DETAILED DESCRIPTION

[0022] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0023] Reference Figure 1The present embodiment provides a trolley case with a trolley fixing structure, including a case body 1 and a trolley assembly 2. A receiving groove 11 for receiving the trolley assembly 2 is provided on the side of the case body 1. The lower end of the trolley assembly 2 is hinged to the case body 1, and a conventional hinge structure is adopted, which is not shown in detail.

[0024] Reference Figure 2 A mounting seat 3 is fixedly provided on the pull rod assembly 2. Specifically, sleeve holes 36 are provided on both sides of the mounting seat 3, and then the mounting seat 3 is tightly sleeved on the rod body of the pull rod assembly 2 through the sleeve holes 36.

[0025] A sliding groove 35 is provided on the mounting seat 3. Preferably, the sliding groove 35 penetrates the mounting seat 3 from top to bottom. A connector 4 is slidingly provided in the mounting seat 3. In addition, a plurality of convex strips 34 are arranged at intervals on the side wall of the sliding groove 35. The side wall of the connector 4 fits with the convex strips 34. This can reduce the contact area between the connector 4 and the side wall of the sliding groove 35, thereby making the connector 4 move up and down more smoothly.

[0026] A socket 12 for the connector 4 to enter is provided on one side of the box body 1 corresponding to the rod assembly 2. Preferably, the socket 12 is located on the side wall of the accommodating groove 11. When the rod assembly 2 is rotated into the accommodating groove 11 and the connector 4 is inserted into the socket 12, the rod assembly 2 is locked in the accommodating groove 11 relative to the box body 1.

[0027] In addition, a first limiting portion is provided in the sliding groove 35 , and a second limiting portion is provided on the connector 4 . The first limiting portion cooperates with the second limiting portion to form a limiting structure for limiting the connector 4 from being separated from the sliding groove 35 .

[0028] Specific reference Figure 3 The first limiting portion includes an upper limiting platform 31 and a lower limiting platform 32 arranged in the sliding groove 35, and the second limiting portion includes an upper limiting block 41 and a lower limiting block 42 arranged on the connector 4; the upper limiting block 41 cooperates with the upper limiting platform 31 to limit the upward movement distance of the connector 4, and the lower limiting block 42 cooperates with the lower limiting platform 32 to limit the downward movement distance of the connector 4.

[0029] A notch is formed on one side of the sliding groove 35, and the bottom of the notch forms the above-mentioned lower limit platform 32; the lower limit block 42 protrudes outward to form a handle structure, which protrudes from the notch, thereby facilitating the user to operate the connector 4 to slide up and down.

[0030] In addition, a positioning groove 33 is provided in the sliding groove 35, and a positioning block that can extend into the positioning groove 33 is correspondingly provided on the connector 4. When the connector 4 slides up to the limit position, the positioning block just extends into the positioning groove 33, so that the connector 4 can be prevented from sliding freely.

[0031] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
