Fig. 1, 2, 3, 4, 5 and 6 show an embodiment of a folding structure of a stroller according to the utility model:
with reference to fig. 1, 2, 3, 4, 5 and 6, the folding structure of the stroller includes a push rod set, a combined joint linkage mechanism functional set, a frame bottom support set, and a seat platform set.
A push rod group: the lower push rod 11 is assembled and fixed on the combined joint 2, the outer diameter of the upper push rod 1 is smaller than that of the lower push rod 11, the upper push rod 1 can movably extend and retract in the lower push rod 11, and the end head of the upper push rod 1 is provided with an upper push rod collision head 12 for collision unlocking.
Function group of combined joint linkage mechanism: the combined joint 2 is fixedly provided with a lower push rod 11 and a hook lock 21, and is also provided with a first connecting rod 3, a front foot connecting seat 5 and a rear foot connecting seat 4.
The hook lock 21 is assembled in the combined joint 2, one end of the hook lock 21 is provided with a hook surface, and the other end of the hook lock 21 is provided with a hook lock spring 22. When in use, the hook surface plays a role of hanging the fixed lock rod 51 to achieve the combined locking function; similarly, the lower push rod 11 is also fixed in the combined joint 2, the upper push rod collision head 12 on the upper push rod 1 collides with a tail end device of the hook lock 21, and the hook surface is separated from the fixed lock rod 51 to achieve the unlocking function; when the plunger impact head 12 is not pressed against the hook lock 21, the unlocked immediate top can be locked by the force of the hook lock spring 22.
The combined joint 2 is also assembled and connected with a B axis point of the first connecting rod 3 and an A axis point of the front foot connecting seat 5 and the rear foot connecting seat 4, and B, A moves in linkage with each other when the combined joint 2 rotates.
Frame bottom sprag group: the first connecting rod 3 is hinged with a second connecting rod 31 and a third connecting rod 32. The second connecting rod 31 is hinged with a rotating pipe 41 fixed on the back foot pipe 42; the third connecting rod 32 is hinged with the front foot tube 52, and the third connecting rod 32 is hinged with the fourth connecting rod 61, and the hinged parts form a frame supporting part.
The B axis point of the first connecting rod 3 hinged with the combined joint 2 is required to be vertically below the ground at the A axis point of the combined joint 2 hinged with the front foot connecting seat 5 and the rear foot connecting seat 4, so as to achieve the main function of firmly supporting the hinged combined frame.
Seat platform group: two of the seat platforms 6 are hinged and are respectively hinged with the fourth connecting rod 61 and the front foot connecting seat 5.
When the frame is hinged and rotated, the third connecting rod 32 drives the fourth connecting rod 61 through the F shaft point, and the fourth connecting rod 61 pulls the seat platform to have a folding function through the G shaft point, so that the whole folding of the frame is easy to achieve and is small.
With reference to fig. 7 and 8, the trolley moves in the folded configuration:
folding the cart: the upper push rod 1 is compressed into the lower push rod 11, the collision head 12 of the upper push rod collides with the hook lock 21 to press down the rotary hook lock 21, and the fixed lock rod 51 on the hook fastening surface release hook is unlocked; the unlocked rear push rod group is pressed downwards under the action of external force, and when the combined joint 2 rotates, the first connecting rod 3, the second connecting rod 31, the third connecting rod 32 and the fourth connecting rod 61 are driven to perform linkage reaction, so that the rear foot tube 42, the front foot tube 52, the seat platform 6 group and the like are combined. The whole framework is in a rotating folding mechanism functional movement through the action of an A, B, C, D, E, F, G, H shaft point.
When the cart needs to be unfolded for use:
the push rod assembly is pulled up to rotate the combined joint 2, when the combined joint 2 rotates, the first connecting rod 3, the second connecting rod 31, the third connecting rod 32 and the fourth connecting rod 61 are propped to perform a propping reaction, and the rear foot tube 42, the front foot tube 52, the seat platform 6 and other groups are unfolded to perform a motion function. The whole structure is adopted, and the rotating unfolding mechanism movement is generated through the action of an A, B, C, D, E, F, G, H shaft point. Under the action of the hook lock spring 22, the hook surface of the hook lock 21 will be automatically hooked (locked) with the fixed lock rod 51, so as to achieve the function of unfolding and locking. The various hinges A, B, C, D, E, F, G, H provide a pivoting function during the folding and unfolding motion of the cart.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept of the present invention, which falls into the protection scope of the present invention.
