Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of range finder positioning mechanism, in particular to a multi-directional adjustment safety protection range finder for communication construction. BACKGROUND

[0002] The telescope range finder, also known as a long-distance laser range finder, generally uses the pulse method to measure distance and is widely used in communication construction, power line measurement, construction survey design, and base station establishment. In the process of pulse range finding, the laser emitted by the range finder is reflected by the measured object and then received by the range finder, which records the time of the laser round trip. Half of the product of the speed of light and the round trip time is the distance between the range finder and the measured object.

[0003] In the process of using the range finder, it is sometimes necessary to measure different directions and angles of the same place. However, the current range finder usually needs to be manually moved to different directions during measurement, which is not only difficult to operate but also difficult to accurately adjust the position.

[0004] Moreover, the existing range finder direction changing positioning mechanism is inconvenient to store after use and is prone to damage when exposed for a long time. In addition, the steps of installing, positioning, and disassembling the range finder direction changing positioning mechanism are relatively complicated, and the positioning effect is poor.

[0005] In the invention patent with the patent number 201710724767, a range finder direction changing positioning device for easy adjustment is disclosed, which effectively solves the problems of inconvenient direction adjustment and time-consuming and laborious operation of the range finder during use. The technical solution includes a bottom plate with intermeshing bevel gears, a second bevel gear connected to a spherical seat, a spherical body installed inside the spherical seat, a control lever fixed to the right side of the spherical body, and a control device composed of the spherical body and the control lever. Above the first bevel gear is a concave bracket, which penetrates a rotatable adjusting rod, and the adjusting rod has a gear installed at one end, which engages with a rack. The control lever has a sleeve installed at the right end, and the sleeve is connected to two turbines on the front and rear sides, respectively. The two turbines are symmetrically arranged on the bottom plate, and the control lever can drive the two turbines to rotate synchronously. The turbine is engaged with a worm on the left side, and the upper end of the worm penetrates an activity disc. The upper end of the worm is screw-connected with the activity disc. The present application has a clever structure and is easy to operate.

[0006] For this related technology patent, the inventor thinks that: when adjusting the elevation angle of the range finder, the device is pushed to rotate up and down in the guide groove, thereby driving the adjusting rod to rotate to adjust the elevation angle of the range finder. When manually pushing the control lever to rotate up and down, it is difficult to control the force, resulting in low accuracy of the range finder elevation angle adjustment. After use, it is not convenient to store the range finder, and long-term exposure to the outside may cause damage.

[0007] In the utility model patent with the patent number 202220127519, a range finder direction changing positioning device convenient to adjust is disclosed, which comprises a box body and an adjusting and positioning assembly. The adjusting and positioning assembly comprises a sleeve column, a spring one, a sliding column, a fixed column, a limiting rod, a guide column, a guide block, a cross plate, a range finder, a positioning column and a spring two. The utility model belongs to the technical field of direction changing positioning, and specifically relates to a range finder which can be stored when not in use and taken out from the box body quickly when in use. The range finder can be adjusted at different angles and quickly positioned after adjustment. The movement distance of the sliding column can be limited, so that the positioning effect is improved. The device has a simple overall structure, improves the protection effect of the range finder, and has improved practicability.

[0008] For this related technology patent, the inventor thinks that: although the device can store the range finder, it limits the rotation angle of the cross plate, so that the range finder cannot be rotated to be parallel to the opening of the box body, and manual operation is required during storage, which is troublesome.

[0009] Therefore, the present application provides a multi-directional adjustment safety protection range finder for communication construction to solve the above problems. SUMMARY

Figures 1 to 5 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0035] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0036] Example 1, by Figures 1-2 The present invention includes a laser rangefinder 1 and a housing 2. The laser rangefinder 1 is a telescope-type laser rangefinder with an objective lens at the front end, an eyepiece at the rear end, and a display screen and a distance measurement button at the top. The distance measurement button is used for measuring distance and powering on the laser rangefinder 1, and the display screen is used for distance reading. The inner side of the housing 2 is a cavity, and a circular hole is provided in the middle of the upper end. To facilitate the adjustment of the horizontal circumferential angle and the pitch angle, a protective box 3 is provided above the circular hole. The inner side of the protective box 3 is a cavity, and the upper end has a disc structure that is connected to the large diameter of the circular hole. The device is small and consistent, with a ranging hole at the front end that corresponds to the objective lens of the laser rangefinder 1. The laser rangefinder 1 is detachably installed in the protective box 3. Crank mechanisms 4 are rotatably installed on the left and right sides of the lower end of the protective box 3. Each crank mechanism 4 includes a first crank rotatably installed on the front and rear sides of the lower end of the protective box 3. A second crank is rotatably installed between the lower ends of the two first cranks. A rotating rod 5 is fixedly connected between the middle of the two second cranks. An elevation gear 6 is coaxially fixedly installed in the middle of the rotating rod 5. An auxiliary frame 7 is rotatably installed on the upper side of the rotating rod 5. The auxiliary frame 7 includes a horizontal plate and connecting blocks fixedly connected to the left and right sides of the lower end of the horizontal plate. Two connecting blocks are rotatably installed on the left and right sides of the rotating rod 5, respectively. A rotating adjustment plate 8 is provided at the lower end of the auxiliary frame 7. A lifting base plate 9 is fixedly connected to the lower end of the rotating adjustment plate 8 and slidably installed in the housing 2. A circular groove is provided at the upper end of the rotating adjustment plate 8. A roller is rotatably installed and slidably installed in the circular groove at the lower end of each connecting block. A drive cone is provided on the upper side of the lifting base plate 9. Gear 10, the upper left end of the drive bevel gear 10 is meshed with a rotating adjustment bevel gear 11, an L-shaped connecting plate 13 is rotatably mounted on the rotating adjustment bevel gear 11, the right end of the L-shaped connecting plate 13 is rotatably connected to the drive bevel gear 10, the upper end of the rotating adjustment bevel gear 11 is fixedly connected to and slidably mounted on the horizontal plate of the auxiliary frame 7 with an elevation angle rack 12, the elevation angle rack 12 is meshed with an elevation angle gear 6, and the rear end of the elevation angle rack 12 is fixedly connected to two limit blocks located on the upper and lower sides of the lifting base plate 9 respectively;

[0037] When it is necessary to adjust the horizontal circumferential angle of the rangefinder, the operator rotates the drive bevel gear 10, which meshes with the adjustment bevel gear 11 to rotate, and at the same time drives the pitch rack 12 to rotate, which in turn drives the auxiliary frame 7 to rotate. At this time, each roller slides in the circular groove. The auxiliary frame 7 drives the crank mechanism 4, the protective box 3 and the laser rangefinder 1 to move horizontally in a circular motion through the rotating rod 5, thereby achieving the purpose of conveniently adjusting the horizontal circumferential angle of the rangefinder.

[0038] When the pitch angle of the rangefinder needs to be adjusted, the operator slides the drive bevel gear 10 up or down, and through the L-shaped connecting plate 13, drives the rotating adjustment bevel gear 11 to slide up or down. At the same time, the pitch angle rack 12 meshes with the pitch angle gear 6 and rotates, which in turn drives the rotating rod 5 and each second crank to rotate. Through each first crank, the protective box 3 and the laser rangefinder 1 are driven to achieve the purpose of pitch angle adjustment. When the pitch angle rack 12 slides up, the front end of the protective box 3 and the laser rangefinder 1 is tilted downwards for adjustment. When the pitch angle rack 12 slides down, the front end of the protective box 3 and the laser rangefinder 1 is tilted upwards for adjustment.

[0039] Example 2, based on Example 1, is... Figure 3 The upper end of the lifting base plate 9 is provided with a horizontal sliding groove. An adjusting frame 14 is slidably installed in the horizontal sliding groove. A strip-shaped hole is passed through the adjusting frame 14. A vertical sliding groove is provided at the rear end of the adjusting frame 14. A lifting adjusting block 15 is slidably installed in the vertical sliding groove. A rotating adjusting rod 16, which passes through the strip-shaped hole, is rotatably installed in the lifting adjusting block 15. A rotating adjusting knob is coaxially fixedly installed on the right end of the rotating adjusting rod 16. A circular sliding hole is coaxially provided on the left end of the rotating adjusting rod 16. A circular sliding hole is coaxially fixedly connected to the right end of the drive bevel gear 10. A drive bevel gear rod 17 is fitted into a circular sliding hole. A keyway is provided on the upper inner side of the circular sliding hole. A bar key is fixedly connected to the upper end of the drive bevel gear rod 17 and is slidably installed in the keyway. A lifting screw 18 is rotatably installed on the rear side of the adjusting frame 14 and threadedly connected to the lifting adjusting block 15. A reversing bevel gear 19 is coaxially fixedly installed on the upper end of the lifting screw 18. A lifting bevel gear 20 that meshes with the reversing bevel gear 19 is rotatably installed on the upper end of the adjusting frame 14. A pitch adjustment knob is coaxially fixedly connected to the right end of the lifting bevel gear 20.

[0040] When it is necessary to adjust the horizontal circumferential angle of the rangefinder, the operator rotates the adjustment knob, which simultaneously drives the adjustment rod 16 to rotate. The keyway and bar key drive the drive bevel gear rod 17 to rotate coaxially, thereby driving the drive bevel gear 10 to mesh with the adjustment bevel gear 11 to rotate, thus adjusting the horizontal circumferential angle of the rangefinder.

[0041] When the angle of the range finder needs to be adjusted, the worker rotates the tilt adjusting knob, which drives the lifting bevel gear 20 to rotate, and then drives the lifting screw 18 to slide up or down, thereby driving the rotating adjusting rod 16 and the driving bevel gear rod 17 to slide up or down along the strip-shaped hole, so as to adjust the angle of the range finder.

[0042] In example three, on the basis of example two, the inner bottom of the box body 2 is fixedly provided with a vertical plate 21 penetrating through the lifting bottom plate 9, the vertical plate 21 is provided with an extension slide 22, the lower side of the extension slide 22 is a vertical slide, the upper side of the vertical slide is communicated with an inclined slide inclined to the right upper side, the front end of the adjusting frame 14 is fixedly connected with an extension slide block 23 slidably installed in the extension slide 22, and the right end of the box body 2 is provided with an adjusting hole 24. Figures 2-3

[0043] After the distance measurement is completed, the laser range finder 1 can be retracted into the box body 2 to avoid damage caused by long-term exposure to the outside. At this time, the worker slides the lifting bottom plate 9 downward, which drives the laser range finder 1, the protection box 3 and the adjusting frame 14 to slide downward. Since the extension slide block 23 is slidably installed in the extension slide 22, when the extension slide block 23 slides in the inclined slide, the extension slide block 23 drives the adjusting frame 14 to slide leftward on the lifting bottom plate 9, and then drives the rotating adjusting rod 16, the rotating adjusting knob and the tilt adjusting knob to slide leftward synchronously. In this process, the key groove slides leftward along the strip-shaped key, and the rotating adjusting knob and the tilt adjusting knob are retracted into the box body 2 through the adjusting hole 24. When the extension slide block 23 slides to the vertical slide, the rotating adjusting knob and the tilt adjusting knob are completely retracted and vertically move downward with the lifting bottom plate 9 until the extension slide block 23 slides to the lowermost end of the extension slide 22. At this time, the disc structure at the upper end of the protection box 3 coincides with the circular hole at the upper side of the box body 2, the upper end face of the disc structure is flush with the upper end face of the box body 2, and the protection box 3 and the laser range finder 1 are completely retracted into the box body 2.

Figures 4-5 ​​The rear end of the protection box 3 is provided with a box opening 26, and the left and right sides of the bottom end of the protection box 3 are respectively provided with slide plate grooves, each of which is respectively provided with a positioning slide plate 27 slidingly installed on the left and right sides, and each of the positioning slide plates 27 is respectively provided with a slanting slide hole 28, and the two slanting slide holes 28 are symmetrical to each other, and the left and right sides of the lower end of the protection box 3 are respectively provided with a positioning slide rod 29 slidingly installed on the front and back sides, and the front side of the upper end of each positioning slide rod 29 is respectively fixedly connected with a positioning slide block 30 slidingly installed in each slanting slide hole 28, and the upper ends of the two positioning slide plates 27 are respectively fixedly installed with arc-shaped positioning plates 31 located at the left and right ends of the laser range finder 1, and the mutually close ends of the two arc-shaped positioning plates 31 are respectively fixedly installed with rubber pads, and the mutually far ends of the two arc-shaped positioning plates 31 are respectively fixedly connected with a plurality of positioning springs 32, and the other ends of each of the positioning springs 32 are fixedly connected with the side wall of the protection box 3.

[0047] The worker slides each positioning slide rod 29 backward, and simultaneously drives each positioning slide block 30 to slide backward, since the positioning slide block 30 is slidingly installed in the slanting slide hole 28, at this time, the positioning slide block 30 slides backward in the slanting slide hole 28, and drives the two positioning slide plates 27 to move away from each other, and the two arc-shaped positioning plates 31 release the positioning of the laser range finder 1, and each positioning spring 32 is compressed, and then the laser range finder 1 can be taken out from the box opening 26.

[0048] When the laser range finder 1 is installed, the worker places the laser range finder 1 between the two arc-shaped positioning plates 31, and makes the front end face of the laser range finder 1 abut against the front end face of the protection box 3, and then releases the positioning slide rod 29, and drives the two arc-shaped positioning plates 31 to reposition the laser range finder 1 through each positioning spring 32.

Figure 5As shown, at this time, since each positioning spring 32 is in a compressed state, the box cover 34 is positioned at the rear end face of the protection box 3, so that it is not necessary to manually continuously hold the positioning slide rod 29, which facilitates the disassembly and installation of the staff. After the laser range finder 1 is placed into the protection box 3, the box cover 34 is turned back and slid into the positioning slide groove 33, and the arc-shaped positioning plate 31 repositions the laser range finder 1.
