Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flowmeter technology, and specifically to a flowmeter with quick wiring function. Background Technology

[0002] Electromagnetic flow meters are flow measurement instruments designed based on Faraday's law of electromagnetic induction. They generate a magnetic field through a sensor, and when a conductive liquid flows through it, an induced electromotive force proportional to the flow rate is generated. The converter processes the signal and displays it as flow data. They have advantages such as no moving parts, corrosion resistance, and stable measurement, and are widely used in the measurement of the volumetric flow rate of conductive liquids in industries such as water treatment, chemical industry, and metallurgy.

[0003] Existing electromagnetic flowmeters typically consist of two main parts: a sensor and a meter head. Multiple cables are required to connect the sensor and meter head. To facilitate disassembly and maintenance of the sensor and meter head, the connecting cables are usually quite long and housed inside conduits. However, when assembling the sensor and meter head, the connecting cables are prone to bending as the distance between them decreases, causing interference with the connection between the mounting plates. Furthermore, the lack of insulation between the cables makes them prone to tangling, complicating maintenance. Therefore, a flowmeter with quick-connection functionality is proposed to address these issues. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A flow meter with quick-connect function includes a sensor, and a meter head is provided on the outside of the sensor;

[0006] The sensor includes a measuring tube, with a connecting tube first fixedly connected to the side of the measuring tube. A mounting plate first is fixedly installed at the end of the connecting tube first. A storage sleeve is inserted into the inner wall of the middle of the connecting tube first and the mounting plate first. The storage sleeve extends along the length of the connecting tube first, and the outer diameter of the storage sleeve is the same as the inner diameter of the connecting tube first. Several mounting grooves are formed on the inner surface of the storage sleeve. Each mounting groove is equidistantly arranged around the central axis of the storage sleeve. An installation strip is inserted into and slidably connected to the inner side of each mounting groove. Anti-slip strips are glued and fixed to both sides of the outer wall of each installation strip. One end of the installation strip extends to the outside of the mounting groove and is fixedly connected to a limiting frame. The limiting frame extends along the length of the storage sleeve.

[0007] As a further embodiment of this utility model: a limiting hole is provided at one end of the surface of the storage sleeve, and a positioning hole is provided through one side of the end face of the storage sleeve. The positioning hole extends in the length direction of the storage sleeve, and the end of one side of each mounting groove extends to the same end face of the storage sleeve.

[0008] As a further embodiment of this utility model: a guide groove is provided on the top surface of the outer wall of the storage sleeve, the guide groove extends along the length direction of the storage sleeve as a whole, a guide block is slidably connected to the inner wall of the guide groove, and the top end of the guide block is fixedly connected to the inner side wall of the mounting plate.

[0009] As a further embodiment of this utility model: the meter head includes a second wiring tube, the end of which is fixedly connected to a second mounting plate. A support groove is provided in the middle of the inner sidewall of the second mounting plate. One end of the support groove extends to the end face of the second mounting plate. A positioning rod is fixedly connected to one end of the inner wall of the support groove. The positioning rod extends along the length of the second wiring tube. A limit bolt is inserted into and threadedly fastened to one end of the outer wall of the second wiring tube. The end of the limit bolt extends into the interior of the second wiring tube.

[0010] As a further embodiment of this utility model: the end face of the second mounting plate abuts against the end face of the first mounting plate, and a plurality of fastening bolts are connected through the surface of the second mounting plate.

[0012] As a further embodiment of this utility model: the positioning rod is inserted into and slidably connected to the inside of the positioning hole, and the limiting bolt is aligned with and inserted into the end of the limiting hole.

[0013] The beneficial effects of this utility model are:

[0014] (1) The present invention provides a storage sleeve inside the wiring tube one on the sensor side. After the cable between the sensor and the meter head is connected, the storage sleeve is slid out. During this period, the storage sleeve gathers the cable to its own inside. The end of the storage sleeve is inserted into the wiring tube two on the meter head side and fixed. After the wiring tube one and the wiring tube two are closed, the cable inside will not bend outward and cause interference when closing, which helps to quickly connect the sensor and the meter head.

[0015] (2) An additional limiting frame can be connected inside the storage sleeve. The connecting cable between the sensor and the meter can pass through the limiting frame. The limiting frame can guide and isolate each cable, thereby preventing different cables from getting tangled together due to bending. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5As shown, a flow meter with quick-connection function includes a sensor 1, with a meter head 2 disposed on the outer side of the sensor 1; the sensor 1 includes a measuring tube 101, with a connecting tube 102 passing through and fixedly connected to the side of the measuring tube 101, and a mounting plate 103 fixedly installed at the end of the connecting tube 102; a receiving sleeve 105 is inserted into the middle inner wall of the connecting tube 102 and the mounting plate 103, and the receiving sleeve 105 extends along the length of the connecting tube 102, with the outer diameter of the receiving sleeve 105 being the same as that of the connecting tube 102. The inner diameter of tube 102 is uniform. Several mounting grooves 108 are formed on the inner surface of the storage sleeve 105. Each mounting groove 108 is equidistant from the central axis of the storage sleeve 105. An mounting strip 110 is inserted into and slidably connected to the inner side of each mounting groove 108. Anti-slip strips 111 are adhered and fixed to both sides of the outer wall of each mounting strip 110. One end of the mounting strip 110 extends to the outside of the mounting groove 108 and is fixedly connected to a limiting frame 112. The limiting frame 112 extends along the length of the storage sleeve 105. Figure 4 As shown, the anti-slip strip 111 can be made of rubber, thereby increasing the friction between the mounting strip 110 and the mounting groove 108, and preventing the mounting strip 110 from coming out of the mounting groove 108.

[0025] A limiting hole 109 is formed at one end of the surface of the storage sleeve 105, and a positioning hole 106 is formed through one end face of the storage sleeve 105. The positioning hole 106 extends along the length of the storage sleeve 105, and one end of each mounting groove 108 extends to the same end face of the storage sleeve 105. Figure 4 As shown, the mounting strip 110 can be removed from the right end of the mounting groove 108, which facilitates the disassembly of the limit frame 112.

[0026] A guide groove 107 is formed on the top surface of the outer wall of the storage sleeve 105. The guide groove 107 extends along the length of the storage sleeve 105. A guide block 104 is slidably connected to the inner wall of the guide groove 107. The top end of the guide block 104 is fixedly connected to the inner side wall of the mounting plate 103. Figure 3 As shown, the guide block 104 slides along the guide groove 107, thereby preventing the storage sleeve 105 from completely coming out of the wiring tube 102.

[0027] Meter head 2 includes a second wiring conduit 201, with a mounting plate 202 fixedly connected to its end. A support groove 205 is formed in the middle of the inner wall of the mounting plate 202, with one end extending to the end face of the mounting plate 202. A positioning rod 206 is fixedly connected to one end of the inner wall of the support groove 205, extending along the length of the wiring conduit 201. A limit bolt 207 is inserted into and threadedly fastened to one end of the outer wall of the wiring conduit 201, with the end of the limit bolt 207 extending into the interior of the wiring conduit 201. Figures 3-5 As shown, the storage sleeve 105 can be accommodated in the support groove 205.

[0028] The end face of mounting plate two 202 abuts against the end face of mounting plate one 103. Several fastening bolts 203 are threaded through the surface of mounting plate two 202, each bolt 203 penetrating the mounting plate one 103. A nut 204 is threaded onto the end of each bolt 203, and the surface of the nut 204 abuts against the surface of mounting plate one 103. Figures 1-2 As shown, mounting plate 202 and mounting plate 103 are provided with flange holes on their surfaces to facilitate fixing with bolts.

[0029] The storage sleeve 105 is inserted into the wiring conduit 201 and the mounting plate 202. The end face of the storage sleeve 105 abuts against the inner side of the support groove 205. Figures 4-5 As shown, the support groove 205 can also support the end of the mounting strip 110, thereby fixing the mounting strip 110 inside the mounting groove 108.

[0030] The positioning rod 206 is inserted into and slidably connected to the positioning hole 106, and the limiting bolt 207 is aligned with and inserted into the end of the limiting hole 109. Figure 5 As shown, a sealing washer is provided between the limit bolt 207 and the second wiring pipe 201 to seal the connection gap between the limit bolt 207 and the second wiring pipe 201.

[0031] The working principle of this utility model:

[0032] When the device is in use, the connecting cable between the sensor 1 and the meter 2 can be passed through the limiting frame 112 respectively, and the anti-slip strip 111 can be inserted into the mounting groove 108. The relative fixation between the limiting frame 112 and the mounting groove 108 can be achieved through the friction between the anti-slip strip 111 and the mounting groove 108.

[0033] Secondly, after the connecting cable between sensor 1 and meter head 2 is connected, the storage sleeve 105 can be pushed out from inside the first wiring tube 102, and the end of the storage sleeve 105 can be inserted into the second wiring tube 201. During this process, the positioning rod 206 is inserted into the inside of the positioning hole 106 to ensure that the limit hole 109 is aligned with the end of the limit bolt 207. Then, the limit bolt 207 is tightened and inserted into the limit hole 109, and the storage sleeve 105 is fixed relative to the second wiring tube 201. Then, the meter head 2 is pushed horizontally. As the sensor approaches, the guide block 104 slides along the guide groove 107 until the second mounting plate 202 abuts against the first mounting plate 103. During this process, due to the isolation provided by the storage sleeve 105, the cable will not bend outwards from the first wiring tube 102, thus preventing interference with the connection between the second mounting plate 202 and the first mounting plate 103. Finally, the fastening bolt 203 is passed through the second mounting plate 202 and the first mounting plate 103, and the nut 204 is tightened at the end of the fastening bolt 203, thus fixing the sensor 1 and the meter head 2 together.
