Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 3, in embodiment 1 of the present invention, a foldable cart includes a front baffle 2, a rear baffle 10, a base 16, a folding mechanism 8, a universal wheel 15, a control rod 21, a front support column 1, a rear support column 14, a limit rod 12, and a hinge rod 5; the two sides of the front baffle 2 are respectively connected with the rear baffle 10 through folding mechanisms 8, each folding mechanism 8 comprises a control rod 21, one side of each control rod 21 is fixedly connected with a row of uniformly arranged axle center columns 7, the upper sides of the axle center columns 7 are respectively hinged with hinged rods 5, and the two sides of the axle center column 7 at the bottom of each control rod 21 are respectively hinged with a base 16; the inboard gag lever post 12 that articulates that has of axle center post 7 below control lever 21, gag lever post 12 top rigid coupling has the couple 13 of the style of calligraphy of falling U.

This handcart is flat completely to folding mechanism 8 when using, provides the support for preceding baffle 2 and backplate 10 of both sides through gag lever post 12, avoids folding mechanism 8 to appear folding, makes the handcart remain stable, needs foldingly through removing gag lever post 12, can change the interval between preceding baffle 2 and the backplate 10, accomplishes foldingly.

Example 2

Referring to fig. 1 to 3, the main differences between the embodiment 2 and the embodiment 1 are:

preceding baffle 2 includes the preceding support column 1 of both sides, the rigid coupling has multiunit horizontal pole 9 between two preceding support columns 1 of preceding baffle 2, the rigid coupling has the montant of connecting horizontal pole 9 on the

horizontal pole

9, 1 bottom rigid couplings of preceding support column have universal wheel 15. The side rigid coupling of preceding support column 1 has multiunit evenly distributed's articulated seat 4, articulated seat 4 is articulated with the rod end of hinge bar 5, the inboard rigid coupling of preceding support column 1 has spacing post 3 of the parallel horizontal pole 9 of multiunit, spacing post 3 becomes to be and erects the range align to grid. The backplate 10 includes back support columns 14 of both sides, the rigid coupling has multiunit horizontal pole 9 between two back support columns 14 of backplate 10, the rigid coupling has the montant of connecting horizontal pole 9 on the horizontal pole 9, back support column 14 bottom rigid coupling has universal wheel 15, back support column 14 top rigid coupling has handle 11. The side rigid coupling of back support column 14 has multiunit evenly distributed's articulated seat 4, articulated seat 4 is articulated with the rod end of hinge bar 5, the inboard rigid coupling of back support column 14 has the spacing post 3 of the parallel horizontal pole 9 of multiunit, spacing post 3 becomes to be the vertical row align to grid. Base 16 one side is articulated with articulated seat 4, base 16 opposite side rigid coupling has the articulated joint 17 of multiunit downward sloping, be equipped with notch 20 between the articulated joint 17, it is adjacent open on the articulated joint 17 has through-hole 18, articulated seat 4 is articulated with adjacent base 16 through the locating lever 19 that passes through-hole 18, and the articulated joint 17 of two adjacent bases 16 inserts in the notch 20 of the base 16 of the other side. The top of the control rod 21 is fixedly connected with a pull ring 6.

Put down the control lever 21 among the folding mechanism 8 during the use, make all hinge rod 5 all keep the level, the couple 13 on gag lever post 12 top this moment just can be hung on horizontal position's spacing post 3, props up spacing post 3 through gag lever post 12, avoids preceding baffle 2 and backplate 10 to be close to each other, can make the handcart remain stable, can not appear warping at the in-process of holding and transporting goods.

Folding when accomodating at needs handcart, take off couple 13, upwards stimulate pull ring 6, make the 5 parallel rotations of all hinge bar of control lever 21 control, baffle 2 and backplate 10 constantly are close to the state of compressing tightly before this in-process, move gag lever post 12 to topmost this moment, hang couple 13 on the spacing post 3 of the top, spacing post 3 is strained to gag lever post 12, make the preceding baffle 2 of both sides and backplate 10 can not break away from control lever 21, remain throughout and press from both sides tight state, the structure is more stable, loose can not appear.

When the handcart worked in narrower and small environment, or the goods volume of transportation was less, can improve the take the altitude with control lever 21, couple 13 on the gag lever post 12 is hung on a higher spacing post 3, can carry out the folding of certain degree to this small handcart, incompletely realize folding simultaneously, and the distance of preceding baffle 2 and backplate 10 is subject to the support of gag lever post 12 under this kind of state, can not change, consequently, this small handcart still can be used for the transportation under this kind of state, it is very nimble convenient to use.

The utility model discloses a theory of operation is:

folding mechanism 8 of this first shallow has articulated rod 5 that the multiunit is parallel, it constitutes with control lever 21 that both sides all are connected with multiunit articulated rod 5, can adjust 5 section of thick bamboo angular displacements of all articulated rods through the removal of control lever 21, and can utilize the effect of gag lever post 12 to realize fixed of angle after the removal, baffle 10 interval reduces around stopping through gag lever post 12 when the small handcart uses, can prevent to take place folding preceding baffle 2 and backplate 10 separation through gag lever post 12 after folding, when needs half folding state reduce the volume and transport simultaneously, also can be through the effect of gag lever post 12, make the small handcart whole remain stable under half folding state, make the use of this small handcart more nimble changeable, accommodation is wider.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
