Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.

The multi-functional convenient trolley that gathers together that shows as fig. 1-3, including four gyro wheel main part 1, the equal fixedly connected with bracing piece 2 of up end of four gyro wheel main part 1, the equal fixedly connected with third connecting block 11 of up end of four bracing piece 2, the equal sliding connection in surface of four bracing piece 2 has fourth connecting block 8, still includes:

the folding supporting mechanism is positioned among the four supporting rods 2 and used for supporting goods in the vehicle body;

at least ten outer rod mechanisms, ten outer rod mechanisms and four fourth connecting blocks 8 are hinged in a head-to-tail rotation mode to form a rectangle, each outer rod mechanism comprises a first straight rod 9 and two second arc plates 13, and the two second arc plates 13 are fixedly connected to two ends of the first straight rod 9 respectively;

at least ten interior pole mechanisms, ten interior pole mechanisms and four third connecting blocks 11 head and the tail rotate articulated rectangle that is, every interior pole mechanism all includes second straight-bar 10 and two first arc 12, and two first arc 12 are fixed connection respectively in the both ends of second straight-bar 10, and ten second straight-bar 10 rotate respectively and articulate on ten first straight-bars 9, and ten second straight-bar 10 all are located the inboard of ten first straight-bars 9.

When the folding support mechanism is required to be folded, the folding support mechanism is pulled upwards, so that the four support rods 2 are driven to move to the side close to each other, the four support rods 2 are driven to rotate the second straight rods 10 and the first straight rods 9, because the ten second straight rods 10 are located on the inner sides of the ten first straight rods 9, the ten second straight rods 10 and the ten first straight rods 9 can not interfere with each other alternately when rotating, meanwhile, the two ends of the first straight rods 9 are provided with the arc-shaped second arc-shaped plates 13, the two ends of the second straight rods 10 are provided with the arc-shaped first arc-shaped plates 12, and therefore two adjacent first straight rods 9 or two adjacent second straight rods 10 can rotate to be in a complete contact fit, and accordingly the two adjacent first straight rods 9 or two adjacent second straight rods 10 are in a parallel state.

Specifically, folding supporting mechanism includes four first bull stick 3, and four first bull sticks 3 rotate respectively and articulate on four bracing pieces 2, and the other end of two first bull sticks 3 in left side and two first bull sticks 3 in right side all rotates and articulates there is first connecting block 4, all rotates on two first connecting blocks 4 and articulates there are two second bull sticks 5, all rotates on two second straight-bars 10 in middle part and articulates there is traction lever 7, and the equal fixedly connected with second connecting block 6 of lower terminal surface of two traction levers 7, and four second bull sticks 5 rotate respectively and articulate on two second connecting blocks 6.

During operation, when this device is accomodate to needs, hold two first connecting blocks 4, upwards pull two first connecting blocks 4, two first connecting blocks 4 drive first dwang 3 and the rotatory being close to of second bull stick 5, thereby realize that one side that four bracing pieces 2 are close to moves mutually, because the one end of four first dwang 3 is taken on four gyro wheel main bodies 1, and the one end of four second bull sticks 5 is pulled through two traction bars 7 that do not lengthen, be equipped with the baffle on the second connecting block 6 simultaneously and make first connecting block 4 can not rotate downwards on second connecting block 6, consequently spread the canvas on this device can bear the weight of the goods on the canvas and can not cause the goods to drop.

Specifically, the two support rods 2 on the right side are fixedly connected with connecting plates 14, one end faces, close to the two connecting plates 14, of the two connecting plates are rotatably hinged with rotating plates 15, and an I-shaped handle 16 is rotatably hinged between the two rotating plates 15.

When the device is required to be stored, the two support rods 2 on the right side move to the side close to each other, the I-shaped handle 16 moves upwards or downwards to drive the two rotating plates 15 to rotate, so that the storage of the device is not affected, and the I-shaped handle 16 can be pulled to drive the device to move on the ground after the device is opened.

The working principle of the utility model is as follows:

when this device is drawn in to needs, upwards pulling folding supporting mechanism to drive four bracing pieces 2 to the one side that is close to remove, four bracing pieces 2 remove and drive second straight-bar 10 and first straight-bar 9 rotation, because ten second straight-bars 10 all are located ten first straight-bar 9 inboards, can not interfere each other in turn when ten second straight-bars 10 and ten first straight-bars 9 rotate, simultaneously because the both ends of first straight-bar 9 are provided with curved second arc 13, the both ends of second straight-bar 10 are provided with curved first arc 12, consequently two adjacent first straight-bars 9 or two second straight-bars 10 can rotate to the laminating of full contact, thereby realize that two adjacent first straight-bars 9 or two second straight-bars 10 are parallel state.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the foregoing embodiments, but rather, the foregoing embodiments and description illustrate the principles of the utility model, and that various changes and modifications may be effected therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
