Description

Technical Field

[0001] The utility model relates to the technical field of luggage accessories, and particularly relates to a folding cup holder applicable to luggage. Background Art

[0002] With the improvement of living quality, more and more people begin to pursue comfort during travel. When traveling, they will carry water cups or buy drinks such as milk tea and coffee that need to be held by hand. To facilitate carrying, luggage manufacturers have designed cup holders on the luggage body. For example, the utility model patent with the patent application number CN202223377279.4 discloses a folding cup holder for luggage, which includes an installation fixing seat, a cup bottom bracket, and a cup body anti-tilting sleeve. The cup body anti-tilting sleeve is provided with a placement hole through which the cup can pass. The cup bottom bracket and the cup body anti-tilting sleeve are respectively hinged at opposite ends of the installation fixing seat. A transmission rod is connected between the cup bottom bracket and the cup body anti-tilting sleeve, and the transmission rod links the cup bottom bracket and the cup body anti-tilting sleeve. An elastic member for driving the cup body anti-tilting sleeve to automatically flip and open is provided between the cup body anti-tilting sleeve and the installation fixing seat, and a self-locking device is provided between the cup body anti-tilting sleeve and the installation fixing seat.

[0003] In actual production and use, it is found that the folding cup holder has the following disadvantages: 1. Pressing the clamping joint of the cup body anti-tilting sleeve and pressing the self-locking buckle to release the self-locking. Such an unlocking method is not obvious enough. For people who are not familiar with this type of luggage, they cannot quickly open the cup holder, which affects the use experience. 2. When producing a luggage with this folding cup holder, a luggage shell is obtained through the thermoforming process, and at the same time, a groove for assembling and installing a fixing frame is obtained on the panel of the shell. However, in production, it is very easy to have a thermoforming failure, resulting in damage to the bottom of the groove. Such a folding cup holder has high requirements for the production process of the luggage shell, resulting in an increase in production cost and a decrease in production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a folding cup holder applicable to luggage with a more intuitive unlocking method, change the process of installing the folding cup holder on the luggage, and improve the overall production efficiency in view of the above-mentioned deficiencies of the prior art.

[0005] To achieve the above object, the present utility model provides the following technical solution: A folding cup holder applicable to a luggage case, comprising an installation and fixing frame, a cup bottom bracket, and a cup body anti-tilting sleeve. A placement hole for the cup body to pass through is provided on the cup body anti-tilting sleeve. The cup bottom bracket and the cup body anti-tilting sleeve are respectively hinged to opposite ends of the installation and fixing frame. A transmission rod is connected between the cup bottom bracket and the cup body anti-tilting sleeve, and the transmission rod links the cup bottom bracket and the cup body anti-tilting sleeve. An elastic member for driving the cup body anti-tilting sleeve to automatically flip and open is provided between the cup body anti-tilting sleeve and the installation and fixing frame. A self-locking device is provided between the cup body anti-tilting sleeve and the installation and fixing frame. The self-locking device includes a self-locking key installed on the installation and fixing frame and capable of being toggled, and a self-locking seat linked to the self-locking key and capable of sliding in the installation and fixing frame. At least one self-locking block that moves up and down in the vertical direction under the drive of the self-locking seat is provided on the installation and fixing frame. After the self-locking block extends out of the installation and fixing frame, it is inserted into the cup body anti-tilting sleeve to achieve self-locking. A return spring for driving the self-locking key to reset is provided in the self-locking seat.

[0006] The present utility model with the above characteristics: By providing a self-locking key that can be toggled on the installation and fixing frame, users can directly observe and operate the self-locking key to open the folding cup holder. Such a toggling unlocking method is more intuitive and improves the user's convenience of use; the self-locking block and the cup body anti-tilting sleeve are self-locked by means of insertion, which can effectively prevent the folding cup holder from opening during the transportation of the luggage case.

[0007] A further setting of the present utility model is: The self-locking block includes a lock block body and a triangular insertion block provided on the end face of the lock block. An insertion slot for inserting the lock block body is provided in the installation and fixing frame. A trapezoidal slot for inserting the insertion block is provided on the self-locking seat. The trapezoidal slot includes a first waist arranged in the vertical direction, a second waist arranged in the horizontal direction, and an upper base and a lower base arranged obliquely. The insertion block includes a first right-angled side that can coincide with the first waist, a second right-angled side that can coincide with the second waist, and a hypotenuse that remains coincident with the lower base. An insertion slot for inserting the self-locking block is provided in the installation and fixing frame.

[0008] The present utility model with the above characteristics: The linkage between the self-locking seat and the self-locking block is realized by providing a trapezoidal slot in the self-locking seat and a matching triangular insertion block on the self-locking block. This structure converts the lateral movement of the self-locking seat into the vertical movement of the self-locking block, so that toggling the self-locking key can unlock, simplifying the self-locking structure; an insertion slot is provided in the installation and fixing frame to guide the movement of the self-locking block.

[0009] A further setting of the present utility model is as follows: The self-locking key includes a key body and two vertically distributed plug plates arranged on one side surface of the key body. The two plug plates are arranged in parallel. A key slot is provided on the installation and fixing seat for the plug plates to pass through and move therein. A clamping groove is provided on the plug plate, and clamping blocks adapted to the clamping groove are provided on both the upper and lower side surfaces of the self-locking seat.

[0010] For the present utility model having the above characteristics: The connection between the self-locking key and the self-locking seat is realized through the clamping groove and the clamping block. This connection structure is simple and convenient for installation; the two vertically distributed plug plates cooperate with the key slot to form a surface-to-surface contact structure, improving the stability of the plug plate when moving in the key slot.

[0011] A further setting of the present utility model is as follows: The installation and fixing frame includes a frame body and an annular panel arranged on one end surface of the frame body. The outer periphery of the annular panel is wider than the outer periphery of the frame body, and the inner periphery of the annular panel is narrower than the inner periphery of the frame body. The inner periphery of the annular panel is adapted to the shape of the anti-tipping sleeve of the cup body.

The connecting holes and the connecting pipes are detachably connected through fasteners.

[0012] For the present utility model having the above characteristics: By setting the annular panel and the installation box, the process of installing the folding cup holder on the luggage is changed. Only an installation slot needs to be opened on the luggage shell after thermoforming for placing the frame body, and the annular panel is in contact with the luggage shell to complete the installation of the folding cup holder. There is no need to simultaneously thermoform a groove for assembling the installation and fixing frame when thermoforming the luggage shell. This reduces the requirements for the thermoforming process of the luggage shell and improves production efficiency; the setting of the installation box can protect the internal structure of the folding cup holder.

[0013] A further setting of the present utility model is as follows: The anti-tipping sleeve of the cup body includes a sleeve body and a first connecting portion. First rotating shafts for hinging with the installation and fixing frame are provided at both ends of the first connecting portion.
