Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0028] This embodiment provides a handle linkage component for a handcart, such as... Figure 1 and Figure 2 As shown, the linkage is installed on the upright 4 of the handcart;

[0029] Linkage components include:

[0030] The second slider 2 has its first end 201 slidably connected to the column 4, and its third end 203 and fourth end 204 are respectively hinged to the trolley side frame 5 near the column 4.

[0031] Push rod 3, the end of which is fixedly connected to the second end 202 of the second slider.

[0032] This also includes the first slider 1;

[0033] The first end 101 of the first slider is fixedly connected to the column 4, and the second end 102 of the first slider is slidably connected to the push rod 3.

[0034] Specifically, the first slider 1 acts as a limiter for the push rod 3. When the user folds the trolley, the side frame 5 moves the second slider 2 downwards along the column 4, and the push rod 3 also moves downwards with the second slider 2, achieving a folding effect. At this time, the height of the push rod 3 is lower than the height of the trolley frame, improving the integrity of the folded design and facilitating storage. When the user unfolds the trolley, the side frame 5 moves the second slider 2 upwards along the column 4, and the push rod 3 also moves upwards with the second slider 2, achieving an unfolding effect. At this time, the height of the push rod 3 is greater than the height of the trolley. The first slider 1, acting as a limiter for the push rod 3, also moves downwards when the trolley is folded because it is fixed to the column 4. Since the first slider 1 and the push rod 3 are slidably connected, it does not obstruct the push rod 3's vertical movement.

[0035] The second end 102 of the first slider is provided with a first through hole 103, which is used for the push rod 3 to pass through and slide up and down along the inner wall of the first through hole 103.

[0036] The first end 101 of the second slider is provided with a second through hole 205, which is used for the column 4 to pass through and slide up and down along the inner wall of the second through hole 205.

[0037] Among them, push rod 3 includes upper push rod 303, folding mechanism 302 and lower push rod 301;

[0038] The upper push rod 303 is connected to the lower push rod 301 via the folding mechanism 302.

[0039] The lower push rod 301 is set parallel to the column 4 and is located inside the first through hole 103.

[0040] Among them, the height of the lower push rod 301 relative to the side frame 5 is greater than the height of the column 4 relative to the side frame 5.

[0041] Specifically, the linkage of the trolley components is achieved: through the cooperation of the second slider 2 and the push rod 3, the upright 4, side frame 5, and handle of the trolley are linked with the push rod, forming a linkage relationship between the components. When the handle is pushed or operated, the push rod 3 drives the second slider 2 to slide on the upright 4, thereby causing the side frame and other related components to move accordingly, realizing the coordinated action between different parts of the trolley and achieving functions such as folding or unfolding the trolley.

[0042] Specifically, the linkage mechanism of the handrail improves the ease of use of the trolley: the linkage structure allows users to perform the operation of multiple parts with simple operation, without having to operate each part separately, reducing operation steps and improving the convenience of using the trolley. When the trolley needs to be folded and stored, users can complete the operation more easily and quickly.

[0043] Specifically, by sliding the second slider 2 on the column 4 and sliding the push rod 3 up and down within the first through hole 103 of the first slider 1, the height of the push rod 3 and the connected handrail can be changed. Since the lower push rod 301 is parallel to the column 4 and located within the first through hole 103, when the push rod 3 is pushed or pulled, the second slider 2 will move up and down along the column 4, thereby causing the overall height of the handrail to change to meet the needs of different users for the height of the handrail of the trolley.

[0044] Specifically, the height of the lower push rod 301 relative to the side frame 5 is greater than the height of the upright 4 relative to the side frame 5, providing a larger height adjustment range for the handrail, making the overall height of the handrail more in line with the height requirements for pushing, and better meeting the pushing needs of users of different heights or in different usage scenarios.

[0045] Specifically, when the handrail height needs to be adjusted, the user only needs to operate the push rod 3. Through the linkage between the push rod 3 and the first slider 1 and the second slider 2, the handrail can be easily raised or lowered. Compared with some handrail height adjustment methods that require complex operations or individual adjustments to multiple components, this linkage structure reduces the number of operating steps and the amount of force required, reducing the effort required due to an unsuitable handrail height. The adjustable handrail height allows the user to adjust the handrail to the most suitable position for their exertion, so that the arm is in a more natural and comfortable posture when pushing the trolley, thereby reducing fatigue in the arm and other parts of the body, and further avoiding the effort required for operation due to handrail height issues.

[0046] Specifically, when folding the trolley, the linkage between the handle and the trolley body allows the folding action of the handle to coordinate with the folding action of the trolley body. When pushing or pulling the relevant parts to fold, the hinged relationship between the second slider 2 and the side frame 5 of the trolley, as well as its sliding connection with the column 4 and the push rod 3, ensures that the handle moves in a predetermined manner during the folding process without interfering with other parts of the trolley body, thus guaranteeing the integrity of the folded trolley.

[0047] Specifically, the height corresponds to the folded shape. The push rod 3, through the linkage between the slider and the upright column 4, ensures that the height of the folded handle corresponds to the height of the folded cart body. This means that after folding and storing, the trolley has a more regular shape, occupies less space, is easier to store, and improves the convenience of storing the trolley when not in use.

[0048] This invention avoids the issues of laborious operation and compromised folding integrity caused by the height of the handlebars by using a linkage between the handlebars and the vehicle body. The push rod in the linkage works in conjunction with multiple sliders and the vehicle body's uprights, ensuring that the overall height of the handlebars better matches the height required for pushing the vehicle, and that the overall folded height corresponds to the folded height of the vehicle body, guaranteeing folding integrity and facilitating storage.

[0049] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
