In geological exploration, mineral development, water conservancy, transportation and other construction, control measurement, mine measurement, route measurement and topographic mapping must be carried out for geological surveys and various building design and construction. Among them, surveying and mapping staff need to use levels and cooperate with level rulers to carry out elevation control measurements, elevation measurements, etc.

[0003] A circular level bubble is fixed on the body of the level rod, and its horizontal and vertical relationship with the body of the rod remains relatively unchanged. During the operation, personnel need to observe the circular level bubble and make the level rod reach a vertical state by centering it to carry out leveling operations. However, due to frequent use of the level rod, human bumps, bumps and vibrations during transportation and other factors, the level bubble on the body of the level rod will often shift, making it impossible to keep the level rod in a vertical state through the level bubble.

[0004] Traditional level rod verticality correction equipment is large in size and high in cost, while the manual observation and correction method is inconvenient for personnel to operate, time-consuming and labor-intensive, thus increasing the difficulty of level rod verticality correction.

[0005] Therefore, those skilled in the art provide a device for correcting the verticality of a level rod to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 6 As shown, this embodiment provides a level ruler verticality correction device, including a ruler box 1, and also includes:

[0027] The mounting components are symmetrically arranged on both sides of the outer wall of the ruler box 1 and are used to fix the ruler box 1 on the wall;

[0028] A fixing component is arranged on one side of the ruler box 1 and is used to fix the level ruler inside the ruler box 1;

[0029] The reinforcing component is symmetrically arranged on one side of the ruler box 1 and is used to further fix the leveling ruler inside the ruler box 1, thereby effectively improving the stability of the leveling ruler.

[0030] The above working principle: when the level rod needs to be calibrated for verticality, it is only necessary to first fix the ruler box 1 in the calibration place by installing the components, and then fix the level rod inside the ruler box 1 by fixing the components and strengthening the cooperation between the components. At this time, the level rod can be kept in a vertical state inside the ruler box 1. After the level rod is fixed, the adjuster observes the state of the level bubble on the level rod, and then adjusts the screw under the level bubble to center the level bubble, thereby realizing the calibration of the level rod. It is easy and simple, effectively saves time and energy, and can effectively avoid the disadvantages of the calibration method of manual observation, which is time-consuming and labor-intensive, and requires the cooperation of multiple people.

[0031] In order to conveniently and once fix the ruler box 1 in the calibration place, the installation assembly includes L-shaped connectors 5 symmetrically arranged on both sides of the outer wall of the ruler box 1, and multiple L-shaped connectors 5 are each provided with mounting holes 6 inside, and multiple mounting holes 6 are each provided with fastening screws 7 inside, and multiple fastening screws 7 are each symmetrically provided with nuts 8 outside. When it is necessary to fix the ruler box 1 in the calibration place, it is only necessary to fix the L-shaped connector 5 in the designated position by fastening screws 7 and nuts 8. At this time, the ruler box 1 can be fixedly installed, so as to facilitate the use of the ruler box 1. The staff can also further adjust the state of the device by adjusting the nuts 8 outside the multiple fastening screws 7.

[0032] Taking into account that when the level ruler is adjusted, it is necessary to first fix the level ruler inside the ruler box 1, so a plurality of threaded holes are opened on one side of the ruler box 1, and the fixing assembly includes a limit screw 9 arranged inside the plurality of threaded holes. When the level ruler needs to be fixed inside the ruler box 1, it is only necessary to first place the level ruler that needs to be adjusted inside the ruler box 1, and then rotate the limit screw 9. At this time, the limit screw 9 will move inside the threaded hole. When the limit screw 9 contacts the outside of the level ruler, the level ruler can be fixed inside the ruler box 1 by the limit screw 9, thereby facilitating the staff to adjust the level ruler.

[0033] In order to further enhance the fixing effect of the device on the level ruler, the strengthening component includes a connecting plate 3 symmetrically arranged on one side of the ruler box 1, and the two connecting plates 3 are symmetrically provided with sliding rods 10 inside, and the two ends of the sliding rods 10 are respectively fixedly connected to the two sides of the inner wall of the connecting plate 3, and the two connecting plates 3 are provided with a movable plate 11 inside, and the two movable plates 11 are provided with a guide groove for the movement of the sliding rod 10 inside, and the outer parts of the multiple sliding rods 10 are sleeved with a return spring 12, and the multiple return springs 12 are in contact between the movable plate 11 and the connecting plate 3, one side of the two movable plates 11 is fixedly connected with a fixed plate 13, and the other side of the two fixed plates 13 is fixedly connected with a pull plate, and the other side of the two movable plates 11 is symmetrically provided with connecting rods 14, and the other end of each two connecting rods 14 is fixedly connected with a clamping plate 15, and the two connecting plates 3 and the ruler box are fixedly connected. 1 are provided with guide grooves for the movement of the connecting rod 14. When the level ruler needs to be fixed, it is only necessary to pull the pull plate first. At this time, the pull plate will drive the fixed plate 13 to move synchronously, and the fixed plate 13 will drive the movable plate 11 to move synchronously outside the slide bar 10. During the movement of the movable plate 11, the reset spring 12 will be squeezed, and the movable plate 11 will also drive the connecting rod 14 and the clamping plate 15 to move synchronously. At this time, the level ruler is placed inside the ruler box 1, and the pull plate is released. At this time, the reset spring 12 is reset, driving the movable plate 11 to move synchronously, and the movable plate 11 will drive the connecting rod 14 and the clamping plate 15 to move synchronously. When the clamping plate 15 contacts the outside of the level ruler, the clamping plate 15 can be used to further improve the fixing effect of the level ruler, thereby making the fixing of the level ruler more stable.

[0034] In order to prevent the level rod from being not vertical after being placed in the ruler box 1 due to the protrusion of the flat plate at the bottom of the level rod, a back plate 2 is provided inside the ruler box 1. Through the setting of the back plate 2, the level rod can be auxiliaryly limited, thereby preventing the level rod from being not vertical after being placed in the ruler box 1 due to the protrusion of the flat plate at the bottom of the level rod, thereby affecting the adjustment effect of the level rod.

[0035] In addition, in order to fix the level rod at one point, a hemispherical ruler point 4 is provided at the inner bottom end of the ruler box 1. By setting the hemispherical ruler point 4, the level rod can be fixed at one point, thereby effectively improving the adjustment effect of the level rod.
