DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1-Figure 4 , a control point height measurement auxiliary device, comprising: a tripod 1, a foundation pit 2, a fixing block 4, an insert block 5, a vertical plate 7, a tape measure 3, a slider 10, a fixing rod 11, and an adjustment component;

[0025] First, a fixing block 4 is provided on the tripod 1 for stably fixing the device on the tripod 1, and a foundation pit 2 is pre-set in the ground to be measured, and a control point 8 is installed inside the foundation pit 2, which is a reference point for measuring the height;

[0026] The plug block 5 is plugged into one side of the fixed block 4, and the vertical plate 7 is connected to the fixed block 4 through the plug block 5. A slide groove is provided on one side of the vertical plate 7, and a slider 10 is slidably connected in the slide groove. A fixed rod 11 is slidably connected inside the slider 10. A fastening groove is provided at one end of the fixed rod 11 for installing the tape measure 3. One end of the tape measure 3 is fixed in the fastening groove, and the other end is drooped to contact and measure the height of the control point 8.

[0027] In order to fix the position of the tape measure 3 on the fixed rod 11, a screw 13 is installed at one end of the fixed rod 11, and the other end of the screw 13 is threadedly connected with a nut. By tightening the nut, it can be ensured that the tape measure 3 is tightly fixed on the fixed rod 11 and can be adjusted autonomously according to the depth of the control point 8;

[0028] In order to adjust the tape measure 3 horizontally, an adjustment component is also provided, which includes a slide post 14, which is fixedly connected to one side of the slider 10 and penetrates the vertical plate 7 and is slidably connected to the vertical plate 7. A plurality of teeth 15 are provided on one side of the slide post 14, and a plug-in block 17 is fixedly connected to one side of the vertical plate 7. A tooth block 16 is plugged into the plug-in block 17, and the tooth block 16 can mesh with a section of teeth 15 on the slide post 14. By moving the slide post 14, the slider 10 is driven to slide in the slide groove and mesh with different teeth 15, so that the horizontal position of the slider 10 and the tape measure 3 fixed thereon can be adjusted to ensure that the tape measure 3 is in a tensioned state during measurement, thereby improving the detection accuracy.

[0029] In order to facilitate the adjustment of the position of the tape measure 3 on the fixed rod 11, the upper surface of the slider 10 is also threadedly connected with a screw 12, the bottom of the screw 12 is in contact with the fixed rod 11, the fixed rod 11 slides inside the slider 10, and the screw 12 is rotated to achieve further adjustment of the position of the tape measure 3.

[0030] Example 2

[0031] refer to Figure 1-Figure 4 , improved on the basis of Example 1:

[0032] In order to facilitate reading the measured value of the tape measure 3, a reading rod 18 is fixedly connected to one side of the vertical plate 7. The reading rod 18 is provided with a scale, which can be aligned with the scale of the tape measure 3, so that the measured value can be read quickly and accurately;

[0033] In addition, in order to enhance the connection stability between the tape measure 3 and the control point 8, a magnet 9 is fixedly connected to the bottom of the tape measure 3, and the magnet 9 is magnetically connected to the control point 8. When the tape measure 3 droops and contacts the control point 8, the magnet 9 will be attracted to the control point 8 to prevent the tape measure 3 from moving due to wind or vibration.

[0034] It should be noted that the height of the magnet 9 is added when reading the scale on the tape measure (or a tape measure with a certain hardness) 3;

[0035] In order to further enhance the structural stability of the device, plug rods 6 are respectively inserted on both sides of the fixed block 4, and the plug rods 6 pass through the plug block 5. Through the insertion of the plug rods 6, it can be ensured that the connection between the plug block 5 and the fixed block 4 is more secure, preventing shaking or displacement during the measurement process.
