Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a portable geometric measurement device. Background Technology

[0002] Geometric quantities are spatial quantities used to characterize the size, shape, and position of an object. They are mainly used to describe the geometric characteristics of an object and have wide applications in many fields, such as mathematics, physics, and engineering.

[0003] A search revealed a Chinese patent (CN222912589U) disclosing a portable geometric measurement device. The device includes a storage box with a handle near the center of its top surface. A detachable door on one side of the storage box allows for opening and closing. The device also includes a measuring mechanism housed inside the storage box. This mechanism comprises a base with a support plate fixedly mounted on its top surface. A slide rail is fixedly mounted on one side of the support plate, and a slider is slidably mounted on the outer surface of the slide rail. A connecting plate is fixedly mounted on one side of the slider, and an extension plate is fixedly mounted on one side of the connecting plate, with a first graduation on one side of the extension plate. A fixing plate is fixedly mounted on the top surface of the base, with a second graduation on one side. This portable geometric measurement device facilitates simultaneous measurement of the height, length, and width of objects, providing stable, accurate, and efficient measurements.

[0004] The aforementioned patented technology facilitates the simultaneous measurement of the height, length, and width of an object by setting up a measuring mechanism. However, in actual use, the measurement range is determined by the physical length and width of the base. If the object's length exceeds the base's length or its width exceeds the maximum distance between the support plate and the clamping plate, the object cannot be stably placed on the base, and the measurement cannot be completed, resulting in low applicability of the device. Therefore, a portable geometric measurement device is proposed. Utility Model Content

[0005] The technical problem to be solved by this application is that the measurement range is determined by the physical length and width of the base. If the length of the object exceeds the length of the base and the width exceeds the maximum distance between the support plate and the clamping plate, the object cannot be stably placed on the base, and the measurement cannot be completed, resulting in low applicability of the device.

[0006] To address the aforementioned technical problems, this application provides a portable geometric measurement device, including a fixed base. Measuring rulers are disposed on the right side, rear side, and top of the fixed base. The right-side measuring ruler, rear-side measuring ruler, and top measuring ruler are used to measure the length, width, and height of the object to be measured, respectively. An extension ruler is hinged to the end of the measuring ruler. Two limiting components are disposed on the outside of the measuring ruler. One limiting component is used to limit the extension ruler and the measuring ruler, and the other limiting component is used to move to the edge of the object to be measured, so that one end of the limiting component corresponds to the edge of the object to be measured, thereby taking a reading based on the position of one end of the limiting component on the measuring ruler or the extension ruler.

[0007] In some embodiments, the limiting component includes a hollow frame movably fitted outside the measuring ruler and the extension ruler, a threaded rod threaded through one side of the hollow frame, a knob connected to one end of the threaded rod outside the hollow frame, and an abutment block rotatably connected to the other end of the threaded rod away from the knob.

[0008] In some embodiments, a rotating seat is provided on the rear and top outer surfaces of the fixed seat. A support shaft is rotatably connected to the outer surface of the rotating seat, and a rotating plate is rotatably sleeved on the outer surface of the support shaft. The top measuring scale and the rear measuring scale are respectively connected to the two rotating plates.

[0009] In some embodiments, the outer surface of the support shaft is provided with threads, and a wing nut is threaded onto the outer surface of the threads. An arc-shaped cylinder is movably inserted through the rotating seat on the side facing the wing nut. An abutment plate is fitted onto the outer surface of the support shaft. The rotating plate is movably fitted with the outer surface of the abutment plate, and the arc-shaped cylinder is movably fitted with the other side of the rotating plate.

[0010] In some embodiments, a baffle is provided on the right outer surface of the fixing base, and the front side of the object to be measured abuts against the baffle to perform the measurement.

[0011] In some embodiments, the scale lines on the measuring ruler and the extension ruler are continuously arranged.

[0012] In some embodiments, the zero mark of the measuring scale on the right is located at the connection between the measuring scale on the right and the fixed base, the zero mark of the measuring scale on the upper side is located at the bottom of the fixed base, and the zero mark of the measuring scale on the rear side is located on the rear side of the baffle.

[0013] In some embodiments, the length of the measuring ruler is greater than the length of the extension ruler.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. This utility model expands the measurement range by setting an extendable extension ruler on the measuring ruler, enabling the measurement of larger objects. The extension ruler and the measuring ruler are limited by a limiting component, thereby increasing the measurement range of the measuring device and improving its applicability.

[0016] 2. By setting a rotating base, in conjunction with a wing nut, abutment plate and arc-shaped cylinder, this utility model enables the measuring rulers in the width direction and height direction to rotate, rotating them to the same orientation as the ruler in the length direction, reducing the overall space occupied and making it easier to carry the measuring device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-5This utility model provides a technical solution: a portable geometric measurement device, including a fixed base 1. Measuring rulers 3 are disposed on the right side, rear side, and top of the fixed base 1. The right-side measuring ruler 3, rear-side measuring ruler 3, and top measuring ruler 3 are used to measure the length, width, and height of the object to be measured, respectively. An extension ruler 31 is hinged to the end of the measuring ruler 3. Two limiting components are disposed on the outside of the measuring ruler 3. One limiting component is used to limit the extension ruler 31 and the measuring ruler 3, and the other limiting component is used to move to the edge of the object to be measured, such that one of the limiting components... The end corresponds to the edge of the object to be measured, so that the reading is taken according to the position of one end of the limiting component on the measuring ruler 3 or the extension ruler 31. Specifically, the length, width and height of the object to be measured are measured by multiple measuring rulers 3 respectively. When it is necessary to extend the extension ruler 31, the extension ruler 31 and the measuring ruler 3 are rotated under the action of the hinge to extend the extension ruler 31. The limiting component limits the measurement ruler 3 and the extension ruler 31. The measuring ruler 3 or the extension ruler 31 is moved to the edge of the object to be measured by another limiting component to take the reading.

[0026] Example 2: Based on Example 1, such as Figures 1-5 As shown, the limiting assembly includes a hollow frame 4 movably sleeved outside the measuring ruler 3 and the extension ruler 31. A threaded rod 41 is threaded through one side of the hollow frame 4. A knob 42 is connected to one end of the threaded rod 41 outside the hollow frame 4, and an abutment block 43 is rotatably connected to the other end of the threaded rod 41 away from the knob 42. Specifically, the hollow frame 4 limits the measuring ruler 3 and the extension ruler 31 to prevent them from expanding independently. By rotating the knob 42, the knob 42 drives the threaded rod 41 to move, and the threaded rod 41 drives the abutment block 43 to move, so that one end of the abutment block 43 abuts against the connection between the extension ruler 31 and the measuring ruler 3, and the other end of the hollow frame 4 abuts against the measuring ruler 3 or the extension ruler 31, thus limiting the connection between the extension ruler 31 and the measuring ruler 3 in conjunction with the abutment block 43.

[0027] Example 3: Based on Example 1, such as Figures 1-5 As shown, rotating seats 2 are provided on the rear and top outer surfaces of the fixed seat 1. A support shaft 21 is rotatably connected to the outer surface of the rotating seat 2. A rotating plate 22 is rotatably sleeved on the outer surface of the support shaft 21. The top measuring ruler 3 and the rear measuring ruler 3 are respectively connected to the two rotating plates 22. Specifically, when force is applied to the measuring ruler 3, the rotating plate 22 rotates on the surface of the support shaft 21, thereby adjusting the direction of the measuring ruler 3 and expanding or retracting the measuring ruler 3.

[0028] Example 4: Based on Example 1, as follows Figures 1-5As shown, the outer surface of the support shaft 21 is provided with threads 25, and a wing nut 26 is threaded onto the outer surface of the threads 25. An arc-shaped cylinder 24 is movably inserted through the rotating seat 2 on the side facing the wing nut 26. An abutment plate 23 is fitted onto the outer surface of the support shaft 21. The rotating plate 22 is in movable contact with the outer surface of the abutment plate 23, and the arc-shaped cylinder 24 is in movable contact with the other side of the rotating plate 22. Specifically, loosening the wing nut 26 allows it to move on the threads 25, thus stopping the wing nut 26 from pressing against the arc-shaped cylinder 24. The arc-shaped cylinder 24 creates a gap on the surface of the rotating plate 22, which reduces the friction between the arc-shaped cylinder and the abutment plate 23 and the rotating plate 22. This allows the measuring scale 3 at the rotating seat 2 to be slightly stressed and rotate, thereby adjusting the direction of the measuring scale 3. After adjustment, the wing nut 26 is tightened, which causes the arc-shaped cylinder 24 to press against the rotating plate 22, increasing the friction between the rotating plate 22 and the abutment plate 23. This prevents the rotating plate 22 from easily rotating under external force, thus allowing the measuring scale 3 to be expanded or retracted. When retracted, it reduces the space occupied and is easy to carry.

[0029] Example 5: Based on Example 1, as follows Figures 1-5 As shown, a baffle 11 is provided on the right outer surface of the fixed base 1. The front side of the object to be measured abuts against the baffle 11 for measurement. Specifically, when measuring, the fixed base 1 is placed below the front left side of the object to be measured, so that the rear side of the baffle 11 abuts against the front side of the object to be measured. The baffle 11 is located behind the right-side direction knob 42, thereby avoiding the knob 42 from obstructing the baffle 11.

[0030] Example 6: Based on Example 1, as follows Figures 1-5 As shown, the scale lines on the measuring ruler 3 and the extension ruler 31 are continuously set. Specifically, when the measuring ruler 3 and the extension ruler 31 are extended, the scale lines are continuous, so the reading on the extension ruler 31 when measuring the object is the size of the object.

[0031] Example 7: Based on Example 1, as follows Figures 1-5As shown, the zero mark of the right measuring ruler 3 is located at the connection between the right measuring ruler 3 and the fixed base 1, the zero mark of the upper measuring ruler 3 is located at the bottom of the fixed base 1, and the zero mark of the rear measuring ruler 3 is located on the rear side of the baffle 11. Specifically, during measurement, the fixed base 1 is placed at the lower left front corner of the object to be measured, and the rear side of the baffle 11 is in contact with the front side of the object to be measured. At this time, the zero mark of the width direction of the object to be measured is located on the rear side of the baffle 11, the right side of the fixed base 1 is in contact with the left side of the object to be measured, and the right side of the fixed base 1 is in contact with the left side of the object to be measured. At this time, the zero mark of the length direction of the object to be measured is located on the right side of the fixed base 1, and the bottom of the object to be measured and the bottom of the fixed base 1 are on the same horizontal plane, so that the zero mark of the height direction of the object to be measured is located below the fixed base 1. Thus, the readings of each measuring ruler 3 or extension ruler 31 are the length, width, and height of the object to be measured.

[0032] Example 8: Based on Example 1, as follows Figures 1-5 As shown, the length of the measuring ruler 3 is greater than the length of the extension ruler 31. Specifically, the length of the measuring ruler 3 is greater than the length of the extension ruler 31, so that when the extension ruler 31 is folded, it can be located above the measuring ruler 3, and there is a gap between the end of the measuring ruler 3 facing the fixed base 1 and the extension ruler 31. When the extension ruler 31 is extended, the hollow frame 4 is moved to the side of the measuring ruler 3 close to the fixed base 1, so that the hollow frame 4 is detached from the surface of the extension ruler 31, so that the extension ruler 31 can be rotated and extended.

[0033] Based on the above embodiments, the following is the complete working principle of the above embodiments: During use, when measuring, the length, width, and height of the object are measured using three measuring rulers 3 respectively. When measuring a large object, if the range of the measuring rulers 3 is insufficient, the limiting component is moved to the end of the measuring ruler 3 facing the fixed base 1, releasing the limiting on the extension ruler 31 and the measuring ruler 3. This causes the extension ruler 31 and the measuring ruler 3 to rotate relative to each other under the action of the hinge, rotating the extension ruler 31 by 180°, thereby expanding the measuring length of the measuring ruler 3 and increasing the measuring range. After the extension ruler 31 has rotated completely, the limiting component on the rear side... The positioning component moves to the connection point of the extension ruler 31 and the measuring ruler 3. By rotating the knob 42, the knob 42 drives the threaded rod 41 to move, and the threaded rod 41 drives the abutment block 43 to move, so that one end of the abutment block 43 abuts against the connection point of the extension ruler 31 and the measuring ruler 3, and the other end of the hollow frame 4 abuts against the measuring ruler 3 or the extension ruler 31. The abutment block 43 works together to limit the connection point of the extension ruler 31 and the measuring ruler 3, thereby setting up an expandable measuring mechanism, increasing the measuring range of the measuring device, and improving the applicability of the measuring device. After the measurement is completed, the extended ruler 31 is folded and stored in reverse order.

[0034] When storing and carrying the device, loosen the wing nut 26, allowing it to move on the thread 25. This stops the wing nut 26 from pressing against the arc-shaped cylinder 24, creating a gap in the arc-shaped cylinder 24 from the surface of the rotating plate 22. This reduces the friction between the arc-shaped cylinder 26 and the abutment plate 23 and the rotating plate 22, allowing the measuring scale 3 at the rotating seat 2 to rotate slightly under pressure. Rotate multiple measuring scales 3 to the same side facing the length direction, then tighten the wing nut 26. This causes the arc-shaped cylinder 24 to press against the rotating plate 22, increasing the friction between the rotating plate 22 and the abutment plate 23. This prevents the rotating plate 22 from easily rotating under external force, thus reducing the overall... The space occupied is small, making it easy to store and carry. When measuring, the same method is used: the upper measuring ruler 3 is rotated to the direction corresponding to the height of the object to be measured, and the side measuring side is rotated to the direction corresponding to the width of the object to be measured. Thus, the length, width and height of the object to be measured are measured by the three measuring rulers 3 respectively. When measuring, the fixing base 1 is placed at the lower left front corner of the object to be measured, so that the back side of the baffle 11 abuts against the front side of the object to be measured, and the right side of the fixing base 1 abuts against the left side of the object to be measured. Thus, the length, width and height of the object to be measured are read according to the scale lines on the measuring ruler 3 and the extension ruler 31.
