Description

Technical Field

[0001] This utility model belongs to the field of positioning equipment technology, and in particular relates to a handheld positioning terminal. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, intelligent positioning devices have entered our daily lives and work, such as in the outdoor construction industry.

[0003] Currently, positioning terminals with antennas have the following drawbacks: some antennas are fixedly mounted on the outer casing, taking up space when carried, while others are rotatably mounted on the outer casing, making them prone to free swaying. Both of these antenna mounting methods are susceptible to breakage or impact damage during transport.

[0004] Existing patent document (publication number: CN220105298U) discloses "a handheld positioning device", the technical solution of which is that an antenna is embedded on the left side of the upper part of the instrument body, which also has the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a handheld positioning terminal with a novel structure, reliable antenna storage, convenient portability, and to prevent the antenna from being easily broken or damaged by impact during carrying.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A handheld positioning terminal includes: a housing; a circuit board and a battery, the circuit board and battery being installed inside the housing, the battery being electrically connected to the circuit board; an antenna rotatably connected to the housing, the antenna being electrically connected to the circuit board; and a SIM card, the SIM card being installed in a slot in the housing. The key feature is that the housing has a limiting base with a C-shaped slot corresponding to the antenna to restrict the antenna's free rotation. This positioning terminal has a novel structure, reliable antenna storage, and is easy to carry, preventing the antenna from easily breaking or being damaged by impact during transport due to random rotation.

[0008] Furthermore, protective sleeves are fitted around the perimeter of the shell to protect the perimeter of the shell from damage caused by lateral impacts.

[0009] Furthermore, the protective sleeve includes a collar portion and a retaining portion. The collar portion is adapted to the housing, and the retaining portion is located on the front and rear sides of the collar portion to prevent the housing from freely detaching from the collar portion. The protective sleeve is reliably installed, not easily detached, easy to disassemble, has a simple structure, and is highly practical.

[0010] Furthermore, the back of the casing has an operating port that communicates with the card slot. A cover plate is snapped onto the operating port to close it. The cover plate can be removed to insert or remove the SIM card independently without disassembling the casing, saving effort and making it convenient.

[0011] Furthermore, the cover plate has symmetrically distributed latches, and the operating port has symmetrically distributed corresponding latch holes. During installation, the tongue of the latch is inserted into the latch hole to limit and fix the cover plate, making it less likely to fall off freely. The installation is reliable, and the cover plate can be disassembled by moving it, making the operation simple.

[0012] Furthermore, the circuit board is equipped with LED lights, which are electrically connected to the circuit board. Turning on the LED lights provides illumination, allowing users to light up their surroundings and enriching the functionality.

[0013] Furthermore, the limiting base is fixed to the housing with screws, ensuring reliable fixation, easy assembly and disassembly, and flexible and convenient installation and use.

[0014] Furthermore, the shell is equipped with hooks and hook holes, which makes it easy to thread a rope through, thus improving the portability.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] 1. Rotate the antenna to lock it into the C-shaped slot of the limiting base, restricting the antenna's free rotation and preventing it from easily breaking or being damaged by impact during carrying. The antenna is not easy to fall out of the C-shaped slot, ensuring reliable storage and convenient carrying.

[0017] 2. The protective sleeve protects the four edges of the shell, preventing it from being damaged by lateral impacts.

[0018] 3. Remove the cover to install or remove the SIM card separately without opening the casing, saving effort and making it convenient.

[0019] 4. Turn on the LED lights to provide illumination, making it easier for users to light up the surrounding environment and enriching the functionality. Attached Figure Description
