Technical Field

[0001] The utility model relates to the technical field of distance measuring instruments, in particular to a distance measuring instrument for electric power engineering survey. Background Art

[0002] A rangefinder is a dead reckoning instrument used to measure target distance and perform dead reckoning. Rangefinders come in many forms, usually a long cylinder consisting of an objective lens, an eyepiece, and a rangefinder knob, used to measure target distance. Rangefinders are designed based on the principles of optics, acoustics, and electromagnetic waves. They are instruments used for distance measurement. Rangefinders are divided into two categories: one is a laser rangefinder; the other is an infrared rangefinder. Strictly speaking, an infrared rangefinder is also a type of laser rangefinder, but a handheld laser rangefinder has a red dot when it is fired, and is called a red laser rangefinder.

[0003] When using existing power engineering survey distance measuring instruments, the angle of use is usually fixed, and it is impossible to quickly measure the distance to any direction. The staff needs to lift and rotate the instrument together with the bracket to adjust the angle, which makes the device inconvenient to use.

[0004] Therefore, we propose an electric power engineering survey distance meter to solve the above problems. Utility Model Content

Example

[0026] See also Figure 1-6 A power engineering survey and distance meter comprises a fixed base 1 and a fixed frame 2 fixedly installed at the middle part of the top of the fixed base 1, a fixed shell 3 is provided above the top of the fixed frame 2, and a transmission shaft 4 is movably installed through the middle part of the top of the fixed shell 3, a rangefinder body 5 is fixedly installed on the upper end of the transmission shaft 4, and a transmission assembly 6 is installed on the output end of the transmission shaft 4, an adjustment assembly 7 is installed at the middle part of the top of the fixed base 1, and the angle of the rangefinder body 5 can be adjusted by setting the transmission assembly 6, and the height of the rangefinder body 5 can be adjusted by setting the adjustment assembly 7.

[0027] The transmission assembly 6 includes a driven bevel gear 61 fixedly sleeved on the output end of the transmission shaft 4 and an active bevel gear 62 meshed with the top of the driven bevel gear 61. A transmission rod 63 is fixedly installed at the middle part of the front side of the active bevel gear 62, and the front end of the transmission rod 63 is movable through and extends to the outside of the fixed shell 3. A rotating gear 64 is fixedly sleeved on the outside of the transmission rod 63 near the front end. A clamping gear 65 is meshed on the left side of the rotating gear 64, and a movable shaft 66 is fixedly installed through the middle part of the clamping gear 65. A pulling plate 67 is fixedly installed on the front end of the movable shaft 66, which can realize arbitrary adjustment of the angle of the rangefinder body 5, which is conducive to measuring distance in different directions.

[0028] A turntable 631 is fixedly mounted on the front end of the transmission rod 63 to facilitate driving the transmission rod 63 to rotate.

[0029] A sliding plate 661 is fixedly mounted on the rear side of the movable shaft 66 , and the rear side of the sliding plate 661 is slidably mounted on the outer wall of the fixed shell 3 to play a guiding and limiting role.

[0030] A pull handle 671 is fixedly installed in the middle of the front side of the pulling plate 67, and a side plate 672 is provided on the left side of the pulling plate 67. The rear side of the side plate 672 is fixedly installed on the fixed shell 3. A guide rod 673 is slidingly installed on the side plate 672 near the front side. The right end of the guide rod 673 is fixedly installed on the pulling plate 67. A return spring 674 is provided on the outer side of the guide rod 673. The two ends of the return spring 674 are respectively fixedly installed on the pulling plate 67 and the side plate 672, which is conducive to driving the pulling plate 67 to move to the left, thereby releasing the clamping position of the turntable 631.

[0031] The bottom of the fixed frame 2 is fixedly installed with limiting telescopic rods 21 near the four corners, and the lower ends of the limiting telescopic rods 21 are fixedly installed on the fixed seat 1, which plays a guiding and limiting role when the fixed frame 2 moves, and has high stability.

[0032] In this embodiment, when in use, the distance measurement operation can be achieved by setting the rangefinder body 5, and its angle can also be adjusted during the distance measurement process. By pulling the handle 671 to the left, the pulling plate 67 can be driven to move to the left. When the pulling plate 67 moves to the left, it squeezes the reset spring 674. At the same time, when the pulling plate 67 moves to the left, it also drives the engaging gear 65 to move to the left through the movable shaft 66, so that it is not engaged with the rotating gear 64. At this time, the engaging of the rotating gear 64 can be released, and then the turntable 631 can be rotated to drive the transmission rod 63 to rotate, and the transmission rod 63 rotates. When the driving bevel gear 62 rotates, the driving bevel gear 62 rotates, and when the driven bevel gear 61 rotates, the transmission shaft 4 rotates, which can drive the rangefinder body 5 to rotate to adjust its angle. After adjustment, the rotation of the turntable 631 can be stopped, and the pulled handle 671 can be released at the same time, so that the pulling plate 67 is restored under the action of the rebound force of the reset spring 674, so that the engaging gear 65 can continue to be engaged with the rotating gear 64, thereby playing a positioning role and preventing the turntable 631 from rotating due to accidental collision. Example

[0033] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2-3 and Figure 6 The adjustment component 7 includes a servo motor 71 fixedly mounted at the middle of the top of the fixing base 1 and a threaded rod 72 fixedly mounted at the output end of the servo motor 71. A threaded sleeve 73 is threadedly mounted on the outer side of the threaded rod 72 near the lower end, and L-shaped rods 74 are fixedly mounted on the front and rear sides of the threaded sleeve 73. The upper ends of the L-shaped rods 74 are fixedly mounted on the fixed shell 3, so that the height of the rangefinder body 5 can be adjusted arbitrarily.

[0034] A flat plate 721 is movably mounted on the upper end of the threaded rod 72 , and both left and right sides of the flat plate 721 are fixedly mounted on the inner wall of the inner cavity of the fixed frame 2 , playing a role in supporting the threaded rod 72 when it rotates.

[0035] In this embodiment, the height of the rangefinder body 5 can also be adjusted according to actual needs. The operation of the servo motor 71 can drive the threaded rod 72 to rotate. When the threaded rod 72 rotates, it drives the threaded sleeve 73 to move upward. When the threaded sleeve 73 moves upward, it drives the fixed shell 3 to move upward through the L-shaped rod 74, thereby achieving the height adjustment of the rangefinder body 5.

[0036] Working principle: When in use, the distance measurement operation can be achieved through the setting of the rangefinder body 5, and its angle can also be adjusted during the distance measurement process. By pulling the handle 671 to the left, the pulling plate 67 can be driven to move to the left. When the pulling plate 67 moves to the left, it will squeeze the reset spring 674. At the same time, when the pulling plate 67 moves to the left, it will also drive the engaging gear 65 to move to the left through the movable shaft 66, so that it will not engage with the rotating gear 64. At this time, the engaging of the rotating gear 64 can be released, and then the turntable 631 can be rotated to drive the transmission rod 63 to rotate. When the transmission rod 63 rotates, it will drive the active bevel gear 62 to rotate. When the active bevel gear 62 rotates, it will drive the driven bevel gear 61 to rotate. When the driven bevel gear 61 rotates, it will drive the transmission shaft 4 Rotation can drive the rangefinder body 5 to rotate and adjust its angle. After adjustment, the rotation of the turntable 631 can be stopped, and the pulled handle 671 can be released, so that the pulling plate 67 is restored under the action of the rebound force of the reset spring 674, so that the engaging gear 65 can continue to be engaged with the rotating gear 64, playing a positioning role, and preventing the turntable 631 from accidentally hitting and rotating. In addition, the height of the rangefinder body 5 can be adjusted according to actual needs. The operation of the servo motor 71 can drive the threaded rod 72 to rotate. When the threaded rod 72 rotates, it drives the threaded sleeve 73 to move upward. When the threaded sleeve 73 moves upward, it drives the fixed shell 3 to move upward through the L-shaped rod 74, thereby achieving the height adjustment of the rangefinder body 5.
