[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-3 As shown, a device for detecting the number of steel bars in hydraulic concrete includes:

[0034] The sliding part 1, the cabin part 11 and the hand-held part 12 are integrated on the sliding part 1. The cabin part 11 is equipped with a circuit board, and the display 2 and the function editor 3 integrated on the circuit board are mounted on the upper surface of the cabin part 11. The sensor 4 electrically connected to the circuit board is mounted on the lower surface of the sliding part 1.

[0035] The outer frame 5, the sliding part 1 at the top corner of the sliding part 1 is slidably assembled in the groove opened at the inner corner of the outer frame 5, the inner wall of the outer frame 5 is symmetrically fixed with a limiting plate 51, and the contact surfaces of the limiting plate 51 and the sliding part 1 are provided with a neodymium magnet 52 that can be magnetically attracted.

[0036] Specifically, in this embodiment, the outer frame 5 is integrally designed with a crossbeam, and the sensor 4 is fixedly installed on the crossbeam. The crossbeam (fixed and cannot be moved) is distributed in close contact with the lower surface of the outer frame 5, while the detection end of the sensor 4 faces downward.

[0037] In use, sensor 4 is placed on the concrete surface and scans along a predetermined path or grid. Sensor 4 then emits electromagnetic signals, and the location and quantity of the reinforcing bars are identified by measuring the rebound signals. During the detection process, the data displayed on monitor 2 can be viewed in real time to understand the distribution of the reinforcing bars. The function editor 3 in this embodiment is used to start and stop the device, as well as to view predetermined functions such as historical records. Furthermore, in the above embodiment, a rechargeable battery is also fixedly installed inside the cabin 11. It can be directly powered by an external 220V AC mains power supply via a USB interface, and the entire battery status can be determined by the color change of a breathing light on the circuit board: green indicates fully charged, and red indicates charging.

[0038] Furthermore, the aforementioned electronic components and execution programs are all common technical knowledge to those skilled in the art, and therefore will not be described in detail.

[0039] In the above technology, the sliding part 1 and the outer frame 5 are used to form a cooperation, and the sliding part 1 can be stored and exposed by pulling the sliding part 1 out of the inner and outer sides of the outer frame 5.

[0040] The sliding part 1 is equipped with a display 2 and a function editor 3. The function editor 3 can control the sensor 4 to acquire detection data and display the number of steel bars on the display 2.

[0041] As a further embodiment of this utility model, a wheel groove 53 is provided on the outer side of the outer frame 5. The inner wall of the wheel groove 53 is an inclined surface 531, and through grooves 54 distributed on the inclined surface 531 are provided in the wheel groove 53. Furthermore, a slider 55 is slidably disposed in the through groove 54, and a guide wheel 6 is rotatably disposed on the slider 55. Moreover, and close to the upper surface of the outer frame 5, the end face of the guide wheel 6 is flush with the outer side of the outer frame 5.

[0042] Specifically, in combination Figure 3 As shown, and with Figure 3 With the indicated position as a reference, when the slider 55 moves upward, the guide wheel 6 is completely retracted into the wheel groove 53. When the slider 55 moves downward, as the slope of the inclined surface 531 increases, the guide wheel 6 extends out of the outer side of the wheel groove 53 and the bottom of the outer frame 5. At this time, the cabin part 11 and the handheld part 12 are also exposed to the top of the outer frame 5. At this time, the entire device can be used to detect the number of steel bars.

[0043] As a further embodiment of this utility model, a first connecting rod 70 is rotatably provided on the inner wall of the outer frame 5, and a shaft 701 is fixedly installed at the end of the first connecting rod 70. The shaft 701 passes through the slider 55 and extends into the guide wheel 6 for sliding.

[0044] Furthermore, a second connecting rod 71 is rotatably provided on the inner wall of the outer frame 5, and the end of the second connecting rod 71 is slidably disposed in the first waist groove 702 opened on the first connecting rod 70;

[0045] Furthermore, the second connecting rods 71 ​​located on the same outer frame 5 are distributed adjacently at one end.

[0046] Secondly, a lever 72 is rotatably provided on the inner wall of the outer frame 5. The lever 72 is divided into a first part and a second part with the rotatable connection point with the outer frame 5 as the origin.

[0047] The second waist groove 711 opened on the first part and the second connecting rod 71 is slidably connected;

[0048] The second part is a third waist groove that is slidably set on the side of the sliding part 1. The third waist groove is arranged in a horizontal direction.

[0049] Specifically, in the above embodiment, when the guide wheel 6 is fully retracted into the wheel groove 53, the cabin part 11 and the handheld part 12 are also retracted into the outer frame 5. At this time, the first connecting rod 70, the second connecting rod 71, and the lever 72 are as follows: Figure 2 The positions shown indicate the storage state. When needed, hold the handle 12 with one hand and press the outer frame 5 with the other, thus moving the handle 12 upwards. At this time, the first and second parts of the lever 72 are as follows... Figure 2 As shown by the dotted line, the second connecting rod 71 rotates in conjunction with the second waist groove 711, at which point the second connecting rod 71 is as follows: Figure 2 The dotted line shown rotates. At this time, the first connecting rod 70, in conjunction with the first waist groove 702, rotates as follows: Figure 2 The dotted line shown rotates and swings downward, causing the shaft 701 to slide towards the receiving cavity 100. At this time, the slider 55 moves downward, and as the slope of the inclined surface 531 increases, the guide wheel 6 extends out of the outer side of the receiving wheel groove 53 and the bottom of the outer frame 5. At this time, the cabin part 11 and the hand-held part 12 are also exposed to the top of the outer frame 5. At this time, the entire device can be used to detect the number of steel bars.

[0050] As another embodiment of the present invention, one end of the arc-shaped elastic member 8 is fixed to the inner wall of the through groove 54, while the other end abuts against the inner wall of the through groove 54, and the abutting position is distributed close to the lower surface of the outer frame 5.

[0051] The arc-shaped elastic element 8 abuts against the inner wall of the through groove 54 at one end, forming a receiving cavity 100 for locking the shaft 701 between the end of the through groove 54 and the other end of the through groove 54.

[0052] Specifically, in this embodiment, when the shaft 701 passes the arc-shaped elastic element 8, it will be limited within the receiving cavity 100. When the handheld part 12 does not apply a large downward force, the shaft 701 cannot pass the arc-shaped elastic element 8. By passing the arc-shaped elastic element 8 and locking, the state switching of the steel bar count detection device in concrete is stopped.

[0053] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
