Abstract
The utility model discloses an easily drag suitcase of going, easily climbing stair, including the box, the box lower extreme be provided with can 360 degrees rotations the universal wheel, the bottom of box and medial surface below row are to being provided with the friction pulley, the upper end and the slider regulator of box medial surface top setting of collapsible support are connected, the lower extreme and the box lower extreme of collapsible support are connected. Be provided with the pull rod on the box. The lower extreme of collapsible support passes through the rotation axis with the box lower extreme and is connected. Collapsible support is two sections, and the rotation axis connection is passed through to two sections centres, and two sections centres of collapsible support are provided with the running wheel. The beneficial effects of the utility model are that, through increasing the pulley gear to a stablize the principle, reduce friction power can make the suitcase directly drag the line on stair of triangle -shaped is related to.
Description
Technical field
The utility model belongs to mobile storing equipment technical field, relate to a kind ofly easily to tow, the luggage case of easy stair climbing.
Background technology
Current luggage case use process in, most important two determine be exactly: 1, drag walk time too heavy.2, when stair activity, manpower is needed to begin a new line, very inconvenience.Cause too heavy main cause when dragging walking to be that casing center of gravity is excessively inclined, center of gravity can not get supporting.
Utility model content
The purpose of this utility model be to provide a kind ofly easily to tow, the luggage case of easy stair climbing, by increasing pulley gear, can the random regulating box body weight heart, increase case supports power, solution luggage case tows too heavy problem on level ground; Also add and can directly tow the pulley gear of going upstairs, go upstairs and need not begin a new line again, use more laborsaving, more convenient.
The technical scheme that the utility model adopts is, a kind ofly easily to tow, the luggage case of easy stair climbing, comprise casing, casing lower end be provided with can 360 degree rotate universal wheels, arrange to being provided with friction pulley below the bottom of casing and medial surface thereof, the upper end of retractable stand is connected with the slide block adjuster arranged above box inside face, and the lower end of retractable stand is connected with casing lower end.
Preferably, casing is provided with pull bar.
Preferably, the lower end of retractable stand is connected by rotating shaft with casing lower end.
Preferably, retractable stand is two joints, is connected in the middle of two joints by rotating shaft, is provided with castor in the middle of two joints of retractable stand.
The beneficial effects of the utility model are, by increasing pulley gear, and relate to leg-of-mutton stability principle, reducing friction, luggage case can be made directly to tow on stair.
Accompanying drawing explanation
Fig. 1 is the utility model luggage case schematic diagram.
Fig. 2 is the side view of Fig. 1.
Schematic diagram is used when Fig. 3 is stair climbing.
In figure, 1. universal wheel, 2. friction pulley, 3. castor, 4. slide block adjuster, 5. rotating shaft, 6. retractable stand, 7. casing, 8. pull bar.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind ofly easily to tow, the luggage case of easy stair climbing, structure as shown in Figure 1, 2, comprise casing 7, casing 7 is provided with pull bar 8, casing 7 lower end be provided with can 360 degree rotate universal wheels 1, arrange to being provided with friction pulley 2 below the bottom of casing 7 and medial surface thereof, the upper end of retractable stand 6 is connected with the slide block adjuster 4 arranged above casing 7 medial surface, the lower end of retractable stand 6 is connected by rotating shaft 5 with casing 7 lower end, wherein, retractable stand 6 is two joints, is connected in the middle of two joints by rotating shaft 5.
Can 360 degree rotate universal wheels 1, can draw luggage case any direction walking.Friction pulley 2 can directly tow luggage case when going upstairs and go upstairs, as shown in Figure 3.Haul pull bar 8 when going upstairs when dragging luggage case, casing 7 is in skewed, and now the friction pulley 2 of both sides at the bottom of case is just stuck on stair, effectively like this reduces frictional force, by the active force of friction pulley 2, has well promoted luggage case stairs.
As shown in Figure 2, when castor 3 is mainly used in towing, the regulating box body weight heart, makes it more laborsaving.In use castor 3, slide block adjuster 4, rotating shaft 5, retractable stand 6 are as a whole.During use, can the block of sliding downwards adjuster 4, by rotating shaft 5, put down castor 3; The not used time, to pull-up slide block adjuster 4, pack up castor 3, concordant with casing.
The utility model effectively solves two fatal large shortcomings of luggage case, one be tow heavy, two are the problems running into the bothersome efforts such as stair need manpower to begin a new line.Improve the use confidence of user to luggage case greatly.Existing luggage case is exactly almost blind area in the design about this one side of going upstairs, also heavier when towing.The utility model production technology succinctly facilitates, and device simply uses, and using function is strong.Use on level land and put down castor, as long as firmly just can tow gently, casing heeling condition self also can easily be stood, and packs up castor when not using, attractive in appearance without any impact on case.Run into stair no longer manpower begin a new line, can directly tow.Being close to is impart luggage case " secondary life ".
