Description

Technical Field

[0001] The present application relates to the technical field of rulers, and in particular to a ruler that is convenient for measurement. Background Art

[0002] A ruler is mainly used to detect the verticality and flatness of a plane. It usually has a long and straight ruler body, generally made of metal or other solid materials. The ruler body may have scales to read the measurement data more accurately. The ruler is widely used in construction, decoration and other fields. In construction, it can be used to detect whether the construction quality of walls, floors, etc. meets the standards; in decoration, it can be used to check the flatness of the wall, etc. When using a ruler, make sure it fits tightly with the measured surface to obtain accurate measurement results. At the same time, pay attention to correctly reading the scale and judging whether the measurement data meets the requirements. Rulers of different types and specifications may differ in function and accuracy.

[0003] After checking the announcement number: CN216049639U, a ruler is disclosed. This technology discloses "including a first ruler body and a measuring unit, the first ruler body is cylindrical to form a through slot that runs through the first ruler body along the long axis of the first ruler body, and the two side walls of the first ruler body are respectively provided with a first through slot and a second through slot that are connected to the through slot; the measuring unit is slidably connected to the through slot, the measuring unit includes a measuring head extending outward through the first through slot, the measuring head is used to measure the distance between the abutment surface of the first ruler body and the surface to be measured, and the measuring unit also includes a shift block extending outward through the second through slot, etc., which has the advantages that when measuring with a ruler, there is no need to borrow a wedge ruler, and the measurement can be performed directly through the ruler in this application, thereby simplifying the measurement steps; and the measuring unit directly measures the distance through the measuring head, which is more accurate than manual degrees, and reduces the measurement error and other technical effects";

[0004] With respect to the above-mentioned related technologies, the inventors believe that most of the existing rulers are too long and difficult to carry, which is not convenient for situations where the work location needs to be frequently moved. Secondly, most of the existing rulers are measured manually, and it is impossible to ensure whether they are parallel to the ground, resulting in errors in the measurement results.

[0005] In view of the above-mentioned related technologies, the inventor believes that a ruler that is easy to measure is needed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the present application is to provide a ruler that is convenient for measurement, so as to improve the problem that the ruler is too long to be carried and the measurement result may have errors.

[0007] The present application provides a ruler that is convenient for measurement and adopts the following technical solution:

[0008] A ruler convenient for measuring comprises a first ruler, wherein the top end of the first ruler is fixedly connected to two rotating plates, and opposite ends of the two rotating plates are rotatably connected to a rotating rod, and one end of the rotating rod is fixedly connected to a second ruler, both ends of the first ruler and the second ruler are provided with scales, and the scales can be used to measure sizes, and one end of the first ruler and the second ruler are slidably connected to two measuring blocks, and the measuring blocks are used to record sizes, and one end of the two measuring blocks is fixedly connected to a fixed block, and one end of the first ruler and the second ruler is provided with a fixing groove used for matching with the fixing block, and the two fixing blocks on the same vertical side are connected to the fixing groove in a damping sliding manner, and the top end of the second ruler is provided with a first rectangular groove, and the lower inner wall of the first rectangular groove is slidably connected to two clamping plates, and the opposite ends of the two clamping plates are commonly fixedly connected to a telescopic rod, and the outer surface of the telescopic rod is provided with a spring, and the top ends of the two clamping plates are fixedly connected to clamping blocks, and the top end of the first ruler is provided with a second rectangular groove, and the inner walls on both sides of the second rectangular groove are provided with through-type clamping grooves.

[0009] By adopting the above technical solution, when it is necessary to measure a longer size, first rotate the second ruler. The rotation of the second ruler will drive the two clamping blocks to rotate. When the two clamping blocks rotate into the second rectangular groove, due to the special shape of the clamping blocks, the two clamping blocks will be squeezed. The two clamping blocks will drive the two clamping plates to move. The two clamping plates will jointly squeeze the spring and generate elastic force. Under the action of the telescopic rod, the two clamping plates can be made more stable when moving. Then continue to rotate the second ruler. The second ruler will drive the two clamping blocks into the two clamping grooves. The elastic force of the spring will clamp the two clamping blocks in the clamping grooves. When the measurement is completed, press the two clamping blocks and then rotate the second ruler.

[0010] Optionally, a long groove is formed at the bottom end of the first ruler, an outer rod is fixedly connected to the upper inner wall of the long groove, an inner rod is slidably connected to the inner surface of the outer rod, and a spirit level is fixedly connected to the bottom end of the inner rod. The spirit level can keep the first ruler and the second ruler perpendicular to the ground during measurement.

[0011] By adopting the above technical solution, before measuring, you first need to ensure that the ruler is level by observing the spirit level. When the measured height is too high, pull the spirit level, which can drive the inner rod to move out of the long slot. Placing the spirit level on the ground can also play a certain supporting role.

[0012] Optionally, a through circular groove is formed at one end of the first ruler, a short rod is movably sleeved on the inner surface of the circular groove, two long plates are fixedly connected at both ends of the short rod, a connecting plate is fixedly connected at opposite ends of the two long plates, and a handle is fixedly connected to the bottom end of the connecting plate.

[0013] By adopting the above technical solution, when it is necessary to observe and measure the size, since observing from the bottom up will lead to large errors, it is necessary to hold the handle, place the second ruler and the second ruler close to the wall, and rotate the handle upward to drive the connecting plate and the two long plates to rotate, so that the measurement value can be observed from the front, making the detection more accurate.

[0014] Optionally, one end of the first ruler is fixedly connected to an angle reading screen.

[0015] The above technical solution is used to display the measured angle.

[0016] Optionally, a limiting groove is provided at the bottom end of the first rectangular groove, and the bottom ends of the two clamping plates are fixedly connected with limiting blocks used in conjunction with the limiting groove.

[0017] By adopting the above technical solution, the two splints can be made more stable during movement.

[0018] Optionally, the size of the first ruler is the same as that of the second ruler and they are distributed in a mirror image.

[0019] By adopting the above technical solution, the device can be made more portable.

[0020] Optionally, a transverse groove is formed at the bottom end of the first ruler, and the inner surface of the transverse groove fits with the outer surface of the level.

[0021] By adopting the technical solution, a level meter can be placed, and accurate measurement results can be obtained when measuring from the ground.

[0022] Optionally, the angle between the level and the first ruler is ninety degrees.

[0023] By adopting the above technical solution, it is convenient to adjust the measuring angle.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The present application provides a first ruler and a second ruler, and under the action of two clamping blocks and two clamping grooves, the first ruler and the second ruler can be stably connected, so that the device is not only easy to carry but also can measure longer dimensions;

[0026] 2. The present application uses a level, in which the inner rod and the outer rod are used to pull the level and place it on the ground, and then observe the level to keep it parallel, so that the measurement result can be more accurate. BRIEF DESCRIPTION OF THE DRAWINGS
