Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electrostatic spraying machines, specifically relating to a handheld structure for an electrostatic spraying machine. Background Technology
[0002] In practical use, electrostatic sprayers typically require connecting cables and paint hoses for power supply and paint delivery. However, due to frequent changes in the sprayer's position during operation, the connections between the cables and hoses are prone to bending. This not only affects the lifespan of the cables and hoses but can also lead to loose connections, affecting the normal operation of the sprayer and even posing safety hazards. Furthermore, during spraying, the sprayed liquid can easily splash onto the user's hands, posing a health risk. While some existing sprayer handheld mechanisms may offer some protection, these mechanisms are often poorly designed, lack flexibility to meet specific needs, and are inconvenient to replace, impacting efficiency and convenience. Utility Model Content
[0003] This utility model provides a handheld structure for an electrostatic spraying machine, which solves the problems of loose pipe connections and lack of protective structure in existing handheld spraying machine guns.
[0004] This utility model provides the following technical solution: It includes a spray gun body, a mounting plate installed at the bottom of the spray gun body, a fixing ring installed on the outer wall of the mounting plate, a connecting plate installed on the outer wall of the mounting plate, a sliding rod installed on the outer wall of the connecting plate, a support plate below the sliding rod, a mounting block installed on one side of the support plate, two limiting grooves rotatably connected to the inner wall of the mounting block, a top plate installed at the bottom end of the spray gun body, a bottom plate below the top plate, the top plate and the bottom plate connected by a connecting frame, a baffle slidably connected between the top plate and the bottom plate, and a first spring installed on the inner wall of the connecting frame, one end of the first spring corresponding to the baffle.
[0005] Wherein, a limiting arc plate is fixedly connected at the connection between the mounting block and the limiting groove, and a limiting block matching the limiting arc plate is provided on the outer wall of the limiting groove.
[0006] One end of the base plate is slidably connected to the outer wall of the fixing ring, and the baffle is engaged with the inner wall of the base plate.
[0007] The top plate and the bottom plate are provided with slots, and the two ends of the baffle are equipped with locking blocks that match the slots.
[0008] The connecting frame has connecting blocks installed at both ends, and uprights are installed on the connecting blocks. A second spring is sleeved on the outer wall of the upright, and the top of the second spring is located below the base plate.
[0009] The connecting frame is slidably connected to a push rod, and the first spring is sleeved on the outer wall of the push rod, with one end of the first spring connected to one end of the push rod.
[0010] The beneficial effects of this utility model are as follows: With the cooperation of the sliding rod, support plate, mounting block, and limiting groove, the cable and pipe can be securely bound and supported, ensuring that the connection point between the cable and the spray gun body remains perpendicular when the cable is dragged. This prevents the cable and pipe from bending at the connection point due to excessive movement of the spray gun body, thus ensuring the stability of the connection and extending the service life of the cable and pipe. The top plate, connecting frame, bottom plate, and baffle together constitute a hand protection structure, effectively preventing spray liquid from splashing onto the user's hands. The baffle can be replaced due to the adjustable position of the bottom plate.

[0017] Please see Figures 1-4The present invention provides the following technical solution: a spray gun body 1 is included, an mounting plate 11 is installed at the bottom of the spray gun body 1, a fixing ring 12 is installed on the outer wall of the mounting plate 11, a connecting plate 2 is installed on the outer wall of the mounting plate 11, a sliding rod 21 is installed on the outer wall of the connecting plate 2, a support plate 22 is provided below the sliding rod 21, a mounting block 23 is installed on one side of the support plate 22, two limiting grooves 24 are rotatably connected to the inner wall of the mounting block 23, a top plate 3 is installed at the bottom of the spray gun body 1, a bottom plate 32 is provided below the top plate 3, the top plate 3 and the bottom plate 32 are connected by a connecting frame 31, a baffle 321 is slidably connected between the top plate 3 and the bottom plate 32, a first spring 322 is installed on the inner wall of the connecting frame 31, and one end of the first spring 322 corresponds to the baffle 321.
[0018] In this implementation scheme: the spray gun body 1 serves as the carrier of the supporting device. The mounting plate 11 installed at the bottom of the spray gun body 1 supports the fixing ring 12, allowing the fixing ring 12 to be mounted on the outer wall of the mounting plate 11. At this time, the connecting plate 2 installed on the outer wall of the fixing ring 12 can mount the sliding rod 21, which slides on the connecting plate 2. The support plate 22 installed at the bottom of the sliding rod 21 can mount the mounting block 23. The mounting block 23 corresponds to the cable and paint tube connected to the bottom of the spray gun body 1, allowing the mounting block 23 to... The notch on the outer wall of the limiting groove 24 installed on the inner wall allows cables and pipes to be inserted into the limiting groove 24. Rotation of the limiting groove 24 adjusts the notch to align with the inner wall of the mounting block 23, thus limiting the cables and pipes and providing support from the connecting plate 2. This causes the sliding rod 21 to slide, pushing the mounting block 23 to its outer end. The mounting block 23 then binds and supports the cables and pipes, ensuring that the connection point between the cables and pipes and the spray gun body 1 is perpendicular during dragging, preventing manipulation of the spray gun body 1. During use, the spray gun body 1 undergoes frequent positional changes, causing bending of cables and pipes at connections, affecting their stable connection. Simultaneously, during use, the top plate 3 mounted on the spray gun body 1 can connect and support the bottom plate 32 via the connecting bracket 31. The bottom plate 32, positioned below the connecting bracket 31, can be adjusted in height. At this time, the slots 33 on the top plate 3 and bottom plate 32 can connect and engage the locking blocks 331 mounted at the upper and lower ends of the baffle 321, allowing the slots 33 to limit the locking blocks 331, thus enabling the baffle 321 to... Located at the front of the handheld part of the spray gun body 1, it protects the user's hands from splashes of sprayed liquid, preventing harm to the user's hands. At the same time, the baffle 321 can be removed and replaced by pulling down the base plate 32. After the frontmost baffle 321 is removed, the first spring 322, located in the connecting frame 31, can push the baffle 321. The first spring 322 supports the adjacent baffle 321 to the outside, which facilitates the protection of the user and the replacement of the baffle.
[0019] A limiting arc plate 231 is fixedly connected at the connection between the mounting block 23 and the limiting groove 24. A limiting block 241 matching the limiting arc plate 231 is provided on the outer wall of the limiting groove 24. The limiting arc plate 231 is used to limit the limiting block 241 on the outer wall of the limiting groove 24, so that the limiting groove 24 can slide stably on the inner wall of the mounting block 23, and the position of the limiting groove 24 can be adjusted so that the position of the limiting groove 24 can be adjusted to the position that limits the cable conduit, and can be adjusted to the position that makes it easy to push the cable conduit in.
[0020] One end of the base plate 32 is slidably connected to the outer wall of the fixing ring 12, and the baffle 321 is engaged with the inner wall of the base plate 32. The slidable connection between the base plate 32 and the outer wall of the fixing ring 12 allows the base plate 32 to be height-adjustable and supported by the fixing ring 12, so that the top plate 3, the connecting frame 31 and the base plate 32 remain vertically aligned. The baffle 321 is engaged with the inner wall of the base plate 32, so that the baffle 321 can be engaged and supported in the inner wall of the base plate 32 to protect the user's hands.
[0021] The top plate 3 and the bottom plate 32 are provided with slots 33, and the baffle 321 is equipped with locking blocks 331 that match the slots 33 at both ends. The slots 33 on the top plate 3 and the bottom plate 32 can connect and limit the locking blocks 331, so that the baffle 321 can be supported and limited between the top plate 3 and the bottom plate 32. At the same time, the baffle 321 can slide on the inner wall of the top plate 3 and the bottom plate 32, so that the baffle 321 can be pushed by the first spring 322.
[0022] Connecting blocks 311 are installed at both ends of the connecting frame 31. A vertical rod 34 is installed on the connecting block 311. A second spring 35 is sleeved on the outer wall of the vertical rod 34. The top of the second spring 35 is below the base plate 32. The connecting blocks 311 installed at both ends of the connecting frame 31 can connect the vertical rod 34, so that the second spring 35 sleeved on the outer wall of the vertical rod 34 can support the bottom of the base plate 32. The base plate 32 can be supported to the position where the locking block 331 installed at the bottom of the baffle 321 is limited. At the same time, pressure can be applied to the base plate 32, causing the base plate 32 to move down and causing the baffle 321 to be misaligned with the locking slot 33, so that the baffle 321 can be removed and replaced.
[0023] A push rod 323 is slidably connected to the connecting frame 31. A first spring 322 is sleeved on the outer wall of the push rod 323, and one end of the first spring 322 is connected to one end of the push rod 323. The push rod 323 slides on the connecting frame 31. The push rod 323 sleeved on the outer wall of the push rod 323 is supported by the first spring 322, so that the push rod 323 can be pushed, so that the baffle 321 can be pushed, so that the baffle 321 can be supported and slid on the inner wall of the base plate 32, so that each baffle 321 can be pushed to the outer end of the inner wall of the base plate 32. After the baffle 321 is removed, the adjacent baffle 321 can be pushed back to the original position of the baffle 321 to protect the user's hands.
[0024] The working principle and usage process of this utility model are as follows: The sliding rod 21 moves the support plate 22 and the mounting block 23, adjusting the limiting groove 24 to a suitable position so that cables and pipes can be inserted into the limiting groove 24 through the notch on its outer wall. Then, the limiting groove 24 is rotated so that the notch aligns with the inner wall of the mounting block 23, limiting and supporting the cables and pipes. The locking blocks 331 at both ends of the baffle 321 are then inserted into the locking slots 33 on the top plate 3 and the bottom plate 32, supporting the baffle 321 between the top plate 3 and the bottom plate 32. To protect the user's hands, the sprayed liquid will be blocked by the baffle 321 during use, preventing splashing onto the user's hands. When the baffle 321 needs to be replaced, pressure is applied to the second spring 35 to move the base plate 32 down, causing the baffle 321 to be misaligned with the slot 33, and the baffle 321 can be removed. After removing one baffle 321, the first spring 322 will push the adjacent baffle 321 to the outside, so that it occupies the original position of the baffle 321 and continues to provide protection for the user. Afterwards, the new baffle 321 can be installed in the appropriate position.
