The specific implementation mode is as follows:

the principles and features of the present invention will be described with reference to the accompanying fig. 1-5, which are provided for illustration only and are not intended to limit the scope of the invention. In the description herein, it is to be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the positional or orientational relationships indicated in the drawings to facilitate the description of the patent and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the patent.

As shown in the figure, the utility model discloses a draw-bar box with put frame in specifically, including two cavity half box 1 that the symmetry set up, connect frame 4, scalable pull rod 3, handle 2 of two half box 1 and be located the case wheel 6 of two half box 1 bottoms. The two half-boxes 1 and the frame 4 constitute a complete hollow cavity. The opening of the draw-bar box of the embodiment is arranged on one of the two symmetrical semi-box bodies 1; the opening may be closed by means of a zipper or a snap-fit. When the zipper is unzipped or the clamping structure is undone, the hollow cavity in the draw-bar box can be accessed. As shown in fig. 1, this embodiment discloses a solution in which an end cap is snapped to close an opening. The inner walls of the left side and the right side of the frame 4 are axially oppositely provided with rod sleeves 5, and the rod sleeves 5 are tightly attached to the inner walls of the two sides of the frame 4. One end of the telescopic pull rod 3 is inserted into the rod sleeve 5, and the other end of the telescopic pull rod passes through a pull rod hole 41 on the upper side of the frame 4, extends out of the frame 4 and is connected with the handle 2; the outer wall of the upper side of the frame 4 is also provided with a handle groove 42 for accommodating the pull rod handle 2.

When the handle 2 is retracted and accommodated in the handle groove 42, the top end of the handle 2 is flush with the outer side wall of the top end of the frame 4, so that the handle 2 is retracted and then is integrated with the frame 4, and the whole structure is flat and beautiful. After the installation is finished, the telescopic pull rod 3 is connected with the frame 4 to bear force and is positioned in the middle of the luggage case. When the box is pulled, the telescopic pull rod 3 does not need to bear the weight of the whole draw-bar box, the pull rod is not easy to bend, and the use is labor-saving and convenient.

Further, the front end and the rear end of the frame 4 are respectively clamped or riveted with the half box body 1 in the circumferential direction; 4 circumference outer walls of frame after connecting keep flushing with half box body outer wall, so design for the frame agrees with the box junction, as integrated into one piece, and overall structure is more level and more smooth pleasing to the eye.

Further, the axial terminal surface outside that frame 4 and half box 1 are connected is equipped with along the bellied first connecting portion 43 of axial, the axial terminal surface inboard is equipped with bellied second connecting portion 44, form joint groove 45 between first connecting portion 43 and the second connecting portion 44, half box 1 the link is equipped with the embedding the third connecting portion 11 of joint groove 45 for connection structure is inseparabler firm, and the closure is better. In some embodiments, rivets are passed through the first connecting portion 43, the third connecting portion 11 and the second connecting portion 44, effecting riveting of the half-case 1 and the frame 4.

In this embodiment, the frame 4 and the half box 1 are clamped, and specifically includes a locking groove 46 opened on the second connecting portion 44 and leading to the clamping groove 45, and a first protruding locking member 47 is provided on the inner wall of the first connecting portion 43 corresponding to one side of the locking groove 46; and a second locking part 12 which is matched and clamped with the first locking part 47 is arranged on the third connecting part 11. Wherein, the locking groove 46 provides sufficient avoiding space for the smooth clamping of the first locking member 47 and the second locking member 12, so that the installation is more convenient, and the connecting part can be designed to be more stable.

The telescopic pull rod 3 comprises a middle pipe 31, an inner pipe 32, a locking mechanism 33 and a driving mechanism, wherein the inner pipe and the locking mechanism 33 are arranged in the middle pipe 21 in a sleeved mode, a control button 21 is arranged on the handle 2 and used for being linked with the driving mechanism, so that the locking mechanism 33 is controlled to be unlocked and locked, and the inner pipe 32 and the middle pipe 31 are driven to stretch and slide up and down in the rod sleeve 5. The locking mechanism used in this embodiment is 33 that is used in a conventional telescopic pull rod in the prior art, and the principle is disclosed, and is not further described herein.

Further, in the conventional design, when the handle 2 is received in the handle groove 42, the handle groove 42 should be reserved with a space for a user to hold the handle 2, and the reserved space is not beautiful and further occupies the originally received space. Therefore, the structural design of the portable reserved position is cancelled in the embodiment. And because when the handle 2 is contracted and accommodated in the handle groove 42, the handle 2 is tightly attached to the handle groove 42 and is inconvenient to pull out, a bouncing device for automatically lifting the telescopic pull rod is arranged in the rod sleeve 5. The specific structure of the bouncing device comprises a spring 34 which is arranged in the rod sleeve 5 through a mounting part 35, wherein one end of the spring 34 is propped against the mounting part 35, and the other end is propped against the bottom of the middle pipe 31. In the initial state of the handle 2 being accommodated, the spring 34 is located in a compressed state between the mounting member 35 and the bottom of the center tube 31. The button 21 is pressed once, the locking mechanism 33 is unlocked, the middle pipe 31 and the inner pipe 32 sleeved in the middle pipe 31 automatically bounce under the action of the spring 34, the handle 2 is driven to automatically lift, and a user can hold the handle conveniently.

Furthermore, a limit groove 51 is formed in the side wall of the rod sleeve 5, the middle pipe 31 is automatically lifted under the action of the spring 25, the locking mechanism 33 is driven to lift to the limit groove 51, the locking mechanism 33 pops out a bolt for locking and is limited in the limit groove 51, and the middle pipe 31 and the inner pipe 32 slide up and down along the length range of the limit groove 51. When the button 21 is pressed again, the locking mechanism 33 can be disengaged from the limiting groove, and conventional telescoping is realized.

The present invention is not limited to the above embodiment, and if various modifications or variations of the present invention are not departed from the spirit and scope of the present invention, provided they fall within the scope of the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include such modifications and variations.
