Description

Technical Field

[0001] This utility model relates to the technical field of decorative and finishing tools, and in particular to a spray painting tool. Background Technology

[0002] In the field of civil engineering decoration and renovation construction, various paints and coatings are frequently used, mostly in canned form. During application, operators hold the spray can and spray the area to be coated. However, to meet performance requirements such as adhesion and drying speed, most canned paints and coatings contain a large amount of volatile organic compounds (VOCs), such as solvents like benzene, toluene, and xylene. These substances are not only highly flammable, but their vapors, when mixed with air, can easily ignite or even explode when they come into contact with sparks from welding operations, electrical sparks from temporary electrical equipment on the construction site, or even open flames such as unextinguished cigarette butts. According to industry safety statistics, nearly 60% of fires caused by paint spraying during the decoration and renovation phase are due to the accidental ignition of these volatile gases, which not only damages construction materials but also potentially endangers the lives of personnel on site.

[0003] Meanwhile, the health hazards of these toxic gases to operators are more persistent. During the spraying process, the aerosols formed by solvent evaporation permeate the work environment. Although some workers wear simple masks, these protective devices are ineffective at blocking small-molecule toxic substances. Prolonged close contact with undried coatings causes workers to continuously inhale toxic gases, which may cause short-term symptoms such as dizziness, nausea, and respiratory irritation. Long-term accumulation can lead to damage to hematopoietic function, decreased liver and kidney function, and even induce malignant diseases such as leukemia. More concerning is that some construction teams, in order to meet deadlines, work continuously in enclosed spaces (such as underground parking garages and elevator shafts) without effective ventilation, causing a sharp increase in toxic gas concentrations and further exacerbating health risks.

[0004] While fully automated paint spraying devices have emerged in the industry to address these issues, employing robotic arms to precisely control the spraying path and utilizing negative pressure gas collection systems to reduce the diffusion of harmful gases, significantly lowering safety hazards and health risks, their widespread adoption is limited by practical constraints. The core components of fully automated devices include high-precision sensors, servo drive systems, and intelligent control systems. Not only are their manufacturing costs high, often reaching hundreds of thousands of yuan, making them unaffordable for small and medium-sized construction companies, but their complex structural design also requires specialized technicians for daily maintenance and program debugging, skills lacking in most construction teams. Furthermore, fully automated equipment is better suited for standardized spraying of large, regular walls. For scenarios requiring meticulous handling, such as the restoration of ancient buildings or the decoration of irregularly shaped components, its flexibility is inferior to manual operation, hindering its widespread adoption across diverse construction needs. Therefore, a painting tool is urgently needed to solve these technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a spray painting tool to solve the problems existing in the prior art, enabling operators to spray paint away from the paint can, reducing the probability of contact, and at a lower cost.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a spray painting tool, including a fixed rod, a locking component, a pressure plate, a connecting component, and an operating wrench. The locking component is fixedly disposed at the first end of the fixed rod and is used to fix the paint can to the fixed rod. One end of the pressure plate is rotatably connected to the top of the fixed rod, and the other end of the pressure plate is located above the spray button of the paint can. The first end of the operating wrench is rotatably connected to the second end of the fixed rod and is used for turning. The two ends of the connecting component are respectively fixedly connected to the bottom of the pressure plate and the operating wrench. Turning the operating wrench can pull the connecting component and cause the pressure plate to press the spray button of the paint can.

[0008] In some embodiments, the locking member includes a fixed plate, a connecting rod, a movable plate, and a locking member. The fixed plate is fixedly connected to a first end of the fixed rod, the first end of the connecting rod is fixedly connected to the movable plate, the second end of the connecting rod slides through the fixed plate, and the locking member is connected to the connecting rod and can restrict the movement of the connecting rod relative to the fixed plate. The movable plate and the fixed plate are used to clamp the paint can.

[0009] In some embodiments, the connecting rod is a lead screw, the locking element is a nut, the nut is disposed on the side of the fixed plate away from the moving plate, and is threadedly connected to the lead screw.

[0010] In some embodiments, two lead screws are provided and are respectively connected to the two ends of the movable plate, with the paint can located between the two lead screws.

[0011] In some embodiments, the nut is a wing nut.

[0012] In some embodiments, both the fixed plate and the movable plate have arc-shaped grooves on their opposite sides, and the paint can is disposed between the arc-shaped grooves.

[0013] In some embodiments, both the fixed plate and the movable plate have anti-slip textures on their arc-shaped grooves.

[0014] In some embodiments, a support rod is also included, which is vertically and fixedly disposed above the fixing rod, and one end of the pressure plate is rotatably connected to the end of the support rod away from the fixing rod.

[0015] In some embodiments, a support rod and a rotating wheel are also included. The support rod is vertically and fixedly disposed above the fixed rod and located between the locking member and the support rod.

The connecting member can pass through the fixed rod and the through space to connect the pressure plate to the operating wrench, and the connecting member can fit against the rotating wheel.

[0016] In some embodiments, the connector is a rigid component.

[0017] The present invention achieves the following technical advantages over the prior art:

[0018] This utility model provides a spray painting tool that achieves indirect contact between the operator and the paint can's spray button through the cooperation of a fixed rod, a connecting piece, and an operating wrench. Traditional handheld spray painting requires direct hand pressure on the spray button, easily resulting in paint contamination and potential skin contact due to paint leakage. In this tool, the operator only needs to operate the wrench located at the second end of the fixed rod, which, through the connecting piece, drives the pressure plate to press the spray button, effectively reducing direct hand contact with paint and lowering the risk of toxic substances penetrating through the skin. Simultaneously, the length of the fixed rod can be designed according to needs, increasing the distance between the operator and the spraying area, reducing the probability of inhaling toxic fumes and providing greater health protection. Composed of basic components such as the fixed rod, locking piece, pressure plate, connecting piece, and operating wrench, it is easy to manufacture and its cost is far lower than fully automatic spraying devices, making it more suitable for small and medium-sized construction teams or individuals. Furthermore, the compact connection of each component, small size, and light weight make it easy to carry and store, without adding extra burden to construction and transportation, making it particularly suitable for scenarios requiring frequent relocation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this invention is to provide a spray painting tool to solve the problems existing in the prior art, enabling operators to spray paint away from the paint can, reducing the probability of contact, and at a lower cost.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-3As shown, this utility model provides a spray painting tool, including a fixing rod 1, a locking member 5, a pressure plate 4, a connecting member 2, and an operating wrench 3. The locking member 5 is fixedly disposed at the first end of the fixing rod 1 and is used to fix the paint can 101 to the fixing rod 1. One end of the pressure plate 4 is rotatably connected to the top of the fixing rod 1, and the other end of the pressure plate 4 is located above the spray button of the paint can 101. The first end of the operating wrench 3 is rotatably connected to the second end of the fixing rod 1, and the second end of the operating wrench 3 is used for turning. The two ends of the connecting member 2 are respectively fixedly connected to the bottom of the pressure plate 4 and the operating wrench 3. Turning the operating wrench 3 can pull the connecting member 2 and cause the pressure plate 4 to press the spray button of the paint can 101. Through the cooperation of the fixing rod 1, the connecting member 2, and the operating wrench 3, indirect contact between the operator and the spray button of the paint can 101 is achieved. Traditional handheld spray painting requires direct hand pressure on the spray button, which easily leads to paint contamination and potential skin contact due to paint leakage. In this tool, the operator simply operates the lever 3 at the second end of the fixed rod 1, which, via the connecting piece 2, drives the pressure plate 4 to press the spray button. This effectively reduces direct hand contact with paint, lowering the risk of toxic substances penetrating the skin. Furthermore, the length of the fixed rod 1 can be customized to increase the distance between the operator and the spraying area, reducing the probability of inhaling toxic fumes and providing greater health protection. Composed of basic components such as the fixed rod 1, locking piece 5, pressure plate 4, connecting piece 2, and operating lever 3, this tool is easy to manufacture and significantly cheaper than fully automatic spraying devices, making it more suitable for small to medium-sized construction teams or individuals. Additionally, the compact design of the components, small size, and light weight make it easy to carry and store, without adding extra burden to construction and transportation, making it particularly suitable for scenarios requiring frequent relocation.

[0028] It should be noted that the length of the fixing rod 1 is 24-32cm, preferably 28cm, which is roughly the length of a human forearm. This length is proportionate to the human forearm and conforms to daily limb movement habits. When the operator operates the wrench 3, their arm does not need to be excessively extended or bent, allowing for natural force application. This ensures stable and precise pressure from the pressure plate 4 on the spray button of the paint can 101, avoiding operational delays or unstable force due to an excessively long rod, while also preventing the indirect operation from being rendered unsafe due to an excessively short rod. For common scenarios such as painting small and medium-sized objects and local repairs, this length maintains a reasonable safe distance between the operator and the painting area (avoiding excessive paint mist inhalation at close range) while also preventing difficulty in observing the painting effect due to excessive distance. This facilitates real-time adjustment of the painting angle and range, improving operational accuracy.

[0029] In some embodiments, the locking member 5 includes a fixed plate 53, a connecting rod, a movable plate 51, and a locking member. The fixed plate 53 is fixedly connected to the first end of the fixed rod 1, the first end of the connecting rod is fixedly connected to the movable plate 51, and the second end of the connecting rod slides through the fixed plate 53. The locking member is connected to the connecting rod and can restrict the movement of the connecting rod relative to the fixed plate 53. The movable plate 51 and the fixed plate 53 are used to clamp the paint can 101. By sliding the connecting rod on the fixed plate 53, the distance between the movable plate 51 and the fixed plate 53 can be flexibly adjusted to adapt to the clamping requirements of paint cans 101 of different diameters and sizes. Whether it is a small portable paint can 101 or a slightly larger capacity paint can 101, a stable fixation can be achieved by adjusting the position of the movable plate 51, without the need to equip a separate tool for a specific size paint can 101, thus improving the applicability of the tool. The movable plate 51 and the fixed plate 53 clamp the paint can 101 from both sides. Together with the locking mechanism, they lock the position of the connecting rod, securing the paint can 101 to the fixed rod 1. This prevents spraying position deviations or unstable pressing caused by the paint can 101 shaking or shifting during the painting process. Especially in scenarios such as inclined spraying or high-altitude operations, this stable fixation ensures operational accuracy and reduces paint waste and the risk of rework.

[0030] In some embodiments, the connecting rod is a lead screw 52, ​​and the locking element is a nut. The nut is located on the side of the fixed plate 53 away from the moving plate 51 and is threadedly connected to the lead screw 52. The lead screw 52 and the nut are tightly engaged by the thread, and the self-locking property of the thread can stably lock the clamping force between the moving plate 51 and the fixed plate 53. When the nut is tightened, pressure can be precisely applied through the thread transmission, so that the paint can 101 is firmly clamped. Even in working environments with vibration or tilt, it is not easy to loosen or shift, which greatly improves the stability of the painting process.

[0031] It should be noted that the lead screw can also be configured in other ways. For example, the lead screw can pass through the moving plate 51 and the fixed plate 53 and be threaded together. The side of the moving plate 51 facing away from the fixed plate 53 is provided with an abutment head, which is fixedly connected to the lead screw and can abut against the moving plate 51. In addition, the locking member 5 can also be configured in other forms, as long as it can achieve the clamping and locking of the paint can 101. For example, it can be directly configured as a plate groove structure, with an extension plate at the end of the fixed rod 1 and a fixing groove on the extension plate, in which the paint can 101 can be placed.

[0032] In some embodiments, two lead screws 52 are provided, each connected to one end of the moving plate 51, with the paint can 101 positioned between the two lead screws 52. The two lead screws 52 exert force from both ends of the moving plate 51, forming a symmetrical clamping structure with the fixed plate 53. This ensures that the paint can 101 is subjected to uniform force on both sides, preventing tilting or displacement of the paint can 101 due to single-point or unilateral clamping. Especially when angle adjustments are required during painting, the symmetrical clamping force ensures that the paint can 101 maintains a stable posture, reducing spraying deviations caused by uneven force.

[0033] In some embodiments, the nut is a wing nut 54. The wing nut 54 has wide wing-shaped tabs at both ends, allowing the operator to directly grasp the tabs and rotate it without the need for wrenches, pliers, or other auxiliary tools. This is especially beneficial in complex construction environments where tools are inconvenient to carry, enabling rapid fixing and disassembly of the paint can 101, significantly improving the efficiency of replacing the paint can 101 and reducing downtime. It should be noted that the nut can also be other types of nuts, such as hexagonal nuts or other types of nuts.

[0034] In some embodiments, both the fixed plate 53 and the movable plate 51 have arc-shaped grooves (not shown in the figure) on their opposite sides, and the paint can 101 is disposed between the arc-shaped grooves. The shape of the arc-shaped grooves matches the cylindrical body of a common paint can 101, allowing for surface contact (rather than point or line contact) with the surface of the paint can 101. This increases the contact area during clamping, disperses clamping force, and prevents excessive local pressure from deforming the paint can 101. It also makes it more difficult for the paint can 101 to wobble within the groove, especially during tilting or flipping operations, effectively preventing the paint can 101 from slipping and ensuring stability during the painting process. The curved structure of the arc-shaped grooves can buffer the impact force during clamping, preventing the sharp edges of the fixed plate 53 and the movable plate 51 from directly pressing against the surface of the paint can 101 (especially for plastic paint cans), reducing the probability of scratches, dents, or even cracks on the can body. Simultaneously, the surface contact method reduces localized wear on the paint can 101 due to long-term use, extending its service life.

[0035] In some embodiments, both the fixed plate 53 and the movable plate 51 have anti-slip textures (not shown in the figure) at their arc-shaped grooves. These anti-slip textures significantly increase the friction between the arc-shaped groove and the surface of the paint can 101 by increasing the contact roughness. This effectively prevents the paint can 101 from slipping or shifting within the arc-shaped groove, even during tilting, vibration, or frequent movement. Especially for smooth plastic paint cans 101 or cans with a small amount of paint on them (which are prone to slipping), the anti-slip textures create an interlocking fixation, ensuring the paint can 101 remains in a stable clamping state and preventing spraying position deviations caused by can slippage. The concave-convex structure of the anti-slip textures disperses local pressure during clamping, reducing direct pressure from the arc-shaped groove on the surface of the paint can 101 and lowering the risk of indentations or deformation of the can (especially for thin-walled metal or plastic cans). Simultaneously, the anti-slip textures reduce hard friction between the paint can 101 and the groove, reducing wear caused by long-term use and extending the service life of both the tool and the paint can 101.

[0036] In some embodiments, the spray painting tool further includes a support rod 8, which is vertically and fixedly disposed above the fixed rod 1. One end of the pressure plate 4 is rotatably connected to the end of the support rod 8 away from the fixed rod 1. The support rod 8 raises the pivot point of the pressure plate 4 above the fixed rod 1, so that the pressure plate 4 forms a downward inclined force application angle, which is more matched with the pressing direction of the spray button of the paint can 101 (usually vertically downward), allowing the pressure of the pressure plate 4 on the spray button to be more direct and reducing the loss of force component.

[0037] In some embodiments, the painting tool further includes a support rod 6 and a rotating wheel 7. The support rod 6 is vertically and fixedly disposed above the fixed rod 1 and located between the locking member 5 and the support rod 8. The rotating wheel 7 is rotatably connected to the end of the support rod 6 away from the fixed rod 1, and there is a through space between the rotating wheel 7 and the fixed rod 1. The connecting member 2 can pass through the fixed rod 1 and the through space to connect the pressure plate 4 and the operating wrench 3, and the connecting member 2 can fit against the rotating wheel 7. The rotating wheel 7 precisely guides the force direction of the connecting member 2 by rolling contact with the connecting member 2. At the same time, rolling friction has less resistance than sliding friction, making it easier for the operator to operate the wrench. Especially during long-term continuous operation, it can significantly reduce hand fatigue, ensure stable pressing pressure, and avoid problems such as unstable pressing of the spray button and intermittent paint spraying caused by poor force transmission.

[0038] In some embodiments, the connector 2 is a rigid component, such as a wire or steel wire. The rigid component itself deforms very little, allowing the wrench force from the operating wrench 3 to be transmitted to the pressure plate 4 with almost no loss. This ensures that the pressure plate 4 simultaneously applies pressure to the paint can 101 spray button the instant the wrench is turned, avoiding delays or attenuation of force transmission caused by stretching or slack in the flexible connector 2 (such as a rope). It should be noted that the connector 2 can also be of other types of structure, as long as it does not easily elongate under tension.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
