In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a luggage support frame, which has the advantages of meeting the light weight requirements of customers and greatly reducing the production cost.

The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: a luggage support frame, comprising a plurality of connecting rods and a plurality of bending parts, and the two ends of the bending parts are respectively provided with sockets inserted into the connecting rods. The connecting rod is hollow, the cross section of the connecting rod is non-circular, and the inner wall of the connecting rod is provided with reinforcing ribs.

Preferably, the non-circular configuration is D-shaped, and the cross-section of the reinforcing rib is extended along the horizontal inner wall toward the arcuate inner wall.

Preferably, the non-circular arrangement is rectangular, and the cross-section of the reinforcing rib is arranged crosswise along the diagonal of the rectangle.

Preferably, both the connecting rod and the bending portion are made of plastic.

Preferably, the bending portion includes a guide groove provided with a guide hole and a connecting portion connecting two guide grooves, the connecting portion is respectively connected with the guide grooves at both ends of the curved surface transition, and the two guide grooves are connected to the two guide grooves. A connecting rib is arranged between the connecting parts, and the connecting rib is arranged along the connecting part and the edge of the outer wall of the guide groove.

To sum up, the utility model has the following beneficial effects: the utility model provides a luggage support frame, the luggage support frame is provided with a plurality of connecting rods and a plurality of bending parts for the connecting rods to be surrounded into a rectangle, which can be used as a A skeleton for supporting luggage, and the cross-section of the connecting rod is non-circular. When the connecting rod is plugged and fitted with both ends of the bending portion, the connecting rod can make the connection between the bending portion and the plug-fitted connection therewith. The rods will not slide relative to each other, thus forming a stable connection structure, which is not easy to be separated. In addition, the connecting rods are hollow and are provided with reinforcing ribs on the inner wall. This makes it possible to further strengthen the toughness of the connecting rod while reducing the production cost and the weight of the support frame.

Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

It should be noted that when a component is referred to as being "fixed to" or "disposed to" another component, it can be directly on the other component or indirectly on the other component. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that A device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as a limitation of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only, and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature defined as "first", "second" may expressly or implicitly include one or more of that feature. In the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

A luggage support frame, referring to FIG. 1 and FIG. 2, includes a plurality of connecting rods 1 and a plurality of bending parts 2, and the two ends of the bending parts 2 are respectively provided with guide holes for plugging and matching with the connecting rods 1 , the connecting rod 1 is hollow, the cross-section of the connecting rod 1 is non-circular, and the inner wall of the connecting rod 1 is provided with a reinforcing rib 4 .

The utility model provides a luggage support frame. The luggage support frame is provided with a plurality of connecting rods 1 and a plurality of bending parts 2 for connecting the plurality of connecting rods 1 to each other, so as to be used as a skeleton for supporting the luggage, and the connection The cross-section of the rod 1 is a non-circular configuration 3. When the connecting rod 1 is inserted and matched with the two ends of the bending portion 2, the bending portion 2 and the connecting rod 1 that is plugged and matched with it can not be inserted. Relative sliding occurs, thereby forming a stable connection structure, and it is not easy to separate from the situation. In addition, the connecting rod 1 is hollow and the inner wall is provided with reinforcing ribs 4. Through the hollow setting, the production cost of raw materials is reduced, and the function of the reinforcing ribs 4 This makes it possible to further strengthen the toughness of the connecting rod 1 while reducing the production cost and the weight of the support frame.

Specifically: the non-circular arrangement 3 is D-shaped, and the cross-section of the reinforcing rib 4 is extended along the horizontal inner wall toward the arc-shaped inner wall.
