[0032] An embodiment of the present utility model provides a spray bar angle adjustment structure, which combines Figure 1-12 As shown, it includes a housing 1, a spray bar 2, a water supply pipe 3, and a nozzle seat 4 rotatably connected to the housing 1. One end of the spray bar 2 is communicated with the nozzle seat 4. The housing 1 is provided with a connecting member 5. One end of the water supply pipe 3 is communicated with the connecting member 5. The connecting member 5 is rotatably connected to the nozzle seat 4 and forms a sealed cavity for water supply circulation between the connecting member 5 and the nozzle seat 4. The sealed cavity communicates the water supply pipe 3 and the spray bar 2. When the spray bar 2 is rotated, the nozzle seat 4 rotates relative to the connecting member 5, and the positions of the connecting member 5 and the water supply pipe 3 remain fixed.

[0033] In the spray bar angle adjustment structure of the present utility model, by setting the spray bar 2 to be connected to the rotatable nozzle seat 4, setting the water supply pipe 3 to be connected to the connecting member 5 with a fixed position, and the nozzle seat 4 to be rotatably connected to the connecting member 5, when the user adjusts the angle of the spray bar 2, it will not drive the water supply pipe 3 to move or bend, and it is not easy to damage the water supply pipe 3. While meeting the different usage requirements of users, the spray gun can adapt to various usage environments, and at the same time, it is convenient for the folding and storage of the spray bar 2.

[0034] An installation groove 41 is recessed on the nozzle seat 4, and the installation groove 41 communicates with the spray bar 2. A communication cavity 51 is provided inside the connecting member 5, and the communication cavity 51 communicates the water supply pipe 3 and the installation groove 41.

[0035] As Figure 6 and 7 shown, the installation groove 41 is formed by inwardly recessing one end of the nozzle seat 4, the communication cavity 51 is formed by inwardly recessing one end of the connecting member 5, a part of the connecting member 5 is inserted into the installation groove 41, and one end of the connecting member 5 abuts against the installation groove 41. The water flow in the water supply pipe 3 passes through the communication cavity 51, flows into the installation groove 41, and then circulates into the spray bar 2 through the installation groove 41.

[0036] The spray bar angle adjustment structure further includes a sealing ring 6. An annular groove 52 suitable for installing the sealing ring 6 is provided on the outer side wall of the connecting member 5. The sealing cavity is formed by sealing between the installation groove 41 and the communication cavity 51 through the sealing ring 6.

[0037] As Figure 6 shown, the sealing ring 6 can be made of rubber material. The sealing ring 6 is used to seal the sealed cavity to prevent water leakage. At the same time, the sealing ring 6 can also play a damping role, so that the spray bar 2 can hover at any rotation angle.

[0038] The nozzle seat 4 includes a connecting portion 43 connected to the spray bar 2, and the connecting portion 43 communicates the installation groove 41 and the spray bar 2.

[0039] AsFigure 4 and 7 As shown in 7 , in this embodiment, a part of the connecting portion 43 is inserted into the spray bar 2 to make the connection structure more stable. The connecting portion 43 is a hollow rod-shaped structure, and the water flow in the spray bar 2 enters the communication cavity 51 through the connecting portion 43.

[0040] As Figure 4 shown, an annular flow groove 53 is recessed inwardly on the outer side wall of the connecting member 5, and a flow port 531 is formed on the flow groove 53. The flow port 531 communicates the communication cavity 51 and the installation groove 41.

[0041] As Figure 6 shown in the direction of Figure 6 , in this embodiment, the flow groove 53 is coaxially arranged with the annular groove 52, and the sealing ring 6 is arranged on the right side of the flow groove 53 to seal the sealing cavity formed by the cooperation of the flow groove 53, the communication cavity 51 and the installation groove 41. This setting can enable the water flow to flow into the nozzle seat 4 through the flow port 531 and then enter the spray bar 2 through the nozzle seat 4 without affecting the rotation.

[0042] A communication port 411 communicating with the spray bar 2 is provided in the installation groove 41, and the communication port 411 is in conduction with the flow groove 53 so that the communication port 411 is communicated with the flow port 531.

[0043] As Figure 6 shown, in this embodiment, when the nozzle seat 4 rotates, the communication port 411 rotates with the nozzle seat 4, and the rotation trajectory of the communication port 411 is adapted to the position of the flow groove 53. The water flow in the gap between the connecting member 5 and the nozzle seat 4 enters the spray bar 2 through the communication port 411, and at the same time, the water in the communication cavity 51 can also enter the spray bar 2 through the cooperation of the communication port 411 and the flow port 531.

[0044] The housing 1 includes a left housing 11. A first installation portion 111 suitable for installing the connecting member 5 is provided on the left housing 11, and a limiting port 112 is formed on the first installation portion 111.

[0045] As Figure 9 and 10 shown, in this embodiment, a part of the connecting rod 54 is inserted into the water supply pipe 3 to make the connection structure more stable. The connecting rod 54 is a hollow rod-shaped structure, and the limiting port 112 is adapted to the connecting rod 54. This setting can fix the position of the connecting member 5 to prevent the connecting member 5 from rotating when the nozzle seat 4 rotates.

[0046] The housing 1 includes a right housing 12. One side of the nozzle holder 4 close to the right housing 12 is convexly provided with a mounting shaft 42. The right housing 12 is provided with a second mounting portion 121 adapted to mount the mounting shaft 42, and the mounting shaft 42 is rotatably connected to the second mounting portion 121.

[0047] As Figure 11 and 12 shown, in this embodiment, the second mounting portion 121 is provided at one end of the left housing 11 close to the spray bar 2. The vertical cross-section of the mounting shaft 42 is circular, and the vertical cross-section of the second mounting portion 121 is also circular. The mounting shaft 42 is inserted into the second mounting portion 121 and rotates in the second mounting portion 121. Both ends of the nozzle holder 4 are hingedly connected to the left housing 11 and the right housing 12 respectively.

[0048] The nozzle holder 4 is convexly provided with a rotating block 44. The housing 1 is provided with a first limiting portion 113 and a second limiting portion 114, and the first limiting portion 113 and the second limiting portion 114 are respectively limited at the beginning and end of the rotation path of the rotating block 44.

[0049] As Figure 7 、 10 、12 shown, both the left and right sides of the nozzle holder 4 are convexly provided with rotating blocks 44. The rotating blocks 44 are cylindrical in shape, and the rotating blocks 44 on both the left and right sides of the nozzle holder 4 are located on the same axis. The first limiting portion 113 and the second limiting portion 114 are provided on the left housing 11, and the rotating block 44 on the left side of the nozzle holder 4 cooperates with the first limiting portion 113 and the second limiting portion 114. The right housing 12 is provided with a third limiting portion 122 and a fourth limiting portion 123, and the rotating block 44 on the right side of the nozzle holder 4 cooperates with the third limiting portion 122 and the fourth limiting portion 123.

[0050] When the user rotates the spray bar 2, the nozzle 2 drives the nozzle holder 4 to rotate. When the rotating block 44 on the left side of the nozzle holder 4 rotates, it will be engaged and collided with the first limiting portion 113 or the second limiting portion 114 to remind the user to reach the limit position. When the rotating block 44 on the right side of the nozzle holder 4 rotates, it will be engaged and collided with the third limiting portion 122 or the fourth limiting portion 123 to remind the user to reach the limit position.

[0051] As Figure 1 and 2 shown, the rotation angle range of the spray bar 2 is 0 - 170°. The spray bar 2 can be adjusted at multiple angles according to the user's needs, making it more convenient to use and also more convenient for folding and storage.
