Abstract
The utility model relates to an air-conditioner repairing tool and provides an air-leakage preventing and liquid filling tube for air-conditioner repairing. The air-leakage preventing and liquid filling tube for comprises an oil filling tube and a leakage prevention device, the oil filling tube is arranged on the upper portion of the leakage prevention control device, a connection tube is arranged on the lower portion of the leakage prevention control device, and a movable connection nut is arranged on the connection tube. An ejector pin, an upper positioning washer and a lower positioning washer, and a rotating rod are arranged inside the leakage prevention control device, the ejector pin is positioned by the upper positioning washer and the lower positioning washer so that the ejector pin is not eccentric, a first gear is arranged on the middle-and-upper portion of the ejector pin, and a second gear is arranged on the rotating rod. When the rotating rod rotates, the first gear and the second gear are meshed to move the ejector pin up and down, and a rotating handle is arranged at one end of the rotating rod. When one side of a vertical face of the leakage prevention control device controls the rotating rod, the ejector pin can move up and down; when the ejector pin moves downwards, the ejector pin can extend out of the connection tube. Seal rubber cushions are arranged at the upper end and the lower end of the connection tube, on the leakage prevention control device and a seal nut, and on the oil filling tube and the leakage prevention control device.
Description
Technical field
The utility model relates to a kind of air-conditioning maintenance instrument, especially relates to a kind of air-conditioning maintenance leakproof gas-liquid filler pipe.
Background technique
Usually, large because relating to pressure when the pressurize test of air conditioner coolant system or filling refrigerant (refrigerant can be gaseous state or liquid state), and by the manual rotation nut, when opening simultaneously the maintenance spool, part gas or liquid are spilt.When operation inconvenience, possible frostbite operator.
Summary of the invention
The purpose of this utility model is for the existing deficiency of existing air-conditioning maintenance filling gas-liquid, provides a kind of air-conditioning maintenance that can avoid leakage phenomenon during gas-liquid of annotating with leakproof gas-liquid filler pipe.
The utility model is provided with oil filling pipe and leak-proof control device, described oil filling pipe is located at leak-proof control device top, the leak-proof control device bottom is provided with connecting tube, connecting tube is provided with the flexible connection nut, leak-proof control device inside is provided with thimble, up and down locating washer and turn bar, locating washer is positioned thimble up and down, make thimble not eccentric, the thimble upper position is provided with the 1st gear, the turn bar is provided with the 2nd gear, and when the turn bar rotated, the 1st gear and the engagement of the 2nd gear moved up and down thimble, turn bar one end is provided with the turn handle, when at leak-proof control device facade one side control turn bar, thimble can move up and down, when thimble moves down, can from connecting tube, stretch out two ends about connecting tube, leak-proof control device and sealing nut place, oil filling pipe and leak-proof control device place are equipped with seal rubber pad.
Described leak-proof control device and connecting tube upper end can be threaded connection with, and leak-proof control device and sealing nut can be threaded connection with, and leak-proof control device and oil filling pipe can be threaded connection with.
When using the utility model, the pipe end that refuels connects fuel feeding meter, the connecting tube that the leak-proof control device bottom is provided with connects air-conditioning high low pressure maintenance valve, can come by the rotatable handle of leak-proof control device side stretching out and withdrawal of thimble in the control gear, the spool in the air-conditioning high low pressure maintenance valve is opened or closed; After first nut being connected, open again the maintenance spool, or after closing first the maintenance spool, again nut is removed, realized freely to open or close between air conditioner coolant system and the external pipe, thereby avoided leakage phenomenon.
