Description

Technical Field

[0001] This invention relates to the field of detection device technology, and in particular to a pressure switch sensor detection device. Background Technology

[0002] The testing device is used to test pressure switch sensors. When using the testing device, a multimeter is used in voltage mode to measure the sensor output voltage in the mV range without applying pressure. This determines whether the zero-point deviation exceeds the technical specifications. If the voltage exceeds the sensor's specifications, it indicates that the sensor's zero-point deviation is out of range. After powering on the sensor, the state of the sensor's air vent is changed by blowing air or applying air pressure. The voltage change at the sensor's output terminal is observed using the multimeter in voltage mode. By measuring the voltage change by changing the state of the sensor's air vent, the sensitivity is evaluated. If the sensor has relatively high sensitivity, this change will be more obvious. If there is no change, a more precise air pressure source may be needed to apply pressure. This method can effectively test the pressure switch sensor.

[0003] The inventors discovered in their daily work that the detection device still has at least the following problems: When using the detection device, a multimeter is used in voltage mode to measure the sensor output voltage in the mV range without applying pressure to determine whether the zero-point deviation exceeds the technical specifications. If the voltage exceeds the sensor's technical specifications, it indicates that the sensor's zero-point deviation has exceeded the range. After powering on the sensor, the state of the sensor's air vent is changed by blowing air or applying air pressure, and the voltage change at the sensor's output terminal is observed using the multimeter in voltage mode. By changing the state of the sensor's air vent and measuring the voltage change, the sensitivity is evaluated. If the sensor has relatively high sensitivity, this change will be more obvious. If there is no change, it may be necessary to use a more precise air pressure source to apply pressure. This can effectively detect pressure switch sensors. However, in actual use, because the multimeter's connection cable is relatively long, it is inconvenient to store the multimeter. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure switch sensor detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure switch sensor detection device, comprising a multimeter body, a display screen on one side of the multimeter body, an adjustment disc on one side of the multimeter body, connecting wires evenly arranged on one side of the multimeter body, and a storage device on one side of the multimeter body. The storage device includes a rotating rod, which is rotatably inserted into the back of the multimeter body. A storage tray is fixedly connected to the end of the rotating rod away from the multimeter body. Circular grooves are evenly formed on the inner wall of the storage tray, and a first rubber plate is fixedly connected to the inner wall of the circular grooves. Notches are evenly formed on one side of the first rubber plate.

[0006] The effect achieved by the above components is as follows: when using the storage device, the end of the connecting wire away from the multimeter body is inserted into the inside of the circular groove, and then the surface of the end of the connecting wire away from the multimeter body is squeezed by the inner wall of the first rubber plate. This makes it easy to restrict the end of the connecting wire away from the multimeter body to the inner wall of the storage tray, and then control the connecting wire to be wound inside the storage tray, which makes it easy to store the connecting wire.

[0007] Preferably, a connecting frame is fitted on one side of the storage tray, and a first limiting groove is formed on one side of the storage tray. A limiting rod is slidably connected to the inner wall of the first limiting groove. The end of the limiting rod away from the first limiting groove is fixedly connected to the inner wall of the connecting frame. A sliding groove is formed on the side of the connecting frame near the storage tray. A sliding frame is slidably connected to the inner wall of the sliding groove. A first damping rod is fixedly connected to one side of the inner wall of the sliding groove. The end of the first damping rod near the sliding frame is fixedly connected to one side of the sliding frame. A first spring is fitted on the surface of the first damping rod. One end of the first spring is fixedly connected to one side of the inner wall of the sliding groove. The end of the first spring near the sliding frame is fixedly connected to one side of the sliding frame. A first rectangular groove is formed on one side of the connecting frame. A rubber frame is fixedly connected to the inner wall of the first rectangular groove. The rubber frame is fitted on the surface of the limiting strip. A limiting strip is slidably connected to the inner wall of the first rectangular groove. The limiting strip is slidably connected to the inner wall of the sliding frame. A positioning block is fixedly connected to the inner wall of the sliding frame. The positioning block is slidably connected to the inner wall of the limiting strip.

[0008] The effect achieved by the above components is as follows: Under the restriction of the limiting rod, the connecting frame is manually controlled to rotate on the surface of the storage tray, and then the connecting frame is controlled to move to a suitable position. Then, the limiting strip is pulled towards the inner wall of the storage tray by the first spring. This can squeeze the limiting strip against the surface of the connecting line, thus restricting the connecting line within the inner wall of the storage tray. When the limiting strip is not in use, the limiting strip is controlled to slide on the inner wall of the sliding frame, thus sliding the limiting strip into the interior of the first rectangular groove. At this time, the rubber frame is squeezed against the surface of the limiting strip, thus restricting the limiting strip within the first rectangular groove, thereby preventing the limiting strip from affecting the connecting line and getting tangled on the inner wall of the storage tray.

[0009] Preferably, a sliding ring is slidably connected to the inner wall of the storage tray, and a second damping rod is uniformly fixedly connected to the side of the sliding ring near the multimeter body. The end of the second damping rod away from the multimeter body is fixedly connected to the side of the inner wall of the storage tray. A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to the side of the inner wall of the storage tray, and the side of the second spring near the sliding ring is fixedly connected to the side of the sliding ring. A rubber ring is fixedly connected to the side of the sliding ring away from the second damping rod.

[0010] The effect achieved by the above components is as follows: when the limiting bar is close to the inner wall of the storage tray, the second spring presses the sliding ring in the direction of the limiting bar, so that the rubber ring is pressed against one end of the limiting bar, thus restricting the limiting bar to the inner wall of the storage tray.

[0011] Preferably, a second limiting groove is provided on one side of the back of the multimeter body. A sliding rod is fixedly connected to the inner wall of the second limiting groove. A sliding block is slidably connected to the inner wall of the sliding rod. The sliding block is slidably connected to the inner wall of the second limiting groove. A rubber block is fixedly connected to the side of the sliding block away from the second limiting groove. A third spring is sleeved on the surface of the sliding rod. One end of the third spring is fixedly connected to one side of the inner wall of the second limiting groove. The end of the third spring near the sliding block is fixedly connected to one side of the sliding block. Protrusions are evenly fixedly connected to the side of the storage tray near the rotating rod.

[0012] The effect achieved by the above components is as follows: when the storage tray is rotated to the appropriate position, the sliding block is pulled towards the storage tray by the third spring, which causes the rubber block to be pressed against the side of the storage tray near the rotating rod. This allows the rubber block to be pressed against the protrusion, thus restricting the storage tray to one side of the multimeter body.

[0013] Preferably, a protective device is provided on one side of the storage tray. The protective device includes a protective sleeve. A protective sleeve is provided on one side of the multimeter body. A connecting groove is evenly opened on one side of the multimeter body. A connecting block is slidably connected to the inner wall of the connecting groove. The side of the connecting block away from the multimeter body is fixedly connected to the side of the protective sleeve. The protective sleeve is fitted on the surface of the storage tray. A second rubber plate is fixedly connected to the side of the protective sleeve away from the storage tray.

[0014] The effect achieved by the above components is as follows: when using the protective device, the protective sleeve is placed on the surface of the storage tray, and then the connecting block is slid into the inside of the connecting groove. In this way, the storage tray can be placed on one side of the multimeter body through the protective sleeve.

[0015] Preferably, a positioning groove is provided on one side of the multimeter body, an L-shaped plate is slidably connected to the inner wall of the positioning groove, the top of the L-shaped plate is fixedly connected to one side of the protective sleeve, a storage groove is provided on one side of the inner wall of the positioning groove, and a baffle is slidably connected to the inner wall of the storage groove.

[0016] The effect achieved by the above components is as follows: the connecting block is slid to the inner wall of the connecting groove, and then the L-shaped plate is slid into the interior of the positioning groove. Then the baffle is slid out of the storage groove. In this way, the baffle can be set on the top of one side of the L-shaped plate, which makes it easier to restrict one end of the L-shaped plate to the inner wall of the positioning groove.

[0017] Preferably, a third damping rod is fixedly connected to one side of the inner wall of the storage groove. The end of the third damping rod away from the storage groove is fixedly connected to the side of the baffle close to the storage groove. A fourth spring is sleeved on the surface of the third damping rod. One end of the fourth spring is fixedly connected to one side of the inner wall of the storage groove. The side of the fourth spring close to the baffle is fixedly connected to one side of the baffle.

[0018] The effect achieved by the above components is that the baffle is pressed away from the storage slot by the fourth spring, so that the baffle can be set at the top of the L-shaped plate near the positioning slot.

[0019] Preferably, a second rectangular groove is provided on one side of the L-shaped plate, a rectangular plate is slidably connected to the inner wall of the second rectangular groove, a fourth damping rod is fixedly connected to one side of the inner wall of the second rectangular groove, the end of the fourth damping rod away from the second rectangular groove is fixedly connected to one side of the rectangular plate, a fifth spring is sleeved on the surface of the fourth damping rod, one end of the fifth spring is fixedly connected to one side of the inner wall of the second rectangular groove, and the end of the fifth spring near the rectangular plate is fixedly connected to one side of the rectangular plate.

[0020] The effect achieved by the above components is that the rectangular plate is pulled towards the L-shaped plate by the fifth spring, so that the rectangular plate can be set at the top of the positioning groove, thus avoiding affecting the sliding of the baffle.

[0021] In this invention, by setting up a storage device, when using the storage device, the end of the connecting wire away from the multimeter body is inserted into the inside of the circular groove, and then the surface of the end of the connecting wire away from the multimeter body is squeezed by the inner wall of the first rubber plate. This makes it easy to restrict the end of the connecting wire away from the multimeter body to the inner wall of the storage tray, and then control the connecting wire to be wound inside the storage tray, which makes it easy to store the connecting wire.

[0030] like Figure 1-7 As shown, this invention provides a pressure switch sensor detection device. The inner wall of a large outer shell 14 is coated with epoxy 2. A switch housing 9 is disposed inside the large outer shell 14. A limit plate 5 is fixedly connected to the bottom of the switch housing 9. A first pressure rod 16 and a second pressure rod 17 are evenly arranged on the inner wall of the switch housing 9. The first pressure rod 16 and the second pressure rod 17 are connected together by a connecting spring 18. A pressure cap 19 is fitted onto the top of the second pressure rod 17. A diaphragm 6 and an upper... are connected to the bottom of the limit plate 5 by a fixing ring 13. Cover 7, diaphragm 6 has a gasket 15 on top, copper tube 21 on bottom of bottom of cover 7, cover plate 12 on bottom of bottom of inner wall of switch housing 9, small diaphragm 20 on bottom of cover plate 12, push rod 4 slidably connected in the middle of cover plate 12, spring 3 on top of push rod 4, moving contact 10 on one end of spring 3, stationary contact 11 on bottom of moving contact 10, pin 8 on one side of stationary contact 11, pin 8 slidably inserted through bottom of inner wall of switch housing 9, pin A wire 1 is provided on one side of the multimeter body 22, a display screen 23 is provided on one side of the multimeter body 22, an adjustment dial 24 is provided on one side of the multimeter body 22, connecting wires 25 are evenly arranged on one side of the multimeter body 22, and a storage device 26 is provided on one side of the multimeter body 22. When using the detection device, the voltage range of the multimeter is used to measure the voltage of the sensor output in the mV range without applying pressure to determine whether the zero point deviation exceeds the technical specification range. If the voltage exceeds the technical specification of the sensor, it indicates that the zero point deviation of the sensor has exceeded the range. After the sensor is powered on, the state of the air guide hole of the sensor is changed by blowing air or applying air pressure, and the voltage change at the output terminal of the sensor is observed using the voltage range of the multimeter. By changing the state of the air guide hole of the sensor, the voltage change is measured to evaluate the sensitivity. If the sensor has a relatively high sensitivity, this change will be more obvious. If there is no change, it may be necessary to use a more precise air pressure source to apply pressure. This can effectively detect the pressure switch sensor.

[0031] Reference Figures 3 to 5The storage device 26 includes a rotating rod 2601, which is rotatably inserted into the back of the multimeter body 22. A storage tray 2602 is fixedly connected to one end of the rotating rod 2601 away from the multimeter body 22. Circular grooves 2603 are evenly distributed on the inner wall of the storage tray 2602. A first rubber plate 2604 is fixedly connected to the inner wall of the circular grooves 2603. Notches 2605 are evenly distributed on one side of the first rubber plate 2604. When using the storage device 26, the end of the connecting wire 25 away from the multimeter body 22 is inserted into the circular groove 2603. The inner wall of the first rubber plate 2604 then presses against the surface of the end of the connecting wire 25 away from the multimeter body 22, thus confining the end of the connecting wire 25 away from the multimeter body 22 within the storage tray. The inner wall of the storage tray 2602 is used to control the connection cable 25, which is then wound around the inside of the storage tray 2602 for easy storage. A connecting frame 2610 is fitted on one side of the storage tray 2602, and a first limiting groove 2611 is opened on one side of the storage tray 2602. A limiting rod 2612 is slidably connected to the inner wall of the first limiting groove 2611. The end of the limiting rod 2612 away from the first limiting groove 2611 is fixedly connected to the inner wall of the connecting frame 2610. A sliding groove 2613 is opened on the side of the connecting frame 2610 near the storage tray 2602. A sliding frame 2614 is slidably connected to the inner wall of the sliding groove 2613. A first damping rod 2619 is fixedly connected to one side of the inner wall of the sliding groove 2613. The first damping rod 2619 is close to the sliding frame 2614. One end of the first damping rod 2619 is fixedly connected to one side of the sliding frame 2614. A first spring 2620 is sleeved on the surface of the first damping rod 2619. One end of the first spring 2620 is fixedly connected to one side of the inner wall of the slide groove 2613. The end of the first spring 2620 near the sliding frame 2614 is fixedly connected to one side of the sliding frame 2614. A first rectangular groove 2617 is opened on one side of the connecting frame 2610. A rubber frame 2618 is fixedly connected to the inner wall of the first rectangular groove 2617. The rubber frame 2618 is sleeved on the surface of the limiting strip 2615. The limiting strip 2615 is slidably connected to the inner wall of the sliding frame 2614. A positioning block 2616 is fixedly connected to the inner wall of the sliding frame 2614. Block 2616 is slidably connected to the inner wall of the limiting strip 2615. 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. Then, the connecting frame 2610 is controlled to move to a suitable position, and then the limiting strip 2615 is pulled closer to the inner wall of the storage tray 2602 by the first spring 2620. This can squeeze the limiting strip 2615 against the surface of the connecting line 25, thus restricting the connecting line 25 within the inner wall of the storage tray 2602. When the limiting strip 2615 is not in use, the limiting strip 2615 is controlled to slide on the inner wall of the sliding frame 2614, and then slides the limiting strip 2615 into the interior of the first rectangular groove 2617. At this time, the rubber frame 2618 is pressed against the surface of the limiting strip 2615.This confines the limiting strip 2615 within the first rectangular groove 2617, thereby preventing the limiting strip 2615 from affecting the connecting wire 25 and causing it to wrap around the inner wall of the storage tray 2602. A sliding ring 2608 is slidably connected to the inner wall of the storage tray 2602. A second damping rod 2606 is evenly and fixedly connected to the side of the sliding ring 2608 closest to the multimeter body 22. The end of the second damping rod 2606 away from the multimeter body 22 is fixedly connected to the side of the inner wall of the storage tray 2602. A second spring 2607 is sleeved on the surface of the second damping rod 2606. One end of the second spring 2607... The second spring 2607 is fixedly connected to one side of the inner wall of the storage tray 2602. The side of the second spring 2607 near the sliding ring 2608 is fixedly connected to one side of the sliding ring 2608. A rubber ring 2609 is fixedly connected to the side of the sliding ring 2608 away from the second damping rod 2606. When the limiting strip 2615 approaches the inner wall of the storage tray 2602, the second spring 2607 presses the sliding ring 2608 towards the limiting strip 2615. This causes the rubber ring 2609 to press against one end of the limiting strip 2615, thus confining the limiting strip 2615 to the inner wall of the storage tray 2602. A second limiting groove 2621 is provided on one side of the back of the multimeter body 22. A sliding rod 2623 is fixedly connected to the inner wall of the second limiting groove 2621. A sliding block 2622 is slidably connected to the inner wall of the sliding rod 2623. The sliding block 2622 is slidably connected to the inner wall of the second limiting groove 2621. A rubber block 2625 is fixedly connected to the side of the sliding block 2622 away from the second limiting groove 2621. A third spring 2624 is sleeved on the surface of the sliding rod 2623. One end of the third spring 2624 is fixedly connected to one side of the inner wall of the second limiting groove 2621. The third spring 2624 is close to... One end of the sliding block 2622 is fixedly connected to one side of the sliding block 2622. The storage tray 2602 has protrusions 2626 evenly fixedly connected to the side near the rotating rod 2601. When the storage tray 2602 rotates to the appropriate position, the third spring 2624 pulls the sliding block 2622 towards the storage tray 2602, causing the rubber block 2625 to press against the side of the storage tray 2602 near the rotating rod 2601. This allows the rubber block 2625 to press against the protrusions 2626, thus confining the storage tray 2602 to one side of the multimeter body 22.

[0032] Reference Figure 6 and Figure 7A protective device 27 is provided on one side of the storage tray 2602. The protective device 27 includes a protective sleeve 2701. A protective sleeve 2701 is provided on one side of the multimeter body 22. A connecting groove 2702 is evenly provided on one side of the multimeter body 22. A connecting block 2703 is slidably connected to the inner wall of the connecting groove 2702. The side of the connecting block 2703 away from the multimeter body 22 is fixedly connected to the side of the protective sleeve 2701. The protective sleeve 2701 is fitted onto the surface of the storage tray 2602. A second rubber plate 2704 is fixedly connected to the side of the protective sleeve 2701 away from the storage tray 2602. When using the protective device 27, the protective sleeve 2701 is fitted onto the surface of the storage tray 2602, and then the connecting block 2703 is slid into the connecting groove 2702. Inside, the storage tray 2602 can be placed on one side of the multimeter body 22 via the protective sleeve 2701. A positioning groove 2706 is provided on one side of the multimeter body 22. An L-shaped plate 2705 is slidably connected to the inner wall of the positioning groove 2706. The top of the L-shaped plate 2705 is fixedly connected to one side of the protective sleeve 2701. A storage groove 2707 is provided on one side of the inner wall of the positioning groove 2706. A baffle 2708 is slidably connected to the inner wall of the storage groove 2707. The connecting block 2703 is slid into the inner wall of the connecting groove 2702, thereby sliding the L-shaped plate 2705 into the positioning groove 2706. Then, the baffle 2708 is slid out of the storage groove 2707, thus placing the baffle 2708 on the top of one side of the L-shaped plate 2705. To facilitate confining one end of the L-shaped plate 2705 to the inner wall of the positioning groove 2706, a third damping rod 2709 is fixedly connected to one side of the inner wall of the receiving groove 2707. The end of the third damping rod 2709 away from the receiving groove 2707 is fixedly connected to the side of the baffle 2708 near the receiving groove 2707. A fourth spring 2710 is sleeved on the surface of the third damping rod 2709. One end of the fourth spring 2710 is fixedly connected to one side of the inner wall of the receiving groove 2707, and the side of the fourth spring 2710 near the baffle 2708 is fixedly connected to one side of the baffle 2708. By pressing the baffle 2708 away from the receiving groove 2707 through the fourth spring 2710, the baffle 2708 can be positioned on the L-shaped plate 2705 near the positioning groove 2706. On one side of the top of L-shaped plate 2705, a second rectangular groove 2714 is provided. A rectangular plate 2711 is slidably connected to the inner wall of the second rectangular groove 2714. A fourth damping rod 2712 is fixedly connected to one side of the inner wall of the second rectangular groove 2714. The end of the fourth damping rod 2712 away from the second rectangular groove 2714 is fixedly connected to one side of the rectangular plate 2711. A fifth spring 2713 is sleeved on the surface of the fourth damping rod 2712. One end of the fifth spring 2713 is fixedly connected to one side of the inner wall of the second rectangular groove 2714. The end of the fifth spring 2713 near the rectangular plate 2711 is fixedly connected to one side of the rectangular plate 2711. The fifth spring 2713 pulls the rectangular plate 2711 towards the L-shaped plate 2705.This allows the rectangular plate 2711 to be positioned at the top of the positioning groove 2706, thus avoiding interference with the sliding of the baffle 2708.

[0033] The working principle is as follows: When using the detection device, use a multimeter in voltage mode to measure the sensor output voltage in the mV range without applying pressure. Determine if the zero-point deviation exceeds the technical specifications. If the voltage exceeds the sensor's specifications, it indicates that the sensor's zero-point deviation is out of range. After powering on the sensor, change the state of the sensor's air vent by blowing air or applying air pressure, and observe the voltage change at the sensor's output using the multimeter in voltage mode. By measuring the voltage change by changing the sensor's air vent state, the sensitivity is evaluated. If the sensor has relatively high sensitivity, this change will be more obvious. If there is no change, a more precise air pressure source may be needed to apply pressure. This method can effectively test the pressure switch sensor. When the storage device 26 is in operation, the end of the connecting wire 25 furthest from the multimeter body 22 is inserted into the inside of the circular groove 2603. The inner wall of the first rubber plate 2604 then presses the surface of the end of the connecting wire 25 furthest from the multimeter body 22, thus confining this end of the connecting wire 25 to the inner wall of the storage tray 2602. The connecting wire 25 is then wound around the inside of the storage tray 2602. Under the constraint of the limiting rod 2612, the connecting frame 2610 is manually rotated on the surface of the storage tray 2602. The connecting frame 2610 is then moved to a suitable position, and the first spring 2620 pulls the limiting strip 2615 towards the inner wall of the storage tray 2602, thus pressing the limiting strip 2615 against the inner wall of the storage tray 2602. The surface of the connecting wire 25 is such that the connecting wire 25 can be confined within the inner wall of the storage tray 2602. When the limiting bar 2615 approaches the inner wall of the storage tray 2602, the second spring 2607 presses the sliding ring 2608 towards the limiting bar 2615, thus causing the rubber ring 2609 to press against one end of the limiting bar 2615, thereby confining the limiting bar 2615 within the inner wall of the storage tray 2602. When the storage tray 2602 rotates to the appropriate position, the third spring 2624 pulls the sliding block 2622 towards the storage tray 2602, thereby causing the rubber block 2625 to press against the side of the storage tray 2602 near the rotating rod 2601, thus causing the rubber block 2625 to press against the protrusion 2. On 626, this design confines the storage tray 2602 to one side of the multimeter body 22, facilitating the storage of the connecting cable 25. When the limiting strip 2615 is not in use, it slides along the inner wall of the sliding frame 2614, eventually reaching the inside of the first rectangular groove 2617. At this point, the rubber frame 2618 presses against the surface of the limiting strip 2615, thus confining it within the first rectangular groove 2617 and preventing it from interfering with the connecting cable 25 and causing it to wrap around the inner wall of the storage tray 2602. When using the protective device 27, the protective sleeve 2701 is fitted over the surface of the storage tray 2602, allowing the connecting block 2703 to slide into the connecting groove 2702.Then, the L-shaped plate 2705 is slid into 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, thus positioning the baffle 2708 on the top of the L-shaped plate 2705 near the positioning groove 2706. This helps to confine 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 towards the L-shaped plate 2705, positioning the rectangular plate 2711 on top of the positioning groove 2706. This avoids affecting the sliding of the baffle 2708. The protective sleeve 2701 then positions the storage tray 2602 on one side of the multimeter body 22.

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