Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a measuring tool for measuring the deformation size of wood in high sashes of aluminum-clad wood windows. Background Art

[0002] In recent years, the demand for tall aluminum-clad wood windows has grown significantly. Generally, window sashes with a height of more than 2.4 meters are called high sashes. However, due to the easy deformation of wood itself, high sashes are prone to deformation after installation, which may cause the window sash to be loosely closed or the locking force to be too tight, thus affecting the user experience. It is worth noting that slight wood deformation is difficult to be directly identified by the human eye. The traditional tool for measuring the deformation of high sash wood is a plumb bob, but the plumb bob can only measure whether the high sash is deformed, not the amount of deformation, and the use of a plumb bob is not convenient in operation.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0025] Please refer to Figures 1 to 3As shown, a measuring tool for measuring the deformation size of wood in the high sash of aluminum-clad wood windows is shown, which includes: a measuring tool body 1, a first tensioning device 2, a second tensioning device 3, a first positioning block 4, a second positioning block 5 and a measuring line 6. The measuring tool body 1 is a rod-shaped structure; the front side of the measuring tool body 1 is sequentially installed with the first tensioning device 2, the first positioning block 4, the second positioning block 5 and the second tensioning device 3 from top to bottom; the first tensioning device 2 is close to the top end of the measuring tool body 1, and the second tensioning device 3 is close to the bottom end of the measuring tool body 1; the first positioning block 4 is close to the first tensioning device 2, and the second positioning block 5 is close to the bottom end of the measuring tool body 1; near the second tensioning device 3; one end of the measuring line 6 is connected to the first tensioning device 2, the other end of the measuring line 6 is connected to the second tensioning device 3, and the measuring line 6 passes through the first positioning block 4 and the second positioning block 5; the measuring tool body 1 is provided with a reserved hole 101 for a straight ruler to pass through, the reserved hole 101 passes horizontally through the front and rear sides of the measuring tool body 1, and the reserved hole 101 is located between the first positioning block 4 and the second positioning block 5; the front side surface of the first positioning block 4 and the front side surface of the second positioning block 5 are located in the same plane, and the plane is parallel to the measuring line 6 between the first positioning block 4 and the second positioning block 5.

[0026] Furthermore, in a preferred embodiment, the measuring tool body 1 is a hollow rod-shaped structure, which can relatively reduce the weight of the measuring tool body 1, save materials and make it easier to operate.

[0027] Furthermore, in a preferred embodiment, the measuring tool body 1 is a hollow rod-shaped structure made of aluminum. The specific gravity of aluminum is only one-third of that of steel, which makes it possible to reduce the weight of the structure while meeting the strength requirements.

[0028] Furthermore, in a preferred embodiment, the reserved hole 101 is located in the middle position of the measuring tool body 1. Since the deformation of the high fan wood is mostly convex or concave in the middle position, the ruler passing through the reserved hole 101 can be placed against the middle part of the high fan, thereby measuring whether the middle part is deformed.

[0029] Furthermore, in a preferred embodiment, the ruler is slidably installed in the reserved hole 101; the plane where the bottom wall of the reserved hole 101 is located is perpendicular to the plane where the front side surface of the first positioning block 4 is located.

[0030] Furthermore, in a preferred embodiment, the first tensioning device 2 and the second tensioning device 3 are components with the same structure; the first positioning block 4 and the second positioning block 5 are components with the same structure, so as to ensure the symmetry between the upper and lower components of the measuring tool.

[0031] Furthermore, in a preferred embodiment, the measuring line 6 in a straight line state between the first positioning block 4 and the second positioning block 5 does not contact the ruler to avoid the ruler inserted from the reserved hole 101 touching the measuring line 6, causing the measuring line 6 to deform and resulting in inaccurate measurement data.

[0032] Furthermore, in a preferred embodiment, the front side surface of the first positioning block 4 is provided with a first door leaf positioning surface 402, and the front side surface of the second positioning block 5 is provided with a second door leaf positioning surface 502. The first door leaf positioning surface 402 and the second door leaf positioning surface 502 are located in the same plane, and the plane is parallel to the measuring line 6 between the first positioning block 4 and the second positioning block 5. When in use, the first door leaf positioning surface 402 and the second door leaf positioning surface 502 are pressed against the surface of the high door leaf, and then a ruler is passed through the reserved hole 101, and the zero end of the ruler is pressed against the surface of the high door leaf. Because the distance between the measuring line 6 and the two door leaf positioning surfaces is a fixed length, if the size of the measuring line 6 on the straight ruler is different from the fixed length, it proves that the high door leaf has been deformed. Then, the size difference between the two can be calculated to obtain the deformation amount.

[0033] Furthermore, in a preferred embodiment, the measuring line 6 is preferably a fishing line. Fishing line is typically made of materials such as nylon, PE fiber, or carbon. These materials have good flexibility and a certain degree of elasticity, which means that the fishing line can be easily tightened. Fishing line is also highly wear-resistant and can be used for a long time without frequent replacement. Furthermore, the relatively thin diameter of the fishing line can improve measurement accuracy.

[0034] Furthermore, in a preferred embodiment, a C-shaped groove 102 is provided on the front side of the measuring tool body 1, and the first tensioning device 2 and the second tensioning device 3 are both detachably mounted within the C-shaped groove 102 via screws. The detachable design facilitates adjustment and tensioning of the measuring line 6 before measurement, thereby maintaining a straight line 6 between the first positioning block 4 and the second positioning block 5.

[0035] Furthermore, in a preferred embodiment, the first tensioning device 2 is provided with a first connecting hole 201 , one end of the measuring line 6 passes through the first connecting hole 201 , and one end of the measuring line 6 is fastened to the first tensioning device 2 .

[0036] Furthermore, in a preferred embodiment, the second tensioning device 3 is provided with a second connecting hole 301 , the other end of the measuring line 6 passes through the second connecting hole 301 , and the other end of the measuring line 6 is fastened to the second tensioning device 3 .

[0037] Furthermore, in a preferred embodiment, the first positioning block 4 is provided with a first through hole 401 for the measuring line 6 to pass through; and the second positioning block 5 is provided with a second through hole 501 for the measuring line 6 to pass through.

[0038] Furthermore, in a preferred embodiment, the first connecting hole 201 is located above and behind the first through hole 401; the second connecting hole 301 is located below and behind the second through hole 501; and the measuring line 6 abuts against the rear end in the first through hole 401 and the rear end in the second through hole 501.

[0039] Furthermore, in a preferred embodiment, the first through-hole 401 is teardrop-shaped, and the second through-hole 501 is also teardrop-shaped. The teardrop-shaped design of the first and second through-holes 401 and 501 facilitates the passage of the measuring wire 6 due to the wider end, while the pointed end facilitates the securing of the measuring wire 6. During assembly of the measuring tool, the measuring wire 6 is passed through the large end and then gradually slides toward the pointed end during tensioning.

[0040] Furthermore, in a preferred embodiment, the first positioning block 4 is provided with a first through hole 401 for the measuring line 6 to pass through; the first through hole 401 is in the shape of a water droplet, with the large end of the water droplet facing the front end and the pointed end of the water droplet facing the rear end; the second positioning block 5 is provided with a second through hole 501 for the measuring line 6 to pass through; the second through hole 501 is in the shape of a water droplet, with the large end of the water droplet facing the front end and the pointed end of the water droplet facing the rear end; the projections of the first through hole 401 and the second through hole 501 on the horizontal plane coincide with each other and have the same shape The distance between the tip of the first through hole 401 and the first door leaf positioning surface 402 is equal to the distance between the tip of the second through hole 501 and the second door leaf positioning surface 502. When the measuring line 6 is tightened, since one end of the measuring line 6 is pulled upward and backward by the first tensioning device 2, the measuring line 6 will abut the inner edge of the tip of the teardrop-shaped first through hole 401. Since the other end of the measuring line 6 is pulled downward and backward by the second tensioning device 3, the measuring line 6 will abut the inner edge of the tip of the teardrop-shaped second through hole 501. After being straightened, the measuring line 6 between the first positioning block 4 and the second positioning block 5 is parallel to the plane where the first door leaf positioning surface 402 and the second door leaf positioning surface 502 are located.

[0041] Furthermore, in a preferred embodiment, the first positioning block 4 is slidably connected to the C-shaped groove 102; the second positioning block 5 is slidably connected to the C-shaped groove 102. When assembling the measuring tool, it is convenient for the first positioning block 4 and the second positioning block 5 to slide into the top or bottom of the C-shaped groove 102, and it is convenient to adjust the distance between the first positioning block 4 and the second positioning block 5, thereby measuring window sashes of different heights. The first positioning block 4 is transitionally matched with the inner wall of the C-shaped groove 102. Due to the action of static friction, the first positioning block 4, which has been adjusted in position, is fixed in the C-shaped groove 102 and will not move during measurement; the second positioning block 5 is transitionally matched with the inner wall of the C-shaped groove 102. Due to static friction, the second positioning block 5, which has been adjusted in position, is fixed in the C-shaped groove 102 and will not move during measurement.

[0042] Furthermore, in a preferred embodiment, it also includes a first limit block, a second limit block, a third limit block and a fourth limit block, and the first limit block, the second limit block, the third limit block and the fourth limit block can be detachably installed in the C-shaped groove 102; the first limit block abuts against the top end of the first positioning block 4, and the second limit block abuts against the bottom end of the first positioning block 4; the third limit block abuts against the top end of the second positioning block 5, and the fourth limit block abuts against the bottom end of the second positioning block 5; the first limit block and the second limit block are used to fix the first positioning block 4, and the third limit block and the fourth limit block are used to fix the second positioning block 5.

[0043] Furthermore, in a preferred embodiment, the structures of the first limit block, the second limit block, the third limit block and the fourth limit block are the same as the structure of the first tensioning device 2. The purpose of this is to reduce the number of molds during production and facilitate the replacement of subsequent components.

[0044] Furthermore, in a preferred embodiment, the first tensioning device 2 is provided with a first slot 202, and the side wall of one end of the C-shaped slot 102 abuts against the inside of the first slot 202; the first tensioning device 2 is provided with a first top screw hole, and the top screw passes through the first top screw hole and abuts against the inner wall of the other end of the C-shaped slot 102; the first top screw hole obliquely passes through the first tensioning device 2, and the top screw is threadedly connected to the first top screw hole. When the top screw is installed, the tip of the top screw will abut against the inner wall of the other end of the C-shaped slot 102. When the top screw is continued to be screwed, the first tensioning device 2 moves in the opposite direction, and gradually the first slot 202 is tightened against the side wall of one end of the C-shaped slot 102. Since the measuring line 6 may be deformed and loose, the detachable design of the first tensioning device 2 can facilitate the adjustment and tightening of the measuring line 6. During adjustment, the top screw needs to be loosened. After loosening the top screw, the static friction between the inner wall of the first slot 202 and the side wall of one end of the C-shaped slot 102 disappears. Then, the upper and lower positions of the first tensioning device 2 are adjusted to tighten the measuring line 6.

[0045] Furthermore, in a preferred embodiment, the second tensioning device 3 is provided with a second card slot 302, and the side wall of one end of the C-shaped groove 102 abuts against the inside of the second card slot 302; the second tensioning device 3 is provided with a second top screw hole, and the top screw passes through the second top screw hole and abuts against the inner wall of the other end of the C-shaped groove 102; the second top screw hole obliquely passes through the second tensioning device 3, and the top screw is threadedly connected to the second top screw hole. When the top screw is installed, the tip of the top screw will abut against the inner wall of the other end of the C-shaped groove 102. When the top screw is continued to be screwed, the second tensioning device 3 moves in the opposite direction, and gradually the second card slot 302 is tightened against the side wall of one end of the C-shaped groove 102. Since the measuring line 6 may be deformed and loose, the detachable design of the second tensioning device 3 can facilitate the adjustment and tightening of the measuring line 6. During adjustment, the top screw needs to be loosened. After loosening the top screw, the static friction between the inner wall of the second slot 302 and the side wall of one end of the C-shaped slot 102 disappears. Then, the upper and lower positions of the second tensioning device 3 are adjusted to tighten the measuring line 6.

[0046] Furthermore, in a preferred embodiment, the length range of the measuring tool body 1 is 300cm to 320cm. Since the size of high fan wood on the market is mostly 2.4 meters to 3 meters. During measurement, the first positioning block 4 needs to be against the top position close to the high fan, and the second positioning block 5 needs to be against the bottom position close to the high fan; and the distance above the first positioning block 4 needs to be reserved for installing the first tensioning device 2, and the distance below the second positioning block 5 needs to be reserved for installing the second tensioning device 3. Therefore, the length range of the measuring tool body 1 is 300cm to 320cm, which is more in line with actual needs. For example, when the measuring tool body 1 is set to 300cm, the distance between the first positioning block 4 and the second positioning block 5 is set to 260cm, which is suitable for measuring a 270cm high fan.

[0047] Assembly process:

[0048] Slide the first positioning block 4 and the second positioning block 5 from the top or bottom of the measuring tool cylinder 1 into the C-shaped groove 102. After adjusting the positions of the first positioning block 4 and the second positioning block 5, install the first limit block, the second limit block, the third limit block, and the fourth limit block into the C-shaped groove 102 to secure the first positioning block 4 and the second positioning block 5. Next, connect one end of the measuring line 6 to the first tensioning device 2, and then secure the first tensioning device 2 to the C-shaped groove 102 with a top screw. Then, pass the other end of the measuring line 6 through the first through hole 401 and the second through hole 501, and then connect it to the second tensioning device 3, and then secure the second tensioning device 3 to the C-shaped groove 102 with a top screw. The measuring line 6 is connected to the first tensioning device 2 and the second tensioning device 3 in no particular order.

[0049] Working principle:

[0050] Place the first door leaf positioning surface 402 and the second door leaf positioning surface 502 against the surface of the high door leaf, then pass the ruler through the reserved hole 101, and place the zero end of the ruler against the surface of the high door leaf. Because the distance between the measuring line 6 and the two door leaf positioning surfaces is a fixed length, if the size of the measuring line 6 on the straight ruler is different from the fixed length, it proves that the high door leaf has been deformed. When the distance measured by the ruler is less than the fixed length distance, it means that the high door leaf has produced a convex deformation. Subtract the measured size from the fixed length size to get the convex deformation amount. When the distance measured by the ruler is greater than the fixed length distance, it means that the high door leaf has produced a concave deformation. Subtract the measured size from the fixed length size to get the concave deformation amount.

[0051] The above is only a preferred embodiment of the present invention, and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
