Description

Technical Field

[0001] The utility model relates to the technical field of handheld terminals, and more specifically, to a transaction PDA handheld terminal with a key protection function. Background Art

[0002] There are many manufacturers of handheld terminals. Each manufacturer has a variety of names for their products, which are not unified and sometimes ambiguous. This can easily cause confusion for users and businesses. The author wants to name these handheld terminals here just to provide some convenience for users when selecting. The data collector usually refers to a handheld terminal with a barcode scanning function, but not all handheld terminals with a barcode scanning function are called data collectors.

[0003] For example, the patent document with the announcement number CN 216871128 U discloses a PDA handheld terminal with a key protection function, which relates to the technical field of handheld terminal equipment. The PDA handheld terminal with a key protection function includes a machine board, a screen and a key board are arranged on the machine board, a first baffle is arranged on the top of the machine board, an opening and closing mechanism is arranged inside the first baffle, and a protection mechanism is arranged at the bottom of the machine board. The PDA handheld terminal with a key protection function can cover the key board when the PDA handheld terminal is not in use through the cooperation of the first baffle, the second baffle, the third baffle and the opening and closing mechanism to avoid damage, which solves the problem that some existing PDA handheld terminals will wear out the keys during long-term use, causing the key display on them to be erased and affecting normal use, and the keys may also be damaged by collision when not in use, thereby causing cost losses, thereby extending the service life of the device and improving the practicality of the device.

[0004] However, when this structure is used for actual handheld key operations, since it does not provide more convenient and efficient protection operations for the key parts of the device, long-term use can easily cause wear problems on the device. When the device is subsequently repaired, it is often necessary to replace the key assembly of the device, which makes it impossible to use it for a long time. At the same time, the device cannot perform fast protective and convenient use operations and cannot meet daily use needs.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a transaction PDA handheld terminal with a key protection function. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a transaction PDA handheld terminal with a key protection function.

[0007] To achieve the above object, the utility model provides the following technical solution: comprising a docking frame, a button seat is arranged on the front of the docking frame, a storage frame is fixedly connected to the front of the button seat, a button slot is opened inside the storage frame, a button protective film is arranged inside the button slot, and one end of the docking frame is fixedly connected to a chassis;

[0008] A screen bracket, wherein the back of the docking frame is movably connected to the screen bracket, and both sides of the screen bracket are fixedly connected to sliding side frames.

[0009] Preferably, a sliding block is fixedly connected to the bottom end of the front side frame, and a screen body is arranged on the front side of the screen bracket.

[0010] Preferably, a movable shaft is provided on the surface of the chassis, and a protective flap is movably connected to the surface of the chassis via the movable shaft.

[0011] Preferably, a first magnetic ring is provided on the inner wall of the protective flip cover, and a first sealing strip is provided on the front side of the protective flip cover.

[0012] Preferably, a second magnetic attraction ring is provided on the outer surface of the button seat, and a second sealing strip is provided on the inner wall of the docking frame.

[0013] Preferably, a first close-fitting pad is provided on the back of the docking frame, and a second close-fitting pad is provided on the front of the screen bracket and the sliding side frame.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, through the docking frame, button seat, storage rack, button slot, button protective film, chassis, movable shaft and protective flap, the device can be used for safer and more reliable button protective operation. In actual use, the staff first unfolds the protective flap on the front of the docking frame along the movable shaft on the surface of the chassis to expose the entire button seat on the front of the docking frame. At this time, the staff can directly touch and press the internal button protective film from the button slot on the front of the storage rack, so as to quickly complete the operation of the button on the front of the button seat. Later, when the button protective film is wrinkled and damaged after long-term use, the button protective film can be pulled out from the top of the storage rack, and then replaced with a new button protective film and put into the button slot of the storage rack to perform protective operation on the key area of ​​the button seat, which greatly improves the service life of the buttons on the button seat and reflects the practicality of the equipment design.

[0016] 2. In the utility model, the overall use effect of the equipment is further improved through the docking frame, the button seat, the chassis, the screen bracket, the sliding side frame, the sliding card block, the screen body, the protective flap, the first magnetic attraction ring, the first sealing strip, the second magnetic attraction ring, the second sealing strip, the first tight pad and the second tight pad. In daily use, the staff can flexibly install the screen bracket on the back position on both sides of the docking frame through the sliding card blocks on both sides. At this time, the first tight pad inside the docking frame can be used to perform a stable damping docking operation with the second tight pad on the front of the screen bracket and the sliding side frame, thereby ensuring that the screen bracket can carry the screen body on the front of the screen bracket for rapid active positioning and adjustment operations. At the same time, the protective flap on the front of the docking frame can be adaptively docked and fastened with the second magnetic attraction ring and the second sealing strip of the docking frame and the button seat through the first magnetic attraction ring and the first sealing strip inside, thereby greatly improving the stability of the overall equipment during carrying and use, and reflecting the comprehensiveness of the equipment design.
