Description

Technical Field

[0001] This utility model relates to the field of carbon fiber load-bearing bar technology, specifically a carbon fiber composite load-bearing bar. Background Technology

[0002] Carbon fiber composite load-bearing bars are high-performance structural components with carbon fiber composite materials as their core. Through fiber winding technology and pre-embedded pipe joint design, they achieve a perfect combination of lightweight and high strength, and are widely used in construction, aerospace, sports and other fields.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] When existing carbon fiber support rods are used for load-bearing support, different numbers of support rods are connected according to the distance between two support points. However, if there is a small gap difference between the support rod and the support point, the current connection rods do not have a fine-tuning mechanism, which makes the support of the support rods insufficient. The traditional method of determining the length of the support rod according to the distance between two points is time-consuming and labor-intensive, reducing work efficiency.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a carbon fiber composite support rod, which solves the problem that traditional carbon fiber support rods lack a fine-tuning mechanism when there are small gaps, and that customizing a carbon fiber support rod of a specified length is time-consuming and labor-intensive, thus reducing work efficiency. At the same time, it improves the support stability of the carbon fiber support rod body.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A carbon fiber composite support rod includes a carbon fiber support rod body with a contraction cavity inside. A fine-tuning bearing extending outward is rotatably mounted on the top of the carbon fiber support rod body. A lead screw connected to the fine-tuning bearing via a thread is movably mounted inside the contraction cavity. A hexagonal shank is fixedly mounted on the top of the fine-tuning bearing. A positioning bolt extending into the contraction cavity is rotatably mounted inside a threaded hole at the top front end of the carbon fiber support rod body.

[0009] Preferably, a bottom support plate is movably provided at the bottom of the carbon fiber load-bearing rod body, and a top support plate is movably provided at the top of the carbon fiber load-bearing rod body.

[0010] Preferably, a first connecting block is fixedly installed on the top of the shrinkage cavity, a first threaded block is fixedly installed inside the first connecting block, and the first threaded block is threadedly connected to a screw hole inside the top support plate.

[0011] Preferably, a second threaded block is fixedly installed at the bottom of the carbon fiber support rod body, and the second threaded block is threadedly connected to a screw hole inside the bottom support plate.

[0012] Preferably, the inner wall of the carbon fiber support rod body is fixedly provided with a honeycomb layer, and the rear end of the positioning bolt is made of rubber.

[0013] Preferably, a rubber pad is fixedly installed at the ends of the bottom support plate and the top support plate that are far apart from each other, and the surface of the rubber pad is evenly distributed with anti-slip texture.

[0014] Compared with the prior art, this utility model provides a carbon fiber composite support rod with the following beneficial effects: When the carbon fiber support rod body provides load-bearing support, if there is a gap between two points due to insufficient length of the carbon fiber support rod body, the hexagonal handle is rotated to move the lead screw upward inside the contraction cavity, thereby filling the small gap between the two support points with the extended length of the lead screw. Then, by rotating the positioning bolt through the screw hole of the carbon fiber support rod body to the inside of the contraction cavity, the rubber head at one end of the positioning bolt contacts the lead screw, thereby limiting and fixing the lead screw. At this time, the carbon fiber support rod body can firmly provide seamless support between the two points, avoiding the situation where traditional carbon fiber support rod bodies lack a fine-tuning mechanism when there is a small gap, and it is time-consuming and laborious to customize a carbon fiber support rod body of a specified length, thus reducing work efficiency. At the same time, the support stability of the carbon fiber support rod body is improved. Attached Figure Description

[0021] 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.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a carbon fiber composite load-bearing bar.

[0023] Please see Figures 1-5 A carbon fiber composite support rod includes a carbon fiber support rod body 1. A contraction cavity 101 is formed inside the carbon fiber support rod body 1. A fine-tuning bearing 102 extending to the outside is rotatably installed at the top inside the carbon fiber support rod body 1. A lead screw 103 connected to the fine-tuning bearing 102 by threads is movably installed inside the contraction cavity 101. A hexagonal swivel 104 is fixedly installed at the top of the fine-tuning bearing 102. A positioning bolt 105 extending into the contraction cavity 101 is rotatably installed inside the threaded hole at the top front end of the carbon fiber support rod body 1. The rear end of the positioning bolt 105 is made of rubber.

[0024] With the above structural setup, when the carbon fiber composite support rod needs to provide load-bearing support, the carbon fiber support rod body 1 is first placed vertically between two support points. Then, the hexagonal handle 104 is rotated according to the gap between the top of the carbon fiber support rod body 1 and the support points. Since the lead screw 103 is connected to the fine-tuning bearing 102 by threads, the fine-tuning bearing 102 drives the lead screw 103 to rise, thus completely filling the gap at the top of the carbon fiber support rod body 1. Then, the positioning bolt 105 is rotated and installed in the screw hole at the front end of the carbon fiber support rod body 1, extending into the interior of the contraction cavity 101. At this time, the rubber head at the rear end of the positioning bolt 105 contacts the lead screw 103, increasing the friction force, thereby fixing the lead screw 103 to a suitable length, so that the carbon fiber support rod body 1 is firmly supported between the two points. This solves the problem that when there is a small gap in the traditional carbon fiber support rod body 1 support, the lack of a fine-tuning mechanism and the time-consuming and laborious process of customizing a carbon fiber support rod body 1 of a specified length reduces work efficiency. At the same time, it improves the support stability of the carbon fiber support rod body 1.

[0025] Furthermore, a bottom support plate 2 is movably installed at the bottom of the carbon fiber support rod body 1, and a top support plate 3 is movably installed at the top of the carbon fiber support rod body 1. A rubber pad 4 is fixedly installed at the ends of the bottom support plate 2 and the top support plate 3 that are far apart from each other. The surface of the rubber pad 4 is evenly distributed with anti-slip textures, and a honeycomb layer 109 is fixedly installed on the inner wall of the carbon fiber support rod body 1. When the carbon fiber support rod body 1 is supported between two points, the bottom support plate 2 and the top support plate 3 are in contact with the surfaces of the support points. The anti-slip textures on the surface of the rubber pad 4 increase the friction of the contact surface, making the carbon fiber support rod body 1 more firmly supported. Since the internal shrinkage cavity 101 of the carbon fiber support rod body 1 is hollow, the honeycomb layer 109 installed on the inner wall of the carbon fiber support rod body 1 improves the impact resistance of the carbon fiber support rod body 1, thereby improving the firmness of the carbon fiber support rod body 1.

[0026] Furthermore, a first connecting block 106 is fixedly installed on the top of the contraction cavity 101, and a first threaded block 107 is fixedly installed inside the first connecting block 106. The first threaded block 107 is threadedly connected to a threaded hole inside the top support plate 3. Specifically, by rotating the bottom end of the top support plate 3 onto the top of the first connecting block 106, the first threaded block 107 extends threadedly into the threaded hole inside the top support plate 3, thereby fixing the top support plate 3 to the top of the contraction cavity 101 for support, while also facilitating the installation and removal of the top support plate 3 by workers.

[0027] Furthermore, a second threaded block 108 is fixedly installed at the bottom of the carbon fiber support rod body 1. The second threaded block 108 is threaded through and connected to a screw hole inside the bottom support plate 2. The second threaded block 108 is rotatably installed in the screw hole inside the bottom support plate 2, thereby fixing the bottom support plate 2 to the bottom end of the carbon fiber support rod body 1 for support, while also facilitating the disassembly and reassembly of the bottom support plate 2 by workers.

[0028] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
