Description

Technical Field

[0001] The utility model relates to the technical field of slope meters, in particular to a portable slope measuring instrument. Background Art

[0002] The slope meter is a surveying and mapping accessory product with slope measurement function. The slope meter uses the back plane of the antenna to rotate the scale wheel to center the bubble in the level tube, and the degree indicated by the indicator needle on the dial is the degree of the downtilt angle. However, the existing slope meters have the following disadvantages:

[0003] After the slope meter is placed on the slope surface, it is necessary to manually turn the wheel to adjust the bubble level, and the bubble level is completely determined by the human eye, which will result in a small error, resulting in a certain error in the final reading, and it is troublesome to use the adjustment hand wheel each time. Secondly, when the slope meter is used outdoors, it is placed directly on the ground, and the bottom of the shell will be worn, thus affecting subsequent use. Therefore, the utility model proposes a portable slope measuring instrument. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a portable slope measuring instrument.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a portable slope measuring instrument, comprising a shell, one side of the shell is open, and the open side of the shell is fixedly connected to a cover plate, one side of the cover plate is provided with a reserved opening, an outer ring plate is fixedly connected inside the shell and close to the reserved opening, a bearing is fixedly connected to the inner wall of the outer ring plate, the inner ring of the bearing is fixedly connected to the inner ring plate, a rotating component for driving the inner ring plate to rotate is provided inside the inner ring plate, a plurality of cross bars are fixed to the inner wall of the shell and located outside the outer ring plate, a plurality of the cross bars are fixedly connected to an annular panel at one end close to the reserved opening, a connecting rod is fixed to the top of the inner ring plate close to the side of the annular panel, the other end of the connecting rod passes through the circular hole in the middle of the inner ring plate and is fixedly connected to a pointer, and a protective component is fixedly connected to the bottom end of the shell.

[0012] Beneficial effects of the utility model:

[0013] 1. When the utility model is in use, the portable slope measuring instrument is provided with a shell, a panel, an outer ring plate, a bearing, an inner ring plate, a rotating assembly, an annular panel and a pointer. After the measuring instrument is placed on the slope, the counterweight block of the rotating assembly will drive the inner ring plate to rotate under the action of gravity, so that the level tube of the rotating assembly is always in a horizontal state. When the inner ring plate rotates, the inner ring plate drives the pointer to rotate, and finally the scale indicated by the pointer is read as the slope value. The measuring instrument does not need to manually adjust the level tube, so the measurement is more convenient, and the measurement accuracy is higher than that of manual adjustment.

[0014] 2. When the utility model is in use, the portable slope measuring instrument is provided with a pad, a side plate and a locking bolt. The pad is located at the bottom of the shell. The pad is in contact with the ground to prevent the shell from being worn. If the pad is worn out due to long-term use, the pad can be disassembled and replaced, which is more flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-Figure 3 As shown, it relates to a portable slope measuring instrument, including a shell 1, one side of the shell 1 is open, and a cover plate 2 is fixedly connected to the open side of the shell 1, a reserved opening 3 is opened on one side of the cover plate 2, an outer ring plate 4 is fixedly connected inside the shell 1 and near the reserved opening 3, a bearing 5 is fixedly connected to the inner wall of the outer ring plate 4, an inner ring of the bearing 5 is fixedly connected to an inner ring plate 6, a rotating component 7 for driving the inner ring plate 6 to rotate is provided inside the inner ring plate 6, a plurality of cross bars 8 are fixed to the inner wall of the shell 1 and located outside the outer ring plate 4, a plurality of cross bars 8 are fixedly connected to an annular panel 9 at one end near the reserved opening 3, a connecting rod 10 is fixed to the top of the inner ring plate 6 near the side of the annular panel 9, the other end of the connecting rod 10 passes through the circular hole in the middle of the inner ring plate 6 and is fixedly connected to a pointer 11, and a protective component is fixedly connected to the bottom end of the shell 1.

[0023] like Figure 1-Figure 3 As shown, the rotating assembly 7 includes two side seats 71 symmetrically fixed to the inner wall of the inner ring plate 6, the connecting line between the two side seats 71 passes through the center of the inner ring plate 6, the lower surfaces of the two side seats 71 are fixedly connected with inclined rods 72, and the bottom ends of the two inclined rods 72 are commonly fixedly connected with counterweight blocks 73.

[0024] Since the inner ring plate 6 can rotate freely inside the outer ring plate 4 through the bearing 5 , when the outer shell 1 is tilted, the inner ring plate 6 will be pulled to rotate automatically under the drive of the counterweight block 73 .

[0025] like Figure 1-Figure 3 As shown, a level tube 74 is fixedly connected between the two side seats 71 .

[0026] During use, the inner ring plate 6 may get stuck. At this time, whether the bubble of the level tube 74 is centered can be observed to assist in judging whether the measurement is accurate.

[0027] like Figure 1 As shown, a scale line 12 is provided on the surface of the annular panel 9 and close to the pointer 11 .

[0028] The inclination of the measured slope can be read by the scale position pointed by the pointer 11.

[0029] like Figure 1 As shown, a transparent plate 13 is fixedly connected inside the reserved opening 3 .

[0030] The transparent plate 13 can protect the components inside the housing 1, and the scale lines 12 on the surface of the annular panel 9 inside the housing 1 can be seen through the transparent plate 13.

[0031] like Figure 1-Figure 2 As shown, the housing 1 and the cover plate 2 are provided with a hand hole 14 on one side away from the reserved opening 3. The hand hole 14 is convenient for taking the device.

The backing plate 15 can be disassembled by loosening the locking bolts 17, which is convenient for cleaning or replacing the backing plate 15.

[0034] Working principle: Place the measuring instrument on the slope, and the counterweight 73 will automatically droop. The drooping action of the counterweight 73 will pull the inner ring plate 6 to rotate a specified angle through the inclined rod 72, and the inner ring plate 6 will then drive the connecting rod 10 and the pointer 11 to rotate. When the inner ring plate 6 is stationary, the scale on the scale line 12 pointed by the pointer 11 is the slope of the slope. When using the measuring instrument, there is no need to manually adjust the level tube 74, which is more convenient to use.
