Description
Technical field:
The utility model relates to a kind of parts of hand buggy, is specifically a kind of roller on hand buggy.
Background technology:
Hand buggy is a kind of labor-saving tool that people use when going out shopping or travel, and is usually provided with multiple roller bottom hand buggy, to be convenient for people to pull or promote hand buggy to carry supermarket purchase or luggage, very convenient.Conventional hand buggy is after the manufacturing completes, multiple rollers bottom it are all be arranged on wheel shaft by some more scattered parts such as jump ring, bearing pin riveted joint or nuts, larger-size roller is once after installing, remove being difficult to again, this will certainly increase the packaging volume of hand buggy, and then increase traffic cost, after client buys, if do not use, store and also bother very much, only large because taking volume, in addition, roller after installation, in transportation, because superposing accumulation more than quantity, can cause part roller to be damaged by pressure unavoidably.Above-mentioned packaging volume can be solved by the mode of not installing roller when hand buggy dispatches from the factory, the technical barrier that traffic cost and roller damage, but leave client for roller is installed brings inconvenience in use to client, because jump ring, some more scattered parts such as bearing pin or nut need special instrument and could realize installing, sometimes some erection skills are also needed, complaint mood is inevitably produced when client cannot complete the normal mounting of roller, therefore, how to take into account packaging volume little, traffic cost is low, roller zero damages and these technical barriers easy for installation have become many manufacturers problem in the urgent need to address.
Utility model content:
The technical problems to be solved in the utility model is, providing a kind of when ensureing that hand buggy packaging volume is little, traffic cost is low, roller zero damages, greatly can be convenient for people to the roller on hand buggy installed.
Technical solution of the present utility model is, there is provided a kind of roller on hand buggy with following structure: comprise tire and wheel hub, wherein, also comprise by cap, spring and by the lining formed for holistic large diameter cylinder section and small diameter cylinder section, large diameter cylinder section and small diameter cylinder Duan Jun are arranged in hub inner lumen, small diameter cylinder section perisporium is provided with multiple elasticity back-off, multiple axial draw-in groove snapped in for elasticity back-off is offered in hub inner lumen, elasticity back-off withstands on the step of axial draw-in groove end, large diameter cylinder section perisporium is provided with two symmetrical axial projection, two transmission keyways inserted for axial projection are offered in hub inner lumen, axial projection offers two symmetrical radial direction through hole, large diameter cylinder section opening edge is along being provided with one for keeping off the annular shoulder block on wheel hub, large diameter cylinder section inner chamber is all arranged in by cap and spring, spring top is being pressed between cap and large diameter cylinder section intracavity bottom, by cap perisporium offering two symmetrical microscler oblique through holes, microscler oblique through hole is by outward-dipping near spring terminal, a backing pin is interspersed with in each microscler oblique through hole radial direction through hole corresponding thereto, the cross section of two radial direction through hole is the strip shape through hole that can open for two backing pins.
Roller on hand buggy described in the utility model, wherein, is provided with guiding convex tendon by cap perisporium, large diameter cylinder section inner chamber perisporium offers the direction recess inserted for guiding convex tendon.
Roller on hand buggy described in the utility model, wherein, large diameter cylinder section intracavity bottom is provided with guide section, and guide section is arranged in spring intracavity, and the diameter of guide section is slightly less than the intracavity diameter by cap.
After adopting above structure, compared with prior art, the roller of the utility model on hand buggy has the following advantages: the utility model is except comprising tire and wheel hub, also comprise by cap, spring and by the lining formed for holistic large diameter cylinder section and small diameter cylinder section, and be interspersed with a backing pin in each microscler oblique through hole radial direction through hole corresponding thereto, before dispatching from the factory, assembler only needs to be fitted together by these parts in advance, form an overall roller, without the need to this overall roller is installed on the wheel shaft of hand buggy, this is when hand buggy is packed, owing to not installing roller, so packaging volume obtains reduction, traffic cost also greatly reduces, when transport and superposition are piled up, roller is not stressed, damage rate is zero, after client buys, only need press by cap with hand, then be inserted on the wheel shaft of hand buggy, when backing pin is positioned at the annular groove place that wheel shaft one end arranges in advance, unclamp by cap, backing pin can be ordered about by cap under spring force to draw in along microscler oblique through hole, and finally snap onto in annular groove, complete installation of the present utility model, if client is for a long time with during less than hand buggy, only need again press by cap, spring pressurized shrinks, backing pin is deviate under the directional tagging of microscler oblique through hole in annular groove, then take advantage of a situation and transfer to the utility model, the dismounting of roller makes hand buggy take up room to be effectively reduced, facilitate storage.
The setting party of guiding convex tendon and direction recess press the installation of cap, also ensure that backing pin is punctured in microscler oblique through hole from radial direction through hole accurately simultaneously.
The setting of guide section avoids spring and bends when shrinking or uphold.
