Description

A skeleton of a baby carriage

technical field

The utility model relates to a baby stroller frame, in particular to a baby stroller frame which is automatically positioned after retracting into the handle of the stroller, and does not stretch and rub against the floor after the stroller is retracted.

Background technique

At present, there is a popular stroller, as shown in Figures 1 to 3, which is characterized in that it can stand on its own when folded and the handle of the stroller is kept at waist height, so the user does not need to bend over or Crouch down to pick it up, and simply reach out and grab the handle to move it.

The stroller handle of this kind of baby stroller is specially provided with a telescopic block at the lower end, which can be kept locked into the concave part at the upper end of the front leg by using spring bias, so as to lock the stroller in the unfolded usable state; Utilize the detent assembly (such as a pull hook or a sliding sleeve) on the handle of the stroller to pull back the telescopic clamping block through the interlocking cable, so that the lower end of the handle of the stroller is detached from the clamp, so that the stroller can be folded.

Since the telescopic clamping block is biased by the spring and stretches outward, the telescopic clamping block will pop out immediately even if the user releases the catch assembly during the process of folding the stroller. As shown in Figures 4 to 6, when the user grabs and drags the folded stroller, due to the relationship of the angle, the tip of the telescopic block will wear down on the floor and become shorter gradually. If it is shortened to a certain extent, it will not be able to effectively snap into the concave portion at the upper end of the front leg, causing the stroller to be unable to be stably locked in an unfolded usable state.

Utility model content

In order to solve the above-mentioned problem that when the folded baby carriage is dragged, the telescopic block will wear the floor and cause it to be shortened and cannot be locked stably. The purpose of this utility model is to provide a baby carriage frame that can During the stroller process, even if the catch assembly has been released, the telescopic block will not pop out automatically, so that the tip of the telescopic block will not be scratched or shortened by the floor, which will affect the stability of the catch.

The utility model is realized in the following ways:

A baby stroller frame, at least including a front foot frame, a pushcart handle, a rear foot frame, a telescopic block, a brake assembly and a linkage assembly, the linkage assembly is connected to the telescopic block and the brake assembly Between, the upper ends of the front foot frame and the rear foot frame are pivotally connected to each other so as to pivot relative to each other, and the telescopic block is biased by the first elastic component to be slidably telescopic to the lower section of the cart handle, which is characterized in that: A positioning hole is provided on the handle of the trolley, and an elastic locking component is provided on the telescopic block, which can be inserted into the positioning hole.

The stroller frame of the present utility model also includes a first connecting rod and a second connecting rod, the first connecting rod is pivotably connected between the front foot frame and the stroller handle, and the second connecting rod is pivotally connected between the rear leg and the handle of the cart.

Preferably, a protrusion is provided on the second connecting rod, and when the stroller frame is unfolded to an unfolded usable state, the protrusion can be aligned with the positioning hole and press the elastic catch assembly back into the positioning hole to release the locking. switch.

Preferably, a recess is provided on the upper end of the front leg for the telescopic clamping block to snap into.

Preferably, the telescopic block is provided with a recess for accommodating the first elastic component.

Preferably, the elastic locking component is composed of a second elastic component connected with a protruding pin, and the end of the protruding pin protrudes out of the positioning hole through the second elastic component to generate the positioning of the retractable clamping block at the fully retracted position effect.

Preferably, the second elastic component is a U-shaped spring piece.

The stroller frame of the utility model is provided with a positioning hole on the handle of the stroller, and an elastic catch assembly is provided on the telescopic block, which can be inserted into the positioning hole. When the pull assembly is pulled, the telescopic block is completely retracted into the handle of the cart. Afterwards, the elastic catch assembly can be just aligned with the positioning hole to automatically lock the telescopic block in the fully retracted position. Even if the catch assembly has been released, the telescopic block will not automatically pop up again. When moving the folded stroller, the tip of the telescopic block will no longer scratch the floor or be shortened by the ground, which effectively solves the problem that the stroller cannot be stably locked in an unfolded and usable state.

detailed description

As shown in Figures 7 to 12, the stroller frame 1 of the present utility model at least includes: a front foot frame 2, a cart handle 3, a rear foot frame 4, a first connecting rod 5, a second connecting rod 6, A telescopic clamping block 7 , a detent assembly 8 , and a linkage assembly 9 . Wherein the upper ends of the front foot frame 2 and the rear foot frame 4 are pivotally connected and can pivot relative to each other, and the first connecting rod 5 is pivotably connected between the front foot frame 2 and the cart handle 3 . The second connecting rod 6 is pivotally connected between the rear foot frame 4 and the cart handle 3 , and the telescopic block 7 is biased by a first elastic component 71 to slidably expand and contract on the lower section of the cart handle 3 . As shown in Figures 8 and 9, when retracting the car, the user can pull the locking component 8, and the telescopic block 7 is pulled back by the linkage component 9, thereby releasing the locking between the front leg 2 and the cart handle 3, Start the entire car collection procedure.

As shown in Figures 7 and 9, the features of the stroller frame 1 of the present invention include: a positioning hole 31 is provided on the handle 3 of the stroller, and an elastic catch assembly 72 is provided on the telescopic block 7, which can be inserted into the stroller. The positioning hole 31 of the handlebar 3; by this, when the retractable block 7 is fully retracted into the cart handle 3 by pulling the detent assembly 8, the elastic latch assembly 72 can be aligned with the positioning hole 31 and the telescopic block can be automatically retracted. Block 7 is positioned in a fully retracted position 100 . As shown in Figure 10, with these features, once the user pulls and releases the latching assembly 8, the elastic latching assembly 72 will move with the telescopic clip 7 and snap into the positioning hole 31, so that the telescopic clip 7 is positioned completely Position 100 for indentation.

As shown in Figure 7, the elastic locking component 72 can be formed by connecting a second elastic component 721 and a protruding pin 722, and the end of the protruding pin 722 can protrude from the positioning hole 31 by the elastic force of the second elastic component 721 to generate a latch. The positioning function of the telescopic block 7 in the fully retracted position 100. The second elastic component 721 of this embodiment can be implemented as a general compression spring (not shown) or a U-shaped spring piece, and the protruding pin 722 is fixed on the end of the compression spring or the U-shaped spring piece. In this embodiment, the telescopic block 7 can be provided with a recess 723 for accommodating the first elastic component 71 . As shown in FIG. 12 , when the protruding pin 722 is snapped into the positioning hole 31 and the telescopic block 7 is positioned at the fully retracted position 100, the first elastic component 71 is in a compressed state. Once the latch is released, the protruding pin 722 is disengaged. In the positioning hole 31, the power of the first elastic component 71 will make the telescopic clamping block 7 stretch out and snap into the upper end of the front leg 2.
