As shown in fig. 1, a distance measuring device includes a detecting frame 1 for fixing and installing and an infrared distance sensor 4 for measuring distance. When the detection frame body 1 is directly installed and fixed, the infrared distance sensor 4 can be directly utilized to measure the distance. Wherein, the detection frame body 1 is rotatably connected with a cross connecting frame 5 which does upward or downward swinging motion. The infrared distance sensor 4 is rotatably connected with the cross connecting frame 5 so as to drive the infrared distance sensor 4 to swing when the cross connecting frame 5 swings upwards or downwards. It should be mentioned that a swing mechanism 6 is provided on the detection frame body 1. The swinging mechanism 6 is used for driving the infrared distance sensor 4 to do swinging movement towards the left or the right and/or to do swinging movement towards the upper or the lower. Meanwhile, a damping unit is arranged on the swinging mechanism 6, and when the swinging mechanism 6 drives the infrared distance sensor 4 to swing downwards, the damping unit is stressed. Therefore, after the swinging mechanism 6 drives the cross connecting frame 5 to do upward or downward swinging motion and the infrared distance sensor 4 on the cross connecting frame 5 to do rightward or upward swinging motion, the infrared distance sensor 4 is adjusted to a horizontal plane before distance measurement is carried out, so that the accuracy and the measurement efficiency of a measurement result are improved; correspondingly, the damping unit is stressed when the infrared distance sensor 4 swings downwards, so that the infrared distance sensor 4 is prevented from swinging downwards, the angle adjustment difficulty of the infrared distance sensor 4 is effectively reduced, and the distance measurement efficiency is improved.

Correspondingly, the output shaft of the swing motor 61 is fixedly connected with the swing adapter 63 through the swing arm penetrating through the swing arc-shaped groove 12, so that when the swing motor 61 operates, the output shaft drives the swing arm to rotate and drives the swing adapter 63 to rotate, and further the angle adjustment of the infrared distance sensor 4 is realized. Wherein, the fixed end of the swing telescopic arm 62 is hinged with the swing adapter 63, and the movable end is used for being rotatably connected with the infrared distance sensor 4. Therefore, when the swing mechanism 6 operates and drives the infrared distance sensor 4 to perform swinging movement towards the left or the right, the swing motor 61 is started and enables the swing arm to rotate in the swing arc-shaped groove 12, and then the swing telescopic arm 62 and the infrared distance sensor 4 are driven to perform synchronous swinging movement towards the left or the right; when the swing telescopic arm 62 is operated, the infrared distance sensor 4 will make an upward or downward swing motion with the horizontal part 51 as a shaft under the action of the swing telescopic arm 62, thereby realizing an effect of effectively driving the infrared distance sensor 4 to swing and adjust.

It should be noted that, as shown in fig. 3, the upper end outer side of the semicircular arc bracket 53 is provided with a hinge portion 531.

Therefore, when the connecting rotary column 623 performs a rotary motion relative to the damping plate 632, the abutment arm 626 connected to the rotary arm 624 performs the same rotary motion relative to the damping plate 632, so as to achieve the purpose of effectively connecting the abutment arm 626. When the abutting arm 626 abuts against the outer peripheral side wall of the ratchet wheel 64, the torsion spring limiting abutting piece 627 applies an acting force towards the ratchet wheel 64 to the abutting arm 626, so that the abutting arm 626 and the ratchet wheel 64 are always in an effective contact state, and the purpose of effective horizontal adjustment of the infrared distance sensor 4 is achieved.

Wherein, it is fixed to detect the direct mount of being convenient for of support body 1 to carry out effectual detection to horizontal distance through infrared distance sensor 4, and when detecting support body 1 and stand 2 installation fixed, install the rigidity that can accomplish detection support body 1 through stand 2's fixed waist groove 21. Meanwhile, after the T-shaped inserting groove 311 is matched with the inserting part 22, the U-shaped groove 32 of the bottom bracket 3 is used for inserting the plate-shaped object and then the plate-shaped object is installed and fixed by the fixing plug-in unit 33, so that the purpose of effective installation and fixation can be achieved, and the use difficulty of the distance measuring device is remarkably reduced.

In conclusion, the upright post 2 is fixed through the bottom bracket 3, and the detection frame body 1 is fixed through the upright post 2, so that the mounting and fixing difficulty of the detection frame body 1 is remarkably reduced, and the mounting and fixing flexibility of the detection frame body 1 is improved; meanwhile, the infrared distance sensor 4 is effectively driven to swing leftwards or rightwards through the cooperation of the swing motor 61 and the vertical part 52 of the cross connecting frame 5; and through the cooperation of the swing telescopic arm 62 and the horizontal part 51 of the cross connecting frame 5, the infrared distance sensor 4 is effectively driven to do upward or downward swing motion, so that after the distance measuring device is effectively installed and fixed, the horizontal state of the infrared distance sensor 4 is rapidly adjusted by combining the horizontal sensor and the swing mechanism 6, and the distance measuring device has the effects of improving the distance measuring precision and efficiency.
