Description

Technical Field

[0001] The utility model relates to the technical field of wooden flat boards, and more specifically to a board with a self-contained flatness adjustment rod. Background Art

[0002] Flat wood panels are often used in home decoration, such as cabinets and doors. The requirements for the surface flatness of such panels are getting higher and higher, especially for high-end decoration. Due to factors such as different moisture content in the wood, different stress of the panels, and panel cutting, the panels may bend and deform. This bending and deformation defect is difficult to adjust, and it is difficult to control the flatness of the product during later installation, commissioning, and use.

[0003] For the above-mentioned bending and deformation defects, most of them can only be disassembled later and the flatness can be corrected by applying force with equipment, which is a troublesome operation. Some of them use the back slot to install the straightening rod, which can fine-tune the length and achieve straightening by tensioning.

[0004] The straightening process of slotting and installing the straightener requires slotting on the surface of the board, which will break the surface of the board and affect the appearance. In addition, the straightness of the slot is required to be high. The burrs should be reduced after slotting, and the slot depth needs to be controlled, otherwise it will cause cracks on the board surface. This operation process is complicated. And during straightening, it is also necessary to control the bending direction of the straightening rod to ensure the correct direction of correction. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a plate with a straightening adjustment rod. The straightening plate does not need surface grooving.

[0024] The utility model is further described below in conjunction with specific implementation methods.

[0025] The plate produced by the utility model can be a single plate or a whole large plate. If it is a large plate, it will eventually need to be cut before being used for furniture, kitchen utensils, etc. In order to quickly straighten the plate after bending, each independent plate 1 needs to have at least one upper adjustment rod 21 and one lower adjustment rod 22 (such as Figure 1 As shown in the figure, the upper and lower adjustment rods (21, 22) are preferably arranged on the side away from the hinge of the plate, that is, on the opening and closing side. Therefore, for plates with large dimensions, according to the actual production design of the plates, multiple sets of upper adjustment rods 21 and lower adjustment rods 22 can be arranged on the plates to facilitate cutting and utilization of the plates in the width direction. It is necessary to ensure that one side of each plate after cutting contains the reserved upper and lower adjustment rods (21, 22).

[0026] Example 1

[0027] As shown in Figures and 3, a plate with a straight adjustment rod according to one embodiment of the utility model, each independent plate 1 is pre-embedded with at least two adjustment rods that penetrate the plate 1 along the length direction, the adjustment rods are solid profiles, and the adjustment rods are made of ductile and easy-to-cut materials, such as aluminum alloy, plastic, or other composite materials. The two adjustment rods are respectively called an upper adjustment rod 21 and a lower adjustment rod 22. In the thickness direction of the plate 1, the upper adjustment rod 21 and the lower adjustment rod 22 are respectively arranged on both sides of the plate 1 relative to the center line of the plate 1, that is, the upper adjustment rod 21 and the lower adjustment rod 22 are eccentrically arranged relative to the center of the plate 1. The upper adjustment rod 21 and the lower adjustment rod 22 have a certain hardness, and the plate 1 pre-embedded with the upper adjustment rod 21 and the lower adjustment rod 22 will have a stronger ability to resist bending and deformation than the pure wooden plate 1. However, the possibility of bending and deformation of the plate 1 still exists. In order to facilitate the deformation of the plate 1 in a timely manner during subsequent use, it is necessary to groove the two ends of the plate 1 so that the two ends of the upper adjustment rod 21 and the lower adjustment rod 22 are separated from the plate 1, so that the ends of the upper adjustment rod 21 and the lower adjustment rod 22 can be clamped, stretched or pressed to achieve the deformation of the adjustment rod. The cross-sectional shape of the upper adjustment rod 21 or the lower adjustment rod 22 can be circular, square or flat, but it needs to be compatible with the parts used for subsequent straightening. The flat bar shape is a structure with a flat end face, and the adjustment rod is a long bar as a whole, such as a rectangular cross-section, or a long bar structure with flat upper and lower surfaces and curved sides.

[0028] In this embodiment, in the thickness direction of the plate 1, the upper adjustment rod 21 and the lower adjustment rod 22 are symmetrically distributed with respect to the center line of the plate. The upper adjustment rod 21 and the lower adjustment rod 22 are both offset from the center line of the plate 1, and the upper adjustment rod 21 and the lower adjustment rod 22 are at the same distance from the center line of the plate, and the distance from the surface of the plate 1 on their respective sides is also the same. When the plate 1 bends toward one side, the adjustment rod on the other side is clamped for stretching, and the bent plate 1 is straightened and reset toward the other side by tensioning the adjustment rod; or force is applied to the adjustment rod on the same side as the bending direction, and the adjustment rod is pressed to drive the plate 1 to be straightened and reset toward the other side.

[0029] When straightening the plate 1 pre-embedded with the upper adjusting rod 21 and the lower adjusting rod 22, there is no need to cut a groove to place the straightener or to configure an additional straightening rod. The plate 1 can be straightened by simply stretching or pressing the upper adjusting rod 21 or the lower adjusting rod 22 pre-embedded in the plate 1. The straightening direction is easy to control and the operation is simple.

[0030] In practical applications, the form of the board 1 is not limited, and single-layer boards and composite boards are all possible. The type is also not limited, and solid wood boards, density boards, and particle boards are also possible. Figure 3 As shown, the composite panel generally includes an upper panel 11, a lower panel 12, and a core panel 13 filled between the upper panel 11 and the lower panel 12. In this composite panel form, an upper adjusting rod 21 and a lower adjusting rod 22 are pre-embedded in the core panel 13, and in the thickness direction, the upper adjusting rod 21 and the lower adjusting rod 22 are symmetrically arranged with respect to the center line of the core panel 13, and the upper adjusting rod 21 and the lower adjusting rod 22 are offset from the center of the core panel 13.

[0031] Example 2

[0032] The main difference between the second embodiment and the first embodiment is that the upper adjustment rod 21 and the lower adjustment rod 22 are arranged at different positions. Specifically, when the thickness of the plate 1 is not enough to allow the upper adjustment rod 21 and the lower adjustment rod 22 to be completely symmetrically arranged, the upper adjustment rod 21 and the lower adjustment rod 22 are arranged in a staggered manner, such as Figure 2 As shown, the misalignment distribution also needs to ensure that the upper adjustment rod 21 and the lower adjustment rod 22 are at equal distances from the center line of the plate, so the upper adjustment rod 21 and the lower adjustment rod 22 are at the same distance from the surface of the plate 1 on their respective sides. The plate 1 of this structure can also be straightened by stretching or pressing the upper and lower adjustment rods (21, 22) as mentioned in Example 1.

[0033] Example 3

[0034] In order to facilitate the straightening of subsequent products, for example, if the cabinet door is bent by using the plate 1 in the above embodiment, countersunk holes are processed at both ends of the plate 1 to form a sunken receiving groove 14 in order to avoid the trouble of subsequent straightening. Figure 4 As shown, the bottom of the accommodating groove 14 extends into the plate 1 to form a correction hole 15, which is located at the position of the upper and lower adjustment rods (21, 22). The aperture of the correction hole 15 needs to be larger and cannot be larger than the width of the end cover 3. However, after the correction hole 15 is opened, the hole edge of the correction hole 15 needs to surround the ends of the upper adjustment rod 21 and the lower adjustment rod 22, so that the two ends of the upper adjustment rod 21 and the lower adjustment rod 22 are separated from the plate 1, and the upper and lower adjustment rods (21, 22) have room for movement during straightening. When one adjustment rod is straightened, the other adjustment rod has room for accommodation. At least one end of the upper adjustment rod 21 and the lower adjustment rod 22 is connected to the straightening assembly, and both ends can also be connected to the straightening assembly. An end cover 3 is placed in the accommodating groove 14, and the end cover 3 is fixed to the plate 1 by screws, and one end of the straightening assembly is connected to the end cover 3. In this way, the ends of the upper adjusting rod 21 and the lower adjusting rod 22 are placed in the deviation correction hole 15, and only one straightening assembly and end cover 3 need to be configured at the same end, so that stretching straightening can be performed no matter which side the plate 1 is bent toward.

[0035] Specifically, in this embodiment, the straightening assembly includes an adjuster 41 and a screw rod 42. The cross-sections of the upper adjusting rod 21 and the lower adjusting rod 22 are circular. The ends of the upper adjusting rod 21 and the lower adjusting rod 22 are processed with a section of external thread. The adjuster 41 is placed in the deviation correction hole 15. The adjuster 41 has an internal thread. One end of the adjuster 41 is connected to the upper adjusting rod 21 or the lower adjusting rod 22 through a thread. The screw rod 42 passes through the end cover 3 and is connected to the other end of the adjuster 41 through a thread. In order to facilitate connection and installation, the outer end of the screw rod 42 adopts an inner hexagonal groove structure or a plum blossom groove structure, and the outer end of the screw rod 42 does not protrude from the end cover 3, which can avoid interference with the opening and closing of the door and improve the aesthetics.

[0036] The end of the upper adjusting rod 21 or the lower adjusting rod 22 enters the correction hole 15 and is connected to the adjuster 41 through a thread. The end cover 3 is installed and the screw 42 is screwed on to connect the screw 42 to the adjuster 41. By screwing the outer end of the screw 42, the position of the screw 42 relative to the adjuster 41 is adjusted to achieve tensioning of the upper adjusting rod 21 or the lower adjusting rod 22. According to the bending condition of the plate 1, the screw 42 is loosened or tightened to achieve the position change of the adjuster 41, thereby finally achieving straightening of the plate 1.

[0037] In this embodiment, in order to facilitate the fixation of the upper adjusting rod 21 or the lower adjusting rod 22 to the adjuster 41, the ends of the upper adjusting rod 21 and the lower adjusting rod 22 adopt an external thread structure. In actual experiments, this structure can be implemented, but the operation of this structure is not particularly convenient.

[0038] Example 4

[0039] The main difference between this embodiment and embodiment 3 is that the structure of the straightening assembly is different. Figure 5 As shown, in this embodiment, the straightening assembly includes a rivet puller 43 and a screw rod 2 44. The rivet puller 43 is placed in the deviation correction hole 15. The inner front end of the rivet puller 43 is tapered and is provided with a claw 45. The claw 45 is an existing structure. A claw 45 with three claws or a claw 45 with two claws can be used. The front end of the rivet puller 43 has a through hole 431 for the upper adjustment rod 21 or the lower adjustment rod 22 to pass through. A stop screw 46 is installed on the rear side of the claw 45 through a thread. A spring 47 can be provided between the claw 45 and the stop screw 46. The end of the upper adjustment rod 21 or the lower adjustment rod 22 is inserted into the claw 45 through the hole 431, and the stop screw 46 is locked. The claw 45 is pushed to the front end of the tapered hole of the rivet puller 43, and the upper adjustment rod 21 or the lower adjustment rod 22 is riveted by the claw 45. The screw rod 2 44 passes through the end cover 3 and is connected to the rear end of the rivet puller 43 through a thread.

[0040] The end of the upper adjusting rod 21 or the lower adjusting rod 22 enters the correction hole 15, and the end of the upper adjusting rod 21 or the lower adjusting rod 22 is inserted into the center of the pulling claw 45 through the through hole 431 at the front end of the rivet puller 43, and the stop screw 46 is tightened. The pulling claw 45 is pushed forward to the front end of the rivet puller 43, and the pulling claw 45 is tightened inward to rivet the upper adjusting rod 21 or the lower adjusting rod 22. After the end of the upper adjusting rod 21 or the lower adjusting rod 22 is fixed, the position of the rivet is changed by turning the screw 44, and the upper adjusting rod 21 or the lower adjusting rod 22 will bend to varying degrees to achieve straightening of the plate 1. The stop screw 46 can also be fixed after debugging. When the upper and lower adjusting rods (21, 22) are inserted, the spring 47 is compressed, and the claw 45 moves backward. When the claw 45 is opened and the upper and lower adjusting rods (21, 22) enter the center of the claw 45, the spring 47 automatically resets, and the claw 45 can also achieve automatic riveting, and then stretch straightening is performed, which is very simple to operate. The riveting method provided in this embodiment is more convenient than the threaded connection method of the upper and lower adjusting rods (21, 22) and the straightening assembly proposed in Example 3. By adopting the riveting method, the cross-sectional shape of the upper and lower adjusting rods (21, 22) can be circular, square, or flat.

[0041] Example 5

[0042] The main difference between this embodiment and embodiments 3 and 4 is that different straightening parts and straightening methods are used. Embodiments 3 and 4 use stretching straightening, while this embodiment uses a top pressing method to straighten the plate 1.

[0043] like Figure 6As shown, in this embodiment, it is necessary to process the two ends of the plate 1 to form recessed receiving holes 16, and the inner diameter of the receiving hole 16 needs to be larger, so that the hole edge of the receiving hole 16 surrounds the ends of the upper adjusting rod 21 and the lower adjusting rod 22, so that the two ends of the upper adjusting rod 21 and the lower adjusting rod 22 are separated from the plate 1. The internal threaded sleeve 5 is embedded in the receiving hole 16, and the internal threaded sleeve 5 is to be fixed together with the plate 1. The internal threaded sleeve 5 is threadedly assembled with a top screw 6, which is a screw with an external thread and no end. The top screw 6 has an internal hexagonal or hexagonal structure to facilitate the tool to apply force during straightening. A pressing block is placed between the top screw 6 and the upper adjusting rod 21 or the lower adjusting rod 22. In this embodiment, the pressing block is a wedge-shaped pressing block 7, and an inclined surface 71 is provided at one end close to the upper and lower adjusting rods (21, 22). A flat notch 72 is provided on the inclined surface 71, and the flat notch 72 can fix the end of the upper adjusting rod 21 or the lower adjusting rod 22. The contact surface between the wedge-shaped pressing block 7 and the top screw 6 is a vertical plane, and the top screw 6 is pressed tightly so that the wedge-shaped pressing block 7 presses the upper adjusting rod 21 or the lower adjusting rod 22.

[0044] The internal threaded sleeve 5 is fixed in the accommodating hole 16. When the plate 1 bends toward one side, force is applied to the upper adjusting rod 21 or the lower adjusting rod 22 on the other side. The wedge-shaped pressing block 7 is tightened by the top screw 6 to act on both ends of the upper adjusting rod 21 or the lower adjusting rod 22. When the two ends of the plate are subjected to force close to one side surface, eccentric force is generated, and the upper adjusting rod 21 or the lower adjusting rod 22 is gradually deformed, so that the plate 1 can be straightened.

[0045] Example 6

[0046] The main difference between this embodiment and embodiment 5 is that the structure of the top pressure block is different. Figure 7 As shown, in this embodiment, the pressing block is a sleeve 8, and the side of the sleeve 8 close to the upper adjustment rod 21 or the lower adjustment rod 22 is a vertical end face 81, and a sunken fixing groove 82 is provided on the vertical end face 81, and the fixing groove 82 is used to fix the end of the upper adjustment rod 21 or the lower adjustment rod 22. The contact surface between the sleeve 8 and the top screw 6 is a vertical plane, and the top screw 6 is pressed to make the sleeve 8 press the upper adjustment rod 21 or the lower adjustment rod 22. The force application method is the same as that of embodiment 5. By applying force, the plate 1 generates an eccentric force, and the upper adjustment rod 21 or the lower adjustment rod 22 gradually deforms, so that the plate 1 can be straightened.

[0047] The utility model provides a board 1 with two adjustment rods embedded inside. In the thickness direction of the board 1, the two adjustment rods are arranged up and down and are at equal distances from the two side surfaces of the board 1 and the center line of the board. The board 1 embedded with the upper and lower adjustment rods (21, 22) has a stronger ability to resist bending deformation than the pure wooden board 1. When straightening the board 1, there is no need to groove the surface or configure additional straightening rods. The upper and lower adjustment rods (21, 22) embedded in the board 1 can be directly used to stretch or press to achieve deformation and complete the straightening of the board 1. Because of the two adjustment rods arranged up and down, no matter which side the board 1 is facing, the straightening operation can be quickly performed, and the straightening direction is also easy to control. The ends of the upper and lower adjusting rods (21, 22) can be fixed by threaded connection or by direct riveting with claws 45. After the ends of the upper and lower adjusting rods (21, 22) are connected, it is only necessary to fine-tune screw rod 1 42 or screw rod 2 44 to achieve tensioning of the upper and lower adjusting rods (21, 22), or to press the upper and lower adjusting rods (21, 22) with top screws 6 and top pressure blocks to achieve deformation of the upper and lower adjusting rods (21, 22), thereby ultimately achieving the purpose of straightening the plate 1.

[0048] The above are only some embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, other modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
