Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As Figure 1-Figure 2, the specific structure of the utility model are as follows: a kind of cooling tower door lock assembly, it includes maintenance door
2, being horizontally disposed on the inside of the maintenance door 2 has U-shaped frame 9；Being horizontally disposed on the U-shaped frame 9 has telescopic push rod 8；It is described to push away
Restraining position ring block 10 is fixedly installed on bar 8；The compressed spring 11 for pushing down push rod 8 is arranged on the push rod 8；The compression bullet
Spring 11 is located in U-shaped frame 9；8 tail end of push rod is provided with two parallel gag lever posts 12；Vertically intert in the maintenance door 2
There is screw rod 6；6 both ends of screw rod are fixed in maintenance door 2 by nut 3；It is provided with and pushes away between the nut 3 and maintenance door 2
Power bearing 5；6 two ends of screw rod are provided with ball handle 4；It is located at 2 medial surface one end of maintenance door on the screw rod 6 to be arranged
There is the driving lever 13 perpendicular to screw rod 6；13 upper end of driving lever is stuck between two gag lever posts 12.
Preferably, the screw rod 6 is arranged below push rod 8.
Preferably, the positioning hole 14 for installing gag lever post 12 is evenly arranged on the push rod 8 along axial direction；The limit
12 screw thread of bar is arranged in positioning hole 14.
Preferably, small bearing 7 is provided on the gag lever post 12 of 8 caudal end of push rod.
The specifically used principle of the utility model:
Rotating ballhead handle 4 drives screw rod 6 to rotate, and screw rod 6 drives driving lever 13 to swing, and 13 upper end of driving lever is stuck in two limits
In the bar 12 of position, therefore to will drive push rod 8 elastic for the swing of driving lever 13, realizes and locks and open.
Compressed spring 11 on push rod 8 can make in knuckle ball head handle 4, and push rod 8 is forwardly inserted doorframe automatically
Upper latching maintenance door.
Thrust bearing 5 is provided between nut 3 and maintenance door 2, so that user can guarantee in rotating ballhead handle 4
The smooth stable rotation of screw rod 6, fluency is very good, and small bearing 7 also can be set on gag lever post 12, so that driving lever 13 is pushed down
