Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, specifically to a fan-shaped nozzle adjustment assembly. Background Technology

[0002] As a key component in modern agricultural irrigation, industrial cleaning, spraying, and fire fighting, the core function of fan-shaped sprinklers is to disperse water flow into a clearly defined fan-shaped spray through a specific flow guiding structure to achieve efficient coverage. However, existing technologies generally adopt a fixed flow guiding surface design, that is, a single spray angle is preset through mold injection or machining. Before operation, a specific angle sprinkler needs to be pre-installed according to the needs of the scenario. A single replacement takes 5-10 minutes, and it is necessary to maintain a multi-specification sprinkler inventory, which leads to increased management costs. Utility Model Content

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3 As shown, this embodiment discloses a fan-shaped nozzle adjustment assembly, including a first adjusting member 1 and a second adjusting member 2. The first adjusting member 1 has a first connecting portion 11 for connecting accessories and a second connecting portion 12 coaxially connected to the first connecting portion 11. The second adjusting member 2 has a fourth connecting portion 22 for connecting water pipes and a third connecting portion 21 coaxially connected to the fourth connecting portion 22. The third connecting portion 21 is rotatably disposed inside the second connecting portion 12. The second connecting portion 12 has a first elastic bead 3 arranged radially. The outer peripheral wall of the third connecting portion 21 has a plurality of grooves 2111 that cooperate with the first elastic bead 3 at equal angular intervals along the circumference. The accessory can be a fan-shaped nozzle or a spray bar connected to the fan-shaped nozzle. By rotating the second adjusting member 2, the elastic bead is compressed and retracted. When the fan-shaped nozzle rotates to a suitable angle, the first elastic bead 3 re-cooperates with the corresponding groove, realizing the adjustment of the spray angle of the fan-shaped nozzle. There is no need to temporarily replace the fan-shaped nozzle, improving work efficiency and saving costs. The first connecting part 11 and the second connecting part 12 are integrally injection molded, and the third connecting part 21 and the fourth connecting part 22 are integrally injection molded.

[0020] like Figure 2 As shown, the third connecting portion 21 includes a first step 211, a second step 212, and a third step 213 with successively decreasing diameters. The second connecting portion 212 has a first through hole 124 that mates with the first step 211, a second through hole 125 that mates with the second step 212, and a third through hole 126 that mates with the third step 213. The outer peripheral wall of the first step 211 has the groove. The diameter of the first step 211 is smaller than the diameter of the fourth connecting portion 22. This three-step structure achieves precise axial positioning and prevents liquid leakage.

[0021] like Figure 2 As shown, the outer peripheral wall of the second step 212 is provided with an annular groove 2121, and the third connecting part 21 is provided with a second elastic bead 4 in the radial direction. The second elastic bead 4 cooperates with the annular groove 2121 and provides radial preload to prevent the third connecting part 21 from coming off. The cooperation between the second elastic bead 4 and the annular groove 2121 allows the second connecting part 12 and the third connecting part 21 to rotate in a cooperative manner.

[0022] like Figure 2 and 3As shown, in this embodiment, the second connecting part 12 is radially provided with a first mounting hole 121 for mounting the first elastic bead 3, and the first mounting hole 121 communicates with the first through hole 124; the second connecting part 12 is provided with a second mounting hole 122 for mounting the second elastic bead 4, and the second mounting hole 122 communicates with the second through hole 125. The first elastic bead 3 and the second elastic bead 4 have the same structure. The first elastic bead 3 includes a screw 31, a spring, and a ball 32 connected in sequence. The screw 31 is threaded into the first mounting hole 121 and the second mounting hole 122 respectively. The first spring bead and the second spring bead are existing technologies, that is, the screw 31 is a hollow screw 31, one end of the spring is located inside the screw 31, and the other end of the spring is connected to the ball 32. The operator can adjust the tightness between the ball 32 and the groove by tightening or loosening the screw 31, thereby adjusting the ease with which the second mounting part rotates relative to the third mounting part.

[0023] like Figure 2 As shown, in this embodiment, the first connecting part 11 has a liquid outlet 111 communicating with the third through hole 126. The outer peripheral wall of the third step 213 is provided with multiple sealing rings 5, and the outer wall of each sealing ring 5 abuts against the inner wall of the third through hole 126. The sealing rings 5 ​​can be made of fluororubber.

[0024] like Figure 1 As shown, in this embodiment, the sealing ring 5 has a V-shaped opening 51 on its end face facing the liquid outlet 111. The V-shaped opening 51 does not extend to the other end of the third step 213. When liquid is ejected from the liquid outlet and flows back to the sealing ring 5, the V-shaped opening 51 is enlarged by the impact of the water flow, further abutting against the inner wall of the third through hole 126, achieving a better sealing effect. The opening angle of the V-shaped opening 51 can be 30°~60°.

[0025] like Figure 1 As shown, the outer peripheral wall of the second connecting part 12 is provided with a plurality of protrusions 123 spaced apart along the axial direction. The design of the protrusions 123 facilitates the user's rotation of the second connecting part 12.

[0026] This embodiment also includes an extension rod. The outer peripheral wall of the first connecting part 11 is provided with an external thread 112, and the inner peripheral wall of the extension rod is provided with an internal thread that mates with the external thread 112. The extension rod also has a liquid outlet hole 111 inside. A fan-shaped nozzle can be connected to the end of the extension rod away from the first connecting part 11, which is suitable for long-distance spraying or coating. The first connecting part 11 can also be directly connected to the fan-shaped nozzle.
