Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0042] For a multi-functional woodworking ruler, please refer to [link / reference]. Figure 1-5 As shown, it includes: a first body 100, a second body 200, a protractor 300, and a positioning component 400.
[0043] The first main body 100 has a first straight side 101 and a second side 102, the first straight side 101 and the second side 102 being opposite to each other; for example Figure 3 As shown, the first main body 100 is approximately the shape of a ruler, with its left and right sides arranged at an angle;
[0044] The second main body 200 has a first side 201, a second straight side 202 and a third side 203, and the second main body 200 is roughly triangular in shape;
[0045] Both the first body 100 and the second body 200 are equipped with scale lines, which can be used by users to measure length, assist in drawing straight lines, etc.
[0046] Specifically, such as Figure 1 As shown, the first straight edge 101 of the first body 100 is provided with a scale line, and the second straight edge 202 of the second body 200 is provided with a scale line; the scale line can be set on the front and back of the first body 100 and the second body 200, so that the woodworking ruler can be used on both sides.
[0047] The protractor 300 is mounted on the first body 100. The protractor 300 can be used to measure angles. Similarly, the front and back of the protractor 300 are provided with scale lines. The scale lines on the protractor 300 can include angle scale lines and length scale lines.
[0048] Optionally, the scale lines on the first body 100, the second body 200, and the protractor 300 can be in size or in inches to meet different usage needs.
[0049] The first body 100 and the second body 200 are rotatably connected, such as Figure 1 As shown, the first body 100 and the second body 200 are rotatably connected at approximately the left side, so that the right sides of the first body 100 and the second body 200 can be opened and closed relative to each other. The opening and closing of the first body 100 and the second body 200 relative to each other allows the multifunctional woodworking ruler to be deformed into different shapes, allowing for more measurement angles and the drawing of more straight lines at different angles, thus meeting different usage needs.
[0050] like Figure 2 and Figure 4 As shown, the protractor 300 is mounted on the second side 102 of the first body 100, and the protractor 300 extends in a direction away from the second side 102, specifically in an arc shape; the second body 200 is provided with a groove 210 for receiving the protractor 300.
[0051] The protractor 300 is arc-shaped to meet the needs of measuring angles and drawing arcs.
[0052] The first body 100 and the second body 200 can rotate relative to each other to a closed position and a maximum open position, wherein:
[0053] like Figure 1As shown, in the closed position, the first straight edge 101 and the second straight edge 202 form an acute angle α. Specifically, the right ends of the first straight edge 101 and the second straight edge 202 are connected, forming an acute angle. The first side edge 201 and the second side edge 102 fit together, making the structure more compact. The protractor 300 is housed in the groove 210, and the entire multi-functional woodworking ruler is roughly the shape of a triangle, forming a triangle. Users can measure lengths using the first straight edge 101 and the second straight edge 202, and simultaneously draw straight lines using the first straight edge 101, the second straight edge 202, and the third side edge 203.
[0054] The entire multi-functional woodworking ruler is more compact and small when closed, making it easy to carry.
[0055] like Figure 4 As shown, at the maximum open position, the first straight edge 101 and the second straight edge 202 are parallel; the first side edge 201 and the second side edge 102 form an acute angle β; the protractor 300 is pulled out of the groove 210; at this time, parallel lines can be drawn through the first straight edge 101 and the second straight edge 202, and angles can be measured and arc lines can be drawn through the protractor 300.
[0056] This multi-functional woodworking ruler can meet the needs of measuring angles, measuring lengths, drawing straight lines, drawing parallel lines, drawing perpendicular lines, and drawing included angles, offering a variety of functions.
[0057] The second body 200 is equipped with a positioning component 400 that acts on the protractor 300. When the first body 100 and the second body 200 rotate to any position within their rotatable range, the positioning component 400 presses against the protractor 300 to position the first body 100 and the second body 200. After positioning, it is convenient for users to perform measurements and drawings, and it prevents the first body 100 and the second body 200 from moving relative to each other during the measurement and drawing process. After positioning, the measurement and drawing are more accurate.
[0058] In addition, the multi-functional woodworking ruler is locked in the closed position by the positioning component 400 to prevent the first main body 100 and the second main body 200 from rotating and opening on their own, making it more convenient to store.
[0059] In this embodiment, both the second side 102 and the first side 201 are straight lines, which can help draw straight lines. In other embodiments, both the second side 102 and the first side 201 can be wavy lines, and the two wavy lines can correspond to the peaks and troughs, so that when the first body 100 and the second body 200 are in the closed position, the second side 102 and the first side 201 can fit tightly together.
[0060] In one embodiment, the groove 210 penetrates the front and back sides and the first side 201 of the second body 200, and a slot 211 communicating with the groove 210 is formed on the first side 201.
[0061] Specifically, the second body 200 has a certain thickness, so a slot 211 can be opened on the first side 201. The width of the slot 211 is roughly matched with the width of the protractor 300, so that the protractor 300 can pass smoothly through the slot 211.
[0062] The groove 210 extends through the front and back of the second body 200, allowing the scale lines on the protractor 300 to be visible from the front and back of the second body 200, while also reducing the weight of the second body 200.
[0063] At least one section of the groove 210 is an arc-shaped groove 212, which is designed to match the shape of the protractor 300, that is, the shape of the arc-shaped groove 212 is adapted to the shape of the protractor 300.
[0064] In addition, a straight groove 213 is provided at the end of the arc groove 212, that is, at the end away from the groove opening 211. The straight groove 213 can be used for drawing and also serves to reduce the weight of the second body 200.
[0065] like Figure 4 As shown, the first body 100 and the second body 200 are in their maximum open position, and the protractor 300 is exposed. However, the protractor 300 is not completely pulled out of the groove 210, and a part of it remains in the groove 210. This avoids the need to align the protractor 300 and the groove 210 when the first body 100 and the second body 200 are closed, and ensures that the protractor 300 can smoothly enter the groove 210 when closed.
[0066] Continue as Figure 4 As shown, the first body 100 and the second body 200 are in their most open positions, and the protractor 300 is exposed. The user can draw an arc by using the left or right side of the protractor 300.
[0067] In one embodiment, the positioning assembly 400 includes a positioning member 410 and a rotating member 420; the positioning member 410 is provided with a screw hole; the rotating member 420 is provided with a screw 421, the screw 421 is threaded into the screw hole, the rotating member 420 rotates in the forward direction to pass through the screw hole and press against the protractor 300; the rotating member 420 rotates in the reverse direction to make the screw 421 leave the protractor 300.
[0068] Specifically, the shape of the positioning component 410 is not limited, and its main function is to be installed on the second body 200, and it has a screw hole that connects to the groove 210; the rotating component 420 is cylindrical and has threads on its surface to prevent slipping and facilitate rotation.
[0069] Furthermore, a mounting groove 220 is provided on the first side 201 of the second main body 200. The mounting groove 220 includes: a first groove 221 and a second groove 222 that are connected to each other; the first groove 221 and the groove body 210 are connected; the positioning member 410 is installed in the first groove 221 and the screw hole is connected to the groove body 210; the rotating member 420 is located in the second groove 222.
[0070] Specifically, after the rotating part 420 is installed in the second groove 222, the screw thread of the rotating part 420 is installed in the screw hole. Since the positioning part 410 is fixedly installed in the first groove 221, and the screw thread of the rotating part 420 is installed in the screw hole, the rotating part 420 will not fall out when it is located in the second groove 222.
[0071] As described above, when the first body 100 and the second body 200 are in their maximum open position, and the protractor 300 is not fully pulled out of the slot 210, the rotating component 420 can rotate forward through the screw hole and press against the protractor 300, regardless of whether it is in the closed position, the maximum open position, or any position within the rotatable range, thus positioning the first body 100 and the second body 200 for easy drawing and measurement. When in the closed position, positioning the first body 100 and the second body 200 also prevents the multi-functional woodworking ruler from automatically opening during carrying. Furthermore, the rotating component 420 can rotate in the opposite direction to disengage the screw 421 from the protractor 300, allowing the first body 100 and the second body 200 to rotate relative to each other.
[0072] Furthermore, the length of the second groove 222 is less than the length of the rotating part 420. Whether the rotating part 420 rotates to press against the protractor 300 or rotates to loosen the protractor 300, the screw of the rotating part 420 cannot be completely disengaged from the screw hole, so as to prevent the rotating part 420 from disengaging from the second groove 222.
[0073] In one embodiment, when the first body 100 and the second body 200 are in the closed position, the first straight side 101, the second straight side 202 and the third side 203 constitute the three sides of the triangle ruler.
[0074] The first main body 100 and the second main body 200 are equipped with a level 500;
[0075] The first main body 100 is provided with a first level 501, which is parallel to the first straight side 101;
[0076] The second body 200 is provided with a second level 402, which is parallel to the second straight side 202;
[0077] The second main body 200 is provided with a third level 503, which is parallel to the third side 203;
[0078] like Figure 1 As shown, when the first body 100 and the second body 200 are in the closed position, the levelness can be measured regardless of which side is used. When the first body 100 and the second body 200 are in the maximum open position, the parallelism between the two planes can also be measured, as well as the perpendicularity between the two planes.
[0079] Specifically, such as Figure 3 As shown, both the first body 100 and the second body 200 have a hollowed-out groove for mounting the level 500. The hollowed-out groove runs through the front and back of the first body 100 and the second body 200, so that measurements can be taken from either side.
[0080] In one embodiment, the first body 100 is provided with a connecting plate 110, the connecting plate 110 is fixed to the second side 102 of the first body 100, and the second body 200 is provided with an embedding groove 230 corresponding to the connecting plate 110; the second body 200 and the connecting plate 110 are rotatably connected; when in the closed position, the connecting plate 110 is embedded in the embedding groove 230.
[0081] The connecting plate 110 is mainly designed to facilitate a rotatable connection between the first main body 100 and the second main body 200. A pin shaft can be provided at the connection point to achieve both limiting and connection.
[0082] In this embodiment, a connecting plate 110 is provided on the first main body 100 and an embedding groove 230 is provided on the second main body 200; alternatively, the embedding groove can be provided on the first main body 100 and the connecting plate can be provided on the second main body 200.
[0083] Furthermore, the second main body 200 is provided with a fourth side 204; such as Figure 1 As shown, when the first body 100 and the second body 200 are in the closed position, a notch 01 is formed at the corresponding connection position between the first body 100 and the second body 200; the main function of the notch 01 is to provide clearance, allowing the first body 100 and the second body 200 to rotate relative to each other; and as... Figure 4 As shown, when the first body 100 and the second body 200 are in their maximum open position, the fourth side 204 abuts against the second side 102, which serves to limit and support them.
[0084] Furthermore, the first body 100 and the second body 200 are provided with a plurality of through holes 02, through which the origin can be drawn.
[0085] like Figure 3 As shown, a support plate 240 can be installed on the third side 203. The width of the support plate 240 is greater than the thickness of the second main body 200, so that the multifunctional woodworking ruler can be placed vertically.
[0086] Both the first body 100 and the second body 200 can be made of precious metals, which have high hardness and wear resistance.
[0087] This utility model's multifunctional woodworking ruler has a variety of functions. When using it, you only need to carry one woodworking ruler to complete various operations such as measuring line degree, measuring angle, drawing arcs, drawing straight lines, measuring levelness, drawing perpendicular lines, and drawing parallel lines.
