Description

Technical Field

[0001] The utility model relates to the technical field of crack detectors, in particular to a crack detector with an adjustment function. Background Art

[0002] Cracks in civil engineering refer to cracks that appear in buildings or other civil structures. Cracks may be caused by a variety of factors, such as foundation settlement, improper structural design, and poor quality of materials. The presence of cracks will affect the safety and stability of civil engineering structures and may cause damage or even collapse of the structure. Therefore, crack detection in civil engineering is very important, and a crack detector is needed to check for cracks.

[0003] Most existing crack detectors consist of a movable ruler and a measuring rod. Such measuring rods are too wide to measure small gaps, and such tools are prone to displacement when taken out of the gap, resulting in inaccurate measurements. Therefore, the present invention provides a crack detector with an adjustment function to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a crack detector with an adjustment function. To check the size of the gap, a folding plate is inserted into the gap. Small gaps can be measured through the stepped grooves on the folding plate. When the gap is too large, both the folding plate and the measuring plate are inserted into the gap, and the gap is measured by sliding the measuring plate to one side through the second vertical plate, which facilitates the measurement of the crack.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a crack detector with an adjustment function, comprising a frame, a folding plate, an outer plate and a measuring plate, wherein a moving block is slidably provided on the inner wall of the frame, an upper plate is fixedly provided on the upper end surface of the moving block, a fixed block is fixedly provided on the front side of one end surface of the upper plate, a tightening bolt is provided on the threaded sleeve on the inner wall of the fixed block, an embedded block is fixedly provided on the upper side of the middle of one end surface of the frame, and a stepped groove is provided on one side of the lower end surface of the folding plate;

When the gap is too large, both the folding plate and the measuring plate are inserted into the gap, and the gap is measured by sliding the measuring plate to one side through the second vertical plate, which is convenient for measuring cracks.

[0008] Furthermore, an embedding groove is provided at a middle position on the other end surface of the folding plate, and the embedding block is clamped and arranged on the inner wall of the embedding groove;

[0009] With the above technical solution, when the folding plate is folded and stored, the folding plate is folded upward and the embedded block is inserted into the embedded groove to fix the folding plate and prevent it from falling down by itself.

[0010] Furthermore, a lower block is hingedly provided on one side of the upper end surface of the folding plate, and the upper end surface of the lower block is fixedly provided on the lower end surface of the frame;

[0011] Through the above technical solution, a lower block is provided under the frame, and a folding plate is provided under the lower block. The folding plate is hingedly connected to the upper block through damping, so that the folding plate can be unfolded at different angles.

[0012] Furthermore, a first vertical plate is fixedly provided on the other side of the upper end surface of the frame, a groove is provided on one end surface of the shell, and the first vertical plate is provided on the inner wall of the groove;

[0014] Furthermore, an outer groove is provided at the lower middle portion of the front end surface of the fixing block, and the outer plate is slidably arranged on the inner wall of the outer groove;

[0015] Through the above technical solution, the outer plate on the frame slides inside the outer groove, making it convenient to view the measured data.

[0016] Furthermore, an inner groove is provided in the lower middle portion of the inner wall of the front side of the frame, an inner plate is fixedly provided between the outer plate and the movable block, and the inner plate is slidably provided on the inner wall of the inner groove;

[0017] Through the above technical solution, the outer plate is connected to the inner plate on the moving block, and the inner plate slides inside the inner groove, making it more convenient for the moving block to slide.

[0018] Furthermore, the measuring plate is hingedly arranged on the lower inner wall of the moving block, and a plurality of scales are fixedly arranged on the front end surface of the measuring plate;

[0019] With the above technical solution, the depth of the crack can be monitored by inserting the measuring plate into the crack through the scale on the measuring plate.

[0020] Furthermore, auxiliary grooves are provided on the upper sides of the front inner wall and the rear inner wall of the frame, and auxiliary blocks are fixedly provided on the upper sides of the front end face and the rear end face of the movable block, and the two auxiliary blocks are slidably provided on the inner walls of the two auxiliary grooves respectively;

[0021] Through the above technical solution, when the moving block slides inside the frame, the auxiliary block slides inside the auxiliary groove, so that the moving block moves more stably.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a crack detector with an adjustment function. When using the detector, the folding plate fixed at one end of the frame is flipped down and the folding plate is inserted into the crack. The width of small cracks can be measured through the stepped groove on the folding plate, making it more convenient to measure the width of small cracks. Moreover, by adjusting the folding plate to allow it to be stored, the crack depth can be measured through the measuring plate, making the detector more convenient to use.

[0024] 2. The utility model proposes a crack detector with an adjustment function. When measuring larger cracks, both the folding plate and the measuring plate are inserted into the crack. The crack is measured by pinching the sliding block of the second vertical plate to drive the measuring plate to slide, and then the clamping bolt is turned to fix it to avoid displacement when taking out the measuring plate. The measured value can be clearly viewed through the pointer on the outer plate, making crack measurement more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
