Embodiment
In order to explain more fully enforcement of the present utility model, embodiment of the present utility model is provided, these embodiments only are the elaborations to this device, do not limit scope of the present utility model, accompanying drawing of the present utility model does not consist of any restriction of the present utility model with explanation of the present utility model and the understanding of opposing.
As shown in drawings, a kind of amounting to prevents back taking off linkage structure, comprise connecting body A and connecting body B, be provided with circle hole shape attachment hole and arc anti-slip tank on the connecting body A10, be provided with cylindrical connection bump and the anti-skidding projection of arc on the connecting body B20, during connection, cylindrical connection bump on the connecting body B20 is pressed into the circle hole shape attachment hole on the connecting body A10, the anti-skidding projection of arc on the connecting body B20 enters the arc anti-slip tank on the connecting body A10 simultaneously, connecting body A10 adopts elastic material to make, such as engineering plastics or stalloy etc., connecting body A and connecting body B other position except interconnecting the position can connect the structure of any shape, be provided with left attachment hole 1 on the described connecting body A10 as shown in Figure 1, right attachment hole 2, left anti-slip tank 3, right anti-slip tank 4, as shown in Figure 4, be provided with left connection bump 5 on the described connecting body B20, right connection bump 6, left anti-skidding protruding 7, right anti-skidding protruding 8, connecting body A is connected with connecting body B and the position that rotates adopts hollow out to process when making, reserve enough connections and revolution space, during connection, because connecting body A10 and connecting body B20 adopt elastic material to make, connecting body B20 can be with defeating into connecting body A10, at this moment left connection bump 5 enters left attachment hole 1, right connection bump 6 enters right attachment hole 2, left anti-skidding protruding 7 enter left anti-slip tank 3, and right anti-skidding protruding 8 enter right anti-slip tank 4.
When the utility model connects, the attachment hole that the connection bump of connecting body B is pressed into connecting body A consists of two can counterrotating structure, the anti-skidding projection of connecting body B enters the anti-slip tank of connecting body A, making two connecting bodys relatively rotate to certain position is to realize anti-drop function by anti-slip tank, anti-skidding projection contacts with anti-slip tank and adopts the arc design, when twisting with larger power, anti-skidding projection is produced from anti-slip tank, connecting body A rotates the generation relative displacement with relative with connecting body B, Fig. 7 is the schematic representation of connecting body A and connecting body B folded position, be that anti-skidding projection and anti-slip tank angle are 0 degree state, at this moment anti-skidding projection is in anti-slip tank, consist of and prevent back taking off connection, Fig. 8 is the schematic representation of connecting body A and connecting body B deployed condition, be that anti-skidding projection and anti-slip tank angle are 180 degree states, at this moment anti-skidding projection is also in anti-slip tank, consist of and prevent back taking off connection, Fig. 9 is connecting body A and connecting body B schematic representation in vertical state, be that anti-skidding projection and anti-slip tank angle are 90 degree states, at this moment anti-skidding projection is not in anti-slip tank, can be freely movable between connecting body A and the connecting body B, find out that from above figure what the utility model can be realized two connecting bodys easily prevents back taking off connection.
After describing mode of execution of the present utility model in detail, the personage who is familiar with this technology can be well understood to, can carry out various variations and modification not breaking away under above-mentioned claim and the spirit, any simple modification, equivalent variations and modification that all foundations technical spirit of the present utility model is done above embodiment, the scope that all belongs to technical solutions of the utility model, and the utility model also is not subject to the mode of execution that gives an actual example in the specification.
