Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber products, in particular to a wear-resistant carbon fiber tube. Background Art

[0002] The main raw materials for wear-resistant carbon fiber tubes include carbon fiber yarn and pre-impregnated resin. Carbon fiber yarn, with its high strength and high modulus, is the primary material for the carbon fiber tube skeleton. It is a tubular composite material manufactured through advanced bonding technology and scientific production processes.

[0003] After searching, the utility model with Chinese patent announcement number CN104924677B discloses a carbon fiber tube, including a carbon fiber module layer, a basalt fiber module layer and a carbon fiber cloth layer wrapped from the inside to the outside. The basalt fiber module layer includes at least two layers of basalt fiber cloth layers, and the carbon fiber bundles of the carbon fiber cloth layer are staggered to form a staggered mesh.

[0004] The above-mentioned device achieves the purpose of improving the aesthetics of the pipe by setting the carbon fiber layer as the outermost layer. Although the carbon fiber material has high wear resistance, when it is put into use, if the pipe is subjected to friction for a long time, it will still be damaged, and then the entire pipe will not be able to be used, which is a waste of resources. Utility Model Content

[0005] The purpose of the present invention is to provide a wear-resistant carbon fiber tube to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant carbon fiber tube, comprising a carbon fiber layer, two protective components installed on the outside of the carbon fiber layer, the two protective components completely wrapping the carbon fiber layer, the protective component comprising a protective sheet and a tensioning sheet wrapped around the outside of the carbon fiber layer, the protective sheet being at the bottom of the tensioning sheet, a connecting card being provided at both ends of the tensioning sheet, two limiting grooves being provided on the bottom outer wall of the protective sheet, and the two connecting cards being slidably inserted into the two limiting grooves respectively.

[0007] A protective structure can be formed on the outside of the carbon fiber layer, which can replace the carbon fiber layer to withstand friction, which is beneficial to improving the service life of the pipe. It can also be replaced as needed, which is more convenient to use. First, a protective sheet is put on the outside of the carbon fiber layer, and then the connecting card at the end of the tensioning sheet is inserted into the limit groove at the end of the protective sheet. The two will form a whole. At this time, the state of the two is relatively loose. As long as the tensioning sheet is baked at high temperature, it can shrink and shorten due to its special properties when heated. Then the whole formed by the protective sheet and the tensioning sheet will tightly cover the outside of the carbon fiber layer, and then repeat the operation to install another protective component on the outside of the carbon fiber layer. Because this protective component has not been processed and is relatively loose, the connection between the protective sheet and the tensioning sheet will not be hindered by the installation of the protective component.

[0008] As a further preferred embodiment of the present technical solution, a reinforcing component is installed inside the carbon fiber layer, including a limiting ring arranged on the circumferential inner wall of the carbon fiber layer, an inner tube is slidably inserted inside the carbon fiber layer, the inner tube is fitted with the limiting ring, and the groove between the inner tube and the carbon fiber layer is filled with a filling layer.

[0009] As a further preferred embodiment of the present technical solution, a heat insulation layer is provided on the circumferential inner wall of the carbon fiber layer, the heat insulation layer is located outside the filling layer, and the heat insulation layer is made of rock wool material.

[0010] The inner tube is inserted into the carbon fiber layer, and then it will come into contact with the limiting ring to complete the positioning. The filling layer is then sprayed into the cavity formed by the two, and then expanded to completely fill the cavity. This can effectively improve the rigidity and strength of the carbon fiber tube, and can absorb and disperse part of the impact force, thereby protecting the pipe from damage. The thermal insulation layer can play a heat insulation effect to prevent excessive external heat from being transferred to the filling layer and causing damage to it.

[0011] As a further preferred embodiment of the present technical solution, a flange is provided at each end of the carbon fiber layer, and a same positioning assembly is installed between the two flanges.

[0012] As a further preferred embodiment of the present technical solution, the positioning assembly includes two positioning columns fixedly connected to the outer wall of one side of a flange, and a positioning hole adapted for the two positioning columns is opened inside the other flange. A limit pin is slidably inserted inside each of the two positioning columns, and the distance between the limit pin and the flange is greater than the thickness of the flange.

[0013] As a further preferred embodiment of the present technical solution, the protective sheet is made of polycarbonate material, and the tensioning sheet is made of fluorinated ethylene propylene material.

[0014] As a further preferred embodiment of the present technical solution, the carbon fiber layer is composed of carbon fiber filaments and epoxy resin.

[0015] The utility model provides a wear-resistant carbon fiber tube, which has the following beneficial effects:

[0016] (1) The utility model can form a protective structure on the outside of the carbon fiber layer by setting a protective component, which can replace the carbon fiber layer to withstand friction, which is beneficial to improving the service life of the pipe. It can also be replaced as needed, which is more convenient to use. First, a protective sheet is put on the outside of the carbon fiber layer, and then the connecting card at the end of the tensioning sheet is inserted into the limit groove at the end of the protective sheet. The two will form a whole. At this time, the state of the two is relatively loose. As long as the tensioning sheet is baked at high temperature, it can shrink and shorten due to its special properties when heated. Then the whole formed by the protective sheet and the tensioning sheet will tightly cover the outside of the carbon fiber layer. Then repeat the operation to install another protective component on the outside of the carbon fiber layer. Because this protective component has not been processed and is relatively loose, the connection between the protective sheet and the tensioning sheet will not be hindered by the installation of the protective component.

[0017] (2) The present invention provides a reinforcing component, inserts the inner tube into the carbon fiber layer, and then contacts the limiting ring to complete the positioning. Then the filling layer is sprayed into the cavity formed by the two, and then expands to completely fill the cavity. This can effectively improve the rigidity and strength of the carbon fiber tube, and can absorb and disperse part of the impact force, thereby protecting the tube from damage. The heat insulation layer can play a heat insulation effect, preventing excessive external heat from being transferred to the filling layer and causing damage to it.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a wear-resistant carbon fiber tube includes a carbon fiber layer 1, and two protective components 3 are installed on the outside of the carbon fiber layer 1. The two protective components 3 completely wrap the carbon fiber layer 1. The protective component 3 includes a protective sheet 301 and a tensioning sheet 302 wrapped around the outside of the carbon fiber layer 1. The protective sheet 301 is at the bottom of the tensioning sheet 302, and a connecting card 303 is provided at both ends of the tensioning sheet 302. Two limiting grooves are provided on the bottom outer wall of the protective sheet 301, and the two connecting cards 303 are slidably inserted into the two limiting grooves respectively.

[0025] First, a protective sheet 301 is put on the outside of the carbon fiber layer 1, and then the connecting card 303 at the end of the tensioning sheet 302 is inserted into the limiting groove at the end of the protective sheet 301. The two will form a whole. At this time, the state of the two is relatively loose. As long as the tensioning sheet 302 is baked at high temperature, it can shrink and shorten due to its special properties when heated. Then the whole formed by the protective sheet 301 and the tensioning sheet 302 will tightly cover the outside of the carbon fiber layer 1. Then repeat the operation to install another protective component 3 on the outside of the carbon fiber layer 1. Because this protective component 3 has not been processed and is relatively loose, the connection between the protective sheet 301 and the tensioning sheet 302 will not be hindered by the installation of the protective component 3, thereby achieving the effect of protecting the pipe and the texture of the carbon fiber can also be displayed.

[0026] like Figure 3 and Figure 4 As shown, a reinforcing component 4 is installed inside the carbon fiber layer 1, including a limiting ring 401 set on the inner wall of the circumference of the carbon fiber layer 1, and an inner tube 402 is slidably inserted inside the carbon fiber layer 1. The inner tube 402 fits with the limiting ring 401, and the groove between the inner tube 402 and the carbon fiber layer 1 is filled with a filling layer 403.

[0027] The inner circumferential wall of the carbon fiber layer 1 is provided with a heat insulating layer 404 , which is located outside the filling layer 403 and is made of rock wool material having excellent heat insulating and fireproof properties, so that heat will not penetrate at will.

[0028] The inner tube 402 is inserted into the carbon fiber layer 1, and then it will come into contact with the limiting ring 401 to complete the positioning. Then the filling layer 403 is sprayed into the cavity formed by the two, and then expanded to completely fill the cavity. This can effectively improve the rigidity and strength of the carbon fiber tube, and can absorb and disperse part of the impact force, thereby protecting the tube from damage. The heat insulation layer 404 can have a heat insulation effect to prevent excessive external heat from being transferred to the filling layer 403 and causing damage to it.

[0029] like Figure 1and Figure 4 As shown, a flange 2 is provided at each end of the carbon fiber layer 1 , and a same positioning component 5 is installed between the two flanges 2 .

[0030] The positioning assembly 5 includes two positioning columns 501 fixedly connected to the outer wall of one side of the flange 2, and a positioning hole 503 adapted to the two positioning columns 501 is opened inside the other flange 2. A limit pin 502 is slidably inserted inside the two positioning columns 501, and the distance between the limit pin 502 and the flange 2 is greater than the thickness of the flange 2.

[0031] Insert the positioning column 501 on the outside of one flange 2 into the positioning hole 503 of the other pipe, and then overlap the two flanges 2. At this time, the through holes of the two flanges 2 will also correspond one to one, which is convenient for the subsequent locking work. Finally, insert the limit pin 502 into the positioning column 501 to complete the preliminary connection, making the installation process convenient enough.

[0032] like Figure 2 As shown, the protective sheet 301 is made of polycarbonate material, which has excellent impact strength, transparency, heat resistance and wear resistance. The tensioning sheet 302 is made of fluorinated ethylene propylene material, which can be shrunk and shortened by high-temperature heating. It is resistant to a variety of chemicals and has a wide operating temperature range. The transparency is also excellent.

[0033] like Figure 3 As shown, the carbon fiber layer 1 is composed of carbon fiber filaments and epoxy resin. The carbon fiber filaments soaked in resin solution are wound onto a core mold according to a specific method. After a series of treatments, the core mold is removed to obtain a carbon fiber tube.

[0034] The utility model provides a wear-resistant carbon fiber tube, the specific working principle of which is as follows:

[0035] When the device is working, first put a protective sheet 301 on the outside of the carbon fiber layer 1, then insert the connecting card 303 at the end of the tensioning sheet 302 into the limiting groove at the end of the protective sheet 301, and the two will form a whole. At this time, the state of the two is relatively loose. As long as the tensioning sheet 302 is baked at high temperature, it can shrink and shorten due to its special properties when heated. Then the whole formed by the protective sheet 301 and the tensioning sheet 302 will tightly cover the outside of the carbon fiber layer 1, and then repeat the operation to install another protective component 3 on the outside of the carbon fiber layer 1. Because this protective component 3 has not been processed and is relatively loose, the connection between the protective sheet 301 and the tensioning sheet 302 will not be hindered by the installation of the protective component 3, thereby achieving the effect of protecting the pipe, and the texture of the carbon fiber can also be displayed, and then the inner tube 402 It is inserted into the carbon fiber layer 1 and then comes into contact with the limiting ring 401 to complete the positioning. The filling layer 403 is then sprayed into the cavity formed by the two and then expanded to completely fill the cavity, which can effectively improve the rigidity and strength of the carbon fiber tube, and can absorb and disperse part of the impact force, thereby protecting the tube from damage. The heat insulation layer 404 can play a heat insulation effect to prevent excessive external heat from being transferred to the filling layer 403 and causing damage to it. The positioning column 501 on the outside of a flange 2 is then inserted into the positioning hole 503 of another tube, and then the two flanges 2 are overlapped together. At this time, the through holes of the two flanges 2 will also correspond one to one, which is convenient for the later locking work. Finally, the limiting pin 502 is inserted into the positioning column 501 to complete the preliminary connection.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
