Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a detection device with an SSI signal generator for use in the field of SSI signal detection. Background Technology

[0002] SSI signal is a commonly used industrial communication interface, mainly used to transmit the position value of an absolute encoder to the controller. The SSI signal is transmitted through the RS422 physical interface and consists of two parts: clock pulses and data. The controller sends a series of clock pulses to the encoder. After receiving the clock pulses for synchronization, the encoder outputs the encoder value bit by bit, including the angle position, calibration signal, or encoder operating status.

[0003] Chinese Patent Publication No. CN219806822U discloses a wireless signal detector for a railway THDS system. This utility model uses a load-bearing column and a protective airbag. When the detector body is subjected to a vertical impact force, the reverse impact force from the ground will compress the load-bearing column. The movable column indirectly obtains liquid pressure by compressing the liquid storage bladder, thereby weakening the vertical recoil force. When the detector body is subjected to a horizontal impact force, the detector body will slide freely on the buffer plate and compress the nearby protective airbag, reducing the horizontal impact force. This reduces the external impact force on the detector body and ultimately achieves a comprehensive protection effect for the detector body.

[0004] Currently, devices for SSI signal detection can only receive and read signals from magnetostrictive displacement sensors and encoders, which means they can only receive signals but cannot transmit them. Furthermore, when in use, the detection device needs to connect to probes via multiple signal lines to collect signals. The slots used to connect the probes are mostly open to the outside and located on the detection instrument. When the detection instrument is not in use, the slots are often exposed, making them prone to dust or debris falling into them, which can lead to poor contact or connection difficulties between the detection device and the probe. Utility Model Content

[0005] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the detection device needs to be connected to the probe through a signal line when in use. However, most detection instruments on the market can only receive SSI signals but cannot send SSI signals. The slots on the top of the existing detection instruments are usually directly exposed when not in use, and dust or debris can easily fall into the slots, resulting in poor contact or connection difficulties between the detection device and the probe.

[0006] To address the aforementioned problems, this utility model provides a detection device with an SSI signal generator, comprising a detector body. The detector body includes a mounting shell, on the upper end of which is mounted a display screen and multiple buttons. Multiple slots are drilled at both the front and rear ends of the mounting shell. Protective sleeves are fitted over both the front and rear ends of the mounting shell. Anti-collision strips are fixedly connected to the upper and lower ends of the protective sleeves, and a protective frame is fixedly fitted onto the outer surfaces of the protective sleeves and anti-collision strips. A keypad is fixedly connected to the lower ends of the multiple buttons. A control mainboard is fixedly connected inside the mounting shell, and the keypad is mounted on the control mainboard. The control mainboard is equipped with... A signal generating module is provided, which is used to receive or send SSI signals. The keypad and display screen are electrically connected to the control main board. The front and rear ends of the mounting shell are provided with shielding components. The shielding components include a positioning frame located at the end of the mounting shell. The inner cavity of the positioning frame is slidably connected with a support bar. The inner bottom wall of the positioning frame is fixedly connected with two support rods. The upper end of the support bar is provided with multiple baffles that correspond to multiple slots respectively. The upper end of the baffle is fixedly connected with a sliding rod. The upper end of the sliding rod moves through the positioning frame, and a piston is fixedly sleeved on the outer surface of the sliding rod. The upper and lower ends of the positioning frame are fixedly connected with two mounting rods.

[0007] In the aforementioned detection device with an SSI signal generator, by setting a signal transmission module on the control motherboard, the problem that most devices on the market can only receive SSI signals but cannot transmit them is effectively solved. At the same time, by using a shielding component, multiple slots on the detection device can be shielded. When using a slot, the baffle can be pulled to change its position, thereby exposing the slot, which effectively prevents dust or debris from falling into the slot and effectively prevents the detection device from having poor contact with the probe or connection difficulties.

[0008] As a further improvement of this application, receiving grooves are chiseled at both ends of the support bar, and two compression springs are fixedly connected to the longitudinal inner wall of the receiving groove. The two compression springs are fixedly connected to a locking block at the end near the positioning frame, and locking grooves are chiseled at both ends of the positioning frame.

[0009] As a further improvement of this application, the upper and lower ends of the support bar are respectively attached to the baffle and the support rod, and the baffle is attached to the end of the mounting shell.

[0010] As a further improvement of this application, the ends of the two card blocks that are far apart are rounded, and the card blocks match the card slots.

[0011] As another improvement of this application, multiple baffles of different sizes completely cover adjacent slots.

[0012] As another improvement of this application, the mounting rods on the two shielding components are mirror-distributed, the longitudinal section of the mounting rods is U-shaped, and the end of the mounting rod away from the positioning frame is in contact with the mounting shell.

[0013] In summary, during practical applications, the four corners of the mounting housing can be protected by protective sleeves, anti-collision strips, and protective frames. When using the slot, the sliding rod can be pulled upwards to move the baffle upwards until the piston penetrates the positioning frame. At this point, the sliding rod is fixed, and the slot is exposed, allowing the probe to be connected to the signal line through the slot for detection. When the slot is not in use, the baffle covers the slot, effectively preventing dust or debris from falling into it. This effectively prevents poor contact or connection difficulties between the detection device and the probe. Furthermore, the transmission of the SSI signal source allows for faster identification of problems on-site and quicker problem-solving. Attached Figure Description

[0016] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0017] First implementation method: Figure 1 and Figure 2The diagram illustrates a detection device with an SSI signal generator, comprising a detector body, a mounting housing 1, a display screen 3 and multiple buttons 2 mounted on the upper end of the housing 1, and a keypad fixedly connected to the lower ends of the buttons 2. A control motherboard is fixedly connected inside the housing 1, and the keypad is mounted on the control motherboard. A signal generator module is mounted on the control motherboard, which is used to receive or transmit SSI signals. This allows for both receiving and transmitting SSI signals on a single device, reducing on-site procurement costs and effectively solving the problem that most devices on the market can only receive SSI signals but cannot transmit them. SSI signal transmission helps on-site personnel check line faults, quickly locate the fault position, and improve work efficiency. The keypad and display screen 3 are electrically connected to the control motherboard, and a microcontroller is added to implement the signal generation logic. For example, the detector body can be connected to a PLC device via a keypad. Connect the wires one by one according to the wiring sequence, and set the data bits, resolution and other parameters. Start the detector and manually adjust the output value using the multiple buttons 2 on the detector. Observe the value on the computer connected to the PLC. If the value displayed on the computer screen is consistent with the value on the detector, it means that there is no fault in the line and the PLC channel. If the value displayed on the computer screen is inconsistent with the value set on the detector, it means that there is a problem with the line or the PLC channel. This way, the root cause of the problem can be quickly identified and the problem can be solved as soon as possible. The display screen 3 makes it easy for the staff to operate the detection device. Multiple slots 4 are drilled at both the front and rear ends of the mounting shell 1. Protective sleeves 5 are fitted at both the front and rear ends of the mounting shell 1. Anti-collision strips 6 are fixedly connected to the upper and lower ends of the protective sleeves 5. The outer surfaces of the protective sleeves 5 and the anti-collision strips 6 are fixedly fitted with a protective frame 7.

[0018] When using this testing device, the four corners of the mounting shell 1 can be protected by the protective sleeve 5, the anti-collision strip 6 and the protective frame 7. The probe is connected to the signal line through the slot 4, and the testing device performs the test. The button 2 and the display screen 3 make it easy for the staff to operate the testing device.

[0019] Second implementation method: This embodiment adds a shielding component to the first embodiment, while the rest remains the same as the first embodiment.

[0020] Figure 3 , Figure 4 and Figure 6The mounting housing 1 has shielding components at both its front and rear ends. Each shielding component includes a positioning frame 8 located at one end of the mounting housing 1. A support bar 9 is slidably connected to the inner cavity of the positioning frame 8. Two support rods 10 are fixedly connected to the inner bottom wall of the positioning frame 8. Multiple baffles 11, each corresponding to a different slot 4, are located at the upper end of the support bar 9. The baffles 11 have different sizes and completely cover adjacent slots 4, effectively shielding the slots 4 and preventing external dust and impurities from entering. A sliding rod 12 is fixedly connected to the upper end of each baffle 11. The upper end of the sliding rod 12 movably passes through the positioning frame 8, and a piston 13 is fixedly fitted onto the outer surface of the sliding rod 12. When the sliding rod is pulled... At 12 o'clock, piston 13 also moves upward until piston 13 penetrates positioning frame 8. Through the friction between piston 13 and positioning frame 8, sliding rod 12 and baffle 11 are limited. Two mounting rods 14 are fixedly connected to the upper and lower ends of positioning frame 8. The upper and lower ends of support bar 9 are respectively attached to baffle 11 and support rod 10. Baffle 11 is attached to the end of mounting shell 1. Support bar 9 can support multiple baffles 11. The mounting rods 14 on the two shielding components are distributed in a mirror image. The longitudinal section of mounting rod 14 is U-shaped, and the end of mounting rod 14 away from positioning frame 8 is in contact with mounting shell 1. Multiple mounting rods 14 can be used to lock the shielding components on protective frame 7 for easy assembly and disassembly.

[0021] Figure 5 and Figure 6 As shown: Both ends of the support bar 9 are chiseled with receiving grooves 15. Two compression springs 16 are fixedly connected to the longitudinal inner wall of the receiving grooves 15. The ends of the two compression springs 16 near the positioning frame 8 are fixedly connected with a locking block 17. Both ends of the positioning frame 8 are chiseled with locking slots 18. The ends of the two locking blocks 17 that are far apart are rounded. The locking blocks 17 match the locking slots 18. When the support bar 9 contacts the support rod 10, the compression springs 16 are in a compressed state, and the locking blocks 17 are located in the receiving grooves 15. If it is necessary to expose multiple slots 4 at the same time, the support bar 9 can be pushed upward directly, so that multiple baffles 11 move upward at the same time until the locking blocks 17 move to the locking slots 18. At this time, the compression springs 16 are not under pressure and return to their original position, pushing the locking blocks 17 to move outward and through the locking slots 18, thereby limiting the support bar 9, and then supporting and limiting the multiple baffles 11, so that multiple slots 4 are exposed at the same time.

[0022] When using slot 4, the slide bar 12 can be pulled upward to move the baffle 11 upward until the piston 13 penetrates the positioning frame 8. At this time, the slide bar 12 is fixed and the slot 4 is exposed. If it is necessary to expose multiple slots 4 at the same time, the support bar 9 can be pushed upward to move multiple baffles 11 upward at the same time until the locking block 17 moves to the slot 18. At this time, the compression spring 16 is not under pressure and returns to its original position, pushing the locking block 17 outward to penetrate the slot 18, thereby limiting the support bar 9, and then supporting and limiting multiple baffles 11, so that multiple slots 4 are exposed at the same time. The probe can then be connected to the signal line through the slot 4, and the detection device will perform detection. When the slot 4 is not in use, the baffle 11 covers the slot 4 to effectively prevent dust or debris from falling into the slot 4, and effectively prevent the detection device from having poor contact with the probe or connection difficulties.

[0023] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
