Specific embodiments
[0022] The present utility model will be further described below in conjunction with the accompanying drawings.
[0023] All orientations mentioned in this specification are based on the orientation of a handcart handrail assembly of the present utility model during normal operation, without limiting its orientation during storage and transportation, only representing relative positional relationships and not absolute positional relationships.
[0024] As Figure 1 and Figure 2 collectively shown, a handcart handrail assembly includes an arc-shaped handrail body 1, a sleeve 2 hinged to one side of the handrail body 1, and a plug-in box 3 inserted into the other side of the handrail body 1.
[0025] As Figure 2 , Figure 3 and Figure 4 collectively shown, one end of the handrail body 1 is provided with a hinge joint 11 hinged to the sleeve 2, and the other end is provided with a plug 12 inserted into the plug-in box 3.
[0026] The sleeve 2 is fixed on the column on one side of the handcart. During the assembly of the handcart, the sleeve 2 is sleeved on the column. A threaded hole is provided on the side wall of the sleeve 2, which communicates the inner cavity of the sleeve 2 with the outside. A tightening bolt is screwed into the threaded hole, and the sleeve 2 is fixed on the column by the tightening bolt. An articulated seat 21 hinged to the hinge joint 11 is provided on the side of the sleeve 2, and the hinge joint 11 is hinged on the articulated seat 21.
[0027] The plug-in box 3 includes a box body 31 fixed on the column on the other side of the trolley. A slot 32 is provided on the box body 31, and the plug 12 is inserted into the slot 32. A limiting structure is provided between the plug 12 and the slot 32. The limiting structure includes an elastic pin 33 slidably installed in the box body 31 and a limiting groove 121 provided on the plug 12 corresponding to the elastic pin 33. A reset spring 34 is provided between the elastic pin 33 and the box body 31. Through the spring force of the reset spring 34, the elastic pin 33 is inserted into the limiting groove 121, and the plug 12 is clamped in the slot 32. In order to ensure that the elastic pin 33 slides more smoothly, a slideway for the elastic pin 33 to slide is provided in the box body 31. A lever 35 is also provided on the elastic pin 33. When the lever 35 is moved, the elastic pin 33 exits the limiting groove 121.
[0028] In one embodiment, the lever 35 extends out of the box body 31 , and the lever 35 is manually pushed to drive the elastic pin 33 to withdraw from the limiting groove 121 , thereby releasing the limit set between the plug 12 and the slot 32 .
[0029] In another embodiment, Figure 2 , Figure 3 and Figure 4 As shown together, in order to prevent the baby from accidentally touching the lever 35 during play, causing the armrest body 1 to pop open, in this embodiment, a lever cavity 36 is provided on one side of the lever 35 in the box body 31, and the bottom of the lever 35 is inserted into the lever cavity 36.

The rotation of the key can drive the rotating shaft 371 to rotate, thereby driving the push plate 372 to rotate, and then pushing the lever 35 to move, driving the elastic pin 33 to withdraw from the limit groove 121, thereby releasing the limit set between the plug 12 and the slot 32.
[0030] The keyhole is a polygonal structure, which may be a cross slot structure, a hexagonal structure, etc., and the corresponding key also has this structure.
[0031] In order to simplify the process of inserting the armrest body 1 into the plug box 3 without the assistance of a key, a guide bevel 122 is provided at the top of the elastic pin 33 inserted into the slot 32 and in contact with the bottom of the plug 12. By pressing the guide bevel 122, the elastic pin 33 withdraws from the slot 32.
[0032] In order to increase the resistance of moving the rotating plate 37 and avoid accidental opening, a torsion spring (not shown in the figure) is installed between the rotating shaft 371 and the lever cavity 36.
[0033] like Figure 5As shown, a second mounting hole 38 is further provided on the box body 31. The upright column at the other end of the trolley is inserted into the second mounting hole 38, and a tightening bolt is also provided between the second mounting hole 38 and the upright column.
[0034] The outer side of the armrest body 1 is covered with an elastic material, which can be sponge or rubber material to avoid bruising the baby.
[0035] A kind of armrest assembly of the utility model solves the technical problem that the armrest of the existing trolley plays a certain blocking role for putting the baby in, resulting in an increase in the difficulty of putting the baby on the trolley. The utility model realizes quickly opening the armrest, facilitating putting the baby into the trolley and reducing the operation difficulty.
[0036] Certainly, the above description is not a limitation to the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the utility model should also belong to the protection scope of the utility model.
