[0031] In order to make the purpose, technical scheme and advantages of the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0032] In order to solve the technical problem that the angle of the rotated three-way elbow neck needs to be manually maintained, the utility model provides a water spraying device, which can fix the rotated water spraying device to a set angle.

[0033] It should be noted that the water spraying device is used for but not limited to a water spraying cannon and the like, and in order to facilitate the description, the water spraying device is applied to the water spraying cannon in the utility model, and the principle of the water spraying device applied to other types of equipment is substantially the same as that applied to the water spraying cannon, and thus is not described here.

[0034] Please refer to Figure 1 , Figure 1 Fig. 1 is a structural schematic view of a water spraying device according to an embodiment of the utility model, and the water spraying device comprises a water inlet assembly 1, a water spraying assembly 2 and a limiting assembly 3.

[0035] The working principle of the water spraying device is that water is introduced through the first water inlet of the water inlet assembly 1, flows into the water spraying assembly 2 through the water outlet, and is finally sprayed through the water spraying port of the water spraying assembly 2; when it is necessary to adjust the setting angle of the water spraying assembly 2 to adjust the water spraying angle of the water spraying port, the water spraying assembly 2 is controlled to rotate relative to the water inlet assembly 1, and after rotation, the limiting assembly 3 is in the limiting state, so that the limiting assembly 3 fixes the water spraying assembly 2 to the water inlet assembly 1, and it is not necessary to manually maintain the setting angle of the rotated water spraying assembly 2.

[0036] It should be understood that the water inlet assembly 1 can be a water inlet pipe, a water inlet connector, a water inlet seat and the like, and specifically, as shown in Figure 1 one of the embodiments, the water inlet assembly 1 is a tee pipe, the tee pipe is formed by two pipe bodies perpendicular to each other, has one first water inlet and two water outlets.

[0037] It should be understood that the water spraying assembly 2 can be a water spraying pipe, a pipe nozzle and the like.

[0038] It should be understood that the limiting assembly 3 can adopt a limiting screw, the limiting screw is threadedly connected with the water spraying assembly 2 and abuts against the water inlet assembly 1, can fix the rotated water spraying assembly 2 at any position, and the limiting assembly 3 can also be a buckle and the like.

[0039] The limiting screw fixes the water spraying assembly 2 by clamping the water inlet assembly 1, and realizes the limiting by abutting, but the abutting limiting is easy to loosen, and thus, as shown in Figure 5As shown in the drawings, in one embodiment, the limiting assembly 3 is connected to either the water inlet assembly 1 or the water spraying assembly 2 and can be clamped with or separated from the other one.

[0040] In this embodiment, the limiting of the water spraying assembly 2 relative to the water inlet assembly 1 is achieved by clamping, which is less likely to loosen than abutting and can more stably fix the rotated water spraying assembly 2.

[0041] Since clamping is adopted, two structures clamped with each other are needed. In order to fix the rotated water spraying assembly 2 at multiple positions, as shown in Figure 1 and Figure 3 In one embodiment, the water inlet assembly 1 and / or the water spraying assembly 2 forms multiple fixed points 1a, which are distributed along the circumference of the water outlet. The limiting assembly 3 can cooperate with the fixed points 1a to be in the limiting state and can be separated from the fixed points 1a to be in the released state.

[0042] In this embodiment, the rotated water spraying assembly 2 is fixed by clamping the limiting assembly 3 with the fixed points 1a. Since there are multiple fixed points 1a, the water spraying assembly 2 has multiple fixed angles to choose from.

[0043] It should be understood that the fixed points 1a can be inwardly recessed grooves or outwardly protruding protrusions.

[0044] In order to achieve the clamping and separation of the limiting assembly 3 and the fixed points 1a, as shown in Figure 1 and Figure 3 In one embodiment, one of the water inlet assembly 1 and the water spraying assembly 2 forms the fixed points 1a, and the limiting assembly 3 includes a connecting piece 31 and a clamping piece 32. The connecting piece 31 connects the other one of the water inlet assembly 1 and the water spraying assembly 2, and the clamping piece 32 is slidingly connected to the connecting piece 31 and can slide close to and away from the fixed points 1a. Specifically, in one embodiment, the water spraying assembly 2 forms the fixed points 1a, and the connecting piece 31 connects the water spraying assembly 2.

[0045] In this embodiment, the clamping piece 32 is slid to enable the clamping piece 32 to clamp or separate from the fixed points 1a. When the clamping piece 32 clamps the fixed points 1a, the clamping piece 32 is in the limiting state. When the clamping piece 32 separates from the fixed points 1a, the clamping piece 32 is in the released state.

[0046] Moreover, the clamping piece 32 and the fixed points 1a are clamped and separated by sliding, which is convenient.

[0047] It should be understood that the connecting piece 31 can be a connecting strip, a connecting fastener, etc., and the clamping piece 32 can be a clamping block, a clamping pin, etc.

[0048] In order to drive the clamping piece 32 to clamp the fixed point 1a, as shown in one of the embodiments, Figure 5 the limiting assembly 3 further comprises an elastic piece 33 connected to the connecting piece 31 and the clamping piece 32.

[0049] In the embodiment, the elastic piece 33 can push the clamping piece 32 to clamp the fixed point 1a. When it is needed to separate the clamping piece 32 from the fixed point 1a, the clamping piece 32 is slid in a direction away from the fixed point 1a, so that the clamping piece 32 extrudes the elastic piece 33 and is separated from the fixed point 1a. When the clamping piece 32 is released, the clamping piece 32 is slid in a direction close to the fixed point 1a under the pushing of the elastic piece 33 and clamps the fixed point 1a.

[0050] It should be understood that the elastic piece 33 can be a spring, an elastic block, an elastic strip, etc.

[0051] It should be understood that the water spraying assembly 2 and the water inlet assembly 1 can be rotationally connected by means of a rotating sleeve, a rotating shaft, a rotating pipe, etc. Specifically, as shown in one of the embodiments, Figure 1 and Figure 4 the water spraying assembly 2 is rotationally sleeved on the water inlet assembly 1 and is sealingly connected to the water inlet assembly 1.

[0052] In the embodiment, the water spraying assembly 2 is rotationally sleeved on the water inlet assembly 1, so as to rotationally connect the water spraying assembly 2 and the water inlet assembly 1. The water spraying assembly 2 is sealingly connected to the water inlet assembly 1, so as to avoid water leakage from the rotational connection between the water spraying assembly 2 and the water inlet assembly 1.

[0053] It should be understood that the water spraying assembly 2 can be arranged on a water pipe on one side of the water inlet assembly 1. Specifically, as shown in one of the embodiments, Figure 1 and Figure 2 the water spraying assembly 2 comprises two connecting pipes 21 and a spray pipe 22. One end of each of the two connecting pipes 21 is rotationally sleeved on the two sides of the water inlet assembly 1 opposite to each other and is in communication with the water outlet. The connecting pipe 21 is sealingly connected to the water inlet assembly 1. The spray pipe 22 is in communication with the other end of each of the two connecting pipes 21.

[0054] In the embodiment, the two connecting pipes 21 can inject water flow into the spray pipe 22, so as to increase the water flow entering the spray pipe 22. The connecting pipe 21 is rotationally sleeved on the two sides of the water inlet assembly 1 opposite to each other, so that the connecting pipe 21 cannot slide away from the water inlet assembly 1 along the axis of the water outlet and can rotate relative to the water inlet assembly 1.

[0055] If two connecting pipes 21 are directly sleeved on the two sides of the water inlet assembly 1, the connecting pipes 21 cannot be separated from the water inlet assembly 1, which is not convenient for assembly and disassembly. Therefore, as shown in the embodiment, the water spraying assembly 2 further comprises two sleeves 23, which are rotatably sleeved on the two sides of the water inlet assembly 1 and are sealingly connected with the water inlet assembly 1. The connecting pipes 21 are detachably connected with the sleeves 23 and are rotatably and sealingly connected with the water inlet assembly 1 through the sleeves 23. It should be understood that the connecting pipes 21 and the sleeves 23 can be detachably connected through bolts, screws, buckles and the like. Figure 4

[0056] In the embodiment, the water inlet pipe is rotatably sleeved on the water inlet assembly 1 through the sleeve 23, realizing the rotatable sleeving between the water inlet pipe and the water inlet assembly 1. When assembling, the sleeve 23 is sleeved on the water inlet assembly 1, and then the connecting pipes 21 are connected with the water inlet assembly 1, so that the connecting pipes 21 can be sleeved on the water inlet assembly 1 and can be disassembled.

[0057] It should be understood that the sleeves 23, the connecting pipes 21 and the water inlet assembly 1 can be rotatably sealed through sealing strips, sealing rings and the like.

[0058] The connecting piece 31 can be connected with any one of the spray pipe 22, the connecting pipe 21 and the water inlet assembly 1. Specifically, as shown in the embodiment, in one embodiment, the connecting piece 31 comprises a connecting portion 311 and a sleeve 312. The connecting portion 311 is detachably connected with the two connecting pipes 21. The sleeve 312 is connected with the connecting portion 311. The clamping piece 32 is slidingly arranged in the sleeve 312 and is arranged relative to the fixed point 1a. The elastic piece 33 connects the sleeve 312 and the clamping piece 32. Figure 2

[0059] It should be understood that by connecting the connecting portion 311 with the two connecting pipes 21, the connecting of the connecting portion 311 and the connecting pipes 21 is realized. By arranging the sleeve 312 and slidingly inserting the connecting piece 31 into the sleeve 312, the sliding connection of the clamping piece 32 and the connecting piece 31 is realized.

[0060] It should be understood that the connecting portion 311 and the connecting pipe 21 can be detachably connected through bolts, screws and buckles. By connecting the connecting portion 311 with the two connecting pipes 21, the two ends of the connecting portion 311 are fixed, so that the clamping piece 32 and the sleeve 312 are more stable and have higher structural strength.

[0061] When adjusting the angle of the water spraying assembly 2, in order to avoid that the clamping piece 32 limits the rotation of the water spraying assembly 2, as shown in the embodiment, the clamping piece 32 is provided with a through hole 321, and the connecting piece 31 is provided with a protrusion 3111. The protrusion 3111 is arranged in the through hole 321. Figure 2 Figure 3 ​​​As shown in the drawings, in one of the embodiments, the inner wall of the sleeve 312 is cylindrical, and the sleeve 312 is provided with a notch groove 312a on one side, and the clamping piece 32 is rotatably inserted into the sleeve 312, and the limiting assembly 3 further comprises a limiting pin 34, which is slidably connected to the clamping piece 32 and can be slidably inserted into the notch groove 312a.

[0062] During the rotation of the clamping piece 32, the clamping piece 32 is driven to slide away from the fixed point 1a, and the clamping piece 32 drives the limiting pin 34 to slide away from the notch groove 312a, and then the clamping piece 32 is rotated, and the elastic piece 33 pushes the clamping piece 32 to move towards the fixed point 1a, but at this time the limiting pin 34 abuts against the sleeve 312, which can limit the rotation of the clamping piece 32 towards the fixed point 1a, avoiding the influence of the clamping piece 32 on the rotation of the water spraying assembly 2; when the water spraying assembly 2 is rotated to a predetermined position, the clamping piece 32 is rotated, so that the limiting pin 34 is aligned with the notch groove 312a, and at this time the limiting pin 34 can be slidably inserted into the notch groove 312a, and the clamping piece 32 can be slidably inserted into the fixed point 1a.

[0063] In order to facilitate the pushing and rotating of the clamping piece 32, specifically, Figure 3 and Figure 5 As shown in the drawings, in one of the embodiments, the limiting assembly 3 further comprises a handle 35 connected to the end of the clamping piece 32 away from the fixed point 1a.

[0064] In order to avoid the sleeve 312 sliding along the axis relative to the limiting assembly 3, for this purpose, Figure 4 As shown in the drawings, in one of the embodiments, the water inlet assembly 1 forms a limiting structure 1b, which is arranged between the two sleeves 312 and abuts against one of the sleeves 312.

[0065] In this embodiment, by arranging the limiting structure 1b, the limiting structure 1b can abut against the sleeve 312 and limit the sleeve 312, so as to avoid the sleeve 312 sliding relative to the water inlet assembly 1.

[0066] It should be understood that the limiting assembly 3 can be a limiting protrusion, a limiting ring, a limiting pin 34, etc.

[0067] It should be understood that, the fixed point 1a can be a recess recessed inwardly, or a protrusion protruding outwardly. Specifically, in one of the embodiments, the limiting structure 1b is a limiting ring coaxial with the water outlet, and the fixed point 1a is a recess formed by the limiting ring recessed inwardly, and the clamping piece 32 is in sliding fit with the recess.

[0068] In order to drive the connecting pipe 21 and the water spraying pipe to rotate relative to the water inlet assembly 1, for this purpose, Figure 1 and Figure 2As shown, in one of the embodiments, the water spraying device further comprises a handle 4, which is connected with the connecting pipe 21 and / or the spray pipe 22.

[0069] In the embodiment, the handle 4 is arranged, and the handle 4 is used to pull the connecting pipe 21 and the spray pipe 22 to rotate relative to the water inlet assembly 1.
