DETAILED DESCRIPTION
[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 1As shown in FIG. 3 , an embodiment of the utility model proposes a PDA handheld terminal with a foldable probe, comprising a handle 1, a horizontal shell 2 is fixedly provided on the top of the handle 1, a first rotating shaft 3 is provided at one end of the horizontal shell 2, the horizontal shell 2 is movably connected to a mounting shell 4 through the first rotating shaft 3, a driving member for driving the first rotating shaft 3 to rotate is provided on the horizontal shell 2, a PDA identification probe 5 is provided at one end of the mounting shell 4 away from the horizontal shell 2 through a tilting assembly, the tilting assembly is used to change the tilt angle of the PDA identification probe 5 relative to the mounting shell 4, the tilting assembly comprises: a mounting plate 6, the mounting plate 6 is divided into two pieces, one end of the two mounting plates 6 is fixedly connected to the mounting shell 4, a second rotating shaft 7 is rotatably provided between the two mounting plates 6, one of the mounting plates 6 is provided with a first motor 8 for driving the second rotating shaft 7 to rotate, a connecting platform 9 is fixedly provided on the second rotating shaft 7, and the connecting platform 9 is fixedly connected to the PDA identification probe 5 at the side away from the mounting plate 6. When in use, the driving member is started, and the driving member drives the first rotating shaft 3 to rotate, so that the installation shell 4 and the horizontal shell 2 are at the same height. At this time, the user can hold the handle 1 of the device and extend the PDA identification probe 5 to the position to be scanned, so as to scan the RFID tag at the position. When scanning a building component with an inclination, by starting the first motor 8, the first motor 8 drives the second rotating shaft 7 to rotate, so that the angle of the PDA identification probe 5 fixedly connected to the second rotating shaft 7 through the connecting platform 9 changes to fit the inclined building component, so that the user can scan the RFID tag in the building component without twisting the arm, thereby reducing discomfort. After the scanning and identification is completed, by driving the first rotating shaft 3 to rotate, the various components of the installation shell 4 away from the end of the horizontal shell 2 are rotated toward the direction of the handle 1, so that it is folded with the handle 1, reducing the occupied space and facilitating storage.
[0018] like Figure 1 —2, further, it also includes a mounting plate 10 and a second motor 11, the second motor 11 is fixedly connected to the mounting shell 4, the output end of the second motor 11 is fixedly connected to the mounting plate 10, and the side wall of the mounting plate 10 away from the second motor 11 is fixedly connected to one end of the two mounting plates 6 away from the PDA identification probe 5. Specifically, the second motor 11 is arranged at one end of the mounting shell 4 away from the horizontal shell 2, and by starting the second motor 11, the second motor 11 drives the mounting plate 10 to rotate, so that the PDA identification probe 5 rotates along the circumferential direction of the mounting plate 10, so that the PDA identification probe 5 can fit the building components of various inclination angles and inclination directions, and has strong adaptability.
[0019] like Figure 2As shown in FIG. 3 , further, an electric push rod 12 is embedded in the interior of the mounting housing 4, and the output end of the electric push rod 12 is fixedly connected to the second motor 11. In order to scan some areas that are inconvenient for users to approach, the second motor 11 is connected to the mounting housing 4 through the electric push rod 12. When it is necessary to scan the RFID tag in the area that is inconvenient for users to approach, it is only necessary to start the electric push rod 12, so that the PDA recognition probe 5 moves in a direction away from the handle 1, thereby extending the working range of the PDA recognition probe 5.
[0020] like Figure 1 —2, further, the driving member is a third motor 13, the third motor 13 is fixedly arranged on the side wall of the mounting shell 4, and the output end of the third motor 13 is fixed to the first rotating shaft 3. Specifically, in this embodiment, the first rotating shaft 3 is fixed to the end of the mounting shell, and the first rotating shaft 3 is driven to rotate by the third motor 13, so that the mounting shell 4 can rotate around the horizontal shell 2, thereby realizing the folding and unfolding of the device as a whole. Preferably, the third motor 13 can also be arranged in the horizontal shell 2, the first bevel gear is arranged at the output end of the third motor 13, and another second bevel gear meshing with the first bevel gear is arranged on the first rotating shaft 3, so as to drive the first rotating shaft 3 to rotate, which can make the appearance of the device look more concise.
[0021] like Figure 1 As shown in FIG. 3 , further, a rubber ring 14 is provided on the side wall of the PDA recognition probe 5. When the tilt angle and orientation of the PDA recognition probe 5 change during operation, an operation error may cause the PDA recognition probe 5 to rigidly abut against the building components of the area to be scanned. By providing the rubber ring 14 on the PDA recognition probe 5, the PDA recognition probe 5 can be protected to prevent the building components from damaging the PDA recognition probe 5.
[0022] like Figure 2 As shown in FIG. 3 , further, a plurality of anti-skid depressions 15 are provided on the outer wall of the handle 1. The anti-skid depressions 15 allow the user to hold the handle 1 more tightly and prevent the hand from slipping.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
