Description

Technical Field

[0001] The utility model relates to the technical field of distance measuring instruments and discloses a distance measuring instrument for engineering cost. Background Art

[0002] When conducting project cost calculation, forecasting and analyzing project cost, it is usually necessary to refer to various data of the project. We often use a rangefinder, which is a tool for measuring length or distance. Place the rangefinder on a bracket and fix it, then measure it using the rangefinder.

[0003] However, the patents in the prior art have the following disadvantages:

[0004] (1) The height of the rangefinder cannot be adjusted. In the actual measurement process, in order to improve the accuracy of the ranging data, it is often necessary to measure targets in different directions and at different heights in the same horizontal plane.

[0005] (2) It is inconvenient to adjust the direction of the rangefinder, and the entire device needs to be lifted to adjust the direction of the rangefinder. Utility Model Content

[0006] The utility model aims to provide a distance meter for engineering cost, which solves the problem that the height of the distance meter cannot be adjusted and the direction of the distance meter is inconvenient to adjust in the prior art by arranging a lifting component and a rotating component.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A distance meter for engineering cost, comprising:

[0009] A base, wherein the four corners of the bottom end of the base are provided with universal wheels;

[0010] A support column, the bottom end of which is fixedly connected to the base, and a tooth groove is provided on one side surface of the support column;

[0011] A sleeve rod, wherein the sleeve rod is sleeved with a support column;

[0012] A lifting assembly, wherein the lifting assembly is located at the left end of the sleeve rod;

[0013] A mounting frame, the mounting frame is located above the sleeve rod, a slide groove is provided on the upper surface of the mounting frame, a double-headed screw is provided inside the slide groove, both left and right ends of the double-headed screw are rotatably connected to the mounting frame, both left and right end surfaces of the double-headed screw are sleeved with clamping plates, a knob is connected to the right end of the double-headed screw, and a rangefinder body is provided inside the mounting frame;

[0014] A rotating assembly is located inside the sleeve rod.

[0015] Furthermore, the lifting assembly comprises:

[0016] The outer shell is fixedly connected to the sleeve rod, a support rod is arranged inside the outer shell, a transmission rod is arranged at one end of the support rod, a button is arranged at one end of the transmission rod, and the button is sleeved on the outer shell.

[0017] A locking block, the locking block is fixedly connected to the transmission rod, and the locking block passes through the sleeve rod;

[0018] A return spring, wherein the left and right ends of the return spring are respectively fixedly connected to a button and a sleeve rod.

[0019] Furthermore, the locking block is engaged with the tooth groove.

[0020] Furthermore, the transmission rod is rotatably connected to the support rod.

[0021] Furthermore, the rotating assembly comprises:

[0022] A rotating shaft, the bottom of the rotating shaft is rotatably connected to a sleeve rod, and the bottom end of the rotating shaft is provided with a first bevel gear;

[0023] A rocker is rotatably connected to a sleeve rod, a second bevel gear is arranged at the left end of the rocker, and the first bevel gear is meshed with the second bevel gear.

[0024] Furthermore, the upper end of the rotating shaft is fixedly connected to the mounting frame.

[0025] The utility model provides a distance meter for engineering cost, which has the following beneficial effects:

[0026] (1) The utility model solves the problem that the existing engineering cost rangefinder cannot adjust the height of the rangefinder by providing a lifting assembly. Pressing a button can cause the locking block to slide out of the tooth groove, lift the sleeve rod to a suitable height, and then release the button. The reset spring will push the button to reset and cause the locking block to engage the tooth groove, so that the sleeve rod is fixed on the support column, thereby realizing the adjustment of the rangefinder height.

[0027] (2) The utility model solves the problem that the direction of the existing engineering cost distance meter is inconvenient to adjust by setting a rotating assembly. By rotating the rocker, the rocker drives the rotating shaft to rotate through the first bevel gear and the second bevel gear, thereby rotating the mounting frame to adjust the direction of the distance meter.
