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] like 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 obje...

Embodiment 2

[0038] like 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-term u...

Embodiment 3

[0040] like 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 relates to the technical field of building detection, in particular to a free-falling needle-shaped thickness gauge for buildings, which includes a bottom plate and a pressure plate, and the pressure plate and the bottom plate are movably connected by a connecting bracket, and the surface of the connecting bracket is A positioning nut is threadedly connected, a measuring hole is opened in the center of the pressure plate, 6-8 groups of square grooves are opened on the inner side of the measuring hole, a chute is opened on both sides of the inner wall of the square groove, and the measuring A thickness measuring device is arranged in the hole, and an auxiliary magnetic support device is arranged in the square groove. The present invention is superior to the prior art through the setting of the thickness measuring device and the auxiliary magnetic support device, and ensures that the measuring needle is inserted into the object to be measured when it falls freely, and does not need to be used by hand, and will not damage the measuring needle body , It will not affect the accuracy of its measurement, which is convenient for the use of building inspection.

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...
