[0002] A transmitter is an electrical instrument, and its function is to convert some measured or controlled physical quantities into standard electrical signals for operations such as measurement, remote transmission, and control. In a Coriolis flowmeter, the transmitter is installed on the flowmeter housing through a connection structure, and the transmitter is connected to a pressure sensor inside the flowmeter housing through a wire.

[0003] In some installation environments, due to space limitations or layout requirements, it is necessary to rotate the transmitter by a certain angle to adapt to the installation space. The traditional connection structure is that two separable connection seats are connected by a clamp. When it is necessary to rotate and adjust the transmitter, it is necessary to turn the bolts on the clamp to loosen the bolts, then rotate and adjust the connection seat provided with the transmitter, and then tighten the screw rod to make the clamp clamp the two connection seats. The operation of repeatedly turning the screw rod is rather troublesome. Summary of the Utility Model

[0023] The following is combined with Figures 1-3 to make a detailed description of the present invention.

[0024] Embodiment

[0025] A connection structure of a transmitter, comprising an installation cylinder 3 fixedly installed on a flowmeter housing 1, a cover body 4 is covered on the installation cylinder 3, a transmitter 2 is installed on the cover body 4, a locking mechanism 5 is arranged on the side wall of the cover body 4, the locking mechanism 5 includes a plug rod 503 that movably penetrates the cover body 4 along the radial direction of the cover body 4, and a plurality of slots 11 that cooperate with the plug rod 503 are arranged on the outer wall of the installation cylinder 3 along the circumferential direction.

[0026] The cover body 4 is detachably connected to the installation cylinder 3 by inserting the plug rod 503 into the slot 11; when the plug rod 503 is inserted into the slot 11, it can prevent the cover body 4 from axially disengaging from the installation cylinder 3 and the relative rotation between the cover body 4 and the installation cylinder 3.

[0027] The locking mechanism 5 further includes a housing 501 fixedly arranged on the outer wall of the cover body 4, a spring 502 sleeved on the plug rod 503 is arranged in the housing 501, and a pressing plate 504 for compressing the spring 502 is fixedly arranged on the plug rod 503. The spring 502 is provided to keep the plug rod 503 inserted into the slot 11 to prevent the plug rod 503 from disengaging from the slot 11 and causing the cover body 4 to lose its restraint and rotate. The plug rod 503 can also be a screw rod, that is, the plug rod 503 threadedly penetrates the cover body 4, but it takes more time to rotate the screw rod, so the method of driving the plug rod 503 to move by the spring 502 is preferably used.

[0028] An arc-shaped head is arranged at one end of the plug rod 503 close to the slot 11. The arrangement of the arc-shaped head facilitates the quick insertion of the plug rod 503 into the slot 11.

[0029] A sealing ring 6 is sleeved on the outer wall of the mounting cylinder 3. The sealing ring 6 seals the gap between the cover body 4 and the mounting cylinder 3.

[0030] An arc-shaped top head is annularly arranged at the top of the mounting cylinder 3. The setting of the arc-shaped top head can reduce the friction between the top of the mounting cylinder 3 and the cover body 4 and facilitate the rotation of the cover body 4.

[0031] A socket 12 electrically connected to the transmitter 2 is arranged on the inner side of the cover body 4. The socket 12 is detachably connected with a plug 7, and the plug 7 is connected with a wire 8. After the plug 7 is connected to the socket 12, the transmitter 2 is electrically connected to the pressure sensor through the wire 8.

[0032] A stepped hole 10 is arranged at the lower end of the mounting cylinder 3. A baffle 9 for blocking the stepped hole 10 is placed in the stepped hole 10, and the wire 8 is fixedly penetrated through the baffle 9. After the baffle 9 blocks the stepped hole 10, it is convenient to fill glue in the stepped hole 10. After the glue solidifies, the stepped hole 10 can be sealed, realizing the isolation between the flowmeter housing 1 and the external environment.

[0033] After the cover body 4 covers the mounting cylinder 3, it can prevent impurities or water from entering the gap between the cover body 4 and the mounting cylinder 3 from top to bottom and entering the inner side of the mounting cylinder 3 to affect the normal operation of the plug 7 and the socket 12. The sealing ring 6 can prevent water vapor from entering the inner side of the mounting cylinder 3 to affect the normal operation of the plug 7 and the socket 12.

[0034] As Figure 3 shown, the slot 11 is only distributed within a certain angle to limit the rotation angle of the cover body 4 and avoid damage to the wire 8 due to excessive rotation angle. Among them, the wire 8 is relatively long, allowing the wire 8 to rotate a certain angle.

[0035] Installation process of the connection structure:

[0036] First, fixedly weld the mounting cylinder 3 to the flowmeter housing 1, then lead out the wire 8 connected to the pressure sensor from the stepped hole 10 and sleeved with the baffle 9, and then fill glue into the stepped hole 10; after the glue solidifies, connect the wire 8 to the plug 7 and then connect the plug 7 to the socket 12.

[0037] After rotating the cover body 4 to a suitable position, insert the insertion rod 503 into the slot 11 to complete the fixation of the cover body 4.

[0038] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
