Description

Leather trunk Technical Field The utility model relates to the technical field of luggage cases, in particular to a leather luggage case. Background In the current travel field, leather luggage is taken as a representative product of high-quality travel equipment, the overall performance of the leather luggage directly influences the travel experience of a user, however, a plurality of technical pain points to be solved in the aspect of the design of a bottom universal wheel system exist in the current luggage. Firstly, traditional leather trunk generally adopts traditional fixed knot structure to install the bottom universal wheel, this kind of fixed mode is showing the clean and tidy of surface and realizing the removal function of suitcase at initial installation stage, but nevertheless later maintenance and change link expose serious functional limitation, after the suitcase is used for a long time, the universal wheel can inevitably appear wearing and tearing, noise increase or turn to inflexible scheduling problem, this moment the user faces the actual demand of changing the universal wheel, however, the universal wheel change flow of the vast majority suitcase in the market at present is very loaded down with trivial details, usually need with the help of professional extracting tool such as screwdriver, spanner even crow bar etc. auxiliary operation, and often need exert fairly big dynamics in the dismantlement process, more troublesome, the special design of partial suitcase bottom structure leads to fastener position masking or angle point of boring, ordinary user is difficult to pinpoint and operate in a good order, in actual maintenance scene, because lack specialized tool and maintenance experience, the user often adopts improper power demolishment mode such as prying or knocking universal wheel subassembly, this kind of operation is difficult to damage universal wheel itself, more likely to damage the suitcase bottom structure, the support structure such as violent damage, the stability of the bottom plate, the stability of the suitcase is greatly impaired, the cost of life-span is reduced, the whole structure is greatly damaged, the cost is reduced, the life-span is greatly damaged, and the cost is reduced, the life of the structure is damaged. Secondly, aiming at the technical pain points that the universal wheels cannot be replaced conveniently, partial improved products are indeed appeared on the market, the quick assembly and disassembly functions of the universal wheels are realized through innovative connection structure designs, however, the stability of the connection mechanisms is excessively sacrificed in the process of pursuing structural simplification and convenient operation of the improved products, the safety performance is obviously reduced, most simple connection structures are still capable of being represented under static display or light load conditions, once the universal wheels are applied to actual travel environments, particularly when the universal wheels are used in complex use scenes such as airport fast walking, ramp rolling and road surface unevenness, the vulnerability of the universal wheels is immediately revealed, the most typical technical defects are that the connection structures are subjected to continuous vibration and impact caused by the ground unevenness when the luggage is moved at a high speed, the loosening phenomenon is gradually generated, obvious shaking sensation and noise can be generated along with the loosening degree, more serious problems are likely to cause the universal wheels to suddenly drop in the use process, the faults are especially likely to occur when users rapidly run drive a cart or pass through uneven road surfaces, the accidental falling of the wheels can not only cause the valuable articles to be damaged, the safety and the personal safety of the universal wheels are also can be seriously damaged, the overall life is further reduced, the safety of the universal wheels are further caused, the public safety is further influenced, and the safety is further life is shortened. Disclosure of utility model (One) solving the technical problems Aiming at the problems in the prior art, the utility model provides a leather trunk to solve the technical problems in the background art. (II) technical scheme In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a leather suitcase, includes the suitcase body, the suitcase body one side can be dismantled and is equipped with the universal wheel, universal wheel one side is connected with fixing device, fixing device includes dead lever, fixed sleeve, fixed slot, control the cover, reducing board, reducing slot and fixed block, fixed sleeve fixed mounting is in suitcase body one side, dead lever fixed mounting is on the universal wheel top, the fixed sleeve can dismantle the cover and establish in the dead leve
