A carbon fiber deflector that is easy to assemble and disassemble

Abstract

This utility model discloses a carbon fiber guide tube that is easy to assemble and disassemble. The advantages are as follows: By installing a quick-assembly assembly between the inner and outer cylinders, when connecting the inner and outer cylinders, the inner cylinder is first inserted into the outer cylinder, and the insert post is inserted into the insertion hole. Then, the screw ring is rotated by a lever. After rotating, the screw ring moves downward along the convex edge on the outer cylinder. As the screw ring moves downward, it presses the conical block into the sliding hole using the conical cavity. Simultaneously, the conical block compresses the spring as it enters the sliding hole, inserting the limiting post into the limiting hole on the insert post. This achieves quick positioning between the inner and outer cylinders. Furthermore, when disassembling the inner and outer cylinders, simply rotating the screw ring upward along the convex edge on the outer cylinder allows the limiting post to separate from the limiting hole as the screw ring moves upward, aided by the spring's reset action. This achieves quick disassembly of the inner and outer cylinders.

Description

Technical Field

[0001] This utility model relates to the field of carbon fiber guide tube technology, specifically to a carbon fiber guide tube that is easy to assemble and disassemble. Background Technology

[0002] Currently, methods for manufacturing monocrystalline silicon include the Czochralski method, the floating zone method, the substrate method, and the sheet-like single crystal growth method. Among these, the Czochralski method is the most widely used. The flow guide tube, as a crucial component of the single crystal furnace, plays a vital role in monocrystalline silicon production. The flow guide tube significantly impacts crystal growth, and the introduction of carbon fiber flow guide tubes into single crystal furnaces represents a significant improvement. Using carbon fiber flow guide tubes improves the flow of argon gas in the upper part of the furnace, accelerating argon flow and greatly reducing silicon oxide deposition on the furnace surface. Furthermore, the temperature protection provided by the carbon fiber flow guide tube reduces heating time, drastically shortening crystallization time and decreasing the incidence of dislocations in the crystal.

[0003] Existing carbon fiber guide tubes typically consist of a conical outer cylinder and an inner cylinder. The inner cylinder is installed inside the conical outer cylinder for transporting materials. There are two main methods for installing the outer and inner cylinders of existing carbon fiber guide tubes: one is to use a snap-fit ​​connection, and the other is to use bolts. The snap-fit ​​connection between the inner and outer cylinders has the disadvantage of being not secure enough and being prone to falling off and separating. On the other hand, the bolt connection between the inner and outer cylinders requires multiple tightening of the bolts, making the disassembly and assembly process between the inner and outer cylinders still cumbersome and inefficient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a carbon fiber guide tube that is easy to assemble and disassemble, which can be quickly inserted between the inner and outer cylinders with a single twisting action, in light of the current state of the technology.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a carbon fiber guide tube that is easy to assemble and disassemble, including an outer cylinder body. The bottom end of the inner cylinder body has a pre-reserved annular hook edge. An inner cylinder body is inserted into the hook edge. A quick-assembly assembly is installed between the outer cylinder body and the inner cylinder body. The quick-assembly assembly includes a lever, a screw ring, a sliding hole, a conical cavity, a conical block, a spring, a limiting post, a limiting hole, an insertion hole, and an insertion post.

[0008] Furthermore, a thermal insulation graphite felt is installed between the outer cylinder and the inner cylinder, and the thermal insulation graphite felt is bonded to the inner wall of the outer cylinder.

[0009] Furthermore, the top of the outer cylinder is also formed with a mounting ring edge on the outside of the self-contained protrusion edge, and the mounting ring edge has a reserved mounting hole.

[0010] Furthermore, there are four insertion posts, which are formed in a ring around the top periphery of the inner cylinder, and the limiting holes are formed on the insertion posts.

[0011] Furthermore, the insertion hole is located on the outer cylinder directly opposite the insertion post, and the sliding hole is provided on one side of the insertion hole on the outer cylinder.

[0012] Furthermore, the limiting post is installed inside the sliding hole, with one end of the limiting post facing the limiting hole and the other end of the limiting post connected to the conical block.

[0013] Furthermore, both the conical block and the limiting post are slidably engaged with the sliding hole, and the spring is installed between the sliding hole and the side wall of the conical block facing the limiting post.

[0014] Furthermore, the screw ring is screwed onto the annular protrusion on the top of the outer cylinder, and there are four levers, which are welded in a ring shape to the outer wall of the screw ring.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention utilizes a quick-connect assembly installed between the inner and outer cylinders. When connecting the inner and outer cylinders, the inner cylinder is first inserted into the outer cylinder, and the insert post is inserted into the insertion hole. Then, a lever is used to rotate the threaded ring. As the threaded ring rotates, it moves downwards along the protruding edge of the outer cylinder. Simultaneously, the conical cavity presses a conical block into the sliding hole. As the conical block enters the sliding hole, a spring is compressed, and a limiting post is inserted into the limiting hole on the insert post. This achieves a quick connection between the inner and outer cylinders. The quick-release mechanism allows for rapid disassembly of the inner and outer cylinders. When disassembling the inner and outer cylinders, simply rotate the screw ring upwards along the raised edge of the outer cylinder. Simultaneously, the spring's resetting action causes the limiting post to separate from the limiting hole, enabling quick disassembly of the inner and outer cylinders. This method achieves disassembly and assembly through a single rotation and screwing operation, avoiding the tedious process of multiple screwing operations, thus increasing the efficiency of disassembly and assembly between the inner and outer cylinders of the carbon fiber guide tube.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] like Figures 1-4 As shown, a carbon fiber guide tube for easy assembly and disassembly in this embodiment includes an outer cylinder 4. An annular hook edge 6 is pre-reserved at the bottom of the inner end of the outer cylinder 4. An inner cylinder 1 is inserted into the hook edge 6. A quick-connect assembly 7 is installed between the outer cylinder 4 and the inner cylinder 1 on the outer periphery of the top. The quick-connect assembly 7 includes a lever 701, a screw ring 702, a sliding hole 703, a conical cavity 704, a conical block 705, a spring 706, a limiting post 707, a limiting hole 708, an insertion hole 709, and an insertion post 710. When connecting the inner cylinder 1 and the outer cylinder 4, the inner cylinder 1 is first inserted into the outer cylinder 4, and the insertion post 710 is inserted into the insertion hole 709. Then, the lever 701 rotates the screw ring 702. After the screw ring 702 rotates, it will move downward along the convex edge on the outer cylinder 4. As the screw ring 702 moves downward, it will press the conical block 705 into the sliding hole 703 with the help of the conical cavity 704. When the conical block 705 enters the sliding hole 703, it will compress the spring 706 and insert the limiting post 707 into the limiting hole 708 on the insert post 710, thereby realizing the quick limiting between the inner cylinder 1 and the outer cylinder 4. At the same time, when disassembling the inner cylinder 1 and the outer cylinder 4, simply rotate the screw ring 702 upward along the convex edge on the outer cylinder 4. As the screw ring 702 moves upward, the limiting post 707 will be separated from the limiting hole 708 by the reset action of the spring 706.

[0026] like Figures 1-4 As shown, in this embodiment, a thermal insulation graphite felt 5 is also installed between the outer cylinder 4 and the inner cylinder 1. The thermal insulation graphite felt 5 is bonded to the inner wall of the outer cylinder 4. The thermal insulation graphite felt 5 can effectively increase the thermal insulation performance of the carbon fiber guide tube. The top of the outer cylinder 4 is also formed with an installation ring edge 3 on the outer side of the self-contained protrusion edge. The installation ring edge 3 has a reserved installation hole 2. The installation hole 2 on the installation ring edge 3 cooperates with the external bolt to realize the reliable installation of the carbon fiber guide tube.

[0027] like Figures 1-4 As shown, in this embodiment, there are four insertion posts 710, which are formed in a ring around the top periphery of the inner cylinder 1. Limiting holes 708 are formed on the insertion posts 710. After the insertion posts 710 and the limiting holes 708 are engaged, a reliable limiting connection can be achieved between the outer cylinder 4 and the inner cylinder 1. Insertion holes 709 are formed on the outer cylinder 4 directly opposite the insertion posts 710. A sliding hole 703 is formed on one side of the insertion hole 709 on the outer cylinder 4. The sliding hole 703 ensures convenient sliding of the conical block 705 and the limiting post 707, while also providing a certain installation space for the spring 706. A limiting post 707 is installed inside the sliding hole 703, with one end of the limiting post 707 facing the limiting hole 708. The other end is connected to a conical block 705, which cooperates with the conical cavity 704 to facilitate the sliding of the conical block 705 within the sliding hole 703. The conical block 705 and the limiting post 707 are both slidably engaged with the sliding hole 703. The spring 706 is installed between the sliding hole 703 and the side wall of the conical block 705 facing the limiting post 707. The spring 706 is mainly used to facilitate the reset of the limiting post 707. The screw ring 702 is screwed onto the annular protrusion on the top of the outer cylinder 4. There are four levers 701, which are welded in a ring shape to the outer wall of the screw ring 702. With the help of the levers 701, the screw ring 702 can be easily rotated and screwed relative to the protrusion on the outer cylinder 4.

[0028] The specific implementation process of this embodiment is as follows: First, with the external bolts and mounting holes 2 in place, the outer cylinder 4 is installed on the corresponding position of the single crystal furnace body. Then, the insulating graphite felt 5 is laid on the outside of the outer cylinder 4, and the inner cylinder 1 is inserted into the outer cylinder 4. Simultaneously, the insert post 710 is inserted into the insertion hole 709. Next, the screw ring 702 is rotated by the lever 701. After rotating, the screw ring 702 moves down along the protruding edge on the outer cylinder 4. As the screw ring 702 moves down, it presses the conical block 705 into the sliding hole 703 using the conical cavity 704. Simultaneously, the conical block 705 compresses the spring 706 as it enters the sliding hole 703, and the limiting post 707 is inserted into the insert post. The limiting hole 708 on 710 enables quick positioning between the inner cylinder 1 and the outer cylinder 4. When disassembling the inner cylinder 1 and the outer cylinder 4, simply rotate the screw ring 702 upward along the convex edge on the outer cylinder 4. As the screw ring 702 moves upward, the spring 706 resets, causing the limiting post 707 to separate from the limiting hole 708, thus achieving quick disassembly of the inner cylinder 1 and the outer cylinder 4. Because this disassembly and assembly method achieves the disassembly and assembly between the inner cylinder 1 and the outer cylinder 4 through a single rotation and screwing operation, it avoids the tedious operation of multiple screwing operations, thereby making the disassembly and assembly efficiency between the inner cylinder 1 and the outer cylinder 4 in the carbon fiber guide tube higher.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
