cross-arm 2 and sunpender 1, the first screw rod 11 is rotated, and drive first is unidirectional
Bearing 4 is along the horizontal sliding of shaft 3 so that gear 6 is staggered with vertical rack 5, takes out cross-arm 2 downwards, you can completes cross-arm 2 and hangs
Dismounting separation between bar 1.
When carrying out the installation between cross-arm 2 and sunpender 1, cross-arm 2 is pushed up, the self-locking of the first unilateral bearing 4 makes
Obtaining cross-arm 2 will not move down, and play the role of pre-determined bit for the installation between cross-arm 2 and sunpender 1, then pass through the second unilateral bearing
The rotation of 7 the first unilateral bearings 4 of limitation so that the pre-determined bit effect of the first unilateral bearing 4 is more preferable.
