Technical Field
[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a concrete crack observation instrument. Background Technology
[0002] A concrete crack monitoring instrument is a precision instrument used to monitor and measure changes in the width of cracks in concrete structures. It can accurately measure the width of concrete cracks by bringing a microscope camera or sensor into contact with the concrete surface to capture crack images, which are then displayed on a screen. The width of the crack is then measured using a built-in ruler or image analysis software, providing strong support for structural safety monitoring and quality inspection.
[0003] Existing concrete crack observation instruments require operators to hold a microscope camera in one hand and an image display in the other. When inspecting cracks of a certain height, having both hands occupied poses a risk, making it difficult to maintain stable support and balance, and increasing the risk of slipping or falling, leading to accidents. Furthermore, it is difficult to perform operations such as calibration, focus adjustment, and stretching on the image display while holding the image display, affecting work efficiency and observation quality.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0019] like Figures 1-3 As shown, a concrete crack observation instrument includes a chest plate 1 that is fastened to the chest via a chest strap 115. Two rocker arms 102 are symmetrically fixed to both ends of the chest plate 1. A neck strap 116 for hanging around the neck is fixedly connected to one side of the top of the chest plate 1. A square hole 101 is formed through the middle of the chest plate 1. A rotating plate 103 is rotatably connected to one side of the chest plate 1. A display 2 is movably placed on the top of the rotating plate 103. Spring pillars 110 are symmetrically and elastically assembled on one side of the chest plate 1 and the side of the rotating plate 103. One end of each of the two spring pillars 110 is fixedly connected to a clamping plate 111 for holding the display 2. A clamping plate 105 for holding the display 2 is provided on the outer side of one end of the rotating plate 103. A through opening for the clamping plate 105 is formed on the inner side of the rotating plate 103. The square hole 104 is movable and fitted. A screw 106 is rotatably connected to the middle of the clamping plate 105. The screw 106 is rotatably screwed to the rotating plate 103 through a thread at one end. Limiting rods 107 are fixedly connected to both ends of the clamping plate 105. The limiting rods 107 are slidably connected to the rotating plate 103. Protective plates 108 are symmetrically fixedly connected to both sides of the rotating plate 103. Support rods 112 are symmetrically rotatably connected to both ends of the rotating plate 103. Clips 109 for fitting and fixing the support rods 112 are fixedly connected to the outer side of the protective plate 108. Magnetic suction columns 114 are symmetrically fixedly connected to one side of the chest plate 1. A groove is opened at one end of the support rod 112 for magnetically fitting with the magnetic suction column 114. A through groove 113 is opened at the other end of the support rod 112 for movably fitting with the magnetic suction column 114.
[0020] According to the above structure, the chest plate 1 is looped around the chest with the chest strap 115, and the neck strap 116 is hung around the neck. The square hole 101 facilitates ventilation and sweat permeability. The rocker arm 102 is tilted outward to prevent the two ends of the chest plate 1 from rubbing against the skin on the chest. After rotating and lifting the rotating plate 103, the support rod 112 is rotated counterclockwise so that the groove at one end of the support rod 112 is engaged with the top of the magnetic column 114 and is attracted and fixed. At this time, the rotating plate 103 is horizontal and perpendicular to the chest plate 1. The display 2 is placed on the top of the rotating plate 103. Due to the angle limitation of the clamping plate 105 by the limiting rod 107, when the screw 106 is rotated, the screw 106 moves linearly through the screw connection with the rotating plate 103, and drives the clamping plate 105 to move synchronously. The clamping plate 105 and the clamping plate 211 clamp the display 2, and due to the elastic contraction of the spring column 110, it can... The position of the display 2 can be adjusted within a certain range to facilitate eye observation. After the observation work is completed, the display 2 can be removed, and the support rod 112 can be separated from the magnetic column 114. The support rod 112 can be rotated clockwise to fit into the clip 109 for fixation. The rotating plate 103 can be rotated to fit against the chest plate 1. At this time, the slot 113 and the magnetic column 114 are engaged, which can reduce the area occupied by the rotating plate 103 and other components. This utility model can fix the chest plate 1 in front of the operator's chest through the chest strap 115 and neck strap 116. The display 2 can be clamped and fixed to one side of the rotating plate 103 through the clamp 105 and clamp 2 111, thereby optimizing the allocation of limb resources, freeing up the function of one hand for easy gripping, improving the stability of the human body when working at height, and also facilitating the operation of the display 2, thus improving work efficiency.
[0021] The working principle of this utility model is as follows: The chest plate 1 is fitted onto the chest via the chest strap 115, and the neck strap 116 is hung around the neck. The square hole 101 facilitates ventilation and perspiration. The rocker arm 102 is tilted outwards to prevent the ends of the chest plate 1 from rubbing against the skin on the chest. After rotating and lifting the rotating plate 103, the support rod 112 is rotated counterclockwise, causing the groove at one end of the support rod 112 to engage and adhere to the top of the magnetic column 114. At this time, the rotating plate 103 is horizontal and perpendicular to the chest plate 1. The display 2 is placed on top of the rotating plate 103. Due to the angle limitation of the clamping plate 105 by the limiting rod 107, when the screw 106 is rotated, the screw 106, through its interaction with the rotating plate 103, causes the display 2 to be positioned. The screw connection of the movable plate 103 moves linearly, driving the clamping plate 105 to move synchronously. The clamping plate 105 and the clamping plate 111 clamp the display 2. Due to the elastic contraction of the spring column 110, the position of the display 2 can be adjusted within a certain range to facilitate eye observation. After the observation work is completed, the display 2 can be removed and the support rod 112 can be separated from the magnetic column 114. The support rod 112 is rotated clockwise to fit into the clamp 109 for fixation. The rotating plate 103 is rotated to fit against the chest plate 1. At this time, the through slot 113 is fitted with the magnetic column 114, which can reduce the area occupied by the rotating plate 103 and other components.
[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
