Description

Sprinkler with adjustable impact stroke

The present invention relates to an impact sprinkler, and more particularly to an innovative structure of an impact sprinkler with adjustable impact stroke.

The principle of the impact sprinkler being able to automatically turn and change the direction of the water spray during the water spraying process is mainly achieved by utilizing the impact force of the hammer blade generated by the elastic swing back after being pushed away by the water column.

In order to adjust the turning speed, the industry has introduced a method of adjusting the impact force by adjusting the extension arm of the hammer. However, this method has been found to have some problems and disadvantages in actual application experience. In terms of accuracy, the hammer itself swings and rebounds at different angles each time under different water column pressures, and is also affected by the field environment (such as gusts, temperature and humidity, etc.) during the rebound process, which may cause the inertial force generated at each impact moment to be different. This makes it difficult for the impact sprinkler to accurately adjust and control its water output.

Even though the above variables can ensure that the differences are small, the more important problem is that the main components of the impact sprinkler are usually made of plastic injection molding. After the finished product is assembled, due to factors such as the difference in shrinkage rate, bending deformation rate and assembly error of each component, it is known that even if the model specifications of each impact sprinkler are the same, the basic adjustment structure itself has deviations, and there is still a lack of any adjustable mechanism. As a result, it is known that it is difficult to accurately adjust and control the water output results of the impact sprinkler (such as the turning speed or the time required for one circle). This is indeed an important technical issue worthy of attention and breakthrough by the relevant industry.

The main purpose of the present invention is to provide a sprinkler with adjustable impact stroke. The technical problem to be solved is to explore and innovate a new type of impact sprinkler structure with a more ideal and practical performance.

Based on the above-mentioned purpose, the technical features of the present invention for solving the problem mainly lie in that the impact stroke adjustable sprinkler comprises: a main body, including a water inlet pipe assembly end, a positioning bracket part and a water spout connected to the water inlet pipe assembly end, wherein the water inlet pipe assembly end is in a rotatable state; an impact guide frame, which is pivotally assembled to the positioning bracket part of the main body in a swingable state, and the impact guide frame comprises a rotating seat part, a hydraulic propulsion plate and a connecting arm between the rotating seat part and the hydraulic propulsion plate, the hydraulic propulsion plate is connected to the front side of the rotating seat part and extends to the front interval of the water spout, and the hydraulic propulsion plate is defined according to the swinging and resetting directions to form a swinging side and a return side. side, so that when water flows out of the water nozzle, the hydraulic push plate can be pushed to drive the impact guide frame to swing toward the swing-out side, and a reset component is assembled between the rotating seat part and the positioning bracket part, so that the swing movement of the impact guide frame has an automatic restoring force toward the return side; a swing limit component is protruded on one side of the positioning bracket part of the main body, and the swing limit component is made to correspond to the swing-out side, and the swing limit component must be located on the corresponding swing movement circular path of the impact guide frame; a stroke control means is used to adjust the relative distance between the swing limit component and the impact guide frame, thereby constituting that the swing movement stroke of the impact guide frame is in an adjustable state.

The main effect and advantage of the present invention is that the relative distance between the swing limit component and the impact guide frame can be adjusted through the stroke control means, thereby adjusting the swing motion stroke of the impact guide frame, so that the user can accurately adjust and control the water output result of the sprinkler. In addition, for the deviation of the basic structure of the sprinkler itself, the present invention provides a mechanism for fine-tuning correction, which is particularly practical and progressive and has better industrial utilization benefits.

Please refer to Figures 1 to 5, which are preferred embodiments of the impact stroke adjustable sprinkler of the present invention. However, these embodiments are only for illustrative purposes and are not limited to this structure in patent applications.

The impact stroke adjustable sprinkler comprises the following structures: a main body 10, which comprises a water inlet pipe assembly end 11, a positioning bracket part 12 and a water spout 13 connected to the water inlet pipe assembly end 11, wherein the water inlet pipe assembly end 11 is in a rotatable state; an impact guide frame 20, which is pivotally assembled to the positioning bracket part 12 of the main body 10 in a swingable state, and the impact guide frame 20 comprises a rotating seat part 21, a hydraulic propulsion plate 22 and a hydraulic pressure plate 23 between the rotating seat part 21 and the hydraulic pressure plate 24. The hydraulic push plate 22 is connected to the front side of the rotating seat 21 and extends to the front of the water spout 13. The hydraulic push plate is defined to form a swinging side D1 and a returning side D2 according to the swinging and resetting directions, so that when the water spout 13 discharges water, the hydraulic push plate 22 is pushed to drive the impact guide frame 20 to swing toward the swinging side D1, and a resetting member 30 is assembled between the rotating seat 21 and the positioning bracket 12. (such as torsion springs, inclined guide surfaces, etc.), so that the swinging movement of the impact guide frame 20 has an automatic restoring force toward the return side D2; a swing limiting component 40 is protruded on one side of the positioning bracket portion 12 of the main body 10, and the swing limiting component 40 corresponds to the swing-out side D1, and the swing limiting component 40 must be located on the corresponding swinging movement circular path of the impact guide frame 20; a stroke adjustment means is used to adjust the relative distance between the swing-out side D1 of the swing limiting component 40 and the impact guide frame 20, thereby constituting the swinging movement stroke of the impact guide frame 20 to be adjustable.

As shown in FIG. 1 and FIG. 2 , in this example, the stroke control means is achieved by combining the swing limiter 40 with the positioning bracket 12 in an adjustable position (such as by rotating or switching gears). In this example, a corresponding engaging claw 51 and a plurality of spaced positioning slots 52 are provided between the swing limiter 40 and the positioning bracket 12. The engaging claw 51 can be aligned and engaged with different positioning slots 52 as the position of the swing limiter 40 is adjusted (see the difference between FIG. 4 and FIG. 5 ).

With the above-mentioned structural assembly and technical features, the present invention discloses a sprinkler with adjustable stroke. In practical application, as for the preferred embodiment, if the user adjusts the position of the swing limiter 40 to a position with a smaller stroke range as shown in FIG. 4, then when the water from the water outlet 13 pushes the hydraulic push plate 22 to drive the swing guide frame 20 to generate a swinging motion, it will be blocked when it swings to the position of the swing limiter 40. Limit, this limiting action is accurate every time (Note: the adjustment type of adjusting the hammer extension arm to change the swing impact force is known, but it cannot be accurately adjusted because the inertial force is different each time); in addition, assuming that the user adjusts the azimuth adjustment of the swing limit component 40 to a position with a larger stroke range as shown in Figure 5, it can relatively allow the impact guide frame 20 to obtain a swing motion stroke limit effect with a larger angle.

As shown in Figures 6 to 8, in this example, the stroke control means is achieved by assembling an adjustment bolt 60 at a location of the impact guide frame 20B, and the adjustment bolt 60 includes an assembly section 61 and an abutment end 62, wherein the assembly section 61 is adjustably assembled on the impact guide frame 20B, and the convex extension of the abutment end 62 can be adjusted to change, so that the swinging motion stroke of the impact guide frame 20B can be limited by the abutment.

In the embodiment disclosed in the previous paragraph, the impact guide frame 20B (in this example, the connecting arm 23 thereof) has a screw hole 24, and the assembly section 61 of the adjustment bolt 60 is configured as a stud to be screwed into the screw hole 24, thereby forming a spiral adjustment of the protrusion extension, so as to adjust the relative distance between the impact guide frame 20B and the swing limiter 40B in this example. In addition, the adjustable protrusion extension of the abutment top 62 can also be specifically realized by replacing different lengths of the adjustment bolts or ratchet clamping advance and retreat adjustment.

As shown in Figures 9 to 11, in this example, the stroke control means is achieved by assembling a control bolt 60C at one location of the swing limiter 40C. The control bolt 60C includes a set section 61C and an abutting end 62C. The set section 61C is adjustable and assembled on the swing limiter 40C. The convex extension of the abutting end 62C can be adjusted and changed, so that the swing motion stroke of the impact guide frame 20C is abutted and limited.

In the embodiment disclosed in the previous section, the swing limit member 40C has a screw hole 41, and the assembly section 61C of the adjustment bolt 60C is configured as a stud to be screwed into the screw hole 41, thereby forming a spiral adjustment of the convex extension. In addition, the convex extension of the top end 62C can also be adjusted by replacing different length adjustment bolts or ratchet clamping advance and retreat adjustment.

Through the above-mentioned structural assembly and technical features, the impact stroke adjustable sprinkler disclosed in the present invention can mainly adjust the relative distance between the swing limit component and the impact guide frame through the stroke adjustment means, thereby adjusting the swing motion stroke of the impact guide frame, so that the user can accurately adjust the water output result of the sprinkler (such as swing speed, time, etc.), and for the deviation of the basic structure of the sprinkler itself (such as the error caused by the deformation of plastic molding), the present invention also provides a fine-tuning correction mechanism and has its practicality and advantages.
