[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0013] Example 1 This utility model provides a spraying device for automobile wheel hub processing, such as... Figures 1 to 5 As shown, the device includes: a spraying equipment body 1, a trigger 2, and a positioning assembly. A reset device is provided between the spraying equipment body 1 and the trigger 2 to reset the trigger 2 after rotation. The spraying equipment gun handle is connected to the spraying equipment body 1, and the trigger 2 rotates inside the spraying equipment body 1. The positioning assembly includes a rotating component 3, a linkage bar 4, a pawl 5, an elastic component 6, a connecting plate 7, and a connecting shaft 8. The linkage bar 4 is an arc-shaped rack, the rotating component 3 is a sector-shaped block, and the elastic component 6 is a spring. The linkage bar 4 is connected to the trigger 2 through the rotating component 3, and the trigger... 2. The rotating component 3 drives the linkage bar 4 to rotate. The pawl 5 is connected to the linkage bar 4 and rotates inside the spraying equipment body 1 through the connecting shaft 8. One end face of the pawl 5 is connected to the connecting plate 7 through the elastic component 6. The connecting plate 7 is connected to the spraying equipment body 1. The rotating component 3 is provided with a connecting block 14. The rotating component 3 is connected to the inner wall of the trigger 2 through the rotating component 3 to limit the rotation state of the rotating component 3. The linkage bar 4 is provided with a slot. The pawl 5 is engaged with the surface of the linkage bar 4 through the slot to limit the linkage bar 4.

[0014] The coordinated action between the linkage bar 4 and the pawl 5 positions the rotated trigger 2, thus avoiding the problem of operators having to press the trigger 2 for a long time when using the equipment, thereby improving the work efficiency of the equipment.

[0015] When using this equipment to paint the wheel hub, the operator first presses trigger 2, causing it to rotate towards the main body 1 of the painting equipment. As trigger 2 rotates, it drives the rotating component 3 to rotate synchronously via connecting block 14, which in turn drives the linkage 4 to rotate. The pawl 5, with the cooperation of elastic component 6 and connecting plate 7, remains in contact with the linkage 4 during rotation. The operator stops rotating trigger 2 when it reaches the desired position. At this point, a reset device inside the main body 1 pushes trigger 2 to reset, and the rotating component 3 drives the linkage 4 to rotate in the opposite direction. When the linkage bar 4 rotates in the opposite direction, the ratchet 5 is engaged inside the linkage bar 4 through the cooperation between the elastic element 6, the connecting plate 7, and the pawl 5. At this time, the ratchet 5 restricts the linkage bar 4, preventing it from rotating in the opposite direction. Subsequently, the linkage bar 4 restricts the trigger 2, preventing it from resetting, thus completing the step of engaging the trigger 2. Through the cooperation between the linkage bar 4 and the ratchet 5, the rotated trigger 2 is positioned, avoiding the problem of the operator having to press the trigger 2 for a long time when using the equipment, thereby improving the working efficiency of the equipment.

[0016] Specifically, a trigger 2 is rotatably connected inside the spraying equipment body 1. A connecting block 14 is fixedly connected to the surface of the trigger 2, and a rotating component 3 is fixedly connected to the end of the connecting block 14 away from the trigger 2. The trigger 2 drives the rotating component 3 to rotate inside the spraying equipment body 1. A linkage bar 4 is fixedly connected to the surface of the rotating component 3. A pawl 5 is snapped into the linkage bar 4. A connecting shaft 8 is rotatably connected inside the pawl 5, and the connecting shaft 8 is fixedly connected inside the spraying equipment body 1. A connecting plate 7 is fixedly connected to one end face of the pawl 5 through an elastic component 6, and the connecting plate 7 is fixedly connected inside the spraying equipment body 1.

[0017] To achieve the separation of linkage bar 4 and pawl 5 in the above example, the following solution is proposed: Figures 2 to 5 As shown, it also includes a separation assembly, which includes a handle 9, a rotating rod 10, a magnetic component 11, a magnetic component 12, and a barrier plate 13. Both magnetic components 11 and 12 are magnets. The handle 9 rotates on the spraying equipment body 1 via the rotating rod 10. Magnetic component 11 is connected to the rotating rod 10, and magnetic component 12 is magnetically attracted to magnetic component 11. The barrier plate 13 is connected to the pawl 5 to rotate the pawl 5. The rotating rod 10 has a hexagonal protrusion, and magnetic component 11 has a hexagonal groove. The rotating rod 10 and magnetic component 11 are engaged together by the cooperation of the hexagonal protrusion and the hexagonal groove. Magnetic component 12 and the barrier plate 13 are located on both sides of magnetic component 11 to prevent magnetic component 11 from rotating accidentally.

[0018] The cooperation between handle 9, magnetic component 11 and magnetic component 2 12 allows the linkage bar 4 to be separated from the pawl 5, thereby improving the flexibility of the device during use and thus increasing the work efficiency of the operator.

[0019] In use, when the operator needs to reset the trigger 2, they turn the handle 9. The rotation of the handle 9 causes the magnetic component 11 to rotate via the rotating rod 10. This rotation separates the magnetic component 11 from the magnetic component 12, causing the barrier plate 13 to rotate. The rotation of the barrier plate 13 causes the pawl 5 to rotate inside the connecting shaft 8. During this rotation, the pawl 5 compresses and deforms the elastic component 6, separating it from the linkage bar 4. At this point, because the pawl 5 has removed its restraint on the linkage bar 4, the linkage bar 4 can no longer restrain the trigger 2. Subsequently, the reset device between the spraying equipment body 1 and the trigger 2 pushes the trigger 2 to reset, thus completing the reset of the trigger. 2. The reset step involves the operator releasing handle 9, which releases the elastic element 6, causing it to spring back. During this springback, the elastic element 6 pushes the pawl 5 to rotate in the opposite direction and adhere to the surface of the linkage bar 4. When the pawl 5 reverses, it drives the baffle plate 13 to reverse synchronously. The baffle plate 13, through the magnetic element 11, drives the handle 9 to reverse, thus completing the reset step of handle 9. Through the cooperation between handle 9, magnetic element 11, and magnetic element 2, the linkage bar 4 is separated from the pawl 5, thereby improving the flexibility of the equipment during use and increasing the work efficiency of the operator.

[0020] Specifically, a rotating rod 10 is rotatably connected inside the spraying equipment body 1. A handle 9 is fixedly connected to one end of the rotating rod 10 away from the spraying equipment body 1. A magnetic component 11 is snapped onto the surface of the rotating rod 10, and the rotating rod 10 drives the magnetic component 11 to rotate inside the spraying equipment body 1. A magnetic component 2 12 is magnetically attracted to the surface of the magnetic component 11. A barrier plate 13 is fixedly connected to the surface of the pawl 5, and the barrier plate 13 and the magnetic component 2 12 are located on both sides of the magnetic component 11.

[0021] Working Principle: When using this device to spray paint a car hub, the operator first presses trigger 2, causing it to rotate towards the spraying equipment body 1. As trigger 2 rotates, it drives the rotating component 3 to rotate synchronously via connecting block 14, which in turn drives the linkage 4. The pawl 5, with the cooperation of elastic component 6 and connecting plate 7, remains in contact with the linkage 4 during rotation. This continues until the operator rotates trigger 2 to the desired position and stops. At this point, a reset device inside the spraying equipment body 1 pushes trigger 2 to reset, and the rotating component 3 drives the linkage 4... When the linkage bar 4 rotates in the reverse direction, the ratchet 5 is engaged inside the linkage bar 4 through the cooperation between the elastic element 6, the connecting plate 7, and the pawl 5. At this time, the ratchet 5 restricts the linkage bar 4, preventing it from rotating in the reverse direction. Subsequently, the linkage bar 4 restricts the trigger 2, preventing it from resetting, thus completing the step of engaging the trigger 2. Through the cooperation between the linkage bar 4 and the ratchet 5, the rotated trigger 2 is positioned, avoiding the problem that the operator needs to press the trigger 2 for a long time when using the equipment, thereby improving the working efficiency of the equipment. When the operator needs to reset trigger 2, they turn handle 9. Turning handle 9 causes the rotating rod 10 to rotate magnetic component 11. This rotation separates magnetic component 11 from magnetic component 12, causing the barrier plate 13 to rotate. The barrier plate 13's rotation causes the pawl 5 to rotate inside the connecting shaft 8. During this rotation, the pawl 5 compresses and deforms the elastic component 6, separating it from the linkage bar 4. Because the pawl 5 has removed its restraint on the linkage bar 4, the linkage bar 4 can no longer restrain trigger 2. Subsequently, the reset device between the spraying equipment body 1 and trigger 2 pushes trigger 2 to reset, thus completing the reset of trigger 2. The steps are as follows: the operator releases handle 9, which releases the elastic element 6, causing it to spring back. During this springback, the elastic element 6 pushes the pawl 5 to rotate in the opposite direction and adhere to the surface of the linkage bar 4. When the pawl 5 reverses, it drives the baffle plate 13 to reverse synchronously. The baffle plate 13 drives the handle 9 to reverse through the magnetic element 11, thus completing the step of resetting handle 9. Through the cooperation between handle 9, magnetic element 11, and magnetic element 2, the linkage bar 4 is separated from the pawl 5, thereby improving the flexibility of the equipment during use and thus improving the work efficiency of the operator.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
