It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a portable measuring device for construction sites includes a fixed plate 1, guide columns 2, a platform plate 3, a movable plate 4, a functional rod 5, and a locking assembly 7. The fixed plate 1 is a rectangular plate, and the guide columns 2 are cylindrical. Two guide columns 2 are symmetrically arranged on the upper surface of the fixed plate 1 near the rear end. The movable plate 4 is also a rectangular plate, and it has two first through holes 402 corresponding to the guide columns 2, thus allowing the movable plate 4 to be movably connected to the guide columns 2. The movable plate 4 moves up and down along the guide columns 2. The space between the movable plate 4 and the fixed plate 1 is used to place the object to be measured. The platform plate 3 is connected to the top of the guide columns 2. The fixed plate 1, movable plate 4, and platform plate 3 have the same width, thus maintaining the same width throughout the device. The functional rod 5 is a cylindrical rod, and its lower end is connected to the upper surface of the movable plate 4. The locking assembly... 7 is connected to the front end of the platform plate 3. The locking assembly 7 includes a rod sleeve 71 and a locking bolt 72. The rod sleeve 71 is a hollow cylindrical sleeve. The rod sleeve 71 is fitted over the functional rod 5. The locking bolt 72 passes through the side wall of the rod sleeve 71. The side wall of the rod sleeve 71 is provided with a threaded hole corresponding to the locking bolt 72. When the locking bolt 72 is tightened, the top of the locking bolt 72 abuts against the outer wall of the functional rod 5 to position the functional rod 5. When the locking bolt 72 is loosened, the functional rod 5 can move up and down inside the rod sleeve 71. The outer wall of the functional rod 5 is provided with a scale mark 51. When the object to be measured is placed between the movable plate 4 and the fixed plate 1, the movable plate 4 moves upward and drives the functional rod 5 to move upward. The scale line of the scale mark 51 corresponding to the bottom of the lower end of the rod sleeve 71 is the reading value, which is the thickness of the object to be measured.
[0026] like Figure 2As shown, the fixed plate 1 includes a first plate body 11, a second plate body 12, and a hinge 13. The first plate body 11 is located at the rear end and is fixedly connected to the guide post 2. The second plate body 12 is located at the front end and is rotatably connected to the first plate body 11 via the hinge 13. The second plate body 12 can rotate upwards around the hinge 13. The front-to-back length of the first plate body 11 is less than the front-to-back length of the platform plate 3. When the second plate body 12 rotates to be perpendicular to the first plate body 11, the foremost point of the second plate body 12 does not exceed the foremost point of the rod sleeve 71. The second plate body 12 includes a ramp plate 121, which is located at the front end of the second plate body 12 to facilitate guiding the fixed plate 1 to move to the underside or side of the object to be measured.
[0027] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the movable plate 4 includes a third plate body 41 and a fourth plate body 42. Two first through holes 402 are provided in the third plate body 41, and the third plate body 41 is movably connected to the guide post 2. The third plate body 41 is provided with a first threaded hole 401 near the front end, and the lower end of the functional rod 5 is provided with an external thread 52 corresponding to the first threaded hole 401, so that the functional rod 5 is detachably connected to the third plate body 41 by means of a threaded connection. The fourth plate 42 is detachably connected to the third plate 41. The front side of the third plate 41 is provided with a first slot 411, which has two grooves arranged vertically. The first slot 411 is a T-shaped groove. The rear side of the fourth plate 42 is provided with a corresponding insertion block 421, which also has two grooves arranged vertically. The insertion block 421 is a T-shaped block. When in use, the insertion block 421 is inserted into the corresponding first slot 411 from the left or right side, thereby connecting the fourth plate 42 and the third plate 41. The upper surface of the third plate 41 is also provided with a second slot 412, which is located behind the first threaded hole 401. The second slot 412 corresponds to the insertion block 421 and is a T-shaped groove. The second slot 412 has two grooves arranged front and rear. When the fourth plate 42 is separated from the front end of the third plate 41, it is inserted into the corresponding second slot 412 through the insertion block 421, and the fourth plate 42 can be connected above the third plate 41. The lower end face of the third plate 41 is provided with a first receiving groove 413. The shape of the first receiving groove 413 corresponds to the tip of the ramp plate 121, and when the second plate 12 rotates upward around the hinge 13, the tip of the ramp plate 121 can be accommodated in the first receiving groove 413.
[0028] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the third plate 41 is provided with a first storage groove 414, which is located at the middle of the rear end of the third plate 41. The shape of the first storage groove 414 corresponds to the functional rod 5, and the inner diameter of the first storage groove 414 corresponds to the diameter of the functional rod 5. Thus, the functional rod 5 can be secured to the third plate 41 through the first storage groove 414. The inner wall of the first storage groove 414 is provided with a buffer layer made of rubber to protect and secure the functional rod 5. When the functional rod 5 is placed in the first storage groove 414, it is located between the two guide posts 2. The rear end of the platform plate 3 is provided with a second storage groove corresponding to the functional rod 5, and the rear end of the first plate 11 is provided with a third storage groove corresponding to the functional rod 5. When the functional rod 5 needs to be stored, the middle of the functional rod 5 is secured in the first storage groove 414, the upper end of the functional rod 5 is secured in the second storage groove, and the lower end of the functional rod 5 is secured in the third storage groove. The restriction of the three positions can fix the functional rod 5 and prevent it from moving.
[0029] like Figure 1 and Figure 2 As shown, an ultrasonic thickness gauge is connected to the platform plate 3. The ultrasonic thickness gauge includes a main unit 91 and a probe 92. The main unit 91 is mounted on the platform plate 3, and the probe 92 is electrically connected to the main unit 91 via a connecting cable. A bracket corresponding to the probe 92 is provided on the front surface of the platform plate 3. When not in use, the probe 92 is placed on the bracket. When in use, a coupling agent is applied to the probe 92, and the probe 92 is placed on the object to be measured. When the ultrasonic pulse emitted by the probe 92 passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe 92. The thickness of the object is determined by measuring the propagation time of the ultrasonic wave in the material. In this embodiment, the ultrasonic thickness gauge uses the existing ST500 ultrasonic thickness gauge with a resolution of 0.1 / 0.01 mm and a measurement range of 0.75-300 mm. Alternatively, a Defelsko C Advanced 200C3-E ultrasonic coating thickness gauge can be used, which can measure the coating thickness of substrates such as concrete and fiberglass, and can measure the thickness of up to three coatings.
[0030] In use, when it is necessary to measure the thickness of materials and samples such as boards, MDF, and glass, the movable plate 4 is lifted upwards to place the sample on the fixed plate 1, or the fixed plate 1 is placed against the sample. The movable plate 4 is then moved downwards to place it against the sample surface. The thickness of the sample is then read from the scale line corresponding to the lowest scale mark 51 at the bottom of the rod sleeve 71. When it is necessary to measure the thickness of a sample that cannot be held or to measure the thickness of a sample coating, a coupling agent is applied to the probe 92 and it is placed on the sample. The parameters can be read from the display screen on the main unit 91.
[0031] When the device is stored, the movable plate 4 is moved upward, the second plate 12 rotates upward around the hinge 13 so that the second plate 12 is perpendicular to the first plate 11, and the third plate 41 moves downward so that the tip of the ramp plate 121 is accommodated in the first receiving groove 413. The fourth plate 42 is removed from the front end of the third plate 41, and the insert 421 of the fourth plate 42 is inserted into the second slot 412. The main body length of the fourth plate 42 is equal to the distance from the upper end face of the third plate 41 to the lower end face of the platform plate 3 at this time, so that the fourth plate 42, the third plate 41 and the second plate 12 will not shake when stored. The function rod 5 is turned to remove it from the third plate 41, and the function rod 5 is locked in the first storage groove 414 to complete the storage. At this time, the rear end of the device does not exceed the back of the platform plate 3, and the front end does not exceed the front of the rod sleeve 71. The components do not shake during the carrying process, making it convenient for workers to carry to the construction site.
[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
