Abstract
Description
Technical Field
[0001] The utility model belongs to the furniture industry, and particularly relates to a hidden three-dimensional wooden frame mortise and tenon joint reinforcement device. Background Art
[0002] The mortise and tenon structure is a traditional building structure, and its main function is to connect the components tightly to form a stable building system. The characteristic of the mortise and tenon structure is that the components are connected by the tenon and the mortise. The tenon is a protruding part, and the mortise is a recessed part. The two components are connected together using precision processing methods to prevent the components from displacement and falling off. Several different mortise and tenon structures are combined together to form wooden buildings, wooden machinery, and wooden furniture. Affected by processing technology, tools, and processes, the mortise and tenon connection cannot be very tight, and there will be a certain gap between the mortise and tenon. When the mortise and tenon structure is subjected to force, relative displacement will occur between the mortise and tenon, resulting in loosening of the mortise and tenon joints. To solve this problem, the mortise and tenon joints must be reinforced. At present, there are about five existing reinforcement technologies for the mortise and tenon joints of wooden frames, which are: ① Wooden wedge reinforcement technology. The so-called wooden wedge reinforcement technology is to drive a wooden wedge into the gap at the mortise and tenon connection node, increase the friction between them by increasing the pressure between the mortise and tenon, and achieve the purpose of preventing the mortise and tenon structure from loosening. Sometimes, in order to prevent the wooden wedge from loosening, glue is applied on the surface of the wooden wedge; ② Wooden pin reinforcement technology. The so-called wooden pin reinforcement technology is to drill a hole at the appropriate position of the tenon and mortise. When the tenon and mortise are connected, the two holes overlap, and the wooden pin is inserted into the two holes to make the tenon and mortise tightly connected together. Sometimes, in order to prevent the wooden pin from loosening, glue is applied on the surface of the wooden pin; ③ Glue bonding reinforcement technology. The so-called glue bonding reinforcement technology is to fill the gap between the tenon and mortise with glue, and use the bonding method to make the tenon and mortise tightly connected together; ④ Self-locking mechanism reinforcement technology. The so-called self-locking mechanism reinforcement technology is to combine multiple tenons and mortise together, use the interaction between them, limit the displacement of each component, form a self-locking mechanism, and make the tenon and mortise tightly connected together. ⑤ Metal component reinforcement technology. The so-called metal component reinforcement technology is to use fasteners to fix metal components on the tenon and mortise components respectively, so that the tenon and mortise are tightly connected together. The above five processing technologies for wood frame nodes all have some shortcomings to varying degrees. Taking solid wood mortise and tenon furniture as an example, the shortcomings are: ① For furniture with solid wood mortise and tenon structure made by wooden wedges, wooden pins, and self-locking mechanism reinforcement technology, it is very difficult to disassemble and replace parts during maintenance, which can easily cause damage to the mortise and tenon components and increase the maintenance cost; ② For furniture made by glue bonding reinforcement technology, when a component of the furniture is damaged, it is impossible to disassemble the component for replacement and repair, resulting in the scrapping of the entire furniture, causing certain economic losses to consumers and causing serious waste of wood resources.At the same time, a large amount of domestic garbage is also generated, causing environmental pollution; ③ There are a large number of harmful substances in the glue, which spread to people's living environment and have some adverse effects on people's health; ④ Furniture made by glue bonding reinforcement technology cannot be disassembled and assembled repeatedly, so the storage and transportation of furniture have to be stored and transported as a whole. This method occupies a large space and increases the cost of storage and transportation; ⑤ The wooden wedge and wooden pin reinforcement technology is adopted. The size of the wooden wedge and wooden pin depends on the experience of the craftsman. The wooden wedge and wooden pin are too small, and the mortise and tenon structure is not reinforced firmly; the wooden wedge and wooden pin are too large, which is easy to damage the mortise and tenon components; ⑥ The wooden pin and self-locking mechanism reinforcement technology are adopted. These two processing technologies have complex structures, high process and precision requirements, high processing difficulty, and long working hours. As a result, the production efficiency is too low, the production cost is too high, and the economic benefits are poor. It is not suitable for large-scale production of digitalization and machining. It is only suitable for small-scale production in manual workshops. Secondly, there are very few craftsmen who can make wooden pins and self-locking mechanism reinforcement technology, which makes it difficult to promote and use these two reinforcement technologies on a large scale; ⑦ Furniture made with glue bonding reinforcement technology cannot be disassembled due to the mortise and tenon structure, resulting in the inability to reuse the parts of waste furniture, and the recycling of wood resources has also increased the difficulty. This has led to a huge waste of wood resources and made it impossible to achieve green development in the furniture industry. Summary of the invention
[0003] The purpose of the utility model is to overcome the above technical deficiencies and provide a hidden three-dimensional wood frame mortise and tenon joint reinforcement device which is easy to disassemble and assemble, can be disassembled and assembled repeatedly, is convenient for repair and replacement of parts when furniture is damaged, and has a good reinforcement effect.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a hidden three-dimensional wood frame mortise and tenon node reinforcement device includes a mortise component and a mortise component, and is characterized in that a mortise component groove is provided on the mortise component, a bracket is placed in the mortise component groove, and the bracket and the mortise component are connected by a fastener 1; a mortise component groove 1 is provided on the mortise component 1, a wing plate 1 is placed in the mortise component groove 1, and the wing plate 1 and the mortise component 1 are connected by a fastener 3; a mortise component groove 2 is provided on the mortise component 2, a wing plate 2 is placed in the mortise component groove 2, and the wing plate 2 and the mortise component 2 are connected by a fastener 2; the bracket and the wing plate 1 and the wing plate 2 are connected as a whole.

[0008] The following is a specific description with reference to the accompanying drawings:
[0009] For example, see the attached Figure 1, first connect the three-dimensional mortise and tenon structure, and then install the hidden three-dimensional wood frame mortise and tenon node reinforcement device on the inner side of the three-dimensional mortise and tenon structure. The hidden three-dimensional wood frame mortise and tenon node reinforcement device is provided with a mortise component groove 4-1 on the mortise component 4, a metal bracket 1 is placed in the mortise component groove 4-1, two bolt holes are drilled on the two sides of the metal bracket 1, and the metal bracket 1 and the mortise component 4 are connected by a flat head bolt, i.e., a fastener 7; a mortise component groove 15-1 is provided on the tenon component 15, a metal wing plate 12 is placed in the tenon component groove 15-1, two bolt holes are drilled on the metal wing plate 12, and the metal wing plate 12 and the tenon component 15 are connected by a fastener 39; a mortise component groove 26-1 is provided on the tenon component 26, a metal wing plate 23 is placed in the tenon component groove 26-1, two bolt holes are drilled on the metal wing plate 23, and the metal wing plate 23 and the tenon component 26 are connected by a fastener 23. The fasteners shall be anti-loosening flat head bolts, and the material thereof shall be corrosion-resistant and strong. The metal bracket 1, the metal wing plate 1 2 and the metal wing plate 2 3 shall be made of corrosion-resistant and strong metal materials.
[0010] The working principle of the utility model is divided into three aspects: connection force, friction force and clamping force. First of all, the connection force is the force formed by the tenon and the mortise when connected, which makes the three components tightly combined to form a rigid connection. The size of this connection force depends on the shape and processing accuracy of the tenon and the mortise, as well as the insertion depth during connection. If the shape and processing accuracy of the tenon and the mortise are better, the deeper the insertion depth, the greater the connection force will be. Secondly, the friction force and the close fit of the tenon and mortise structure form an important friction force between the two components. This force can strengthen the connection and make it more stable. The size of the friction force depends on the surface roughness, material, temperature and weight between the two components. The size of the friction force is essentially impossible to measure directly, but it is one of the important factors that the tenon and mortise structure can withstand external loads. Finally, the clamping force. When the three components are connected together, if they are not tightly fitted, gaps will appear. In order to eliminate these gaps, technologies such as clamping wedges and glue bonding can be used to make the tenon and mortise tightly combined. The connection force, friction force and clamping force of the tenon and mortise structure, no matter which method is used, as long as any of the three forces is increased, the firmness of the tenon and mortise structure will be increased. The utility model adopts a method of increasing the connection force: that is, the hidden three-dimensional wood frame mortise and tenon node reinforcement device is a mutually perpendicular three-dimensional integrated structure. After the mortise structure 4, the tenon component 1 5, and the tenon component 2 6 are connected and fixed, the connection force between the three structures is increased, thereby hindering the displacement of the mortise structure 4, the tenon component 1 5, and the tenon component 2 6 relative to the device in all directions, playing a role in preventing the mortise and tenon structure from loosening and reinforcing the mortise and tenon structure. Since the device is movably connected by fasteners and mortise and tenon joints, it is convenient to disassemble and can be repeatedly disassembled and assembled, which is convenient for furniture maintenance and prolongs the service life.
