A control bar is disposed between two top ends of the two support columns, and the connection mount is mounted between two bottom ends of the two support columns and includes two locking recesses defined on one side thereof. Each retainer has an abutting face and two contacting faces, wherein each contacting face has an engaging rib arranged thereon to retain with each of the two locking recesses. Thereby, the at least two retainers are connected with the connection mount of the trolley, and each retainer has the abutting face, such that the at least two retainers position columnar or cylindrical goods stably as pushing the trolley, thus avoiding the goods dropping from the trolley.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a trolley, and more particularly to a goods fixing structure for the trolley.

2. Description of the Prior Art

A conventional trolley contains a support frame, at least one roller disposed on two sides of a bottom end of the support frame, and a holding plate mounted on the bottom end of the support frame to hold goods, wherein an angle between the holding plate and the support frame is 90 degrees, such that the goods are placed on the holding plate and contact with the support frame so that the trolley is pushed to move by using its at least one roller. However, the goods cannot be fixed by a fixing structure of the trolley as moving the trolley. For example, as carrying cylindrical goods by using the trolley, the cylindrical goods vibrate or drop from the trolley easily.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a goods fixing structure for a trolley in which two retainers are connected with a connection mount of the trolley, and each retainer has an abutting face, such that the two retainers position columnar or cylindrical goods stably as pushing the trolley, thus avoiding the goods dropping from the trolley.

Another objective of the present invention is to provide a goods fixing structure for a trolley in which each retainer has two contacting faces, and lengths of the two connecting faces are different, such that the two retainers are connected with the trolley by using the two contacting faces of each retainer to change a distance between the two retainers, hence the goods of different sizes are carried by the trolley easily.

To obtain above-mentioned objectives, a goods fixing structure for a trolley provided by the present invention contains: two support columns, a connection mount, and at least two retainers.

A control bar is disposed between two top ends of the two support columns, and the connection mount is mounted between two bottom ends of the two support columns and includes two locking recesses defined on one side thereof.

Each retainer has an abutting face and two contacting faces, wherein each contacting face has an engaging rib arranged thereon to retain with each of the two locking recesses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIGS. 1 and 2, a goods fixing structure for a trolley 10 according to a preferred embodiment of the present invention comprises: two support columns 11, a connection mount 13, and at least two retainers 20.

A control bar 12 is disposed between two top ends of the two support columns 11.

The connection mount 13 is mounted between two bottom ends of the two support columns 11 and includes two locking recesses 131 defined on one side thereof, and a connector 14 is fixed between two middle sections of the two support columns 11, wherein the connector 14 includes at least one pair of retaining slots 141 formed on one side surface thereof. The connection mount 13 also includes the at least two retainers 20 retained thereon, wherein each retainer 20 has an abutting face 21 and two contacting faces 22 and is formed in a right triangle block shape, the abutting face 21 is an arcuate surface, and the two contacting faces 22 are perpendicular to each other, wherein a length of one of the two contacting faces 22 is more than the other of the two contacting faces 22, the abutting face 21 faces to a vertical connecting corner of the two contacting faces 22, and each contacting face 22 has an engaging rib 221 arranged thereon, such that each retainer 20 is connected with the connection mount 13 or the connector 14 by ways of the engaging rib 221 of each contacting face 22, thus assembling the goods fixing structure completely.

In operation, as shown in FIGS. 1, 3 and 4, the engaging rib 221 of each contacting face 22 of each retainer 20 retains with each of the two locking recesses 131 of the connection mount 13, and two abutting faces 21 of the two retainers 20 face to each other, such that an arcuate limiting space is defined between the two retainers 20 to contact with outer walls of columnar or cylindrical goods, and the two retainers 20 position the columnar or cylindrical goods securely to avoid the goods dropping from the trolley 10.

Since the length of one of the two contacting faces 22 is more than the other of the two contacting faces 22, the two retainers 20 are changeably connected with the connection mount 13 or the connector 14 based on sizes of the goods, as illustrated in FIGS. 5 and 6, when one of the goods with a larger diameter is placed onto the trolley 10, one of the two contacting faces 22 with a longer length is connected with the connection mount 13 to increase a distance between the two retainers 20, hence a contact area of the two abutting faces 21 is widen to carry one of the goods with the larger diameter. when another of the goods with a smaller diameter is placed onto the trolley 10, the other of the two contacting faces 22 with a shorter length is connected with the connection mount 13 to decrease the distance between the two retainers 20, hence the contact area of the two abutting faces 21 is reduced to carry another of the goods with the smaller diameter. Thereby, the trolley 10 carries different goods securely and easily.

The goods fixing structure of the present invention contains benefits as follows:

1. The two retainers 20 are connected with the connection mount 13 of the trolley 10, and each retainer 20 has the abutting face 21, such that the two retainers 20 position the columnar or cylindrical goods stably as pushing the trolley 10, thus avoiding the goods dropping from the trolley 10.

2. Each retainer 20 has the two contacting faces 22, and lengths of the two connecting faces 22 are different, such that the two retainers 20 are connected with the trolley 10 by using the two contacting faces 22 of each retainer 20 to change the distance between the two retainers 20, hence the goods of different sizes are carried by the trolley 10 easily.

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
