Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a steel bar detector. Background Art

[0002] A steel bar detector is a professional instrument used to detect the position, distribution, diameter and cover thickness of steel bars in concrete structures. It is mainly applied to concrete structure projects such as bridges, tunnels and walls to ensure the project quality and safety.

[0003] The steel bars in a building are often distributed in the foundation, walls and ceiling. When detecting data such as the position and quantity of steel bars, it is necessary to lift or even hold up the detector for detection, and there may be a situation where the detector slips off due to a slippery hand. Therefore, a steel bar detector is needed for detection. For example, in the prior art, the Chinese Patent Publication No. "CN214201801U" discloses a steel bar scanner, which relates to the technical field of engineering cost measurement tools. It includes a scanner body, a display screen, control buttons and a measurement sensor arranged in the scanner body. A moving roller and a hand-held handle are arranged on the scanner body. One end of the scanner body close to the hand-held handle is provided with an anti-drop rope. One end of the anti-drop rope is fixed to the scanner body, a buffer is fixed on the anti-drop rope, and the other end of the anti-drop rope is used to be sleeved on the human hand. This application has the effect of reducing the probability of damage caused by the collision of the steel bar scanner.

[0004] In specific operations, the detector body and the hand protection ring are connected by a spring pull rope. The telescopic action of the spring pull rope is used to prevent the detector from slipping out of the hand. However, it is not convenient to disassemble and replace the spring pull rope with both the detector body and the hand protection ring. When the spring pull rope ages and its elasticity decreases after long-term use, or when the hand protection ring is damaged, it is not convenient to replace and affects normal use, or the overall replacement results in a relatively high replacement cost. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art that it is not convenient to disassemble and replace the spring pull rope with both the detector body and the hand protection ring, and a steel bar detector is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-5 , a steel bar detector, including an anti-slip component 2 provided on the detector body 1, sliding members 11 are provided on both sides of the detector body 1, and a handle 3 and a display screen 4 are provided on the top, and the anti-slip component 2 is also provided on the top of the detector body 1, and the anti-slip component 2 includes an anti-slip rope 21;

[0023] Among them, one end of the anti-slip rope 21 is fixed to the detector body 1 through a fixing component 5, and the other end is detachably connected to a tensioning member 22, and the tensioning member 22 is sleeved on the human wrist.

[0024] It should be added that the tensioning member 22 is an elastic telescopic ring made of nylon material, sleeved on the human wrist, and connected to the detector body 1 through the anti-slip rope 21 to prevent the situation of dropping off;

[0025] Among them, the sliding member 11 is a pulley, and at least one pair of sliding members 11 are respectively provided on both sides of the detector body 1. One is used to support the detector body 1 to avoid complete occlusion between the sensor at the bottom of the detector body 1 and the wall surface, which affects the detection, and the other is to facilitate the movement of the detector body 1;

[0026] In addition, the handle 3 is provided with a replaceable lithium battery, and a control panel is also provided on its side. The lithium battery supplies power to the control panel, the sensor, and the display screen 4, enabling the sensor to feed back the monitoring data to the display screen 4.

[0027] Furthermore, the fixing component 5 includes a plugging part 51 and a docking part 52. A sliding groove 12 is formed at the top of the detector body 1. The plugging part 51 is fixed in the sliding groove 12, and a plugging groove 511 is provided at its free end. The docking part 52 is slidably connected in the sliding groove 12 through a spring 53, and a docking block 521 is provided at its free end. The docking block 521 is engaged with the plugging groove 511.

[0028] It is worth mentioning that both the plugging part 51 and the docking part 52 are cylindrical structures and have the same diameter. The advantage of the docking block 521 being engaged with the plugging groove 511 is to prevent the annular part 24 from disengaging from the contact gap between the docking part 52 and the plugging part 51.

[0029] In addition, both ends of the spring 53 are respectively fixed to the sliding groove 12 and the side surface of the docking part 52.

[0030] Still further, an unlocking rod 54 is included. A relief groove 522 is provided on one side of the end of the docking part 52, and a guiding part 523 is provided in the relief groove 522. The top of the unlocking rod 54 has a pressing part 541, and a guiding inclined groove 542 is provided at its bottom. The unlocking rod 54 is arranged in the relief groove 522, and the guiding inclined groove 542 is slidably connected with the guiding part 523.

[0031] Specifically, the guiding inclined groove 542 is an inclined groove. The top of this inclined groove is close to the spring 53, and the bottom is close to the plugging part 51. The purpose is that when the unlocking rod 54 is pressed, the unlocking rod 54 moves downward and drives the docking part 52 to move inward by using the guiding inclined groove 542. Among them, the relief groove 522 is used to help the docking part 52 avoid the unlocking rod 54 and prevent jamming during movement. Of course, when the docking part 52 is disengaged from the plugging part 51, the annular part 24 can be disassembled and assembled.

[0032] After releasing the unlocking rod 54, under the supporting action of the spring 53, the docking part 52 resets and pushes the unlocking rod 54 to rise.

[0033] More specifically, the middle part of the anti - detachment rope 21 is spirally coiled to form a telescopic part 23. One end has an annular part 24, and the other end has a fixing part 25. Among them, the plugging part 51 and the docking part 52 are docked and fix the annular part 24, and the annular part 24 is sleeved on the periphery of the plugging part 51 or the docking part 52.

[0034] It should be noted that the anti-drop rope 21 is specifically a spring pull rope used to connect a signature pen in public places to prevent the signature pen from being lost. The pull rope is made of a ductile material such as stainless steel or carbon steel, and is coated with plastic, rubber or other materials on the periphery. The spring pull rope can automatically retract to its original length after being stretched.

[0035] The inner diameter of the annular portion 24 is matched with the outer wall diameters of the plug-in portion 51 and the docking portion 52 .

[0036] In general, a connecting portion 26 is fixed to the inner side of the elastic member 22 , and the midpoint of the connecting portion 26 passes through the elastic member 22 to form a through hole 261 .

[0037] Specifically, the elastic member 22 is made of nylon material, and the connecting portion 26 can be fixed by bonding. A flexible pad can also be provided on the inner wall of the elastic member 22 to prevent the connecting portion 26 from contacting the human wrist. Of course, the through hole 261 also needs to pass through the flexible pad.

[0038] Finally, one end of the fixed portion 25 connected to the anti-offset rope 21 has a limiting plate 251, and the other end thereof is penetrated by the through hole 261 and is provided with a supporting portion 252, wherein the supporting portion 252 is provided with a deformation groove 253 located on the center line, and the deformation groove 253 extends to the middle of the fixed portion 25, wherein the supporting portion 252 abuts against the connecting portion 26 and cooperates with the limiting plate 251 to be fixed to the connecting portion 26.

[0039] It should be added that the fixing portion 25 is preferably made of a deformable material such as rubber or plastic, wherein a guide slope is provided on the side of the abutting portion 252 away from the connecting portion 26, and the guide slope is used to reduce friction when the fixing portion 25 passes through the through hole 261;

[0040] The abutting portion 252 abuts against one side of the connecting portion 26 , and the limiting plate 251 abuts against the other side of the connecting portion 26 via the elastic member 22 , thereby preventing the fixing portion 25 from being separated.

[0041] Working method: When working, the elastic member 22 is set on the human wrist, and the detector body 1 is held by the handle 3 to detect the steel bars in the building to prevent the detector from slipping out of the hand;

[0042] When the anti-slip rope 21 needs to be replaced after long-term use, the unlocking rod 54 is pressed, and the unlocking rod 54 moves downward to drive the docking part 52 to move inward by utilizing the guide bevel 542, so that the docking part 52 is separated from the plug-in part 51, and the anti-slip rope 21 is replaced. Similarly, after loosening the unlocking rod 54, the docking part 52 is reset under the support of the spring 53, and the unlocking rod 54 is pushed up.

[0043] Moreover, when the tightening member 22 needs to be replaced, the fixing portion 25 deforms through the deformation groove 253, and after the abutting portion 252 disengages from the through hole 261, it can be replaced.

[0044] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
