Description of the Related Art A sprayer used for spraying an insecticide or the like has a plurality of nozzle pipes having different diameters connected to each other so that it can expand and contract. The structure of a conventional telescopic nozzle pipe of this kind is shown in FIG. The connecting body 6 has a large diameter nozzle pipe 4b fixed to its mounting hole 6a with a screw or an adhesive. A clamp 7 and a cap 8 are fitted to the small diameter nozzle pipe fitted to the pipe 4b. Then, after sliding the small-diameter nozzle pipe 4a to a required length, the cap 7 is screwed into the threaded portion 6b at the tip of the connecting body 6 to tighten the clamp 7 so that the diameter is larger than that of the large-diameter nozzle pipe. Fix the small nozzle pipe. 9 is an O-ring.

合部には過大な接着力を必要としていた。In the method of fixing the nozzle pipe by tightening the screw as described above,
The hands are slippery when opening and closing the cap, and the operation of expanding and contracting the nozzle pipe is troublesome. Since the sprayer handles liquids such as chemicals and water, the connecting portion gets wet and the above-mentioned problem becomes remarkable. Further, since the tightening torque of the cap varies depending on the user, when the cap is strongly tightened and then loosened, torque is applied to the joint between the large diameter nozzle pipe and the connector. Therefore, an excessive adhesive force is required at the joint.

的とする。The present invention solves the problems as described above, and is easy to expand and contract, and the torque is not directly applied to the joint between the pipe and the connecting body, so that a strong adhesive force is not required. An object is to provide an easy telescopic nozzle pipe.

係止部材とを有するものである。A telescopic nozzle pipe of the present invention comprises a connecting body which fixes the tip of a large diameter nozzle pipe and is provided with a sliding portion of a small diameter nozzle pipe which fits into the large diameter nozzle pipe. And a locking member that is held by the connecting body and that frictionally fixes the small diameter nozzle pipe to the connecting body by rotating the lever.

かかりにくくなる。In the present invention, since the nozzle pipe is fixed by operating the lever, the nozzle pipe can be easily fixed without slipping unlike the screw type. The nozzle pipe is fixed by frictional force, but since the lever principle is used, a large frictional force can be obtained with a small operating force.
Further, since torque is applied on the circumference around the fulcrum of the locking member, torque is less likely to be applied on the circumference around the nozzle pipe.

A pump portion is housed in the main body case 1, the chemical liquid in the tank 2 is sucked up by the pump portion, and sprayed from the nozzle 5 through the hose 3 and the plurality of nozzle pipes 4. The pipe portion can be expanded and contracted by the connecting portion 10, so that the pipe portion can be sprayed freely in low places and high places. 2 and 3 show the connecting portion. This connecting part 10
Is composed of a connecting body 11 and a locking member 12.

するための係止部材１２を設けている。The connecting body 11 is made of a columnar body having a substantially elliptical cross section, and is provided with a screw hole 13 at an eccentric position for screwing the end portion of the large diameter nozzle pipe 4b into communication therewith. A hole 14 is provided for sliding the small diameter nozzle pipe 4a. In addition, a notch 15 communicating with the hole 14 is provided on the side part so as to be opened, and a pin 16 pivotally provided in parallel with the hole 13 is fixed in the notch 15 for fixing the small diameter nozzle pipe. The locking member 12 is provided.

とする。The locking member 12 is rotated around the pin 16 by operating the lever portion 17, and the peripheral surface thereof is a curved surface portion 18. As shown in FIG. 4, the curved surface portion has a maximum eccentricity such that the maximum eccentricity point b has a diameter such that the locking member 12 presses the small diameter nozzle pipe 4a in the hole 14 and slightly deforms the pipe. Before and after the point, the diameter is gradually reduced. Then, when the locking member 12 is rotated counterclockwise and the lever portion 17 abuts the side surface of the coupling body 11, the diameter of the curved surface portion 18 in contact with the pipe 4b at the point c is such that The size is such that can be pressed and fixed. Also, rotate clockwise to contact the pipe a
After passing the point, the diameter of the peripheral surface portion is set to a size apart from the pipe.

れる。Since the connecting member 11 and the locking member 12 are constructed as described above, the small diameter nozzle pipe 4a is slid in the state shown in FIG. 4A to adjust the length, and then the lever portion. 1
By operating 7 to rotate counterclockwise to the state of (d), the curved surface portion c point of the locking member comes into contact with the side surface of the pipe,
The pipe can be fixed by frictional force. That is, when the locking member 12 is rotated counterclockwise, first, the point a of the curved surface portion comes into contact with the pipe to press and fix it, but if the lever portion is released as it is, the curved surface portion The diameter gradually increases in the counterclockwise direction, and then the reaction occurs in the clockwise direction, and the lever part is also returned. However, since the lever portion is rotated counterclockwise against the reaction to move beyond the curved surface portion b point, the diameter of the curved surface portion is gradually reduced counterclockwise. The lock member 12 is also fixed by the action of the lever portion coming into contact with the side surface of the connecting body 11.

ルパイプとの接合部に強い接着力を必要としない。Further, when the small diameter nozzle pipe 4a is moved again and the expansion / contraction operation is performed, the lever portion 17 is rotated clockwise so that the maximum eccentricity point b and the contact point a of the curved surface portion are exceeded, whereby the diameter is reduced. The fixation of the small nozzle pipe is released. In the above operation, torque is applied to the curved surface portion 18 of the locking member 12 centering on the pin 16, so that torque is less likely to be applied on the pipe circumference centering on the nozzle pipe. Therefore, torque is less likely to be applied to the joint between the connecting body and the large-diameter nozzle pipe, so that a strong adhesive force is not required at the joint between the connecting body and the large-diameter nozzle pipe.

に構成されている。In the above embodiments, the locking member is rotatably held by the connecting body, and has a curved surface portion and a lever portion including a portion contacting the small diameter nozzle pipe on the peripheral surface thereof. The portion is configured so that the contact portion of the curved surface portion with the pipe is locked to the connecting body at a rotating position beyond the maximum eccentric point.
