Abstract

The utility model relates to an automatic-falling mechanism for a front tray of a baby's bassinet. A front leg (1) is rotatablely connected with a front tray (2) through a front tray rotating shaft (4), and the upper end of the front leg (1) is fixedly connected with a connecting piece (3); the upper end of a rear leg (7) is rotatablely connected with the connecting piece (3). The utility model is characterized in that a locking mechanism is arranged between the front tray (2) and the connecting piece (3); when a bassinet is converted to a folding state form an opening state, the locking mechanism is converted to an unlocking state from a locking state. When the bassinet is folded, the locking mechanism automatically unlocks and then the front tray automatically falls to a folding state by means of the action of gravity so that the total volume of the folded bassinet is decreased.

Description

The automatic lowering mechanism of the front tray of doll carriage

The utility model relates to the front tray of a kind of doll carriage, particularly doll carriage.

In the prior art, by the front tray rotating shaft front tray that has been rotatably connected, the upper end of described foreleg is fixedly connected with attaching parts on a kind of foreleg of doll carriage, and the upper end of back leg and described attaching parts are rotatably connected; When go-cart is under the open mode, the use surface of front tray roughly is horizontal, as shown in Figure 1, when Folding trolley, described front tray can not change the angle of itself and foreleg, therefore need take off front tray to reduce the volume after folding of go-cart, the front tray that still installs or removes is the pretty troublesome thing of part.

It is a kind of when Folding trolley that the purpose of this utility model is to provide, and front tray can be drawn close the automatic lowering mechanism of front tray of the doll carriage of foreleg as far as possible.

The technical solution of the utility model is: the automatic lowering mechanism of a kind of front tray of doll carriage, on the foreleg by the front tray rotating shaft front tray that has been rotatably connected, the upper end of described foreleg is fixedly connected with attaching parts, and the upper end of back leg and described attaching parts are rotatably connected; Be provided with lockout mechanism between described front tray and the described attaching parts; Go-cart is in open mode and described lockout mechanism is in the lock state down, and the running surface of described front tray roughly is horizontal; Go-cart is in folded state and described lockout mechanism is under the released state, and the leading section of described front tray falls to the position of as far as possible close described foreleg; When folded state was changed, described lockout mechanism was transformed to released state by lock-out state by open mode in go-cart.

The utility model compared with prior art has following advantage:

When go-cart is under the open mode, front tray can be horizontal haply and be made front tray be in stabilized conditions by the lockout mechanism locking.When described go-cart is folding, the lockout mechanism automatic unlocking, then front tray relies on the effect of gravity to fall to rounding state automatically, and the cumulative volume after making go-cart folding reduces.

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

Accompanying drawing 1 is that front tray of the present utility model is in horizontal service position roughly, and go-cart is in the structural front view under the open mode;

Accompanying drawing 2 is the control position that front tray of the present utility model is in gathering, and go-cart is in the structural front view under the folded state;

Accompanying drawing 3 is that the A of accompanying drawing 1 is to view;

Accompanying drawing 4 is that the B of accompanying drawing 2 is to view;

Accompanying drawing 5 is the K-K direction view of accompanying drawing 2; Wherein:

[1], foreleg; [2], front tray; [3], attaching parts; [4], front tray rotating shaft; [5], lock; [6], guiding surface; [7], back leg; [8], the pivot of foreleg and back leg; [9], button; [10], spring;

Embodiment: referring to accompanying drawing 1 to accompanying drawing 5, the automatic lowering mechanism of a kind of front tray of doll carriage, foreleg [1] is gone up by front tray rotating shaft [4] front tray [2] that has been rotatably connected, the upper end of described foreleg [1] is fixedly connected with attaching parts [3], and the upper end of back leg [7] and described attaching parts [3] are rotatably connected; Be provided with lockout mechanism between described front tray [2] and the described attaching parts [3].Referring to accompanying drawing 1 and accompanying drawing 3, go-cart is in open mode and described lockout mechanism is in the lock state down, and the running surface of described front tray [2] roughly is horizontal.Referring to accompanying drawing 2 and accompanying drawing 4, go-cart is in folded state and described lockout mechanism is under the released state, and the leading section of described front tray [2] falls to the position of as far as possible close described foreleg [1].

Referring to accompanying drawing 3 and accompanying drawing 4, when folded state was changed, described lockout mechanism was transformed to released state by lock-out state by open mode in go-cart.Described lockout mechanism is that the upper end of described back leg [7] is provided with guiding surface [6], and this guiding surface [6] contact has lock [5], described lock [5] and described attaching parts [3] sliding block joint.When rotating foreleg [1] and back leg [7] around the pivot [8] of foreleg and back leg when relatively rotating, described guiding surface [6] promotes described lock [5] and slides, owing to be provided with spring [10] between described lock [5] and the described attaching parts [3], after lock [5] had overcome the elastic force of spring [10], described lock [5] moved axially and makes lockout mechanism release or locking; Be in the lock state down at lockout mechanism, an end of described lock [5] is inserted in the described front tray [2] (referring to accompanying drawing 3).

Claims
