[0027] The following is a further description of a concrete crack extension depth detection device of the utility model in conjunction with the accompanying drawings and specific embodiments.
[0028] like Figures 1 to 9As shown, a concrete crack extension depth detection device includes a detector body 14, a gripping long rod 9, a handle 10, a second support plate 13, a first support plate 12, a support long plate 17 and a second support long rod 18. A display screen is fixedly installed on the front side of the detector body 14, a power block is fixedly installed inside the detector body 14, a wire body 15 is fixedly connected to the top of the detector body 14, one end of the wire body 15 is fixedly connected to the detection head body 11, the front side of the second support plate 13 is fixedly installed on the rear side of the detector body 14, the front side of the first support plate 12 is fixedly connected to the connecting plate 19, the front side of the connecting plate 19 is fixedly connected to the limiting plate 20, a plurality of limiting long grooves 21 are provided on the outer surface of the limiting plate 20, a spring 24, a first limiting vertical plate 23 and a second limiting vertical plate 26 are fixedly connected to the top of the supporting long plate 17, the first limiting vertical plate 23 is movably connected to the limiting long groove 21, and the second limiting vertical plate 26 is fixedly connected to the top of the supporting long plate 17. The left and right sides of the top ends of 26 are fixedly connected to the limit rod 25, and the bottom of the second support rod 18 is provided with a support groove 22. Through the arrangement of the detector body 14, the wire body 15 and the detection head body 11, the device can detect the extension depth of concrete cracks. Through the arrangement of the holding rod 9, the handle 10, the first rotating assembly, the second rotating assembly, the first limit assembly and the support assembly, the first rotating assembly and the second rotating assembly can both rotate the detector body 14, so that the first limit assembly can limit the first rotating assembly, and the support assembly can support the first limit assembly. When the device needs to change the use angle, the device can avoid changing the use angle by rotating the wrist of the user and causing the user's wrist to keep a constant posture, so that the user can avoid feeling strenuous due to keeping the wrist in a constant posture, and the device can avoid increasing the difficulty of use due to making the user feel strenuous.
[0029] Before the device is not used, the first limiting plate 23 is located in a limiting long groove 21, and the screw rod 6 is threadedly connected to a thread groove 3. When the device needs to be used to detect the extension depth of concrete cracks, when the device needs to change the use angle, the handle 10 is pulled in the direction away from the second support long rod 18, so that the support long plate 17 moves in the direction away from the second support long rod 18, so that the spring 24 is stretched in the direction away from the second support long rod 18, so that the limiting long rod 25 and the second limiting plate 26 both slide along the second support long rod 18, so that the first limiting plate 23 slides along a limiting long groove 21, the second support plate 13 and the second support long rod 18 respectively. When the handle 10 is pulled in the direction away from the second support long rod 18 to the maximum distance, the first limiting plate 23 is disconnected from the limiting long groove 21 and one end of the first limiting plate 23 is located inside the second support plate 13, keeping the handle 10 pulled to the maximum The distance between the two ends remains unchanged, the detector body 14 is rotated, the second support plate 13 is rotated along the first support plate 12, the connecting plate 19 and the limit plate 20 respectively, the second support rod 18 is rotated, and the angle of the detector body 14 is changed. When the angle changed by the detector body 14 is not the required angle, and when the first limit vertical plate 23 corresponds to the other limit long groove 21, the handle 10 is released, and the spring 24 changes from a stretched state to a compressed state in the direction close to the second support long rod 18, so that the first limit vertical plate 23 enters the other limit long groove 21. At this time, the device can change the use angle.

A display screen is fixedly installed on the front side of the detector body 14, a power block is fixedly installed inside the detector body 14, a wire body 15 is fixedly connected to the top of the detector body 14, and one end of the wire body 15 is fixedly connected to the detection head body 11. A supporting vertical rod 2 is slidably installed on the outer surface of the positioning long plate 8. The left side and the right side of the bottom end of the supporting vertical rod 2 are fixedly connected to the limiting vertical rod 16. A plurality of threaded grooves 3 are opened on the left side of the supporting vertical rod 2. A holding column 1 is fixedly connected to the top of the supporting vertical rod 2. The door-shaped long rod 4 is fixedly connected to the positioning long plate 8.

The tops of the two curved vertical plates 7 are jointly fixedly connected to the first supporting The long rod 5, the right side of the first supporting long rod 5 is fixedly installed on the left side of the gate-shaped long rod 4, the first supporting long rod 5 is slidably connected to the supporting vertical rod 2, the internal thread of the first supporting long rod 5 is connected with a screw rod 6, and the screw rod 6 is threadedly connected to the thread groove 3. Through the setting of the first operating range adjustment component, the second operating range adjustment component and the second limiting component, the first operating range adjustment component and the second operating range adjustment component can both adjust the operating range of the detection head main body 11, and the second limiting component can limit the first operating range adjustment component. When using this device to detect the extension depth of concrete cracks, when this device needs to adjust the operating range of the detection head operated by the user, this device can adjust the operating range of the detection head operated by the user, so that this device can avoid increasing the difficulty of operation due to the inability to adjust the operating range of the detection head operated by the user.
[0031] During use, after the device changes its use angle, when the device needs to adjust the operating range of the detection head operated by the user, the screw rod 6 is rotated to disconnect the screw rod 6 from a thread groove 3 and one end of the screw rod 6 is located inside the first supporting long rod 5, and the holding column 1 is moved along the vertical direction to make the supporting upright rod 2 slide along the first supporting long rod 5, the gate-shaped long rod 4 and the positioning long plate 8 respectively, so that the limiting upright rod 16 slides along the gate-shaped long rod 4, so that the distance between the detection head body 11 and the holding column 1 is changed, and the operating range of the detection head body 11 operated by the user through the holding column 1 is changed. When the distance between the detection head body 11 and the holding column 1 is the required distance, when the operating range of the detection head body 11 operated by the user through the holding column 1 is not the required range, and when the screw rod 6 corresponds to another thread groove 3, the screw rod 6 is rotated in the opposite direction to make the screw rod 6 threadedly connected to the other thread groove 3. When the device can adjust the operating range of the detection head operated by the user, during this process, when the device is used to detect the extension depth of concrete cracks, when the device needs to adjust the operating range of the detection head operated by the user, the device can adjust the operating range of the detection head operated by the user, so that the device can avoid increasing the difficulty of operation due to the inability to adjust the operating range of the detection head operated by the user. After the device adjusts the operating range of the detection head operated by the user, the device is started through the touch screen and the power block, and the user holds the holding long rod 9 with one hand and the holding column 1 with the other hand, moves the holding column 1, and aligns one end of the detection head body 11 with the concrete crack and moves along the concrete crack.
