Description

Technical Field

[0001] This utility model relates to the field of magnetic suction feeler gauges for gaps in building steel structures, and in particular to a magnetic suction feeler gauge for gaps in building steel structures. Background Technology

[0002] Currently, gap inspection is a crucial step in the construction and acceptance of steel structures. However, traditional feeler gauge technology presents significant inconveniences, especially at painted or complex-shaped steel structure joints. Operators typically need to manually and precisely insert the feeler gauge into the gap to be tested. This is not only cumbersome but also prone to dropping at heights or in poorly positioned locations, impacting both inspection efficiency and safety.

[0003] Although several technologies have been developed to optimize feeler gauges, such as using extendable structures to accommodate different gap depths or adding cushioning components to avoid interference with measurements, these improvements still do not solve the fundamental problem of requiring precise hand-held placement of feeler gauges at the initial stage of measurement. Furthermore, in scenarios requiring temporary marking or positioning, existing feeler gauges generally lack reliable fixing methods and still heavily rely on the operator's hand stability and experience.

[0004] An existing magnetic feeler gauge for gaps in building steel structures features a magnetic feeler gauge sensing mechanism, along with an anti-detachment mechanism and a fixing mechanism. When the magnetic feeler gauge is inserted into the gap, its inner end rotates and touches the sensor, transmitting the information to the display processor to calculate the corresponding feeler gauge size, thus displaying the specific gap dimension. It is fixed to the upper part of the building steel structure in the gap by magnetic magnets at both ends and a rotatable and retractable suction plate, ensuring the overall structure is firm and stable. When the work is finished, the feeler gauge is pulled out, the sliding pad is slid, and the feeler gauge is rotated back and placed in the groove at the lower end of the main body, where it is fixed by a spring pressure relief plate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a magnetic feeler gauge for gaps in building steel structures.

[0006] This utility model is achieved by the following technical solution: a magnetic feeler gauge for gaps in building steel structures, including a feeler gauge mechanism, an anti-detachment mechanism and a fixing mechanism. The lower end of the feeler gauge mechanism is fixedly connected to the anti-detachment mechanism, and the outer side of the feeler gauge mechanism is fixedly connected to the fixing mechanism. The feeler gauge mechanism includes a magnetic feeler gauge. A threaded post is fixedly connected to the inner side of the magnetic feeler gauge, and a nut is threadedly connected to the outer wall of the threaded post. A sensor is fixedly connected to the upper end of the magnetic feeler gauge, and a cable is fixedly connected to the upper surface of the sensor. A retainer is fixedly connected to the lower end of the cable, and a fixing base is fixedly connected to the outer wall of the cable. A receiver is fixedly connected to the left end of the cable, and a display screen is fixedly connected to the left end of the receiver.

[0007] The above technical solution involves setting up a magnetic feeler gauge sensing mechanism, along with an anti-detachment mechanism and a fixing mechanism. When the magnetic feeler gauge is inserted into the gap, its inner end rotates and touches the sensor, transmitting the information to the display processor and calculating the corresponding feeler gauge size, thereby displaying the specific gap size. It is then fixed to the upper steel structure of the gap by magnetic magnets at both ends and a rotatable and retractable suction plate, ensuring the overall structure is firm and stable. When the work is finished, the feeler gauge is pulled out, the sliding pad is slid, and the feeler gauge is rotated back and placed in the groove at the lower end of the main body, where it is fixed by a spring pressure relief plate.

[0008] As a further improvement to the above solution, the anti-detachment mechanism includes a sliding plate, a sliding column slidably connected to the inner side of the sliding plate, a telescopic rod rotatably connected to the outer wall of the sliding column, a pad fixedly connected to the lower end of the telescopic rod, a spring fixedly connected to the upper surface of the pad, and a pressure relief plate fixedly connected to the upper surface of the spring.

[0009] With the above technical solution, a spring pressure relief plate is set up. When the work is finished and the magnetic feeler gauge is rotated and retracted, the feeler gauge is placed on the upper part of the pressure relief plate. Due to the spring force in the opposite direction of the lower spring, which counteracts the gravitational potential energy of the feeler gauge, the feeler gauge can be stably held on the upper part of the plate, making it easy to carry later.

[0010] As a further improvement to the above solution, the fixing mechanism includes a main body, with magnetic magnets fixedly connected to the left and right sides of the main body, a fixed shaft fixedly connected to the outer wall of the main body, a rotating rod rotatably connected to the upper end of the fixed shaft, a telescopic rod II fixedly connected to the right end of the rotating rod, and an air suction plate fixedly connected to the right end of the telescopic rod II.

[0011] With the above technical solution, since the work is carried out inside the steel structure of the building, a magnetic suction cup and an air suction plate are set up. The magnetic field and air pressure difference can be used to firmly fix the main structure of the front end of the feeler gauge inside the steel structure, which facilitates subsequent work by the workers.

[0012] As a further improvement to the above solution, a circular roller is fixedly connected to the inner side of the sliding column, which slides within the sliding groove plate, and two fixed rings are fixedly connected to its outer end to form a rotating groove.

[0013] With the above technical solution, the circular roller inside the sliding column can roll in the sliding groove plate but will not slip out. The fixing ring is used to limit the displacement of the telescopic rod and prevent the telescopic rod from sliding out of the surface of the sliding column.

[0014] As a further improvement to the above solution, when the magnetic feeler gauge rotates, its end inside the main body touches the sensor, and the sensor generates information and transmits it through a cable.

[0015] With the above technical solution, the sensor is set on the inner wall of the upper end of the groove of the main body, located at the top of the inner end of the feeler gauge when it rotates, which makes it easier for the feeler gauge to touch the sensor and transmit information when it rotates.

[0016] As a further improvement to the above solution, two fixed shaft assemblies are provided, and the two fixed shaft assemblies are fixedly connected on the upper and lower outer walls of the main body.

[0017] By using the above technical solution, two fixed shaft assemblies are set up to form a four-position fixing assembly with the magnetic magnet. This allows for flexible adaptation to different environmental terrains within the building steel structure, enabling the entire feeler gauge structure to be fixed in any environment.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a magnetic feeler gauge sensor assembly. When a magnetic feeler gauge is placed inside a structural gap, its inner end rotates and touches the sensor located at its upper end. The sensor transmits the information to a display screen via a cable, showing the feeler gauge size and calculating the specific value.

[0019] This utility model uses a magnetic magnet fixing component. When the magnetic feeler gauge is fixed in the gap, its upper structure is fixed by the magnetic magnets at both ends, which prevents the structure from being unstable. The air suction plate at the lower end of the telescopic rod connected to the fixing shaft is attracted to the attachment surface, thus providing double fixation. This frees up the workers' hands.
