Description

Technical Field

[0001] This utility model relates to the field of template support technology, specifically an adjustable wooden board support frame structure. Background Technology

[0002] In construction, furniture manufacturing, and interior decoration, the processing and installation of wooden boards often require the use of support frames for stable placement. Whether it's cutting, sanding, painting, or assembling the boards, support frames are needed to provide suitable support conditions to ensure operational accuracy and safety. Different sizes of wooden boards have different requirements for the height and angle of the support during processing.

[0003] However, existing wooden board support frames have significant limitations: most support structures are fixed and cannot adapt to wooden boards with different cross-sectional shapes, especially lacking effective clamping for non-rectangular cross-section wooden boards such as curved and trapezoidal boards, which are prone to sliding and displacement, and lack versatility. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable wooden board support frame structure, which solves the problem mentioned in the background art that the existing wooden board support structure is fixed and cannot adapt to wooden boards with different cross-sectional shapes, especially lacking effective clamping for non-rectangular cross-section wooden boards such as arc and trapezoidal boards, and has insufficient versatility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable wooden board support frame structure, including a base frame and a support block. The top of the support block is provided with a groove, and two rotating rods are rotatably connected between the front and rear inner walls of the groove. Transmission gears are fixedly connected to the surfaces of the two rotating rods and mesh with each other. An arc-shaped telescopic rod is fixedly connected to the center of the surfaces of the two rotating rods. A clamping rod is fixedly connected to the telescopic end of the arc-shaped telescopic rod. Two placement rods are fixedly connected to the top of the support block.

[0006] In this technical solution, rotating rods are set on the surface of the support block. The two rotating rods rotate in opposite directions, driving their respective arc-shaped telescopic rods and clamping rods to clamp the wooden board. Since the length and rotation angle can be freely set, it is also very convenient to clamp some non-rectangular cross-section wooden boards, thus improving the versatility of the device.

[0007] Preferably, a stud is rotatably connected to the top center of the base frame, the stud penetrates the surface of the lifting plate and is threadedly connected to the lifting plate, two limiting rods are fixedly connected to the bottom of the lifting plate, the bottom ends of the limiting rods penetrate the surface of the base frame and are slidably connected to the base frame, and the bottom ends of the stud penetrate the surface of the base frame and are fixedly connected to the adjusting wheel.

[0008] Preferably, the top of the lifting plate has two rectangular slots, and an adjusting rod is rotatably connected between the inner sidewalls of the rectangular slots. A drive gear is fixedly connected to the center of the surface of the adjusting rod, and the drive gear meshes with the convex teeth at the bottom of the support block.

[0009] Preferably, protruding plates are fixedly connected to the top edges of the lifting plates on both sides of the rectangular groove, and a support rod is rotatably connected between the protruding plates. The support rod passes through the support block and is fixedly connected to the support block.

[0011] Preferably, one end of one of the rotating rods passes through the side wall of the support block and is connected to the tail end of the drive shaft of the servo motor fixedly connected to the outer side wall of the support block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a rotating rod on the surface of the support block. The two rotating rods rotate in opposite directions, driving their respective arc-shaped telescopic rods and clamping rods to clamp the wooden board. Since the length and rotation angle can be freely set, it is also very convenient to clamp some non-rectangular cross-section wooden boards, thus improving the versatility of the device.

[0014] 2. This utility model sets a support block on the surface of a support rod, and the bottom of the support block is provided with protruding teeth. Under the drive of the adjusting rod and the drive gear, the angle of the upper support block can be adjusted, thereby driving the wooden board to change the angle.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] An adjustable wooden board support frame structure, see [link / reference]. Figures 1 to 4 The system includes a base frame 1 and a support block 8. The top of the support block 8 is provided with a groove 801. Two rotating rods 9 are rotatably connected between the front and rear inner walls of the groove 801. Transmission gears 901 are fixedly connected to the surfaces of the two rotating rods 9 and mesh with each other. One end of one of the rotating rods 9 passes through the side wall of the support block 8 and is connected to the tail end of the transmission shaft of the servo motor 10 fixedly connected to the outer wall of the support block 8. An arc-shaped telescopic rod 11 is fixedly connected to the center of the surface of each of the two rotating rods 9. A clamping rod 12 is fixedly connected to the telescopic end of the arc-shaped telescopic rod 11. Two placement rods 13 are fixedly connected to the top of the support block 8. The surfaces of the clamping rod 12 and the placement rod 13 are provided with anti-slip pads to increase the friction with the wooden board.

[0023] In the above technical solution, the wooden board is first placed on two placement rods 13 to form initial support. Then, the servo motor 10 is started, which drives one rotating rod 9 to rotate. Through two meshing transmission gears 901, the other rotating rod 9 rotates synchronously in the opposite direction, thereby driving the two arc-shaped telescopic rods 11 to swing synchronously inward or outward. At the same time, the telescopic rods 11 can adjust their extension length according to the thickness of the wooden board, so that the clamping rods 12 fit tightly against the surface of the wooden board. The device achieves symmetrical movement of the clamping rods 12 through gear transmission. Combined with the length adjustment of the arc-shaped telescopic rods 11, it can stably clamp rectangular wooden boards and is also suitable for non-rectangular cross-section wooden boards such as arc-shaped and trapezoidal boards. This solves the problem of unstable clamping of irregularly shaped wooden boards by traditional support frames and improves the versatility of the device.

[0024] Specifically, such as Figure 2 and Figure 3As shown, the top of the lifting plate 3 has two rectangular slots 303. An adjusting rod 5 is rotatably connected between the inner walls of the rectangular slots 303. A drive gear 6 is fixedly connected to the center of the surface of the adjusting rod 5. The drive gear 6 meshes with the protruding teeth 601 at the bottom of the support block 8. A protruding plate 302 is fixedly connected to the top edge of the lifting plate 3 on both sides of the rectangular slots 303. A support rod 4 is rotatably connected between the protruding plates 302. The support rod 4 passes through the support block 8 and is fixedly connected to the support block 8.

[0025] In the above technical solution, when it is necessary to adjust the support angle of the wooden board, the adjustment rod 5 is rotated, and the active gear 6 on its surface rotates accordingly. Through the meshing transmission with the bottom convex tooth 601 of the support block 8, the support block 8 is pushed to rotate around the support rod 4 as the axis, thereby changing the tilt angle of the wooden board. This achieves flexible adjustment of the support angle, which can meet the different angle requirements of different processing steps such as cutting and polishing of the wooden board, and solves the limitation of traditional support structures that can only fix the angle.

[0026] Furthermore, such as Figure 2 As shown, one end of the adjusting rod 5 passes through the side wall of the lifting plate 3 and is fixedly connected to the crank handle 501. One end of the support rod 4 passes through the surface of the protruding plate 302 and is provided with a threaded line. The end of the support rod 4 that passes through the protruding plate 302 is threadedly connected to a nut 7. The adjusting rod 5 can be easily rotated by the crank handle 501, which is more labor-saving than directly rotating the adjusting rod 5 and facilitates precise control of the angle adjustment range. When the angle of the support block 8 is adjusted to the correct position, the nut 7 at the end of the support rod 4 is tightened. The position of the support rod 4 is locked by the squeezing friction between the nut 7 and the protruding plate 302, thereby fixing the angle of the support block 8 and preventing the angle from shifting due to vibration during processing.

[0027] It is worth noting that, such as Figure 1 As shown, a stud 2 is rotatably connected to the top center of the base frame 1. The stud 2 penetrates the surface of the lifting plate 3 and is threadedly connected to the lifting plate 3. Two limiting rods 301 are fixedly connected to the bottom of the lifting plate 3. The bottom end of the limiting rod 301 penetrates the surface of the base frame 1 and is slidably connected to the base frame 1. The bottom end of the stud 2 penetrates the surface of the base frame 1 and is fixedly connected to the adjusting wheel 201. In use, if the height needs to be adjusted, the adjusting wheel 201 can be rotated to drive the stud 2 to rotate. The rotational motion of the stud 2 is converted into the vertical lifting motion of the lifting plate 3, which in turn drives the overall height adjustment of the upper support structure, thereby adapting to the height requirements of different operators and processing scenarios.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
