Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained on the premise of creative work is not made, belongs to what the present invention was protected
Scope.
In a particular embodiment of the present invention, as shown in Figure 1 to Figure 2, cable dress is led under water the invention particularly discloses one kind
Put, including pulley 1, pulley spindle 2, pulley support 3, retaining mechanism 4, swing seat 5, fixing axle 6, upper fixed seat 8 and lower fixed seat
9, fixed seat 8 and lower fixed seat are fixed on profile about 9；
The two ends of swing seat 5 are separately fixed on fixed seat 8 and lower fixed seat 9, and the quantity of fixing axle 6 is
Two, two fixing axles 6 are setting up and down and parallel with profile, and one end of two fixing axles is each attached to
In the swing seat 5, the other end is separately fixed on fixed seat 8 and lower fixed seat 9,
The pulley 1 is assembled on pulley support 3 by pulley spindle 2, and the outer rim of the pulley 1, which is provided with, is used for hawser motion
Groove, the pulley support 3 is connected by rotary pin shaft 7 with swing seat 5, and the pulley support 3 is carried out around rotary pin shaft 7
Lower upset, flip angle is around 7 upward 55 ° of rotary pin shaft and downward 55 °；
The quantity of the retaining mechanism 4 is two groups, is separately positioned on the two ends of swing seat 5, the retaining mechanism 4 is used for
Pulley support 3 after upset is locked in the swing seat 5.When pulley support 3 is swung up 55 °, retaining mechanism 4 will be sliding
