Description

Technical Field

[0001] This utility model relates to the field of measuring instruments, and in particular to a relative height measuring device. Background Technology

[0002] Currently, the measurement and layout of the thickness and relative height of structures are mostly achieved using a spirit level and a measuring tape. The spirit level is used to determine a reference horizontal plane, and the measuring tape measures the height relative to this reference horizontal plane. When operating alone, it is necessary to control two rulers simultaneously, and the eyes need to observe the level bubble and read the value at the same time, which is very inconvenient. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide a relative height measuring device to address the problem that it is very inconvenient for a single person to simultaneously control two rulers and observe the level bubble and read the value when measuring and setting out the thickness and relative height of a structure.

[0004] This utility model provides a relative height measuring device, comprising:

[0005] A spirit level has a groove and a first groove on its surface, and a second groove inside. The groove and the second groove are connected to each other, the first groove and the second groove are connected to each other, and the first groove and the second groove are perpendicular to each other.

[0006] The vertical ruler is slidably connected in the first groove and is perpendicular to the horizontal ruler.

[0007] The scale assembly is located between the upper end of the vertical ruler and the second groove;

[0008] A reading amplifier, installed in the groove, is used to amplify the measurement scale of the scale assembly in the second slide.

[0009] A locking nut is installed between the level and the vertical ruler.

[0010] In one embodiment, the scale assembly includes a measuring tape disc and a guide wheel rotatably connected in a second groove. A measuring tape spring is driven between the measuring tape disc and the guide wheel. One end of the measuring tape spring is wound around the measuring tape disc, and the other end of the measuring tape spring is fixed to the upper end of the vertical ruler. A scale strip is provided on the measuring tape spring, and the guide wheel is located at the intersection of the vertical ruler and the horizontal ruler.

[0011] In one embodiment, the surface of the spirit level is provided with a guide groove, which is connected to the first sliding groove, and the measuring tape spring and the scale strip are located in the guide groove.

[0012] In one embodiment, the reading amplifier includes a convex glass and a mounting base, the mounting base being fixed in a groove, the convex glass being fixed on the mounting base, and a scale pointer being disposed inside the convex glass.

[0013] In one embodiment, a long level bubble is mounted on the surface of the level.

[0014] In one embodiment, a third groove is provided at the bottom of the ruler, and a positioning top rod is slidably connected in the third groove. A compression spring is fixedly connected between the positioning top rod and the ruler.

[0015] The aforementioned relative height measuring device directly reads the measurement scale value of the scale assembly in the second slide groove through a reading amplifier to obtain the height of the object to be measured relative to a reference point. This conforms to measurement habits and improves measurement efficiency. Since the measurement scale is perpendicular to the line of sight, the accuracy of the measurement results is improved. At the same time, it can be operated by a single person, and the operation steps are simple and convenient for reading. Attached Figure Description

[0029] The following is combined with Figures 1-5 This invention describes a relative height measuring device.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, a relative height measuring device includes a level 100, a vertical ruler 200, a scale assembly 300, and a reading amplifier 400.

[0031] The surface of the level 100 has a groove 110 and a first slide 120, and the interior of the level 100 has a second slide 130. The groove 110 and the second slide 130 are interconnected, the first slide 120 and the second slide 130 are interconnected, and the first slide 120 and the second slide 130 are perpendicular to each other.

[0032] The vertical ruler 200 is slidably connected in the first groove 120, and the vertical ruler 200 is perpendicular to the horizontal ruler 100.

[0033] The scale assembly 300 is located between the upper end of the vertical ruler 200 and the second slide groove 130.

[0034] The reading amplifier 400 is installed in the groove 110 and is used to amplify the measuring scale of the scale assembly 300 in the second slide 130.

[0035] A locking nut 500 is installed between the level 100 and the vertical ruler 200.

[0036] When the relative height measuring device is initially set, with the lower end of the ruler 200 at a height of "0", the value read by the scale assembly 300 is set to "0". During use, when the point to be measured is lower than the reference point, the level 100 is placed on the surface of the height reference point, and then the locking nut 500 is loosened. The ruler 200 will fall onto the surface of the object under its own weight. At this time, the correct height reading on the scale assembly 300 is located in the reading amplifier 400. The reading amplifier 400 reads the measurement scale value of the scale assembly 300 within the second slide groove 130, which is the height of the object relative to the reference point. When the point to be measured is higher than the reference point, the level 100 is placed on the surface of the point to be measured, and then the locking nut 500 is loosened. The ruler 200 will fall onto the surface of the reference point under its own weight. At this time, the reading amplifier 400 reads the measurement scale value of the scale assembly 300 within the second slide groove 130, which is the height of the object relative to the reference point.

[0037] This relative height measuring device directly reads the measurement scale value of the inner scale assembly 300 of the second slide groove 130 through the reading amplifier 400 to obtain the height of the object to be measured relative to the reference point. This conforms to measurement habits and improves measurement efficiency. Since the measurement scale is perpendicular to the line of sight, the accuracy of the measurement results is improved. At the same time, it can be operated by a single person, and the operation steps are simple and convenient for reading.

[0038] In this embodiment, see Figure 4 The ruler assembly 300 includes a measuring tape disc 310 and a guide wheel 330 rotatably connected in the second slide groove 130. A measuring tape spring 340 is connected between the measuring tape disc 310 and the guide wheel 330. One end of the measuring tape spring 340 is wound around the measuring tape disc 310, and the other end of the measuring tape spring 340 is fixed to the upper end of the vertical ruler 200. A ruler belt 320 is provided on the measuring tape spring 340. The guide wheel 330 is located at the intersection of the vertical ruler 200 and the horizontal ruler 100.

[0039] It should be noted that during use, the measuring tape spring 340 will automatically retract and wind around the measuring tape reel 310.

[0040] In this embodiment, a guide groove 140 is provided on the surface of the level 100. The guide groove 140 is connected to the first sliding groove 120. The measuring tape spring 340 and the scale strip 320 are located in the guide groove 140.

[0041] Because the measuring tape spring 340 and the scale band 320 move within the guide groove 140 during the measurement process, the portion of the measuring tape spring 340 on the side wall of the ruler 200 remains in close contact with the ruler 200, further improving the accuracy of the measurement results.

[0042] In this embodiment, see Figure 2The reading amplifier 400 includes a convex glass 410 and a mounting base 420. The mounting base 420 is fixed in the groove 110, and the convex glass 410 is fixed on the mounting base 420. A scale pointer 430 is provided inside the convex glass 410.

[0043] The convex glass 410 serves to amplify the reading.

[0044] In this embodiment, a long level bubble 600 is installed on the surface of the level ruler 100 to facilitate observation of whether the level ruler 100 is level.

[0045] In this embodiment, see Figure 5 The bottom of the ruler 200 is provided with a third sliding groove 210. A positioning top rod 220 is slidably connected in the third sliding groove 210. A compression spring 230 is fixedly connected between the positioning top rod 220 and the ruler 200. Under pressure, the positioning top rod 220 can be completely retracted into the ruler 200, thereby facilitating the accurate positioning of the center point of the ruler 200.

[0046] The steps for using this relative height measuring device are as follows:

[0047] 1. Before use, relative height measuring devices that have not been used for a long time or have shown deviations during testing need to be calibrated. Select a platform that has been tested with a spirit level and place the spirit level 100 on its surface. Observe whether the long level bubble 600 indicates that it is horizontal. If there is a deviation, adjust the mounting base 420 to adjust the spirit level 100 to be horizontal.

[0048] 2. During measurement, when the point to be measured is lower than the reference point, place the level 100 on the surface of the height reference point, adjust the position of the level 100 so that the long level bubble 600 indicates horizontal, loosen the locking nut 500, and the vertical ruler 200 will fall onto the surface of the object to be measured under its own weight, and press the positioning rod 220 into the vertical ruler 200. At this time, the tape measure disc 310 will wind the scale tape 320 into a taut state, so that the correct height reading is located in the reading amplifier 400. Then, read the value on the scale tape 320 at this time through the reading amplifier 400, which is the height of the object to be measured relative to the reference point.

[0049] 3. During measurement, when the point to be measured is higher than the reference point, place the level 100 on the surface of the point to be measured, adjust the position of the level 100 so that the long level bubble 600 indicates horizontal, loosen the locking nut 500, and the vertical ruler 200 will fall on the surface of the reference point under its own weight, and press the positioning rod 220 into the vertical ruler 200. At this time, the tape measure disc 310 will wind the scale tape 320 into a taut state, so that the correct height reading is located in the reading amplifier 400. Then, read the value on the scale tape 320 at this time through the reading amplifier 400, which is the height of the object to be measured relative to the reference point.

[0050] 4. When laying out a structure of known height, move the vertical ruler 200 downwards within the second slide groove 130 until the reading on the scale band 320 is at the desired laying height. Then, tighten the locking nut 500. The height exposed at the bottom of the vertical ruler 200 is the desired laying height. At this point, place the level 100 on the surface of the height reference point and adjust the long level bubble 600 to indicate horizontality. The bottom position of the vertical ruler 200 is the desired laying height. Alternatively, place the bottom of the vertical ruler 200 on the surface of the height reference point and adjust the long level bubble 600 to indicate horizontality. The bottom position of the level 100 is the desired laying height. The operation is simple and convenient.

[0051] It should be noted that each relative height measuring device can be marked with a reference value, so that the reference value does not need to be measured repeatedly during use. At the same time, the relative height measuring device can also be used to measure thickness. The steps for measuring thickness are the same as those for measuring the height of the relative reference point, and will not be repeated here.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
