Embodiment for Implementing the Invention

[0019] Hereinafter, referring to the drawings related to the embodiments of the present invention, the technical configuration of the embodiments will be clearly and comprehensively described. Note that the described embodiments are only a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all embodiments obtained by those with ordinary knowledge in the technical field without creative labor are included in the protection scope of the present invention.

[0020] Embodiment The purpose of this embodiment is to solve the problems of the conventional support device for baby carriages and pet cars, such as lack of corresponding range and versatility, time-consuming assembly and disassembly, and the instability of the folded car body, which is prone to tipping and collision.

[0021] Referring to FIGS. 1 to 5, the support device for baby carriages and pet cars includes a support pillar 1 and a baby carriage frame 7. A cavity 2 is formed inside the support pillar 1, and a first rivet hole 3 and a second rivet hole 4 are respectively drilled in the outer wall of the support pillar 1.

[0022] A fitting assembly 5 is provided at the upper part of the support pillar 1. The fitting assembly 5 includes a first built-in pillar 51 inserted into the cavity 2, and a clamp base 54 is fixed to the upper end of the first built-in pillar 51. A clamp ring 55 is hingedly connected to the clamp base 54, and by fitting the clamp base 54 and the clamp ring 55, a holding space for clamping and holding the baby carriage frame 7 is formed.

[0023] As shown in Figure 2, anti-slip protrusions are provided on the inner walls of the holding spaces of the clamp base 54 and the clamp ring 55, arranged in the circumferential direction, and the cross-section of these protrusions is rectangular. A third rivet hole 52 is drilled in the first internal column 51, and the third rivet hole 52 is aligned with the first rivet hole 3, with a first blind rivet 53 fixed between the two holes. The upper end of the clamp ring 55 is provided with a pressing portion that protrudes outward in an arc shape, and a locking portion that protrudes downward in an arc shape is formed below the end. The clamp base 54 is provided with a concave locking groove that can be fitted into a position corresponding to the locking portion.

[0024] A support assembly 6 is provided at the lower part of the support column 1. The support assembly 6 includes a second internal column 61 that is inserted into the cavity 2, and a leg portion 62 is fixed to the lower end of the second internal column 61. A fourth rivet hole 63 is drilled in the second internal column 61, and the position of the fourth rivet hole 63 corresponds to that of the second rivet hole 4, and a second blind rivet 64 is fixed between the two holes.

[0025] The procedure for using this embodiment is as follows: As shown in Figure 4, during the manufacturing stage, the length of the support column 1 is specified and manufactured according to the required mounting height to the stroller frame 7 or pet car frame. At the same time, the dimensional parameters of the support column 1, the first internal column 51, and the second internal column 61 are precisely set in advance. As a result, when the first internal column 51 is smoothly inserted into the cavity 2 at the top of the support column 1, the third rivet hole 52 of the first internal column 51 is precisely aligned with the first rivet hole 3 on the outer wall of the support column 1, ensuring a seamless fit. Similarly, when the second internal column 61 is smoothly inserted into the cavity 2 at the bottom of the support column 1, the fourth rivet hole 63 of the second internal column 61 is precisely aligned with the second rivet hole 4 on the outer wall of the support column 1, ensuring a seamless fit.

[0026] In this state, the worker firmly secures the first rivet hole 3 and the third rivet hole 52 using the first blind rivet 53, and firmly secures the second rivet hole 4 and the fourth rivet hole 63 using the second blind rivet 64. This integrally connects the fitting assembly 5, the support assembly 6, and the support column 1. The two connection points between the first rivet hole 3 and the third rivet hole 52, and between the second rivet hole 4 and the fourth rivet hole 63, are completely fixed, preventing any looseness or misalignment after assembly. Furthermore, the support height of the device is maintained according to a pre-set standard, ensuring compatibility with the stroller and pet car frame of the corresponding model and guaranteeing stability during use.

[0027] When the user actually uses this device, they attach it to the handle of the stroller frame 7 or pet car frame, depending on the application. As shown in Figures 1 and 3, first, when the pressing part at the upper end of the clamp ring 55 is lifted by hand, the locking part at the lower part of the clamp ring 55 disengages from the concave locking groove of the clamp base 54. This causes the clamp ring 55 to open using the hinge part with the clamp base 54 as a pivot point, securing sufficient mounting space.

[0028] Next, the holding space formed by the clamp base 54 and the clamp ring 55 is placed over the handle portion of the stroller frame 7 or pet car frame. After confirming that the handle portion is stably and properly positioned within the holding space, the pressing part is pushed down in the opposite direction. This causes the locking part at the bottom of the clamp ring 55 to rotate around the hinge portion as a pivot point and engage with the concave locking groove of the clamp base 54. The clamp ring 55 and the clamp base 54 are firmly locked, the entire device is securely fixed in the predetermined position on the handle portion, and the installation is completed.

[0029] Furthermore, as shown in Figure 2, the inner wall of the holding space is provided with anti-slip protrusions with a rectangular cross-section that are evenly spaced in the circumferential direction. These protrusions increase the frictional force at the contact surface between the device and the handle, preventing relative slippage during use, improving connection strength, and suppressing loosening of the mounting.

[0030] To remove the device, lift the pressing portion at the upper end of the clamp ring 55 again, and release the lower locking portion from the concave locking groove of the clamp base 54. Then, by opening the clamp ring using the hinge portion as a pivot point, it can be easily removed from the handle of the stroller or pet cart, making the operation simple and quick. No special tools are required for assembly or disassembly, the procedure is easy to understand, increasing efficiency, reducing the burden on the user, and improving the user experience.

[0031] Furthermore, when the vehicle is folded and stored with this device attached to the handlebars, the position of the handlebars, which were originally off the ground, changes as shown in Figure 1. At this time, the legs 62 at the bottom of the device make stable contact with the ground, firmly supporting the folded vehicle. This prevents tipping or collision due to an imbalance in the center of gravity, protecting the vehicle and reducing safety risks. This device is particularly suitable for models where the handlebars are positioned high above the ground.

[0032] In this specification, ordinal terms such as "first," "second," etc., are used simply to distinguish one component or operation from another, and do not imply or suggest any actual order or relative relationship between them. Furthermore, "equipped with," "includes," and their derivatives are intended to indicate non-exclusive inclusion. Thus, a process, method, article, or apparatus that includes multiple components includes not only the components described, but also other elements not explicitly described, or elements inherent to the process, method, article, or apparatus.

[0033] The above are merely preferred embodiments of the present invention. A person with ordinary skill in the art may make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications shall also fall within the scope of protection of the present invention.
