Description

Technical Field

[0001] The utility model relates to the technical field of composite boards, and particularly relates to a corner composite board. Background Art

[0002] In the fields of architecture, furniture manufacturing, industrial design, etc., it is often necessary to use corner composite boards to meet different structural and functional requirements.

[0003] However, traditional corner composite boards often have problems such as fixed and non-adjustable angles, or complex adjustment methods, low precision, and poor stability. This limits their application in diverse scenarios, making it impossible to flexibly adapt to various special angle requirements, and it is also difficult to ensure stable and reliable performance during long-term use after adjustment.

[0004] Therefore, we propose a corner composite board. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a corner composite board, in order to prevent the situation of fixed and non-adjustable angles, thereby improving the adaptability of the corner composite board in different scenarios; in order to avoid complex adjustment methods, thereby improving the convenience of operation; in order to overcome the defect of low precision, thereby meeting more precise angle requirements; in order to improve the deficiency of poor stability, thereby ensuring stable and reliable performance during long-term use after adjustment, and effectively solving the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A corner composite board, comprising a first composite board, a second composite board, a connecting arc plate, an adjusting mechanism and a telescopic mechanism. The first composite board and the second composite board are respectively arranged at both ends of the connecting arc plate, and the inner sides of the first composite board and the second composite board are connected by two groups of adjusting mechanisms. The adjusting mechanism comprises a first blade, a second blade and an axis. On the sides of the first blade and the second blade far away from the first composite board and the second composite board, a plurality of groups of connecting blocks arranged in a mirror image are fixedly connected. One end of the connecting block far away from the first blade and the second blade is fixedly connected with a connecting strip;

[0008] The connecting strips are connected by a telescopic mechanism, and the telescopic mechanism includes a parallel bracket, two groups of parallel support blocks are arranged inside the bracket, the middle part of the support block is rotatably connected with a screw rod, the middle part of the screw rod and is located between the two groups of support blocks and is fixedly connected with a hand wheel, a slide groove is provided inside the bracket and at the opposite end of the two groups of support blocks, a slider is slidably connected inside the slide groove, two groups of relatively output thread grooves are provided on the outside of the screw rod, both ends of the screw rod extend into the inside of the slide groove and the thread groove is threadedly connected to the slider, the end of the slider away from the support block is fixedly connected with a top block, and the end of the top block away from the bracket is rotatably connected to the end of the connecting strip away from the axis through a rotating shaft.

[0009] By adopting the above technical scheme, when it is necessary to adjust the angle between the first composite plate and the second composite plate, the hand wheel on the screw rod is turned. Since two sets of relatively output thread grooves are provided on the outer side of the screw rod, when the screw rod is rotated, it will drive the sliders threaded at both ends to move toward or away from each other in the slide grooves, and the movement of the slider will drive the top block to move. Since the top block is rotatably connected to the connecting strip through the rotating shaft, and the connecting strip is fixedly connected to the connecting blocks on the first page and the second page, the movement of the top block will push or pull the connecting strip, thereby changing the angle between the first page and the second page. The change in the angle between the first page and the second page will drive the first composite plate and the second composite plate to rotate relative to each other through the axis to achieve angle adjustment. In this way, the telescopic movement of the telescopic mechanism is utilized, and the transmission is transmitted through the connecting strip, the first page and the second page, so that the flexible adjustment of the angle of the corner composite plate is finally achieved.

[0010] Furthermore, guide rods are fixedly connected to both ends of the connecting arc plate, and plug-in grooves are provided at one end of the first composite plate and the second composite plate close to the connecting arc plate, and the guide rods are inserted into the plug-in grooves.

[0011] By adopting the above technical solution, when the first composite plate and the second composite plate are adjusted in angle, since the guide rod is inserted into the plug-in slot, the guide rod will move along the trajectory of the plug-in slot, so that the guide rod provides a clear guide for the rotation of the first composite plate and the second composite plate, ensuring that their rotation paths are accurate and stable without deviation or shaking; in addition, the displacement range of the first composite plate and the second composite plate during the angle adjustment process is limited to prevent excessive rotation or abnormal displacement, thereby ensuring the structural integrity and stability of the entire corner composite plate when adjusting the angle.

[0012] Furthermore, one end of the first sheet close to the axis is fixedly connected to a first sheet rolling and pressing column, and one end of the second sheet close to the axis is fixedly connected to a second sheet rolling and pressing column.

[0013] By adopting the above technical scheme, during the process of adjusting the angle, when the angle between the first page and the second page changes, the rolling and pressing columns play a role in enhancing the connection strength and stability. They can withstand a certain amount of pressure and tension, so that the connection between the first page and the second page and the axis is more firm, and the force and torque generated during the adjustment process are effectively transmitted to ensure the smoothness and precision of the adjustment action; at the same time, the existence of the rolling and pressing columns can also reduce the wear of the connection between the first page and the second page and the axis, thereby extending the service life of the components.

[0014] Furthermore, the first sheet rolling and pressing posts and the second sheet rolling and pressing posts are engaged with the axis through rolling and pressing.

[0015] By adopting the above technical scheme, when the first composite plate and the second composite plate are adjusted in angle, the included angle of the first sheet and the second sheet changes. Since the first sheet rolling and pressing columns and the second sheet rolling and pressing columns are engaged with the axis through rolling and pressing, this engaging structure enables the force generated by the first sheet and the second sheet to be effectively transmitted to the axis through the rolling and pressing columns during the angle adjustment process. The tight engagement of the rolling and pressing columns with the axis ensures stable and reliable force transmission, reduces force loss and deviation during the transmission process, thereby achieving accuracy and stability in the angle adjustment of the first composite plate and the second composite plate. At the same time, this engaging structure can also prevent the first sheet and the second sheet from being separated from the axis when subjected to force, thereby enhancing the reliability and durability of the entire structure.

[0016] Furthermore, a plurality of self-tapping screws are provided on the first leaf piece and the second leaf piece.

[0017] By adopting the above technical solution and through the tightening effect of the self-tapping screws, the first leaf and the second leaf can work more cooperatively when transmitting force and bearing load, thereby ensuring the accuracy and stability of the angle adjustment.

[0018] Furthermore, the first leaf sheet and the second leaf sheet are connected to the first composite board and the second composite board by self-tapping screws.

[0019] By adopting the above technical solution, during the angle adjustment process, the movement and force of the first leaf sheet and the second leaf sheet are transmitted to the first composite board and the second composite board through the self-tapping screws, thereby driving them to achieve angle changes; at the same time, the connection method of the self-tapping screws ensures the firmness of the connection between the first leaf sheet, the second leaf sheet and the first composite board and the second composite board, preventing loosening and falling off during long-term use or frequent angle adjustment, thereby ensuring the stability and reliability of the entire corner composite board structure.

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] In order to prevent the situation where the angle is fixed and cannot be adjusted, thereby improving the adaptability of the corner composite board in different scenarios; in order to avoid complex adjustment methods, thereby improving the convenience of operation; in order to overcome the defect of low precision, thereby meeting more delicate angle requirements; in order to improve the deficiency of poor stability, thereby ensuring stable and reliable performance during long-term use after adjustment, such as Figure 1 、 Figure 2 、 Figure 3As shown, a corner composite plate includes a first composite plate 1, a second composite plate 2, a connecting arc plate 3, an adjusting mechanism 22 and a telescopic mechanism 8. The first composite plate 1 and the second composite plate 2 are respectively arranged at both ends of the connecting arc plate 3, and the inner sides of the first composite plate 1 and the second composite plate 2 are connected by two groups of adjusting mechanisms 22. The adjusting mechanism 22 includes a first blade 4, a second blade 5 and an axis 16. On the sides of the first blade 4 and the second blade 5 away from the first composite plate 1 and the second composite plate 2, a plurality of groups of connection blocks 6 arranged in a mirror image are fixedly connected. One end of the connection block 6 away from the first blade 4 and the second blade 5 is fixedly connected with a connection bar 7;

[0029] The connection bars 7 are connected by a telescopic mechanism 8. The telescopic mechanism 8 includes parallel brackets 9. Inside the brackets 9, two groups of parallel support blocks 11 are arranged. In the middle of the support blocks 11, a lead screw 10 is rotatably connected. In the middle of the lead screw 10 and between the two support blocks 11, a handwheel 15 is fixedly connected. Inside the brackets 9 and at the opposite ends of the two support blocks 11, there are chutes 12. Inside the chutes 12, sliding blocks 13 are slidably connected. On the outer side of the lead screw 10, two groups of relatively output thread grooves are provided. Both ends of the lead screw 10 extend into the chutes 12 and the thread grooves are threadedly connected with the sliding blocks 13. One end of the sliding block 13 away from the support block 11 is fixedly connected with a top block 14. One end of the top block 14 away from the bracket 9 and one end of the connection bar 7 away from the axis 16 are rotatably connected through a rotating shaft.

[0030] When in use, when it is necessary to adjust the angle between the first composite plate 1 and the second composite plate 2, rotate the handwheel 15 on the lead screw 10. Since there are two groups of relatively output thread grooves on the outer side of the lead screw 10, when the lead screw 10 rotates, it will drive the sliding blocks 13 threadedly connected to its two ends to move towards or away from each other in the chute 12. The movement of the sliding block 13 will drive the movement of the top block 14. Since the top block 14 is rotatably connected to the connection bar 7 through a rotating shaft, and the connection bar 7 is fixedly connected to the connection blocks 6 on the first blade 4 and the second blade 5, the movement of the top block 14 will push or pull the connection bar 7, thereby changing the included angle between the first blade 4 and the second blade 5. The change in the included angle between the first blade 4 and the second blade 5 will drive the relative rotation of the first composite plate 1 and the second composite plate 2 through the axis 16, realizing the adjustment of the angle. In this way, by using the telescopic movement of the telescopic mechanism 8 and the transmission through the connection bar 7, the first blade 4 and the second blade 5, the flexible adjustment of the angle of the corner composite plate is finally realized.

[0031] Exemplarily, as Figure 1 shown, the present invention further includes that guide rods 20 are fixedly connected to both side edges of the two ends of the connecting arc plate 3. Insertion slots 21 are provided at one ends of the first composite plate 1 and the second composite plate 2 close to the connecting arc plate 3. The guide rods 20 are inserted into the insertion slots 21.

[0032] During use, when the first composite panel 1 and the second composite panel 2 are adjusted in angle, since the guide rod 20 is inserted into the insertion slot 21, the guide rod 20 will move along the trajectory of the insertion slot 21, so that the guide rod 20 provides a clear guide for the rotation of the first composite panel 1 and the second composite panel 2, ensuring that their rotation paths are accurate and stable without deviation or shaking; in addition, the displacement range of the first composite panel 1 and the second composite panel 2 during the angle adjustment process is limited to prevent excessive rotation or abnormal displacement, thereby ensuring the structural integrity and stability of the entire corner composite panel when adjusting the angle.

[0033] For example, Figure 1 , Figure 2 As shown, the utility model also includes that one end of the first sheet 4 close to the axis 16 is fixedly connected to a first sheet rolling column 17 , and one end of the second sheet 5 close to the axis 16 is fixedly connected to a second sheet rolling column 18 .

[0034] During use, during the process of adjusting the angle, when the angle between the first leaf 4 and the second leaf 5 changes, the rolling and pressing columns play a role in enhancing the connection strength and stability. They can withstand a certain amount of pressure and tension, so that the connection between the first leaf 4 and the second leaf 5 and the axis 16 is more firm, and the force and torque generated during the adjustment process are effectively transmitted to ensure the smoothness and precision of the adjustment action; at the same time, the existence of the rolling and pressing columns can also reduce the wear at the connection between the first leaf 4 and the second leaf 5 and the axis 16, thereby extending the service life of the components.

[0035] For example, Figure 1 , Figure 2 As shown, the utility model also includes that the first sheet rolling and pressing column 17 and the second sheet rolling and pressing column 18 are engaged with the shaft 16 by rolling and pressing.

[0036] During use, when the first composite panel 1 and the second composite panel 2 are adjusted in angle, the included angle between the first sheet 4 and the second sheet 5 changes. Since the first sheet rolling and pressing columns 17 and the second sheet rolling and pressing columns 18 are engaged with the axis 16 through rolling and pressing, this engaging structure enables the force generated by the first sheet 4 and the second sheet 5 to be effectively transmitted to the axis 16 through the rolling and pressing columns during the angle adjustment process. The tight engagement between the rolling and pressing columns and the axis 16 ensures stable and reliable force transmission, reduces force loss and deviation during the transmission process, thereby achieving accuracy and stability in the angle adjustment of the first composite panel 1 and the second composite panel 2. At the same time, this engaging structure can also prevent the first sheet 4 and the second sheet 5 from being separated from the axis 16 when subjected to force, thereby enhancing the reliability and durability of the entire structure.

[0037] For example, Figure 1 , Figure 2As shown, the utility model further includes that a number of self-tapping screws 19 are provided on the first blade 4 and the second blade 5.

[0038] During use, due to the fastening effect of the self-tapping screws 19, the first blade 4 and the second blade 5 can work more cooperatively when transmitting force and bearing load, ensuring the accuracy and stability of angle adjustment.

[0039] Exemplarily, as Figure 2 shown, the utility model further includes that the first blade 4 and the second blade 5 are connected to the first composite board 1 and the second composite board 2 through the self-tapping screws 19.

[0040] During use, during the angle adjustment process, the movement and force of the first blade 4 and the second blade 5 are transmitted to the first composite board 1 and the second composite board 2 through the self-tapping screws 19, thereby driving them to achieve angle change; at the same time, the connection method of the self-tapping screws 19 ensures the firmness of the connection between the first blade 4, the second blade 5 and the first composite board 1, the second composite board 2, preventing loosening and falling off during long-term use or frequent angle adjustment, and ensuring the stability and reliability of the entire corner composite board structure.

[0041] It should be noted that the utility model is a corner composite board. Rotate the handwheel 15 on the rotating lead screw 10 to make the lead screw 10 rotate. The rotation of the lead screw 10 drives the sliders 13 at both ends to move towards or away from each other in the chute 12. The movement of the sliders 13 pushes or pulls the top block 14, and the top block 14 drives the first blade 4 and the second blade 5 to move through the connecting bar 7, changing the included angle between them. When the first composite board 1 and the second composite board 2 reach the required angle, stop rotating the handwheel 15.

[0042] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model.
