Description

Technical Field

[0001] This utility model relates to the field of power engineering, and in particular to a power engineering surveying and ranging instrument. Background Technology

[0002] In power engineering surveying, rangefinders are crucial equipment. They accurately measure target distances, aid in trajectory calculations, and are essential for the smooth progress of engineering planning and line laying. Currently, there are various types of power engineering surveying rangefinders on the market. Based on their working principle, they mainly include laser rangefinders and infrared rangefinders (strictly speaking, infrared rangefinders also fall under the category of laser rangefinders; handheld laser rangefinders that emit a visible red dot are often called red laser rangefinders).

[0003] Existing power engineering surveying rangefinders typically employ a gear-rotating structure. By manually rotating a small gear, the large gear at the bottom of the rangefinder is driven to rotate, thus achieving the effect of adjusting the rangefinder's angle.

[0004] However, the gear rotation structure of existing power engineering surveying distance measuring instruments is susceptible to external influences during actual use, causing the distance measuring instrument to deviate. It is impossible to fix the angle after adjustment, which requires repeated manual adjustments and cannot guarantee the accuracy of the measurement data. Therefore, a new power engineering surveying distance measuring instrument is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a power engineering surveying distance measuring instrument, which aims to improve the problem that the existing technology cannot fix the angle after the angle is adjusted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power engineering surveying distance measuring instrument, comprising a distance measuring instrument body, a quick-release assembly at the bottom of the distance measuring instrument body, a fine-tuning assembly connected to the bottom of the quick-release assembly, the fine-tuning assembly comprising a support base, the support base being fixedly connected to the bottom of the quick-release assembly, a ring gear being fixedly connected to the bottom of the support base, a base being rotatably connected to the outer wall of the ring gear, a transmission gear meshing on the inner side of the outer wall of the ring gear, a knob being slidably connected through the inner wall of the transmission gear, a limit block being fixedly connected to the bottom of the knob, a follower ring being elastically connected to the bottom of the limit block through a limit spring, and a limit groove being formed at the bottom of the inner wall of the base.

[0007] As a further description of the above technical solution:

[0008] The quick-release assembly includes a locking block, which is fixedly connected to the bottom of the rangefinder body. A locking frame is engaged with the bottom of the locking block, and a bolt is threaded onto the inner wall of the left side of the locking frame. A locking groove is provided on the left side of the locking block.

[0009] As a further description of the above technical solution:

[0010] The top of the support base is fixedly connected to the bottom of the card frame.

[0011] As a further description of the above technical solution:

[0012] The knob is slidably connected to the inner wall of the top of the base, and the knob is slidably connected to the inner wall of the transmission gear.

[0013] As a further description of the above technical solution:

[0014] The limiting block is engaged with the bottom of the transmission gear and with the inner wall of the limiting groove.

[0015] As a further description of the above technical solution:

[0016] One end of the limiting spring is fixedly connected to the bottom of the limiting block, and the other end of the limiting spring is fixedly connected to the top of the follower ring.

[0017] As a further description of the above technical solution:

[0018] The follower ring is rotatably connected to the bottom inner wall of the base.

[0019] As a further description of the above technical solution:

[0020] The top of the card frame contacts the bottom of the rangefinder body, and the end of the bolt is engaged with the inner wall of the card slot.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a ring gear, a base, a transmission gear, a knob, and a limiting block, when it is necessary to adjust the angle of the rangefinder body, pull the knob upward to make the limiting block disengage from the limiting groove. Rotating the knob will drive the rangefinder body to rotate synchronously through the meshing of the transmission gear and the ring gear to achieve angle adjustment. After the adjustment is completed, release the knob, and the limiting spring will drive the limiting block to reset and lock into the limiting groove to lock the angle. This can achieve fine adjustment of the distance measuring angle and effectively avoid the problems of angle deviation and insufficient accuracy in traditional adjustment methods.

[0023] 2. In this utility model, a quick-release assembly consisting of a locking block, a locking frame, and a limiting bolt is set up to quickly connect the rangefinder body and the fine-tuning assembly. When the surveying work is completed and the equipment needs to be stored, or when the equipment malfunctions and needs maintenance, simply rotate the bolt counterclockwise to disengage it from the locking block's slot, and then slide the rangefinder body out to separate the locking block from the locking frame, thus completing the quick disassembly of the rangefinder body. The entire process does not require the use of multiple tools, the operation steps are simple, and the disassembly time can be significantly shortened. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a power engineering surveying rangefinder, comprising a rangefinder body 1. The rangefinder body 1 is an existing power engineering surveying rangefinder, used to measure target distances and perform trajectory calculations. A quick-release assembly 2 is provided at the bottom of the rangefinder body 1 for quickly removing the rangefinder body 1. A fine-tuning assembly 3 is connected to the bottom of the quick-release assembly 2 for fine-tuning the rotation of the rangefinder body 1. The quick-release assembly 2 includes a locking block 21, which is T-shaped and used to engage with a locking frame 22 to restrict the vertical movement of the rangefinder body 1. The locking block 21 is fixedly connected to the bottom of the rangefinder body 1. A frame 22 is attached, and a groove corresponding to the block 21 is opened on the top of the frame 22 to lock the block 21 and restrict its vertical movement. A bolt 23 is threadedly connected to the inner wall of the left side of the frame 22. The bolt 23 is used to lock the slot 24 to restrict the block 21 from sliding out laterally, which plays a limiting role. A slot 24 is opened on the left side of the block 21. The slot 24 is used to lock the bolt 23 to fix the block 21 to the frame 22. Alternatively, the bolt 23 can be used to disengage the block 21 from the slot 24 to quickly remove the rangefinder body 1, achieving the effect of convenient disassembly. The top of the frame 22 is in contact with the bottom of the rangefinder body 1, and the end of the bolt 23 is locked on the inner wall of the slot 24.

[0033] Reference Figure 2 , Figure 4 , Figure 5The fine-tuning component 3 includes a support base 31, which connects the ring gear 32 to the frame 22. When the ring gear 32 rotates, it drives the frame 22 and the top rangefinder body 1 to rotate. The support base 31 is fixedly connected to the bottom of the quick-release component 2. The ring gear 32 is fixedly connected to the bottom of the support base 31, providing rotational capability for the support base 31. It is driven to rotate by a transmission gear 34. A base 33 is rotatably connected to the outer wall of the ring gear 32. The base 33 can be mounted on a bracket or a fixed platform, providing support for the rangefinder body 1. For support, a transmission gear 34 meshes with the inner side of the outer wall of the ring gear 32. The transmission gear 34 drives the ring gear 32 to rotate, thereby driving the rangefinder body 1 to rotate. A knob 35 is slidably connected through the inner wall of the transmission gear 34. The knob 35 extends the limiting block 36 and facilitates external rotation of the limiting block 36, thereby driving the transmission gear 34 to rotate. The bottom of the knob 35 is fixedly connected to the limiting block 36. The limiting block 36 is square and is used to engage with the limiting groove 39 to restrict the rotation of the knob 35 and the transmission gear 34. The bottom of the limiting block 36... A follower ring 38 is elastically connected to the limiting spring 37. The follower ring 38 provides a rotatable fixing point for the limiting spring 37, preventing the limiting spring 37 from deforming or twisting when the knob 35 is rotated. A limiting groove 39 is formed at the bottom of the inner wall of the base 33. The limiting groove 39 is set as a multi-position groove in a circumferential array at the center of the limiting block 36, which is used to lock the limiting block 36 in multiple positions to change the angle of the rangefinder body 1. The top of the support base 31 is fixedly connected to the bottom of the frame 22. The knob 35 passes through and slides on the top inner wall of the base 33. The limiting block 36 is inserted through and slidably connected to the inner wall of the transmission gear 34, and is engaged with the bottom of the transmission gear 34 and the inner wall of the limiting groove 39. One end of the limiting spring 37 is fixedly connected to the bottom of the limiting block 36, and the other end of the limiting spring 37 is fixedly connected to the top of the follower ring 38. Through the opposing pressing force between the limiting spring 37 and the follower ring 38, the limiting block 36 is always engaged with the inner wall of the limiting groove 39 without being affected by external force. The follower ring 38 is rotatably connected to the bottom inner wall of the base 33.

[0034] Working Principle: When the angle of the rangefinder body 1 needs to be adjusted to accurately align with the target, precise adjustment is achieved through the fine-tuning component 3. First, by pulling the knob 35 upward, the knob 35 moves the square limiting block 36 fixedly connected to the bottom upward in sync, causing the limiting block 36 to disengage from the limiting groove 39 opened at the bottom of the inner wall of the base 33. At this time, the limiting block 36 is still engaged at the bottom of the transmission gear 34, maintaining the transmission connection. Simultaneously, the follower ring 38, which is elastically connected to the bottom of the limiting block 36 through the limiting spring 37, remains stationary because the follower ring 38 is rotated and connected to the bottom inner wall of the base 33. The limiting spring 37 is stretched, and after the limiting unlocking before angle adjustment is completed, the knob 35 is kept in the pulled-up state, and the knob 35 is rotated clockwise or counterclockwise. Because the knob 35 is slidably connected to the inner wall of the transmission gear 34, and the limiting block 36 is engaged at the bottom of the transmission gear 34, the rotation of the knob 35 will drive the transmission gear 34 to rotate synchronously. The transmission gear 34 meshes with the ring gear 32, and the top of the ring gear 32 is fixedly connected to the bottom of the support base 31. The support base 31 is also fixed to the clamping frame 22. Finally, the rotation of the ring gear 32 drives the support base 31, the clamping frame 22, and the rangefinder body 1 to rotate synchronously, realizing the fine adjustment of the measurement angle. When the angle of the rangefinder body 1 is adjusted to the appropriate position, the knob 35 is released. The stretched limit spring 37 generates a downward pulling force due to elastic reset, which drives the limit block 36 to move downward and re-clamp into the inner wall of the limit groove 39 of the base 33, thereby locking the current angle of the rangefinder body 1 and preventing angle deviation during the distance measurement process.

[0035] When the survey work is completed or the rangefinder body 1 needs to be removed separately, the bolt 23 on the left side of the frame 22 is rotated counterclockwise, so that the end of the bolt 23 gradually disengages from the slot 24 of the block 21, releasing the lateral restriction on the block 21. Then, the rangefinder body 1 is slid out backward, causing the bottom block 21 to disengage from the groove at the top of the frame 22, thus completing the separation of the rangefinder body 1 from the quick-release assembly 2, realizing the quick disassembly of the equipment, which is convenient for subsequent storage, carrying or maintenance.

[0036] 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.
