Description

Technical Field

[0001] This utility model relates to the field of hardware spraying equipment technology, and in particular to a surface spraying device for hardware products. Background Technology

[0002] Hardware products are made from metal materials (such as iron, copper, aluminum, stainless steel, etc.) through processes such as casting, forging, cutting, stamping, and welding. In their production process, the coating process is crucial to achieving the required appearance and protective properties. To obtain a uniform paint film and reduce paint waste, a spray gun is used to evenly adhere paint to the surface of the hardware product, improving product quality and aesthetics. In existing technologies, some spray guns are equipped with paint canisters to store the paint, coatings, or other media to be sprayed. During operation, the paint is delivered to the nozzle of the spray gun via siphon or pressure, thus completing the painting operation. However, when the paint canister is full, the paint itself has a certain weight, and the overall design of the spray gun makes the lower part of the paint canister heavier. This disrupts the gun's originally relatively balanced center of gravity distribution, causing the center of gravity to shift downwards and towards one side of the paint canister. Holding the spray gun requires more wrist strength to maintain balance, which can easily lead to fatigue and make it difficult to control the direction and angle of the spray gun, thus affecting the accuracy and smoothness of the spraying. Therefore, it is inconvenient to hold the spray gun. Utility Model Content

[0003] The purpose of this invention is to address the problem that when the paint canister on some existing spray guns is filled with paint, the weight of the paint in the canister will disrupt the center of gravity of the spray gun, making it inconvenient to hold. This invention proposes a surface spraying device for hardware products.

[0004] The technical solution of this utility model is as follows: A surface spraying device for hardware products includes a spray gun, and further includes: a rotating support block and a spiral support block fixedly connected to the outer walls on both sides of the spray gun, and an adjusting rod rotatably connected to each of the rotating support block and the spiral support block, and a dispersing mechanism is provided at the end of each pair of adjusting rods away from the spray gun; a locking mechanism is provided, and the adjusted dispersing mechanism is fixed by being spirally sleeved on the spiral support block.

[0005] Optionally, the dispersing mechanism includes a wrist strap that rests on the wrist, and a connector is fixedly connected to the end of the adjusting rod away from the spray gun. A support block is fixedly connected to the connector, and a mounting hole is provided on the support block. A rectangular ring is movably connected inside the mounting hole, and the rectangular ring is movably connected to the corresponding end of the wrist strap.

[0006] Optionally, the locking mechanism includes a spiral sleeve that is spirally sleeved on the spiral support block, and a rotating sleeve is fixedly connected to one end of the adjusting rod near the spray gun. One of the rotating sleeves has multiple anti-slip grooves arranged in a circumferential array, and multiple anti-slip protrusions arranged in a circumferential array are fixedly connected to one end of the spiral sleeve near the rotating sleeve.

[0007] Optionally, the spiral sleeve is provided with a plurality of anti-slip grooves arranged in a circumferential array.

[0008] Optionally, a locking block is fixedly connected to the end of the rotating support block and the spiral support block away from the spray gun.

[0009] Optionally, the bottom of the spray gun is also movably equipped with a paint tank, and the middle part is also provided with a widening band.

[0010] In summary, this application includes at least one of the following beneficial technical effects: This invention utilizes a spray gun, paint can, adjusting rod, wrist strap, and locking mechanism. When using the device, paint is first loaded into the paint can. The adjusting rod is adjusted by rotating the support block and the spiral support block. The wrist strap, via a rectangular ring, is placed on the wrist, its widened width increasing the contact area and distributing weight to the wrist, reducing pressure on the hand's center of gravity. Rotating the spiral sleeve causes the anti-slip protrusions to engage with the groove in the rotating sleeve, securing the adjusting rod. This structural combination effectively prevents center of gravity shift, balances the overall center of gravity, reduces wrist strain to alleviate fatigue, and thus stabilizes spray gun control, improving spraying accuracy and smoothness.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0019] like Figures 1 to 5As shown, this utility model proposes a surface spraying device for hardware products, including a spray gun 1. A paint tank 11 is movably mounted on the bottom of the spray gun 1. Rotating support blocks 12 and spiral support blocks 13 are fixedly connected to the outer walls on both sides of the spray gun 1. The rotating support blocks 12 are fixed to the outer wall of the spray gun 1 and rotatably connected to the adjusting rod 2, providing a fulcrum for the adjustment rod 2 to facilitate adjustment of the angle of the adjusting rod 2. The spiral support blocks 13 are fixed to the outer wall of the spray gun 1, providing a fulcrum for the adjustment rod 2 and a spiral mounting base for the spiral sleeve 15, and are used in conjunction with a locking mechanism to fix the adjusting rod 2. Adjusting rods 2 are rotatably connected to both the rotating support blocks 12 and the spiral support blocks 13. The two ends of the adjusting rods 2 are respectively connected to the rotating support blocks 12 and the spiral support blocks 13 and to the dispersing mechanism. By rotating to adjust the angle, the supporting force of the dispersing mechanism is transmitted to the spray gun 1 to assist in balancing the center of gravity.

[0020] Among them, such as Figures 1 to 4 As shown, a pair of adjusting rods 2 have a dispersing mechanism at the end furthest from the spray gun 1. This dispersing mechanism includes a wrist strap 26 that rests on the wrist. The wrist strap 26 is connected to the adjusting rod 2 via a rectangular ring 25, etc., and rests on the wrist to distribute part of the weight of the spray gun 1 and paint can 11 to the wrist, balancing the center of gravity. Each adjusting rod 2 has a connector 23 fixedly connected to its end furthest from the spray gun 1. Each connector 23 has a support block 24 fixedly connected to it. The support block 24 is fixed to the connector 23 and has mounting holes 27 to provide a mounting position for the rectangular ring 25, connecting the connector 23 and the rectangular ring 25. Each support block 24 has a mounting hole 27, and a rectangular ring 25 is movably connected inside the mounting hole 27. The rectangular ring 25 is movably connected within the mounting hole 27 of the support block 24 and simultaneously movably connected to the end of the wrist strap 26, connecting the wrist strap 26 to the support block 24. The angle can be flexibly adjusted to fit the wrist. The rectangular ring 25 is movably connected to the corresponding end of the wrist strap 26.

[0021] Secondly, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the spiral support block 13 is spirally fitted with a locking mechanism that fixes the dispersing mechanism after adjustment. The locking mechanism includes a spiral sleeve 15 spirally fitted on the spiral support block 13. The spiral sleeve 15 is spirally fitted on the spiral support block 13 and can move along the spiral support block 13 by rotation. The anti-slip protrusion 17 at its end can be engaged with the anti-slip groove 22 of the rotating sleeve 21 to fix the position of the adjusting rod 2. The spiral sleeve 15 has multiple anti-slip grooves 16 distributed in a circumferential array. The anti-slip grooves 16 are formed on the spiral sleeve 15 to increase the friction between the hand and the spiral sleeve 15, making it easier to apply force when rotating the spiral sleeve 15 and preventing slippage.

[0022] In addition, such as Figures 2 to 5As shown, a rotating sleeve 21 is fixedly connected to the end of the adjusting rod 2 near the spray gun 1. The rotating sleeve 21 is fixed to the end of the adjusting rod 2 near the spray gun 1 and is sleeved on the rotating support block 12 and the spiral support block 13, allowing the adjusting rod 2 to rotate around the support block. It also provides an anti-slip groove 22 for engaging the anti-slip protrusion 17. One of the rotating sleeves 21 has multiple anti-slip grooves 22 arranged in a circumferential array. These grooves engage with the anti-slip protrusion 17 of the spiral sleeve 15, enhancing the connection stability between the rotating sleeve 21 and the spiral sleeve 15 and fixing the angle of the adjusting rod 2. The end of the spiral sleeve 15 near the rotating sleeve 21 is fixedly connected to multiple anti-slip protrusions 17 arranged in a circumferential array. These protrusions 17 are fixed to the end of the spiral sleeve 15 near the rotating sleeve 21. When the spiral sleeve 15 is rotated, they engage with the anti-slip grooves 22 of the rotating sleeve 21, enhancing the connection and fixation effect between the spiral sleeve 15 and the rotating sleeve 21.

[0023] It is worth noting that, such as Figures 1 to 3 As shown, a locking block 14 is fixedly connected to the end of the rotating support block 12 and the spiral support block 13 away from the spray gun 1. The locking block 14 is fixed to the end of the rotating support block 12 and the spiral support block 13 away from the spray gun 1 to prevent the rotating sleeve 21 at the end of the adjusting rod 2 from falling off the support block and to ensure connection stability.

[0024] Furthermore, such as Figures 1 to 4 As shown, the wrist strap 26 also features a wider strap 28 in the middle. This wider strap 28, positioned in the middle of the wrist strap 26, increases the contact area between the wrist strap 26 and the wrist, distributing pressure, improving wearing stability and comfort, and enhancing weight distribution. The wider strap 28 can also be made of rubber to further increase comfort in contact with the wrist.

[0025] In this embodiment, when using the surface spraying device for hardware products, after loading the paint into the paint tank 11 at the bottom of the spray gun 1, the angle of the adjusting rod 2 can be adjusted first by rotating the support block 12 and the spiral support block 13 as the center. During adjustment, the rotating sleeve 21 rotates on the rotating support block 12 and the spiral support block 13. At this time, the locking block 14 can prevent the rotating sleeve 21 at the end of the adjusting rod 2 from falling off. After the pair of adjusting rods 2 are adjusted, the wrist strap 26 is placed on the wrist through the connector 23, the support block 24 and the rectangular ring 25. At the same time, the widening band 28 increases the contact area and improves stability. The rectangular ring 25 is fitted and adjusted in the mounting hole 27 of the support block 24 to ensure hand balance. After the adjustment is completed, the spiral sleeve 15 is rotated. Since the spiral sleeve 15 and the spiral support block 13 are spirally connected, the spiral sleeve 15 can be moved along the spiral support block 13 until the anti-slip protrusion 17 is engaged in the anti-slip groove 22 of the rotating sleeve 21. Applying force through the anti-slip groove 16 can save effort. During spraying, the paint is sprayed out through the spray gun 1, and the wide strap 28 placed on the wrist can prevent the weight of the spray gun 1 and the paint can 11 from being entirely on the hand.

[0026] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
