Description

Technical Field

[0001] The utility model belongs to the technical field of crack width measuring instruments, in particular to a crack detection device for prefabricated concrete components. Background Art

[0002] The crack width gauge is a tool specifically used to measure the width of cracks in concrete structures. It can help engineers and inspectors quickly and accurately determine the width of cracks, thereby evaluating the integrity and safety of concrete structures. The crack width gauge is mainly used to test the crack width of concrete structures. The principle is to collect images of cracks in real time through a microscopic camera and display the magnified crack image on the host. Users can read the width of cracks through an electronic scale or ruler on the screen to evaluate the integrity and safety of concrete structures. Most cracks in precast concrete components are also detected by crack width gauges.

[0003] A Chinese patent with publication number CN213932429U discloses a crack width gauge for bridge inspection, including a crack width gauge body, an upper end surface of the crack width gauge body is provided with an inspection baffle, the inspection baffle is threadedly connected to the crack width gauge body through hexagonal rivets, and four hexagonal rivets are provided, one end of the crack width gauge body is provided with a gripping anti-slip sleeve, one side of the crack width gauge body is provided with a baffle, the baffle is rotatably connected to the crack width gauge body through a second rotating shaft, and two second rotating shafts are provided, a replacement socket is provided above the baffle, and the replacement socket is integrally built with the crack width gauge body.

[0004] The crack width gauge in the above-mentioned prior art still has certain shortcomings in actual operation and use. For example, when the crack width gauge is in use, the user generally holds the main body in one hand and the camera mechanism in the other hand to collect images of the cracks. However, when engineers need to detect and calculate cracks in precast concrete components, they need to take images of the cracks and then perform calculations through the host. However, the calculations are often performed with both hands, requiring both holding the crack width gauge body and using the touch screen to magnify the crack image and set the calculation value. Therefore, most users will directly loosen the camera mechanism connected to the wire, and the camera mechanism is also susceptible to collisions in a natural state, which in turn affects its service life. Utility Model Content

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

Through the fixing mechanism, the clamping mechanism can be quickly disassembled, assembled and used on the crack side width meter body.

[0010] As a preferred technical solution, a fixing block is symmetrically fixedly connected to the outer side of the mounting seat, fixing holes are symmetrically opened on the inner side of the fixing block, and connecting grooves are symmetrically opened on the outer side of the base.

One end of the second guide rod movably passes through the middle part of the second spring. A limiting slot is symmetrically provided on the inner side of the installation slot. The end of the movable plate is slidably connected to the inner side of the limiting slot. Through the slot, the card block can be conveniently snap-connected and fixed to the base at the installation seat. Through the second guide rod, the second spring can be conveniently protected.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] First, when the crack width meter body needs to be operated with both hands, the camera mechanism connected to the wire needs to be temporarily fixed. When fixing, it is only necessary to squeeze the cylindrical camera mechanism along the gap between the two semi-arc clamping blocks at the upper end of the base, and the moving blocks connected to the semi-arc clamping blocks slide away from each other in the assembly groove, and at the same time, the moving blocks squeeze the first spring in the assembly groove. When the camera mechanism enters between the two semi-arc clamping blocks, the first spring simultaneously pushes the two moving blocks to slide close to each other, and the semi-arc clamping blocks on the moving blocks can clamp and fix them, thereby effectively avoiding the problem of the camera mechanism being damaged by collision when the crack width meter body is operated with both hands.

[0014] Second, when assembling the clamping mechanism on the crack width gauge body, it is only necessary to insert the base of the clamping mechanism into the mounting seat. During the insertion process, the insertion end of the base is squeezed along the inclined surface of the block at the upper end of the mounting seat, so that the movable plate connected to the block slides in the mounting groove and actuates the second spring. When the base is inserted into the mounting seat, the position of the slot corresponds to the position of the card-in end of the block, and then the second spring resets and pushes the block connected to the movable plate into it to be fixed. When disassembling, it is only necessary to press the movable plate down through the shift block to separate the movable plate from the card slot to the card slot. At this time, the base can be pushed out horizontally along the slot notch to complete the disassembly, so that the clamping mechanism can be easily disassembled and assembled.
