Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically relating to a connection structure between a Coriolis mass flow meter sensor and a transmitter. Background Technology

[0002] A Coriolis mass flow meter is a novel instrument that directly and precisely measures the mass flow rate of fluids. When fluid is introduced into the pipe while it vibrates synchronously, the pipe forces the fluid to vibrate up and down along with it. To resist this forced vibration, the fluid exerts a reaction force perpendicular to its flow direction. This force, known as the Coriolis effect, causes the pipe to vibrate asynchronously, resulting in a difference in the timing of vibration between the inlet and outlet sections (due to the opposite flow directions). This difference is called the phase time difference. This difference is directly proportional to the mass flow rate of the fluid flowing through the pipe. If this time difference can be detected by a circuit, the magnitude of the mass flow rate can be determined. This type of flow meter is called a Coriolis mass flow meter.

[0003] Coriolis mass flow meters are widely used in industrial fluid measurement. The reliability of the connection between the sensor and transmitter directly affects the measurement accuracy and equipment stability. Traditional connection methods, often using flange bolts, have the following drawbacks:

[0004] 1. Cumbersome installation: Multiple bolts need to be tightened one by one, which is time-consuming and labor-intensive, especially difficult to operate in a confined space;

[0005] 2. Poor vibration resistance: Long-term vibration can easily cause bolts to loosen, leading to signal transmission interruption or measurement deviation. Utility Model Content

[0006] The purpose of this invention is to provide a connection structure between a Coriolis mass flow meter sensor and a transmitter, aiming to solve the problems mentioned in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A connection structure between a Coriolis mass flow meter sensor and a transmitter includes:

[0009] A sensor body, one end of which is fixedly connected to a first connecting tube;

[0010] The second connecting pipe is detachably connected to one end of the first connecting pipe;

[0011] A transmitter, wherein the transmitter is fixedly connected to one end of the second connecting pipe;

[0012] A docking groove is formed at one end of the first connecting pipe;

[0013] A docking ring, which is fixedly connected to one end of the second connecting pipe;

[0014] Two sets of locking mechanisms are provided. Each set of locking mechanisms consists of an assembly block, a locking groove, a docking block, a plug-in groove, a plug-in rod, a rotating ring, a placement groove, and a spring. The locking groove is located at one end of the first connecting tube. The docking block is fixedly connected to the circumferential surface of the docking ring and is in contact with the locking groove. The rotating ring is rotatably connected to the outside of the first connecting tube. The assembly block is fixedly connected to the inner circumferential wall of the rotating ring. The placement groove is located inside the assembly block. The spring is fixedly connected to one side of the inner wall of the placement groove. The plug-in rod is fixedly connected to one end of the spring. The plug-in groove is located at one end of the docking block and the circumferential surface of the first connecting tube. The plug-in rod is movably inserted into the plug-in groove.

[0015] As a preferred embodiment of this utility model, a limiting groove is provided between the inner walls on both sides of the placement groove, and a limiting block is fixedly connected to the circumferential surface of the plug rod. The two limiting blocks are slidably connected in the two limiting grooves respectively.

[0016] In a preferred embodiment of this utility model, one end of the plug rod is fixedly connected to a pull rod, and a pull groove is provided on the circumferential surface of the rotating ring, with the pull rod slidably connected in the pull groove.

[0017] In a preferred embodiment of this utility model, one end of the pull rod is fixedly connected to a limiting plate, and the diameter of the limiting plate is larger than the diameter of the pull rod.

[0018] In a preferred embodiment of this utility model, a limiting groove is provided on the circumferential surface of the first connecting pipe, a limiting ring is slidably connected in the limiting groove, and a connecting rod is fixedly connected between the circumferential surface of the limiting ring and the circumferential surface of the rotating ring.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. In this solution, the rotating ring drives the locking mechanism to achieve "one-click" locking / unlocking of the sensor and transmitter, which greatly improves the operating efficiency. The spring continuously presses the plug rod into the plug slot to form a self-locking force. The limit block and the limit slot cooperate to prevent the plug rod from shifting and ensure a stable connection under vibration.

[0023] 2. In this design, the pull rod is hidden inside the pull groove to prevent accidental detachment due to external force collision. The limiting plate prevents the pull rod from completely detaching to prevent parts loss. The nested design of the docking ring and docking groove, docking block and card slot ensures the axial / circumferential positioning accuracy of the transmitter and sensor body. The connecting rod links the rotating ring and the limiting ring to enhance the stability of rotation operation. Attached Figure Description

[0032] Please see Figure 1-3 The present invention provides the following technical solution:

[0033] A connection structure between a Coriolis mass flow meter sensor and a transmitter includes:

[0034] Sensor body 1, with a first connecting tube 2 fixedly connected to one end of sensor body 1;

[0035] The second connecting pipe 3 is detachably connected to one end of the first connecting pipe 2;

[0036] Transmitter 4 is fixedly connected to one end of the second connecting pipe 3;

[0037] A docking groove is provided at one end of the first connecting pipe 2;

[0038] The docking ring 13 is fixedly connected to one end of the second connecting pipe 3;

[0039] Two sets of snap-fit ​​mechanisms are provided. Each set of snap-fit ​​mechanisms consists of an assembly block 23, a snap-fit ​​groove 11, a docking block 12, a plug-in groove 20, a plug-in rod 19, a rotating ring 10, a placement groove 17, and a spring 18. The snap-fit ​​groove 11 is located at one end of the first connecting tube 2. The docking block 12 is fixedly connected to the circumferential surface of the docking ring 13 and is opposite to the snap-fit ​​groove 11. The rotating ring 10 is rotatably connected to the outside of the first connecting tube 2. The assembly block 23 is fixedly connected to the inner circumferential wall of the rotating ring 10.

The plug-in rod 19 is fixedly connected to one end of the spring 18. The plug-in groove 20 is located at one end of the docking block 12 and the circumferential surface of the first connecting tube 2. The plug-in rod 19 is movably inserted into the plug-in groove 20.

[0040] In a specific embodiment of this utility model,

[0041] The sensor body 1 has a first connecting pipe 2 welded to its left end, with an annular mating groove on its end face. The transmitter 4 has a second connecting pipe 3 fixed to its right end, and a mating ring 13 fixed to the left end of the second connecting pipe 3. During installation: insert the mating ring 13 into the mating groove of the first connecting pipe 2, align the mating block 12 with the card and slot 11 and push it in. Rotate the rotating ring 10 clockwise, which will drive the assembly block 23 to rotate synchronously, pressing the plug rod 19 to compress the spring 18. When the plug rod 19 is aligned with the plug slot 20 on the mating block 12, the spring 18 releases its elastic force, pushing the plug rod 19 into the plug slot 20, thus completing the mechanical locking.

[0042] Please refer to the details. Figure 2Limiting grooves 21 are provided between the inner walls of both sides of the placement groove 17. Limiting blocks 22 are fixedly connected to the circumferential surface of the plug rod 19. The two limiting blocks 22 are slidably connected in the two limiting grooves 21 respectively. A pull rod 16 is fixedly connected to one end of the plug rod 19. A pull groove 15 is provided on the circumferential surface of the rotating ring 10. The pull rod 16 is slidably connected in the pull groove 15. A limiting plate 14 is fixedly connected to one end of the pull rod 16. The diameter of the limiting plate 14 is larger than the diameter of the pull rod 16.

[0043] In this embodiment: the limiting blocks 22 on both sides of the plug rod 19 are embedded in the limiting grooves 21 of the assembly block 23. When the equipment vibrates, the limiting blocks 22 slide along the limiting grooves 21 to prevent the plug rod 19 from shaking radially and ensure that the insertion depth is constant. When disassembling: the limiting plate 14 is pulled outward, which drives the pull rod 16 to slide along the pull groove 15, forcing the plug rod 19 to exit the plug groove 20. The diameter of the limiting plate 14 is larger than the opening of the pull groove 15 to prevent the pull rod 16 from completely coming out.

A limiting ring 8 is slidably connected in the limiting groove 7. A connecting rod 9 is fixedly connected between the circumferential surface of the limiting ring 8 and the circumferential surface of the rotating ring 10.

[0045] In this embodiment, the rotating ring 10 is fixed to the limiting ring 8 via the connecting rod 9. The limiting ring 8 slides within the annular groove 7 of the first connecting pipe 2, allowing the rotating ring 10 to rotate only circumferentially and preventing axial movement.

[0046] Please refer to the details. Figure 3 One end of the transmission tube 5 is fixedly connected to the mounting plate 6, and one end of the mounting plate 6 has multiple connection holes. One end of the limiting plate 14 is fixedly connected to the handle, and the circumferential surface of the handle has multiple anti-slip textures.

[0047] In this embodiment: the transmitter 4 is connected to the transmission pipe 5 at the left end, and the transmission pipe 5 is welded to the end of the mounting plate 6 with connection holes to facilitate bolt fixing to external equipment. A grip with anti-slip texture is added to the outside of the limiting plate 14 to improve the manual operation feel.

[0048] Working principle and usage process of this utility model:

[0049] The sensor body 1 has a first connecting pipe 2 welded to its left end, with an annular mating groove on its end face. The transmitter 4 has a second connecting pipe 3 fixed to its right end, and a mating ring 13 fixed to the left end of the second connecting pipe 3. During installation: insert the mating ring 13 into the mating groove of the first connecting pipe 2, align the mating block 12 with the card and slot 11 and push it in. Rotate the rotating ring 10 clockwise, which will drive the assembly block 23 to rotate synchronously, pressing the plug rod 19 to compress the spring 18. When the plug rod 19 is aligned with the plug slot 20 on the mating block 12, the spring 18 releases its elastic force, pushing the plug rod 19 into the plug slot 20, thus completing the mechanical locking.
