Abstract
The utility model relates to a connecting piece of a calash rod of a children's vehicle, comprising a first bar [1] and a second bar [7] which are rotarily connected through a turning cylinder [5]. The connecting piece of the utility model is characterized in that the second bar [7] is opened with an elongated sliding groove [8], and the first bar [1] is provided with the turning cylinder [5] which threads the sliding groove [8]. The turning cylinder [5] contacts one end of a spring [6], the first bar [1] is provided with a first bar block [3], and the second bar [7] is provided with a second bar block [2]. When the connecting piece is needed to be folded under open state, the two bars respectively receive forces in opposite directions figured by the accompanying diagram, and the forces facilitates the connecting piece of the utility model to complete folding action, without faulty operation, which is convenient for utilizing.
Description
Technical field
The utility model relates to the attaching parts between two ceiling bars of a kind of children trolley, particularly go-cart.
Background technology
In the prior art, the top, seat of go-cart is provided with ceiling, ceiling is made up of many coaxial ceiling bar and paulins, be provided with attaching parts between the adjacent ceiling bar, attaching parts comprises first rod member, second rod member, be rotatably connected by turning cylinder between described first rod member and second rod member, be provided with the first direction rotation stop device of first rod member under softened state between described first rod member and second rod member; The upper end of an adjacent ceiling bar is connected with the outer end phase pivot of first rod member, and the upper end of another root ceiling bar is connected with the outer end phase pivot of second rod member.This attaching parts has two kinds of mode of operations, and a kind of mode of operation is a softened state, and this moment, ceiling also was the state that struts, and another kind of mode of operation is a rounding state, and this moment, ceiling also was rounding state.This attaching parts is to rely on the principle at dead point to make it to strut, and makes described rotation stop device prevent two rod members to relatively rotate.This class formation damages when user's maloperation easily.
Summary of the invention
The purpose of this utility model is to provide a kind of attaching parts of ceiling bar of the children trolley that struts and draw in processing ease.
The technical solution of the utility model is: a kind of attaching parts of ceiling bar of children trolley, comprise first rod member, second rod member, be rotatably connected by turning cylinder between described first rod member and second rod member, be provided with the first direction rotation stop device of first rod member under softened state between described first rod member and second rod member; Have the strip shape sliding tray on described second rod member, described first rod member is provided with turning cylinder, this turning cylinder passes described sliding tray, described turning cylinder contacts with an end of spring, described second rod member contacts with the other end of spring, described first rod member is provided with the axial raised first rod member block to turning cylinder, described second rod member is provided with the axial raised second rod member block to turning cylinder, under softened state, the described second rod member block blocks the first rod member block on second rotation direction of first rod member; Under rounding state, the described second rod member block staggers mutually with the first rod member block on the rotation direction of first rod member.
The utility model compared with prior art has following advantage:
When attaching parts needs to draw under softened state, two rod members can be subjected to the power of relative direction shown in the drawings respectively, this power make turning cylinder overcome spring force along sliding tray left direction move, make the rod member block [3] of winning avoid the second rod member block, then first rod member (i.e. second rotation direction) rotation is in the counterclockwise direction finished and is drawn action in, promptly automatically attaching parts is drawn in when drawing paulin in, therefore maloperation can not appear, and easy to use.
Description of drawings
Accompanying drawing 1 is the structural front view of the utility model under softened state;
Accompanying drawing 2 is that the utility model is in the structural front view of preparing under the rounding state;
Accompanying drawing 3 is the structural front view of the utility model under the part rounding state;
Accompanying drawing 4 is the structural front view of the utility model under half rounding state;
The structural front view that accompanying drawing 5 is the utility model under rounding state basically; Wherein:
[1], first rod member; [2], the second rod member block; [3], the first rod member block; [4], the first rod member block passage; [5], turning cylinder; [6], spring; [7], second rod member; [8], sliding tray; [9], spring groove; [10], fluffy bar shaft hole.
The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 5, a kind of attaching parts of ceiling bar of children trolley, comprise first rod member [1], second rod member [7], be rotatably connected by turning cylinder [5] between described first rod member [1] and second rod member [7], be provided with first direction (the being clockwise direction) rotation stop device of first rod member [1] under softened state between described first rod member [1] and second rod member [7]; Have strip shape sliding tray [8] on described second rod member [7], described first rod member [1] is provided with turning cylinder [5], and this turning cylinder [5] passes described sliding tray [8], makes turning cylinder [5] move slidably in sliding tray [8], and is also rotatable.Described turning cylinder [5] contacts with an end of spring [6], described second rod member [7] contacts with the other end of spring [6], described first rod member [1] is provided with the axial raised first rod member block [3] to turning cylinder [5], described second rod member [7] is provided with the axial raised second rod member block [2] to turning cylinder [5], under softened state, the described second rod member block [2] blocks the first rod member block [3] on second rotation direction of first rod member [1]; Under rounding state, the described second rod member block [2] staggers mutually with the first rod member block [3] on the rotation direction of first rod member [1], and the first rod member block [3] can be pressed anticlockwise motion along the first other rod member block passage of the second rod member block [2].
Described spring [6] is arranged in the spring groove [9] on second rod member [7].
The outer end of described first rod member [1] and second rod member [7] is provided with fluffy bar shaft hole [10] respectively, and the upper end of two adjacent ceiling bars is connected with second rod member [7] phase pivot with described first rod member [1] respectively.
