Description

Technical Field

[0001] The present invention relates to the technical field of fishing gear, in particular to a portable carbon fiber fishing table top panel. Background Art

[0002] A fishing platform is a fishing auxiliary tool, which is a portable and movable table, providing fishing enthusiasts with a flat and comfortable operation platform for placing a fishing box even in the case of complex terrain. When in use, it is supported on the shore or the water surface of the shore. The angler sits on this fishing platform or sits on this fishing platform through a seat to fish. It generally has support feet and a platform board surface, and some fishing platforms can also be folded into a box body for convenient carrying.

[0003] The existing portable carbon fiber fishing table is a folding fishing table formed by splicing two table top panels. This table top panel is formed by a carbon fiber blow molding process. In order to ensure the strength of the table top panel and reduce costs, the table top panel is generally made into an integrated combined structure consisting of a panel combined with a hollow cavity frame beam with a Chinese character "ri" shaped reinforcing rib. This hollow cavity frame beam with a Chinese character "ri" shaped reinforcing rib is an integrated frame beam structure with a through cavity formed by combining two short transverse cavities and three long longitudinal cavities. During preparation, an air bag needs to be placed into the two short transverse cavities and the three long longitudinal cavities, and then the air bag is inflated to form the cavity frame beam. However, in actual production, due to the complexity of the cavity body, the air bag is very easy to explode and leak air, resulting in the failure of inflation, the appearance of defective products, serious waste of materials, and an increase in production costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a carbon fiber table top formed by combining a hollow cavity frame beam with a Chinese character "kou" shaped and a foamed solid cross bar beam and then combining with a panel, so as to avoid the situation that the air bag is easy to explode and leak air, thereby improving the qualified rate.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is a portable carbon fiber fishing platform table top, including an integrally formed carbon fiber panel and a carbon fiber frame beam, the carbon fiber frame beam includes an integrally formed U-shaped hollow cavity frame beam and a straight solid cross bar beam, the U-shaped hollow cavity frame beam includes two short cross cavities and two long longitudinal cavities connected end to end and internally connected, the straight solid cross bar beam is one, two or more cross bars, which are formed by foaming an expanded material wrapped with carbon fiber; the straight solid cross bar beams are all The carbon fiber frame beam is evenly distributed and connected in the U-shaped hollow cavity frame beam; in this way, the U-shaped hollow cavity frame beam can be formed by the air blowing process. Since the two short transverse cavities and the two long longitudinal cavities of the U-shaped hollow cavity frame beam are connected end to end and are internally connected, the air bag can be a single strip through the U-shaped hollow cavity without any branches. It is no longer prone to explosion and leakage during the blowing process. The I-shaped solid cross beam adopts foam material and does not require blowing. The yield rate of the carbon fiber fishing platform table top made in this way is very high.

[0006] Furthermore, the cross-sectional structure and area of ​​the short transverse cavity and the long longitudinal cavity are the same, so the cross-section of the airbag is also the same, which can further improve the yield rate.

[0007] The thickness of the I-shaped solid transverse beam is 5%-100% of the thickness of the long longitudinal cavity.

[0008] Furthermore, it is preferred that the thickness of the I-shaped solid transverse beam is 30% of the thickness of the long longitudinal cavity.

[0009] The expansion material can be PU black and white material, high energy glue, polyethylene, epoxy foam or other foamable materials.

[0010] The method for preparing the portable carbon fiber fishing platform table top comprises the following steps:

[0011] ⑴ Stack and roll the cut carbon fiber materials on a square core mold consisting of two short core molds and two long core molds.

[0012] ⑵ After rolling, take out the core mold to obtain a U-shaped hollow cavity blank, and then insert the air bag preform.

[0013] ⑶ Place the preformed U-shaped hollow cavity blank into the U-shaped cavity in the lower mold.

[0014] ⑷ Seal the air nozzle, insert the air nozzle into the air bag, and then wrap it tightly with paper tape.

[0015] (5) Stack the cut carbon fiber materials and roll the expansion material into the carbon fiber materials to obtain a straight-line solid cross beam blank.

[0016] ⑹ Place the I-shaped solid cross beam blank into the I-shaped mold cavity in the lower mold.

[0017] ⑺The cut carbon fiber materials for making panels are stacked and laid on the lower mold, the U-shaped hollow cavity blank and the I-shaped solid cross beam blank.

[0018] ⑻ Place the upper mold cover on the lower mold.

[0019] ⑼ Molding, confirm the temperature, pressure and technical parameters of the hot pressing furnace, and pass through 150-160℃ high temperature, 12kg / cm 2 Air pressure, 45 minutes for molding and curing.

[0020] ⑽ Demolding, open the mold and take out the product, and take out the embedded parts in the U-shaped cavity to obtain an integrated portable carbon fiber fishing platform table top composed of a carbon fiber panel, a U-shaped hollow cavity frame beam and a straight solid cross beam.

[0021] In this way, the air blowing molding process and the compression molding process are combined to form the carbon fiber panel, the U-shaped hollow cavity frame beam and the I-shaped solid cross beam into one piece to make a portable carbon fiber fishing platform table top, which can avoid the air bag explosion and leakage and effectively improve the yield rate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] ⑴ The tabletop of the portable carbon fiber fishing platform is made into an integrated structure consisting of a carbon fiber panel, a U-shaped hollow cavity frame beam and a I-shaped solid cross beam. This makes it easy to prepare it by combining the blow molding process with the compression molding process, which can avoid the air bag explosion and leakage and effectively improve the yield rate.

[0024] ⑵ Make the cross-sectional structure and area of ​​the short transverse cavity and the long longitudinal cavity in the U-shaped hollow cavity frame beam the same, so that the cross-sectional area of ​​the inflatable air bag is consistent throughout the entire process, and the expansion and curing force at each position of the inner cavity is the same, which can effectively improve the quality of the product and increase the yield rate.

[0030] The following further illustrates the present invention in conjunction with embodiments. The following embodiments are intended to illustrate the present invention rather than further limit the present invention, and the protection scope of the present invention should not be limited thereby.

[0031] Embodiment 1 is the structure and preparation method of the existing portable carbon fiber fishing table top.

[0032] As Figure 3 、 4 shown, the existing portable carbon fiber fishing table top includes an integrally formed carbon fiber panel 1 and a carbon fiber frame beam 2. The carbon fiber frame beam 2 is an integrally formed rectangle-shaped hollow cavity frame beam 7. The rectangle-shaped hollow cavity frame beam 7 includes two short horizontal cavities 5 and three long vertical cavities 6 that are connected end to end, communicate in the middle, and are internally through. The middle vertical cavity among the three long vertical cavities 6 is called the intermediate beam 8. The cross-sectional area of the long vertical cavity 6 is smaller than the cross-sectional area of the short horizontal cavity 5.

[0033] Its preparation method includes the following steps:

[0034] ⑴ Stack and roll the cut carbon fiber materials on a rectangle-shaped core mold composed of two short core molds and three long core molds.

[0035] ⑵ After rolling, take out the core mold to obtain a rectangle-shaped hollow cavity blank, and then insert an air bag for preforming.

[0036] ⑶ Place the preformed rectangle-shaped hollow cavity blank into the rectangle-shaped mold cavity in the lower mold.

[0037] ⑷ Seal the air nozzle, insert the air nozzle into the air bag, and then wrap it tightly with paper tape.

[0038] ⑸ Stack and lay the cut carbon fiber materials for making the panel on the lower mold and the rectangle-shaped hollow cavity blank.

[0039] ⑹ Cover the upper mold on the lower mold.

[0040] ⑺ Molding, confirm the temperature, air pressure and other technical parameters of the hot pressing furnace platform, and carry out molding and curing at a high temperature of 150 - 160 °C, an air pressure of 12 kg / cm 2 for 45 minutes.

[0041] ⑻ Demold, open the mold to take out the product, and take out the internal embedment in the "曰"-shaped cavity, then a one-piece portable carbon fiber fishing table top panel composed of a carbon fiber panel and a "曰"-shaped hollow cavity frame beam can be obtained.

[0042] In this method, since there are three hollow long longitudinal cavities 6 and two short transverse cavities 5 in the "曰"-shaped hollow cavity 7, the airbag must pass through three hollow long longitudinal cavities 6 and two short transverse cavities 5 simultaneously. For the airbags in the two short transverse cavities 5, one side wall of each airbag will pass through the cavity intersection where the two ends of the middle beam 8 are located. The side wall of the airbag in the short transverse cavity 5 at the cavity intersection position has no support from the short transverse cavity side wall. When inflating, when the gas in the airbag runs to the cavity intersection position of the middle beam, if the previous airbag is slightly blocked, the gas will run towards the cavity intersection position between the short transverse cavity 5 and the middle beam 8. When the airbag expands beyond the pressure it can withstand, there is no force to resist it at the cavity intersection position of the middle beam, and the airbag will explode and leak air; after being fully inflated, the airbag at this position is also prone to explosion and air leakage. Therefore, when using this desktop structure and production method, there are often cases of blowing failure and defective products, seriously affecting the yield rate. At the same time, due to the existence of the middle beam 8 in the three long longitudinal cavities 6, there will be a smooth board strip in the center of the front of the desktop, which also affects the appearance.

[0043] Embodiment 2 is about the structure and preparation method of the portable carbon fiber fishing table top panel of this solution.

[0044] As Figure 1 、 2 shown, a portable carbon fiber fishing table top panel provided by this solution includes an integrally formed carbon fiber panel 1 and a carbon fiber frame beam 2. The carbon fiber frame beam 2 includes an integrally formed "口"-shaped hollow cavity frame beam 3 and an "一"-shaped solid core cross beam 4. The "口"-shaped hollow cavity frame beam 3 includes two short transverse cavities 5 and two long longitudinal cavities 6 that are connected end to end and internally through. The cross-sectional structures and areas of the short transverse cavity 5 and the long longitudinal cavity 6 are the same. The "一"-shaped solid core cross beam 4 is two cross beams, and one cross beam or multiple cross beams can be made according to requirements. It is formed by carbon fiber wrapping and expanding material foaming. The expanding material is high-energy glue. The thickness of the "一"-shaped solid core cross beam 4 is 5% - 100% of the thickness of the long longitudinal cavity 6. Here, the thickness of the "一"-shaped solid core cross beam 4 is made 30% of the thickness of the long longitudinal cavity 6. The "一"-shaped solid core cross beam 4 is evenly distributed and connected inside the "口"-shaped hollow cavity frame beam 3 to form the carbon fiber frame beam 2.

[0045] The preparation method of the portable carbon fiber fishing table top panel includes the following steps:

[0046] ⑴ Stack and roll the cut carbon fiber materials on a "口"-shaped core mold composed of two short core molds and two long core molds.

[0047] ⑵ After rolling, take out the core mold to obtain a U-shaped hollow cavity blank, and then insert the air bag preform.

[0048] ⑶ Place the preformed U-shaped hollow cavity blank into the U-shaped cavity in the lower mold.

[0049] ⑷ Seal the air nozzle, insert the air nozzle into the air bag, and then wrap it tightly with paper tape.

[0050] (5) Stack the cut carbon fiber materials and roll the expansion material into the carbon fiber materials to obtain a straight-line solid cross beam blank.

[0051] ⑹ Place the I-shaped solid cross beam blank into the I-shaped mold cavity in the lower mold.

[0052] ⑺The cut carbon fiber materials for making panels are stacked and laid on the lower mold, the U-shaped hollow cavity blank and the I-shaped solid cross beam blank.

[0053] ⑻ Place the upper mold cover on the lower mold.

[0054] ⑼ Molding, confirm the temperature, pressure and technical parameters of the hot pressing furnace, and pass through 150-160℃ high temperature, 12kg / cm 2 Air pressure, 45 minutes for molding and curing.

[0055] ⑽ Demolding, open the mold and take out the product, and take out the embedded parts in the U-shaped cavity to obtain an integrated portable carbon fiber fishing platform table top composed of a carbon fiber panel 1, a U-shaped hollow cavity frame beam 3 and a straight solid cross beam 4.

[0056] In this way, the blow molding process and the compression molding process are combined to form a carbon fiber panel 1, a U-shaped hollow cavity frame beam 3, and a straight solid cross beam 4 into an integrated form to form a portable carbon fiber fishing table top. Because the U-shaped hollow cavity frame beam 3 is a directly connected cavity, the air bag only needs to make a single circle to pass through it, and there is no cavity intersection formed by the intermediate beam. The air bag is supported by the side walls throughout, and the air bag will no longer explode and leak. At the same time, the cross-section of the same area makes the air bag flow more smoothly during the entire blowing process, and the air bag does not need to pass through the cavity intersection formed by the intermediate beam and the cross beam, which greatly improves the yield rate. At the same time, there is no bare strip in the center of the front of the table, which is more aesthetically pleasing.
