Description

Technical Field

[0001] This utility model relates to the field of optical theodolite technology, and in particular to an optical theodolite for engineering surveying. Background Technology

[0002] With the continuous development of engineering surveying technology, optical theodolites, as high-precision measuring instruments, play a crucial role in construction, surveying, and other engineering fields. Through their sophisticated optical systems and mechanical structures, optical theodolites can accurately measure angles and positions, playing a decisive role in the accuracy of project implementation and construction processes. However, optical theodolites often need to be used in harsh environments, such as construction sites and open fields, where vibrations, impacts, dust, and moisture can all affect the instrument's performance and measurement accuracy. Therefore, ensuring the safety and reliability of optical theodolites during transportation, storage, and use has become an urgent problem to be solved in the field of engineering surveying.

[0003] In existing technologies, optical theodolites are typically protected by metal casings, plastic frames, or similar materials. The casing provides basic protection for the internal components, preventing direct damage from impacts, dust, and moisture encountered during daily use. Simultaneously, the outer frame is usually secured with screws to ensure the stability of the optical theodolite. Traditional designs primarily focus on physical barriers, but there remains a significant gap in addressing vibrations or the dispersion of localized pressure caused by external impacts. This means that even with external protection, the instrument's internal precision components are still susceptible to impact forces, potentially leading to decreased measurement accuracy or damage to internal components.

[0004] When subjected to external impacts or vibrations, the precision components of existing optical theodolites often struggle to effectively withstand these forces. Although the outer casing and frame offer some protection, their structure may not be sufficient to effectively disperse the impact force, leading to excessive vibration of the internal precision components and increasing the risk of damage. Especially during transportation or sudden collisions, the stability and measurement accuracy of optical theodolites can be severely affected. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an optical theodolite for engineering measurement, which aims to improve the problem that the precision components of existing optical theodolites are often unable to effectively resist the influence of external forces when subjected to external impacts or vibrations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical theodolite for engineering surveying, comprising an outer frame, a fixed plate fixedly connected to the outer wall of the outer frame, a rotating shaft rotatably connected to the inner side of the outer frame, a storage base fixedly connected to one end of the rotating shaft, an optical theodolite body fixedly connected to the inner side of the storage base, a fixed block fixedly connected to the outer wall of the fixed plate, a telescopic rod fixedly connected to the inner wall of the fixed block, a buffer spring sleeved on the outer wall of the telescopic rod, a spring sheet slidably connected to the inner wall of the fixed block, both ends of the spring sheet slidably connected to the inner wall of the fixed block, a baffle plate abutting the outer wall of the spring sheet, and a buffer assembly provided on the outer wall of the spring sheet;

[0007] The buffer assembly includes a second telescopic rod, one end of which is fixedly connected to the outer wall of the spring sheet, and a second buffer spring is sleeved on the outer wall of the second telescopic rod.

[0009] Furthermore, the propulsion assembly includes a slide rod, the outer wall of which is slidably connected to the interior of the outer frame, and a telescopic spring is sleeved on the outer wall of the slide rod.

[0010] Furthermore, one end of the telescopic spring is fixedly connected to the outer wall of the sealing plate, and the other end of the telescopic spring is fixedly connected to the inside of the outer frame.

[0011] Furthermore, one end of the second buffer spring is fixedly connected to the outer wall of the spring sheet, and the other end of the second buffer spring is fixedly connected to the outer wall of the fixed plate.

[0012] Furthermore, one end of the buffer spring is fixedly connected to the inner wall of the fixed block, and the other end of the buffer spring is fixedly connected to a spring sheet.

[0013] Furthermore, the optical theodolite body is disposed inside the outer frame, and the outer frame is used to protect the optical theodolite body.

[0014] Furthermore, the outer wall of the baffle is slidably connected to the outer wall of the fixed plate, and the fixed plate is used to limit the position of the baffle.

[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] Reference Figure 1 - Figure 3This utility model provides an embodiment of an optical theodolite for engineering surveying, comprising an outer frame 1 to further resist external impacts. A fixing plate 7 is fixedly connected to the outer wall of the outer frame 1, providing initial protection for the instrument through a closed structure when the optical theodolite body 14 is not in use. A rotating shaft 5 is rotatably connected inside the outer frame 1, with a fixed base 4 at one end of the shaft 5. The optical theodolite body 14 is fixedly connected inside the base 4. A fixing block 8 is fixedly connected to the outer wall of the fixing plate 7, restricting the movement trajectory of the spring sheet 11 and ensuring stable sliding during buffering. The device is designed to effectively transmit external force. A telescopic rod 9 is fixedly connected to the inner wall of the fixed block 8. A buffer spring 10 is sleeved on the outer wall of the telescopic rod 9. A spring plate 11 is slidably connected to the inner wall of the fixed block 8. When subjected to pressure from the fixed plate 7, the spring plate 11 deforms, which in turn drives the buffer spring 10 and the buffer spring 13 to contract. Both ends of the spring plate 11 are slidably connected to the inner wall of the fixed block 8. A baffle 6 is attached to the outer wall of the spring plate 11. When subjected to external force, the baffle 6 slides inside the fixed plate 7, so that the pressure is evenly transmitted to the spring plate 11, thereby improving the buffering effect. A buffer assembly is provided on the outer wall of the spring plate 11.

[0026] The buffer assembly includes a telescopic rod 12, one end of which is fixedly connected to the outer wall of the spring plate 11. A buffer spring 13 is sleeved on the outer wall of the telescopic rod 12, which contracts simultaneously when impacted to absorb external force and reduce damage to the precision parts of the instrument.

[0027] Specifically, the instrument is protected in all aspects by closing the fixed plate 7, reinforcing the outer frame 1, and sealing the plate 15. When subjected to external impact, the baffle 6 slides inside the fixed plate 7, causing the fixed plate 7 to apply pressure to the spring plate 11. The spring plate 11 deforms accordingly and further drives the second buffer spring 13 to contract. At the same time, due to the deformation of the spring plate 11, its two ends slide inside the fixed block 8, thereby applying pressure to the first buffer spring 10. The first buffer spring 10 and the second buffer spring 13 contract synchronously, which can effectively disperse the impact of external force. When the optical theodolite body 14 is subjected to severe vibration or impact, the vibration amplitude of the internal precision components is greatly reduced, thereby reducing the possibility of damage. In addition, it can quickly return to its original state after the external force disappears, ensuring the long-term stability of the instrument and improving the safety and durability of the equipment during transportation and use.

[0028] Reference Figure 1 and Figure 4The upper surface of the outer frame 1 is fixedly connected with a buckle 2 to secure the outer frame 1 and keep it closed during transportation to prevent the instrument from loosening due to vibration. A handle 3 is fixedly connected to the upper surface of the outer frame 1 for easy carrying of the optical theodolite body 14, allowing operators to easily move the equipment. A sealing plate 15 is slidably connected to the top of the outer frame 1. When the outer frame 1 is closed, the sealing plates 15 on both sides fit together, achieving a preliminary seal. Limiting blocks 18 are fixedly connected to both sides of the outer wall of the sealing plate 15. A propulsion assembly, including a slide rod 16, is provided inside the outer frame 1. The outer wall of the slide rod 16 is slidably connected to the inside of the outer frame 1, and a telescopic spring 17 is sleeved on the outer wall of the slide rod 16 to keep the sealing plate 15 always in place. To ensure effective dust and water resistance, the following components are installed: one end of the telescopic spring 17 is fixedly connected to the outer wall of the sealing plate 15, and the other end of the telescopic spring 17 is fixedly connected to the inside of the outer frame 1; one end of the second buffer spring 13 is fixedly connected to the outer wall of the spring sheet 11, and the other end of the second buffer spring 13 is fixedly connected to the outer wall of the fixing plate 7; one end of the first buffer spring 10 is fixedly connected to the inner wall of the fixing block 8, and the other end of the first buffer spring 10 is fixedly connected to the spring sheet 11; the optical theodolite body 14 is located inside the outer frame 1, and the outer frame 1 is used to protect the optical theodolite body 14; the outer wall of the baffle 6 is slidably connected to the outer wall of the fixing plate 7, and the fixing plate 7 is used to limit the position of the baffle 6.

[0029] Specifically, during transportation, the user can close the outer frame 1, causing the sealing plates 15 on both sides to fit together. With the help of the elastic force of the telescopic spring 17, the sealing plates 15 are kept in a tight fit, thus forming a stable sealing barrier. This effectively prevents external rainwater, dust, or other pollutants from entering the interior of the optical theodolite body 14, ensuring that the optical components are not affected by moisture or dust accumulation, thus maintaining measurement accuracy. At the same time, it reduces maintenance frequency and repair costs, and extends the service life of the instrument. This not only improves the reliability of the optical theodolite body 14 but also greatly enhances its adaptability in complex engineering measurement scenarios, providing a solid guarantee for high-precision measurement tasks.

[0030] Working principle: When not in use, the optical theodolite 14 for engineering surveying can be protected by closing the two fixed plates 7, and then the outer frame 1 strengthens the protection. When subjected to external force, the baffle 6 will slide inside the fixed plate 7, thereby applying pressure to the spring plate 11 through the fixed plate 7, causing the spring plate 11 to deform, which in turn causes the second buffer spring 13 to contract. At the same time, through the deformation of the spring plate 11, its two ends will slide inside the fixed block 8, thereby applying pressure to the first buffer spring 10, which in turn causes the first buffer spring 10 and the second buffer spring 13 to contract simultaneously. The thrust generated by the contraction of the first buffer spring 10 and the second buffer spring 13 buffers the external force, thus achieving the effect of protecting the broadcasting and television equipment.

[0031] In addition, when transporting the optical theodolite body 14, the outer frame 1 can be closed and then fixed by the buckle 2. Finally, the handle 3 is used to carry the outer frame 1 and the internal optical theodolite body 14 respectively. During this process, the closure between the two outer frames 1 will also cause the sealing plates 15 on both sides to stick together, achieving a preliminary seal. The extension spring 17 can push the sealing plate 15 to stick tightly, achieving a stable seal and preventing external rain or dust from affecting the internal optical theodolite body 14.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
