Detailed description of the invention
By reference to the accompanying drawings, the utility model preferred embodiment is described in further details.
A kind of Portable draw-bar box as described in Fig. 1-5, comprise casing 1 and case lid 2, by slide fastener 4 drawing between described casing 1 and case lid 2, wherein said casing 1 side is connected by hinge plate 3 with case lid 2 side, after described casing 1, the back side is provided with pull bar 11, described casing 1 upper cross is to being provided with upper handle 12, on the left of described casing 1 or right side is longitudinally provided with side handle 13, one group of first roller 14 is also provided with on the downside of described casing 1, after described casing 1, the back side is provided with roll wheel assembly 5, described roll wheel assembly 5 comprises a pair holder 51 be arranged on casing 1 back side, the rotating shaft 52 of switching on holder 51 and a pair connector 53, described connector 53 one end is provided with adapter sleeve 531, described adapter sleeve 531 is fixedly located on rotating shaft 52, described connector 53 other end is provided with the second roller 532, after described casing 1, the back side is provided with the groove 7 put for the second roller 532, one of them holder 51 described is also provided with drive unit 6, described drive unit 6 comprises stepper motor 61, stepper motor driver 62, battery 63 and switch 64, described stepper motor 61 is electrically connected with stepper motor driver 62 and battery 63, described stepper motor driver 62 control step motor 61 driven rotary axle 52 rotates, described adapter sleeve 531 is also provided with baffle plate 5311, it is 120 degree that described baffle plate 5311 makes connector 53 rotate maximum angle.After described casing 1, the back side is upper is provided with hook 15 in pull bar 11 both sides, or hook 15 can be hooked on fender rod seat in by bus like this, prevents bottom roller from moving and pull bar is fallen down for 11 casees.The surface of described case lid 2 is provided with some reinforcements 21, and entirety strengthens the intensity of pull bar 11 casees.Be provided with a pair cushion block 22 on the downside of described case lid 2, both can have prevented pull bar 11 casees from tilting to fall down, can prevent again case lid 2 bottom friction from wearing and tearing.Described case lid 2 and casing 1 adopt pc material.This material is anti-falls, shock-resistant, waterproof and wear-resisting, and maximum characteristic comparing is light.
