Abstract
Disclosed is a liquid pump, comprising a tube connected by a hose; a piston is arranged in the hose, closely attached to the inner wall of the hose; the piston is close to one end of the tube, and an opening is arranged on the wall of the tube, close to the other end of the tube; and the opening is connected with a water flow switch. The liquid pump is characterized in that the piston is connected with one of the two plugsticks through screw caps and bolts, and the two plugsticks are connected through screw caps and bolts. When the liquid pump is used to pump liquid, one end of the piston of the tube is dipped into the liquid and the piston is pulled, then part of the area below the piston will become vacuumed and the liquid will move along with the piston, and when the piston reaches the other end, part of the plugsticks is dismantled from the joint of the plugsticks, then the plugstick will not be too long.
Description
Affiliated technical field
The utility model relates to a kind of liquid suction.
Background technique
At present, known piston type liquid suction stopper rod seems long sometimes.
Summary of the invention
In order to overcome the existing piston formula liquid suction stopper rod long deficiency that seems sometimes, the utility model provides a kind of liquid suction.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of liquid suction, comprise a pipe that has flexible pipe to connect, the piston of being close to hose inner wall is arranged in the flexible pipe, piston is near an end of pipe, opening is arranged on the tube wall, opening is near the other end of pipe, opening is connected with water switch, it is characterized in that: piston is connected in the mode of nut screw thread with the bolt thread combination with a stopper rod in two stopper rods, and stopper rod in two stopper rods is connected in the mode of nut screw thread with the bolt thread combination with another root stopper rod in two stopper rods.When extracting liquid, there is an end of piston to immerse in the liquid pipe, the pulling stopper rod, the piston below forms parital vacuum, and liquid is with piston motion, when the piston arrives the other end, pull down the part stopper rod from stopper rod and stopper rod connection part, stopper rod just can not seem long like this.
The beneficial effects of the utility model are: stopper rod can not seem long.
Description of drawings
Fig. 1 is the structural representation of liquid suction.
Among the figure: 1 flexible pipe, 2 pistons, 3 openings, 4 water switches, 5 stopper rods.
Embodiment
In the embodiment shown in fig. 1, a kind of liquid suction, comprise a pipe that has flexible pipe 1 to connect, the piston 2 of being close to flexible pipe 1 inwall is arranged in the flexible pipe 1, piston 2 is near an end of pipe, opening 3 is arranged on the tube wall, opening 3 is near the other end of pipe, opening 3 is connected with water switch 4, it is characterized in that: piston 2 is connected in the mode of nut screw thread with the bolt thread combination with a stopper rod 5 in two stopper rods, and stopper rod 5 in two stopper rods is connected in the mode of nut screw thread with the bolt thread combination with another root stopper rod 5 in two stopper rods.When extracting liquid, there is an end of piston 2 to immerse in the liquid pipe, pulling stopper rod 5, piston 2 belows form parital vacuum, and liquid is with piston 2 motions, when piston 2 arrives the other end, pull down part stopper rod 5 from stopper rod 5 and stopper rod 5 connection parts, stopper rod 5 just can not seem long like this.
