Description

Technical Field

[0001] The utility model belongs to the technical field of measuring tool ruler accessories, in particular to a multi-angle precision woodworking ruler clamp. Background Art

[0002] In the process of woodworking, it is necessary to measure the length, width and height of the wooden board or the outer diameter of the wooden stick. In order to achieve these functions, multiple rulers are needed, which greatly increases the cost and reduces the measurement efficiency.

[0003] For example, a civil engineering measuring ruler with patent application number 201620108213.0 comprises a first horizontal portion, a first vertical portion, a second horizontal portion and a second vertical portion located in the same plane, a first scale line is arranged on the front of the first horizontal portion, a second scale line is arranged on the front of the second vertical portion, the first horizontal portion and the first vertical portion are an integral structure, and the second horizontal portion and the second vertical portion are an integral structure. This civil engineering measuring ruler can not only perform horizontal and vertical measurements, but also make the first horizontal portion and the second vertical portion reach different measuring points by moving the second horizontal portion, thereby improving the accuracy of a single measurement and reducing the difficulty of measurement.

[0004] However, the above measuring ruler cannot complete the measurement of the outer diameter of the wooden stick, and cannot be stable during measurement, so there will be some deviations in the measurement and the accuracy is poor. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a multi-angle precision woodworking ruler clamp, which can measure the length, width and height of a wooden board, can measure the inclined length, and can also measure the outer diameter of a wooden stick.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-angle precision woodworking ruler clamp, comprising a ruler block and a ruler, one end of the ruler block is an inclined surface, the upper surface of the ruler block is provided with a placement opening for placing the ruler, one side of the ruler block is provided with a screw hole, a matching clamping bolt is arranged in the screw hole, and the upper surface of the ruler block on the side of the placement opening is provided with a screw hole, and a matching clamping bolt is arranged in the screw hole.

[0007] Optionally, the inner end of the screw hole 1 is located in the placement opening, and the screw hole 1 located in the placement opening is exposed to the outside.

[0008] Optionally, a round pressure block is fixed to the upper end of the second clamping bolt.

[0009] Optionally, the depth of the placement opening is the same as or less than the thickness of a ruler to be used.

[0010] Optionally, a plurality of friction strips are fixed to the outer side surface of the circular pressing block.

[0011] Optionally, the depth of the screw hole 1 and the length of the clamping bolt 1 can be adjusted according to the ratio of a ruler to the placement opening.

[0012] Optionally, magnets are symmetrically installed in the placement opening.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0014] The ruler is stably clamped by the clamping bolts 1 and 2. When used with a straight ruler, the length, width, height and inclined edge of the wooden board can be measured. When used with a square ruler, the outer diameter of the wooden stick can be measured.

[0015] When measuring, the edge of the clamp block can be placed against a wooden board or a wooden stick to ensure stable measurement of the ruler. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0024] refer to Figure 1-2 A multi-angle precision woodworking ruler clamp comprises a ruler block 1, one end of which is arranged as an inclined surface. When an inclined length measurement is to be performed, the inclined surface can be abutted against an object to be measured to achieve the purpose of stable measurement.

[0025] A placement opening 2 is provided on the upper surface of the clamp block 1. When measurement is required, a ruler to be used together is placed in the placement opening 2, thereby achieving the primary condition of stably clamping the ruler.

[0026] The angle of the inclined surface can be adjusted according to the inclination of the length to be measured. During production, the clamp block 1 is a plastic part, which is integrally injection molded and requires a designated mold. A mold with a corresponding inclined surface can be selected before injection molding.

[0027] A screw hole 3 is provided on one side of the clamp block 1, and the inner end of the screw hole 3 is located in the placement opening 2. The screw hole 3 in the placement opening 2 is exposed to the outside, and a clamping bolt 4 is provided at the screw hole 3. The clamping bolt 4 cooperates with the clamp block 1 through the screw hole 3, and the clamping bolt 4 is gradually screwed into the placement opening 2 along the screw hole 3.

[0028] After the inner flat end of the clamping bolt 4 contacts the ruler, it drives the ruler to gradually move toward the inner wall of the placement opening 2 until the ruler is stably pressed in the placement opening 2, giving the ruler a horizontal clamping force.

[0029] When part of the clamping bolt 4 is in the placement opening 2, the state of this part of the clamping bolt 4 is that part of it is in the screw hole 3 and part of it is outside the screw hole 3. The purpose of the design here is: there are many shapes of existing rulers, one is a regular rectangular parallelepiped with several planes, and the other is an arc surface near the scale, and the thickness gradually decreases toward the outside. The cooperation between the clamping bolt 4 and the screw hole 3 can achieve the clamping of various rulers. If the clamping bolt 4 is in the placement opening 2 as a whole, the clamping bolt 4 will contact the arc surface of the ruler, resulting in the inability to clamp horizontally and stably.

[0030] Furthermore, the depth of the screw hole 3 and the length of the clamping bolt 4 can be adjusted according to the ratio of the ruler to the placement opening 2, so as to be able to clamp rulers of different widths.

[0031] refer to Figure 2 A screw hole 25 is provided on the upper surface of the clamp block 1. The screw hole 25 is located between the placement opening 2 and the inclined surface, and the screw hole 25 is close to the placement opening 2. A clamping bolt 26 is provided at the screw hole 25. The clamping bolt 26 is gradually screwed inward along the screw hole 25, and the clamping bolt 26 cooperates with the clamp block 1 through the screw hole 25.

[0032] A round pressure block 7 is fixed to the upper end of the clamping bolt 6. When the clamping bolt 6 is in the screw hole 5, one side of the round pressure block 7 will be exposed on the upper side of the placement opening 2. It is worth noting that the depth of the placement opening 2 is consistent or slightly smaller than the thickness of the ruler to be used, ensuring that when the clamping bolt 6 is gradually screwed into the screw hole 5, the round pressure block 7 can move with the clamping bolt 6, and the round pressure block 7 can press the ruler to give the ruler a vertical clamping force.

[0033] By applying horizontal and vertical pressing forces to the ruler placed in the placement opening 2, a stable clamping of the ruler is achieved, so that the ruler will not easily fall off the clamping ruler block 1, thereby ensuring stability during measurement.

[0034] A magnet 10 is symmetrically installed in the placement opening 2. When a steel ruler is matched with the clamp block 1, the magnet 10 can adsorb the steel ruler to further fix the steel ruler.

[0035] Furthermore, a plurality of friction strips are fixed to the outer side surface of the round pressing block 7. When the round pressing block 7 is rotated manually, after the hand touches the round pressing block 7, the friction between the round pressing block 7 and the fingers can be increased, which can facilitate the rotation of the round pressing block 7.

[0036] The following are four measurement examples:

[0037] The first method is to measure the horizontal length of the board, combined with the instructions Figure 3 After clamping the ruler, place the long side of the clamp block on the workpiece to be measured, move the clamp block with the ruler to the specified measuring position, and finally measure. The difference between the scales is the final measured length.

[0038] The second method is to measure the inclined length of the board, combined with the Figure 4 After clamping the ruler, place the inclined surface of the clamp block on the workpiece to be measured, move the clamp block with the ruler to the specified measuring position, and finally measure. The difference between the scales is the final measured length.

[0039] The third method is to measure the thickness of the wood board, combined with the instructions Figure 5 After clamping the ruler, the long side of the clamp block is attached to the workpiece to be measured, and the measuring side of the ruler is attached to the thickness side of the workpiece to be measured. Move the clamp block with the ruler to the specified measuring position, align the 0 scale of the ruler with the lower surface of the workpiece to be measured, and finally measure. The final measured length is the end scale.

[0040] The fourth method is to measure the outer diameter of the wooden stick, combined with the Figure 6, place one side of the square ruler in the placement opening on the clamp block, place the wooden stick between the clamp block and the square ruler, then pull the square ruler until the square ruler and the clamp block clamp the wooden stick, and finally measure. The difference between the scales on the side of the clamp block and the long side of the square ruler close to the clamp block is the final measured length.

[0041] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0042] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0043] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field.
