Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a pressure switch sensor detection device. Background Art

[0002] The detection device is a device used to detect the pressure switch sensor. When using the detection device, use the voltage range of the multimeter to measure the zero-point output of the sensor without pressure applied. This output is usually a voltage in the mV level to determine whether the zero-point deviation exceeds the technical indicator range. If the voltage exceeds the technical indicator of the sensor, it indicates that the zero-point deviation of the sensor has exceeded the range. After powering the sensor, change the state of the sensor's air guide holes by blowing or applying air pressure, and use the voltage range of the multimeter to observe the voltage changes at the output end of the sensor. By changing the state of the sensor's air guide holes, measure the voltage changes and evaluate the sensitivity. If the sensor has a high relative sensitivity, this change will be more obvious. If there is no change, you may need to use a more accurate air pressure source to apply pressure, which can well detect the pressure switch sensor.

[0003] In daily work, the inventor found that the detection device still has at least the following problems: when using the detection device, the voltage range of the multimeter is used to measure the zero-point output of the sensor without applying pressure. This output is usually a voltage in the mV level to determine whether the zero-point deviation exceeds the technical indicator range. If the voltage exceeds the technical indicator of the sensor, it indicates that the zero-point deviation of the sensor has exceeded the range. After powering the sensor, the state of the air guide hole of the sensor is changed by blowing air or applying air pressure, and the voltage range of the multimeter is used to observe the voltage change at the output end of the sensor. The voltage change is measured by changing the state of the air guide hole of the sensor to evaluate the sensitivity. If the sensor has a high relative sensitivity, this change will be more obvious. If there is no change, it may be necessary to use a more accurate air pressure source to apply pressure. This can well detect the pressure switch sensor, but in actual use, because the connection line of the multimeter is relatively long, it is more troublesome to store the multimeter.

The block 2616 is slidably connected to the inner wall of the limit bar 2615. Under the restriction of the limit rod 2612, the connecting frame 2610 is manually controlled to rotate on the surface of the storage tray 2602, and then the connecting frame 2610 is controlled to move to a suitable position, and then the limit bar 2615 is pulled toward the inner wall of the storage tray 2602 through the first spring 2620, so that the limit bar 2615 can be squeezed on the surface of the connecting line 25, so that the connecting line 25 can be restricted to the inner wall of the storage tray 2602. When the limit bar 2615 is not in use, the limit bar 2615 is controlled to slide on the inner wall of the sliding frame 2614, and then the limit bar 2615 is slid into the inside of the first rectangular groove 2617. At this time, the rubber frame 2618 is squeezed on the surface of the limit bar 2615.In this way, the limit bar 2615 can be restricted inside the first rectangular groove 2617, thereby preventing the limit bar 2615 from affecting the connection line 25 from being wrapped around the inner wall of the storage tray 2602.

When the storage tray 2602 is rotated to a suitable position, the third spring 2624 pulls the slider 2622 toward the storage tray 2602, thereby causing the rubber block 2625 to be pressed against the side of the storage tray 2602 near the rotating rod 2601. This allows the rubber block 2625 to be pressed against the protrusion 2626, thus confining the storage tray 2602 to one side of the multimeter body 22.

In this way, the baffle 2708 can be set on the top of one side of the L-shaped plate 2705. 2706, and the baffle 2708 is pressed in the direction away from the storage groove 2707 by the fourth spring 2710. 6, a second rectangular groove 2714 is formed on one side of the L-shaped plate 2705.

[0033] Working principle: When using the detection device, use the voltage range of the multimeter to measure the zero-point output of the sensor without applying pressure. This output is usually a voltage in the mV level to determine whether the zero-point deviation exceeds the technical indicator range. If the voltage exceeds the technical indicator of the sensor, it means that the zero-point deviation of the sensor has exceeded the range. After powering the sensor, change the state of the sensor's air guide holes by blowing or applying air pressure, and use the voltage range of the multimeter to observe the voltage changes at the output end of the sensor. By changing the state of the sensor's air guide holes, measure the voltage changes and evaluate the sensitivity. If the sensor has a high relative sensitivity, this change will be more obvious. If there is no change, you may need to use a more accurate air pressure source to apply pressure, which can be a good way to sense the pressure switch. When the storage device 26 is used, the end of the connecting wire 25 away from the multimeter body 22 is inserted into the inside of the circular groove 2603, and then the surface of the end of the connecting wire 25 away from the multimeter body 22 is squeezed by the inner wall of the first rubber plate 2604, so that the end of the connecting wire 25 away from the multimeter body 22 is restricted to the inner wall of the storage tray 2602, and then the connecting wire 25 is controlled to be wound around the inside of the storage tray 2602. Under the restriction of the limiting rod 2612, the connecting frame 2610 is manually controlled to rotate on the surface of the storage tray 2602, and then the connecting frame 2610 is controlled to move to a suitable position, and then the limiting bar 2615 is pulled toward the inner wall of the storage tray 2602 by the first spring 2620, so that the limiting bar 2615 can be pulled. 615 is squeezed on the surface of the connecting line 25, so that the connecting line 25 can be restricted to the inner wall of the storage tray 2602. When the limit bar 2615 is close to the inner wall of the storage tray 2602, the second spring 2607 squeezes the sliding ring 2608 in the direction close to the limit bar 2615, so that the rubber ring 2609 can be squeezed on one end of the limit bar 2615, so that the limit bar 2615 can be restricted to the inner wall of the storage tray 2602. When the storage tray 2602 is rotated to a suitable position, the sliding block 2622 is pulled in the direction close to the storage tray 2602 by the third spring 2624, thereby squeezing the rubber block 2625 on the side of the storage tray 2602 close to the rotating rod 2601, so that the rubber block 2625 can be squeezed on The protrusion 2626 is positioned on the storage tray 2602, so that the storage tray 2602 can be restricted to one side of the multimeter body 22, which is convenient for storing the connecting wire 25. When the limit bar 2615 is not in use, the limit bar 2615 is controlled to slide on the inner wall of the sliding frame 2614, and then the limit bar 2615 is slid into the inside of the first rectangular groove 2617. At this time, the rubber frame 2618 is squeezed on the surface of the limit bar 2615, so that the limit bar 2615 can be restricted to the inside of the first rectangular groove 2617, thereby preventing the limit bar 2615 from affecting the connecting wire 25 from being entangled on the inner wall of the storage tray 2602. When the protective device 27 is used, the protective cover 2701 is placed on the surface of the storage tray 2602, and then the connecting block 2703 is slid into the inside of the connecting groove 2702.Then, the L-shaped plate 2705 is slid into the interior of the positioning groove 2706, and the baffle 2708 is slid out of the storage groove 2707. The fourth spring 2710 presses the baffle 2708 away from the storage groove 2707, so that the baffle 2708 is set at the top of the L-shaped plate 2705 on the side close to the positioning groove 2706. This facilitates confining one end of the L-shaped plate 2705 to the inner wall of the positioning groove 2706. The fifth spring 2713 pulls the rectangular plate 2711 toward the L-shaped plate 2705, so that the rectangular plate 2711 is set at the top of the positioning groove 2706. This prevents the sliding of the baffle 2708 from being affected. The storage tray 2602 can then be set on the side of the multimeter body 22 through the protective cover 2701.

[0034] It should be noted that all damping rods in this case are retractable dampers that can absorb energy during the retraction and extension process.
