Draw-bar box structure with desk or saddle in prior art is all very complicated, and cost of manufacture is high, takes up room large, and practicality is not high.
Utility model content
The utility model provides a kind of Multifunctional trolley case, simple and reasonable, with the saddle that can place the little article such as notebook, snacks beverage, can also for user, take a load off one's feet as stool.
The technical solution of the utility model is: a kind of Multifunctional trolley case, comprise casing, the back side of casing is provided with pull bar, the front of casing is also provided with case lid, the back side of described casing is provided with rack, and described rack comprises a shelf and two expansion links, and two sides of described casing are respectively arranged with opening towards the installation passage of box back surface, expansion link is fixed on to be installed in passage, and shelf is hinged between two expansion links.
The articulated manner of shelf and expansion link has multiple, most economical firm mode is: in shelf end, fix a metal shaft long compared with rack size, expansion link end is provided with hinge hole, being arranged on respectively in corresponding hinge hole of metal shaft, and at metal shaft two ends, anticreep bolt is set, to prevent metal shaft landing from hinge hole.While not using rack, expansion link is hidden in to be installed in passage, and shelf is close to box back surface, and shelf can rotate centered by metal shaft, while using rack, pulls out expansion link, and shelf upset 270 is spent to expansion link end face.
Wherein expansion link is large pipe box Minute Tubule Structures, and tubule is socketed in bassoon, and expansion link is preferably by 2～3 joints successively pipe equal in length of socket and forms.
As preferably, described shelf is provided with the flange with expansion link overlap joint away from one end of expansion link.
As preferably, be also provided with two auxiliary support bars, one end of each auxiliary support bar is connected on expansion link, and the other end is hinged on casing.
On shelf, during placing articles, as long as expansion link is enough firm, whole rack can accomplish to meet holding of most of article substantially, but while sometimes placing compared with heavy articles, larger to the infringement of expansion link, easily bends and affects result of use.Thereby auxiliary support frame is set below expansion link is good selection, although pull bar is set above expansion link, to reinforce expansion link also passable, and pull bar can be limited in the size of placing articles on shelf.
As auxiliary support bar connected mode preferably, described expansion link side or bottom have bayonet socket, auxiliary support bar inserts in this bayonet socket.Auxiliary support bar also can be hinged on expansion link, and corresponding bayonet socket is set on casing, or in hinged place, confinement block is set, and the angle between restriction auxiliary support bar and expansion link is located restriction auxiliary support bar.Auxiliary support bar is hinged on expansion link, and shortcoming is, auxiliary support bar need to be hidden in together and install in passage with expansion link, makes comparatively trouble, and uses also inconvenience.
As preferably, described installation passage extends to casing and case lid junction from box back surface, and it is the metallic conduit that is arranged on an end opening of box inside wall that passage is installed.It can be plastic conduit that passage is installed, and can be even the passage that has plastics cloth to sew up, and one of object that passage is installed is for expansion link being installed, while not using rack, expansion link being stashed.Adopt metallic conduit can make casing more firm, reach the object of reinforcing casing.
As preferably, in described case lid, be also provided with U-shaped bearing frame, this U-shaped bearing frame is towards the back side of casing and be positioned at same plane with expansion link, the end of U-shaped bearing frame and the end of expansion link against.
The two ends of U-shaped bearing frame respectively with the end of corresponding expansion link against, U-shaped concrete shape and the cross-sections match of case lid, U-shaped bearing frame and metallic conduit and expansion link form one and firmly take up frame.For the people of trip, take draw-bar box when interim stool be usually only, general bottom half is because needs are installed roller, conventionally more solid, and draw-bar box middle and upper part is softer, people takes and easily makes draw-bar box distortion or sit the article in bad draw-bar box.Had this load-bearing frame, it is more firm that draw-bar box becomes, and can not sat bad.
As preferably, the back side of described casing is also provided with snap close of at least one locking shelf.
Rack is not when being used, and expansion link can be hidden into be installed in passage, but the but state in swinging of shelf, and the snap close that therefore locking shelf is set at the back side of casing prevents that shelf from rocking.
As preferably, described snap close is to be hinged on casing with plastic sheet or the sheet metal of reversal of the natural order of things tooth, and reversal of the natural order of things tooth is stuck in the angle of shelf and flange.
The beneficial effects of the utility model are: draw-bar box simple in structure, rack takes up room little, while using, expansion link is not hidden in the interior part as load-bearing frame of casing, with regard to a shelf, be attached to box back surface, and the side used of shelf is close to casing and is protected, even if shelf is worn also wearing and tearing, be the side of not used; U-shaped bearing frame and metallic conduit and expansion link form one and firmly take up frame, take draw-bar box to sit and also can not make draw-bar box distortion when stool, have more practicality.
