Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-7 This utility model provides a technical solution: a novel trolley case, including a case body 1 and an adjustment mechanism 4. The case body 1 is made of PC material. The adjustment mechanism 4 includes a storage shell 40, an anti-slip bottom plate 41, and a square block 47. A square groove 46 is provided through the front side of the storage shell 40. Springs 403 are symmetrically installed on the upper part of the inside of the storage shell 40. A mounting plate 402 is installed at the lower end of the two springs 403. A caster wheel 404 is installed below the mounting plate 402. Sliding rods 405 are installed on the left and right sides of the mounting plate 402 respectively. The storage shell 40 has sliding grooves 401 on the left and right sides inside, and a receiving groove 42 is provided above the anti-slip base plate 41. The right wall of the receiving groove 42 has a rounded corner 43. A vertical plate 473 is installed below the square block 47. A movable column 470 is movably installed in the middle of the vertical plate 473. A rectangular shell 474 is installed at the right end of the movable column 470. Multiple rollers 475 are rotatably installed inside the rectangular shell 474. This design solves the problems of instability, slippage at the bottom, and general safety of the original device when it is used as a seat.

[0023] As the first embodiment of this utility model: a limiting groove 48 is provided on the right wall of the receiving groove 42, and a pressing plate 49 is slidably installed inside the limiting groove 48. A moving rod 44 is inserted into the right side of the anti-slip base plate 41, and a round handle 45 is installed at the right end of the moving rod 44. By setting the moving rod 44, it is easy to push the pressing plate 49, and by setting the round handle 45, it is easy to pull the moving rod 44. A return spring 471 is installed on the rear side of the vertical plate 473, and a mounting plate 472 is installed on the left end of the moving column 470. The other end of the return spring 471 is connected to the mounting plate 472. The return spring 471 is sleeved on the annular side of the moving column 470. By setting the return spring 471, the rectangular shell 474 can be made to have a certain degree of returnability. The square block 47 is connected to the mounting plate 402, and the square block 47 is slidably connected to the square groove 46. The storage shell 40 is installed above the anti-slip base plate 41. There are four adjustment mechanisms 4, which are symmetrically installed below the box body 1. By setting four adjustment mechanisms 4, the box body 1 can be well supported when multiple casters 404 are stored. A box body pull rod 2 is installed on the right side of the box body 1, which makes it easy to lift and drag the box body 1. A high-strength hook 3 is installed on the left side of the box body 1, which makes it easy to hang other luggage.

[0024] As a second embodiment of this utility model: In use, adjust the pull rod 2 of the box to a suitable length for easy dragging, then place the box 1 flat (taking one of the adjustment mechanisms 4 as an example), and then push the square block 47 to move the mounting plate 402 down, causing the two springs 403 to stretch. At this time, the mounting plate 402 drives the caster wheel 404 down and extends out of the groove in the anti-slip base plate 41. When the multiple rollers 475 contact the rounded corner 43, the multiple rollers 475 will roll and abut against the inner wall of the receiving groove 42, causing the rectangular shell 474 and the moving column 470 to push inward, thereby causing the return spring 471 to stretch. When the rectangular shell 474 moves to the limiting groove 48, it loses the inner wall of the receiving groove 42. The resistance force will enter the limiting groove 48 under the action of the return spring 471, thereby limiting the square block 47 and limiting the universal wheel 404. The other adjustment mechanisms 4 can perform this operation to fix the universal wheel 404. Then, when storing, insert the moving rod 44 into the anti-slip base plate 41 and then abut against the pressing plate 49, thereby causing the pressing plate 49 to press the rectangular shell 474, causing the rectangular shell 474 to leave the limiting groove 48. Under the action of the two springs 403, the universal wheel 404 will be reset. At this time, the box 1 can be placed upright again. Multiple anti-slip base plates 41 are in contact with the ground, which can improve the stability of the box 1 when it is placed, and thus improve the stability of people sitting on the box 1.
