Problems solved by technology

[0004] However, there is not much space between the handle 1a in the stored state and the bottom surface 2b of the recessed part 2a for the user to insert his hand, which makes it difficult to pull out the telescopic rod 1 for use. To solve this problem of inconvenient use , most operators will set up a pop-up structure (not shown in the figure) to cooperate with the telescopic rod 1, and press a button 3 to release the clamping relationship between the pop-up structure and the telescopic rod 1, and then use the spring of the pop-up structure to move upward Push the telescopic pull rod 1, causing the position of the handle 1a to be at a predetermined height relative to the box body 2 (such as figure 1 Indicated by the imaginary line), so that the gap between the handle 1a and the bottom surface 2b of the recessed part 2a increases, and the user's hand can easily penetrate and pull up the telescopic rod 1 for use.
[0005] Although the above-mentioned button 3 is the easiest and most convenient control switch to release the clamping relationship between the pop-up structure and the telescopic pull rod 1, the button 3 is easy to be mistakenly touched in an undefended situation, causing the telescopic pull rod 1 to bounce up automatically, or Although the button 3 is not pressed, when the suitcase is suddenly hit by an external force, the button 3 cannot effectively limit the bouncing structure and continues to engage with the telescopic rod 1 so that they are no longer stuck to each other, and the telescopic rod 1 will immediately Automatic pop-up, all of the above situations will cause part of the telescopic rod 1 to be exposed, which will increase the inconvenience of use

Embodiment Construction

[0036] The present invention is used for the protective structure of the pull rod of the luggage case with the function of bouncing up. The pull rod is used as a suitcase controlled by the button as the bouncing up control. The spring of the pop-up structure pushes the pull rod to make it bounce up to a predetermined height, and it is convenient for the user to hold the handle on the top of the pull rod so as to pull out the pull rod for use. This will not go into details, what is relevant to the present invention is the button, hereby narrate the relationship between the button and the pull bar protective structure of the present invention as follows:

[0037] Figure 2 to Figure 4 Shown is a protective structure for a luggage trolley with a pop-up function according to a preferred embodiment of the present invention. The trolley protective structure 20 has the function of preventing the trolley 10 from automatically bouncing up without warning when it is not controlled. It i...

Abstract

The invention relates to a protective structure of a trunk draw bar with bouncing function, and the protective structure of the draw bar is arranged outside a button which is used for controlling the automatic bouncing of the draw bar, and the purpose of covering or uncovering the button is achieved by position change of a sliding cover which can slide; when the button is covered, the button can be prevented from being touched falsely, conversely, people can touch and press the button to control the bouncing of the draw bar, so as to grip and pull out the draw bar conveniently.

Description

technical field [0001] The invention relates to a suitcase, more specifically, a protective structure for a trolley of a suitcase with the function of bouncing up. Background technique [0002] In addition to the development of light weight and durability in the design process of luggage, the convenience of use is also a design focus that cannot be ignored. [0003] Taking the telescopic pull rod as an example, it is convenient for the user to drag or carry the suitcase by utilizing its retractable feature. like figure 1 As shown, the telescopic pull rod 1 is installed at the back of the suitcase, and is stored inside the box body 2 when not in use, leaving only the handle 1a outside, and the box body 2 is preset with a recess at the position corresponding to the handle 1a. The part 2a is for accommodating the handle 1a, so as to maintain the overall aesthetic feeling of the suitcase. [0004] However, there is not much space between the handle 1a in the stored state and ...
