[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0038] Reference Figure 1-Figure 3 The utility model provides an embodiment: a cone tube flowmeter, including a cone tube flowmeter seat 1, a differential pressure transmitter 2 is fixedly connected to the top of the cone tube flowmeter seat 1, a positioning groove 3 is provided inside the differential pressure transmitter 2, a card slot 4 is provided inside the differential pressure transmitter 2, a cover plate 5 is slidably connected inside the differential pressure transmitter 2, a positioning block 6 is fixedly connected to the outer wall of the cover plate 5, the outer wall of the positioning block 6 is slidably connected to the inside of the positioning groove 3, a knob 7 is rotatably connected inside the cover plate 5, one end of the knob 7 is fixedly connected to a connecting disk 8, a connecting rod 9 is rotatably connected inside the connecting disk 8, and a limited position is provided inside the cover plate 5 Slot 10, one end of the connecting rod 1 9 is rotatably connected to the connecting rod 2 11, the outer wall of the connecting rod 2 11 is slidably connected to the inside of the cover plate 5, the outer wall of the connecting rod 2 11 is provided with a reset assembly, one end of the connecting rod 2 11 is fixedly connected to the limiting plate 12, the outer wall of the limiting plate 12 is slidably connected to the inside of the limiting groove 10, one side of the limiting plate 12 is fixedly connected to a clamping block 13, the outer wall of the clamping block 13 is embedded in the inside of the clamping slot 4, the reset assembly includes a spring 14, the spring 14 is internally sleeved on the outer wall of the connecting rod 2 11, one end of the spring 14 is fixedly connected to the other side of the limiting plate 12, and the other side of the spring 14 is fixedly connected to the inside of the cover plate 5;
[0039] Specifically, when repairing the differential pressure transmitter 2, this mechanism drives the entire disassembly process by rotating the knob 7. When the knob 7 is rotated, it drives the connecting disk 8 to rotate synchronously. The rotation of the connecting disk 8 further drives the connecting rod 1 9 to move, and the connecting rod 1 9 pulls the connecting rod 2 11 to retract into the interior of the cover plate 5. The retraction action of the connecting rod 2 11 further drives the block 13 to retract into the interior of the limiting groove 10. The block 13 is limited inside the limiting groove 10 by the limiting plate 12 to ensure its stability and accuracy during movement. When the block 13 is completely retracted into the limiting groove 10, the connection between it and the slot 4 will be released, and the cover plate 5 can be quickly disassembled at this time, thereby exposing the differential pressure transmitter 2 inside.
[0040] Reference Figure 1 and Figure 4 The outer wall of the differential pressure transmitter 2 is fixedly connected with a connecting seat 15, and the connecting seat 15 is symmetrically arranged and fixedly connected to the outer wall of the differential pressure transmitter 2. A connecting groove 16 is opened inside the connecting seat 15, and a fixing groove 18 is opened inside the connecting seat 15. A contact piece 17 is fixedly connected inside the connecting seat 15, and the contact piece 17 is arranged in an annular array and fixedly connected inside the connecting seat 15. A card 19 is fixedly connected inside the connecting seat 15, and the card 19 is arranged in an annular array and fixedly connected inside the connecting seat 15. A release sleeve 20 is slidably connected inside the connecting seat 15, and one end of the release sleeve 20 is fixedly connected to a limiting ring 21, and the outer wall of the limiting ring 21 is slidably connected inside the fixing groove 18;
[0041] Specifically, the installation process of the cable is extremely simple. You only need to insert the cable directly into the inside of the connection seat 15. When the cable is inserted into the connection seat 15, the copper core inside the cable will naturally enter the connection groove 16 and achieve contact connection with the contact piece 17. This structural design ensures close contact between the copper core and the contact piece 17, thereby ensuring stable signal transmission. At the same time, the access to the differential pressure transmitter 2 also makes this connection system more functional and flexible. In addition to ensuring the stability of the internal connection, the connection seat 15 also fully considers the fixing problem of the cable. Inside the fixing groove 18, the outer wall of the cable is tightly fixed by the engagement of the card 19, thereby effectively preventing the accidental unplugging of the cable. This design not only enhances the stability of the cable connection, but also reduces the risk caused by loose or unplugged cables. Of course, convenient disassembly is equally important. When the cable needs to be disassembled, just push the release sleeve 20 into the inside of the connection seat 15, and drive the limit ring 21 through the release sleeve 20 to separate the card 19 from the cable sheath. In this process, the user does not need to use any tools, and can complete the disassembly with hand strength alone. Then, just gently pull out the cable. The entire disassembly process is also simple and quick.
[0042] Working principle: When the cone flow meter is used, if the differential pressure transmitter 2 needs to be repaired, the knob 7 is rotated to drive the connecting plate 8 to rotate. When the connecting plate 8 rotates, the connecting rod 1 9 is driven to pull the connecting rod 2 11 into the cover 5. The connecting rod 2 11 drives the block 13 to retract into the limit groove 10. The block 13 is limited in the limit groove 10 by the limit plate 12. When the block 13 is separated from the card slot 4, the cover 5 can be quickly disassembled to repair the differential pressure transmitter 2, achieving the effect of quickly disassembling the cover 5. When installing the cable, you only need to directly insert the cable into the connecting seat 15, insert the copper core inside the cable into the connecting groove 16, make the copper core contact with the contact piece 17 to connect the differential pressure transmitter 2, and the outer wall of the cable is embedded in the fixing groove 18 through the card 19 to prevent the cable from being pulled out. When the cable needs to be removed, you only need to push the release sleeve 20 into the connecting seat 15, and use the release sleeve 20 to drive the limit ring 21 to separate the card 19 from the cable sheath, and then pull out the cable, thereby achieving the effect of quickly installing the cable.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
