Description

Technical Field

[0001] This utility model relates to the field of PDA terminal technology, specifically a PDA terminal scanning port protection structure. Background Technology

[0002] PDAs, also known as handheld computers, can be divided into industrial-grade PDAs and consumer PDAs based on their use. Industrial-grade PDAs are mainly used in the industrial field. Common barcode scanners, RFID readers, POS machines, etc. can all be called PDAs. Handheld terminals have non-removable batteries. For ease of holding, current handheld terminals are equipped with handles. The back of the handheld terminal is connected to the top of the handle, and the handle is held in hand to facilitate barcode scanning.

[0003] Currently, handheld terminals require daily charging during use. However, when placed on a table, they cannot be fixed in place. In environments with high personnel movement, such as express delivery workstations, they are prone to bumping into tables, causing them to fall and be damaged. This results in poor stability and fails to meet usage requirements. Therefore, there is an urgent need for a PDA terminal scanning port protection structure to solve the above problems.

[0008] The beneficial effects of this utility model are:

[0009] This PDA terminal scanning port protection structure has the advantages of simple structure, convenient operation and good protection effect. Through the cooperation of limit block and toothed block, it can firmly fix the PDA terminal and prevent it from loosening or falling off during use.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a wedge-shaped groove is provided inside the limiting block, and the wedge-shaped block contacts the inclined surface of the wedge-shaped groove.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the inclined surface contact design of the wedge block and the wedge groove allows the user to quickly control the movement of the limit block through a simple pressing operation, thereby fixing or releasing the PDA terminal and improving the efficiency of use.

[0013] Furthermore, a slider is fixedly connected to the outside of the wedge block, and a groove is provided on the inner wall of the movable cavity, with the slider slidably connected inside the groove.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it ensures the stable sliding of the wedge block. The cooperation between the slider and the groove can limit the movement trajectory of the wedge block, allowing it to slide smoothly within the moving cavity, avoiding jamming caused by shaking or displacement, and improving the reliability and service life of the structure.

[0015] Furthermore, the base has a card slot inside, and a charging plug is fixedly installed on the inner bottom wall of the card slot. The PDA terminal is plugged into the card slot.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it combines the charging function and protection function of the PDA terminal, allowing the user to charge the PDA terminal simultaneously when it is placed in the protective structure.

[0017] Furthermore, there are two wedges, and each of the two wedges has a pressing block fixedly connected to its top.

[0018] The advantage of adopting the above-mentioned further solution is that the movement of two wedge blocks can be controlled simultaneously by pressing the block.

[0019] Furthermore, a suction cup is fixedly connected to the bottom of the base, and a card holder is fixedly connected to the top of the base.

[0020] The beneficial effects of adopting the above-mentioned further solutions are that the suction cup enhances the stability and placement flexibility of the base.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4 The present invention discloses a protection structure for the scanning port of a PDA terminal. The present invention includes a base 1 and a PDA terminal 2. The base 1 has an internal movable cavity 3. A limiting slide rod 4 is fixedly connected to the inner wall of the movable cavity 3. A sliding sleeve 5 is slidably connected to the outside of the limiting slide rod 4. A limiting block 6 is fixedly connected to the top of the sliding sleeve 5. A toothed block 7 is fixedly connected to one side of the limiting block 6 extending to the outside of the movable cavity 3. A handheld shell 10 is fitted on the outside of the PDA terminal 2. A toothed groove 11 is formed on the side wall of the handheld shell 10.

[0028] In this embodiment, in actual use, a limiting spring 8 is sleeved on the outside of the limiting slide rod 4. The elastic potential energy of the limiting spring 8 pushes the slide sleeve 5 away, so that the toothed block 7 on the limiting block 6 is engaged in the tooth groove 11, thereby preventing the handheld sleeve 10 from being pulled out and improving the stability of placement.

[0029] Specifically, refer to Figure 4The base 1 has two wedge blocks 9 connected to its interior. Each wedge block 9 has a pressing block 16 fixedly connected to its top. The pressing block 16 can control the movement of the two wedge blocks 9 simultaneously. The limiting block 6 has a wedge groove 12 inside, and the wedge block 9 contacts the inclined surface of the wedge groove 12. The wedge block 9 is fixedly connected to the outside of the wedge block 9. The movable cavity 3 has a sliding groove on its inner wall, and the sliding block 13 is slidably connected to the inside of the sliding groove.

[0030] In this embodiment, the design of the slider 13 ensures the stable sliding of the wedge block 9 in actual use. The cooperation between the slider 13 and the groove can limit the movement trajectory of the wedge block 9, allowing it to slide smoothly in the active cavity 3, avoiding jamming caused by shaking or displacement, thus improving the reliability and service life of the structure. The inclined surface contact design between the wedge block 9 and the wedge groove 12 allows the user to quickly control the movement of the limit block 6 through a simple pressing operation, thereby fixing or releasing the PDA terminal and improving the efficiency of use.

[0031] Specifically, refer to Figure 1 The base 1 has a card slot 14 inside, and a charging plug 15 is fixedly installed on the inner bottom wall of the card slot 14. The PDA terminal 2 is inserted into the card slot 14. The PDA terminal 2 has a charging port, and the charging plug 15 is inserted into the charging port, which realizes the combination of charging function and protection function of the PDA terminal. When the user places the PDA terminal in the protection structure, it can charge at the same time.

[0032] Specifically, refer to Figure 3 A suction cup 17 is fixedly connected to the bottom of the base 1, and a placement slot 18 is fixedly connected to the top of the base 1. The suction cup 17 enhances the stability and placement flexibility of the base 1. The suction cup 17 can firmly fix the base 1 to the desktop or other flat surface, preventing the scanning port of the PDA terminal 2 from being scratched due to external force and affecting the scanning function. The placement slot 18 provides additional support and positioning for the handle of the handheld case 10, making it more stable during use and also making it easier for users to pick up and put down the device.

[0033] Working principle:

[0034] The suction cup 17 firmly fixes the base 1 to the table in a suitable position. The pressing block 16 simultaneously controls the two wedge blocks 9 to move downward. The inclined surface contact design between the wedge block 9 and the wedge groove 12 causes the limiting block 6 to drive the toothed block 7 to retract into the movable cavity 3. The PDA terminal 2 is inserted into the placement slot 14, and the charging plug 15 is inserted into the charging port, realizing the combination of charging and protection functions of the PDA terminal. When the pressing block 16 is released, the elastic potential energy of the limiting spring 8 pushes the sliding sleeve 5 away, causing the limiting block 6 to move and lift the wedge block 9, which is then engaged in the toothed groove 11 by the toothed block 7, thereby fixing the PDA terminal.
