Description
Technical Field
[0001] This utility model relates to the field of connectors, and more particularly to a connector for connecting wood structures and metal parts. Background Technology
[0002] In the process of connecting wood structures and metal components, specific connectors are needed to achieve a stable and reliable connection between the two in order to meet the requirements of structural strength, functionality and aesthetics in many fields such as architecture, furniture and decoration.
[0003] Traditional methods of connecting wood structures and metal components primarily employ bolting, welding, and simple interlocking. Bolting is a common method, involving drilling holes in both the wood and metal components and then securing them together with bolts and nuts. However, this method has several drawbacks. Firstly, drilling into the wood damages its fiber structure, reducing its strength, especially near the edges or areas subjected to high tensile or shear forces, which can easily lead to cracking and severely compromise the safety and durability of the connection. Secondly, bolting requires precise drilling in both the wood and metal components, demanding high machining accuracy. Even slight deviations in drilling position can result in difficult or unstable connections, increasing construction complexity and cost.
[0004] While welding can achieve strong connections between metal parts and between metal parts and some weldable wood materials (such as specially treated wood composites), the welding process generates high temperatures, which can easily cause heat damage to the wood, leading to carbonization, deformation, and reduced wood performance. Furthermore, welding requires specialized welding equipment and skilled welders, and has stringent requirements for the construction environment and conditions, making it difficult to implement in some on-site construction scenarios. Utility Model Content
[0005] The purpose of this utility model is to provide a connector for wood structures and metal parts, which solves the problems of bolt connection damaging wood, high precision requirements and easy loosening, welding heat damage to wood, and harsh conditions and difficulty in disassembly in traditional connection methods.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A connector for connecting a wooden structure and a metal part includes a connecting piece and a main body piece. The connecting piece is used to fix itself to the wooden structure. A triangular block is provided at the top of the connecting piece. The main body piece is used to connect the metal part. A strip-shaped opening is provided on the surface of the main body piece. A movable piece is symmetrically provided at the top of the main body piece. A toothed groove is provided at equal intervals on one side of each of the two movable pieces. The triangular block cooperates with the toothed groove. A rectangular hole is provided on the surface of the movable piece. A mating hole is provided on the surface of the main body piece at the corresponding position of the rectangular hole. An arc-shaped bending piece is provided inside the rectangular hole. One end of the arc-shaped bending piece is connected to the side wall of the corresponding rectangular hole, and the other end of the arc-shaped bending piece is connected to the side wall of the other side of the corresponding mating hole.
[0007] Preferably, the top of the triangular block is provided with a baffle plate. The presence of the baffle plate can play a certain guiding role during the pushing of the triangular block, ensuring that the triangular block can be pushed more accurately into the space between the movable pieces along the predetermined direction.
[0008] Preferably, small holes are provided at the four corners of the top of the connecting piece, which provide a variety of convenient connection methods for fixing the connecting piece to the wooden structure.
[0009] Preferably, the movable piece has a sliding hole at the top, and the main piece has sliders symmetrically fixedly connected to the top. The sliders are slidably connected inside the corresponding sliding holes. The cooperation between the sliding holes and the sliders provides precise guidance for the movement of the movable piece, ensuring that the movable piece can only move along a specific straight line.
[0010] Preferably, the bottom of the connecting piece has a round hole that extends upward into the interior of the triangular block. When the connecting piece is fixed to the wooden structure, it can be further reinforced by inserting a wooden wedge or a wooden dove into the round hole.
[0011] Preferably, the main body piece is bent downwards on the side away from the triangular block and then extends horizontally to have a fixing part, and the bottom of the fixing part is flush with the bottom of the connecting piece. The fixing part provides a stable and reliable connection structure with the metal part.
[0012] Preferably, the top four corners of the fixing part are provided with waist-shaped holes, which provide a more flexible and reliable connection method.
[0013] Compared with the prior art, the advantages of this utility model are as follows:
[0014] 1. This utility model constructs a multi-layered, high-strength connection system by combining connecting pieces and main pieces with triangular blocks and movable pieces. When connecting wooden structures, the small holes at the four corners of the top of the connecting piece can be initially fixed with the help of bolts or wooden nails, while the round holes at the bottom extending into the inside of the triangular block can be further strengthened with wooden wedges or wooden dowels after inserting them, effectively resisting vertical tensile forces and horizontal shear forces.
[0015] 2. This utility model simplifies the installation process and improves installation efficiency by using a connecting piece and a main body piece in conjunction with a triangular block and a movable piece. During assembly, when the triangular block is pushed between the two movable pieces, the baffle at the top of the triangular block slides along the surface of the movable piece, providing precise guidance. At the same time, the cooperation between the sliding hole at the top of the movable piece and the slider at the top of the main body piece further restricts the movement direction of the movable piece, ensuring that the movable piece can only move along a predetermined straight line, thus avoiding offset and shaking during the installation process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 3 This embodiment provides a connector for connecting a wooden structure and a metal component, including a connecting piece 1 and a main body piece 2. The connecting piece 1 is used to fix itself to the wooden structure. A triangular block 3 is provided on the top of the connecting piece 1. The main body piece 2 is used to connect the metal component. A strip-shaped opening 4 is provided on the surface of the main body piece 2. A movable piece 5 is symmetrically provided on the top of the main body piece 2. A toothed groove 6 is provided at equal intervals on the opposite side of the two movable pieces 5. The triangular block 3 cooperates with the toothed groove 6. A rectangular hole 7 is provided on the surface of the movable piece 5. A mating hole 8 is provided on the surface of the main body piece 2 at the corresponding position of the rectangular hole 7. An arc-shaped bending piece 9 is provided inside the rectangular hole 7. One end of the arc-shaped bending piece 9 is connected to the side wall of the corresponding rectangular hole 7, and the other end of the arc-shaped bending piece 9 is connected to the side wall of the corresponding mating hole 8 on the other side.
[0022] During assembly, the connecting piece 1 is first fixed to the wooden structure using appropriate methods such as bolting or nailing. The main body piece 2 is then assembled to the metal parts using appropriate methods such as welding or bolting. Next, the triangular block 3 is aligned with the strip-shaped opening 4 of the main body piece 2 and the gap between the two movable pieces 5. The triangular block 3 is then pushed in. During the pushing process, the sharp end of the triangular block 3 enters first, and its two inclined surfaces will press against the toothed grooves 6 on the movable pieces 5, causing the two movable pieces 5 to move away from each other under the force, increasing the gap between them. As the movable pieces 5 move, the arc-shaped bending piece 9 connected to the movable pieces 5 undergoes elastic deformation under tension or pressure. When the triangular block 3 is pushed into the designated position, the arc-shaped bending piece 9 will generate a restoring force due to its own elastic properties. This force is used to reset the movable pieces 5. At this time, the two corners of the triangular block 3 are respectively locked in the corresponding toothed grooves 6 of the two movable pieces 5, thereby achieving a stable connection between the connecting piece 1 and the main body piece 2, and thus connecting the wooden structure and the metal parts together.
[0023] The top of the triangular block 3 is provided with a baffle 10. During the process of pushing the triangular block 3 between the two movable pieces 5, the baffle 10 will contact the surface of the movable piece 5. As the triangular block 3 is continuously pushed in, the baffle 10 slides along the surface of the movable piece 5. The presence of the baffle 10 can play a certain guiding role during the pushing of the triangular block 3, ensuring that the triangular block 3 can be pushed into the movable pieces 5 more accurately along the predetermined direction, reducing the deviation during the pushing process. On the other hand, the baffle 10 can also limit the shaking of the triangular block 3 in the direction perpendicular to the surface of the movable piece 5 to a certain extent, enhancing the stability of the connector during the assembly process, and making the connection between the connecting piece 1 and the main body piece 2 more reliable.
[0024] Small holes 11 are provided at the four corners of the top of the connecting piece 1. These holes provide a variety of convenient connection methods for fixing the connecting piece 1 to the wooden structure. In actual assembly, bolts can be passed through the small holes 11 and screwed into the wooden structure to secure the connecting piece 1 to the wooden structure. Alternatively, wooden nails can be passed through the small holes 11 and driven into the wooden structure to fix the connecting piece 1 using the friction and gripping force between the nail and the wood. This multi-hole design increases the flexibility and stability of the connection. Appropriate connection tools and methods can be selected according to the specific material of the wooden structure, the usage scenario, and the required connection strength.
[0025] The top of the movable piece 5 has a sliding hole 12, and the top of the main body piece 2 is symmetrically fixed with sliders 13. The sliders 13 are slidably connected inside the corresponding sliding holes 12. During the assembly of the connector and subsequent use, when the triangular block 3 is pushed between the two movable pieces 5, the inclined surfaces on both sides of the triangular block 3 will press the toothed grooves 6 on the movable pieces 5, causing the two movable pieces 5 to move away from each other. At this time, since the sliders 13 symmetrically fixed to the top of the main body piece 2 are slidably connected inside the corresponding sliding holes 12 on the top of the movable pieces 5, the movement of the movable pieces 5 will be along the direction defined by the sliding holes 12 and the sliders 13. The cooperation of the sliding holes 12 and the sliders 13 is the mechanism for the movable pieces 5 to move. The movement provides precise guidance, ensuring that the movable piece 5 can only move along a specific straight line, avoiding deviation, shaking, or twisting during movement. This guarantees the stability and accuracy of the movable piece 5's movement. This not only facilitates the smooth pushing of the triangular block 3 into the designated position, allowing the two corners of the triangular block 3 to accurately engage in the corresponding toothed grooves 6 of the movable pieces 5 on both sides, achieving a reliable connection between the connecting piece 1 and the main body piece 2, but also, during the use of the connector, when subjected to external forces, the cooperation of the sliding hole 12 and the slider 13 can limit the abnormal movement of the movable piece 5, maintain the overall structural stability of the connector, and improve the service life and safety of the connector.
[0026] The bottom of the connecting piece 1 has a round hole 14, which extends upward into the interior of the triangular block 3. When the connecting piece 1 is fixed to the wooden structure, a wooden wedge or wooden pin can be inserted into the round hole 14. After the wooden wedge or wooden pin is inserted, it forms a whole with the connecting piece 1 and the wooden structure, which increases the stability of the connection and can better withstand forces from different directions, further improving the reliability and safety of the entire wooden structure and metal parts connection.
[0027] The main body piece 2 is bent downwards on the side away from the triangular block 3 and extends horizontally to form a fixing part 15. The bottom of the fixing part 15 is flush with the bottom of the connecting piece 1. When the main body piece 2 is assembled onto the metal part, the fixing part 15 is formed by bending downwards on the side of the main body piece 2 away from the triangular block 3 and extending horizontally. This structure allows the fixing part 15 to fully fit the surface of the metal part. During the connection process, the fixing part 15 can be firmly welded to the metal part by welding. The weld produced by welding can withstand greater tensile and shear forces, ensuring that the main body piece 2 and the metal part will not easily separate. Alternatively, bolts can be passed through the pre-set holes on the fixing part 15 and screwed into the metal part. The reliable connection between the main body piece 2 and the metal part is achieved through the tightening action of the bolts.
[0028] The top four corners of the fixing part 15 are provided with waist-shaped holes 16. When bolt connection is used, since the waist-shaped holes 16 have a certain length margin, even if there is a certain machining error in the position of the corresponding connection hole on the metal part or a slight offset occurs during installation, the bolt can pass through the waist-shaped holes 16 smoothly and be screwed into the metal part. This reduces the requirements for the machining accuracy and installation accuracy of the metal part and improves the installation efficiency.
[0029] 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.
