Through above-mentioned technical scheme, the buffer ring cover is located the first buffer spring outside, avoids user's hand directly to contact with first buffer spring.

Preferably, the handle device further comprises a second buffer spring, the second buffer spring is connected to the end of the contact ring, which faces away from the moving handle, and the end of the second buffer spring, which faces away from the contact ring, can be in contact with the buffer ring.

Through above-mentioned technical scheme, when the telescopic link slided toward the box inside, after first buffer spring pressurized to certain length, the buffering ring can contact with second buffer spring, and second buffer spring can produce secondary buffering effect to the buffering ring, has further promoted whole buffering effect.

Preferably, the elastic coefficient of the second buffer spring is greater than the elastic coefficient of the first buffer spring.

Through above-mentioned technical scheme, second buffer spring's buffer power is bigger, can stop the removal of telescopic link sooner.

Preferably, the end of the contact ring is connected with the moving handle through a threaded connection.

Through the technical scheme, firstly, the contact ring and the movable handle are convenient to disassemble and assemble; secondly, also can adjust the distance between the tip that the contact ring deviates from the removal handle and the removal handle, its essence is the adjustment and is located the second buffer spring of the tip that the contact ring deviates from the removal handle and the interval size between the buffer ring, finally adjusts the buffer distance of second time.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

A traveling case, see figure 1, comprises a case body 1 and a pull rod structure. The pull rod structure is arranged at the upper position of the box body 1.

Referring to fig. 2, the pull rod structure includes a moving handle 2 and more than two telescopic rods 3, the number of the telescopic rods 3 shown in this embodiment is two, and the moving handle 2 is connected to the end positions of two adjacent telescopic rods 3. The telescopic rod 3 is vertically arranged as a whole.

Referring to fig. 2 and 3, a buffer ring 4 is slidably sleeved on each telescopic rod 3, and the buffer ring 4 is preferably in a ring shape.

Referring to fig. 3 and 4, the cushion ring 4 can slide vertically along the extension and contraction direction of the telescopic rod 3. A first buffer spring 5 is connected between the buffer ring 4 and the moving handle 2. The side wall of the buffer ring 4 departing from the moving handle 2 is provided with a rubber pad 6, and the rubber pad 6 can be abutted against the outer side wall of the box body 1.

Referring to fig. 4, a rolling element 7 is rotatably connected to an inner circumferential surface of the cushion ring 4, and the rolling element 7 is a ball. The outer rod surface of the telescopic rod 3 is provided with a sliding groove 8, the length direction of the sliding groove 8 is consistent with that of the telescopic rod 3, and the rolling body 7 is connected in the sliding groove 8 in a rolling and sliding manner.

Referring to fig. 4, each telescopic rod 3 is further sleeved with a contact ring 9, the contact ring 9 is annular, and the outer diameter of the buffer ring 4 is preferably larger than that of the contact ring 9. The end of the contact ring 9 is connected to the moving handle 2 by means of a screw connection. The contact ring 9 is located between the buffer ring 4 and the moving handle 2, one end of the contact ring 9 is connected to the moving handle 2, and the first buffer spring 5 is located in the contact ring 9.

Referring to fig. 4, a second buffer spring 10 is further included, the second buffer spring 10 being connected to the end of the contact ring 9 facing away from the moving handle 2, the end of the second buffer spring 10 facing away from the contact ring 9 being contactable with the buffer ring 4.

Wherein, the elastic coefficient of the second buffer spring 10 is larger than that of the first buffer spring 5.

In the in-service use, when needs slide 3 to the box in 1 with the telescopic link, the handheld removal handle 2 of user and promotion telescopic link 3 move to the box in 1, the rubber pad 6 of buffer ring 4 can earlier contact with 1 lateral wall of box, buffer ring 4 compresses first buffer spring 5 earlier, after first buffer spring 5 compressed the certain degree, buffer ring 4 can contact with second buffer spring 10, realize the double cushioning effect.
