Description
Technical field
The present invention relates to a kind of luggage case, especially a kind of plug-type luggage case belongs to luggage art.
Background technology
According to reports, China is maximum luggage producing country and country of consumption in the world, account for about luggage whole world yield three/
One, China's luggage industry keeps rapid growth, and the above luggage marketing industries gross output value of scale in 2015 is up to 167,400,000,000, it is contemplated that
The year two thousand twenty, scale above luggage marketing industries gross output value in China's is up to 283,600,000,000.Conservative estimation, luggage case account for luggage proportion three/
One, it is 94,500,000,000.10% share of market, prediction the year two thousand twenty output value nearly 10,000,000,000, it is seen that market prospects can are accounted for by the luggage of the present invention
It sees.Existing luggage case has generally included case body, telescopic lever and universal wheel, is widely used because its is easy to use.Travelling
Case has very long history, from only for the leather trunk of accommodating laundry, various Portable suitcases, trolley case by now, and people
Luggage case in hand in continuous evolution.It, can be with by remote control for example, having at present it has been reported that some high-tech luggage cases
Automatic moving and immediately luggage case behind；Also having can be by assembling, when the luggage case that battery truck is ridden.These high-tech
Luggage case although easily, price is expensive, it is difficult to popularity.Therefore the most commonly used or traditional drawing of people at present
Rod-type luggage case.And existing pulling-rod trunk, although it has had very long usage history, people, which seem to have practised, to be thought
Often, them are generally received.But the present inventor is already found that, the place that it has some quite unreasonable.It is to carry out first
Stress is unreasonable in the process.Such as Fig. 1（a）Shown, during implementation, thrust is in pull rod, since pull rod is located at babinet one
Side, and non-gravity place plane, therefore torque is generated in the horizontal plane, so that babinet is rotated, generates moment of flexure in vertical plane, make babinet
It is easy to topple.Either when carrying out, trolley case must be acted on by a reversed torque on hand, could keep flat
Weighing apparatus.By taking 20 inches of luggage cases as an example, it is assumed that load-carrying 23kg, universal wheel are 0.018-0.02 with ground surface friction coefficient, are taken most
Big value 0.02 then needs the reactive torque balance for applying about 650Nmm.That is it needs to spend more prodigious strength, it could well
Carry out forward.If it is by the oblique placement of babinet, is drawn and gone by pull rod, then need to bear the downward gravity of article in babinet on hand
Effect, such as Fig. 1（b）Shown, still by taking 20 inches of luggage cases as an example, load-carrying 23kg, universal wheel takes with ground surface friction coefficient
0.02, by two big equilibrium condition of system, i.e. power and equalising torque, following result is obtained by calculation：When luggage case and ground
When angle is 45 °, hand stress 80N, when luggage case and ground angle are 60 °, hand stress 140N, therefore general drawing row state
Under, human hand is subjected to the power of 80-140N, about 8-14kg object gravity, and as load-carrying increases, human hand stress increases, therefore pedestrian
It is painstaking to feel.
Meanwhile pull rod is built in box house, due to the presence of pull rod, can be flat part originally, and just have pull rod
Protrusion, such as Fig. 1（c）It is shown.This part protrudes, and just influences very much the article for placing flat class, causes the waste in many spaces.
Since it cannot entirely place article, the diameter of the pull rod corresponding space in drawbar height direction in figure in other words, such as Fig. 1
（c）It is shown, since slightly larger article needs slant setting etc., it is difficult to be utilized.According to the THICKNESS CALCULATION of babinet, if
It by taking 20 inches of luggage cases as an example, theoretically analyzes, cabinet space shared by pull rod top surface to chest bottom surface 2.5cm ranges is about
12.5%.Even if taking pull rod center line（Dotted line in figure）, with away from bottom plate 1.5cm calculate, shared by ratio also up to 7.5%.Even if
It is again larger 28 inches of luggage cases, both of the aforesaid data are respectively 8.3% and 5%.As it can be seen that usually there is the sky of 5-10% or so
Between be unable to get and efficiently use.Other than the two disadvantages, 1）The presence of pull rod, when preparation has the babinet of pull rod side,
Preparation process is more complicated than no pull rod side.Increase manufacturing cost.2）Pull rod is located at the side of babinet, passes through pull rod stretching tank
When sub-, it is also be easy to cause the fracture of pull rod, and luggage case is caused to be in half useless state.
In order to solve the problems of aforementioned trolley case, the present invention proposes a kind of side for having discarded perforation babinet completely
Formula pull rod is instead only arranged at the push-pull system of top surface, referred to as pushes and pulls case.Push-and-pull case overcomes aforementioned background art completely
In all problems existing for existing luggage case, have and carry out stablizing convenient, babinet prepares easy, and the utilization ratio of cabinet space
Many advantages, such as high.Therefore, it is contemplated that after launch, it is believed that consumer's approval can be obtained in time, win customer's welcome.Product passes through
Spend the several years post sales, it is entirely possible to be more than the market share of half.Even if accounting for the country by prediction in aforementioned background art
The market share 10%, the output value also to generate huge economic benefit, and will generate preferable social benefit close to 10,000,000,000.
