Description

Technical Field

[0001] The utility model relates to the field of PDA terminals, and more specifically, to a PDA handheld terminal for collecting logistics information. Background Technique

[0002] In many industries such as logistics, warehousing, retail, and healthcare, tasks such as tracking the logistics information of items, inventory management, and recording sales data are crucial. In the past, these tasks usually required a large amount of manpower and time to be manually recorded. It was not until the emergence of PDA handheld terminals that efficient and convenient data collection and management solutions were brought to these industries. The PDA handheld terminal can directly scan the barcodes or RFID tags of items, quickly identify item information, and transmit the data to the background system in real time, realizing the full-process tracking and management of the logistics and other information of items, greatly improving the work efficiency and convenience of use.

[0003] Although the PDA terminals currently on the market are small in structure and relatively convenient to use, only a simple lanyard structure is set up for the structure to prevent the PDA terminal from accidentally falling when the handheld PDA terminal is scanned. Such a structure is not only inconvenient for the end of the lanyard to be quickly and firmly connected to the arm during actual use, but also when the staff needs to carry items with both hands at the same time, it is not convenient to place the PDA terminal, increasing the risk of the PDA terminal falling and being damaged when holding the PDA terminal and carrying items with both hands at the same time. Therefore, we propose a PDA handheld terminal for collecting logistics information to solve the above existing problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1:

[0028] Please refer to Figures 1-6, a PDA handheld terminal for logistics information collection, including a PDA terminal housing 1 and a bracelet 2. A quick-release component 3 is fixedly installed on the bracelet 2 by screws. The quick-release component 3 is provided with a card joint section 301 and a loop section 302. At the bottom of the PDA terminal housing 1 corresponding to the position of the quick-release component 3, a card joint mechanism 4 is provided, and an anti-detachment sleeve belt 5 is also fixedly installed at the bottom of the PDA terminal housing 1 by screws;

[0029] The card joint mechanism 4 includes an installation groove 401 opened at the bottom of the PDA terminal housing 1. A group of limit pieces 402 are fixedly connected inside the installation groove 401, and telescopic columns 403 are slidably connected inside a group of limit pieces 402. One end of the telescopic column 403 is connected to one side of the inner wall of the corresponding installation groove 401 through a support spring 404. A card joint cavity 405 is formed between a group of limit pieces 402. A cover plate 406 is fixedly installed at the top of the installation groove 401 by screws. Avoidance through holes are opened on the cover plate 406 and the anti-detachment sleeve belt 5 corresponding to the position of the card joint cavity 405. The card joint section 301 is detachably connected by being clamped at the other ends of a group of telescopic columns 403 inside the card joint cavity 405;

[0030] A through hole is opened on one side of the corner of the PDA terminal housing 1. A buckle ring 6 is sleeved inside the through hole. Fasteners 7 are sleeved on both the buckle ring 6 and the loop section 302. The two fasteners 7 are connected by an elastic cord 8.

[0031] The working principle of this PDA handheld terminal for logistics information collection is as follows:

[0032] When it is necessary to use the PDA terminal housing 1 of the PDA terminal to scan items, just wear the bracelet 2 on the staff's arm, and then use the two fasteners 7 and the elastic cord 8 to connect the buckle ring 6 on the PDA terminal housing 1 with the loop section 302 of the quick-release component 3. At this time, the staff's fingers can pass through the anti-detachment sleeve belt 5 and hold the PDA terminal housing 1 to scan items (the specific structure and working principle of the PDA terminal are already known and publicly available technologies, so no detailed description will be given here);

[0033] When the staff needs to carry items with both hands at the same time during scanning, they only need to move the clamping mechanism 4 at the bottom of the PDA terminal shell 1 close to the quick-release part 3 on the wristband 2, and then make the clamping joint section 301 of the quick-release part 3 close to the clamping cavity 405 through the anti-dropping belt 5 and the avoidance through hole on the cover plate 406, and then press the PDA terminal shell 1 hard, so that the clamping joint section 301 is pressed into the inside of the clamping cavity 405, and is clamped by the ends of the two telescopic columns 403 from both sides of the clamping joint section 301, so that the PDA terminal shell 1 is stably installed on the wristband 2. At this time, the staff can carry the items with both hands. Since the two telescopic columns 403 are movably connected to the inside of the installation groove 401 through the support spring 404, when the PDA terminal shell 1 needs to be used again, the PDA terminal shell 1 can be pulled outward with force to cause the clamping joint section 301 to be disconnected from the clamping connection with the ends of the two telescopic columns 403, so that the PDA terminal shell 1 is disconnected from the wristband 2, and can continue to be handheld for use.

[0034] Embodiment 2:

[0035] In view of the above embodiment 1, for further description, refer to Figure 4 The quick-release part 3 is a T-shaped structure integrally formed of stainless steel. The width of the clamping joint section 301 is equal to the width of the clamping cavity 405. A sleeve is fixedly welded on one end of the telescopic column 403 located at the connection between the telescopic column 403 and the support spring 404. One end of the support spring 404 is sleeved inside the sleeve, and one end of the support spring 404 contacts one end of the telescopic column 403 through the sleeve. A positioning column is sleeved inside the other end of the support spring 404. One end of the positioning column is fixedly welded to one side of the inner wall of the corresponding installation groove 401. The other end of the telescopic column 403 is a hemispherical structure, and the distance between the axis of the telescopic column 403 and the bottom of the inner wall of the clamping cavity 405 is greater than the distance between the axis of the telescopic column 403 and the top of the opening of the clamping cavity 405.

[0036] By setting the structure of the clamping joint section 301, it is convenient to clamp with the ends of the two telescopic columns 403 inside the clamping cavity 405. By making the width of the clamping joint section 301 equal to the width of the clamping cavity 405, the dimensional error of the connection and the probability of shaking can be reduced. The setting of the sleeve and the positioning column can improve the stability of the installation structure of the support spring 404 and reduce the probability of the support deviation after the support spring 404 is installed. By making the distance between the axis of the telescopic column 403 and the bottom of the inner wall of the clamping cavity 405 greater than the distance between the axis of the telescopic column 403 and the top of the opening of the clamping cavity 405, sufficient space can be reserved for the clamping joint section 301 to be inserted into the inside of the clamping cavity 405 to avoid interference with the clamping.

[0037] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved conceptions, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
