Description

Technical Field

[0001] The invention belongs to the field of measurement technology, and more specifically, particularly relates to a construction measurement device. Background Art

[0002] During the construction process, foundation engineering (including walls, columns, beams, floor slabs, pipes, etc.) needs to be regularly measured to check whether they meet the markings. Most of these measurements rely on tape measures to complete linear measurements such as length and thickness. Therefore, tape measures need to be frequently used and recorded when measuring foundation engineering. However, there are currently the following problems when measuring foundation engineering data at construction sites:

[0003] 1. The tape measure, pen, recording paper and other measuring tools needed for measurement need to be carried to the measurement site by the surveyor. The surveyor often carries a backpack to store the tools. However, it is obviously inconvenient to take out the tape measure from the backpack every time the tool is used, which needs to be used frequently. However, if the surveyor always holds the tape measure, paper and pen in his hand, there will be a problem of restricted movement, which makes it inconvenient to touch, knock, take photos and other measurement operations on the construction site;

[0004] 2. In construction measurement, when measuring shorter dimensions with high precision requirements (such as the side length and thickness of small components), and measuring linear dimensions in narrow spaces (such as the side length of the inner frame of a window frame), the tape measure may not be able to be used, and a ruler with finer scales is needed. When measuring longer distances (such as the length and width of a room, the height of a building, etc.), measuring and laying out a large range of sites (such as determining the boundary range of a construction site), and measuring some linear dimensions that are difficult to directly touch at both ends (such as the vertical distance from a higher position to the ground), a tape measure is needed for measurement. Both tape measures and rulers have high usage requirements, and it is inconvenient to frequently switch and take the two rulers;

[0005] 3. When recording measurement data, there is often a lack of stable support. Operators often need to lie on the ground or wall or use other supporting objects to record. This recording method will affect the convenience of recording and handwriting, resulting in the recorded data being unsightly or difficult to recognize. At the same time, due to the dusty characteristics of construction sites, it is also easy to dirty the recording and measuring tools.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, the strap is a common adjustable elastic strap on the market. The strap is put on the forearm of the inspector near the elbow and tied tightly. When the operator needs to conduct a test, the operator can quickly measure the length, thickness or other linear dimensions by switching the position of the installation base plate, and quickly record them. A series of operations can be completed with the left hand alone, freeing the operator's right hand, and when no measurement is needed, the strap can be retracted at the forearm to free the inspector's hands, thereby improving convenience and portability.

[0027] 2. When no measurement is required, the status of the entire device is as follows: Figure 1 As shown, at this time, the base is vertically inserted into the sleeve block two, and the connecting screw is rotated so that the end of the connecting screw passes through the connecting grooves on the base and the sleeve block two to achieve the effect of fixing the position of the base. At this time, the entire device is retracted to the outside of the forearm, and the operator does not need to hold the device with both hands, which frees the operator's hands and allows the operator to use both hands normally for other operations when no measurement operation is required. The device can be worn on the forearm for a long time, which improves convenience. Freeing up both hands allows the wearer to perform difficult actions such as supporting and climbing with both hands, which is especially suitable for the complex terrain of construction sites and improves the safety of the wearer.

[0028] 3. When the operator arrives at a certain place on the construction site and needs to measure, he turns the connecting screw with his right hand to release the limit on the base. At this time, he can hold the handle with his right hand to lift the mounting base plate to separate the mounting base plate from the connecting rod. Then, he holds the handle composed of the two handles with his left hand. The left thumb is stuck in the thumb sleeve and pushed to the right to insert the connecting column into the bottom groove. After releasing the left thumb, the limit block is inserted into the annular groove under the elastic force of the second spring, so that the connecting column remains in the bottom groove and cannot be separated. At this time, the operator can hold the handle to deflect the mounting base plate to improve the applicability of the angle during measurement. The state of the entire device is as follows: Figure 2 As shown, the effect of quickly switching the device state is achieved.

[0029] 4. When measuring shorter objects on the construction site, you can directly use the ruler on the mounting base to read the measurement. When measuring longer objects, you can hang the tape measure hook of the tape measure body on one end of the object to be measured. Then press the left end of the rotating rod with the index finger of your left hand so that the right end of the rotating rod drives the pressure block to no longer press against the tape of the tape measure. At this time, the measurement personnel can move and use the tape measure normally to measure longer objects. The measurement usage and reading are the same as the conventional tape measure. When the measurement is completed, you can loosen the tape measure. Open the index finger of your left hand to reset the pressure block and press the tape measure again. At this time, the tape measure can maintain the extended length, which is convenient for the measurement personnel to compare at another place without repeatedly pulling out the tape measure, thereby improving convenience. At the same time, after the measurement is completed, you can press the turning rod with the index finger of your left hand again to release the limit on the tape measure, so that the tape measure will automatically retract under the tension of the spring device inside the tape measure body. During the retraction process, both hands do not need to be close to the tape measure body, which improves safety and greatly avoids the measurement personnel's hands being scratched by the metal tape of the tape measure.

[0030] 5. During the measurement process, the operator controls the installation base plate with his left hand, and pushes the slide with his right hand to pull the water-based pen out of the pen slot, records the measurement data on a sticky note, and performs simple calculations. The installation base plate controlled by the left hand can act as a stable writing board, eliminating the need for the operator to lie on the ground or wall to record as in the traditional way, which improves the convenience of recording and the beauty of the recorded fonts. The tool box can store various small tools needed for measurement, further improving applicability and convenience.

[0031] 6. After the tape measure body is placed on the placement dish, the belt buckle on the side of the tape measure body is stuck on the side plate. Figure 3 The elastic rope tightens the outer shell of the tape measure body and is stuck in the slot. The elastic rope, side panels, placement dish and pressure plate together realize multi-directional limiting of the tape measure body, so that the tape measure body can be quickly disassembled and assembled while stabilizing its position, so as to replace the damaged tape measure or replace the tape measure of different lengths as needed. The multi-directional limiting of the tape measure body by the elastic rope, side panels, placement dish and pressure plate can be suitable for tape measures of different sizes, and has high applicability.

[0032] 7. A ruler slot and a limit slot are provided on the rear side of the mounting base plate. A card strip is movably connected in the ruler slot. A double-sided ruler is fixedly connected to the card strip. A limit screw is threadedly sleeved in the limit slot. A hole is provided on the card strip. The limit screw passes through the hole on the card strip. A pair of fixing frames are also fixedly connected to the upper surface of the mounting base plate. The ruler is a double-sided ruler. The scale on the upper surface of the ruler increases from zero from left to right, and the scale on the lower surface of the ruler also increases from zero from left to right. In this way, the operator can release the limit on the ruler by turning the limit screw and choose which side of the ruler is facing up according to actual needs, so that the zero scale of the ruler can be freely selected on the left or right, further improving the applicability. The limit screw can be used to quickly fix the ruler, and the card strip and ruler slot provide a limiting effect. BRIEF DESCRIPTION OF THE DRAWINGS

When measuring longer objects, the tape measure hook of the tape measure body 4 can be hung on one end of the object to be measured in length / thickness, and then the left index finger presses down the left end of the rotating rod 9 to make the right end of the rotating rod 9 The pressure block 48 is driven to no longer press against the tape of the measuring tape. At this time, the measuring personnel can move and use the measuring tape normally to measure a long object. The measurement usage and reading are the same as the conventional tape measurement method. When the measurement is completed, the left index finger can be released to reset the pressure block 48 and press against the tape again. At this time, the tape of the measuring tape can maintain the extended length, which is convenient for the measuring personnel to compare at another place without repeatedly pulling out the measuring tape, thereby improving convenience. At the same time, after the measurement is completed, the rotating rod 9 can be pressed again with the left index finger to release the limit on the measuring tape of the measuring tape, so that the measuring tape can automatically retract under the tension of the spring device inside the measuring tape body 4, and the hands do not need to be close to the measuring tape body 4 during the retraction process, thereby improving safety and greatly avoiding the measuring personnel's hands from being scratched by the metal tape of the measuring tape.

[0058] During the measurement process, the operator controls the mounting substrate 1 with his left hand, and can push the slide 24 with his right hand to pull the water-based pen 22 out of the pen slot 12, record the measurement data on the note paper 3, and perform simple calculations. The mounting substrate 1 controlled by the left hand can act as a stable writing board, and the operator no longer needs to lie on the ground or wall to record as in the traditional way, which improves the convenience of recording and the beauty of the recorded font.

[0059] Working principle:

[0060] When the device is in use, the strap 8 is a common adjustable elastic strap on the market. The strap 8 is put on the forearm of the inspector near the elbow and tied tightly. When the operator needs to perform a test, the operator can quickly measure the length, thickness or other linear dimensions by switching the position of the mounting substrate 1, and quickly record them. The left hand can complete a series of operations, freeing the operator's right hand, and when no measurement is needed, the strap can be retracted at the forearm to free the inspector's hands, thereby improving convenience and portability. Specifically:

[0061] When no measurement is required, the status of the entire device is as follows Figure 1As shown, at this time, the base 20 is vertically inserted into the sleeve block 30, and the connecting screw 59 is rotated so that the end of the connecting screw 59 passes through the connecting groove 21 on the base 20 and the sleeve block 30, so as to achieve the effect of fixing the position of the base 20. At this time, the whole device is retracted outside the forearm, and the operator does not need to hold the device with both hands, which frees the operator's hands and enables the operator to use both hands normally for other operations when the measurement operation is not required. The device can be worn on the forearm for a long time, which improves the convenience. Freeing the hands allows the wearer to perform difficult actions such as supporting and climbing with both hands, which is particularly suitable for the complex terrain of the construction site and improves the safety of the wearer.

[0062] When the operator arrives at a certain place on the construction site and needs to take measurements, he or she turns the connecting screw 59 with his or her right hand to release the limit on the base 20. At this time, he or she can hold the grip 37 with his or her right hand to lift the mounting base 1 and separate the mounting base 1 from the connecting rod 6. Then, he or she holds the handle composed of the two grips 37 with his or her left hand, and the left thumb is stuck in the thumb sleeve 44 and pushed to the right to insert the connecting column 41 into the bottom groove 27. Then, the operator releases the left thumb, and the limit block 43 is stuck in the annular groove 42 under the elastic force of the spring 2 39, so that the connecting column 41 remains in the bottom groove 27 and cannot be separated. At this time, the operator can hold the grip 37 to deflect the mounting base 1 to improve the applicability of the angle during measurement. The state of the entire device is as follows: Figure 2 As shown, the effect of quickly switching the device state is achieved;

[0063] When measuring shorter objects on a construction site, the ruler 11 on the mounting base 1 can be used directly to read the measurement. When measuring longer objects, the tape measure hook of the tape measure body 4 can be hung on one end of the object to be measured for length / thickness, and then the left index finger presses down the left end of the rotating rod 9 so that the right end of the rotating rod 9 drives the pressing block 48 to no longer press against the tape of the tape measure. At this time, the measurement personnel can move and use the tape measure normally to measure the longer object. The measurement usage and reading are the same as the conventional tape measure usage. When the measurement is completed, the tape measure can be loosened. The left index finger is opened to reset the pressure block 48 and press the tape measure again. At this time, the tape measure can maintain the extended length, which is convenient for the measurement personnel to compare at another place without repeatedly pulling out the tape measure, which improves convenience. At the same time, after the measurement is completed, the left index finger can be used to press the rotating rod 9 again to release the limit on the tape measure, so that the tape measure automatically retracts under the tension of the spring device inside the tape measure body 4. In the process of retraction, both hands do not need to be close to the tape measure body 4, which improves safety and greatly avoids the measurement personnel's hands from being scratched by the metal tape measure.

[0064] During the measurement process, the operator controls the mounting substrate 1 with his left hand, and can push the slide 24 with his right hand to pull the water-based pen 22 out of the pen slot 12, record the measurement data on the note paper 3, and perform simple calculations. The mounting substrate 1 controlled by the left hand can serve as a stable writing board, and the operator does not need to lie on the ground or wall to record like the traditional way, which improves the convenience of recording and the beauty of the recorded font;

[0065] Tool box 2 can store various small tools needed for measurement, further improving applicability and convenience;

[0066] After the measuring tape body 4 is placed on the placing dish 14, the belt buckle on the side of the measuring tape body 4 is clamped on the side plate 56. Figure 3 The elastic rope 57 is clamped on the outer shell of the tape measure body 4 and then stuck in the card slot 58. The elastic rope 57, the side plate 56, the placement dish 14 and the pressure plate 51 jointly realize the multi-directional limitation of the tape measure body 4, so that the tape measure body 4 can be quickly disassembled and assembled while being in a stable position, so as to replace the damaged tape measure or replace the tape measure of different lengths as needed. The multi-directional limitation of the tape measure body 4 by the elastic rope 57, the side plate 56, the placement dish 14 and the pressure plate 51 can be applicable to tape measures of different sizes, and has high applicability.
