Description

Technical Field

[0001] This utility model relates to the field of painting equipment, and in particular to a painting device for steel structures. Background Technology

[0002] In applications of steel structures, including the framework of large buildings and the main support of bridges, steel structures are widely used due to their high strength and ease of construction. Painting steel structures is a crucial step in ensuring their durability and extending their service life.

[0003] Currently, painting steel structures is typically done via a paint hose. However, the diverse applications of steel structures, varying painting environments, and different structural dimensions present challenges. In practice, workers must hold a spray gun and move around the steel structure to apply the paint. During this process, workers must monitor the painting effect and continuously adjust the position of the spray hose at the connection point to the spray gun to ensure continuous and uniform painting.

[0004] Existing paint spray guns lack effective securing mechanisms and cannot be firmly attached to a worker's wrist, which is particularly problematic when performing touch-up painting at heights. If a worker accidentally lets go of the paint gun, the spray gun may fall, potentially damaging the equipment and posing a serious safety threat to people and property below. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by using a combination of binding, snap-fit, and locking components to securely fasten the paint guide tube to the operator's wrist. When painting steel structures at heights or in complex environments, even if the hand accidentally slips out, the paint guide tube will not fall, effectively preventing equipment damage and safety threats to personnel and objects below that could result from a falling paint guide tube, thus providing reliable safety assurance for painting operations.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution to the problem of existing paint spray tubes easily falling off.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] Preferably, the binding component includes a left binding strip and a right binding strip that overlap each other. The inner surface of the left binding strip is provided with a rough surface, and the inner surface of the right binding strip is provided with a hook surface. The left binding strip forms a closed loop structure by bonding the rough surface and the hook surface together.

[0015] Preferably, the inner surfaces of the left and right binding straps are provided with an anti-slip inner convex layer, and the surface of the inner convex layer has a wavy concave-convex structure.

[0016] Preferably, the fastener includes a main sleeve and several secondary sleeves, with the secondary sleeves corresponding to both ends of the main sleeve. The main sleeve and secondary sleeves are adapted to the paint guide pipe fitting and can be fitted onto the outside of the paint guide pipe fitting.

[0017] Preferably, both the main card sleeve and the sub-card sleeve have an inner protective layer on their inner walls.

[0018] Preferably, the main card sleeve and the sub-card sleeve are connected by a plug-in assembly. The plug-in assembly includes a plug-in block and a plug-in slot. The plug-in block is connected to one end of the outer wall of the main card sleeve and the sub-card sleeve, and the plug-in slot is opened at the other end of the outer wall of the main card sleeve and the sub-card sleeve, and the plug-in slot is used to engage the plug-in block.

[0019] Preferably, the plug block is elastic and in a state of mutual compression with the inner wall of the plug groove.

[0020] Preferably, the locking component includes a first connecting plate fixedly connected to the buckle component and a second connecting plate connected to the binding component.

[0021] Preferably, the second connecting plate has a slot, and the first connecting plate is inserted into the slot of the second connecting plate.

[0022] Preferably, the second connecting plate is connected to the binding member through a sleeve and a connector. One end of the connector is connected to the left binding band and the other end is connected to the right binding band. The sleeve is fitted over the outside of the connector, and the other end of the sleeve is connected to the second connecting plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The steel structure painting device provided in this application securely fixes the paint guide tube to the operator's wrist through the coordinated action of binding components, buckles, and locking components. When painting steel structures at heights or in complex environments, even if the hand accidentally slips out, the paint guide tube will not fall, effectively preventing equipment damage and safety threats to personnel and objects below that could result from a falling paint guide tube, thus providing reliable safety assurance for painting operations.

[0025] Enhanced ease of use: The left and right binding straps of the fastener can be flexibly adjusted according to wrist size, and the bonding method between the rough and hook surfaces is simple and convenient, allowing for quick and easy wearing and securing. Meanwhile, the main and auxiliary clips of the buckle are connected by elastic plug blocks and slots, allowing for free combination and installation according to the length of the paint guide tube, making operation convenient and adaptable to different working conditions.

[0026] Improved work efficiency: The stable and fixed structure allows the painter to focus more on the painting operation without having to constantly pay attention to the status of the paint guide tube during the operation. It reduces distractions and pauses caused by worrying about the paint guide tube falling, making the painting process smoother and thus improving overall work efficiency.

[0027] Ensuring painting quality: Painters can more easily control parameters such as spraying speed, angle, and pressure, avoiding the impact of shaking or instability of the paint guide tube on the painting effect. This helps to achieve more uniform and accurate painting, improves the painting quality of steel structures, and thus ensures the durability and aesthetics of steel structures.

[0028] Protecting the paint guide pipe fittings: The inner protective layer of the inner wall of the fastener is usually made of soft and wear-resistant materials, such as rubber. During the process of fixing the paint guide pipe fittings, it can effectively protect the outer wall of the paint guide pipe fittings, prevent them from being scratched and damaged during use, extend the service life of the paint guide pipe fittings, and reduce equipment maintenance costs.

Example

[0042] Please see Figure 1-7 A steel structure painting device, comprising:

[0043] Painting device body 1;

[0044] Paint guide tube 2, the first end of which is connected to the body 1 of the painting device;

[0045] The binding part 3 is located at the second end of the paint guide tube 2 and is used to fix the operator's wrist.

[0046] Fastener 4 is fitted onto the outside of paint guide tube 2;

[0047] Locking element 5 connects the binding element 3 and the snap-fit ​​element 4. Locking element 5 includes an adjustable threaded locking structure.

[0048] The steel structure painting device of this application is mainly composed of a painting device body 1, a paint guide pipe 2, a binding component 3, a buckle component 4, a locking component 5, a sleeve frame 6, and a connecting component 306. The following is a detailed description of its structure and working principle.

[0049] I. Detailed Structure and Connection Methods of Each Component

[0050] Installation and Adjustment of Binding Component 3: Wrap the left binding strap 301 and right binding strap 303 around the operator's wrist. Since the inner surface of the left binding strap 301 has a rough surface 302 and the inner surface of the right binding strap 303 has a hook surface 304, the rough surface 302 and the hook surface 304 are bonded together to form a closed-loop structure. The left binding strap 301 and right binding strap 303 have a certain width, which increases the contact area with the wrist and ensures the stability of the fixation. For operators with different wrist sizes, the bonding length of the rough surface 302 and the hook surface 304 can be adjusted according to the actual situation to meet the applicability. At the same time, the non-contact ends of the left binding strap 301 and right binding strap 303 have an anti-slip inner convex layer 305, whose surface has a wavy, uneven structure and is made of rubber. When the binding component 3 comes into contact with the wrist or clothing around the wrist, the anti-slip inner convex layer 305 can further increase the stability of the fixation and prevent the binding component 3 from sliding on the wrist.

[0051] Installation and adjustment of fastener 4: Select an appropriate number of auxiliary clamps 405 according to the length of the paint guide tube 2 and actual usage requirements. If the paint guide tube 2 is not too long, simply place the main clamp 401 on the outside of the paint guide tube 2 at a suitable position. The main clamp 401 is mainly used to connect the binding component 3. If the paint guide tube 2 is too long, the excessive length can be bent and folded to fix it by adding or removing auxiliary clamps 405. The auxiliary clamps 405 are placed at the two ends of the main clamp 401. The inner walls of both the main clamp 401 and the auxiliary clamps 405 are provided with an inner protective layer 404 made of rubber. When clamping the corresponding position of the paint guide tube 2, the inner protective layer 404 comes into contact with the outer wall of the paint guide tube 2, which can increase the friction of the contact surface, prevent the fastener 4 from sliding on the paint guide tube 2, and also protect the paint guide tube 2. The main sleeve 401 and the secondary sleeve 405 are connected by a plug-in assembly, which includes a plug-in block 402 and a plug-in groove 403. The plug-in block 402 is connected to one end of the outer wall of the main sleeve 401 and the secondary sleeve 405, and the plug-in groove 403 is formed at the other end of the outer wall of the main sleeve 401 and the secondary sleeve 405. During assembly, the plug-in block 402 of the secondary sleeve 405 is inserted into the plug-in groove 403 of the main sleeve 401. Because the plug-in block 402 is elastic, it creates an interference fit with the inner wall of the plug-in groove 403. The number of secondary sleeves 405 can be selected according to the usage requirements to fix the paint guide tubes 2 of different lengths.

[0052] Locking component 5 installation and connection: The first connecting plate 501 is fixedly connected to the buckle 4, and the second connecting plate 502 is connected to the binding component 3 through the sleeve 6 and the connector 306. One end of the connector 306 is connected to the left binding strap 301, and the other end is connected to the right binding strap 303. The sleeve 6 is fitted over the connector 306, and the other end of the sleeve 6 is connected to the second connecting plate 502. The first connecting plate 501 has positioning posts 503 with external threads at its four corners. The second connecting plate 502 has through holes that fit with the positioning posts 503 with clearance, and the second connecting plate 502 has slots. During installation, the first connecting plate 501 is inserted into the slot of the second connecting plate 502, and the positioning pin 503 is passed through the through hole of the second connecting plate 502. A locking nut 504 is screwed onto the end of the positioning pin 503. By tightening the locking nut 504, the first connecting plate 501 and the second connecting plate 502 are fixed together, thus connecting the binding member 3 and the snap-fit ​​member 4. When separation is required, the locking nut 504 is reversed to disengage it from the end of the positioning pin 503, releasing the fixation on the positioning pin 503. At this time, moving the first connecting plate 501 will bring the positioning pin 503 out of the through hole of the second connecting plate 502, allowing for separation and ensuring convenient assembly and disassembly.

[0053] II. Working Principle

[0054] Before painting the steel structure, the painter must first adjust the fastener 3 according to their wrist size. Wrap the left fastener 301 and right fastener 303 around the wrist, adjusting the fit between the rough surface 302 and the hook surface 304 to ensure the fastener 3 is comfortably and securely fixed to the wrist. At this point, the inner convex layer 305 comes into play; its uneven surface increases friction with the wrist or clothing, effectively preventing the fastener 3 from slipping on the wrist and providing a stable foundation for the subsequent connection of the paint guide tube 2.

[0055] Next, the painter needs to install the clips 4 according to the actual length of the paint guide tube 2. If the paint guide tube 2 is short, only the main clip 401 needs to be used. Simply slip the main clip 401 onto the paint guide tube 2 at a suitable position near the wrist. If the paint guide tube 2 is long, to prevent it from shaking or tangling during operation and affecting the painting work, the painter needs to select an appropriate number of auxiliary clips 405. Align the insertion block 402 at one end of the auxiliary clip 405 with the insertion slot 403 on the main clip 401 or the already connected auxiliary clip 405, and insert it forcefully. Because the insertion block 402 is elastic, it will be tightly pressed against the inner wall of the insertion slot 403 after insertion, forming a stable connection. Then, the assembled buckle 4 is put onto the paint guide tube 2. The inner protective layer 404 is in close contact with the outer wall of the paint guide tube 2. On the one hand, it increases the friction, making it difficult for the buckle 4 to slide on the paint guide tube 2. On the other hand, the inner protective layer 404 is usually made of soft and wear-resistant materials, such as rubber, which can effectively protect the outer wall of the paint guide tube 2 and prevent it from being scratched and damaged during use.

[0056] Next, the painter begins connecting the locking piece 5, aligning the positioning pin 503 on the first connecting plate 501 with the through hole on the second connecting plate 502, and slowly inserting it to ensure that the first connecting plate 501 is accurately inserted into the groove of the second connecting plate 502. The fit between the groove and the first connecting plate 501 further enhances the stability of the connection, preventing relative displacement between the two in the horizontal direction. Then, using a tool such as a wrench, the locking nut 504 is screwed onto the positioning pin 503, gradually tightening it to ensure a tight fit between the first connecting plate 501 and the second connecting plate 502, thereby firmly connecting the buckle 4 and the binding piece 3 together, and thus stably fixing the paint guide tube 2 to the wrist.

[0057] In actual spray painting operations, the operator holds the spray painting device body 1 to perform the spray painting operation. Because the binding part 3 is securely fixed to the wrist, the buckle part 4 is tightly connected to the paint guide tube 2, and the locking part 5 firmly connects the two, even if the operator's hand moves frequently or changes position, the paint guide tube 2 can always stably follow the wrist movement and will not easily fall off. This allows the operator to focus more on the spray painting work, such as controlling the speed, angle, and pressure of the spray, thereby improving the uniformity and accuracy of the spray, and increasing work efficiency and spray quality. At the same time, this stable connection structure greatly reduces the risk of the paint guide tube 2 falling off, ensuring the safety of the spray painting operation at heights or in complex environments, and effectively avoiding accidents such as equipment damage and personal injury that may be caused by the paint guide tube 2 falling off.

[0058] Through the coordinated operation of the above components, the steel structure painting device of this utility model effectively solves the problem of existing paint spraying pipes easily falling off, and improves the safety and efficiency of steel structure painting operations.

[0059] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
