[0030] The two side panels 12 each include two half side panels, the edges of which are hinged together and can be folded or unfolded. Figure 2 、 Figure 3 shown.

[0031] The top panel can be hinged to the rear panel 13, and when folded, it can be flipped backward to fit closely to the outside of the rear panel 13 or flipped downward to fit closely to the inside of the rear panel 13; it can also be set to a magnetic type, and adsorbed on the side or front of the box body 1 in the folded state.

[0032] Magnetic locking devices are provided at both side edges of the front panel 11 and the bottom panel 15 to lock the box body 1 by magnetic force after it is folded, ensuring that the various parts can fit tightly together in the folded state to avoid shaking and loosening.

[0033] When folding is required, first turn over or remove the top plate, then push the two side plates 12 inwards and fold them. Figure 2 As shown, the rear plate 13 moves toward the front plate 11 and is in close contact with it, and finally the bottom plate 15 is folded upward and is in close contact with the rear plate 13 or the top plate, as shown in FIG. Figure 3The folded box body 1 is compact and can be easily placed in a car trunk or storage room, or even carried on board an airplane.

[0034] The interior of the case 1 is also equipped with adjustable dividers 16, which can be adjusted to suit the size and shape of instruments, ensuring stable storage for most instruments. Furthermore, the case 1 is equipped with multiple pockets and compartments for convenient storage of small accessories and tools. To further enhance the practicality of the loading case, a removable tool pouch has been designed on the side of the case 1, allowing users to store frequently used tools and accessories for easy access.

[0035] The housing 1 is made of carbon fiber reinforced plastic (CFRP). This advanced material is a composite of carbon fiber and plastic resin (such as epoxy resin, polyester resin, or phenolic resin). It combines the high strength, high stiffness, and low weight of carbon fiber with the moldability of plastic resin. It has the characteristics of high strength and stiffness, low weight, corrosion resistance, low thermal expansion coefficient, and design flexibility. It meets the requirements of stability and safety, and meets the interference of high temperature, corrosive substances, high pressure and other environments on the equipment. At the same time, it is low weight to adapt to the characteristics of portable equipment that should be easy to transport.

[0036] The pull rod 2 is retractable and fixedly arranged on the front plate 11 of the box body 1. The pull rod 2 can be pulled out from the top of the box body 1, and the length of the pull rod 2 can be adjusted so that people of different heights can use it, making it convenient for users to drag and move.

[0037] The auxiliary wheel assembly 3 includes an auxiliary bracket and auxiliary wheels. The auxiliary bracket is set in the middle of the pull rod 2, and two auxiliary wheels are set at the end of the auxiliary bracket. Figure 1 The auxiliary bracket is mounted on the cross bar in the middle of the pull rod 2 through a sleeve, and the sleeve can rotate relative to the cross bar.

[0038] The auxiliary bracket can rotate relative to the pull rod 2 and can be locked in a specific position. Specifically, a locking hole is provided on the sleeve, and a plurality of positioning holes are arranged circumferentially on the cross bar. The locking hole can be aligned with any one of the positioning holes, and the locking between the two is achieved by a locking pin. Alternatively, a positioning groove can be provided on the inner circumference of the sleeve, and two or more positioning protrusions can be provided on the outer circumference of the cross bar. The positioning grooves and / or positioning protrusions are adapted to each other to achieve locking or unlocking. Of course, other locking structures in the prior art can also be used between the sleeve and the cross bar to achieve relative rotation while also being locked in a specific position.

[0039] The auxiliary bracket can be locked in at least a folding position and a working position. When in the folding position, the auxiliary bracket is close to the front plate 11. Figure 2 、 Figure 3 When in the working position, the auxiliary bracket forms a certain angle with the front plate 11, as shown in FIG. Figure 4shown.

[0040] Preferably, the auxiliary bracket includes an inner support rod and an outer support rod that are sleeved together, and the two support rods can move relative to each other. A row of through holes is provided on the outer support rod along the length direction, and a positioning ball that elastically protrudes outward is provided on the inner support rod. When the positioning ball aligns with any one of the through holes, it will protrude outward from the through hole to achieve locking between the inner support rod and the outer support rod, so that the length of the auxiliary bracket can be adjusted. Through this arrangement, the box body 1 can be pulled conveniently and smoothly when it is in a posture with the front panel 11 facing downward. Such an arrangement can meet the requirement that some equipment or instruments can only be transported with a specific side facing upward.

[0041] In a preferred embodiment, an auxiliary pull rod (not shown) is provided on the pull rod 2. The auxiliary pull rod can be tilted at a certain angle relative to the pull rod 2 and is used to pull the box body 1 when the box body 1 is in a posture with the front panel 11 facing downward. The auxiliary pull rod can be folded close to the front panel 11 at other times.

[0042] In addition, the auxiliary pull rod can be replaced with a pull rope, which is more convenient and flexible, suitable for people of different heights, and can be removed and stored separately when not in use.

[0043] The bottom of the tie rod 2 extends outward and forward, forming a bracket for mounting the front wheel assembly 4. The front wheel assembly 4 comprises a rotating shaft, a triangular wheel frame, and three wheels mounted at the three corners of the wheel frame. The wheel frame is mounted on the rotating shaft and is rotatable. This design improves stability in varying terrain conditions.

[0044] The rear wheels (5) are universal wheels with wide treads, deep treads, anti-slip materials, and locking devices. Each rear wheel (5) has an independent suspension system to absorb ground impacts, and the suspension hardness can be adjusted according to the load and ground conditions.

[0045] The rear wheel 5 may also be provided with a power assist module, with a small motor and a self-balancing system installed on the axle.

[0046] The portable transport device of this utility model adopts a low center of gravity and a wide wheelbase design to improve stability. The rear wheels can also be equipped with a power assist module, and a small motor and a self-balancing system (gyroscope system) are installed on the axle to maintain forward movement in difficult environments.

[0047] Compared to existing technologies, the portable transport device provided in this embodiment not only solves the problem of traditional carts being bulky and difficult to carry, but also provides a more convenient way for users to move the device, meeting the need to transport instruments facing upward. Furthermore, a magnetic locking device has been incorporated into the folding structure of the cart to ensure that all parts fit tightly together in the folded state, preventing shaking or loosening.

[0048] The stability design ensures the safety and reliability of the instrument during transportation. With multi-point support and locking devices, the trolley can remain stable in various complex environments, preventing damage to the instrument during transportation.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
