Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a solar charging structure for a trolley case. Background Art

[0002] When carrying luggage on a long journey, people generally choose a suitcase with a larger capacity to load the items. The existing suitcases have a solar suitcase with a solar panel on the surface and a battery inside, which can charge the devices in the suitcase. However, the charging port or charging cable of the solar suitcase is generally located inside the case. When the devices carried by the person, such as a mobile phone, need to be charged, a gap needs to be left in the suitcase to allow the data cable to connect to the charging port in the case. The case cannot be completely closed, which is inconvenient. In addition, most suitcases are generally only equipped with universal wheels for moving the case. However, when the user needs to go up and down stairs, the case needs to be carried up and down the stairs by hand. If the case is not carried by hand, it will cause a large bump when moving from the steps, which may damage the case or the items inside. When the suitcase is moved by hand, the weight of the case and the items inside are mostly carried manually, which is inconvenient. Utility Model Content

[0026] like Figure 2 As shown, in this embodiment, an adjusting screw 440 is rotatably connected between the two ends of the slot 421, and one end of the two sliders 431 located inside the slot 421 is provided with a screw hole, and the inner walls of the two screw holes are screwed with the outer walls of the adjusting screw 440.

[0027] In this embodiment, the adjusting screw rod 440 is a positive and negative thread screw rod. By rotating the adjusting screw rod 440, the two adjacent sliders 431 can be driven to move toward or away from each other, thereby controlling the rotation range of the two support rods 430, thereby controlling the distance between the U-shaped plate 420 and the connecting plate 410. After use, the user can rotate the adjusting screw rod 440 to make the two adjacent sliders 431 move away from each other, so that the connecting plate 410 is embedded between the two arms of the U-shaped plate 420.

[0028] like Figure 3 As shown, in this embodiment, the pulling mechanism 200 includes a connecting rod 210, and both ends of the connecting rod 210 are rotatably connected to a plug plate 220, the other side of the box body 100 is fixedly connected to two connecting frames 110, and the two plug plates 220 are movably plugged into the two connecting frames 110 respectively, a threaded hole 211 is opened on the outer wall of the connecting rod 210, and the connecting rod 210 is equipped with a T-shaped rod 230, one end of the T-shaped rod 230 is fixedly connected to a threaded rod 231, and the outer wall of the threaded rod 231 is screwed with the inner wall of the threaded hole 211.

[0029] In specific implementation, when in use, the user can screw the threaded rod 231 on the T-bar 230 into the threaded hole 211, and insert the two plug plates 220 into the two connecting frames 110. When encountering steps, the user can pull the box body 100 through the T-bar 230 to control the moving speed of the box body 100. After use, the user can unscrew the threaded rod 231 out of the threaded hole 211, and store the plug plate 220 and the T-bar 230 inside the U-shaped plate 420.

[0030] like Figure 2 As shown, in the present embodiment, the fixing mechanism 300 comprises two clamping blocks 310, arc grooves 422 are provided at one end of both arms of the U-shaped plate 420, and one side of the two clamping blocks 310 is respectively slidably clamped in the inside of the two arc grooves 422, two connecting holes 423 are provided at one end of one side of the U-shaped plate 420, and the two clamping blocks 310 are respectively located at one side of the two connecting holes 423, a rotating rod 320 is fixedly connected between the two clamping blocks 310, and two limit frames 424 are fixedly connected at one end of an inner wall of the U-shaped plate 420, a pull rope 330 is arranged on one side of the rotating rod 320, two ends of the pull rope 330 respectively pass through the inside of the two limit frames 424, and both ends of the pull rope 330 are rotatably sleeved with the outer wall of the rotating rod 320, and a plastic plate 331 is fixedly bonded to the outer wall of the pull rope 330.

[0031] During specific implementation, when the box body 100 needs to stop while sliding on the step through the U-shaped plate 420, the user can manually pull the T-shaped rod 230 to stop the box body 100, and the user can use the foot to pull the pull rope 330 so that the pull rope 330 pulls the rotating rod 320 to move, so that the rotating rod 320 drives the two clamping blocks 310 to move along the adjacent arc grooves 422, so that the two clamping blocks 310 are moved out from the adjacent connecting holes 423 and clamped on the step surface, thereby assisting the box body 100 in positioning on the step. The plastic plate 331 is elastic and can prevent the pull rope 330 from being entangled.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, the arc block 450 is provided to enable the U-shaped plate 420 to move more smoothly on the step.

[0034] like Figure 2 As shown, in this embodiment, the other end of the U-shaped plate 420 is fixedly connected to an arc block 450 .

[0035] In specific implementation, when the box 100 moves on the steps by relying on the U-shaped plate 420, if the step surface length error is large, the arc block 450 can slide on the step surface using its arc surface to reduce the collision caused by direct contact between the U-shaped plate 420 and the step. The arc block 450 is made of rubber.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.

Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
