[0002] In concrete structures, the quality of steel bars is one of the main factors affecting the quality of engineering structures. Cases of quality accidents due to improper configuration of steel bars in concrete or poor material quality are not uncommon. In the process of renovation, maintenance and reinforcement of engineering structures, the engineering structures must first be inspected and identified. In this process, a steel bar scanner will be used. The steel bar scanner is mainly used to detect the distribution, diameter, direction of steel bars in engineering building concrete structures, and the thickness of concrete protective layer.

[0003] The patent with authorization announcement number CN214149432U discloses a steel bar detector, which can scan different wall surfaces and can move the steel bar scanner body at different angles on the wall surface by using an adjustment component and a roller.

[0004] However, the detector body is inconvenient to carry and needs to be carried with the aid of a detection box, which results in poor flexibility during use. Utility Model Content

[0005] In view of this, the utility model provides a portable steel bar detector for construction engineering quality inspection, which can quickly install and disassemble the detector body in a protective shell, thereby protecting the detector body and making it convenient to carry.

[0009] Preferably, a guide tube is fixedly provided on the support plate, a guide rod is slidably mounted on the guide tube, and the guide rod is fixedly connected to the protective shell.

[0010] During use of the above technical solution: by canceling the limit of the detector body by the limit mechanism, under the action of the second elastic component, the detector body is pushed up along the protective shell by the support plate, so that the detector body can be easily taken out.

[0043] The pop-up mechanism 8 includes a support plate 801 movably mounted in the protective shell 1 , and a second elastic component 804 is disposed between the support plate 801 and the protective shell 1 .

[0044] A guide tube 802 is fixedly provided on the support plate 801 , a guide rod 803 is slidably mounted on the guide tube 802 , and the guide rod 803 is fixedly connected to the protection shell 1 .

[0046] In actual operation: the detector body 9 is placed in the protective shell 1, and the detector body 9 is pressed down. The detector body 9 squeezes the reset spring through the support plate 801, so that the reset spring generates an upward rebound force. At the same time, the guide tube 802 moves along the guide rod 803, and the movement of the detector body 9 is limited by the limiting mechanism 7. The limit of the detector body 9 by the limiting mechanism 7 is canceled. Under the action of the second elastic component 804, the detector body 9 is pushed to bounce up along the protective shell 1 through the support plate 801.

[0047] The limiting mechanism 7 includes a limiting cavity 701 fixedly mounted on the protective shell 1, the limiting cavity 701 is fixedly and sealedly connected to the first through hole 6, a first piston 702 is fixedly arranged on the limiting block 706, the first piston 702 is slidably mounted in the limiting cavity 701, and a first elastic component 703 is arranged between the limiting cavity 701 and the first piston 702.

[0049] A first annular frame 708 is fixedly disposed in the limiting cavity 701 . The first annular frame 708 corresponds to the first piston 702 . A connecting rod 704 is disposed between the first piston 702 and the limiting block 706 . The connecting rod 704 slides through the first annular frame 708 .

[0051] Specifically: the first elastic component 703 is a limit spring, the limit block 706 is a cuboid, the limit mechanism 7 is in two groups, and the two groups of limit mechanisms 7 are symmetrically concealed on the protective shell 1.

[0052] In actual operation: the detector body 9 is moved downward along the protective shell 1, the detector body 9 contacts the arc surface 707 of the limit block 706, and the limit block 706 is pushed to move along the first through hole 6 in the direction close to the first elastic component 703, and at the same time, the first elastic component 703 is squeezed, so that the first elastic component 703 generates a rebound force, and the detector body 9 is installed in the protective shell 1. At this time, under the action of the first elastic component 703, the limit block 706 is pushed to move along the first through hole 6, limiting the upward movement of the detector body 9; Example

[0053] Based on the first embodiment, Figures 6 to 9As shown, a piston cavity 711 is fixedly provided on the protective shell 1, and the piston cavity 711 is fixedly and sealedly connected with the limit cavity 701 through a connecting pipe 710. A second piston 705 is fixedly provided on the connecting rod 704, and the second piston 705 is slidingly and sealingly installed in the first through hole 6. A third piston 713 is slidingly and sealingly installed in the piston cavity 711. The third piston 713, the piston cavity 711, the connecting pipe 710, the limit cavity 701, the first piston 702 and the second piston 705 form a sealed cavity. Operating the third piston 713 to squeeze the gas in the sealed cavity will push the first piston 702 to move along the detection cavity in the direction away from the protective shell 1, and will drive the limit block 706 to retract into the first through hole 6.

[0054] The limiting cavity 701 is provided with a second annular frame 709 , the connecting rod 704 slides through the second annular frame 709 , and the second piston 705 displaces the second annular frame 709 to be close to one end of the protective shell 1 .

[0055] Specifically: a piston rod 712 is fixedly provided on the third piston 713, a second through hole is provided on the piston cavity 711, and the piston rod 712 moves through the second through hole. In a static state, the elastic force of the first elastic component 703 is greater than the pressure of the gas in the sealing cavity, and the limit block 706 extends out of the first through hole 6, which will limit the movement of the detector body 9.

[0056] In actual operation: by pressing the piston rod 712, the third piston 713 is pushed to move along the piston cavity 711 toward the protective shell 1. The third piston 713 squeezes the gas in the sealed cavity, and the gas pressure in the sealed cavity increases, pushing the first piston 702 to move along the detection cavity away from the protective shell 1, which will drive the limit block 706 to retract into the first through hole 6, and quickly remove the limit of the limit block 706 on the detector body 9, making it convenient to remove the detector body 9. When the pressing force on the piston rod 712 is removed, the third piston 713 and the limit block 706 are pushed to reset under the reaction force of the first elastic component 703.

[0057] The working principle of the utility model is as follows: two straps 4 are wrapped around the waist of the user and fixed by Velcro 5, and the buckle 3 is inserted into the waist belt of the user;

[0058] The detector body 9 is placed in the protective shell 1, and the detector body 9 is pressed down. The detector body 9 squeezes the reset spring through the support plate 801, so that the reset spring generates an upward rebound force. At the same time, the guide tube 802 moves along the guide rod 803, and the movement of the detector body 9 is limited by the limit mechanism 7. The limit of the detector body 9 by the limit mechanism 7 is cancelled. Under the action of the second elastic component 804, the detector body 9 is pushed to bounce up along the protective shell 1 through the support plate 801;

[0059] Move the detector body 9 downward along the protective shell 1, the detector body 9 contacts the arc surface 707 of the limit block 706, and pushes the limit block 706 to move along the first through hole 6 in the direction close to the first elastic component 703, and at the same time squeezes the first elastic component 703, so that the first elastic component 703 generates a rebound force, and the detector body 9 is installed in the protective shell 1. At this time, under the action of the first elastic component 703, the limit block 706 is pushed to move along the first through hole 6, limiting the upward movement of the detector body 9.
