Description

Technical Field

[0001] The present application relates to the field of surveying and mapping tools, and in particular to a rangefinder adapter. Background Art

[0002] Distance measuring instruments have been widely used in building main body construction, interior decoration, bridge engineering, road construction and other aspects. Their characteristics are convenient, fast and accurate distance measurement. During the construction or acceptance process of a project, there will be a lot of data that needs to be measured, and the construction personnel need to measure it personally.

[0003] The current rangefinder adapter frame, as described in the patent with announcement number CN208418073U, includes a base, characterized in that a cone tip is installed at the center of the lower section of the base, the tip of the cone tip is set downward, and the cone tip is perpendicular to the base, a telescopic rod is vertically installed at the center of the upper end of the base, a mounting seat is installed at the top of the telescopic rod, and the mounting seat is parallel to the base, the telescopic rod includes a fixed sleeve, the upper end of the fixed sleeve is fixedly installed on the lower end of the mounting seat, and the fixed sleeve is perpendicular to the mounting seat, an insertion rod is inserted at the lower end of the interior of the fixed sleeve, the lower end of the insertion rod is fixedly installed on the base, and the insertion rod is perpendicular to the base, and a screw rod is also provided inside the fixed sleeve, and the top end of the screw rod is installed on the inner top end of the fixed sleeve through a first bearing.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the use of a cone tip inserted into the ground to fix the entire adapter frame makes it difficult to ensure that the cone tip is vertically inserted into the soil during use, which can easily cause the mounting base to tilt. Once the mounting base is tilted, it will cause the rangefinder subsequently placed on the mounting base to tilt, thereby affecting the measurement accuracy of the rangefinder. Therefore, in actual use, it is necessary to repeatedly debug the horizontality of the mounting base with the help of a level bubble, which is inefficient. Utility Model Content

[0008] By adopting the above technical solution, the gravity of the plumb cone is used vertically downward, so that the traction of the plumb rope can drive the rotating ball to move inside the ball hole until the support rod is adjusted to a vertical state, so that the mounting seat can be automatically adjusted to a horizontal state, and then the clamping bolt is tightened in the reverse direction until the clamping bolt is lowered and adjusted again to abut against the rotating ball, thereby limiting the rotating ball to maintain the vertical state of the support rod and the mounting seat to maintain a horizontal state, so as to reduce the probability of tilting of the rangefinder placed on the mounting seat later, thereby realizing rapid adjustment of the mounting seat to a horizontal state.

[0009] Optionally, the four bottom corners of the U-shaped plate are rotatably connected to rollers, and the interior of the U-shaped plate is symmetrically threadedly connected to a vertical plate.

[0015] Optionally, a placement groove is opened on one side of the top of the U-shaped plate, and the placement groove is adapted to the plumb cone.

[0016] By adopting the above technical solution, the placement groove is used to accommodate the plumb bob after the entire adapter frame is folded.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Please refer to Figure 1 The rangefinder adapter frame includes a U-shaped plate 1, and the four corners of the bottom of the U-shaped plate 1 are rotatably connected to rollers 2, and the setting of the rollers 2 facilitates the movement of the entire adapter frame. The inside of the U-shaped plate 1 is symmetrically threaded with a vertical plate 3, and the vertical plate 3 is set to limit the entire adapter frame after being rotated and implanted into the underground soil. The vertical plate 3 is symmetrically fixedly connected to one side of the top of the U-shaped plate 1, and a rotating block 4 is rotatably connected between two groups of vertical plates 3, and the vertical plate 3 is set to provide support for the rotating block 4.

[0032] Please refer to Figure 1The top of the rotating block 4 is fixedly connected with a telescopic rod, and the top of the telescopic rod is fixedly connected with a fixed plate 7. The telescopic rod includes an inner slide bar 5 fixedly connected with the top wall of the rotating block 4, and the outer side of the inner slide bar 5 is slidably connected with a hollow slide bar 6. Specifically, the cross-sections of the inner slide bar 5 and the hollow slide bar 6 are both rectangular. The top of the hollow slide bar 6 is fixedly connected with the fixed plate 7, and the outer wall of the hollow slide bar 6 is evenly fixedly connected with a plurality of right-angle plates 17, and each group of right-angle plates 17 is fixedly connected with the fixed plate 7. The setting of the right-angle plates 17 is used to further connect and fix the fixed plate 7 with the hollow slide bar 6, thereby improving the connection stability between the hollow slide bar 6 and the fixed plate 7.

[0033] Please refer to Figure 1 The interior of the hollow slide bar 6 is sleeved with a screw 10, which penetrates the fixed plate 7, is rotatably connected to the fixed plate 7, and is threadedly connected to the inner slide bar 5. The screw 10 is configured to be screwed along the interior of the inner slide bar 5 when rotating, thereby driving the fixed plate 7 to move up and down. The top of the fixed plate 7 is symmetrically fixedly connected with a mounting plate 11, and the top of the screw 10 is fixedly connected with a worm wheel 12. The interiors of the two sets of mounting plates 11 are rotatably connected with a worm 13, which is meshed with the worm wheel 12. The worm 13 is configured to drive the worm wheel 12 and the screw 10 to rotate when rotating, thereby realizing the rotation adjustment of the screw 10. At the same time, the self-locking property of the transmission of the worm 13 and the worm wheel 12 can reduce the probability of the screw 10 rotating on its own.

[0034] Please refer to Figure 1-2 A limiting mechanism is provided inside the side vertical board 3, and the limiting mechanism includes an insertion rod 21 that is slidably connected to the side vertical board 3. Four insertion holes 23 are provided in a circular array on the side of the rotating block 4 close to the vertical board 3. The insertion rod 21 is inserted into the inside of a group of insertion holes 23. The setting of the insertion rod 21 is used to limit the rotating block 4 after being inserted into the inside of the insertion hole 23. When the insertion rod 21 is pulled out from the inside of the insertion hole 23, the rotating block 4 can rotate freely, so that the rotating block 4 can adjust the inner slide rod 5 and the hollow slide rod 6 to the level when rotating, thereby realizing the folding of the entire adapter frame. The end of the insertion rod 21 away from the insertion hole 23 is fixedly connected to a connecting rope 22, and the end of the connecting rope 22 away from the insertion rod 21 is fixedly connected to the side vertical board 3. The setting of the connecting rope 22 is used to connect the insertion rod 21 to the vertical board 3, thereby reducing the probability of the insertion rod 21 being lost.

[0035] Please refer to Figure 1-3A ball hole 9 is provided on one side of the interior of the fixing plate 7, and a matching rotating ball 8 is movably connected inside the ball hole 9. The ball hole 9 is used to accommodate the rotating ball 8 so that the rotating ball 8 can move inside the ball hole 9. A support rod 14 is fixedly connected to the top of the rotating ball 8, and a mounting seat 24 is fixedly connected to the top of the support rod 14. The support rod 14 is used to provide support for the mounting seat 24, and the top of the mounting seat 24 is used to support the rangefinder. A plumb line 18 is fixedly connected to the middle position of the bottom of the rotating ball 8, and a plumb cone 19 is fixedly connected to the bottom of the plumb line 18. Specifically, the plumb line 18 is the same as the axis of the support rod 14. The plumb cone 19 is used to use its own gravity to pull the rotating ball 8 to move through the plumb line 18, so that the support rod 14 can be automatically adjusted to a vertical state, thereby keeping the mounting seat 24 horizontal.

[0036] Please refer to Figure 1-3 A placement groove 20 is provided on one side of the top of the U-shaped plate 1. The placement groove 20 is adapted to the plumb cone 19. The placement groove 20 is used to accommodate the plumb cone 19 after the entire adapter frame is folded. A clamping bolt 15 is threadedly connected to one side wall of the fixing plate 7. One end of the clamping bolt 15 close to the ball hole 9 abuts against the outer wall of the rotating ball 8. The clamping bolt 15 is used to limit the movement of the rotating ball 8 when it abuts against the rotating ball 8 during rotation. A knob 16 is fixedly connected to one end of the clamping bolt 15. The knob 16 is provided to facilitate the rotation and adjustment of the clamping bolt 15.

[0037] The implementation principle of this application is:

[0038] When in use, the adapter frame is pushed to the position to be detected, and then the two sets of vertical plates 3 are rotated to make the two sets of vertical plates 3 move downward until the two sets of vertical plates 3 are implanted in the soil at the position to be detected, and then the clamping bolt 15 is rotated until the clamping bolt 15 is adjusted to be out of contact with the outer wall of the rotating ball 8, and then the rotating ball 8 is pulled by the plumb rope 18 under the gravity of the plumb cone 19 to move, and the rotating ball 8 can drive the support rod 14 to move with it when it moves. Since the gravity of the plumb cone 19 is vertically downward, the traction of the plumb rope 18 can drive the rotating ball 8 moves inside the ball hole 9 until the support rod 14 is adjusted to a vertical state, and then the bolt 15 is tightened in the reverse direction until the tightening bolt 15 is lowered and adjusted again to abut against the rotating ball 8, thereby limiting the rotating ball 8 to maintain the vertical state of the support rod 14. Then the rangefinder for surveying and mapping can be placed on the top of the mounting seat 24 to measure the distance. Since the support rod 14 is in a vertical state, the mounting seat 24 fixed on the top of the support rod 14 can remain in a horizontal state, so that the level placed on the top of the mounting seat 24 can also remain horizontal.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
