detailed description

Referring to Figures 1 to 4, the present invention is a baby carriage that can be folded by pulling, including: rear leg tube 1, rear rollers are installed on the lower part of rear leg tube 1; first pivot block 2, slidably sleeved on the rear leg On the tube 1; the front leg tube 3, the front roller is installed at one end of the front leg tube 3, and the other end is pivotally connected with the first pivot block 2; the middle tube 4 of the seat is slidably inserted on the rear leg tube 1; the second pivot Block 5 is fixedly connected with seat middle tube 4; seat front tube 6 is pivotally connected with front leg tube 3 at one end and pivotally connected with second pivot block 5 at the other end; seat upper tube 7 is connected with second pivot block 5 pivotally connected; rear pipe 8, one end is pivotally connected with first pivot block 2, and the other end is pivotally connected with seat upper pipe 7; seat assembly 9 is installed on second pivot block 5 and seat middle pipe 4 The locking structure is arranged in the first pivot block 2, the rear leg tube 1 and the seat middle tube 4, and is used to lock the sliding between the first pivot block 2, the rear leg tube 1 and the seat middle tube 4.

The present invention adopting the above-mentioned structure uses the first pivot block 2 to slide down along the rear leg tube 1, and the seat middle tube 4 moves outward relative to the rear leg tube 1, and then drives other components to link to achieve the purpose of folding the present invention; In the present invention, a locking structure is provided to control the kinematic relationship between the first pivot block 2, the rear leg tube 1 and the seat middle tube 4. It can be seen from the above that the folding of the present invention only depends on the state of the locking structure , there is no other other control structure, so the present invention is very convenient to fold, as can be seen in the following locking structure.

As shown in the figure, the locking structure is preferably implemented in the following manner, including: a first through hole 101, which is arranged on the first pivot block 2; a second through hole 102, which is arranged on the rear leg tube 1; a third through hole 103, Set on the middle tube 4 of the seat; the locking block 104 can be inserted into the first through hole 101, the second through hole 102 and the third through hole 103, and the locking block 104 can be inserted into the first through hole 101, the second through hole 102 and the third through hole 103 When the three through holes 103, the present invention is in the locked state, and when the locking block 104 breaks away from the first through hole 101, the second through hole 102 and the third through hole 103, the present invention is in the unlocked state; the drive block 105, through an inclined plane device and The locking block 104 is connected, and the inclined plane device includes a groove 108 arranged on the driving block 105 and a roller 109 arranged on the locking block 104, and the roller 109 is inserted in the groove 108; a rope 110, one end is connected with the driving block 105 , the other end extends to the outside of the seat middle tube 4; the shell 106 is installed in the seat middle tube 4, and cooperates with the locking block 104 and the driving block 105 to limit the locking block 104 to only perform longitudinal linear movement and limit the driving block 105 can only move horizontally and linearly; one end of the return spring 107 leans against the locking block 104 , and the other end leans against the housing 106 .

By pulling the rope 110, the driving block 105 is driven to move upwards, and the driving block 105 drives the locking block 104 to withdraw from the first through hole 101, the second through hole 102 and the third through hole 103 to complete the unlocking action; When the driving block 105 is driven, the driving block 105 moves downward under the action of the return spring 107 , and then drives the locking block 104 to protrude from the third through hole 103 . In the present invention, the rope 110 can extend to the lower part of the seat. When the present invention needs to be folded, only need to reach out and pull the rope 110, and then press down the present invention to fold the present invention. The structure is simple, practical and easy to operate. Simple. The above-mentioned embodiments are only preferred versions of the present invention, and the present invention also has other embodiments. Those skilled in the art can also make equivalent modifications or replacements without departing from the spirit of the present invention, and these equivalent modifications or replacements are all included within the scope set by the claims of the present application.
