Structural improvement of water spray gun

The present invention relates to a structure of a water spray gun, in particular to an innovative type designer who uses a dial-type positioning member to control the fixed state of the water jet head to prevent the spray head from being loosened when it is adjusted.

According to the use of water spray guns for flowers, gardening and other work places, it is quite common. The common way to use water pipes is to connect one end of the water spray gun to make the water flow through the water spray gun and change the water column type (such as fog, Columns and other variants), in order to facilitate the user to spray irrigation for different flower species; in the current structure of the water spray gun on the market, usually has a grip portion for the user to hold the hand, formed in the grip The reduced diameter pipe portion at one end of the portion, the water outlet opening through the reduced diameter pipe portion, and the water spray adjusting head seat fitted to the reduced diameter pipe portion, and the user can be provided by rotating the water spray adjusting head seat The rotating part is used to control the water column type; the author of this creation is to improve the research on the positioning structure of the conventional water spray adjusting head and grip parts.

In the conventional water spray adjusting the positioning structure of the head base and the grip portion, most of the positioning grooves are arranged inside the water spray adjusting head, and positioning bumps are arranged at corresponding positions of the reduced diameter pipe portion, when the water spray adjusting head seat When the reducing tube portion is sleeved, the positioning protrusion is locked into the positioning groove by the rotation method to make the water spray adjusting head seat reach the positioning, however, when the user rotates the rotating portion of the water spray adjusting head seat, It often causes the water spray adjusting head seat to be interlocked to cause the positioning groove to be disengaged from the positioning protrusion, thereby causing the problem that the water spray adjusting head seat is loose. In addition, the positioning convex block and the positioning groove are used under long-term rotation adjustment. It will also result in poor clamping effect due to wear and tear, which will also cause the lack of water leakage and even water leakage.

For guiding, the first positioning portion 51 can be aligned from the introduction portion 53 into the second positioning portion 52, and the first positioning portion 51 can be made by dialing the dial-type positioning member 30. The snap-in card is positioned in the engagement section 54.

As shown in FIG. 3, it is one of the embodiments of the present invention, that is, the outer portion of the connecting portion 21 is provided with four sets of first anti-rotation portions 41 and second positioning portions 52, which constitute the inner side of the water outlet 13 Four sets of second anti-rotation portions 42 are provided, and the inner side of the ring portion 31 of the dial-type positioning member 30 is also provided with four sets of first positioning portions 51, but is not limited to such a matching number; 3 to 5, wherein the dialing portion 32 of the dial-type positioning member 30 is in the form of a protruding rod or a flange (in the presently, the protruding rod type), and protrudes beyond the adjustment limiting slot 14, In order to facilitate the user to move.

As shown in FIG. 6, wherein the dialing type positioning member 30 is provided with a dialing portion The 32-series is in a spaced-apart tooth shape, and the dialing portion 32 can correspond to the adjustment limiting slot 14 so that the user can toggle the toothed dial portion 32 to switch the fixed state of the water jet head 20. .

As shown in FIG. 7 , it is another embodiment of the present invention, wherein the outer portion of the connecting portion 21 is provided with a set of first anti-rotation portions 41 and two sets of second positioning portions 52, and the inner side of the water outlet 13 Only one set of second anti-rotation portions 42 is provided, and only one set of first positioning portions 51 is provided inside the loop portion 31 of the dial-type positioning member 30, and further, a lead-in section of one of the second positioning portions 52 is provided. The engaging portion 54 and the first anti-rotation portion 41 are disposed at different positions of the connecting portion 21. In this embodiment, when the connecting portion 21 is pivoted to the water outlet 13, the first and the first 2. The rotation preventing portions 41 and 42 are prevented from being engaged with each other to prevent the water jet head 20 from being steered, and the cooperation relationship between the first and second positioning portions 51 and 52 can prevent the water jet head 20 from being disengaged forward. The axial positioning action is the same as the foregoing, and will not be described in detail in this part.

With the above-mentioned structure and composition design, the operation of the present invention is explained as follows: as shown in FIGS. 3 to 5, when the nozzle portion 21 of the water spray head 20 is pivoted to the water outlet 13, the first passage is passed. The water outlet 13 allows the first and second anti-rotation portions 41 and 42 to be in a male-female relationship with each other (in this embodiment, the embodiment of the groove-fitted projection), and then passes through the dial-type positioning member 30. The inside of the loop portion 31 is such that the first positioning portion 51 can be aligned from the lead-in portion 53 into the second positioning portion 52, and the first positioning portion 51 can be embedded by dialing the dial-type positioning member 30. The card is positioned in the engaging portion 54, so that the water jet head 20 is in a fixed limit state, so that the water spray head 20 can maintain a stable fixed position state under long-term use, and the water spray head 20 is fixed regardless of how the water spray portion 22 is rotated and adjusted. The state is unshadowed, and when the user needs to disassemble the water jet head 20, the first positioning portion can be made only by dialing the dial portion 32 in the opposite direction. The clutch 51 is disengaged from the engaging portion 54, so that the water jet head 20 is detachable, thereby making the water jet head 20 more convenient and quick to disassemble.

Efficacy description: The facts that enhance the effectiveness of this creation are as follows:

The "Structural Improvement of Water Spray Gun" disclosed in this work mainly uses the water spray gun body, the water jet head, the dial-type positioning member, the anti-rotation unit and an innovative structure to prevent the disengagement unit from co-constructing. According to the prior art, the first positioning portion of the anti-disengagement unit can be inserted and positioned in the engaging portion by using the dial portion of the dial-type positioning member, so that the water jet can be prevented. The axial positioning function of disengaging and falling forward means that the fixed or disassembled state of the water jet head is switched by dialing the dial-type positioning member, so when the user rotates and adjusts the water spray portion, The fixed state of the water jet head is not affected. Therefore, the water jet head can be stably and fixedly located in the main body of the water spray gun without being detached for a long time, thereby achieving the practical utility of improving the practicability of the product and greatly improving the convenience of use.
