Description

Technical Field

[0001] The utility model relates to the technical field of control instruments, in particular to a digital display control instrument. Background Art

[0002] A control instrument refers to an instrument that automatically controls the controlled variable. It compares the measured signal with the given value, calculates the deviation signal according to a certain control rule, and outputs the operation result as a specified signal. Common controlled variables include temperature, flow, pressure, liquid level and composition.

[0003] In the prior art, the detection sensor used to provide the measurement signal to the control instrument is fixedly installed and cannot be extended or retracted. If it is fixedly installed in the liquid to be detected, it is easy to be corroded and rusted. If it is fixedly installed in the object to be detected, it is easy to be bumped or hit by the object. Therefore, a digital display control instrument is proposed, which has a telescopic structure. When detection is required, it is pushed downward, and after the detection is completed, it is driven to move upward, so that the detection sensor is not easily corroded or damaged. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a digital display control instrument with a telescopic structure, which is pushed downward when detection is required and driven upward after the detection is completed, so that the detection sensor is not easily corroded or damaged.

[0006] A detection sensor is installed on one side of the tube body through a mounting frame, a wiping assembly is provided on one side of the sleeve, and the wiping assembly includes a connecting rod fixed to one side of the sleeve through a flange, a ring is welded at one end of the connecting rod, and a soft rubber pad is glued to the inside of the ring.

[0007] By adopting the above technical solution, a small motor drives the screw rod to rotate through the threaded groove to push the tube body and the detection sensor up and down. When the detection sensor moves up, the soft rubber pad on the inner side of the ring can wipe its surface.

[0008] Specifically, the outer side of the tube body located inside the sleeve is fixed with a limiting ring by bolts, a thread groove is opened inside the tube body, and the bottom end of the screw rod is located inside the thread groove.

[0009] Specifically, limiting slide bars are welded on both sides of the inner part of the sleeve, limiting slide grooves are arranged on both sides of the limiting ring, and the limiting slide bars are located inside the limiting slide grooves.

[0010] Specifically, the current output terminal of the digital display control instrument is electrically connected to the current input terminal of the detection sensor through a power line.

[0011] Specifically, a flange ring is welded to the top end of the outer side of the sleeve, and the flange ring is fixed to the bottom of the mounting plate by bolts.

[0023] It has a telescopic structure, which can be pushed down when testing is needed, and moved up after the test is completed, making the test sensor less prone to corrosion and damage. Figure 1-4 As shown, a digital display control instrument described in the utility model includes a mounting plate 1 and a limit ring 306, a digital display control instrument 2 is installed on the top of the mounting plate 1 through a mounting seat, a telescopic component 3 is arranged at the bottom of the mounting plate 1, and the telescopic component 3 includes a sleeve 301 located at the bottom of the mounting plate 1, a small motor 303 is installed on the top of the sleeve 301 through a mounting frame, and the output shaft at the bottom of the small motor 303 is connected to a screw rod 304 through a connecting sleeve, and a tube body 302 is sleeved on the bottom end of the sleeve 301;

[0024] A detection sensor 4 is installed on one side of the tube body 302 through a mounting frame, and a wiping assembly 5 is provided on one side of the sleeve 301. The wiping assembly 5 includes a connecting rod 501 fixed to one side of the sleeve 301 through a flange, and a ring 502 is welded at one end of the connecting rod 501. A soft rubber pad 503 is glued to the inner side of the ring 502.

[0025] When in use, the small motor 303 drives the screw rod 304 to rotate through the thread groove 305 to push the tube body 302 and the detection sensor 4 to move up and down. When the detection sensor 4 moves up, the soft rubber pad 503 on the inner side of the ring 502 can wipe its surface.

[0026] For example, Figure 3 As shown, the utility model also includes that the outer side of the tube body 302 located inside the sleeve 301 is fixed with a limit ring 306 by bolts, a thread groove 305 is opened inside the tube body 302, and the bottom end of the screw rod 304 is located inside the thread groove 305.

[0027] When in use, the screw rod 304 rotates through the thread groove 305 to push the tube body 302 to move up and down, and the limiting ring 306 can prevent the tube body 302 from falling off from the sleeve 301.

[0028] For example, Figure 3 As shown, the utility model also includes that limiting slide bars 307 are welded on both sides of the inner part of the sleeve 301 , limiting slide grooves 308 are provided on both sides of the limiting ring 306 , and the limiting slide bars 307 are located inside the limiting slide grooves 308 .

[0029] When in use, the setting of the limiting slide bar 307 and the limiting slide groove 308 can prevent the tube body 302 from rotating along with the screw rod 304 .

[0030] For example, Figure 1 As shown, the utility model also includes that the current output end of the digital display control instrument 2 is electrically connected to the current input end of the detection sensor 4 through a power line.

[0037] When detection is required, the small motor 303 is turned on to drive the screw rod 304 to rotate, and the tube body 302 is pushed downward through the thread groove 305. When the tube body 302 moves downward, the detection sensor 4 is inserted into the detected medium, and the detection sensor 4 detects it and transmits the detection data to the digital display control instrument 2. The digital display control instrument 2 outputs the signal after processing. After the detection is completed, the small motor 303 drives the screw rod 304 to reverse, so that the tube body 302 and the detection sensor 4 move upward and reset;

[0038] The tube body 302 moves up and down, and the limiting ring 306 slides on the outside of the limiting slide bar 307 through the limiting slide groove 308, which can prevent the tube body 302 from rotating with the screw rod 304 without affecting the up and down movement of the tube body 302. The limiting ring 306 can prevent the tube body 302 from falling off from the sleeve 301;

[0039] When the detection sensor 4 is completed and moved upward, it is inserted into the ring 502 , and the soft rubber pad 503 inside the ring 502 can wipe its surface, so as to facilitate the detection of the medium adhering to the surface of the sensor 4 .
