Description
Technical field
The utility model relates to a kind of type simple door lock structure of dolly of playing, and belongs to lock device.
Background technology
The door latch structure of playing on dolly requires i.e. safety but also can open and close quickly and easily, and although existing door latch structure security performance of playing on dolly is protected, but but lose convenience, not the needs being applicable to play very much, therefore, for the problems referred to above be the utility model research object.
Summary of the invention
In order to solve existing technical deficiency, the utility model provides a kind of type simple door lock structure of dolly of playing.
The technical solution of the utility model is:
A kind of type simple door lock structure of dolly of playing, comprise the first pedestal of being located at and playing in trolley and be arranged on second pedestal of playing on little car door body, it is characterized in that: described first pedestal has been articulated with a blend stop, described second pedestal is hinged with a clamp, the upper end of described clamp has crook, and between the upper end of this crook and the second pedestal, form the bayonet socket installing blend stop movable end, a torsion spring is also provided with between described clamp and the second pedestal, one end apical grafting of described torsion spring is in the lower end of clamp, the other end apical grafting of described torsion spring is on the second pedestal.
Wherein, by a pinned connection between described second pedestal and clamp, and described torsion spring is nested with on described bearing pin.
The upside one-tenth of described clamp crook imports the skewed of bayonet socket in order to blend stop.
The movable end of described blend stop is provided with the handle of a protrusion.
The utility model has the advantage of: the utility model structure is simple, and simple operation, security performance is good, effectively can meet the needs opening and closing door of dolly of playing.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment,
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Referring to figs. 1 to Fig. 2, the utility model relates to a kind of type simple door lock structure of dolly of playing, comprise the first pedestal 1 of being located at and playing in trolley and be arranged on second pedestal 2 of playing on little car door body, described first pedestal is articulated with a blend stop 3, described second pedestal is hinged with a clamp 4, the upper end of described clamp has crook 10, and between the upper end of this crook and the second pedestal, form the bayonet socket 5 installing blend stop movable end, a torsion spring 6 is also provided with between described clamp and the second pedestal, one end apical grafting of described torsion spring is in the lower end of clamp, the other end apical grafting of described torsion spring is on the second pedestal.
Above-mentioned second pedestal is connected by a bearing pin 7 with between clamp, and described torsion spring is nested with on described bearing pin.
The upside of above-mentioned clamp crook becomes in order to blend stop importing bayonet socket skewed 8.
The movable end of above-mentioned blend stop is provided with the handle 9 of a protrusion.
Specific implementation process:
At needs at closing time, as long as rotation blend stop, it is made to drop in bayonet socket, utilize the hook formation of bayonet socket by spacing for blend stop in bayonet socket, thus play firm effect, the upside due to crook becomes skewed, utilizes self deadweight of blend stop to overcome spring force, make blend stop drop in bayonet socket, be convenient to common child and also can operate; When needs open the door, as long as press the lower end of pressure clamp, make upper end bayonet socket amplitude open greatly, take out blend stop.Such structure has taken into full account safety, namely would rather close the door, also nonvoluntary enabling, thus available protecting child.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
