Detailed Implementation

[0023] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0024] A type of folding concealed pull rod for a suitcase, such as Figures 1-6 As shown, the luggage includes a suitcase body 1, a handle 2, a pull rod 4, a guide rail 5, and a set of limiting blocks 51. The suitcase body 1 is provided with a guide rail 5, and a pull rod 4 is slidably connected to the guide rail 5. The handle 2 is fixedly connected to the top of the pull rod 4. The handle 2 is provided with a pressing and lifting mechanism. The bottom of the pressing and lifting mechanism is provided with a segmenting mechanism. The left and right side walls inside the guide rail 5 are provided with a set of limiting blocks 51 distributed vertically. The gap between the set of limiting blocks 51 forms a limiting groove. A traction groove 17 is opened on the front side of the handle 2. An inlet groove 16 corresponding to the position of the traction groove 17 is opened on the front side of the receiving groove 18 to guide the user's fingers to position and pull out the handle 2 smoothly.

[0025] like Figure 4 As shown, the pressing and lifting mechanism includes a pressing block 6, a first compression spring 7, a bearing seat 8, a movable plate 9, and a connecting rod 10. The first compression spring 7 is located on the inner side of the bottom of the handle 2, and the pressing block 6 is located on the top of the first compression spring 7. The pressing block 6 passes through the top of the handle 2. The bearing seat 8 is located inside the rear side of the handle 2. The movable plate 9 is rotatably connected to the outer side of the bearing seat 8. A torque spring is connected between the bearing seat 8 and the movable plate 9. The torque spring is made of stainless steel to ensure reliable reset performance during long-term use. The end of the movable plate 9 near the pressing block 6 is located below the pressing block 6. The outer side of the movable plate 9 away from the pressing block 6 is hinged to the connecting rod 10. The bottom of the connecting rod 10 is provided with a segmenting mechanism.

[0026] like Figure 5 As shown, the segmentation mechanism includes an inclined block 11, a movable block 12, and a second compression spring 13. The bottom of the connecting rod 10 is provided with an inclined block 11, and the lower part of the pull rod 4 has rectangular holes on both sides. The movable block 12 is slidably connected in the rectangular holes. The inner wall of the rectangular holes is provided with guide strips to guide and limit the sliding of the movable block 12. The top of the movable block 12 is designed as an inclined surface. The inclined block 11 can squeeze the inclined surface to make the movable block 12 move to the left and right sides. The second compression spring 13 is connected between the two movable blocks 12.

[0027] like Figure 6As shown, it also includes a metal sheet 14 and a magnetic sheet 15.

[0029] In use, the user presses down on the pressing block 6, which moves downward to push the movable plate 9 to rotate around the shaft seat 8, thereby driving the connecting rod 10 to move upward. The connecting rod 10 drives the inclined block 11 to move upward, thus moving it away from the moving block 12. Under the action of the second compression spring 13, the two moving blocks 12 move closer to each other, thus moving away from the limit block and releasing the locked state. The user can pull the lever 4 to a suitable length according to different heights or usage needs. During the upward movement of the lever 4, whenever the moving block 12 reaches a certain limit block group... At position 51, magnetic tactile feedback is generated between magnetic sheet 15 and metal sheet 14, indicating to the user that the current position is in a valid locking position. At this time, the pressing block 6 is released, the first compression spring 7 pushes the pressing block 6 to rebound, and under the restoring force of the torque spring, the movable plate 9 is driven back to the horizontal state, thereby driving the connecting rod 10 to move downward, so as to drive the inclined block 11 to move downward. The inclined block 11 presses the inclined surface of the moving block 12 to make the two moving blocks 12 move away from each other and lock into the limiting groove between the limiting block group 51, thus completing the fixing of the pull rod 4.
