Description

Technical Field

[0001] This application relates to the field of data acquisition technology, and in particular to a handheld terminal data acquisition device and acquisition method. Background Technology

[0002] On-site staff often have to fill out a lot of complicated forms and even perform manual calculations when compiling material testing data, which reduces work efficiency and has a certain impact on the accuracy of material testing.

[0003] To deepen the whole-process control of material testing, a standardized data acquisition device was developed to upload test data to the material quality supervision and management system, enabling direct connection of test data from the testing center. For example, a handheld terminal data acquisition device (publication number CN112179392A) includes a data acquisition terminal component, a connecting component, and an extension component. The data acquisition terminal component includes a terminal body, a handheld part, and a switch; the connecting component includes a sleeve and a knob. The handheld part is inserted into the sleeve, and the knob is rotated to fix the handheld part and sleeve. The operator holds the extension rod, raises the terminal body near the target area, and rotates the first rotating plate, causing the pressure plate to press the switch, activating the terminal body for data acquisition. Reversing the rotation of the first rotating plate deactivates the pressure plate, activating the terminal body and ending data acquisition. By using the extension rod, climbing to higher positions for data acquisition is no longer necessary, improving work efficiency, reducing safety hazards, and addressing the problem of existing handheld terminal data acquisition devices being inconvenient for collecting data from high locations.

[0004] However, the aforementioned existing technologies still have some problems in practical use: First, although the existing technologies can collect data from high places by using an extension pole, the extension pole is not needed at low places. On the contrary, the presence of the extension pole at low places will affect the data collection of the staff. Second, when the terminal body collects data, it takes pictures of the target through the camera module of the terminal body to collect data. However, the shooting angle of the existing technologies is fixed when collecting data. It can only be adjusted by the staff by adjusting the angle of the extension pole. At this time, the angle between the camera module and the target will be tilted, which will still affect the data collection. In addition, when collecting data on the target body, it is generally to collect data on the barcode on the side wall of the target. However, the barcode position is not the same for different targets. Some are on the side wall of the target, while others are on the top of the target. In this case, the existing technologies cannot successfully collect the barcode located on the top of the target, thus affecting the data collection. In addition, the spacing between two adjacent targets is effective. If the barcodes of the targets are on opposite sides of the two targets, the existing technologies still cannot successfully collect data.

[0005] Based on this, under the above-mentioned viewpoints, there is still room for improvement in the existing terminal data acquisition devices when collecting data. Summary of the Invention

[0006] To address the aforementioned technical problems, this application provides a handheld terminal data acquisition device and acquisition method, employing the following technical solution.

[0007] In a first aspect, a handheld terminal data acquisition device includes a terminal body and a clamping part for holding the terminal body, the clamping part comprising: The clamps are used to hold the two sides of the terminal body.

The clamping members and the strip plate are slidably connected by an elastic member, and the elastic member drives the clamping members to move towards the middle of the strip plate. The clamping component includes an L-shaped clamping plate. The vertical section of the L-shaped clamping plate is provided with an extension that connects to the elastic element. The concave surface of the L-shaped clamping plate is provided with an anti-slip pad, and the horizontal section of the L-shaped clamping plate is provided with a clamping assembly for clamping the front and rear sides of the terminal body.

[0009] Preferably, the clamping assembly includes a bidirectional lead screw, and the horizontal section of the L-shaped clamping plate facing the terminal body has clamping grooves symmetrically distributed front and back, and the clamping grooves pass through the anti-slip pads. The bidirectional lead screw passes through the two clamping grooves and is rotatably installed with the L-shaped clamping plate. A sliding block that is threadedly connected to the bidirectional lead screw is slidably arranged in the clamping groove. A clamping plate is detachably installed on the end of the sliding block away from the bidirectional lead screw, and anti-slip plates are provided on opposite sides of the two clamping plates.

[0010] Preferably, the clamp further includes a mounting plate, which is disposed on the side of the strip plate away from the terminal body. A mounting shaft is provided at the end of the mounting plate away from the strip plate, and a mounting hole is provided at the upper end of the clamping arm to rotate with the mounting shaft. An extension rod is provided on the side of the mounting plate facing the strip plate, and a C-shaped frame is provided on the end of the extension rod away from the mounting plate. The C-shaped frame is slidably mounted on the side wall of the strip hole, and two bolts are threadedly connected to the C-shaped frame.

[0011] Preferably, the connector includes a connecting plate, which is placed between the bottoms of the two clamping arms, and L-shaped extension arms are slidably provided at both ends of the connecting plate. The L-shaped extension arms are connected to the bottom of the corresponding clamping arms. A bidirectional rotating cylinder is rotatably mounted on the upper end of the connecting plate via a bracket. The bidirectional rotating cylinder has internal threads with opposite directions at both ends, and extension screws are threaded to both ends of the bidirectional rotating cylinder. The end of the extension screw facing away from the bidirectional rotating cylinder is rotatably mounted to the corresponding clamping arm.

[0012] Preferably, the gravity component includes a bidirectional telescopic rod, which is placed below two strip plates. The lower end of each strip plate is provided with an extension bar connected to the telescopic section of the bidirectional telescopic rod. Both telescopic sections of the bidirectional telescopic rod have extension rods, and the lower end of each extension rod is provided with a conical gravity block with the pointed end of the gravity block facing downwards.

[0013] Preferably, a locking device is provided on the clamping arm to lock and restrict the gravity component on the clamping arm; the locking device includes locking blocks provided at both ends of the two telescopic sections of the bidirectional telescopic rod, the locking blocks are provided with threaded holes, and the clamping arm is threadedly connected to a bolt three, and the bolt three is threadedly connected to the threaded hole.

[0014] Preferably, the clamping part further includes a third adapter, which is disposed at the lower end of the telescopic member, and the second adapter is detachably mounted with a display component, which is electrically connected to the terminal body and is used to display the data collected by the terminal body.

[0015] Preferably, the clamping arm is further provided with a limiter that restricts the rotation between the clamping arm and the mounting shaft. The limiter includes an arc-shaped groove on the clamping arm centered on the mounting shaft, and the arc-shaped groove has a T-shaped cross-section. A limiting rod is mounted on the mounting plate and is slidably disposed in the arc-shaped groove. Two limiting blocks are slidably disposed in the arc-shaped groove, and the limiting rod is located between the two limiting blocks.

First, adjust the distance between the two clamps according to the size of the terminal body through the connector so that the two clamps can clamp the terminal body tightly. S2: Adjust the length. Change the length of the telescopic component according to the target height to adapt to targets of different heights and ensure that the terminal body accurately collects target data. S3: Adjust the angle. The tilt angle of the two clamping arms is adjusted by the first adapter and the second adapter, while the gravity component ensures that the terminal body is always in a vertical state. S4: Locking angle, limiting the range of rotation between the gripper and the gripping arm by a limiter, so that the terminal body can maintain a certain tilt angle or rotate within a certain tilt angle; S5: Remote display: By setting a display component at the bottom of the telescopic component, the information collected by the terminal body can be transmitted to the display component in real time so that the staff can view it in real time.

[0018] 2. The present invention changes the distance between the first adapter and the second adapter by rotating them, and also changes the angle between the rotation directions of the first adapter and the second adapter. This allows the terminal body of the present invention to be adjusted to any angle with the assistance of the rotation between the clamping arm and the clamp, the rotation of the first adapter, the rotation of the second adapter, the change of the angle between the rotation directions of the first adapter and the second adapter, and the operator changing the tilt angle of the telescopic rod.

[0019] 3. The present invention, through the cooperation of the limiting block and the arc groove, allows the limiting rod to slide only between the two limiting blocks, which can limit the rotation angle between the clamp and the clamping arm. Furthermore, the two limiting blocks of this application can fix the limiting rod in the arc groove, so that the terminal body can rotate within a small range within a certain tilt angle, or so that the terminal body always maintains a certain tilt angle.

[0034] The following is in conjunction with the appendix Figures 1 to 13 This application will be described in further detail.

[0035] Example 1: Reference Figure 1 and Figure 2 A handheld terminal data acquisition device includes a terminal body 1 and a clamping part for holding the terminal body 1. The terminal body 1 establishes data communication with a database acquisition program to realize temporary storage of detection data and rapid binding and stable transmission of handheld terminal. The terminal body 1 and the database can be electrically connected through wired, wireless or Bluetooth connection.

[0036] To enrich the detection data acquisition capability, the terminal body 1 of this application is also equipped with a humidity sensor, a temperature sensor and a barometric pressure sensor for real-time monitoring of the target's environmental conditions. The humidity sensor, temperature sensor and barometric pressure sensor are electrically connected to the central controller (such as a PLC) in the terminal body 1 through a sensor module, so that the humidity sensor, temperature sensor and barometric pressure sensor transmit the monitored information to the central controller through the sensor module, and the central controller feeds the information back to the database.

[0037] The clamping part includes: The clamps 2 are used to clamp the two sides of the terminal body 1 to ensure that the terminal body 1 remains clamped and stable during the data collection process. Each of the two clamps 2 has a clamping arm 3 on its opposite side, and the clamping arm 3 is rotatably installed with the clamps 2, so that the two clamps 2 can drive the terminal body 1 to rotate, so that the terminal body 1 can better collect the target barcode.

[0038] Connector 4 is disposed between the lower ends of the two clamping arms 3, and connector 4 is used to adjust the distance between the two clamps 2 to adapt to terminal bodies 1 of different sizes and specifications, thereby improving the applicability of this application.

[0039] Gravity component 5 is installed between the lower ends of the two grippers 2 to ensure that the terminal body 1 is always in a vertical position. When collecting data on the barcode on the target side wall, the terminal body 1 can maintain a vertical position through gravity component 5, regardless of the state of the gripping arm 3, so as to better collect data.

[0040] An adapter is installed at the lower end of the connector 4. The adapter includes a first adapter 6 and a second adapter 7. The first adapter 6 is connected to the connector 4, and the second adapter 7 is installed at the lower end of the second adapter 7. Through the cooperation of the first adapter 6 and the second adapter 7, the clamp 2 can be adjusted to different angles to adapt to the fact that the terminal body 1 of this application can collect data when the target barcode is at the bottom or between two adjacent targets, thereby further improving the applicable environment of data collection of this application.

[0041] Telescopic component 8 is located at the lower end of the second adapter 7. The telescopic component 8 is used to adjust the extension distance of the terminal body 1. The telescopic component 8 is adjusted by rotation and telescopic movement. The staff can adjust the length of the telescopic component 8 so that the terminal body 1 can collect target data at different heights.

[0042] During operation, staff first adjust the length of the telescopic component 8 according to actual needs to adapt to target data of different heights.

[0043] When collecting data from the barcode on the target sidewall, the gripper 2, connector 4, and telescopic component 8 should be kept on the same vertical plane, such as... Figure 1 As shown in the image, no adjustment of the adapter is required at this time.

[0044] When the staff holds the telescopic component 8 to drive the terminal body 1 to collect data, the telescopic component 8 will be in an inclined state. At this time, under the action of the gravity component 5, the clamp 2 and the terminal body 1 will adaptively adjust to ensure that the terminal body 1 is in a vertical state, so that the terminal body 1 can accurately collect the barcode data on the target side wall.

[0045] When targeting the barcode on the top of the target, the angle between the connector 4 and the clamp 2 and the telescopic member 8 needs to be adjusted through the first adapter 6. For example, when the angle is 90 degrees, the barcode data on the top of the target can be collected. However, at this time, the clamp 2 causes the terminal body 1 to rotate downward under the action of the gravity member 5, which makes it impossible for the terminal body 1 to collect the barcode data on the top of the target smoothly. Therefore, this application provides a locking device 31 on the clamping arm 3 to lock and restrict the gravity member 5 on the clamping arm 3. At this time, the gravity member 5 cannot operate normally, ensuring that the terminal body 1 can successfully collect the barcode data on the top of the target.

[0046] If the target data is located between two adjacent targets and the distance between them is small, this application can use the second adapter 7 in conjunction with the first adapter 6 to adjust the angle of the terminal body 1, so as to ensure that the terminal body 1 can successfully collect the target side wall barcode data.

[0047] Furthermore, since both the first adapter 6 and the second adapter 7 can only rotate in one direction, the angle between the rotation direction of the first adapter 6 and the rotation direction of the second adapter 7 cannot be changed, thus restricting the rotation direction of the terminal body 1. Therefore, the first adapter 6 and the second adapter 7 of this application are installed by screw rotation. By rotating the first adapter 6 and the second adapter 7, the distance between them can be changed, and the angle between the rotation direction of the first adapter 6 and the rotation direction of the second adapter 7 can also be changed. This allows the terminal body 1 of this application to be adjusted to any angle with the cooperation of the rotation between the clamping arm 3 and the clamp 2, the rotation of the first adapter 6, the rotation of the second adapter 7, the change of the angle between the rotation direction of the first adapter 6 and the rotation direction of the second adapter 7, and the change of the tilt angle of the telescopic rod by the operator.

[0048] To facilitate a better understanding of this application by those skilled in the art, the following detailed description of the clamp 2, connector 4, gravity member 5, first adapter 6, second adapter 7, and telescopic member 8 of this application is provided.

[0049] See Figure 3 The clamp 2 includes a strip plate 21 with a strip hole in the middle. Clamping members 22 are symmetrically arranged at the upper and lower ends of the strip plate 21. This application clamps and secures the corner of the terminal body 1 with at least four clamping members 22, which can ensure that the terminal body 1 remains clamped and stable when collecting data.

[0050] The clamping member 22 and the strip plate 21 are slidably connected by the elastic member 23. The elastic member 23 drives the clamping member 22 to move toward the middle of the strip plate 21, so that the clamping member 22 can stably clamp the terminal body 1.

[0051] When installing the terminal body 1, the operator first pulls the clamping member 22 away from the strip plate 21 so that the terminal body 1 can be placed between the two strip plates 21. Then, the operator releases the clamping member 22 so that the clamping member 22 clamps the terminal body 1 under the drive of the elastic member 23.

[0052] Further, see Figure 4 The clamping component 22 includes an L-shaped clamping plate 221. The L-shaped clamping plate 221 can clamp the horizontal and vertical surfaces at the corner of the terminal body 1 at the same time, which has a better clamping effect. The concave surface of the L-shaped clamping plate 221 is provided with an anti-slip pad 222, which can prevent the terminal body 1 from directly contacting the L-shaped clamping plate 221.

[0053] Specifically, the anti-slip pad 222 can be a rubber block, and the end face of the rubber block that contacts the terminal body 1 is set as a rough surface to increase the friction between the L-shaped clamp 221 and the terminal body 1, thereby better clamping the terminal body 1.

[0054] The elastic element 23 includes a sliding rod 231, which is disposed on the side of the strip plate 21 facing the L-shaped clamp 221. Both ends of the sliding rod 231 are fixed to the fixed strip plate disposed on the strip plate 21. The vertical section of the L-shaped clamp 221 is provided with an extension 223 connected to the elastic element 23, and the extension 223 slides through the sliding rod 231. A spring 232 is sleeved on the sliding rod 231, and the spring 232 is located between the fixed strip plate and the extension 223. Driven by the spring 232, the extension 223 always has a pushing force to move towards the middle of the strip plate 21. That is, the L-shaped clamp 221 also has a pushing force to move towards the middle of the strip plate 21, so that the L-shaped clamp 221 can clamp the terminal body 1.

[0055] Similarly, see Figure 5 A clamping assembly 24 is provided on the horizontal section of the L-shaped clamping plate 221 for clamping the front and rear sides of the terminal body 1. Specifically, the clamping assembly 24 includes a bidirectional lead screw 241. The horizontal section of the L-shaped clamping plate 221 and the side facing the terminal body 1 are provided with symmetrically distributed clamping grooves, and the clamping grooves pass through the anti-slip pad 222. The bidirectional lead screw 241 passes through the two clamping grooves and is rotatably installed with the L-shaped clamping plate 221. A sliding block 242 that is threadedly connected to the bidirectional lead screw 241 is slidably provided in the clamping groove. A clamping plate 243 is detachably installed on the end of the sliding block 242 away from the bidirectional lead screw 241. Anti-slip plates 244 are provided on opposite sides of the two clamping plates 243. The anti-slip plates 244 are made of the same material as the anti-slip pad 222.

[0056] When installing the terminal body 1, the two sliding blocks 242 on it are moved relative to each other by turning the two-way screw 241 so that the clamping plate 243 can clamp the terminal body 1 through the anti-slip plate 244.

[0057] It should be noted that both ends of the bidirectional lead screw 241 are threaded sections, and the two threaded sections have opposite directions of rotation, so that the two sliding blocks 242 on the bidirectional lead screw 241 can move towards each other or away from each other.

[0058] In addition, the clamping plate 243 and the sliding block 242 are detachable and can be installed separately, making it easy to replace the clamping plate 243 of different lengths to ensure that the clamping plate 243 can clamp the front and rear sides of the terminal body 1 when targeting different specifications of terminal body 1.

[0059] In addition, a bolt 224 is threadedly connected to the side wall of the extension 223. When the clamping member 22 clamps the terminal body 1, the clamping member 22 can still slide on the strip plate 21 through the elastic member 23. Therefore, this application can tighten the bolt 224 so that the bolt 224 abuts against the side wall of the strip plate 21, thereby achieving a tight fixation between the extension 223 and the strip plate 21, thus limiting the sliding of the clamping member 22 on the strip plate 21 and ensuring that the terminal body 1 is always clamped by the clamping device 2.

[0060] See Figure 6 The clamp 2 also includes a mounting plate 25, which is located on the side of the bar plate 21 away from the terminal body 1. The end of the mounting plate 25 away from the bar plate 21 is provided with a mounting shaft 251. The upper end of the clamping arm 3 is provided with a mounting hole that rotatably engages with the mounting shaft 251. Through the rotational engagement of the mounting shaft 251 and the clamping arm 3, with the assistance of the gravity member 5, the terminal body 1 can maintain a vertical state regardless of the tilt angle of the telescopic member 8, ensuring the smooth collection of barcode data on the side wall of the target body.

[0061] Because the terminal body 1 has a data interface on its side wall, when a data cable needs to be connected, its strip plate 21, L-shaped clamp 221 and anti-slip pad 222 cannot affect the data connection of the terminal body 1. Therefore, the strip plate 21 of this application has a strip hole, and the L-shaped clamp 221 and anti-slip pad 222 all have a central notch, which does not hinder the connection between the terminal body 1 and the data cable.

[0062] In the above situation, if the mounting plate 25 is directly installed on the strip plate 21, it will block the strip hole. Therefore, the mounting plate 25 of this application is provided with an extension rod 252 on the side facing the strip plate 21, and the end of the extension rod 252 away from the mounting plate 25 is provided with a C-shaped frame 253. The C-shaped frame 253 is slidably set on the side wall of the strip hole, and the C-shaped frame 253 is threaded with a bolt 254. The C-shaped frame 253 is fixed to the strip plate 21 by tightening the bolt 254.

[0063] When a data cable needs to be connected to the side wall of the terminal body 1, and the mounting plate 25 blocks the connection of the data cable, the bolt 254 is turned to release the fastening between the convex frame 253 and the strip plate 21, so that the mounting plate 25 slides along the length of the strip hole through the extension rod 252 and the convex frame 253 until the mounting plate 25 no longer obstructs the connection of the data cable. At this time, the convex frame 253 is fastened to the strip plate 21 by the bolt 254.

[0064] Looking back Figure 3 The connector 4 includes a connecting plate 41, which is placed between the bottoms of the two clamping arms 3. L-shaped extension arms 42 are slidably provided on both the left and right ends of the connecting plate 41. The L-shaped extension arms 42 are connected to the bottom of the corresponding clamping arms 3. A bidirectional rotating cylinder 43 is rotatably mounted on the upper end of the connecting plate 41 via a bracket. The bidirectional rotating cylinder 43 has internal threads with opposite directions at both ends. Extension screws 44 are threaded to both the left and right ends of the bidirectional rotating cylinder 43. The end of the extension screw 44 facing away from the bidirectional rotating cylinder 43 is rotatably mounted to the corresponding clamping arm 3.

[0065] First, based on the size of the terminal body 1, the extension screw 44 is driven by turning the bidirectional rotary drum 43 to move the clamping arm 3, so as to adjust the distance between the two clamping arms 3, that is, to adjust the distance between the two clamps 2, to adapt to the size of the terminal body 1. At the same time, by setting the L-shaped extension arm 42, this application can ensure the stability of the connection between the clamping arm 3 and the connecting plate 41.

[0066] See Figure 7 The gravity component 5 includes a bidirectional telescopic rod 51, which is placed below two strip plates 21. The lower end of the strip plate 21 is provided with an extension strip 52 connected to the telescopic section of the bidirectional telescopic rod 51. Both telescopic sections of the bidirectional telescopic rod 51 have extension rods 53, and the lower end of the extension rod 53 is provided with a conical gravity block 54, with the pointed end of the gravity block 54 pointing downwards.

[0067] When the telescopic component 8 tilts and rotates, the gravity block 54 will swing downward under its own weight until the pointed cone at the lower end of the gravity block 54 is vertically downward. At this time, the gravity block 54 drives the bidirectional telescopic rod 51 to swing downward through the extension rod 53. Then, the bidirectional telescopic rod 51 drives the strip plate 21 to rotate downward through the extension bar 52. That is, at this time, both strip plates 21 rotate around the axis of the corresponding mounting shaft 251 so as to drive the terminal body 1 to rotate synchronously through the clamping component 22, so that the terminal body 1 is always on the same plane as the gravity block 54.

[0068] When the terminal body 1 needs to be tilted to collect data, this application uses a locking device 31 to lock and restrict the gravity component 5 to the clamping arm 3. Specifically, the locking device 31 includes locking blocks 311 provided at both ends of the two telescopic sections of the bidirectional telescopic rod 51. The locking blocks 311 have threaded holes, and the clamping arm 3 is threaded with bolts 312, which are threaded to the threaded holes.

[0069] First, keep the telescopic component 8 vertical so that the terminal body 1 can also remain vertical. At this time, the gravity block 54 will also remain vertical. That is, the locking blocks 311 at both ends of the bidirectional telescopic rod 51 and the clamping arm 3 are on the same vertical plane. Therefore, tighten the bolt 312 to connect it with the threaded hole. Then, the clamping arm 3 restricts the rotation of the bidirectional telescopic rod 51 by restricting the locking block 311 through the bolt 312, so that the gravity component 5 of this application is restricted on the clamping arm 3. At this time, tilting the telescopic component 8 will also tilt the terminal body 1 synchronously, so that the staff can collect the target data smoothly.

[0070] It should be noted that the bidirectional telescopic rod 51 of this application can only extend and retract in the axial direction, and the two telescopic sections of the bidirectional telescopic rod 51 will not rotate relative to the fixed section.

[0071] See Figure 7 and Figure 8 The first adapter 6 includes a steering seat 61 at the lower end of the connecting plate 41, an adapter plate 62 below the connecting plate 41, and a steering seat 63 at the upper end of the adapter plate 62. The steering seat 63 and the steering seat 61 are rotatably mounted through a rotating shaft 64, wherein the rotating shaft 64 is fixedly connected to the steering seat. The adapter plate 62 is provided with a fastener 65 that cooperates with the rotating shaft 64.

[0072] When it is necessary to adjust the tilt angle between the two clamping arms 3 through the first adapter 6, this application releases the fastener 65 from the rotating shaft 64 so that the connecting plate 41 and the adapter 62 can rotate, thereby adjusting the tilt angle between the two clamping arms 3. After the angle adjustment is completed, the fastener 65 is used to restrict the rotation between the connecting plate 41 and the adapter 62.

[0073] Furthermore, the fastener 65 includes a fastening disc 651 connected to the end of the rotating shaft 64, and the fastening disc 651 has a plurality of slots 652 evenly distributed circumferentially on the side opposite to the rotating shaft 64. The adapter plate 62 is provided with a fastening vertical plate 653, and a fastening screw 654 coaxial with the rotating shaft 64 is threadedly connected to the fastening vertical plate 653. A second fastening disc 655 is rotatably provided at the end of the fastening screw 654 facing the fastening disc 651. A plurality of locking blocks 656 that are inserted and engaged with the slots 652 are evenly distributed circumferentially at the end of the second fastening disc 655 facing the fastening disc 651.

[0074] When it is necessary to tighten the first adapter 6, tighten the fastening screw 654 so that the second fastening plate 655 moves toward the first fastening plate 651 until the locking block 656 on the second fastening plate 655 is engaged with the locking groove 652 on the first fastening plate 651. At this time, the rotation of the first rotating shaft 64 is restricted, thereby restricting the rotation adjustment of the first adapter 6.

[0075] See Figure 9 The second adapter 7 includes a disc 71, an adapter seat 72 at the lower end of the disc 71, a rotating shaft 2 on the adapter seat, an adapter plate 2 73 below the disc 71, the rotating shaft 2 is rotatably mounted on the adapter plate 2 73, and a connecting cylinder 74 connected to the telescopic member 8 is provided at the lower end of the adapter plate 2 73. A fastener 2 75 for fastening the second adapter 7 is provided on the adapter plate 2 73.

[0076] When it is necessary to adjust the tilt angle of the two clamping arms 3 through the second adapter 7, the second fastener 75 first releases the restriction on the second adapter 7. At this time, the disc 71 can rotate relative to the adapter plate 73 through the adapter seat 72 to realize the tilt angle adjustment of the two clamping arms 3. Then, the second fastener 75 is used to restrict the rotation of the second adapter 7.

[0077] It should be noted that the structure of fastener 2 75 is the same as that of fastener 1 65. The only difference is the installation position. Fastener 1 65 is installed on adapter plate 1 62 and cooperates with shaft 1 64, while fastener 2 75 is installed on adapter plate 2 73 and cooperates with shaft 2.

[0078] The lower end of the adapter plate 62 is provided with an adapter cylinder 66, the inner wall of which has an internal thread structure. The upper end of the disc 71 is provided with an adapter screw 76, and the adapter screw 76 is threadedly connected to the internal thread structure of the adapter cylinder 66. Through the threaded engagement of the adapter cylinder 66 and the adapter screw 76, the angle between the length direction of the adapter plate 62 and the length direction of the adapter plate 73 can be changed, that is, the angle between the rotation direction of the first adapter 6 and the rotation direction of the second adapter 7 can be changed, further improving the variability of the rotation angle of the terminal body 1 of this application; secondly, through the threaded engagement of the adapter cylinder 66 and the adapter screw 76, the distance between the adapter plate 62 and the adapter plate 73 can be changed, which has a length adjustment function.

[0079] See Figure 10The telescopic component 8 includes an internal threaded cylinder 81 and an external threaded rod 82. The external threaded rod 82 is installed on the upper end of the internal threaded cylinder 81. The two adjacent telescopic components 8 can be adjusted by rotation through the threaded engagement between the external threaded rod 82 and the internal threaded cylinder 81. The external threaded rod 82 at the uppermost end is threadedly connected to the connecting cylinder 74. Therefore, the rotation angle of the terminal body 1 can also be changed by rotating the external threaded rod 82 and the connecting cylinder 74.

[0080] Example 2: See Figure 11 Based on Embodiment 1, since the staff extends the height of the terminal body 1 by using the telescopic member 8, it will be inconvenient for the staff to view the data content displayed on the terminal body 1; therefore, the clamping part of this application also includes a third adapter 9, which is disposed at the lower end of the telescopic member 8, and the second adapter 7 is detachably mounted with a display component 10. The display component 10 is electrically connected to the terminal body 1, and the data collected by the terminal body 1 will be fed back to the display component 10 in a timely manner so that the staff can keep track of the data collection status in real time.

[0081] The display unit 10 includes a display body, which contains a PLC control unit that is signal-connected to the terminal body 1. The terminal body 1 transmits the collected information to the PLC control unit. The display body also has a display screen, which displays the collected information for the operator to observe the data in real time. In addition, the display body also has a button module that is signal-connected to the PLC control unit. The operator can control the terminal body 1 through the button module, which facilitates the operator's control and adjustment.

[0082] The signal connection mentioned above can be a wired connection, a wireless connection, or a Bluetooth connection.

[0083] It should be noted that the third adapter 9 and the second adapter 7 have the same structure, and the only difference is the installation position. The adapter screw 76 of the third adapter 9 is threadedly connected to the inner threaded cylinder 81 at the bottom of the telescopic component 8, and the connecting cylinder 74 of the third adapter 9 is detachably installed with the display body.

[0084] Example 3: Based on Embodiment 1, when the terminal body 1 needs to be tilted to collect target data, it is necessary to restrict the rotation of the terminal body 1 by the gravity component 5 and restrict the rotation between the clamping arm 3 and the mounting plate 25. Therefore, this application also provides a limiter 32 on the clamping arm 3 to restrict the rotation between the clamping arm 3 and the mounting shaft 251.

[0085] For details, please refer to Figure 12 and Figure 13The limiter 32 includes an arc-shaped groove 321 centered on the mounting shaft 251 on the clamping arm 3, and the cross-section of the arc-shaped groove 321 is T-shaped. A limit rod 322 is installed on the mounting plate 25 and is limited to sliding within the arc-shaped groove 321. Two limit blocks 323 are slidably arranged within the arc-shaped groove 321. The limit rod 322 is located between the two limit blocks 323. A bolt 324 is provided on the side of the clamping arm 3 away from the mounting plate 25 and within the arc-shaped groove 321. The bolt 324 is threadedly connected to the limit block 323.

[0086] By tightening bolt 324, the limiting block 323 is restricted within the arc groove 321, preventing the limiting block 323 from sliding within the arc groove 321. This allows the limiting rod 322 to slide only between the two limiting blocks 323, reducing the distance between the two limiting blocks 323. It can even restrict the limiting rod 322 to be fixed within the arc groove 321, preventing the limiting rod 322 from sliding within the arc groove 321. Consequently, the terminal body 1 can rotate within a certain tilt angle, or the terminal body 1 can always maintain a certain tilt angle.

[0087] In addition, this application also provides a handheld terminal data acquisition method, which includes the following steps: S1: Adjust the clamping. First, according to the size of the terminal body 1, adjust the distance between the two clamps 2 through the connector 4 so that the two clamps 2 can clamp the terminal body 1 tightly. S2: Adjust the length by changing the length of the telescopic component 8 according to the target height to adapt to targets of different heights and ensure that the terminal body 1 accurately collects target data. S3: Adjust the angle. The tilt angle of the two clamping arms 3 is adjusted by the first adapter 6 and the second adapter 7. At the same time, the gravity component 5 ensures that the terminal body 1 is always in a vertical state. S4: Locking angle, limiting the rotation range between the gripper 2 and the gripper arm 3 by the limiter 32, so that the terminal body 1 maintains a certain tilt angle or rotates within a certain tilt angle; S5: Remote display: By setting a display component 10 at the bottom of the telescopic component 8, the information collected by the terminal body 1 can be transmitted to the display component 10 in real time so that the staff can view it in real time.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
