Embodiment 1

[0014] exist figure 1 , figure 2 In the first embodiment shown, the waterproof portable trolley case includes a box body 1; the front and rear rollers (not shown) and the rear row rollers 2 are respectively provided on the front and rear sides below the box body 1; the inside of the box body 1 A left-right symmetrical longitudinal cylinder is arranged on the rear side; the middle part of the longitudinal cylinder is partitioned to form an upper cylinder 101 and a lower cylinder 102, and the uppermost end of the upper cylinder 101 communicates with the uppermost end of the lower cylinder 102 through the first air pipe 3 , the lowermost end of the upper cylinder 101 communicates with the lowermost end of the lower cylinder 102 through the second air pipe 5; the upper wheel seat 20 of the rear row of rollers 2 is connected to the upwardly extending wheel rod 21, and the wheel rod 21 stretches into the lower cylinder 102, and can slide up and down along the axis of the lower cyl...

Embodiment 2

[0018] for image 3 In the second embodiment shown, the pull rod 41 is detachably connected to the upper sliding plug 1010; when the rear roller 2 is not required to extend downward, the pull rod 41 can be separated from the upper sliding plug 1010. In the process of pulling the pull rod 41 upwards, the upper sliding plug 1010 and the lower sliding plug 1020 remain motionless, which does not affect the position of the rear rollers 2 . Specifically, the detachable connection is formed by a longitudinal stud 411 fixed at the lower end of the pull rod 41 and a longitudinal screw hole 412 on the upper side of the upper sliding plug 1010, and the pull rod 41 can freely rotate around its own axis, so that travelers By manually screwing the pull rod 41, the pull rod 41 is axially connected or disassembled with the upper slide plug 1010; Provides lateral restraint and prevents tie rod 41 from being pulled upwards out of upper cylinder 101 .
