Description

Technical Field

[0001] This utility model relates to the field of smart gas meter technology, and in particular to a smart gas meter with a quick installation and disassembly structure. Background Technology

[0002] In the application scenarios of smart gas meters, the ease of installation and disassembly, structural stability, and safety have always been key concerns in the industry. Traditional smart gas meter installation typically relies on fasteners such as bolts and nuts to fix the meter to a bracket. This method has obvious technical drawbacks: Firstly, the installation process of bolts and nuts requires multiple tightening operations with the aid of tools, which is cumbersome and time-consuming, especially in batch installations or operations in confined spaces, resulting in low work efficiency. Secondly, during long-term use, factors such as pipeline vibration and environmental temperature differences can cause bolts and nuts to loosen, leading to displacement or even detachment of the gas meter. This not only affects the accuracy of metering data but may also cause safety hazards such as gas leaks. In addition, traditional installation structures lack effective designs to prevent unauthorized disassembly. Unauthorized personnel can easily disassemble the gas meter with common tools, which may lead to data tampering, equipment damage, or human error, seriously threatening gas safety and the reliability of the metering system.

[0007] Furthermore, it also includes a limiting pin, on the outer periphery of which an annular stop is fixedly installed.

[0008] Furthermore, one end of the hemispherical structure of both limiting pins faces the compression receiving groove; in the natural state of the two reset springs, one end of the hemispherical structure of both limiting pins is inserted into and in contact with the compression receiving groove, and at this time the other end of both limiting pins is received inside the reciprocating sliding insertion hole.

[0009] Furthermore, a locking slot with a circular groove structure is provided on the relatively inclined surfaces of the two limiting blocks; when the rear end face of the limiting block contacts the rear side of the inner end of the limiting slot, the reciprocating sliding insertion hole and the locking slot are coaxial; when the bottom end face of the transmission stud and the bottom end face of the mating protrusion are on the same horizontal plane, the extrusion column is slidably inserted into the extrusion receiving groove, and at this time the conical surface of the extrusion column contacts the hemispherical arc surface of the two limiting blocks; when the top end face of the transmission stud contacts the top surface of the inner end of the threaded transmission groove, the top end of the extrusion column contacts the top surface of the inner end of the extrusion receiving groove, and the outer peripheral surface of the extrusion column contacts the hemispherical arc surface of the two limiting blocks, at this time the other end of the two limiting blocks protrudes out of the reciprocating sliding insertion hole and is limited and inserted into the locking slot.

[0011] This utility model provides a smart gas meter with a quick installation and disassembly structure, which has the following advantages:

[0012] This utility model of intelligent gas meter achieves initial positioning by sliding the limiting plug into the limiting slot on the rear mounting plate, replacing the traditional bolt and nut fixing method. The installation process is simple and quick. After the limiting plug and the limiting slot are in place, the accompanying plug drives the transmission stud to move, and the extrusion pin compresses the limiting plug, causing it to expand and insert into the locking slot, achieving mechanical locking. This ensures that the intelligent gas meter and the support block are locked in place, effectively preventing loosening or falling off during use and ensuring the stability of the gas meter installation. When the locking is released, the accompanying plug is rotated in the opposite direction, and the limiting plug retracts, allowing the limiting plug to slide out of the limiting slot for quick disassembly. This significantly shortens the installation and disassembly time and improves work efficiency.

[0013] When the rear end face of the limiting plug contacts the inner rear side of the limiting slot, the reciprocating sliding insertion hole and the locking slot are coaxial, ensuring the accuracy of the locking operation and allowing the limiting plug to be accurately inserted into the locking slot. Furthermore, when the locking is released, the return spring releases its elastic force, pushing the annular stop block to retract the limiting plug, allowing the structure to automatically reset without additional manual operation. This simplifies the disassembly process and improves ease of use. The entire installation, locking, and disassembly process is clearly defined. Operators can precisely control the movement of the transmission stud and the extension / retraction of the limiting plug through the rotation of the accompanying plug, providing strong operational controllability. It also features anti-unprofessional disassembly protection. The mating slot at the bottom of the transmission stud has an elliptical groove structure. Without the accompanying plug, common tools cannot be inserted into the mating slot to rotate the transmission stud, thus preventing unprofessional personnel from arbitrarily disassembling the smart gas meter, ensuring the safety and accuracy of the gas meter's data, and preventing malfunctions or safety hazards caused by unprofessional disassembly.

[0029] The working principle of this embodiment:

[0030] Fasteners are inserted through the mounting holes 205 and fixedly connected to the mounting end face, thereby fixing the rear mounting plate 2 to the mounting end face. The smart gas meter 1 is initially positioned by sliding the limiting blocks 101 of the bottom symmetrical isosceles trapezoidal block structure into the limiting slots 204 of the isosceles trapezoidal groove structure on the rear mounting plate 2. Furthermore, the support block 201 on the rear mounting plate 2 enhances the structural strength through the reinforcing ribs 202, providing a supporting foundation for the smart gas meter 1.

[0031] When the rear end face of the limiting insert 101 contacts the inner rear side of the limiting slot 204, the reciprocating sliding insertion hole 206 and the locking slot 102 are coaxial. At this time, the operator inserts the portable insert 3 into the elliptical mating slot 401 at the bottom of the transmission stud 4. By rotating the portable insert 3 through the rectangular ring 301, the transmission stud 4 moves upward in the threaded transmission groove 207. The conical surface of the pressing column 402 at the top of the transmission stud 4 simultaneously presses the hemispherical arc surface of the two limiting inserts 5, thereby pushing the two limiting inserts 5 along the reciprocating sliding path. The insertion hole 206 expands to both sides, thereby causing the annular stop block 501 to slide in the reciprocating moving cavity 209, so that the other end of the limiting insertion post 5 extends out from the reciprocating sliding insertion hole 206 and is precisely inserted into the locking slot 102 of the limiting insertion block 101 to achieve mechanical locking. When the top of the transmission stud 4 contacts the top surface of the threaded transmission groove 207, the top of the extrusion post 402 presses against the top surface of the extrusion receiving groove 208. At this time, the limiting insertion post 5 is fully inserted into the locking slot 102 of the limiting insertion block 101, thereby achieving the locking and fixing of the positions of the smart gas meter 1 and the support block 201.

[0032] When the lock is released, the portable insert 3 is rotated in the opposite direction by the rectangular ring 301, the transmission stud 4 moves downward along the threaded transmission groove 207, the extrusion column 402 disengages from the extrusion of the limiting insert 5, at this time the return spring 502 releases its elastic force, pushes the annular stop 501 to drive the limiting insert 5 to retract into the reciprocating sliding insertion hole 206, and the hemispherical end is reinserted into the extrusion storage groove 208, thereby releasing the position lock and fixation of the smart gas meter 1 and the support block 201. At this time, the limiting insert 101 can be slid out from the limiting slot 204 to complete the quick disassembly of the smart gas meter 1;

[0033] Furthermore, the mating slot 401 has an elliptical groove structure. This special structure design makes it impossible to insert commonly used tools into the mating slot 401 to drive the drive stud 4 to rotate without the mating insert 3, thus avoiding the need for non-professionals to disassemble the smart gas meter 1.
