DETAILED DESCRIPTION

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] Reference Figures 1 to 3A folding stroller includes a base 1, on which two first rotating rods 2 are symmetrically mounted for rotation. A first sliding seat 21 is provided at the top of each first rotating rod 2. A handle 3 is slidably mounted on the first sliding seat 21. A second sliding seat 31 is fixedly mounted at the bottom of each handle 3 and is slidably connected to the first rotating rod 2. Two second rotating rods 4 are symmetrically mounted for rotation on the base 1, and are rotatably connected to the second sliding seat 31. The top ends of the two handles 3 are fixedly connected via a crossbar. When folding, the handles 3 are slid downward and pressed downward, causing the handles 3 to rotate, causing the first rotating rods 2 and the second rotating rods 4 to fold relative to each other as the handles 3 retract. This makes operation simple and convenient.

[0026] As a preferred embodiment, the device further includes a clamping portion 5, which includes a pin 55. The pin 55 is slidably mounted in the second sliding seat 31. The first rotating rod 2 is provided with a through hole 22, which is adapted to fit the pin 55. When the stroller is fully deployed, the first sliding seat 21 and the second sliding seat 31 abut against each other. At this time, the pin 55 is inserted into the through hole 22, thereby securing the handle 3 and preventing the handle 3 from sliding relative to the first rotating rod 2.

[0027] As a preferred embodiment, a bracket 53 is fixedly mounted within the second sliding seat 31. The bracket 53 has an opening 54, and a spring 56 is disposed within the opening 54. The spring 56 abuts against the pin 55. A sliding frame 57 is slidably mounted outside the bracket 53. The sliding frame 57 has an inclined surface 58, and the pin 55 has a guide rod 59 abutting against the inclined surface 58. When the pin 55 needs to be moved, the sliding frame 57 is slid. The inclined surface 58 drives the guide rod 59 and the pin 55 upward, thereby moving the pin 55 away from the through-hole 22 and releasing the fixation between the handle 3 and the first rotating rod 2. When the pin 55 is lifted, the spring 56 is compressed to store energy. Conversely, the elastic force of the spring 56 can reset the sliding frame 57 and the pin 55, allowing the pin 55 to reenter the through-hole 22.

[0028] As a preferred embodiment, the handle 3 is a hollow structure with a notch 33 formed therein. A connecting shaft 34 is slidably mounted in the notch 33. An operating portion 51 is slidably mounted on the handle 3. The operating portion 51 is fixedly connected to the connecting shaft 34. A steel wire rope 52 is fixedly mounted on the operating portion 51, and the steel wire rope 52 is fixedly connected to the sliding frame 57. By operating the operating portion 51 to slide along the handle 3, the movement of the sliding frame 57 and the pin 55 can be conveniently controlled.

[0029] As a preferred embodiment, it further comprises a support frame 6 , which is movably mounted on the second sliding seat 31 .

[0030] As a preferred embodiment, a socket 32 ​​is fixedly mounted on the second sliding seat 31, a card hole 35 is opened on the socket 32, and an insert plate 61 is fixedly mounted on the bottom of the support frame 6, the insert plate 61 is adapted to the socket 32, an elastic portion 62 is provided on the insert plate 61, and a card block 63 is provided on the elastic portion 62. When the insert plate 61 is inserted into the socket 32, the card block 63 is carded into the card hole 35 under the elastic force of the elastic portion 62.

[0031] As a preferred embodiment, four universal wheels 11 are symmetrically provided on the bottom of the base 1 .

[0032] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
