[0030] See also Figure 1-Figure 6The utility model provides a technical solution: a novel PXIE portable handheld case, comprising a case body 1, a display screen 2 is arranged on the front surface of the case body 1, a connecting block 3 is fixedly installed on the outer surface of the case body 1, and the shape of the connecting block 3 is L-shaped, a first baffle 4 is arranged between the two front connecting blocks 3, the interiors of the two first baffles 4 are sleeved with a first rotating shaft 6, and both ends of the two first rotating shafts 6 are rotated to penetrate into the interior of the connecting block 3, a second baffle 5 is arranged between the two right connecting blocks 3, the interiors of the two second baffles 5 are sleeved with a second rotating shaft 10, and both ends of the two second rotating shafts 10 are rotated to penetrate into the interior of the connecting block 3, a first cavity 11 is opened inside the four front connecting blocks 3, a driving assembly is arranged inside the two left front connecting blocks 3, the right end outer surfaces of the two first rotating shafts 6 are sleeved with a first bevel gear 12, and the left end outer surfaces of the two second rotating shafts 10 are sleeved with a second bevel gear 13, the first bevel gear 12 and the second bevel gear 13 are meshed and connected, when the case body 1 is not in a state of rotation, the first bevel gear 12 is engaged with the second bevel gear 13, and the second bevel gear 13 is engaged and connected with the first bevel gear 12. When in use, the first baffle 4 and the second baffle 5 are both in a closed state, thereby shielding the display screen 2 and the test interface. When the chassis body 1 needs to be used, the two first shafts 6 are driven to rotate by operating the driving assembly. At this time, the two first baffles 4 will be opened, and the two first shafts 6 will be driven to rotate by rotating, and the two first bevel gears 12 will be driven to rotate by rotating, respectively, and the two second bevel gears 13 will be driven to rotate by rotating, and the two second shafts 10 will be driven to rotate by rotating the two second baffles 5 by rotating the two second shafts 10, so that the two second baffles 5 will no longer shield the test interface.

[0031] Furthermore, the driving assembly includes two driving worms 8, which are respectively rotatably connected in the first cavities 11 opened inside the two connecting blocks 3 on the left front side. The two driving worms 8 are arranged in a mirror image. The upper end of the upper driving worm 8 rotates to pass through the connecting block 3. The outer surfaces of the two driving worms 8 are meshed and connected with the first worm gears 7. The two first worm gears 7 are respectively sleeved on the outer surfaces of the two first rotating shafts 6. A connecting rod 9 is rotatably connected between the two connecting blocks 3 on the left front side. Both ends of the connecting rod 9 rotate to pass through the interior of the connecting block 3 and are fixedly connected to the two driving worms 8. The rotation of the connecting rod 9 is driven by rotating the upper driving worm 8. At this time, the two driving worms 8 will rotate synchronously because the two driving worms 8 are mirror images. The arrangement is such that the rotation of the two driving worm gears 8 drives the two first worm wheels 7 to rotate in the opposite direction, and the rotation of the two first worm wheels 7 drives the two first rotating shafts 6 to rotate in the opposite direction, and the rotation of the two first rotating shafts 6 drives the two first baffles 4 to rotate, so that the first baffles 4 no longer block the display screen 2, and at the same time, the rotation of the two first rotating shafts 6 can respectively drive the two first bevel gears 12 to rotate in the opposite direction, so that the two first baffles 4 are opened and the second baffle 5 is opened synchronously at the same time, and the above structure reduces the operating steps of the staff, thereby improving the efficiency of the staff in opening the first baffle 4 and the second baffle 5, saving the staff's time, and improving the flexibility and practicality of the device in use.

[0032] Furthermore, a handle 14 is provided on the upper surface of the chassis body 1, a pull rod 15 is provided on the rear surface of the chassis body 1, and a universal wheel 17 is provided on the lower side of the chassis body 1. The arrangement of the handle 14, the pull rod 15 and the universal wheel 17 greatly improves the portability of the device, making it convenient for staff to carry the chassis body 1 when traveling, while also improving the flexibility and practicality of the device.

[0033] Furthermore, a bottom plate 16 is fixedly connected to the lower surface of the chassis body 1, and a second cavity 18 is provided inside the bottom plate 16. An active worm 19 is rotatably connected inside the second cavity 18. The front end of the active worm 19 rotates and passes through the bottom plate 16. The rear end of the active worm 19 is fixedly connected to a driven worm 20. The rear end of the driven worm 20 is rotatably connected to the inner wall of the second cavity 18. The outer surfaces of the active worm 19 and the driven worm 20 are meshed with a second worm gear 21. The outer surfaces of the active worm 19 and the driven worm 20 are arranged with the opposite patterns to those of the meshing of the second worm gear 21. The interiors of the two second worm gears 21 are both sleeved with a rotating rod 22. The two ends of the two rotating rods 22 rotate and pass through the interior of the bottom plate 16. A storage groove 23 is provided on the lower surface of the bottom plate 16. The universal wheel 17 is located inside the storage groove 23. The two ends of the two rotating rods 22 rotate and pass through the interiors of the two storage grooves 23 respectively. The universal wheel 17 is sleeved on the rotating The outer surface of the moving rod 22, when the staff needs to move the chassis body 1, by rotating the active worm 19, the rotation of the active worm 19 drives the rotation of the driven worm 20. Because the textures on the surfaces of the active worm 19 and the driven worm 20 are arranged in opposite directions, the rotation of the active worm 19 and the driven worm 20 will drive the two second worm wheels 21 to rotate in the opposite direction, and the rotation of the two second worm wheels 21 will respectively drive the rotation of the two rotating rods 22, and the rotation of the two rotating rods 22 will respectively drive the rotation of the universal wheel 17, and finally the universal wheel 17 is rotated out from the inside of the storage groove 23, at which time the bottom plate 16 and the chassis body 1 will be propped up. Through the above structure, when the chassis body 1 does not need to be moved, the four universal wheels 17 can be folded up, so that the bottom plate 16 is in contact with the ground, avoiding the situation where the chassis body 1 moves or tips over due to uneven ground, and improving the stability and safety of the chassis body 1 when it is placed.

[0034] In the above embodiment, the protection of the chassis body 1 can also be improved by providing the connection block 3 .

[0035] Working principle:

[0036] When the new PXIE portable handheld case is in use, the two first rotating shafts 6 are driven to rotate by operating the driving assembly. At this time, the two first baffles 4 will be opened, and the rotation of the two first rotating shafts 6 will drive the two first bevel gears 12 to rotate. The rotation of the two first bevel gears 12 will respectively drive the two second bevel gears 13 to rotate. The rotation of the two second bevel gears 13 will drive the two second rotating shafts 10 to rotate. The rotation of the two second rotating shafts 10 will drive the two second baffles 5 to rotate, so that the two second baffles 5 will no longer block the test interface.
