The pull rod top seat and the fixing component are fixedly connected by a first fastener and a second fastener. The first fastener is used to restrict the movement of the fixing component in the front-back direction, and the second fastener is used to restrict the movement of the fixing component in the up-down direction. When manufacturing suitcases, operators need to assemble the first fastener and the second fastener separately, which is complicated and affects the assembly efficiency of the suitcases.

[0025] Reference Figures 1 to 6According to a first aspect of the present invention, a suitcase includes a rear body 100, a pull rod base 200, an outer rod 300, an inner rod 400, a pull rod top seat 500, a fixing member 600, fasteners, and a limiting structure. The rear body 100 has a receiving cavity 110, and the top wall of the receiving cavity 110 has a notch 120. The pull rod base 200 is connected to the rear body 100. The outer rod 300 is disposed in the receiving cavity 110, one end of the outer rod 300 is fixedly connected to the pull rod base 200, one end of the inner rod 400 is movably disposed in the outer rod 300, and the other end of the inner rod 400 extends out of the receiving cavity 110 through the notch 120. The pull rod top seat 500 is fixedly connected to the outer rod base 200. The outer rod 300 is attached to the end away from the pull rod base 200. The pull rod top seat 500 is located on the outside of the rear box 100. The fixing member 600 is located in the receiving cavity 110. A part of the rear box 100 is sandwiched between the pull rod top seat 500 and the fixing member 600. Fasteners are connected between the pull rod top seat 500 and the fixing member 600. The fasteners are used to restrict the movement of the fixing member 600 in the front-back direction. A limiting structure is located between the pull rod top seat 500 and the fixing member 600. The limiting structure is used to restrict the movement of the fixing member 600 in the up-down direction. In this way, the number of fasteners can be reduced, thereby simplifying the installation steps of the fixing member 600 and improving the assembly efficiency of the suitcase.

[0026] For example, when assembling a suitcase, the pull rod base 200 is installed on the rear box 100, with the pull rod top seat 500 located on the outside of the rear box 100. Then, the fastener 600 is installed on the pull rod top seat 500 to connect the limiting structure, thereby restricting the movement of the fastener 600 in the vertical direction. Finally, the pull rod top seat 500, the rear box 100, and the fastener 600 are connected and fixed by fasteners, thus completely fixing the outer rod 300. When the user extends or retracts the inner rod 400, the outer rod 300 does not move relative to the rear box 100. This eliminates the need for the traditional method of connecting and fixing the outer rod 300 with the first and second fasteners, reducing the number of fasteners and simplifying the installation steps of the fastener 600, thereby improving the assembly efficiency of the suitcase.

[0027] It should be noted that fasteners can be screws or bolts, etc., and there are no restrictions on this.

[0028] It should be noted that the suitcase also includes a front compartment, which is rotatably connected to the rear compartment 100, or the front compartment and the rear compartment 100 are connected by an aluminum frame strip, which will not be described in detail here.

[0029] In some embodiments of this utility model, the limiting structure includes a limiting groove 501 provided on the top seat 500 of the pull rod and a limiting protrusion 610 provided on the fixing member 600. The limiting protrusion 610 is accommodated in the limiting groove 501 and abuts against the side wall of the limiting groove 501, which can restrict the fixing member 600 from moving in the up and down direction, thereby simplifying the assembly steps of the fixing member 600.

[0030] For example, when installing the fastener 600, the limiting protrusion 610 is inserted into the limiting groove 501, and the limiting protrusion 610 abuts against the side wall of the limiting groove 501, which can restrict the fastener 600 from moving in the vertical direction, thereby simplifying the assembly steps of the fastener 600.

[0031] It should be noted that the positions of the limiting protrusion 610 and the limiting groove 501 can be interchanged. That is, the limiting protrusion 610 can be located on the top seat 500 of the pull rod, and the limiting groove 501 can be located on the fixing member 600. As long as the fixing member 600 can be restricted to move in the up and down direction, no restrictions are imposed here.

[0032] As another implementation direction, the limiting structure can also be a structure in which the limiting pin and the limiting groove 501 cooperate, and no restrictions are imposed here.

[0033] In some embodiments of this utility model, the pull rod top seat 500 includes a connecting seat 510 and two connecting sleeves 520. The two connecting sleeves 520 are arranged side by side with intervals in the left-right direction. The connecting seat 510 is connected between the two connecting sleeves 520. There are two corresponding outer rods 300 and inner rods 400. The two connecting sleeves 520 are respectively sleeved on the outer periphery of the corresponding outer rod 300. The outer periphery of the connecting sleeve 520 is provided with a limiting groove 501, which can facilitate the connection and fixation of the two outer rods 300.

[0034] In some embodiments of this utility model, the connecting seat 510 and the connecting sleeve 520 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the suitcase.

[0035] For example, the connector 510 and the connector sleeve 520 can be integrally molded by injection molding, which can reduce the number of molds, thereby reducing the production cost of the molds and thus reducing the production cost of the suitcase.

[0036] It should be noted that the connector 510 and the connector sleeve 520 can also be connected by welding. The welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding, and is not limited here.

[0037] In some embodiments of this utility model, the connecting seat 510 is provided with a connecting post, the connecting post is provided with a threaded hole 512, the threaded hole 512 extends in the front-back direction, the fastener passes through the fixing member 600 and is threadedly engaged with the threaded hole 512. By providing the connecting post, the contact area between the fastener and the connecting seat 510 can be increased, thereby improving the connection reliability between the fastener and the connecting seat 510.

[0038] For example, there are two connecting posts, which are arranged side by side and spaced apart in the left and right direction. The fastener passes through the fixing part 600 and is threaded into the corresponding threaded hole 512, which can increase the contact area between the fastener and the connecting seat 510 and improve the connection reliability between the fastener and the connecting seat 510.

[0039] In some embodiments of this utility model, a first reinforcing rib 513 is provided between the connecting column and the connecting seat 510, which can improve the structural strength of the connecting column and thus improve the service life of the tie rod top seat 500.

[0040] For example, multiple first reinforcing ribs 513 are configured, and the multiple first reinforcing ribs 513 are spaced apart around the axis of the connecting column, which can improve the structural strength of the connecting column, prevent the connecting column from breaking, and thus improve the service life of the tie rod top seat 500.

[0041] In some embodiments of this utility model, each connecting sleeve 520 is provided with limiting grooves 501 on its left and right sides, so that the connecting sleeve 520 is subjected to uniform force, which can improve the connection reliability between the connecting sleeve 520 and the fixing member 600.

[0042] For example, in the left-right direction, the connecting sleeve 520 is provided with limiting grooves 501 on both sides, and the fixing member 600 is provided with limiting protrusions 610. The limiting protrusions 610 are accommodated in the corresponding limiting grooves 501, so that the connecting sleeve 520 is subjected to uniform force, which can improve the connection reliability between the connecting sleeve 520 and the fixing member 600.

[0043] In some embodiments of this utility model, the side wall of the limiting groove 501 is provided with a relief groove 502, and the fixing member 600 is provided with a second reinforcing rib 620 connecting the limiting protrusion 610. The second reinforcing rib 620 is accommodated in the relief groove 502. On the one hand, it can improve the structural stability of the limiting protrusion 610. On the other hand, the relief groove 502 can avoid the second reinforcing rib 620, so as to avoid interference between the second reinforcing rib 620 and the connecting sleeve 520, and facilitate the assembly of the fixing member 600.

[0044] In some embodiments of this utility model, the outer rod 300 is provided with a limiting block 310, and the connecting sleeve 520 is provided with a limiting hole 521. The limiting block 310 is accommodated in the limiting hole 521 and abuts against the side wall of the limiting hole 521, which facilitates the connection and fixation of the outer rod 300.

[0045] For example, the limiting block 310 has a wedge-shaped structure. The limiting block 310 is housed in the limiting hole 521 and abuts against the side wall of the limiting hole 521. This can limit the axial movement of the pull rod top seat 500 along the outer rod 300 and facilitate the connection and fixation of the outer rod 300.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
