Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a safety handrail for a children's trolley case. Background Art

[0002] Children's riding trolley case is an innovatively designed travel or daily use suitcase designed specifically for children. It combines the functions of riding toys and traditional trolley cases. It not only has enough storage space to load children's clothes, toys and other necessities, but is also equipped with foldable footrests and handles. This type of children's trolley case will have safety handrails installed on the handle to provide children with a handle to hold when riding.

[0003] Publication No.: CN207544542U discloses a foldable children's chair trolley case, comprising a foldable children's chair trolley and a suitcase, wherein the foldable children's chair trolley comprises a hand pull rod, the hand pull rod is arranged on the back of the suitcase, a seat is arranged in the middle of the hand pull rod, an armrest is arranged between the hand pull rod and the seat, a bracket is arranged below the seat, a universal wheel is arranged at the bottom end of the bracket, a sleeve is provided at the lower end of the hand pull rod, the sleeve is fixed on the support assembly, and a roller is arranged below the support assembly. The trolley can be combined with and separated from the suitcase. The trolley case is equipped with double support rods and universal wheels, which can be pushed and pulled. The necessities for taking children out for travel and heavier items can be placed in the trolley case, which solves the weight and fatigue of adults holding children and carrying the above items when shopping in the mall for a long time. However, the safety handle has only symmetrical grip ends on both sides. Children can only hold the grip when riding, which is unsafe. Bumps are likely to occur during riding, and children will sway from side to side. The gripping force of children holding the handle alone is not enough to provide safety guarantees. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a safety armrest for a children's suitcase in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a safety armrest for a children's trolley case, comprising a connecting arm connected to the handle of the suitcase, characterized in that a first connecting member and a second connecting member are respectively provided at both ends of the connecting arm, the first connecting member and the second connecting member are detachably connected by a snap-fit ​​assembly, and a safety ring is also provided between the first connecting member and the second connecting member.

[0006] Using the above technical solution, the two ends of the connecting arm are respectively provided with a first connecting part and a second connecting part, and a detachable connection is achieved through a snap-on assembly, which is convenient for installation and maintenance. The two ends of the safety ring are fixedly connected to the first connecting part and the second connecting part, and can wrap the entire child around the installation ring, ensuring the safety of the entire armrest.

[0007] The above-mentioned safety armrest for a children's trolley case can be further configured as follows: the safety ring includes plug-in ends arranged at both ends of the safety ring, and the first connecting member and the second connecting member are both provided with plug-in slots for the plug-in ends on the side facing the plug-in ends, and the plug-in slots and the tops of the plug-in ends are both provided with fixing holes.

[0008] With the above-mentioned technical solution, plug-in ends are provided at both ends of the safety ring, and plug-in slots for insertion are provided on the side of the first connecting member and the second connecting member facing these plug-in ends, thereby ensuring that the safety ring can be tightly combined with the connecting member and improving the overall stability. Fixing holes are provided on the tops of the plug-in slots and the plug-in ends, and the connection is further reinforced by additional screws or pins to prevent loosening or falling off during use.

[0009] The above-mentioned safety armrest for a children's trolley case can be further configured as follows: the snap-fit ​​assembly includes a mounting piece arranged between a first connecting piece and a second connecting piece, the mounting piece is provided with a first cavity for axial installation of a button and a second cavity for installation of a lever arm and a snap-fit ​​piece, the first cavity and the second cavity are communicated with each other, the button is plug-connected with the lever arm, the snap-fit ​​piece is plug-connected with the lever arm, a first snap-fit ​​block is provided on one side of the snap-fit ​​piece, and a first snap-fit ​​groove is provided on one end of the second connecting piece facing the mounting piece to be plugged with the first snap-fit ​​block, and when the button is pressed, the snap-fit ​​piece is lifted by the lever arm to cause the first snap-fit ​​block to disengage from the first snap-fit ​​groove.

The third through-hole opened on one side of the first connecting member allows the button to pass through it and be fixed to the mounting member, while the second connecting member is fixed to the mounting member through the second clamping groove and the second clamping block, ensuring smooth and unobstructed operation of the button and a stable connection between the second connecting member and the mounting member.

[0013] The above-mentioned safety armrest for a children's suitcase can be further configured as follows: the first connecting member and the second connecting member are provided with sleeve holes on the side facing the connecting arm, and both ends of the connecting arm are provided with sleeve ends that are sleeved and installed in the sleeve holes.

[0014] By adopting the above technical solution, the first connecting member and the second connecting member are installed on the sleeve end of the connecting arm through the sleeve hole, realizing a connection method that is both stable and flexible. The first connecting member and the second connecting member are provided with sleeve holes on the side facing the connecting arm, so that the connecting arm can be tightly sleeved on the connecting member, thereby improving the stability of the overall structure. At the same time, when the safety handrail needs to be removed, the first connecting member and the second connecting member can be directly removed from the connecting arm, which facilitates the installation and removal of the safety handrail.

[0015] The above-mentioned safety armrest for a children's trolley case can be further configured as follows: a second through-hole for the external luggage trolley rod to pass through is provided at the center of the connecting arm, and the first connecting member and the second connecting member are both provided with connecting protrusions at one end facing the second through-hole, and the connecting protrusions are provided with semi-arc grooves, and the semi-arc grooves of the first connecting member and the second connecting member abut against each other to form an abutment groove for the external luggage trolley rod to abut against.

[0016] Using the above technical solution, a second through-hole is provided in the center of the connecting arm for the external luggage draw rod to pass through. This design enables the external luggage draw rod to pass through the connecting arm tightly, thereby improving the stability of the overall structure. The first connecting member and the second connecting member are both provided with connecting protrusions at one end facing the second through-hole, and these connecting protrusions are provided with semi-arc grooves. The semi-arc grooves are abutted together to form an abutment groove for the external luggage draw rod to abut, thereby ensuring the stability of the external luggage draw rod during the connection process.

[0017] The beneficial effects of the utility model are as follows: the two ends of the connecting arm are respectively provided with a first connecting piece and a second connecting piece, and a detachable connection is achieved through a snap-on assembly, which is convenient for installation and maintenance; the two ends of the safety ring are fixedly connected to the first connecting piece and the second connecting piece, and the child can be completely wrapped in the installation ring, thereby ensuring the safety of the entire armrest.
