Infant stroller handle device capable of telescoping and shrinking

Abstract

The utility model discloses an infant stroller handle device capable of telescoping and shrinking. The infant stroller handle device comprises a rear wheel foot pipe frame of which the rear side is obliquely connected and can be unfolded and folded, a front wheel foot pipe frame in which a stroller folding and unlocking part is arranged, wherein the rear wheel foot pipe frame and the front wheel foot pipe frame are telescopically combined together, a middle telescopic pipe frame of which the lower end is provided with a middle pipe unlocking part, a handle of which the lower end is provided with a folding handle telescopic driving part and a the telescopic unlocking pull rod component penetrating through the three components simultaneously, so that a user can twist or press a folding handle telescopic operation part arranged at the upper end of the handle with a single hand so as to drive different control cables. By the folding handle telescopic driving part, the height of the handlecan be telescopically adjusted, or after the handle is positioned, by pulling the telescopic unlocking pull rod part, and through a folding unlocking part, the rear wheel foot pipe frame is folded, and the handle is retracted into the middle telescopic pipe frame to push the middle pipe unlocking part at the tail end of the handle, and the middle telescopic pipe frame is retracted into the front wheel foot pipe frame together, so that the purpose of completely folding the stroller frame is achieved.

Description

technical field [0001] The present invention relates to baby carriages. In addition to the one-hand retraction operation, the telescopic adjustment of the appropriate height of the handle can also be carried out, and the operation of retracting the cart and the telescopic adjustment of the handle are all in the middle of the upper end of the handle. In the same place, it can be operated with one hand. Background technique [0002] Generally, the frame of baby stroller has a foldable design for easy storage, and at the same time, in order to facilitate the user to operate the frame with one hand, there is usually a handle in the middle of the handlebar. The car closing control device can achieve the purpose of car closing operation through the grip and pressure of the hand. The structure of the car closing control device is as announced in CN104828120B, CN103921822A, CN201619596U, CN202657083U, CN202703665U, CN205574030U, CN2474434Y, CN2513863Y...etc. As shown in the patent,...

Problems solved by technology

[0006] Therefore, in order to improve the operation of one-hand retraction of the known infant car frame and the operation of the height adjustment of the handlebar, the two cannot be at the same operating position, and it is impossible to realize the single-handed operation without moving the arm position. For the problem of telescopic adjustment of the hand retractable car and the handle, the present invention provides the upper end of the front wheel leg pipe frame, and sequentially passes through the middle telescopic pipe frame and the handle, so that the retractable car and the handle telescopic operation part set at the upper end of the handle After the twisting operation, pull to release the lock between the handlebar and the middle telescopic pipe frame, the handlebar can be adjusted telescopically, or perform the operation of holding and pressing the telescopic operation part of the handlebar, and pull to release the rear wheel After the leg frame is locked, it can be folded, and the handle is retracted into the middle telescopic pipe frame to push against the action. After the lock between the middle telescopic pipe frame and the front wheel leg frame is released, the middle telescopic pipe frame Then retract into the front wheel tube frame, and then achieve direct operation on the retractable and handlebar telescopic operation part, you can perform the telescopic adjustment of the handlebar with one hand, and the retraction of the rear wheel tube frame together with the handlebar, middle Condensation and other operations between the telescopic tube frame and the front wheel leg tube frame
