Description

Technical Field

[0001] This utility model relates to the field of target technology, and in particular to an automatically adjustable target for non-contact measurement. Background Technology

[0002] With the continuous development of modern building technology, building structures are becoming increasingly complex and diverse, and the requirements for building quality and safety are also getting higher and higher. Cracks are one of the common defects in building structures, and their accurate detection is crucial for assessing the stability and durability of building structures. Traditional contact measurement methods can damage the surface of building structures when detecting cracks, and the measurement accuracy and efficiency are limited, making it difficult to meet the needs of high-quality testing in modern buildings. Therefore, a more advanced, accurate and non-contact measurement method and equipment are needed.

[0003] A search revealed Chinese Patent Publication No. CN220708553U, which discloses a target device comprising: a target surface with a through hole at its center and concentric circles centered on the through hole; a rear cover connected to the target surface, with an installation space between them; a heat source partially or entirely contained within the through hole; and a temperature control component installed within the installation space for regulating the temperature of the heat source. This application features a simple and compact design with good heat dissipation, meeting the optical axis adjustment requirements of various infrared products. However, this invention fails to consider that if the target cannot be moved during building crack detection, not all cracks can be detected. Manually adjusting the target position results in low accuracy and cannot meet user needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatically adjustable target for non-contact measurement, aiming to improve the problem in the prior art that if the target cannot be moved, it will lead to the inability to detect all cracks, and the method of manually adjusting the target position is inaccurate and cannot meet the needs of users.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatically adjustable target for non-contact measurement, comprising an L-shaped plate, a motor fixedly connected to the left side of the inner wall of the L-shaped plate, a hollow column fixedly connected to the output end of the motor, an inclined groove formed on the outer wall of the hollow column, a pushing column slidably connected to the inner wall of the hollow column, sliders fixedly connected to the upper and lower ends of the outer wall of the pushing column, a sliding groove formed on the top right side of the L-shaped plate, a U-shaped plate slidably connected to the inner wall of the sliding groove, a mounting plate slidably connected to the inner wall of the U-shaped plate, a telescopic rod fixedly connected to the bottom of the inner wall of the U-shaped plate, and a rainproof mechanism provided on the top of the L-shaped plate to prevent the equipment from being wetted by rainwater.

[0006] Through the above technical solution: the motor is the power source of the entire device, responsible for providing the necessary power output; the inclined groove cleverly utilizes space, making the device more compact during operation; the slider ensures the stability and accuracy of the push column during movement; the U-shaped plate is slidably connected to the mounting plate, giving the device extremely high flexibility during operation; the telescopic rod allows the device to be height adjusted according to different usage needs; and the rainproof mechanism is designed to protect the equipment from rain damage, ensuring stable operation of the equipment under various weather conditions.

[0007] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:

[0011] A limiting plate is fixedly connected to the right side of the inner wall of the chute, and a target is fixedly connected to the front side of the mounting plate.

[0012] Through the above technical solution: the limiting plate prevents the U-shaped plate from exceeding the predetermined range during sliding, thus ensuring the safety of the device. The target not only increases the practicality of the device but also provides users with a clear target, making the operation more intuitive.

[0013] As a further description of the above technical solution:

[0014] A handle is fixedly connected to the top of the rotating column, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0015] Through the above technical solution, the anti-slip sleeve takes into account the user's grip comfort, so that there will be no fatigue even after long-term operation.

[0019] As a further description of the above technical solution:

[0020] The support plate has a weight-reducing groove in the middle, and the inner wall of the groove is slidably connected to the outer wall of the slider.

[0021] The above technical solution reduces the overall weight by using a weight-reducing groove, and the inclined groove is slidably connected to the slider, allowing the slider to move smoothly in the inclined groove, thereby achieving its function.

[0022] As a further description of the above technical solution:

[0023] A controller is fixedly connected to the left side of the L-shaped plate, and the controller is electrically connected to the motor.

[0024] Through the above technical solution: the controller is responsible for receiving instructions from the operator.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when the motor is started, it drives the hollow column to rotate, pushing the slider to slide along the inclined groove, causing the pushing column to move to the right. Subsequently, the pushing column pushes the U-shaped plate to move to the right along the sliding groove to the designated position. After the motor stops, the telescopic rod is started, and the telescopic rod pushes the mounting plate to slide upward along the U-shaped plate, which can remotely steer the target, realizing the up, down, left, and right movement of the target, so that the target can better receive signals and improve the accuracy of crack detection.

[0030] 2. In this utility model, when it rains, the side plate is pulled to block rainwater on both sides. After the side plate is pulled out, the spring column causes part of the baffle to spring into the top plate. Then, the rotating plate is pulled to make it rotate around the rotating column and fall on the baffle. The baffle supports the rotating column and blocks rainwater on the front side, thus protecting the equipment and preventing rainwater from wetting the equipment, causing damage to the equipment, and thus affecting the normal operation of the work.

[0047] Working principle: When motor 3 is started, it drives the hollow column 4 to rotate. During the rotation, the hollow column 4 pushes the slider 7, causing the slider 7 to slide along the inner wall of the inclined groove 5. This pushes the push column 6 to move to the right. The push column 6 then pushes the U-shaped plate 8 to move to the right along the inner wall of the sliding groove 9. When it reaches the designated position, motor 3 is stopped, and then the telescopic rod 10 is started. The telescopic rod 10 pushes the mounting plate 11 to slide upward along the inner wall of the U-shaped plate 8, which allows for remote control of the target 12. This enables the target 12 to move up, down, left, and right, allowing the target 12 to receive signals better and improving the accuracy of crack detection.

[0048] When it rains during the testing process, the side plates 204 are pulled to both sides to block the rainwater on both sides. After the side plates 204 are pulled out, the spring column 206 will push part of the baffle 202 out of the top plate 201. At this time, the rotating plate 205 is pulled, causing the rotating plate 205 to rotate around the outer wall of the rotating column 203 and finally fall on the top of the baffle 202. The baffle 202 will support the rotating column 203, thereby blocking the rainwater on the front side, thus protecting the equipment and preventing rainwater from wetting the equipment, causing damage, and affecting the normal operation of the work.
