Description

Technical Field

[0001] This utility model relates to the field of bamboo and wood clamping and fixing technology, specifically to a bamboo and wood fixing device. Background Technology

[0002] Bamboo and wood is a comprehensive term encompassing both bamboo and wood resources. Both are renewable materials found in nature and share many similarities in processing techniques and applications. Therefore, they are often collectively referred to as bamboo and wood, such as in bamboo and wood boards and bamboo and wood chopsticks. In terms of characteristics, both bamboo and wood possess unique textures and excellent plasticity, making them important raw materials for furniture and building materials. Specifically, bamboo and wood can be processed into furniture frames, such as sturdy and durable tables, chairs, and wardrobes. Their excellent strength and stability effectively support the weight of the furniture, ensuring safe use. Furthermore, bamboo and wood can be processed through peeling, gluing, and hot pressing to produce industrial bamboo and wood boards, which are then transformed into various decorative panels for widespread use in furniture surface decoration, creating diverse home atmospheres and styles to meet people's pursuit of a better life.

[0003] In bamboo and wood processing, to ensure stability during cutting, grinding, and other operations, the bamboo and wood must first be secured. This is done using tools such as bench vises and workbench clamps to firmly clamp the bamboo and wood, ensuring they do not shift during processing and thus guaranteeing accuracy and safety. Subsequently, cutting and grinding machines are used to cut and grind the bamboo and wood to achieve the desired processing requirements. For clamps with a ring structure, the bamboo and wood must be inserted into the ring's inner cavity from one side, and then the clamp is adjusted to hold and secure the bamboo and wood. However, due to the slender structure of bamboo and wood, inserting it into the ring clamp is particularly cumbersome. In contrast, using a bench vise with one open side is more convenient and efficient for holding bamboo and wood; simply placing the bamboo and wood within the vise's clamping area is sufficient to hold and secure it. However, to prevent bamboo and wood from accidentally slipping out of the vise's opening during clamping, the bamboo and wood must be firmly gripped by hand. This not only increases the difficulty of clamping but also poses a safety risk of hand injury. Therefore, there are still shortcomings in the bamboo and wood clamping and fixing methods, and the bamboo and wood fixing device needs to be improved to make the clamping operation simple and safe, prevent the bamboo and wood from slipping out, and improve the efficiency and safety of bamboo and wood processing.

[0008] Preferably, the locking groove is located at the end of the top plate of the fixed frame away from the side plate of the fixed frame, and one side of the vertical block of the fixed block protrudes from one end of the locking groove.

[0009] Preferably, two support plates are provided below the fixed frame, and the top ends of the two support plates are respectively installed on both sides of the bottom plate of the fixed frame.

[0012] The beneficial effects of this utility model are as follows: First, this utility model creates a clamping area for bamboo and wood through a fixed frame with an opening on one side, allowing the bamboo and wood to be placed within this clamping area. A fixed plate hinged to the bottom plate of the fixed frame allows the fixed plate to rotate around the bottom plate. A spring and a fixing block on the top plate of the fixed frame constrain the top of the fixed plate, thereby closing the opening of the fixed frame and preventing the bamboo and wood from sliding out. Furthermore, the guide groove on the fixing block guides the top of the fixed plate for constraint, quickly closing the opening of the fixed frame and simplifying the clamping operation. Finally, a threaded pressure rod on the fixed plate allows for adjustment of the rod's extension and retraction, thus pressing and fixing the bamboo and wood placed within the fixed frame to the side wall of the frame to meet the clamping requirements.

[0013] Secondly, this invention utilizes a pressure plate to press the bamboo or wood placed within the clamping area of ​​the fixed frame against the side plate of the fixed frame. A cylinder, disc, and cover allow the pressure rod and pressure plate to be rotatably connected. A fixing rod prevents the pressure plate from rotating relative to the fixed plate, ensuring that the pressure plate does not rotate when the pressure rod is turned. This allows the pressure plate to move towards or away from the side plate of the fixed frame, thus pressing the bamboo or wood placed within the clamping area of ​​the fixed frame. Furthermore, a handle allows the pressure rod to be turned, and a fixing sleeve reinforces the threaded connection between the fixed plate and the pressure plate, improving the connection effect between the fixed plate and the pressure rod.

[0014] Furthermore, this invention features a locking groove at the end of the top plate of the fixed frame, allowing one side of the vertical block of the fixed block to protrude from one end of the locking groove. This enables the vertical block to rotate by pushing or pulling, quickly releasing the locking of the fixed block onto the fixed plate, thus releasing the clamping and fixing of the bamboo or wood placed within the clamping area of ​​the fixed frame. Moreover, the invention utilizes a support plate and roller shaft to move the fixed frame along the extension direction of the support block, adjusting the position of the clamped bamboo or wood to meet processing needs. Limiting rods and nuts on the fixed frame secure it to the support base, allowing switching between moving and fixed states. Guide rails and sliders constrain the movement of the fixed frame, reducing swaying and improving stability. Attached Figure Description

[0021] like Figures 1 to 5As shown, a bamboo and wood fixing device includes a fixing frame 1 with an opening on one side. The fixing frame 1 includes a top plate, a side plate, and a bottom plate. The upper and lower ends of the side plate are respectively connected to one end of the top plate and one end of the bottom plate of the fixing frame 1. A fixing plate 2 is provided on the open end of the fixing frame 1. The bottom end of the fixing plate 2 is hinged to the bottom plate of the fixing frame 1. A hinge groove is provided at the bottom of the fixing plate 2, and the hinge groove is fitted onto the other end of the bottom plate of the fixing frame 1. A first hinge rod is provided on the bottom plate of the fixing frame 1, and the first hinge rod is installed on the other end of the bottom plate of the fixing frame 1. A first hinge hole is provided at the bottom of the fixing plate 2, and the first hinge hole is movably fitted onto the bottom plate. The first hinge rod is mounted on the first hinge rod, the diameter of which matches the diameter of the first hinge hole. The fixing plate 2 is hinged to the bottom plate of the fixing frame 1 via the first hinge rod. The top of the fixing plate 2 has a fixing groove 3, the height of which is not less than the height of the top plate of the fixing frame 1. The fixing groove 3 is fitted onto the top plate of the fixing frame 1. The fixing plate 2 below the fixing groove 3 has a threaded hole 4. A pressure rod 5 is threaded into the threaded hole 4. The two sides of the pressure rod 5 protrude from the threaded hole 4. By turning the pressure rod 5, the extension and retraction of the pressure rod 5 can be adjusted, thereby pressing and fixing the bamboo and wood placed in the fixing frame 1 onto the side plate of the fixing frame 1. A locking groove 6 is provided on the bottom surface of the top plate of the fixed frame 1, and a locking mechanism is provided in the locking groove 6. The locking mechanism includes an inverted L-shaped fixing block 7 and a spring 8 provided above the fixing block 7. The two ends of the spring 8 are respectively installed on the fixing block 7 and the fixed frame 1. One end of the spring 8 is installed on the side of the horizontal block of the fixing block 7 near the vertical block of the fixing block 7. The horizontal block of the fixing block 7 is located on the side of the vertical block of the fixing block 7 near the side plate of the fixed frame 1. The side of the horizontal block of the fixing block 7 away from the vertical block of the fixing block 7 is hinged to the fixed frame 1. A second hinge rod is provided on the fixing block 7. The second hinge rod is installed on the side of the horizontal block of the fixing block away from the vertical block of the fixing block 1. On one side of the vertical block of block 7, a second hinge hole is provided on the top plate of the fixing frame 1. The second hinge hole is movably fitted on the second hinge rod. The diameter of the second hinge rod matches the diameter of the second hinge hole. The fixing block 7 is hinged to the top plate of the fixing frame 1 through the second hinge rod. A guide groove 9 is provided on the bottom surface of the vertical block of the fixing block 7. The height of the guide groove 9 gradually increases along the direction away from the side plate of the fixing frame 1. The lower middle part of the guide groove 9 passes through the locking groove 6. The side wall of the vertical block of the fixing block 7 near the side plate of the fixing frame 1 contacts the fixing plate 2 to constrain the top of the fixing plate 2, thereby locking the top of the fixing plate 2.The guide groove 9 facilitates the locking of the top of the fixing plate 2, allowing for quick clamping and fixing of the bamboo and wood onto the fixing frame 1. Specifically, when the top of the fixing plate 2 is rotated from the side panel away from the fixing frame 1 to the side panel closer to the fixing frame 1, the guide groove 9 guides the fixing plate 2 to rotate towards the locking groove 6 from the part where the vertical block of the fixing block 7 protrudes. After the fixing plate 2 moves to the side where the vertical block of the fixing block 7 is closer to the side panel of the fixing frame 1, the spring force of the spring 8 drives the fixing block 7 to reset, thus using the fixing block 7 to constrain the top of the fixing plate 2, i.e., to lock the top of the fixing plate 2, thereby quickly locking the bamboo and wood onto the fixing frame 1.

[0022] In this embodiment, a pressure plate 10 is provided on the side of the pressure rod 5 near the side plate of the fixed frame 1, and a rotating mechanism is provided between the pressure plate 10 and the pressure rod 5. The rotating mechanism includes a cylinder 11 on the pressure plate 10, a disc 12 disposed inside the cylinder 11, and a circular cover 13 threaded onto the cylinder 11. The cylinder 11 is mounted on the pressure plate 10, the diameter of the disc 12 matches the inner diameter of the cylinder 11, the disc 12 is connected to the end of the pressure rod 5, and the diameter of the disc 12 is not less than the diameter of the pressure rod 5. The inner diameter of the circular cover 13 matches the outer diameter of the cylinder 11 so that the circular cover 13 can be threaded onto the cylinder 11. The circular cover 13 has a circular hole, which is movably fitted onto the cylinder 11. On the pressure rod 5, the diameter of the circular hole matches the diameter of the pressure rod, thereby constraining the disc 12 within the inner cavity of the cylinder 11, allowing the pressure rod 5 and the pressure plate 10 to be rotatably connected. A fixing rod 14 is provided on the side of the pressure plate 10 away from the fixed frame 1, with one end of the fixing rod 14 mounted on the pressure plate 10. A fixing hole is provided on the fixed plate 2, and the fixing rod 14 is movably fitted into the fixing hole. The diameter of the fixing rod 14 matches the diameter of the fixing hole, thereby preventing the pressure plate 10 from rotating relative to the fixed plate 2. Therefore, by turning the pressure rod 5, the pressure plate 10 can be moved along the direction of approaching or moving away from the side plate of the fixed frame 1, so as to press the bamboo and wood between the pressure plate 10 and the side plate of the fixed frame 1.

[0023] Specifically, a handle 15 is provided on the side of the pressure rod 5 away from the pressure plate 10. The handle 15 is installed at the end of the pressure rod 5 so as to turn the pressure rod 5. A fixing sleeve 16 is threaded on the pressure rod 5. The inner diameter of the fixing sleeve 16 matches the diameter of the pressure rod 5. One end of the fixing sleeve 16 is installed on the side of the fixing plate 2 away from the pressure plate 10, thereby reinforcing the threaded connection between the fixing plate 2 and the pressure plate 10 to improve the connection effect between the fixing plate 2 and the pressure rod 5. The top of the pressure plate 10 adopts an arc plate structure. The top of the pressure plate 10 gradually approaches the side plate of the fixing frame 1 from bottom to top so as to squeeze the bamboo and wood between the pressure plate 10 and the side plate of the fixing frame 1.

[0024] Please refer to the reference again. Figure 2 The locking groove 6 is located at the end of the top plate of the fixed frame 1 away from the side plate of the fixed frame 1. One side of the vertical block of the fixed block 7 protrudes from one end of the locking groove 6 so that the vertical block of the fixed block 7 can be pushed and pulled to rotate, thereby quickly releasing the locking of the fixed block 7 on the fixed plate 2.

[0025] In this embodiment, two support plates 17 are provided below the fixed frame 1. The top ends of the two support plates 17 are respectively installed on both sides of the bottom plate of the fixed frame 1. A plurality of rollers 18 are provided between the two support plates 17. The plurality of rollers 18 are rotatably installed on the support plates 17. The bottom ends of the plurality of rollers 18 are located on the same horizontal plane. A support seat 19 is provided below the rollers 18. A support block 20 is provided on the top surface of the support seat 19. The support block 20 is installed on the support seat 19. The two sides of the support block 20 are in contact with the side walls of the two support plates 17 respectively. With the help of the rolling of the rollers 18, the fixed frame 1 can be moved along the extension direction of the support block 20, so as to move the bamboo and wood clamped and fixed, so as to process the bamboo and wood.

[0026] Specifically, a vertical plate 21 is vertically arranged on the side of the fixed frame 1 away from the fixed plate 2. The bottom end of the vertical plate 21 is installed on the top surface of the support base 19. A limiting groove 22 is formed on the vertical plate 21. The extension direction of the limiting groove 22 and the extension direction of the vertical plate 21 are parallel to the extension direction of the support block 20. A limiting rod 23 is fitted inside the limiting groove 22. The diameter of the limiting rod 23 matches the groove height of the limiting groove 22. Both ends of the limiting rod 23 pass through the limiting groove 22. One end of the limiting rod 23 is installed on the fixed frame 1, and the other end of the limiting rod 23 is threaded with a nut 24. One side of the nut 24 contacts the side wall of the vertical plate 21 away from the fixed frame 1, so that the fixed frame 1 can be clamped and fixed on the vertical plate 21 by turning the nut 24, so that the fixed frame 1 can be fixed to the support base 19.

[0027] Please refer to it again. Figure 1 , 4 In section 6, a guide rail 25 is provided above the limiting rod 23. One side of the guide rail 25 is installed on the side wall of the upright plate 21 near the fixed frame 1. The extension direction of the guide rail 25 is parallel to the extension direction of the limiting groove 22. A slider 26 is movably mounted on the guide rail 25. A groove is provided on the slider 26. The cross-sectional shape of the groove matches the cross-sectional shape of the slider. One side of the slider 26 is installed on the fixed frame 1 to constrain the movement of the fixed frame 1, reduce the shaking of the fixed frame 1 during the movement, and thus improve the stability of the movement of the fixed frame 1.

[0028] The instructions for using this product are as follows: Figures 1 to 6As shown, firstly, the portion of the push-pull fixing block 7 protruding from the locking groove 6 rotates towards the locking groove 6 to quickly release the locking of the fixing block 7 onto the fixing plate 2, allowing the top of the push-pull fixing plate 2 to rotate from the top plate of the fixing frame 1, so that the top of the fixing plate 2 moves to the outside of the bottom plate of the fixing frame 1, thereby releasing the closure of the opening end of the fixing frame 1. Next, by passing the bamboo or wood to be processed through the opening end of the fixing frame 1 to securely place the bamboo or wood inside the fixing frame 1, the fixing plate 2 is rotated by pushing and pulling in the opposite direction, so that the fixing groove 3 opened on the fixing plate 2 fits onto the top plate of the fixing frame 1. During this process, the guide groove 9 can guide the fixing plate 2 to push the portion of the vertical block of the fixing block 7 protruding from the locking groove 6 to rotate towards the locking groove 6. After the fixing plate 2 moves to the side of the vertical block of the fixing block 7 near the side plate of the fixing frame 1, the spring force of the spring 8 drives the fixing block 7 to reset, so that the fixing block 7 can be used to constrain the top of the fixing plate 2, thereby closing the opening end of the fixing frame 1. Then, by turning the handle 15, the pressure rod 5 is rotated, causing it to move towards the side plate of the fixed frame 1. Under the constraint of the fixed rod 14 on the pressure plate 10, the pressure rod 5 pushes the pressure plate towards the side plate of the fixed frame 1 to clamp and fix the bamboo and wood placed inside the fixed frame 1. Finally, by using the rolling action of the roller 18, the fixed frame 1 and the bamboo and wood clamped and fixed inside the fixed frame 1 are moved to adjust the processing position of the bamboo and wood. After the position of the bamboo and wood is adjusted, the nut 24 is turned to fix the fixed frame 1 and the bamboo and wood clamped and fixed inside the fixed frame 1, so that the bamboo and wood can be processed by processing equipment such as cutting machines and grinding machines. After the bamboo and wood are processed, the handle 15 is turned in the opposite direction to move the pressure rod 5 along the side plate away from the fixed frame 1, thereby using the bamboo and wood to clamp and fix it. Then, the part of the fixed block 7 that passes through the locking groove 6 is pushed and pulled to rotate, so as to quickly release the locking of the fixed block 7 on the fixed plate 2, so that the bamboo and wood can be taken out from the fixed frame 1.

[0029] It should be noted that before using this product, the support base 19 must be installed on one side of the cutting machine, grinding machine or other processing equipment, so that the extension direction of the support block 20 faces the working area of ​​the cutting machine, grinding machine or other processing equipment.

[0030] In this embodiment, a clamping area for bamboo and wood is created by a fixed frame 1 with an opening on one side, allowing the bamboo and wood to be placed within this area. A fixed plate 2, hinged to the bottom plate of the fixed frame 1, allows the fixed plate 2 to rotate around the bottom plate. A spring 8 and a fixing block 7 on the top plate of the fixed frame 1 constrain the top of the fixed plate 2, thereby closing the opening of the fixed frame 1 and preventing the bamboo and wood from sliding out. Furthermore, the guide groove on the fixing block 7 guides the top of the fixed plate 2 for constraint, quickly closing the opening of the fixed frame 1 and simplifying the clamping operation. A pressure rod 5 threaded onto the fixed plate allows adjustment of its extension and retraction, pressing and fixing the bamboo and wood placed within the fixed frame 1 to the side wall of the fixed frame 1 to meet the clamping requirements.
