Description

Folding utility transport trolley

Technical field

The utility model belongs to vehicle arts field, is specifically related to a kind of folding utility transport trolley.

Background technology

Nowadays, transport trolley has been popularized in places such as hypermarket and birds and flowers markets, and no matter at supermarket shopping, or carrying flowers, weight, chemical products etc. all need to use transport trolley.But the most function singleness of these transpories trolley, substantially be all made up of hoop, wheel and hand handle, its deficiency existed mainly contain following some: 1. hoop adopts stainless (steel) wire lattice structure, and chemical products can produce corrosion when rehandling, and is difficult to cleaning because pulling down; 2. can only transporting general goods, very bothering when transporting big article, especially when carrying the article such as flowers, traditional hoop frame is too high, easily destroys the branches and leaves that flowers hang; 3. general transport trolley only has a hoop, shipping goods limited amount, cannot meet the needs of customer; 4. the wheel that transport trolley generally uses is roller, lightweight, and road surface adaptive capacity is poor and easily shake, and is unfavorable for the transport of dangerous material and precious article.

In prior art, disclosed in Chinese utility model patent Authorization Notice No. CN201405897Y a kind of " there is the supermarket shopping car of the double holding thing string bag ", comprise body framework, wheel, the lower dress thing string bag of a bottom framework and montant frame composition, also include on one and fill the thing string bag, montant frame is mainly made up of the symmetrical montant in four, left and right and two upper and lower lateral pull fixed links, a support fixed link and a horizontal pushing hands bar, and the upper dress thing string bag to be arranged on montant frame and collapsible.This shopping cart has had very large improvement than Traditional Transportation car, but still there is many deficiencies: first, and the upper and lower string bag is non-dismountable formula structure, adds the difficulty of cleaning; Secondly, the upper dress thing string bag and montant frame are overturn by rectangle frame and are connected, and Joint strenght is inadequate between the two, and rectangle frame easily ruptures and affects service life; 3rd, the upper dress thing string bag is lifted without base, is directly set up on montant frame, easily makes the dress thing string bag produce deformation and cause folding.

Again for example, the one " flowers transport vehicle " that Chinese utility model patent Authorization Notice No. CN2883240Y introduces, comprises a base plate and at least three blocks of side plates, it is characterized in that, described base plate is connected with a piece in three blocks of side plates by pivot, and described base plate can pivot.The side plate be connected with described base plate is connected with at least one piece in another two blocks of side plates rotationally by pivot again.Because the utility model is by between base plate and side plate, with setting makes relatively turnable pivot between the two between side plate and side plate, whole transport trolley can be enable to fold up, take quite little volume, like this after having sent flowers and trees, relatively less traffic cost can be utilized to be transported back by this transport trolley, reach and recycle and cost-saving object.The shortcoming of this transport trolley is: its structural strength is poor, the limited space of placement flowers and trees, is not suitable for transporting larger potted flowers; Wheel is light, is difficult to carry out under Uneven road situation, cannot meet the user demand that customer is daily.

In view of above-mentioned prior art, be necessary to be improved the structure of existing transport trolley.For this reason, the applicant has done actively actv. exploration, finally defines technical scheme described below.
