[0035] like Figure 1-10 The measuring instrument is described in detail as shown below:

[0036] A measuring instrument comprises a square plate 101, wherein the four corners of the plate 101 are provided with sockets 102, wherein a sliding column 202 is inserted and slidably inserted into the socket 102, wherein a vertical rod 201 is coaxially fixed to the upper end of the sliding column 202, wherein four vertical rods 201 are vertically penetrated with mounting holes 203, wherein a spherical ring 301 is provided above the center of the plate 101, wherein four square rods 302 are uniformly fixed to the outer circumference of the spherical ring 301, wherein sleeves 204 are slidably provided on the four square rods 302, wherein the four sleeves 204 are respectively inserted into the four mounting holes 203, wherein a central ball 401 is placed in the spherical ring 301, wherein a vertical rod 402 is threadedly connected to the lower end of the central ball 401, wherein the axis of the vertical rod 402 penetrates the center of the central ball 401, and wherein the lower ends of the four square rods 302 are fixed There is a fixed ring 304 coaxial with the spherical ring 301, and a rotating ring 501 is rotatably mounted on the fixed ring 304. A connecting plate 502 is fixed to one side of the rotating ring 501, and an arc plate 503 with an angle scale is fixed to the lower end of the connecting plate 502. An annular groove 305 is provided on the outer surface of the fixed ring 304, and a control frame 505 runs through the connecting plate 502. An insert plate 504 is provided near the end of the fixed ring 304 of the control frame 505. A spring I 506 is provided between the control frame 505 and the connecting plate 502, so that the insert plate 504 is inserted into the annular groove 305, forming a limit for the rotating ring 501 on the fixed ring 304, ensuring that the arc center of the arc plate 503 and the center of the center ball 401 are in the same plane, and the plane is perpendicular to the axis of the spherical ring 301.

[0037] When in use, the measuring instrument is assembled. After completion, the flat plate 101 is placed on the ground to be measured. At this time, the vertical rod 402 will be suspended below the central ball 401 due to its own gravity, and the central ball 401 will rotate in the spherical ring 301, so that the vertical rod 402 is vertically suspended perpendicular to the horizontal plane, and then the arc plate 503 is used as the back plate, and the projection of the vertical rod 402 on the arc plate 503 is observed from the front, and the scale lines on the arc plate 503 correspond to each other, so as to obtain the angle of the measured ground; and, because it is unclear what state the ground to be measured is in when the flat plate 101 is placed, when reading, the rotating ring 501 should be rotated on the fixed ring 304, that is, the arc plate 503 can be rotated with the fixed ring 304 as the axis, so as to observe circumferentially, and the maximum value is the ground inclination angle, if the circumferential observation values ​​are all zero, that is, the ground to be measured is horizontal ground; thereby achieving the purpose of facilitating the measurement of the ground inclination angle;

[0038] In order to facilitate the carrying of the measuring instrument of the present application, the measuring instrument is in a scattered state when not in use, so it needs to be assembled when in use; during assembly, first insert the sliding column 202 at the lower end of the four vertical rods 201 into the four sockets 102; then take the spherical ring 301 and align it with the center of the flat plate 101, then slide the sleeve 204 away from the spherical ring 301 and insert it into the four mounting holes 203 to fix the spherical ring 301; put the center ball 401 into the spherical ring 301 from above, and then thread the vertical rod 402 on the center ball 401 at the lower end; take the rotating ring 501 and press the control frame 505 to squeeze the spring I 506, so that the plug plate 504 is close to the connecting plate 502, and then put the rotating ring 501 on the fixed ring 304, and then release the control frame 505, the elastic force of the spring I 506 will make the plug plate 504 inserted into the ring groove 305, and the assembly of the measuring instrument is completed.

[0039] Further:

[0040] In order to obtain a better reading, a steel wire 403 is coaxially extended from the lower end of the vertical rod 402, and the steel wire 403 corresponds to the arc plate 503. Since the diameter of the steel wire 403 is small, the value can be better observed.

[0041] Further:

[0042] An extension rod 404 is fixed to the lower end of the steel wire 403 , and a weight ball 405 is fixed to the lower end of the extension rod 404 .

[0043] By providing the weighted ball 405 , the steel wire 403 can be better suspended in a vertical horizontal plane, thereby ensuring the accuracy of the measurement.

[0044] Further:

[0045] The extension rod 404 is threadedly connected with a sheath 406 , and the sheath 406 can be rotated so that the upper end of the sheath 406 is sleeved on the vertical rod 402 to protect the steel wire 403 .

[0046] Since the steel wire 403 has a small diameter, it is easy to break or bend the steel wire 403 after being retracted. Therefore, a sheath 406 is provided. When retracting, the sheath 406 is rotated so that the sheath 406 moves axially on the extension rod 404 through a thread until the upper end of the sheath 406 is sleeved on the vertical rod 402, thereby protecting the steel wire 403.

[0047] like Figure 1-10 As shown:

[0048] The square rod 302 is penetrated by a long hole 303 , and the sleeve 204 is threadedly connected with a limit screw 206 , and the limit screw 206 slides in the long hole 303 .

[0049] By allowing the sleeve 204 to slide axially on the square rod 302, it is convenient to control the plug-in installation of the sleeve 204 and the mounting hole 203, and then facilitate the installation of the spherical ring 301. However, after being folded, in order to prevent the sleeve 204 from slipping off the square rod 302, which will be more time-consuming and labor-intensive during the next installation, a limit screw 206 is set to slide in the long hole 303, so as to prevent the sleeve 204 from slipping off the square rod 302.

[0050] Further:

[0051] A spring II 205 is provided between the square rod 302 and the sleeve 204 .

[0052] By setting spring II 205, the sleeve 204 can be pushed away from the spherical ring 301, so that the sleeve 204 remains away from the spherical ring 301. After the sleeve 204 is inserted into the mounting hole 203 to complete the installation of the spherical ring 301, the measuring instrument can maintain this state to avoid one of the sleeves 204 automatically sliding out of the mounting hole 203, causing inaccurate measurement results.

[0053] like Figure 1-10 As shown:

[0054] A key edge 104 is disposed in the insertion hole 102 , and a key slot matching the key edge 104 is disposed on the sliding column 202 , so that the virtual axis of the mounting hole 203 at the upper end of the vertical rod 201 intersects perpendicularly with the virtual axis of the center of the flat plate 101 .

[0055] Through the cooperation between the key edge 104 and the key groove, after the slide column 202 is installed with the plate 101, the mounting hole 203 of the upper vertical rod 201 thereof faces or corresponds to the spherical ring 301, thereby facilitating installation.

[0056] like Figure 1-10As shown:

[0057] It also includes four leg columns 601 , each of which has a sliding column 602 at its upper end. The plate 101 is evenly penetrated with a plurality of circular holes 103 , and the sliding column 602 can be inserted into the circular holes 103 so that the leg columns 601 support the plate 101 .

[0058] The support leg column 601 and the plate 101 are attracted to each other by magnetic force.

[0059] Since the flat panel 101 is a plate structure, when it is placed on the ground, it will be affected by the bottom surface of the flat panel 101. When there are debris on the ground, it will be impossible to measure the ground. Therefore, four supporting legs 601 are provided so that the flat panel 101 can contact the ground through the supporting legs 601, so that the flat panel 101 can be placed better. Moreover, due to the presence of the plurality of circular holes 103, the positions of the four supporting legs 601 can be adjusted arbitrarily to support the flat panel 101.

[0060] The support leg column 601 and the flat plate 101 are attracted to each other by magnetic force, so that the position of the support leg column 601 can be adjusted at will while ensuring that the support leg column 601 will not fall off the flat plate 101 automatically.

[0061] like Figure 1-10 As shown:

[0062] An assembly process for the measuring instrument, the assembly process comprising:

[0063] S1, first insert the sliding posts 202 at the lower ends of the four vertical rods 201 into the four insertion holes 102;

[0064] S2, then take the spherical ring 301 and align it with the center of the flat plate 101, then slide the sleeve 204 away from the spherical ring 301 and insert it into the four mounting holes 203 to fix the spherical ring 301;

[0065] S3, placing the central ball 401 into the spherical ring 301 from above, and then threading the vertical rod 402 onto the central ball 401 from below;

[0066] S4. Take the rotating ring 501 and press the control frame 505 to make the plug plate 504 close to the connecting plate 502, then put the rotating ring 501 on the fixed ring 304, and then loosen the control frame 505 to insert the plug plate 504 into the ring groove 305 to complete the assembly of the measuring instrument.
