Description

Technical Field

[0001] This utility model relates to the field of wooden furniture technology, and in particular to a wooden guide rail type drawer structure. Background Technology

[0002] In existing furniture drawer structures, drawer slides, as the core component enabling the drawer to pull out, are mainly divided into two categories: metal slides and wooden slides. While metal slides offer advantages such as high strength and smooth sliding, they also suffer from higher material costs, stricter installation precision requirements, and poor coordination with the overall style of wooden furniture. Furthermore, metal components are prone to corrosion over long-term use, affecting their lifespan. Additionally, the friction between metal parts during the pulling process can generate noise, making it difficult to meet the need for quiet use. Wooden slides, on the other hand, maintain the unity and natural beauty of the overall design because they are made of the same material as the furniture itself. They are also lower in cost and more environmentally friendly, making them widely used in Chinese-style furniture and furniture that emphasizes a natural texture.

[0003] However, traditional wooden drawer slides suffer from excessive friction, leading to jamming and a relatively short lifespan for the drawers. Utility Model Content

[0004] The main purpose of this utility model is to provide a wooden guide rail drawer structure that can effectively solve the problems of wooden guide rails getting stuck due to excessive friction and the relatively short service life of the drawer.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wooden drawer slide structure, including drawer side panels; Wooden guide rails are fixed to the inner walls of the left and right sides of the drawer side panel; Limiting block one is fixed to the upper front side of the wooden guide rail; The drawer body is slidably mounted inside wooden guide rails; Grooves are formed on both sides of the drawer body and cooperate with the wooden guide rails; Limiting block two is disposed on the inner wall of the groove and cooperates with limiting block one; The wooden guide rail is impregnated with paraffin wax.

[0006] Preferably, the limiting block has a parallelogram structure.

[0007] Preferably, the interior of the first limiting block and the second limiting block are also impregnated with paraffin wax.

[0008] Preferably, the upper left corner of the first limiting block and the lower right corner of the second limiting block are both provided with guide bevels.

[0009] Preferably, the wooden guide rail is fixed to the inner wall of the drawer side panel by a combination of countersunk wood screws and wood glue.

[0010] Preferably, the head of the countersunk wood screw is fully embedded inside the wooden guide rail and does not protrude from the outer surface of the wooden guide rail.

[0011] Preferably, the drawer side panel, wooden guide rail, and drawer body are all made of solid wood, and the direction of the wood fibers of the solid wood is consistent with the length direction of the wooden guide rail.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model employs a paraffin impregnation process on the wooden guide rails. Liquid paraffin fully fills the pores of the wood, forming an internal lubricating layer after cooling and solidification. During the drawer's operation, the friction and heat generated by the wood cause the paraffin in the pores to slowly melt, forming a continuous and uniform lubricating film on the contact surface between the wooden guide rail and the groove. This significantly reduces the sliding friction resistance between the two, achieving a smooth drawer feel and effectively reducing the jamming problem caused by excessive friction in traditional wooden guide rails. Simultaneously, the lubricating film also reduces direct wear between the wood grains, slows down the deformation rate of the wooden guide rail and groove, and significantly extends the overall lifespan of the drawer structure.

[0013] 2. This utility model's structure, through the coordinated design of limiting block one and limiting block two, and the guide beveled surface structure at their contact ends, allows users to easily move limiting block two past limiting block one along the beveled surface by simply lifting the drawer body slightly upwards without the need for additional tools, thus completing the quick assembly and disassembly of the drawer. This design not only ensures the stability of the limiting position during normal use but also provides convenience for subsequent internal cleaning of the drawer and maintenance of the guide rails, solving the common contradictions of "unreliable limiting position" or "difficult assembly and disassembly" in traditional wooden drawer slides.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-3As shown, a wooden guide rail drawer structure includes a drawer side panel 1, with wooden guide rails 2 fixed to both the left and right inner walls of the drawer side panel 1. The wooden guide rails 2 are fixed to the side of the drawer side panel 1 by wood screws, and the wood screws need to be countersunk to prevent the protruding heads from affecting the normal pulling out of the drawer body 4. A limit block 3 is provided at the upper end of the wooden guide rail 2. The drawer body 4 also slides inside the drawer side panel 1. The drawer body 4 also has grooves 5 on both sides that cooperate with the wooden guide rails 2. The wooden guide rails 2 cooperate with the grooves 5 to facilitate the pulling out of the drawer body 4. The inner wall of the grooves 5 is also provided with a limit block 6 that cooperates with the limit block 3. The mutual cooperation between the limit block 3 and the limit block 6 is used to limit the sliding stroke of the drawer body 4 and prevent the drawer from disengaging from the rails when fully pulled out.

[0018] In addition, to reduce friction when the drawer body 4 is pulled out, the wooden guide rail 2 is impregnated with paraffin wax. During processing, the paraffin wax is heated and melts into a liquid state. The wooden guide rail 2 is then placed in the liquid paraffin wax, which slowly seeps into the wooden guide rail 2 and fills the pores inside. When the drawer body 4 is pulled out, the side of the groove 5 comes into contact with the wooden guide rail 2. The wood heats up when it rubs against the wood, and the solid paraffin wax on the outside gradually melts and adheres to the side wall of the groove 5. A lubricating layer is formed on the surface of the side wall of the groove 5 to reduce the friction between the groove 5 and the wooden guide rail 2, making the drawer body 4 smoother when pulled out.

[0019] like Figure 2 and Figure 3 As shown, the limiting blocks are parallelogram structures. The upper left corner of limiting block 3 and the lower right corner of limiting block 6 are both provided with guide bevels. When it is necessary to completely remove the drawer body 4 from the drawer side panel 1, by slightly lifting the drawer body 4 along the direction of the guide bevels, limiting block 6 can smoothly pass over the drawer side panel 1 with the help of the bevels, so that the drawer body 4 is separated from the wooden guide rail 2. During daily pulling, the non-beveled parts of the two limiting blocks can still restrict the sliding stroke of the drawer body 4 to prevent the drawer body 4 from falling out. This beveled structure not only ensures the limiting stability in normal use, but also provides convenient guidance for the complete disassembly and assembly of the drawer. The drawer can be easily taken out and put back without additional tools, which is convenient for later cleaning or maintenance.

[0020] In addition, the interiors of limit block 3 and limit block 6 are also impregnated with paraffin wax. Since the top surface of the groove 5 of the drawer body 4 contacts the top surface of limit block 3 when the drawer body 4 is pulled out, and the bottom surface of limit block 6 contacts the top surface of the wooden guide rail 2, the limit blocks impregnated with paraffin wax can make the drawer body 4 pull out more smoothly.

[0021] Furthermore, the drawer side panel 1, the wooden guide rail 2, and the drawer body 4 are all made of solid wood, and the direction of the wood fibers of the solid wood is consistent with the length direction of the wooden guide rail 2. This can effectively avoid the problem of deformation, cracking, or excessive local wear of the wooden guide rail 2 due to long-term stress, while reducing the risk of deformation of the drawer side panel 1 due to support stress, and greatly extending the service life of the overall drawer structure.

[0022] The specific implementation method of this embodiment is as follows: 1. Paraffin impregnation of wooden guide rail 2 Solid paraffin wax is heated until it melts, and the wooden guide rail 2 is completely immersed in the liquid paraffin wax for a period of time. After being removed, it is allowed to cool naturally to room temperature, allowing the paraffin wax to fill the pores of the wood and form an internal lubricating layer.

[0023] II. Assembly Process 1. Wooden guide rail 2 fixed Positioning and pretreatment: Draw installation lines on the drawer side panel 1 relative to the inner wall according to the dimensions of the wooden guide rail 2, ensuring that the height of the installation lines on both sides is consistent; apply wood glue evenly to the back of the wooden guide rail 2; Fixing procedure: Attach the wooden guide rail 2 to the installation line and fix it with countersunk wood screws, ensuring that the screw heads are fully embedded in the wooden guide rail 2 to avoid protruding and affecting the pulling; after the white glue has completely cured, the installation of the wooden guide rail 2 is complete.

[0024] 2. Assembly and Verification of Drawer Body 4 Assembly operation: Align the grooves 5 on both sides of the drawer body 4 with the wooden guide rail 2 and slowly push it in. (During the pushing process, the drawer body 4 needs to be lifted upwards to prevent the two limit blocks from hitting each other, thus affecting the normal insertion of the drawer body 4.) Functional verification: Pull the drawer outward to verify the limiting effect and ensure smooth and unobstructed pulling; lift the drawer upward to verify the effect of the guide bevel, ensuring that the drawer can smoothly pass the limiting block for disassembly and reassembly. At the same time, the operator needs to pull the drawer body 4 outward repeatedly to ensure that a continuous lubricating film is formed on the contact surface between the wooden guide rail 2 and the groove 5, reducing the frictional resistance during sliding.

[0025] It should be noted that the specific installation methods of the drawer side panel 1, the wooden guide rail 2, and the drawer body 4 in this utility model are all conventional designs, and will not be described in detail in this utility model.
