Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a surface painting device for manufacturing household appliances, which solves the problems in the related art of inconvenient precise control of the spraying range and inconvenient cleaning after use.

[0006] The technical solution of the utility model is as follows:

[0007] A surface painting equipment for manufacturing household appliances comprises a spray gun, wherein a connecting pipe is fixedly connected to one side of the outside of the spray gun, one end of the connecting pipe is fixedly connected to a paint bucket, an air pump is fixedly connected to the bottom of the paint bucket, a power switch is rotatably connected to the front of the spray gun, a nozzle is provided on one side of the outside of the spray gun, a hollow plate is fixedly connected to the outside of the nozzle, a baffle is provided on one side of the outside of the hollow plate, the baffle and the hollow plate are movably connected via a damping rotating shaft, a fixing rod is fixedly connected to the inside of the hollow plate, a round rod is slidably connected to the inside of the fixing rod, elastic springs are fixedly connected to the two sides of the outside of the round rod, the outer ends of the two elastic springs are fixedly connected to a rotating plate, a fixing block is provided between the two rotating plates, the fixing block and the two rotating plates are movably connected via a rotating shaft, and a fixing box is fixedly connected to one side of the spray gun.

[0008] Preferably, the hollow plate is in contact with the spray gun, and the two elastic springs are symmetrically distributed.

[0009] Preferably, one end of the round rod is located inside the fixing box, and the nozzle extends into the interior of the spray gun and is adapted to the interior of the spray gun.

[0010] Preferably, the round rod is fixedly connected to the fixed block, and an acute angle is formed between the round rod and the rotating plate.

[0012] Preferably, a sliding rod is slidably connected inside the round rod, and a spring is provided outside the sliding rod.

[0013] Preferably, one end of the sliding rod is fixedly connected to a round cap, and both sides of the outside of the round cap are fixedly connected to fixing plates.

[0014] Preferably, both ends of the spring are fixedly connected to the round cap and the fixed block respectively, and the fixed plate is in contact with the rotating plate.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, the round rod is pushed forward, and the round rod drives the elastic spring and the fixed block to be pushed at the same time, and the fixed block drives the rotating plate to be pushed at the same time. When the rotating plate is pushed to the entrance of the fixed box and contacts with it, the rotating plate is forced to drive the elastic spring to be compressed, and the rotating plate enters the fixed box at this time. After the rotating plate enters the fixed box, the force disappears and the elastic spring is reset. The elastic spring resets and drives the rotating plate to be reset at the same time. At this time, the rotating plate and the fixed box are fixed, and the hollow plate and the spray gun are also fixedly connected due to the above work, which solves the problem of inconvenient precise control of the spraying range and cleaning after use;

[0017] 2. In the utility model, by rotating the baffle downward, the paint sprayed from the nozzle is blocked by the baffle, and the spraying range is reduced. On the contrary, when the spraying range needs to be expanded, the baffle is rotated upward, and the spraying range becomes larger. This makes it easier for the staff to accurately control the spraying range during the spraying work, improves the spraying efficiency, and solves the problem of inconvenient precise control of the spraying range and cleaning after use.

[0018] 3. In the utility model, the staff first pushes the round rod forward, and the fixed block is pushed while the round rod moves, and the rotating plate is pushed while the fixed block is pushed. At this time, the spring is compressed to the bottom of the round cap, and the elastic spring is compressed while the rotating plate is stressed. At this time, the rotating plate enters the bottom of the fixed plate and contacts it. At the same time, the angle between the rotating plate and the round rod is reduced. When the angle is smaller than the diameter at the entrance of the fixed box, the staff can pull out the rotating plate to release the fixed relationship. At this time, the staff only needs to remove the hollow plate for cleaning, which can facilitate the staff to efficiently clean the residual paint, solving the problem of inconvenient precise control of the spraying range and cleaning after use.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 to Figure 3 As shown, the present embodiment proposes a surface painting device for manufacturing household appliances, including a spray gun 1, a connecting pipe 2 is fixedly connected to one side of the outside of the spray gun 1, a paint bucket 3 is fixedly connected to one end of the connecting pipe 2, an air pump 4 is fixedly connected to the bottom of the paint bucket 3, a power switch 5 is rotatably connected to the front of the spray gun 1, a nozzle 6 is provided on one side of the outside of the spray gun 1, a hollow plate 8 is fixedly connected to the outside of the nozzle 6, a baffle 7 is provided on one side of the outside of the hollow plate 8, the baffle 7 and the hollow plate 8 are movably connected through a damping shaft, a fixed rod 10 is fixedly connected to the inside of the hollow plate 8, a round rod 9 is slidably connected to the inside of the fixed rod 10, elastic springs 12 are fixedly connected to both sides of the outside of the round rod 9, the outer ends of the two elastic springs 12 are fixedly connected to a rotating plate 11, a fixed block 13 is provided between the two rotating plates 11, the fixed block 13 and the two rotating plates 11 are movably connected through a rotating shaft, and a fixed box 18 is fixedly connected to one side of the spray gun 1.

[0028] In this embodiment, the hollow plate 8 is in contact with the spray gun 1 , and the two elastic springs 12 are symmetrically distributed, which can facilitate the installation and removal of the hollow plate 8 .

[0029] In this embodiment, one end of the round rod 9 is located inside the fixing box 18 , and the nozzle 6 extends into the interior of the spray gun 1 and fits in with the interior of the spray gun 1 , which can facilitate installation and removal of the nozzle 6 .

[0030] In this embodiment, the round rod 9 is fixedly connected to the fixed block 13, and there is an acute angle between the round rod 9 and the rotating plate 11, so that the fixed block 13 can move synchronously with the round rod 9 when it is forced to move.

[0031] In this embodiment, the two rotating plates 11 are both in contact with one side of the interior of the fixing box 18 , and the two rotating plates 11 are symmetrically distributed, which can facilitate the fixation between the rotating plates 11 and the fixing box 18 .

[0032] When in use, the staff first needs to open the paint bucket 3 to fill the paint, then turn the power switch 5 to power on, at this time the air pump 4 starts to work, the paint will be transported to the inside of the spray gun 1 through the connecting pipe 2, and then the paint will be sprayed evenly onto the surface of the object through the nozzle 6. When it is necessary to adjust the range of the spray, the staff can install the hollow plate 8 on the top of the nozzle 6, and then push the round rod 9 forward. The round rod 9 pushes the elastic spring 12 and the fixed block 13 at the same time, and the fixed block 13 pushes the rotating plate 11 at the same time. When the rotating plate 11 is pushed to the entrance of the fixed box 18 and contacts it, the rotating plate 11 is forced to drive the elastic spring 12 to compress, and at this time the rotating plate 11 enters the fixed box 18 When the rotating plate 11 enters the fixed box 18, the force disappears and the elastic spring 12 is reset. When the elastic spring 12 is reset, the rotating plate 11 is driven to reset. At this time, the rotating plate 11 is fixed to the fixed box 18, and the hollow plate 8 and the spray gun 1 are also fixedly connected due to the above work. At this time, the staff can adjust the rotation angle of the baffle 7 according to the needs. When the spraying range needs to be reduced, the baffle 7 is rotated downward. At this time, the paint sprayed by the nozzle 6 is blocked by the baffle 7, and the spraying range is reduced. On the contrary, when the spraying range needs to be expanded, the baffle 7 is rotated upward, and the spraying range becomes larger. This can facilitate the staff to accurately control the spraying range when performing spraying work, thereby improving the spraying efficiency.

[0033] Example 2

[0034] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a sliding rod 15 is slidably connected inside the round rod 9, and a spring 14 is provided outside the sliding rod 15 to facilitate the spring 14 to perform telescopic movement.

[0035] In this embodiment, a round cap 17 is fixedly connected to one end of the sliding rod 15 , and fixing plates 16 are fixedly connected to both sides of the outside of the round cap 17 , which can facilitate the sliding movement of the sliding rod 15 inside the round rod 9 .

[0036] In this embodiment, the two ends of the spring 14 are fixedly connected to the round cap 17 and the fixed block 13 respectively, and the fixed plate 16 is in contact with the rotating plate 11, so that the spring 14 can drive the fixed plate 16 to contact the rotating plate 11 when the rotating plate 11 is in telescopic movement, and the rotating plate 11 can be extended and retracted.

[0037] During use, when spraying is finished and the paint remaining on the surface of the nozzle 6 needs to be cleaned, it can be disassembled and cleaned. At this time, the staff first pushes the round rod 9 to move forward and keeps applying force. While the round rod 9 moves, the fixed block 13 is pushed, and while the fixed block 13 is pushed, the rotating plate 11 is pushed. At this time, the spring 14 is compressed to one side of the bottom of the round cap 17, and the round rod 9 will slide outside the sliding rod 15. While the rotating plate 11 is under force, the elastic spring 12 is compressed. At this time, the rotating plate 11 will enter the bottom of the fixed plate 16 and contact it. At the same time, the angle between the rotating plate 11 and the round rod 9 is reduced. When the angle is smaller than the caliber at the entrance of the fixed box 18, the staff can pull out the rotating plate 11 to release the fixing relationship. At this time, the staff only needs to remove the nozzle 6 and the hollow plate 8 for cleaning, which can facilitate the staff to efficiently clean the residual paint.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
