Description
Technical field
The present invention relates to a kind of roller box, particularly relate to a kind of deflection-preventing axial pull-type gear box.
Background technology
Use roller box in the process of carrying luggage, almost the width with casing is suitable due to the distance between two wheels of existing roller box.For the narrower roller box of casing width, because it lightly is easy to carry about with one, usage comparison is convenient, but the distance between two wheels of this roller box is closer, in the process that it is dragged, it is not steady that ground slightly has injustice or the application of force slightly to have, and the center of gravity of casing all can be offset, thereby cause the upset of casing.But therefore exist between light small and exquisite and its stability when being dragged of the casing of roller box and need for many years to solve the contradiction that always is not solved always.
Summary of the invention
The present invention provides a kind of deflection-preventing axial pull-type gear box that can greatly improve the stability of small-sized roller box when being dragged for solving the deficiencies in the prior art.
The scheme that solves the technology of the present invention problem is: deflection-preventing axial pull-type gear box comprises that roller, packing ring, casing, beam barrel, locating hole, rotating shaft, footstalk hole, gear, gear shaft, left footstalk, teeth groove, right footstalk, positioning screw turn-knob, staple, riveting sheet and barrier sheet consist of.
Wherein, beam barrel is a cylinder, and beam barrel is positioned at the bottom of casing and is connected with casing by staple.Middle part sprocket drive spindle in beam barrel, an end of gear shaft be arranged in beam barrel madial wall blind hole and become to rotate relation movingly with beam barrel, the other end of gear shaft is to be the gear of an integral body and concentric with gear shaft.Semi-cylindrical left footstalk and right footstalk are in beam barrel simultaneously, and become to assemble relation movingly with the madial wall of beam barrel.The plane of left footstalk and right footstalk is in contact with one another.A teeth groove is longitudinally arranged respectively on the plane of left footstalk and right footstalk, and with the tooth that matches with gear, the upper and lower half of gear is in respectively simultaneously in the teeth groove of the teeth groove of left footstalk and right footstalk and matches with tooth in teeth groove in teeth groove.The left end of left footstalk is to be holistic rotating shaft with left footstalk, and the outer end of rotating shaft is to be holistic riveting sheet with rotating shaft, and the right-hand member of right footstalk is to be holistic rotating shaft with right footstalk, and it is holistic riveting sheet that the outer end of rotating shaft also has with rotating shaft.Have respectively one to be with it holistic barrier sheet at the right-hand member of left footstalk and the left end of right footstalk.In each rotating shaft, cover has a packing ring, and cover has a roller in the rotating shaft between each packing ring and riveting sheet.Have a locating hole at the middle part of beam barrel, locating hole is a tapped through hole, and the positioning screw turn-knob is made of screw rod and flat handle, and the screw thread of the screw rod of positioning screw turn-knob and locating hole inwall cooperatively interacts.One footstalk hole is arranged on the right footstalk on barrier sheet right side, and the footstalk hole is the blind hole identical with the diameter of described locating hole and screw thread form.
before dragging roller box, first the roller with the right draws to the right, drive left footstalk and travel longitudinally left thereby rotate at the drive lower gear of right footstalk, when barrier sheet contacts with gear, the roller on the right is pulled outwardly and reaches ultimate range, this moment, the roller on the left side also was moved to ultimate range in the drive of the left footstalk of gear mesh, meanwhile, the footstalk hole overlaps with the axial line of locating hole, only need the positioning screw turn-knob is turned clockwise, when the screw rod of positioning screw turn-knob enters in the footstalk hole, left footstalk, right footstalk and gear three's relative position is locked, the distance of two rollers is just locked.Under idle state, only need the positioning screw turn-knob is rotated counterclockwise, after unlocking, two rollers are promoted in opposite directions, can again make again the distance between two rollers reach minimum.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the present invention can be when being dragged, the distance of two rollers is increased significantly, just increased the leeway of roller box gravity vertical generation skew, therefore greatly improved the stability of small-sized roller box in dragging process, avoided the situation that existing roller box overturns in dragging process to occur, more convenient to use.
2. the structure that has adopted gear and matched with the left and right arbor of teeth groove due to the present invention, when one of them roller was carried out pull, another roller was also done corresponding mobile simultaneously, therefore operates very convenient.
