Description

  The present invention relates to a structure of a grip type watering nozzle. It is a grip-type watering nozzle structure that is particularly easy to operate.

  The structure of the conventional watering nozzle is a watering device that is operated by hand and has different watering effects depending on the water pressure and the size of the watering hole diameter. Regardless of whether the control lever of the watering nozzle is the front lever type or the rear lever type, the user must hold the control lever with his / her finger, and the watering operation or the amount of water is controlled by adjusting the force of the finger. However, the operation of gripping the control lever with a finger faces a reaction force that occurs when the control lever is gripped. The longer the time that the user holds the control lever, the more fatigued the hand is and the tighter feel that affects the efficiency and smoothness of the watering. Therefore, the related industry has developed a watering nozzle design in which the control lever press has a positioning effect. After the user grips the control lever, the control lever can be positioned with the attached hook, and the user's hand can be controlled without much force, and the labor-saving purpose can be easily achieved. Furthermore, it is possible to change the amount of water at the same time using changing the positioning position with the control lever with the hook. However, there are still unsatisfactory parts when looking at the conventional structure described above. The main causes are as follows.

(1) When the watering nozzle is fixed in a watering state, the control lever must be positioned by operating the hook with the other hand while holding the control lever with one hand. It is very inconvenient in operation, and if the other hand has something else, it is difficult to control the watering operation effectively, so it is impossible to combine the effects of labor saving and convenience of use.

(2) The sprinkling nozzle control lever has functions to start sprinkling and control the sprinkling amount, and the sprinkling amount can be changed by adjusting the gripping force, but it becomes difficult to control the sprinkling amount, and the same sprinkling amount is smooth each time. Because it is difficult to adjust to the practicality, practicality is reduced.
Therefore, in light of the above, the inventor has designed the above-mentioned objectives carefully after careful experience in the development and design of correlated products for many years, and obtained the present invention full of practicality after careful evaluation. It was.

  The present invention solves the disadvantages existing in the prior art and provides a structure of a grip type watering nozzle.

  The present invention provides a structure of a grip type watering nozzle. The first object of the present invention is to fix the press-fitting cover at the position where water sprinkling starts by sliding the protrusion of the U-shaped fastener into the positioning tank along the introduction slope of the V-shaped block and coupling the protrusion to the positioning tank. Thus, the user can achieve the purpose of watering without having to hold down the press-fit cover for a long time. If you want to stop watering, press the press-fit cover once more, the protrusion of the U-shaped fastener will move away from the positioning tank of the V-shaped block, and slide to the lower part of the V-shaped block by guiding the stop block. Can be released along the lead-out slope of the V-shaped block, and the operation of fixed watering can be released, so that the effect of labor saving and convenience of use can be achieved whether or not watering is repeated quickly.

  The second object of the present invention is that the hook portion of the rotary knob can be interlocked with the interlocking port of the in-situ tube, so that the amount of overlap of the flow port and the opening of the connecting tube can be changed by rotation of the in-situ tube. Therefore, since the amount of water flowing from the connecting tube side to the front tube side can be controlled, the amount of water sprayed on the watering head side can be adjusted effectively, and the practicality is improved.

  The third object of the present invention is that the metering member is provided with an annular first groove on the surface of the connecting pipe, the control pipe is coupled with a C-shaped lock, and the C-shaped lock is fitted into the first cut and the first groove. As a result, the connection of the connecting pipe and the control pipe is formed. Further, the control pipe is provided with an axial groove at one opening of the flow hole, and the metering member has an axial rib protruding from the connecting pipe, and is coupled to the axial groove of the control pipe by the axial rib. As a result, it is formed that the control pipe and the metering member are quickly connected, and an effect of preventing rotation between the metering member and the control pipe is achieved.

And the connecting pipe 21 is separated. At this time, the water flow flows out from the inside of the valve tube 30 to the water discharge hole 32 and enters the metering member 20 through the connecting pipe 21, so that the watering operation of the watering head 28 can be performed. At the same time, when the press-fit cover 40 is pressed, the positioning member 43 approaches the control tube 10, and the protrusion 141 of the U-shaped fastener 14 slides toward the positioning tank 443 along the introduction slope 441 of the V-shaped block 44. . When the hand is released from the press-fit cover 40, the protrusion 141 is coupled to the positioning tank 443 so that the press-fit cover 40 is fixed at the position where the water spray is started, and the user can continue without pressing the press-fit cover 40. The purpose of continuing to sprinkle can be achieved. If it is desired to stop the water supply, the press-fit cover 40 is pushed again, the protrusion 141 of the U-shaped fastener 14 moves away from the positioning tank 443 of the V-shaped block 44, and slides down to the lower part of the V-shaped block 44 by the guidance of the stop block 431. . In addition, when the hand is released from the press-fit cover 40, the projecting portion 141 is slid along the lead-out slope 442 of the V-shaped block 44, and the watering operation can be canceled, and whether or not to spray is quickly and repeatedly switched. It has the effect of saving labor and convenience during use.
