Detailed Description
The utility model will be further described with reference to examples and drawings.
In a first embodiment, as shown in fig. 1-2, a frame jacking of a cloth case is formed by integrally injection molding a plastic material, and includes a top plate 1, a front bending portion 2 and a rear bending portion 3, wherein the top plate 1 and the front bending portion 2, the top plate 1 and the rear bending portion 3 are smoothly transited, and a pull rod mounting position 5 is formed on the rear bending portion 3. The frame jacking in the first embodiment has better rigidity and toughness than an extrusion plate due to the adoption of integral injection molding, and can play a better supporting role on the cloth shell, so that the frame of the luggage is more stable, and the appearance is smoother and more attractive; the pull rod can be directly arranged at the pull rod installation position 5 of the frame jacking, other installation structures can be simplified, and therefore the whole ultralight design of the luggage can be realized.
In the first embodiment, as shown in fig. 1 and 2, a plurality of reinforcing ribs 6 are disposed on the inner sides of the top plate 1, the front bending portion 2 and the rear bending portion 3. The structure can increase the overall rigidity and toughness of the frame jacking, ensure no deformation and play a better supporting role on the cloth shell of the luggage.
In the first embodiment, as shown in fig. 1 and 2, a first hollow portion 4 is provided on the top plate 1, and a hollow portion 7 is provided on the front bending portion 2. The hollow design does not influence the overall strength of the product, but can lighten the weight, and meets the requirement of ultra-light design on the premise of ensuring the strength and hardness requirements.
In the first embodiment, as shown in fig. 1 and 2, extension portions 8 are provided at both ends of the front edge of the front bending portion 2. The extension part 8 can play an extension supporting role on the cloth shell of the case, so that the whole appearance of the case is smoother and more attractive.
