The specific implementation mode is as follows:

the principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. In the description, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore, are not to be construed as limiting the patent.

As shown in the figure, the frame wide pull rod assembly comprises two telescopic pull rods arranged in parallel and a handle 1 connected with the two telescopic pull rods, wherein a telescopic control button is arranged on the handle 1, and each telescopic pull rod comprises a main pipe 4 and a sub pipe 2 inserted in the main pipe 4; the structure and the telescoping principle of the telescopic pull rod are well known to those skilled in the art and will not be described herein. A lower support 6 is arranged between the bottoms of the two telescopic pull rods, and an upper support 5 parallel to the lower support 6 is arranged between the lower support 6 and the handle 1; the upper support 5, the lower support 6 and the two telescopic pull rods form two parallel or vertical frame structures, so that the structure of the whole pull rod assembly is kept on the same horizontal plane, on one hand, the reinforcement effect is achieved, on the other hand, the relative parallelism among the pull rods can be guaranteed, and the telescopic effect is smooth. The frame structure is arranged inside the pull rod box body; and the lower support 6 is fixedly connected with the inner side of the bottom of the draw-bar box body, and the upper support 5 is fixedly connected with the inner side of the top of the draw-bar box body for installation. Wherein the two telescopic pull rods are close to the left inner side and the right inner side of the draw-bar box body but are not connected with the left inner side and the right inner side of the draw-bar box body. The principle is that the draw-bar box body is integrally formed by generally adopting a sheet type injection molding material, and the box body is difficult to avoid deformation after a large number of articles are loaded. After the conventional wide pull rod is connected with the left side and the right side of the box body, the main pipe 4 of the pull rod is easy to deform along with the deformation of the box body, so that the extension of the sub pipe 2 in the main pipe 4 is blocked, and the using effect is influenced. The draw bar assembly provided by the embodiment of the utility model is fixedly connected with the box body mainly on the four corners of the frame body, the upper support 5 and the lower support 6, and the draw bar is suspended relative to the left side and the right side of the box body, so that the influence of the deformation of the box body on the draw bar is avoided to the greatest extent, and the service life of the draw bar is prolonged; secondly simple structure, conventional wide draw-bar box, box often still need additionally set up the frame of the wide pull rod of holding, the embodiment of the utility model provides a cancel this type of design, further increased the volume of box.

Further, for reinforcing draw-bar box and this embodiment draw-bar assembly's joint strength, the upper bracket 5 is U type structure, and the interlude is the piece formula, keeps away from draw-bar box top one end and is equipped with the strengthening rib, and the interlude has stronger toughness and elasticity, can warp and kick-back along with the box. Similarly, the lower support 6 is designed into a U-shaped structure, and the middle section is a sheet type. One end of the lower support 6, which is far away from the bottom of the draw-bar box, is provided with a reinforcing rib, so that the reinforcement and the bearing capacity improvement are realized. The left end and the right end of the lower support 6 are provided with connecting seats 61 which are fixedly connected with the bottom end of the main pipe 4.

In some embodiments, the connecting seat 61 may be a separate component fixedly connected to the lower holder 6; in the present embodiment, the connecting base 61 is integrally formed with the lower holder 6.

Further, in order to prevent that the telescopic pull rod is subjected to violent impact in the using or transporting process, and the secondary pipe 2 is caused to cross the contraction limit in the primary pipe 4, thereby causing damage to the box body or the pull rod, the connecting seat 61 is provided with a butting limit 62. The abutting limit 62 can be realized by one or more combination modes of a bulge, a salient point, a convex edge, a blind hole and a clamping groove, and the abutting limit 62 is abutted against the sub-pipe 2 when the telescopic pull rod is in a contraction state or exceeds the limit of the contraction state. In some embodiments, the connecting seat 61 is a solid cylinder inserted into the main tube 4, and the top of the cylinder is a support limit 62 abutting against the sub-tube 2. In this embodiment, the connecting seat is a column, the top end of which is provided with a blind hole, the female pipe is inserted into the blind hole, and the bottom of the blind hole is a support limit 62.

Further, specifically speaking, the utility model discloses still relate to a draw-bar box that contains wide draw bar assembly of above-mentioned embodiment, including the box, the gyro wheel is established to the bottom half. The top of the box body is provided with two pull rod openings, the guide seat 3 is inserted in the pull rod openings, a guide hole 32 is formed in the middle of the guide seat 3, and the two telescopic pull rods penetrate through the guide hole 32 to extend out of the box body and are connected with the handle 1. The guide base 3 has a portion extending outside the case body and a portion remaining in the case body. The handle 1 is provided with a telescopic button, and when the handle is pressed, the sub-pipe 2 slides in the main pipe 4 to realize the extension of the pull rod. The upper side in the box body is provided with an upper support 5, and the lower side is provided with a lower support 6; the two telescopic pull rods are close to the left inner side and the right inner side of the box body but are not connected with the left inner side and the right inner side of the pull rod box body. The lower bracket 6 is connected with the bottom of the main pipe 4 through a connecting seat 61. Both ends and guide holder 3 riveting about the pop-up 5, two flexible pull rods pass through guide holder 3, pop-up 5, hold in the palm 6 down and are connected with the box realization. The upper support 5, the lower support 6 and the two telescopic pull rods are parallel or vertical to each other to form a frame body, and the frame body is supported in an encircling manner in the box body. The advantage of this kind of design lies in, and whole pull rod assembly's structure keeps on same horizontal plane, plays the reinforcement effect on the one hand, and on the other hand can ensure again between the pull rod relatively parallel to it is smooth and easy to stretch out and draw back. Meanwhile, when the wide pull rod is used as a handle or the box body is twisted through the wide pull rod, the upper support and the lower support can play a good role in force transmission, so that the box body is stressed more uniformly, and the deformation and the damage of the box body due to nonuniform stress are avoided.

Furthermore, in order to ensure that the upper support 5 and the lower support 6 can be arranged in parallel, positioning parts 51 are arranged at two ends of the upper support 5, and the positioning parts 51 are clamped with the guide seat 3.
