Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, and more specifically, to a relative height measuring ruler. Background Art

[0002] Height measuring ruler, also known as height vernier caliper, is a measuring instrument that uses the vernier principle to read the distance between the working surface of the marking claw installed on the ruler frame or the relative movement of the measuring head and the working surface of the base. It has high accuracy and high reliability and can be used to measure the height size and relative position of the workpiece and perform precision marking operations.

[0003] In the current market, although there are many types of measuring rulers, the purpose of most products is relatively single, mainly limited to a specific measurement need. In actual measurement work, it is often necessary to use a variety of measuring instruments in combination to ensure the comprehensiveness and accuracy of the measurement. This leads to the need for operators to frequently pick up and replace different measuring instruments, such as optical levels, vertical measuring instruments, and infrared levels, when measuring, which undoubtedly increases the complexity and time cost of the operation. Not only that, this method of using them in batches is also prone to introduce errors in the measurement process. Because each time the instrument is replaced, it needs to be readjusted and calibrated, which not only increases the possibility of errors, but also may cause deviations in the measurement data between different instruments. In addition, since various instruments may differ in accuracy and measurement principles, it is difficult to ensure the accuracy of measurement in multiple dimensions using only one instrument.

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figures 1 to 5 As shown, the utility model provides a relative height measuring ruler, comprising a steel pipe 1, a measuring ruler 2 is movably installed inside the steel pipe 1, an optical level 3 is arranged on the top of the measuring ruler 2, a limit sleeve 4 is movably installed at the connection between the steel pipe 1 and the measuring ruler 2, and a vertical detector 5 is arranged at the bottom of the limit sleeve 4;

[0023] A sleeve device 6 is movably mounted on the surface of the steel pipe 1, a connecting plate 7 is fixedly mounted on the surface of the sleeve device 6, a connecting column 9 is fixedly mounted on the top of the connecting plate 7, one end of the connecting column 9 is hingedly connected to a hinged plate 8, a ball rod 18 is arranged on the top of the hinged plate 8, and a support leg 10 and a support leg 2 11 are hingedly connected to the bottom of the hinged plate 8;

[0024] An adjusting device 12, the adjusting device 12 is movably mounted on the surface of the steel pipe 1, a lifting plate 13 is movably mounted inside the adjusting device 12, and an infrared level 14 is arranged on the surface of the lifting plate 13;

[0025] Cone 21, cone 21 is respectively fixed at the bottom of steel pipe 1, leg 10 and leg 2 11;

[0026] When in use, after moving the device to the position to be measured, insert the cone 21 into the ground, then open the hinge plate 8 so that the cones 21 at the bottom of the first leg 10 and the second leg 11 are inserted into the ground to fix the entire device, then adjust the infrared level 14 to see if they are on the same horizontal plane, and then use the vertical detector 5 to check whether the device is vertical, and then use the optical level 3 to measure;

[0027] After the cone 21 at the bottom of the steel pipe 1 is inserted into the ground, the hinged plate 8 is opened so that the cones 20 at the bottom of the leg one 10 and the leg two 11 are also inserted into the ground. Then, the horizontal and vertical heights are detected by the infrared level 14 and the vertical measuring instrument 5, and then measured by the optical level 3. Compared with the traditional device, this device combines the infrared level 14, the vertical measuring instrument 5 and the optical level 3 during measurement, which can bring significant benefits in improving measurement accuracy, improving measurement efficiency, enhancing the diversity of measurement functions and improving operation convenience, providing strong support for various measurement work.

[0028] A bolt groove 19 is provided on the inner wall of the sleeve device 6, and a bolt 20 is movably installed inside the bolt groove 19;

[0030] The handle 17 is held and turned to rotate the rotating rod 16 . The rotation of the rotating rod 16 causes the internal protrusion to be in close contact with the surface of the steel pipe 1 , thereby fixing the hinge plate 8 as a whole, so as to better perform the measurement.

[0033] The inner diameter of the optical level 3 is equal to the outer diameter of the measuring ruler 2, and the shape of the hinged plate 8 is a herringbone;

[0034] By setting the inner diameter of the optical level 3 and the outer diameter of the measuring ruler 2 to be equal in size, the optical level 3 fits more closely when put on the top of the measuring ruler 2, thereby preventing the optical level 3 from falling off. The shape of the hinged plate 8 is a herringbone, which has stability.

[0035] Among them, the steel pipe 1, the leg 1 10 and the leg 2 11 are equal in size, and the outer diameter value of the measuring ruler 2 is equal in size to the inner diameter value of the steel pipe 1;

[0036] Setting the sizes of the steel pipe 1, the first leg 10 and the second leg 11 to be equal will be more convenient in use. The outer diameter value of the measuring ruler 2 is equal to the inner diameter value of the steel pipe 1, so that the measuring ruler 2 and the steel pipe 1 fit better.

[0037] The working principle and use process of this utility model:

[0038] When in use, after moving the device to the position to be measured, insert the cone 21 into the ground, and then open the hinged plate 8 so that the cones 21 at the bottom of the leg 10 and the leg 2 11 are inserted into the ground to fix the entire device. Then adjust the infrared level 14 to see if they are on the same horizontal plane, and use the vertical detector 5 to check whether the device is vertical, and then measure with the optical level 3.
