Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a free-falling needle-shaped thickness gauge for construction, which solves the problem that the thickness gauge for construction inspection uses a hand-held measuring needle. Although it can measure, manual setting is easy to damage the measuring needle. Ontology, and manual operation will also affect the accuracy of its measurement, which is not convenient for the use of building inspections

Embodiment 1

[0035] Such as Figure 1-5 As shown, the present invention provides a technical solution: a free-falling needle thickness gauge for construction, including a base plate 1 and a pressure plate 2, the pressure plate 2 and the base plate 1 are movably connected by a connecting bracket 3, and the connecting bracket 3 There are positioning nuts 11 threaded on the surface of the plate, a measuring hole 4 is provided in the center of the pressure plate 2, 6-8 groups of square grooves 5 are provided on the inner side of the measuring hole 4, and a chute 6 is provided on both sides of the inner wall of the square groove 5. And the thickness measuring device 7 is arranged in the measuring hole 4, and the auxiliary magnetic suction type support device 8 is arranged in the square groove 5. By setting the thickness measurement device 7 and the auxiliary magnetic suction type support device 8, it is better than the prior art, ensuring The 707 measuring needle is inserted into the measured o...

Embodiment 2

[0038] Such as Figure 1-5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: the auxiliary magnetic support device 8 includes two sets of connecting rods 801, and one end of the connecting rods 801 is connected to the side of the chute 6 away from the thickness measuring device 7 , and the other side is fixedly connected with the other end of the chute 6 through the magnet block A802, the surface of the connecting rod 801 is movably connected with an iron slider 803, and the two iron sliders 803 of each group are fixedly connected Fixed rod 804 is arranged, and the outer surface of fixed rod 804 is movably connected with eccentric wheel 805, and chute 6 is arranged on the top of square groove 5 inner walls, and the bottom of eccentric wheel 805 and square groove 5 inner walls is provided with spacing, guarantees eccentric wheel 805 in When rotating, it will not rub against or block the square groove 5, which is convenient for long-ter...

Embodiment 3

[0040] Such as Figure 1-5 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the distance between two magnet blocks B806 on the same horizontal plane after complete magnetic attraction is smaller than the diameter of the measuring needle 707, so that the next time The measuring needle 707 can be in contact with the eccentric wheels 805 on both sides when it falls freely, which can not only protect the measuring needle 707, but also improve the accuracy of its measurement.

Abstract

The invention belongs to the technical field of building detection and relates to a free falling type needle-shaped thickness gauge for a building. The free falling type needle-shaped thickness gaugecomprises a bottom plate and a pressing plate; the pressing plate and the bottom plate are movably connected through a connecting bracket; a positioning screw cap is in threaded connection with the surface of the connecting bracket; a measuring hole is formed in the center of the pressing plate; 6 to 8 groups of square grooves are formed in the inner side of the measuring hole; a slide groove is formed in each of two sides of the inner wall of each square groove; a thickness measuring device is arranged in the measuring hole; and auxiliary magnetic suction type supporting devices are arrangedin the square grooves. According to the free falling type needle-shaped thickness gauge of the invention, the thickness measuring device and the auxiliary magnetic suction type supporting devices areadopted, and therefore, a measuring needle can be inserted into an object to be measured when the measuring needle falls down freely; a user does not need to hold the measuring needle; the body of themeasuring needle will not be damaged; the measuring accuracy of the measuring needle is not influenced; and the application of the thickness gauge to building detection is facilitated.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a free-falling needle-shaped thickness gauge for buildings. Background technique [0002] At present, in the construction industry, the asphalt road surface needs to be tested, and it needs to be tested by its thickness gauge. Furthermore, it calculates the thickness of the object to be measured by inserting the detection needle into the object to be measured and detecting the insertion depth of the needle. [0003] And in the comparison patent, the application number is CN201720364893.7 a kind of needle-shaped thickness gauge, its technical solution points support, vertically arranged on the scale body on the support, slidingly connected to the reading block on the scale body and fixed on the reading block Although the measuring needle on the block can guarantee the advantages of verticality, there are still some disadvantages, such as: need to hold the measuring nee...
