Detailed Implementation

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] Example

[0021] Please see Figures 1-6 This utility model discloses a foldable concealed pull rod for a suitcase, comprising a pull rod connecting frame 1, two sets of U-shaped groove rods 5, and two sets of extension rods 10. Mounting holes 2 are provided at both corners of the pull rod connecting frame 1. Two sets of storage square tubes 3 are symmetrically fixedly connected to the back of the pull rod connecting frame 1. A clearance groove 4 is provided at one end of the inner side of each of the two sets of storage square tubes 3 near the back of the pull rod connecting frame 1. Limiting posts 6 are fixedly connected to the lower inner wall of the rear end of each of the two sets of U-shaped groove rods 5. Two sets of limiting posts are symmetrically provided on the front of the pull rod connecting frame 1. The groove 7, two sets of U-shaped groove rods 5 are slidably installed in the two sets of storage square tubes 3 through the cooperation of the limiting post 6 and the limiting groove 7. A first handle 8 is fixedly connected between the inner top of the two sets of U-shaped groove rods 5, and a second handle 9 is fixedly connected between the inner top of the two sets of extension rods 10, with the rear end of the second handle 9 aligned with the rear end of the extension rod 10. A rotating shaft 11 is fixedly connected to the lower side of both ends of the two sets of extension rods 10. A connecting hole is opened through the upper side of both sets of U-shaped groove rods 5, and the two sets of extension rods 10 are connected by the rotating shaft. The extension rod 10 is rotatably mounted on two sets of U-shaped groove rods 5, with an interference fit between the left and right ends of the extension rod 10 and the inner walls of the U-shaped groove rods 5. Positioning grooves 12 are provided on the lower inner sides of both sets of U-shaped groove rods 5 to mate with the second handle 9, and the thickness of the second handle 9 is the same as the width of the clearance groove 4. In use, by retracting the U-shaped groove rods 5 and the extension rod 10, the pull rod is at its shortest length, and the first handle 8 is exposed. The suitcase can be moved by pushing it through the first handle 8. For people of average height, the U-shaped groove rod 5 can be fully extended, and the suitcase can be pulled by the first handle 8. For taller people, after fully extending the U-shaped groove rod 5, the extension rod 10 can be rotated out from the U-shaped groove rod 5, keeping the extension rod 10 vertical with the U-shaped groove rod 5. At this point, the pull rod is at its longest length, and the suitcase can be pulled by the second handle 9. This allows the pull rod length to be suitable for people of different heights, ensuring convenient movement of the suitcase and improving practicality.

[0022] The pull rod connecting frame 1 has fastening rubber pads 13 fixedly connected to both the left and right sides of its back; by setting the fastening rubber pads 13, the pull rod connecting frame 1 can be more tightly and securely installed with the suitcase.

[0023] The second handle 9 has four sets of finger grooves 14 equidistantly spaced at the end facing the first handle 8. By setting the finger grooves 14, when the suitcase is pulled by the second handle 9, the four fingers other than the thumb can be placed in the four sets of finger grooves 14 respectively, thereby effectively preventing the hand from slipping on the second handle 9.

[0024] The surface of the first handle 8 is provided with anti-slip mesh 15; by providing anti-slip mesh 15, the surface friction of the first handle 8 can be increased, making it less likely for the hand to slip when pulling the suitcase with the first handle 8.

[0025] This utility model discloses a folding concealed pull rod for suitcases. In use, the pull rod connecting bracket 1 is fixed to the upper middle position on the back of the suitcase via screws and mounting holes 2. When the U-shaped groove rod 5 and extension rod 10 are retracted, the pull rod is at its shortest length, and the first handle 8 is exposed. For people of average height, the suitcase can be moved by pushing it with the first handle 8, or the U-shaped groove rod 5 can be fully extended and pulled by the first handle 8. The limiting post 6 and the limiting groove 7 prevent the U-shaped groove rod 5 from detaching from the storage square tube 3. The interference fit between the extension rod 10 and the U-shaped groove rod 5, and the locking of the second handle 9 and the positioning groove 12, prevent the extension rod 10 from rotating out of the U-shaped groove rod 5 after it is extended. This design is suitable for taller individuals. It is said that after the U-shaped groove rod 5 is fully extended, the extension rod 10 can be rotated out of the U-shaped groove rod 5 through the second handle 9, so that the extension rod 10 and the U-shaped groove rod 5 are vertical. At this time, the pull rod is at its longest length, and the suitcase can be moved by pulling it through the second handle 9. When the extension rod 10 is rotated out and is vertical to the U-shaped groove rod 5, the extension rod 10 abuts against the inner wall of the rear side of the U-shaped groove rod 5, which plays a role in bearing the weight. When storing, simply rotate the extension rod 10 counterclockwise to insert the second handle 9 into the positioning groove 12, and the extension rod 10 can be hidden in the U-shaped groove rod 5. At this time, the second handle 9 is aligned with the clearance groove 4. Then, push the U-shaped groove rod 5 downward through the first handle 8, so that the U-shaped groove rod 5, the second handle 9 and the extension rod 10 are hidden together in the storage square tube 3, leaving only the first handle 8 on the outside, and the hiding and storage is completed.

[0026] The present invention relates to a folding concealed pull rod for suitcases. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
