[0002] In the production of fiberglass products, gel coat spraying is a crucial process, directly affecting the appearance, corrosion resistance, and overall performance of the products. Currently, most existing fiberglass gel coat spraying devices on the market use a single spray gun. The spray area of ​​a single gun is relatively narrow. When facing a large spraying area, the sprayer needs to repeatedly spray multiple times with the gun to complete the coating of the entire surface. This repeated spraying significantly extends the operation time and reduces production efficiency. Therefore, we have made improvements and proposed a fiberglass gel coat spraying device.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-6A fiberglass gelcoat spraying device includes a first spray gun 1 and a second spray gun 2 arranged side by side with the first spray gun 1. A first connecting structure 3 is provided between the first spray gun 1 and the second spray gun 2 to connect the first spray gun 1 and the second spray gun 2. Both the first spray gun 1 and the second spray gun 2 have triggers 5. A second connecting structure 4 is provided between the two triggers 5 to achieve synchronous operation of the two triggers 5. The second connecting structure 4 includes a first connecting tube 401 and a second connecting tube 403. The ends of the first connecting tube 401 and the second connecting tube 403 that are far apart from each other are respectively connected to the first spray gun 1 and the second spray gun. 2. A connecting rod 402 is inserted between the first connecting pipe 401 and the second connecting pipe 403, and a limiting component is provided on the first connecting pipe 401 to limit the movement of the connecting rod 402; the first spray gun 1 and the second spray gun 2 are arranged side by side, which can expand the area of ​​a single spray when facing a large area of ​​spraying, reduce the number of times the sprayer has to spray repeatedly, thereby shortening the operation time and improving the spraying efficiency of fiberglass gel coat; the first spray gun 1 and the second spray gun 2 can also be used separately. When spraying a small area, the operator can select one of the spray guns according to the actual needs to achieve spraying of a small area and avoid waste of gel coat material; The first glue spray gun 1, the second glue spray gun 2, and the trigger 5 are all existing components that can be purchased directly from the market. Their specific structures and principles are existing technologies and will not be described in detail in this application.

[0020] The first glue gun 1 and the second glue gun 2 use the same glue gun. Since different models of glue guns have different glue spraying areas, after selecting the appropriate model of glue gun, the distance between the first glue gun 1 and the second glue gun 2 is determined according to its glue spraying area. Then, the length of the first connecting structure 3 and the second connecting structure 4 is determined according to the distance. In this way, it is confirmed that the distance between the first glue gun 1 and the second glue gun 2 can meet the usage requirements.

[0021] Furthermore, the limiting component includes a side plate 404 fixedly connected to the first connecting pipe 401. A groove 406 is provided between the side plate 404 and the first connecting pipe 401. A second threaded rod 405 is slidably connected in the groove 406. One end of the second threaded rod 405 is fixedly connected to the connecting rod 402. A second internal threaded tube 407 is threadedly connected to the outer surface of the second threaded rod 405. One end of the second internal threaded tube 407 contacts the side of the side plate 404. When the second internal threaded tube 407 is tightened, it abuts against the side plate 404, thereby fixing the position of the connecting rod 402 to improve the stability when the connecting rod 402 is inserted into the second connecting pipe 403. Loosening the second internal threaded tube 407 can release the fixation, thereby moving the second threaded rod 405 and the connecting rod 402 by pushing the second internal threaded tube 407 to realize the insertion or separation of the connecting rod 402 and the second connecting pipe 403.

[0022] Furthermore, the first connecting structure 3 includes an insert rod 301 and a first threaded rod 305, which are respectively connected to the first glue gun 1 and the second glue gun 2. The insert rod 301 is fitted with a first internal threaded tube 306 near the first threaded rod 305, and the first internal threaded tube 306 is threadedly connected to the outer surface of the first threaded rod 305, so that the first internal threaded tube 306 and the first threaded rod 305 can be disassembled and assembled.

[0023] Furthermore, a retaining ring 302 is fixedly connected to one end of the insert rod 301 near the first internally threaded tube 306, and the retaining ring 302 contacts the inner wall of the first internally threaded tube 306. The inner diameter of the end of the first internally threaded tube 306 near the first glue gun 1 is smaller than the inner diameter of the end away from the first glue gun 1, so that a limiting relationship can be formed between the first internally threaded tube 306 and the retaining ring 302.

[0024] Furthermore, a positioning element is provided between the insertion rod 301, the retaining ring 302, and the first threaded rod 305. The positioning element includes a limiting groove 303 formed between the insertion rod 301 and the retaining ring 302. A limiting rod 304 is inserted into the inner wall of the limiting groove 303, and one end of the limiting rod 304 is fixedly connected to the first threaded rod 305. The cross-sections of the limiting groove 303 and the limiting rod 304 are both non-circular, such as hexagonal. This arrangement allows the limiting groove 303 and the limiting rod 304 to limit the distance between the insertion rod 301 and the first threaded rod 305 after they are inserted, so as to prevent relative rotation between the limiting groove 303 and the limiting rod 304.

[0025] Furthermore, a first reinforcing ring 307 is provided at the connection between the insert rod 301 and the first glue gun 1. The first reinforcing ring 307 is used to reinforce the connection between the first glue gun 1 and the insert rod 301 to improve stability.

[0026] Furthermore, a second reinforcing ring 308 is provided at the connection between the first threaded rod 305 and the second glue gun 2. The second reinforcing ring 308 is used to reinforce the connection between the second glue gun 2 and the first threaded rod 305 to improve stability.

[0027] The insertion rod 301 is welded together with the retaining ring 302 and the first reinforcing ring 307. The first reinforcing ring 307 and the insertion rod 301 are welded together with the first glue gun 1. The first threaded rod 305, the second reinforcing ring 308 and the second glue gun 2 are welded together. The first threaded rod 305 is welded together with the limiting rod 304. The first connecting pipe 401 is welded together with the side plate 404 and the first glue gun 1. The second connecting pipe 403 is welded together with the second glue gun 2. The second threaded rod 405 is welded together with the connecting rod 402. All components connected by welding are made of weldable materials, such as stainless steel.

[0028] Furthermore, hooks 6 are provided at the top of both the first glue gun 1 and the second glue gun 2. The hooks 6 facilitate the hanging of the first glue gun 1 and the second glue gun 2 on the existing support frame.

[0029] The usage process of the fiberglass gel coat spraying device provided by this utility model is as follows: Referring to the figure, hold the first glue gun 1 or the second glue gun 2 and pull the corresponding trigger 5. The second connecting structure 4 enables the two triggers 5 to move synchronously so that the first glue gun 1 and the second glue gun 2 can spray glue at the same time. When the trigger 5 is released, the first glue gun 1 and the second glue gun 2 stop spraying glue. If spraying a small area for a short time, loosen the second internal thread tube 407 and push the second internal thread tube 407 away from the second connecting tube 403. The second internal thread tube 407 drives the connecting rod 402 to separate from the second connecting tube 403 through the second threaded rod 405. At this time, when the trigger 5 is pulled, only the pulled trigger 5 moves, while the other trigger 5 remains stationary. Thus, the first glue gun 1 or the second glue gun 2 can be used alone for spraying. After inserting the connecting rod 402 into the second connecting tube 403 and tightening the second internal thread tube 407, the two triggers 5 can be connected together again. When the connecting rod 402 is separated from the second connecting tube 403, the first internal thread tube 306 is rotated to separate the first internal thread tube 306 from the first threaded rod 305, thus separating the first glue gun 1 and the second glue gun 2. This allows for the long-term use of either the first glue gun 1 or the second glue gun 2 to spray small areas. After inserting the limiting rod 304 into the limiting groove 303, the first internal thread tube 306 and the first threaded rod 305 are screwed together. Then, the connecting rod 402 is inserted into the second connecting tube 403 to connect the first glue gun 1 and the second glue gun 2 together.
