Description

Technical Field

[0001] This utility model belongs to the field of composite material and metal material connection technology, and particularly relates to a connection structure for composite material and metal material. Background Technology

[0002] Carbon fiber composites are widely used in the aerospace field due to their good strength, high modulus, light weight, high temperature resistance and good formability. Due to the requirements of overall structural performance and function, composite laminate structures and metal components need to be mechanically connected to form a whole.

[0003] However, existing technologies have some problems: the current mechanical connection methods for composite materials and metals include rivets, bolts and screws. For the connection of thick plates under heavy loads, bolts are used. When the bolt head cannot protrude from the surface of the composite structure, countersunk bolts can only be used. Countersunk bolts reduce the pressing area between the bolt and the hole of the composite material and cause local stress concentration, which can easily lead to fiber breakage, delamination, and even loss of excellent mechanical properties. This affects the mechanical properties of ring connections or barrel-shaped structure connections and has certain limitations. Therefore, we propose a connection structure for composite materials and metal materials. Utility Model Content

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] like Figures 1 to 3 As shown in the figure, the present invention provides a connection structure for composite materials and metal materials, comprising: a connection component 1, which includes a reinforcing sleeve 101, a first connecting sleeve 102, and a second connecting sleeve 103. The first connecting sleeve 102 and the second connecting sleeve 103 are slidably installed inside the reinforcing sleeve 101. Pin holes are provided on both sides of the reinforcing sleeve 101, and a first pin 3 is provided inside the pin hole. The first pin 3 is correspondingly arranged with the first connecting sleeve 102 and the second connecting sleeve 103.

For example, it can be used to assemble the connection component 1 with other structures, or to connect the ear plates 2 with materials, which can improve the strength of the materials and thus improve the applicability.

[0023] Specifically, such as Figures 1 to 3 As shown, in use, the composite material tube is fixed inside the first connecting sleeve 102, and the metal tube is fixed inside the second connecting sleeve 103. Then, the first connecting sleeve 102 and the second connecting sleeve 103 are retracted into the reinforcing sleeve 101. The first pins 3 are inserted from both sides of the reinforcing sleeve 101 to fix the first connecting sleeve 102 and the second connecting sleeve 103. Then, the ear plate 2 is fixed to the material surface with screws to improve the connection strength between different materials, thereby achieving the effect of convenient use. The structure is simple, which improves the yield, quality, precision and efficiency, thus increasing the service life. It also saves energy consumption, raw materials and processes, effectively reducing product costs. At the same time, it is easier to process, operate, control and use.

[0024] It should be noted that the diameter of the first pin 3 is 0.05-0.1 mm larger than the diameter of the hole. The first pin 3 is sealed by liquid nitrogen cooling for fixation. The low temperature characteristics of liquid nitrogen enable it to quickly reduce the temperature of the sealing pin and its surrounding environment, thereby improving the surface quality, reducing material surface defects caused by high temperature, and improving the sealing performance of the sealing pin.

[0025] Furthermore, the first connecting sleeve 102 includes a first movable sleeve 1021, a connecting groove 1022 is provided on one side of the first movable sleeve 1021, and connecting blocks 104 are provided at the upper and lower ends of the inner wall of the reinforcing sleeve 101, and the connecting blocks 104 are slidably connected to the connecting groove 1022.

[0026] Specifically, such as Figure 2 As shown, through the cooperation of the connecting block 104 and the connecting groove 1022, the first movable sleeve 1021 can extend and retract at the upper part of the inner wall of the reinforcing sleeve 101, thereby facilitating the installation of composite material pipes or metal pipes and improving the ease of installation.

[0027] Furthermore, an opening 1023 is provided on the inner wall of the connecting groove 1022, and a second pin 1025 is provided in the opening 1023, which is engaged with the opening 1023.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, after the material is placed inside the first movable sleeve 1021, the second pin 1025 is inserted. The second pin 1025 is sealed by liquid nitrogen cooling to improve the sealing effect.

[0029] Furthermore, the second connecting sleeve 103 includes a second movable sleeve 1031, and a movable groove 1032 is provided on one side of the second movable sleeve 1031. The movable groove 1032 is movably connected to the connecting block 104.

[0030] Specifically, such as Figures 1 to 3 As shown, through the cooperation of the connecting block 104 and the movable groove 1032, the second movable sleeve 1031 can extend and retract at the lower end of the inner wall of the reinforcing sleeve 101, thereby facilitating the installation of composite material pipes or metal pipes and improving the ease of installation.

[0031] Furthermore, the inner wall of the movable groove 1032 is provided with a through hole, and a third pin 1033 is provided inside the through hole, which is engaged with the through hole.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, after the material is placed inside the second movable sleeve 1031, the third pin 1033 is inserted. Similarly, the third pin 1033 is sealed by liquid nitrogen cooling, which improves the sealing effect and firmness.

[0033] Furthermore, a retaining plate 1024 is provided at one end of the first movable sleeve 1021, and a retaining groove 1034 is provided at one end of the second movable sleeve 1031. The retaining plate 1024 is engaged with the retaining groove 1034. A slot is provided on one side of both the retaining plate 1024 and the retaining groove 1034, and the slot is correspondingly provided with the first pin 3.

[0034] Specifically, such as Figures 1 to 3 As shown, the first movable sleeve 1021 and the second movable sleeve 1031 each occupy half of the interior of the reinforcing sleeve 101. After the first movable sleeve 1021 and the second movable sleeve 1031 complete the installation of the material, they are reset. At this time, the clamping plate 1024 will be clamped in the clamping groove 1034. The slot on one side of the clamping plate 1024 and the clamping groove 1034 coincides with the pin hole on one side of the reinforcing sleeve 101. Then, the first pin 3 is inserted to fix the whole structure, thereby increasing the stress structure and extending the service life.

[0035] 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.
