Description

Safety carriage for children

The utility model relates to a kind of perambulator.

In the prior art, perambulator comprises the vehicle frame be made up of foreleg and back leg, is arranged at the front-wheel and the trailing wheel of vehicle frame below, is arranged at the seat board on the vehicle frame, described vehicle frame is provided with a latch hook that rod member is rotatably connected with vehicle frame, this is rotatably connected with the rotating shaft of latch hook rotating shaft as both, and the preceding hook portion of this latch hook is hooked on the projection on another rod member on the vehicle frame; Perambulator can be folded up, and to be adapted to transportation and to deposit, when perambulator was opened, latch hook pinned projection, the rod member at projection and latch hook place be can relative motion when folding rod member.When the baby sits, lies on the seat board of perambulator, do not allow latch hook to discharge projection, otherwise can cause Pram folding and tumble injury, squeeze the child on the bad seat board.When perambulator does not allow child to be sitting in the car when latch hook hangs up properly projection under open mode yet.When but the latch hook of present perambulator is sitting on the seat board child,, use dangerous because maloperation or accidental external force still can be opened latch hook.

Thereby the purpose of this utility model is to provide a kind of latch hook that can not discharge when on the seat board baby being arranged to forbid Safety carriage for children folding under this state.

The technical solution of the utility model is: Safety carriage for children comprises the vehicle frame be made up of foreleg and back leg, is arranged at the front-wheel and the trailing wheel of vehicle frame below, is arranged at the seat board on the vehicle frame, described vehicle frame is provided with a latch hook that rod member is rotatably connected with vehicle frame, this is rotatably connected with the rotating shaft of latch hook rotating shaft as both, and the preceding hook portion of this latch hook is hooked on the projection on another rod member on the vehicle frame; It is the extension of center of rotation that the lower bottom part of described seat board is provided with the latch hook rotating shaft, and described seat board is pressed on this extension, and this extension and latch hook are connected to one.

The utility model compared with prior art has following advantage:

Because seat board is pressed on the extension, when child is on seat board, owing to child's weight makes the extension be pushed down and can not clockwise rotate by seat board, when attempting to make latch hook to discharge projection if press the latch hook back segment this moment, because it is that the axle center clockwise rotates with the latch hook rotating shaft that the leading portion of latch hook must drive the extension, therefore the latch hook back segment can't be depressed, and has guaranteed that also this moment can not release.When child leaves seat board, press down the latch hook back segment and then can support seat board and clockwise rotate in the extension, can finish unlocking operation.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural representation of the present utility model; The location drawing of seat board and lock an ancient unit of weight when double dot dash line is release;

Accompanying drawing 2 is that the structure of latch hook and extension and latch hook rotating shaft is implemented illustration;

Accompanying drawing 3 is that another structure of latch hook and extension and latch hook rotating shaft is implemented illustration; Wherein:

[1]. front-wheel; [2]. foreleg; [3]. seat board; [5]. latch hook; [7]. the latch hook rotating shaft; [8]. back leg; [9]. back leg; [10]. projection; [11]. the latch hook back segment; [12]. the extension.

Embodiment: referring to accompanying drawing 1, a kind of Safety carriage for children, comprise the vehicle frame formed by foreleg [2] and back leg [8], be arranged at the vehicle frame below front-wheel [1] and trailing wheel [9], be arranged at the seat board [3] on the vehicle frame, described vehicle frame is provided with the latch hook [5] that a rod member with vehicle frame is rotatably connected, this is rotatably connected with the rotating shaft of latch hook rotating shaft [7] as both, and the preceding hook portion of this latch hook [5] is hooked on the projection [10] on another rod member on the vehicle frame; It is the extension [12] of center of rotation that the lower bottom part of described seat board [3] is provided with latch hook rotating shaft [7], described seat board [3] is pressed on this extension [12], also distance that can be at interval very little 2 millimeter for example, this extension [12] is connected to one with latch hook [5], when rotating latch hook [5], described extension [12] also follow synchronous rotation.Can there be multiple structure described extension [12], and a kind of is as shown in Figure 1, and extension [12] are exactly described latch hook rotating shaft [7] latch hook leading portion before.Also having a kind of structure is as shown in Figure 3, and for being fixed in the extension forward in the latch hook rotating shaft [7], described latch hook rotating shaft [7] is connected to one with latch hook [5] described extension [12].The third structure is as shown in Figure 2, described extension [12] rod member for being connected to one with latch hook [5] and extending to the bottom of seat board [3].Distance between the front end of described extension [12] and the latch hook rotating shaft [7] is greater than the rear end of latch hook back segment [11] and the distance between the latch hook rotating shaft [7], so that when the baby is sitting on the seat board [3], press down latch hook back segment [11] and need very big power, this power is greater than baby's weight, and generally both length ratio is 3: 2.
