[0019] The present invention will now be described in detail with reference to the accompanying drawings.
[0020] As attached Figure 1 To be continued Figure 4 ,
[0021] Example 1:
[0022] A wrist-mounted device for a PDA includes an arc-shaped fixing plate 1, which is fixed to the wrist by a fixing strap 2. A PDA fixing bracket 3 is rotatably connected to the top of the fixing plate 1. A PDA body 4 is clamped and fixed inside the PDA fixing bracket 3. The PDA body 4 is placed inside a silicone sleeve 5. A fixing sleeve 6 is movably engaged at the front end of the silicone sleeve 5. A scanning lens and a flash are provided on the front end face of the PDA body 4. Both the silicone sleeve 5 and the fixing sleeve 6 are provided with through holes corresponding to the scanning lens and the flash. A bowl-shaped mounting sleeve 7 is fixedly fitted on the fixing sleeve 6 corresponding to the through hole of the flash. A bowl-shaped reflector 8 is embedded in the mounting sleeve 7.
[0023] In this embodiment, the PDA body 4 is shaped similarly to a common mobile phone, with a scanning lens and a flash on its front surface. The flash illuminates the surrounding area when the PDA body 4 scans codes, facilitating scanning; however, the strong light can disturb the patient's rest. This embodiment incorporates a bowl-shaped mounting sleeve 7 in front of the flash on the PDA body 4, with a bowl-shaped reflector 8 embedded inside. This reflects the light forward, minimizing its impact on the patient without interfering with scanning; the structure is similar to a flashlight's lampshade. Furthermore, the PDA body 4 can be clamped onto the PDA mounting bracket 3 for easy portability and rotation. Even without removing it, the user can raise their arm for scanning, facilitating operation.
[0024] Example 2:
[0025] Two pin sleeves 9 are symmetrically provided on both sides of the silicone sleeve 5 near its front end face. The outer side of the pin sleeve 9 is provided with a through pin hole, and the front end face of the pin sleeve 9 is provided with an insertion hole. An elastic pin piece 10 is inserted into the insertion hole. The outer side of the pin piece is provided with a protruding pin post 11. After the pin piece is inserted into the pin sleeve 9, the pin post 11 is engaged in the pin hole, and the pin piece is fixedly connected to the fixed sleeve 6.
[0026] In this embodiment, the elastic pin 10 is inserted into the pin sleeve 9 to lock it in place. This is more secure than directly putting the fixing sleeve 6 on the front end of the silicone sleeve 5, and prevents the fixing sleeve from falling off during scanning.
[0027] Example 3:
[0028] The fixing strap 2 includes a first strap 201 and a second strap 202, which are respectively fixed to both sides of the fixing plate 1. The first strap 201 and the second strap 202 are connected by Velcro. The Velcro connection is secure and can be worn on wrists of different thicknesses.
[0029] Example 4:
[0030] The bottom surface of the PDA mounting bracket 3 has a screw hole, and a rotating shaft 12 is threaded into the screw hole. The rotating shaft 12 passes through the through hole of the mounting plate 1 and is fixedly connected to the limiting plate. A first spring 13 is sleeved on the outside of the rotating shaft 12 between the mounting plate 1 and the mounting bracket. The pressure provided by the first spring 13 maintains a certain friction force to prevent the rotating shaft from losing its angle after rotation.
[0031] Example 5:
[0032] The PDA mounting bracket 3 can adopt the structure of a common clamp-type mobile phone holder, such as a common car-mounted mobile phone holder. For ease of understanding, this embodiment provides the following structure: The PDA mounting bracket 3 includes a housing 301. Two slots 302 are symmetrically provided on the rear corner of the housing 301. Two movable clamps 303 are symmetrically provided on both sides of the housing 301. Two drive buttons 304 are also symmetrically provided on both sides of the housing 301. The drive buttons 304 and the movable clamps 303 are connected by an elastic clamping component.
[0033] The elastic clamping assembly includes a first slide bar 305 fixedly connected to a movable clamping plate 303, a first slide bar 305 slidably connected to a first slide sleeve 306, a first slide bar 305 fixedly connected to a drive plate 307, a second spring 308 provided between the first slide sleeve 306 and the drive plate 307, the rear of the drive plate 307 abutting one end of a lifting rod 309, the lifting rod 309 being hinged to the housing 301, the other end of the lifting rod 309 abutting a drive rod 310, and a drive button 304 fixedly connected to one end of the drive rod 310 extending out of the housing 301.
[0034] Initially, the second spring 308 acts on the drive plate 307, causing the clamping plate 303 to clamp the PDA body 4 inward. When it is necessary to remove the PDA body 4, press the drive button 304 to rotate the lifting rod 309. The lifting rod 309 presses the drive plate 307 and the clamping plate 303 outward, thereby releasing the PDA body 4.
[0035] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
