Description

Technical Field

[0001] This utility model relates to the field of measurement and positioning technology, and in particular to a marine distance measuring instrument for rapid positioning. Background Technology

[0002] With the development of the maritime industry and the improvement of navigation safety standards, the demand for accurate distance measurement by ships in various complex sea conditions is increasing. Therefore, the industry needs a marine distance measuring instrument that can quickly locate, stably measure distances, and is easy to operate in dynamic environments. Publication number CN222336260U discloses a marine adjustable distance measuring instrument, relating to the field of measurement and positioning technology. This utility model discloses a marine adjustable distance measuring instrument, relating to the field of measurement and positioning technology, with the aim of providing a marine adjustable distance measuring instrument that can shorten positioning time and improve efficiency. Its key technical features include a ruler body, on which are engraved... The ruler has a central groove with two sliding plates slidably connected within it. These sliding plates move horizontally along the groove at the ruler's center. Grooves are formed on both sides of the sliding plates. The technical advantage is that by using the groove and sliding plates, the sliding plates are pushed horizontally within the groove by fixed sleeves. The distance between the two fixed sleeves is adjusted to match the distance between the sacrificial anode bolts. A marker is then placed inside the fixed sleeves, aligning its spacing with the bolts fixing the sacrificial anode, achieving rapid positioning. The sliding fixed sleeves allow for positioning at various distances. However, this distance meter requires manual adjustment in actual use. Manual adjustment is prone to errors due to external forces or ship movement, and the lack of an efficient adaptive adjustment mechanism affects the pointer's rapid alignment on the scale. The stability during positioning is low, increasing operational difficulty and reducing distance measurement efficiency. Measurement deviations are particularly prone to occur in dynamic environments, necessitating improvements. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a marine distance measuring instrument for rapid positioning, including a ruler body, the surface of which is provided with a scale, a handle fixedly installed on the side of the ruler body, a moving groove opened on the surface of the ruler body, a pressing block slidably connected inside the moving groove, a pointer fixedly installed on the side of the pressing block, a connecting plate fixedly installed on the lower surface of the pressing block, a sliding rod fixedly installed on the lower surface of the connecting plate, a circular plate fixedly installed at the bottom end of the sliding rod, a spring fixedly installed on the upper surface of the circular plate, a spring A fixedly installed on the lower surface of the circular plate, and a transverse moving block fixedly installed at one end of the spring A.

[0005] Preferably, the lower surface of the pointer is slidably connected to the surface of the ruler, one side of the connecting plate is slidably connected to the interior of the moving groove, and the surface of the transverse block is slidably connected to the interior of the moving groove. Here, the pointer always maintains smooth contact with the ruler during distance measurement, reducing measurement errors, improving accuracy, and ensuring stability during the distance measurement process, avoiding problems such as pointer deviation and instability.

[0006] Preferably, one end of the spring is fixedly connected to the lower surface of the movable plate, and the surface of the sliding rod is slidably connected to the inner side of the transverse block. Here, the spring can drive the pressing block and the mounting plate to rise, so that the position of the pressing block can be fixed to ensure the measurement accuracy of the pointer.

[0007] Preferably, the surface of the circular plate is slidably connected to the inner side of the transverse block, and the pressing blocks are symmetrically distributed inside the moving groove. Here, the sliding between the circular plate and the transverse block enhances the stability of positioning, and the symmetrically distributed pressing blocks allow the operator to measure the spacing.

[0008] Preferably, the ruler body has a storage groove on its side, and a secondary ruler is slidably connected inside the storage groove. A handle is fixedly installed on the side of the secondary ruler, and a circular groove is formed on the surface of the secondary ruler. A top block is slidably connected inside the circular groove, and a spring B is fixedly installed on the lower surface of the top block. Here, the design of the storage groove and the secondary ruler expands the distance measuring range, enabling the distance measuring instrument to adapt to more measurement needs, while improving the portability and flexibility of the device.

[0009] Preferably, one end of the top block is slidably connected to the interior of the storage groove, and one end of the spring B is fixedly connected to the interior of the circular groove. Here, the connection between the top block and the spring B ensures smooth operation of the auxiliary scale during use and storage, preventing jamming or loosening during extension and retraction, and improving the stability and service life of the distance measurement.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model incorporates a moving groove, a pressing block, a pointer, a connecting plate, a sliding rod, a circular plate, a spring, spring A, and a horizontal moving block. The pressing block and connecting plate slide within the moving groove under the force of the spring, while the sliding rod slides between the sliding block and the horizontal moving block. The circular plate slides within the horizontal moving block under the action of spring A, enabling rapid alignment and positioning of the pointer on the scale. When the pressing block is released, it and the connecting plate are stably fixed within the horizontal moving block under the force of the spring and spring A, ensuring rapid positioning of the aiming scale, improving the efficiency and accuracy of distance measurement, and optimizing the smoothness and stability of the measurement operation.

[0012] 2. This utility model incorporates a storage slot, a vernier scale, a handle, a circular groove, a top block, and a spring B. When the scale on the ruler is insufficient to meet the measurement length requirements, the vernier scale can be smoothly removed from the storage slot by pulling the handle, extending the measurement length and improving the ranging range and applicability. The top block, under the force of spring B, effectively prevents the vernier scale from accidentally slipping, ensuring stability and safety during the measurement process. The vernier scale can be pulled out and used separately, increasing the flexibility of the device and meeting the requirements for accurate measurement in multiple scenarios, overcoming the limitation of measurement length that affects the ranging effect.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1

[0022] Please see Figure 1-2This utility model provides a technical solution: a marine distance measuring instrument for rapid positioning, including a ruler body 1, the surface of the ruler body 1 is provided with scales 2, a handle 3 is fixedly installed on the side of the ruler body 1, a moving groove 4 is opened on the surface of the ruler body 1, a pressing block 5 is slidably connected inside the moving groove 4, a pointer 6 is fixedly installed on the side of the pressing block 5, a connecting plate 7 is fixedly installed on the lower surface of the pressing block 5, a sliding rod 8 is fixedly installed on the lower surface of the connecting plate 7, a circular plate 9 is fixedly installed at the bottom end of the sliding rod 8, and a spring 10 is fixedly installed on the upper surface of the circular plate 9. A spring A11 is fixedly installed on the lower surface of plate 9, and a transverse block 12 is fixedly installed on one end of spring A11. By setting a scale 2 on the surface of the ruler 1 and setting a moving groove 4, a pressing block 5, and a pointer 6, the positioning can be quick and accurate during the distance measurement process. Under the action of spring 10 and spring A11, the pressing block 5 and the connecting plate 7 can drive the pointer 6 to move within the moving groove 4, ensuring that the pointer 6 can quickly align with the scale 2 during distance measurement, reducing manual adjustment time and improving measurement efficiency, especially in dynamic ship environments. The system improves operational stability and reliability. The lower surface of pointer 6 is slidably connected to the surface of ruler 1; one side of connecting plate 7 is slidably connected to the interior of moving groove 4; the surface of transverse block 12 is slidably connected to the interior of moving groove 4; and pointer 6 is slidably connected to the surface of ruler 1, ensuring that pointer 6 adheres to ruler 1 during movement. The slidable connection between connecting plate 7 and the interior of moving groove 4 ensures the smoothness of pressing block 5 during movement. The slidable connection between transverse block 12 and the interior of moving groove 4 further enhances overall stability. Spring 10... One end of the sliding rod 8 is fixedly connected to the lower surface of the moving plate, and the surface of the sliding rod 8 is slidably connected to the inner side of the transverse block 12. The fixed connection between the spring 10 and the moving plate provides elastic rebound force, ensuring that the pressing block 5 can be fixed in the moving groove 4 after pressing and releasing, reducing human intervention. The surface of the circular plate 9 is slidably connected to the inner side of the transverse block 12. The pressing blocks 5 are symmetrically distributed inside the moving groove 4. The sliding connection between the circular plate 9 and the transverse block 12 allows the pressing block 5 and the pointer 6 to be flexibly adjusted according to actual measurement needs.

[0023] Example 2

[0024] Please see Figure 4The ruler body 1 has a storage slot 13 on its side, and a secondary ruler 14 is slidably connected inside the storage slot 13. A handle 15 is fixedly installed on the side of the secondary ruler 14, and a circular groove 16 is opened on the surface of the secondary ruler 14. A top block 17 is slidably connected inside the circular groove 16, and a spring B18 is fixedly installed on the lower surface of the top block 17. When the scale 2 of the ruler body 1 is insufficient to meet the measurement length requirements, the secondary ruler 14 can be smoothly removed from the storage slot 13 by pulling the handle 15, thereby extending the measurement length and improving the distance measurement range and applicability. One end of the top block 17 is slidably connected to the inside of the storage slot 13, and one end of the spring B18 is fixedly connected to the inside of the circular groove 16. Under the action of the spring B18, the top block 17 effectively prevents the secondary ruler 14 from accidentally slipping off. The secondary ruler 14 can be pulled out and used separately to meet the requirements of accurate measurement in multiple scenarios and overcome the impact of the distance measurement effect caused by the limitation of the measurement length.

[0025] Working principle: The distance measuring instrument measures distance through the scale 2 on the ruler 1. The handle 3 facilitates hand operation. During distance measurement, the pressing block 5 is located in the moving groove 4 on the surface of the ruler 1. By pressing the pressing block 5, the connecting plate 7 on its lower surface is connected to the sliding rod 8 under the action of the spring 10. The sliding rod 8 slides inside the transverse block 12. At the same time, the circular plate 9 slides inside the transverse block 12 under the action of the spring A11, realizing the smooth movement of the pressing block 5 and the rapid alignment of the pointer 6. When the pressing block 5 is released, the spring 10 and the spring A11 move away from the ground. The elastic force of 11 keeps the pressing block 5 and the connecting plate 7 stably fixed inside the horizontal moving block 12, ensuring the accurate positioning of the pointer 6 and the scale 2, and completing the distance measurement operation. When the scale 2 of the ruler body 1 is insufficient to meet the measurement length requirements, the auxiliary ruler 14 is pulled by the handle 15. The auxiliary ruler 14 is smoothly pulled out from the storage slot 13 of the ruler body 1. The top block 17 in the circular slot 16 slides under the action of the spring B18, ensuring that the auxiliary ruler 14 will not accidentally slip off during use. At the same time, it supports the independent use of the auxiliary ruler 14, further expanding the distance measurement range. Throughout the operation, the sliding connection of each component and the rebound force of the spring 10 ensure the stability, accuracy and efficiency of the distance measurement.
