Abstract
A trolley case with rear-mounted load-bearing wheels comprises a trolley case body and a main trundle which is fixed at the bottom of the trolley case body, an extensible rear-mounted auxiliary trundle device is arranged on the back of the trolley case body, the rear-mounted auxiliary trundle device mainly comprises an auxiliary supporting panel and an auxiliary trundle, the auxiliary supporting panel is connected with the trolley case body through an angle chain, the auxiliary supporting panel is also provided with an elastic element, the lower end face of the trolley case body is provided with an auxiliary trundle groove which is used for placing the withdrawed auxiliary trundle of the rear-mounted auxiliary trundle device in a hiding mode, and the lower end of the auxiliary supporting panel is connected with the auxiliary trundle. The arrangement of the trundle under the trolley case is changed to be more convenient, therefore users can drag or pull the trolley case with less labor; meanwhile, the simultaneous work of every trundle is fully guaranteed, accordingly the working performance of trundles is improved.
Description
Technical field
The utility model relates to the case and bag technical field, and what be specifically related to a kind ofly has a rear-mounted draw-bar box that carries wheel.
Background technology
At present, known case and bag are to be combined by the roller that casing and case bill kept on file are arranged; When luggage case was very heavy, people need overcome it owing to the weight component that tilts to produce when dragging luggage case, very painstaking and inconvenient when dragging; Simultaneously because the article of casing carrying when very heavy, if roller is few at the bottom of the case, the pressure of then sharing on each roller is very big, is easy to cause the service behaviour of roller low even damage.
The utility model content
The purpose of this utility model is the deficiency at above technology, and a kind of novel structure is provided, and easy to use have a rear-mounted draw-bar box that carries wheel;
Two fixing main castors of the utility model draw-bar box and two rear-mounted auxiliary castors that can stretch constitute double co-operation with two fixing main castors after stretching out from the groove bullet of box back surface; Because telescopic rear-mounted auxiliary castor helps the user to overcome the weight component that casing tilts to produce, and has stable force structure; And it is parallel double with fixing main castor at auxiliary castor, can keep four castors to work simultaneously under this duty, in addition, because the flexible retractility of auxiliary castor, then people can freely select two main castors to work independently or four parallel double co-operation of castor.
The utility model is achieved through the following technical solutions: have the rear-mounted draw-bar box that carries wheel, comprise the draw-bar box body and be fixed in the main castor of draw-bar box body bottom, it is characterized in that: also be provided with telescopic rear-mounted auxiliary caster device at the back of draw-bar box body; Described rear-mounted auxiliary caster device mainly is made up of supplemental support panel and auxiliary castor; The supplemental support panel is by being linked of angle chain and draw-bar box body, and also is provided with elastomeric element on the supplemental support panel; The lower surface of described draw-bar box body is provided with auxiliary castor groove, and described should auxiliary castor groove be to be used for the hiding lay down location that rear-mounted auxiliary caster device is shunk the auxiliary castor in back; The lower end of supplemental support panel is connected with auxiliary castor.
The beneficial effects of the utility model embody and are: by changing the layout of case footing wheel easily, drag or carry out draw-bar box more effortlessly, because abundant each castor that guarantees is worked simultaneously, improved the service behaviour of castor simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail;
Structural representation when Fig. 1 stretches out for the rear-mounted auxiliary caster device in the utility model;
The specific embodiment
As shown in Figure 1, have the rear-mounted draw-bar box that carries wheel, comprise draw-bar box body 1 and be fixed in the main castor 2 of draw-bar box body 1 bottom, it is characterized in that: also be provided with telescopic rear-mounted auxiliary caster device 3 at the back of draw-bar box body 1; Described rear-mounted auxiliary caster device 3 mainly is made up of supplemental support panel 31 and auxiliary castor 32; Supplemental support panel 31 is that the lower end by angle chain and draw-bar box body 1 is linked, and also is provided with elastomeric element 33 on the supplemental support panel 31; Also be provided with an auxiliary castor groove 11 on the lower surface of described draw-bar box body 1, described should auxiliary castor groove 11 be to be used to place auxiliary castor 32, and the lower end of supplemental support panel 31 is connected with auxiliary castor 32.
When not needing to assist the castor co-operation, only need enforce supplemental support panel 31, promptly because under the elastic force effect of the elastomeric element 33 in the rear-mounted auxiliary caster device 3, auxiliary castor 32 just shrinks in the auxiliary castor groove 11 that is hidden in draw-bar box body 1 back;
When firmly pushing elastomeric element 33, elastic force effect by the elastomeric element 33 in the rear-mounted auxiliary caster device 3, auxiliary castor 32 is stretched out from auxiliary castor groove 11 interior elasticity with supplemental support panel 31, and be automatically brought to and main castor parallel arranged, constitute double castor and roll; In addition because from assisting the rear-mounted auxiliary caster device 3 of stretching out in the castor groove 11 to constitute the triangle force structure with draw-bar box body 1, overcome the weight component that casing tilts to produce fully, drag this moment or only need overcome friction when carrying out casing, thereby when promoting the draw-bar box of the utility model structure, reached the labour-saving purpose; Can be easily will assist castor to be contracted in the auxiliary castor groove 11 after rear-mounted auxiliary caster device 3 is finished using stretching out, and make draw-bar box return to main castor tension state when working independently again.
By will assist castor 32 to be contracted in the auxiliary castor groove 11 of draw-bar box body 1 lower end hidingly, therefore, auxiliary castor 32 does not take redundant space, does not influence the placement of suitcase;
When dragging the utility model draw-bar box, rear-mounted auxiliary caster device 3 is stretched out and is opened, and drags chest gravity thereby alleviated people greatly.
