Description

Technical Field

[0001] The utility model relates to the technical field of PDA for logistics, in particular to a portable PDA terminal for logistics. Background Art

[0002] As an intelligent device for data collection, processing and transmission, PDA handheld terminals can play an important role in the construction of logistics informationization. They can integrate information in the loading and unloading, sorting, packaging, distribution and other links, accelerate the integration of various information flows, and make information flow.

[0003] According to the search, Chinese patent literature, announcement number: CN216052840U, discloses a portable PDA for logistics, which is provided with a wristband longitudinally on the back of the body. When operating the PDA terminal, the hand is inserted into the wristband, which not only plays a portable role, but also prevents the PDA terminal from falling when scanning the code, causing damage to the PDA terminal; by providing concave surfaces on both sides of the body, and providing anti-slip strips in the concave surfaces, while ensuring the comfort of the PDA terminal, the friction between the PDA terminal and the hand is increased to prevent the PDA terminal from falling. However, during the use process, the terminal will inevitably fall or bump, which may easily cause damage to the internal components due to sharp objects or vibrations, and when the PDA terminal is restricted, dust may easily accumulate on the outside of the scanning head, resulting in the need to wipe the scanning head frequently during the scanning process. At the same time, long-term wiping may easily cause scratches on the lens, resulting in a reduced service life and inaccurate scanning. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a portable PDA terminal for logistics, which has a buffering and shock-absorbing effect to prevent the terminal from being bumped and thus reducing its service life. At the same time, it has an idle protection function to reduce dust pollution and the number of wiping times, thereby increasing its service life and solving the above-mentioned technical problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable PDA terminal for logistics, comprising a base, a battery is arranged on the inner side of the base, an installation cavity is opened on the inner side of the base, an adjustment component is arranged on the inner side of the installation cavity, protective components are arranged on the left and right sides of the base respectively, a scanning head is arranged on the top side of the base, a No. 1 buffer mechanism is arranged on the right side of the base, and a No. 2 buffer mechanism is arranged on the bottom side of the base.

[0006] Preferably, the adjustment assembly includes a micro bidirectional motor, a threaded rod, a threaded sleeve and a connecting seat, the left and right ends of the micro bidirectional motor are respectively fixedly installed with a threaded rod, the outer side of the threaded rod is connected to a threaded sleeve via a thread, the top side of the threaded sleeve is movably connected to a connecting seat, and the connecting seat is installed on the upper end of the outer side of the base through a rotating shaft.

[0007] Through the above technical solution, when in use, by pressing the button on the positive side of the base to start the micro bidirectional motor to drive the two sets of threaded rods to rotate, and then drive the threaded sleeve and the connecting seat to move right and rotate. At this time, the connecting seat rotates and drives the left and right plates to flip outward, thereby facilitating logistics scanning through the scanning head.

[0008] Preferably, the protective assembly includes a left side plate, a right side plate, a fixed plate and an arc sleeve, the left side plate and the right side plate are respectively fixedly installed on the top side of the connecting seat, and matching grooves are respectively opened between the left side plate and the right side plate, and the bottom sides of the left side plate and the right side plate are respectively fixedly installed with arc sleeves.

[0009] Through the above technical solution, when not in use, the micro bidirectional motor is started again to reverse, thereby driving the left and right plates to recover. At the same time, two sets of rubber protective rings are engaged on the outside of the scanning end to prevent dust, thereby avoiding the accumulation of a large amount of dust and the need to wipe it during use, which wastes time. It is also helpful to reduce the number of wiping times and avoid scratches on the scanning end that affect the scanning effect.

[0010] Preferably, the buffer mechanism No. 1 includes a limiting plate, a limiting column, a buffer plate and a rubber strip, the limiting column is sleeved on the inner side of the limiting plate, the buffer plate is fixedly mounted on one end of the limiting column, a buffer spring is arranged between the end of the limiting column away from the buffer plate and the limiting plate, and there are always two groups of buffer mechanisms No. 1, which are respectively arranged on the left and right sides of the base.

[0011] Through the above technical solution, when the left and right sides of the base collide, the buffer plate drives the limit column to slide on the inner side of the limit plate, thereby providing a buffering and shock-absorbing effect under the action of the buffer spring and multiple groups of rubber strips, thereby improving protection and service life.

[0012] Preferably, the second buffer mechanism includes a rubber block, a cavity and a plastic foam ball. The cavity is arranged on the bottom side of the base, and a rubber block is arranged on the inner side of the cavity. The rubber block has an I-shaped structure, and the space between the rubber block and the cavity is filled with plastic foam balls. Rubber protective rings are fixedly installed on the front and rear sides of the base respectively.

[0013] Through the above technical solution, when the PDA terminal falls vertically, the rubber block is squeezed and deformed. At this time, the plastic foam ball and the rubber block are used for buffering and shock absorption, thereby reducing the impact and avoiding concentrated impact to damage the PDA terminal.

[0014] Compared with the prior art, the utility model provides a portable PDA terminal for logistics, which has the following beneficial effects:

[0015] 1. The utility model starts the micro bidirectional motor by pressing the positive side button of the base to drive the two sets of threaded rods to rotate, thereby driving the threaded sleeve and the connecting seat to move right and rotate. At this time, the connecting seat rotates and drives the left and right plates to flip outward, so as to facilitate the logistics scanning work through the scanning head. When not in use, the micro bidirectional motor is started again to reverse, thereby driving the left and right plates to recover. At the same time, two sets of rubber protective rings are engaged on the outside of the scanning end to prevent dust, avoid the accumulation of a large amount of dust and the need to wipe during use, which wastes time, and is conducive to reducing the number of wiping times, avoiding scratches on the scanning end that affect the scanning effect;

[0016] 2. When the terminal falls to the ground or collides with foreign objects, the first buffer mechanism, the second buffer mechanism and the rubber protective ring are used to buffer and reduce shock on the outer side and the bottom side of the base, thereby preventing damage to the components installed on the inner side of the base due to excessive vibration or squeezing by sharp objects, thereby improving the service life and protection effect.
