DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-4 , a spraying device with an adjustable spraying range, including a spraying machine body 1, a spraying gun body 2 is installed at one end of the spraying machine body 1, a spray head 21 is provided at one end of the spraying gun body 2, and a pushing block 6 is installed in a limited way on one side of the spraying gun body 2, and a plurality of installation grooves 11 are opened on the spraying gun body 2. A base 51 is rotatably installed in the installation groove 11 through a rotating shaft 9. A paint spraying frame 5 is connected to one side of the base 51, and a guiding wedge block 7 is provided on the base 51. The guiding wedge block 7 is in pressing contact with the pushing block 6.

[0021] Furthermore, a support cylinder 3 is fixedly installed in the middle of the bottom end of the spraying gun body 2. A threaded hole is provided inside the support cylinder 3, and an adjusting screw rod 4 is installed inside the support cylinder 3 through threaded connection.

[0022] Furthermore, a plurality of transverse grooves are provided on the inner wall of the push block 6 to fit the convex strips 12 provided on the spraying gun body 2, and the push block 6 is slidably installed on the outer wall of the spraying gun body 2 by means of the convex strips 12 for limiting.

[0023] Furthermore, a connecting block 61 is installed at the bottom of the push block 6. One end of the connecting block 61 is rotatably installed with an adjusting screw rod 4, and the other end of the adjusting screw rod 4 passes through the support cylinder 3.

[0024] Furthermore, a base 51 and a jetting frame 5 are fitted and installed inside the installation groove 11. The jetting frame 5 is arranged on both sides of the nozzle 21, and an air intake nozzle 8 is provided on one side of each jetting frame 5. The air intake nozzle 8 is used to connect to an external gas and enable the jetting frame 5 to jet air, so as to realize the basic spraying function.

[0025] Furthermore, a spring 10 is installed on one side inside the installation groove 11, and the other end of the spring 10 is connected to one side of the inner wall of the base 51.

[0026] In this embodiment, the spraying machine body 1, the spraying gun body 2, and the nozzle 21 constitute a basic spraying device to realize basic spraying operations. At the same time, in the actual application process, in order to meet different usage and processing requirements, by rotating the adjusting screw rod 4 provided at the bottom of the spraying gun body 2, the adjusting screw rod 4 rotates and realizes horizontal displacement through threaded rotation. At the same time, the push block 6 connected to the adjusting screw rod 4 moves to one side and slides on the outer wall of the spraying gun body 2, and pushes the base 51 inside it. An inclined guiding wedge 7 is provided on the base 51. When the push block 6 contacts the guiding wedge 7, the jetting frame 5 will be pushed inwards, and the included angle between the frames will be changed, so that the included angle of the paint spray is changed to change the spraying area.

[0027] On the contrary, by rotating the adjusting screw rod 4 in the reverse direction, the push block 6 moves to the other side and gradually reduces the contact area with the guiding wedge 7, so that the jetting frame 5 expands outwards by the return force of the spring 10, thereby changing the angle between the frames and increasing the spraying angle.

[0028] Among them, in the actual use process, an air intake nozzle 8 is installed on the jetting frame 5. The air intake nozzle 8 is connected to an external gas input source and outputs gas through the jetting frame 5 to realize the atomizing spray operation of the paint.

[0029] In the present utility model, by rotating the adjusting screw rod 4 at the bottom of the spraying gun body 2, the screw rod rotates to adjust the horizontal position of the pushing block 6. When the pushing block 6 translates, it pushes the air jet frame 5 inside the gun body, so that the air jet frame 5 realizes a certain angle of deflection through the settings of components such as the rotating shaft 9 and the spring 10, thereby changing the included angle between the air jet frames 5 and realizing the function of adjusting the spraying range, effectively improving the operation efficiency and increasing the spraying quality of the product.
