detailed description

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and not intended to limit the scope of the present invention. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present invention.

Referring to Fig. 1 and Fig. 2, the trolley case 100 provided by the utility model includes a case body 10, universal wheels 20 and handles 30 arranged at two opposite ends of the case body 10, and assembled on the case body 10 and connected with the handle 30 The telescopic pull rod 40 on the same side of the box body 10, in this embodiment, the telescopic pull rod 40 is assembled on the box body 10, specifically can be bent and fixed relative to the box body 10, that is, this embodiment The telescopic pull rod 40 of the trolley case 100 can be arranged obliquely relative to the case body 10 .

For the convenience of subsequent explanations, this embodiment defines the position on the box body 10 for assembling the telescopic pull rod 40 as an assembly hole (not shown in the figure), so it can be understood that the assembly of the telescopic pull rod 40 on the box body 10 is specifically Extending into the assembly hole of the box body 10.

In this embodiment, the telescopic pull rod 40 is connected to a rod seat 41 in a flexible connection on one end surface protruding into the assembly hole on the box body 10, and the telescopic pull rod 40 and the rod seat 41 are preferably hinged. way to connect. The outer diameter of the rod seat 41 is larger than the diameter of the opening of the assembly hole, that is, the rod seat 41 is always limited in the assembly hole of the box body 10 . It can be understood that a switch 42 is provided on the handle portion of the telescopic pull rod 40 to control whether the telescopic pull rod 40 is pulled out from the assembly hole of the box body 10 .

It can be seen from the above that when people use the trolley case 100, they can first pull out the telescopic rod 40 from the assembly hole of the case body 10 until the rod seat 41 is limited by the opening of the assembly hole on the case body 10, Then bend an angle P toward the direction where the handle 30 is located and limit and fix it. Correspondingly, the box body 10 is provided with two inclined slots 11 at a position between the assembly hole and the handle 30 to respectively correspond to the two straight rod portions of the telescopic pull rod 40 . It should be noted that when the telescopic pull rod 40 of this embodiment is bent relative to the box body 10, the bending direction is specifically toward the direction where the handle 30 is located. 100 is determined by the actual needs of driving. In order to achieve the above-mentioned bending orientation of the telescopic pull rod 40, it can be specifically achieved through the length structure of the two end faces of the end of the telescopic pull rod 40 connected to the rod seat 41. No further description is given here.

In this embodiment, the box body 10 is provided with a limiting convex portion (not shown in the figure) at the opening of the assembly hole, and the limiting convex portion is movably connected with the rod seat 41 on the telescopic pull rod 40 . The side ends are matched, so that when people drive the telescopic pull rod 40 to bend relative to the box body 10, the telescopic pull rod 40 in the bent state and The limit between the casings 10 is fixed.

As a preferred solution of the present utility model, the box body 10 is also provided with a circular arc protrusion 12 at the position between the assembly hole and the handle 30, and when the telescopic pull rod 40 is bent at an angle P relative to the box body 10 and limited When the position is fixed, the arc convex portion 12 protrudes outward relative to the telescopic pull rod 40 . In this way, when people use the trolley case 100, they can use the bent telescopic pull rod 40 as a backrest, and the arc convex post 12 as a corner, and place an IPAD or a mobile phone on it, so that people can use it. Further, the box body 10 is provided with arc protrusions 12 on both sides of the two inclined slots 11 . Correspondingly, in the trolley case 100 of this embodiment, the angle at which the telescopic rod 40 is bent relative to the box body 10 is further limited, so that the mobile phone or IPAD can be placed on the telescopic rod 40 in the bent state, and can be rounded. Limited by the arc protrusion 12, in this embodiment, the bending angle P of the telescopic pull rod 40 relative to the box body 10 is preferably 20°-60°.

As a preferred solution of the present utility model, the box body 10 is equipped with a ground crawler 50 on the side adjacent to the assembly hole, and the ground crawler is partially protruded outward relative to the box body 10, so that when people use the pull rod When the box 100 passes the inclined ground or steps, the grounding track 50 can be used to contact the inclined ground or steps, and then the trolley case 100 can be pulled with the telescopic pull rod 40 bent relative to the box body 10. Great labor saving effect.

To sum up, the trolley case provided by the utility model connects the telescopic trolley to the rod seat in a flexible manner, so that when the trolley case is in use, the telescopic trolley can be driven to bend and fix relative to the box body, In this way, the inclined driving of the trolley case by people through the telescopic trolley is realized, and the utility model has a labor-saving function. It is not only suitable for driving the trolley case on the flat ground, but also on the sloping ground or even on the steps through the telescopic pull rod.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall include Within the protection scope of the utility model.
