Description

Technical Field

[0001] The utility model relates to the technical field of laser distance measuring equipment, in particular to a laser distance measuring instrument capable of converting measuring angles for construction engineering. Background Art

[0002] Laser rangefinder is an instrument that uses laser to accurately measure the distance to a target. It emits a laser beam to the target and receives the laser beam reflected by the target. It measures the time from the laser beam emission to the reception and calculates the distance from the observer to the target. Laser rangefinder is widely used in the field of construction engineering.

[0003] During use, the laser rangefinder needs to adjust the measuring angle in multiple directions to ensure the accuracy of the measured data. During use, the existing laser rangefinder basically adjusts the measuring angle of the laser rangefinder by adjusting the supporting angle of the supporting frame. However, since there are multiple groups of supporting rods on the supporting frame, it is necessary to adjust different supporting rods separately, which is cumbersome to operate and has low reliability, affecting the measurement accuracy of the laser rangefinder. At the same time, in the prior art, a screw is usually used to connect the laser rangefinder to the supporting frame, which makes it inconvenient to disassemble and install the laser rangefinder, affecting the construction progress. Utility Model Content

[0004] In view of the above-mentioned technical problems, the utility model provides a laser rangefinder with convertible measuring angles for construction engineering.

[0005] The technical solution of the utility model is: a laser rangefinder capable of converting measuring angles for construction engineering, comprising a mounting seat, a first adjustment component, a second adjustment component and a laser rangefinder body;

[0006] The first adjustment assembly includes a rotating seat arranged on the mounting seat, a support frame clamped on the rotating seat, and an adjustment worm rotatably clamped on the rotating seat;

[0007] The second adjustment assembly includes a mounting shaft clamped inside the support frame, a first gear ring sleeved on the mounting shaft, a first gear box disposed on the outer wall of the support frame, a first adjustment rod clamped on the first gear box, and a first gear sleeved on the first adjustment rod and meshed with the first gear ring;

[0008] The laser rangefinder body is fixedly connected to the mounting shaft.

[0009] Furthermore, a mounting groove is provided on the bottom surface of the mounting seat, and two clamping seats are slidably connected inside the mounting groove, and the ends of the two clamping seats that are far away from each other are both provided with a first compression spring that abuts against the inner wall of the mounting groove; the sides of the two clamping seats that are close to each other are both movably connected with a plurality of follower rods, and the inside of the clamping seat is provided with a second compression spring that abuts against the follower rod at the corresponding position;

[0010] Description: When in use, the mounting seat is clamped on the external bracket through the mounting groove. The two clamping seats are close to each other under the action of the first compression spring and clamp and fix the external bracket; at the same time, each follower rod can be adaptively adjusted according to the shape of the external bracket, which improves the convenience and reliability of the mounting seat during installation and removal.

[0011] Furthermore, locking strips penetrating the mounting seat are provided on both sides of the lower bottom surface of the rotating seat, and the lower bottom surfaces of the two locking strips are provided with teeth that can be movably engaged with the clamping seat; guide rods are provided on both sides of the upper end surface of the mounting seat, and sliding sleeves corresponding to and slidably engaged with the guide rods are provided on both sides of the rotating seat; and third compression springs abutting against the lower bottom surfaces of the sliding sleeves at corresponding positions are sleeved on the two guide rods;

[0012] Note: When the mounting base and the external bracket are fixed, the rotating base slides downward along the guide rod under the action of the third compression spring, so that the locking strip approaches the clamping base, and the clamping base is fixed in a limited position; this prevents the mounting base from being separated from the external bracket during the use of the laser rangefinder body, thereby affecting the measurement accuracy.

[0013] Furthermore, a second gear ring is sleeved on another mounting shaft, a second gear box is arranged on the outer wall of the support frame and at a position corresponding to the position of the second gear ring, a second adjusting rod is slidably engaged with the second gear box, and a second gear meshingly connected with the second gear ring is sleeved on the second adjusting rod; the first adjusting rod is slidably engaged with the first gear box, and a first return spring abutting against an inner wall of the first gear box is sleeved on the first adjusting rod; a second return spring connected to the inner wall of the second gear box is sleeved on the second adjusting rod; the diameter of the second gear ring is larger than the diameter of the first gear ring, and the diameter of the second gear is smaller than the diameter of the first gear;

[0014] Description: Since the diameter of the second gear ring is larger than that of the first gear ring, and the diameter of the second gear is smaller than that of the first gear, when the first gear rotates, the rotation speed of the mounting shaft connected to the first gear ring is higher, and the adjustment range of the laser rangefinder body is larger; and when the second gear rotates, the rotation speed of the mounting shaft connected to the second gear ring is lower, and the adjustment range of the laser rangefinder body is smaller; therefore, during use of the utility model, the second adjustment rod is first pulled outward from the support frame to disengage the second gear from the second gear ring; the pitch angle of the laser rangefinder body is preliminarily adjusted by the first adjustment rod; then the first adjustment rod is pulled outward from the support frame to disengage the first gear from the first gear ring, and the pitch angle of the laser rangefinder body is accurately adjusted by the second adjustment rod, which not only improves the efficiency of the laser rangefinder body in measuring angle adjustment, but also improves the accuracy of measuring angle adjustment.

[0015] Furthermore, damping gears are arranged inside the first gear box and the second gear box; auxiliary gears are sleeved on the two mounting shafts and meshedly connected with the damping gears at corresponding positions one by one;

[0016] Description: By utilizing the meshing action of the damping wheel and the auxiliary gear, a certain damping effect is achieved when the first adjusting rod and the second adjusting rod are rotated, so that the user can accurately control the rotation speed of the first adjusting rod and the second adjusting rod.

[0017] Furthermore, a limiting groove is arranged on the upper end surface of the rotating seat, a limiting clamping plate movably engaged with the limiting groove is arranged on the lower bottom surface of the supporting frame, and a roller abutting against the limiting groove is arranged on the limiting clamping plate;

[0018] Description: By utilizing the clamping effect of the roller and the limit groove, the flow and stability of the support frame when rotating on the rotating seat can be improved.

[0019] The working principle of the utility model is:

[0020] When in use, the mounting seat is fixed on the external bracket, and the laser rangefinder body and the two positioning shafts inside the support frame are fixed by bolts; when the measuring angle of the laser rangefinder body needs to be adjusted, the adjusting worm is rotated, and the adjusting worm is used to drive the bevel gear to rotate, so that the support frame drives the laser rangefinder body to rotate horizontally on the rotating seat, and the measuring angle of the laser rangefinder body in the horizontal direction is adjusted; the first adjusting rod is rotated, and the first gear drives the first gear ring to rotate. During the rotation of the first gear ring, the positioning shaft connected to the first gear ring is used to drive the laser rangefinder body to rotate vertically inside the support frame, and the measuring angle of the laser rangefinder body in the vertical direction is adjusted.

[0021] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0022] First, the utility model has a reasonable structural design. By rotating the support frame to be connected to the rotating seat, the laser rangefinder body is rotated and connected to the support frame, so that the utility model can fully adjust the laser rangefinder body in the horizontal and vertical directions, thereby improving the convenience of use of construction measurement;

[0023] Second, the utility model uses two sets of gears with different diameters to adjust the pitch angle of the laser rangefinder body, which not only improves the response speed of the laser rangefinder body when adjusting the pitch angle, but also improves the adjustment accuracy, which has a promoting effect on improving the accuracy of construction measurement data;

[0024] Thirdly, the utility model is applicable to construction surveying work in different scenarios by arranging a clamping seat capable of clamping external brackets of different shapes on the mounting seat, thereby improving the application scope of the utility model.

[0041] When the mounting seat 1 is clamped on the external bracket through the mounting groove 10, the two clamping seats 11 approach each other under the action of the first compression spring 12 and clamp and fix the external bracket; at the same time, each follower rod 13 can be adaptively adjusted according to the shape of the external bracket, thereby improving the convenience and reliability of the mounting seat 1 during installation and disassembly.

[0043] The difference between this embodiment and embodiment 2 is that:

[0044] like Figure 1 , 4 As shown, locking strips 200 penetrating the mounting seat 1 are provided on both sides of the lower bottom surface of the rotating seat 20, and the lower bottom surfaces of the two locking strips 200 are provided with teeth that can be movably engaged with the clamping seat 11; guide rods 14 are provided on both sides of the upper end surface of the mounting seat 1, and sliding sleeves 201 corresponding to and slidably engaged with the guide rods 14 are provided on both sides of the rotating seat 20; and third compression springs 140 are sleeved on the two guide rods 14 and abut against the lower bottom surfaces of the sliding sleeves 201 at corresponding positions;

[0045] When the mounting base 1 is fixed to the external bracket, the rotating base 20 slides downward along the guide rod 14 under the action of the third compression spring 140, so that the locking strip 200 is close to the clamping base 11, and the clamping base 11 is limited and fixed; thereby preventing the mounting base 1 from being separated from the external bracket during use of the laser rangefinder body 4 and affecting the measurement accuracy.

[0049] Since the diameter of the second gear ring 34 is greater than that of the first gear ring 31, and the diameter of the second gear 360 is smaller than that of the first gear 330, when the first gear 330 rotates, the speed of the mounting shaft 30 connected to the first gear ring 31 is higher, and the adjustment range of the laser rangefinder body 4 is larger; when the second gear 360 rotates, the speed of the mounting shaft 30 connected to the second gear ring 34 is lower, and the adjustment range of the laser rangefinder body 4 is smaller; so that during the use of the utility model, the second adjustment rod 36 is first pulled out of the support frame 21 to disengage the second gear 360 from the second gear ring 34; the pitch angle of the laser rangefinder body 4 is preliminarily adjusted by the first adjustment rod 33; then the first adjustment rod 33 is pulled out of the support frame 21 to disengage the first gear 330 from the first gear ring 31, and the pitch angle of the laser rangefinder body 4 is accurately adjusted by the second adjustment rod 36, which not only improves the efficiency of the laser rangefinder body 4 in measuring angle adjustment, but also improves the accuracy of measuring angle adjustment.
