Description

A kind of convertible tablet trolley and its fixed device

Technical field

The utility model relates to a kind of trolley more particularly to a kind of convertible tablet trolley and its fixed devices.

Background technique

Trolley is the handbarrow for being pushed away, being drawn with manpower, is continued to develop although material carries technology, trolley still conduct Indispensable handbarrow and use till today.It is because of its low cost that trolley obtains extensive use in production and life Honest and clean, maintenance is simple and convenient to operate, from heavy and light, can be in the local work that motor vehicles inconvenience uses, and short-haul operation article is very It is convenient.

Flat trolley is the biggish a kind of trolley of load-bearing capacity, but is not used widely in the public, Tracing it to its cause mainly has two o'clock: because flat trolley does not have folding property, or being only simply to rotate handle on the one hand It fits on bottom plate, causes the occupied area of flat trolley larger, for general family, difficulty has enough spaces to deposit It is laid flat board-like trolley；On the other hand, personal for daily small-sized buying, it can the small shopping cart of the flexible rod-pulling type of selection transportation It can meet, and need to carry heavier cargo or the more cargo machine of a number of packages can be fewer, so, general family is not It is ready specially to buy flat trolley thus.

Therefore, it for disadvantages described above, needs effectively to innovate existing flat trolley.

Utility model content

The purpose of this utility model is to provide a kind of convertible tablet trolleys and its fixed device, this kind of trolley to adopt With sharing mode, the use cost of trolley is on the one hand reduced, on the other hand more other trolleys have better load-bearing energy Rotational structure is arranged in power on trolley, improves the folding degree of trolley, in addition, using fixed device to trolley into Row is fixed, and trolley is placed in shared region, further reduced the space occupancy rate of trolley, while facilitating the public Also economic benefit can be obtained.

To achieve the above objectives, the present invention adopts the following technical solutions:
